Insulin stimulation of nucleoside triphosphatase activity in isolated nuclear envelopes. | The activity of nucleoside triphosphatase, an enzyme that regulates nuclear messenger RNA transport, was measured in highly purified nuclear envelopes isolated from rat liver. Addition of picomolar concentrations of insulin to freshly prepared nuclear envelopes directly increased the enzyme activity. The major effect of insulin on this enzyme was to increase the maximum velocity of its activity; no significant effects were seen on the affinity constant. These studies raise the possibility, therefore, that the nuclear envelope is a site where insulin regulates nuclear functions. |
Clinical and laboratorial evidences of dental caries control with Chlorhexidine and Xylitol use | INTRODUCTION: The control of dental caries has been one of the mainly objectives of dentistry, mostly in specific populations, where the prevalence of this disease is still high. Chemical control has been widely studied as an extra strategy for patients with high risk or high prevalence of dental caries. From all chemical agents available in dentistry, chlorhexidine, an antibacterial, and xylitol, a sugar substitute, have been demonstrated expressive evidence for caries control. PURPOSE: The purpose of this paper is to review the literature about clinical and laboratorial evidences of dental caries control with chlorhexidine and xylitol. CONCLUSION: Chlorhexidine and xylitol separately or associated seem to have an excellent performance for Streptococcus mutans , biofilm and dental caries control. |
Analysis on loom weft insertion mechanism based on virtual prototype technique | In order to study the characteristics of dynamics and kinematics of the conjugate cam weft insertion mechanism,a virtual prototype machine was built using ADAMS software,and then the simulations on dynamics and kinematics of the conjugate cam weft insertion mechanism were conducted based on the virtual prototype machine.The continuous operation curves of dynamics and kinematics were obtained in the simulations.By improving the conjugate cam profile curve,a new curve of weft insertion motion was obtained from simulation.The improved profile curve will stabilize and improve the quality of weft insertion.The methods presented in this paper will provide an effective mean for analyzing and designing new type of looms or improving existing looms. |
The interactive dynamics of flow and directional solidification in a Hele-Shaw cell Part 2. Stability analysis and nonlinear simulations | A linear stability analysis as well as nonlinear simulations are performed in order to analyse the coupling between the directional solidification of a binary alloy and the flow in its melt. An incompressible, potential flow model is assumed, whose validity is tested through comparisons with the accompanying experiments of Zhang & Maxworthy in a Hele-Shaw cell. The linear stability analysis predicts that a uniform flow parallel to the interface reduces the growth rates of directional solidification instabilities. In addition, the dominant wavelength is shifted to larger values by the flow, and a small propagation velocity in the downstream direction is observed. These findings are confirmed by the nonlinear simulations as well |
The Stress‐Strain Characteristics of a Magnesium Alloy Beam | THE work described in this paper was undertaken to investigate the behaviour of a magnesium alloy beam clastically and plastically deformed by a uniform bending moment at room temperature. The object of the work was to obtain relations between stresses and strains in the beam, to afford a basis for design, in cases where it is required to submit magnesium alloy structures to bending stresses exceeding the elastic limit. |

On American Protestants' Educational Activities in Modern China | A typical educational activity of American Protestant missionaries in modern China is the running of missionary schools,which,as a particular cultural phenomenon in modern Chinese history,play a crucial role in promoting the modernization of Chinese higher education and the Sino-occidental cultural exchange.This paper is a probe into and review of the three stages of development for missionary schools. |
Notch signaling in lymphocyte development. | Cytokine and antigen receptor signals play well-characterized roles in promoting the survival and maturation of T and B lymphocyte progenitors through sequential developmental stages. Emerging studies suggest equally important roles for more ancient signaling pathways that evolved prior to the adaptive immune system in jawed vertebrates. In particular, there are at least two essential functions for the highly conserved Notch signaling pathway in lymphocyte development. First, Notch signals are essential for the development of T cell progenitors in the thymus and intestinal epithelium. Second, Notch signals are required to suppress B cell development in the thymus. This review will focus on focus on recent advances in our understanding of how Notch signaling regulates this developmental switch, as well as how Notch might regulate subsequent survival and cell fate decisions in developing T cells. |
Synthesis of single-walled carbon nanotubes in vibrationally non-equilibrium carbon monoxide | Single-walled carbon nanotubes (SWNTs) are synthesized in a gas-phase non-equilibrium plasma process.The carbon producing CO disproportionation reaction is driven very efficiently in a flow reactor, in which extreme disequilibrium between the vibrational and translational mode of the carbon monoxide gas is maintained even at low translational temperatures by using a powerful and efficient carbon monoxide gas laser.In the presence of metal catalysts, the vibrationally excited CO reacts to form CO2 and structured carbon molecules, notably SWNTs.The individual tubes form ropes or flat ribbons and these are aligned parallel to each other into larger structures of SWNT material without any post-synthesis treatment. 2002 Published by Elsevier Science B.V. |
Paleomagnetism on the Quaternary marine sediment at the DH-1 long-core site in the Korean continental margin of the East Sea | A long core of 23.6 m was acquired in the Korean continental margin of the western East Sea. The core site of the DH-1 is located in the offshore of the Donghae City and the water depth is 357.8 m deep. In this area, the paleomagnetism and magnetostratigraphy were firstly reported using 420 samples collected from the long-core sediments. Based on the inclination distribution of the depositional remanent magnetization, the DH-1 core could be divided into two upper and lower units at the boundary of 1750 cm below seafloor. The upper unit is characterized by a positive polarity, whereas the lower unit by a negative polarity. The boundary of the upper and lower units was interpreted as the Brunhes-Matuyama boundary (778 ka). The chemical components of tephra layer at 2014 cm below seafloor belong to alkaline series, plotted between the tephra components of the Mount Baekdu and Ulleung Island. |
Synthesis, properties and structures of some lanthanide nitrate complexes with N-butylcaprolactam, Ln[CH2(CH2)4CONC4H9]3(NO3)3 | Abstract Some lanthanide nitrate complexes with N-butylcaprolactam of general formula Ln( CH 2 (CH 2 ) 4 CON C4H9]3(NO3)3 have been prepared and characterized by means of elemental analysis and IR spectra. The crystal and molecular structures of Tm[ CH 2 (CH 2 ) 4 CON C4H9]3(NO3)3 and Nd[ CH 2 (CH 2 ) 4 CON C4H9]3(NO3)3 have been determined by single-crystal X-ray diffraction. The two complexes are isostructural and crystallize in the monoclinic system, space group P21/c. Thulium(III) [Nd(III) is coordinated thorugh three carbonyls of three organic ligands and the three nitrates are all bidentate ligands. So each Tm(III) [Nd(III)] is coordinated by nine oxygens, which form a distorted tricapped trigonal prism. |
On the comparison of PBIB designs with two associate classes | A method to compare two-associate-class PBIB designs is discussed. As an application, it is shown that ifd* is a group-divisible design withλ2=λ1+1, a group divisible design with group size two andλ2=λ1+1>1, a design based on a triangular scheme andv=10 andλ1=λ2+1, a design with anL2 scheme andλ2=λ1+1, a design with anLs scheme,v=(s+1)2, andλ2=λ1+1, wheres is a positive integer, or a design with a cyclic schemev=5, andλ1=λ2±1, thend* is optimum with respect to a very general class of criteria over all the two-associate-class PBIB designs with the same values ofv, b andk asd*. The best two-associate-class PBIB design, however, is not necessarily optimal over all designs. |
Synthesis and Some Applications of Schiff Base Surfactants | Schiff bases derived from the condensation reaction of benzaldehyde or anizaldehyde and diethylenetriamine were prepared. The products were neutralized with palmatic acid to pH 7. The chemical structures of the prepared compounds were confirmed using elemental analysis, FTIR, and 1H NMR spectroscopy. Various surface properties of the synthesized surfactants were evaluated particularly, critical micelle concentration, effectiveness, efficiency, maximum surface excess, and minimum surface area. These surfactants were also evaluated as corrosion inhibitors and biocide agents Gram positive and Gram negative bacterial strains. The rheological properties and the filter loss for oil-based mud (invert-emulsion mud) were evaluated. The result showed that they were good emulsifiers and filter loss control agents for oil-base mud. It was determined that they have good corrosion inhabitation for low carbon steel alloy and good bactericidal effect. |
Negative transconductance via gating of the quantum well subbands in a resonant tunneling transistor | Operation of a new resonant tunneling transistor is reported in the AlGaAs/GaAs material system. The device contains an undoped quantum well collector separated from a heavily doped emitter by a thin tunnel barrier. The collector is gated and the gate field controls resonant tunneling characteristics ‘‘from behind’’ via a combination of the generalized Stark effect and the quantum capacitance effect. The common‐collector characteristics show negative differential resistance at a fixed gate bias and negative transconductance at a fixed emitter bias. Excellent agreement is found between the measured and calculated shifts of the peaks of the current‐voltage characteristics. |
On relations between zeros of Galois polynomials | A conjecture ofH. Kleiman says that over certain fields a Galois equation of degree ≥3 is uniquely determined by its root polynomials. We prove this conjecture for prime degrees ≥3 and a somewhat smaller class of fields than Kleiman's. In this situation, the ideal of all relations between zeros of the equation has a basis containing root polynomials only, not the equation itself. Giving a large class of counterexamples of degree 4, we disprove Kleiman's conjecture in general. |
THE ALBANIAN CUSTOM’S RIGHT IN HISTORICALJURIDICIAL ASPECT, A NOTE ABOUT LEKE DUKAGJINI AND SKANDERBEG’S CODE | The article aims at treating what the Albanian custom’s right is, the historical and social conditions of its birth and its implementation. As well, it stops on the historical evolution of this right and on the considerations of some foreign and Albanian authors about it. The analysis is focused only on the codes of Leke Dukagjini and that of Scanderbeg, as two of the most important ones which acted in the north of the country, in Dukagjins’ and Kastriots’ principates. Their content and their composition as well as their basic features are described in the article. Special attention is dedicated to the originality of the Albanian custom’s right, considering these codes as moral codes, ethical and juridical codes with its institution, such as: the institute of Oath, hospitality, etc. |
The evolution of the anatomically modern or advanced Homo sapiens: time, place, process, affinities and variations. | This paper surveys the opinions expressed in the recent literature on the origins of the anatomically- modern Homo sapiens, and reviews the evidence from cranial and dental morphology argued by proponents of opposing views to support their case. It also critically analyses problems facing the interpretation of the evidence in arriving at a definitive conclusion to the debate. |
Achalasia of the oesophagus: Treatment with pneumatic dilatation | A series of 51 patients with achalasia of the oesophagus treated by pneumatic dilatation between 1980 and 1988 is reported. Treatment was assessed as effective (no or minimal dysphagia) in 78% of patients, followed for a mean of 30 months. Thirty-four patients required only one dilatation and only two patients had more than 3 dilatations. There were no deaths, but perforation occurred in seven patients, four of whom required early surgical repair. A further five patients were referred for elective surgery. Factors possibly contributing to oesophageal perforation are discussed. |
H2N4: Packet forwarding on hierarchical hash-based names for content centric networks | In this paper, we propose a novel solution to scalable forwarding problem in content centric networks (CCN) that relies on the use of hash-based content names for packet forwarding. Proposed approach continues the hierarchical naming format of CCN by converting human readable name prefixes to their hashbased counterparts to enable faster packet processing at the content routers, with additional proposed modifications at the edges to support hash-based forwarding. We present an in-depth study of the proposed architecture using numerical analysis that rely on actual datasets and realistic performance measures. Our results suggest significant improvements in storage requirements and processing overhead with the proposed architecture to support higher line rates and more efficient resource usage in the network. |
Exact and approximation algorithms for sorting by reversals, with application to genome rearrangement | Motivated by the problem in computational biology of reconstructing the series of chromosome inversions by which one organism evolved from another, we consider the problem of computing the shortest series of reversals that transform one permutation to another. The permutations describe the order of genes on corresponding chromosomes, and areversal takes an arbitrary substring of elements, and reverses their order. |
Dynamics of a laminated composite beam with delamination and inclusions | In this work numerical and experimental study of the dynamic behaviour of a composite laminated beam having delamination is presented. The model of delamination takes into account a contact interaction between sublaminates including normal forces, shear forces and additional damping. In order to verify the model special samples of multilayered beams have been manufactured. Small parts of adjacent layers have been cut and replaced by inclusions from different materials modelling delamination. The mechanical properties of the inclusions have been considered during the numerical calculations. The beams were subjected to a short pulse loading and then their response was registered. The results from the numerical simulation were in a good agreement with the experimental results. The significance of the additional damping due to delamination on the response of the beam was confirmed numerically and experimentally. |
Throughput comparison of optical and digital correlators for automatic target recognition | Correlation provides an effective approach for recognizing targets embedded in a large field of view containing noise and clutter. Correlation is implemented either digitally or optically. When implemented digitally, correlation (consisting ofrepetitive multiply and accumulation operations) is directly realized with digital multipliers and accumulators (MAC), specialized signal processors or general computers. When the input record length is long, digital correlation is implemented in the frequency domain. Fast correlation is achieved because of the existence of the computational efficient fast Fourier transform (FFT) algorithm and specialized hardware for the discrete Fourier transform (DFT). |
Study on bending properties of poly (D,L-lactide) by equal channel angular extrusion(ECAE) | Poly(D,L-lactide) were processed by Equal Channel Angular Extrusion (ECAE).Comparing to moulding sam- ples,ECAE have remarkably affect on bending strength of the PDLLA.The bending strength of the samples increases with the increase in ECAE temperature,and it reaches 164 Mpa at 75℃.The bending fracture of poly(D,L-lactide) is changed from brittle failure of original sample to ductile fracture after processed by ECAE. |
The Effect of Marketing Strategy on Sales Performance: The Moderating Effects of Internal and External Environment | How does marketing strategy affect sales performance as for internal and external environment? The aim of this study is to identify performance implications of marketing strategy and moderating effects of transformational leadership, demand uncertainty and competitive intensity on sales performance. This study is a mixed research that combines qualitative and quantitative methods. The population entails sales and marketing managers of companies in food industries that are members of Tehran stock exchange. The sample size in qualitative and quantitative study was 23 and 66 respectively. Analyses of survey and secondary data provide evidence that marketing strategy has a positive and meaningful relationship on sales performance while transformational leadership and competitive intensity were found to exert moderating effects on this relationship. |
Hot electron impact excitation cross-section of Er3+ and electroluminescence from erbium-implanted silicon metal-oxide-semiconductor tunnel diodes | We have demonstrated the 1.5 μm electroluminescence from implanted Er ions inside the SiO2 insulator of a silicon metal-oxide-semiconductor structure under forward bias. The Er ions are excited by the direct impact from electrons tunneling through the oxide at electric fields larger than 6 MV/cm. Under these conditions, we measured an excitation cross-section of 6±2×10−15 cm2 and a lifetime of the excited 4I13/2 level of 1.5 ms. |
A PSO algorithm based two-degree-of-freedom IMC scheme for large time-delay process | With the aid of double-controller design concept and particle swarm optimization (PSO) algorithm, an internal model control (IMC) scheme with two-degree-of-freedom (TDF-IMC) based on PSO algorithm (PSO-TDF-IMC) is proposed, which is capable of controlling large time-delay processes. This method takes integral time absolute error (ITAE) index as objective function and uses PSO algorithm to optimize IMC filter time constants. Simulation results show that the presented PSO-TDF-IMC scheme has such advantages as simplicity for algorithm, fast searching speed and high efficiency, which can greatly improve the performance and robustness of TDF-IMC controller. |
Diagnosis and surgical treatment of metastatic lesions of the long skeletal bones | The article describes peculiarities in the clinical course of metastatic lesions of the long skeletal bones. On the basis of literature data, the main diagnostic criteria of bone metastases are shown and the surgical stage in the treatment of patients with this pathology is described. The main kinds of surgical interventions for bone metastases are listed. |
Electrical connectors and receptacle assemblies having retention inserts | An electrical connector (12) includes a housing (48) extending from a mating face (50) to an opposite face (52), and first and second side walls (54, 57) that extend between the mating face and the opposite face. The housing has a contact cavity (62) that includes opposing sides (68, 70). The contact cavity is accessible through the mating face for receiving a mating connector (14) therein. Electrical contacts (40) are held by the housing and arranged in opposing rows (42, 44) that extend along the opposing sides (68, 70) of the contact cavity. A side opening (78) that extends through the first side wall (54) into communication with the contact cavity (62). A retention insert (56) is received within the side opening. The retention insert includes fingers (102) that extend into the contact cavity and engage in physical contact with corresponding electrical contacts (40) of one of the rows of the electrical contacts to hold the corresponding electrical contacts within the contact cavity. |
Characterization of the Atmospheric State above the SGP Using Raman Lidar and AERI/GOES Measurements | We have developed and implemented automated algorithms to retrieve profiles of water vapor mixing ratio, aerosol backscattering, and aerosol extinction from Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) Raman lidar data acquired during both daytime and nighttime operations. This Raman lidar system is unique in that it is a turnkey, automated system designed for unattended, around-the-clock profiling of water vapor and aerosols (Goldsmith et al. 1998). These Raman lidar profiles are important for determining the clear-sky radiative flux, as well as for validating the retrieval algorithms associated with satellite sensors. Accurate, high spatial and temporal resolution profiles of water vapor are also required for assimilation into mesoscale models to improve weather forecasts. |
Collective modes of anisotropic narrow-band Bloch-electron superconductors with nearest-neighbor pairing interaction. | On the basis of the phenomenological tight-binding model with the intersite pairing interaction, the collective modes of the anisotropic narrow-band superconductors consisting of Bloch electrons are investigated within the ladder-diagram approximation with the vacuum-polarization correction. For the extended [ital s]- and [ital d]-wave states on a two-dimensional square lattice, the velocity of the sound mode for the artificial neutral system and the energy of the plasma mode for the charged system are calculated as functions of hole density at [ital T]=0. Both of them depend on hole and electron densities symmetrically, and are almost unaffected by the anisotropy of the order parameter. The main term in the sound-velocity expression is shown to have the generalized form of the standard hydrodynamic expression. The plasma-energy expression almost coincides with that for the normal-state Bloch electrons. Possible additional approximations are examined. |
A statistical blind technique for recognition of internet traffic with dependence enforcement | The increasing demand of network security, access control, and service differentiation over IP networks drives Internet Service Providers and network administrators to deploy ever more sophisticated and faster traffic recognition mechanisms. Unfortunately this is complicated by the continuous development of new application protocols, increasing network bandwidth, and spreading of complicated tunneling and encryption techniques. In this paper we describe a statistical technique for blind recognition and classification of application sessions amongst aggregated traffic. Packets are assigned to known applications/protocols on the basis of a restricted set of information extracted from each packet: packet addresses, sizes, and timestamps. We analyzed three modes with different degrees of correlation among packets belonging to the same session. Albeit its simplicity, the studied technique has demonstrated very good performances, also when used for real-time classification. |
On the possible existence of hydrogen ions in solid rare‐gas crystals | Bondybey and Pimentel [J. Chem. Phys. 56, 3832 (1972)] have reported infrared absorptions in the spectra of rare‐gas solids doped with hydrogen. Some possibilities as to the nature of the absorbing species, such as H and D neutral atoms and H− and D− ions, are suggested by the authors of the latter paper. We discuss the possibility that H− and D− ions are the species responsible for the observed data. |
Planning Policies, Market Processes and Public Attitudes: Evidence from Central Perth | Australian central cities have undergone fundamental changes during the last decade. They have typically experienced massive office construction, while losing much of their residential communities, architectural and cultural heritage, retailing role and some recreational attractions. Government authorities have facilitated and participated in many central city projects. A metropolitan-wide survey conducted in Perth on these subjects shows increased dependence on the private car, increased preference for suburban living and shopping, but some willingness to consider central city living, a demand for further community participation in central city planning, and a preference for the future expansion of most non-office activities in the central area. The survey indentified notable gaps between government policies for the development of Perth's central area on one hand, and the preferences of Perth's residents on the other. |
8 Gb/s subcarrier multiplexed coherent lightwave system | The authors describe the first wideband coherent detection optical communications systems using two microwave subcarriers to transmit 8 Gb/s with an RF bandwidth efficiency of 1 b/s/Hz. It is demonstrated that two subcarriers each carrying 4 Gb/s QPSK (quadrature phase shift keying), compactly spaced at just twice the data rate, can achieve a receiver sensitivity ( eta P) of -26.5 dBm with as little as 0.5 dB crosstalk between subcarriers. The results are within 11 dB of the shot noise limit. > |
Inhibition of biological activity of mouse beta-nerve growth factor by monoclonal antibody. | A continuous hybrid cell line was derived that secretes monoclonal antibody capable of inhibiting the biological activity of mouse beta-nerve growth factor (beta-NGF). Results obtained with monovalent fragments indicate that the monoclonal antibody inhibits activity by interfering with the direct interaction between beta-NGF and the cell membrane receptor rather than by precipitating the dimeric form of beta-NGF. This monoclonal antibody binds to an antigenic determinant common to mouse beta-NGF, snake venom (Naja naja) beta-NGF, and human beta-NGF. These antibodies should provide specific molecular probes for a variety of studies of nerve growth factor including its tissue distribution and mechanism of action. |
Problems and Options in Ecotourism Development in the Poor Area in China | A lot of ecotourism attractions exist in the poor area in China, so ecotourism is often chosen as the main industry to be developed in Western China. But many problems involved ecology, society, culture, economic structure of tourism appeared. The only choice is applying for sustainable development, i.e., to protect the ecological environment and aestheticism, establish proper ecologic structure of tourism, and pursue the sustainable development of nature, culture, living environment of human beings and tourism. |
Carboplatin in patients with advanced colorectal cancer pretreated with fluoropyrimidines. | The activity of carboplatin (CBDCA) was tested in 21 consecutive patients with advanced colorectal cancer that had progressed during fluoropyrimidine therapy. CBDCA was chosen in view of the favourable results obtained in previous phase II studies. We were unable to find any activity of the agent which was given every 21 days at a dose of 400 mg/m2. The main toxicity was haematological. CBDCA is not recommended in pretreated patients with colorectal cancer. |
Thickening Mechanism of Hydrophobically Associating Polyacrylamide and Polyacrylamide | Compared with conventional polyacrylamide(HPAM),hydrophobically associating polyacrylamide(HAPAM) has the performance of increasing viscosity,salt tolerance and temperature stability.By measuring the conductivity and viscosity of the polymer at its various concentrations,the critical micelle concentration of HAPAM of 450 mg/L was obtained.By analyzing the results of IR and NMR,it is confirmed that HAPAM contained long alkyl chains with double bonds,which constitute the hydrophobic group.By the method of scanning electron microscopy,the viscosity mechanisms of HPAM and HAPAM were directly shown.The apparent viscosity of HPAM is mainly composed of non-structure viscosity ηn,while the apparent viscosity of HAPAM is composed of both ηn and structure viscosity ηs. |
Exploring the home environment: fusing rubbish and design to encourage participant agency and self-reflection | This paper presents an in-home design study investigating the resource conservation strategies of 40 frugal households located across urban and regional Australia. The purpose of this paper is to reflect on the method of design to explore the home environment, discussing how this approach may benefit researchers looking to investigate the home. We provide a reflexive account of the design process undertaken in this study, and present a discussion into the benefits of using this approach. The contribution of this paper reflects on two main aspects: 1) Designing for the culture of the home; and 2) Using design to encourage participant agency and self-reflection. |
Cooperative Research and Development Agreements (CRADAs) | A Cooperative Research and Development Agreement (CRADA) is a mechanism established by P.L.99-502, the Federal Technology Transfer Act, to allow the transfer of technology, knowledge, and expertise from government laboratories to the private sector for further development and commercialization. It also provides a means for federal scientists and engineers to obtain state-of-the-art technical information from the industrial community. The work done under a CRADA must not detract from the mission responsibilities of the laboratory. The government provides support in the way of overhead for research and development (R&D) performed in the federal laboratory and is prohibited from providing direct funding to the partner in the collaborative effort. Currently, over 5,000 CRADAs have been signed (including NASA Space Act Agreements). As the 106 Congress begins the debate over its approach to science and technology, the role of CRADAs is expected to be discussed within the context of federal support for R&D. |
Attitudes and psychological characteristics of suicidal individuals. | The study of suicidal behavior is so complex that the search continues for clues that might explain why some people make successful suicide attempts on their lives. In this article, the authors describe attitudes and psychological characteristics of suicidal psychiatric patients and university students in Transkei. Using a specially designed suicide proneness inventory, the authors describe three factors associated with suicide proneness in Transkei, namely, Suicidal Ideation, Feeling Abandoned, and Lack of Self-Esteem. The findings suggest that suicide wishes are probably more prevalent in the general population than clinical evidence might suggest. Also, it appears that the two most important factors associated with high risk for suicide are a person's inability to cope with stressful situations and a negative personal attitude toward life. |
Modulation of Norepinephrine Release by ATP and Adenosine | The evidence is substantial that adenyl purines such as ATP and adenosine can reduce the release of norepinephrine from adrenergic nerves (Paton, 1979; Fredholm and Hedqvist, 1980; Su, 1983). The general notion has been that the effects of adenine nucleosides and nucleotides are mediated by prejunctional P1-purinoceptors (Burnstock, 1985). Because nucleotides are generally found to be poor P1-receptor agonists, the prejunctional actions of ATP and other nucleotides are suggested to occur because of metabolism to adenosine which then acts via P1-receptors. |
Postpubertal cherubism with Noonan syndrome. | Cherubism is a self limiting, autosomal dominant, fibro-osseous lesion of the maxillo facial region affecting the young adults. The etiology is considered to be a mutation of the SH3BP2 gene from chromosome 4p16.3. Sporadic non-familial cases have also been reported. The affected subjects usually present with simultaneous, bilateral swellings of the maxillae and/or mandible, premature loss of primary teeth, malocclusion due to disturbed eruption pattern of permanent teeth and a characteristic chubby faced angelic eyed appearance. This usually presents as an isolated finding, however, it can exist in association with syndromes like Noonan's syndrome, Jaffe syndrome, Gardener syndrome and Ollier's disease. Treatment is focused on the exact genetic diagnosis and management of symptomatic conditions utilizing cosmetic surgery and orthodontics. Genetic counselling of the affected families may help to decrease its incidence. This report presents a rare case of cherubism with associated features of Noonan syndrome. |
A New f(R) Model in the Light of Local Gravity Test and Late-time Cosmology | We propose a new model of f(R) gravity containing Arctan function in the Lagrangian. We show here that this model satisfies fifth force constraint unlike a similar model in 2013 by Kruglov. In addition to this, we carry out the fixed point analysis as well as comment on the existence of curvature singularity in this model. The cosmological evolution for this f(R) gravity model is also analyzed in the Friedmann–Robertson–Walker (FRW) background. To understand observational significance of the model, cosmological parameters are obtained numerically and compared with those of Lambda cold dark matter (ΛCDM) model. We also scrutinize the model with supernova data. We apply Om diagnostic given by Sahni et al. in 2008 to the model. Using this diagnostic, we detect the distinction between cosmic evolution caused by the f(R) model and ΛCDM. We find best-fit parameter values of the model using baryon acoustic oscillations data. |
A review of moisture diffusion coefficients in transformer solid insulation - Part 2: Experimental validation of the coefficients | The objective of this article is to experimentally verify the diffusion coefficients proposed by the various researchers. To validate these coefficients, drying experiments were carried out on impregnated and nonimpregnated paper and on pressboard samples. Taking into account the characteristics of the tested samples, two different experiments were performed: For nonimpregnated insulation, thermo-gravimetric experiments were performed determining the weight of a sample while being dried. . For impregnated paper, drying experiments were carried out in hot oil in which samples were periodically extracted and analyzed by the Karl Fischer method. The drying experiments were simulated using a diffusion model [2], solved by finite element analysis. The simulations were carried out using the diffusion coefficients proposed by the various researchers. Finally, the experimental results were compared with the simulated ones, and the accuracy and the range of application of the various coefficients were determined. |
iTap vs. Air Mouse : A WOiP Head 2 Head | Using the iPhone and iPod Touch as a wireless remote is something many have thought of and there are plenty of options in the App Store to do just that. Two applications, however, stand out in terms of price and quality: iTap and Air Mouse. They both... |
A wide band-pass filter of broad angle incidence based on one-dimensional metallo-dielectric ternary photonic crystal | A wide band-pass filter has been presented based on one-dimensional metallo-dielectric ternary photonic crystal. ZnS, Ag and MgF2 are used as the materials of the photonic crystal. The forbidden and allowed bands of the photonic crystal are determined by using the band-edge analysis. The result indicates that the filter has a wide pass band in the visible region and it can block ultraviolet and infrared light. Simulation of the transmission spectra shows that the filter has decent transmittance in the pass band at broad angle incidence ranging from 0° to 70°, which can meet the need of practical use. |
FEMALE DOMINANCE AND MATERNAL INVESTMENT IN STREPSIRHINE PRIMATES | Prenatal maternal-investment rate (litter weight divided by gestation) was found to be the best available predictor of female dominance in primates. The female-dominant Malagasy lemurs are unique in their combination of a relatively low basal metabolic rate and a relatively high rate of prenatal maternal investment. The relationship between maternal investment and basal metabolic rate in strep-sirhines supports the hypothesis that lemurs raise their basal metabolic rate during reproduction and suggests that this increase is on the order of 75% or more. |

Reading Disturbances in the Presence of Oculomotor Disorders | Relations between reading disturbances and oculomotor disturbances are discussed. It is shown that disorders of eye movements may produce reading disturbances in different ways. By comparison, some cl |
Growth mode of tin on a niobium substrate | Abstract The initial stages of the growth of a tin film on a clean niobium substrate have been studied. The tin was evaporated slowly and the Auger signals of both the substrate and the tin overlayer were monitored as a function of the exposure time. The experimental results have been plotted as an AA– t plot for comparison with theoretical models of the different possible modes of the growth of films. The plot was also used to determine the attenuation length of the Sn and Nb Auger electrons. |
Comparison of Utilization of Medical Services by Alcoholics and Non-Alcoholics | To determine whether medical costs for alcoholics are higher than those for non-alcoholics, inpatient and outpatient costs for medical services of 191 alcoholics with 191 non-alcoholic matched controls were compared over four years. Results confirm that alcoholics are higher-cost users of medical services than non-alcoholics. (Am J Public Health 1982; 72:600-602.) |
Photoinduced valence instability in the organic molecular compound tetrathiafulvalene-p-chloranil (TTF-CA) | It was found that a local charge-transfer excitation on the donor(D)-acceptor(A) pair leads to a semimacroscopic valence change from the quasi-ionic (${\mathit{D}}^{+}$${\mathit{A}}^{\mathrm{\ensuremath{-}}}$) to quasineutral (${\mathit{D}}^{0}$${\mathit{A}}^{0}$) states in organic molecular-compound TTF-chloranil with mixed DA stacks. Photogenerated neutral-ionic domain walls, which are responsible for anomalous photoconductivity, show the temporal annihilation due to the one-dimensional recombination. |
Nonlinear age-dependent population growth with history-dependent birth rate | Abstract In this paper an age-structured population model is formulated in which the age-specific fertility rate depends on the past history of the population. Existence and uniqueness results and a priori estimates for the solutions are obtained. Moreover the dependence of the population upon the past history is investigated. |

A targeted, image-guided and dually locked photoresponsive drug delivery system. | We have developed a new targeted image-guided photoresponsive drug delivery system (DDS) based on a dual locking strategy. Excitation of the DDS by fluorescent light results in the first unlocking and activation of the drug, and allows real-time monitoring of the prodrug. Extended irradiation results in a second unlocking, giving drug release within cancer cells. |

Ferrofluid particle size distributions from magnetisation and small angle neutron scattering data | Abstract The particle size distributions of three ferrofluids have been determined at room temperature from magnetisation and small angle neutron scattering measurements. The distributions were calculated using a data analysis technique based upon the concept of maximum entropy, and their significance estimated using an adaptation of the Backus-Gilbert technique. |
Genetic Differentiation among Iranian Christian Communities | From some 500 members of Christian communities in Iran (Armenians and Assyrians from six localities), blood specimens were obtained and examined for a number of blood group, red cell enzyme, and serum protein systems. The results indicate the relatively closed nature of the Christian community as a whole but that moderate differentiation has already occurred among the local groups. One factor in this diversification process that can be distinguished is the effect of urbanization in Tehran, but otherwise it seems to be largely random. |

COMPUTERIZED PLANNING OF URBAN BUS SYSTEMS. ACADEMIC CONFERENCE PROCEEDINGS OF INTERNATIONAL CONFERENCE AND EXHIBITION ON ROAD TRANSPORT, BEIJING, CHINA, 7-12 MAY 1989 | VIPS, a computer package for public transport which was first demonstrated by Volvo Company of Sweden in 1974, is a simulation model estimating the behaviour of public transport passengers. The emphasis of this model is laid on the movements of people rather than those of vehicles. It is a computer model meant to be operated by transport planners rather than by computer specialists. It not only offers a broad analysis of a transport system that estimates passenger volumes, but also assesses the productivity and cost of public transport operations. 15 evaluation reports can be obtained by inputting relevant data. VIPS II has now been developed. (Author/TRRL) |
Fault-tolerant electric drive for an aircraft nose wheel steering actuator | This study describes the design and testing of a dual-lane electric drive for a prototype, electromechanically actuated, nose wheel steering system for a commercial aircraft. The drive features two independent motor controllers, each operating one-half of a dual three-phase motor, resulting in an actuator capable of full performance following an electrical fault. An isolated communications link between controllers allows parameter consolidation to identify faults and to synchronise outputs, ensuring even load sharing. A selection of results is presented from motor dynamometer performance analysis and from fully loaded output tests, performed on a hydraulic load rig at Airbus, UK. |
Rearranging the Files: On Interpretation in Media History | In this essay the author argues for the necessity of self-conscious interpretation in historical scholarship. Historical documents are traces, to use Jacques Derrida's term. They point to absences, events that once were but now are not. Building on Derrida's concepts (without accepting his entire theory of language), alongside historiographic theory and ideas about method from the critical sociology tradition, the author argues that the work of classification and transversal thought offers an alternative to realist historiographies, one that allows for attention to the process of interpretation while affirming the need to continue writing history that makes claims on truth. |
Evolution of nuclear shells with the Skyrme density dependent interaction | We present the evolution of the shell structure of nuclei in Hartree-Fock calculations using Skyrme's density-dependent effective nucleon-nucleon interaction. The role of the tensor part of the Skyrme interaction to the Hartree-Fock spin-orbit splitting in spherical spin unsaturated nuclei is reanalyzed. The contribution of a finite range tensor force to the spin-orbit splitting in closed shell nuclei is calculated. It is found that the exact matrix elements of a Gaussian and of a one-pion exchange tensor potential could be written as a product Skyrme's short range expression times a suppression factor which is almost constant for closed shell nuclei with mass number $A\ensuremath{\geqslant}48$. The suppression factor is $\ensuremath{\sim}0.15$ for the one-pion exchange potential. |
Africa's Great Lakes Region: Current Conditions in Burundi, Democratic Republic of the Congo, Rwanda, and Uganda | Africa's Great Lakes region is slowly becoming more stable after almost a decade of conflicts. The region remains vulnerable, however, since armed rebel groups are active in eastern Congo, Burundi, Rwanda and northern Uganda. This report discusses conflicts in these areas in detail, as well as U.S.-led efforts to reach peaceful resolutions. |

Low-dosage asparaginase treatment of childhood acute lymphocytic leukemia. | Asparaginase was administered to children with acute lymphocytic leukemia in dosages less than those generally used. The objectives were to determine whether toxicity of the enzyme could be reduced without loss of efficacy, and to compare weekly with twice weekly administration. In five of 11 children who received 5,000 international units (IU)/sq m twice weekly for four doses and four of ten who received 10,000 IU/sq m once weekly for two doses, examination of bone marrow showed complete remission. Although the usual asparaginase-induced toxic reactions occurred, there were no deaths due to toxic reaction and no clinical signs of pancreatic dysfunction. Toxic reactions were comparable in the once weekly and twice weekly groups. Toxicity can be decreased without loss of efficacy by using these reduced dosage schedules. |
Application of magnetic thin films for high-density data storage | Abstract The crystalline and magnetic properties of Cr-CoNi(Cr)-C layer stacks intended for longitudinal magnetic recording have been investigated. The layers were deposited on rigid disks and silicon wafers by d.c.-magnetron sputtering in inline systems. The details of the system and the process technology determine the morphology of the polycrystalline films. At low angle of incidence of the sputtered atoms textured films will result, giving rise to magnetic anisotropies and signal amplitude modulation of the disks. This modulation problem can be overcome by optimizing the sputtering conditions. The coercivity and remanence of the disks are determined by selection of alloy and thickness. Disks with more than 1300 Oe coercivity can easily be produced. |
Polarized Raman scattering of epitaxial Pb(Zr,Ti)O3 thin films in the tetragonal-phase field | In view of the difficulty in preparing single crystals, a c-axis oriented epitaxial lead zirconate titanate (PZT) film was prepared as a model system for the single-crystalline PZT. By employing an extraordinary backscattering configuration in which the relevant phonon wave vector, k, is parallel to the film/substrate interface, we have successfully isolated the E [transverse optical (TO)] symmetry phonons from A1(TO) phonons. Compared with polarized Raman spectra of the c-axis oriented PbTiO3 film, the polarized spectra of the epitaxial PZT film (with Zr/Ti=40/60) exhibited significant asymmetric line broadening with a noticeable downward shift of the mode frequencies. In addition to this, we observed a splitting of the “silent” mode into the B1-symmetry mode and the E(TO) mode using the parallel and cross polarization configurations, respectively. |
On Knowledge Economy and Knowledge People | With the development of human civilization, man has gone on the way to knowledge economy. Knowledge people refer to those who possess advanced scientific technological knowledge, humanistic qualities, and modern personality, who can play dominant role in the society of knowledge economy, and who can develop themselves continuously. This paper emphatically discusses the requirement of knowledge economy for knowledge people and the ways as to how to cultivate knowledge people. |
Imaging of Intracoronary Thrombus by Multidetector Helical Computed Tomography Angiography | An 83-year-old woman presented to the emergency department with a 2-hour history of sudden chest pain and dyspnea. An initial ECG demonstrated nonspecific ST changes, and a portable chest x-ray suggested a widened mediastinum. A thoracic multidetector helical computed tomography (CT) angiogram was obtained to assess the possibility of aortic dissection (GE LightSpeed Plus, 2.5-mm collimation with 1.25-mm reconstructions, 700-ms rotation time; 140 mL Optiray 320 nonionic iodinated contrast … |
Palladium-Catalyzed Intramolecular Carbene Insertion into C(sp3 )−H Bonds | A palladium-catalyzed carbene insertion into C(sp3)−H bonds leading to pyrrolidines was developed. The coupling reaction can be catalyzed by both Pd0 and PdII, is regioselective, and shows a broad functional group tolerance. This reaction is the first example of palladium-catalyzed C(sp3)−C(sp3) bond assembly starting from diazocarbonyl compounds. DFT calculations revealed that this direct C(sp3)−H bond functionalization reaction involves an unprecedented concerted metalation–deprotonation step. |
A light guide for keypad and a keypad for cellular phone with the light guide | A light guide for a keypad and a keypad for a portable phone using the same are provided to accomplish sufficient backlighting and power saving effects on the keypad or each key only through one or two LEDs(Light Emitting Diodes) and minimize thickness of the light guide, thereby making the portable phone slim/compact and facilitating brightness control of the backlighting. A light guide for a keypad(100) comprises the followings: a body(10) which is formed in a thin film type, is arranged between a dome sheet, installed in a PCB(Printed Circuit Board), and a base of the keypad(100), and guides or reflects a light, emitted from a light emitting unit; and plural reflectors(20) which are formed at a location of the key equipped with the keypad(100) and a rear side of the body(10) corresponding to circumference of the location, and are composed of plural reflective patterns(22) which receive light guided or reflected through the body(10) and reflect/bend the light toward the keypad(100). |
Object-oriented modelling for control synthesis and commissioning in power plants: A case study on flue gas path control | This paper presents a simulation study for the model-based synthesis and commissioning of the flue gas path control in a coal-fired power plant. Thanks to the modular model structure and the complexity tailoring capabilities offered by the adopted Object Oriented Modelling paradigm, critical manoeuvres - such as those for a fan or main fuel trip - could be tested in a timely manner and with good accuracy. Both simulation and experimental data are reported, and some discussions are carried out on the proposed approach as a general modus operandi for simulation-assisted commissioning. |
Further results on the spectral decomposition of an incidence matrix | Abstract In this paper we give some results on the spectral decomposition of a connected incidence matrix A which is a coefficient matrix of a circularization network flow problem with m + n + 2 nodes and (m + 1)(n + 1) arcs, and investigate relations between eigenvalues and the eigenvalues of the matrices AAT and MMT. It has been shown that some results obtained by the author (J. Math. Anal. Appl. 154, 1991, 13–21.) for the matrix M can be also applied to the matrix A, and then the problem can be solved in terms of eigenvectors of MMT, where MT is the transpose of M. |
The role of perceptual salience in the L2 acquisition sequence of the Arabic construct state | Perceptual salience has been proposed as an essential factor in the order in which various linguistic phenomena are acquired. This study examines its influence on the acquisition sequence of a single construction, which is the Arabic construct state. Mapping certain English constructions to the definite Arabic construct state entails restructuring head direction (a feature of high salience) and the position of the definite marker (a feature of low salience). Results from a prompted sentence completion task suggested that early English-speaking learners of Arabic were sensitive to head direction but not definiteness. Analysis of intermediate and advanced groups captured the acquisition sequence of the Arabic construct state, proceeding in two gradual phases. During the first phase, English-speaking learners restructure head direction. Only later do they adjust definiteness. |
On the Construction of Public Finance in Less-developed Areas | China takes a market-economy-oriented public financial system as the goal of its financial reform.However,the construction of public finance in the less developed areas has its own characteristics: the immature market system,the weak economic basis and the incoordination of the financial administration system,which affect the speed and quality of the construction of public finance in these areas.Meanwhile,these characteristics demand a systematic and overall consideration of all problems and a full realization of the actual needs to construct public finance in these areas so as to promote the smooth reform of China's public financial system. |

Electrical Modeling Of A Fast Charge, Inductive Store Concept For Decade | We present the system model for Physics International's modular inductive-store opening-switch DECADE concept. We discuss the system requirements and summarize the electrical issues addressed by the concept, in particular the aspects of the design which reduce the requirements on the opening switch. System performance is predicted by transient analysis simulations with two independent computer programs, and the results are compared. Results of a sensitivity analysis for selecting optimal system circuit parameters are also presented. The circuit model used in PSPICE is described in detail. Models for the transfer capacitor, opening switch, magnetically insulated transmission lines, and vacuum diode are described. The conclusions indicate the requirements on opening switch performance in order to meet DECADE radiation specifications. |

Amantadine's rocky road to acceptance. | When amantadine hydrochloride was first licensed by the Food and Drug Administration in 1966, it was specified for prophylaxis of Asian influenza. Many who have watched amantadine's tortuous path to widespread acceptance believe a basic problem lay in this initial licensing. "Soon after the approval," recalls Marvin Paulshock, PhD, associate director of clinical research, Biochemicals Department, the DuPont Company, "influenza underwent an antigen shift and we had the Hong Kong flu epidemic of 1968. The FDA decided that amantadine could not be promoted for Hong Kong influenza before its clinical effectiveness was proved. DuPont was able to show that the Hong Kong strain was inhibited by amantadine in vitro and in mice, but no clinical trials were established. We realized that we could never catch up—each time a trial would be completed, a new antigenic variant would have appeared." Instead, DuPont waited while researchers abroad and in the United States |
LOAD BALANCING IN TOTAL KNEE ARTHROPLASTY: WHAT LOADS ARE PRESENT IN THE NATIVE KNEE? | IntroductionA correct balancing of the knee following TKA surgery is believed to minimize instability and improve patient satisfaction. In that respect, trial components containing force sensors can be used. These force sensors provide insight in the medial/lateral force ratio as well as absolute contact forces. Although this method finds clinical application already, the target values for both the force magnitude and ratio under surgical conditions remain uncertain.MethodsA total of eight non-arthritic cadaveric knees have been tested mimicking surgical conditions. Therefore, the specimens are mounted in a custom knee simulator (Verstraete et al., 2015). This simulator allows to test full lower limb specimens, providing kinematic freedom throughout the range of motion. Knee flexion is obtained by lifting the femur (thigh pull). Knee kinematics are simultaneously recorded by means of a navigation system and based on the mechanical axis of the femur and tibia.In addition, the load transferred through the m... |

Modelling interest rate volatility: Regime switches and level links | Modelling Interest Rate Volatility: Regime Switches and Level Links.— This paper presents a model encompassing the Markov switching model and the model based on a volatility-level link. This encompassing model allows to test these competing classes of volatility models against each other. If is found that both classes capture essential but different features of the interest rate volatility process. A volatility model incorporating both features, i.e., regime switches and level links, clearly outperforms both alternatives. The consequences of this finding, both for volatility prediction and for the selection of the more appropriate theoretical (continuous time) interest rate model, are discussed. |
Developmental arsenic exposure is associated with sex differences in the epigenetic regulation of stress genes in the adult mouse frontal cortex | Abstract Previously, we reported sex-dependent changes to global histone modifications and impairment of executive function in adult mice exposed to moderate levels of arsenic during early development. The present study investigated the effects of developmental arsenic exposure (DAE) on gene specific histone 3 lysine 9 acetylation (H3K9ac) and tri-methylation (H3K9me3) in the frontal cortex of male and female adult C57BL/6J mice. Dams were exposed to 50ppb arsenic in drinking water prior to and throughout gestation, and until pup weaning; once weened, the pups were given tap water ( |
Some measure algebras on the integers. | "concrete" in the sense that the elements of the algebra are sets, the notion of an integrable function is available and the normed vector space of integrable functions can be shown to be isometrically isomorphic to an ordinary L1 space. If a function / is integrable, it is shown that its integral is given by where /* is a suitably chosen function differing from / only on a set of density 0. This construction differs from others (several are described by Kubilius in his book on probabilistic methods in number theory), because usually countable additivity is sacrificed, whereas here the meaning of countable join has been altered. The work was motivated by a desire to prove Theorems 3 and 4 which concern an application to sequences (mod 1). We also include some remarks concerning the possibility of constructing probabilistically independent measure algebras. Furthermore by means of the Cantor expansion of a number we construct an algebra which contains all periodic sequences. |
Characterization and properties of micro- and nanowires of controlled size, composition, and geometry fabricated by electrodeposition and ion-track technology | The combination of electrodeposition and polymeric templates created by heavy-ion irradiation followed by chemical track etching provides a large variety of poly- and single-crystalline nanowires of controlled size, geometry, composition, and surface morphology. Recent results obtained by our group on the fabrication, characterization and size-dependent properties of nanowires synthesized by this technique are reviewed, including investigations on electrical resistivity, surface plasmon resonances, and thermal instability. |
Endoscopic Correction of Vesicoureteral Reflux Secondary to Posterior Urethral Valves | AbstractPurpose: We review our experience with children with high grade vesicoureteral reflux secondary to posterior urethral valves treated endoscopically with subureteral polytetrafluoroethylene (Teflon) injection.Materials and Methods: Between 1985 and 1994, 54 infants and children were diagnosed with posterior urethral valves of whom 38 (70 percent) had vesicoureteral reflux. In 9 patients reflux resolved after valve ablation. Seven patients underwent nephroureterectomy for nonfunctioning kidneys and in 2 reflux was treated with continuous chemoprophylaxis. The remaining 20 patients underwent an antireflux procedure, including reimplantation of the ureters in 5 and subureteral polytetrafluoroethylene injection in 15. Of the 15 patients who underwent injection 6 had unilateral and 9 had bilateral vesicoureteral reflux. According to the international classification reflux was grade IV in 6 ureters and grade V in 18. Patient age at injection ranged from 8 months to 6 years (mean 2.2 years).Results: Reflu... |
MODEL DECOMPOSITION IN A SERVOCOMPENSATOR PROBLEM | ABSTRACT The purpose of this work is to analyse a method of model decomposition in a servo-compensator problem with plant having slow and fast modes. This decomposition is based on the evaluation (in frequency-domain) of the “small” value of the parameter in equation 1 x ˙ 1 = A 11 x 1 + A 12 x 2 + B 1 u μ x ˙ 2 = A 21 x 1 + A 22 x 2 + B 2 u The value of the parameter μ which may be considered as “small” depends on plant dynamical properties, noise signal, type and adjustments of commercial PID controllers. |
Adaptive prefilter for bit-rate improvement in video compression | It is very important to control the bit-rate for video communication under a limited capacity of communication channel like wireless communication system because of large amout of data. In this paper, we propose a new adaptive pre-filter to improve the bit-rate in video compression, which preserves visually significant portion of the original image and smooth only insignificant portion actively. We focus on the differential signals between the original image and its filtered one and control the degree of smoothing by considering the power of local differential signals to produce various kinds of intermediate images betwwen both images. We conducted some computer simulations to check the performance of our scheme for the standard MPEG-4 video compression algorithm. Consequently, we could achieve further improvement of compression ratio while improving visual image quality than a conventional scheme. |

The objective of the article is to examine the degree of functionality and effi ciency of the current status to ensure meaningful regulation on food advertising aimed at children in the Czech Republic as one of the possible causes of rising obesity and overweight. To better understand the relations between all the institutions involved in regulatory and self-regulatory process in the Czech Republic, we have developed model of these relations. We also studied the impact of European institutions that infl uence the Czech model. In conclusion, we propose changes that could in the short term contribute to the effectiveness of the current system. |
Digitopolis meets encalming technology | Digitopolis (the city-like ecosystem of the computer industry) has to keep expanding its installed base or it will go into a major depression. To stay vibrant, Digitopolis requires a rapidly expanding market for computerized gadgets. Given the ever-shorter life cycles for hi-tech products, this is becoming increasingly difficult-unless the units shipped or profit margins go up dramatically. The answer: build network appliances, automobiles, telephones, games, and wallet computers as fast as consumers will adopt them. Thus, the next big thing will be gadgets. The author looks at two scenarios of what might happen in the industry's network appliance segment. In the first scenario, the network appliance is all user interface. In the second, the network appliance is invisible; it disappears. |
