He had a history of surgery for hepatic hydatidosis; diagnosis was made preoperatively with the help of conventional x-ray studies, pelvic sonography, and CT scanning. Treatment consisted of removal of the cyst. |
Genetic Algorithms for Extension Search in Default Logic | A default theory can be characterized by its sets of plausible conclusions, called its extensions. But, due to the theoretical complexity of Default Logic (Sigma_2p-complete), the problem of finding such an extension is very difficult if one wants to deal with non trivial knowledge bases. Based on the principle of natural selection, Genetic Algorithms have been quite successfully applied to combinatorial problems and seem useful for problems with huge search spaces and when no tractable algorithm is available. The purpose of this paper is to show that techniques issued from Genetic Algorithms can be used in order to build an efficient default reasoning system. After providing a formal description of the components required for an extension search based on Genetic Algorithms principles, we exhibit some experimental results. |
Laser-induced electron transfer desorption/ionization of metal complexes on TiO2films | Thin titanium dioxide (TiO2) films were studied as ion emitters for the laser-induced electron transfer desorption/ionization (LETDI) of metal complexes with organic reagents. The TiO2 films (350 nm thick) were deposited on the silicon substrates by e-beam evaporation of TiO2 powder. Copper complex with phthalocyanine, rhenium complex with thiocarbanilide and platinum complex with 8-quinolinethiol were studied as the test analytes. Reflectron time-of- flight mass spectrometer with the rotating ball interface was used for analysis. The analytes were applied on the surface of TiO2 film using an electrospray deposition. All tested compounds are detected as the radical molecular ions with no fragmentation. It is found, that TiO2 films are very stable and show good sensitivity in examined range of the analyte concentrations. The limits of detection of studied complexes were at the subfemtomole range, and the relative standard deviation was less than 10%. |
A Neural Network Approach on Analyzing and Reducing Signalized Intersection Crashes | In this study, a back propagation artificial neural network model utilizing characteristics of urban signalized intersections for occurrence prediction of intersection - related traffic crashes, along with its application for crash reduction, are proposed. The 1,593 traffic crashes reported at 62 signalized intersections in Taichung city, Taiwan during year 2000 - 2001 were analyzed. These intersections were decomposed into 636 approaching direction combinations (ADCs). Characteristics, as well as the number of crashes, corresponding to each ADC were investigated. A back propagation artificial neural network (ANN) model was then generated. It was found that the ANN model exhibited great prediction ability with 0.992 correlation coefficient, and 3.38E- 06 mean square error. With the ANN model, a proposed decision-making scheme for intersection rehabilitation was suggested. Case study indicated that the suggested scheme could serve well as a referable tool. |

The Design of a 'Motivating' Intelligent Assessment System | This paper intends to present the design of an intelligent assessment system, which attempts to assess the student in arithmetic word problem solving. During assessment, the system keeps track of the aptitudes, which the student shows, concerning the answers he/she gives to special types of problems and in the same time it observes aspects of the student's motivational state. More precisely, motivation aspects deal with a) the effort the student shows in solving the different types of problems and b) with the independency and the confidence that characterize his/her behaviour. The system tries to adapt itself according to the above information, in order to motivate the student, offering her the appropriate help and the possibility to follow an individualized way through the objective items of the assessment. |
Mathematical theory of the stationary propagation velocity of a fine-scale turbulent flame | A boundary-value problem in the theory of propagation of a fine-scale turbulent flame is investigated, taking into account the influence of temperature and concentration pulsations on the magnitude of the heat liberation rate. In contrast to [1], the case when a second-order reaction proceeds in the flame is examined in detail. Conditions are found for the existence of a turbulent flame; the structure of the flame front is studied by a computational method. A change in the progress of the reaction is disclosed near the propagation limits. |
Maxwell–Stefan theory for macropore molecular–diffusion-controlled fixed-bed adsorption | Abstract Maxwell–Stefan theory was applied for simulating a multicomponent, macropore molecular–diffusion-controlled fixed-bed adsorption process. Simulations were also made based on the conventional Fick formulation. By comparing the simulation results with experimentally measured column dynamics for the adsorption of O 2 –N 2 –He mixture on 5A zeolite, it was found that both sets of simulations agree with each other and are in good agreement with the experimentally observed behaviour. |

Evaluation of the Influence of Ambient Temperature on the Performance of the Trans-Amadi Gas Turbine Plant | This paper examines the effects of ambient temperature on the Trans-Amadi gas turbine power station Phase II. The investigation took thirteen (13) months (January 2012 to January 2013) during which plant data were monitored and operational Logsheets like turbine logsheets, plant—auxiliaries’ logsheets and generator logsheets were studied. The gas turbine (GT) that was under investigation was GT-2: MS5001 Nuovopignone with designed installed capacity of 25.0 Megawatts (MW). The result of the study shows that a 1℃ rise of the ambient temperature is responsible for the following: 0% - 0.12% decrease in the power output, 0% - 0.12% increase in the power differential, 0% - 1.17% decrease in the thermal efficiency, 0% - 27.18% increase in the heat rate and 0% - 3.57% increase in the specific fuel consumption. An ambient temperature of 30℃ is found to yield minimal fuel consumption. |
Revealing Extraordinary Intrinsic Tensile Plasticity in Gradient Nano-Grained Copper | Nano-grained (NG) metals are believed to be strong but intrinsically brittle: Free-standing NG metals usually exhibit a tensile uniform elongation of a few percent. When a NG copper film is confined by a coarse-grained (CG) copper substrate with a gradient grain-size transition, tensile plasticity can be achieved in the NG film where strain localization is suppressed. The gradient NG film exhibits a 10 times higher yield strength and a tensile plasticity comparable to that of the CG substrate and can sustain a tensile true strain exceeding 100% without cracking. A mechanically driven grain boundary migration process with a substantial concomitant grain growth dominates plastic deformation of the gradient NG structure. The extraordinary intrinsic plasticity of gradient NG structures offers their potential for use as advanced coatings of bulk materials. |
Using EBG to Improve Antenna Efficiency in Proximity to the Human Body | This paper presents a 2.45 GHz patch antenna over an EBG substrate with the objective of higher radiation efficiency and compact operation in close proximity to a lossy medium, both of which are critical for body worn antennas. To achieve compact size, several sizes of EBG are included and the individual antenna efficiency and radiation pattern are studied. From these results, the EBG substrate demonstrates great improvement of the antenna efficiency but its size has a considerable effect on efficiency when the antenna is used in close proximity to the human body. |
Obstructive Sleep Apnea Syndrome: An Emerging Risk Factor for Dementia. | Epidemiological studies have suggested that obstructive sleep apnea syndrome (OSAS) may increase the risk of developing cognitive impairment. In patients with Alzheimer's disease (AD), the prevalence of OSAS is much higher than that expected in cognitively healthy subjects. A deeper knowledge of the pathophysiological link between OSAS and AD and the demonstration that OSAS may directly influence the development of cognitive alterations, would increase prevention and treatment strategies for AD patients. In this article, we discuss the evidence of the association between OSAS and dementia. Moreover, we present data about the functional and anatomic cerebral changes induced by OSAS and the possible effects on cognitive activities and on AD pathogenesis. The possibility to positively influence cognitive impairment by OSAS treatment will be also discussed. |
Numerical Simulation of Wind Velocity History on the Basis of Orthogonal Inverse Wavelet Transform | Wind load is one of the major even decisive factors to large-structure for which the time domain analysis of wind-induced dynamic response is required.The problem how to input the wind load is therefore to be solved first.According to the idea of multi-resolution analysis and orthonormal wavelets,relationship between wavelet coefficients and PSD(power spectral density) function is deduced,then the wavelet coefficients on each and every scale are obtained from the given PSD function.As a result,the inverse wavelet transform is applied to generating stationary wind velocity history through the given wavelet coefficients.In this way the L-P wavelet is applied to simulating the pulsate wind velocity history at a certain point,which conforms to Davenport power spectral density.A numerical example shows that the simulated PSD is consistent with the prescribed one and the method is valid. |
Incisional hernia around the suprapubic catheter: an unusual complication | Hernia through the suprapubic catheterization (SPC) site is rare. Attention is required for such hernias as they get obstructed due to the narrow neck. We report this rare presentation in an elderly gentleman with obstructed incisional hernia through the SPC site, which was reduced and subsequently had a successful mesh repair. |
Crystal fields and Kondo effect: Magnetic susceptibility of Cerium ions in axial crystal fields | Abstract The thermodynamic Bethe ansatz equations of the Coqblin-Schrieffer model have been solved numerically. The full N = 6 (J = 5/2) degeneracy of the Hund’s rule ionic ground state of Ce is taken into account. Results for the temperature dependent magnetic susceptibility parallel and perpendicular to the crystal axis are presented. The deviations, due to the Kondo effect, to the non-interacting ion results are pointed out. |

Survey and Analysis of Kindergarten Teachers' Curriculum Awareness | To gain insights into the development of kindergarten teachers' curriculum awareness and effectively guide their teaching behaviors,this survey starts with such six dimensions as the curriculum awareness of subjectivity,goal,generating,resources,evaluation,and environment by selfproducing questionnaires.The findings indicate that teachers differ in dimensions,but generally they are relatively conscious of the curriculum,and that their awareness is influenced by the factors of ages and educational backgrounds,and that differences exist between awareness and performance,and that the rooted notion of teaching awareness in kindergarten teachers' mind has a negative impact on the promoting of their curriculum awareness. |
Repeated automatic visual field screening in a cohort study. | During 1977 and 1978 automatic visual field screening was performed in 1511 persons born 1907-1921 and taking part in a population study. Three years later automatic visual field screening was repeated in 2565 eyes of 1293 persons. "Irrelevant" defects were common and had a limited repeatability. "Relevant" defects were easily detected at the first and reproduced at the second survey. From a clinical point of view, the yield of the visual field screening at the second survey was restricted. We concluded that repeated visual field screening by automatic perimetry is quite feasible but has little reward. |
A Study on an Effective Group Management Scheme for Secure Multicast in MIPv6 | While a lot of important information is being sent and received on the Internet, the information could be exposed to many threats, and the more the multicast service is various and generalized, the more the service range is widened. When a new member joins in or leaves from the multicast group, the group key, which the existing member used, should be newly updated. The existing method had a problem that the performance was depreciated by the key exchanging. This paper proposes the effective group management mechanism for a secure transmission of the multicast data on the multicast group. |
[Massive digestive hemorrhage caused by arterial malformation of the jejunum. Diagnostic value of emergency arteriography]. | A case of massive digestive bleeding due to an arterial abnormality of the jejunal wall is reported. Its interest is twofold: a) After a complete endoscopic and operative examination of the GI tract proved negative, an emergency superior mesenteric angiography was the only investigation which allowed to recognize the site and mechanism of the bleeding; b) from a nosologic point of view, the clinico-pathological picture was entirely similar to that of "Dieulafoy's erosion", a syndrome which has been only described, up to now, in the gastric mucosa. |
Bound on extended $f$-divergences for a variety of classes | The concept of f-divergences was introduced by Csiszar in 1963 as measures of the ’hardness’ of a testing problem depending on a convex real valued function f on the interval [0,∞). The choice of this parameter f can be adjusted so as to match the needs for specific applications. The definition and some of the most basic properties of f-divergences are given and five classes of f-divergences are presented. Ostrowski’s inequality and a trapezoid inequality are utilised in order to prove bounds for an extension of the set of f-divergences. All five classes of f-divergences are used in order to investigate limitations and strengths of the inequalities derived. |
NMR Studies of Drugs. Applications of Lanthanide Shift Reagents to Afloqualone, an Axially Chiral Quinazolinone. | Abstract The skeletal muscle relaxant, aflogualone, 1, has been studied by 1H NMR in CDC13 at 60 and 300 MHz in the presence of added chiral [Eu(HFC)3] or achiral [Eu(FOD)3] lanthanide shift reagents (LSR). With Eu(HFC)3, significant enantiomeric shift differences, ΔΔδ, can be induced for most of the nuclei of 1, with near-baseline resolution obtainable for the H-5 signals of each enantiomer, indicating excellent analytical potential for direct determination of enantiomeric excess of samples of 1. Observation of ΔΔδ directly confirms hindered rotation about the bond between N (3) and the 2-methylphenyl group, i.e., the N (sp2) - C(sp2) bond, leading to axial chirality in 1 with slow rotation on the NMR timescale. Assignments are supported by 2D COSY spectra at 300 MHz. Relative lanthanide-induced shift magnitudes for the protons of 1 are compared. |
Critical size of crack propagation from residual void in micro via in printed wiring boards | The micro-via was fabricated with diameter of 200 to 400μm, inner hole plate thickness of 18μm, hole land thickness of 18 to 20μm, and solder resist thickness of 13μm on hole land. We investigated that the size of residual void increased as that of micro-via increased; also, dominance of micro-via cracking was observed when temperature was applied at 100°C for 2 hours. When the printed circuit board containing void is heated, the micro-via cracking is accelerated in the micro-via with residual void larger than 50% of via diameter. This is significantly verified by calculation of coefficient for stress concentration in the study. |
DIAL-A-BUS-SERVICE : A CHANGE TO INDIVIDUAL PUBLIC TRANSPORT | Dial-a-Bus is a new form of public transport without any adherence to fixed timetables, routes or bus stops. Passengers are transported from door-to-door. The core activity in Dial-a-Bus operations is the dispatching of travel requests in a dispatch center. Nowadays modern information and communication technologies are available, to organize the operation of Dial-a-Bus in an optimal way. Volkswagen has initiated several practical tests under real life conditions. The results and experiences are: The Dial-a-Bus concept works and can be economically viable. The computer aided dispatching system improves the operation efficiently. The Dial-a-Bus concept is very well looked upon by the public with more and more interest for further applications. Dial-a-Bus seems to be an intelligent system to meet requirements of public transport |

Acidification of antisense NHE-1 gene transfection on gastric cancer cell line SGC-7901 and its significance | Objective To study the effects of the transefection of antisense human Na + -H + exchanger 1 (NHE-1) on the pHi of SGC-7901 and its potential role in the gene therapy for cancers. Methods Eukaryotic expression vector pcDNA3.1 encoding antisense NHE-1 was constructed with recombinant DNA technique and transfected into SGC-7901 with liposome DOTAP. The pHi changes of the transfected cells and untransfected cells was detected with a fluorescent probe, BCECF. The proliferation and apoptosis of the cells was studied with flow cytometry. Results Antisense NHE-1 gene transfection induced the acidification, decreased proliferation, and elevated apoptosis of SGC-7901 cells. Conclusion The results suggest that NHE-1 gene plays an important role in the regulation of pHi, reproduction and apoptosis of tumor cells. Inhibiting the over-expression and activity of NHE-1 may be of important clinical value. |

Molecular interpretations are discussed and related to previous studies of cholesterol/dioleoylphosphatidylcholine and of cholesterol-rich biological membranes. |
Essay Examinations and Objective Tests in United States History in the Junior High School | An examination of the literature relating to testing in the social sciences indicates the widespread popularity of objective tests. This popularity is particularly shown in the literature relating to testing in United States history. In recent years, however, some educators have attacked the objective, or new-type, tests on the ground that they do not measure understanding. These critics have insisted that objective tests are informational in character and that such tests measure only memory and recall. If this criticism is true, objective tests cannot be justified in United States history for, obviously, the main objectives of instruction in this subject are understanding and comprehension rather than memory and recall. |

Neoplastic transformation of oral lichen: case report and review of the literature. | Aim of the present investigation was to analyse the possible malignant transformation of oral lichen planus to carcinoma, especially in the atrophic erosive forms and those displaying plaques involving the top of the tongue. A review has been made of the literature, from 1986 to the present day. This search outlines the relationship between oral lichen planus, hepatitis C virus infection, Epstein-Barr virus infection and the importance of periodic follow-up in all patients with oral lichen planus. The case is described of malignant transformation of oral lichen planus to oral cancer in a female presenting asymptomatic hepatitis C virus infection. The clinical history confirms the most important aspects of the relationship between oral lichen planus and oral cancer. Oral lichen planus should be considered as a precancerous lesion, particularly in patients presenting hepatitis C virus infection, requiring follow-up, at close intervals, starting from 3 months after diagnosis. |
Thymidine phosphorylase (platelet-derived endothelial cell growth factor) as a target for capecitabine: from biology to the bedside. | Thymidine phosphorylase (TP), also known as platelet derived endothelial cell growth factor (PD-ECGF), is an enzyme involved in thymidine synthesis and degradation and exerts an angiogenic activity, whereas N4 pentyloxy-carbonyl- 5'-deoxy-5-fluorocytidine, commonly called capecitabine (CAP), is a TP-activated oral fluorpyrimidine, which generates 5-fluorouracil (5-FU) within tumours. In addition to its classic antitumour activity, recent studies suggest that CAP may act as an antiangiogenetic molecule. Assessment of tumour microvessel density as expressed by endothelial cell TP positivity may identify the most vascularized and hence CAP-sensitive tumours. This review summarizes: (i) the biochemical and tissue expression of TP; (ii) the pharmacological profile of CAP as an anti-cancer compound and the central role of TP in its activation; (iii) the potential antiangiogenetic role of TP-activated CAP in tumours. |

Digital PIV: A Challenge for Feature Based Tracking | Motion tracking is an important step of the analysis of flow image sequences. However, Particle Image Velocimetry (PIV) techniques rarely use tracking methods developed in computer vision, they usually work with FFT and correlation based methods. Two major types of motion estimation algorithms exist: the optical flow and the feature based ones. Promising results have been obtained by applying optical flow techniques to PIV. The applicability of feature based tracking algorithms to PIV images is examined in this article. Two feature based and one optical flow based tracking algorithms are considered. Flow measurement and visualisation results for standard PIV sequences are presented. |
A Heuristic for Commodity Procurement in the Presence of Price Discounting | A liquid developer which includes an insulating liquid, and toner fine particles containing a coloring agent and a toner resin. In the liquid developer, its electric capacitance does not significantly vary in an electric circuit where an electrical double-layer capacitor and an electronic resistance corresponding to a velocity of an electron exchange during an electrode reaction are connected in parallel, and a resistance corresponding to an electric conductivity of the insulating liquid is connected in series. The coloring agent has a coating layer so as to maintain distances between the toner fine particles. The insulating liquid has a viscosity of 0.5 mPa.s to 1000 mPa.s, a specific resistance of 1x1012 Omegacm or more, and a surface tension of 30 dyn/cm or less, and may be a nonvolatile liquid having a boiling point of 100° C. or higher. |
Thermally induced phase transitions in tridymite: an infrared spectroscopy study | The temperature dependence of the infrared active modes of meteoritic and synthetic tridymite have been investigated between 23 K and 1073 K in IR absorption and IR emission experiments. At room temperature both tridymite samples consist of a mixture of low temperature forms, in different proportions, due to the grinding. The sequence of phase transitions in Steinbach tridymite deduced from the IR data agrees well with recent X-ray and calorimetry studies using identical samples (Cellai et al. 1994). The previously suspected structural phase transition P6322⇔P63/mmc is confirmed by the disappearance of the 470 cm-1 mode and a temperature anomaly of the spectral shift of the 790 cm-1 mode. Changes in the infrared spectra of synthetic tridymite give a different sequence of phase transitions from those of the meteoritic sample, consistent with the structural phase transitions observed in a 29Si MAS NMR investigation using the same sample (Xiao et al. 1993). |
First enantiospecific syntheses of crotepoxide and iso-crotepoxide from (-)-quinic acid | Abstract The optically active crotepoxide 1 and iso -crotepoxide 2 have been constructed from quinic acid involving a singlet oxygen photooxygentation as the key step. |
Microwave-assisted fabrication of superhydrophobic surfaces on aluminium foil and the anti-corrosion properties | Superhydrophobic surface on aluminium (Al) substrate was successfully fabricated via a microwave-assisted process by immersing the clean pure Al substrate into the mixed solution of Zn(NO3)2 and hexamethylenetetramine, and modified with stearic acid (STA). Surface morphology and composition were characterised by using scanning electron microscopy (SEM), X-ray diffraction and X-ray photoelectron spectroscopy. The wettability and the corrosion resistance properties of the surface modified with STA were characterised. The results show that the sample had a high water contact angle of about 155°. It has good anti-corrosion for alkali and 3.5 wt% sodium chloride solution. From SEM images, it was found that abundant regular micronano sheets distributed on the surface at random and there are large amount of interspace amount the sheets. The special structure and the low surface energy make the Al foil have superhydrophobic surfaces. |

Low Levels of Nerve Growth Factor in Cerebrospinal Fluid of Children With Rett Syndrome | A role for neurotrophic factors has been postulated in some human neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. The known developmental effects of these substances suggested that, in some neurologic diseases affecting children, neurotrophic factors might be inadequate. Using a sensitive, two-site enzyme-linked immunoassay, we examined the content of nerve growth factor in the cerebrospinal fluid of 11 children with Rett syndrome and of 24 control patients with various neurologic diagnoses or suffering from other diseases. Nerve growth factor levels were significantly lower in the cerebrospinal fluid of the patients with Rett syndrome than in control patients. The lower level of cerebrospinal fluid nerve growth factor in Rett syndrome suggests that lack of nerve growth factor may be involved in the pathogenesis of this disease or reflect the underlying brain damage present. (J Child Neurol 1996;11:296-300). |
Flags as a New Assessment of Mental Health Status | Mental health is examined from a social-psychological perspective based on years of clinical experience in USA and some Arab countries. Three hundred and fifty-two participated to examine the validity and the reliability of this new instrument. Eleven social-psychological variables, integrated with five central emotions, make up the FLAGS assessment, which proved to have strength and dependability. |
Concentrations of Organic Acids in the Urine of Healthy Newborn Children | Urine concentrations of organic acids were determined by a gas chromatographic technique in healthy, full-term neonates at the ages of 2 and 5 days. Significant reductions in the interindividual variation were obtained by relating the levels of organic acids to urine creatinine concentration or osmolality. Citrate was the predominant organic anion found. Urine concentrations of fumarate, 3-hydroxy-3-methylglutarate, adipate, and suberate decreased during the first week of life, and their concentrations were significantly intercorrelated. It is suggested that these findings reflect the predominantly fat-utilising, hyperketonaemic state during the first days of life. The urine concentrations of the aromatic end-products, p-hydroxyphenylacetate and hippurate, increased during the first week of life, probably as an effect of dietary factors. It is concluded that analysis of intermediary organic acids in urine could be of value in the assessment of the metabolic state in neonates. |
The Nature of Hypnotic Analgesia and Placebo Response to Experimental Pain | The effects of hypnotically induced analgesia and placebo response to “a powerful analgesic drug” were investigated.

FPGA based Digital Pulse Width Modulator with Time Resolution under 2 ns | This work proposes a new DPWM architecture that takes advantage of FPGA's advanced characteristics, especially the DLLs (Delay-Locked Loop) present in almost every FPGA. The proposed DPWM combines a synchronous (counter-based) block with an asynchronous block for increased resolution without unnecessarily increasing the clock frequency. The experimental results show an implementation in a low cost FPGA (Xilinx Spartan-3) that uses an external 32 MHz clock for a final time resolution under 2 ns. |

Teaching Internships and the Learning Community | Recent education reforms have meant that many universities are re-examining, refining and implementing teacher education courses that are aligned with the curricular, pedagogical and organizational reforms influenced by past educational research. At the same time an increased emphasis has been on the development of university school partnerships leading to improved relations between schools and universities through the introduction of initiatives such as an internship program. Since the 1990's various Australian professional and government groups have recognised the importance of internships in the preparation of teachers (Australian Council of Deans, 1998; Queensland Board of Teacher, 1999). However there is considerable confusion over the meaning of an internship. |
The structure of oxygen-induced reconstruction on Cu{100}-c(2×2)-Pt surface alloy: the Pt/Cu{100}-(2×2)-O | Abstract Adsorption of 0.25 ML oxygen on the Cu{1 0 0}-c(2 × 2)–Pt surface alloy followed by a brief thermal activation to 500 K and recooling to room temperature leads to the formation of a surface structure with a p(2 × 2) periodicity. The structure of this Pt/Cu{1 0 0}-(2 × 2)–O has been determined by quantitative low energy electron diffraction (LEED) calculations using the symmetrised automated tensor LEED (SATLEED) program. The results of the calculations suggest that simple p(2 × 2) overlayers can be ruled out in favour of an oxygen-induced surface reconstruction. The favoured model (Pendry R -factor=0.23) consists of a mixed c(2 × 2) CuPt underlayer below a reconstructed Cu{1 0 0} outermost layer with oxygen atoms occupying a slightly displaced fourfold hollow sites above second layer Pt atoms relative to the original unreconstructed surface. |
Developing emerging leaders in the library profession : program content, self-efficacy and leadership | This thesis used experimental and qualitative methods to determine that a typical, formal library leadership development intervention significantly enhanced the leadership self-efficacy of participants. The investigation also ascertained what program content and attributes affected leadership self-efficacy and how these elements either deterred or enhanced leadership self-efficacy development. Self-efficacy is critical to leadership emergence and effectiveness. Leadership succession has been identified as an issue in the library profession and society as a whole. The research confirmed that leadership development interventions with appropriate structure and content can be an effective mechanism to foster the emergence of leaders. |
Effect of Nitrite on Anaerobic Metabolism of Candidatus Accumulibacter Phosphates | In order to investigate the metabolism of Candidatus Accumulibacter Phosphates(a well-known phosphate accumulating organism) and its affecting factors,anaerobic-aerobic SBR reactor was performed to incubate polyphosphate accumulating organism(PAO) using synthetical sewage,and the content of PAOs reached more than 80%.Based on the enriched culture,several batch experiments were taken.The results indicated that when acetate and nitrite were both in the reactor(in 60min),with the increasing of the initial nitrite,Accumulibacter released much more PO3-4-P,whereas the acetate uptake rate and the amount of accumulated PHA decreased.After 60min,the concentration of phosphate,nitrate and PHA were all degressive,suggesting that denitrifying phosphorus removal were occurred.The results suggested that there were denitrifying phosphorus organisms.Besides,there were a part of PAOs which could be poisoned by nitrite in this system. |
Insights on speciation patterns in the genus Iberochondrostoma (Cyprinidae): evidence from mitochondrial and nuclear data. | In this paper, the patterns of cladogenesis in the cyprinid fish genus Iberochondrostoma were analysed using a mitochondrial (cytochrome b) and a nuclear (beta-actin) gene fragment. The two genes yielded discordant results. While the cytochrome b gene yielded a fully dichotomous tree, where all species of the genus are monophyletic, the much slower beta-actin gene yielded star-like relationships. However, when information from both genes was considered together, the data suggested the persistence of a very large central unit from which at least two peripheral clades arose at different times. This pattern which is akin to peripatric speciation was shown to be compatible with the paleogeographical information available. It is suggested that combining the techniques of phylogeny and phylogeography and the use of multiple markers varying in their rate of evolution may enrich our understanding of speciation and evolution of clades beyond species level. |
SELENIUM DETERMINATION IN SOIL AND PLANT MATERIALS | Selenium (Se) was determined in soil and plant samples after wet digestion with HNO3 and HClO4. The method included the usual steps, namely, the reduction of Se, complexing Se with 2,3-diaminonaphthalene, and the extraction of the piazselenol in cyclohexane followed by fluorometric measurements. The most important step, the stabilization of selenium at the oxidative state Se+4, was achieved by reducing Se+6 to Se+4 with 2 ml of 1 N HCl while the system was kept in a boiling water bath. For best results and adequate control of interfering ferric ions, the system was adjusted to pH 1.8, and a stabilizing agent consisting of 10% hydroxylamine hydrochloride in a 0.04 M EDTA solution was used. Fluorescence measurements obtained for soil samples gave average coefficients of variation and recovery percentages of 3.35 and 97.4, respectively. For radioactivity counts made on cyclohexane extracts, the coefficients of variation and the recovery percentages were 2.31 and 93.1, respectively. Similar results were obtai... |
Implementation of FWLR for process reliability monitoring | In Chartered, process reliability monitoring (PRM) begins after a new technology is qualified, aims at ensuring specific reliability goals are met and detecting reliability degradation due to process drift/changes and in-line issues. PRM data is provided to customer on a regular basis. Traditional PRM programs (package level stress) are expensive and time consuming, while very short test time of FWLR (Fast Wafer Level Reliability) offers a practical technique of providing quick intrinsic reliability information to process engineers. FWLR is defined as highly accelerated stress, specific to a particular failure mechanism, to measure rate of degradation of material. When correlation with traditional more moderate stress is established, FWLR can also be used for lifetime extrapolation purpose. This paper describes the implementation of FWLR to monitor intrinsic process reliability performance. |
Liaison has amplifying optical fibers. | the transmission line sections (2) of a link include passive sections (16) transmitting the signal without compensating for its natural weakening and occupying between 15% and 65% of the length (14) of these sections. They further include active sections (18, 20) amplifying this signal. The invention applies in particular to the achievement of intercontinental links. |
Effects of Temperature and Humidity Treatment Conditions on the Interfacial Adhesion Energy between the Electroless-Plated Ni and Polyimide | The effect of temperature/humidity treatment conditions on the interfacial adhesion energy between an electroless-plated Ni film and a polyimide substrate was evaluated by using a 180° peel test. The measured peel strength values decrease from 506.1 ±18.6 to 231.9 ±33.3 J/m2 due to the temperature/humidity treatment at 85 °C/85% relative humidity for 1000 h. X-ray photoelectron spectroscopy analysis of the peeled surfaces indicates that peeling occurs cohesively inside of the polyimide; this is related to both the decrease in the interfacial adhesion energy and the polyimide degradation when small quantities of the remaining alkali ions react with the polyimide's functional groups during the temperature/humidity treatment. |
KEYWORD EXTRACTION STRATEGY FOR ITEM BANKS TEXT CATEGORIZATION | We proposed a feature selection approach, Patterned Keyword in Phrase (PKIP), to text categorization for item banks. The item bank is a collection of textual question items that are short sentences. Each sentence does not contain enough relevant words for directly categorizing by the traditional approaches such as “bag-of-words.” Therefore, PKIP was designed to categorize such question item using only available keywords and their patterns. PKIP identifies the appropriate keywords by computing the weight of all words. In this paper, two keyword selection strategies are suggested to ensure the categorization accuracy of PKIP. PKIP was implemented and tested with the item bank of Thai high primary mathematics questions. The test results have proved that PKIP is able to categorize the question items correctly and the two keyword selection strategies can extract the very informative keywords. |

The current system associated with the boundary of plasma bubbles | The current system associated with the boundary of plasma bubbles in the Earth's magnetotail has been studied by employing Cluster multipoint observations. We have investigated the currents in both the dipolarization front (DF, leading edge of the plasma bubble) and the trailing edge of the plasma bubble. The distribution of currents at the edge indicates that there is a current circuit in the boundary of a plasma bubble. The field-aligned currents in the trailing edge of the plasma bubble are flowing toward the ionosphere (downward) on the dawnside and away from the ionosphere (upward) on the duskside, in the same sense as region-1 current. Together with previous studies of the current distributions in the DF and magnetic dip region, we have obtained a more complete picture of the current system surrounding the boundary of plasma bubble. This current system is very similar to the substorm current wedge predicted by MHD simulation models but with much smaller scale. |

Integration of single-stage SPV generation to grid using admittance based LMS technique | In this paper, an integration of single-stage solar photovoltaic (SPV) generation to three-phase AC grid is proposed using admittance based LMS (Least Mean Square) adaptive control approach. The main focus of the system is to supply active power to the grid as well as loads at PCC and also mitigate several power quality issues like current harmonics distortion, reactive power and load unbalancing. A simple LMS based admittance control with P&O (Perturb and Observe) based MPPT (Maximum Power Point Tracking) is used for achieving efficient system. The proposed control is easy to implement and has a fast response. The performance of the system is simulated in MATLAB environment under variable solar irradiance, balanced and unbalanced load (linear and nonlinear) conditions in both PFC and ZVR modes. |
Signal circuit and cold junction compensation of fiber-optic thermocouple sensor | A fiber-optic thermocouple sensor is proposed in this paper, which is composed of a number of optical fiber and thermocouple sensor. A signal processing circuit of the fiber-optic thermocouple sensor is designed and a cold junction compensation method is also introduced. This paper focuses on analyzing optical fiber sensor signals and the cold junction compensation method in the case of multi-channel temperature measurements. The cold junction compensation method is based on the Newton iterative algorithm, which is embedded in a microprocessor. An experiment of temperature measurement is fulfilled and hence testifies the feasibility of the proposed fiber-optic thermocouple sensor and its cold junction compensation method. |
Les cervidés de la grotte du Vallonnet (Roquebrune-Cap-Martin Alpes-Maritimes) | The cervid family is typical of the big mammals from Vallonnet cave (France), a site of the lower pleistocene. "Cervus" (s.l.) nestii vallonnetensis looks like the villafranchian species and "Praemegaceros" (s.l.) sp. is characteristic of the middle pleistocene period. The result of the comparison between the villafranchian species "Cervus" philisi, "Cervus" perolensis and the Vallonnet middle size specie is a similarity with teeth and bones, and a significant difference of the antlers form. The particularity of these antlers from Vallonnet cave incited us to give the original name : "Cervus" (s.l.) nestii vallonnetensis. There is a relation with the italian deers from lower and middle pleistocene but the ancient attribution to the genus Dama is wrong. New data from last excavations permit us to unify the population of big deer rests from vallonnet cave. There is one specie which is "Praemegaceros" (s.l.) sp. Indeed, the mandibular with a pachyostosis form and the antler form are caracteristic of this genus. |
Cyclitols in maturing grains of wheat, triticale and barley | In the present study, the feeding of stem-flag leaf-ear explants of wheat, triticale and barley with d-chiro-inositol and d-pinitol was used for modification of the composition of soluble carbohydrates in grains without genetic transformation of plants. Maturing grains indicated ability to uptake exogenously applied cyclitols, not occurring naturally in cereal plants, and synthesized their a-d-galactosides. The pattern of changes in soluble carbohydrates during grain maturation and germination was not disturbed by the uptake and accumulation of cyclitols. Both, d-chiro-inositol and d-pinitol as well as their a-d-galactosides can be an additional pool of soluble carbohydrates accumulated by maturing grains, without decreasing seeds viability. This is the first report indicating the possibility of introduction of cyclitols with potentially human health benefits properties into cereal grains. |
Dissonances: Democratic Critiques of Democracy | Guillermo O'Donnell here brings together a collection of significant recent essays in which he considers both the method for and substance of critiques of democracies. While progress has been made in democratization, the authoritarian legacy hangs as a shadow over that advancement. O'Donnell engages in his analysis while keeping a firm gaze on that dangerous past. O'Donnell's work has influenced a generation of political scientists. The essays in this volume bring forward and develop many of the ideas presented in his earlier collection, "Counterpoints: Selected Essays on Authoritarianism and Democracy". This work will be of interest to scholars working in justice reform, democratization, and comparative politics. |
Transport theory of granular swarms. | The transport of trace granular gas (swarm) in a carrier granular fluid is studied by means of the Boltzmann-Lorentz kinetic equation. Time-dependent perturbation theory is used to follow the evolution of the granular swarm from an arbitrary initial distribution. A nonhydrodynamic extension of the diffusion equation is derived, with transport coefficients that are time dependent and implicitly depend on the wave vector. Transport coefficients of any order are obtained as velocity moments of the solutions of the corresponding kinetic equations derived from the Boltzmann-Lorentz equation. For the special case of the initial distribution of swarm particles, transport coefficients are identified as time derivatives of the moments of the number density. Finally the granular particle transport theory is extended by the introduction of the concept of non-particle-conserving collisions. |
A General Maximum Entropy Econometric approach to model industrial electricity prices in Spain: A challenge for the competitiveness | The Spanish Integral Plan of Industrial Policy 2020 points out the energy cost containment as one of the priority actions to improve the competitiveness of industry. In fact, electricity prices for industrial consumers are of particular importance for international competitiveness, as electricity usually represents a significant proportion of its total energy costs. |
Cloning of the hexA mismatch-repair gene of Streptococcus pneumoniae and identification of the product | Abstract The hexA mismatch repair gene of Streptococcus pneumoniae has been cloned into multicopy plasmid vectors. The cloned hexA gene is expressed as judged from its ability to complement various chromosomal hexA − alleles. Its direction of transcription was defined and the functional limits were localized by original methods relying on homology-dependent integration of nonautonomous chimeric plasmids carrying chromosomal inserts into the chromosome. Comparison of the proteins encoded by recombinant plasmids and by restriction fragments allowed us to identify an M r 94000 protein as the probable product of the hexA gene. |
The Ability of the Small Ice Detector (SID-2) to Characterize Cloud Particle and Aerosol Morphologies Obtained during Flights of the FAAM BAe-146 Research Aircraft | Abstract The Small Ice Detector mark 2 (SID-2), which was built by the University of Hertfordshire, has been operated by the Met Office on the Facility for Atmospheric Airborne Research (FAAM) BAe-146 aircraft during a large number of flights. The flights covered a wide range of atmospheric conditions, including stratocumulus, altocumulus lenticularis, cirrus, and mixed-phase cumulus clouds, as well as clear-sky flights over the sea and over desert surfaces. SID-2 is a laser scattering device that provides in situ data on cloud particle concentration and size. SID-2 also provides the spatial light scattering data from individual particles to give some information on the particle shape. The advantage of SID-2 is that it can characterize the cloud particle shape for particle sizes less than the resolutions of the more usual commercially available ice crystal imaging probes. The particle shape characteristics enable, for example, small just-nucleated ice particles to be discriminated from supercooled water d... |
Innovation financière et fiscalité | Without claiming to be exhaustive this article attempts to illustrate some aspects of the relationship between finance and taxation. The subject is addressed through three viewpoints. The first one examines the relationship between fiscal decisions related to public budgets and their effects on the design or changes of financial products. The second one shows how some products are used in a creative way to optimize specific fiscal situations such as the level of profits or the amount of dividends. Finally the third viewpoint is about the creation of new markets linked to fiscal decisions, like the carbon tax. Classification JEL : G0, H31, H32, O31, Q58. |

A study on image searching method in super distributed database | In this paper we propose a new searching method for image information in a super-distributed environment. First, we show that the performance of the search can be evaluated by entropy reduction, and propose a new searching method based on entropy reduction, called the EBS method. Second, we apply the EBS method to image searching using various kinds of query schemes, for example, keyword search, color-pair matching, and browsing. Third, the design concept and experimental results of the prototype system are introduced. |
Can a stroke present with flexor spasms? A highly rare experience | Involuntary movement disorders are not a common presentation of basal ganglia ischemia which may be induced by cerebral hemodynamic insufficiency. In secondary causes of movements disorders cerebrovascular diseases represent up to 22% and involuntary movements develop after 1–4% of strokes. We describe a case of a middle-aged woman who presented with intermittent involuntary tonic spasms or seizure-like episodes followed by weakness due to contralateral putaminal infarction. Initially thought to have Todd’s paralysis she was not thrombolysed, but later she developed dense hemiplegia. Flexor spasms are generally thought to occur in lesions of the spinal cord but they can also occur in cerebral lesion, may be because of disinhibition of the spinal cord. Certain other theories also have been narrated, but this field still needs to be worked upon. |
Stratages and Advances in Improving Resistance to Rice Blast by Transgenic Approaches | Rice blast, which is caused by the fungus Magnaporthe grisea, is one of the most devastating disease occurred in most rice growing areas worldwide. The high variability in pathogenicity of M.grisea isolates makes the control and management of rice blast difficult. Therefore, breeding rice cultivars resistant to the blast disease has been a major goal over several decades. Genetic engineering has emerged as an alternative approach to create blast-resistant rice. Recent researches have shown that the rice cultivars(lines) with broad-spectrum resistance will be produced, by transplanting some genes such as R genes, antifungal-protein genes and bactericidal-protein genes. As for this, this view summarises the improvement programmes from the utilization of the genes referred above. |
Multiple endocrine neoplasia type 1 (MEN1): An update of 208 new germline variants reported in the last nine years. | This review will focus on the germline MEN1 mutations that have been reported in patients with MEN1 and other hereditary endocrine disorders from 2007 to September 2015. A comprehensive review regarding the analysis of 1336 MEN1 mutations reported in the first decade following the gene's identification was performed by Lemos and Thakker in 2008. No other similar papers are available in literature apart from these data. We also checked for the list of Locus-Specific DataBases (LSDBs) and we found five MEN1 free-online mutational databases. 151 articles from the NCBI PubMed literature database were read and evaluated and a total of 75 MEN1 variants were found. On the contrary, 67, 22 and 44 novel MEN1 variants were obtained from ClinVar, MEN1 at Café Variome and HGMD (The Human Gene Mutation Database) databases respectively. A final careful analysis of MEN1 mutations affecting the coding region was performed. |

Competition in the NHS internal market: an overview of its effects on hospital prices and costs. | The 1989 reforms of the UK National Health Service (NHS) introduced competition in the supply of hospital services. This paper synthesizes both the theory underlying the introduction of competition into the NHS, and the limited existing evidence on whether competition affects the prices posted by sellers of medical services, and the costs of producing these services. The results indicate high levels of price variability, widespread disregard for average cost pricing rules and some indication that competition had some effect on prices. It appears that lower prices may be offered to smaller purchasers, such as General Practice Fund Holders (GPFH). This effect of competition on price was mirrored, with a delay, in hospital costs. © 1998 John Wiley & Sons, Ltd. |
Surface enhanced Raman scattering from tris (bipyridine) ruthenium (II) adsorbed on silver-modified p-GaAs | Both surface enhanced Raman scattering (SERS) and surface enhanced resonant Raman scattering (SERRS) have been observed from Ru(bpy)32+ adsorbed on p-GaAs (1 0 0) after the electrodeposition of Ag particles onto the semiconductor surface. For the enhancement factor for SERS a lower limit of 104 has been determined. |
Applying a New Theory to Alter Binge Drinking Behavior in College Students | Binge drinking is a serious public health problem in the United States, where it is estimated that 17.6% adults binge drink. Binge drinking is highest among college students. There is need for effective binge drinking interventions. Recently a new health behavior theory has been proposed called the multitheory model of health behavior change. The purpose of this article is to describe the application of the multitheory model for changing binge drinking behavior to a behavior of responsible drinking or abstaining from alcohol. A framework for an intervention and its testing is presented. |
Risk externalities in a payments oligopoly | I discuss the role to be played by central banks in payment systems by way of an oligopoly model of a payments market where firms exert negative risk externalities upon each other. A central bank participating actively in this market is modelled as benign in two ways: exerting less externalities than other banks and maximizing welfare rather than profit. Because other banks react strategically to the central bank’s presence due to its low externalities, there is a risk that it backfires, with these other banks’ taking more risky positions than if the central bank were not there. The proper role of the central bank may actually be to stay out. |
Poly(Amido-Imide)s Based on Amino-Terminated Oligoimides | An amino-terminated oligoimide was prepared by the Michael addition reaction of ethylene bismaleimide (EBM) and 4,4'-diamino diphenyl methane (DDM) at an EBM:DDM molar ratio of 1:2. The poly(amido-imide)s (PAI)s were prepared by condensation of this EBM:DDM oligoimide with various aliphatic bisesters. The resultant PAIs were characterized by elemental analysis, IR spectral studies, and the number average molecular weight (Mn) estimated by non-aqueous conductometric titration and thermogravimetry. The curing-reaction of an epoxy resin (a diglycidyl ether of bisphenol-A (DGEBA)) with PAI was monitored by Differential Scanning Calorimetry (D.S.C.). Glass and carbon fibre reinforced laminates of PAI-epoxy resin were also prepared and characterized. |
Pattern Collapse - the Mechanical Stability and Solid Bridging of Semiconductor Nanostructures | Pattern collapse is a damage phenomenon during the production of microelectronic devices. Normally, this issue is attributed to surface tension forces during the drying step of a wet clean process; however, in the past several years other influences have been discussed. For the evaluation, the measurement of the mechanical stability of the nanostructures was necessary. Sub-50 nm polysilicon line structures were measured with atomic force microscopy (AFM). The fracture force was found to be influenced by the solid-liquid interface, as much as an increase by 100 %. The concept of solid bridging, where dissolved material in the liquid accumulates between the structures and acts like an adhesive, was studied with silicon nanoparticles. Significant bridges of silicon oxide were observed for evaporative drying. In order to avoid pattern collapse, this formation of bridges, which was attributed to silicates, needs to be prevented. |
Hydraulic-pump fault feature signal extraction method | The invention provides a hydraulic-pump fault feature signal extraction method based on local main value decomposition. Endpoint continuation processing is conducted on collected hydraulic-pump fault signals with a related image method, so that signal endpoints are extreme points; smooth estimation is conducted on extreme values and local mean values with the method of fitting an envelope line through a cubic B spline, so that fitting errors are reduced; then, LMD decomposition is conducted on the preprocessed signals to obtain PF components, correlation analysis is conducted on PFs and the original signals, the real PF components are selected, and finally Hilbert transformation is conducted on the real PF components to obtain Hilbert spectrums of the signals, wherein the Hilbert spectrums are signal features of the hydraulic-pump fault signals. The method is suitable for fault diagnosis of a hydraulic pump in the industrial field. |
Slack resources and firm performance: a meta-analysis | Although organizational research posits various relationships between a firm's slack resources and performance, findings to date have been ambiguous. To provide insight into this relationship, this study employed a meta-analysis based on 80 samples from 66 studies (n=54,249). Results provided evidence of a positive relationship among all three slack types (i.e., available, recoverable, and potential) and financial performance and showed that studies controlling for industry-relative performance demonstrated a stronger positive potential slack–performance relationship than those not including these controls. The analysis also found that studies employing lagged slack measures did not show a stronger positive slack–performance relationship than those employing current year measures for either recoverable or potential slack, a result counter to the one hypothesized. Overall, results highlight the importance of additional research into intervening factors impacting the slack–performance relationship. |
Organizing is Both a Verb and a Noun: Weick Meets Whitehead | Weick’s work on organizing and sensemaking has contributed significantly towards efforts in organization theory to explore organization as process. His discussion of the relationship between verbs and nouns in particular has served to highlight central dynamic features of processes. Weick’s conception of the verb-noun relationship is one of tension between levels of analysis. We propose, drawing upon the work of Alfred North Whitehead, to draw attention to the formation of nouns and how verbs shape nouns and vice versa. We argue that Weick’s work may be extended by looking more closely at the selection of verbs and nouns, i.e. by looking at how selection may be made on the basis of their relationality, thus allowing for their mutual transformation. We illustrate our point using the imagery provided by the ‘pseudopod’. |
Shoulder dystocia: associated with versus caused by the Zavanelli maneuver | thereof. These measures were applied in desperate, frustrating moments, often more than once and commonly by a second accoucher or trainee, all ineffectually. Added to these fetal detriments was the time wasted in fruitless struggle, each moment extending the hypoxia (anoxia?) coincident with the constant cephalic exteriorization. The Zavanelli maneuver was always the last procedure undertaken, the least effortful, and the least time consuming. In 71% of cases, this maneuver was successful on the first attempt. 1 |
Technology of the Preparation of Super-fine Powder | Hwo to prepare super fine pearl powder by jet mill is introduced in this paper. The effects of the parameters of the jet mill on the production particle diameter of the power product and the energy consumed in the mill process are discussed, and the way of how to increase the efficacy of the energy in jet pulverization is also suggested. |
Model Reference Adaptive Control Based on GANN for Vertical Electric Furnace | The vertical electric furnace is a multi-variable complex system, conventional control methods are used to control it, to need modelling and decoupling. In this study, a model reference adaptive control using the Neural Network with Genetic Algorithm (GANN) for the temperature control of the vertical electric furnace is proposed. The neural model of the system is identified by the genetic algorithm. Another neural network is trained to learn the inverse dynamics of the system so that it can be used as a nonlinear controller. Because of the limitation of BP algorithm, the genetic algorithm is used to find the fitness weights and thresholds of the neural network model and the simulation results show that the model is satisfied and the control is effective. |
