Anodic Oxidation of InP in Pure Water | It is shown that thin InP native oxide films can be grown by anodization of InP in pure water. An interfacial phosphorus-rich In(PO/sub 3/)/sub 3/-like condensed phosphate is obtained this way. This condensed phosphate has good passivating properties and can be used in electronic device technology. The chemical composition of these native oxides was found similar to that of an anodic oxide grown in an anodization in glycol and water (AGW) electrolyte. From the similarity between the two depth profiles observed in pure water and AGW electrolyte, they can conclude that dissolution phenomena do not seem to play a major role. The oxide growth seems to be controlled by the drift of ionic species under the electric field. |
Comparison of wild and cultured sea bass (Dicentrarchus labrax) quality | Abstract Chemical composition, nutritional value and other physico-chemical parameters of sea bass from two different geographical areas (Greece and Spain) and from aquaculture and wild origin were studied. Farmed and wild fish differ in proximate composition, colour, and especially in texture, fatty acids and free amino acids (FAAs) profiles. Flesh of wild fish was firmer, which could be attributed to their lower fat content and higher level of activity. Cultured fish showed a higher content of monounsaturated fatty acids and lower of saturated and polyunsaturated fatty acids (PUFAs). Within the PUFA group, n −3 fatty acids were predominant in wild sea bass, while n −6 were more abundant in farmed fish. Some FAAs related to the characteristic flavour of fish, such as glutamic acid, aspartic acid, alanine, and glycine were more abundant in cultured sea bass. No differences between fish from both farms were found, due to the similar composition of the feed used. |
Pairs of Philosophy Relationship in Clinical Work to be Managed | The patient can get better diagnosis and treatment with the development of medical science.In fact,there are misdiagnoses governs by mistake in many hospitals.In order to reduce misdiagnoses governs by mistake,doctors should improve professional skill.As the same time,they should use philosophy principle consciously to deal with specific problems,especially in pairs of relationship of philosophy. |
Stability of nonlinear systems under constantly acting perturbations | In this paper, we investigate total stability, attractivity and uniform stability in ::: terms of two measures of nonlinear differential systems under constant perturbations. Some sufficient ::: conditions are obtained using Lyapunov's direct method. An example is also worked out. |
Internal homogenization: Effective permittivity of a coated sphere | The concept of internal homogenization is introduced as a complementary approach to the conventional homogenization schemes, which could be termed as external homogenization. The theory for the internal homogenization of the permittivity of subwavelength coated spheres is presented. The effective permittivity derived from the internal homogenization of coreshells is discussed for plasmonic and dielectric constituent materials. The effective model provided by the homogenization is a useful design tool in constructing coated particles with desired resonant properties. |
Anodic oxidation of triphenylstibine and electroanalytical investigations of the equilibria involving the oxybis(triphenylantimony) cation produced | Summary The electrochemical oxidation of triphenylstibine at platinum electrodes in “wet” acetonitrile has been studied using cyclic voltammetry and controlled potential electrolysis. Oxybis(triphenylantimony) diperchlorate has been obtained as product and some evidence has been obtained that Ph 3 SbOH + is involved in its formation. The occurrence of hydrolysis equilibria in Ph 3 SbOSbPh 2+ 3 solutions has been confirmed by polarographic investigations. In the cathodic reduction of this cation, evidence for the formation of its complexes with the Lewis base Ph 3 SbO has also been obtained. The complexes Ph 3 SbOSbPh 3 (Ph 3 SbO) 2+ and Ph 3 SbOSbPh 3 (Ph 3 SbO) 2+ 2 were isolated and characterized. |
The unreduced carpal dislocation: a concept of treatment. | The treatment of unreduced carpal dislocations and fracture dislocations is controversial. To obtain reduction, an extensive surgical soft-tissue dissection is usually required. The accompanying damage to vessels, ligaments and articular cartilage increases the risk of symptomatic arthritis of the wrist. To avoid this complication as much as possible, a closed technique of treatment has been developed. The method consists of radiocarpal distraction with an external fixator followed by percutaneous reduction and immobilization with the same external fixator. In five out of six patients with an unreduced carpal dislocation this method appeared successful. |
Elevation of Thyrotropin Release by Intrapituitary Infusion of Crude Hypothalamic Extracts | In rats whose endogenous pituitary secretion had been depressed by phenobarbital and raised ambient temperature (34 C), increases of 131I levels in blood were measured following intrapituitary infusion (4.5–7 μl/hr for 2.5–3 hr) of extracts prepared from the hypothalami of rats and sheep. It was shown that the intrapituitary infusion technique was a sensitive method for testing thyrotropin-releasing factor (TRF) activity provided precautions were taken to prevent cytolysis due to faulty pH or tonicity of the solutions infused. Intrapituitary infusion of dialyzed extracts of rat hypothalamus and of stalk-median eminence (SME) and hypothalamic fragments from sheep at different dosages showed that the magnitude of the response increased with increasing dosage. Intrapituitary infusions of saline or intravenous infusions of sheep hypothalamic extract did not increase blood 131I levels, indicating that neither pituitary damage due to infusion nor TSH contamination of the extracts was responsible for the results... |

The tool uses the ::: inference engine of the CLIPS expert system shell, the CLIPS programming ::: language for developing the expert systems and XML/XSL to specify/implement the ::: user interfaces (in a complete transparent way). It was implemented as a servlet for ::: UNIX environment. |
Measuring and predicting reservoir heterogeneity in complex deposystems. [Quarterly] report, April--June 1993 | The main goal of this research project is to understand reservoir heterogeneity sufficiently to predict optimum drilling locations versus high-risk locations in a given field in order to recommend the most cost-effective infill-drilling programs.The proposed research is designed to use a multidisciplinary approach to measure and map heterogeneity at various scales, and ultimately to develop tools and techniques to predict heterogeneity, both in existing fields and in undrilled areas. Two stratigraphic units have been chosen for this research. The Big Injun sandstone (Mississippian) in West Virginia, and the Rose Run Sandstone (Ordovician) in Ohio and Pennsylvania. |
Non-fragile state estimation for discrete neural networks | In this paper, the non-fragile state estimation issue is investigated for a class of discrete-time neural networks with time-delays. Both linear and nonlinear parts are considered in the network output. The gain variation of the additive type is introduced to depict the possible implementation imprecision in the neuron state estimator. A non-fragile state estimator is constructed which can guarantee the estimation performance against the gain variations. On the basis of the Lyapunov stability theory, sufficient conditions are put forward to ensure that the desired non-fragile state estimators can exist. The explicit expression of the desired estimators is obtained in terms of the solution to a linear matrix inequality. The usefulness and applicability of the proposed design approach are verified by a numerical example. |
X-Ray crystal and molecular structure of hexameric di-t-butylmethyleneaminolithium, (LiNCBut2)6: electron-deficient bridging of Li3 triangles by methyleneamino nitrogen atoms | An X-ray crystallographic study of the title compound, (LiNCBut2)6, has revealed a ‘folded chair’ arrangement of its metal atoms held together by triply bridging methyleneamino groups in what is believed to be the first example of electron-deficient bridging through the nitrogen atom of an organonitrogen ligand. |

Small earthquake scaling revisited: Can it constrain slip weakening | Foodstuffs, beverages, animal feeds, pharmaceutical preparations, and tobacco products are flavored with compounds represented by the formula WHEREIN ONE OF THE SYMBOLS X represents oxygen and the other sulphur and R1 and R2 are hydrogen or methyl radicals. The flavoring compounds or their solutions can be used either alone or in combination with other flavor ingredients. |
Management of pelvic lymphoceles following robot-assisted laparoscopic radical prostatectomy | Pelvic lymphocele is a potential complication of radical prostatectomy. Although lymphoceles often regress spontaneously, many may progress, precipitate clinical symptoms, and ultimately require intervention. To date, the best treatment of pelvic lymphoceles has not yet been fully defined. However, laparoscopic marsupialization is a definitive and efficacious surgical alternative to percutaneous drainage. It is effective, results in minimal patient morbidity, and allows for rapid recovery. We report our experience with management of clinically symptomatic pelvic lymphoceles following robotic-assisted prostatectomy using laparoscopic marsupialization. |
Triphosphoinositide phosphomonoesterase in rat kidney cortex: II. Purification and characterization☆ | Abstract Triphosphoinositide phosphomonoesterase was purified 50-fold from homogenates of the rat kidney cortex by procedures involving treatment of microsomal fractions with 0.5% sodium desoxycholate, sonication in the presence of 0.5% sodium desoxy cholate, and ammonium sulfate fractionation. Evidence was presented for the enzymatic hydrolysis of triphosphoinositide according to the reaction: Triphosphoinositide → Diphosphoinositide + Inorganic phosphate ↓ Monophosphoinositide + Inorganic phosphate Results of mixed-substrate experiments, the effect of divalent metalions, inhibitor studies, and the Arrhenius plot strongly support the view that triphosphoinositide phosphomonoesterase is a separate and distinct enzyme from alkaline phosphatase. |
Synthesis of p-aminophenol by means of electrochemical reduction | p-Aminophenol is an important raw material and intermediate in organic synthesis. In recent years, many scholars have paid attention to it. Synthesis of p -aminophenol by means of electrochemical reduction is reviewed particularly ,the advantage and disadvantage of this method are reviewed in this article. |
The Foreign Policy Beliefs of Women in Leadership Positions | FEW PREDICTIONS ABOUT SOCIAL CHANGE seem as safe as the proposition that women will play an increasingly important role in leadership positions. However one may judge the pace of change in this respect, there can be little disagreement about the trend.' If that premise is valid, how will this development affect politics? Will it bring a higher standard of probity to the political process? A more humane set of concerns into the establishment of political agendas? In the realm of external affairs, will it give rise to more serious concern and a higher priority for undertakings that often fall outside the purview of those espousing or practicing realpolitik diplomacy? These questions imply that women may bring to the political process a set of beliefs or worldviews that differ systematically from those of their male counterparts. |
Perturbational crystal orbital theory in matrix form | In this paper a formalism, called perturbational crystal orbital theory, is proposed and examined. This formalism is based on a recent formulation of the perturbational molecular orbital theory in matrix form, and could be considered as an extension of it to periodic lattices. The perturbational crystal orbital theory is applied to the study of the energy band changes due to geometrical and electronegative perturbations of a 1D lattice. For these cases, the exact results are compared with those obtained by applying the proposed formalism up to second order, and a discussion of those results is carried out. |
EFFECT OF STRESS-INDUCED REACTIONS ON MORPHOLOGICAL STRUCTURE AND PROCESSABILITY OF PVC DURING PAN-MILLING | The effect of pan-milling on morphological structure, processability and properties of PVC was studied through SEM, FTIR, granulometer, GPC and mechanical properties test in the hope of gaining ease in operation, needless of plasticizers, a clean and efficient route for improving the processability of PVC through stress-induced reactions, fulfilling the idea of "plasticizing PVC by itself". The experimental results show that during pan-milling at ambient temperature, within 2–3 min, the microcrystalline structure of PVC becomes indistinct, the grain size of PVC is reduced from 130–160 μm to 1–50 μm, the molecular weight of PVC is slightly decreased, the variation of molecular weight distribution is indistinct, the plasticizing time and torque at balance drop a great deal from 71–132 s to 31–33 s and from 18.2–22.1 Nm to 14.7–18.4 Nm, respectively, the processability of PVC is markedly improved, and the mechanical properties get enhanced too. |
Structural Transition at 360 K in the CaFe5O7 Ferrite: Toward a New Charge Ordering Distribution | An efficient synthesis route is proposed to obtain single phase powder ceramic of CaFe5O7. This complex structure can be described as an intergrowth between one CaFe2O4 unit and n = 3 slices of FeO Wustite-type structure. A detailed structural study has been carried out at room temperature combining transmission electron microscopy (TEM) observations (ED, HREM), scanning transmission electron microscopy (STEM-HAADF), and X-ray diffraction data. The analysis of these data has revealed an unexpected supercell with a monoclinic symmetry. From the hkl conditions deduced from the electron diffraction study and the analysis of X-ray diffraction data by simulated annealing, a structural model considering the centrosymmetric P21/m setting can be proposed. In addition the first magnetic and electrical transport measurements are reported showing a sharp peak in magnetic susceptibility and a strong localization around 360 K, associated to a structural change from monoclinic setting to orthorhombic one. |
Nucleophile assistance of electron-transfer reactions between nitrogen dioxide and chlorine dioxide concurrent with the nitrogen dioxide disproportionation | The reaction of chlorine dioxide with excess NO2- to form ClO2- and NO3- in the presence of a large concentration of ClO2- is followed via stopped-flow spectroscopy. Concentrations are set to establish a preequilibrium among ClO2, NO2-, ClO2-, and an intermediate, NO2. Studies are conducted at pH 12.0 to avoid complications due to the ClO2-/NO2- reaction. These conditions enable the kinetic study of the ClO2 reaction with nitrogen dioxide as well as the NO2 disproportionation reaction. The rate of the NO2/ClO2 electron-transfer reaction is accelerated by different nucleophiles (NO2- > Br- > OH- > CO32- > PO43- > ClO2- > H2O). The third-order rate constants for the nucleophile-assisted reactions between NO2 and ClO2 (kNu, M-2 s-1) at 25.0 °C vary from 4.4 × 106 for NO2- to 2.0 × 103 when H2O is the nucleophile. The nucleophile is found to associate with NO2 and not with ClO2 in the rate-determining step to give NuNO2+ + ClO2-. The concurrent NO2 disproportionation reaction exhibits no nucleophilic effect a... |

Outline of a Theory of Statistical Estimation Based on the Classical Theory of Probability | We shall distinguish two aspects of the problems of estimation . (i) the practical and (ii) the theoretical. The practical aspect may be described as follows: (i a ) The statistician is concerned with a population, π, which for some reason or other cannot be studied exhaustively. It is only possible to draw a sample from this population which may be studied in detail and used to form an opinion the values of certain constants describing the properties of the population π. For example, it may be desired to calculate approximately the mean of a certain character possessed by the individuals forming the population π, etc. |
Effects of Management Strategies on the Reproductive Success of Least Terns on Dredge Spoil in Georgia | Abstract Sterna antillarum antillarum (Eastern Least Tern) historically nested on Atlantic Coast beaches and barrier island shores, but has moved inland to artificial habitats, such as dredge-spoil sites, as available natural habitat has been lost to development and increased human recreational activities. Least Terns readily nest on artificial sites, but the effects of different habitat characteristics and depredation conditions on reproductive success are unclear. We examined the effects of management strategies, disking and electric fencing, on daily survival rate (DSR) and 21-day survival rate (DSR21) of clutches, and on apparent nesting success on a dredge-spoil site in Georgia from 1993 through 1998. All 3 estimates of reproductive success increased as management intensity increased. Significantly (χ22 = 185.8, P < 0.001), DSR increased from 0.88 (1993, no management) to 0.97 (1998, disking in March to remove vegetation and enclosure with an electric fence). Corresponding DSR21 were 0.06 and 0.59, r... |
Chapter 5.3 Passive Continental Margin Evolution | Abstract This chapter reviews the litho-, chemo-, bio- and chronostratigraphic evolution from the rift–drift transition to the onset of basin closure as recorded in the various tectonic units of the Damara Orogen sensu lato . This stage of basin evolution includes the deposition of two major glaciogenic units, generally correlated with the global Sturtian and Marinoan glaciations, and well-developed cap carbonate successions, as well as the formation of oceanic crust, relics of which are present in the southern Damara Belt and the western Gariep Belt. |
Cumulative Beam Breakup in Linear Accelerators with Arbitrary Beam Current Profile | An analytical formalism for the solution of cumulative beam breakup in linear accelerators with arbitrary time dependence of beam current is presented, and a closed-form expression for the time and position dependence of the transverse displacement is obtained. It is applied to the behavior of single bunches and to the steady state and transient behavior of dc beams and beams composed of point-like and finite length bunches. This formalism is also applied to the problem of cumulative beam breakup in the presence of random displacement of cavities and focusing elements, and a general solution is presented. |
Nonlinear Constitutive Equations for Creep of Structural Materials | Nonlinear constitutive equations for time dependent anisotropic materials and related kernel functions were described. Some assumptions based on structural symmetry and material restrictions suggested to simplify involved constitutive equations were overviewed. In order to verify theories thin walled tubular specimens of wood and fiber glass reinforced polyester were subjected to various combinations of tension, torsion and internal pressure. The time dependence of creep strains and the forms of kernel functions were discussed. |
Hyperspectral sensor for civil applications to Unmanned Aerial Vehicles within a monitoring scenario | This paper deals with a possible exploitation of a hyperspectral sensor, as an UAV integrated subsystem, in civil monitoring scenarios. Starting from the description of the hyperspectral technology, exploitation domains and possible advantages of unmanned airborne applications, this article addresses some important specific issues for monitoring scenarios. An example is carried out highlighting the most challenging issues concerning the sensor integration on an Unmanned Air Vehicle, both from the structural and the mission planning point of view. In the end, some suggestions aimed at guaranteeing an optimal regular service for monitoring activities are proposed. |
Testing Square-Freeness of Strings Compressed by Balanced Straight Line Program | In this paper we study the problem of deciding whether a given compressed string contains a square. A string x is called a square if x = zz and z = uk implies k = 1 and u = z. A string w is said to be square-free if no substrings of w are squares. Many efficient algorithms to test if a given string is square-free, have been developed so far. However, very little is known for testing square-freeness of a given compressed string. In this paper, we give an O(max(n2,n log2 N))-time O(n2)-space solution to test square-freeness of a given compressed string, where n and N are the size of a given compressed string and the corresponding decompressed string, respectively. Our input strings are compressed by balanced straight line program (BSLP). We remark that BSLP has exponential compression, that is, N = O(2n). Hence no decompress-then-test approaches can be better than our method in the worst case. |
Representations of the Lie Algebra of the Homogeneous Galilei Group and Their Relation to the Representations of the Lorentz Algebra | The irreducible Hermitian representations of the Lie algebra of the homogeneous Galilei group were first constructed by using the method of the maximal compact subgroup. The same representations were then obtained by contracting the irreducible representations of the homogeneous Lorentz group. In the Appendix, the faithful representations are given with the diagonalized generators of the velocity transformations. |

Dancing bees evaluate agricultural forage resources as inferior to central urban land | Recent evidence suggests that flower-rich areas within cities could play an important role in pollinator conservation, but direct comparison of agricultural and urban areas has proved challenging to perform over large scales. Here we use the waggle dances of honeybees (Apis mellifera L.) to evaluate floral resource availability over the entire season at deeply urban or agricultural sites. Through analysis of 3378 dances that were performed over two years by 20 colonies in SE England, we show that foraging trip distance is consistently lower at urban sites across the entire season, implying a higher availability of forage in heavily urbanized areas. Urban bees also collected nectar with a higher mean sugar content. From the self-reported perspective of a generalist pollinator, the modern agricultural landscapes that we studied provided insufficient and transient resources relative to heavily urbanised areas, which may represent important refuges within an impoverished landscape. |
An organic compound polymer emit light element | Between the present invention a charge-transporting ability to have metal electrodes and the charge transfer substance capable of chemical bonding (charge transfer complex, charge transfer salt) the same or two metal electrodes that are dispersed in a polymer, a metal electrode and an organic material or polymer light-emitting layer to form a thin film layer is proposed to this structure, and a manufacturing method of the organic / polymer light emitting device to increase the light emission efficiency. |
Sink depth of trolled fishing lines | During recreational troll fishing, success usually depends on the ability to maintain the lure at the desired depth. When trolling with a heavy line, one whose inherent density sinks the lure, depth control is guesswork for most anglers. This study presents a method for predicting the trolling depth of heavy fishing lines. The model is developed based on the fluid mechanics of the line being towed through quiescent water and determines line depth for known line properties and trolling speed. Experiments are performed to validate the model and results are consistent with the model predictions. The model is employed to illustrate how trolling depth can be controlled during typical fishing situations. |
Optical demonstration of chlamydiae in cell cultures by means of fluorochrome 33 258 H | Fluorochrome 33 258 H, a bisbenzimidazole, was employed for demonstratingChlamydiae in cell cultures, and proved to be particularly suitable for illustrating the unique intracellular reproduction processes of these organisms. The staining procedure is simple and permits a selective differentiation of chlamydial inclusions and their developmental processes in the cell. Contrary to other staining methods, all stages of the chlamydial reproduction cycle can be illustrated thus permitting the early demonstration ofChlamydiae in the cell. The procedure is suitable not only in experimental investigations onChlamydiae but also in clinical diagnostics. |
Modelling of power electronic loads in AC distribution systems using the generalized state space averaging method | Most of the loads in AC distribution systems have positive incremental impedance characteristic. However, power electronic loads, when tightly regulated, sink constant power from the system. Therefore, they have negative incremental impedance characteristic. This can even cause negative impedance instability. Power electronic loads usually have a controlled or uncontrolled rectifier at the front end. In this paper, these loads are modelled using the generalized state space averaging method. An assessment of their effects in AC distribution systems is also presented. |
Violation of the equivalence principle oscillation solutions to the solar neutrino problem | We study the solar neutrino problem within the framework of a parametrized post-Newtonian formulation for the gravitational interaction, which incorporates a violation of the equivalence principle (VEP), and examine the more important VEP effects using the current data on the rates and the energy spectrum. We find two possible solutions for the neutrino rate, one of them involving the MSW effect in matter and the other corresponding to a vacuum oscillation. In both cases, a semi-annual seasonal modulation of the neutrino flux is predicted, because of the anisotropic contributions to the gravitational effects. Our analysis provides new constraints for some VEP parameters. |
[Role of lung biopsy in diagnosis of pulmonary pathology at the prehospital level]. | The aim of the work was to assess the value of biopsy techniques for fibrobronchoscopy under local anesthesia in patients with pulmonary pathology at the prehospital level. It included 706 subjects with lobular, segmental or diffuse lesions in the lungs of specific (tuberculosis), non-specific (pneumonia, exogenous alveolitis), and other origin. All known methods of endobronchial biopsy were employed (bronchoalveolar lavage or liquid lung biopsy, tissue biopsy, transbronchial biopsy, brush biopsy, puncture and aspiration biopsy) with subsequent cytomorphological and bacteriological studies of bioptates. Diagnostic efficiency of direct biopsy was estimated at 97%, transbronchial biopsy at 5-90% depending on nosological form of lung disease, brush and puncture biopsy 20-50 and 6% respectively. Reversible complications occurred in 1.4% and were resolved by therapeutic methods. Cost effectiveness of prehospital instrumental examination of patients with pulmonary pathology is 10 times the intrahospital one. |
A Multi-Agent System for the Dynamic Emplacement of Electric Vehicle Charging Stations | One of the main current challenges of electric vehicles (EVs) is the creation of a reliable, accessible and comfortable charging infrastructure for citizens in order to enhance demand. In this paper, a multi-agent system (MAS) is proposed to facilitate the analysis of different placement configurations for EV charging stations. The proposed MAS integrates information from heterogeneous data sources as a starting point to characterize the areas where charging stations could potentially be placed. Through a genetic algorithm, the MAS is able to analyze a large number of possible configurations, taking into account a set of criteria to be optimized. Finally, the MAS returns a configuration with the areas of the city that are considered most appropriate for the establishment of charging stations according to the specified criteria. |
Head-to-tail and side-by-side oligomerization of human carbonic anhydrase II: a small angle X-ray scattering study. | Abstract Solvent-induced directional aggregation of human carbonic anhydrase II (hCA) was studied by small angle X-ray scattering and fluorescence and fourth-derivative ultraviolet absorption spectroscopy. We propose that hCA at 5 mg ml −1 in pure water forms head-to-tail oligomers built up, on average, by four to five monomers. At higher protein concentrations, the oligomers associate pair-wise and side-by-side. Spectroscopic evidence suggests that the subunits forming the aggregates are tightly folded, but with a structure that differs, at least locally, from the native state. A more complex aggregation pattern was observed under solvent conditions that favor the removal of zinc from the enzyme-active site, conditions under which the subunits are significantly less compact than in water. hCA may provide a useful model to investigate the effects of additives and genetic manipulation on protein aggregation. |
A TENTATIVE TECHNICAL DISCUSSION ON DATA ACQUISITION FOR TUNNEL ADVANCED GEOLOGICAL PREDICTION | From the angle of applied technology,this paper deals with the theory and data acquisition method of TSP tunnel advanced geological prediction,and discusses the technology of TSP data acquisition in the aspects of exciting configuration,receiver configuration and acquisition parameter.The method of parameter choice for extremely hard rock,hard rock and soft rock is also discussed.With case study,the means for getting high quality raw data is illustrated. |

A Study on the Apparel Sizing System of ISO for Chinese Adult Women | This study materializes body type measurement based on ISO(International Standard Organization)size system, targeting 1381 Chinese women, and suggests clothes size standards. It provides basic information on Chinese women size for Korean clothes companies advanced in China to strengthen the national competitiveness of Korean clothing industry. First, after the body type examination, based on the ISO's drop value, the results of types are in its decreasing order: A, M, H, and D. Second, women upper garment sizes by body types are set in the section of height 152cm, 160cm, and 168cm. Garment sizes are suggested based on the section that has more than 0.8% of appearance rate for the survey target: A, H, and M. Third, the clothes sizes of women pants are set in the section of height 152cm, 160cm, and 168cm just with the same as the upper garment. |
Study of the moving track of superhot electrons in an inhomogeneous magnetic field | The moving track of superhot electrons in an inhomogeneous magnetic field is studied in detail. It would be very useful for designing a magnetic spectrometer to study superhot electrons. |
Study on the yield loss of the cucumber harmed by Liriomyza sativae Blanchard and the target of its prevention and control | Investigation and analysis were conducted of the yield loss of the cucumber harmed by Liriomyza sativae Blanchard, and of the index of insect pest situation. The results showed that the higher the index of insect pest situation was, the greater the yield loss; and that the positive interrelation was highly significant, when the index of insect pest situation came up to 15～17, it was the target of the prevention and control. |
SIMULATION OF A CHANNEL CONTROL SCHEME FOR ERROR DETECTION AND CORRECTION IN WIRELESS COMMUNICATION SYSTEMS | Previous studies have shown that the presence of noise and other impairments in communication channels causes error in data during its transmission. By coming up with an effective means of detecting and correcting errors, the rate at which erroneous data manifest is brought to minimal during communication. This paper presents an effort to simulate a simple, effective method of designing a convolutional coding scheme in channel control for error detection and correction in mobile wireless time division multiple access system. The simulation results show a 50% improvement over other method of error detection and correction which involves a combination of turbo coding and low density parity checks. |
Effect of herbimycin A, an inhibitor of tyrosine kinase, on protein tyrosine kinase activity and phosphotyrosyl proteins of Ph1-positive leukemia cells. | Herbimycin A, a benzoquinonoid anasamycin antibiotic, preferentially inhibited the in vitro growth of Ph1-positive leukemia cell lines. On the other hand, genistein, which was developed as an inhibitor of receptor-type tyrosine kinase, and other protein kinase inhibitors showed no selective inhibition of Ph1-positive leukemia cell growth. Herbimycin A also displayed an abrogative effect on the transformation of murine hematopoietic cells by transfection with a bcr/abl oncoprotein-expressing retroviral vector. The antitumor action of herbimycin A on Ph1-positive leukemia cells is related to an inhibition of activity of bcr/abl protein tyrosine kinase and a subsequent reduction of the constitutive phosphotyrosyl proteins, however, the antibiotic has no effect on the expression of bcr/abl mRNA and oncoprotein. Therefore, herbimycin A may provide an important insight into the oncogenic action of bcr/abl oncoprotein and the future development of oncoprotein-targeted therapeutic agents. |
On the ratio of the maximum term and the maximum modulus of the sum of two entire functions | Some results on the sum of two entire functions pertaining to the ratio of the maximum term and the maximum modulus are proved. |
Interoperability of cross-lingual and cross-document event detection | We describe a system for event extraction across documents and languages. We developed a framework for the interoperable semantic interpretation of mentions of events, participants, locations and time, as well as the relations between them. Furthermore, we use a common RDF model to represent instances of events and normalised entities and dates. We convert multiple mentions of the same event in English, Spanish and Dutch to a single representation. We thus resolve crossdocument event and entity coreference within a language but also across languages. We tested our system on a Wikinews corpus of 120 English articles that have been manually translated to Spanish and Dutch. We report on the cross-lingual cross-document event and entity extraction comparing the Spanish and Dutch output with respect to English. |
Synthesis of a novel bipyrimidine dicarboxylic acid ligand for the preparation of panchromatic ruthenium dyes | Abstract A novel ruthenium complex with a new 4,4’-bipyrimidine-6,6’-dicarboxylic acid ligand (H2dcbpm) has been synthesized and its properties were investigated for application in dye-sensitized solar cells. The new dye shows a wide range of absorption of the solar spectrum with maximum of absorption at 665 nm corresponding to a 100 nm redshift compared to the precursor complex ([Ru(dcbpyH2)2(Cl)2]) of the commercial N719 dye. The energies of HOMO-LUMO obtained by voltammetry and DFT calculations show an overall stabilization of the orbitals of the bipyrimidine complex compared to the bipyridine one. Despite having promising absorption properties, the redox potentials of this complex make it unsuitable for charge injection into the conduction band on TiO2. Nevertheless, the newly prepared ligand provides an additional tuning path to adjust the energy levels of the complex in order to benefit from the red-shifted absorption it offers. |
Neuropath planner–automatic path searching for neurosurgery | Abstract This paper describes an improvement of automatic neurosurgical path searching algorithm which incorporates the structure of blood vessels. We have proposed an automatic searching method for surgical path planning on neurosurgery to realize minimally invasive operations within the range of soft tissues. This path searching is based on importance values we defined, and an anatomical structure database generated from MRI images and surgeon experiences. This paper introduces blood vessels into the path searching because we cannot give them damages during operation. We first obtain the structure of blood vessels from MRA, then also give them importance values, and finally incorporate the structure into path searching. Experimental results show that the path obtained by the proposed method is better than searching without vessel structure. |
A name for the 'blueberry tetra', an aquarium trade popular species of Hyphessobrycon Durbin (Characiformes, Characidae), with comments on fish species descriptions lacking accurate type locality. | A new species of Hyphessobrycon is described from a tributary of the upper Rio Tapajós, Amazon basin, Mato Grosso, Brazil. Its exuberant colour in life, with blue to purple body and red fins, is appreciated in the aquarium trade. Characters to diagnose the new species from all congeners are the presence of a single humeral blotch, absence of a distinct caudal-peduncle blotch, absence of a well-defined dark mid-lateral stripe on body, the presence of 16-18 branched anal-fin rays, nine branched dorsal-fin rays and six branched pelvic-fin rays. A brief comment on fish species descriptions solely based on aquarium material and its consequence for conservation policies is provided. |

Control of Bacillus Contaminating Date Palm Tissue in Micropropagation Using Antibiotics | Microbial contamination is one of the most important causes of losses in in vitro culture [1]. Yeast, fungi or bacteria are frequently isolated [2–6]. The most serious contamination is caused by bacteria which reduce the multiplication and rooting speed and can cause the death of tissues [7,8]. To control bacterial contaminants in tissue culture, several trials have been undertaken by different authors using antibiotics [9–13]. Their success, however, depends on the kind of bacteria involved. |
Native and artificial radiation-induced defects in montmorillonite. An EPR study | A natural montmorillonite containing radiation-induced defects was studied with Electron Paramagnetic Resonance (EPR) spectroscopy (X- and Q-band). A first dominant native defect, namely native defect 1, is identified. It gives rise to an orthorhombic spectrum with gx= 2.004 ± 0.005 gy= 2.010 ± 0.003, gz= 2.065 ± 0.002. Simulation of the EPR spectrum at X- and Q-band reveals a second native defect with isotropic spectrum at g= 2.019 ± 0.005. Both are electron holes trapped on oxygen atoms of the structure. The native defect 1 is located on an oxygen-silicon bond or a non-bonding orbital parallel to the c* axis. These defects are annealed at 500°C and the half-life determined for native defect 1 is circa 3,000 years. Irradiations with beta rays produced two additional hole centers of lower stability and distinct EPR parameters. Artificial irradiations show that montmorillonite can be used as a dosimeter in a large dose range. |
Novel controllers for high performance aircraft | H/sub infinity / robust control techniques are applied to the pitch rate control of a modern combat aircraft. The linearized equations of motion are unstable and contain a low-frequency non-minimum phase zero. A novel technique is presented which allows a small degree of closed-loop instability thus avoiding the usual trade-offs inherent in such systems. > |

The main factor is the rules of functional bacteria diversification on the nitrogen transitions and soil enzyme transformation and the functional intensity on the nitrogen transitions. |
Safety and Efficacy of Iron(III)-hydroxide Polymaltose Complex | The following review of iron(III)-hydroxide polymaltose complex (IPC, Maltofer®) shows that iron is significantly bioavailable after oral administration, especially in iron-deficient subjects. Numerous clinical trials in men, women, children and infants have shown that IPC is effective in treating iron deficiency anaemia (IDA). Due to its kinetic properties, IPC is best given with meals, and probably in an iron dose slightly higher than that of the classical iron salts. In terms of acceptance and patient compliance, IPC presents a clear advantage over ferrous salts. Many studies have shown a lower rate of treatment interruption with IPC than with ferrous salts. This is usually associated with a lower incidence of adverse events related to the upper gastro intestinal tract. |
Compositional Branching-Time Measurements | Formal methods are used to increase the reliability of software and hardware systems. Methods such as model checking, verification and testing are used to search for design and coding errors, integrated in the process of system design. Beyond checking whether a system satisfies a particular specification, we may want to measure some of its quantitative properties. Earlier works on system measurements suggest extending model checking techniques to measure quantitative artifacts, based on weights associated with the transitions of a transition system. Other works allow counting while performing model checking or runtime verification. This paper presents a simple and efficient compositional measuring framework based on quantitative state testers. The framework allows combining multiple measures, such as distance and power consumption, using a variety of functions, such as min, max, and average. This supports calculation of interesting compound measures that quantitatively characterize a system’s behavior. |
COMPARATIVE STUDIES OF THE NODAL AND VASCULAR ANATOMY IN THE NEOTROPICAL CYATHEACEAE. III. NODAL AND PETIOLE PATTERNS; SUMMARY AND CONCLUSIONS' | of leaf traces. A characteristic petiole pattern is found in all members of the Cyatheaceae. There is an increase in the complexity of the petiole vascular tissue which results in a gradation from the undivided strand in Metaxya, to the three-parted petiole pattern in Lophosoria, and finally to the much-dissected petiole vascular tissue in the advanced genera. Nodal and vascular anatomy data basically support Tryon's phyletic scheme for the family. The SphaeropterisAlsophila-Nephelea line shows certain tendencies toward increased complexity of nodal and vascular anatomy, whereas the Trichipteris-Cyathea-Cnemidaria line shows the same anatomical and morphological characters in a direction of increased simplification or reduction. |

Modelling rate distributions using character compatibility: implications for morphological evolution among fossil invertebrates | Rate distributions are important considerations when testing hypotheses about morphological evolution or phylogeny. They also have implications about general processes underlying character evolution. Molecular systematists often assume that rates are Poisson processes with gamma distributions. However, morphological change is the product of multiple probabilistic processes and should theoretically be affected by hierarchical integration of characters. Both factors predict lognormal rate distributions. Here, a simple inverse modelling approach assesses the best single-rate, gamma and lognormal models given observed character compatibility for 115 invertebrate groups. Tests reject the single-rate model for nearly all cases. Moreover, the lognormal outperforms the gamma for character change rates and (especially) state derivation rates. The latter in particular is consistent with integration affecting morphological character evolution. |
Selective sodium removal from lithium chloride brine with novel inorganic ion exchanger | Natrium superionic conductor (NASICON) ceramics present interesting sensitive and selective properties against alkaline cations due to their structure. The powder of Li 1.4 La 0.4 Zr 1.6 (PO 4 ) 3 has been synthesized by a solid phase reaction. The removal of sodium was studied in an extensive series of tests involving different ionic exchange process variables such as time and temperature. The results indicated that its exchange capacity is very high, even reach 41.3 mg/g. The Na/Li ion exchange reaction rate increased obviously with increasing temperature, and the kinetic data fitted well to the equation of Johnson-Mehl-Avrami-Kolmogorov with a regression coefficient value of above 0.99. KEY WORDS : Brine, Lithium chloride, Sodium, Separation Bull. Chem. Soc. Ethiop. 2013 , 27(2), 241-248. DOI: http://dx.doi.org/10.4314/bcse.v27i2.9 |
Exploring the unique and interactive roles of distress tolerance and negative urgency in obsessions | Abstract Recent research has implicated relationships between emotion dysregulation and obsessions. Evidence suggests low distress tolerance and greater tendency to act impulsively in the face of negative affect (or negative urgency) are strongly related to obsessions. The current study sought to examine the unique and interactive roles of distress tolerance and negative urgency in the prediction of obsessions. A large non-clinical sample ( N = 238) was administered a range of self-report measures. Results revealed that both poor distress tolerance and greater negative urgency were uniquely associated with obsessions but not other obsessive–compulsive symptoms, even when controlling for gender, depression, anxiety, and generalized anxiety disorder symptoms. Additionally, low distress tolerance and high negative urgency interacted with each other in the prediction of greater obsession symptoms. Overall, the findings help clarify the emerging literature linking emotion dysregulation to obsessions. |
Diversity of phlD alleles in the rhizosphere of wheat cropped under annual rice-wheat rotation in fields of the Indo-Gangetic plains : influence of cultivation conditions | The antibiotic 2,4-diacetyphloroglucinol is a major determinant in the biocontrol of plant growth promoting rhizobacteria associated with crops of agronomic relevance. The phlD gene is a useful marker of genetic and phenotypic diversity of 2,4-DAPG-producing rhizobacteria. A two-step amplification procedure was developed in order to assess directly the presence of phlD in environmental DNA, avoiding the tedious procedure of phlD-positive strain screening and isolation. We found a predominance of one or two phlD alleles in wheat fields cultivated in rice–wheat rotations for twenty years, suggesting that continuous rice–wheat cropping would lead to an enrichment of particular phlD genotypes. We also recovered new sequences with no close relative among known phlD sequences, indicating that part of the phlD allelic diversity might have been missed using standard media culture conditions. |
The effect of using the Breeding Soundness Evaluation as a selection criterion for Santa Gertrudis bulls on bulls in subsequent generations | Abstract Results of Breeding Soundness Evaluations (BSE) used to select Santa Gertrudis bulls over a 10-yr period were analyzed in retrospect to determine the effect on bulls in subsequent generations. Bulls were tested at three ages: 16 mo (n = 1,936), 20 mo (n = 3,111) and at maturity (≥ 24 mo, n = 3,814). Scrotal circumference (SC) and sperm motility and morphology were evaluated. Sixteen-mo-old bulls were required to have an SC ≥ 30 cm to be tested. During 1977 to 1980, 20-mo-old bulls with an SC |
Morphology controlled Si-modified LiNi0.5Mn1.5O4 microspheres as high performance high voltage cathode materials in lithium ion batteries | Abstract Well-crystallized, microspherical LiNi 0.5 Mn 1.5−n Si n O 4 (0.05 0.5 Mn 1.45 Si 0.05 O 4 microspheres is achieved, which is superior compared to 93.1% capacity retention of the pristine LiNi 0.5 Mn 1.5 O 4 microspheres. Since the Si O bond exhibits higher dissociation energy compared to the dissociation energies of the Mn O or Ni O bonds, the excellent electrochemical performance might be associated with an increased structural and chemical stability caused by incorporation of silicon into the oxygen rich crystal lattice. |
Resource Management for Manufacturing Grid Based on Comprehensive Optimization Algorithm | This paper proposes a new method: PCA- Optimal SVM model which is composed of PCA and Optimal SVM to optimize the allocation of manufacturing grid resources through resources allocation data. The model is fit for company in the small sample space. It uses PCA to predigest the input vector and uses Optimal SVM to judge the statement of the company resources. With the model, one or more enterprises could be selected in every process in full lifecycle of product, and the defects in resolving optimal configuration with traditional algorithm model could be omitted. The application case proved that the proposed method can improve the feasibility of the program in optimal configuration, and it is suitable for on-line resource optimal configuration control for manufacturing grid. |
A wafer level vacuum packaged silicon vibration beam accelerometer | This paper gives a detail description of a silicon vibration beam accelerometer which was fabricated by SOI technology and encapsulated in a wafer level vacuum package. The wafer level package gives advantage of small size and low cost, but also produce additional residual stresses that increased the temperature coefficient of the vibration beams. To solve this problem, the sensing structure was redesigned and reduce the temperature coefficient from 50Hz/℃ to 10Hz/℃. Moreover, with carefully assembly, control and measure technology, the accelerometer system achieved reliable performance. Experiment result shows that the scale factor was 120Hz/g, measurement rang was ±50g with non-linearity coefficients of 19μg/g2 and 0.06μg/g3, resolution was 10μg/sqrt(Hz), bias Allan variance was 10μg. |
Identification and discrimination of eight Greek grape cultivars ( Vitis vinifera L.) by random amplified polymorphic DNA markers | Fifteen decamer primers of an arbitrary nucleotide sequence were used to amplify genomic DNA by polymerase chain reaction (PCR-RAPD) in order to identify and discriminate between 8 cultivars of Vitis vinifera L., grown at the Island of Crete. Over 140 reproducible polymorphic fragments were generated by this method. Each grape cultivar showed a unique banding pattern for more than 5 of the primers used. Herefrom, the degree of genetic similarity was calculated and the dendrogram of the 8 cultivars was constructed. The results show that RAPD is a reliable and very useful method for the identification and genomic analysis of grape cultivars. |

Teaching and Control of Robot Contour-Tracking Using Contact Point Detection | New methods for teaching and controlling contour-tracking tasks based on contact sensing are developed to improve robotic machining. Accurate contact point detection is introduced to estimating a work contour path with high reliability. The framework is described that control references for a robotic manipulator are calculated from the estimated work contour path and task specifications. Then, teaching methods are developed assuming that the contact sensing method is applied to obtain the work contour path in teaching process and to obtain the path during task execution. These teaching methods reduce the effort for task teaching and improve adaptability to handle changes in task specifications without re-teaching. Real-time contour tracking control using this contact sensing to suppress work uncertainties in process is presented. Experimental results for practical grinding tasks using a 6 DOF manipulator validate our methods. |

A privacy protection advertisement (Ads) system based on cloud computing and indoor location technology is proposed In addition, the data flow in overall system is explained. The designed Ads system not only provides personalized real-time advising but also protects privacy of customers. Moreover, it can benefit the offline system optimization and increase sales. |
End adsorption of polymer brushes | We study the adsorption of a polymer brush on a solid plate parallel to the plate where the chains are grafted in the limit where only the free-end monomers of the grafted chains adsorb. In the vicinity of the adsorbing plate, there exists a dead zone where no free chain ends are found; the monomer concentration is constant in this region and parabolic close to the grafting plate. In the absence of external force, the equilibrium distance between the two plates is smaller than the natural brush size. The fraction of chains forming bridges increases linearly with the adsorption energy at small adsorption energy and reaches one for a finite adsorption energy. The effect of an external force is also briefly discussed. |
Single Nodular Opacity of Granulomatous Pneumocystis Jirovecii Pneumonia in an Asymptomatic Lymphoma Patient | The radiologic findings of a single nodule from Pneumocystis jirovecii pneumonia (PJP) have been rarely reported. We described a case of granulomatous PJP manifesting as a solitary pulmonary nodule with a halo sign in a 69-year-old woman with diffuse large B cell lymphoma during chemotherapy. The radiologic appearance of the patient suggested an infectious lesion such as angioinvasive pulmonary aspergillosis or lymphoma involvement of the lung; however, clinical manifestations were not compatible with the diseases. The nodule was confirmed as granulomatous PJP by video-assisted thoracoscopic surgery biopsy. |
UNSTEADY THREE-DIMENSIONAL NATURAL CONVECTION OF WATER COOLED INSIDE A CUBIC ENCLOSURE | Three-dimensional unsteady natural convection of cooling water inside a cubical cavity at Ra = 105 is investigated. The finite-volume method with the SIMPLE algorithm is used to solve the nonlinear coupled continuity, momentum, and energy equations. All physical water properties—density, viscosity, thermal conductivity, and specific heat—are allowed to change with temperature. The numerical results for the 3-D geometry show that the side effects are relevant in fluid mechanics and in heat transfer, with larger differences than with the 2-D predictions in the region where the density anomaly of water is important. |

The system adopts the progressive reason, combined with the case-based reasoning and the rule-based reasoning. The practical application shows that the system has improved the judging and decision-making level of the dispatchers. |
AN INTEGRATED SPATIAL INDEXING OF HUGE POINT IMAGE MODEL | In order to manage point image model easier and build the point cloud model on the basis of the need and improve the query efficiency, a 2D&3D integrated spatial index of large point image model is proposed in this paper.

Self-localization of quantum charge on the inner surface of metal | The well-known model of a plasmaron was applied to describe the states of quantum charges on a metallic surface. A theory of a surface self-localized axial plasmaron was suggested. The theory considers the plasmaron as a structure that results from interactions between both axial plasmon and an electron adjacent to the inner side of a metal surface with an energy close to the Fermi level. The proposed model is very important for physicochemical and electrochemical applications, since it determines adequately the role of the attractor factor of a metal surface (a Fermi sea) determining the affinity of metal to quantum charge. It is suggested that the phenomena of self-localization of an electron (hole) by a plasmon attractor is behind the physics of chemisorption processes on metals and plays an important role in understanding the nature of electrochemical effects on metal electrodes. |
Mr. Tompkins in Java: Interactive Lorentz transformations | This paper describes a simple applet for illustrating Lorentz transformations. The user specifies stationary and moving objects and light pulses, and sees animations of two reference frames. Even with minimal graphics (the objects are colored dots and the light flashes are expanding circles), such animations can make the concepts of redshift, length contraction, time dilation, and non-simultaneity more intuitive than traditional spacetime diagrams. |
Process and mechanism of fracture in a pipeline material in chloride and sulphide environments | Abstract The kinetics and mechanism of subcritical cracking in a hot rolled microalloyed steel have been investigated in presence of 3.5% NaCl and H2S impregnated acetic acid solutions. The J-integral parameter is used to determine the threshold JIscc and terminal JIf values analogus to KIscc and KIf. H2S environment appears to be more aggressive than the NaCl medium where considerable amount of energy dissipation occurs during the cracking process. Joining of fine cracks, resulting from blistering of pits/voids is responsible for subcritical cracking under H2S medium, while the process of environmental cracking under NaCl medium occurs mainly by the growth of pits to link up in the direction of stressing. |
Monthly Steer and Heifer Supply | The manner in which producers form price expectations is often a destabilizing influence on observed prices. Recent price trends are extrapolated, leading to delayed or accelerated marketings which reinforce the existing price trend. An analysis of monthly steer and heifer slaughter yields this conclusion. The theoretical framework links capital theory with the hypothesis concerning extrapolation of price trends. Apparent conflicts in previous studies of the short-term response of slaughter to prices are clarified and partially resolved by the theoretical and empirical results. |

SOLVING DIFFERENCE EQUATIONS BY FORWARD DIFFERENCE OPERATOR METHOD | In this paper a forward difference operator method was used to solve a set of difference equations. We also find the particular solution of the nonhomogeneous difference equations with constant coefficients. In this case, a new operator call the forward difference operator ∆r,s, defined as ∆r,s yn = r yn+1 - s yn, was introduced. Some of the properties of this new operator were also investigated. |
On the within-population relationship between dietary habits and serum lipid levels in Belgium | In a Belgian population group of 15 954 male and 2116 female subjects, an epidemiological survey has been conducted to investigate the relationship between dietary fat intake and serum total and HDL-cholesterol. The study has established, both in men and in women, a significant positive relationship between serum total cholesterol and the dietary intake of saturated fat and a significant positive relationship between serum total cholesterol and the dietary intake of saturated fat and a significant negative one between serum total cholesterol and the intake of polyunsaturated fat and the P/S-ration of the diet. At equal levels of consumption, polyunsaturated fat has a decreasing effect on serum total cholesterol which is about half the increasing effect due to saturated fat. Polyunsaturated fat and the P/S-ratio decrease the HDL-cholesterol value but only with borderline significance. The present study demonstrates the importance of dietary fat as a determinant of the serum lipid level within a Population. |

Updated best-estimate LOCA radiation signature. Final report | Proper radiation qualification of nuclear power plant equipment depends upon estimating the radiation environment in which equipment will be expected to perform. Over the past several years, the Qualification Testing Evaluation (QTE) Program being conducted by Sandia Laboratories for the U.S. Nuclear Regulatory Commission has been addressing the problem of radiation source term definition. As part of the QTE Program, IRT Corporation has conducted studies (Refs. 1-4) focusing on expected source terms resulting from the hypothesized loss-of-coolant accident (LOCA). The objective of the study was to review research conducted since the last study and make modifications and improvements in the 'best-estimate' LOCA radiation signature. This report contains a review of the fission product source terms literature since 1978, changes made in the 'best-estimate' source term, comparisons with the previous 'best-estimate' source term in Ref. 4, and suggestions for future work. |

Effects of colchicine on risk of cardiovascular events and mortality among patients with gout: the effect of index date selection? | We read with great interest the study by Solomon et al 1 regarding the effect of colchicine on risk of cardiovascular (CV) events and all-cause mortality. In their study, they report a marked reduction in the number of CV events and all-cause mortality with the use of colchicine when compared with a reference group not using this drug. Sensitivity analyses mimicking an intention to treat approach showed similar results. Interestingly, no clear gradient of effect according to duration of use was found. The striking … |
La transmission de la violence dans l’institution médico-sociale | The maintenance of the teenage population mental retardation within this system, perversely, is facilitated by function of the institution, and in particular by the culture and the transmission of institutional violence through which it is regulated. This research proposes to demonstrate how the proximity and heterogeneity of the inmates, the complexity of the mission entrusted to the institution, the sanction of institutionalising a child, and the working conditions of the staff, all have resulted in a combination which is complex, pathogenic and intractable. |
Effect of Hip Protectors and Body Mass Index on Pressure Distribution During a Fall on the Hip | Hip fractures are a major health problem among the elderly, and 90% of fractures are caused by falls. Wearable hip protectors (Parker et al., 2006) represent a promising strategy for attenuating and redistributing the force applied to the hip region, and thereby reducing the risk for hip fracture during a fall. However, the protective effect of hip protectors should depend on the direction of the fall, and the amount of baseline soft tissue padding over the hip. In the current study, we tested these hypotheses through safe falling experiments in young adults. |
