Demand is growing in technological lines of the oil and gas industry for stop-control valves that provide the required throughput characteristic at the pressure drop of 25 MPa or more. Compared to valves, the gate valves have the lower resistance coefficient in the open position. Slide stop-control devices are widely used as the stop-control valves. The most important problems that arise in designing such devices include determination of the hydraulic and cavitation characteristics and of the specific pressure at the gate. Internal bypass introduction in the control valves makes it possible to increase regulation accuracy at the high pressure drops, and using it in the gate valves to reduce forces in displacement of the stop-control elements and specific pressure at the gate when opening/closing, as well as to determine the point of the cavitation bubbles collapse in the flow. A method for calculating hydraulic characteristics of the bypass and a method for determining its throughput characteristics on the basis of computational and theoretical research using the modern engineering analysis system are proposed.


Environmental news is rarely positive. Habitats continue to be destroyed worldwide and species diversity continues to decline at an alarming rate. And yet species are being saved from extinction and botanic gardens are playing a key role in this task. Adding up the conservation actions of individual botanic gardens provides a good story and one that should be told more widely.


An automatic method of cutting from the sheet table mounted on the spacer frame of insulating glass unit begins by identifying a specific position and orientation in the sheet cutting table, and the robot moves to the sheet pickup apparatus for the said sheet corresponding to the identified position. The specific sheet from an edge of the table is raised starting at the corner portion of the sheet near the pickup suction machine in the main vacuum suction device. In particular, the pickup device may have a substantially flat platen, said platen having a channel group is coupled to a vacuum source. Once completely picked up by vacuum suction the sheet, the sheet will be placed on the table top surface is inclined, the inclination of the platen table may be only reversed. The station (or platen) is inclined to the corner portion of the sheet abuts against a physical barrier. Once known position and orientation of the sheet, the sheet will be oriented to correspond with the frame, and attached to the frame.


The article presents the results of studying the characteristics of the workshop design process of the actively developing science-intensive areas that have a high degree of variability
of the technologies used and the requirements for the skills of specialists in the industry. The approach to organizing the automated design process for the daily workshops on the basis of expert opinions of the trainees' employers has been proposed. The approach implements the model of pedagogical design ADDIE at the stages of analysis and design and involves four stages: calculating the degree of trust in experts, selecting learning tasks for the discipline, developing the structure of the workshop taking into account the relevance of each learning task of the discipline for a particular training profile, and calculating the complexity and assessments (points) tasks for each profile. According to the introduced rule of assessment, calculation of weight coefficients for each of the learning tasks and the rule of ranking the selected tasks are arranged in the optimal order for studying, and an individual learning path for each professional profile is formed. The methods and algorithms described can be used to develop information systems for designing a workshop.
A software package for instrumental and information support has been developed. It implements all the calculation and ranking functions and appears a system for the workshop automated design. Using this system and the proposed approach, the structure and the list of learning tasks of the workshop on the discipline "Embedded Systems" are formed. The proposed solutions allow an iterative assessment of the relevance of learning tasks of the discipline taking into account the expert opinions of potential employers and improve the real model of training specialists due to the high practical importance of the workshop and, as a result, to the high motivation of the trainees to obtain professional practical skills that are in demand in the labor market.


By adding the right constraints and pushing the design to the right places, optical designers can quickly turn a difficult part into a viable solution.

Manganous oxide (MnO) whiskers have been grown by heating manganous chloride (MnCl2) in a stream of hydrogen for 1½ h at about 900°C. These whiskers have very unusual growth structures consisting of spirals, twists, and prisms. MnO whiskers have a high degree of structural perfection as judged by their stability in air. Unlike ordinary crystals of MnO, these whiskers do not absorb oxygen unless they are fractured. It is proposed that MnCl2 diffuses to the whisker growth sites where it reacts with water vapor to form a higher oxide of manganese which is subsequently reduced by the hydrogen to MnO. The MnO then migrates to growth steps provided by the intersections of axial screw dislocations with the surfaces at the tips of the growing whiskers.

Preface The field of sparse and redundant representations has evolved tremendously over the last decade or so. In this short series of lectures, we intend to cover this progress through its various aspects: theoretical claims, numerical problems (and solutions), and lastly, applications, focusing on tasks in image processing. Our story begins with a search for a proper model, and of ways to use it. We are surrounded by huge masses of data, coming from various sources, such as voice signals, still images, radar images, CT images, traffic data and heart signals just to name a few. Despite their diversity, these sources of data all have something in common: each and everyone of these signals has some kind of internal structure, which we wish to exploit for processing it better. Consider the simplest problem of removing noise from data. Given a set of noisy samples (e.g., value as a function of time), we wish to recover the true (noise-free) samples with as high accuracy as possible. Suppose that we know the exact statistical characteristics of the noise. Could we perform denoising of the given data? The answer is negative: Without knowing anything about the properties of the signal in mind, this is an impossible task. However, if we could assume, for example, that the signal is piecewise-linear, the noise removal task becomes feasible. The same can be said for almost any data processing problem, such as de-blurring, super-resolution, inpainting, compression, anomaly detection, detection, recognition, and more-relying on a good model is in the base of any useful solution. When approaching a problem in image processing, there is a wide range of models to choose from, such as Principal Component Analysis (PCA), Anisotropic diffusions, Markov Random Fields, Total-Variation, Besov spaces and many more. There are two important (and sometime somewhat contradictory) requirements for a model to be useful. On one hand, it should be reliable, in the sense that it should be able to represent the data well. On the other hand, it has to be simple enough to be applied in practice to the various tasks at hand. A simple example of a model used in a common task can be found in the JPEG algorithm. At its core, this algorithm relies on the claim that when transforming patches of 8×8 pixels in a typical image using the Discrete Cosine Transform (DCT), only the top-left (low frequency) components are dominant, while …


The imaging speed is a bottleneck for magnetic resonance imaging( MRI) since it appears. To alleviate this difficulty,a novel graph regularized sparse coding method for highly undersampled MRI reconstruction( GSCMRI) was proposed. The graph regularized sparse coding showed the potential in maintaining the geometrical information of the data. In this study, it was incorporated with two-level Bregman iterative procedure that updated the data term in outer-level and learned dictionary in innerlevel. Moreover,the graph regularized sparse coding and simple dictionary updating stages derived by the inner minimization made the proposed algorithm converge in few iterations, meanwhile achieving superior reconstruction performance. Extensive experimental results have demonstrated GSCMRI can consistently recover both real-valued MR images and complex-valued MR data efficiently,and outperform the current state-of-the-art approaches in terms of higher PSNR and lower HFEN values.


A new law administration practice statement will give trustees some comfort that the ATO will not issue an assessment outside the normal two-/four-year periods.


Levothyroxine (T4) replacement need in adults with primary hypothyroidism has recently been reported to fall with age. Previous studies have demonstrated that the resting metabolic rate falls with age in euthyroid adults and that this fall is proportional to a reduction in lean body mass (LBM). Since LBM is correlated also with 24‐hour energy expenditure, this study examined the possibility that LBM might be an accurate predictor of T4 requirement. Seventy‐five hypothyroid adults receiving full replacement therapy, ranging in age from 24 to 88 years, were studied retrospectively. Lean body mass was found to be a better predictor of T4 requirement than age or weight for the entire group as well as for subgroups of men and women 51 years old and older. The age‐related reduction in LBM may be responsible for the reported decrease in the rate of fractional thyroxine degradation with age.


Spherical caps are widely used to produce efficiently focused ultrasonic fields. Due to the curvature of the source surface, no exact analytical expression of the radiated field is known. The approximate model of Williams and O'Neil [J. Acoust. Soc. Am. 17, 219‐227 (1946); 21, 516–526 (1949)] is expected to be limited to high‐frequency, slightly focusing sources. In order to determine more precisely the limits of that model, and to dispose of an efficient tool for describing precisely the focused field, a new numerical method is presented. It is based on two expansions of the pressure field into spherical harmonics in two conveniently chosen domains. The expansions are then matched. Validity of the method is assessed by making a comparison with the exact analytical solution for the planar case. Then, the sound field radiated by a sharply focusing radiator is investigated. Comparison of the results of the numerical procedure with the approximate model indicates a much wider domain of validity of the model than generally thought. More precise conditions for the applicability of the model are derived, that follows from simple considerations of geometrical acoustics.

New discoveries show that very small theropod tracks (cf. Wildeichnus) are abundant in the upper part of the Moab Member, recently assigned to the Curtis Formation (formerly considered part of the Entrada Formation) in the Mid-?Late Jurassic of eastern Utah. The tracks represent a distinct small-theropod ichnofacies associated with eolian dune deposits that is easily differentiated from the water-lain beds of the overlying Megalosauripus-Therangospodus ichnofacies, which comprises the single-surface Moab megatracksite. Pterosaur track assemblages, representing the Pteriachnus ichnofacies, are found a few meters above the megatracksite surface in the upper tongue of the Summerville Formation. The small theropod ichnofacies is reminiscent of other early Mesozoic dune facies ichnofaunas from the Wingate and Navajo formations (Late Triassic and Early Jurassic) where small theropod tracks occur in association with other small tetrapod footprints. All such examples evidently represent a recurrent dune facies ecosystem dominated by diminutive vertebrates. Because the small theropod ichnofacies is one of three ichnofacies found in a thin stratigraphic sequence (<20 m) that contains no body fossils, it is clear that vertebrate tracks play an important role in providing insight into the paleoecology of units previously considered devoid of any useful fossil evidence. The three successive ichnofacies represent a transgressive transition from sand dunes, through sandy shoreline to shallow marine environments, each with its quite distinct vertebrate fauna.


This study was carried out to investigate the characteristics of root growth features in Kentucky bluegrass sod(KBS) and creeping bentgrass roll sod(BGS) transplanted in summer(August 9) and fall(September 19) respectively. Hydroponic system was also used to observe rooting development in the study. root development differed in KBS by transplanting time. It reached to more than 5㎝ after 100 days in summer and 50 days in fall. However, BGS's root grew over 6㎝ after 40 days, regardless of the season. There was no significant differences in BGS, regardless of any cutting treatment. In the case of KBS, it was best with sod cutted with 0.5㎝ deep and 1.5㎝ long. But it grew beyond 5 ㎝ in root growth in any treatment after 40 days in transplanting. In a hydroponic study, BGS produced root over 100㎝ for 80 days through a summer season. However, the root of KBS did only grow in condition of below 20℃. These results indicated that root growth characteristics were variable in BGS and KBS. It was considered that rooting development of BGS might be improved with sufficient irrigation in summer, and KBS grows well in lower temperature of 10~18℃, as compared with BGS. As to establishing the lawn with a sodding method, it should be careful in transplanting time, especially KBS.


Significance Parkinson's disease, Lewy body dementia, and other synucleinopathies are characterized by the accumulation of abnormally aggregated α-synuclein (α-syn) protein, which is the principal component of Lewy bodies. Immunotherapeutic approaches aimed at halting the propagation of both central and peripheral extracellular α-syn aggregates may be a promising therapeutic avenue for synucleinopathies. Our study demonstrates that natural killer (NK) cells act as efficient scavengers of abnormal α-syn aggregates without becoming aberrantly activated. We demonstrate that systemic depletion of NK cells significantly exacerbates synuclein pathology. Overall, our results provide strong evidence for a protective role of NK cells in synuclein-related neurodegenerative diseases. The pathological hallmark of synucleinopathies, including Lewy body dementia and Parkinson's disease (PD), is the presence of Lewy bodies, which are primarily composed of intracellular inclusions of misfolded α-synuclein (α-syn) among other proteins. α-Syn is found in extracellular biological fluids in PD patients and has been implicated in modulating immune responses in the central nervous system (CNS) and the periphery. Natural killer (NK) cells are innate effector lymphocytes that are present in the CNS in homeostatic and pathological conditions. NK cell numbers are increased in the blood of PD patients and their activity is associated with disease severity; however, the role of NK cells in the context of α-synucleinopathies has never been explored. Here, we show that human NK cells can efficiently internalize and degrade α-syn aggregates via the endosomal/lysosomal pathway. We demonstrate that α-syn aggregates attenuate NK cell cytotoxicity in a dose-dependent manner and decrease the release of the proinflammatory cytokine, IFN-γ. To address the role of NK cells in PD pathogenesis, NK cell function was investigated in a preformed fibril α-syn–induced mouse PD model. Our studies demonstrate that in vivo depletion of NK cells in a preclinical mouse PD model resulted in exacerbated motor deficits and increased phosphorylated α-syn deposits. Collectively, our data provide a role of NK cells in modulating synuclein pathology and motor symptoms in a preclinical mouse model of PD, which could be developed into a therapeutic for PD and other synucleinopathies.


In this contribution, ellipsoidal and hexagonal prism representative volume element (RVE) which characterize the steel fiber reinforced high performance concrete (HPC) along a preferred fiber direction are constructed and analyzed numerically. A virtual experiment is simulated using a microscopic boundary value problem based on two different RVEs. The suitable mechanical and periodic boundary conditions are applied on each RVE at the microscale. The homogenized macroscopic quantities are computed using their microscopic counterparts. The microscopic response of ellipsoidal and hexagonal prism RVE are simulated and the macroscopic behavior of steel fiber reinforced HPC is analyzed.


Ion beam instabilities on a wide ribbon beam which cross-section is 150 cm × 10 cm are discussed. At low energy conditions, we detected two kinds of instabilities on the ion beam extracted from BF3 plasmas. One kind of the instabilities is that onset of the instability is dependent on the extraction current from the ion source. This instability occurred when the extraction current exceeded 300 - 350 mA at the energy of 15keV. Another is that the onset is dependent on the BF2+ beam current. The BF2+ beam current became unstable when it exceeded about 20 μA/cm2 at 15keV. Energy dependence of these instabilities is also discussed.


This chapter describes the fundamentals of term-structure modeling from the point of view of Arbitrage Pricing Theory. The main question that we address is how to construct a risk-neutral probability measure for the evolution of the the term-structure of interest rates. The term-structure is represented by the collection of discount factors (1) P T t = E P t n e ; R T t r s ds o T > t or, equivalently, b y the instantaneous forward rates (2) f(t T) = lim t ! 0


Quality is the major differentiator in an increasingly competitive and fast growing business environment in Ireland. This paper focuses on the degree to which quality initiatives have been developed in Irish organisations. Based on two major large scale national surveys of manufacturing and service organisations, the paper shows the scale of adoption of total quality concepts and the degree to which total quality management (TQM) is associated with standards, strategic planning, teamworking, employee and customer satisfaction, use of quality tools/techniques, benchmarking and relationships with suppliers. Some comparisons are made between the two surveys which suggest that service organisations have been slower than manufacturing companies to adopt total quality management in Ireland. However, the study points to a heightening of awareness about TQM among service,as well as manufacturing, organisations in Ireland.


Objective To investigate the prevalent rate of anti-HAV IgG in normal adults over 20 years old in Guangzhou in 2008. Methods 500 sera were collected from normal adults for a routine medical examination in Nanfang Hospital in 2008. The Architect HAVAb-IgG (chemiluminescence method) was used for detection of anti-HAV IgG in serum,and the prevalent rates of anti-HAV IgG in the different age groups were evaluated. Results The prevalent rate of anti-HAV IgG in the population of age 20 in Guangzhou in 2008 was 72.2% (361 / 500),in which 73.2% (230 / 314) for male,and 70.4%(131 / 186) for female. The prevalent rates of 20-,30-,40-,50-and ≥60 years age groups were 52.8% (56/106),52.5% (63/120),82.5% (94/114),89.8% (88/98) and 96.8% (60 / 62),respectively,with a trend of increasing with age. Conclusion At present,the prevalent rate of anti-HAV IgG is relatively low among the population age from 20 to 39 years old in Guangzhou. HAV vaccination should be recommended for the young adults susceptible to HAV infection.


The paper summarizes how effective ERP implementation help to foster the organizational culture and provides exceptional benefits to the business of manufacturing plants that mass-produce with little changes through better implementation plan. Industries have invested considerable resources in the implementation of Enterprise Resource Planning (ERP) systems. The results initially expected rarely have been reached. Information in large organizations is often spread across numerous home grown computer systems, housed in different functions or organizational units. While each 'information islands' can ably support a specific business activity, enterprise –wide performance is hampered by the lack of integrated information. Further the maintenance of these systems can result in substantial costs. Hence, this paper provides the complete roadmap of Enterprise Resource Planning implementation for Manufacturing Industries and helps in its successful implementation.


As consequence of rapid urbanization,urban wetlands in China are suffering rapid loss and degradation. Taking Shanghai's wetland management and conservation as an example,it's argued that the fundamental reasons dwell in four aspects: the high demand of construction land driven by urban sprawl,the lack of legal base for wetland protection,imperfect wetland management system and information system,and the absence of market mechanism and public participation. It is suggested that we enhance the national wetland conservation institutions starting from the local legislation,change one-resource based management system to integrated management system,and provide opportunities for market forces and encourage public participation.

To obtain a basic knowledge of the cadmium resistance of the Fagopyrum crops (common buckwheat [Fagopyrum esculentum] and Tartary buckwheat [Fagopyrum tataricum]), the effect of the germination rate and seminal root growth were examined by using the seed-pack growth pouch that filled the cadmium chloride solution. Paddy rice, upland rice (Oryza sativa), sorghum (Sorghum bicolor), rape (Brassica napus), and leaf mustard (Brassica juncea) were used as comparison crops. There was no effect of 100 ppm or less cadmium on the germination rate except with paddy rice, but except for leaf mustard, the main root elongation was inhibited. The order in which cadmium resistance was regarded : paddy rice, upland rice, sorghum, common buckwheat, Tartary buckwheat, rapeseed, and leaf mustard. In 15 varieties of common buckwheat and 3 varieties of Tartary buckwheat, there was the continuous varietal differences of cadmium resistance. These results show that it may be possible to select cadmium resistance lines. It is also expected that buckwheat crops will become new materials for phytoremediation.


The aim of the research was to identify the most efficient cluster level and crop harvesting period (day) for tomato seed production, as well as to find out which seed breeding options will ensure higher quality indicators. The study objects were mid-early ripening tomato variety "Anahit 351" and mid-ripening varieties "Lia" and "Eraz".
Experimental results showed that tomato seeds taken from the fruit of second cluster after 10 days of ripening have provided highest seed weight, high germinability and germination energy meanwhile ensuring high productivity.


Decision trees are among the most popular pattern types in data mining due to their intuitive representation. However, little attention has been given on the definition of measures of semantic similarity between decision trees. In this work, we present a general framework for similarity estimation that includes as special cases the estimation of semantic similarity between decision trees, as well as various forms of similarity estimation on classification datasets with respect to different probability distributions defined over the attribute-class space of the datasets. The similarity estimation is based on the partitions induced by the decision trees on the attribute space of the datasets. We use the proposed framework in order to estimate the semantic similarity of decision trees induced from different subsamples of classification datasets; we evaluate its performance with respect to the empirical semantic similarity, which we estimate on the basis of independent hold-out test sets. The availability of similarity measures on decision trees opens a wide range of possibilities for meta-analysis and meta-mining of the data mining results.


In this paper, we emphasize and discuss some attacks on wireless sensor network which are of crucial significance to the performance and existence of it. The wireless sensor networks are resource constrained, more particularly power and memory. Attacks such as Sybil, HELLO, Wormhole and Sinkhole basically target routing of packets and degrade the throughput and performance of network by draining out power and memory. This paper underlines and describes the need of robust routing protocols to secure the wireless sensor network against such attacks. A comprehensive study of existing protocols such as Directed Diffusion, TinyOS beaconing, Geographic and Rumor routings is been presented here along with future research scope.


The aim of this study is to evaluate the Late Bronze Age hoard from Nagydobsza (Hungary, Co. Baranya) from the perspective of the typo-chronological method and macroscopic examination. The Nagydobsza hoard consists of 263 artefacts (total weight: 19.053 g) which can be classified into five groups: weapons, tools, clothing parts, semi-finished products and metal working debris. According to the macroscopic investigation, the objects can be divided into different technological groups, such as finished products (in certain cases with traces of usage), unrefined products, "defected" objects, semi-finished products and metal working debris. Another important characteristic of the hoard is its highly fragmentary state, which is mostlikely the result of an intentional, non-votive partitioning of the objects. Although the parallels of the hoard can be dated between the Ha A1 and Ha B1 periods, it also shows strong relations to the "Gyermely type" hoards. Based on typological arguments, the assemblage was most likely deposited in the Ha B1.


A depression extends from a main surface of the substrate to the inside of said substrate and has an upper area and an adjacent lower area. A cross-section of the upper area, parallel to the main surface, is provided with at least one corner. A cross-section of the lower area, parallel to the main surface, matches the cross-section of the upper area, particularly in the vicinity the upper area, with the following difference: each corner is rounded, whereby the cross section of the lower area is smaller than the cross-section of the upper area. In order to produce the indentation, the upper area is provided with an auxiliary spacer that is rounded by isotropic etching. The lower area is produced by selectively etching the substrate to form an auxiliary spacer.


for an Invited Paper for the MAR09 Meeting of The American Physical Society Bose-Einstein Condensation of Microcavity Polaritons in Harmonic Traps DAVID SNOKE, Department of Physics and Astronomy, University of Pittsburgh Polaritons in microcavities are a two-dimensional, weakly interacting boson gas, and their spatial distribution, momentum distribution, coherence properties, and excitation spectrum can all be observed. In several recent experiments, these observations are consistent with the interpretation of a quasiequilibrium Bose condensate of polaritons. In our experiments, we use a special stress geometry to create a harmonic potential for the polaritons in the plane of their motion, which is analogous to the traps used in experiments on BEC of cold atoms. Among other effects, we observe coherent light emission from the polariton condensate. Two questions arise: 1) Since the system emits coherent light, how can we distinguish it from a standard laser? 2) How do we distinguish it from some type of nonlinear amplification of the excitation light? In our experiments with a trapping potential, we can easily distinguish between these different effects. We demonstrate two transitions which occur in the same place in the same structure, one which is standard lasing and one which is polariton condensation. The quasiequilibrium polariton condensate in microcavities thus emerges as a new type of coherent light emitter.


A simplified flowpath analysis of a single-tube airbreathing pulse detonation engine is described. The configuration consists of a steady supersonic inlet, a large plenum, a valve, and a straight detonation tube (no exit nozzle). The interaction of the filling process with the detonation is studied, and it is shown how the flow in the plenum is coupled with the flow in the detonation tube. This coupling results in total pressure losses and pressure oscillations in the plenum caused by the unsteadiness of the flow. Moreover, the filling process generates a moving flow into which the detonation has to initiate and propagate. An analytical model is developed for predicting the flow and estimating performance based on an open-system control volume analysis and gasdynamics. The existing single-cycle impulse model is extended to include the effect of filling velocity on detonation tube impulse. Based on this, the engine thrust is found to be the sum of the contributions of detonation tube impulse, momentum, and pressure terms. Performance calculations for pulse detonation engines operating with stoichiometric hydrogen–air and JP10–air are presented and compared to the performance of the ideal ramjet over a range of Mach numbers.


Objective To analyze the clinical characteristics of intraspinal tumors in children and to summarize the experience in diagnosis and treatment. Methods The clinical data of 26 children with intraspinal tumors were retrospectively analyzed.

Conclusion There is a big difference between children and(adults) in clinical characteristics of intraspinal tumor.Early diagnosis,early treatment and postoperative combined therapy are key factors to improve prognosis.


Humans before birth have been equipped with various kinds of potential. If these potentials can be maintained and developed properly, humans will grow and develop perfectly and make them a resource to prosper this nature as God's purpose for creating humans themselves, namely as caliphs and servants of God on earth. In order to be able to continue or realize the caliphate and his servitude, humans in this family need to pay attention to certain things about their future children. In the pre-conception period, a man or woman must choose a future wife or husband from good people according to religious criteria, because the nature of a family will influence the character of the child to be born. In the pre-natal phase, a mother is advised to avoid bad deeds. Doing more good deeds such as attending recitation assemblies and reading the Koran is highly recommended. Besides that, pregnant women must also maintain food intake that meets food standards for pregnant women. This is important so that the mental and physical potential of the child to be born grows and develops perfectly. With the perfect growth and development of the two potentials, humans will be able to realize themselves as caliphs and servants of Allah on earth. The birth of weak, helpless children is something that must be avoided.


Cardisoma hirtipes appears from the species distribution to be dependent on fresh water. The ability of C. hirtipes to maintain ion and water balance and nitrogenous excretion in the absence of free water (water in which the crab can immerse itself) was assessed in the laboratory and in the field during both the wet and dry seasons. During enforced exposure to air for 9 days (only drinking water provided), the osmotic pressure and composition of both the haemolymph and urine remained constant, although the urine differed in composition to the haemolymph. The antennal gland reabsorbed Ca and Mg from the urine. The final excretory product (P) was dilute, containing only 10% of the concentration of ions measured in the haemolymph. Water loss to air was minimised by reduced P flow, but drinking was insufficient to prevent dehydration. Therefore, C. hirtipes might require periodic immersion to maintain long-term water balance. Nitrogen excretion to air was negligible compared to excretion to water, and after 9 days in air C. hirtipes excreted N at an elevated rate within the first 2 min of submersion. In the field, crabs restricted from access to water had urine and haemolymph osmotic pressure and composition similar to unrestricted, free-ranging crabs. The osmotic pressure was highest in crabs sampled in the wet season, although nitrogenous excretion rates were similar during the wet and dry season for both free-ranging and restricted crabs. The distribution of C. hirtipes is dependent on water availability, but under humid conditions water from drinking and food might balance short-term losses. The extent of terrestrial excursions by C. hirtipes is limited by dependency on water for nitrogen excretion. J. Exp. Zool. 279:537–548, 1997.© 1997 Wiley-Liss, Inc.


This unnecessary book lightly repackages three loosely related papers, all recently published in accessible places. There is a substantial overlap with the same author's earlier publications (reflected in the almost obsessive self-citation: a quick count reveals that N. cites himself, on average, more than 1.6 times per page); a lot of the material also appears in N.'s more substantial Poetry as Performance, published in the same year. When library budgets are so desperately overstretched, such gratuitous duplication seems questionable. N. can be stimulating, but there are problems in respect of clarity of communication, interpretation of evidence, and conduct of argument. Some miscellaneous observations may serve to illustrate my reservations. p. 3: N. contrasts his vision of philology with 'the singular strain of a monotone edict emanating from the unquestioned authority of accepted scholarship to which some would assign the title of philology': this absurd caricature fails to describe anything I can discern in the diversity of contemporary classical scholarship. pp. 6f: N. is troubled by scholars who use the terms 'right' and 'wrong' (preferring 'I agree' and 'I disagree'), and disparages 'criticisms that seem intended to displace or exclude results and views'. Yet a few pages later he refers approvingly to a 'vigorous criticism of a wide variety of misunderstandings', which provides a 'valuable . . . refutation' of some common assumptions (p. 26). To claim that a view has been 'refuted' is not simply to express disagreement: it implies that it has been disproven (i.e. that it is wrong). And what is N. seeking to do with those 'misunderstandings', if not to displace or exclude them? p. 17 n. 16: The concept of 'performance' is crucial to N.'s approach to Homer. It is a pity, therefore, that we are only alerted in passing to the possibility that the term is being used in a specialized sense ('My use of the term performance is not intended to convey any connotations of a stage presence, as it were, on the part of the performer'); still more so that the sense in which it is being used is given such a cursory and unilluminating explanation ('I have in mind rather the performative dimension of an utterance, as analysed from an anthropological perspective'). p. 103: N. suggests that the 'Peisistratean recension' is a myth—but one that goes back to the Peisistratids themselves, 'an instrument of propaganda for their dynasty'. This would be more convincing if there were any reason to believe that the myth is so old. Unfortunately, N.'s handling of the evidence fails to distinguish between traditions about (a) the introduction of the Homeric poems to Athens, (b) the establishment of rules for performance at the Panathenaea, (c) alterations to the text of the poems, and (d) the assembling (or re-assembling) of the poems from scattered parts. A 'Peisistratean recension' implies (c) and/or (d). But N. cites [Plato] Hipparchus, which only refers to (a) and (b), and Cicero, the earliest surviving reference to (d), indiscriminately as if they were testimony for the same story (p. 95). As a consequence, N. is unable to see the force of the theory that the 'Peisistratean recension' is a Hellenistic scholarly conjecture, or to provide an adequate response to it. pp. 103f.: Countering the view that 'the relative stability of the Homeric textual transmission . . . proves the archetypal existence of a written Homeric text', N. suggests that 'the alternative model of a relatively static phase in the evolution of the Homeric poems . . . can account for such textual stability'. But to speak of a relatively static phase in the poems' evolution does not 'account for' a period of textual stability; it just describes it in other terms. Tautology is not explanation. p. 146: At the end of a chapter on exemplary myths in Homer—are they sometimes ad hoc invention (Willcock) or do they 'stem from a rich, complex, and . . . subtle tradition' (N.)?—there is a paragraph on the etymology of the Latin word exemplum. I cannot conceive how this could


Mattawa, Ontario is located at the confluence of the Mattawa and Ottawa Rivers, east of North Bay on the Ontario-Quebec border. On the Quebec side of the river, high on top of the hill, stand three crosses. These crosses were first erected by Samuel De Champlain's party in 1614 to mark the place where the rivers met. From downstream on the Ottawa, the crosses could be seen from a great distance. Champlain's party were the first white people to see this place. Over the centuries, the crosses weathered and were replaced when necessary.


I miss restaurants and the incredible variety of places available to indulge in all manner of tastes and the shared experiences to energize me at the same time. Going to California a couple of times each year for Display Week activities was always a highlight of my year. First, we'd gather in January for the technical program committee meetings and then again in May for the main event. I'd see people I truly admire but only get to talk with a few times a year—people who would help me feel re‐energized with their incredible work and personal stories.


Teratogenesis, mutagenesis and carcinogenesis are among the most notable radiation effects in man. There is a continued need to find correlation between these biological responses and also to assess the effects or risks of the combined action of radiation and chemicals. Using the embryonic development of mice as a test system we are investigating the efficacy of low-dose irradiation and the possible influence of drugs on radiation-induced developmental anomalies (Michel and Fritz-Niggli, 1978). Embryonic cells and tissues are known to be particularly sensitive to radiation, drugs and stress and show some similarities to tumour cells with regard to metabolic functions such as cell proliferation, energy production and immunological response. Therefore data from the modification of radiation effects by drugs or chemicals in this experimental system may also be of practical relevance in the field of radiosensitization in radiotherapy. Moreover these data are important for risk estimations and radiological pro...


Background: Child's nutrition is an important factor in child's development, growth, and immunity particularly in the first two years of life. Lack of nutrition about complementary foods (quantity and quality) during this period also causes malnutrition. Methods: A quasi-experimental pre-post test design with single group research was aimed to study the effect of Local foods education on mother knowledge and anthropometry of child. Paired-T tests were used to analyze the effects of local foods education on mother knowledge and child anthropometry 6-21 months. Results: This study showed the mean differences of mother knowledge 10.91 (p=0.000), anthropometry of child weight-for-age 0.20 (±0.54) (p=0.037), height/length-for-age 0.01 (±0.23) (p=0.711), weight-for-height/length 0.31 (±.76) (p=0.025), head circumference-for-age 0.27(±.43) (p=0.001), and chest circumference-for-age 9.12(±10.11) (p=0.000). All variables had a significant effect after local foods education was provided (p<0.05), except height-for-age which showed p>0.05. Conclusion: The results revealed the effectiveness of the local food education to mothers with video recording and booklets. This intervention significantly increased mother's knowledge and anthropometry of child except height/length-for-age in the first month follow up.


Objective To design multi-adaptive filter based on radial basis function (MAF-RBF) for efficiently extracting somatosensory evoked potential (SEP) in real-time SEP monitoring.Methods With the optimization of important parameters that influence the performance of radial basis function neural network,the performance of extracting SEP was compared to that of a multi-adaptive filter (MAF),which developed from the combination of well-developed adaptive noise canceller and adaptive signal enhancer.Results In this simulation study,the outputs of MAF-RBF showed a similar waveform with SEP template signals,and a smoother waveform than the.output of MAF.Conclusion With appropriate parameter values,MAF-RBFNN is able to extract the latency and amplitude of SEP from the extremely noisy background rapidly and reliably without averaging.

In 5G scenarios, there are a large number of video signals that need to be processed. Multiobject tracking is one of the main directions in video signal processing. Data association is a very important link in tracking algorithms. Complexity and efficiency of association method have a direct impact on the performance of multiobject tracking. Breakthroughs have been made in data association methods based on deep learning, and the performance has been greatly improved compared with traditional methods. However, there is a lack of overviews about data association methods. Therefore, this article first analyzes characteristics and performance of three traditional data association methods and then focuses on data association methods based on deep learning, which is divided into different deep network structures: SOT methods, end-to-end methods, and Wasserstein metric methods. The performance of each tracking method is compared and analyzed. Finally, it summarizes the current common datasets and evaluation criteria for multiobject tracking and discusses challenges and development trends of data association technology and data association methods which ensure robust and real time need to be continuously improved.


In 1986 the accident at the nuclear reactor in Chernobyl in the former Soviet Union released large amounts of radioactivity into the atmosphere. Adjacent areas were heavily contaminated, while more distant regions were affected less. International committees concluded that valuable information on the effects of radiation might result from long term follow up of workers affected by the accident, many of whom received doses in the range of 250-1000 mSv. The committees also recommended that studies should be carried out of residents living within a 30 km radius of the reactor and of residents of substantially contaminated regions in Belarus, the Ukraine, and Russia, who may have received doses of 50-60 mSv. The scientific value of investigations in Europe and other parts of the former Soviet Union was questioned, however, because estimated exposures (<1 mSv) were believed to have been too low to cause a detectable excess of cases of cancer or genetic defects.1 For comparison, annual doses from natural background radiation are 1-2 mSv.2

Nevertheless, because of widespread concern among populations in Europe living in areas of low fallout, the International Agency for Research on Cancer organised the …

Abstract Analysis of the simulation of seasonal change by the GLAS model of the general circulation reveals deficiencies in the simulation of tropospheric temperature and of convective cloud cover. These interrelated deficiencies are due to a spurious doubling from January to July in the convective cloud cover of the Northern Hemisphere. The spurious doubling, in turn, is due to the oversensitivity of cumulus convection, in the GLAS model, to the specific humidity of the lower atmosphere. The oversensitivity is enhanced by a feedback mechanism which perpetuates the existence of deep, penetrative convective clouds at certain preferred locations. The cumulus parameterization scheme has been modified to more realistically relate the onset of cumulus convection to the relative humidity of the lower atmosphere. The modified parameterization has improved the simulation of tropospheric temperature, planetary albedo and convective cloud cover as well as their seasonal variations. Comparison of this experiment wit...


Teachers who leave the classroom to become principals often have difficulty adjusting to the new job responsibilities. A caring attitude may alleviate much of the stress associated with these administrative obligations. However, caring on the job is viewed as a weakness. This finding has led to the investigation of factors related to a caring administrator. The present research examines whether being a caring administrator provides growing opportunities outside of the classroom for teachers desiring a career change. The paper begins by reviewing literature on the definition of caring from various perspectives and on caring as it relates to school administration. Next, it investigates documented experiences of schools where caring exists. Finally, it concludes that effective schools nearly always have caring principals who are not afraid to give up power. Caring presents opportunities for administrators to grow as humans and for other people to grow from administrators' relationships with others. New administrators could feel more at ease with their new job responsibilities if they are perceived as caring. Recommendations include offering future administrators a graduate course on moral development; having professors of school leadership inform students of the aspect of caring and its implications on development; and informing current principals of the powers of caring.

Conclusions Tinnitus can be bothersome even without hyperacusis. The good correlation found in this study between the multiple-activity scale for hyperacusis (MASH) score and the overall annoyance of hyperacusis score supports the reliability of self-rating of hyperacusis. Objectives A prospective study was undertaken to investigate the relationships between hyperacusis and tinnitus and to determine whether hyperacusis can be rapidly controlled over time. Material and methods All tinnitus patients seen over a period of 16 months with surnames beginning with the letters A–L (n=249) were assessed during a structured interview using (i) a scale ranging from 0 to 10 for assessing the annoyance of tinnitus and the overall annoyance of hyperacusis and (ii) the newly introduced MASH. Results The annoyance of tinnitus was greater in females. The prevalence of hyperacusis was high (79%). The annoyance of hyperacusis varied. Patients were categorized into five groups according to the hyperacusis annoyance score, as follows: no hyperacusis; mild hyperacusis (≤3); moderate hyperacusis (3.1–5.0); substantial hyperacusis (5.1–7.0); and severe hyperacusis (≥7.1). Individuals with severe hyperacusis were younger than those in the other groups. The correlation between the annoyance of tinnitus and the annoyance of hyperacusis was poor (r=0.35). No audiometric difference was found between categories, whereas self-rated hearing deficiency increased with the annoyance of hyperacusis. A good correlation (r=0.89) was found between the overall annoyance of hyperacusis and the MASH score. Changes over time, assessed in 32 patients investigated at least 3 times, showed more frequent improvement in hyperacusis (63%) than tinnitus (47%).

The study explored the educational experiences of five people who are still in prison and one woman who has already finished her jail sentence. The analysis of the personal narratives of the informants allowed to understand, how the people who are in prison, twine different education strategies and opportunities, and based on them, re-signify their life experiences. Another result indicates that the pedagogical and educational practices in these scenarios give way to «alternative practices» which are built in harsh conditions of confinement and isolation. These results aim at contributing to understand the difference between «education for all» and «education for everyone» This last concept is taken from Skliar (2017) and Levinas (2002), and it is understood as education that embraces people who are in the edge of society and, thus, acknowledges the singularity of those who are in a condition of fragility.


The benefits of breastfeeding include optimized growth, neurological development and immune function in infants. However, sub‐optimal lactation occurs in ~15% of women and results in reduced milk volume, compromised milk composition or lactation failure. A mutation in the gene encoding ZnT4 (SLC30A4) is associated with sub‐optimal lactation in mice. These mice have smaller mammary glands (MG), decreased milk synthesis and ~35% less Zn secreted into milk. We hypothesized that ZnT4 plays a critical role in MG function. Genetic manipulation of ZnT4 abundance in mammary epithelial cells was positively correlated with Zn secretion. ZnT4 transported Zn into a labile Zn pool in the trans‐Golgi network (TGN) where it was made available for Zn‐dependent proteins. This was evidenced by ZnT4 attenuation which decreased carbonic anhydrase VI expression, and ZnT4 over‐expression which decreased galactosyltransferase activity. Additionally, ZnT4 exported Zn directly across the cell membrane. In summary, ZnT4 has a dual role involving 1) labile Zn accumulation in the TGN providing Zn to Zn‐dependent proteins; and 2) Zn transport across the cell membrane into milk. Our studies suggest that ZnT4 provides Zn to proteins critical for secretion and mammary gland function, thus understanding factors that regulate ZnT4 is important to increasing the incidence of lactation and improving the health of women and children.


Abstract Whiteite-(CaMnMn), CaMnMn2Al2[PO4]4(OH)2·8H2O, is a new hydrous phosphate of Ca, Mn and Al, which is closely related to both jahnsite-(CaMnMn) and the minerals of the whiteite group. It is monoclinic, P2/a, with a = 15.02(2), b = 6.95(1), c =10.13(3) Å, β = 111.6(1)º, V = 983.3(6) Å3, Z = 2 (from powder diffraction data) or a = 15.020(5), b = 6.959(2), c = 10.237(3) Å, β = 111.740(4)º, V = 984.3(5) Å3, Z = 2 (from single-crystal diffraction data). The mineral was found in the Hagendorf Süd granitic pegmatite (Germany) as small (up to 0.5 mm in size) crystals elongated on a and tabular on {010}. The crystals are either simply or polysynthetically twinned on {001}. They crystallize on the walls of voids within altered zwieselite crystals or form coronas (up to 1 mm in diameter) around cubic crystals of uraninite. The mineral is transparent, colourless to pale yellow (depending on Al-Fe3+ substitution), with a vitreous lustre and a white streak. The cleavage is perfect on {001}, the fracture is stepped and the Mohs hardness is 3½. In transmitted light, the mineral is colourless; dispersion was not observed. Whiteite-(CaMnMn) is biaxial (+), α = 1.589(2), β = 1.592(2), γ = 1.601(2) (589 nm), 2Vmeas = 60(10)º, 2Vcalc = 60.3º. The optical orientation is X = b, Z^a = 5º. The calculated and measured densities are Dcalc = 2.768 and Dmeas = 2.70(3) g cm-3, respectively. The mean chemical composition determined by electron microprobe is Na2O 0.53, MgO 0.88, Al2O3 11.66, P2O5 34.58, CaO 4.29, MnO 17.32, FeO 8.32, ZnO 2.60 wt.%, with H2O 19.50 wt.% (determined by the Penfield method), giving a total of 99.68 wt.%. The empirical formula calculated on the basis of four phosphorus atoms per formula unit, with ferric iron calculated to maintain charge balance, is (Ca0.63Zn0.26Na0.14)∑1.03(Mn0.60Fe0.402+)∑1.00(Mn1.40Fe0.372+Mg0.18Fe0.063+)∑2.01(Al1.88Fe0.123+)∑2.00[PO4]4(OH)2·7.89H2O. The simplified formula is CaMnMn2Al2[PO4]4(OH)2·8H2O. The mineral is easily soluble in 10% HCl at room temperature. The strongest X-ray powder-diffraction lines [listed as d in Å (I) (hkl)] are as follows: 9.443(65)(001), 5.596(25)(011), 4.929(80)(210), 4.719(47)(002), 3.494(46)(400), 2.7958(100)(022). The crystal structure of whiteite-(CaMnMn) was refined for a single crystal twinned on (001) to R1 = 0.068 on the basis of 5702 unique observed reflections. It is similar to the structures of other members of the whiteite group. The mineral is named for the chemical composition, in accordance with whiteitegroup nomenclature.


In commenting on the prescribing of hypnotic drugs a British physician bluntly states: &dquo;In my view we have been soft pedalling this aspect of prescribing long enough. I therefore propose to stick my neck out with the following pronouncements. Dependence on sleeping pills is a condition created and maintained by doctors. There is no condition known to medicine for which the sole treatment is a sleeping tablet every night for an indefinite period. Any doctor prescribing sleeping tablets in this way is giving unnecessary and possibly dangerous trearnlent alternatively he is giving inadequate treatment.&dquo; Lewis A (London Eng)BritMedJ3:463(Aug22)1970 .


Device for detecting that a motor vehicle is driving over a poor road surface, comprising: means for receiving signals pertaining to the rotational speed (omega ij) of the wheels which signals come from wheel rotational speed sensors for each wheel, and processing means (10, 11, 12, 13, 14, 15) for applying band-pass filtering to the signals received in order to isolate the low-frequency components representing the low-frequency noise present in the signals received so as to calculate the maximum value (omega max (f)) of the rotational speed signals thus filtered (omega ij (f)), representing the maximum value of the low-frequency noise for all the wheels, in order to threshold said maximum value with respect to a threshold (S1) and to detect the start of a situation of driving over a poor road surface having counted a pre-defined number of times that said maximum value (omega max (f)) crosses the threshold (S1) over a predetermined running distance and without the wheel slipping.


A method of magnetooptic effect analysis using an intracavity method is proposed. The method is particularly suitable for optical fibers. If the lineshape parameters are known for a given laser, the Faraday and Voigt effects can be conveniently evaluated by analyzing the magnetooptically-induced intensity-variation of the oscillation output. The method has been successfully examined in KRS-5 fiber and crystal using He-Ne 3.39 µm and CO2 lasers, and the experimental results agree well with the theoretical estimates. This paper also describes a method of determining the lineshape parameters if they are not known for a particular laser.

We have previously described the discovery of a unique set of infant records collected in Hertfordshire between 1911 and 1948. The historical data for births between 1911 and 1930 were linked to the NHS central register and showed that small size at birth and during infancy was associated with increased risk of cardiovascular mortality in men and women. These were the first studies based on individual data to suggest that adverse environmental influences acting in utero and during infancy might increase the risk of cardiovascular disease mortality in later life. Detailed physiological investigations of surviving men and women born in Hertfordshire between 1920 and 1930 and still living there in the early 1990s were subsequently conducted and allowed investigation of morbidity. Studies based on men and women resident in East Hertfordshire demonstrated that small size at birth and during infancy was associated with increased risk of developing coronary heart disease and type II diabetes mellitus, the metabolic syndrome and insulin resistance and osteoporosis. During the same time period (1994–95), 717 men and women resident in North Hertfordshire attended clinics where a wide range of markers of ageing were characterized. These clinics comprised the first follow-up of what will herein be referred to as the Hertfordshire Ageing Study (HAS). This study was the first to demonstrate that size in early life was associated with markers of ageing in older people. In 2004, mortality studies were extended to include the whole 1911–39 birth cohort and a second followup of the HAS cohort was carried out 10 years after the first one. Fieldwork for the second HAS follow-up was conducted at the same time as fieldwork for the larger Hertfordshire Cohort Study (HCS) which comprised 3000 younger men and women who were born in Hertfordshire between 1931 and 1939 and who still lived in the county. The HCS and HAS birth cohorts are completely distinct (with birth years ranging 1931–39 for HCS and 1920–30 for HAS) and have different, although related, research objectives. The principal objective of the HCS is to evaluate the interactions between the genome; the intra-uterine and early post-natal environment; and adult diet and lifestyle in the aetiology of chronic diseases in later life (cardiovascular disease, type II diabetes mellitus and obesity; osteoporosis, osteoarthritis and sarcopenia). The principal objective of the HAS (as described below) is to examine life course influences on healthy ageing, with sarcopenia, frailty, falls, physical performance and cognitive function as the principal outcomes of interest. The rest of this article describes the HAS in detail.


Based on reviews of the traditional theory of equality on distribution of income, this paper compares the equality on distribution of income and the equality on distribution of natural resources. It concludes that the equality on distribution of natural resources contains two meanings, i.e., extragenerational equality and intergenerational equality. The extragenerational equality is expounded at the angle of time. The extragenerational equality has three levels of meaning which are equality on regularity, equality on different generations, and the compensation. The paper analyses the devotions which the natural resources accounting theory gives to the extragenerational equality. It also uses a simple mode of transfer of wealth to judge the equality on distribution of natural resources. The intergenerational equality compares different countries and different groups in a country. The present conditions and the main reasons accountable for the inequality are analysed and the meanings of equality of different groups are discussed.


Comparing the respective structures of the correlators defining generalized and transverse momentum dependent parton distributions, one finds possible relations between these two objects. Although it looks like the relations found do not hold in general, we show that they can be established at least in simple spectator model calculations. In addition, we discuss these relations in the context of generalized transverse momentum dependent parton distributions.


We present recent developments in integrated four-wave mixing photon source arrays, produced via direct UV-writing in a silica-on-silicon substrate. These sources are of high purity and are mode-matched to optical fibre. Matching of the source arrays is demonstrated in initial results from quantum interference experiments, and efforts to further integrate these experiments are discussed. Introduction Significant advancements have recently been made in on-chip quantum optics experiments, highlighting the importance of integration in scaling to larger systems. Waveguide-integrated photon sources have been demonstrated in a variety of platforms, in the form of both single-photon emitters and photon-pair generation via non-linear processes. A key challenge in this area has been the difficulty of matching multiple sources without drastic reduction in count rates, particularly in an integrated format. In this work we demonstrate that birefringent-matched four-wave-mixing (FWM) sources in UVwritten silica-on-silicon waveguides possess sufficient uniformity for high quality quantum interference to be observed between photons emitted by independent guides in an array. This technology has previously been used in a range of twoand three-photon quantum circuits. Fabrication The UV-writing process utilized here involves a local refractive index increase induced in a photosensitive glass layer through absorption of a focused UV beam, translated across the substrate to inscribe a series of buried channel waveguides. The silica core and cladding layers were fabricated on a thermally oxidised silicon substrate via Flame Hydrolysis Deposition (FHD), the former of these being doped with germanium and boron for photosensitivity and the latter with boron and phosphorus. The birefringence of the resulting waveguides is dominated by the locked-in stress due to the different consolidation temperatures of these two FHD layers, which may be controlled by adjusting the dopant concentrations. This ability to tune the birefringence of the fabricated waveguides is invaluable since it allows the phase-matching to be tuned to place the signal and idler photons away from the Raman noise peak. This approach produces waveguides which are highly uniform in both birefringence and effective index over chip scales, and may be fabricated reproducibly.


ABSTRACT This article extends the knowledge in the area of empowerment of Chinese service employees by addressing the possible conceptual and methodological problems identified in Hui, Au, and Fock's (2004) study. The findings show that the lack of positive effect of discretionary empowerment on the job satisfaction and intention to comply with customer request of the Chinese subjects in Hui et al.'s (2004) study likely resulted from their use of hotel/hospitality management students as subjects. Without the confounding effect from the shared internalized values of the subjects, discretionary empowerment can have a positive effect on the job satisfaction and job behavior (e.g., intention to comply with customer request) of Chinese service employees. Furthermore, the findings show that explicit management support can further enhance the positive effect of discretionary empowerment on the job satisfaction and job behavior of Chinese service employees.

This paper discusses the concepts of innovation and transformation in relation to Library and Information Science Education (LISE). It also presents an overview of the history and current status of LISE in Nigeria. Different approaches to be adopted by LIS schools to ensure innovations and transformation in the training of information professionals are discussed. The paper reveals some challenges associated with LISE in Nigeria. These include lack of autonomy, lack of collaboration among LIS schools and other relevant departments. Others are inadequate and incompetent LIS teachers, and differences in LIS programme structure. It is advocated that the philosophy, goals and objectives of the programme; curriculum adopted and adapted; teaching methodology, state of infrastructural facilities are the cardinal points driving innovation and transformation in the profession. In conclusion, the paper notes that LIS schools in Nigeria and everywhere need to adopt relevant innovation and transformation approaches to equip students with the knowledge, skills, and competences needed to function effectively in any information environment. This paper recommends among others, the standardization of LIS curriculum, provision of technology-driven facilities, training and re-training of LIS teachers.


Data mining is widely applied to establish connections among the items in massive datasets nowadays. Association rule mining is one of the most popular methods to perform data mining, and a fundamental part of this is frequent itemset mining. Big-scale data are uploaded to the honest-but-curious cloud service provider (CSP). Therefore, it is imperative to protect the raw data from being obtained by the CSP and the third parties. Furthermore, because supermarket transactions are sparse, they are not suitable to be mined using the same methods used for most of the other data. The methods used for ordinary data will cost more computation power if they are applied on this special dataset. In this paper, we propose an efficient protocol to evaluate whether an itemset is frequent or not under the encrypted mining query on supermarket transactions. To improve the mining efficiency, we design a blocking algorithm. In this algorithm, we separate the encrypted transactions into blocks and only calculate bilinear pairings on ciphertexts of part blocks instead of all ciphertexts, which helps cut down the computation cost of the mining process. Finally, we evaluate the performance of our protocol by conducting theoretical analyses and simulator experiments in the aspects of computation cost, security, correctness, and running time. The results demonstrate that our protocol can output a correct mining result and clearly outperforms the previous solution in the aspect of efficiency under the same security level.

T here have been many exciting developments in rheumatology over the last two decades. A greater understanding of the functioning of the immune system in rheumatologic disorders has resulted in the development of targeted biologic therapies for patients.1 Biologic therapies represent a new kind of treatment for patients with a wide range of rheumatologic conditions such as rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and systemic lupus erythematosus (SLE). Traditional therapies such as methotrexate, salazopyrine, plaquenil and arava are still very much part of the patients prescribed program with methotrexate remaining the first line treatment used in the management of inflammatory arthritis. However the advances in molecular biology have led to an array of new treatment approaches to inflammatory arthritis.2


There always was much coherent sludge sediment in the blast furnace gas washing water pipe and the pipe became narrow in Hongfa iron making plant of Jiangsu Shagang group. Though analysis, we thought that this was mainly caused by the zinc ion in the gas washing water, much more suspended dust and fly ash adsorption. Through adding alkali and coagulant, the zinc ion and suspended dust were clearly reduced, and coherent sludge sediment descended from 4~5 cm thickness to 0.5 cm. The problem about coherent sludge sediment was basically solved.

The target image decision unit uses the decision result of the ground color decision unit to make a color decision of the target image based on the image data concerning the target image.


This study provides an investigation of the effect of human and social capital on advancement and self-efficacy of entrepreneurs through venture emergence. It ontributes to entrepreneurship research by covering all phases of the dynamic process and establishing novel outcome measures. Data was collected from 714 entrepreneurs in a random sample of 10,000 Danes and multiple regressions used to test 4 propositions. Human and social capital are generally found to positively effect self-efficacy and advancement of entrepreneurs, although professional network influence is insignificant and education only partly significant. The results should assist in increasing our understanding of venture emergence and help identify efficient policies and measures to lower entrepreneurial exit rates. INTRODUCTION Using data collected from randomly selected respondents, this study provides an investigation, based on entrepreneur network theory, of the effect of human and social capital on venture emergence and perceived entrepreneurial self-efficacy. Many studies in the field of entrepreneurship, borrowing from sociology and economics, have investigated the effects of human and social capital on entrepreneurial performance, such as growth in sales, employees or profit (1997; Lee, Lee et al. 2001; Westhead, Wright et al. 2001; Baum and Locke 2004). Some of this line of research has been criticized for the performance measures used (Robinson 1999; Witt 2004) and recommendations made for increased integration of outcome and process oriented research (Hoang and Antoncic 2003). Furthermore, limited attention has been paid to interaction effects between social and human capital (Coleman 1988; Davidsson and Honig 2003). Hoang and Antoncic (2003) call for increased integration between process and outcome oriented research by exploring how concepts from one research stream can usefully extend theoretical models in the other. They argue that outcome oriented research can become richer when combined with theoretical insights arising from research on network dynamics. With a dynamic longitudinal research design that covers the whole entrepreneurial process scholars can stop asking whether questions and start asking when and how questions. Furthermore, by using a longitudinal design it is possible to limit the "success" bias, where potential entrepreneurs that abandon their intentions will often be excluded from research. Sociologists have for many years investigated the interaction between human capital and social capital (Bourdieu 1986; Coleman 1988), while most entrepreneur scholars have been focused on the separate AGSE 2009


Laser‐evoked potentials (LEP) were assessed after peripheral nerve block of the lateral femoral cutaneous nerve (LFCN) in healthy volunteers from partially anesthetized skin areas to differentially stimulate mechano‐insensitive nociceptors.


Aiming at the problem of the live firing score evaluation in missile specialty, it analyses the characteristic of the training and built up the two-stage judgment model on the evaluation of progress by using the function in Matlab and fuzzy evaluation means. In addition, the different fuzzy models influence on the evaluation was analyses concretely in a certain discipline. It proved that the dominant-extrude-type fuzzy model could satisfy the demand of the evaluation and offered a sort of effective approach on evaluating the missile live firing discipline impersonally and thoroughly.


The fracture behavior of 110 tilt Cu-Bi tricrystals were studied and a contrast with that of Cu-Bi bicrystals was made. The results indicate that the triple junction affected the fracture behaviors of Cu-Bi tricrystals and made a grain boundary exhibit different fracture modes in bicrystal and tricrystal,The high internal stress near triple junction produced incompatibility of plastic deformation, as well as appearing of inhomogeneity of platic glide and lattice rotation. These are discussed by calculating stress field near triple junction.


The xenon anomalies trapped in meteorites and the Moon may have first been trapped in circumstellar grains formed in or outside of postexplosive stars. In that case, the initial solar nebula need not have contained most of their radioactive progenitors, and this would necessitate major revision of the history of solar system formation.


The purposeof the study was to investigate the dynamics of tumor volume change in different age groups and its relation to the clinical (sex, age, stage of disease, life expectancy) and morphological parameters (tumor localization, metastases to regional lymph nodes, tumor invasion depth, histological type and degree of differentiation).Material and methods.The data of 527 patients (men and women, age from 24 to 86 years) suffering from colorectal cancer who underwent primary resection of the tumor. Clinical data and protocols of pathologist were analyzed: clinical stage of the disease, tumor localization, life expectancy, macroscopic, microscopic description, diagnosis. Based on the data obtained from the gross description, the tumor volume was calculated.Results. The maximum incidence of colorectal cancer was observed in patients in the age group from 70 to 79 years, more than 90% of all patients are over 50 years old. The volume of the tumor in colorectal cancer varied significantly, but the dynamics of the increase of the average volume with age was not observed. Opposite, the largest neoplasms were found in the youngest patients.Conclusion. Obtained data shows that changes in the tumor volume in colorectal cancer is nonlinear. Indicators of tumor volume in different age groups show similar dynamics: the most common tumors are mediumsized, but the small and very large tumors are much less common, which can explain the low rates of detection of tumors of this localization in the early stages.


This authoritative and well presented book provides a very welcome analysis of the challenges related to shortages of financing for health — and the problems caused by a lack of financial protection and exclusion from social pooling mechanisms — that face poor agrarian and marginalized urban populations around the world. The book evolved from background work carried out for the WHO Commission on Macroeconomics and Health, with the mandate to "examine alternative approaches to domestic resources mobilization, risk protection against the cost of illness, and efficient use of resources by providers." It is divided into three parts, each of which consists of several chapters: part 1 discusses global and regional trends; part 2, country case studies; and part 3, expenditure gaps and development traps. One of the book's strengths is its systematic assessment of experiences with community financing for health care — and its critical evaluation of the pros and cons of community financing. It provides a useful typology of the multiplicity of community-based financing schemes that have been described in recent years, separating them into: 1) cost-sharing schemes, based on patient out-of-pocket payments managed with community involvement; 2) community prepayment plans, which pool resources to be used by members in case of illness; and 3) provider-based health insurance, where a hospital or other health-care provider forms the basis for a risk-sharing pool. All of these schemes share a "predominant role of collective action in raising, pooling, allocating or purchasing, and supervising the management of health-financing arrangements."

Donna con donna, femme à femme: so Pierre Brantôme designates the "art" of "lesbian ladies" at the close of the sixteenth century. "Woman with woman" certainly seems to suggest the desire of like for like, but Brantôme places man as the shadowy similitude beneath this same-sex coupling: Tribades "give themselves to other women in the very way that men do."2 What Marie-Jo Bonnet identifies as the first entry for "tribade" in a French dictionary echoes Brantôme's suggestion that "woman with woman" is somehow also "woman with man." In Richelet's dictionary of 1680, the tribade is one "who mates with another person of her sex and imitates a man."3 This understanding of the tribade as man-like carries us into, but does not carry us out of, the eighteenth century. In the larger project of which this essay forms a part, I argue that during the "Age of Enlightenment" new concerns that women might align themselves with other women become crucial in creating the ideology not simply of sexual but of heterosexual difference on which modern patriarchy grounds itself. Representations of female homoeroticism, which intensify dramatically during the late seventeenth and eighteenth centuries, perform complicated cultural work of both incitement and containment as European societies struggle with new challenges to male dominance.

Traffic safety enhancing systems can be divided, more or less, into two main categories: systems which are located along the driving route and systems which are included in the vehicle itself. The purpose of this study is to find out how common it is for Finns to have related technical devices in their cars. The research material was compiled in December 2008 by utilising the GallupChannel of TNS Gallup Oy. There were 1,191 people (age 18 or over) participating in the study. The number of car drivers in the study was 1,010 and of this number, 956 people answered the questions concerning technical devices. The average age of the participants was 48 years. No participant possessed all 18 devices featured in the study. Half of the participants had four devices or more. The most common device was airbag which was found in three out of every four participants' cars. Every third driver had an ESP (Electronic Stability Programme) in their car. The amount of various devices in the car correlated with the age of the vehicle. Newer cars are better equipped than older ones. In the study, the devices included in the car were assessed also in the context of the driver's perception of oneself as a driver. The more the driver assessed him/herself to have good driving skills, the more likely the chance that several devices were to be found in the car. Young drivers were more likely to drive old cars and possess less safety-enhancing devices than other drivers. About 73 percent of those drivers owning a mobile phone reported that they talk on the phone, at least occasionally, during the drive. Most commonly the phone was used while driving "occasionally, not daily" or "0-5 minutes a day". The share of those who reported using the phone "occasionally" has been on the climb since 2003. The share of those always using a hands-free device in the car had dropped to half in comparison to 2003 which was the year the new hands-free legislation took effect. In 2003, 62 percent of the participants stated that they always use a hands-free device during drive. One third of the participants had a navigator at their disposal. The navigator is felt to be clearly more useful in the car than a mobile phone. According to the participants of the study, acquiring additional devices for the car depends, most of all, on price and driving comfort. The participants were also asked: "Which device or technical system do you feel to be the most beneficial from the viewpoint of driving safety?" The most useful devices or systems were assessed to be ABS braking systems, seatbelts, ESP systems, airbags and cruise control. The least useful devices were deemed to be mobile phone or an attached hands-free device and car radio. In current safety thinking, the responsibility over safety is transferred, more and more, to the system planner/manager. The common safety principle is driver support. The driver support system balances, on one hand, between the benefits which the system is able to produce in surprising situations and, on the other hand, between the problems which may arise as the drivers are not as alert as they used to be under less sophisticated systems.

The incorporation of exotic germplasm into tropical breeding materials can broaden and diversify the genetic base of the tropical maize, and also adding more desirable alleles. For effective utilization of the exotic germplasm, choice of exotic source and efficient method of incorporation of exotic germplasm into tropical material is needed. This study was conducted to asses a genetic potential and the effectiveness of different types of exotic germplasm introduced from U.S. Corn Belt in combination with tropical breeding materials. The results of the study implied: commercial hybrid was the most promising source to improve performance of the tropical inbred lines followed by Non-BSSS inbred lines and BSSS "Iowa Stiff Stalk Synthetic" inbred lines. Semi-exotic population with 50% exotic showed significantly lower grain yield, earlier days to silking and anthesis, lower grain moisture content and higher leaf disease infection than 25 and 12.5 % exotic. On the other hand, no significant difference was observed between 25 and 12.5 % exotic. Semi-exotic pipulations with 25 and 12.5 % commercial exotic hybrid also showed grain yield higher than the corresponding tropical population but were not statistically different to the best check variety "Suwan 1".


Primary diagnosis was conducted based on clinical signs,microscopic changes in the lung and lymphnode tissue sections stained both HE and immunoperioxidase staining method.The Toxoplasma gondii was identified in the smears of ascites in ICR mice inoculated intraperitoneally with 1ml digested tissue sample(lung and lymph nodes) from the pigs.Toxoplasma gondii can be observed both in HE and immunoperioxidase stained tissue sections,however,only few fields can find Toxoplasma gondii pseudocysts or tachyzoites in HE sections,more browncolored Toxoplasma gondii tachyzoites or pseudocysts can be easily observed in more organ tissue sections stained by immunoperioxidase method.Immunoperioxidase staining method is a rapid diagnosing method for Toxoplasmosis in pigs.


An observatory has been created to evaluate the different economic regional effects of the Expressway A 71 which links the center of France, which was geographically enclosed, to Paris. Following categories were examined: microeconomic effects for the users; direct macroeconomic effects; and induced economic effects on population patterns, employment, agriculture, activities localization, industry, tourism and real estate.


We describe new features of FG that are designed to improve performance and extend the range of computations that fit into its framework. FG (short for framework generator) is a programming environment for parallel programs running on clusters. It was originally designed to mitigate latency in accessing data by running a program as a series of asynchronous stages that operate on buffers in a linear pipeline. To improve performance, FG now allows stages to be replicated, either statically by the programmer or dynamically by FG itself. FG also now alters thread priorities to use resources more efficiently; again, this action may be initiated by either the programmer or FG. To extend the range of computations that fit into its framework, FG now incorporates fork-join and DAG structures. Not only do fork-join and DAG structures allow for more programs to be designed for FG, but they also can enable significant performance improvements over linear pipeline structures.
