Abstract ECG recorders are precision medical devices, but their thin-walled shells are susceptible to warpage and shrinkage during injection molding production due to the injection molding process, which greatly shortens their service life. To address this problem, a multiobjective optimization method for injection molding process parameters based on a combination of a BP neural network model optimized by an ant colony algorithm (ACO-BP) and an improved non-dominated sorting genetic algorithm (NSGA-II) is proposed. The study takes the warpage deformation amount and volume shrinkage rate of the plastic part as the optimization objectives, and the melt temperature, mold temperature, injection pressure, holding pressure, holding time, and cooling time as the design variables. However, for BP neural networks, it is crucial to choose an appropriate number of hidden layer neurons, so the particle swarm algorithm combined with the grey wolf algorithm (GWO-PSO) is used to solve for the optimal number of hidden layer neurons. Firstly, the number of hidden layer neurons of the BP network model was solved based on the samples obtained from the Box–Behnken experimental design and the GWO-PSO algorithm, and the ACO-BP algorithm was used to build the prediction models for warpage and volume shrinkage, respectively, and then combined with NSGA-II for global optimisation. The pareto optimal solution set was subjected to CRITIC analysis and the optimal process parameters were finally obtained, with a minimum warpage of 0.3293 mm and minimum volume shrinkage of 4.993%, a reduction of 8.93 and 6.95% respectively compared to the pre-optimisation period. At the same time, injection molding tests were carried out on the optimum process parameters, and it was found that the molding quality of the plastic parts was better and met the actual production requirements through measurement. The research in this paper provides a theoretical basis for further improving the quality defects of the thin-walled injection molded parts.


Many modern and most future accelerators rely on precise configuration of lattice and trajectory. The Integrable Optics Test Accelerator (IOTA) at Fermilab that is coming to final stages of construction will be used to test advanced approaches of control over particles dynamics. Various experiments planned at IOTA require high flexibility of lattice configuration as well as high precision of lattice and closed orbit control. Dense element placement does not allow to have ideal configuration of diagnostics and correctors for all planned experiments. To overcome this limitations advanced method of lattice analysis is proposed that can also be beneficial for other machines. Developed algorithm is based on LOCO approach, extended with various sets of other experimental data, such as dispersion, BPM-to-BPM phase advances, beam shape information from synchrotron light monitors, responses of closed orbit bumps to variations of focusing elements and other. Extensive modeling of corrections for a big number of random seed errors is used to illustrate benefits from developed approach.


Abstract The Proton magnetic Resonance (PMR) spin-lattice and spin-spin relaxation times (T 1 and T 2) were measured in highly viscous (glycerine - water) and less viscous (dioxan-water) systems at different temperatures. The values of relaxation times increase with increasing the temperature. This result is interpreted as due to the combined effect of viscosity and temperature in these solutions. The relaxation times were also measured in these solutions containing paramagnetic ions(PMI). The results indicate that the possibility of an anti-parallel bonding of the paramagnetic ions is higher in highly viscous solutions as compared to low viscous systems and the association in the above mixtures appears to be weak.


An experiment was performed to evaluate the utility of an information storage model of distance cognition. Subjects walked matched routes segmented with either easily memorable or difficult-to-remember proper names. In accord with the information storage model, the route with more remembered attributes was consistently estimated as longer than an equivalent route with difficult-to-remember attributes.


The purpose of this study was to examine self-disclosure as both a personality trait and an interaction process. Forty men and women engaged in dyadic conversations with three same and three opposite-sex strangers and their spouses on each of three occasions. The conversations were coded for type of self-disclosure (descriptive vs. evaluative) and level of intimacy. The data were analyzed using Social Relations Analysis. The results of the study provided little support for individual differences in self-disclosure. In general, individuals were inconsistent in how much they self-disclosed to others and in how much self-disclosure they elicited from others. There were no sex differences in self-disclosure. There was qualified support for the process model of self-disclosure. The level of the relationship (spouse vs. stranger) affected self-disclosure, and self-disclosure was reciprocal for both spouses and strangers. However, there were no relationship differences in self-disclosure and self-disclosure was not related to liking.


The gene for one form of juvenile glaucoma has been mapped to chromosome 1q21-q31. This raises the possibility of primary open-angle glaucoma (POAG) also mapping to this region if the same defective gene causes both diseases. To ask this question linkage analysis was performed on a large POAG kindred. Blood samples or skin biopsies were obtained from 40 members of this family. Individuals were diagnosed as having POAG if they met two or more of the following criteria: (1) Visual field defects compatible with glaucoma on automated perimetry; (2) Optic nerve head and/or nerve fiber layer analysis compatible with glaucomatous damage; (3) high intraocular pressures (> 20 mm Hg). Patients were considered glaucoma suspects if they only met one criterion. These individuals were excluded from the analysis. Of the 40 members, seven were diagnosed with POAG; four were termed suspects. The earliest age of onset was 38 years old, while the average age of onset was 65 years old. We performed two-point and multipoint linkage analysis, using five markers which encompass the region 1q21-q31; specifically, D1S194, D1S210, D1S212, D1S191 and LAMB2. Two-point lod scores excluded tight linkage with all markers except D1S212 (maximum lod score of 1.07 at theta =more » 0.0). In the multipoint analysis, including D1S210-D1S212-LAMB2 and POAG, the entire 11 cM region spanned by these markers was excluded for linkage with POAG; that is, lod scores were < -2.0. In conclusion, POAG in this family does not map to chromosome 1q21-q31 and, thus, they carry a gene that is distinct from the juvenile glaucoma gene.« less

A 6 year-old male patient was admitted to the dermatology department with an eruption on the right arm, chest and left leg. No clinical symptoms such as pain, pruritus or previous inflammation were present. His mother reported that the lesion had developed four years ago as small-sized hyperpigmented macules which enlarged in a short period of time as band-like hyperpigmentation, and then remained unchanged. His past medical history was unremarkable and there were no similar cases in the family.On physical examination, band-like hyperpigmented patches on the right arm were observed. A similar lesion was located on the right side. When the right shoulder was on horizontal adduction, lesions of


INTRODUCTION
The Service of Health Professions of this facility (TO2 of Turin) aimed during the 2010 to devise/develop a new evaluation tool for the new employees , trying to fit them with the profiles set up the previous year.

METHODS
The conceptual model of reference for the construction of working drafts of the grids was inspired by the special insert edition of "L'infermiere" in 2007, a literature review was carried out and a number of internal meeting within 6 of the Service of health Professions were set up. A working group were set up - 93 people - as well as indicators were developed to monitor and implementation of the instruments. Once the drafts of the standard tools were made, working groups started to improve the tools provided under the supervision of a tutor. Finally half way through an evaluation was carried out using a questionnaire.

CONCLUSION
The new template leads a number of problems which were later sorted out also with the support of tutors.


A new Cd(II) coordination polymer, namely {Cd3(pbdc)3(e-murea)(DMF)}n·n(e-murea) (1, H2pbdc = terephthalic acid, e-murea = 1,3-dimethyl-2-imidazolidinone, DMF = N,N'-dimethylformamide), has been successfully synthesized via the urothermal reactions of Cd(II) ions and terephthalic acid ligand. Single-crystal X-ray structural analysis reveals that 1 features a two-dimensional layer framework with rod-shaped hexanuclear {Cd6(COO)12} clusters as building subunits. In addition, the luminescent property of 1 was also studied at room temperature.

In the paper the authors describe two tools for use in an intelligent fault-detection system. The first tool is a method for fault localisation, called constraint suspension, which helps us find and identify the parts suspension, which helps us find and identify the parts of the process which are responsible for any inconsistencies in the measurements. The second tool gives us a flexible framework in which we can build a software model of the process in terms of hierarchies of component parts or objects, it is called object orientation. We use these tools to describe algorithms for automatic fault detection in a physical process plant. The algorithms are tested on a simulation of a liquid level control system.

M any readers of CJM will recall the hysteria on the part of some sections of the media which accompanied the entry into force of the Human Rights Act in October 2000 it was predicted that the sky would fall in on law-abiding citizens as hundreds of dangerous criminals took advantage of their new charter. Now is an opportune moment to reflect on whether developments in criminal justice in the last four years have borne out such a fear, or whether, as this article will argue, it has been pretty much business as usual for the criminal justice system, with changes in some aspects of the criminal law, these changes identifiable mainly in the way in which legal issues are examined rather than in the result. That the latter position has prevailed will not surprise those aware of the fact that it was British lawyers, predominantly, who drafted the European Convention on Human Rights, and that the human right to a fair trial consequently embodies those values that have long been considered essential for a fair criminal law system. The main principle, set out boldly in art. 6(2), is the presumption of innocence, identified all those years ago in Woolmington' as the golden thread running through the web of English criminal law, and from which other standards (such as the privilege against self-incrimination) derive. Then article 6(3) creates certain practical rights to be informed of the charge, time to prepare a defence, legal aid, confrontation of witnesses, an interpreter that have generally been accepted in the UK as standard rights for some time. Criminal Justice Act 2003, something which probably will, in due course, be challenged. The ability of the criminal law to stifle political dissent has arguably lessened. The right to freedom of expression was instrumental in the quashing of a conviction for an offence of causing harassment, alarm or distress to US soldiers arising from the denigration of an American flag during a protest, on the ground that the conviction was incompatible with article 10." A similar argument failed in respect of a conviction for the religiously aggravated offence of displaying a poster which was threatening, abusive or insulting. A BNP member had displayed a poster of the Twin Towers in flames, with a crescent and star in a prohibited sign, and the words 'Islam Out of Britain'. The court found that marking out his conduct as criminal was a necessary restriction of his qualified right to freedom of expression in order to protect two of the interests set out in article 10(2), namely, the prevention of disorder and crime and the protection of the rights of others.


In this paper the development of a capacitive microphone with integrated preamplifier is described. The condenser microphone is made by micromachining of polyimide on silicon, and is compatible with CMOS technology. Therefore, the structure can be realised by post processing on substrates containing integrated circuits, independently of the IC process. Microphones with a required DC bias voltage of 4 V have been realised on a CMOS substrate containing PMOS buffer preamplifiers. From the measurements on these structures, it is illustrated how an immediate improvement of 4.8 dB of the microphone sensitivity and noise level can be obtained by using the integrated preamplifier. The measured sensitivity of the integrated condenser microphone was 2.5 mV/Pa and the equivalent noise level (ENL) was 29.5 dB(A) SPL.


The effect of different amino acids added to basal medium was observed with the aim of improving the enzyme production. Supplementation with L-valine, L-leucine, L-asparagine, L-lysine increased lipase production from Fusarium sp. SM-9 upto two-fold. This enhancement in yield of extracellular lipase has mainly been correlated with the chemical structure of amino acids.


Summary The study highlights the value of seismic attributes blending in characterizing a subaqueous fan reservoir, particularly when integrated with borehole image log analysis. With the introduction of techniques of borehole image facies analysis (Zhong et al., 2009), four borehole image facies associations were identified in Ep1 member, Pinghu oil field. The associations correlating to specific seismic reflection pattern can be broadly described by two reflection parameters, continuity and strength. In the practice, co-rendered maps of envelop and variance attributes were generated to highlight the differentiated reflection patterns as well as to resolve the favorable reservoirs which were interpreted as mid-fan channels sand-conglomerate and mid-channel sand braid bars from borehole images.


Domains for the exterior Dirichlet problem are unbounded. Now a new efficient probabilistic numerical method is proposed. It bases on the stochastic representations of solutions and make the problem over unbounded domains turned into a problem over boundary. Subdivision over boundary is needed to make the problem discretized. An auxiliary ball is constructed in the bounded domain outside the unbounded. The distributions of the time and place of hitting spheres for Brownian motion or Brownian motion with drift from outside spheres is emplored to gain the numerical solution.


Purpose: Carers of stroke survivors face a range of challenging demands. There is an increasing interest in using mindfulness-based interventions (MBIs) to provide support for carers. The main aims of this study were to assess the acceptability of an online MBI for carers of stroke survivors and the feasibility of recruiting into a wait-list controlled study design. Methods: Carers of stroke survivors were recruited through charitable and voluntary organisations. Participants were randomised to the intervention (an online, four-week MBI) or waitlist control group. Primary outcomes included participant feedback and/or interview, recruitment and retention rates and reports of intervention adherence. Outcome measures assessing burden, quality of life, stress, depression, anxiety, mindfulness and coping were also administered. Results: Twenty-seven people requested or made contact regarding the study and 15 consenting participants were screened and randomised. At six weeks, attrition was 40%. Overall, 12/15 participants accessed the MBI. Five participants completed it and feedback indicated the MBI was acceptable to them. Qualitative data from one withdrawn participant identified barriers to taking part. Intervention adherence could not be reliably assessed. Group medians, interquartile ranges and individual change analyses did not indicate a clear pattern of changes on outcome measures, although evidence of improvement and deterioration were identified on some. Conclusions: Results suggest limited feasibility of extending the current methodology to a larger trial. Carers' situations may pose limitations on their ability to engage in an online MBI, although for a subset of carers, this intervention appears acceptable. Recommendations for future trials are made.

The results of the study revealed that, while the culture types clan and market predicted the knowledge management dimensions of creation, capture, organization, storage and application, the culture types adhocracy and hierarchy predicted the knowledge management dimensions of storage and dissemination.


ABSRACT Tools of quality management serve for collecting and processing of data concerning different aspects of quality. They are instruments of supervising (monitoring) and diagnosing processes such as: designing, production, control, assembly and all different action appearing in the cycle of the product existence. Their meaning results from the fact, that without administering the honest and full information, it is difficult to say about taking effective action in the scope of systematic improvement of the product quality level. Article presents research results concerning quality improvement in chosen company from woodworking industry.


. The paper deals with the matter investigating the nature of the aesthetic impact of the belles-lettres style being generated within the scope of great transfer from high Middle Ages to the start of Renaissance. In course of the analysis, some traditional ideas and terms adopted in the historical stylistics are used. The mentioned ideas turned up into being during the period of its discrimination from other disciplines of linguistic historical cycle. Acquired linguistic independence charged the ideas with the function of marking the borders between the historical stylistics and other disciplines mentioned. One of the markers of the type is the voluminous historism, i.e., co-relationship between stylistic phenomena and the context of their existing. Flexible borders of the latter regulated by targets and tasks of the proper research can be extended up to the certain type of culture. Importance of a special character gained by the medieval culture during the period of the «international» Gothic dominating when considered as a type of a context necessary for analysing the belles-lettres style generating corresponds to the importance of combining philological and non-philological kinds of practice and induced by the purpose to enrich the analysis as well as to increase the research output verification. It is suggested that the analysis of the elements of another semiotic nature presented by types and illustrations highly important for discursive strategies to influence the recipient should be thought of as an instance of a combination of the kind. One of the mighty instruments of the mentioned sort of the esthetic impact is the medieval illuminated book of the epoch of the "international" Gothic (XIV — XV centuries) dominating within the borders of European cultural space. «Soft» power, immanent to it, id est, some ability to modify emotional state of consciousness and behaviour of a recipient is characterised by semiotic attractionness and cognitive power, and embodies one of the type of strategies of the kind.

Space motion sickness is a condition which frequently occurs shortly after attainment of sustained exposure to microgravity and affects 73% of crew members on the first 2 or 3 days of their initial flight. The characteristic symptoms and signs include vomiting, retching, pallor, flash, cold sweating, yawning, belching, flatulence, and decreased gastric tonus. The severity of space motion sickness is variable, but over half of the cases are categorized as moderate to severe. In-flight and post landing immunity to the coriolis sickness susceptibility test (CSSI) observed during the Skylab M131 experiment suggests that the otolith organs play an important role in space motion sickness. This view is supported by a study that ocular counter rolling asymmetries are correlated with space motion sickness incidence and severity. It has also been reported that sensory-motor adaptation to microgravity includes a process whereby central interpretation of the otolith signal is biased from tilt toward translation. Perceptual studies provide some support for this "otolith tilt-translation reinterpretation" hypothesis and have also suggested orientation to the long axis of the body or to the surrounding spacecraft after adaptation to microgravity. In the Neurolab project, using space shuttle "Columbia", several experiments were performed to determine how microgravity affects the orientation vectors of the vestibulo-ocular reflex (VOR) and optokinetic nystagmus (OKN) and how they are altered by introducing a linear force due to centrifugal acceleration in an eccentric rotator. We discussed here, some current aspects regarding space motion sickness.


This paper deals with the complexity of the problem of computing a pure Nash equilibrium for discrete preference games and network coordination games beyond O (log n ) -treewidth and tree metric spaces. First, we estimate the number of iterations of the best response dynamics for a discrete preference game on a discrete metric space with at least three strategies. Second, we present a sufficient condition that we have a polynomial-time algorithm to find a pure Nash equilibrium for a discrete preference game on a grid graph. Finally, we discuss the complexity of finding a pure Nash equilibrium for a two-strategic network coordination game whose cost functions satisfy submodularity. In this case, if every cost function is symmetric, the games are polynomial-time reducible to a discrete preference game on a path metric space. construct a pure Nash equilibrium for a cartesian game from pure Nash equilibria for the discrete preference games that form that cartesian game. Our results are the first polynomial-time computability of discrete preference games on neither O (log n ) -treewidth nor tree metric spaces.


In this paper, we present a rapid and simple method to fabricate superaerophilic polytetrafluoroethylene cones via a two-step femtosecond laser direct writing technique, which enormously improved processing efficiency compared to the existing method. The laser-treated cones contained hierarchical microstructures and exhibited self-driven and directional transport of gas bubbles along the cones and away from the tip, even when the cones were horizontal. Furthermore, the laser-treated cones exhibited excellent chemical and long-term stability. This work may provide an effective and simple approach to obtain efficient manipulation of gas bubbles in practical applications.In this paper, we present a rapid and simple method to fabricate superaerophilic polytetrafluoroethylene cones via a two-step femtosecond laser direct writing technique, which enormously improved processing efficiency compared to the existing method.

Abstract Visibility of the road influence the safe driving because it recognizes the obstacle on the road. In this paper, we propose a mobile data acquisition and processing system for evaluating road visibility at night. And it was converted efficiently with mobile images and archived for spatial analysis of road-visibilities at night. This was applied to the following techniques to the system. Low-power computing units, open an image processing library, GPU-based acceleration techniques and document database techniques, etc. And converting the RGB image to the YUV color system, which was integrated the brightness component and the spatial information. High performance Android devices were used to collect brightness data on roads and it was confirmed whether this prototype was to determine the spatial distribution of such acquisition and management systems for spatial-assessments of road visibility at night.Keywords: Road, Visibility, GIS, Mobile, Android 1. 서 론 1.1 연구배경 및 목적국가별 교통사고 발생 현황을 분석한 자료에 의하면 우리나라는 경제협력개발기구(OECD)회원국 중 교통사고 사망률이 매우 높은 것으로 조사되었다. 갑작스러운 날씨변화(국지성 호우, 안개, 눈)로 인하여 운전자들의 시인성 확보가 어려워 교통사고가 많이 발생하는 것으로 알려져 있다. 맑은 날에 비해 안개 낀 날의 교통사고 치사율이 3.15배가 높으며, 흐리거나 우천 시에는


Financial service firms, and banks in particular, are faced with a shift from traditional, interpersonal forms of service to online services. Digital technologies are more and more becoming today's standard and challenge traditional business models in the banking sector. Building on the concept of Entrepreneurial Orientation (EO), this study of banks in Germany, Switzerland and Liechtenstein aims at developing insights that explain how banks can use the tactics and strategies associated with EO to achieve superior performance in the digitalization age. Results from a survey in 102 banks show that: 1) banks that display high levels of EO report a higher level of performance, and 2) the relationship between strategic vision on digitalization and performance is moderated by EO. These results indicate that the sheer level of digitalization of a bank does not affect profitability. Instead, banks should develop a clear vision on digitalization that is characterized by innovation, being ahead of the competition, and a willingness to take risks.


Background The effect of health targeted aid in developing countries is debatable. This paper examines the short run effect of health aid on health status in low income countries of the world. Method The study estimates the short run effect of health aid on health status in low income countries. Infant mortality rate was used as a proxy for health status and a panel data was constructed from 34 countries for the period between 2000 and 2017. For the estimation, first difference GMM and System GMM were employed. Results The estimation results confirm the argument that health aid has a beneficial and statistically significant short run effect on the health status of low income countries: doubling health aid saves the lives of 20 infants per 10,000 live births. Conclusion From the findings of this paper it can be concluded that health aid could be one of the best tools with which the broader health status gap currently observed between high income and low income groups, could be eliminated and hence the target of Universal Health Coverage is met. However, recipient countries need to find ways of promoting domestic factors that have favorable impact on health sector as they cannot persistently relay up on external resources.


This paper concerns the asymptotic behaviours of pulse-like solutions for a 3 × 3 semilinear hyperbolic system in the limit of short wavelength ε. When two pulses interact with each other, we construct a pulse-like approximate solution up to Ο(ε), at which order a new pulse appears. The existence of a solution to the 3 × 3 semilinear problem with the initial data being the interaction of two pulses in a domain independent of the wavelength is proved in the space of co-normal distributions. Meanwhile, we obtain that the error between this exact solution and the approximate solution is of Ο(ε2) as ε → 0, which rigorously shows that there are three pulses propagated after the interaction of two pulses for the 3 × 3 semilinear system.


What William Emerson encountered at Gottingen University were new ideals of biblical research that removed the Scriptures from narrow theological grounds and subjected them to a criticism that evaluated the historical reliability of the biblical texts. The challenge to the evidentialist framework came from the branch of biblical studies designated as "higher criticism" which forced discussions on the authority of Scripture, the meaning of history, and the nature of faith. The influence of these commentators in the Lord's Supper sermon was clear to Edward Waldo Emerson because of his father's "unusual and remarkable" rational exegesis. This rational exegesis was by no means unusual for Ralph Waldo but rather accorded with the exegetical principles and techniques of his vestry lectures. Emerson's rejection of the Lord's Supper as an empty ritual was aligned with a christology that played down the revelatory significance of the human figure of Jesus.Keywords: authority of Scripture; Edward Waldo Emerson; Gottingen Students; human figure of Jesus; Lord's Supper; Ralph Waldo Emerson; rational exegesis

Abstract : Prior to the advent of the aging aircraft problem, the criterion for ensuring USN airframe safety was a damage index labeled FLE (Fatigue Life Expended). In retrospect, over several decades, the application of the FLE criterion has provided an exemplary, cost effective, structural-safety record. However, with today's realities, the structural engineering community is being directed to maintain airframes longer than originally envisioned and fly beyond the FLE criterion. Consequently, a reliability assessment will provide management with the needed technical support in order to make informed decisions regarding aging airframes and maintenance demands.


Mungbean Yellow Mosaic Virus (MYMV) is a serious pathogen on mungbean in southern Karnataka where the crop is grown during early kharif by making use of pre monsoon showers. Survey of major mungbean growing areas of Southern Karnataka indicated the occurrence of disease ranging from 31.49 to 100 per cent. The highest average incidence (79.54%) was recorded in Tumkur district followed by Chickmagalur (59.73%), Hassan (56.57%), Shimoga (56.71%), Mysore (51.88%), Davanagere (51.09%), Chitradurga (48.11%) and Mandya district (45.58%). The RAPD analysis of whitefly samples collected in the surveyed areas has indicated the occurrence of B biotype Bemisia tabaci. The occurrence of B biotype of B. tabaci and large scale cultivation of susceptible varieties are implicated as the reasons for increased incidence of MYMV in these areas.


Magnetic‐fluid‐loadedliposomes (MFLs) of optimized magnetic responsiveness are newly worked out from the entrapment of superparamagnetic maghemite nanocrystals in submicronic PEG‐ylated rhodamine‐labelled phospholipid vesicles. This nanoplatform provides an efficient tool for the selective magnetic targeting of malignant tumors localized in brain and non‐invasive traceability by MRI through intravascular administration. As assessed by in vivo 7‐T MRI and ex vivo electron spin resonance, 4‐h exposure to 190‐T m–1 magnetic field gradient efficiently concentrates MFLs into human U87 glioblastoma implanted in the striatum of mice. The magnetoliposomes are then longer retained therein as checked by MRI monitoring over a 24‐h period. Histological analysis by confocal fluorescence microscopy confirms the significantly boosted accumulation of MFLs in the malignant tissue up to the intracellular level. Electron transmission microscopy reveals effective internalization by endothelial and glioblastoma cells of the magnetically conveyed MFLs as preserved vesicle structures. The magnetic field gradient emphasizes MFL distribution solely in the tumors according to the enhanced permeability and retention (EPR) effect while comparatively very low amounts are recovered in the other cerebral areas. Such a selective targeting precisely traceable by MRI is promising for therapeutic applications since the healthy brain tissue can be expected to be spared during treatments by deleterious anticancer drugs carried by magnetically guided MFLs.


It is common to conduct causal inference in matched observational studies by proceeding as though treatment assignments within matched sets are assigned uniformly at random and using this distribution as the basis for inference. This approach ignores observed discrepancies in matched sets that may be consequential for the distribution of treatment, which are succinctly captured by within-set differences in the propensity score. We address this problem via covariate-adaptive randomization inference, which modifies the permutation probabilities to vary with estimated propensity score discrepancies and avoids requirements to exclude matched pairs or model an outcome variable. We show that the test achieves type I error control arbitrarily close to the nominal level when large samples are available for propensity score estimation. We characterize the large-sample behavior of the new randomization test for a difference-in-means estimator of a constant additive effect. We also show that existing methods of sensitivity analysis generalize effectively to covariate-adaptive randomization inference. Finally, we evaluate the empirical value of covariate-adaptive randomization procedures via comparisons to traditional uniform inference in matched designs with and without propensity score calipers and regression adjustment using simulations and analyses of genetic damage among welders and right-heart catheterization in surgical patients.


It is widely thought that Augustine thinks perception is, in some distinctive sense, an active process and that he takes conscious awareness to be constitutive of perception. I argue that conscious awareness is not straightforwardly constitutive of perception and that Augustine is best understood as an indirect realist. I then clarify Augustine's views concerning the nature and role of diachronically unified conscious awareness and mental representation in perception, the nature of the soul's intentio, and the precise sense(s) in which perception is an active process.


Abstract - We quantified microhabitat use of Etheostoma inscriptum (Turquoise Darter) in 2 streams in the Oconee River watershed in the Georgia Piedmont using snorkeling observations during September 2020. This species has a restricted distribution, and little is known about its habitat associations. Principal component analysis indicated that Turquoise Darters were over-represented in patches characterized by higher column and bottom water velocities and higher percentages of erosional substrata (gravel or small cobble) at both sites. Turquoise Darters were under-represented in patches characterized by higher amounts of depositional substrata (sand and silt) in both sites. These results indicate that sedimentation and hydrological alterations could limit suitable habitat for Turquoise Darters.


Present Tourism Strategy focuses on increasing tourism related employment in Sri Lanka. It is difficult to attract entry level employees to tourism industry given many reasons. This study aims identifying barriers for potential employment for people in rural areas and it will facilitate human resource builders in tourism industry. As a rural area with pool of job seekers, Kotmale was selected for this study. The sample size has been determined by using stratified sampling method and convenience sampling method was used to select respondents. Primary data collected through a pre-tested structured questionnaire and secondary data were used for the study. Mixed methodology was employed to analyze data. The results revealed social considerations, recruitment process, skills development, progression pathways, cultural barriers and lack of infrastructure facilities are significant barriers for tourism employment in rural areas. It is recommended to address the above to make tourism employment attractive for rural job seekers.

Introduction
Cardiac non-specific inflammatory pseudotumors (NSIPT) are exceptionally associated to Behçet's disease (BD) and represent a real diagnostic and therapeutic challenge. The meaning and the mechanisms of this association are not yet well understood. The purpose of this paper is to study the epidemiologic, therapeutic, and evolutionary characteristics of cardiac NSIPT during BD

Methods
Systemic review of all reported cases of cardiac NSIPT associated with BD.

Results
We found only 6 cases of NSIPT associated with BD. Of these six patients, 4 were men (66.66%) and 2 were women (33.33%): Sex ratio =2. The average age was 26.66 years (9-35 years). The pseudotumor was unique in all cases. The chronology of occurrence of these NSIPT compared to the underlying angiitis was variable: inaugural of the disease in 4 cases, and complicating a previously known BD in 2 cases. The surgery was performed in all cases. It was carried out for diagnostic purpose in 4 cases, and therapeutic in the other 2. Additional medical treatment based on systemic corticosteroids with or without immunosuppressants was indicated in 4 patients. The evolution was favorable in 5 cases and a single case was quickly fatal. Recurrence of NSIPT was reported in one patient (20%).

Conclusion
The results of this review suggest a very likely association between BD and cardiac NSIPT; especially because of the scarcity of these two conditions in the general population, and the epidemiological characteristics clearly different from those of cardiac NSIPTs in the general population. The pathogenic mechanisms common to these two conditions (immune, inflammatory, reactive, and vascular) reinforce this causal link. The main differential diagnoses of these pseudotumors during BD remain cancer and intracardiac thrombosis.

A definitive diagnosis of a brain tumour is essential for enhancing treatment success and patient survival. However, it is difficult to manually evaluate multiple magnetic resonance imaging (MRI) images generated in a clinic. Therefore, more precise computer-based tumour detection methods are required. In recent years, many efforts have investigated on classical machine learning methods to automate this process. Deep learning techniques have recently sparked interest as a means of diagnosing brain tumours more accurately and robustly. The goal of this study therefore is to employ brain MRI images to distinguish between healthy and unhealthy patients (including tumour tissues). As a result, an enhanced convolutional neural network is developed in this paper for accurate brain image classification. The enhanced convolutional neural network structure is composed of components for feature extraction and optimal classification. Nonlinear Lévy Chaotic Moth Flame Optimizer (NLCMFO) optimizes hyperparameters for training convolutional neural network layers. Using the BRATS 2015 data set and brain image datasets from Harvard Medical School, the proposed model is assessed and compared with various optimization techniques. The optimized CNN model outperforms other models from the literature by providing 97.4% accuracy, 96.0% sensitivity, 98.6% specificity, 98.4% precision, and 96.6% F1-score, (the mean of weighted harmonic value of CNN precision and recall).


We point out the existence of new effects of global spacetime expansion on local binary systems. In addition to a possible change of orbital size, there is a contribution to the precession of elliptic orbits, to be added to the well known general relativistic effect in static spacetimes, and the eccentricity can change. Our model calculations are done using geodesics in a McVittie metric, representing a localized system in an asymptotically Robertson-Walker spacetime; we give a few numerical estimates for that case, and briefly comment on ways in which the model should be improved.


A contribution to development of compact and cost-effective bandpass filters in a multilayer substrate is presented. Miniaturization of the filters is achieved by a three-dimensional (3-D) design approach and an anisotropic artificial dielectric of a high permittivity. The 3-D approach is provided by the use of both a planar transmission line and a vertical interconnection formed by signal and ground vias. The artificial dielectric, occupying the vertical interconnection, is formed by a conductive plate connected to the signal via. Improvement of the electrical performance and controlling bandwidth in the filter is made by specific anisotropy of the artificial dielectric which is provided by corrugations of the conductive plates. Bandpass filters based on two types of corrugations have been presented. In the first type, the corrugations are oriented in parallel to the microstrip line connecting two signal vias, while in the second one they are perpendicular to the microstrip line. Simulation and measurement data, which are in a good agreement, show characteristic features of proposed components.


Four tissue compartments, differing in proton and inorganic phosphate concentration, were resolved by 31P-NMR spectroscopy in samples from dog hearts after cardioplegic treatment with HTK solution. Inversion of the physiological cytoplasmic-mitochondrial pH gradient was observed. The considerable ensuing acidosis of the matrix is discussed with regard to a possible delocalization of ferrous ions.

Introduction: Patients with diabetes mellitus (DM) and angina have high morbidity and mortality after negative stress cardiac imaging, and myocardial perfusion reserve (MPR) measures provide additional prognostic information. We aimed to determine the association of abnormal MPR with the extent of coronary artery disease (CAD) in symptomatic diabetics. Method: Symptomatic diabetics age 18-85 without known CAD referred for stress imaging were included. Quantitative stress CMR and coronary CT angiography (CTA) were performed. Plaque distribution was characterized by "segment score" (max score of 16). Plaque severity was graded as 0=none; 1≤30%; 2=30-50%; 3=50-75%; 4≥75%. Plaque scores were summed across all segments into a "total plaque score" (max= 64). Quantitative CMR perfusion analysis was performed using Fermi deconvolution. Patients were stratified by MPR <2 and ≥2. Data were compared using Kruskal-Wallis and Fisher's Exact testing. Result: Complete data were available in 39 patients. Median age was 5...


The formulation of oral disintegrating films has led to the development of wafers which has modified itself in the recent past years. Wafers are more advantageous over other conventional dosage forms as well as from other oral disintegrating solid dosage forms. The major difficulty in formulating wafers is the choice of drugs to be incorporated. Wafers with a low dose of active pharmaceutical ingredient (API) and with a good mouth feel are prepared for making it more patients compliant. The manufacturing procedures are quite similar to oral disintegrating film, but the composition of polymers may vary. The wafers require expensive packaging and care should be taken while handling, storage & transport. In spite of these hardships, wafers have become popular between geriatric and paediatric population because of its ease of administration and bioavailability.


Background: The cause of preeclampsia in pregnancy is not yet known for certain. But one of the risk factors for preeclampsia is age. The safest age for a woman to get pregnant and to give birth is between the ages of 20-35 years, since women of that age are in a healthy reproductive period. Maternal deaths in pregnant and delivery mothers at age 35 years will increase significantly.
Objective: To determine the relationship between the status of primigravida to the occurrence of preeclampsia based on age.
Method: The type of research that will be used is analytical research using case control approach done in three (3) Maternity Hospital of Makassar city which conducted in November until December 2017
Result: The result of statistical test using Chi-square test, primigravida status to preeclampsia is 0,000 (p = 35 years risk 7 times 7293 risk to be affected by preeclampsia compared with pregnant women aged between 20-35 year. Likewise, between the age of the mother and the occurrence of preklampsia showed a significant relationship with the value of OR (Odds Ratio) of 4.886, which means pregnant women aged 35 years at have 4,886 times the risk of getting preeclampsia compared with pregnant women Aged between 20-35.
Conclusion: There is a significant correlation between primigravida by age and is a risk factor for the occurrence of preeclampsia.
Keywords: Preeclampsia, primigravida, maternal age, risk factor of preeclampsia.


The COVID-19 pandemic had brought about a standstill to many activities across the world. Health experts, doctors and academic investigators across the globe have been attempting to come to terms with the trying demands posed on the human population due to the pandemic. This paper attempts to develop a precise model for examination of and forecasting effective measures to be implemented during different situations to limit the impact of COVID-19. It also addresses various trials and tests faced while using machine learning algorithms. For the experimental analysis different parameters such as countries (China, America, India, South Africa and Italy), month, types of measures to be undertaken (awareness campaigns, economic measures, domestic travel restrictions, health screening at airports and psychological assistance involving medical social work) and date of implementation details are considered. COVID-19 epidemic determent procedures by recognizing, evaluating danger situation and probable paths of epidemic using a machine-learning technique have been explored. A proposed methodology to forecast extension of lockdown in order to exterminate COVID-19 is presented wherein SVM regression technique is used for prediction of actual extension of lockdown during the pandemic situation.


The purpose of this study was to determine the effects of constructivist methods on student learning in an undergraduate art appreciation class. Three constructivist learning activities were designed and implemented in an undergraduate art appreciation course for non-art majors at Mississippi College. Through these constructivist learning activities, students were involved in their learning throughout the semester in realistic art roles in which they worked as curators, Web page designers, and artists. Six subjects were selected to participate in this case study. Subject data was collected through three methods: interviews with subjects at three points during the semester, student documents produced during the three activities, and a field journal of observations made during the activities. The multiple data sources were triangulated to reveal nine patterns of learning. The data evidence that constructivism results in a deeper understanding of art and art processes than in a typical art appreciation course in which learners are merely passive recipients of knowledge. This was not only indicated by the nine patterns of learning which emerged from the data, but also in the students' awareness and regulating of their cognitive processes. Although the research provided an in-depth understanding of this case and should not represent or be generalized to the entire population of art appreciation students, the results of this study suggest that art appreciation instructors have an opportunity to facilitate high levels of student thinking and encourage metacognitive skills through constructivist methods such as the ones used in this study.


the simplicity of its preparation. The dose–response curves of the colorimetric assay MTT carried out in HCT 116 cell cultures in a range from 30 to 250 μg/ mL reveal that magnetic nanoparticles coated with DMSA significantly improve their biocompatibility for applications like magnetic hyperthermia, magnetic resonance imaging, or biosensing.

2 METHODS: 34 female soccer players participated in a 6-week training study (age 13.3±1.5yrs; height 158.7±6.9cm; mass 50.0±9.6kg). Maturation groups were determined based on percent of adult stature (PAS) with 88-94% representing pubertal (n=9, PAS 91.6±2.0%) and 95-100% representing post-pubertal (n=25, PAS 97.7±1.7%). Three 30 minute sessions, separated into plyometric, resistance, and core strength training, were completed each visit for a total training time of 90 minutes three times per week. Participants wore HR monitors during each plyometric session. The initial exercises were adapted from ACL IPP, and intensity of each exercise was progressed weekly following the second week of training (5 total phases). HR max was calculated for each participant during each session and averaged weekly. A linear mixed model (p<0.05) was used to determine the effects of HR max over the six-week intervention in pubertal and post-pubertal female soccer players. Average HR during the first week of training was used as a covariate. RESULTS: A significant interaction of maturational group and training week was found (p<0.04) with HR max . A main effect of training week was found in both pubertal (p<0.001) and post-pubertal (p<0.01) groups. HR max was significantly increased in both groups (week 1 to week 3, p<0.05) following the first two technique focused weeks of plyometric program with the pubertal group (184.3±4.7 BPM) having greater HR max compared to the post-pubertal group (172.7±2.2 BPM) during week 3. CONCLUSIONS: Physiologic responses to load was dependent on maturation stage and should be further examined in relation to reduced risk of injury following IPP.

The article proposes an approximate method for separating the state variables of a linear singularly perturbed discrete control system with a small step. The resulting system with separated state variables is equivalent to the original one, since it possesses all the controllability and stabilizability properties of the original system. It consists of two low-order subsystems, the solutions of which can be found independently, and they are connected only by the control function.
In the article, to illustrate the proposed method, an example is considered that confirms the theoretical conclusions.

Fluidized bed combustion (FBC), today's fastest growing boiler technology, has the flexibility to burn a wide range of fuels, including many waste fuels, while satisfying all present and anticipated environmental regulations. The first generation of FBC--atmospheric fluidized bed combustion (AFBC)--concentrated on ''bubbling'' fluidized bed designs. These systems have inherent limitations and experienced several problems. In response to these problems, circulating fluidized bed (CFB) technology was developed.


The paper discusses possible variants of practising a wold-non proven alternative method of sublevel ore caving with areal-frontal drawing. The authors present the results obtained in physical simulation of ore drawing, and illustrate the advantages of the new method of drawing-off level preparation over the frontal ore drawing scheme. Relationships between extraction indexes, ore breaking parameters and drawing regime have been determined, and a feasibility study has been performed for the innovative alternative method in terms of an ironore enterprise.


The study circumscribes to the Portuguese territory region placed in the north of Douro river, with very charismatic geomorphologic characteristics as well as villages and local architecture structures. Therefore, considering three regions in the north of Douro river, this study is especially addressed to the Minho and Trás-os-Montes regions (see image 1), although it might arise, punctually, one or another specific reference to examples of Douro Littoral region.

I Turkey, reimbursement of nonvitamin K oral anticoagulants (NOAC) mandates a time in therapeutic range (TTR) of <60% during warfarin use for the prevention of stroke in people with atrial fibrillation (AF). The Health Implementation Directive (SUT: "Sağlık Uygulama Tebliği" in Turkish) Drug Use Principles are stated in 4.2.15 exactly as follows: "If the target International Normalized Ratio (INR) value cannot be kept between 2-3 with warfarin in at least three of the last 5 measurements made at least one week apart, warfarin may be discontinued and rivaroxaban or dabigatran or apixaban or edoxaban treatment can be started." There is no doubt that TTR is one of the main parameters determining the efficacy and safety of oral anticoagulation with warfarin. For the treatment to be considered successful, it is suggested that TTR should be above 60% or at least not below 55%. This threshold had been achieved in the major NOAC trials in the AF population; the TTR value was 64% in RELY,[1] 62% in ARISTOTLE,[2] 55% in ROCKET-AF,[3] and 68% in ENGAGE-AF TIMI-48.[4] However, outside the rigorously ordered environment of randomized controlled trials, the TTR value is often below 50% in real-life. We have performed a systematic literature review and pooled analysis to investigate the TTR status in Turkey with the goal of providing guidance to change the current problematic prescribing rules. The latest manual of Preferred Reporting Items for Systematic Reviews and Meta-analyses was followed for reporting.[5] A total of 1,658 articles were detected in PubMed between 1980 and 30 October 2020 after a search with the keywords "Turkey" and "atrial fibrillation." After a review of the titles, 40 articles related to the subject were identified, and their abstracts were evaluated. Thirteen of them were not related to the subject studied. The full texts of the remaining 27 articles were reviewed in detail, and 5 articles were considered suitable for the analysis.[6-11] With the Snowball technique, 720 additional articles were screened from the sources of these articles and the articles they referred to in PubMed. This led to the identification of 6 additional articles suitable for the analysis herein.[12-17] No additional studies could be extracted from further search in Google Scholar (1,230 articles were detected with "therapeutic range", used in addition to the same keywords, up to 4 February, 2021) and WoS (Web of Science) databases (with the same keywords for the topic, total 95 articles, up to 4 February, 2021).


Abstract : Diver cores were collected from various locations within the SAX04 site from 21 September to 3 November 2004 and compressional wave speed and attenuation were measured every centimeter at 400 kHz. Although measured values of sound speed and attenuation fall within established ranges for archived data from similar medium quartz sands, fluctuations in measured values were observed in the data that can be explained by the pattern of storm events during the experiment. Three significant storm events occurred during the period in which cores were collected: a category-4 hurricane, a tropical storm, and an early-winter cold front. Following these events values of sound speed initially increased, but then later decreased; values of sound attenuation did not show this pattern, but were generally lower (mean = 92.1 dB/m) than values measured. five years ago at the SAX99 site nearby (mean 177.5 dB/m). Values of sediment sound speed measured at the SAXO4 (mean velocity ratio = 1.162) were generally greater than those measured at the SAX99 site (mean velocity ratio = 1.155). Values of coefficient of variation for sediment sound speed were lower for SAXO4 measurements (0.55%) than SAX99 measurements (0.70%). Lower values of sound attenuation measured at the SAXO4 site was probably due to a lack or absence of shell fragments that may have been segregated by the sediment resuspension and settling during and after storms. The roles of sediment transport, grain size, grain sorting, porosity, and density in controlling sediment compressional wave speed and attenuation at the SAXO4 site are discussed.


ABSTRACT In this study, a novel nitrated bacterial cellulose/2,4,6,8,10,12-Hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane/ammonium perchlorate nanoenergetic composite was successfully prepared by the sol–gel method and the freeze-drying technology. The structure and composition were characterised by means of scanning electron microscope, X-ray diffractometer and Fourier-transform infrared. The results demonstrated that the structure of the gel nanoparticles was granted with unique network cross-linked porous, wherein the hexaazaisowurtzitane and ammonium perchlorate nanoparticles were embedded and dispersed uniformly in the gel matrix. The thermal decomposition properties of composites were analysed by differential scanning calorimeter-thermogravimetric analysis, and the results revealed that the composites exhibited only two exothermal peaks which correspond to the nitrated bacterial cellulose/hexaazaisowurtzitane and ammonium perchlorate. In addition, the impact and friction sensitivities of composites were also performed and showed outstanding safety performance. Hence, this preparation strategy of nitrated bacterial cellulose-based nanocomposite energetic materials may provide promising application in high-performance and low-sensitivity propellants.


ABSTRACT This study examined whether pragmatic ordering factors account for the apparent preference for ANIMATE-INANIMATE (AI) order in passive and active sentences. If so, learning noun order relations in NNV sequences with an INANIMATE PATIENT + ANIMATE AGENT (It's the drum the boy plays) should be more difficult than with an ANIMATE PATIENT + ANIMATE AGENT (It's the girl the boy chases). Seventy children aged 3;0 to 5;3 were trained with either AAV or IAV exemplars, and then tested for their noun order in NNV utterances when describing animate agent + animate patient and animate agent + inanimate patient pictures. As judged by post-training performance, AAV and AIV training had comparable effects at age three, but IAV resulted in better learning at ages four and five. It was argued that the latter benefited from the correlation between animacy and subject in English sentences.

SUMMARY Four experiments investigated some of the factors affecting the digestion of whole maize grain in non-lactating cows and yearling steers. With steers, but not cows, maize in diets containing small amounts of hay (14%) and large amounts of whole grain were better digested than those with 37 or 48% hay. The higher digestibility of maize in steers was associated with a greater time spent ruminating per kg feed and a longer retention time of maize in the gut than in cows. Replacing long roughage with ground and pelleted roughage in diets for steers improved the digestion of whole maize but not as well as reducing the hay to 14% of the diet. Finely grinding the maize produced a large increase in digestibility of the feed in cows and steers and both digested it to the same extent. It was concluded that the motility of the reticulo-rumen during eating and ruminating largely determines the extent of the digestion of whole maize grain.


Abstract The role of tannins in Helicoverpa zea (Boddie) larval mortality in H. zea nuclear polyhedrosis virus (HzNPV)-exposed third instars was examined in bioassays on semisynthetic diet. Mortality was observed in H. zea larvae not exposed to HzNPV when reared on diet that contained tannic acid at 0.025, 0.05, and 0.1% (w/v) but not on diets that contained Quebracho (condensed tannin) or catechin. The percentage of mortality (45.8%) of third instars fed HzNPV diet was significantly less when Quebracho tannin but not catechin was added to the diet (P ≤ 0.05). At the 0.025% rate of tannic acid, the percentage of mortality in larvae fed HzNPV was significantly less than that expected from the tannic acid-HzNPV mixture. The HzNPV-exposed larvae fed on Quebracho tannin diets also had significantly lower (corrected) mortalities than did HzNPV-exposed larvae fed on tannic acid and catechin diets. Larval mortality was delayed in all tannic acid treatments. When larvae were exposed to an aqueous suspension of HzNPV that was 0.025, 0.05, and 0.1% (w/v) tannic acid or Quebacho tannin prior to being placed on diets without a source of tannin, mortality was significantly reduced on the tannic acid diets but not on Quebracho tannin diets. Larval mortality was not altered significantly when larvae were exposed to HzNPV in tannin-free aqueous suspensions prior to being placed on the tannic acid or Quebracho tannin.


We are educated by the American creed of accomplishment to believe that every problem, however defined, is susceptible to solution through the application of reasoned effort. Difficult problems simply are those which demand greater measures of reasoned effort to achieve solution. As a corollary, it is supposed that difficulty and complexity are the same, so that a difficult problem must be a complex problem.


: Now a day's friend recommendation has a greater impact on social networking. Friend recommendation based on social graph may not be most relevant to reflect user's expectation on friend selection. Propose approach Based on novel semantic friend recommendation includes life-styles similarities based on text-mining. Using Text mining daily activities of user's are modelled as life document. In this approach user's daily life activities, lifestyles, habits, hobbies etc. can be extracted and generating similarity measure by calculating similarity impact. When receiving friend request system gives a list of user's with highest recommendation score. After receiving recommendation, user can provide feedback which improves further recommendation accuracy..


The macula, which is the noblest part of the retina, is a very small structure, containing the photoreceptors (rods and cones) responsible for visual acuity. Over the years, observations have confirmed that alterations that modify the optimal state of the eye also give rise to similar diseases in the brain: ischemias, structural circulatory alterations and neurodegeneration. As the body ages, oxidative alterations take place and they change the antioxidant systems that serves as a neurological and ocular defence. In industrialised nations, age-related macular degeneration is the leading cause of blindness in patients over 55 years of age. Initially, this creates drusen (or colloid cysts) in the macular area.


The reaction of (E)- or (Z)-cinnamyl alcohol and ethyl vinyl ether with a catalyst consisting of Pd(OAc) 2 , Cu(OAc) 2 , and catechol (1:1:2) under O 2 gives a good yield of(Z)- or (E)-4-benzylidene-2-ethoxytetrahydrofuran, respectively. Similarly, 2-butoxy-4-exomethylenetetrahydrofuran was obtained from allyl alcohol and butyl vinyl ether. In the case of allyl alcohol, however, the catalysis does not proceed well with forming palladium black, if a relatively large amount of Pd(OAc) 2 , such as 0.25 mmol to 0.05 mmol, is used even in a lower palladium/substrate ratio, e.g. 1 mol% concentration of the catalyst.


T ake a look at the products you use every day. Telephones, personal computers, the soft drink you had with lunch-each was probably manufactured in a highly automated facility Fixed automation and, more recently, flexible automation and robotics, have greatly reduced the cost of many manufactured products by reducing labor requirements, increasing the speed of production, and, in many cases, improving quality and safety. Now look at the building in which you live or work. While many of the components that make up this building may have been manufactured in automated facilities, the building itselfwas most likely assembled (constructed) using a great deal of manual labor. Could the construction industry reap some of the benefits of automation that have been seen in manufacturing? Many people, both in the U.S. and abroad, think the answer is yes.


Steel suspension members subjected to tension and bending offer an economical and efficient alternative for many structural problems. This paper is concerned with the elastic and elastic-plastic behaviour of suspension members with bending stiffness subjected to vertical point and uniformly distributed loads. An experimental study is described which focuses on the response of three suspension members with various T-shaped steel hot rolled sections and geometric configurations. The tests enable direct assessment of the influence of a key parameter such as the sag-to-span ratio on the response of suspension members. Detailed nonlinear finite-element models are generated to provide a tool for theoretical analyses and to facilitate further understanding of the behaviour. Results demonstrate that experimentally obtained responses can generally be closely predicted numerically because there are relatively good agreements between finite element and tests results. The results and observations of subsequent numerical parametric studies offer an insight into the key factors that govern the behaviour of suspension members with bending stiffness in the elastic-plastic range.


Influence identification, one of the compelling applications of Social Network Analysis (SNA) is gaining immense attention in scientific literature analytics. Existing influence identification techniques in the scientific domain majorly explore scientific collaborations (co-author and co-citation networks) of researchers. Standard centrality algorithms are widely applied for this purpose. The emergence of digital scholarly platforms allows researchers to build their social community in the scientific environment. Few scholarly platforms maintain social media like follower and following relations apart from co-authorships and co-citations of researchers. This research examines the impact of followers and followings on influence identification in the scientific domain. The real scientific information from widely utilized digital scholarly platforms: ResearchGate (RG) and Academia is extracted. From the collected information, scholarly networks are constructed based on follower-following relations. Standard centrality algorithms are implemented to identify the influence of these networks. The results are compared with i) the researcher's influence scores provided by RG and Academia ii) three legitimate global ranking lists of researchers. The outcome suggested that, like SNA, social collaborations among researchers in terms of followers and followings significantly impact influence identification in the scientific domain.


Security of national borders requires utilization of multimedia surveillance systems automatically gathering, processing and sharing various data. The paper presents such a system developed for the Maritime Division of the Polish Border Guard within the STRADAR project. The system, apart from providing communication means, gathers data, such as map data from AIS, GPS and radar receivers, videos and photos from camera or audio from phone calls and SMS messages, from multiple mobile units and stationary points located along the coastline. All gathered data can be visualized on a multidisplay by the personnel that can dynamically select presented data and configure form of presentation. The paper describes system functionalities, its hardware and software implementation, and presents results of acceptance tests that the system have recently passed.


http://msj.sagepub.com 1169 This is an extremely relevant topic for a controversy; two experienced multiple sclerosis (MS) clinicians, John Zajicek and Stanley Hawkins, take opposed views. For those who need a short overview of the issues involved in the modern randomised clinical trial (RCT) in MS, I would recommend an excellent paper by Xavier Montalban.1 Those requiring a full exposition of the principles and practicalities of the subject, and considering starting a trial, should consult the comprehensive bible for triallists by Curtis Meinert.2


This thesis reveals the results of the application of thematic webbing model through scientific approach based learning in the public elementary school of Simpang Dua sub-district of Ketapang. The problems of this research focused on how were: the design, process, evaluation, supporting factors and obstacles in the application of the model. The purpose of this research was to describe the design, process, evaluation, and supporting-inhibiting factors. Techniques of data collection were by observation, interviews, and documentation. Data analysis was done by triangulation. The research findings were: (1) thematic lesson plan made by the teacher fulfilled the standard of requirements; (2) the learning was done by the use of thematic webbing model through scientific approach based learning which more involved learners and varied method to support them play active roles in the learning process; (3) the learning evaluation was done by using various assessment instruments, letting the teachers understand the behavior and ability of the learners; (4) the availability of facilities and infrastructure, willingness and ability of the teachers, motivation from the principal and attention of the parents functioned as the supporting factors; (5) the learners' differences in ability and interest in talent were the obstacles in the application of this model.


Based on the principles of OFDM, key technology (Encoding and decoding, synchronization, equalization), and the current transmission system is learnt. Particularly discusses the key technology and its implementation process in detail. On this basis completely based on OFDM transmission of system is designed. In order to meet our performance requirements for the system, we highlight several important part of the transmission system. Modem design, the modem implementation, transmission bus controller design, interface design. Finally, by the analysis of data transmission systems verifies the practical value of the system, and gives directions for further research.


The pendulum effect of the efforts of mankind in any sector can be perceived fairly easily. I recall reviewing this effect some years ago with a student group in regard to dental epidemiology and especially the epidemiology of dental caries. The review recalled the early attempts, which were crude observations of the occurrence of disease without any definable sampling or other methodology. The data reported were, nevertheless, important to our perception of oral disease problems, although the level of importance varied widely according to the common sense of the investigator in seeking to exclude sampling bias and to attain consistency in observation in the absence of a formal methodology. As interest in epidemiology as a science grew and had its effects on the oral health sector, the pendulum swung inexorably away from that extreme toward a proliferation of ever more complex methods of measurement and ever more rigorous sampling schemes. These trends developed instruments of great and fundamental importance to dental epidemiology and provided data which extended and refined our knowledge of the prevalence and incidence of oral diseases. However, they also confused investigators wishing to choose the most appropriate methods. They gave rise to masses of data, which could not be compared because of the wide variation in methodology used, and to high cost surveys, which few could afford. It was in response to this second extreme that the WHO oral epidemiology program became involved in the development of standard methods, particularly for descriptive epidemiology. The program was subdivided into basic methods and those which might be used in follow-up investigative procedures using the epidemiologic process. These methods have been concerned mainly with measurements, but also have dwelt upon the need to use simple and rapid sampling methods, at least in certain circumstances. It is very interesting to note that there has been a remarkable increase in the use of these standard and simple methods, despite a first reaction that they were not sophisticated enough. Also, this acceptance has not been confined to developing countries, as might have been expected, because there is a growing sense of the real needs of oral epidemiology for rapid and repeated data availability at low cost which is constant no matter what the level of development. I shall return to this subject later. To continue the pendulum analogy, it is possible that we are in the midst of a similar sequence in ethical and legal considerations. It was not too lI9ng ago that the prevailing attitude seemed to be that almost anything could be done anywhere, in the name of research. We should not forget that, despite the transgressions of human rights and dignities consequent to such attitudes, much important new information and understanding resulted, just as it did during the early, crude observation stage of epidemiology. Awareness of the ethical and legal requirements of research efforts has grown gradually, and perhaps it has reached, or is reaching, a stage where safeguards could be so complicated and comprehensive as to impede research which mankind needs to maintain or develop a healthy environment. I have approached my task with that situation in mind and will contemplate what should and might happen to the epidemiology of dental caries because of ethical and legal considerations.


Summary

1
Large-scale conservation measures aimed at reducing the abundance of a wild population offer a unique opportunity to study the impacts of human exploitation on demographic parameters. We examined the effects of a spring conservation harvest and liberalized autumn/winter regulations introduced recently to control the rapid population growth of greater snow geese Anser caerulescens atlantica.

2
We predicted that these changes in regulations affected survival and recovery probabilities, as well as kill rates. This was evaluated by analysing data on geese shot by hunters before and after implementation of these measures.

3
Annual survival and recovery probabilities were estimated using likelihood-based ring recovery models, and we developed a new, flexible seasonal model to determine the specific effects of regulation changes made during different hunting seasons. We used harvest survey data to estimate ring-reporting rate, and thus to convert recovery rates into kill rates.

4
Adult recovery and kill rates increased considerably with the implementation of the new measures in 1998–99. The addition of the spring harvest in Quebec and the liberalized winter regulations in the USA had the largest impacts, whereas autumn regulation changes in Quebec apparently had little effect. Juvenile recovery and kill rates also showed a moderate increase, but were highly variable.

5
We observed a decline in mean annual adult survival rate, from 83·0% to 72·5%, although the implementation of conservation measures did not fully explain temporal variation in adult survival; juvenile survival showed no change. Adult survival was negatively related to harvest rate in adults but not in juveniles.

6
Synthesis and applications. We demonstrate that the spring conservation harvest led to a decrease in adult survival and an increase in hunting mortality, and probably contributed to the decline in abundance observed since its implementation. However, regulations during the traditional autumn and winter hunting seasons could also be manipulated for future population control once the spring conservation harvest is discontinued. Our approach for evaluating hunting mortality on a seasonal basis should be useful in the management of other migratory populations that move through several jurisdictions.


New phenolic resins containing titanium and silicon in the main polymer structure were synthesized and some of their properties were investigated. Titanium and silicon contents of the polymers ranged from 2 to 13% titanium and from 2 to 5% silicon. These polymers became insoluble and infusible as the titanium and silicon contents of the products were increased. IR spectra of these modified resins were presented. The thermal oxidative degradations of the phenolic resins modified with titanium and silicon were also investigated using thermogravimetry and differential thermal analysis. Titanium and silicon-modified polymers, showed considerably lower weight changes as compared with those of unmodified or titanium-modified polymers, but the rate of the last oxidative degradation increased and the final degradation temperature decreased with increasing titanium concentration. The best results for the thermal resistance was found to be 2% ≤ Ti ≤ 6% and Si 2–5%.


Equivalent widths of UV silicon lines obtained from high dispersion IUE SWP spectra for a sample of 37 mid- to early B stars are presented. These are compared to other atmospheric diagnostics and to model atmosphere calculations. It is found that some of the UV silicon lines are extremely sensitive to stellar temperature and luminosity over the range B5-B0.5, or roughly a factor of two in effective temperature. The potential usefulness of these lines is stressed, and it is demonstrated that they could determine temperatures and surface gravities to the same accuracy as other commonly used diagnostics once adequate models become available. Although the available models fail to predict the quantitative behavior of the line strengths, they do, in most instances, describe their qualitative behavior. Since the existing models are somewhat out of date, the results suggest that models based upon more complete opacity tables may be quite reliable.


For Advanced Manufacturing Technology teaching problems,we exert some practice and reform on mobilizing students' enthusiasm and improving teaching methods. As a result,the quality of classroom teaching is significantly improved.


Stratix Ⅱ GX FPGA from the Altera Corporation is employed to implement the transmitter module in a 40Gbit/s very short reach optical transmission system. This paper focuses on the design of 16:12 converter. The high speed interface is designed based on the high speed transceiver: At the receiver, two methods are adopted to align the phase of the 17-channel data; at the transmitter, additional synchronization measure is taken to satisfy the demand from the clock management unit (CMU) to the data transmission between asynchronous clock domains, ensuring the stability of the transceiver. On these bases, the clock network is implemented by considering the reliability and the facility of the follow-up testing. Meantime, a frame aligner based on a synchronous digital hierarchy (SDH) structure, as well as the deskew circuit and the 16:12 mapping module is devised, achieving the conversion of data from SFI-5 interface to VSR5 interface; the deskew module can eliminate the skew of 512bits dynamically. The testing results using Signaltap Ⅱ verify the validity of the design. Measured by the Agilent 81250, the errorbit rates also meet the design index of being less than 10^(-12).

A number of CFD (Computational Fluid Dynamics) calculations were carried out to simulate the large scale room corner fire, which is an important scenario for the evaluation of the fire performance of the surface lining material. Considered are turbulent gas flows, turbulent combustion, radiation and heat conduction inside solid boundary. Heat transfer from flame and hot gas is calculated, with the important radiation component presented by discrete transfer (DT) method and the convection heat transfer considered by the wall function. An absorptivity and emissivity model was employed to predict the radiation property of combustion products including soot, CO2 and H2O, which are usually the primary radiating species in the combustion of hydrocarbon fuels. Configurations are a square burner flame in the corner of the standard full scale fire room, with three different standoff distances: 0 cm, 5 cm and 10 cm, and two different burner outputs: 40 kW and 150 ItW. Totally, six cases were studied. The results, including the temperature and heat fluxes, are discussed and compared with experimental measurements. (Less)


Micromagnetics is a nonlocal, nonconvex variational problem. Its minimizer represents the ground state magnetization pattern of a fer-romagnetic body under a speciied external eld. This paper identiies a physically relevant thin lm limit, and shows that the limiting behavior is described by a certain \reduced" variational problem. Our main result is the ?{convergence of suitably scaled 3D micromagnetic problems to a 2D reduced problem; this implies, in particular, convergence of minimizers for any value of the external eld. The reduced problem is degenerate but convex; as a result it determines some (but not all) features of the ground state magnetization pattern in the associated thin lm limit.


The utility model relates to the technical field of a lamp and particularly relates to an LED (Light-Emitting Diode) ceiling lamp. The LED ceiling lamp comprises an outer lamp cover, an inner lamp cover, a reflection cup, an LED light source and a heat radiator, wherein the outer lamp cover and the inner lamp cover are cylinders provided with through holes; the outer lamp cover covers the inner lamp cover; the outer lamp cover and the inner lamp cover are connected through a positioning screw; the reflection cup is located in the inner lamp cover; the lower end of the LED light source is embedded into the top of the reflection cup; the upper end of the LED light source protrudes out of the top of the reflection cup; the lower end of the heat radiator is connected with the upper end of the inner lamp cover in a sleeving mode; a step hole is arranged in the heat radiator; the step hole is matched with the upper end of the LED light source; and the outer wall of the heat radiator is provided with uniform heat radiation fins. According to the utility model, the LED light source is independently located in the heat radiator and the LED ceiling lamp has the advantages of simple structure, good heat radiation effect, long service life for use, and convenience for maintenance.


This study attempted to examine the feasibility of using medical Computerized Tomography (CT) imaging
scanner to monitor the growth of tissue engineered constructs (TECs) in vitro. A preliminary CT examination
was performed on TECs prepared from serially expanded chondrocytes seeded on poly (lactic-co-glycolic
acid) (PLGA) based scaffolds that acted as cell carriers. One day old PLGA with fibrin and cells (PFC),
PLGA and cells (PC) as well as PLGA with Fibrin (PF) constructs were stored in normal saline prior to CT
examination. The kVp used was 80 Kvpwhile the effective mAs was 11 mAs. Sharp kernel was chosen as the
reconstruction parameters and slice thickness used was 0.1mm.A PLGA without cells or fibrin was used as
control. X-ray attenuation of TECs, measured in Hounsfield units (HU) or, also known as CT values were
observed. The results indicated that the control PLGA, the PFC, the PC and also the PF constructs gave CT
values between -665HU to 477HU, between 149HU to 181HU, between -120HU to 263HU and -209HU to
185HU respectively. These initial results indicate that the x-ray absorption-based quantitative differentiation
between TECs could be appreciated. The CT values documented suggest that the differences in attenuation
values are dependent on the condition of the scaffolds or the TECs themselves. Furthermore, the use of
intravascular ultrasound (IVUS) software installed in the CT system was found to be useful in appreciating
the different compositions within the scanned samples. It is hoped that the outcomes of this preliminary study
can serve as a baseline for future research to look for an alternative method to quantitatively monitor the
growth of TECs in vitro as well as in vivo.


The effect of 6 chemical insecticides on conidial germination of Metarhizium anisopliae were tested The results showed that all chemical insecticides inhibited the conidial germination to a certain degree,and the higher the concentration was,the stronger the inhibition was Omethoate inhibited the conidial germination of M anisopliae most poorly The result of a bioassay showed that it was obvious of the synergism against Masson's Pine Caterpillars when M anisopliae (concentration of 1 9×10 10 spores ·L -1 ) mixed with Decamethrin (1∶60 000),or Phoxim (1∶10 000),or Mieshabi (1∶25 000) and or Benzoylphenol Ⅲ (1∶15 000),with LT 50 7,6,5 and 3 days respectively earlier than that of using fungal insecticide of M anisopliae(1 9×10 10 spores ·L -1 ) alone
