PURPOSE: To provide a long sevice life scintillation camera plate assembly to house a sicintillation crystal such as thallium-active sodium iodide by respectively sealing an outer ring, a transparent plate of its front face and a cover plate of a rear face by frit. CONSTITUTION: An outer ring 12 is composed of a front face on which an optically transparent plate 14 is installed and a rear face covered with a cover plate 16, and a circular groove 18 is notched on the front face. The plate 14 is welded or soldered to the outer ring 12 by using frit formed in the shape of a ribbon 22. Grooves 18 and 42 are notched on the rear face of the outer ring 12, and a depth of the groove 42 is slightly larger than a thickness of the plate 16. This groove flows out excessive solder and frit 46 or the like from a scintillation plate of a main body. Distortion of the light on an interface of materials of a different type can be prevented by applying an optical coupler 50 having a refractive index close to a refractive index of the plate 14 to an inside surface of the plate 14.

Objective To establish a method to determine six kinds of PAEs in human serum simultaneously,and on this basis to understand the level of PAEs in human body.Methods Ultrasonic extraction,gas chromatography-mass spectrometry-selected ion monitoring(GC-MS-SIM) detection and quantitative analysis based on internal standard were used to detect six kinds of PAEs in human serum simultaneously.Finally this method was used in fifty human serum samples.Results The results showed that this method had a good linear relation in the range from 10 to 1 000 ng/ml,and the correlation coefficients of standard curve were higher than 0.999.The average recovery rate and the relative standard deviation(RSD,n=6) of the target compounds in standard-addition blank was 94.5% and 4.4% respectively,the lower limits of detection for DEP,DMP,DBP,BBP,DEHP,DNOP were 0.31,0.85,0.90,0.63,0.88,0.41 ng/ml respectively,and the recovery rates of all samples ranged from 67.98% to 110.8%.Conclusion This method has good recovery rate,reproducibility,lower limit of detection and can be used for the determination of many kinds of PAEs substances in human serum.


In the era of King Kwanghaegun in the Joseon Dynasty going through the period of transition from ImJin War(倭亂) into Invasion of the Qing Dynasty (胡亂), the Joseon Dynasty has been trying to prevent and deter a war with Qing(淸, 後金). The purpose of this thesis is to study the military strategy o...


ABSTRACT Amy Tan's The Bonesetter's Daughter is a fictional account of a Chinese American woman and her mother, a first-generation migrant, who is negotiating dementia in later life. Analysis of diasporic novels can provide insight into migrant belonging, especially the emotional geographies of home and emotional subjectivities of ageing that are not commonly or easily elucidated even by qualitative interviewing methods. This article examines Tan's construction of ageing as an intergenerational, cultural and emotional process, and highlights the role of storytelling as an everyday home-making practice through which the transnationality of home in older age becomes evident.


Albumin and pre‐albumin are frequently used as nutritional markers in clinical practice. We examined whether serum albumin and pre‐albumin were predicted by body mass index (BMI), hydration and/or inflammation in female adolescents with a recently diagnosed restrictive eating disorder (RED).


Reducing the energy consumption of coal-fired generator units (CFGN) is an inevitable choice for the transformation of the power industry to low-carbon. Starting from the analysis of the energy consumption evaluation index of CFGN, the main factors affecting the energy consumption of CFGN are analysed. It is proposed that the operation optimization is an important way to reduce the energy consumption of CFGN. From the aspects of hierarchical measurement and reconstruction of process parameters, the establishment of equipment thermodynamic characteristic model, and the determination of benchmark operating conditions, the methods and research status of energy consumption analysis and operation optimization of CFGN are discussed. It is pointed out that the application of data mining information technology is the development direction of CFGN operation optimization.


This chapter is about how living the connected effects of violence situates the argument that domestic violence reverberates across women's lives and erodes their citizenship. A data analysis here reveals the effects of intimate partner violence on the material, emotional, and social aspects of women's lives and how such violence disrupts and restricts their combined capabilities to participate in everyday life, very often for lengthy periods. The chapter offers insights into how women's experiences are shaped by a range of factors, such as state legislation and policy, the resilience or hostility of their own families and communities, and the availability of opportunities to gain and maintain employment. It reveals that women who have experienced violence rarely regain their place on their original life course. The quality of their housing, employment, mental health, and social participation is generally diminished.


With the development of artificial intelligence, computer-aid polyp detection (CAD) systems are proposed as auxiliary detectors. However, CAD systems are generally evaluated from a computer vision perspective, rather than from a practical perspective to evaluate their performance in assisting physicians. One of the reasons is that clinical tests are expensive, and most of the existing available datasets are images, which cannot be used to evaluate the assistance performance. To this end, in this paper, we propose a new colorectal examination video dataset for evaluation, named ToPV, which contains 360 short videos collected during real colonoscopy examination. 204 of the videos contain one polyp and are labeled by experienced endoscopic physicians. Based on ToPV, we also present an experiment scheme for evaluating the assistance performance of CAD systems. The result of the initial experiment shows potential benefits of CAD systems in improving physicians' performance.


Summary An attempt has been made to determine whether the bremsstrahlung from a 20 mev betatron is polarized. The experiment consists essentially of measuring the angular distribution, with respect to the plane of emission of the photons, of photo-protons produced in the photodisintegration of the deuteron. The distribution instead of being purely symmetrical, as would be expected for unpolarized bremsstrahlung, indicates some asymmetry.


Recently there has been significant research efforts towards materials by design, self assembly at various length scales, and functional soft materials. Here, we propose that skyrmions in chiral nematic liquid crystals are suitable building blocks for the realization the above goals due to the possibility of individually controlling them. Skyrmions have attracted much and rapidly growing interest due to their topological properties and unique aspects for potential novel applications such as data storage and soft robotics. While not real particles, these skyrmions behave like particles-they interact with each other and can be actuated by means of electric field, surface anchoring, and light. On the other hand, they are field configurations which have properties not possessed by real particles. In this letter, we outline some of the basic mechanisms and knobs by which LC skyrmions can be confined and moved for realization of custom material properties. Our work may trigger experimental efforts in this direction.


This paper introduces an approach for a more effective thermal protection of overhead electrical lines. Starting from thermal model of overhead line, its thermal behaviour has been simulated resolving thermal balance equation thanks to the dynamic simulation program, MATLAB. Then, knowing simulated behaviour of the conductor, time-current curve has been obtained, that adapts itself, in each simulation interval, to the new working conditions of the line. The knowledge of the real thermal behaviour together with a completely automatic thermal protection could guarantee full exploitation of existing overhead lines without reducing safety and quality.

Treatment with pentobarbital of primary cultured cerebellar granule cells decreased the g-aminobutyric acid, (GABA)A receptor subunit gamma-2 long/short (gamma-2L/S) mRNA ratio. A high dose of pentobarbital (500 mM) decreased the gamma2L/S ratio by 64%; the decrease was dose and time dependent and reversible. (2)-Hexobarbital (500 mM), the less potent stereoisomer for GABAA receptor activation, decreased the ratio slightly (30%) but significantly more than (1)-hexobarbital (20%). Other GABAA receptor activators had no (100 mM ethanol) or little (2 mM 5a-pregnane-3a-ol-20-one) effect on the gamma-2L/S ratio. Furthermore, picrotoxin (10 mM), which blocks the GABAand pentobarbital-activated GABAA receptor channel, neither changed the gamma-2L/S ratio nor blocked the pentobarbital-induced changes. These data suggest that barbiturates alter the gamma-2L/S mRNA ratio by a mechanism that does not require GABAA receptor activation. The gamma2L/S subunit mRNA includes an exon encoding an octapeptide that contains a protein kinase C phosphorylation consensus site. This exon-encoded peptide, occurring in the putative intracellular loop, can be phosphorylated, and in vitro, this phosphorylation has been shown to have functional consequences. This is the first report of a drug-induced alteration in receptor mRNA splicing. Furthermore, the changes in the gamma-2L/S ratio produced by pentobarbital exposure may have significant effects on the function of an important brain protein, the GABAA receptor. The family of GABAA receptors are ligand-gated chloride channels formed from combinations of five of the .13 mammalian receptor subunits (alpha 1–6, beta 1–3, gamma 1–3, delta and rho) in pentameric arrays (Olsen and Tobin, 1990). This multiplicity of subunits provides one basis for the diverse pharmacology of the GABAA receptors (Tyndale et al., 1995b). Further diversity can result from splicing variants of individual receptor subunit mRNAs and intracellular phosphorylation of the GABAA receptor subunits (Lin et al., 1996; Moss et al., 1992b; Swope et al., 1992). We tested the chronic effects of two GABAA receptor agonists on receptor adaptation in primary cultures of cerebellar granule cells. Initially, changes in mRNA for 13 subunits were assessed after chronic treatment. The only major change observed, however, was in the ratio of the long and short forms of mRNA for the gamma-2 subunit. The gamma-2 subunit mRNA exists in two forms, a long form (gamma-2L), whose mRNA contains a 24-nt exon, and a short form (gamma-2S), which does not contain this exon (Whiting et al., 1990; Kofuji et al., 1991). The additional exon of gamma-2L encodes an octapeptide that lies within the putative cytoplasmic domain, between the third and fourth transmembrane regions (Whiting et al., 1990; Kofuji et al., 1991). The octapeptide includes a consensus phosphorylation site for PKC, with a serine in position 343. Inclusion or exclusion of this octapeptide and its phosphorylation site may alter the phosphorylation of the resulting receptor and lead to altered receptor function (Kellenberger et al., 1992; Leidenheimer et al., 1992; Lin et al., 1996; Machu et al., 1993; Moss et al., 1992a, 1992b). Compounds that alter the ratio of gamma2L/S mRNAs may also alter the functional properties of GABAA receptors; therefore, such compounds will enable further exploration of the role of receptor phosphorylation in


The following pages analyse the motivations behind the Russian and Chinese vetoes that prevented three Security Council resolutions from entering into force. In particular, the commonly accepted argument according to which they used their veto power in order to prevent a repetition of the regime change as it happened in Libya will be challenged on various grounds. In particular, it seems that it was not an outright rejection of regime change but rather the frustration of having been left aside during the post-Gaddafi scramble for oil and other economic benefits, that led to their voting behaviour. In addition, Russia almost had no other option than using the veto because of its close ties to the Assad regime. Here, Libya rather created an environment of distrust that compelled Russia to cling on its ally due to the well-grounded fear that a newly-imposed regime would not continue this special relationship.


The report summarizes and analyzes the procedures currently used by all 50 U.S. states, Puerto Rico, the Virgin Islands, and selected foreign countries and international organizations to estimate the costs associated with natural resource damages for spills of oil and hazardous substances. The report focuses on simplified damage assessments which, for the purposes of this study, were defined as a set or sets of standardized procedures requiring minimal field observations and providing reasonable, cost-effective methodologies for establishing and quantifying in monetary terms damages to natural resources incurred as a result of a discharge of oil or a release of hazardous substances.


This paper examines a unique data set based on surveys of 139 compensation executives. Respondents read scenarios describing a hypothetical company and its labor market, and recommended wage changes for several positions. Contrary to some popular theories, differences in unemployment, quit rates, and a company's return on assets led to almost no change in respondents' recommended wage increases. When market wages for closely related occupations diverged, most respondents did not recommend adjusting relative wages within the company; but when the occupations were not closely related (blue versus white collar), most respondents recommended adjusting relative wages to reflect market forces.

Although some indices of social pathology were associated with the proportion of Roman Catholics in the states in a 1980 data set, these associations were confounded by the association of the proportion of Roman Catholics with the proportion of Jews and the urban/wealth characteristics of the states.


COVID-19 is an infectious respiratory disease that the World Health Organization has declared a pandemic. Although a global phenomenon, there is the need to react locally with swift and informed actions, as some of the essential plans are highly dependent on factors such as culture, geography, laws, and customs. This paper presents our approach to mapping the geospatial spread of COVID-19 in Mexico at the state and municipal level, the highest allowed possible resolution in the publicly available dataset provided by the Health Ministry. To visualize the magnitude of the infection, we offer a map for the confirmed positive, pending, and deceases cases, while to support mobility, we provide a geospatial visualization of $R_t$, the basic reproduction number. This document describes the structure of the dataset, the software tools employed, and a description of the functionality of the maps, which definition we make publicly available.


A series of crises in the 21st century is giving a fresh impetus to study the short-term mechanisms of demographic changes. Descriptions of the set of such mechanisms substantially compliment the explanations of fertility changes based on one main mechanism emphasized by theories of second demographic transition or dividend of gender equity. This article compares the mechanisms linking anxiety and uncertainty with fertility in the countries of Visegrad group, Scandinavian countries, and Russia. Unlike Visegrad countries, in which fertility was procyclical from the early 1990s until the late 2010s, in Scandinavian countries recovery after great recession was unexpectedly accompanied by dramatic fertility decline. The most adequate explanations of Scandinavian phenomenon are precarization of the work and the emergence of new source of anxiety associated not so much with current situation as with life prospects. In Russia fluctuations in birth rates from the early 1980s to the mid-2010s were caused by economic busts and booms, and the measures of demographic policy. The low fertility in the very end of the 2010s, running counter upward trend of real wage in this period, introduces new features in this mechanism and, perhaps, has something in common with Scandinavian phenomenon. Studying influence of employment precarization and social media on fertility is important to develop demographic and family policy in Russia.

Security alerts high-level reasoning efforts such as alert filtering and intrusion alert correlation are initiatives to solve security data flooding and high false positive alert rates. These efforts decrease the volume of the security data, marginally reduce the false positive rate, and improve the attack-detection rate. Although the results of these efforts have been encouraging, there are still weaknesses partly due to data quality problems. This paper works on the premise that a quality input data should in theory help in producing good results. Thus, the aim of this paper is to propose an intrusion alert quality framework that addresses alert preparation stage for high-level reasoning by enriching and enhancing the alerts with quality parameters, and then encoding these enriched alerts in the IDMEF format. In this format, the enriched alerts are readily usable by high-level reasoning operations.


While peptide and protein therapeutics have made tremendous advances in clinical treatments over the past few decades, they have been largely hindered by their ability to be effectively delivered to patients. While bolus parenteral injections have become standard clinical practice, they are insufficient to treat diseases that require sustained, local release of therapeutics. Cyclodextrin-based polymers (pCD) have been utilized as a platform to extend the local delivery of small-molecule hydrophobic drugs by leveraging hydrophobic-driven thermodynamic interactions between pCD and payload to extend its release, which has seen success both in vitro and in vivo. Herein, we proposed the novel synthesis of protein-polymer conjugates that are capped with a "high affinity" adamantane. Using bovine serum albumin as a model protein, and anti-interleukin 10 monoclonal antibodies as a functional example, we outline the synthesis of novel protein-polymer conjugates that, when coupled with cyclodextrin delivery platforms, can maintain a sustained release of up to 65 days without largely sacrificing protein structure/function which has significant clinical applications in local antibody-based treatments for immune diseases, cancers, and diabetes.

There is increasing interest in learning environments and the roles they play in medical education. The body of evidence in this area is growing. Learning environments cut across all three aspects of the medical curriculum as we have come to understand it – formal, informal and hidden – although their influence is probably most powerfully felt (but least understood) in the context of this last element. The hidden curriculum is a complex phenomenon, made of many overlapping and interacting parts, and there remains much work to be done to investigate not only the nature of the hidden curriculum, but also the particular effects it may exert on learners.

The use of prototype moulds made with rapid tooling (RT)-techniques offers the possibility to manufacture prototypes in the series process. Although the series material is used during injection moulding, the properties of the prototype are not identical with the product because of the varying surface qualities of the RT-moulds and the different thermal conditions in the process. In this work, different RT-techniques (resin casting, metal spraying, selective laser sintering, investment casting and keltooling) are investigated according to the morphological as well as the mechanical properties of injection-moulded prototypes. The specimen are compared with parts that were injection-moulded in a steel mould to realise a comparison between prototype and product. The thermal diffusivity of the analysed RT-mould materials differs from one tenth of the value of steel up to seven times higher compared to steel. This leads to a different morphology of the prototype concerning the boundary layers and the spherulite size. A good heat conducting materials (e. g. aluminium investment casting mould) causes thick boundary layers and small spherulites. In contrast, a rather insulating mould material (e. g. resin casting mould) results in thin boundary layers and large spherulites. The investigations show that the effect of a good heat conducting material can be achieved by using a lower mould temperature for badly conducting materials in the same way. The yield stress of the prototypes differs up to 20% from the mechanical properties of the product and is influenced by the spherulite size and the mould's surface quality. The prototype, moulded in a keltool mould, shows the best resemblance with the product.

In this paper, we study the fixed charge transportation problem with uncertain variables. The fixed charge transportation problem has two kinds of costs: direct cost and fixed charge. The direct cost is the cost associated with each source-destination pair, and the fixed charge occurs when the transportation activity takes place in the corresponding source-destination pair. The uncertain fixed charge transportation problem is modeled on the basis of uncertainty theory. According to inverse uncertainty distribution, the model can be transformed into a deterministic form. Finally, in order to solve the uncertain fixed charge transportation problem, a numerical example is given to show the application of the model and algorithm.


This study investigates the internal validity of a management simulation game from a cognitive perspective. The results indicate that game participants were unable to determine (i.e., cognitive insight) the nature of the response functions for the demand-generating variables of the game. The internal validity of such a pedagogical tool, therefore, is open to question.


The fossil fuel divestment movement has undergone explosive growth over the last few years - expanding from encouraging educational institutions to adopt ethical investment policies to focusing upon cities, pension funds and philanthropic charities. The fossil fuel divestment movement has attained global ambitions - challenging sovereign wealth funds and national governments to engage in fossil fuel divestment, and pushing for fossil fuel divestment at international climate talks - such as the Paris Climate Summit in 2015.By exploring and analysing a key campaign to 'Divest Norway', this chapter considers the efforts to globalise and internationalise the fossil fuel divestment campaign. Part 1 explores the origins of the fossil fuel divestment movement, and the application of such strategies in a variety of contexts. Part 2 looks at the campaign to divest Norway's sovereign wealth fund of fossil fuel investments. There has been much discussion as to whether the bold decision of Norway to engage in coal divestment will encourage and inspire other sovereign wealth funds to engage in fossil fuel divestment. The conclusion considers the efforts to introduce fossil fuel divestment as a policy initiative for nation states as a policy option in international climate law.


Background The aim of this study was to investigate the association between cyclooxygenase-2 (COX-2) rs689466 (–1195 G>A) polymorphism and susceptibility to head and neck squamous cell carcinoma (HNSCC) by performing a meta-analysis. Material/Methods PubMed and Embase were searched for relevant cohort and case-control studies up to 13 March 2015. After data extraction and methodological quality assessment for eligible studies, the overall, subgroup, sensitivity, and cumulative meta-analyses were conducted using the Comprehensive Meta-Analysis software (version 2.2). Results Finally, 5 case-control studies involving 1564 HNSCC patients and 2346 healthy controls were included. For overall population, the results of 3 genetic models showed significant association, while the other 2 presented negative association [A vs. G: OR=0.97–1.09, 95%CI=0.97–1.09; AA vs. GG: OR=1.26, 95%CI=1.01–1.57; AA vs. GA: OR=1.21, 95%CI=1.01–1.45); AA vs. (GG+GA): OR=1.20, 95%CI=1.01–1.43; (AA+GA) vs. GG: OR=0.98, 95%CI=0.84–1.15]. Publication bias was not assessed due to the limited number of included studies. Conclusions This meta-analysis indicated that COX-2 rs689466 polymorphism might be associated with increased susceptibility to HNSCC. We also suggest performing more relevant studies in order to enlarge the sample size and obtain more precise results.


The U.S. Census Bureau conducts an Economic Census every five years. Besides collecting a set of common items from all eligible establishments, the Economic Census collects detailed information on each establishment's products. Beginning in 2017, the Economic Census will use the North American Product Classification System to produce economy-wide product tabulations from cross-sector collections. This marks a major departure from the current collection – which explicitly links products to industry – and makes the trade-area specific missing data adjustment practices impossible. An interdisciplinary research team was established to address this, and the outcome was the recommendation of a single (unified) methodology for the treatment of missing product data. The team conducted a comprehensive evaluation study using empirical and simulated data from the 2012 and 2007 Economic Census. In all of the studied industries, a form of hot deck imputation appeared to be the best compromise of the considered methods. However, the recommended variation (nearest neighbor or random) was split between trade areas. Consequently, the team investigated whether certain properties of establishments or products might be predictive of one method having better statistical properties than another across different subdomains. Such exploratory analyses readily lend themselves to classification tree analysis. A classification tree starts with a categorical outcome (often binary) and grows branches that represent an explanatory variable. The nodes (splits) at the top of the tree represent the covariates that are most strongly related to predicting outcome. In our application, the outcome was the choice of hot deck method, and the predictors were characteristics of establishment data within the imputation cells. In this paper, we describe how we used classification trees to develop an understanding the underlying causes that led to one method preferable to another and provide some limited guidance for implementation in the 2017 Economic Census and future analyses.

Periprocedural levels of various inflammatory markers have been correlated with prognosis in patients undergoing percutaneous coronary interventions. However, long‐term variations of interleukin‐1 receptor antagonist (IL‐1Ra) or C‐reactive protein (CRP) during follow‐up after coronary interventions were not previously investigated. The aim of our study was to perform serial evaluations of these markers before and after coronary stenting and to correlate them with clinical status. Plasma levels of IL‐1Ra and CRP were measured at baseline and 3 and 6 months after the procedure in 31 patients with symptomatic coronary artery disease undergoing stent implantation, who had no evidence of myocardial ischemia at 6‐month follow‐up. While at 3 months there were no significant variations of baseline values, 6 months after the procedure a significant decrease from baseline was observed both in IL‐1Ra and CRP levels (median −24 pg/ml, P = 0.048, and −0.13 mg/dl, P = 0.017, respectively). Six‐month reduction in both IL‐1Ra and CRP levels was significant in patients with unstable angina (n = 18; IL‐1Ra: from 175 to 119 pg/ml, P = 0.001; CRP: from 0.52 to 0.18 mg/dl, P = 0.002) and nonsignificant in those with stable angina (n = 13) on admission (IL‐1Ra: from 123 to 158 pg/ml, P = 0.22; CRP: from 0.19 to 0.10 mg/dl, P = 0.44). In conclusion, a significant reduction of IL‐1Ra and CRP levels is observed 6 months after stent implantation in patients with preprocedural unstable angina who remain free of ischemia. This decrease suggests a stabilization of the inflammatory process and may be associated with a favorable prognosis after coronary interventions.

This chapter unites together the last four texts of the Āpaddharmaparvan (ĀDhP). These texts continue the transitional function begun by those texts discussed in the last chapter, a transition marking not just a shift from the thematic space of the ĀDhP to the Mokṣadharmaparvan (MDhP), but also a shift from the entire royal instructions constituted in the Rājadharmaparvan (RDhP) and ĀDhP taken collectively to the instructions on the 'laws of liberation' that constitute the MDhP. The transitional texts discussed in this chapter part with those explored in the previous chapter on formal grounds, a formal distinctiveness matched by their quite separate transitional functions. The first of these units offers a long and idiosyncratic exposition of penance, the purificatory practices advocated not only for crimes, but also for the sorts of breaking of normative rules that typifies a time of crisis. The second and third units form a kind of pair.Keywords: Āpaddharmaparvan (ĀDhP); Mokṣadharmaparvan (MDhP); Rājadharmaparvan (RDhP); transitional texts

Background: Radiology plays an essential role in the diagnosis, staging and
surveillance of oncology patients. CT is the most sensitive imaging modality in
the workup of these patients. Aim of the Study: The aim of this work is
to detect the role of MDCT (multidetector computed tomography) in the preoperative
investigation of gastric adenocarcinoma patients according to TNM staging. Patients
and Methods: This is a prospective study enrolling 20 patients who had
histologically proven adenocarcinoma based upon an upper gastrointestinal
endoscopic biopsy for MDCT staging of gastric carcinoma during the period from
June 2016 to June 2017. The MSCT data were correlated and compared with the histopathological
results. The study was conducted in the Radiology Department of Assiut University
Hospital using 64-MDCT (Toshiba Aquilion). Results: According to our study results, the
sensitivity of determining T1 stage on CT scan can't be detected as there was
only 1 case pathologically proved T1 and overstaged as T2 by MSCT; however,
accuracy and specificity are quite high, which was 95% and 100% respectively. For
T2 stage tumors (25.0% of cases), accuracy is 95%, sensitivity—100%, and
specificity—93.7%. According to our results the accuracy and sensitivity of T3
staging are 75% and 100%, while those of T4 stage were 75% and 44.4%
respectively. Tumor was correctly staged in 14 of 20 patients (the valid T
staging rate was 70.0%). Tumor was under-staged in 5 of 20 patients (25.0%)
(staged as T3, but pathologically proven to be T4a). As regards N staging accuracy
found results for N0 (62.5%), N2 (87.5%) and N3 (75%), while N1 accuracy
recorded 37.5%. As regards the nodal staging sensitivity which had a range from
(0% for N4) to (66% for N2) this wide range of sensitivity demonstrates the
problem of CT in nodal staging. As regards sensitivity of M0, accuracy was 100%
and 85% respectively. While that of M1 was (62.5%) and (85%) respectively. Conclusion: MSCT can be the first choice for the preoperative evaluation of patients
with gastric carcinoma. It presents excellent accuracy in the staging of tumor
invasion depth (T) and in the staging of metastatic neoplastic disease (M).
Despite the good accuracy in the staging of patients without lymph node disease
(N0), the method presents limitations in the staging of lymph node involvement.


Financial transfers from relatives can have a large impact on the consumption choices made by households. We develop a Stackelbergtype model wherein the parent who remained at the home location decides on the level of education the child acquires depending on the migrant's remittances and other sources of income. In a repeated game we find equilibria in which the effect of an increase in the remittances has a larger effect on schooling than an increase in other source of income. We test the empirical implications of this model using data from the Republic of Congo.

Purpose To assess the long-term clinical and radiographic outcomes after vertebroplasty using calcium phosphate cement (CPC) for treatment of osteoporotic vertebral fractures (OVF). Overview of Literature Vertebroplasty has become common for the treatment of OVF. However, few studies have reported the clinical application of CPC to vertebroplasty. Methods We reviewed 86 consecutive patients undergoing 99 vertebroplasties using CPC. Following repositioning and curettage of the pathological soft tissue of the vertebral body (VB), vertebroplasty using CPC was performed in patients with osteoporotic burst fracture and pseudoarthrosis (procedure A). Vertebroplasty was also performed in patients with osteoporotic compression fractures (procedure B). Back pain and lower back pain were evaluated using the visual analogue scale (VAS). The VB deformity index was measured in a lateral radiograph as the ratio of the VB's height to its longitudinal diameter. Results The mean age at time of surgery was 77 years old. The mean duration of follow-up was forty-four months. All patients reported decreased pain according to the VAS immediately after vertebroplasty, and pain relief was maintained at the last follow-up in all patients without new OVFs. Complete bone union was observed in all cases by six months after surgery. The mean recovery rate of deformity index was 5.9% in procedure A and 0.02% in procedure B at the final follow-up visit. Conclusions Vertebroplasty using CPC gave a satisfactory outcome and no delayed complications in elderly patients with osteoporotic vertebral fractures at follow-up times of at least two years.

The paper presents the results of a morphometric study of the internal organs of a water deer (Hydropotes inermis Swinhoe 1870) found in the southern part of the Primorsky Krai of Russia. For the first time, the linear and weight parameters were determined, the morphological features of the internal organs of the water deer were described.


The object of the present paper is to obtain certain sufficient conditions for close-to-starlikeness and close-to-convexity of order β . Introduction The function, for which the equation ( ) f z w = has p roots in D for every complex number w , is said to be p -valent (or multivalent) function, where D is a domain in the extended complex plane C . Let H be the class of analytic functions in { 1} U z C z = ∈ :| | , ≤ . Then we have


We investigate changes in the time series characteristics of postwar U.S. inflation. In a model-based analysis the conditional mean of inflation is specified by a long memory autoregressive fractionally integrated moving average process and the conditional variance is modelled by a stochastic volatility process. We develop a Monte Carlo maximum likelihood method to obtain efficient estimates of the parameters using a monthly dataset of core inflation for which we consider different subsamples of varying size. Based on the new modelling framework and the associated estimation technique, we find remarkable changes in the variance, in the order of integration, in the short memory characteristics and in the volatility of volatility.


In this paper we explore different configurations of loop sizes in two-dimensional high temperature superconductor (HTS) Superconducting Quantum Interference Device (SQUID) Arrays. Fixing the number and loop sizes, we changed the placements of the loop sizes to see the effects on the voltage-flux response. We find an asymmetry in the voltage-flux response of the anti- peak feature when the large and small loop sizes are organized on opposite sides of the array. Additionally, we investigate increasing the number of junctions in parallel to mitigate the effects of the junction critical current spread on the voltage-flux response.


Previously believed to be distinct cultivars Malvasia delle Lipari, Malvasia di Sardegna, Greco di Gerace (Italy), Malvasia de Sitges (Spain) and Malvasia dubrovacka (Croatia) displayed an identical molecular profile when analyzed by 15 SSR markers. Ampelographic comparison supports the genetic analysis indicating that they are all the same variety; they do not differ in any important morphological trait. This genotype is scattered all over the Mediterranean area and as far as the Canaries and Madeira. Historical investigation indicates that the genotype has been imported from Greece. However, so far, the search in Greek databases has produced no useful results to confirm this theory. Allele frequency comparison among cultivars from Greece, Croatia, Italy, Spain and Portugal showed that none of these countries can be pinpointed as the 'home country' of this genotype.


824 Incrimination of Blomia tropicalis as a potent allergen in Indian house dust Sanjay Podder, and Goutam Kumar Saha. University of Calcutta, Department of Zoology, Kolkata, India. Allergy to house dust mites particularly to the genus Dermatophagoides is a common feature in tropical climate like Kolkata, India leading to various nasobronchial allergic manifestations. Analysis of house dust samples collected from the houses of the asthmatic patients of Kolkata revealed a variety of acarine fauna of which the mites belonging to the genus Dermatophagoides predominated, comprising 60.4% of the total acarine population followed by Blomia tropicalis (16.6%) and Austroglycyphagus geniculatus (6.8%). Perusal of literature revealed that works on the role of house dust mites in allergic etiology mainly concentrated with the genus Dermatophagoides alone. No work incriminating the role of Blomia tropicalis in house dust allergy has yet been reported from India, although it contributes significantly towards the domestic acarine population. High prevalence of this mite species in the patients` environment tempted us to search for an allergic etiology towards this species of mite. Allergy skin test with house dust and house dust mites revealed an encouraging result against Blomia tropicalis. 72% allergic asthmatics of Kolkata responded positively towards this species of mites. The total serum IgE level in patients varies between 54 to 4040 KU/ ml (mean 369+487 KU/ml). Detection of allergen specific IgE antibodies against this species of mites also confirms its role in house dust allergy. 30% patients showed very high, 20% high and 40% showed moderate IgE level against this mite antigen. The present study incriminates Blomia tropicalis as an important source of allergen in house dust in Indian condition.


The aim of this study is development of SR(steam reforming) catalyst to improve performance of de-NOx catalytic system for DME engines. The SR catalysts (Cu-based) were used r-Al₂O₃ or r-Al₂O₃+Modenite 10% prepared by an impregnation method and the LNT used as a commercial catalyst. As a result of experiments, Cu10%/r-Al₂O₃+modenite 10% showed H₂ production of 58% compared to that of 10% over the Cu10% /r-Al₂O₃ catalyst at 300℃. When H₂ generated by the Cu10%/r-Al₂O₃+modenite 10% catalyst was used as LNT reductant, the NOx conversion was improved by about 15% compared to the LNT used alone.


In an attempt to extend storage life of 'Hass' and 'Fuerte' avocado {Persea americana Mill.) fruit postharvest vapour heat treatments were used. Vapour heat treatment temperature regimes were 36, 38, 40 and 42°C for either 1, 2, 4 or 8 hours. After vapour heat treatment, fruit were cold stored at 3.5°C, for 5 or 6 weeks each. On removal from cold storage fruit were evaluated for firmness, and ripened at room temperature. Once ripe fruit were evaluated for heat/cold damage, days to ripening, weight loss and physiological disorders. These experiments were conducted during the 1996 and 1997 'Fuerte' and 'Hass' avocado seasons. Electron microscope analysis of vapour heat treated fruit revealed heat damage to the epidermis and fruit organelles of certain treatments. The effect of vapour heat treatment on protein synthesis on 'Fuerte' and 'Hass' avocado was investigated using gel electrophoresis, to determine if presumed heat shock proteins were synthesized under the treatment conditions. The activity of pectin methyl esterase was also investigated on the heat treated 'Fuerte' and 'Hass' avocados, to investigate if heat alters the activity of this enzyme. All experiments showed that vapour heat treatment extended 'Fuerte' and 'Hass' avocado storage and shelf life. Evaluation of the time/temperature combination for vapour heat treatment for each cultivar indicated that extension of shelf life was, in some cases, limited by rind heat damage. For the 1996 season, the best time/temperature combination for 'Fuerte' was at 38°C between 4 to 8 hours, 40°C between 4 to 8 hours and 42°C between 2 to 4 hours. For 'Hass', best results were achieved at 38°C between 4 to 8 hours. For the 1997 season, 'Fuerte's best time/temperature combination were at 36°C for 8 hours, 42 °C between 1 to 2 hours and marginal results at 38°C between 4 to 8 hours. For 'Hass' the best time/temperature combination were achieved at 38C and 40°C for 8 hours. Analysis of fruit flesh protein indicated changes associated with vapour heat treatment, and even induction of new proteins, perhaps heat shock proteins, giving 'Fuerte' and 'Hass' avocados beneficial characteristics such as an extension of shelf life. There was a decline in activity of pectin methyl esterase after vapour heat treatment, which was associated with a longer shelf life.

A new method is proposed to detect the number of signals and estimate their directions-of-arrival (DOAs) in the multipath channels. Based on the coherency among signals, multiple independent sources resulted from multipaths are automatically divided into several independent groups from the multistage constant modulus array with power signal detector, and the spatial signature corresponding to each group is estimated. Then the problem for combined detection and estimation is transformed into solving for the coherent signals from each spatial signature and finally handled by utilizing the invariance property of noise subspace. The proposed method not only can deal with the situation where there are more incident signals than sensors in the array, but also is applicable to arbitrary array geometry. Effectiveness of the method is demonstrated by computer simulations and water tank experiments


In this article the concept originality is questioned and it is argued that the translator of cabaret, as sender number two of the message, has to adapt the message for the new communication situation, and that as the 'original' text ages and changes it calls for new translations. Some of Aucamp's translations of Bertolt Brecht are studied in the light of the above and the conclusion is reached that he succeeds in re leasing "in his own language that pure language which is under the spell of another" (Benjamin quoted in Johnston, 1992:44).This article is based on a paper that was read on October, 21 1994 at the "Slegs vir almal' conference that was held at RAU, Johannesburg, to celebrate Aucamp's sixtieth birth day.


Study of the effect of intumescent complex compounds on the basis of aminoderivatives of 2,4,8,10-tetraoxа-3,9-diphosphaspiro[5,5] undecane on the flame retardant properties and water resistance of the ethylene vinyl acetate copolymer in the flame retardant polymer compositions. The structure of intumescent compounds has been confirmed by the methods of elemental analysis and IR spectroscopy, the flame retardant properties of the intumescent systems have been investigated using the method of thermogravimetric analysis. Methods of synthesis of intumescent compounds based on 2,4,8,10-tetraoxа-3,9-diphosphaspiro[5,5]undecane and urea, melamine, dicyandiamidе and mixtures there of have been developed. The synthesized compounds have been shown to enhance the flame retardant properties of the ethylene vinyl acetate copolymer, exhibit an intumescent effect and participate in the construction of a char thermal insulation layer. It has been shown that the water resistance of fire retardant systems with the participation of intumescent complex compounds is much higher than the systems of ammonium polyphosphate / melamine / pentaerythritol composition. The expansion coefficient of intumescent systems containing of intumescent compounds to decrease by 10 - 20% after hydrothermal effects, while, as the expansion coefficient of the traditional intumescent system  in the same conditions is reduced by 40%. According to the results of accelerated hydrothermal tests, the stability of polymeric intumescent coatings with the participation of intumescent complex compounds to the action of moisture under conditions of temperature difference was determined. The obtained results indicate the prospect of using the investigated intumescent compounds for the creation of new technologies of intumescent coatings for wood with a long operation life.

Potential-induced degradation (PID) of Cu(In,Ga)Se2 (CIGS) photovoltaic (PV) modules fabricated from integrated submodules is investigated. PID tests were performed by applying a voltage of −1000 V to connected submodule interconnector ribbons at 85 °C. The normalized energy conversion efficiency of a standard module decreases to 0.2 after the PID test for 14 days. This reveals that CIGS modules suffer PID under this experimental condition. In contrast, a module with non-alkali glass shows no degradation, which implies that the degradation occurs owing to alkali metal ions, e.g., Na+, migrating from the cover glass. The results of dynamic secondary ion mass spectrometry show Na accumulation in the n-ZnO transparent conductive oxide layer of the degraded module. A CIGS PV module with an ionomer (IO) encapsulant instead of a copolymer of ethylene and vinyl acetate shows no degradation. This reveals that the IO encapsulant can prevent PID of CIGS modules. A degraded module can recover from its performance losses by applying +1000 V to connected submodule interconnector ribbons from an Al plate placed on the test module.


Traditional evolutionary algorithms require a lot of memory and processing power on embedded logic projects. Representing populations of candidate solutions through vectors of probabilities rather than sets of bit strings saves memory and processing. The concise evolutionary algorithm (CEA) is a probability vector based evolutionary algorithm. The article presents an FPEA realization of the standard concise evolutionary algorithm with a few changes to improve search power. A data flow and a block diagram design are shown and described in the paper. Results demonstrate the requirements (logical blocks) needed for realization, the architecture processing speed and the solving power of the CEA for Evolutionary Hardware.

Objective: The development of antisocial behavior among youths with histories of sexual aggression was examined. Method: Participants were 1,725 youths and their parents who were part of an ongoing, prospective longitudinal study that followed youths from early adolescence (11 to 17 years of age) through emerging adulthood (18 to 27 years of age). Individual youths completed a self-report delinquency measure in seven waves of the study. Of the participants, 131 individuals reported committing at least one sexually aggressive act across the seven waves, and 605 individuals reported committing at least one serious nonsexual antisocial act (e.g., physical assault, robbery) but no sexual aggression during the study. Results: A growth mixture modeling approach revealed three antisocial behavior trajectories (i.e., low, moderate, and chronic) and indicated that individuals with a history of sexual aggression (i.e., sexual perpetrators) generally did not have different antisocial behavior trajectories during adolescence and emerging adulthood than did individuals with histories of serious nonsexual antisocial behavior (i.e., nonsexual perpetrators). Moreover, similar proportions of sexual perpetrators and nonsexual perpetrators were found on each of the three trajectories. Conclusions: These findings suggest that sexual perpetrators are not a homogeneous population and that the development of problem sexual behavior is generally similar to the development of other serious antisocial behaviors. These findings also suggest that treatments that have demonstrated effectiveness with delinquent youth in general may be successful with sexually aggressive youth in particular.


In this examination of the relations between the sexes, the author argues against sexual stereotyping and the sexual division of labour. She offers a view of a world beyond the age of the Patriarch, in which men and women's equality is based on what is similar in their natures.

Abstract A series of oxo-centered metal carboxylate triangles have been heated to 200–400°C under a stream of N2. The products of this treatment depend on the metal, carboxylate, and counterion present. Heating [Cr3O(O2CC6H4Cl)6(H2O)3][NO3]to 200°C gives a compound that crystallizes as [Cr(OH)(O2CC6H4Cl)2]8 [Cr3O(O2CC6H4Cl)6]2[O2CC6H4Cl], indicating incomplete dehydration of [Cr3O(O2CC6H4Cl)6(H2O)3][NO3] at this temperature. For [Cr3O(O2CCMe3)6][O2CCMe3] heating to 400°C gives a new salt containing the hexanuclear cages [Cr6O2(OH)2(O2CCMe3)11] [Cr6O4(O2CCMe3)11]. For [Mn3O(O2CPh)6(NC5H5)2(H2O)] a reduction of the metal occurs and a polymeric complex [Mn4(O2CPh)8(EtOH)6]n can be crystallized from EtOH.


The recent rapid proliferation of the Internet has been promoting global development of network services. One of the features of the development of our vehicular society is that on-board vehicle terminals are becoming a successor to the human-carried cellular phones. Technological development is being carried on as a national project in Japan to establish information and communication network technology which supports user mobility (called "Smart Gateway" for the future vehicle-road communication system) to implement a variety of information services aimed at safe vehicle driving. This paper proposes a mobile network platform to implement highly reliable communications. The authors propose a mobile access node system by Autonomous Decentralized System (ADS) control to provide multiple radio communication zones as logical service providing cells. This system allows "continuous communication services" (uninterrupted and seamless services using short-range communication among microcells) and provides on-board vehicle terminals with IP services by interworking with the public/wide-area IP network using Dedicated Short Range Communication (DSRC) for mobile access. For the radio access, the microcell mobility management for the short-range radio communication is described. This function provides features of fast packet data transmission in the roadside network system, assurance of the packet data transmission in the network during the handover and the entity authentication between the on-board vehicle terminal and the roadside network system. For the gateway system, IP gateway management is described. This function manages the IP address given to each on-board vehicle terminal to provide the wide-area IP services to on-board vehicle terminals. Finally, the functional mapping for ITS mobile network platform is described.


We observed the appearance of capillary bridges in a granular medium consisting of glass beads after adding small amounts of liquid. We found the initial bridge formation depending on the bead roughness. Furthermore we obtained a statistics for the average number of bridges for randomly packed beads in dependence of the liquid content and were able to find an explanation therefore based on recent models and former experimental data.


Much has been written about how people embraced new religious identities following the collapse of socialist regimes. This article argues that it is also important to consider the perspective of those (sometimes sceptical) people who may be less eager to participate in new, emergent forms of embodied religious practice. In the ethnographic context of post-Yugoslav Serbia, I ask how 'religion' is perceived, constituted, and evaluated from the sidelines. How do local perceptions of what 'religion' is connect – and collide – with wider ethnomoral communities? I make this argument through a close analysis of an interview with a female interlocutor, a woman who – whilst declaring herself to be unambiguously 'Serbian' and 'Orthodox' – is uncertain about the religious transformations that she sees happening around her. Anthropologists must attend to the positionality of people who may feel at once related to and detached from societal transformations, and how they make sense of such changes in their own terms.


In June this year, SARS/National Treasury released the 'epoch making' draft Tax Administration Bill for public comment. This tax Bill steers tax discourse in a very different direction that affects the way in which tax practitioners engage with taxpayers. SAIPA presented its submission to the Standing Committee on Finance. Below is a summary of the submission. The full document can be viewed on the SAIPA website (ww.saipa.co.za).


Evidence theory allows to build a large family of combination operators, based mostly on intersections and unions between the focal elements expressed by the experts, and multiplications and additions on the masses affected to these focal elements. We explore algebraic structures where these operators behave differently, masses being linguistic labels, or focal elements being more, or less, than an union of singletons of a discernment space. In some cases, we have to forget this space and the notion of singleton to place ourselves in the space of possible focal elements. We propose three new structures for linguistic labels, replacing masses. We show how to adapt the theory of evidence to six constrained spaces for the focal elements expressed by the experts.


Major Depressive Disorder is one of the principal causes of disability globally. It is characterized by low self-regard and thoughts of hopelessness. This study aims at analyzing the brain activity during emotional processing in depressed patients. Fifteen adults with a HDRS-17 score of greater than 20 participated in the study. EEG was recorded while viewing two categories of IAPS pictures namely, neutral and high valence high arousal. SAM scale was utilized to find the perceptual emotions of the participants. The behavioral study showed a neutral response for both the sets of pictures. The mean relative power of alpha was observed to be elevated in left frontal region indicating negative emotion. Significant changes in mean relative beta power was observed between high valence high arousal stimuli ($\mathrm{F}3=0.01,\ \mathrm{F}4=0.016,\ \mathrm{F}7=0.013,\ \mathrm{F}8=0.007$) and neutral stimuli ($\mathrm{F}3=0.004,\ \mathrm{F}4=0.005,\ \mathrm{F}7=0.002,\ \mathrm{F}8=0.002$), indicating arousal though it is not perceived. Frontal alpha asymmetry scores, with the significance of $\mathrm{p} < 0.05$, showed withdrawal behavior while viewing the pictures when compared to rest. It is concluded that negative emotion for both neutral and positive stimuli could be a characteristic feature for Major Depressive Disorder.

Subject of this thesis is familiar with methods of eavesdropping the keyboard. This work universally talks about a computer keyboard in the beginning. In the next section followed by a familiarity with keylogging - that is, eavesdropping the keyboard with keylogging software or hardware. In conclusion, there is a reflection about legal aspects of the use of keylogging. The aim of this work is to highlight the danger for users of PCs and other devices using the keyboard as input peripheral. Eavesdropping the keyboard ultimately threatens the privacy, finance, know-how, or other values of keyboard users.


An even order graph G with a perfect matching is k-extendable if for every matching M of size k in G, there exists a perfect matching in G containing all the edges of M. In this note, we estabUsh a necessary and sufficient condition for a graph to be k-extendable in terms of its independence number. All graphs considered in this note are finite, connected, loopless and have no multiple edges. For the most part our notation and terminology follows that of Bondy and Murty [1]. Thus. G is a graph with vertex set V(G), edge set E(G), v(G) vertices. minimum degree ~(G) and independence number ex (G) • For V' ~ V(G). G[V'] denotes the subgraph induced by V'. The join G v H of disjoint graphs G and H is the graph obtained from G v H by Joining each vertex of G to each vertex of H. The number of odd components of a graph G is denoted by o(G). Let G be a simple connected graph on 2n vertices with a perfect matching. For a positive integer k, 1 ~ k ~ n 1. G is t-extendable if for every matching M of size k in G. there exists a perfect matching in G containing all the edges of M. Observe that [ and 'K_ are n.n --Zn k-extendable for all k. 1 ~ k $ n 1. The cycle C 2n of order 2n is Australasian Journal of Combinatorics 1995) I PP .59-65 I-extendable but not 2-extendable. k-extendable graphs have been studied by many authors. An excellent survey is the paper of Plummer [2]. In this note we prove the following theorem: Theorem 1: Let G be a graph on 2n vertices with a(G) ~ n + k 1 and k any positive integer such that ~ ~ k ~ n 2 and n k Is even. Then 2 G Is k-extendable if and only if a(G) ~ n k. Our proof makes use of the following two well-known results. Theorem 2: Tutte's Theorem (see Bondy and Murty [1] p.76) A graph G has a perfect matching if and only if oCG S) ~ lSi. for all S c V(G). c Theorem 3: Dirac's Theorem (see Bondy and Murty [1] p.54) If G 1s a simple graph with v(G) ~ 3 and a(G) ~ then G Is hamiltonian. Our first result provides an upper bound k-extendable graph on 2n vertices whose degree n 2k + 1 for 2 s k s n 1. Lemma 4: If G Is a k-extendable graph on 2n vertIces with n and 2k + it then «CG) ~ n k.


This study aimed to investigate the challenges faced, and strategies adopted by micro-family food businesses (MFFB) in Malaysia and examine the family's role in managing such businesses during the COVID-19 crisis. A qualitative research approach was employed, using semi-structured interviews with MFFB owners. The interviews ceased after six participants, ensuring data saturation and the interpreted data's trustworthiness is explained. The findings revealed that MFFB faced multiple challenges, including a drop in sales, business closure, financial instability, and pressure on fixed costs. Besides, this research captured several unique survival strategies adopted by the MFFB owners, such as generosity towards customers, changes in operation, online advertisements, customer satisfaction surveys, maintaining food quality and prices, initiating takeaway orders, and collaboration with food aggregators. The results indicate that task management, responsibility, and reliance are essential to family-owned businesses as significant business strategies. It implies that family relationships play a significant role in the business's direction and business survival; future directions might compare the results to a larger business capacity. This study sheds light on the role of families in managing MFFB during the COVID-19 pandemic and provides practical implications for policymakers, business owners, and practitioners to support MFFB in overcoming challenges during unexpected adversity. By better understanding the challenges faced and strategies adopted by MFFB, it is anticipated to gain greater insight into how the Malaysian food business can become more resilient in the future.


Christian presence in Armenia predates the establishment of Christianity as the official state religion. The Armenian Apostolic Church claims autocephaly, based on the alleged ministries in Armenia of the apostles Thaddaeus and Bartholomew. Thaddaeus is connected with the early Armenian version of the Syriac Doctrine of Addai, while Bartholomew's cult in Armenia dates from the 7th century. The story of the conversion by Thaddaeus of the late 1st century King Sanatruk, and that of the martyrdom of his daughter Sandukht, probably date from the 4th century.

Objective To compare the expression of Ghrelin in Barrett esophagus and normal squamous epithelium by immunohistochemisty,and evaluate the relationship of the bile reflux and Helicobacter pylori infection with Barrett's esophagus. Methods The biopsies were obtained from 66 BE patients and 30 normal persons,which were confirmed by upper endoscopy and histopathology.The experssion of Ghrelin in biopsy specimens were detected by immunohistochemistry and analyzed by pathoimage analysis software. Results The expression of Ghrelin in BE group was higher than that in control group(t=5.76,P0.05).The expression of Ghrelin in intestinal metaplasia group was higher than that in control group,cardia metaplasia group and gastric metaplasia group.The expression of Ghrelin in gastric metaplasia group was higher than that in cardia metaplasia group and control group;the expression of Ghrelin in cardia metaplasia group was higher than that in the control group(F=22.64,P0.05).The prevalence of bile reflux in intestinal metaplasia group was higher than that in other two groups(χ2=12.61,P0.05).The infection rate of H.pylori in BE group was lower than that in control group(χ2=8.84,P0.05). Conclusion With the increase of mucosa injury,it shows that the different degrees of tissue metaplasia and the expression of Ghrelin increase from the cardia metaplasia to the intestinal metaplasia.Bile reflux is an inpormant factor in the type of histopathology in BE.The infection of H.pylori is one of protective factors for esophagus.


The Blockchain technology will soon be ten years of age. What does not sound a lot in absolute terms is a substantial age in a fast-paced and ever changing technological environment. Large unnoticed by the majority of authors on distributed ledger technologies two alternative technologies have recently emerged: Tangle, and Hashgraph. This article provides an introduction to the three main alternative distributed ledger technologies, Blockchain, Tangle and Hashgraph and yields a high-level comparison.


Human Resource remains neglected in the traditional scheme of management system, but it has gain its due share in Performance Management System, because of its infinite potential for managing and improving performance. It was realized that all other resources are equally available to all such competitors. HR is the only resource which, if made committed, can make the difference and help an organization to gain a competitive edge over others. This paper will make efforts to describe the theoretical aspects of effectiveness of PMS in an organization, review the common problems encountered and challenges while implementing PMS, and provide recommendations for implementing PMS effectively within an organization. The result shows that if implemented effectively performance management system acts as a strategic tool and a powerful foundation for the employees to achieve their aspirations and organizations to achieve their financial goals.


abstract The main objective of the work was to regenerate a cutting fluid HS20 used in the manufacturing of silicon wafers. Centrifugation at ambient temperature is initially considered for the treatment of the cutting fluid HS20. However, the slurry being heavily loaded with mineral colloids, tests conducted following the use of this process, have proved its efficiency to be low. Indeed, the best results for colloidal matter abatement have never exceeded 30%. By contrast, an ultrafiltration through a polyethersulfone membrane with a cutoff of 1 kDa shows excellent efficiency and affinity towards the fluid (HS20) to be considered, allowing its full recovery by maintaining its original cutting fluid characteristics. However, this process does present some drawbacks. A strong resistance to flow across the membrane of up to 60% of the total resistance is observed and a drop in permeation flux of about 90% are observed. Given these results, reinforcement of ultrafiltration, under the same operating conditions...


It has been found that both of the iridium (Ⅰ) complexes, Ir)(AN)(CO)(AN = CHCN, P) and [Ir(AN)(CO), react with to give IrCl(AN)(CO), and [Ir(AN)(CO) dissociates AN to yield Ir in the absence of excess AN added, and Ir$(ClO_4)(CO)(Ph_3P)_2$ reacts with to produce IrCl(CO). It is suggested that the catalytic polymerization of AN with Ir proceeds through the formation of [(CO)Ir(-CH=CHCN)(H)(=CHCN)]Cl followed by the formation of iridium(alkyl)(alkenyl) type complex which undergoes a reductive elimination to produce the polymer of acrylonitrile.


Ralstonia solanacearum has been found in Dutch potato production since 1995. For this reason, comprehensive laboratory tests on seed- and ware-potato production have been carried out in Germany. The amount of tested potato lots has increased fivefold. In 1997, 10678 tests were carried out on seed potatoes and 2351 tests on ware potatoes respectively. In 1996, R. solanacearum was found in five lots in Bayern and in one lot in Brandenburg, and in 1997 only in two ware-potato lots in Bayern. A thorough analysis was carried out to find the source of infection, but it was not possible to identify it clearly. The measures taken were based on the draft Control Directive for brown rot, which will soon be adopted by the Council of the European Union, and were very restrictive for the affected farms. Monitoring of a potato-processing enterprise that had processed an infected lot without permit in 1996 established that R. solanacearum was present in wastewater. This paper discusses the measures taken in Bayern and the risks of further introduction.


The incidence of pediatric idiopathic PAH (IPAH) in Japan was first surveyed in 1996 by the Japanese Society of Pediatric Cardiology and Cardiac Surgery (JSPCCS).1 There were 219 PAH cases in 103 centers among children aged 0–15 years: 131 patients (88%) were 1 year or older and 18 (12%) were younger than 1 year. During a 6-year period 136 patients were evaluated. The male:female ratio was 51:72 (1:1.4). There were 2 periods of peak onset: before the age of 1 year and at approximately 12 years of age. Higher incidences were also seen in the age groups 4–7 years and 9–12 years. However, the large proportions of children who undergo school physical examinations at these times might explain the high percentages of cases (26%) in these age groups. Disease onset was concentrated in the age groups 4–7 (34.5% of cases) and 9–12 years (41.2% of cases); mean (SD) age at onset was 8 years 2 months (3 years 8 months) (n=115). Mean age at first visit to a medical center to seek treatment was 9 years 1 month (4 years 0 months) (n=121), which indicates that the mean interval between disease onset and first medical visit was 1 year 8 months (2 years 10 months) (n=112). This suggests that disease progression was quite slow in many patients. In 7 cases, the patient (6.2%) had family members with PAH: 7 males and 7 females, a ratio of 1:1. This ratio differed from that seen in sporadic cases. In 4 cases the patient had siblings with IPAH: 3 (2 girls and 1 boy) had an older brother with IPAH. In another family, an older sister and a younger brother both had IPAH. There was also 1 case of a mother and son having IPAH. The incidence was approximately 1–2 per 1 million children under the age of 15 years.1 During 2005–2011, the annual JSPCCS survey identified 131 children with IPAH. The annual incidence of IPAH was reported to be approximately 26 out of 17,800,000 (1.49 per 1 million) Japanese children younger than 15 years,2 which is similar to that reported by Barst.3


In this paper a linear prediction technique is developed to separate a partial discharge signal from its echoes in a noisy environment. Based on the correlation which exists between the measuring values of a signal, it is possible to trace the signal. The signal can then be extracted from its echoes or background noise. Since the parameters of the prediction technique are determined by the recorded signal, very good results can be obtained from a noisy composite signal. This procedure can provide a good method to filter a composite signal when conventional methods fail.


This paper quantifies the influence of acoustic excitation of Al2O3 nanoparticles on the pool-boiling performance of R134a/polyolester mixtures on a commercial (Turbo-BII-HP) boiling surface. A nanolubricant with 10 nm diameter Al2O3 nanoparticles at a 5.1% volume fraction in the base polyolester lubricant was mixed with R134a at a 1% mass fraction. The study showed that high-frequency ultrasound at 1 MHz can improve R134a/nanolubricant boiling on a reentrant cavity surface by as much as 44%. This maximum enhancement occurred for an applied power level to the fluid of approximately 6 W and a heat flux of approximately 6.9 kW/m2. Applied power levels larger and smaller than 6 W resulted in smaller boiling heat transfer enhancements. In total, five different applied power levels were studied: 0 W, 4 W, 6 W, 8 W, and 12 W. The largest and smallest enhancement averaged over the tested heat flux range were approximately 12% and 2% for the applied power levels of 6 W and 4 W, respectively. In situ insonation at 1 MHz resulted in an improved dispersion of the nanolubricant on the test surface. An existing pool-boiling model for refrigerant/nanolubricant mixtures was modified to include the effect of acoustic excitation. For heat fluxes greater than 25 kW m−2, the model was within 4.5% of the measured heat flux ratios for mixtures, and the average agreement between measurements and predictions was approximately 1% for all power levels.


ABSTRACT This article finds that the introduction of a rights-based approach in EU transboundary river basin management to remedy observed systemic difficulties and to better achieve legal water quality standards could be a next step in achieving integrated river basin management. However, its effectiveness largely depends on the willingness of member states to share river basin districts to subordinate their separate socio-economic interests to ecological needs, as well as to grant a clear mandate and partly transfer responsibilities and powers to a competent supranational authority.

Since 2014, stony coral tissue loss disease (SCTLD) has led to large-scale mortality of over 20 coral species throughout the Florida Reef Tract. In 2019, in-water disease intervention strategies were implemented to treat affected corals. Two treatment strategies were employed: (1) topical application of an amoxicillin paste directly to disease margins, and (2) application of a chlorinated epoxy to disease margins as well as an adjacent "disease break" trench. Effectiveness of treatments on 2,379 lesions from 725 corals representing five species was evaluated using mixed effects logistic regression models which demonstrated substantially greater effectiveness of amoxicillin compared to chlorine-treated lesions across all species up to 3 months post-treatment. As a result of the failed chlorinated epoxy treatments, any new lesions that appeared during subsequent monitoring events were treated with amoxicillin paste, and all corals were monitored and treated as needed approximately every 2 months for up to 24 months. The health status of 1664 amoxicillin-treated corals during each monitoring event was used to model the probability of a coral being uninfected over time. Models included species and geographic regions as variables. The appearance of new lesions (reinfection rates) varied by species, and offshore sites showed greater reinfection rates than inshore sites; however, all sites and species exhibited a decreased probability of reinfection with time since initial treatment. We conclude that topical amoxicillin treatments are highly effective at halting SCTLD lesions and that through initial and follow-up treatments as needed, colonies and reef sites will progress toward a lower prevalence of SCTLD.


Ochratoxin A (OTA) is a common contaminant of cereals and other commodities of animal and vegetable origin all round the world. Its nephrotoxic and carcinogenic properties are well established in experimental animals. Beans (Phaseolus vulgaris) are common food in our country, especially in winter period, but the data on OTA contamination of beans are rather scarce. The aim of this study was to analyze the OTA concentration in naturally contaminated beans with a more sensitive method than in previous studies. During fall 2001, bean samples (N = 45) were collected in 13 counties of Croatia and stored (-20°C) until analyzed. Samples were cleaned up by means of immunoaffinity columns (OchraTest, Vicam) and OTA analyses were performed on HPLC (Varian, USA) with fluorescence detection. Standard curve prepared from OTA-spiked samples in the concentration range 0.25 to 5.0 Ag/kg was linear (r2 = 0.9982). Detection limit of method was 0.25 Ag/kg, reproducibility (day to day precision) expressed as RSD was 5.5%. Such a low detection limit enabled the detection of OTA in 42% of analyzed bean samples in the range of 0.25 to 0.92 Ag/kg. The mean OTA concentration in positive samples was 0.39 F 0.21 Ag/kg (mean F SD). Such a low concentration of OTA in beans does not represent a significant origin of human exposure to OTA, but due to the very long half-life of OTA in humans (35.55 days), it may contribute to the exposure to OTA from other commodities.


Are carried out researches on easing a radio-frequency signal distributed in a wood from RFID labels to the scanner. It is revealed, that wood of various breeds differently influences dispersion of electromagnetic energy. Character and size of dispersion depends on weather conditions and seasons. It is connected with properties of wood and structure of a tree — a surface of a tree trunk, a version of a bark of a tree, a crone with quantity(amount) of branches and leaves or needles of needles. Such concept, as the volume fraction of the wood environment influencing complex dielectric permeability is used. The model of a radio channel in wood linen and the formula for modelling interaction from radio-frequency signal UVCH and SVCH of waves with wood flat is offered. Researches were spent on frequencies of 0,9 and 2,4 GHz for information technologies at monitoring a wood.

Growth hormone (GH)-secretion in HIV-lipodystrophy is impaired; however, GH-sensitivity of GH-target tissues remains to be evaluated. We measured overnight fasting concentrations of GH-sensitive insulin-like growth-factor-I (IGF-I) and IGF binding protein-3 (IGFBP-3) including GH binding protein (GHBP), a marker of GH-receptor sensitivity, in antiretroviral treated HIV-infected patients with (LIPO) and without lipodystrophy (NONLIPO) and antiretroviral naïve HIV-infected patients (NAÏVE). Three h GH-suppression tests using oral glucose were undertaken to determine dynamics of GH-secretion. IGF-I and IGFBP-3 were increased in LIPO compared with NONLIPO (p<0.05), but did not differ significantly between NONLIPO and NAÏVE. Area under the curve of GH (AUC-GH) during the GH-suppression test was decreased in LIPO compared with NONLIPO (p<0.05). Ratio of limb to trunk fat, which was decreased in LIPO compared to NONLIPO and NAÏVE (p<0.001), correlated positively with AUC-GH and rebound-GH (p<0.05). All groups displayed suppression of GH during the suppression test (p<0.05) and all groups, except LIPO, displayed a rebound of GH (p<0.05), which probably is explained by persistently increased plasma glucose in LIPO compared with NONLIPO and NAÏVE (p<0.01). GHBP was inversely correlated with AUC-GH (p<0.01). Our data suggest that GH-target tissues in LIPO are at least as GH-sensitive as in HIV-infected patients without lipodystrophy.

Variations of the Circle of Willis (CW) are not rare in population, some with clinical implica- tions. Th e study was carried out with the aim to assess prevalence of variations of CW using magnetic reso- nance (MR) time-of-fl ight angiography. In this paper we focused only on the anterior portion of CW. Total of 1000 consecutively performed 1.5T cerebral MR angiographies were analyzed retrospectively, regardless of age, sex and basic pathology. Classic type of CW was found in 643 (64.3%) patients, 113 (11.3%) had variations of the anterior portion of CW, 244 (24.4%) of posterior, and 34 (3.4%) had associated anoma- lies. Unilateral hypoplasia of A1 segment of anterior cerebral artery (ACA) was found in 24 (2.4%), unilat- eral aplasia of A1 of ACA in 29 (2.9%), ayzgos ACA in 28 (2.8%), bihemispheric ACA in 14 (1.4%), triple A2 of ACA in 13 (1.3%) and fenestrations of ACA in 5 (0.5%) patients. Th e results of the survey are in line with data reported in other radiological and hystological studies. Clinical implications of these anatomical variations remain unclear, and require further investigation.


Clara Volintiru looks at the recent indictment of Romania's former prime minister on corruption charges. Whilst it is undoubtedly positive to pursue justice for corrupt politicians, there is a dilemma in how to tackle corruption and other sources of institutional mistrust, when questionable and selective prosecutions may reinforce this distrust.

The flipped classroom is one of the recent innovations applied in teaching science concepts to nursing students. It is thought that a more engaging and meaningful learning environment is created, but how exactly this is achieved in flipped classroom is unclear. The aims of this paper are to describe how a flipped classroom was effectively created for beginning off-campus nursing students studying the course Human Body, and to determine its impact on the learning experience of these students. Survey methodology was used to evaluate students' perceptions about flipped classroom. A 15item questionnaire was administered to participants at the conclusion of the course. They were requested to rate or complete thirteen statements on a Likert scale relating to their learning experience and respond to two open-ended questions on what they liked most about the class and areas for improvement. Forty-one (n=41) students completed the post-flipped classroom survey, out of a total of 174 offcampus students for a 24% response rate. Though constrained with poor response, this study illustrated that the flipped classroom was a feasible learning and teaching approach for off-campus nursing students. For various reasons, 84% of respondents preferred the flipped classroom and 85% recommended it for future students.


Compressional magnetohydrodynamic waves detected in the magnetosphere and at ground stations in the Pc3-4 frequency range (f 10‐50 mHz) are generally believed to be generated upstream of the Earth's bow-shock in reflected proton beams and are conventionally considered to be a dayside phenomenon. An analysis of case events reveals that such wave activity is simultaneously detected at very high latitudes in Antarctica (both in the morning and midnight sector) as well as at low latitude in the northern hemisphere in the dayside sector. It reveals that the observed ground activity was ubiquitously determined, by the same upstream activity, even on field lines stretched into the geomagnetic tail.


Wind power generation is considered an effective way for ships to harness wind energy, and the aerodynamic characteristics of wind turbines determine wind energy utilization and efficiency. However, traditional vertical axis wind turbines have intermediate shafts and support rods, which result in large negative effects in the research of the wind turbine aerodynamic characteristics. To address this issue, a Straight-Bladed Vertical Axis Wind Turbine (SB-VAWT) without intermediate support axes is proposed. The turbine can flexibly change the number of blades, rotor diameter, and installation position of blades. The static aerodynamic performance of the wind turbine with different combinations was tested in a wind tunnel laboratory at 10 m/s. The results show that the radius of the wind turbine has a greater effect on the drag coefficient for the same number of blades, with an inverse relationship between the drag coefficient and radius, and a positive association between lift coefficient, static torque coefficient, and radius. The drag coefficient is proportional to the number of blades at the same radius, while the static torque coefficient is inversely proportional to the number of blades. According to the results, placing the initial location in the azimuth range between 30° and 50° can obtain the maximum initial starting torque. Moreover, a wind turbine with a radius of 16 cm can achieve a higher average torque. Changes in the number of blades can significantly impact turbine properties, resulting in wind turbines with distinct features.
