Oxygen effect and adaptation reactions of cells. Report 5. Limited use of Eh and pO/sub 2/ as quantitative indicators of modification of radiosensitivity

In this work a quantitative analysis of tissue oxygen tension and redox potential, Eh, in relation to radiosensitivity modified by gas hypoxia and certain pharmacological agents was conducted. Male mice were exposed to total-body gamma radiation for the experiments. Oxygen tension was determined in subcutaneous tissue, bone marrow, and spleen by the polarographic method. Eh was measured by the electrometry method in subcutaneous tissue using standard methods with platinum electrodes. The radioprotective agents used were 2,3-aminopropylaminoethylthiophosphate and guanylthiourea.
Effects of Dietary Supplementation of Fumaric Acid on Growth Performance, Blood Hematological and Biochemical Profile of Broiler Chickens Exposed to Chronic Heat Stress

25/July/2019 Approved: 10/December/2019 ABSTRACT The aim of this study was to investigate the effects of dietary fumaric acid (FA) on the growth performance, hematological parameters and serum biochemistry in broilers under heat stress (HS) condition. A total number of 200 broilers were allocated to five treatments including the thermoneutral group, which was reared at standard ambient temperature and fed basal diet (CONT) and four heat-stressed groups, which were held at 32 ± 1ºC aged from 22 to 42 days and fed the basal diet supplemented with 0, 5, 10 and 15 g/kg FA, respectively. On day 42, body weight and feed intake were measured and feed conversion ratio was calculated. Blood was collected for the estimation of hematological and biochemical parameters. HS impaired the growth performance, but the addition of FA made a higher final body weight, average daily gain and European broiler index in comparison with HS group. The hemoglobin concentration and packed cell volume of HS broilers were significantly lower than those of the CONT birds. Birds administered 5g/kg FA diet had significantly ( p< 0.05) higher erythrocyte counts and hemoglobin concentration compared with birds in the HS group fed basal diet. Also, the HS group exhibited significant increase in glucose, triglyceride, total cholesterol, low-density lipoprotein cholesterol and creatinine when compared with CONT group. Dietary 5g/kg FA increased the serum total protein, albumin, globulin, total cholesterol, high-density lipoprotein cholesterol in comparison with the HS group. In conclusion, this study demonstrated the importance of using FA as feed additives to improve the growth performance of heat-stressed broilers through haematological
THE IMPACT OF INTERNATIONAL STUDENT MOBILITY ON ENTREPRENEURIAL ATTITUDE

The Erasmus international mobility programme represent a significant step in a student’s development. In the past decades, millions of European students gained experience and lifelong learning period from prestigious universities abroad. Erasmus students are seen as independent people, curious about cultures and languages, open to new ideas and especially predisposed to become entrepreneurs. This study was designed to identify the entrepreneurial attitude of Erasmus students in order to ascertain the contribution of international mobility. For this purpose, the expectations of international students who benefited from the Erasmus Plus Programme were compared to the level of satisfaction after completing the international mobility programme at Institute of Business Administration (IAE), University of Sophia Antipolis, Nice. Factors that most influenced students’ departure in Erasmus mobility are academic and professional opportunities abroad. The data for this study was collected using a questionnaire and sent in collaboration with International Relations Office of IAE Nice. The results indicate that international mobility had a high impact on student’s self-confidence and relational skills. Regarding professional and social life, the entrepreneurial attitude was increased by the Erasmus experience.
Product Market Competition and CEO Pay Benchmarking

This chapter examines the impact of product market competition on the benchmarking of a CEO’s compensation to their counterparts in peer companies. Using a large sample of US firms, we find a significantly greater effect of CEO pay benchmarking in more competitive industries than in less competitive industries. Using three proxies for managerial talent that have been used by Albuquerque et al. (2013), we find that CEO benchmarking is more pronounced in competitive markets wherein managerial talent is more valuable. This suggests that pay benchmarking and product market competition are complements. The above results are not due to industry homogeneity.
Taxonomic status of trichodina heterodentata Duncan, 1977 (Ciliophora: Peritrichia) using standard morphology, as well as molecular techniques

Trichodina heterodentata was first described from fish breeding farms in the Philippines by Bryan Duncan in 1977 as ectoparasites of imported cichlids, more specifically the southern African Oreochromis mossambicus from the Limpopo River System. This trichodinid has subsequently been described from almost every continent, bar North America. This cosmopolitan species, with a seeming preference for cichlid hosts, has unambiguous morphological features, but with distinct variances between and within populations. After reviewing previous descriptions from North American trichodinids, analysing the morphological data (both generally published information along with the original type from the Smithsonian Museum) and investigating the distribution patterns of the southern African introduced O. mossambicus throughout the North American water systems, it seems likely that three of the four trichodinids investigated are all synonyms of T. heterodentata. Trichodina hypsilepis Wellborn, 1967, T. salmincola Wellborn, 1967 and T. vallata Wellborn were very similar, while T. funduli Wellborn, 1967 differed quite substantially. This not only annihilates several North American trichodinid species, but also probably indicates an insidious African alien introduction sneaking its way into this continent.
Awareness of Systemic Lupus Erythematosus among General Population in Abha, KSA

Introduction: Systemic lupus erythematosus (SLE)), or lupus, is an autoimmune disease in which a person's immune system attacks various organs or cells of the body, causing damage and dysfunction. It is one of the worldwide autoimmune disorder that has a significant mortality and morbidity. Objective: The current study aims to assess knowledge regarding SLE among the general population in Abha city, Aseer region, KSA. Methodology: Descriptive cross-sectional study was used. Sample: A total of 405 individuals were selected using a simple sampling technique. Selected participant was interviewed using a questionnaire which consisted of many parts dealing with all aspects of SLE (risk factors, diagnosis, management, and prognosis). Data were entered and analyzed by using SPSS. Relevant statistical tests were used according and considered significant if values were less than 5% Results: A total of 405 individuals were involved in this study. Age ranged between 18-55 years, 58% were females. More than one third ( 39.3%) had good knowledge of SLE particularly general and treatment aspects (54%,42%) respectively. The higher knowledge level about SLE was Found among younger participants (below 35 years) than among older (46.9% vs. 30.3%) with statistical significance (P<0.05) which is clearly showed in our results Conclusion and recommendations: This study revealed that the knowledge about SLE among participants was inadequate particularly among less educated, there are so many misconceptions about essential information of these serious diseases which need public health education using different methods including new social media. The comprehensive national study is suggested to explore the knowledge about SLE
High beta diversity among small islands is due to environmental heterogeneity rather than ecological drift

Both ecological drift and environmental heterogeneity can produce high beta diversity among communities, but only the effect of drift is expected to be enhanced in communities of small size. Few studies have explicitly tested the influence of community size on patterns of beta diversity. Here we applied a series of analyses aimed at testing the influence of drift versus environmental heterogeneity on beta diversity among tree communities on islands of variable size.
“You can be my coach, but I am the one in charge” An interpretative phenomenological analysis of the importance of the coach-athlete relationship in Norwegian super-elite athletes

The purpose of this study was to explore the meaning of the coach-athlete relationship for two Norwegian male super-elite athletes. By means of semi-structured interviews and the use of Interpretative Phenomenological Analysis (IPA) the results revealed four emergent themes that represent underlying dynamics that influenced the athletes’ perception of what constitute an effective coach-athlete relationship; 1) Extreme independence. 2) Coaching without skills? 3) The coach as a butler, and 4) Expectations – make it or break it. These underlying dynamics are further discussed using the theoretical frameworks of coping strategies and power with the need for control as an important common denominator.
Lightweight Attention Module for Deep Learning on Classification and Segmentation of 3-D Point Clouds

Research on classification and segmentation of 3-D point clouds using deep learning methods has become a hot topic in emerging applications, such as autonomous driving, augmented reality, and indoor navigation. However, as the complexity of the network structures increases, the computational efficiency reduces, which affects the practical applications of these methods. In addition, prior researchers mostly seek to enhance the quality of spatial encodings, while the channel relationships are ignored. It makes the feature learning of point clouds insufficient, which will reduce the accuracy of classification and segmentation. In this article, a lightweight attention module (LAM) is proposed to improve the computational efficiency and accuracy at the same time by adopting a novel convolution mode and introducing a new attention mechanism based on channelwise statistical features. As the submodules of LAM, the lightweight module and the attention module can also be used independently to focus on improving the computational efficiency and accuracy, respectively, according to the actual applications. LAM and its submodules can be easily integrated into state-of-the-art deep learning methods on classification and segmentation of 3-D point clouds. The experimental results show that the proposed modules have a good performance on benchmark data sets.
International Student Recruitment, Retention, and Transfer Efforts at Top Community Colleges Hosting International Students in the United States

INTERNATIONAL STUDENT RECRUITMENT, RETENTION, AND TRANSFER EFFORTS AT TOP COMMUNITY COLLEGES HOSTING INTERNATIONAL STUDENTS IN THE UNITED STATES Alejandra Diaz-Rangel Old Dominion University, 2020 Director: Dr. Chris R. Glass The number of international students enrolled at community colleges across the U.S. has significantly shifted in recent years. As a result, higher education institutions across the country have developed and integrated rationales for attracting and retaining international students to their campuses. The purpose of this research study was to examine international student recruitment, retention, and transfer efforts taking place at community colleges in the U.S. The data that influence the international student recruitment, retention, and transfer plans set forth by community colleges in the U.S. was collected from decision makers at 15 U.S. higher education institutions through the means of a single-case study research design. This qualitative research design gathered the data through semi-structured, face-to-face interviews conducted during the fall of 2019 and the spring of 2020. Once collected, the data revealed the recruitment, retention, and transfer rates of international students at community colleges in the U.S. The limitations of this study derived from the specificity of the research design since only decision makers at 15 higher education institutions in the U.S. were interviewed. Interested audiences may include higher education administrators, faculty, staff, students, researchers, academic advisors, recruiting agents, policy makers, and governmental officials seeking to expand the presence of international students in community colleges in the U.S and those who are interested in globalization and international education.
‘Felt security’ as a means of facilitating imagery rescripting in psychosis: a clinical protocol and illustrative case study

Abstract People with psychosis do not have routine access to trauma-focused cognitive behavioural therapy (CBT) interventions such as imagery rescripting (IR), partly due to clinical caution. This case study describes the use of a simple imagery task designed to engender ‘felt security’, as a means of facilitating IR with a woman struggling with distressing memory intrusions, linked to her voices and paranoia. We assessed the impact of the felt security task, which was used before IR to enable Kip to engage in reprocessing of her trauma memories, and again after IR so that she would leave sessions feeling safe. The brief imagery task was effective in improving felt security before IR sessions. Felt security then reduced during IR, when distressing material was recalled and reprocessed, and increased again when the task was repeated. It is not yet clear whether trauma-focused interventions such as IR need to be routinely adapted for people with psychosis. In the event that individuals express concerns about IR, if the person’s formulation indicates that high levels of arousal may trigger an exacerbation of voices, paranoia or risk, or where clinicians are otherwise concerned about interventions likely to increase emotional arousal in the short term, the felt security task may facilitate safe and effective reprocessing of trauma memories. This in turn may increase access to trauma-focused CBT for people with psychosis. Key learning aims (1) To understand that people with psychosis need access to trauma-focused CBT. (2) To be familiar with a simple attachment-based imagery task designed to foster ‘felt security’. (3) To learn that this task may facilitate imagery rescripting in people with psychosis.

Examination of Pre-Service Teachers’ Stress Levels towards Academic Expectations and Goal Commitment in Terms of Various Variables

This study was carried out with the aim of examining the stress levels towards academic expectations and goal commitment of pre-service teachers (students who are not yet teaching professionally) in terms of various variables. The data were obtained from pre-service teachers (n=465) studying at a public university. In this study, two scales were used to collect data. One was the Academic Expectations Stress Inventory developed by Ang and Huan (2006) and adapted to Turkish by Akin, Abaci, and Cetin (2009). The other was the Goal Commitment Scale developed by Hollenbeck, Klein, O'Leary, and Wright (1989) in 9 items, revised in 5 items by Klein, Wesson, Hollenbeck, Wright, and DeShon (2001) and later adapted to Turkish by Senol and Turan (2019). Descriptive statistics, Independent T-test, One Way ANOVA, Pearson Correlation and Simple Linear Regression were used in the analysis of the data. As a result of the analysis, significant differences were found in the variable of the department in terms of “expectations of self” and “goal commitment” of pre-service teachers. Similarly, significant differences were found in the variable of academic grade average in terms of “expectations of self”. In addition, it was observed that goal commitment levels and stress levels of “expectations of parents/teachers” of pre-service teachers were high. At the same time, it was observed that the stress level of “expectations of self” of pre-service teachers was above the middle level, but close to the high level.
A comparative study on some biological constituents in serum during normal and silent estrous cycles of crossbred cows of Assam

For the present study a total of twenty normal cyclic and twenty confirmed silent estrous cows yielding 8 – 20 liters of milk were selected at random. Blood samples were collected from each animal on day 0, 10, 17 and 20 (day 0 of the next cycle) and each sample was analyzed for estimation of calcium, inorganic phosphorus, magnesium, zinc, total protein, glucose and cholesterol by using quality kits. The analysis of variance revealed that mean level of serum calcium, zinc, total protein, and glucose differ highly significant (p< 0.01) between different days of estrous cycle in both silent and normal estrous cows. While serum inorganic phosphorus and cholesterol did not differ significantly while serum magnesium differed significantly (p< 0.05) between different days but all above differed highly significant (p< 0.01) among different days of estrous cycle in silent and normal estrus cows.
An extensive comparison of CB-SEM and PLS-SEM for reliability and validity

Article history: Received: July 20, 2020 Received in revised format: August 29, 2020 Accepted: September 12, 2020 Available online: September 12, 2020 Structural Equation Modeling (SEM) includes measurement and structural model for hypothesis testing. The results yielded from structural model is unlikely to be valid if a poor loading of an indicator is selected. The impact of these erroneous result on standardized loading is disregard. Thus, knowing how poor loading can affect the validity of measurement model is a crucial issue. This paper attempts to compare the standardized loadings result between two prominent SEM methods (CBSEM and PLS-SEM) using three varied of simulation models (TRA, Loyalty and UTAUT model) to investigate their effects on reliability and validity of measurement model. The data for each model were generated using R software by setting the value of standardized loading and the construct correlations (N=50, 100, 200 and 500). The value of standardized loadings was set to 0.60 for each construct in the model while the construct correlations were set in the range between 0.45 to 0.65. Then, the AMOS 21.0 and ADANCO 2.0 were used to perform the statistical analysis. It shows that good standardized loading can increase the reliability and validity of construct representation. CBSEM is particularly yielded valid and unbiased estimation under confirmatory condition (established theory) compared with PLS-SEM. The results are illustrated with empirical examples. This paper provides updated evidence about CBSEM and PLS-SEM when assessing the measurement model. © 2020 by the authors; licensee Growing Science, Canada.
Incidence of Salmonella species in Table Eggs and some Egg-based Products

The incidence of Salmonella species was determined in 1050 eggs including balady hen’s eggs, farm hen’s eggs and duck’s eggs (350 eggs each represented by 70 samples as every 5 eggs constitute one sample) and in 90 samples of egg-based products including mayonnaise, cream cake and custard (30 each) were collected from different localities in Assiut city, Egypt. Salmonella was recovered from 8.58, 5.72% of balady hen’s egg shells using Xylose Lysine Deoxycholate (XLD) agar and Salmonella Shigella (SS) agar, respectively and could be isolated from egg content in a percentage of 1.43% by XLD agar. Different serotypes of Salmonella were isolated from shells of balady hen’s eggs including S. typhimurium, S. anatum, S. infantis, S. kentucky while, S. enteritidis was the only serotype that recovered from both shell and content. In case of farm hen’s eggs, S. kentucky and S. infantis could be identified from positive shell and content samples, respectively at same percentage of 1.43% by using XLD agar. On the other hand, Salmonella could not be detected on SS agar from both shell and content of all examined samples. Concerning duck’s eggs 4.29 and 1.43% of shell samples were contaminated with Salmonella by using XLD and SS, respectively. While, 2.86 and 1.43% of examined egg content samples were positive using XLD and SS agar, respectively and S. typhimurium was the predominant serotype which isolated from both shell and content samples. While, S. infantis was recovered from shell only and S. kentucky was isolated from content only. Salmonella species were existed in 2 (6.66%) and 1 sample (3.33%) of the examined cream cake using XLD and SS agar, respectively while, none of the examined custard and mayonnaise samples were positive for Salmonella on both media. S. kentucky, S. shubra and S. enteritidis were isolated from the positive cream cake samples with an equal incidence of 3.33 % for each. Although XLD agar was found to be comparatively better in recovering Salmonella species than SS agar, the two media were found to be complementary to each other for recovering different Salmonella serotypes. Detection of common invA gene in all isolated Salmonella serotypes by PCR assay showed positive amplification of 284 bp fragment specific for the invA gene with total percentage of 100%. Screening of 12 isolates of S. typhimurium and S. enteritidis, which were the most prevalent serotypes in the positive samples for stn, hilA and fimH virulence genes by multiplex PCR revealed varying distribution pattern. The public health hazards and the recommended measures required to prevent contamination of eggs and its based products by Salmonella were discussed.
Timing of cholecystectomy in the treatment of mild acute biliary pancreatitis

Aim: In this study, we aimed to compare the results of emergency and elective cholecystectomy in patients admitted due to acute biliary pancreatitis. Material and Methods: A total of 632 patients admitted due to acute biliary pancreatitis were retrospectively evalauted. Patients with Ranson ≥ 3 and hour 48 CRP > 15 were considered as severe pancreatitis and excluded from the study. Patients were divided into two groups. Group 1 consisted of the patients who underwent emergency cholecystectomy after 48 hours, while Group 2 included the patients who underwent interval cholecystectomy. Results: A total of 386 patients were enrolled in the study. Group 1 consisted of 214 patients. The mean Ranson score was found as 1.3±0.9 in Group 1 and 0.92±0.7 in Group 2. A total of 148 patients in Group 1 and 117 patients in Group 2 had comorbidity (p=0.81). Conversion was performed in 8 patients in Group 1 and 5 patients in Group 2 (p = 0.78). Bile duct injury was not detected in either group. Among the patients in the interval cholecystectomy group, 7 patients were admitted to the hospital due to acute pancreatitits and total 13 patients due to biliopancreatic reasons during the interval period. Conclusion: No effect of cholecystectomy timing was detected on the conversion rates and development of complications. However, development of recurrence and related complications in the waiting period of the patients could be prevented by performing early cholecystectomy.
