A Fourier-Hermite Study of Dissipation in 1+1-D Models of Fusion Plasmas

This study investigates dissipation in fusion plasmas confined by strong magnetic fields, as described by 5-D gyrokinetic theory. We first derive a reduced model for the dynamics parallel to the magnetic field in both physical and velocity spaces. This model closely resembles the classic one-dimensional Vlasov-Poisson system, but replaces Poisson’s law with the quasineutrality condition relevant to multi-species fusion plasmas. We construct a numerical model using a truncated Fourier-Hermite representation, validate it against existing results for the Vlasov-Poisson system, and then apply it to fusion plasmas. Similarities and differences between the classic and fusion cases are assessed. We then investigate the effect of unsteady forcing by a neutral particle beam, representing both an actual tokamak energy source and a model for turbulence in the omitted dimensions perpendicular to the magnetic field. We find that even small amplitude forcing may substantially affect the long-time behavior, which may have important consequences in the design of efficient fusion reactors.
A STUDY ON THE PATIENTS WITH SCABIES IN KOREA

This study was conducted to understand the status of scabies infection and its epidemic characteristics in the Korean hospitals. 43 hospitals (86.0%) received the reports of scabies infection with suspicious or definite diagnosis to infection control department, implicating continuous increases 14.6% (7/48), 20.8% (10/48), 35.7% (17/48), 44.1% (21/48), and 56.7% (27/48) in 2010 to 2013 and 35.7% (17/48) in 2014 up to April. 92.0% of the hospitals had the rules and guideline of scabies infection control, which seemed to be prepared by the recent certifications of medical institutions and establishment of rules in infection control departments. However, less than half of the hospitals 44.0% (22/50) prepared the screening system related to scabies during the admission processes of the patients, 56.7% of the patients had the typical symptoms related to scabies when they admitted with 47.0% of pruritus, requiring the system to prevent from the scabies epidemic beforehand.
The mechanical properties of the expandable polyurethane resin based on its volumetric expansion nature

Abstract. The expandable polyurethane resin is an innovative material used in the field of soil stabilization and foundation restoration. The injection technology using the expandable polyurethane resin is an effective way that raises the foundations rapidly, strengthening the soil beneath. Nevertheless, different technical aspects have not been studied yet, which might affect the lifting and stabilization process, such as the density of the resin formed in the massive of the injected soils. The density of the resin formed in the massive of the injected soils during the injection process is varied due to the expansion nature of the resin when mixed proportionally controlled by the amount of the injected resin, the injection pressure, the injection temperature, and other factors. Obviously, the differences in resin densities lead to a variation of the resin mechanical properties; consequently, it affects the desired lifting and strengthening results gained. The article demonstrates the results of a laboratory experiment that has been conducted to investigate the mechanical properties of an expandable polyurethane resin consists of two components based on its volumetric expansion ratios controlled by the amount of the injectable resin. The density of the resin gained for each expansion ratio has been obtained and given in this article. The stress-strain diagrams of the resin for various densities and expanding ratios are incorporated. The results were interpreted, and the strength-density relationship of the resin has been established and introduced.
FACTORS AFFECTING INTENTIONS TO USE CREDIT CARDS IN VIETNAM: AN EMPIRICAL RESEARCH BASED ON UTAUT

Disciplinary: Management Sciences (Business Management and Banking). ©2020 INT TRANS J ENG MANAG SCI TECH. INTRODUCTION 1. The year 2020 is a landmark in the history of 70 years since the first credit card was first issued. After seven decades, credit cards have been popularized worldwide and recognized as a payment method without cash. Together with this positive influence, credit cards also help boost the economy. According to Moody’s Analytics (2016), more use of credit card gives a 0.1% cumulative rise in global GDP which equals a $74 billion contribution to yearly GDP. This popularity rocketed in the U.S, one of the biggest markets. TransUnion (2016) reported that the use of credit and debit card reached a peak in the U.S, where nearly 79% of consumers use credit cards. However, the mentioned data could only reveal half of the story so it is necessary to investigate other emerging markets in the East and Southeast Asia. According to World Bank figures in 2017, in Southeast Asian countries like Indonesia, the Philippines, Thailand and Vietnam, credit card ownership still languishes at single-digit percentages. ©2020 International Transaction Journal of Engineering, Management, & Applied Sciences & Technologies
High stakes testing and its impact on students and schools in Hong Kong: What we have learned from the PISA studies

Using data from the first two cycles of the Programme for International Student Assessment, PISA 2000 and PISA 2003, this paper argues that there is no significant relationship between the use of assessments and learning outcomes in Hong Kong. On the contrary, using assessment for tracking students showed negative effect on achievement. Moreover, students use a significant amount of time on homework and tutoring after normal school hours. Since students are very anxious about their academic performances, they tend to be highly competitive and avoid collaboration in their learning, and consequently Hong Kong students suffer from low self esteem and very high anxiety level even though they perform well in many international studies
Antioxidant and Cytotoxic Activity of Phellinus Mushrooms from Northeast Thailand

Background and objectives: Phellinus belongs to the family of Hymenochaetaceae. In Traditional Chinese Medicine, it has been used as an ingredient for the treatment of different types of cancer, ischemia and skin diseases for thousands of years. The present study was aimed to evaluate and compare the mushroom constituents (total phenolic and flavonoid contents) and antioxidant and cytotoxic effect against cholangiocarcinoma cells. Methods: The samples of Phellinus mushrooms including P. igniarius, P.lineteus and P.nigricans were prepared in two ways: macerated in 95% ethanol and decocted in distilled water. The antioxidant activity of the six extracts were evaluated using the DPPH, ABTS and FRAP assays. Total phenolics and flavonoids were determined using colorimetric tests. In addition, cytotoxic activities against cholangiocarcinoma cell lines (KKU-100 & KKU213A) were assessed by the SRB assay. Results: All ethanol extracts of samples showed significantly stronger antioxidant activity compared to aqueous extracts (p <0.05), while the ethanol extracts contained higher total phenolic and flavonoid contents. Phellinus linteus showed the highest antioxidant activity and total phenolic content when compared to P. igniarius and P. nigricans. All samples showed high cytotoxicity against cholangiocarcinoma cell lines, particularly the ethanol extract of P. linteus. The cytotoxicity was correlated to the phytochemical contents and antioxidant activity of each Phellinus mushroom. Conclusions: The cytotoxicity and antioxidant activity are in proportion to the phenolic and flavonoid contents. Therefore, the antioxidant capacity of the mushroom extracts may advocate anti-cancer effects.
Prevalence and associated risk factor of low back pain among medical student of Umm Al-Qura University, Makkah, Saudi Arabia: Cross-sectional study

Background: Low back pain is an incredibly Complaint experienced by different individuals ages. In 2015, the worldwide point commonness of movement constraining low back torment was 7.3%, suggesting that 540 million individuals were influenced at any one time. Low back pain is a symptom, not a disease, and can result from a few diverse known or obscure irregularities or sicknesses. It is characterized by the area of agony, regularly between the lower rib edges and the butt cheek creases. Aim: To determine the prevalence of low-back pain and explore factors associated with MSP among medical students at Umm Al-Qura4 University Saudi Arabia.

Effects of letrozole alone or letrozole in combination with low-dose intramuscular injection of human menopausal gonadotropin on ovulation and pregnancy of 150 patients with polycystic ovary syndrome

Background: Objective of the study was to explore the effects of letrozole (LE) in combination with low-dose intramuscular injection of human menopausal gonadotropin (HMG) on the ovulation induction and pregnancy of patients with polycystic ovary syndrome (PCOS). Methods: The study comprised of 150 couples who were randomly divided into two groups of 75 each. Group “A” received letrozole (LE) in a dose of 2.5 mg to 5mg /d. LE was started orally starting on 3rd to 5th day of menstrual cycle for 5 consecutive days. Group “B” received letrozole in a dose of 2.5 to 5 mg/day starting on the 3rd to 5th day of menstrual cycle for 5 consecutive days. Starting from the day of oral administration of letrozole, 75 IU HMG was injected intramuscularly on alternate days for 5 consecutive doses. The ovulation induction parameters and pregnancy outcomes were observed.Results: The Group A (LE group) had the most completed cycle (310 cycles), 157 (52.3%) of which had ovulation. The Group B (LE+HMG) group completed the fewest cycles (258 cycles), with 168 (65.1%) of them ovulating. This difference was statistically significant (P<0.05). On HCG injection day, both the endometrial thickness (11.5±1.2) and number of mature follicles (2.1±1.3) of the Group B were significantly higher than those of Group A (P<0.001), but the follicle diameters were similar (P>0.05) The pregnancy rate of the Group B was 54.7%, which was significantly higher than that of the Group A (29.3 %) (P<0.05) The average medication cycle of the Group B group was significantly shorter than that of the Group A (P<0.05). Conclusions: The regimen using LE in combination with low-dose intramuscular injection of HMG has satisfactory therapeutic effects on ovulation induction, short medication cycle and high clinical pregnancy rate, which is promising for treating patients with PCOS infertility.
A Window to L2 Learners' Requests to Faculty in Instant Text-Based Communication

Online chat applications have become increasingly popular with the new generation of L2 learners. These new technologies are used for entertainment as well as communication. In spite of incremental pragmatic studies devoted specifically to analyze requests, little is known about L2 learners' requests to faculty in instant text-based communication. As L2 learners lack a clear instruction for mitigating their requests in instant textbased communication like WhatsApp, the present study aimed to examine the pragmalinguistic features of graduate students' requests to faculty on WhatsApp. Furthermore, attempts have been made to determine the writing features of graduate students' requests. The data were a natural corpus of 196 requests written by Iranian graduate students to their professor on WhatsApp, which were coded and analyzed qualitatively. Findings suggest that conventionally indirect strategies were the most prominent request strategies favored by graduate students. Analysis of alerters indicated that the participants mostly used formal address terms. Furthermore, external and internal modifiers were combined in the participants' requests. Analyses of their writing features revealed that the participants tended to use short sentences. In addition, the quality of punctuation and capitalization was relatively poor. Findings bear pedagogical implications for L2 learners, teachers, and course designers.
REASSESSMENT OF THE CATALYTIC ACTIVITY AND SUBSTRATE SPECIFICITY OF FKBP35 FROM Plasmodium knowlesi USING PROTEASE-FREE ASSAY

FK506-binding protein35 of Plasmodium knowlesi (Pk-FKBP35) is a member of peptidyl prolyl cis-trans isomerase (PPIase) and is considered as a promising avenue of antimalarial drug target development. This protein is organized into the N-terminal domain responsible for PPIase catalytic activity followed and the tetratricopeptide repeat domain for its dimerization. The protease-coupling and protease-free assays are known to be the common methods for investigating the catalytic properties of PPIase. Earlier, the protease-coupling assay was used to confirm the catalytic activity of Pk-FKBP35 in accelerating cis-trans isomerization of the peptide substrate. This report is aimed to re-assess the catalytic and substrate specificity of Pk-FKBP35 using an alternative method of a protease-free assay. The result indicated that while Pk-FKBP35 theoretically contained many possible cleavage sites of chymotrypsin, experimentally, the catalytic domain was relatively stable from chymotrypsin. Furthermore, under protease-free assay, Pk-FKBP35 also demonstrated remarkable PPIase catalytic activity with kcat/KM of 4.5 + 0.13 × 105 M−1 s−1, while the kcat/KM of active site mutant of D55A is 0.81 + 0.05 × 105 M−1 s−1. These values were considered comparable to kcat/KM obtained from the protease-coupling assay. Interestingly, the substrate specificities of Pk-FKBP35 obtained from both methods are also similar, with the preference of Pk-FKBP35 towards Xaa at P1 position was Leu>Phe>Lys>Trp>Val>Ile>His>Asp>Ala>Gln>Glu. Altogether, we proposed that protease-free and protease-coupling assays arereliable for Pk-FKBP35.
Incarceration experience at older ages. Does employment protect against recidivism?

We investigate whether employment protects against and/or postpones recidivism among older males who committed their first crime late in life. We employ a multi-state model and difference-in-differences approach, and contribute to the literature by reporting a causal relationship, as we are able to differentiate between those men who were (treated) and were not (control) employed after incarceration. We use administrative data on the entire set of older males in Poland who had their first conviction late in life, had all of their incarceration spells between 2004 and 2017, and were registered with a public employment office thereafter. The sample covers 34,401 individuals, 44% of whom were employed at least once during the analysed period. Of the men in the sample, 97% were working in routine manual occupations. Our study indicates that among these men, employment affected the likelihood of recidivism, and postponed recidivism. The effect of employment on the risk of reincarceration depended on the number of imprisonment spells the individual had. However, the effect we found also depended on the method used. The results of the multi-state model indicated that employment reduced the risk of recidivism by 7% for those who were at risk of a second incarceration. On the other hand, employment increased the probability of subsequent recidivism by 8-10% for those who were at risk of a third or fourth incarceration. These results suggest that institutional interventions should seek to increase the labour market attachment of former prisoners, and, in particular, should focus on ex-offenders with only one conviction, as being attached to the labour force seems to matter more the fewer imprisonment spells an individual has experienced.

Effect of supply chain planning of liquid nitrogen and frozen semen on the quality of animal breeding public services in the selected cattle corridor districts of Uganda

*Corresponding Email Author: chlaguu@gmail.com The study aimed to explain the effect of supply chain planning of liquid nitrogen and frozen semen on the quality of animal breeding public services in the selected cattle corridor districts (Mbarara, Mubende, Luwero and Soroti) of Uganda. The research filled the gap of supply chain planning in ensuring proficient and viable supply of animal breeding inputs from supply chain points of view compared to the traditional core science orientation which tend to focus on the biological processes of reproductive technologies. The study adopted cross-sectional survey design embracing both qualitative and quantitative approaches. Data was captured using structured questionnaires, review of records, focus group discussions (FGDs) and key informant interviews (KIIs) for farmers, staff of the National Animal Genetic Resources and Data Bank (NAGRC&DB), artificial insemination (AI) technicians, and Field Extension workers. The study points to gender disparity as a key concern at household levels when it comes to land and animal ownership. The study established that there was positive relationship between planning (χ2=4.270; p=0.039; χcritical=3.841) and animal breeding services in selected cattle corridor districts of Uganda. The study recommends that genetic centres to put in place systems for coordinated and integrated planning to facilitate outreach for AI services in Uganda.
A TORUS MODEL CONTAINING A SLIDING WELL-MIXED ZONE AS A WAY TO REPRESENT MIXING PROCESS AT UNSTEADY STIRRING CONDITIONS IN AGITATED VESSELS

ABSTRACT This article investigates the modeling of mixing phenomena occur at unsteady stirring conditions in that agitated vessels. In particular, a new model of a torus reactor including a well-mixed zone and a transport zone is proposed. The originality of the arrangement of ideal reactors developed here is due to the time-dependent location of the boundaries between the two zones. This concept is applied to a model of the positive influence of unsteady stirring condition on a homogenization process; the model avoids mass balance discontinuity during the transitions from steady to unsteady stirring conditions. To ascertain the reliability of the model proposed, experimental runs with highly viscous fluids have been carried out in an agitated tank. The impeller used is a nonstandard helical ribbon impeller, fitted with an anchor at the bottom. The degree of homogeneity in the tank is recorded using a conductivity method after a tracer injection. It is shown that, for a given agitated fluid and mixing system, the parameters of the model are easy to estimate and that modeling results are in close agreement with experimental ones. Moreover, it appears that this model allows the easy derivation of the control law, which is a great advantage when optimizing the dynamics of a mixing process.

Should zoo foods be coati chopped?

Article history: Received: 23 Jun 2017 Accepted: 28 Dec 2017 Published online: 31 Jan 2018 Abstract The process of chopping food for zoo animals is common in many zoos, but few studies have evaluated the benefits. While the perceived benefits of chopped diets include reduced food aggression, it is acknowledged that chopping food is time consuming for keepers and increases the risk of desiccation and contamination. Given the potential disadvantages of chopped diets, there is a need to evaluate food presentation in a range of zoo-housed species. To investigate the possible effects on ring-tailed coati (Nasua nasua) behaviour, meals were provided as either chopped or whole for a group housed at Beale Wildlife Park, UK. Effects of food presentation were monitored, with particular attention paid to aggression, allo-grooming, food manipulation and activity levels. Surprisingly, analysis revealed a significant decrease in aggression (P=0.046) and a significant increase in food manipulation behaviours (P<0.001) when whole foods were given. Levels of inactivity were not significantly affected by food presentation technique. These results suggest that chopped food may not provide the presumed behavioural benefits in coatis, and that whole food diets may in fact provide greater opportunities to express natural food manipulation behaviours. Whole food may also decrease aggression levels observed during mealtimes. Chopped versus whole food studies are recommended in other zoo taxa to evaluate the behavioural effects of food presentation.
