Can Virtual Reality Increases Students Interest in Computational Chemistry Course? A Review

Computational chemistry is one of the branches in chemistry that implies the finding of theoretical chemistry into efficient computer programming to monitor, calculate and examine the properties of molecules and solids, adopting these programs to real chemical problems. Intersection between virtual reality (VR) and computational chemistry would bring the strength and improve the weakness of the system for better chemistry field discovery among scholars that level up the educational development. Thus, introduction of VR as an educational medium will eventually add another new technical skill for good purpose mainly for processing data and information. This paper reviews the role of VR as a teaching device in computational chemistry courses. The innovation in teaching and learning helps students to collect more reliable and quality data on the chemical analysis that is not available from the experimental works. This will provide source and bridge for the students to easily collect and analyse data in comprehensive understanding especially deep explanation at atomic level. This teaching strategy also stimulate and attract the interest of the students to be more joyful and native in learning.
GENERATING ORIENTED GRAPHS BY MEANS OF TEAM COMPARISONS

Two teams A and B can be compared by matching each player in A against each player in B. We say that A > B if and only if the players of A collectively win more games against players of B than they lose. If there are n teams Tlf T2, , Tn, then the outcomes of the matches between the various teams may be represented by an oriented graph Hn on n nodes in which an arc goes from the i-th node to the j-th node if and only if T; > Tj. It is shown that any oriented graph can be generated in this way, and that the minimum number of players necessary to generate any oriented graph Hn is of the order of nzllog n. If A = {au α2, , ar} and B = {bl9 δ2, , b8} are two nonempty finite sets of real numbers, we say A > B if and only if the number of solutions of a{ > bj exceeds the number of solutions of α* 1. ) The results of these matches may be represented by an oriented graph Hn on n nodes tl9t2, , tn in which an arc goes from ^ to td if and only if T{ > T3. For example, the teams 2\ = {6, 7, 2}, Γ2 = {1, 5, 9}, and T3 = {8, 3, 4} generate the graph if3 shown in Figure 1.
Job Satisfaction among Ophthalmologists in Iran

Abstract Purpose To estimate the level of job satisfaction among ophthalmologists in Iran and determine the associated factors that may impact their overall job satisfaction. Methods In this cross-sectional study, 181 ophthalmologists (79.0% male) were interviewed by the Warr-Cook-Wall questionnaire with 7-point-Likert scale, which transformed responses from a 0 (most dissatisfied) to 100 (most satisfied). Questionnaires were randomly distributed among registered ophthalmologists at the 29 th Annual Congress of the Iranian Society of Ophthalmology in November 2019. Satisfaction under each scale was considered as a score of > 60% of the total score. Results A total of 181 ophthalmologists with a mean age of 47.8 ± 12.1 years and 16 ± 12 years of practice participated in the present study. They were mostly satisfied with their job as a whole (88.1%, mean score: 60.6 ± 20.7) and dissatisfied with their income (55.9%, mean score: 47.6 ± 20.3). High levels of job satisfaction was found among ophthalmologists with longer duration of practice (P < 0.001) while lower levels of satisfaction were identified among those who worked in academic centers (P = 0.004). Conclusion In this study,high levels of job satisfaction were found among ophthalmologists with longer duration of practice while low levels of satisfaction were identified among ophthalmologists who worked in academic centers. The factors of salary and working hours accounted for the least levels of job satisfaction.
Fluxes of Heat and Vapor in the Lower Atmosphere Derived from Aircraft Observations

Abstract Measurements from aircraft of temperature, mixing ratio and vertical air velocity have been corrected on the basis of zero flux of mass through the flight path to yield fluxes of heat and water vapor at different levels in the lower atmosphere. A detailed examination of these fluxes indicates that most of the heat is carried by eddies much smaller than the thermals which are the obvious features of the temperature records, though the relative importance of the smaller eddies decreases with increasing height. The observed changes in temperature and mixing ratio are compared with values computed from eddy and radiation flux divergences and horizontal gradients and advection.
The Influence of Sharia Compliance and Islamic Corporate Governance on Fraud

This study aims to determine Islamic Corporate Governance (ICG) and Sharia Compliance against Fraud on Islamic Banks in Indonesia. The Independent variable used is Islamic Corporate Governance (ICG) and Sharia Compliance with Islamic Income Ratio (IsIR), Profit Sharing Ratio (PSR), and Zakat Performing Ratio (ZPR) as the proxy. In contrast, the dependent variable used is Fraud. The population in this study are all Islamic Banks (BUS) registered in Bank Indonesia in the period 2016 to 2019. The sample was selected using the purposive sampling method. Samples used in this study were 8 Islamic Banks with a 4-year study period. The analytical method used in this study is data panel regression with the help of e-views 10. The result of this study indicates that the Islamic Corporate Governance (ICG), Islamic Income Ratio (IsIR), and Profit-Sharing Ratio (PSR) are significant effects on the Fraud of Islamic Banks. At the same time, Zakat Performing Ratio (ZPR) did not affect the Fraud of Islamic Banks.
Communicating Inclusion: How Men and Women Perceive Interpersonal Versus Organizational Gender Equality Messages

Interpersonal allyship may serve as a justice cue to signal that an environment is fair to women without increasing men's expectations of anti-male bias. We investigated how exposure to justice cues communicated at the interpersonal and organizational level impact men's and women's perceptions of procedural justice and fairness at an organization. Men and women were asked to imagine working at one of three randomly assigned male-dominated workplaces. Women who imagined working with a White man who was a gender-equality ally (Study 1, N = 352, and Study 2, N = 488) perceived the organization as more procedurally just, identified more strongly with the organization, and were less likely to view their gender as a disadvantage compared to women who imagined a workplace with an organizational diversity statement (Study 2 only) or a control workplace with no justice cues. Men did not view the ally nor the diversity statement negatively in either study. Integrative data analysis revealed medium to large effects (Cohen's d range .74–1.30) across dependent measures included in both studies. Our results suggest that interpersonal allyship from men is a practical way to promote women's expectations of fair treatment without increasing the threat of anti-male bias among men.

Patient-Level Cost Estimation for Health Services at Secondary Hospital, Saudi Arabia

Cost information can help to improve the quality of medical care budgeting, and it can also improve the efficient allocation of resources and patient outcomes. The objective of this study was to estimate the inpatient unit cost of healthcare services in a secondary hospital in Saudi Arabia. A cross-sectional retrospective approach was applied to categorize the inpatients discharged from the hospital from January to December 2018. A top-down costing method for cost estimation was used. We found that the overhead cost center holds 40.17% of the total hospital cost, and intermediate and final care cost centers consumed 25.50% and 34.33%, respectively. Among inpatients wards, the Surgical ward had the highest operational cost (39.27%). Human resources consumed the hospital's highest resources (75%) on salaries. The hospital's cost structure was not remarkable and needs revolutionary changes to adopt the new payment mechanism envisioned in the 2030 Saudi vision.
Examining the Factors Influencing Rural Citizens Adoption Towards Electronic Government Applications: A Descriptive Analysis

This study is a descriptive study to examine factors influencing rural citizens adoption towards electronic government (E-government) applications. With the objective of E-government services is to provide convenience for their consumers, still consumers preferred to choose the counter instead of the E-government applications. With this scenario occurring at the moment, this study exploring the Diffusion of Innovation (DOI) as a factor that influencing rural citizens adoption towards E-government applications. Adopting survey research, the questionnaires for this study was adapted from several previous studies. Applying a descriptive analysis, respondents for this study were selected conveniently among E-government rural citizens users. Based on the 202 respondents was participated in this study, the findings indicated that complexity, compatibility, relative advantage and image were found to be the factors influencing rural citizens adoption towards electronic government applications. Since respondents located in the rural area, perhaps they noticed that E-government application can improve image within their community or within their organization.
Penetration of Hypervelocity Projectile into Foamed Polystyrene

Spherical nylon projectiles 7 mm in diameter and 0.213 g in mass penetrated into foamed polystyrene targets of nominal densities of 11 kg/m3 (L-type), 37 kg/m3 (M-type), and 74 kg/m3 (H-type), at velocities of up to 4.3 km/s. The hole depth takes a broad maximum around the impact velocity of approximately 3.9, 1.8 and 1.5 km/s for L-type, M-type, and H-type targets, respectively, above which the fragmentation of the projectile occurs. Using L-type targets, more than 86% of the projectile mass at the impact velocity of 3.88 km/s is recovered without fragmentation. Maximum penetration depth, maximum cross-sectional area of the hole, and the target mass removed in the penetration are given as a function of the impact velocity Vi and target density ρt and expressed as ∼ρt-1.2, ∼Vi+2.2, and ∼E+1.1 (E: Kinetic energy of the projectile), respectively. The latter relationship suggests that a constant proportion of the initial energy is expended to create the hole.
Negative Sentiment Toward Recent Migrants in a Post-Colonial City: A Case Study in Hong Kong

By examining negative sentiment toward recent migrants among local residents in Hong Kong, this study fills a research gap in understanding group relations between migrants and local residents in post-colonial societies. We suggest that negative sentiments toward recent migrants among local residents in Hong Kong are the result of the society's post-colonial development, which has fostered a local identity and defined a group boundary between residents born in Hong Kong and migrants from the mainland. Linking post-colonial literature with literature on group boundaries, group threats, and scapegoating, we developed four hypotheses to explain the negative sentiments of local residents toward Chinese migrants. Using findings from data collected in 2014, we show that having close friends from mainland China, having higher income, and level of job satisfaction are all related to the level of negative sentiment toward mainland migrants in Hong Kong. Implications of the findings are discussed.
Managerial skills required for new community public health graduates during the COVID-19 pandemic: Employers’ perspective

Abstract Employers claim managerial skills are more important for community public health students than specialist subject knowledge. However, to date, there is no valid and reliable instrument to measure these skills. Furthermore, employers’ viewpoints are often not considered in developing such a measure. This study aimed to develop an instrument by considering employers’ perspectives in health agencies to define the required managerial skills new graduates should possess. A cross-sectional study was conducted during the COVID-19 pandemic. A preliminary list of skills was developed based on the Delphi technique. The final list was then distributed to 410 employers who provided feedback. Exploratory and confirmatory factor analysis was employed to analyze the responses. The employers identified 19 items that indicate four types of managerial skills students need to possess: (a) vision-grounded skill, (b) collaboration skill, (c) systems thinking skill, and (d) health promotion and disease prevention skill. Each skill has a Cronbach’s alpha coefficient ranging from 0.87 to 0.94. The ability to collaborate is the most crucial skill. The limited but valid and reliable tool is relevant in the Thai context because a few instruments are already measuring “competency” or “leadership” skills of community public health professionals. Educators and employers should prepare new practitioners with the four managerial skills identified in the study to perform their jobs effectively.
A Novel Global Prototype-Based Node Embedding Technique

Node embedding refers to learning or generating low-dimensional representations for nodes in a given graph. In the era of big data and large graphs, there has been a growing interest in node embedding across a wide range of applications, ranging from social media to healthcare. Numerous research efforts have been invested in searching for node embeddings that maximally preserve the associated graph properties. However, each embedding technique has its own limitations. This paper presents a method for generating deep neural node embeddings that encode dissimilarity scores between pairs of nodes with the help of prototype nodes spread throughout the target graph. The proposed technique is adaptable to various notions of dissimilarity and yields efficient embeddings capable of estimating the dissimilarity between any two pairs of nodes in a graph. We compare our technique against relevant state-of-the-art similar embedding techniques. Superior results have been demonstrated in a number of experiments using several benchmark datasets.
SAR and Temperature Distributions in Canonical Head Models Exposed to Near- and Far-Field Electromagnetic Radiation at Different Frequencies

This article presents numerical computations of the specific absorption rate (SAR) distribution and temperature elevation in a canonical model of the human head—homogeneous spherical models exposed to near-field dipoles and far-field plane waves at 400 MHz and 900 MHz. Two homogeneous spheres filled with average brain equivalent materials are investigated: 18 cm approximating an adult head and 10 cm for child-head sizes. The distribution of SAR and temperature elevation computed for the spherical models are analyzed and compared. The computed SAR and temperature distributions inside the head models are very different for the near-field dipole and far-field plane wave. The highest SAR in both models occurred near the surface, directly beneath the feed point of the dipole. The decrease in SAR was faster at 900 MHz than at 400 MHz for the spherical head in the near field. In contrast, the maximum SAR shifted to inside the spheres for far-field plane waves, and was characterized by resonant oscillations, in both cases. The results indicated that 400 and 900 MHz RF energy from near-field 1/4 λ dipole antennas can penetrate about 100 and 80%, respectively, deeper into the smaller head model. In the homogeneous spherical head models, the induced temperature patterns were correlated closely with SAR distributions. However, the distribution and location of maximum temperature rise was different from that of SAR. The results suggest that 400 and 900 MHz RF fields from near-field 1/4λ dipole antennas could produce temperature elevations inside the smaller head model—at greater distances—about 70% deeper than the larger model.
Self-Expanding Metallic Stents for Palliation of Esophageal Cancer: A Single Center Experience From Saudi Arabia

Background: Self-expanding metallic stents (SEMSs) are increasingly used as a non-surgical alternative for the palliation of advanced esophageal cancer (EC). However, there is a scarcity of real-life experience with the use of these stents exclusively in EC. The aim of this study is to evaluate the efficacy of SEMS in inoperable ECs in the western region of Saudi Arabia. Methods: A retrospective review of SEMS placed in a tertiary referral hospital for histologically proven inoperable EC from 2016 to 2019. Demographics data, procedure success, complication, re-intervention, and mortality were analyzed. Results: Forty-eight SEMS placed in 35 patients for palliation of dysphagia. The median age of patients was 68 years (range 31-95). 69% (24) patients have a lower third of EC and the rest have a middle third. SEMSs were placed successfully in all cases with symptomatic improvement. No major stent-related complication was seen. 28% (13) patients required re-intervention with additional SEMS placement, nine of which were for tissue in growth and four for distal migration. Median survival was 114 days (range 30-498). Most of the complications seen in fully covered SEMS compared to the partially covered 50% (8/16) vs 17% (5/30), respectively, p = 0.04. Chemo and/or radiotherapy were given to 51% (18) of the patients without any significant benefit on survival (p = 0.79) or re-intervention rate (p = 0.47) compared to those who did not. Conclusion: SEMS is effective in palliating dysphagia in inoperable EC without major complications. Rates of tumors in growth and migration were comparable to other studies. SEMS provides long-term palliation.
Influence of Human Disposition on Change Implementation Communication : A Study Selected Food and Beverage Companies in Nigeria

Change implementation communication issues was investigated from human disposition perspectives during change implementation to deepen insight on drivers of success. Cross-sessional survey research design was adopted. Three hundred and ninety-two respondents were obtained from selected Food and Beverage companies in Lagos State. The respondent employees were the unit of analysis and a questionnaire was adopted with validity and reliability established. An econometric model was developed and the assumption tested. The findings revealed that employee commitment, attitude, and trust are drivers in communicating change initiative and success.
Photo-excitation in conjugated polymers

Conjugated polymers such as polyacetylene form a group of model semiconductors in which the 'one-dimensional' character of the polymer strongly modifies the behaviour of charges added to the chains from that usually observed in three-dimensionally bonded semiconductors. First, the polymer chain can undergo local reorganisation of the pi -electron bonding in the vicinity of a charge added to it. This has the effect of localising the charge in a state that can be described as a soliton for the particular case of trans-polyacetylene, and more generally as a polaron. Secondly, the motion of charged excitations is highly anisotropic, with strong confinement to the chain through the 'polaronic' structural relaxation of the chain. This anisotropy strongly affects charge transport and charge separation following photo-excitation. The authors review some of the recent work in this area and present polarisation-dependent measurements of photoluminescence (PL) and photo-induced absorption (PA) on highly oriented films of polyacetylene and poly(phenylenevinylene). They find that charge separation, detected through PA from photogenerated solitons or bipolarons, is the result of inter-chain electron transfer, whereas intra-chain excitation leads to charge confinement, and decay by PL (for poly(phenylenevinylene)) and by non-radiative channels. They find furthermore that these non-radiative channels become more efficient as the length of the conjugated polymer chain increases, and consider that this occurs through rapid motion of the excited state to recombination centres. They have identified both monomolecular and bimolecular kinetics for these processes.
COMPONENTS OF ARTIFACTUAL VARIANCE IN META‐ANALYTIC RESEARCH

Except for a few rough estimates, the literature contains no precise data on the relative size of each correctable artifact in a meta-analysis. The purpose of the present study was to determine these proportions and see if artifacts were related to various sample and subpopulation parameters. The study confirmed the notion that sampling error accounts for the bulk of the total artifactual variance (i.e., more than 90% for small or medium samples and more than 70% for large samples, e.g., N = 500). Nevertheless, variation in the percentages of each artifact was found to be primarily a function of sample size and mean correlation. Total artifactual variance was found to be a function of subpopulation correlation differences and sample size. Practical implications of the results are presented.
Radiation hydrodynamical wind revisited: Nonrelativistic regime

We re-examine the radiatively-driven spherical wind under the diffusion and local thermodynamic equilibrium (LTE) approximations, while focusing our attention on the topological nature of critical points. We ﬁrst consider the nonrelativistic case, where there is no radiation drag and advection luminosity. We ﬁnd that under the diffusion approximation almost all critical points (loci) are of the nodal type, which is higher order singular points, which makes the solutions stiff. On the other hand, under the LTE approximation, where the diffusive terms do not exist in the source terms, the critical points are of the saddle type, and transonic solutions are not stiff. Although the loci of critical points are quite similar for both approximations in the nonrelativistic regime, the types of critical points are found to be quite different.
Search for X-ray line emission from A0620-00

Measurements of the X-ray spectrum (1.85--7 keV) of A0620--00 obtained on 1975 October 17 and 1976 January 1--9 with the graphite crystal spectrometer on OSO-8 show a smooth continuum with an absence of emission lines. Upper limits are given for line emission from Si and S ions and are used to establish that the source is not optically thin. The results support a dense plasma model. (AIP)
Excitonic Bloch equations for a two-dimensional system of interacting excitons

We derive the effective Bose Hamiltonian for a system of interacting excitons applying the Usui transformation. The fermionic nonlinearities are consistently included, leading to a density dependent correction to the kinetic Hamiltonian and to a saturation of the exciton oscillator strength. The exciton-exciton interaction potentials due to the Coulomb interaction are calculated, accounting for the spin dependence. Starting from the effective Hamiltonian, we obtain the excitonic Bloch equations. As a first application, we study the problem of excitonic Rabi oscillations in quantum wells.
