A Study of Female Students Perceptions of the Barriers to Participate in Physical and Sports Activities at Al-Hussein Bin Talal University

The study aimed to examine the perceived barriers to participate in physical and sports activities among female university students as well as the potential differences of their perceptions of the barriers based on their academic discipline, academic year, and Grade Point Average (GPA) level. The participants in this study were 221 female students at Al-Hussein Bin Talal University. All the participants were undergraduate students. The study took place in the second semester of 2015/2016 academic year. Survey research approach was selected to guide the investigation. A questionnaire instrument, with five-point likert scale, was developed by the researchers as a data collection tool. The questionnaire instrument consisted from four parts that included:  social and religious barriers; university related barriers; academic barriers; and psychological barriers. The results indicated that the level of perceived barriers to participate in physical and sports activities was moderate. In addition, the results indicated that there were significant differences (α =.05) between the students’ means of perceptions of some types of barriers to participate in physical and sports activities based on their academic discipline and academic year.

Effect of Antibiotics on the Pathogenic Bacteria (K. pneumonia and P. aeruginosa) Isolated Around the Dental Implant Area

In this study, the bacterial isolates (36) were obtained from total 52 samples were taken Twenty K. pneumonia and sixteen P. aeruginosa isolates were found in the dental implant region of individuals of varying ages and sexes who visited a single dental clinic. It was determined what kind of bacteria had been identified by culture, microscopic characteristics and biochemical tests. The resistance and sensitivity of isolates to eight antibiotics (Ceftazidime CAZ, Amikacin Ak, Ciprofloxacin CIP, Chloramphenicol C, Meropenem MEM, Gentamycin GN, Imipenem IMI, Amoxicillin Clavulanate AMC) were studied, with depending on the diameter of the inhibition on Muller-Hinton Agar medium and its comparison with the standard ratios in the Clinical and Laboratory Standards Institute (CLSI, 2018). The results showed that the highest percentage of resistance K. pneumonia bacteria was to Ceftazidime and Amoxicillin Clavulanate, which reached (100% ,90%), respectively. It was followed by Gentamycin (77%), Ciprofloxacin (67%) and Amikacin was (40%). While the lowest percentage of resistance to the antibiotics (Imipenem, and Meropenem) were (25%) and Chloramphenicol was (20%). As for bacteria. aeruginosa the highest percentage of resistance was to the antibiotic Ceftazidime (93%), followed by the antibiotic Amikacin by (71%), Chloramphenicol (58%), Gentamycin (47%), Meropenem (42%), then the antibiotic Imipenem (40%) While the lower percentage of resistance to the antibiotic Amoxicillin Clavulanic (39%) and Ciprofloxacin (20%). This review provides a complex effect of antibiotics to understand of mechanism and effects of the antibiotic is the base for the new approaches in clinical treatments by which can effectively fight the groups of the resistant pathogens, in patients who are at high risk specially when undergo dental procedures

Anti-Disturbance Compensation-Based Nonlinear Control for a Class of MIMO Uncertain Nonlinear Systems

Multi-Inputs-Multi-Outputs (MIMO) systems are recognized mainly in industrial applications with both input and state couplings, and uncertainties. The essential principle to deal with such difficulties is to eliminate the input couplings, then estimate the remaining issues in real-time, followed by an elimination process from the input channels. These difficulties are resolved in this research paper, where a decentralized control scheme is suggested using an Improved Active Disturbance Rejection Control (IADRC) configuration. A theoretical analysis using a state-space eigenvalue test followed by numerical simulations on a general uncertain nonlinear highly coupled MIMO system validated the effectiveness of the proposed control scheme in controlling such MIMO systems. Time-domain comparisons with the Conventional Active Disturbance Rejection Control (CADRC)-based decentralizing control scheme are also included

DNA Polymorphism of Gaucher Disease in Iraqi Patients

Gaucher disease is the autosomally recessively inherited deficiency of the lysosomal enzyme glucocerebrosidase. Increasing storage of glucocerebrosides leads to a multisystem disease, the prevalence of which is about 1 : 40,000 in central Europe and up to 1 : 2,000 in some other countries (e. g. Israel). The acute and chronic neuronopathic forms of the disease (formerly defined as Gaucher types 2 and 3) account for only 5 to 10% of all Gaucher patients in Central Europe and Germany and are thus less frequent than the nonneuronopathic disease (formerly defined as Gaucher type 1). Gaucher's disease is usually associated with splenoand hepatomegaly, fatigue, skeletal complications, and several corresponding hematological and laboratory abnormalities. In 5 to 10% of the patients there are also central nervous symptoms such as myoclonic seizures, oculomotoric apraxia and a slight mental retardation. Recent epidemiological data indicate that only 10 to 20% of all Gaucher patients are correctly diagnosed (and treated) in Germany. The diagnosis today can be done in all patients by noninvasive methods, i. e. determination of the glucocerebrosidase activity in peripheral leukocytes and of the genetic defect, in this research the PCR technique was used to analyze the mutation in glucocerebrosidases gene (G ---C). Key words: Gaucher disease (GD), lysosomal storage disorder (LSD),lysosomal enzyme glucocerebrosidase, PCR, Mutation

Exploring the Nexus between Profitability, Dividend Policy and Share Prices in Kuwaiti Insurance Companies

The purpose of this study is to investigate the impact of dividend policy and profitability ratios on the share prices of insurance companies listed on Kuwait Stock Exchange (KSE) between 2014 and 2022. The study's findings demonstrated that 42.4% of share prices could be explained by factors related to profitability and dividend policy. Earnings per share (EPS) was the only variable that demonstrated a significant direct relationship with share prices when the individual effects of each variable were examined. While dividend payout ratio (DPR) exhibited a negative correlation with stock prices, it was not statistically significant. Other characteristics that were considered included dividend yield (DY) and interest rate (IR), both of which showed significant inverse relations. This study concludes that investors in Kuwait Stock Exchange (KSE) shares of the insurance sector favor unpredictable future capital gains over more assured dividends
