Spectrophotometric determination of trace Arsenic (III) ion based on complex formation with gallocyanine

In this study, a simple, selective and sensitive method, for spectrophotometric determination of As(III) with gallocyanine as the sensitive reagent was developed. The wavelength of an analytical measurement, for the determination of As (III), using gallocyanine was at 630nm with an optimum response at pH 2. The RSD for the reproducibility of 100 ppm As(III) was 2.3%. The LOD was 0.04 ppm with linear dynamic range in As(III) concentration of 0.2 - 1.5 ppm. The developed method has been validated against Atomic AbsorptionSpectrophotometry (AAS). The interference study of several metal ions was carried out andit revealed that that Mn (II) ion was interfered the most

MONITORING SEASONAL VARIATION IN GROUND WATER QUALITY AND EVALUATION OF ITS SUITABILITY FOR IRRIGATION IN THE NIMRUD AREA SOUTH –EAST OF MOSUL –IRAQ

Sixteen water wells have been chosen in different locations within Nimrud district, to study the variation of ground water quality during the dry and the wet season. Analysis including salinity, pH, temperature, total hardness, major cations and anions were performed. Ground water salinity (EC) has significant variation and ranged from (0.81 to 5.82) and (0.88 to 5.77) ds m-1 in dry and wet seasons respectively. About 75% of water samples have a higher EC in the wet season compared with the dry season. All samples are very hard water class. Half of the wells have higher calcium and chloride concentration in the wet season than in the dry season. Two third of samples have higher Magnesium in the dry season than the wet season. Around 87% of wells have higher sodium and potassium in the wet season than dry season. About three quarters of wells have a higher sulphate in the wet season in compared with the dry season. About 80 % of samples have a higher nitrate concentration in the dry season compared to the wet season. Water quality for irrigation has been evaluated using several parameters. All samples fall into three category groups, C4S1, C4S2 and C3S1 according to the US salinity diagram

PSYCHIATRIC MANIFESTATION OF PATIENTS WITH BRONCHIAL ASTHMA IN MOSUL, IRAQ

Aims and methods: To identify risk factors and psychiatric morbidity in bronchial Asthma. Patients who consented to participate in the study, were checked for bronchial asthma. They were interviewed and their sociodemographic data were recorded, the hospital anxiety and depression was administered. Results were inputted in a computer programme and software statistical programme Minitab version 14.1 was utilised to analyse these data. Results: It showed statistically significant correlation between age, duration of asthma and HAD score. Implications: Psychiatric morbidity is a neglected area in the management and care of physical illnesses, especially, bronchial asthma, where patients may get very worried and scared during acute attacks when they feel that they may suffocate. Assessing and managing the psychiatric morbidity of such patients will be reflected on the outcome of the illness and improve the quality of life of such patients

Application of mcdm approach to evaluate the critical success factors of total quality management in the hospitality industry

Although many studies have focused on significant role of total quality management (TQM) in literature, little attention has been paid to using the fuzzy multiple criteria decision making (FMCDM) for analysis TQM factors especially in the context of hospitality. The purpose of this study is to identify, prioritize and evaluate the TQM critical success factors (CSFs) in hospitality industry by integrating the theory of fuzzy sets, quantitative and qualitative approaches. Primary criteria to evaluate TQM CSFs are achieved by the literature survey, and the Fuzzy Delphi Method (FDM) has been used by experts for evaluating of soft and hard TQM CSFs. In the following step, we employed the Fuzzy Analytic Hierarchy Process (FAHP) to find the weights of criteria. The results of this study indicated that, internal and external cooperation had the first rank among other CSFs in hospitality industry. In addition, the second and third rank in soft aspect includes customer focus and leadership respectively. The findings of this study shown guidance to practitioners and managers of quality to implement of TQM in their organizations, effectively by using the suggested set of identified TQM CSFs

Background A global epidemic of obesity has been documented, particularly among African countries. While central obesity and overweight have been reported for many countries, very limited information exists about the prevalence of these health problems in Sudan, and these data are nonexistent for Eastern Sudan. The present study aimed to determine the prevalence of obesity and central obesity, as well as the factors associated with both, among adults in Gadarif, Eastern Sudan. Methods A cross-sectional study was conducted in Gadarif, Eastern Sudan, during the period of January through May 2018. Sociodemographic and health characteristics data were collected through a questionnaire. Body mass index (BMI) and waist circumference (WC) were measured using the standard methods. Both descriptive and inferential statics were applied to analyze the data. Results A total of 594 adults participated in the study; 70.4% of them were female. The mean (standard deviation) age was 44.98 (16.64) years. Of the 594 enrolled participants, 33.7%, 7.4%, 26.8%, and 32.2% were normal weight, underweight, overweight, and obese, respectively. The prevalence of central obesity was (67.8%). Approximately, one-third of the participants (29.29%) were obese and had central obesity. In the multinomial regression, being married was the main risk factor associated with overweight, and older age, female sex, being married and hypertension were significantly associated with obesity. In the binary regression, the main risk factors associated with central obesity were female sex and being married. Conclusion The prevalence rates of both obesity and central obesity among the study participants were high. Older age and hypertension were only associated with obesity. Obesity and central obesity were significantly associated with female sex and being married. This study provided valuable baseline information to develop appropriate strategies for the prevention and control of obesity in Eastern Sudan
