Epidemiology of underweight and overweight-obesity among term pregnant Sudanese women
Duria A Rayis, Ameer O Abbaker, Yasir Salih, Tayseer E Diab, Ishag Adam
BMC Research Notes , 2010, DOI: 10.1186/1756-0500-3-327
Abstract: Out of 1690 term pregnant women, 628 (37.1%) were primigravidae, 926 (54.8%) had ≥ secondary educational level (minimum of 8 years) and 1445 (85.5%) were housewives. The mean (SD) of the age and parity were 27.2 (6.3) years and 2.0 (2.1) respectively. Out of these 1690 women, 94(5.5%) were underweight (BMI of ≤ 19.9 Kg/m2), 603 (35.6%) were overweight (BMI of 25 - 29.9 Kg/m2) and 328 (19.4%) were obese (BMI of ≥ 30 Kg/m2).In multivariate analyses, obesity was positively associated with age (OR = 1.2, 95% CI = 1.0-1.1; P< 0.001), and with women's education (OR = 1.8, 95% CI = 1.2-2.7; P = 0.001). Obesity was positively associated with parity in univariate analyses only (OR = 1.1, 95% CI = 1.0-1.2; P = 0.02)The high prevalence of obesity in these pregnant women represents a competing public health problem in Sudan. More research is needed.Many developing countries are currently affected by high rates of overweight that in some cases surpass underweight as a public health nutritional problem. Recent reports showed that, in many developing countries e.g. Bangladesh, Nepal, and India, the prevalence of overweight-obesity in women of reproductive age has risen steadily in the last two decades [1]. In the case of Africa, recent analyses of national data on body mass index (BMI) from women showed that, the prevalence of overweight-obesity exceeded that of underweight [2].Increasing BMI is associated with increased incidence of pre-eclampsia, gestational hypertension, macrosomia, induction of labor and caesarean delivery [3]. We have recently observed that, both type of malnutrition (underweight and overweight-obesity) were associated with poor pregnancy outcomes in pregnant Sudanese women [4,5]. Generally few data are available concerning epidemiology of obesity during pregnancy in Sub-Saharan Africa and none available for Sudan the largest African country with 40 million populations. Sudan has traditionally been known as to have the highest rates of poverty -and may be und
Le pétrole en Inde Oil in India
Diab E.,Raimbault C.
Oil & Gas Science and Technology , 2006, DOI: 10.2516/ogst:1995049
Abstract: L'Inde est un pays riche en ressources énergétiques. En ce qui concerne le pétrole, les réserves prouvées sont déjà abondantes, mais certains pensent qu'il reste un potentiel très important à découvrir, le pays étant un des moins explorés du monde. L'ouverture récente des industries de l'énergie aux capitaux privés et étrangers devrait accélérer le développement de l'exploration, du raffinage et de la pétrochimie. Mais, bien que de nombreux projets aient été approuvés par le gouvernement, la réalisation ne suit pas dans tous les cas, en raison de conditions qui ne sont pas toujours jugées attrayantes par les investisseurs potentiels. Malgré tout, certains pensent que l'Inde sera une puissance égale sinon supérieure à la Chine et qu'elle soutient déjà la comparaison avec les dragons du Sud-Est asiatique. India is a country that is rich in energy resources. Concerning oil, proven reserves are already abundant, but there are some who think that a very large potential remains to be discovered, since the country is one of the least throughly explored in the world. The recent opening up of energy industries to private and foreign capital should speed up the development of exploration, refining and petrochemicals. However, even if numerous projects were to be approved by the Government, actually carrying them out does not always ensue because of conditions that are not always judged to be attractive by potential investors. Despite all this, there are some who think that India will be a power equal to if not greater than China and one that is already upholding the comparison with the Southeast Asian dragons.

Mohammad Tayseer Kayed AlTamimi
Natural Science (NS) , 2010, DOI: 10.4236/ns.2010.27099
Abstract: When I put Kepler’s first law under peer review, I note: 1) There is an isolation cordon between daytime and night = 13.88 m; 2) Earth’s Rotation Axis loses its tendency to its mother (Polaris now) in winter; 3) Celestial’s equator doesn’t parallel Earth’s equator; 4) Ice sheet in Antarc tica equals ice sheet on arctic. But we find the field observation data contrary to that.
The Effect of Designing a Blended Learning Environment on Achievement and Deep Learning of Graduate Students at the Arabian Gulf University  [PDF]
Ahmed Nouby, Tayseer Alkhazali
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.510022
Abstract:
The present study aimed to investigate the effect of designing a blended learning environment on achievement and deep learning of the Arabian Gulf university students in a design and presentation of instructional materials’ graduate course. A blended learning environment was designed to provide opportunity for integrating the learning management system “moodle” with face-to-face classroom interaction. To investigate research questions, a quasi experimental design was used. The study sample consisted of 19 male and female graduate students pursuing their studies at the “Distance Teaching and Training Program” in the College of Graduate Studies during the first semester of the academic year 2015/2016. To explore the extent to which students learnt the course content, an achievement test was used. A deep learning scale was also used to investigate the depth of learning acquired by students who studied the course content through the blended learning environment. Results of the study showed that students’ scores on the post application of the achievement test were improved. No statistically significant differences were found between students’ mean scores in the pre and post applications of the depth of learning scale. However, mean of students’ scores in the post application of the depth of learning scale (65.3750) was noticed to be slightly higher than that of the pre application (63.1250). Such higher mean might represent slight improvement in the depth of learning among students.

Health (Health) , 2011, DOI: 10.4236/health.2011.37073
Abstract: The description of various methods for ethnicity classification can be found in the literature, though their reliability still remains unclear. We examined inter-observer agreement in defining the ethnic identification of patients in a bi-ethnic population (Arab-Jewish) in northern Israel, using place of birth and residence in addition to given and family names. Data about 1006 consecutive patients with acute ischemic stroke were gathered from our stroke registry. The data were analyzed by four independent observers (authors MH, TD, HH, GT) aiming to assign patients either as Arabs or Jews. Agreement between all four observers was excellent, as assessed by Fleiss’ Kappa statistic (κ = 0.96). We conclude that the use of given and family names of patients, together with their place of birth and residence, achieved near-perfect inter-observer agreement and a highly reliable assignment of ethnicity in two large ethnic population groups–Arabs and Jews–in northern Israel.

Samir Abd Elghafar, Salaheldin M. Diab, Bassiouny M. Sallam, Moawad I. Dessouky, El-Sayed M. El-Rabaie, Fathi E. Abd El-Samie
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2014, DOI: 10.4236/ijcns.2014.71001
Abstract:

The sine transform can be used as a tool to conquer the problems of discrete multi-tone (DMT) systems to increase the bit rate. In the proposed discrete sine transform based discrete multi-tone (DST-DMT) system, we make use of the energy compaction property of the DST to reduce the channel effects on the transmitted signals. The mathematical model of the proposed DST system is presented in the paper. Simulation experiments have been carried out to test the effect of the proposed DST-DMT system. The results of these experiments show that the performance of the DST-DMT system is better than that of the traditional FFT-DMT system. The results also show that employing the proposed TEQ in the DST-DMT system can increase the bit rate by about 2.57 Mbps.

Communication in diabetes management: overcoming the challenges
P Diab
Journal of Endocrinology, Metabolism and Diabetes of South Africa , 2012,
Abstract: Medicine is both a science and an art; a delicate balancing act of scientific diagnostic reasoning and management on the one hand, and the development and nurturing of a relationship with another person, on the other. Patients seek a healthcare provider who can provide them with a service. They want someone who will provide explanations, answer their questions, and alleviate their fears. Patient adherence to chronic medication regimens is greatly improved if a bond of trust exists, to sustain a strong doctor-patient relationship.

Intestinal Bacterial Flora that Compete on the Haem Precursor Iron Fumarate in Iron Deficiency Anemia Cases
Selim, S. A. H.,Alfy, S. M. E.,Diab, A. M.,Abdel Aziz, M. H.
Malaysian Journal of Microbiology , 2012,
Abstract: Aims: The study focused on finding if there is any possible relation between the intestinal bacterial population quantitative and qualitative and the deficiency of the most important iron compounds as haem precursors. Methodology and Results: Blood complete picture and stool analyses were done to 750 volunteer cases whom were asked for these analyses by their physicians. Analyses proved that 560 cases representing 75.2 % were anemic as the RBC(s) based on counts of the total studied cases of less than 263 x 104 and the haemoglobin amount ranged between 7.2 and 11.3 g/dl, while the remainder 24.8 % of the volunteer sample was not anemic. A high male/female ratio ofanemic cases, 1:27 was also documented. Considering that all the studied stool samples should be completely free from any parasites or any other anemia-related diseases was a priority. Bacteriological analysis of stool samples of the anemic cases resulted in the detection of high counts of total viable bacteria, exceeded 42 x 109 cfu/g, while it was never more than 26 x 106 cfu/g and decreased to 4 x 106 cfu/g in many cases in this study. Identifying of the 361 bacterial isolates, were found to belong to 12 genera and 19 species, 6 of them; Pseudomonas putrefaciens, Micrococcus luteus, Erysipelothrix rhusiopathiae, Bacillus megaterium, Bacillus pumilus and Bacillus coagulans , were found and in high counts in the stool samples of only anemic cases. The ability of these isolates to compete for iron compounds such as ferrous fumarate alone or with glucose and phytate as activators or inhibitors to these abilities was investigated. Results proved 11 species out of the 19 identified species are capable to use and compete on ferrous fumarate as a haemprecursor. Sensitivity test for the representatives of the 19 species and 6 of the most commonly used antibiotics in the Egyptian pharmacy, using standard disc method, revealed variable susceptibilities of almost all of them to more than one of the studied antibiotics, except Corynebacterium equatium, which was found very resistant to two antibiotics; colistin sulfate and erythrocin. Conclusion, significance and impact of study: The study finally concluded the strong role of intestinal bacterial counts and types as competitors on the haem precursor iron-containing compounds like ferrous fumarate.
Validation of 226Ra and 228Ra Measurements in Water Samples Using Gamma Spectrometric Analysis  [PDF]

Journal of Water Resource and Protection (JWARP) , 2013, DOI: 10.4236/jwarp.2013.58A008
Abstract:

Radium isotopes can be analyzed by different analytical methods based on gamma spectrometric measurements or alpha spectrometry. An improved method was developed to determine radium isotopes from water using gamma spectrometry after radiochemical separation. The Radium was selectively extracted from acidified samples using co-precipitation procedure with iron hydroxide and followed by precipitation of radium as radium sulphate Ba(Ra)SO4. The precipitate Ba(Ra)SO4 was filtered through the Millipore filter paper, dried and weighed to calculate chemical yield. 226Ra and 228Ra activities were measured using low-background gamma spectrometry in water samples. Radium was pre-concentrated from environmental samples by co-precipitation with BaSO4. The amounts of 226Ra and 228Ra on the sample were obtained by gamma-ray spectrometry for the 351 keVγ-ray from 214Pb and for the 911 keV γ-ray from 228Ac, both in radioactive equilibrium with precursors, respectively. The accuracy, selectivity, traceability, applicability and Minimum Detectable Activity (MDA) of the technique were
