Risks, Vulnerability and Primary Education in Sudan
Hisham Mohamed HASSAN ALI
Revista Romaneasca pentru Educatie Multidimensionala , 2012,
Abstract: This paper has dealt with risks and vulnerability facing primary education in Sudan at micro and macro levels. Sudan is exerting great efforts to achieve a good progress in primary education system as indicated by GER, however, the system is still facing weakness in different ways. The pupils in Sudan suffer from different kinds of risks and vulnerable that our communities have failed to handle; at home (parents, adults, etc.), at school (teachers), and at community level (laws, policies, etc.). The paper has also shown that for children, the experience of risk, vulnerability at micro and macro levels is shaped by four broad characteristics. Multidimensionality, changes over the course of pupils, relational nature, and voicelessness.
Prognostic Value of Retinal Nerve Fiber Layer and Ganglion Cell Complex after Optic Chiasmal Decompression  [PDF]
Shaymaa Hassan Salah, Ahmed Mohamed Ali
Open Journal of Modern Neurosurgery (OJMN) , 2019, DOI: 10.4236/ojmn.2019.91004
Abstract: This paper is an attempt to ascertain the role of the optical coherence tomography by measuring the retinal nerve fiber layer thickness and ganglion cell complex area to predict postoperative visual outcome after chiasmal decompression. 16 eyes scheduled for chiasmal decompression surgery were assessed before and 3 months after surgery with standard automated perimetry and OCT (optical coherence tomography). Preoperative RNFL (retinal nerve fibre layer) thickness and GCC (ganglion cell complex) area were compared with 20 normal control eyes. 13 cases were operated by microscopic assisted endoscopic endonasal transsphenoidal approach; the remaining 3 cases were operated transcranially. Spearman’s correlation analysis was used to evaluate the relationship between preoperative RNFL thickness, GCC area, postoperative mean deviation and temporal visual field sensitivity (1/Lambert). Preoperative measurements of RNFL thickness and all GCC area were significantly reduced in the patients compared with normal control. 3 months postoperative evaluation showed improvement of the visual field, but reduction in global and sectorial RNFL thickness except for nasal sector. Moreover, absolute postoperative (not pre-post change) visual field parameters were significantly correlated to preoperative RNFL (P = 0.00399 for mean deviation, P = 0.0023 for temporal sensitivity), GCC thickness (P = 0.00736 for mean deviation, P = 0.0469 for temporal sensitivity), with FLV (focal loss value) (P = 0.0012 for mean deviation, P = 0.0021 for temporal sensitivity) showed a higher correlation. Reduced RNFL thickness mainly, and GCC area minimally, were associated with the worst visual field outcome. FLV is a new prognostic value.
Quality Evaluation of Some Fresh and Imported Frozen Seafood
Fatma Hassan Mohamed Ali
Advance Journal of Food Science and Technology , 2011,
Abstract: This work was done to evaluate the quality parameters of fresh and imported frozen seafood (fillets and shrimp). A total of 120 seafood samples, fillets and shrimp (fresh and imported frozen) 30 each, collected from fish markets at Giza Governorate were sensory, bacteriological, chemical investigated. Panelists rejected 5.0 (16.6%) and 0.0 (0.0%) of fresh fillets and shrimp samples, while the number raised up to 12.0 (40.0%) and 15.0 (50.0%) of frozen fillets and shrimp samples respectively. Fresh seafood had a significant lower (p<0.05) pH values in compared to frozen products. There were observed significant difference (p<0.05) in the TBA and TVB-N values between the fresh and frozen seafood samples. All fresh and frozen seafood samples were judge as safe food from microbiological point of view. The total proteolytic, lipolytic, psychrotrophic and pseudomonas/aeromonas counts for all examined seafood samples were lie within the standard permissible limits. L. monocytogenes could not be detected from fresh or frozen fillets. Few freqyency of L. monocytogenes found in fresh and imported frozen shrimp. As well as V. parahaemolyticus and Y. enterocolitica were recovered from examined fresh and frozen seafood samples. The public health significance of the isolated organisms was also discussed. The quality of fresh fillets and shrimp were better than that of imported frozen one.

Amaly Mohamed Hassan, Azza Mahmoud Mazrouaa, Mona Ali Youssif, Rabab Mohamed Abou Shahba, Maha Ali Youssif
International Journal of Organic Chemistry (IJOC) , 2013, DOI: 10.4236/ijoc.2013.31008
Abstract: The wax gel grease (S0) was prepared from a mixture of 2.3:1 base oil blend (base oil grade 260/290, transformer oil), and microcrystalline wax in the presence of 0.1% - 2% of polyoxyethylene sorption nano-palmitate as antioxidant and 2,2 methylene bis (4-methyle-6-tertiary butyl phenol) as anticorrosion. It was found that the prepared Wax gel grease has inconvenient physico-chemical and dielectric properties, so in order to improve its physico-chemical properties (viscosity, penetration, dropping point and water resistance) and dielectric Properties (dielectric constant, dielectric loss and volume resistivity), Butyl rubber, isoprene rubber and bitumen were added separately as thickening agents to the prepared wax gel in certain proportion at certain frequency range 1 - 1000 KHz at 35°C. The best dielectric properties were achieved by adding butyl rubber to the prepared wax gel.

Hassan H. M. Zaky, Dina M. Armanious, Mohamed Ali Hussein
Open Journal of Obstetrics and Gynecology (OJOG) , 2015, DOI: 10.4236/ojog.2015.510078
Abstract: Objectives: This study empirically assesses the impact of the changes in women’s characteristics, empowerment, availability and quality of health services on woman’s decision to use antenatal care (ANC) and the frequency of that use during the period 2000-2008. Study Design: The study is a cross-sectional analytical study using 2000 and 2008 Egypt Demographic and Health Surveys. Methods: The assessment of the studied impact is conducted using the Zero-inflated Negative Binomial Regression. In addition, Factor Analysis technique is used to construct some of the explanatory variables such as women’s empowerment, the availability and quality of health services indicators. Results: Utilization of antenatal health care services is greatly improved from 2000 to 2008. Availability of health services is one of the main determinants that affect the number of antenatal care visits in 2008. Wealth index and quality of health services play an important role in raising the level of antenatal care utilization in 2000 and 2008. However, the impact of the terminated pregnancy on receiving ANC increased over time. Conclusions: Further research of the determinants of antenatal health care utilization is needed, using more updated measures of women’s empowerment, availability and quality of health services. In order to improve the provision of antenatal health care services, it is important to understand barriers to antenatal health care utilization. Therefore, it is advisable to collect information from women about the reasons for not receiving antenatal care.
Determinants of Antenatal Health Care Utilization in Egypt (2000-2014) Using Binary and Count Outcomes  [PDF]
Hassan H. M. Zaky, Dina M. Armanious, Mohamed Ali Hussein
Health (Health) , 2019, DOI: 10.4236/health.2019.111004
Abstract: Aim: This study seeks to investigate the factors determining the utilization of antenatal care services, the frequency of that use, and the timing of receiving antenatal care among Egyptian women utilizing a national representative data from Egypt Demographic and Health Surveys (EDHS) in 2000 and 2014. Methods: The paper estimates the logistic regression model, zero-inflated negative binomial model (ZINB), and negative binomial regression model (NB) to identify the most important determinants of antenatal health care utilization. Results: The findings indicate that the period 2000-2014 has experienced a significant increase in the use of antenatal health care services. The use of the public sector antenatal care services relative to that of the private sector has been decreasing over time. Moreover, wealth index, women’s education and quality of health services play significant roles in increasing accessibility of antenatal health care services. On the other hand, women’s empowerment has shown a positive effect in 2000 only. Conclusion: The study highlights the most vulnerable groups that are less likely to have access to antenatal health care services, mainly women who are less educated, poor and living in rural areas especially Upper Egypt. This certainly requires a more targeted health strategy with an equity lens.
ESCAPING RURAL IMPOVERISHMENT TO URBAN POVERTY, DELTA TOKER MIGRANT FARMERS SQUAT PORT SUDAN TOWN, EASTERN SUDAN
Samir Mohamed Ali Hassan Alredaisy
Academic Research International , 2012,
Abstract: This paper is based on data provided by fieldwork conducted in the squatter area of Walia’ in north Port Sudan town during March 2010. The paper objects to investigate urban poverty by using demographic, socioeconomic and nutritional characteristics of the migrants to argue on causes of rural impoverishment. The main findings revealed that 30% of the respondents were born in Port Sudan town, 15% outside eastern Sudan while 55% of them were born inside Delta Toker agricultural scheme. Failure of agricultural production there has driven 65% of them to move to Port Sudan town while drought as a pushing factor constitutes 30%. Average family size is 8.16 persons, mean age is 22.5 years and younger age groups of 5-9, 15-19 and 20-24 constitute the majority of the population. Average monthly income is 120 USD or 4 USD per day.More than of the population are far below the mean monthly income. Percentage of students in basic education is 34.6% while for those in secondary education it is 31.9%. Average household daily intake of cereals; bread; meat; sugar; milk; vegetables and vegetable oils are 3420 grams; 158.4 grams; 270 grams; 444.5 grams; 520.4 grams; 420 grams and 209.2 respectively. The per caput per day intake of these basic food items are respectively 419.1 grams for cereals; 19.4grams for bread; 33.0 grams for meat; 54.5 grams for sugar; 63.8 grams for milk; 51.5 grams for vegetables and for vegetable oil amounts to 25.6 grams. The per caput per day intake of nutrients is 56.8 grams of protein; 379.8 grams of carbohydrates; 50.3 grams of fats; 44.8 gramsof Iron; 15.8 mg of vitamin A and 13.9 mg of vitamin C. These values confirm failure to meet international standards concerning food intake, as well as the per capita consumption of nutrients per day for population in Africa. People reduce number of meals, substitute expensive food types by cheaper items, use alternative food types, transfer food between households and borrow money to cope with food unaffordability. The author proposes rural – urban territory development model to contribute into the alleviation of rural impoverishment and consequently urban poverty.

Case Reports in Clinical Medicine (CRCM) , 2015, DOI: 10.4236/crcm.2015.48054
Abstract: Fanconi’s anemia (FA) alson called Fanconi Pancytopenia is a rare, potentially life-threatening failure of haemopoiesis characterized by aplastic anemia that is associated with a variety of congenital abnormalities (Cafe-au-lait spots, abnormalities of fingers, hyperpigmentation of the skin, short stature, microcephaly, deformities of the ear, hypogenitalism, renal anomalies, etc.) and a high risk of developing of malignancy and chromosomal instability. FA is the first described in 1927 by Guido Funconi reported 3 brothers with pancytopenia and physical anomalies. The diagnosis is based on morphological abnormalities, hematologic abnormalities and genetic tests. The present case report describes a 10 years old Somali boy was diagnosed with a Fanconi anemia after recurrent blood transfusion. Though aplastic anaemia in children is an important haematological disorder, there is no study having been undertaken in Somalia and this is the first reported by the patient with Fanconi’s anemia in Somalia. We report this case to create awareness among clinicians the presence of this disease and have a consideration when it comes differentiatal diagnosis of recurrent blood transfusion patients with pancytopenia because it’s a rare genetic disease in Mogadishu and around the world.

Abstract:

Hypoxia, due to impaired cerebral blood flow, has hazardous effects on brain structure and function. To minimize as much as possible the neurological consequences from hypoxic-ischemic (HI) brain injury, neuro-protective strategies are urgently required. Vitamin E has been shown to have protective effects against cerebral ischemia, possibly due to its anti-oxidant effects. Thirty albino rats, of both sexes, were obtained from the animal house at King Khalid University Hospital, King Saud University. They were divided into three groups; each included 10 animals: Group A was considered as a control one, animals of Group B were subjected to a permanent link to the carotid arteries on both sides and animals of Group C underwent permanent link to carotid arteries on both sides and concomitantly were given Vitamin E as an anti-oxidant. Animals of Group C were injected by Vitamin E (equivalent to 15 mg/day), into the peritoneal cavity as a single dose for a week and after the prescribed period the mice were sacrificed under deep anesthesia and their brains were extracted and prepared for an electron microscopic study of brain tissue. Specimens from animals of Group B showed a large number of neurons that had been deteriorated. Mitochondria were the most affected organelles. There were a large number of dark cells which probably resulted from shrunken nerve cells and exhibited opaque nuclei. The number of affected nerve cells was much lower in brain tissues from animals of the Group C which revealed absence of dark cells. The study did not disclose any similar changes in brain tissues of the control group animals. Our results suggested that treatment with Vitamin E after hypoxia-ischemia
