    In the current world, poverty and education are interconnected. Low level of education is the cause of poverty, as extreme forms of poverty do not allow many children to get a good education. This study investigates the risk factors that significantly increase the likelihood of pupils dropping out of school in Khartoum, Sudan. To accomplish the research, two factors are selected, namely absenteeism and low performance of pupils from poor, disadvantaged communities. A comprehensive interviewing is used to collect the necessary primary data along with the Multidimensional Poverty Index (MPI) data. The life of pupils is characterised by multi-dimensional poverty apace with illiteracy, displacement and large family size, parents' engagement in low paid jobs. The pupils presented multiple reasons (related to poverty) for their absenteeism and low performance. The results indicate that pupils are not clear with their future perspectives whether to drop out of the school or to continue their studies. The study concludes that poverty is the main reason for absenteeism and low performance that increases the likelihood of pupils dropping out of school

    This historical case study examines the rhetoric, action, and outcomes of educational policy reforms in Egypt during the first quarter-century of the presidency of Mohamed Hosni Mubarak. The findings are based on an extensive review of Egyptian government, international organization, and project documents as well as interviews with key stakeholders. The study focused on proposed and implemented changes in the organization and distribution of various governance and management functions across school/community, district/idarra, governorate/muddiriya, and national/central levels of the education system. During the period under review Egypt experienced movement though uneven toward increased decentralization, with calls for deconcentration of responsibility in 1981, Ministry of Education actions that restricted local decision-making authority in the 1990s, and some concerted efforts toward delegation and devolution of authority as well as responsibility after 2001. In terms of community participation, during this period there were calls for and actions toward implementing broader and deeper forms and degrees of involvement by parents, civil society, and businesses. We draw on the following concepts to analyze a develop an account of these developments: institutional framework, financial resources, system leaders' capacity and political will, civil society's leaders' capacity and political will, global dynamics, and the role of international organization

    Background: Hypomagnesaemia may have negative impact on glucose homeostasis and insulin sensitivity. This study was done to compare serum Mg levels in type 2 diabetic patients with non diabetic healthy control subjects and to assess the correlation between serum Mg levels and glycemic control in Egyptian patients.Methods: 60 type 2 diabetic patients attending the outpatient clinic of diabetes at Kasr Al Aini hospital faculty of medicine Cairo University and 30 healthy age matched control subjects were enrolled. Fasting blood sugar, fasting insulin, fasting lipids, Hb A1C and serum Mg were measured. Weight, height and blood pressure were recorded. BMI, IR (HOMA), were calculated. The data was analyzed and expressed in terms of mean ± SD. Pearson correlation was performed to establish the relationship between Mg and metabolic variables in type 2 diabetic patients.Results: serum Mg levels were significantly reduced in type 2 diabetic patients compared to the control group with mean ±SD (1.29 ± 0.31 mg/dl) versus (2.41 ± 0.13 mg/dl) with P value < 0.001. There were highly significantly negative correlations between serum Mg levels and HbA1c, fasting glucose and insulin resistance with (r = -0.969, -0.894, -0.653) respectively, P value < 0.001. The best cut off point of Mg was ≤ 2.0 mg/dl in differentiating cases from controls using ROC curve analysis.Conclusion: hypomagnesaemia is closely linked to type 2 diabetes mellitus and it is strongly correlated to glycemic control. We recommend to measure serum Mg in type 2 diabetes and patients who need supplementation should be considered.

    Cellular ultrastructure micrographs revealed striking changes resulting from the Barley Yellow Dwarf Virus (BYDV-PAV) infection in Electron microscopy. In the cytoplasm, the Gold nanoparticles (AuNPs) may bind with different cytoplasmic organelles and interfere with the treated site’s metabolic processes. The micrographs of the treated plant leave with AuNPs showing; Endosomes, amorphous bodies, slender filaments fibers, myelin bodies with a high concentration of virus particles, and Gold Nanoparticles distributed in a circulated shape in the cytoplasm with virus particles

    Photosynthesis is a crucial process for plants on earth that changes light energy to chemical energy. Virus infection can cause dramatic photosynthesis changes: respiration and the translocation of carbohydrates and other substances around the host plant. Chlorosis in virus-infected leaves like Barley Yellow Dwarf Virus (BYDV- PAV).infection can result from damage to chloroplasts resulting from inhibition of photosynthetic activity. Our present study combines TEM and chlorophyll-level content in the presence of Gold nanoparticles (AuNPS) to explore the repair mechanism for the yellowing leaf symptom development caused by infection with BYDV- PAV by illustrating TEM micrographs; showing fragmentized grana, deformation of the myelin like bodies (MLB), many vesicles; osmiophilic lipid granules/plastoglobulus, starch body, and plasmolysis in the chloroplast, distribution of AuNPs & VLPs near and inside the chloroplast.

    The Intervention of Gold Nanoparticles (AuNPs) Interactions Lead to the Disappearing of Virus Particles

    In the context of plant-pathogen interaction, the application of nanoparticle technology and efficient transportation of substances, such as systemic AuNPs to the specific coupling of AuNPs and virus, provide novel solutions for the treatment of plants against the virus. The included data proved that AuNPs provide an efficient means to control virus infection in a fashion way with reducing collateral damage. The AuNPs assure fatal damage to the VLPs with low concentration using different AuNPs sizes. Synergistic therapeutic effects could lead to virus resistance

    In our application of AuNPs on the leaf surface, we were pushing the Barley Yellow Dwarf Virus (BYDV-PAV) source and Gold nanoparticles (AuNPs) into the plant cell system up on the events of systemic plant defense response. In the infected host cell, the viral coat protein is the first obvious in the cytoplasm. When nanoparticles are applied on leaf surfaces, a large surface area relative to their volume happens. AuNPs solutions are more active and dispersed ooplasm. The correlation between Zeta potential value and Zeta sizer is inverse proportion. Filaments are visible in the nucleopores, the nuclear outline is distorted, and massive clumping of heterochromatin begins as declared. It was mostly found in or around regions of ribosome-associated filaments. Our present study combines TEM and nucleus content in the presence of AuNPS to explore the level of repair mechanism illustrating in TEM micrographs, showing Polyploidy nucleus and segregated chromatin. Multi membranous structure, imaging the AuNPs inside and around the nucleus and Pseudo crystal array is enveloped in an endoplasmic reticulum cisterna (ER)

    The application of AuNPs on the infected barley cultivar had great damage results on Barley Yellow Dwarf Virus (BYDV-PAV) particles in TEM. Observation of TEM images provided an insight into the transport of AuNPs through the plasmodesmata endoplasmic reticulum route, where they likely accumulated as the channels narrowed. The cytoplasmic parenchyma cell components do not have an intact peripheral location, but taking irregular shapes, internal movement between adjacent two cells seems to be the VLPs moved toward via plasmodesmata. TEM micrographs; showing different abnormalities in the cell wall due to viral infection. Application of AuNPs revealed sticky Integrated AuNPs inside the cell wall with low and high density. The mechanical transportation of the virus through the sieve elements with endosomes was observed. The mechanical transportation of virus particles through the cell wall with some vesicles, amorphous inclusions, and filamentous particles was proved through the sieve elements with filamentous strands
