Effects of Physical Exercise in Ameliorating Symptoms of Children with Autism in China: A Meta-Analysis
Lin Li-Xin, Liu Hua-xuan and Chow Bik-chu
Childhood autism is a developmental disorder characterized by difficulties with communication and behaviors. The benefit of physical exercise on behavioral and cognitive functions have been widely recognized. This article aims to explore the effects of exercise intervention on ameliorating symptoms of childhood autism with a meta-analytical approach. The results included five research papers comprising of a total of 282 research subjects aged 3~18-year-old. A random effect model was adopted to test the combined effect size. For children with moderate autism symptoms, the results were: heterogeneity test of Q=94.60, df=11, p<0.05, I2=83.4%, combined effect size of SMD = -1.36, 95% CI (-1.76, -1.12), and Z=6.45. For Children with severe autism symptoms, the results were: heterogeneity test of Q=1.57, df=3, p>0.05, I2=0.1%, combined effect size of SMD = -0.49, 95% CI (-0.5, -0.19), and Z=3.35. The results revealed an overall medium effect, supporting that exercise can significantly ameliorate the symptoms of severe autism in children, especially among those with moderate-level symptoms. However, the effect of exercise on severe autism was on a marginal-to-acceptable level. Further studies were needed to separately analyze the effectiveness of physical exercise on providing benefits for different levels of autism symptoms.

Unsteady Couette Flow of Dusty Fluid Past between Two Riga Plates
M. R. Islam and S. Nasrin
In this paper, the study analyzed on the unsteady laminar flow of heat transferable dusty fluid past between two parallel Riga plates. A uniform Lorentz forces have been influenced by Riga plates and also a constant pressure gradient is applied to the fluid. As per as Couette flow, the upper plate continues to move with a constant velocity, and the lower plate is kept fixed. The boundary layer approximations have been employed on the Navier-Stokes equation and Energy equation. The motion of the dust particles is governed by Newton's second law. A similarity transformation is applied to obtain the dimensionless form of the governing equations and used the explicit finite difference method to find its numerical solutions. The effects of the necessary parameters on the velocity and temperature distributions as well as the shear stress and Nusselt number of clean fluid particle and dust particles have been discussed in detail.
Keywords: Dusty Fluid, Riga Plate, Couette Flow, Explicit Finite Difference.

Introduction: Kaposi's sarcoma (MK) is most likely caused by human herpes virus type 8 (HHV-8) which develops particularly in individuals infected with HIV. This disease causes purplish or brownish tumors on the skin. Other organs can be affected, such as the mucous membranes, and the viscera. The goal of our study is to describe the epidemiological, clinical and therapeutic profile of this disease.
Chemotherapy has big interest in Kaposi sarcoma.
Methodology: This is a retrospective study conducted in the Medical Oncology Department at University Hospital Hassan II Center of FES about 13 patients over a period of 9 years from January 2010 to December 2018 to illustrate the service's experience in the management of Kaposi's sarcoma.
Results: The annual incidence of Kaposi disease in our department was very low, not exceeding three cases per year during the period studied. We have noted a male predominance with a sex ratio of 3,33. In our study, classical Kaposi disease was the most common form and presented in almost all patients with skin lesion in the form of papulonodules or purplish erythematous-angiomatous plaques. At the time of diagnosis, two patients had stage III and eleven patients had stage IV with visceral involvement according to the KRIEGEL classification. Chemotherapy was the standard treatment for almost all of our patients, other treatments such as surgery or radiotherapy were used in localized disease. The median progression-free survival of Kaposi disease treated in our department is 12 months and the average global survival of the Kaposi sarcoma extends to 52.95% over a 20-month follow-up.
Conclusion: In our department, we mostly found the classic form of Kaposi disease. Chemotherapy takes an essential place in the management of advanced cases. Better knowledge of signaling voices allowed the discovery of other therapeutic targets that may be promising in the future.

The Food and Feeding Habits of Asejire Reservoir Fish Species Diversity in South Western Nigeria
Augustine Omoike
Nigerian Asejire reservoir fish species resources and their food and feeding habit were studied for management purposes. 4 sampling zones were identified, back of reservoir wall, littoral area, middle of reservoir and industrial effluent discharge area. Research was carried out from August 2001 to July 2003 and 2016 to 2018 with grated fisher folks gillnet of 50.8mm, 63.0mm, 76.2mm, 114.0mm and 127.0mm mesh sizes for fish sampling during the wet and dry seasons. Catches collected were identified using morphometric and meristic features. The water assessed for physico-chemical parameters as described by American Public Health Association, stomach content of fishes caught were removed and preserved in 4% formalin, slit and analysed using numerical and frequency of occurrence method with selectivity coefficient (E) of the stomach content in relation to food available in the reservoir. The data collected were analysed using analysis of variance (ANOVA). 620 fish specimens were caught Chrysichthys nigrodigitatus was the most abundant single species. 18 fish species belonging to 12 families were identified and classified; the Family of Cichlidae was most divergent. The fish species caught were classified as herbivore feeders (plants and detritus); plankton feeder, Piscivores and omnivores (facultative) feeders.
Keywords: Asejire reservoir, feeding habit, stomach content, selective coefficient, mophometric features, Nigeria.

Foreign Aid and the Development Process: Some Reflections on the Nigerian Experience
Peter Ubi and Bassey Eb
The paper examines the link between foreign aid and the development process in Nigeria by comparing a 5-year average growth rate in foreign aid to that of some selected development indicators, namely: real per capita GDP, capital formation, infant mortality rate, secondary school enrolment, number of paved roads and discomfort index, bearing in mind the various government regimes and major policies and structural changes over the period 1980 to 2018. The overall correlation between foreign aid and the selected development indicators were also analyzed using correlation matrix. The results showed that: (i) aid-development relationship has mixed results in Nigeria when analyzed in different periods/regimes (ii) Periods with very high foreign aid inflows seem to support improvement in most of the development indicators. (iii) Health and education proxy by infant mortality rate and secondary school enrollment respectively appear to be more positively responsive to changes in foreign aid inflow than other development indicators like economic growth, capital formation, number of paved roads, etc. Based on these descriptive analyses/reflections, the paper recommended a higher aid inflow for Nigeria especially in health and the education sectors.
