Performance Evaluation of Abergelle cross Boer goat breed under farmer management system in case of Tanqua Abergelle wereda
41 (31 females and 10 males) 50% Boer and 50% Abergelle crossbred goats were distributed to evaluate and compare their kids growth performance, farmers' perception and their survivable rate under farm management system. Housing, feeding and health care were thoroughly attended. The average BW, WW, SMW and NMW of the crossbred (25% Boer and 75% Abergelle) male and female kids were (2.68 kg, 2.62 kg),(12.17 kg, 11.95 kg)and (18.25 kg, 17.38 kg) respectively. While, the local kids average BW, WW, and SMW were (2.30kg, 2.23kg), (10.5kg,10.5kg) and (14.17kg,13.38kg) for male and female respectively. The result indicated that crossbred body weight increment at different growth stage was better than the local breed. Farmers were also perceive the crossbred goat have docile behavior which easily adopt for zero grazing, non selective and voracious in feeding and high growth rate, even though they criticize as short in body length and lowest disease resistant. The survivable rate of the crossbred kids at pre weaning and post weaning were 90.7% and 97.4% respectively which more related to low disease resistance. So that with applying of good management practice scaling up activities has to be strengthened to make farmers better benefited from Abergelle cross Boer goat breed.

Development of Corrosion Resistant Platings for BiPolar Plates of Proton Exchange Membrane (PEM) Fuel Cells – A Review
Bipolar plates (BPs) are a key component of Proton Exchange Membrane (PEM) Fuel Cells with multifunctional character. They uniformly distribute fuel gas and air, conduct electrical current from cell to cell, remove heat from the active area, and prevent leakage of gases and coolant. Bi-Polar Plates also significantly contributes to the volume, weight and cost of Proton Exchange Membrane Fuel Cell stacks. Hence, there are vigorous efforts worldwide to find suitable materials for Bi-Polar Plates. The materials include non-porous graphite, coated metallic sheets, polymer composites, etc. This paper reviews various types of materials, in use and proposed, for Bi-Polar Plates and critically examines their physical and chemical properties.

Behavioral Analysis of HIV Epidemic Model in a Post- Eclipse Stage
In this works, Human Immunodeficiency Virus (HIV) epidemic model including an eclipse stage of infected cells with latently infected cells was considered. The local and global stability of the system were established using the associated basic reproduction number .Bifurcation analysis was used to establish conditions for the local stability of the endemic equilibrium using the centre manifold theorem. The result shows that the disease free equilibrium is locally and globally asymptotically stable, when the associated disease threshold parameter is less than unity, and the system exhibit backward bifurcation. Numerical Simulations carried out for the analytical result suggest that the attack to the latently infected cells cannot be ignored because some quicker cells from this stage will move with time to productively infected class/cells. Keywords: HIV model; Basic reproduction number; sensitivity analysis; backward bifurcation;

Effect of a neurodevelopmental treatment based on physical therapy protocol for infant with Russel-Silver syndrome: A case report
The Russell-Silver syndrome is a rare genetic disease, with various clinical presentations. Little is known about its developmental delay and methods of treatment in the literature. The aim of this study was to evaluate the effect of physical therapy to treat a child with developmental delay caused by Russell-Silver syndrome. The intervention was performed over a period of one year, during 1-hour, twice a week, at the University Hospital of the Federal University of Sergipe (UFS). Motor performance and functional capacity were assessed by using the Inventory of the Pediatric Evaluation of Disability (PEDI). Data were analyzed quantitatively, comparing pre-and post-treatment measures. After the intervention, there was a significant increase in scores for analysis in the areas of self-care and social function. In the area of mobility, the scores also increased, showing an improvement of the engine and consequently higher degree of functionality of the child, but the infant kept showing a lower level of development when compared with typically developing children at the same age. Physical therapy was an efficacious method of intervention, enhancing and acelerating the motor and functional development in a infant with Russell-Silver syndrome.

The Effect of Organizational Culture on Organizational Economic Performance
The main objective of this paper was to look at the effect of Organizational Culture on Organization’s Economic Performance. The discussion was based on series of empirical studies of Organizational culture and Organization’s Economic performance. The research findings no doubt have validated the synerginous relationship between Organizational culture and Organization’s Economic performance especially, the long-term financial performance was highest for organizations with an adaptive culture while strength and fit perspectives were partially supported. They also recommended that there can still be more room for improvement and consequently better economic performance if proactive adaptability is enhanced, which requires senior leaders to cooperate and collaborate among themselves, leaders must create and implement a business vision and associated strategies that fit the organizational context( a vision represents a long-term goal that describes” what an organization wants to become”) , if adaptive culture is promoted over time by a combination of organizational success and specific leadership ,leaders must get employees to buy into a timeless philosophy or set of values that emphasizes service to the organization’s key constituents-customers, stockholders, and employees-and also emphasizes the improvement of leadership, and creating infrastructure to preserve the organization’s adaptiveness by consistently reinforcing and supporting the organization’s core philosophy or values of satisfying constituency needs and improving leadership by management.
