The caudal part of the neural tube developed into the spinal cord at 1.5 cm CVRL (35 days) with clearly differentiated ependymal, mantle and marginal layers. From 6.4 cm CVRL (57 days) onwards, cilia were present on the ependymal cells lining the central canal. At the same stage, the mantle layer appeared at the roof and floor plate. It showed different stages of developing neurons and supporti...

The existence of specific expansive minerals in the clay soil related to the climatological conditions, seasonable variation of rainfall precipitation (wet and dry periods) and fluctuation of water table in Mediterranean countries, has resulted to induce unexpected shrinkage and swelling movements with all the unfavourable consequences. It was observed that light industrial structures and small...

In this study, the physical and economic impacts of four policy measures (crop diversification, improved watershed development, canal lining reducing level reliability) all designed to improve bulk water supply, are assessed in a case study Musi catchment India. The aim is compare these have on amount supplied net returns across complex multi-nodal catchment. It argued that because it policymak...

Introduction: The incidence of cholesteatoma occurring as a result of tympanoplasty is extremely rare. Understanding the cause and preventing its occurrence in the future is the main intention of highlighting this peculiar presentation.   Case Report: A 25-year-old woman presented with progressive hearing loss and blocked sensation in the left ear of one and a half month...

Owing to the potential negative impacts of climatic changes and grand Ethiopian renaissance dam, water scarcity has become an urgent issue. Therefore, Egyptian Ministry Water Resources Irrigation started a national project lining rehabilitation canals, reduce seepage losses for efficient resource management. This study presents new approach assessing three different crack techniques Ismailia ca...

Structural features of the extarnal ear form a number factors that affect course inflammatory and scar processes. A strong difference in structure external requires an individual approach, taking into account their structure. To maintain normal functioning, has specialized defense mechanisms, such as presence ceruminous glands, weak acidic environment with bactericidal properties, special epide...

the joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. therefore, the bending moment act...
