The facilities in Syria are destroyed and damaged by terrorist acts
of armed groups. Therefore, the construct managers should
rehabilitate it logically and economically. This required accurate
data about the structural nature and functional condit
ions of the
construct. However, the personal estimation of experts and the
approximate structural conditions and functionality of construct for
rehabilitation- inclines the decision makers from getting the exact
estimate of the rehabilitation degrees. Therefore the aim of this
research is to propose a set of indicators and criteria that can
assist in selecting the construct that required to be rehabilitated
according to its levels.
This research deals with the study of the behavior of piles under the influence of seismic loads through (3D) modeling using FE-Method-program (ABAQUS) with special reference to the most important parameters affecting the displacements and internal f
orces generated in piles. This study has been completed in two phases: the first phase is a case study of the single Pile (reference case), where a study of the behavior of a single pile assigning structure is modeled with a degree of freedom. The parametric study results show that the presence of structure causes the application of a large load in the upper part of the pile resulting from the impact of inertia dominating the kinetic effect. The forces of inertia increases with the increasing mass of structure, and when the frequency of structure nears the frequency of seismic load. The second phase deals with the study of the situation of the group of piles, where the study handles the effect of a number of piles, piles spacing, and locations on the internal force and displacements generated in the piles. The parametric study results have shown for this phase of this research that an increase the number of piles in the group causes a significant increase of internal forces generated at the top of the pile and a slight decrease for those forces in the central part of the pile, that seismic loads are not distributed equally for all piles, and that corner piles are subject to greater loads while mid. Piles are subject to less load.
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital
anomaly. It presents predominantly in infancy with features of myocardial ischemia or cardiac failure and
may be mistaken for common pediatric cond
itions such as colic, reflux or bronchiolitis. With early
surgical correction the prognosis is good. In this report we present unusual case of a 5-year-old female
with an anomalous left coronary artery arising from the pulmonary artery (ALCAPA) presenting with
chest pain,dyspnea and palpitation during physical exertion.Trans-thoracic echocardiography and
coronary angiography revealed an anomalous origin of the left coronary artery with mitral regurgitation .
She subsequently underwent successful surgical technique where the left internal thoracic(mammary)
artery was used to revascularise the left main coronary artery which is considered as the first unique
procedure in children. Excellent surgical results were obtained and the patient was discharged from the
hospital without complaints.
Samples of surface sediment of St. Johns River Basin were collected,
extracted and their aliphatic hydrocarbons (AH) were determinated
quantitatively and qualitatively by GC-FID and GC-MS Techniques, were used
to characterize the (AH) hydrocarbons
homologous and biomarker
compounds.The sediments contained high organic matter content, while the
hydrocarbons AH represented ٠,٣٥-٢,٧٢٪ of the total organic matter (TOM)
found in sediments.
