diabetes mellitus is a progressive disease. most investigators have focused on glomerular changes in diabetic kidney and non-glomerular alterations have been less attended. the present study has been conducted to find early non-glomerular histological changes in diabetic renal tissue. twenty male wistar rats weighting 200-250 g were used for the diabetic group. diabetes mellitus was induced by ...

nowadays novel is one of the most important patterns of story writing and indeed is an image of real life and the era that it was written in. the present article studies an era of social and political life of egyptians by studying “in darkness” as a novel written by najib alkeilani who is an egyptian contemporaneous author. najib alkeilani wrote this novel when he was in prison in 1957 ad.

Traditional approaches for the seismic retrofit of existing buildings consider the following assumptions: (a) the building is not damaged after a minor earthquake, (b) the building is reparable after a moderate earthquake, and (c) the building will not have collapsed after a severe earthquake. In recent times, following several destructive earthquakes which have occurred in the past decades, th...

Liquid storage cylindrical containers are built for storing a variety of liquids. The seismic behavior of tanks is, however, quite complex problem. The interaction of tank and liquid can be simplified with the concept of generalized single-degree-of-freedom systems representing the convective, rigid impulsive and flexible impulsive vibration modes. This paper presents the theoretical background...

This article presents a distributed nondominated sorting genetic algorithm II (NSGA-II) for optimal seismic retrofit design using buckling restrained braces (BRBs) on a cluster of multi-core PCs. In the formulation, two conflicting objective functions of the initial BRB installation cost required for seismic retrofitting and damage cost that can be incurred by earthquakes expected during the li...

1. ABSTRACT Devices which can add damping and strengthen structural systems, without changes to the existing components, were found recently extremely useful in retrofitting lightly reinforced frames and other structures. Some damping devices were developed purposely for building structures, however, many more were adapted from use in other industries such as the military and aerospace. Damping...

High-resolution seismic reflection has been used successfully to characterize material and investigate a variety of problems associated with earthen dams and abutments. Limitations and challenges of seismic reflection when interrogating these structures and lithologies are nontrivial and require very critical thinking. Seismic reflection has proved an effective tool for mapping confining units ...

This paper presents an optimization process for the design of a novel synergetic seismic and energy retrofitting strategy that combines favorable mechanical properties timber attractive thermal insulation bio-based materials. The method, defined as Strong Thermal Seismic Backs (STSB), comprises attachment frames panels on vertical envelope facade walls existing masonry buildings, thus improving...
