Проектирование системы электроснабжения домостроительной компании с детальной проработкой арматурного цеха

В данной работе проектируется система электроснабжения домостроительной компании с детальной проработкой арматурного цеха, а также приводятся, технико-экономические обоснования принятых решений. В разделе "Социальная ответственность" проводится оценка условий труда, анализ вредных и опасных факторов, разработка мер защиты от них. В разделе "Финансовый менеджмент, ресурсоэффективность и ресурсосбережение" приводится оценка коммерческого потенциала и перспективности проведения научных исследований, определение возможных альтернатив проведения научных исследований, отвечающих современным требованиям в области ресурсоэффективности и ресурсосбережения.In this work, the power supply system of a house-building company is being designed with a detailed study of the reinforcing shop, and also gives feasibility studies for the decisions made. The section “Social Responsibility” assesses working conditions, analyzes harmful and dangerous factors, and develops protection measures against them. The section “Financial Management, Resource Efficiency and Resource Saving” provides an assessment of the commercial potential and prospects of conducting scientific research, identifying possible alternatives for conducting scientific research that meet modern requirements in the field of resource efficiency and resource saving

Neurotransmitter and amino acid analysis and ultrastructural observations of fetal brain cortex transplantation to adult rat brain under the effect of dexamethasone

OBJECTIVE: To conduct an investigation of fetal cortical tissue graft survival using transmission electron microscopy and analyzing neurotransmitters and amino acids and their function, with special reference to the effect of dexamethasone

Experimental trigeminal glycerol injection in dogs: Histopathological evaluation by light and electron microscopy

We investigated the effects of percutaneous gasserian glycerol injection in dogs and reviewed the histopathological changes. Experiments were performed in 16 adult healthy mongrel dogs. In group 1 (8 dogs) normal saline and in group 2 (8 dogs) pure glycerol was injected in the right trigeminal ganglion. After these procedures, dogs in each group were sacrificed after 24 h (3 dogs), 7 days (3 dogs), 21 days (2 dogs). The trigeminal ganglion and nerve of both sides were removed by using microsurgical techniques and examined by light and electron microscopy. Group 1: in all sections, nerve cells, myelinated and nonmyelinated fibers revealed normal patterns with slight fibrosis. Group 2: in all sections, myelinated fibers showed disintegration and swelling of the myelin sheath, rupture of axon continuity, destruction of basal lamina, deformation of the myelin-axon relationship by both light microscopy and electron microscopy. The sections examined by electron microscopy also showed axonolysis in nonmyelinated fibers. The changes after 7 and 21 days were less prominent than after 24 h. In the left sides, there are no pathological changes. Glycerol has a neurolytic effect on the dog's trigeminal ganglion. These effects were not specific and selective for myelinated and nonmyelinated nerve fibers. Copyright (C) 2002 S. Karger AG, Basel
