Нейротоксичность анестетиков и седативных средств и их влияние на послеоперационные дезадаптивные расстройства поведения в педиатрической анестезиологии (Письмо в редакцию)

Neurotoxicity of anaesthetics have become one of the most discussed problems in paediatric anaesthesiology. The experimental studies on animal models have shown that the anaesthetics used in general anaesthesia should have an influence on neurodegenerative processes, neuroapoptosis and the irregulated death of the neuronal cells. Because of this fact, scientists are trying to discover the possibilities of how to minimize the adverse effects of anaesthesia and revise the other alternatives of prevention of anaesthesia-induced maladaptive behavioural disorders.Нейротоксичность анестетиков стала одной из наиболее обсуждаемых проблем в детской анестезиологии. Экспериментальные исследования на животных моделях показали, что анестетики, используемые при общей анестезии, должны влиять на нейродегенеративные процессы, нейроапоптоз и нерегулируемую гибель клеток нейронов.В связи с этим ученые пытаются найти возможности минимизации негативных эффектов анестезии и изучить альтернативные способы профилактики дезадаптивных поведенческих расстройств, вызванных анестезией

Impact and post impact behavior of fabric reinforced geopolymer composite

International audienceImpact and post impact behavior of fabric reinforced geopolymer composites is investigated in this study. Carbon, E-glass and basalt fabrics are incorporated in the geopolymer matrix. The geopolymer composites are tested for impact resistance to an out-of-plane low velocity impact test, followed by post impact performance testing using residual strength measurement on the sample. Impact properties such as impact energy, energy absorption capacity, and damaged area of the composites were examined for fabric reinforced geopolymer composite samples. The drop weight impact tests were performed on composite samples of 15 × 15 cm. The quality of the samples was examined using C-scan in ultrasonic vibration mode and μCT before and after impact test. The post impact behavior of the composite samples was characterized using four point bending tests. Fiber orientation and alignment was observed using SEM. The results obtained showed that E-glass fabric reinforced composites show slightly better performance than carbon reinforced composites. Especially the damaged area is smaller for E glass composites. Basalt fabric reinforced composites have low bending strength and very low impact resistance. The energy absorption in E-glass is due to post-debond fiber sliding phenomena and in carbon fiber to fiber pull out from the composite. The smaller damaged area is attributed to the higher elastic energy absorption of E-glass fibers. The residual strength of carbon and E-glass composites decreased in relation to the size of the visually damaged area, meaning that no invisible damage took place. © 2016 Elsevier Lt
