More than two decades ago, attention was called to the uncontrolled spread of injecting drug use in many Asian countries and the virtually unnoticed but rapid spread of HIV among those who were injecting [1]. It was pointed out that constantly changing trafficking routes from the Golden Triangle were exposing new populations to the use and subsequent injecting of heroin, that these populations ...
The introduction of inductive storage/opening switCh pulse forming networks as an operational reality in the llUllti-megajoule, sub-microsecond range, makes possible the design and operation of very large high power systems at modest cost.l• 2 The operational simplicity and economy of the pulse shortening system shifts the emphasis from opening switches to that of finding suitably simple, highl...
purpose: in recent years high explosive bomb attacks have been increasingly directed against civil structures by various terrorist organizations. this paper describes a numerical method for assessing the interaction of high explosive air blast within the complex geometrical type of a congested urban environment. materials and methods: the first step in predicting blast effects on a targ...
introduction acute poisoning by oral ingestion of mixed hazardous materials can lead to multiorgan toxicity and may represent a special challenge in clinical management, in particular if little is known about the effects of the involved agents. this is especially true when industrial chemical substances have been swallowed, as a huge variety of toxic substances must be taken into account. concl...
Emulsion explosive is a form of water in oil emulsions. They include a mixture of fuel and oxidizer and other components. Emulsions are a new type of industrial explosive materials. Because of the stability, high safety and well explosive performance, are used as a powerful and inexpensive source of energy in agriculture, water conservancy, transportation, mining, building materials and etc. So...
Introduction: The purpose of this study was to predicting intermittent explosive disorder on the basis of aggression, negative emergency and alexithymia. Method: This research was a correctional descriptive study. The statistical population of this research includes all Prisoners of the central prison of Rasht city are in 2017. The sample consisted of 350 prisoners that were 175 people with in...
Abstract: The purpose of this study is to produce scarf joint through explosive welding process (EXW). The scarf weld is a process in which the final bond interface is oblique. With applying the explosive welding technique, this joint can create a metallic bond between similar or dissimilar metals. In this study, chamfered end of aluminum and copper plates were joined explosively and named scar...
Aluminum base composites are manufactured in a variety of methods, such as mixing in liquid state, mechanical alloying and so on. Explosive welding is one of the modern ways of producing Aluminum base composite. Explosive welding is used for excellent bonding of similar and dissimilar materials with a wide variety of thicknesses, area dimensions and different thermal and mechanical properties. ...
the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...
