The control of major accident hazards linked with the storage and processing of dangerous substances in chemical and petrochemical installations is regulated in the European Union by the so‐called “Seveso II Directive.” One of the requirements in this Directive is the declaration of not only the hazardous substances as present onsite, but also any hazardous products that could form during a loss of control situation.
This study focused on the development of an experimental technique to determine the substances that might be formed during an uncontrolled chemical reaction or runaway reaction. The decomposition reaction of a diazo compound was studied with the technique to assess its applicability.
The results show that, apart from its applicability in relation to the Seveso II Directive, the same technique can be used to obtain data for the design of gas treatment systems or to study the mechanism behind runway reactions. Understanding this mechanism, in turn, helps to identify conditions that might favor the occurrence of, or might temper the course of, the runaway reaction.
Traditionally, materials characterization instrumentation has focused mainly on particles. However, for a better fundamental understanding and various potential applications, it requires an increase in the ability of instrumentation to observe.Characterization and manipulation requires not only extreme sensitivity and accuracy, but also atomic level resolution. In this regard, it is noteworthy the importance of the central role that the various modes of microscopy play in materials characterization and measurement.Also, are particularly relevant physical properties and short-range forces, but do not play a prominent role in the characterization at the macroscopic level, represent a significant impact on the nanometer scale.The sample is studied, are the connections of the RAM, from an IBM 450.The sample characterization was performed at the scanning electron microscope of the Research center in Engineering and Applied Sciences (CIICAp) of the Autonomous University of the State of Morelos (UAEM), is observed in the presence concentrate gold, nickel and carbon.In the scanning electron microscope has the research center, we have observed the presence of gold particles included in the RAM, the particles represent 90.20% by weight, there are also carbon particles containing nickel and 1.94 and 7.86 wt% respectively.
N-fixing legume crops may be a good component of a general plan to improve cropping system efficiency. For this purpose, crop suitability to specific environments must be established. Vicia faba and Pisum sativum, 1991). In the family of models produced it will select those that best express the crop phenologic response in different phenologic stages.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
