Исследование кинетики процессов пиролиза и газификации углей

Объектами исследования являются каменные и бурые угли и антрацит Кузнецкого и Канско-Ачинского месторождений. Цель работы – исследование кинетики процессов пиролиза и газификации и определение энергии активации исследуемых углей. В процессе исследования проводились измерения плотности и термогравиметрический анализ исследуемых углей, классификация моделей и расчет энергии активации, а также кинетических параметров углей, построение ТГ-кривых и зависимостей энергии активации от степени конверсии, сравнительный анализ результатов расчета.The objects of study are bituminous coal, lignite and anthracite from Kuznetsk and Kansk-Achinsk deposits. Objective - study of the kinetics of pyrolysis and gasification processes and the definition of the activation energy of the investigated coals. During the study we measured density and thermal gravimetric analysis, classifyed models and calculating the activation energy and the kinetic parameters of the coals, the construction of the TG curves and activation energy dependency on the degree of conversion, comparative analysis of the results of calculation

The role of open abdomen in non-trauma patient : WSES Consensus Paper

The open abdomen (OA) is defined as intentional decision to leave the fascial edges of the abdomen un-approximated after laparotomy (laparostomy). The abdominal contents are potentially exposed and therefore must be protected with a temporary coverage, which is referred to as temporal abdominal closure (TAC). OA use remains widely debated with many specific details deserving detailed assessment and clarification. To date, in patients with intra-abdominal emergencies, the OA has not been formally endorsed for routine utilization; although, utilization is seemingly increasing. Therefore, the World Society of Emergency Surgery (WSES), Abdominal Compartment Society (WSACS) and the Donegal Research Academy united a worldwide group of experts in an international consensus conference to review and thereafter propose the basis for evidence-directed utilization of OA management in non-trauma emergency surgery and critically ill patients. In addition to utilization recommendations, questions with insufficient evidence urgently requiring future study were identified.Peer reviewe
