Dichloromethane Injection: Case Report

Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at hi...

The Second-Knowledge Mechanism

In settings of incomplete information, we put forward a very conservative —indeed, purely set-theoretic— model of the knowledge that the players may have about the types of their opponents. Yet, we prove that such knowledge can be successfully and robustly leveraged by means of a very strong solution concept: in essence, via extensive-form mechanisms under mutual knowledge of rationality. We de...

the impact of training on second language writing assessment: a case of raters’ biasedness

چکیده هدف اول این تحقیق بررسی تأثیر آموزش مصحح بر آموزش گیرندگان براساس پایایی نمره های آنها در پنج بخش شامل محتوا ، سازمان ، لغت ، زبان و مکانیک بود. هدف دوم این بود که بدانیم آیا تفاوتهای بین آموزشی گیرندگان زن و مرد در پایایی نمرات آنها وجود دارد. برای بررسی این موارد ، ما 90 دانشجو در سطح میانه (متوسط) که از طریق تست تعیین سطح شده بودند انتخاب شدند. بعد از آنها خواستیم که درباره دو موضوع ا...

LES of atomizing spray with stochastic modeling of secondary breakup

A stochastic subgrid model for large-eddy simulation of atomizing spray is developed. Following Kolmogorov!s concept of viewing solid particle-breakup as a discrete random process, atomization of liquid blobs at high relative liquid-to-gas velocity is considered in the framework of uncorrelated breakup events, independent of the initial droplet size. Kolmogorov!s discrete model of breakup is re...
