This paper presents a study of the relationship between Electrical Discharge Machining (EDM) parameters on the EDM efficiency factors using a full factorial design, based on pulse on-time, duty cycle and tool polarity parameters in EDM machining of AISI H13 tool steel. The results show that, in positive polarity, the plasma flushing efficiency and pulse efficiency increase according to the puls...

Sediment detention basins are implemented on mountain rivers to trap solid material that may aggravate the flooding of downstream settlements. However, retention structures built in past unnecessarily retain sediment during non-hazardous flood events, resulting high maintenance costs and deficit downstream. In addition, so-called spontaneous self-flushing previously retained floods has occasion...

This study explored drinking patterns, alcohol-related flushing, and ways students themselves and other people respond to flushing in drinking situations. Of 1080 Chinese undergraduate university students given the survey questionnaire, 725 (67.1%) returned the completed surveys. Eighty percent of the students were drinkers (93% of males and 69% of females); 68% of the drinkers were flushers. M...

Aim: This paper describes Chinese university students' understanding of the meaning of the alcohol-related flushing response and how they reacted to their own and someone else's flushing in a group drinking situation. Method: The researcher surveyed 530 Chinese university students about their understanding of flushing and their perception of how people respond to a person who visibly flushes wh...

Abstract A vortex tube ejector comprises a with slitted crown that lies flush across the entire width of channel bed surface. The and suspended loads are ejected minimal flushing water through slit same efficacy as any other alternative extractor. whirling flow phenomena duct very complex, so ordinary classical models have results contrary to required design guidelines. So, machine learning (ML...

A sediment quality survey was conducted in the Florida Panhandle (Panhandle) over a period of 10 years (1992 to 2001). The survey examined which dioxin and furan compounds may be present in sediments of the bay systems, their locations, and concentrations. The U.S. Fish and Wildlife Service (FWS) collected and analyzed 29 sediment samples from 6 bay systems across the Panhandle. Risk associated...

Facial flushing after the ingestion of alcohol is common among Asians. Flushers are genetically less able to tolerate alcohol than nonflushers and are less likely to become alcoholics. This study examined whether lower consumption of alcohol among flushers was correlated with cultural factors such as embarrassment over flushing as well as with biological factors among Japanese in Japan and Japa...

[1] Metabolic activity and biogeochemical diversity within cryoconites from the Canada, Commonwealth, Howard, and Hughes glaciers in the McMurdo Dry Valleys revealed the presence of a productive microbial refuge in this polar desert ecosystem. Fluorescent in situ hybridization showed a high percentage of Cytophaga-Flavobacteria cells in cryoconite sediments (87.2%), while b-Proteobacterial cell...
