the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...

Two Aedes aegypti (L.) populations were studied in the laboratory regarding the preference for three types of breeding sites, i.e., flasks containing only water, flasks with a plant and flasks with a stick. Each of these breeding units was placed in one cage and the choice of the oviposition sites was determined for individual females and three females per experimental unit at two humidity leve...

Fresh egg waffles are continuously baked in tunnel baking ovens in industrial scale. Waffles that partly or fully stick to the baking plates cause significant product loss and increased costs. The aim of this study was, therefore, to investigate the effect of different recipe ingredients on the sticking behavior of waffles. In this second part, ingredients investigated were different leavening ...

The ability of blind people to navigate through unfamiliar environments cannot but make us wonder. It also leads to philosophical problems, which Descartes already captured: No doubt you have had the experience of walking over rough ground without a light, and fnding it necessary to use a stick in order to guide yourself. You may then have been able to notice that by means of this stick, you co...

World Health Organization reports in the World Health Report 2002, that of the 35 million health-care workers, 2 million experience percutaneous exposure to infectious diseases each year. In addition, it shows that 37.6% of hepatitis B, 39% of hepatitis C and 4.4% of HIV/AIDS in health-care workers around the world are due to needle stick injuries [1]. During 2002 to 2007, it has been reported ...

Résumé. Using a high speed camera, we study the peeling dynamics of an adhesive tape under a constant load with a special focus on the so-called stick-slip regime of the peeling. It is the first time that the very fast motion of the peeling point is imaged. The speed of the camera, up to 16000 fps, allows us to observe and quantify the details of the peeling point motion during the stick and sl...
