Many fields of science such as astronomy and astrophysics require the visualization and editing of smooth, continuous volume data. However, current high-level approaches to volume editing concentrate on segmentable volume data prevalent in medical or engineering contexts, and therefore rely on the presence of well-defined 3D surface layers. Editing arbitrary volumes, on the other hand, is curre...

The effect of Positive End Expiratory Pressure (PEEP) on the hepatic elimination of low to moderate extraction ratio drugs has not been clearly defined. We prospectively investigated the effect of PEEP on the clearance of theophylline in 30 (20 males and 10 females) intubated critically ill adult patients with acute lung injury/acute respiratory distress syndrome (ALI/ARDS). The Mean (±SD) age ...

Tree bark species were randomly collected from 65 sites having different anthropogenic activities, such as industrial, high traffic commercial, residential high and residential low traffic volume areas of Ibadan City, Nigeria. Levels of Cd, Cu, Pb, Zn, Co, and Cr of the dry-ashed bark samples were determined by AAS. The mean metal concentrations (mg kg(-1)) in samples from industrial zone were ...

• Generalised difference in differences is used to examine effects of LTN. LTNs reduced NO 2 both within intervention areas (5.7%) and boundary (8.9%) Traffic volumes were by 58.2% 13.4% at LTN sites. restriction measures may create safer healthier places for community members but also displace traffic air pollution surrounding streets. Effective urban planning depends on understanding the magn...

this experiment was conducted to determine the effect of using l-threonine and reducing dietary levels of crude protein (cp) on egg production criteria in layers. three hundred of hy-line w36 laying hens were used in this experiment. this experiment consisted of three experimental treatments with five replications in each. experimental treatments included 3 diets with different levels of cp whi...

High-performance polymers that have improved processing characteristics, and a method of making them, have been invented. One of the improved characteristics is low (relative to corresponding prior polymers) melt viscosities at given temperatures. This characteristic makes it possible to utilize such processes as resin-transfer molding and resin-film infusion and to perform autoclave processing...
