Daily exposures to ambient oxides of nitrogen were estimated here for residents of Hillsborough County, FL. The 2009 National Household Travel Survey provided geocoded data on fixed activity locations during each person-day sampled. Routes between activity locations were calculated from transportation network data, assuming the quickest travel path. To estimate daily exposure concentrations for...

The Mean Residence Time is a quantity which used very often to characterise chemical reactors. This can be calculated using the Distribution of specific, continuous reactor and assuming closed-closed boundary conditions. Many reactors in industry though, are discontinuous ones direct application these methods general not possible. work presents new distribution, Local Distribution, observes eac...

The pharmacokinetics of total and free prednisolone (PSL) in six healthy men, with or without pretreatment with oral glycyrrhizin (GL), was investigated to confirm whether oral administration of GL influences the metabolism of PSL in man. Each subject received an intravenous administration of 0.096 mg/kg of prednisolone hemisuccinate (PSL-HS) with or without pretreatment with 50 mg of oral GL f...

Resistance training is considered less effective than endurance training in lowering plasma triglyceride (TG) concentrations. Acutely, however, a single bout of strenuous exercise, whether endurance or resistance, increases the efficiency of very low-density lipoprotein (VLDL)-TG removal from the circulation and leads to hypotriglyceridemia. The comparative effects of these two types of exercis...

BACKGROUND The effects of surgery on gastric emptying have been documented for a considerable time, but less is known about the effects in the small intestine. It is thought that there is minimal diminution in the absorptive capacity of the small intestine after operation, although there is no literature on drug absorption in the early period after surgery. This study investigated drug absorpti...

A bioavailability and pharmacokinetics study of doxycycline was carried out on 30 healthy ostriches after a single intravenous (IV), intramuscular (IM) and oral dose of 15 mg/kg body weight. The plasma doxycycline concentration was determined by HPLC/UV at 0 (pretreatment), 0.08, 0.25, 0.5 1, 2, 4, 6, 8, 12, 24 and 48 h after administration. The plasma concentration-time curves were examined us...

In order to better understand the role of the uid behavior in CMP, we measured slurry transport beneath a glass wafer. We quanti ed the slurry transport using Residence Time Distribution techniques and two measures of slurry transport e ciency de ned as the percentage of new slurry beneath a wafer. Slurry transport e ciency depended on platen speed, ow rate, and the conditioning method. We foun...

We experimentally analyze the behavior of a non-Markovian bistable system with noise, using a vertical cavity surface emitting laser with time-delayed optoelectronic feedback. The effects of the delayed feedback are observed in the probability distribution of the residence times of the two orthogonal polarization states, and in the polarization-resolved power spectrum. They agree well with rece...
