through this article, the distribution of air pollutants in tehran have been simulated based on wind patterns with and without the presence of synoptic by tapm (a meso-scale model). the simulation covers three horizontal resolution domains 30, 15 and 5 kilometers. the pollutants chosen for this are co and pm10 and wind data is 10 meter height level. the result has shown that the model simulated...

mean tropical state driving El Niño events for this analysis. Table 1 shows that knowledge of these quantities averaged over a 50-year window is not sufficient to determine the ENSO variability over the same window–developing more sophisticated metrics is a crucial goal of the proposed research. Nonetheless, simple lag-correlation analysis of NINO3 index and eastern Pacific thermocline depth (l...

We studied behavioral indicators of poor welfare in shelter dogs. Our research question was: How is the welfare of shelter dogs affected by length of stay at a shelter, age, sex, and breed? Data were collected on 18 dogs from October 2016 to March 2017 at a small private shelter in Marietta, GA. Data were collected in 15-minute sessions when the dogs were in their indoor enclosures. No signific...

OBJECTIVE To describe changes in WBC counts, plasma cortisol concentration, and fecal parasite shedding of dogs housed in an animal shelter and determine the effects of daily petting sessions on these variables. DESIGN Hybrid prospective observational and experimental study. ANIMALS 92 healthy dogs newly arrived to an animal shelter and 15 healthy privately owned dogs (control group). PRO...

Millions of dogs enter animal welfare organizations every year and only a fraction of them are adopted. Despite the most recent American Pet Products Association (APPA) data that nearly half the US population owns a dog, only 20% acquired their dog from an animal welfare organization. Studies show that people consider adopting from an animal shelter more often than they actually do, which indic...

5) Two metrics were evaluated to determine trends over the past twenty years. The first metric is the Accumulated Cyclone Energy (ACE) index, which is the maximum sustained wind speed squared at six-hour intervals. ACE represents an approximation of the kinetic energy generated by a tropical cyclone. ACE correlates globally at 0.97 with Emanuel’s PDI index which is the wind speed cubed at six-h...

PURPOSE Estimating wind chill index as one of the indexes effective in body comfort, specifically for athletes and tourists interested in winter sports. METHODS Meteorology data including temperature and the percentage of relative humidity of 6 synoptic stations of Chaharmahal-Bakhtiyrai province, Iran from 1990 to 2007 were extracted from Iranian Meteorology Site. In order to calculate the v...

The use of public shelters in Philadelphia was examined both before and after the implementation of Act 35, Pennsylvania’s response to the Personal Responsibility and Work Opportunity Reconciliation Act of 1996. Univariate interrupted time-series analyses were conducted to determine if trends in shelter utilization (the number of families admitted, by family size, by race, by age of household h...

In this article, I describe efforts to manage the capacity of homeless shelter programs in Philadelphia and assess the impact of those efforts on providers and consumers of homeless services. Most reforms have focused on reducing the capacity of the shelter system by reducing the average length of stay of persons in shelter and by providing housing relocation assistance. However, these reforms ...
