Ambient Temperature and Mortality From Unintentional Cocaine

Mean number of fatal unintentional cocaine overdoses in New York.. Second, we do not know the exact ambient temperature to which the.

Likewise, the proportions with positive toxicology test results for benzodiazepines, barbiturates, or salicylates on hot days were 10.3%, 1.2%, and 0.9%, respectively, compared with similar proportions as those who died on other days, which were 11.5% (benzodiazepines), 1.4% (barbiturates), and 1.3% (salicylates). Opiates were detected in 57.1% of cocaine overdose cases on hot days compared with 61.7% of such cases on other days. Of the 341 subjects who died of cocaine overdoses on hot days, the proportion that had positive toxicology test results for ethanol was 42.9%, compared with 41.4% for the 1667 subjects who died on other days.

However, for most persons the temperature is a more readily interpretable variable.

Maternal Exposure to Ambient Temperature and the Risks of

In Greece, mean ambient temperature was reported to be negatively correlated .. The addition of other air pollutants did not improve Akaike's.

We considered 2-sided P values less than 0.05 to be statistically significant. To avoid problems arising from collinearity from multiple air pollutants, we included one air pollutant at a time in the survival models. We assessed goodness of fit by ranking the models according to Akaike's Information Criterion. We estimated the correlation between weekly exposures using Spearman's correlation (since some of the pollutant distributions were skewed). The plot of residuals was random, with no discernible pattern, indicating that the model was an adequate fit.

Popular model heavy frame industrial gas turbines were compared with similarly sized Wärtsilä engines, with capacities of 200 – 275 MW in simple cycle, and approximay 300 MW in combined cycle (see fact box at end of article for full load output of the specific models compared). The performance of simple cycle gas turbines, combined cycle gas turbines (CCGT) and Wärtsilä combustion engines at varying ambient conditions was assessed using data from GT PRO.

What is Wet-Bulb Temperature?

What does ambient temperature mean

Definition - What does Wet-Bulb Temperature mean? Wet-bulb Wet-bulb temperature is actually the function of ambient air temperature and relative humidity.

Wet-bulb temperature is the lowest level of temperature that can be obtained through evaporative cooling of a ventilated surface covered with ice or wet with water.

Lower levels of wet-bulb temperature indicate that the air could carry higher amounts of water vapor compared to higher levels of wet-bulb temperature. This type of temperature measures the amount of water vapor that the atmosphere is capable of holding at certain weather conditions. Wet-bulb temperature is actually the function of ambient air temperature and relative humidity.

One example is in the selection of cooling cell towers. Accurate measurement of wet-bulb temperature is very important in various industries. This is to avoid things that may cause corrosion damage such as scale accumulation, improper flow of water as well as loss of air flow throughout the surfaces where there is heat exchange. With this, the wet-bulb temperature of the facility or area involved should be followed.

It indicates a temperature that is near thermodynamic or real temperature. It is the lowest level of temperature reachable under present ambient conditions brought by water evaporation.

For specific air parcels at a known dry-bulb temperature and pressure, the true wet bulb temperature resembles the distinct values of dew point temperature as well as relative humidity.
