The insect repellents 3535 (ethyl butylacetylaminopropionate or IR3535) and deet (N,N-diethyl-3-methylbenzamide) were prepared as 20% solutions in absolute ethanol and evaluated for repellency against many mosquito species in Thailand under laboratory and field conditions using human subjects. In the laboratory, 0.1 ml was applied per 30-cm2 of exposed area on a volunteer’s forearm (0.66-0.67 m...

  The main purpose of this study is to estimate the maritime transportation elasticities of the environmental pollution and economic growth in Iran within the short-run and long-run to find out the relationships among maritime transportation, environmental pollution and economic growth. The lagged endogenous model (a dynamic log-linear model that we used) is estimated using two distinctive ...

1. introduction one of the most important conditions to have dusty weather beside of unstable weather is existence or non-existence of humidity. unstable weather having enough humidity will produce rain and thunder storm, else if the result will be dust storm. number of particles of dusty storm is depended to wind speed, sec of soil and its dimension. furthermore, vegetation type has importance...

This paper considers a time dependent(the travel time is not constant throughout the day) pollution routing problem (TDPRP), which aids the decision makers in minimizing travel time, toll cost and emitted pollution cost.  In complexity of urban areas most of the time one point is accessible from another with more than one edge. In contrast to previous TDPRP models, which are designed with only ...

Emissions resulted from transportation activities may lead to dangerous effects on the whole environment and human health. According to sustainability principles, in recent years researchers attempt to consider the environmental burden of logistics activities in traditional logistics problems such as vehicle routing problems (VRPs). The pollution-routing problem (PRP) is an extension of the VRP...

Air pollution is one of the major threats to environment in the present time. Increase in degree of urbanization is a major cause of this air pollution. Due to urbanization, vehicular activities are continuously increasing at a tremendous rate. Mobile or vehicular pollution is predominantly degrading the air quality worldwide. Thus, air quality management is necessary for dealing with this seve...

The magnitude of the short/medium-term air pollution exposure on atopic dermatitis (AD) flare has not been fully investigated. aim study is to investigate association airborne AD flares in patients treated with dupilumab. This an observational case-crossover study. Patients moderate-to-severe under treatment dupilumab were included. interest was mean concentrations coarse and fine particulate m...

introduction: ischemia/reperfusion (ir) injury involves a complex interrelated sequence of events. high levels of nitric oxide (no) are generated with inducible form of nitric oxide synthase (inos) leading to the renal ir injury and glutathione (gsh) depletion. the present study was designed to investigate the effect of l-nil (n6- (1-iminoethyl)-l- lysine.hydrochloride), a selective inhibitor o...

a study of substantial anthropogenic related pollution in the coastal samut prakarn province (thailand) was carried out focusing on the bang pu nature reserve (remnant mangrove wetland) using a remote sensing (geospatial) technique. statistical regression models were developed between biochemical parameters of sample point and related reflectance data obtained from satellite imagery (landsat tm...
