BACKGROUND Air pollution and weather are just two of many environmental factors contributing to traffic accidents (RTA). OBJECTIVES This study assessed the effects of these factors on traffic accidents and related mortalities in Ahvaz, Iran. METHODS In this ecological study, data about RTA, traffic-related mortalities, air pollution (including NO, CO, NO2, NOx PM10, SO2, and O3 rates) and c...

The use of proteins and peptides as human therapeutics has been increased in recent years. Lipase is a relatively homogeneous proteinaceous enzyme indicated in maldigestion. The purpose of the present study was to evaluate the effect of humidity along with compactional pressure on the enzymatic activity of wheat germ lipase. Samples of lipase powder were kept at different relative humidity (RH)...

Alternaria and Cladosporium spores belong to the most frequent and allergenic particles in bioaerosol in the temperate climate. The investigation of Alternaria and Cladosporium spore concentrations was performed in two cities in Poland, Szczecin and Cracow, in 2004-2013. The meteorological parameters taken to assess their impact on fungal spores were average, maximum and minimum temperature, re...

The aim of this study was to determine the independent effects of climatic factors: rainfall, temperature and relative humidity, on the occurrence of dengue hemorrhagic fever (DHF) in Thailand after adjustment for cyclical pattern. Data regarding monthly DHF reported cases by province, monthly rainfall, rain-days, average daily maximum temperature, average daily minimum temperature and average ...

Bio-nanocomposite films based on sago starch containing 2% cinnamon essential oil and 3% titanium dioxide nanoparticles were used in the packaging of fresh pistachios and stored at different temperatures (4, 25, and 35 ˚C) and relative humidity (30, 50, and 70%) for 20 days, and pistachio properties were evaluated in five-day intervals. Using these films in packaging improved the physicochemica...

We describe the environment effects on the amount and quality of resources collected by Melipona rufi ventris Lepeletier in the Atlantic Forest at Ubatuba city, São Paulo state, Brazil (44o 48’W, 23o 22’S). Bees carrying pollen and/or nectar were captured at nest entrances during 5 min every hour, from sunrise to sunset, once a month. Pollen loads were counted and saved for acetolysis. Nectar w...

Climate can affect the geographic and seasonal patterns of vector-borne disease incidence such as West Nile Virus (WNV) infections. We explore the association between climatic factors and the occurrence of West Nile fever (WNF) or West Nile neuro-invasive disease (WNND) in humans in Northern Greece over the years 2010-2014. Time series over a period of 30 years (1979-2008) of climatic data of a...

The filamentous phage fd was studied by both contact- and tapping-mode atomic force microscopy under conditions of controlled variations in relative humidity and changes in the applied tip force. By spin-coating freshly cleaved mica with phage containing solutions having very low salt content followed by rapid humidity control, stable and reliable sample preparation was achieved. The apparent h...

The relative humidity at the surface of a soil is calculated as a function of time from a realistic, exactly solvable model for unsaturated fluid flow. When the evaporation rate is constant, as in the atmosphere-controlled phase, the surface relative humidity suddenly drops at a particular time, even though the humidity–time function is differentiable. This sudden transition still occurs, but i...
