background: decay products of radon and thoron present in indoor environment are the most important sources of radiation from natural sources which affect human beings, since general public spend at lest 80% of their time in indoor. materials and methods: air samples were collected for measuring the concentration of radon and thoron daughter products from various indoor environments during four...

in this study, we present changes of peroxidase (e. c. 1.11.1. 7) activities in the root of brassica napus var. okapi during rosette stage until ripening of the fruits. peroxidase activity was determined seasonally over an eight month period. results showed that total peroxidase activity in the root was highest in mid june and the lowest activities were observed from time of winter dormancy unt...

In the wild, the pig adapts her reproductive functions according to the seasonal changes in the environment, such as the ambient temperature and availability of food. Like in other short day seasonal breeders, breeding season is favoured in the mid winter in order to provide the offspring with the best chances to survive four months later. Seasonal changes in environment are perceived mainly by...

[1] We carried out a systematic study of the seasonal cycle and its latitudinal variation in the nitrous oxide (N2O) data collected by National Oceanic and Atmospheric Administration–Global Monitoring Division (NOAA-GMD) and the Advanced Global Atmospheric Gases Experiment (AGAGE). In order to confirm the weak seasonal signal in the observations, we applied the multitaper method for the spectru...

backgrownd: studies in regions with seasonal climatic variations have revealed a correlation between human natural conception and birth rates. holidays and other cultural activities probably have influence on conception, but the ambient temperature and emotional influences on the female hormones related to fertility may play an important part in the seasonal variation in conception. objectives:...

Seasonal fluctuations in food availability show a tight association with seasonal variations in body weight and food intake. Seasonal variations in food intake, energy storage, and expenditure appear to be a widespread phenomenon suggesting they may have evolved in anticipation for changing environmental demands. These cycles appear to be driven by changes in external daylength acting on neuroe...
