Lake Pavin is a deep meromictic lake. Its water column is divided into two parts: the mixolimnion, which is subjected to mixing during seasonal overturns; and the monimolimnion which remains unmixed. Using high precision and high frequency temperature and conductivity profiles along with continuous temperature measurements, this study reveals the presence of a sublacustrine, intermittent cold s...

BACKGROUND There is growing evidence that living conditions at birth play a role in medical conditions later in life. Population-based studies from the Northern Hemisphere have shown that persons born in the spring or summer are at greater risk of committing suicide. A statistical correlation with light availability at birth has been observed in past research, but the cause remains unknown. Gre...

BACKGROUND Light therapy is a known treatment for patients with seasonal affective disorder. However, the efficacy of light therapy in treating patients with non-seasonal depression remains inconclusive. AIMS To provide the current state of evidence for efficacy of light therapy in non-seasonal depressive disorders. METHOD Systematic review of randomised controlled trials (RCTs) was conduct...

In spite of the efforts of the World Health Organization (WHO), influenza continues to be a major public health problem, both because of its impact on the health of subjects at risk, such as the elderly, and because of the economic burden that it places on society. Adjuvants are agents which, when incorporated into vaccines, enhance the immunogenicity of their antigens. The need for ever more i...

seasonal variation of fatty acids composition of milk and various milk products have been subjected to many investigations.however ,most of the researches are concerned with a single product and apparantly there is no inforation about the extent and the factors which contribute to changes in fatty acids composition of lipids in the process of ghee-making by the  traditional methods.thus compara...

In pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. Basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...

having a comprehensive and correct understanding of grazing behaviour of livestock helps to maximize livestock products. moreover, a good understanding of livestock behavior allows us to predict the effects of livestock on rangeland and finally we can do livestock grazing management the best possible. recognition of grazing behavior of animals can provide solutions enables the optimal use of ra...

Seasonal Allergies in a Changing Climate Several intertwined factors influence how a plant grows and how much pollen it produces. Projected rises in two of these—regional temperatures and atmospheric CO 2 levels—could mean an increase in the number of people affected by seasonal allergies.

While negative effects of human disturbance on animals living above the ground have been widely reported, few studies have considered effects on animals occupying cavities or burrows underground. It is generally assumed that, in the absence of direct visual contact, such species are less vulnerable to disturbance. Seabird colonies can support large populations of burrow- and cavity-nesting spec...

The study was undertaken to investigate the year-to-year and seasonal variations in stunting among preschool children living at subsistence level in rural Ethiopia. Five thousand five hundred and eight anthropometric measurements were taken in 678 children (324 boys and 354 girls). The study classified 11.4% and 54.4% of the measurements as wasted and stunted respectively. Stunting occurred mor...
