to study the seasonal variation in the characteristics of the azarbaijani buffalo semen, three 2-4-year-oldbulls of azarbaijani water buffaloes, kept in the buffalo breeding center, in urmia, northwest of iran, wereselected. semen samples were collected once a week for a period of one year using artificial vagina and abuffalo cow as a dummy. semen volume, colour, ph and motility and spermatozoa...

Milk fat exhibits seasonal variations in composition and properties which are undesirable for many subsequent applications. Thus techniques are sought to process dairy products in order to achieve a consistent quality. A brief introduction to milk fat presents its most important particularities, especially composition, seasonal variations, solid fat content, crystallisation and polymorphism. Th...

The climatological seasonal cycle of sea surface temperature (SST) in the tropical Pacific is simulated using a newly developed upper ocean model. The roles of vertical mixing, solar radiation, and wind stress are investigated in a hierarchy of numerical experiments with various combinations of vertical mixing algorithms and surface-forcing products. It is found that the large SST annual cycle ...

The Georgia Institute of Technology–Goddard Global Ozone Chemistry Aerosol Radiation and Transport (GOCART) model is used to simulate the aerosol optical thickness t for major types of tropospheric aerosols including sulfate, dust, organic carbon (OC), black carbon (BC), and sea salt. The GOCART model uses a dust emission algorithm that quantifies the dust source as a function of the degree of ...

BACKGROUND Inadequate energy and nutrient intakes are a major nutritional problem in developing countries. A recent study in Beninese school-aged children in different seasons revealed a high prevalence of stunting and poor iron status that might be related to the food pattern. OBJECTIVE To analyse the food pattern and resulting energy and nutrient intakes of rural Beninese school-aged childr...

BACKGROUND Presumed seasonal use of acetaminophen-containing products for relief of cold/influenza ("flu") symptoms suggests that there might also be a corresponding seasonal pattern for acute liver injury (ALI), a known clinical consequence of acetaminophen overdose. OBJECTIVE The objective of this study was to determine whether there were any temporal patterns in hospitalizations for ALI th...

We assess the daily characteristics of recent past precipitation over Africa by means a large ensemble observational products, including reanalysis, gauge-based, and satellite-based products. The spatial distribution seasonal mean varies considerably amongst products especially areas where gauge networks are sparse. Large uncertainties in annual cycle visible particular Ethiopian Highlands, eas...
