Factors influencing food consumption dagger Bahrain
The food consumption pattern of Bahraini households is affected by many factors. Industrialization led to a decline in the agricultural and fishing products with the result of more dependence on imported foods. Income and prices of foods limited the purchasing power of the households, particularly low social classes. The high population growth and family size affect the quantity of food consumed by different household members. Educational level of housewife and husband has also a potent effect on the food consumption pattern. Immigrants have their influence too. They introduced many dishes which have become popular in the Bahraini community. Television advertising of food products and utensils also plays an important role in modifying the food consumption of Bahraini households. This paper discusses some of the factors influencing food consumption in Bahrain.
Correlation between family and infant food habits by scalogram analysis
370 randomly selected families from an urban and a rural communities located in an industrializing area of Northern Mexico were studied. The foods consumed by the family the day before the interview as well as indicators of education, occupation and economical level of the family were determined. Type and sequence of foods introduced to the infant's diet were also investigated in 199 cases. Guttman scales for the family diet and the infant diet at six months of age were found with coefficients of scalability of 0.80 and 0.78 respectively. A significant correlation between both scales was found (p ∼ less than 0.01) suggesting that the infant at six months participates in some extent in the family diet. Higher correlations were found between both scales and indicators of economic position of the family than with the educational level of both parents. It is suggested that in areas with some industrial progress, the economy becomes an important limiting factor in determining the dietary habits of the family a...
Laminar heat or mass transfer in rectangular channels and in cylindrical tubes for fully developed flow: comparison of solutions obtained for various boundary conditions
Abstract A comparison is made of results obtained with various boundary conditions at the wall of the channels. By comparing blood Sherwood numbers for finite wall resistance with those for constant concentration boundary condition only a small variation is found for various points along the blood channel.
