Improvements in micronutrient content or bioavailability of staples can impact diet. We aimed to assess variability of rice zinc at field, household, and village levels, and its association with dietary zinc and nutritional status of children. Rice samples were collected from

Carbon dioxide is the major greenhouse gas responsible for global warming. Man-made CO2 emissions contribute approximately 63% of greenhouse gases and the cement industry is responsible for approximately 5% of CO2 emissions emitting nearly 900 kg of CO2 per 1000 kg of cement. CO2 from a cement plant was captured and purified to 98% using the monoethanolamine (MEA) based absorption process. The capture cost was $51 per tonne of CO2 captured, representing approximately 90% of total cost. Steam was the main operating cost representing 39% of the total capture cost. Switching from coal to natural gas reduces CO2 emissions by about 18%. At normal load, about 36 MW of waste heat is available for recovery to satisfy the parasitic heat requirements of MEA process; however, it is very difficult to recover.

In 1985–86 a food consumption survey covering about 4000 people was carried out in 11 locations of Dhaka city. Comparison of the results with those of the 1962–64 study revealed a deteriorating food and nutrition situation of the urban population. Among food groups, consumption of pulses and food from animal sources in particular have greatly declined. Among nutrients the foremost deficiency was of energy in which 68% of families consumed less than the requirement. A similar percentage of families consumed inadequate protein, but in 23% of them there would not have been a protein problem had there been an adequate supply of other sources of food energy. Among the micronutrients the severest deficiencies were of riboflavin and vitamin A. Forty two percent of families consumed less than the recommended level of ascorbic acid. A comparison of intake patterns in urban and rural areas shows several differences, even though the pattern of intake of dietary consituents was similar.

The influence of seasonal variations in dietary intakes and nutritional status was examined in two rural villages of Bangladesh covering a population of 600. The results suggest considerable seasonal variations in intakes and prevalence of malnutrition depending on agricultural productivity. Intakes of almost all food was found to be the lowest in late October‐early November and May‐June period, the months preceding the two major rice (aman and aus) harvests. A higher incidence of malnutrition was accordingly seen during these periods. Alternative strategies in food production and availability seem to be needed to eliminate the severe consequences of malnutrition and to assist in alleviating rural poverty.

In 1981–82 a nationwide food consumption survey covering 4000 people was carried out in 12 statistically selected rural locations of Bangladesh. Comparison of the results with those of the 1975–76 and 1962–64 studies revealed an alarming food and nutrition situation in the country. Intakes of almost all foods and nutrients had decreased. Consumption of pulses and food from animal sources in particular had seriously declined. The foremost deficiency was of energy in which 76% of families consumed less than the requirement. Seventy‐seven percent of families consumed inadequate protein, but in 25% there would not have been a protein problem had there been an adequate supply of nonprotein sources of energy. Of the micronutrients the severest deficiencies were riboflavin and retinol. Eighty‐seven percent of families consumed less than the recommended level of ascorbic acid.
