Processed foods are an integral part of American diets, but a comparison of the nutrient contribution of foods by level of processing with the recommendations of the Dietary Guidelines for Americans regarding nutrients to encourage or to reduce has not been documented. The mean reported daily dietary intakes of these nutrients and other components were examined among 25,351 participants ≥2 y of...
The effect of pastoral management on the standing crop biomass of large ungulates, an index of carrying capacity, is analysed at a regional level by using data compiled from published sources covering east and south Africa. The effect of primary production is controlled for by using two environmental factors, rainfall and soil nutrient availability, and the effect of species richness of the ung...
Effects of supplementary nutrient in the production of red tilapia (Oreochromis sp) and Lettuce (Lactuca sativa var longifolia) evaluated in a representative water recirculating aquaculture system. The nutrient solution supplemented was 25% level of (L25) nutrient solution as medium used for aquaponic production of lettuce in the NFT system (based on cooper’s formula). Thus, a completely random...
بررسی تأثیر شکل های مختلف نیتروژن و pH محیط ریشه بر رشد گراس Brachiaria brizantha در کشت هایدروپونیک
This study was conducted to evaluate plant response of Brachiaria brizantha cv. MG5 to nitrogen (N) forms and different pH's of nutrient solution. In this study, under controlled conditions in growth chamber with hydroponics culture, seedlings after germination were treated with different N forms as nitrate, ammonium, and ammonium nitrate, as well as with different nutrient solution pH's. A sol...

Previous studies have demonstrated that populations differ from each other in size and proportion, and that these differences can affect metric assessment of sex. This paper establishes standards for determining sex from fragmentary and complete tibiae in the modern Croatian population. Measurements were taken on 180 tibiae (109 male and 71 female) from positively identified victims of the 1991...

boron toxicity usually occurs in arid and saline soils. among all the pollutant'sresource, irrigation water is the most important factor in boron elevating in the soil.modification of boron-rich soils is difficult and in this case, resistant varieties can playan important role in increasing the cultivation in areas with high boron level. to assessthe effects of different concentrations of ...
