The paper surveyed the chemical composition and nitrogen distribution of Maiwa yak milk, and compared the results with reference composition of cow milk. Compared to cow milk, yak milk was richer in protein (especially whey protein), essential amino acids, fat, lactose and minerals (except phosphorus). The contents of some nutrients (total protein, lactose, essential amino acids and casein) wer...

Three quarters of the world’s phosphate deposits are of sedimentary origin and 75%–80% of those include carbonate gangue. In this study, carbonate sedimentary phosphate deposits of the Lar Mountains of southwest Iran are studied. These deposits consist mainly of calcite, fluorapatite, quartz, kaolinite and illite, with an average P2O5 grade of 9%–10% (low-grade). Various pre-processing and proc...

land treatment method of municipal and industrial wastewaters for utilization of nutrients in the wastes for raising useful crops and tertiary(or advanced) treatment of the water for improving stream quality or to recharge falling water tables is increasing in some parts of the world, particulary in the arid area. as emphasis in this type of treatment method and prevention of surface and underg...

The increasing requirements for the environmental protection have resulted in the search for more effective, inexpensive and ecologically safe solutions. Zeolite is one of the alternatives, which due to their peculiar structure are widely used for various environmental processes. The demand for an easily accessible and inexpensive source of zeolite has raised interest in synthesis of these mine...

Algae are a very large and diverse group of autotrophic organisms which ranges from unicellular to multicellular forms. They are primary producers which is a source of many nutrients and it has high protein content. The most complex marine forms are called seaweeds. Blue green algae ,red algae, green algae assigned higher contents of dietary fibres. Certain beverages are prepared from sea algae...

Electrostatic and/or high tension separation has been used for the separation of rare metal bearing minerals, foods, industrial wastes, and so on. Since the separation is achieved by the difference mainly in surface conductivity of materials, the efficiency in humid circumstances is very low and the applicability is considerably limited. We applied the following two-stages pretreatment techniqu...

Clay minerals have been used in medicinal applications since Aboriginal times (Carretaro, 2002; Wilson, 2003). Clay poultices are used to heal wounds; people eat clays to coat stomach linings and soothe indigestion; animals eat clay containing trace elements (e.g., As) that can kill worms. The reasons that various clay minerals are effective as medicines may be as variable as the ailment, but b...

Organic minerals have been subject of an increasing number of investigations recently. These compounds can be considered the most significant event regarding commercial forms of minerals targeting animal supplementation in the last decades. Minerals, especially metals, are usually supplemented in poultry feeds using cheap saline sources and have never required a lot of attention in terms of qua...

The New Misola consists of millet soybean, peanut, vitamins, minerals, and industrial amylase. Our objective is to demonstrate that porridge made from local grains and legumes restores the nutritional balance of malnourished children. The study was carried on 304 malnourished children aged 6-48 months including 172 girls and 132 boys from Saint Camille Medical Centre. At the beginning, these ma...
