wide range of products is available; from inorganic, sodium selenite or selenate coated or not, even nanoparticles to organic forms such as selenized yeasts, chelates of selenium methionine (SeMet), pure forms of SeMet or hydroxy-selenomethionine, and some complexes sources of Se based on mixing mineral Se with glycinates, proteinates, etc. It has been confirmed that, comparing with mineral sel...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
The potential of Jiroft region has resulted in progressive development of greenhouse culture. In sustainable agricultural systems, organic manures have special role in increasing yield and soil fertility. To investigate the quantitative and qualitative responses of greenhouse cucumber to sources and levels of organic manures and their effect on some soil properties in Jiroft region, a factorial...
abstract efficient use and management of organic matter are important aspects of sustainable agricultural. organic matter is relatively low in majority of soils in iran, and continuous use of n fertilizer would create environmental hazards. therefore, the combined use of n fertilizer and organic wastes is an effective strategy. the purpose of this study was investigating of residual effects of ...
Abstract Since the onset of 1990s, development single-molecule spectroscopy has led to discovery various quantum optical signatures in organic single molecules. The single-photon nature an chromophore is particular importance because its potential as a nonclassical photon source at room temperature for information science and computing. This condensed review focuses on introduction fundamental ...
The trace elements such as selenium can be included in the diet from a variety of sources. The purpose of this study was to investigate the effects of incorporation of inorganic, organic and nano selenium in the diets of dairy calves on their performance, health, growth factor and some of their blood parameters. Forty-eight newborn Holstein calves were used in a completely randomized design ove...
Three experiments wereconducted to evaluate chemical characteristics, intestinal absorption and bioavailability of manganese(Mn)from organic, inorganic and nano sources of Mn. In experiment 1, inorganic sources of Mn including Mn-sulphate and Mn-oxide, organic sources of Mn as Mn-glycinate and Mn-bioplex and FRA® easy dry Mn as a nano source of Mn were subjected to elemental analysis and solubi...
