Selenium (Se) is an essential element for the human body. Humans meet their basic Se requirements primarily through food consumption. The largest Se-rich contiguous area in China located southeast of Guangxi. In this study, accumulation and translocation Guangxi rice–soil system was assessed. Organically bound (O-Se) found to be main type soil (72.5%), had a good linear relationship with total ...

background: several influential factors such as transcription factors and intracellular signaling components are involved in differentiation of stem cells into a specific lineage. p15 and p16 proteins are among these factors. accumulating evidences has introduced the epigenetic as a master regulator of these factors during lineage specification. the main objective of this study is to determine ...

Abstract
 Bintaro is a plant that contains poison in all parts of the plant. Cardiac glycoside compounds contained plants can be used as biopesticides to repel rats. Rat pests are one important rice difficult control, so production always decreases. Therefore it necessary look for an effective, efficient and environmentally friendly control technology, namely by using extracts which able b...

Let S(r) denote the w-sphere with a linear involution having a fixed point set of codimension r, where O ^ r ^ w . We pick some fixed point as a base point and consider the set [S(r); S(t)] of base point preserving equivariant homotopy classes of maps from S(r) to S(t). This has a natural group structure for n—r^l and is abelian if n—r^2. There is a suspension functor S without action and one 2...

The discovery of stem cells in adult nerve tissue makes the repair of brain damage a realistic possibility.

Poor N use efficiency by rice (Oryza sativa L.) in many regions of the world is due to the intensity of loss mechanisms functioning in the system. A study was conducted to determine the maximum potential loss of fertilizer "N in a Crowley (Typic Albaqualfs) silt loam soil where conditions are favorable for both nitrification and denitrification in the root zone of rice. Nitrogen losses were mea...

Nitrogen fertilizer application rates in intensive agricultural systems have increased dramatically in recent years, especially in protected vegetable production systems. This excessive use of nitrogen fertilizer has resulted in soil secondary salinity, which has become a significant environmental stress for crops such as cucumber, in the protected farmlands. It is thus necessary to illuminate ...
