Cells and organisms must coordinate their metabolic activity with changes in their environment to ensure their growth only when conditions are favourable. In order to maintain cellular homoeostasis, a tight regulation between the synthesis and degradation of cellular components is essential. At the epicentre of the cellular nutrient sensing is the mechanistic target of rapamycin complex 1 (mTOR...

Fractional factorial split-plot designs are widely used when it is impractical to perform fractional experiments in a completely random order. When there too many subplots per whole plot, or few plots, with replicated settings of the plot factors preferred. However, such an important study undeveloped literature. This paper considers WP from viewpoint clear effects. We investigate sufficient an...

In some experiments, the levels of factors are difficult to change; then fractional factorial split-plot (FFSP) designs suitable for selection. an FFSP design, divided into two classes—the whole plot (WP) and subplot (SP) factors. selection WP can affect that SP factors, which attracts much attention Paying more a new optimality criterion selecting such is proposed. The robustness proposed meth...

abstract a field experiment was conducted at iranian plant protection research farm in karaj during 2009 to evaluate the effects of diffrent planting patterns, times of mechanical control and herbicides application on weeds density and biomass in sugar beet farms. the experimental design was split–split plot based on randomized complete block design (rcbd) with four replications. planting patte...

Wheat is one of the important food staff in consumption pattern of each country. More than 50 % of human energy is supplied from bread in the developing country. Combine losses is less than 2-3% in developed countries, while in developing country is about 15-20% in different regions and circumstances of harvesting seasons and field conditions. In this research project that effect of combine typ...

abstract this study was conducted to determine the impacts of different drip irrigation method and amount of water on yield and water use efficiency of tomato in varamin agricultural research center, iran. the study was done during two years. experimental design was randomized complete blocks design (rcbd) in split plot with three replications. three different drip irrigation method; surface dr...
