Methotrexate (MIX) (2 x 1(T8 M) inhibited DMA synthesis in CCRF-CEM cells, causing cells to accumulate in early S phase while cellular RNA content and cell size continued to increase. Two-parameter flow cytometric analysis of DMA and RNA showed these cells to be unbalanced with excessive RNA relative to DNA content. Fifty % of cells remained viable after a 96-hr exposure to 2 X 10~8 M MTX. In c...

Chinese solar greenhouse (CSG) is universally applied in northern China for producing horticultural products. CSG is characterized by the unbalanced structures with an arched front roof face to the south side and a thick wall as well as back roof in the north side. Such structures affect light distribution in the greenhouse. This study aims to investigate the light distribution properties in CS...

We study a class of in...nite-horizon nonlinear dynamic economic models in which preferences, technology and laws of motion for exogenous variables can change over time either deterministically or stochastically, according to a Markov process with time-varying transition probabilities, or both. The studied models are nonstationary in the sense that the decision and value functions are time-depe...

Abstract This research has aimed to examine the feedback effects between economic growth and environmental degradation through health that is one of human capital elements and also the consequences of such these relationships on economic convergence process during the period 1990-2013 for 60 developing countries in framework of simultaneous equations model by using unbalanced panel data analysi...

Nutritional regulatory responses were compared for the cryptic 'solitarious' and the conspicuously coloured, aggregating 'gregarious' phases of the desert locust Schistocerca gregaria. The desert locust has the genetic potential to exist in either phase, changing between them within a lifetime and epigenetically across generations. Our aim was to compare final-instar nymphs of the two phases wi...
