Preprotein translocation across the outer and inner envelope membranes of chloroplasts is an energy-dependent process requiring ATP hydrolysis. Several precursor proteins analyzed so far have been found to be imported into isolated chloroplasts equally well in the dark in the presence of ATP as in the light where ATP is supplied by photophosphorylation in the chloroplasts themselves. We demonst...

There is a false notion of existing available, abundant, and long lasting fuel energy in the Gulf Cooperation Council (GCC) Countries; with continual income return from its exports. This is not true as the sustainability of this income is questionable. Energy problems started to appear, and can be intensified in coming years due to continuous growth of energy demands and consumptions. The deman...

The current trade of agricultural goods, with connections involving all continents, entails for global exchanges of "virtual" water, i.e. water used in the production process of alimentary products, but not contained within. Each trade link translates into a corresponding virtual water trade, allowing quantification of import and export fluxes of virtual water. The assessment of the virtual wat...

Utilization of combined heat and power (CHP) systems that simultaneously fulfill the electrical and heating energy needs is considered as an effective strategy for management of energy demand and consumption. Overall operational efficiency in excess of 70% is made possible, when these systems are utilized, and it is expected that needs for both the demand and supply sides are met even under ...

Based on a set of experiments, using a transversely exited (TE) oscillator-amplifier N2-laser system (OSC-AMP) with the AMP effective length of 31cm, measurements have been carried out for small signal gain, g0, and saturation energy density, Es, for different AMP gap separations. It was found that the gain-value depends on the AMP electrode gap separation, d<su...

Background: The assessment of RBE quantity in the treatment of cancer tumors with proton beams in treatment planning systems (TPS) is of high significance. Given the significance of the issue and the studies conducted in the literature, this quantity is fixed and is taken as equal to 1.1.Objective: The main objective of this study was to assess RBE quantity of proton beams and their variations ...

Proplastids are undifferentiated plastids of meristematic tissues that synthesize amino acids for protein synthesis, fatty acids for membrane lipid production, and purines and pyrimidines for DNA and RNA synthesis. Unlike chloroplasts, proplastids depend on supply, with reducing power, energy, and precursor metabolites from the remainder of the cell. Comparing proplastid and chloroplast envelop...
