Meiotic crossover (CO) recombination facilitates evolution and accurate chromosome segregation. CO distribution is tightly regulated: homolog pairs receive at least one CO, CO spacing is nonrandom, and COs occur preferentially in short genomic intervals called hotspots. We show that CO number and distribution are controlled on a chromosome-wide basis at the level of DNA double-strand break (DSB...

Co-simulation is an approach where the simulation of both transmission and distribution system gets combined. This provides more accurate description results which can help decision making operator. Due to increasing rate decentralization, there bidirectional energy flow. Thus, getting uninterrupted power supply even under any kind stressed situation possible with renewable sources (RES), distr...

in this study the characteristics of two different kinds of la0.6sr0.4co0.2fe0.8o3 (lscf) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from fuel cell materials co. (fcm co., usa), were compared. the co-precipitated powder was prepared by using ammonium carbonate as precipitant with a nh4+/no3- molar ratio of 2 and calcination at 1000c for 1 h....

Dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for RESS (Rapid Expansion of Supercritical Solution) process. Supercritical CO2 was used as solvent and Ibuprofen was applied as the model component in all runs. The resulting Ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by SEM and laser diffraction pa...

Lotka’s Law originally calculated only the frequencies of single or first authors. However, given the growth and popularity of scientific collaboration, the distribution of co-author pairs’ frequencies should also be considered. Based on the previous researchers’ results, this article will demonstrate that the distribution of co-author pairs’ frequencies can be reflected by a social gestalt and...

20 soil samples collected from the vicinity of the Khash Cement plant, Iran, were analyzed for As, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb and Zn using ICP-OES. The results revealed that the metal distribution were in a fluctuating manner considering various distances and direction from the cement facility. However, it was observed that the mean concentration of the soil samples has no special trend wit...
