Also effect of air on photoneutron spectrum was negligible. The calculation of photoneutron spectrum with concrete walls show that the component of fast neutrons is decreased and thermal neutrons are increased due to the room-return. In this case, with increasing distance from isocenter, fast neutrons are decreased and thermal neutrons are increased. As the field size is increased from 5×5 to 15×15 cm2, the neutron flux is increased clearly in isocenter. The neutrons flux are decreased near the door due to maze effect.

The highest MIC value was observed against S.pneumoniae, Hafnia alvei, S. saprophyticus.}, keywords = {Silver nanoparticles,Human pathogens,Rosmarinus Officinalis}, url = {https://www.ijabbr.com/article_19147.html}, eprint = {https://www.ijabbr.com/article_19147_c685521135de9062a2709708155bb0b9.pdf} } @article { author = {Raoofi, Mohammad and Alebrahim, Mohammad Taghi and Baghestani, Mohammad Ali and Khanjani, Mohammad}, title = {The effect of different harvest times of first cutting in perennial alfalfa on percentage of dry weight of weeds and alfalfa in second cutting}, journal = {International Journal of Advanced Biological and Biomedical Research}, volume = {4}, number = {1}, pages = {112-116}, year = {2016}, publisher = {Sami Publishing Company}, issn = {2383-2762}, eissn = {2322-4827}, doi = {10.26655/ijabbr.2016.2.16}, abstract = {This study was conducted in perennial alfalfa farm infected by weeds located at Km 7 Hamadan-Tehran road in the spring of 2014 and 2015 in a randomized complete block design with 11 treatments and 4 replications compared with control to investigate the effects of different harvest times of first cutting on the increase or decrease in percentage of dry weight of weeds and also alfalfa in second cutting. Treatments of this research were different harvest times in different stages of flowering in terms of percentage including: first harvesting in 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% and 50% of flowering in Alfalfa farm. In both years, the treatments were performed only in the first cutting and their effects were evaluated on the first and second cutting. In the second cutting the harvest time took place in 50% of flowering. Sampling was performed to determine the dry weight of alfalfa and also density and dry weight of weeds. The results showed that when the weed infestation is high in established alfalfa farm, early harvest in the first harvesting can significantly reduce the percentage of weeds and also the positive effects of it can be observed in second harvesting, as if early harvest increased the percentage of dry weight of alfalfa and a wide range of weeds was controlled. The final results showed that alfalfa harvesting in lower percentages of flowering led to better control of weeds.}, keywords = {Alfalfa,Weeds,Harvest time}, url = {https://www.ijabbr.com/article_19148.html}, eprint = {https://www.ijabbr.com/article_19148_83a6ca6bad256e959b3dda9570b37220.pdf} } @article { author = {Rasteh, Mousa Reza and Dastar, Behroz and Shams Shargh, Mahmoud and Zerehdaran, Saeid and Ashayerizadeh, Omid}, title = {Effect of Different Levels of Germinated Barley on Performance and Egg Quality in Laying Hen}, journal = {International Journal of Advanced Biological and Biomedical Research}, volume = {4}, number = {1}, pages = {117-125}, year = {2016}, publisher = {Sami Publishing Company}, issn = {2383-2762}, eissn = {2322-4827}, doi = {10.26655/ijabbr.2016.2.17}, abstract = {Objective: The experiment was conducted to evaluate the effect of different levels of germinated barley on performance and egg quality in laying hen. Methods: One hundred and twenty laying hens, 44-weeks old, Lohmann LSL hens were used in this experiment. Birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). The experiment was conducted as a randomized complete block design. Six experimental diets were used, diets that contained: corn-soybean meal, barley, barley plus enzyme supplementation (safizym: β-glucanases, Xylanases and Celluloses) and germinated barley replaced barley at 33, 66 and 100 percent. Experimental period was 10 weeks. The performance of laying hens measured weekly, but biweekly for egg quality. Results: The results of experiments indicated, by increasing of germinated barley in diets of laying hens feed convention ratio egg production and egg mass production significantly improved as compared to barley treatment (P}, keywords = {Germinate barley,Performance,Egg quality,Laying hen}, url = {https://www.ijabbr.com/article_26838.html}, eprint = {https://www.ijabbr.com/article_26838_946dd1411a96034abd96206f64d2e1c1.pdf} }
