We present a model of disease transmission on a regular and small world network and compare different control options.Comparison is based on a total cost of epidemic, including cost of palliative treatment of ill individuals and preventive costaimed at vaccination or culling of susceptible individuals. Disease is characterized by pre-symptomatic phase, which makesdetection and contr...
We introduce new design method for 3D isotropic transformation optics device using smart transformation optics. In 2 dimension smart transformation optics, elastic deformation satisfied quasi-conformal transformation with negative Poisson’s ratio -1. We extended smart transformation optics to 3 dimension and demonstrated 3D isotropic metamaterials waveguide. This 3D waveguide is arbitrary benda...
We have previously shown in separate studies thatMDM2 knockdown via antisense MDM2 (AS-MDM2) andE2F1 overexpression via adenoviral-mediated E2F1(Ad-E2F1) sensitized prostate cancer cells to radiation.Because E2F1 and MDM2 affect apoptosis through bothcommon and independent pathways, we hypothesizedthat coupling these two treatments would result inincreased killin...
Bright and short x-ray flashes extracted from a synchrotron allow the study of the structuraldynamics of proteins at medium resolution (~ 10 Ang) with 100ps time resolution. Heme-basedproteins, due to their natural light sensitivity and robustness, are particularly suited for such studies.In this contribution I will discuss the basic components of the experiment apparatus and th...
Morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (LAB), isolated from traditional yoghurts produced by tribes of Iran. From 60 yoghurt samples, a total of 137 LAB isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. Biochemical tests showed the occurrence of 9.76% mesophilic ho...
Microbial lipase is one of the major sources enzyme that has been broadly exploited in food, detergent, and pharmaceutical industries due to its high catalytic activity, yield, environmental friendliness cost-effectiveness. Therefore, aim this study was optimize medium for submerged fermentation production by a novel strain, Bacillus salmalaya strain 139SI. The media subjected Luria Bertani (LB...
abstract: acidophilus milk after preparation, with the defined characteristics of ph, titratable acidity and viable counts of lb. acidophilus, was kept at the refrigerator (5 °c) and changes of above mentioned parameters were evaluated during 21 days at 7-day intervals. the obtained results showed that the titratable acidity of product significantly (p≤0.05) increased over storage period, demon...
An isolated strain (from rice), Bacillus acidocaldarius was able to produce extracellular α-amylase.The enzyme was partially purified with 50% acetone and showed 4.3-fold purification. Amylase was immobilized on different carriers by different methods and its specific activity for starch hydrolysis studied. Immobilized α -amylase on glass beads (covalent binding) and cation exchange resin (ioni...
This study explores the predictive power of lifestyle orientations, reliance on traditional news media, attributes of online news, traditional mass media use, and demographics on online news adoption and likelihood to adopt. Data were gathered using a snowballing method from 453 information workers and university students, of which 52% were frequent online newsreaders and 48% non-users. Explora...
