Abstract: In the present research, for the development of Fars province minimum temperature atlas, minimum daily temperature data of 20 evaporative stations of Fars Regional Water Organization and five synoptic stations of Fars Meteorological Organization were used. At first, two starting times were selected for all of the stations. The first was the first day of Farvardin for analyzing the spring frost and the secend was the first day of Mehr for analyzing the autumn and winter frost. Also, the temperature range of 0 to –1.5 was classified as mild frost or freeze, the temperature range of -1.5 to –3 as the moderate frost or freeze and temperature below –3 as severe frost or freeze. The data of minimum temperatures, the first and the last days in which the three temperature ranges occurred and the day of the lowest temperature based on the two starting times were recorded. The selected number of days (dates) were fitted to the distribution functions by SMADA software and the best distribution function was identified using the statistical parameter Root Mean Square. The best fitted distribution functions were Pearson type III and log Pearson type III. Then, based on the fitted distribution function, the number of days for the occurrence of the first and last frost and number of days for the occurrence of the first lowest temperature were determined at 50 and 70% probability levels. Finally, each of these occurrence dates was plotted with Surfer software using the geographical positions of each station (longitude and latitude) for Fars province. Based on these plotted maps, the best days of planting and harvesting of the crops can be determined throughout the Fars province.
On the Anisotropic Big Bang Cosmology With A General Non-Linear EoS
Kh. Saaidi,S. Ziaee
Physics , 2010,
Abstract: We study the anisotropic Big Bang cosmology for a general non-linear equation of state (EoS) in standard general relativity cosmology in early times. According to brane world cosmology and loop quantum gravity which introduce a quadratic term in the energy density, we study a non-linear EoS with a general nonlinear term in the energy density. We show that this general non-linear term isotropize the universe at early times. And also, we find out this model has a phantom like behavior for special case.
Bouncing cosmology without anisotropy

Abstract: Using non-linear equation of state for pressure and density energy, we show that the universe is began with a smooth and isotropic bounce. We use a non-linear equation of state which is a binary mixture of perfect fluid and dark energy. We show that in order to preserve a smooth and isotropic bounce, the source for contraction before the bounce, must have an equation of state with $\omega>1$ (Ekpyrotic matter) and a dark energy with positive pressure.
Comparison of Pseudomonas syringae pv. syringae van Hall Isolates from Different Hosts Based on Phenotypic Characteristics, Serological Properties and Pathogenicity
S. M. Taghavi,M. Ziaee
Journal of Science and Technology of Agriculture and Natural Resources , 2003,
Abstract: In order to compare Pseudomonas syringae pv. syringae (Pss) isolates from cereals, citrus, stone fruits and weeds by phenotypic characteristics, serological properties and pathogenicity, samples were taken during 1998-1999 in Fars Province, Karaj, Fereidan, Aligudarz and Shahrekord regions. From 350 fluorescent isolates, 47 were negative with respect to oxidase, potato soft rot and arginine dihydrolase tests but positive in hypersensitive reaction (HR) on tobacco, pelargonium, or both. In complementary biochemical tests, these isolates were identified as Pss. Based on LOPAT (levan, oxidase, potato soft rot, arginine dihydrolase and HR on tobacco leaves) tests, the isolates were divided into two groups, but based on the results of GATTa tests alone, isolates were divided into nine groups. Isolates from different hosts showed differences in lipolysis, syringomycin production, ice nucleation activity, lecithinase, pathogenicity, serology and protein profiles.
Optimal Redundancy Allocation in Hierarchical Series-Parallel Systems Using Mixed Integer Programming  [PDF]
Mohsen Ziaee
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.41014

Reliability optimization plays an important role in design, operation and management of the industrial systems. System reliability can be easily enhanced by improving the reliability of unreliable components and/or by using redundant configuration with subsystems/components in parallel. Redundancy Allocation Problem (RAP) was studied in this research. A mixed integer programming model was proposed to solve the problem, which considers simultaneously two objectives under several resource constraints. The model is only for the hierarchical series-parallel systems in which the elements of any subset of subsystems or components are connected in series or parallel and constitute a larger subsystem or total system. At the end of the study, the performance of the proposed approach was evaluated by a numerical example.

Abstract: Every year, millions of Moslems depart to Saudi Arabia from more than one hundred countries around the world for paying to Hajj precept. High percentages of these pilgrims suffer from an influenza-like illness (ILI). This study was designed and conducted on 32370 Iranian pilgrims (36% of total number of Iranian pilgrims) to evaluate the incidence of the illness and determination of influenza vaccine’s efficacy to prevent it. A total of 3465 individuals, 10.7% of under studied population, had vaccinated themselves voluntarily against the influenza and the rest were not vaccinated. As a whole, 70% of the studied population suffered from ILI. In this study, the incidence of illness among those vaccinated was about 56% and among those not vaccinated about 72%; the difference was significant (P < 0.001), with odds ratio (OD) = 0.50 and (1 - OD) = 0.50; thus the efficacy of the vaccine in this study was estimated to be 50% and it was efficient in reducing the cases of ILI. We recommend administration of the influenza vaccine to Iranian pilgrims one month before departure to Saudi Arabia for Hajj pilgrimage.

Abstract: "nBackground: Annually millions of Muslims depart to Saudi Arabia for performing a religious pilgrimage called "Hajj". In this ceremony, pilgrims face numerous health hazards and injuries such as pressing in overcrowding, sliding, burning, fal-ling down, traffic accidents etc. The main purpose of this study was to determine the prevalence of injuries in Hajj period across 2004 to 2008."nMethods: This study was conducted on 253808 Iranian pilgrims on five consecutive years of Hajj ceremonies, from 2004 to 2008. We used a report sheet with 13 types of injuries and 13 mechanisms of these injuries. SPSS V13.5 soft ware was used for analyzing the data. ANOVA and independent sample t- test was conducted, and relationships were considered signifi-cant at P< 0.05."nResults: The most common injuries was "tissue contusions and ruptures "(about 76/10000), and "tendon lesions" (about 62/10000). In addition, the most common mechanism of injuries was "ankle sprain" (69/10000) during the five consecu-tive years. The prevalence of all fractures was about 49/10000 and the proportion of burning with hot water or fire was about 40/10000. Changes of all causes of the injuries were significant in this study (P< 0.05)."nConclusions: We have suggested some directions for preventing of injuries and related Injuries in Hajj, in this study.
