Genetic Diversity in Population of Fusarium Solani From Cumin in Iran
Abbas Mohammadi, Nasrin Nooras Mofrad
Journal of Plant Protection Research , 2009, DOI: 10.2478/v10045-009-0045-x
Abstract: Nineteen isolates of Fusarium solani were recovered from crown and root rotted parts of cumin plants collected from the major cumin producing area in Iran during 1999-2000 using Nash-Snyder media. One hundred and fifty eight nit mutants of F. solani were generated using PDA amended with 3% and 5% potassium chlorate. Of the nit mutants generated, 47/7%, 26/6% and 25/9% were nit1, nit3 and nitM, respectively. Nit mutants were used to force heterokaryon formation to determine VCGs and their relation to pathogenecity and geographic origin. Fifteen VCGs were determined for F. solani isolates, that 12 were single members VCGs. There was no specific relation between VCGs and geographic origin in F. solani isolates. This is the first research on the genetic diversity of F. solani from cumin.

Pakistan Journal of Biological Sciences , 2008,
Abstract: Phytophthora root and stem rot of soybean is a destructive disease of soybean in Iran. Races 1 and 3 of pathogen have already been reported from two major growing regions of the crop, Lorestan and Golestan provinces. In a survey during 2004-2005, 142 isolates of P. sojae were recovered from infected plants and naturally infested soil samples using selective media and soybean leaf baiting technique. The majority of tested isolates (110 isolates) belonged to race one of P. sojae and 32 isolates belonged to race 3. ITS region of 23 isolates were amplified with specific primers Ps1 and Ps2. Sequences of this regions were similar to other gene banks sequences except two isolates from China. This survey showed low diversity in Iranian population of P. sojae.

Open Journal of Soil Science (OJSS) , 2016, DOI: 10.4236/ojss.2016.610016
Abstract: Coastal soils of Bangladesh are affected by salinity. This study investigated salinity as a stress factor on coastal soils in Bangladesh. It was also observed if incorporation of rice straw could remediate negative impacts of soil salinity (if any) on microbial activ-ity. The microbial biomass carbon ranged from 137.85 to 614.88 μg/g among the soils (n = 11). Microbial biomass carbon content and number of both cultivable bacteria and fungi decreased in the soils with higher ECes (electrical conductivity). Respiration was measured over 30 days with each soil pre incubated at 50% of water holding capacity. Basal respiration rate as well as soil organic carbon content (r = 0.88, p < 0.05) increased with increasing ECe of soils. The cumulative basal soil respiration was higher in the soils with higher salinity (4.81 - 37.73 mS/cm) (12.91 - 16.89 mg CO2/g dry soil) than in the nonsaline soils (0.98 - 2.33 mS/cm) (5.79 - 6.51 mg CO2/g dry soil). Application of rice straw at 0.50%, 1.00%, 1.50% and 2.00% reduced the negative impact of soil salinity especially at higher ECes (6.63 - 37.73 mS/cm). Application of 1.00% rice straw appeared to be acceptable for successful amelioration of saline soils of the study area.

It is a conservative method for treatment of esthetic and functional problems in anterior region of oral cavity. Wide range of dental ceramics is now available on market for fabrication of laminate veneers. Clinician should have enough knowledge regarding the composition and properties of these materials in order to be able to choose the appropriate one according to clinical situations.
Hospital Information System and its Role in the Development of Medical and Health Services: A Review Article
Hosein Vakili Mofrad
Pajouhan Scientific Journal , 2012,
Abstract: Increasing growth of communication industries and informatics, cause the world is facing with a new revolution. Revolution of information and communication technologies in all sectors of the economy, society, politic and security of countries has left a significant effect. One of the most important application areas of information technology is the field of health and treatment. Hospital information system is the first and most important system of health care delivery. Hospital information systems are the computer systems that are easy to manage medicine and hospital management information and are designed to improve health care. Investigations have shown that using a hospital information system caused to improve quality of health care and increase satisfaction of clients. Some problems of the health care system are distribution of patients’ information and Lack of access to their records, Weak cooperation between physicians and health care workers, and also weakness of access to necessary medical information. These problems are solvable through the development of information technology and especially hospital (Health) information systems. This paper studies the hospital information systems, implementation of these systems and their role in the development of medical and health services.
The Relationships Between GDP, Export and Investment: Case Study Iran
Mahmoud Abolpour Mofrad
Business Intelligence Journal , 2012,
Abstract: This study compared the long-term and short-term relationship between GDP, export and investment during the years 1991-2008. Results show there exist a positive and significant long term relationship between investment and export with gross domestic production at 95% confidence level. But the relationship of investment and export is negative. Analysis of the vector error correction model for GDP indicates an error correction coefficient is negative which due to the high value of the GDP in the short run than long-term equilibrium value. In the short term, impact of investment and exports on GDP are positive. Effect of domestic production on investment is positive, but on export is negative.

Social Networking (SN) , 2017, DOI: 10.4236/sn.2017.62012
Abstract: Introduction: This research is a descriptive and correlational research which has been done with the purpose of surveying the relationship between mental disorders and the amount of time that people spend on Facebook. 147 members out of Facebook active users were chosen randomly. Then epidemiology questionnaire of mental disorders (SCL-90-R) was used to collect data. Data analysis was done using Spearman correlation coefficient and multiple regression. The results showed that there was a significant relation between characters such as aggression, obsession, psychosis, paranoia, depression and using Facebook (p < 0.05), but this relation was not significant in anxiety, interpersonal sensitivity, physical complaints and phobia. Furthermore, this relationship was significant regarding to subjects’ gender and marital status (p < 0.05), but there was no relationship regarding to their age.

NASRIN BANU
Indian Streams Research Journal , 2013,
Abstract: Fishing is one of the oldest means of livelihood of mankind and fisheries sectors play an important role in the national economy and in the socio-economic development of in India. West Bengal is one of the leading fish producing states in the country and the largest producer of fish seeds in the country. Fishery-related livelihoods are complex, dynamic and adaptive. A livelihood comprises the assets (natural, physical, human, financial and social capital), the activities and the access to these (mediated by institutions and social relations) that together determine the living gained by the individual or households. This paper is an attempt to focus on fisheries livelihoods in West Bengal. This study is based on secondary sources of data. The results show that fisheries livelihoods are more popular in southern districts in the state and it is less popular in the northern part of the states.
