An Investigation into Eco-tourism Potential of the Alamut Region of Iran using SWOT Analysis Model
Keivan Saeb,Razieh Jafari Hajati,Shiva Rezai
Ecologia Balkanica , 2012,
Abstract: The present research examines the potentials and limitations of tourism in the Alamut region, offering suggestions and strategies for the promotion of tourism in this region. Research methodology adopted in this study is based on analytical-descriptive approach. To formulate and establish a sound research theoretical framework as well as to review the research literature, a questionnaire tooling method was used and the results were analyzed using the SWOT technique. While introducing the tourist attraction in the province, the influential factors in the region categorized into the four headings of: strengths; weaknesses; opportunities and threats were included in our considerations and strategies or guidelines for a sustained tourism development in the region provided. The research findings, taking into consideration the present status of the Alamut region, indicate that despite the fact that the region houses a great number of ancient sites and monuments and enjoys a high level of bio-diversity resources, making it the ideal candidate to be transformed into an exemplary tourist attraction pole, it is faced with major obstacles to reach this goal. In order to remove some of the problems of the region, strategic factors were analyzed and priorities delineated. The findings indicated that a focused attention and description of the values of the region is alleviated through the holdings of seminars or meeting and conferences as well as paving the way to give cultural knowledge and understanding to prevent inflicting widespread damages to the environment; to establish hotels; to provide welfare facilities and introduce natural resources as well as historical sites and their ancient heritage.

Use of Recombinant Lines of Wheat for Study of Association Between High Molecular Weight Glutenin Subunits and Flour Quality Characteristics
Abdolmajid Rezai
Journal of Science and Technology of Agriculture and Natural Resources , 1997,
Abstract: The relation between high molecular weight glutenin subunit alleles and flour quality traits have been studied for 117 recombinant inbred lines (RILs) derived by single seed descend to F7 from a cross of Anza, a low quality cultivar, and Inia, a high quality cultivar, containing different alleles at 3 GLU-1 seed storage protein loci. RILs were classified by SDS-PAGE for the 8 possible combinations of the alleles. The allelic variation at the GLU-D1 locus accounted for most of the variation observed in SDS-sedimentation, mixing time and tolerance, and protein content. The GLU-D1 allele encoding the subunits 5+10 was superior to its allelic counterpart, encoding 2+ 12. All three loci had significant single locus additive effects for SDS-sedimentation volume and mixing tolerance. The additive effects of GLU-D1 locus on mixing time and protein content were also significant. The epistatic additive effects were mostly negative and with the exception of αAB and αAD for SDS-sedimentation volume were not significant.
Choices of health care financing schemes for resource poor country: An analysis of Nepal’s experiences  [PDF]

Health (Health) , 2013, DOI: 10.4236/health.2013.58176
Abstract:

An appropriate health care financing scheme can improve the efficient, equitable, and effective use of health care resources; however, each popular health care financing scheme has some advantages and disadvantages. The designing of health care financing strategy to fit with the country specific features is not straightforward. In resource poor country, allocation of resources for health care services are always critical and frequently unstable due to nuances annual budget process, small fiscal space, uncertainties in contributions of external development partners. Considerable quantities of country specific researches require for the choice of an appropriate health care financing scheme. The paper illustrates possible better options for the government to pursue the goal of ensuring that the poor receive more benefits. The paper compares the benefit incidences and cost of services with different options purposed for primary health care services by utilizing recently collected data from different hospitals in Nepal. The paper offers an alternative policy such as a universal free care below the district level services; but in the district level which is top level of primary care, “extended targeted free health care” may be an efficient, fair, and relatively simple approach.

A Genetic Programming-PCA Hybrid Face Recognition Algorithm  [PDF]
Behzad Bozorgtabar, Gholam Ali Rezai Rad
Journal of Signal and Information Processing (JSIP) , 2011, DOI: 10.4236/jsip.2011.23022
Abstract: Increasing demand for a fast and reliable face recognition technology has obliged researchers to try and examine different pattern recognition schemes. But until now, Genetic Programming (GP), acclaimed pattern recognition, data mining and relation discovery methodology, has been neglected in face recognition literature. This paper tries to apply GP to face recognition. First Principal Component Analysis (PCA) is used to extract features, and then GP is used to classify image groups. To further improve the results, a leveraging method is also utilized. It is shown that although GP might not be efficient in its isolated form, a leveraged GP can offer results comparable to other Face recognition solutions.
Studies of Grinding Media Corrosion from Galvanic Interaction on Galena Flotation  [PDF]
Ebrahim Allahkarami, Abdoreza Zarepoor, Bahram Rezai
International Journal of Nonferrous Metallurgy (IJNM) , 2014, DOI: 10.4236/ijnm.2012.33004
Abstract:

This study has been done to determine the galvanic interaction between five types of grinding media (mild steel, cast iron, 10% chromium, 20% chromium, and ceramic media) and galena, in situ of the mill. The ceramic media has a significantly not galvanic interaction with galena and high chromium media has a significantly weaker galvanic interaction with galena, and produces a very much lower amount of oxidize iron species in the mill discharge than mild steel medium. The investigation of the various reactions occurring on the galena surface was investigated by ethylene diamine-tetra acetic acid disodium salt (EDTA) extraction and X-ray photoelectron spectroscopy (XPS) measurements. The floatability of galena is dependent on the galvanic current between grinding media and galena during grinding because the current is relative to the amount of iron oxidation species and the reduction rate on galena. Iron oxidation species depressed galena flotation. The optimum galena flotation was achieved by selecting grinding conditions that enabled iron oxidation to be controlled.

K. Rezai,T. Farboodnia
Agricultural Journal , 2013,
Abstract: In this research the effects of 0, 25, 50, 100, 200 and 300 ppm of manganese concentration on Pisum sativum. L. (c.v.qazvin) plants growth, in nutrient solution (PH 5) on the controlled condition during 15 days have been studied. Maximum yields (dry weight of shoot and root) were obtained at 25 ppm manganese supplied in nutrient solution in comparasion with controls. The shoot/root weight ratio (SRW) showed decrease with increasing manganese in nutrient solution, this decrease in (SRW) confirmed that in toxic levels of manganese shoot have been more affected than roots of pea plant. Length of shoots and roots were retarded below and above 25 ppm of manganese supplied in nutrient solution. Manganese content in young and old leaves and roots of pea plants were determined. The distribution pattern of manganese in 5 treatments was different. Old leaves had the highest, while the young leaves had the lowest manganese content. In all treatments manganese uptake has been increased proportionally with manganese concentration in nutrient solution. Excess manganese above 50 ppm in nutrient solution has caused to unfavorable symptoms including chlorotic (yellowed) areas, brown and necrotic spots and decrease in plant size.
Manganese Toxicity Effects on Chlorophyll Content and Antioxidant Enzymes in Pea Plant (Pisum sativum L. c.v qazvin)
K. Rezai,T. Farboodnia
Agricultural Journal , 2013,
Abstract: Pea plants were grown in different concentrations of manganese (0, 25, 50, 100 and 200 ppm) during 15 days in culture solution. In this study, the effects of toxicity of manganese on chlorophyll content and antioxidant enzymes activity include catalase (CAT), ascorbate peroxidase (APX) and gauacol peroxidase (GPX) were investigated. The data showed that the low concentration of manganese (below 25 ppm) supplied in culture solution, induced decrease in chlorophyll content in pea plants and the high levels of manganese (above 50 ppm) inhibited chlorophyll synthesis in the leaves of this plants. Maximum and minimum rate of chlorophyll content were obtained in 25 and 200 ppm of manganese in culture solution, respectively. Our observations showed the close relationship between increase in manganese concentration and increase of antioxidant enzymes activity in pea plant grown in culture solution. The activity of APX in shoot and roots were higher than CAT and GPX. Data also suggest that the activity of antioxidant enzymes in shoot were higher than roots.

MS Rezai,S Mamishi
Iranian Journal of Parasitology , 2008,
Abstract: Hydatidosis is endemic in Iran. This disease frequently invades the liver and lungs. The frequency of multiple organ involve ment ranges between 11% and 30%. This study revealed a five -year-old female with missed multifocal and multior gan localization of hydatic cyst. The patient presented with a complaint of persistent fever and respiratory distress. In compute rized tomography (CT) of the thorax and abdomen, cystic lesions of different sizes in both lungs, massive pleural effusion were observed. Albendazole, praziquantel, cephazolin and aminoglycoside was started before surgery. Surgical intervention was planned for pleuropulmonary lesions of this patient. With early diagnosis and proper managements, hyda tid cyst in children has an excellent outcome. Today, it is believed that if the operation is performed after a brief course of albendazole or mebendazole, the success rates will be higher.
Genetic and Phenotypic Variability and Factor Analysis for Morphological and Phenological Traits in Soybean( Glycine max (L) Merrill )
B. Siahsar,A. Rezai
Journal of Science and Technology of Agriculture and Natural Resources , 1999,
Abstract: In order to study the genetic and environmental variability of morphological and phenological characteristics and also to gain a better understanding of the morphological basis of yield variation in soybean, an experiment was conducted at Research Farm, College of Agric., Isfahan University of Technology, in 1996. The experiment was arranged in three augmented designs with 285 lines and 5 control varieties. There were highly significant differences among genotypes for all the characteristics studied. The phenotypic coefficients of variability were greater than the genotypic ones for all the traits although the differences for most of them were small. The highest phenotypic and genotypic coefficients of variation, in order of magnitude, were obtained for number of pods per plant, days to flowering, plant height, height of the lowest pod, and number of lateral branches. Heritability estimates and the percent of genetic improvement for these traits and seed weight were high but for seed yield per plant were low. The lowest coefficients of variability were related to number of seeds per pod and days to germination. The results of stepwise regression analysis indicated that the maximum variation in seed yield could be attributed to the number of pods per plant, number of seeds per pod, and 100-seed weight. Factor analysis in addition to emphasizing the importance of yield components, resulted in four factors which determined 97.34% of yield variation. These factors which were indicators of physiological sink and source, with respect to the traits contained, were named as photosynthetic sink, plant architecture, fixed capital, and weight, respectively. In general, it was concluded that in order to improve soybean cultivars, selection should be in favor of plants with stronger structure, higher number of leaves, nods and pods per plant, and higher seed weights.
