fasaabdi@nima.ac.ir

Abstract: In the mobile environments, due to some specific features such as the bandwidth restriction, displacement in various geographical regions and disconnection, the efficient and cost-effective design of the concurrency control mechanisms, require techniques that are completely different from the distributed databases. Although the concurrency control protocols which are suggested for the distributed environments can be developed for the mobile environments, their efficiency might be very different from that of the distributed environments[9]. In the suggested plan, we offered a new architecture for the mobile database in which a set of cells form a region and one of these cells under the name ‘mobile transaction manager’(MTM) is responsible for the transactions concurrency control which is very suitable for the mobile databases. Also, the suggested concurrency control mechanism which is adopted from an optimistic approach is able to significantly reduce the aborting rate of the transactions in the mobile environment using the transactions early termination mechanism and ignoring some conflictions.

Abstract: We investigate frames, Riesz bases and their dual modular frames in Hilbert C*-modules. A Riesz basis for a Hilbert  C*-modules can have many different dual modular frames which are not necessarily Riesz bases and they always are not unique. We characterize those Riesz basis that have unique duals. Finally, we obtain a necessary and suffieint condition for a dual of a Riesz bases to be again a Riesz bases.

Abstract: Parks are public places where large numbers of people to spend a day in each city for leisure, play, recreation and eating. Many parasitic contaminations spend at least one of their life cycles in the soil to feed and that's why soils especially in busy and crowded areas, if they are infected, they contribute to the transmission of parasitic infections in humans. In this study, the approximately 15 parks were selected and studied proposed named Organization of green space and parks of the province's five southernmost city Fasa, Jahrom, khonj, Estahban and Darab which is relatively large and publicly acceptable. A total of 150 soil samples from different areas of the park including children's play area, the bathrooms, where people sit around the buffet parks and green space sampling were performed. From February 2012 to July 2013 monthly samples were taken, approximately 5 monthly samples would be taken from the city, but also a mixture of soil samples taken from several locations that were intervals. After transferring the samples to the laboratory using sieve 400 and matter of saturated sediment and floating method possible parasitic infection was investigated. Of 150 soil samples, 95 samples (63.4%) with infection and 55 cases (36.6%), no contamination was detected. The city of Darab study with 24 patients (80%) and highest khonj with 13 (43.33%) had the lowest contamination. Also, Fasa, Jahrom and Estahban were contaminated (60%), (56.67%) and (76.67%), respectively. 95 cases of infection were diagnosed in 33 cases (34.7%), 23 (24.2%), 11 cases (11.57%) and 17 cases (17.96%) in order to investigate the children's play area around the restroom, seating people, parks and green space has been around the buffet.

Abstract: The effects of administration of aqueous extract of Alchornea laxiflora leaf at the doses of 100, 200 and 300 mg/kg body weight on Gastric pH and Disaccharidases (maltase, lactase and sucrase) in iron deficient rats were investigated. Thirty six albino rats (51.17±1.02g) were used for the study. Eight rats were fed on iron-sufficient diet while the remaining twenty eight were made iron deficient by maintaining them on iron deficient diets. After five weeks of feeding, haematological parameters (PCV, Hb, RBC, MCV, MCH and MCHC) of the iron-deficient rats were significantly reduced compared with rats fed on iron-sufficient diets (p<0.05). The iron-deficient rats were then treated with the extract, reference iron drug (FeSO₄) and iron-sufficient diets for two weeks. The gastric pH and activities of the disaccharidases (maltase, lactase and sucrase) of rats of the iron deficient group were significantly reduced (p<0.05) compared with the rats fed on iron sufficient diets (control). The result revealed that the level of gastric pH of untreated iron deficient rats was 2.59 while the level of gastric pH of iron-deficient rats administered with aqueous extract of Alchornea laxiflora leaf at doses of 100, 200 and 300 mg/kg body weight increased to 3.26, 3.58 and 3.53 respectively. Furthermore, there was a significant (P<0.05) increase in the activities of disaccharidases of the iron-deficient rats at all doses of the extract. The results indicate that the administration of aqueous extract of A. laxiflora leaves has reversed anaemic conditions in the iron-deficient rats.

Abstract: In the past two decades, there have been proposed several algorithms for the web pages classification problem that majority of them are in the field of evolutionary algorithms such as Genetic algorithm. Moreover, Performance of Genetic algorithm associated with the web pages classification problem is significantly positive. In this paper, we try to improve both operators crossover and mutation of Genetic algorithm which have upgraded performance of this algorithm on the web pages classification problem. Then, We have attempted to find an appropriate adjustment of two operators: crossover and mutation and the most possible and proper examples in each generation, and then use the stated samples in subsequent generations. In other words, we have tried to maintain good features and good examples of each generation to pass on future generations. It can be called the exploitation of knowledge problem, expresses that we used the previous steps to take next steps. We also examine aspects of exploration and exploitation by setting the operators: crossover and mutation. Thus, the proposed algorithm has been moving in a right direction to find the best example or classifier. Furthermore, we have tested the proposed algorithm on benchmark datasets such as Conference, Course, Student. Our conclusion shows better performance of the proposed algorithm in comparison to basic Genetic algorithm, NB and KNN classifiers. The proposed algorithm shows 97% accuracy on a dataset Course.

Abstract: In the research, we ask for introducing manager's communicational skill factors and it's relation with organizational performance. So finally, by using different models and negotiating with respected teachers, we determine five indexes for manager's communicational skills which are below: 1-expressivity, 2- empathy, 3- supportiveness, 4- positivity, 5- equality. After determining manager's communicational skill indexes and their priority, we ask for doing an effectiveness test of the skills on employee's organizational performance. In continue we would reply to the question: "Shemiranat County has desirable relation with employees or not? At the end, we evaluate performance methods by consider to communicational skills in Shemiranat welfare office. Our research society is composed of supervisors and deputies of different departments and experts which have bachelor regardless their degrees (educational certificates) but by consider to the gotten statistics from personnel department Shemiranat welfare office and related departments. The total employee number in the County is equal to 720 persons. So our statistical society is composed of 340 persons with purposed attribute.  In the research, we used library studies and interview with teachers and experts for data gathering tool in determining manager's communicational skill factors, and a pretest in one phase was performed for evaluating related propositions from questionnaires and for evaluating questionnaire reliability before doing final test in the research. So 40 questionnaires randomly distributed in focused society and after gathering the questionnaires by using the stability coefficient in SPSS Software, we calculate α Cranach in the research. The quality for the coefficient was equal to 0.915 which show high reliability for the questionnaires. After performing a pretest by consider to statistical society number, the studied sample volume was determined and equally the questionnaires randomly distributed among employees in different departments. After completing them, opportunely 177 questionnaires were received completely. At the end, after data entering and analyzing them, we conclude the below results: The research results show that manager's communicational skill factors (expressivity, empathy, supportiveness, positives, equality) affect on organizational performance. Also, it's proved that organization managers haven't desirable communicational skill managers with employees and relation between communicational skill managers and employees organizational performance is inappropriate thought not having appropriate between communicational skills. In dispatching index priority by Friedman test, it's proved that the highest average rank is related to empathy and the smallest is related to equality.

Abstract: Comparative study of biodegradation of spent lubricating oil by Aspergillus niger and Bacillus subtilis was studied for 16 days. pH, turbidity, nitrate, phosphorus and Gas Chromatographic analysis (GC-MS) of the medium was carried out. The result showed lower pH, nitrate and phosphorus level in B. subtilis medium compared to A. niger medium and the control. The GC-MS revealed that more compounds were degraded by B. subtilis than A. niger. Methylbenzene, ethlybenzene, hexadecane were degraded into benzene and hexadecanoic acid while Azulene and benzene were not degraded further by both organisms. This study suggests that B subtilis grows and metabolize compounds in spent lubricating oil better than A. niger.

Abstract: The present study was carried out to investigate the anti-diabetic activity of aqueous extract of Curcuma longa rhizome in both normal and alloxan induced diabetic rats. Alloxan-induced diabetic and non-diabetic rats were administered orally with aqueous extract of Curcuma longa rhizome at 200 mg/kg for 28 days, after which the blood glucose, protein, albumin and lipid profile were determined and compared with the normal control. There was a significant (p<0.05) increase in the level of blood glucose, total cholesterol, Low Density Lipoprotein (LDL), triglyceride (TG) and a significant (p<0.05) decrease in the level of High Density Lipoprotein (HDL), total protein, albumin and body weight of the diabetic untreated rats. Oral administration of aqueous extract of Curcuma longa rhizome at a dose of 200 mg/kg body weight for 28 days to diabetic rats resulted in a reversal of the above diabetic conditions. Phytochemical screening of the aqueous, acetone and ethanolic extract of Curcuma longa rhizome revealed the presence of alkaloids, cardiac glycoside and resins while flavonoids, tannins, saponins, balsams and phenols were not detected in all solvent extracts. The data from this study suggest that the aqueous extract of Curcuma longa rhizome used in the study possesses anti-diabetic activities and could be used for the management of diabetes and associated metabolic alterations.

Abstract: The future of modern Iraq needs revolutions having changed its power structure and identity to cause revolutions in geopolitics and Middle East actors. The presence of Shiites and Kurdish in power structure of Baghdad, the elimination of vengeful regime of Baath, the change of “Arabic- Sunny “to “Arabic-Shiite –Kurdish” in political environment of Iraq, the presence of trans-regional of US and other regional actors in the preparation and revolution trend of modern Iraq have forced Iran to make special political strategies of security to these realities. There are concerns including presence of Shiites in the top of political pyramid of Iraq, Kurdish agent, border issues, and the interests of regional actors, explaining and compiling the strategic approaches of Iran in Iraq. Now, according to above issues, what scenarios can be design for the future of foreign policy of Iran against Iraqi revolutions? Effective trends have been investigated by writing scenario method. After knowing trends and strategic progressives, progressives’ position without above certainty which now are most important ones, has been determined by using experts’ view (professors of universities, and researchers who are activate in this field), and non-certainties of “ religious challenges and challenges resulting from ethnic identities “ and “ political- strategic effects “ and “ the interests of international and regional competitors of Iran in new Iraq “ have been considered as “ most important non certainties “. According to the significant relation of three non-certainties, three-dimension environment has been formed. Strategic scenario environment of foreign policy of Iran will be compiled and explained in future with regarding appropriate combination for designed environment.

Abstract: This study develops to employ time-varying boundary layer thickness in order to obtain optimum results for Decouple Sliding-Mode Controllers (DSMC) from the point of view of settling time and declining tracking-error. Sliding-mode controllers based on a time varying boundary layer thickness are more preferable to the fixed-boundary layer method for tracking. All the Sliding-mode controllers contain two principal and cardinal sections. The first section is the reaching mode or reaching condition, which is also called nonsliding mode. The second section is the sliding condition in which the trajectory essentially tends to the origin of the phase plane. The variation of Pareto-set achievements, which contrast each other, leads to selecting the best results from this Pareto front.

Abstract: Germplasm identification and characterization is an important link between conservation and utilization of plant genetic resources. The present study was conducted to assess the phenotypic variation/diversity of 10 germplasm accessions of Finger millet (Eleusine coracana (L) Gaertn) from diverse locations in the geographic region of Northern Nigeria during the 2008, 2009 and 2010 cropping seasons. Randomised Complete Block Design (RCBD) was used for the study and field data were analysed based on phenotypic characters.  Phenotypes were found to express significant diversity for plant height, 1000seed weight, leaf length and number of tillers. The results were analysed using ANOVA model and showed that plant height in accession Ex-Kwi was significantly different from all the other nine accessions while the highest leaf length which was recorded in Ex-Riyom  was significantly different (p<0.05) from accession Ex-Dantse. Similarly, significant variations were observed in the number and length of fingers, and 1000seed weight across all the accessions. Cluster analyses revealed six distinct groups, with one landrace forming an independent colony.  Our results suggest a high phenotypic variability, which could exist among the selected morphological traits.

Abstract: This investigation was conducted during two seasons (2012 and 2013) at the Central Laboratory for Agricultural Climate (CLAC) Dokki, Agricultural Research Center (ARC), Giza, Egypt. The experiment aimed to study the effect of four different sowing date (March 23^rd, April 2^nd, April 12^th and April 22^nd) and four Squash hybrids (Cucurbita pepo L. Eskandarany, Marzouka, Revera and Rosina). The experimental design was a split-plot with four replications. Squash plants (Cucurbita pepo L.) were planted in clay soil. Number of leaves and plant fresh and dry weights were measured after 90 days from each sowing date. Mineral nutrient contents (nitrogen, phosphor and potassium) were analyzed in the mature leaves after 60 days from each sowing date. In addition, total yield (kg/plant) and fruits (number/plant) were measured for each hybrid in each sowing date. The accumulative growing degree days (GDD) for each hybrid was calculated for different phenological stages depending on planting date and both maximum and minimum air temperature at Dokki site. Results confirmed that, using different sowing dates for the four squash hybrids had an effect on vegetative growth parameters (Number of leaves, Plant fresh weight and Plant dry weight), nutrients content on leaves (N, P and K) and yield. In addition, highest values of vegetative growth parameters, nutrient contents and total yield and accumulated GDD were obtained from the second sowing date and Eskandarany hybrid. Economic evaluation indicated that the second sowing date and Eskandarany hybrid had highest net return (L.E)/feddan. Finally, a polynomial relationship between the total accumulative GDD and the total yield for four the hybrids were found (determination of coefficient) R².
