EFFECT OF POPULATION DENSITY AND DOSE OF NITROGEN AND POTASSIUM FERTILIZERS ON PERFORMANCE OF GREEN BEAN (PHASEOLUS VULGARIS)
(University of Eloued جامعة الوادي, 2018-01-01) Hussein, A.; Benmoussa, M.; Abbad, M.
This experiment was executed in a split randomized complete block design with three replications. Two plant densities (D), (D1; D2) equal to one plant and twoplants per pot and seven fertilizers doses (F), (N0 K0; N1 K0; N1 K1; N2 K0; N2 K2; N0 K1; N0 K2) were investigated. N0, N1 and N2 equal to 0, 0.46, and 0.92 g urea while, K0, K1 and K2 equal to 0, 0.42 and 0.84 g potassium sulfate, respectively. The results showed that the treatments had no effect on the number of branches per plant and vice versa the interaction. Lower plant density (D1) and higher dose of both elements (N2 K2) significantly increased shoots dry weight, number of pods and pod yield per plant while, in second season the higher value of those yield parameters was obtained at lower dose of nitrogen (N1 K0), the interaction of those treatments increased significantly plant dry weight. The interaction between lower plant density (D1) and nitrogen irrespective of their quantity and potassium, (N1 K0; N1 K1; N2 K0 and N2 K2) increased the number of pods and pods yield per plant, while the greatest yield per hectare was obtained at density planting (D2) receiving higher doses of both fertilizer and lower dose of nitrogen (N2 K2: N1 K0) at the first and second season respectively.

ASSESSMENT OF CONCENTRATION CHANGES AND TRAFFIC EFFECTS ON CARBON MONOXIDE LEVEL IN THE CITY OF YASUJ, IRAN
(University of Eloued جامعة الوادي, 2018-01-01) Porkavosh, S.; Marioryad, H.; Shirazi, A. R.; Rezaei, S.; Hassani, G.
Background and objectives: Identification and measurement of air pollutants are the first steps to manage air pollution. Because many of these pollutants can have adverse effects on ecosystem and human health, no knowledge of the quality and quantity of pollutants can cause problems in identifying, determining concentration and, if necessary, controlling. The purpose of this study was to evaluate the changes in carbon monoxide (CO) concentration and the effect of traffic on the level of this pollutant in the city of Yasuj in Iran. Materials and methods: In this study, the first action was the selection of study sampling stations, where were considered to be ten major squares of the city. The samples were collected in cold and hot seasons at traffic hours (between 7am and 22pm). In the next step, the direct-reading instrument (First Check) was used to measure the concentration of air CO. Traffic intensity measurements were also performed visually. Finally, the data were analyzed using SPSS 16 software. Results:The mean CO concentration in the city of Yasuj was estimated at 1.01 ppm. The maximum concentration of this pollutant was measured in the hot season and in night hours on the first days of the week In addition, the results of this study showed that increased traffic intensity enhanced linearly the CO concentrations. Conclusion: Although the results of the present study indicated the CO concentrations less than the allowable environmental standard limits, but since even small amounts of air pollutants can cause damage to the health of exposed people and environment, the necessary interventions should be taken into account in order to control the air pollutants for maintain and improving the existing conditions.

INVESTIGATING THE ROLE OF THE UNITED STATES IN THE INTERNAL AFFAIRS OF IRAN IN 1953 TO 1978
(University of Eloued جامعة الوادي, 2018-01-01) Sohrabi, H.; Mollaali, A.; Askaritybi, F.
The purpose of this study was to investigate the role of the United States in internal developments in Iran through a descriptive and analytical method based on the theoretical framework of Wallerstein's global system theory and Imam Khomeini's anti-Semitism theory. According to the theory of these two United States authorities during the years before the Islamic Revolution, during the period from 1953 to 1978, the real case of colonialism and the role of the center of the country has been in the exploitation of the surrounding countries, including Iran. Based on the findings of this research, the post-coup period of 19 August 1953 to 11 February 1979 is one of the most important historical stages in Iran's foreign policy, in which foreign policy has changed in complete turning from a negative balance to dependence and subjugation. At this point in time, the United States' behavioral pattern in Iran's internal affairs was a comprehensive interventionist intervention in support of the Pahlavi regime. This interventionist pattern, through strategies that strengthened the puppet regime in Iran, included the support and support of the coup d'état of August 19, the imposition of military coup d'état by Ardeshir Zahedi, the return of the Shah to the country after the coup, the suppression of the Shah's regime against groups and popular parties, Supporting the Western-style reforms in the name of the White Revolution, suppressing the June 5 uprising, and the power of the Bakhtiar civilian government and the possible order for a bloody coup during the fall of Bakhtiar. The Islamic Revolution of Iran, based on the theory of Imam Khomeini's anti-Semitism as the most important internal change in Iran and the world, has contributed to the collapse of the US regime in Iran, with religious teachings. Imam Khomeini, in light of the success of this pattern, advocates the oppressors of the world to follow it.
EVALUATION OF THE RESULTS OF NON-SURGICAL TREATMENT OF FEMURFRACTURES IN CHILDREN AT SHAHID BEHESHTI HOSPITAL IN YASUJ, BETWEEN 2011 TO 2016
(University of Eloued جامعة الوادي, 2018-01-01) Mohammadi, H. R.; Rafiee, A.; Motlagh, A. H.
Introduction: Femoral shaft fracture is fairly common in children and due to the potential risk of bleeding and shock, it is important to diagnose and treat appropriate and timely treatment of this fracture. The femur bone is the largest bone in the body and has complex anatomy and is usually followed by direct and indirect severe trauma such as car crashes or falling from the height of the fracture. Materials and methods: All patients who were admitted to the orthopedic department of Yasuj Shahid Beheshti Hospital between 2011 and 2016 were identified. The total number of these patients was more than one hundred cases, of which there were some cases in the registration of the diagnosis in the case, and some were not referred to the hospital after the discharge from the hospital, which were excluded from the study.76 patients were examined, of which 26 were female and 50 were boys. The lowest age of patients was 15 days and the highest age was 15 years. Results: In terms of the mechanism of fracture, the most commonly reported car accident (34%) and after falling (falling) are 28%. Unusual mechanisms such as pathologic fracture (4%) or birth Fix (2%) or child abuse (2%) and fracture during physiotherapy (2%) make up a total of 10% of the mechanisms. The most common fracture age is in the age group of 2-10 years (66%), 10-15 years old (28%) and under 2 years old (6%). Defeat in boys (68%) is more than girls (32%) appear. Discussion: In this study, 88% of patients were treated with cure and 12% with surgical procedures, patients treated with surgery, two groups: 1) those who have cured a remedy fail.2) Adolescent ages, usually with fractures associated with displacement.
COMPARISON OF THE INCIDENCE OF HYPOCALCEMIA IN THYROIDECTOMY DUE TO MULTI-NODULAR GOITER AND THYROID CANCER
(University of Eloued جامعة الوادي, 2018-01-01) Mansourian, A.; Paymard, A.; Khastavaneh, M.; Parvizian, R.; Jahantab, M.
Introduction: Thyroid disease, especially nodular lesions, is one of the most common diseases in recent years. Non-toxic nodular goiter multinodular is a common thyroid problem, which increases with increasing age. Multi-nodular malformation can cause Excessive glandular enlargement and more than any other thyroid disease with glandular neoplastic involvement. In fact, multi-nodular goiter is benign, but there are some focal regions of malignant changes that cannot be detected by physical examination, ultrasonography, or radioisotope scanning, and only after extraction of the tuber by surgery and its pathological examination. Method: This descriptive-analytic study was a retrospective study in which 180 patients underwent total thyroidectomy, which was the cause of this multi-nodular goiter or thyroid cancer. This study was conducted to investigate the patients referred to Shahid Beheshti Hospital in 2016 and 2017. Meanwhile, 86% of the patients were female with thyroidectomy. The cause of thyroidectomy was multiple nodular goiter and thyroid cancer. The cause of the action was based on the case, the description of the practice and the doctor's opinion, as well as the answer to the pathology sample. In order to select the sample, all files of patients under complete thyroidectomy were selected and counted. Discuss: The aim of this study was to compare the incidence of hypocalcaemia in thyroidectomy with the cause of multiple nodular goiter and thyroid cancer. The first finding from the present study was that there was no significant difference in incidence of hypocalcemia in thyroidectomy due to MNG and thyroid carcinoma. Since surgery has been performed in a university hospital with a large number of patients and has been carried out by surgeons with sufficient surgical experience and skill, there is no significant difference in the incidence of hypocalcemia in thyroidectomy due to the multi-nodular goiter and thyroid cancer, as a result of this issue. Conclusion: The results of this study showed that there is no difference between the incidence of hypocalcemia in thyroidectomy and the cause of multinodulargoiter and thyroid cancer.
DEVELOPMENT OF MATHEMATICAL MODELS FOR PREDICTING THE IRON CONCENTRATIONS OF LAKE OUBEIRA WATERS (NE ALGERIAN)
(University of Eloued جامعة الوادي, 2018-01-01) Alayat, H.; El Badaoui, H.; Abdallaoui, A.; Abrid, D.; El Hmaidi, A.
Facing the increase of surface water samples contaminated by ETMs, usually from the geochemical background, the emergence of new human diseases is worrying. To solve this problem, we have developed several models based on different learning algorithms qualified by high performance, using different transfer functions. We have shown that all the Neural Models presented more or less important performance compared to the one based on multiple linear regressions. The best revealed model ANN in the current work is a MLP type that uses the Levenberg-Marquardt algorithm as a learning algorithm, with Tansig and Purelin as transfer functions, respectively in the hidden layer and the output layer. This successful model can be considered as an important tool of great effectiveness in the context of environmental prediction and especially in anticipation of the iron contents of the Oubeira Lake water.

(University of Eloued جامعة الوادي, 2018-01-01) Karami-Mohajeri, S.; Farsipour, B.; Mozaffari, A.; Faghihi-Zarandi, A.
Context: Volatile organic compounds (VOCs) are one of the most important pollutants in the air that can lead to a broad range of adverse health effects. One of the sources of VOCs is their emissions during copper concentration in copper factories. Aims: To evaluate the concentration of VOCs in the concentration plant of a copper factory and the impact of these pollutants on worker’s health. Settings and Design: This was a cross-sectional study in a concentration plant of a copper factory. Methods and Material: Gas chromatography-mass spectrometry was used for measurement of VOCs in the air samples collected by activated charcoal tube. Additionally, urine and fasting blood samples were taken for urinalysis and routine Hematological and biochemical tests of kidney and liver functions. Statistical analysis used: data were analysed using the student's t-test for difference of mean by Graph pad Prism foe windows (version 6.07) Results: Fourteen VOCs were identified in the air samples and all parameters except alkaline phosphatase, blood sugar, bilirubin, and monocytes, lymphocytes, and eosinophils counts were significantly increased. Conclusions: The average exposure of workers to VOCs did not exceed the current TWA. However, evidence of subtle, sub-clinical and pre-pathologic early blood, liver, and kidney dysfunction was evident in exposed individuals.

(University of Eloued جامعة الوادي, 2018-01-01) Alamdari, H.; Ahmadizadeh, A.
The purpose of this study is to investigate the effect of safety self-efficacy and self-regulation on workplace accidents among the employees of educational hospitals in Boyer Ahmad City. This is a descriptive-correlational research using the field method. It is an applied research in terms of nature and a cross-sectional research in terms of time. The study population consists of the employees of Boyer Ahmad hospitals with a total number of 1494 employees in 2017. A total of 306 employees were selected from the population as the sample size using the Cochran formula. The results showed that self-efficacy and self-regulation variables (promotion focus and prevention focus) influence the work-related accidents. Self-efficacy, self-regulation and prevention focus have negative effects on workplace accidents while promotion focus has a positive impact on it. The results of multiple regression also showed that in total 0.62 percent of occupational accident changes are explained by self-efficacy and self-regulation variables.
IDENTIFICATION OF FACTORS CONTROLLING THE QUALITY OF GROUNDWATER IN MITIDJA PLAIN USING INDEXING METHOD AND STATISTICAL ANALYSIS
(University of Eloued جامعة الوادي, 2018-01-01) Zamiche, S.; Hamaidi-Chergui, F.; Demiai, A.; Belaidi, M.
In this paper, we describe the hydro geochemical processes in the aquifer of Mitidja using hydro chemical data, statistical analysis and Water Quality Index (WQI) to identify evidence of contamination processes. Two factors were found that explained hydro chemical evolution in the aquifer. These factors reveal the existence of an intrusion of seawater and mechanisms of nitrate contamination of groundwater. The effect of each parameter on the WQI show that the highest mean effective weight value belongs to the TDS, NO3- and SO42- parameters. These results indicated that natural and anthropogenic activities are responsible for the degrading of groundwater quality in the Mitidja plain.
EXPERIMENTAL STUDY OF THE HYDRAULIC JUMP IN A HYDRAULIC JUMP IN A SLOPED RECTANGULAR CHANNEL
(University of Eloued جامعة الوادي, 2018-01-01) Kateb, S.; Ghomri, A.; Debabeche, M.
The hydraulic jump in a sloped rectangular channel is theoretically and experimentally examined. The study aims to determine the effect of the channel’s slope on the sequent depth ratio of the jump. A theoretical relation is proposed for the inflow Froude number as function of the sequent depth ratio and the channel slope. An experimental analysis is also proposed to find a better formulation of the obtained relation. For this motive, five positive slopes are tested. The relations obtained are recommended for designing irrigation ditches.
HYDROGRAPHIC NETWORK EXTRACTION AND WATERSHEDS DELIMITATION SOFTWARE OF THE SOUTH ORAN NORTH WESTERN ALGERIA
(University of Eloued جامعة الوادي, 2018-01-01) Ayache, A.; Bennia, A. R.; Lebid, S.; Hellal, B.; Maacho, A.
The development of space technology has allowed a better understanding and effective use of water resources through the use of Digital Terrain Models or DTM. Mapping the river system from DTM has two objectives, namely identifying first topography descriptors like hills, ridges and valleys of watersheds and second hydrological parameters to map areas of runoff recovery for a more efficient development and also a better representation of the actual land occupation. Our work is part of a methodological approach to satellite imagery processing and mapping of topographic and hydrographic parameters of watersheds. Thus, from DTM one was able to extract the full river system of the region. The results show a remarkable evolution of human activities and especially in areas of high water recovery capacity.

(University of Eloued جامعة الوادي, 2018-01-01) Moshfe, A.; Farhadipour, F.; Manzouri, L.; Jamshidi, A.; Mohammadi, R.
Background: Leishmania infantum is the main cause of kala-azar in Iran. This studyaimed to determine the prevalence of visceral leishmaniasis in children under 10 years old, who live in infested villages of Boyer-Ahmad district, south of Iran, to evaluate the current status of the disease after reservoir host(owner ship dogs) elimination. Material and methods: In previous studies, villages infected with humans and animal reservoirs were identified. The infected dogs were destroyed. Now, 127 serum samples of children from 8 rural area of Boyer-Ahmad district was taken and tested by DAT. They were also investigated to determine the signs and symptoms of the disease. Results: All 127 serum samples were negative for anti leishmania antibodies (≤1:800 titers). 64 and 63 individuals were male and female respectively. The age of 112 cases was 5-10 years old and 15 cases (8.11%) have 1-4 years old. Nobody showed symptoms of the disease. Conclusion: To control the disease, the important factor is reservoir elimination. Previously infected dogs were killed at 2010 in the district. The current results may be due to destruction of dogs. Therefore, according to success of this work, this method is recommended for disease control in other region.
A GREAT RELIABILITY, CAUSES A DECREASE OF FAILURES IN THE ROTATING MACHINES
(University of Eloued جامعة الوادي, 2018-01-01) Bensaci, M.; Chaib, R.
Since industrial machines are prone to multiple modes of failures, or the opportunities for breakdowns and incidents are multiple, and given that the operating factors have a random nature, may cause unanticipated cataleptic failures. To reduce overall maintenance costs, the number of unplanned outages, it is necessary to ensure a great reliability, causes a decrease of failures in the rotating machines and to improve the MTBF of the machine. Thus define the maintenance actions to be carried out and the spare part at the appropriate time, or make selective maintenance. That is why, the aim of this work is to use the law of Waloddi Weibull in order to know at all times the reliability, the MTBF and ensure the availability of equipment.
EXPERIMENTAL INVESTIGATION OF INDUSTRIAL COPPER DEFORMED BY WIRE DRAWING PROCESS
(University of Eloued جامعة الوادي, 2018-01-01) Fellah, L.; Boumerzoug, Z.
The scope of this work is to investigate the effect of the cold deformation by wiredrawing on microstructure and physical properties of industrial copper wires. Copper wires were provided by E.N.I.CA.Biskra (Algeria). We investigated some wires with different strain levels (as received, 1.20, 2.10, and ε = 3.35). X-ray diffraction, optical microscopy, and electrical resistivity measurement have been used as characterization techniques. We analyzed the photographs using “ImageJ” software and DRX patterns using PM2K software. The results revealed that the cold wiredrawing causes a lengthening of grains along the axis of wiredrawing, and introduced large amounts of defects. The results also showed, on the one hand, the decrease in crystallite size, lattice parameter, and the outer cut-off radius, on the other hand, the increase of the electrical resistivity and the dislocation density in the copper wires.
GLOBALIZATION, SOCIAL CHANGE AND NATIONAL SECURITY OF THE ISLAMIC REPUBLIC OF IRAN
(University of Eloued جامعة الوادي, 2018-01-01) Askari, M.
The scholars consider globalization or globalization an obscure, complex, and diverse dimension, as some have considered it process and others have considered it as a project. The nature of globalization in a pessimistic attitude is equivalent to globalization that seeks to homogenize and harmonize the world with the domination of the "hegemon" culture over other cultures. But in an optimistic approach to globalization, there is an overwhelming process that is taking place, due to the expansion of social ties and the promotion of the level of global co-operation. The effects of globalization in Iranian society are also significant as a potential challenge to the social elements and subcultures of the country. These works can lead to challenges that, as a result, affect vital and acquired values and undermine the capacity to legitimize the system. In this article, we are trying to find out how and at what level globalization causes social change and how these changes affect the national security of the Islamic Republic of Iran. The purpose of this research is applied research and is descriptive in terms of research method. Also, the required information is collected using the documentary method. The conclusion of the research is that globalization is a two-way phenomenon, both a threat and an opportunity. In addition to taking advantage of the opportunity and planning for it, one should not ignore the threats of globalization and globalization, and in order to overcome the threats and neutralize the effects and effects of these programs, it is necessary to design coping programs and to stage Executes
