Plants were found to be the best alternatives to available synthetic antiulcer drugs which are known to possess unwanted side effects. Plant drugs are relatively safe and effective. So following the folklore claims, lannea coromandelica had been investigated for the antiulcer activity. As a part of standardization the total phenol content in methanol and aqueous extracts of the leaves was determined spectrophotometrically using a quercetin standard graph and content was found to be 17.3 and 15.6 mg quercetin equivalents per g weight of the extracts respectively. Further, methanol extract was analyzed through HPTLC finger printing for the presence of flavonoid biomarker, quercetin. It was found that 1mg of extract contains 60.66 microgram of quercetin. The antiulcer activity of methanol and aqueous extracts of leaf has been investigated against ethanol and indomethacin induced gastric ulceration at two doses, 200 and 400 mg/kg and results proved the activity comparable with synthetic and natural (quercetin) standards following the favorable results from acute toxicity studies.

This study aimed to investigate the effects of educational management, based on human relations, on increasing efficiency of public high schools\' teachers in Iran. The research method was no-experimental and survey method. Data collecting tool consisted of two 58 and 19-item, 5-choice LIKRET type questionnaires. Statistical population was all teachers and principals of public high schools of I.R.IRAN in the academic year of 2009-210 which includes 49836 teachers and 6881 principals. The statistical sample has been consisted of 800 teachers and 80 principals. To estimate the size of the sample case we used KREJCIE and MORGAN Table and sampling method was random stage cluster method. In this study According to the research hypotheses, there is a significant correlation between teachers\' skills in human relations and efficiency of principals. High school principles are trying to move from the traditional management style toward management based on human relations and by using these skills provide the background for more efficiency of teachers. The principals of high schools have been recommended that provide conditions in order to recognize the needs, abilities, talents and abilities of their teachers and staff and attempt to create an atmosphere of friendship and intimacy in school.

Ketamine is a one of prior injectable anesthetics that it\'s usefulness to induce anesthesia or deep CNS suppression in oral administration has not been approved absolutely. Besides Chelidonium majus L. (family Papaveraceae), or greater Celandine, is an important plant in western phytotherapy and in traditional Chinese medicine and exhibit a broad spectrum of biological activities (anti-inflammatory, antimicrobial, choleretic, immunomodulatory, antitumoral, hepatoprotective, diuretic, antitussive, lowering blood pressure, antibilious, cathartic, wormroot in internal uses. Epispastics and flesh wound amneliorator in external uses, anti-osteoporotic activity and radioprotection and eye-regenerative effect). Likewise the herb\'s other important medical properties are: calmative, narcotic, analgesic & anti spasm. As it seems that co administration of celandine and ketamine cause more effective & deep CNS depression effects and also alleviate some of ketamine adverse effects such as spasm, hypertension and eventual convulsions. Ten male cats received different orally doses of Ketamine, celandine & diazepam. Each animal was observed continuously for CNS depression as standard grades on the behavioral scale. Quantal data were obtained by determining the percentage of animals which lost the reflexes (graded as 5 scores) for each dose. Peak scores for each dose and the percentage of animals that reached each peak score is given. Different doses of Ketamine, celandine and diazepam showed dose dependent effect in CNS depression. But, ketamine only exhibited the vigorous effect (score 5). Celandine administration in any Doses could induce only Immobility in animals so as has stronger effect in compare with diazepam. Also celandine reduced pain sensation dose dependently but all of cats reacted to pain in diazepam administration. Also all of animals showed no reaction to pain only in higher dose of ketamine. Results showed that Celandine has better synergism with ketamine to induce vigor CNS suppression in compare with diazepam.

Drought stress and nitrogen amounts can be effective on yield and yield components. And both these factors can be wheat yield limited. In order to determination of wheat yield in water and nitrogen limit condition, a farm experiment was done on winter wheat, Sayonz cultivar. This experiment was conducted in 2009-10 and 2010-11 in a farm located at 5 kilometer from west of Shirvan city. The experimental design was split plot in basis randomized complete block with four replications. The experiment treatments consisted of four levels of irrigation, I1= complete irrigation (field capacity (FC)), I2= 80% field capacity, I3= 60% field capacity and I4: without irrigation (dry farming) main-plots, and four levels of nitrogen fertilizer consumption, N1= 0, N2= 100, N3= 175 and N4: 250 kg/ha as sub-plots. In this research were measured factors of the number of seed per ear, 1000-seeds weight, biological yield, seed yield and harvest index. The results of experiment showed that effect of irrigation and nitrogen fertilizer treatments was significant on factors measured. So that for all factors, the highest amount obtained from complete irrigation and consumption of 250 kg/ha nitrogen fertilizer (I1N4). Generally from results of this research was concluded that for obtaining the highest wheat yield in Shirvan region, complete irrigation and consumption of 250 kg/ha nitrogen is very ideal.

In order to study of effect of vesicular arbuscular mycorrhizal (VAM) fungi coexistence and water deficit on maize, a field experimental in split plot as complete randomized block design with three replications was conducted in 2011 in Goharkouh region, Iran. VAM treatments were composed of V0: Without consumption of, V1: Consumption of 80 kg/ha VAM, V2: Consumption of 100 kg/ha VAM, V3: Consumption of 120 kg/ha VAM and V4: Consumption of 140 kg/ha VAM, as main-plots, and water stress treatments composed of S0: Without stress (optimum irrigation), and water stress at two stages of growth S1: 20 days after appearing male flowers and S2: 20 days after appearing female flowers as sub-plots. In this experiment, factors of the number of seed per ear, biological yield, seed yield, harvest index and protein content were measured. The results showed that the most amount of the number of seed per ear, biological yield, seed yield and harvest index obtained from S0V4 treatment. For factor of protein content, the highest amount was achieved from S2V1 treatment.

The sequential extraction of Cd, Cr, Ni, Pb, Cu and Zn in atmospheric dust particles collected along ten high traffic roads in Kano metropolis were carried out. Hence, analyses of the extracts were done using flame atomic absorption spectrometry (FAAS). The samples analyzed for metals indicated high levels of Cd, Cr, Ni, Pb, Cu and Zn in the atmospheric dust samples, ANOVA show discernible variations in levels of metals between the sites. A Pearson correlation matrix was used to define the relationship between the metals. The sequential extraction showed significant amount of Cd were associated with CO32- and Fe-MnO fractions especially during the dry seasons. For Cr and Ni, their occlusion in crystal lattice of the soil fraction exhibited the highest percentage. Pb in the particulate dust samples is significantly associated with the carbonate bound fraction with range of 8.81 – 64.69% across the season. The behaviour of Cu is quite different from other metals in that percentage fractions are higher in the organic bound. As for Zn, significant amount were associated with the residue fractions ranging 0.96 – 87.50% across the seasons. This study revealed that particulate dust contamination due to metal such as Cd and Pb implies health risks to human, living or carrying out daily activities along the corridors of these roads.

Competition intensity in marketplaces and realizing the importance of retaining customers for organizations cause them to take gradually steps towards developing and maintaining long-term relationships with customers as well as promoting services. The purpose of the study is to Review of automated service quality status at Saman Bank. In this study to evaluate the quality of automated bank service, the tools suggested by AL- Hawari, Ward, and Hartley and also to measure customers loyalty, image and awareness, the tools suggested by Kayaman, Arasli, and Kim, regarding local circumstances and Persian bank specifications, are used. The importance of variables in customers’ point of view and the bank’s success extent to develop each variable have been studied. The present research is a descriptive study (correlation type) performed by survey method (cross-sectional type). The statistical population of the study includes all customers utilizing at least one of the Saman Banks’ automated services in north provinces, and the sample is 266 people out of these customers.\nThe data indicate that the Automated Service Quality affects directly customers’ loyalty, all Automated Service Quality dimensions except core service affect directly customers’ image and there is also no significant positive relationship between the Automated Service Quality and customers’ Awareness. There is a mutual (two-way) relationship between loyalty and image. Awareness has direct effect on image, on the other hand, Awareness has no significant positive effect on customers’ loyalty. Finally the utilized compound model in the study has been improved by using obtained data.

The goal of our research is to reduce the number of inspection points for cylinders and bell shapes while maintaining almost the same tolerance zone, so the time and cost is reduced. According to Cantilever Beam Theory that states the maximum deflection on the cylinder being machined using lathe machine, occurs at the free end of the cylinder. Hence the maximum dimensional error can be expected to be at the free end of the cylinder being machined. A big reduction in the number of the inspection points has been achieved. The number of sampling points has been reduced, in cylinders, by about 74.9 % with a difference in a tolerance zone of 3.7%. A big reduction, also, has been achieved in sampling bill shapes. It reached to about 66.75 % with a difference in a tolerance zone of 1.6%.\n So number of inspection points can be expected to be maximum at that region. The same thing can be said for the maximum deflection of the cutter used in cutting the bell shape. The cutter deflection will be maximum at the free end of the cutter, so maximum dimensional error can be expected at the bottom of the bell shape. Hence the sampling points are expected to be dense close to that region.

In this paper a comparison study has been made between three different layouts for manufacturing self actuating traction drive speed reducer proposed by Flugrad and Qamhiyah in 2005. The first layout represents the actual process layout used to manufacture that speed reducer by Abu Jadayil and Mohsen in 2010. The second and the third layouts are based on part assignments. The second layout was made so as to minimize the sum of voids and exceptions. Then it is modified to take into account processing times of different parts of that speed reducer. Twenty six parts and ten different manufacturing processes were used in the analysis. A third layout was made for two manufacturing cells only instead of three found as optimum in the second layout. A comparison between the second and the third layout shows that the second layout is the best layout according to minimum sum of voids and exceptions, while the third layout is the best according to maximum sum of processing times inside the formed manufacturing cells.

Jordan as one example of Middle Eastern countries suffers from the problem of workers turnover. This paper analyzed this issue numerically and by building a statistical model to find out the main reasons causing this problem as a first step towards the right solution. Data were collected from males and females in factories inside the three main industrial cities in Jordan and from factories located outside those industrial zones. Five main categories for workers turnover were studied and investigated. The salary, the working environment, the helpfulness and corporation of the management, the worker psychological state and relationships with surrounding environment, and the services provided by the employer to the employee. Statistical analysis of the results showed that the main reason for turnover in industrial cities is the salary. The effects of both salary and the residency were analyzed and studied in details. Salary is the only criterion which is better outside the industrial zones from the inside ones. Workers in factories located outside industrial cities suffer mainly from working conditions and environment, which force them to leave. Salary is a main issue especially for workers living in big cities like the Capital Amman

Mycotoxin , nutritional and biochemical studies fruits of velvet tamarind (Dialium guineense Willd) were conducted in the department of Forestry and Environment (Forest Pathology unit) and Food Science Laboratories in the Rivers State University of Science and Technology. Total aflatoxin of healthy fruitswas 3.7 -0.02, infected fruits, 3.8-0.01 and the standard 4.0-0.0.15. Moiture and toatal carbohydrate were found to be higher than infected fruits while ash ,ether,extract,protein and fibre were lower. Vitamin C, iron and magnesium were higher in infected fruits than healthy fruits. Saponins,oxalate and tannins were higher in the healthy than infected fruits while phytate was lower in healthy than infected fruits.There was no record of cyanogenic glycosides (HCH) in either healthy or infected fruits.

Background: Rheumatoid Arthritis (RA) is the most common chronic disease involving joints. Anti-CCP as a specific antibody is a reliable index to early diagnosis of RA. Disease-modifying Anti-rheumatic Drugs (DMARDs) can reduce progression of RA joint destruction. \nObjectives: The present study aimed to investigate the effects of DMARDs in reducing serum Anti-CCP. \nMethods: A cross-sectional study was performed on 51 RA patients according to the American College of Rheumatology (ACR) classification criteria, who referred to the Rheumatology Clinic. Finally, 30 patients including 22 females and 8 males were recruited. Treatment with DMARD group started at the beginning of the study. At first and 6th month of the study, clinical findings and disease activities were recorded and Anti-CCP was measured.\nResults: At the beginning and the end of the study, morning stiffness for more than 1 hour and involvement of 3 areas were, 28 (93%) and 12 (40%), respectively. Indicators of disease severity in patients, the mean ± SD serum levels of ESR at the beginning and end, were 40.7 (30-59) mm/1h and 13.4 (9-86) respectively. Anti-CCP at the beginning and end of the study was 141.83 (65.8-101.09) U/ml and 65.8 (62-92) U/ml respectively. DAS28 and RF positive and CRP positive were significantly different at the onset and at the end of the study (P value <0.05).\nConclusions: Measurement of serum Anti-CCP is a helpful index of treatment response and monitoring of treatment efficacy in patients with rheumatoid arthritis.
