Pajouhan Scientific Journal , 2013,
Abstract: Introduction: The purpose of this study was to investigate the Reliability of 3-D scapular kinematics measures of Motion analyzer and Acromion cluster in patients with Shoulder impingement syndrome during humeral elevation and lowering.Material & Methods: 20 Patients (Males=13, Females=7) with Shoulder Impingement Syndrome (mean age: 46.15 years) who participated in the study. They elevated and lowered humerous in frontal, sagittal and scapular movement plane during 8 seconds, using the VICON motion analyzer and Acromion marker cluster. The Scapular 3-D kinematics was measured, using VICON motion analyzer and Acromion marker cluster. Interclass correlation coefficient and Standard error of measurement were used.Results: Participants showed average of age 46.53±13.314 as well as average of BMI 28.14±3.93, and all quantitative and qualitative variables had the normal distribution. Trial-to-trial ICCs for the 3-D scapular kinematics variables for both elevation and lowering condition in the sagittal, frontal and scapular planes ranged from 0.58 to 0.99, which indicated fair to excellent reliability, and the SEM for both elevation conditions ranged from 1.7 to 15.4 .Discussion: The reliability of the three-dimensional scapular attitudes for elevation and lowering phases were very good. The estimation of three-dimensional scapular attitudes using the method of calculation relative to the trunk is reproducible in the three movement planes during elevation and lowering phases and can be used to document the scapular behavior.
Comparison of Spline with Kriging in an Epidemiological Problem

Statistics , 2007,
Abstract: There are various methods to analyze different kinds of data sets. Spatial data is defined when data is dependent on each other based on their respective locations. Spline and Kriging are two methods for interpolating and predicting spatial data. Under certain conditions, these methods are equivalent, but in practice they show different behaviors. Amount of data can be observed only at some positions that are chosen as positions of sample points, therefore, prediction of data values in other positions is important. In this paper, the link between Spline and Kriging methods is described, then for an epidemiological two dimensional real data set, data is observed in geological longitude and in latitude dimensions, and behavior of these methods are investigated. Comparison of these performances show that for this data set, Kriging method has a better performance than Spline method.

Abstract: This study intends to investigate the moderating effect of occupation on the associations between anger and mental health between introverted and extroverted women. Available sampling was used for collecting the data. Sample consisted of 384 women including 192 employed women and 192 housewives women (Mean age = 31.63). A self-administered questionnaire was prepared for the participants. Instruments in the present study included general health questionnaire (GHQ- 28), aggression as well as the scale that assessed respondents’ introversion and extroversion. Results showed that aggression negatively related to mental health. In contrast, there was positive relation-ship between control wrath and mental health. Meaningly, women with high level of conciliation tended to possess high mental health. Furthermore, occupation didn’t play the moderating role in the associations between anger and mental health between introverted and extroverted women.

Abstract: Iran is an active seismic region and frequent earthquakes and because of the active faults, often leads to severe casual-ties caused by structural destruction. Earthquake damage is commonly controlled by three interacting factors, source and path characteristics, local geological and geotechnical conditions and type of the structures. Obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. In this paper, nonlinear geotechnical seismic hazard analysis considering the local site effects was executed and the soil lique-faction potential analysis has been evaluated for the Nemat Abad earth dam in Hamedan province of Iran because of its important socioeconomic interest and its location. Liquefaction susceptibility mapping is carried out using a decisional flow chart for evaluation of earthquake-induced effects, based on available data such as geological, groundwater depth, seismotectonic, sedimentary features, in situ, field and laboratory geotechnical parameters. A series model tests were conducted and then on base of the achieved data the idealized soil profile constructed. A C# GUI computer code “NLGSS_Shahri” was Generate, developed and then employed to evaluate the variation of shear modulus and damping ratio with shear strain amplitude to assess their effects on site response. To verify and validate the methodology, the obtained results of the generated code were compared to several known applicable procedures. It showed that computed output of this code has good and suitable agreement with other known applicable procedures.
The Effect of Intravascular Injection of Ghrelin on the Mean Plasma Concentrations of Insulin and ACTH in Immature Camels Fed with Diets Containing Different Levels of their Energy Requirements

Physiology and Pharmacology , 2010,
Abstract: Introduction: Ghrelin is a peptide hormone secreted from the stomach with both endocrine and paracrine effects. Ghrelin and its mRNA as well as growth hormone (GH) secretagogue receptor mRNAs are expressed in the pancreas and islet cells and regulate insulin release. Also the immounoreactivity of ghrelin is proved to be high in the hypothalamus and parts of the brain responsible for the regulation of the HPA axis. However, the effect of ghrelin on insulin and ACTH secretion before puberty in semi ruminant animals has never been examined. Therefore the purpose of the following research was to determine the effect of ghrelin on insulin and ACTH secretion before puberty in camels. Methods: In this investigation, 12 camels were randomly divided into two groups. Animals in each group were fed with either 50% or 100% energy content in diet for 2 weeks. After 2 weeks camels received 8 μg ghrelin/Kg body weight into their jugular vein for 4 days. Blood samples were collected from jugular vein 20 minutes after injection of ghrelin. Blood plasma was assayed for plasma insulin and ACTH concentrations by a RIA method. Results: Injection of ghrelin in 50% and 100% dietary energy intake significantly decreased the mean plasma concentrations of insulin and increased ACTH secretion in prepubertal camels. Conclusion: The results of these experiments showed that ghrelin’s reducing effect on insulin secretion and its increasing effect on ACTH in prepubertal camels in starvation condition depends on the presence of glucose in their bodies.

Moneta e Credito , 2005,
Abstract: Il Corano costituisce la fonte primaria per gli insegnamenti e le credenze dell’Islam. Mentre la comunità può modificare le politiche sociali ed economiche ispirate ai valori islamici al fine disoddisfare le mutevoli esigenze socio-economiche della società, i princìpi di base dell’economia islamica e il sistema sociale, tuttavia, devono essere preservati. Ci si attende che rappresentantiliberamente eletti collaborino con la società per formulare politiche a sostegno della stabilitàeconomica e sociale, della prosperità economica, dell’istruzione pubblica, delle cure sanitarie,dell’equità economica, di una giusta distribuzione del reddito e di una rete di sicurezza sociale.Tutti i musulmani fisicamente e mentalmente abili sono tenuti a lavorare per il propriosostentamento, e coloro che dispongono di un sufficiente livello di ricchezza hanno l’obbligo dipagare tasse che contribuiscano al finanziamento statale di programmi di welfare o di altra utilitàsociale. La nostra illustrazione del sistema economico islamico è sostenuta da numerosi studiosimoderni di Islam e di economia islamica, non concorda tuttavia del tutto con quelle offerte daesponenti e apparati religiosi legati a un’autorità statale.

Journal of Research in Health Sciences , 2011,
Abstract: Background: Reported data from developed countries showed that annually a high percentage of health budgets consume for controlling and treatment of complications in diabetes disease. Early diagnosis of diabetes, education and health cares, not only prevent progress of disease and complications but also it is cost effective. Methods: For gestational diabetes screening, all pregnant women attending to the health clinics and private clinics in Shahroud City, Iran, were studied in a follow-up study. Women with gestational diabetes, 6-8 weeks after delivery, were tested with 75g glucose. Then, the women were diagnosed to three groups: normal, impaired glucose tolerance (JOT) and overt diabetes. Results: From 63 pregnant women with previous gestational diabetes, 48 women (76.2%) were normal, seven women (11.1%) JOT and eight (12.7 %) got overt diabetes .In overt diabetes group, the age (35.62 ±5.42), gravidity (4.5 ±3.38) and parity (3.25 ±3) were greater than the IGT and the normal group (P < 0.001). In women with overt diabetes, the rate of still birth (57.1 %), gestational hypertension (42.9%), pre-term labor (28.6%), hydramniose (28.6%), abortion (12.5%), respiratory distress syndrome (RDS) (60%), hypoglycemia (60%) and resuscitation (14.3%) in neonate had statistical differences with the normal group. All women with overt diabetes and 42.9% of the IGT group got insulin during pregnancy. Conclusion: As possibility of early diagnosis of over diabetes and prevention of complications in women with previous ODM, is very important. So, postpartum screening in these women is recommended. It is seems that the high age, glycosuria in pregnancy, history of family diabetes, FBS positive in OTT, require to insulin during pregnancy maternal and neonatal complications in women with ODM are the predictive factors to appear overt diabetes after delivery .

Abstract:

Results of the experimental measurements on the partial molar volume of kerosene used as a medium for dissolving TBP are utilized to determine the activity of TBP in the binary kerosene-TBP solution through the application of Gibbs-Duhem equation. The treatment is based on combination of the experimental data with the thermodynamic values available on the compressibility factor of pure kerosene at room temperature. It is shown that the activity of TBP in kerosene has a positive deviation from ideality with an activity coefficient derived as follows:1) at X TBP 0.01: γ TBP = 42.530, 2) at the 0.01< X TBP < 0.2: \"\"3) at the higher TBP concentrations 0.2 < X TBP <0.97: \"\" and 4) at TBP Raoultian concentrations 0.97
