Abstract: Introduction: Mission of Universities is to respond to the needs and expectations of its key stakeholders and specially their students. Quality promotion and continuous improvement of education and research processes in universities of medical sciences is important. Determining of student satisfaction level as the most important indicators to reach the desired quality should be considered. Thus this study with purpose of student satisfaction evaluation from education and research processes in Hamadan medical sciences faculties was performed.Material and Methods: This cross - sectional study was conducted in Hamadan University of Medical Sciences at 2011-2012. 385 students selected from all schools based on stratified method. To measure student satisfaction a researcher made questionnaire consisted of 71 questions related to various aspects of educational services (9 compasses) was used. Obtained data were analyzed using SPSS 16 software the chi-square test.Results: Most of the participants (72.2%) were in the age group 25 to 21 years. 50.3 percent of students were female. Most of students were at the undergraduate level (38.8%) and physician (32.9%). Level of satisfaction for all compasses was at moderate level. Based on statistic result only in internships and apprenticeships compasses satisfaction level showed a significant correlation with studying duration (P<0.05). Also in the teachers counseling, workshops and laboratory activity compasses the stratification level had a significance relation with degree (P<0.05).Conclusion: The results showed that the student’s satisfaction from educational processes is at moderate level. Satisfaction level based on degree of students is different, so managers and policy makers of educational system as well as teachers of various degrees can utilize the present study results to restructure of educational strategy in order to promotion the quality and the satisfaction level of educational services.

Ethiopian Journal of Health Development , 2007,
Abstract: Background: Economically Ethiopia remains one of the poorest countries in the world and malnutrition is one of the major and most pressing health problems; especially among children. Objective: To assess the nutritional status of preschool children in a rural locality of Northwest Ethiopia Methods: A cross-sectional survey was conducted in a rural locality called Gumbrit. Weight and height of the study children were measured and the socio-demographic characteristics of the subjects were collected using a questionnaire. Results: The overall prevalence of malnutrition in the community was high with 28.5% of the children being underweight, 24% stunted and 17.7% wasted. Among the socio-economic variables included in the study only family income was significantly associated with malnutrition. Conclusion: The nutritional status of children in rural communities is affected by low family income. To improve nutritional status of children the full implementation of the poverty alleviation programmes should be considered and appropriate measures need to be taken to support needy families with children.

Abstract: The Asmari Formation is a thick carbonate sequence of the Oligocene-Miocene in the Zagros Basin, southwest of Iran. This formation is located in Bandar Abbas and Coastal Fars regions on the following two sections: Anguro anticline (west-northwest of Bandar Abbas) and Gavbast anticline (southwest of Lar County). The Asmari Formation has diameters of 68 and 26 m in the Anguro and Gavbast sections, respectively. This formation is composed of limestone, dolomitic limestone and an altered form of marl. Based on the results of petrographic analyses, 7 facies were identified in the Anguro and Gavbast sections in the study region. The facies were deposited on the following 3 belts: tidal flat (MF 1 - 3), lagoon (MF 4 - 5) and open marine (MF 6, 7). According to evidence such as the gradual change of microfacies, the lack of main reef barriers, and the lack of slumping and sliding features, the Asmari Formation was formed in a marine environment of carbonate homoclinal ramp type. This environment is composed of the following two subenvironments: the inner ramp and the middle ramp. The comparison of the facies identified in the Anguro and Gavbast sections indicates that Gavbast section is mainly composed of lagoon facies. Moreover, the Anguro section demonstrates more facies diversity than Gavbast section.

Case Reports in Obstetrics and Gynecology , 2011, DOI: 10.1155/2011/181034
Abstract: Following one year of secondary fertility, a couple conceived with a quadruplet after transfer of three embryos through IVF-ICSI. At 36 weeks and 2 days of gestation, the mother developed gestational induced hypertension and delivered the next day by caesarean section. Pathology confirmed the zygosity to be trichorionic quadramniotic and all four babies were discharged home with their mother on postoperative day 3. Herein, we describe a successfully managed high-risk pregnancy case. A review of the literature was conducted and to our knowledge no other cases with similar criteria ever reached such advanced gestational age.

Abstract: Some new mono-and bis-polycyclic aromatic spiro-β-lactams and bis-non spiro-polycyclic aromatic β-lactams have been synthesized from imines derived from anthracene-9-carbaldehyde, 2-naphtaldehyde and a ketene derived from 9H-xanthene-9-carboxylic acid and phenoxyacetic acid by a [2+2] cycloaddition reaction. The cycloadducts were characterized by spectral data, including 1H-NMR, 13C-NMR, IR and elemental analyses. The configurations of some of these mono-spiro-β-lactams were established by X-ray crystal analysis.
Tunneling time and Hartman effect in a ferromagnetic graphene superlattice
Farhad Sattari,Edris Faizabadi
AIP Advances , 2012, DOI: 10.1063/1.3681190
Abstract: Using transfer-matrix and stationary phase methods, we study the tunneling time (group delay time) in a ferromagnetic monolayer graphene superlattice. The system we peruse consists of a sequence of rectangular barriers and wells, which can be realized by putting a series of electronic gates on the top of ferromagnetic graphene. The magnetization in the two ferromagnetic layers is aligned parallel. We find out that the tunneling time for normal incident is independent of spin state of electron as well as the barrier height and electron Fermi energy while for the oblique incident angles the tunneling time depends on the spin state of electron and has an oscillatory behavior. Also the effect of barrier width on tunneling time is also investigated and shown that, for normal incident, the Hartman effect disappears in a ferromagnetic graphene superlattice but it appears for oblique incident angles when the x component of the electron wave vector in the barrier is imaginary.
OH Masers and the Dust Emissions Towards High Mass Protostellar Objects

Physics , 2011,
Abstract: Context: OH maser emission is known to be associated with high mass star forming regions. Towards some of these regions, OH masers are associated with HII regions. Towards others, believed to be in an earlier evolutionary state, OH masers are offset from HII regions. Towards these later regions, it is believed that OH masers are associated with the circumstellar disk (e.g. Edris et al. 2005; Gray et al. 2003). These disks should be hosting dense dust grains. The presence of the hot dust could be traced via the millimeter continuum emission as well as IR emission. Aims: studying the association between millimeter (mm) continuum, the OH masers emission, and IRAS sources. Methods: A sample of 27 High Mass Star Forming Regions (HMSFRs) chosen from IRAS catalog and show OH maser emission (Edris et. al. 2007) have been studied at 1.1 millimeter (mm) continuum emission of the Bolocam Galactic Plane Survey (BGPS). Results: The 1.1-mm continuum emission have been found within ~ 30' towards 23 sources of the OH maser sample. These sources were divided into three groups depends on the offset of the closest mm peak from the OH maser position. The association between the OH, mm and IR emissions types have been confirmed for two sources. Generally the IRAS position is more consistent with the mm peaks than the OH maser emission and towards 10 sources the IRAS and OH masers are not consistent with the same mm peak. Conclusion: The relatively large positional uncertainty do not allow to firm conclusions but it seems that the IR peak is closer to the mm emission than the OH maser.
A New Approach for Converting Renewable Energy to Stable Energy  [PDF]

Abstract: A renewable energy plant which relies on wind speed or solar insolation is unreliable because of the stochastic nature of weather patterns. It is theorized that by using multiple renewable energy plants in separate areas of a region, the different weather conditions might approach a probabilistically independent relationship. The goal of this paper is to utilize the power system technology to help disseminate wind and solar power systems to get a stable energy. A new approach to get appropriate stable energy is achieved by using the interrupted energy that obtained from wind farm and solar insolation. This is achieved by lifting water to a higher level with appropriate pumps and storing it in the form of potential energy. Then a stable energy is obtained by reliving water to the lower level. In this paper, the efficiency obtained from the renewable energy is compared with that obtained from traditional ones. An experimental model to simulate the process of converting the renewable energy to a stable energy is presented. The obtained results from experimental model explained that the renewable energy can be converted to a stable one with high efficiency.
