Recovering the Power Inside: A Qualitative Study of Critical Reading in an Iranian University
Sue-san Ghahremani Ghajar,Masoumeh Kafshgarsouteh
Turkish Online Journal of Qualitative Inquiry , 2011,
Abstract: A fundamental goal of critical literacy approaches is to bring a change and empower students as critical agents and subjects of decision making. Students are expected to do more than simply accumulate information; they are encouraged to challenge their ‘taken for granted’ belief structures and transform themselves as well as their immediate social environment. In this article, we present a qualitative enquiry in a university reading course based on critical literacy. We explored how learners reflected on their individual/community and word/world concerns through critical understanding of texts and how they challenged and shattered their ‘taken for granted’ beliefs and started to transform into critical agents of voice and position. The data consists of 400 concept maps, called webs, and personal journals by fifty undergraduate English literature students at an Iranian University, as well as oral and written interviews. The data was qualitatively analyzed in search of themes that could illustrate students’ early thinking structures and their empowerment and transformations into subjects of decisions. The study revealed that, through webbing words/worlds and critically challenging texts, students took the opportunity to approach the knowledge and information presented to them analytically and critically. On this basis, we discuss how students were able to gain the power of critiquing, freeing their thoughts, finding and expressing their voice and position, discovering personal meanings in texts and contexts, cooperating and participating, and understanding learning for meaning through the critical act of reading.
The Effect of Television Decors on the Change of Reverberation Time of the Studio  [PDF]
Mohsen Karami, Masoumeh Shafieian
Open Journal of Acoustics (OJA) , 2013, DOI: 10.4236/oja.2013.32005
Abstract: Reverberation time within studios decor is changed because of addition of its surface to the overall surfaces of the studio and also the additional absorption of its materials. It seems reverberation time changes due to studios decor is little because surface of the decor is small in comparison with the overall surfaces of the studio and surface has an important role in room constant and therefore in reverberation time. But these changes do not only depend on added surfaces and their absorption. Reverberation time is also dependent on shape of the decor and sometimes. It can decrease the effects of added surfaces which are used to increase the reverberation time. In this paper, a standard television studio is designed and implemented by using ODEON and 12 different decor which their dimensions and materials are similar to the actual ones, are applied inside the studio. Then studios decor effects on reverberation time of the studio are computed, compared and analyzed.

Abstract: {[Cu(pydc)(amp)].3H2O}n has been hydrothermally synthesized and characterized by elemental analysis and by IR spectroscopy. A wide range of hydrogen bonds (of the O-H...O, N-H...O and N-H...N type) are present in the crystal structure. Hydrogen bond interactions between the co-crystallized water molecules led to formation of six-membered rings with chair conformation.In {[Cu(pydc)(amp)].3H2O}n, there are three uncoordinated water molecules. Thermal methods confirm number of co-crystallized water molecules in polymer. Hydrogen bond interactions between the co-crystallized water molecules led to the formation of a six-membered ring with the chair conformation. These rings are part of a 1D chain containing six-membered O6 rings, which are alternately made from (H2O)6 and [(H2O)4O2] rings. [(H2O)4O2] rings are also in chair conformation.Water is nature's solvent and plays a fundamental role in biological and chemical processes. It is the most abundant and cheapest solvent available for the development of new reagents and the study of chemical processes [1]. Understanding of the behavior of water clusters are important and structural information of small water clusters is the first step towards the understanding of the behavior of bulk water [2]. An extensive investigation of small and medium sized water cluster (H2O)n (n = 2-100) structures have been reported in recent years [3,4]. Various water clusters including pentamers [5,6], hexamers [6-8], heptamers [9-11], octamers [6,8,12,13], decamers [6,14-16] and 1D or 2D infinite water chains [2,17,18] in a number of organic and inorganic-organic hybrid hosts, have been structurally characterized. Recently, we also reported a tetrameric water cluster rings in the crystal structure of a new proton transfer system derived from pyridine-2,6-dicarboxylic acid and 2-amino-4-methylpyridine [19]. Several different conformations for the water hexamer, such as all-boat [20], all chairs or an intermediate between chair and boat [3,21
(2-Aminopyrimidine-κN1)diaqua(pyridine-2,6-dicarboxylato-κ3O2,N,O6)nickel(II) monohydrate

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810016843
Abstract: The reaction of Ni(NO3)2·6H2O with pyridine-2,6-dicarboxylic acid, NaOH and 2-aminopyrimidine in aqueous solution leads to the formation of the title complex, [Ni(C7H3NO4)(C4H5N3)(H2O)2]·H2O. The NiII ion is coordinated by one N and two O atoms of the tridentate chelating pyridine-2,6-dicarboxylate anion, one heterocyclic N atom of the 2-aminopyrimidine ligand, and two water molecules. The resulting geometry for the [NiN2O4] coordination environment can be described as distorted octahedral. One uncoordinated water molecule completes the asymmetric unit. Extensive O—H...O and N—H...O hydrogen-bonding interactions between the NH2 group of 2-aminopyrimidine, carboxylate groups, and coordinated and uncoordinated water molecules contribute to the formation of a three-dimensional supramolecular structure.

Behbood , 2011,
Abstract: Background: Dysmenorrhea occurred in about fifty percent of women with regular menstruation. Different methods were applied for treatment and medications with lower side effects are preferred. Aim of this study was to detect the effect of echinophora-platyloba on primary dysmenorrhea in students.Methods: This single blind clinical trial was carried out in single students with primary dysmenorrhea in the Shahrekord University of Medical Sciences. Sixty students were randomly divided into two groups receiving; the echinophora-platyloba extracts or placebo. Visual analogue scale was used to detect the severity of desmenorrhea. At the end of first and second month after intervention, the severity of pain was assessed and compared with before intervention. Data was analyzed by SPSS software using chi-square, t and mann-whitney tests and P<0.05 considered significant.Results: There was no significant difference between total score of dysmenorrhea before and after intervention (34.74±10.86 vs. 35.55±11.16) in echinophora-platyloba and placebo groups. There was a significant decrease in echinophora-platyloba group (22.49±7.33) compare to the placebo (28.93±9.91) after two-month intervention (P<0.001).Conclusion: Echinophora-platyloba extract reduced the severity of dysmenorrhea. Administration of echinophora-platyloba is recommended to reduce of dysmenorrhea in the students.
El hejab (pa oleta islámica) en el Irán actual: una visión de las mujeres respecto a su uso

Economía, sociedad y territorio , 2001,
Abstract: El trabajo examina las diferentes formas en que las mujeres iraníes perciben y usan el hejab, enfatizando en el hecho de que los significados otorgados al mismo son complejos y contradictorios tanto para las mujeres que lo usan como para las que no, y juega papeles diferentes según los contextos. En el artículo se hace una comparación entre el uso del hejab antes, durante y después de la Revolución Islámica, y se contrasta la literatura escrita por feministas musulmanas con las percepciones de algunas informantes. El trabajo concluye que el hejab obligatorio es una herramienta patriarcal usada por los hombres para controlar a las mujeres, mientras que el hejab voluntario es una herramienta usada por las mujeres para liberarse a sí mismas de las ataduras patriarcales y culturales y para legitimar su presencia en la vida pública, al tiempo que conservan sus tradiciones culturales.
Multiple Functions of the P75 Neurotrophin Receptor in the Nervous System
Masoumeh Firouzi
Zahedan Journal of Research in Medical Sciences , 2012,
Abstract: Background: The P75 neurotrophin receptor (p75NTR) is a transmembrane protein that binds the nerve growth factor (NGF) and implements multiple functions in the nervous system. It is expressed widely during the development of the nervous system although its expression is dramatically decreased at adulthood. Though the P75 neurotrophin receptor has been identified more than 35 years ago, our knowledge about its structure and function has barely increased. Materials and Methods: In this review various methods are used to search databases and reliable scientific resources have been reviewed to give an up-to-date panoramic picture of the protein expression, structure, function, and its interaction with other known molecules.Results: P75NTR not only in neurons but also in various types of glial cells is expressed. In addition to NGF, this receptor can also bind the tropomyosin kinase receptors. Some pathological conditions such as neurodegenerative diseases and nerve damages are followed by the considerable increased expression of p75NTR.Conclusion: In this study, the role of p75NTR in the nervous system of human beings has been investigated and it has been illustrated that how spinal cord repair can improve by blocking of p75NTR. It seems that in addition to p75NTR, someother homologues are also involved in this pathway. Further studies are required to elucidate more details about the role of p75NTR in the development and function of the nervous system.

International Journal of Computer Science Issues , 2011,
Abstract: Content Based Image Retrieval (CBIR) includes a set of methods for processing visual features of a query image to find similar images at an images database. As extracting features and determining similarity measure, are two main stages in retrieval systems. In this paper we have tried to give weight to image pixels and suggest an effective feature vector by use of eye physiological structure and annotation issue. Then modify feature components weight and optimize similarity measure by use of information of relative and irrelative images in each feedback. So by means of annotation issue in physiological structure of eye, pixels in center of image are more important and have more effective role in extracted features and also system accuracy will be increased for determining similar images, by means of optimizing similarity measure in each stage. Experiments were done on Corel image database with 5000 images from 30 different groups. In these experiments, accuracy of suggested method was compared to three image retrieval methods based on l*a*b* color histogram, HSV, and fuzzy edge histogram. As the results suggest, high accuracy of proposed method in compare with other methods in this area.
The Impact of Parent Violence on Behavior Children: An Analysis of 185 Fars, Turkish and Lor Children
Masoumeh Ghasemi
Journal of Applied Sciences , 2007,
Abstract: This study examined compare the behaviors of Fars, Lor and Turkish children who were 6 to 18 years of age and exposed to parent violence with an age and ethnically similar sample of children who were not exposed to violence and to compare both exposed and non exposed children to normative samples. Children, age 6 to 18 years, who were exposed to parent violence, exhibit significantly more internalizing, externalizing and total behavior problems than children who were not exposed to parent violence. In addition, the mean internalizing behavior score for boys 6 to 11 years of age as well as girls and boys 12 to 18 years of age of violence parents were not significantly different from the clinical referral norms. Internalizing behaviors of anxiety, withdrawal and depression are consistent with suicidal risk. Present data demonstrate that children who exposed to parent violence have significantly more behavioral problems than the non clinically referred norm children but also, for most children, display significantly fewer problems than the clinically referred children.

Journal of Family and Reproductive Health , 2008,
Abstract: "nAbstract"nObjective: The aim of this study was to determine knowledge and attitude about emergency contraception among women using condom, coitus interruptus and rhythm methods. "nMaterials and methods: Between April and September 2006, 400 women referring to the health centers in Shahrekord, were evaluated. They entered the study if they were using condom, coitus interruptus or rhythm methods. A questionnaire including demographic information, contraceptive method in use, and patients' awareness and attitude/practice about emergency contraception was completed for each participant."nResults: Of the 400 responders, 60.5% were using condom, 38.7% were using coitus interruptus and 0.8% were practicing rhythm method. The awareness was inadequate in 22.5% of women, moderate in 55% and adequate in 22% of them. The attitude of users was positive in more than 70% of them and only 20.5% of women had practiced emergency contraception. The relation of age and job with awareness was significant (P<0.001). A significant relation was considered between the level of education and knowledge of women (P<0.01). The women who had adequate knowledge had practiced the emergency contraception better than those with inadequate knowledge (P<0.001). However, only 27.1% of responders who reported knowing about emergency contraception knew the correct time frame in which emergency contraceptives must be used."nConclusion: There is a critical need to train the women about emergency contraception, emphasizing available methods and correct timing.
