Emotional and Behavioral Problems of Afghan Refugees and War-Zone Adolescents
Reza Rostami,Jalil Babapour-Kheiroddin,Behzad Shalchi,Farzaneh Badinloo
Iranian Journal of Psychiatry , 2009,
Abstract: "nObjective: Wars' stress and violence can have tremendous effects on children's and adolescents' health and general well being; it may result in patterns of bio-psychosocial problems. The goal of this study was to compare emotional and behavioral problems in Afghan refugees and war-zone adolescents. "n Method: One hundred and eighty high school students (90 students in the refugee group and 90 in the war-zone group) in Harat were included in this research. All participants completed the Youth Self-Report (YSR). War zone and refugee adolescents were compared based on their scores on different scales of behavioral and emotional problems. "n Results: War-zone adolescents scored significantly higher on Anxious/Depression, Withdrawn, Somatic Complaints, Attention Problems, and Internalizing Problems scales than refugee adolescents. In this study, no significant difference was found between the two groups on Social Problems, Thought Problems, Delinquent Behavior, Aggressive Behavior, and Externalizing scales. "nConclusion: Findings revealed that although asylum is not an ideal condition for children's and adolescents' psychological development and prosperity, it can have a protective role in comparison with war zone's circumstances. Further investigation is needed, however, to elucidate the lack of significant differences in externalizing scales among war zone and refugee adolescents

Faezeh Farzaneh, Sara Haghshenas
Materials Sciences and Applications (MSA) , 2012, DOI: 10.4236/msa.2012.310102
Abstract: In this study nanoporous NiO was prepared using Ni(CH3COO)2,4H2O, folic acid and water as starting material, template and solvent respectively, by sol gel method followed by calcination at 400℃. The solid product was characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption, scanning electron microscopy (SEM), transmission electron microscopy (TEM) Fourier transform infrared (FT-IR) and photoluminescence (PL) techniques. The particle size of the nanoparticles estimated by XRD was in good agreement with the particle size obtained by TEM analysis (4-5nm). It was also found that the prepared nanoporous NiO show very good activity for photodegredation of dye organic pollutants such as Congo red (91%) during 1.5 hours.
Does Exposure to Noise Lead to Decreased Regulatory Abilities, and Increased Aggression?  [PDF]
Farzaneh Pahlavan, Melana Arouss
Journal of Behavioral and Brain Science (JBBS) , 2016, DOI: 10.4236/jbbs.2016.61007
Abstract: Recent advances in the study of affective-cognitive regulation of aggressive behavior suggest positive correlations between poor executive capacities (ECF) and negative reactivity. If the global assumption is correct what are the likely implications of predicted relation? The central issue in present research is to verify this assumption and examine how situational characteristics can alter executive performance in adults experiencing Civil War (Syrians students living in their country or in a host country) and adults experiencing peaceful life (French students) to explore some of the consequences of those modifications for aggressive and anxious tendencies. Precisely, we expect the positive correlations between poor executive performances and high dispositional as well situational aggressive and anxious tendencies, specifically for adults exposed to warfare. In order to assess executive capacities and dispositional as well as situational aggressive and anxious tendencies, during one pilot and two comparative studies [pilot study: N = 60 female French students; first comparative study: N = 60 French and N = 60 Syrian students of both sexes (50%); second comparative study: N = 60 Syrian students of both sexes (50%) living in France] right-handed French/Arabic-speakers participants complete twice, before and after completion executive tasks (standard neuropsychological tests) under different experimental conditions (Aversive/Neutral condition), a series of aggression and anxiety questionnaires. The results provide evidence of a dispositional relationship between poor executive functioning and negative reactivity, and extend it to situational level. For all participants, it shows that increases in impulsiveness (negative emotionality and aggressive choices) due to an aversive noise (80 db) are concomitant with an inability to focus individuals’ attention on ongoing tasks, specifically in those living directly or indirectly stressful life-event.

International Journal of Hospital Research , 2012,
Abstract: Background and Objectives: Balanced Scorecard is an increasingly popular tool for performance evaluation. Health-care organizations have broadly adopted this method for implementing their strategic plans. There is, however, increas-ing concerns on barriers to balanced scorecard implementation. Built on the fundamental impacts of organizational culture on hospital performance, this study explored the relationship between balanced scorecard effectiveness and organizational culture.Methods: A descriptive analytical study of cross-sectional design was conducted within the period of August 2009 to June 2010. One hundred and fifty employees of Hasheminejad Kidney Center were enrolled. The questionnaire com-prised two items addressing balanced scorecard effectiveness and 60 items related to four dimensions of organizational culture, including Involvement, Consistency, Adaptability, and Mission. Validity of the questionnaire was examined by seeking expert opinion. A high reliability of the questionnaire was ensured by obtaining a Cronbach’s alpha of 0.94. Sur-vey results were summarized using descriptive statistics. The relationship between organizational culture and balanced scorecard effectiveness was measured using Pearson’s correlation coefficient, and modeled via regression analysis.Findings: Balanced scorecard effectiveness showed significant correlations with Involvement (r = 0.44, P < 0.01), Consistency (r = 0.27, P < 0.01), Adaptability (r = 0.28, P < 0.01), and Mission (r = 0.35, P < 0.01). Multiple regression analysis identified Involvement as the only predictor of BSC effectiveness (β = 0.431, P < 0.01).Conclusions: While all factors of organizational culture can influence balanced scorecard effectiveness, employee involvement holds prime importance. Hence, hospital leadership needs to strongly encourage employee involvement in organizational processes, in order to achieve high effectiveness of balanced scorecard.

American Journal of Analytical Chemistry (AJAC) , 2011, DOI: 10.4236/ajac.2011.28103
Abstract: This paper describes a dispersive liquid–liquid microextraction (DLLME) procedure using room temperature ionic liquids (RTILs) coupled with flame atomic absorption spectrometry detection with microsample intro-duction system capable of quantifying trace amounts of lead. In the proposed approach, ammonium pyr-rolidine dithiocarbamate (APDC) was used as a chelating agent and 1-hexyl-3-methylimmidazolium bis (trifluormethylsulfonyl)imid as an extraction solvent was dissolved in acetone as the disperser solvent. The binary solution was then rapidly injected by a syringe into the water sample containing Pb2+ complex. Some factors influencing the extraction efficiency of Pb2+ and its subsequent determination, including extraction and dispersive solvent type, pH of sample solution, concentration of the chelating agent and salt effect were inspected by a full factorial design to identify important parameters and their interactions. Next, a central composite design was applied to obtain the optimum points of the important parameters. Under the optimum conditions, the limit of detection (LOD) was 0.2 µg/L. The relative standard deviation (R.S.D) was 1.4% for 5 µg/L of Pb2+ (n = 7). The relative recovery of lead in seawater, blood, tomato and black tea samples was measured.

International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.35072
Abstract: Background: Constipation is one of the most common problems in the pediatric age group. In the vast majority, chronic constipation is idiopathic or functional. In addition to education and behavioral changes, disimpaction and maintenance treatment with medications are the main pillars of successful outcome. The medications are variably effective and have potential side effects. Objectives: The current clinical trial was designed to evaluate clinical efficacy of polyethylene glycol (PEG) 3350 and liquid paraffin in chronic functional constipation. Besides, subjects were followed carefully for the side effects. Material and Methods: This study was involved 110 children suffering from chronic functional constipation. They were placed into two different groups, randomly. Each group was treated with PEG 3350 or liquid paraffin. The clinical efficacy and side effects were monitored. Results: After disimpaction with bisacodyl suppositories or combined with Mineral oil enemas in hard fecal impaction, maintenance therapy with PEG 3350 or liquid paraffin was started. The treatment duration and efficacies were not different between the two groups. Furthermore, serious adverse drug reaction was not observed. The family history of constipation and presence of incontinence were two worse prognostic factors. Conclusion: No difference was observed between PEG 3350 and liquid paraffin in chronic functional constipation in children in terms of their efficacies. They are safe and effective medications in this age group.

Tehran University Medical Journal , 2008,
Abstract: "n Normal 0 false false false MicrosoftInternetExplorer4 Background: Ewing's sarcoma is one of the most malignant tumors in children and young adults. Only a few established cell lines of Ewing's sarcoma have been reported, which makes it difficult to study the biological features of these tumors. We have recently established a new Ewing's sarcoma cell line designated SS-ES-1, originating from a thoracic tumor of a 16-year-old female patient. The SS-ES-1 cells have been grown continuously in culture for over 90 passages. In this report, some characteristics of SS-ES-1 cells are presented. "n"nMethods: The cells were grown in DMEM medium supplemented with 10% fetal bovine serum (FBS), 100 mg/ml streptomycin and 100 U/ml penicillin in a humidified atmosphere with 7% CO2 at 37 oC. The cells were immunocytochemically characterized using a panel of monoclonal and polyclonal antibodies. Furthermore, the chemo-sensitivity of this cell line to some anticancer drugs was assessed using MTT assay and IC50 values were determined."n"nResults: Morphologically, the SS-ES-1 cell line is composed of poorly differentiated small round cells growing in a multilayer pattern. The immunocytochemical staining demonstrates strong reactivity to CD99, cytokeratin, neurofilament, p53 and Ki67 proteins, but no reactivity to GFAP. Based on IC50 values, SS-ES-1 cells display considerable sensitivity to vinblastine (2±0.7 pM), followed by vincristine (0.3±0.12 nM), doxorubicin (0.05±0.03 μM), etoposide (0.64±0.28 μM) and cisplatin (0.67±0.45 μM)."n"nConclusions: In conclusion, the SS-ES-1 cell line demonstrates unique cellular properties, which make it a useful model for studying various aspects of the biology of Ewing's sarcoma."n"n
Viscoelastic Properties of Polypropylene Reinforced with Mica in and Transition Zones

International Journal of Polymer Science , 2011, DOI: 10.1155/2011/427095
Abstract: The viscoelastic properties of mica-reinforced polypropylene (PP) was studied in temperature range between ?30°C and 120°C. WLF equation permits determining the free volume fraction in and transitions regions. It was shown that the value of this parameter is lower for transition, indicating that the free volume and thermal expansion of region is more than that of region. At a 40% loading level, it was shown that the storage and loss modulus of mica-filled PP increases dramatically (in comparison with the pure polypropylene). The relative modulus does not change significantly at glassy state but it increases for the temperature higher than . It was also shown that mica does not affect the glass transition temperature but results in an increase in transition. 1. Introduction There are several advantages with polypropylene reinforced with mica. This composite has relatively high stiffness, high-dimensional stability, low thermal conductivity, low cost, and so forth The effect of mica on properties of polypropylene especially the mechanical properties was the subject of several studies. In a general way, the mechanical properties of a filled polymer depend on several parameters, the size, aspect ratio, and geometry of the filler, its weight percent, the dispersion of the particles in the matrix, the adhesion between matrix and filler, and so forth. Several authors have studied the effect of rigid fillers like mica on mechanical and dynamic mechanical properties of polypropylene [1–5]. They have shown the filler effect on the properties of this polymer in glassy and rubbery states and more particularly on glass transition temperature [6, 7]. It has been also demonstrated that the effect of fillers on viscoelastic properties of polymers in glassy state and rubbery state is not the same. The mineral fillers do not shift the glass transition temperature of the polymer but this transition zone will be broadened because of the filler particles. It was shown that the mechanism of damping of filled polymers depends on particle-particle friction, particle-polymer friction, and change of polymer properties by adsorption onto filler particles [8]. In the case of semicrystalline polymers, it is well known that beside α transition there is another transition called αc transition ( ) for the temperatures higher than in rubbery state [9]. This transition is mainly related to the crystalline phase. In this case, it is interesting to study the effect of filler on this transition. Unfortunately there is not a significant research work to show this effect on transition of
