Fatma EKICI,Izzet KARA,Erhan EKICI
The Turkish Online Journal of Distance Education , 2012,
Abstract: In this study we present an overview of the undergraduate blended Physics course that has been supported by the Moodle platform. The course that has been applied is a basic physics course for primary student teachers. The aim of Moodle is to create an online learning environment which helps students to have a virtual space where they can share knowledge through different kinds of supervised activities, chats and forums. Students have to enter Moodle and they have participated activities that have been offered by the instructor after the lesson every week. After the study, results have shown that teacher candidates using Moodle processing have positive thoughts about the course. In the study, it has been emphasized views of prospective primary teachers about MOODLE in some subjects of physics. Students are challenged to doing research. Prospective teachers tend to use this method in their professional life; therefore, it is recommend that offering challenging possibilities to them about their using. It is recommended that this application is become widespread in education (especially higher education in Turkey).

Abstract: To obtain the sustainability of social life and to increase resistance to disaster that cause loss of life and properties; it is possible to raise awareness in the community about disaster preparedness and engross to take all the components. Disaster planning is an approach that targets the correct use of resources to decrease negative impacts in the community after the disaster. In Turkey, earthquake losses have an important role in disaster planning. There are two basic approaches for earthquake loss estimation used in disaster planning namely deterministic and probabilistic. Uncertainties of the seismic risk assessment parameters can be generated from ground motion computations, structural inventories and risk methodologies. In this study, uncertainties in the ground motion estimations are investigated. Gebze district that located close to major fault lines at Marmara region, and had significant damage during Kocaeli earthquake (1990), is selected as a study case for the risk assessment scenarios. The uncertainties parameters in ground motion computation that have major effect on the risk assessment are considered as earthquake source, earthquake magnitude and soil parameters. As a result, building damage ratios, loss of life and the need for shelter are computed. The soil amplification effects on the seismic intensity level and damage ratios are emphasized. The earthquake hazard estimation and risk assessment computation were performed utilizing geographic information system based software AFAD-RED. The software combines the scenario based seismic hazard procedure with the existing building inventories and soil data for the risk estimations. As a result, it is concluded that, uncertainties in ground motion computations have important effect on the seismic risk assessment and should be considered in disaster planning process.

Journal of Animal and Veterinary Advances , 2012,
Abstract: Diclofenac Sodium (DS) is a nonsteroidal anti-inflammatory drug used in painful conditions, trauma, dysmenorrhoea, rheumatoid arthritis, degenerative joint disease and ankylosing spondylitis. There is the paucity of the research investigating DS effect on the rat liver in the fetal period. The present study aimed to investigate the possible postnatal effects of DS on the liver tissues of the offspring of rats. DS was administered to pregnant rats for 15 days from the 5th-20th day of pregnancy. After mating day, pregnant female rats were separated into the control and DS treated groups. DS (1 mg kg-1 daily) was injected intraperitoneally to the drug-treated group and physiological saline (1 mL kg-1) to the control group. Liver tissues were collected from pups at the 20th week and paraffin sections were dyed with hematoxylen-eosin. DS caused proliferation of bile ducts, enlargement of periportal area, dilatation of sinusoids and the central vein, parenchymal degeneration and mononuclear cell infiltration. Significant changes between the control and the treated groups were found (p<0.05). However, no significant difference was observed between the sexes in both groups. This study using DS with low dose did not show parenchymal cell death, as a different finding from the previous studies. However, these observations need to be confirmed by further studies using different doses of DS during pregnancy.

Control of Doubly Fed Induction Generator Supplied via Matrix Converter for Wind Energy Conversion System  [PDF]
Zakaria Kara, Kamel Barra
International Journal of Modern Nonlinear Theory and Application (IJMNTA) , 2014, DOI: 10.4236/ijmnta.2014.33012
Abstract:

The present paper deals with the modeling and control of Wind Energy Conversion System WECS based Doubly Fed Induction Generator DFIG using the slip energy recovery principle. The proposed drive system uses a Matrix Converter (MC) to transfer the slip energy of the rotor into the mains instead of using cascaded ac-dc-ac converter whilst the stator side is fixed to the grid. Operation at both sub-synchronous and super-synchronous regions is possible with the proposed drive system. The different level control strategies for maximum power point tracking and active-reactive power are discussed. Simulation results of the proposed doubly fed induction generator drive system show the good performance of the control system strategy for both transient and steadystate conditions.

Fatma Fidan, Ozlem Baysal
Open Journal of Therapy and Rehabilitation (OJTR) , 2014, DOI: 10.4236/ojtr.2014.23018
Abstract: Aim: The aim of this study was to determine the demographical and clinical features of patients with cerebral palsy (CP) attending to our outpatient or inpatient clinics. Materials and Methods: Children admitted to Inonu University Faculty of Medicine Department of Physical Medicine and Rehabilitation outpatient or inpatient clinics, Malatya, Turkey with the diagnosis of CP during the study period were included in the study. Age, sex, etiological factors, clinical classifications, and epidemiological characteristics such as socio-economic status as well as the problems associated with CP were analyzed in all patients. Results: Of the total of 130 patients with mean ages 51.05 ± 36.06 months, 51 were girls and 79 were boys. The most common etiologic risk factors were bleeding and presence of threatened miscarriage in prenatal period; asphyxia, low birth weight and prematurity in perinatal period; and neonatal convulsions and hyperbilirubinemia in the postnatal period. Consanguineous marriage was present in 24.6% of families. In clinical classification it was seen that 45 subjects were spastic quadriplegic (34.6%), 41 were spastic diplegic (31.5%), 15 were dyskynetic (11.5%), 14 were spastic hemiplegic (10.8%), 10 were mixed type (7.7%) and 5 were hypotonic/ataxic (3.8%). Conclusion: Prenatal risk factors constitute the foremost risk factors in CP etiology. CP incidence can be lowered by close follow up of the newborns who has been considered as high risk newborns due to the presence of risk factors during pregnancies or deliveries, and by increasing the number of neonatal intensive care units. Besides, it is important to raise public awareness about consanguinity marriages in our country.

Abstract: Objective: Aerobic exercises are the basic activity on fight against obesity. And obesity is related with metabolic rate. So our study is aimed to investigate the effects of 8 weeks aerobic exercise on basal metabolic rate and physical parameters. Methods: Sedentary women between the ages of 35 - 45 (n = 40) were randomized into control group (CG) (n = 20) and exercise group (EG) (n = 20). EG underwent 8 weeks of aerobic-run-walk exercise training: 3 days a week, 1 hour sessions. The CG was not trained. Basal metabolic rate (BMR), body mass index (BMI), waist-hip ratio (WHR), body fat percentage (BFP), body fat mass (FM) and lean body mass (LBM) were measured for all of the subjects before and after the training program. Results: Mean BMR decreased from 1386 ± 213.6 kcal to 1327 ± 253.7 in CG, and raised from 1308 ± 201.8 to 1409 ± 218.3 kcal in EG. While BMI raised from 31.39 ± 6.15 kg/m2 to 31.51 ± 6.09 kg/m2 in CG, it decreased from 29.62 ± 3.78 kg/m2 to 28.47 ± 3.74 kg/m2 in EG. There was also statistically significant difference in parameters of WHR, BFP, FM and LBM in favour of EG (p < 0.05). Conclusion: After 8 weeks aerobic exercise training program, there was a statistically significant difference in favour of EG in BMR, BMI, BFP, FM, LBM, WHR and weight parameters.
