Renewable and Sustainable Energy Reviews | Year: 2010

Renewable energy resources have played an important role to meet increasing energy demand in the world. Among the renewable energy resources, especially, wind energy is of interest due to some advantages, such as being clean, environmental friendly etc. However, the intermittent nature of wind creates several problems to the power system operation and new approaches based on the combined use of wind power and energy storage technologies need to be developed. One of these combined systems is wind-hydro pumped storage systems. In this paper, hydropower and wind energy potential of Turkey are investigated in details. Besides, the importance and the necessity of wind-hydro pumped storage systems for Turkey are comprehensively examined and finally, the contribution of wind-hydro pumped storage systems is emphasized in meeting Turkey's electric energy demand.

Approximately, 20% of the electricity consumed in the world is spent for lighting. More efficient utilization of the sun, as a natural source of light, for lighting would save electricity used for lighting. The aim of this study is to illuminate a windowless room via a light-pipe and dimmable electronic ballasts. Light-pipe is used for the illumination of the space during the daytime. In case of inadequate daylight, artificial lighting is made via dimmable electronic ballasts and fluorescence lamps. Artificial lighting is supervised by a fuzzy logic control system to keep the illumination level at 350 lux. When there is a motion in the room, the system works with the message of the motion sensor, which, thereby, enables energy saving. Additionally, dimming the lamps result in conversation of the electrical energy used for illumination. After the experimental studies, 350 lux value targeted in the work plane is achieved with ±10 lux error. © 2013 Elsevier B.V. Source

In this study, the modified finite element-transfer matrix methods are proposed for free vibration analysis of asymmetric structures, the bearing system of which consists of shear wall-frames. In the study, a multi-storey structure is divided into as many elements as the number of storeys and storey masses are influenced as separated at alignments of storeys. The shear walls and frames are assumed to be flexural and shear cantilever beam structures. The storey stiffness matrix is obtained by formulating the governing equation at the center of mass for the shear walls and the frames in the i.th floor. The system transfer matrix is constructed in the dimension of 6×6 by transforming the obtained stiffness matrix. Thus, the dimension, which is 12n×12n in classical finite elements, is reduced to the dimension of 6×6. To study the suitability of the method, the results are assessed by solving two examples taken from the literature. Source

Objectives: The aim of this article was to determine risk factors for postpartum depression in low-socioeconomic level women during the first postpartum year and to determine the relationship between postpartum depression symptoms and social support. Methods: This is a cross-sectional study. Data were collected through administration of a questionnaire, the Edinburgh Postnatal Depression Scale (EPDS) and the Multidimensional Scale of Perceived Social Support (MSPSS). Data were analyzed utilizing unpaired t test, one-way analysis of variance, and logistic regression analysis. Results: The prevalence of perceived symptoms of postpartum depression was 21.0% (scores of C13) and there was a correlation (r = -0.36, p = 0.000) between MSPSS and EPDS scores. The mean EPDS score was 8.36 ± 5.6 while the mean MSPSS score was 64.49 ± 15.2. Conclusion: Postpartum depression symptoms are common among Turkish women. These findings provide important information about the role of social support related to postpartum depressive symptoms among Turkish women. Informing health professionals about these issues is an important step towards improving maternal and child health care services. © Swiss School of Public Health 2010. Source

Concentrations of 210Po were determined in the edible muscle tissue of five species of marine fish: Sardine (Sardine plichardus) and Anchovy (Engraulis encrasicolus), Red mullet (Mullus barbatus), Horse mackerel (Trachurus trachurus) and Gilt-head sea bream (Sparus aurata) collected from five stations in the Aegean Sea Region of Turkey during the fishery season 2010. The 210Po concentrations in the fish samples were found to vary from not detected levels to 389 ± 45 Bq kg-1 dry wt. These variations in 210Po content in different species are probably due to differences in metabolism and feeding patterns. The highest levels for 210Po were observed in Anchovy (E. encrasicolus) species. © 2012 Elsevier Ltd. Source
