Entropy, Vol. 13, Pages 1595-1610: The Effect of Thermal Radiation on Entropy Generation Due to Micro-Polar Fluid Flow Along a Wavy Surface

02.09.2011 | Chen, Cha’o-Kuang ; Yang, Yue-Tzu ; Chang, Kuei-Hao, Entropy, 2011

In this study, the effect of thermal radiation on micro-polar fluid flow over a wavy surface is studied. The optically thick limit approximation for the radiation flux is assumed. Prandtl’s transposition theorem is used to stretch the ordinary coordinate system in certain directions. The wavy ...

IJERPH, Vol. 8, Pages 3579-3590: Cancer Incidence of 2,4-D Production Workers

02.09.2011 | Carol Burns; Kenneth Bodner; Gerard Swaen; James Collins; Kathy Beard; Marcia Lee, International Journal of Environmental Research and Public Health, 2011

Despite showing no evidence of carcinogenicity in laboratory animals, the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) has been associated with non-Hodgkin lymphoma (NHL) in some human epidemiology studies, albeit inconsistently. We matched an existing cohort of 2,4-D manufacturing employees ...

Energies, Vol. 4, Pages 1336: Retraction: Manivannan, V.; Chennabasappa, M.; Garrett, J. Optimization and Characterization of Lithium Ion Cathode Materials in the System (1 – x – y)LiNi0.8Co0.2O2 • xLi2MnO3 • yLiCoO2. Energies 2010, 3, 847-865.

31.08.2011 | Brietta L. Pike, Energies, 2011

It has been brought to our attention by an official faculty committee at Colorado State University that portions of the data of this article [1] are not derived from experimental activities. In particular, the ICP-AES data in Table 1 for Compound 6, and the cycle data plotted at cycle 15 and ...

Energies, Vol. 4, Pages 1321-1335: Available Resources for Algal Biofuel Development in China

31.08.2011 | Shuhao Huo; Renjie Dong; Zhongming Wang; Changle Pang; Zhenhong Yuan; Shunni Zhu; Li Chen, Energies, 2011

Microalgal biofuel research in China has made noticeable progress, and algae cultivation for biofuel production is considered to be an important contribution to Greenhouse Gas (GHG) mitigation and energy security. In this paper, the algal biofuel potentiality in China was reviewed from the points ...

IJERPH, Vol. 8, Pages 3562-3578: Issues in Assessing Environmental Exposures to Manufactured Nanomaterials

31.08.2011 | Nicholas T. Loux; Yee San Su; Sayed M. Hassan, International Journal of Environmental Research and Public Health, 2011

Manufactured nanomaterials (MNs) are commonly considered to be commercial products possessing at least one dimension in the size range of 10−9 m to 10−7 m. As particles in this size range represent the smaller fraction of colloidal particles characterized by dimensions of 10−9 m to 10−6 m, they ...

IJERPH, Vol. 8, Pages 3553-3561: Determinants of Exposure to Second-Hand Tobacco Smoke (SHS) among Current Non-Smoking In-School Adolescents (aged 11–18 years) in South Africa: Results from the 2008 GYTS Study

31.08.2011 | Karl Peltzer, International Journal of Environmental Research and Public Health, 2011

The aim of this study was to estimate the prevalence and identify correlates of second-hand tobacco smoke (SHS) among 6,412 current non-smoking school-going adolescents (aged 11 to 18 years) in South Africa. A cross-sectional study was carried out in 2008 in South Africa within the framework of ...

Energies, Vol. 4, Pages 1301-1320: Classification of Fundamental Ferroresonance, Single Phase-to-Ground and Wire Breakage Over-Voltages in Isolated Neutral Networks

29.08.2011 | Lin Chen; Qing Yang; Jing Wang; Wenxia Sima; Tao Yuan, Energies, 2011

This paper proposes a simple and effective method for classification of fundamental ferroresonance, single phase-to-ground and wire breakage over-voltages. In isolated neutral networks, power frequency over-voltages due to ferroresonance, single phase-to-ground and wire breakage may exist for a ...

Energies, Vol. 4, Pages 1278-1300: An S-Transform and Support Vector Machine (SVM)-Based Online Method for Diagnosing Broken Strands in Transmission Lines

29.08.2011 | Xingliang Jiang; Yunfeng Xia; Jianlin Hu; Zhijin Zhang; Lichun Shu; Caxin Sun, Energies, 2011

During their long-term outdoor field service, overhead transmission lines will be exposed to strikes by lightning, corrosion by chemical contaminants, ice-shedding, wind vibration of conductors, line galloping, external destructive forces and so on, which will generally cause a series of latent ...

Entropy, Vol. 13, Pages 1584-1594: Local Stability Analysis of a Thermo-Economic Model of a Chambadal-Novikov-Curzon-Ahlborn Heat Engine

29.08.2011 | Marco A. Barranco-Jiménez; Ricardo T. Páez-Hernández; Israel Reyes-Ramírez; Lev Guzmán-Vargas, Entropy, 2011

In this work we present a local stability analysis of the thermo-economic model of an irreversible heat engine working at maximum power conditions. The thermo-economic model is based on the maximization of a benefit function which is defined by the ratio of the power output and the total cost ...

IJERPH, Vol. 8, Pages 3528-3552: Online Social Networking and Addiction—A Review of the Psychological Literature

29.08.2011 | Daria J. Kuss; Mark D. Griffiths, International Journal of Environmental Research and Public Health, 2011

Social Networking Sites (SNSs) are virtual communities where users can create individual public profiles, interact with real-life friends, and meet other people based on shared interests. They are seen as a ‘global consumer phenomenon’ with an exponential rise in usage within the last few years. ...
