Energies, Vol. 8, Pages 7582-7592: Performance Comparison between Steam Injected Gas Turbine and Combined Cycle during Frequency Drops

24.07.2015 | Bahrami, Saeed ; Ghaffari, Ali ; Genrup, Magnus ; Thern, Marcus, Energies, 2015

Single-shaft gas turbine and its cycles are sensitive to frequency drops and, therefore, sudden change loads or large frequency dips might affect their stability. This phenomenon is related to the reduction of the air mass flow passing through the machine during the frequency dips, which might ...

Entropy, Vol. 17, Pages 5157-5170: Non-Fourier Heat Transfer with Phonons and Electrons in a Circular Thin Layer Surrounding a Hot Nanodevice

24.07.2015 | Cimmelli, Vito Antonio; Carlomagno, Isabella ; Sellitto, Antonio, Entropy, 2015

A nonlocal model for heat transfer with phonons and electrons is applied to infer the steady-state radial temperature profile in a circular layer surrounding an inner hot component. Such a profile, following by the numerical solution of the heat equation, predicts that the temperature behaves in ...

IJERPH, Vol. 12, Pages 8619-8630: Physico-Chemical and Microbial Analysis of Selected Borehole Water in Mahikeng, South Africa

23.07.2015 | Palamuleni, Lobina ; Akoth, Mercy, International Journal of Environmental Research and Public Health, 2015

Groundwater is generally considered a “safe source” of drinking water because it is abstracted with low microbial load with little need for treatment before drinking. However, groundwater resources are commonly vulnerable to pollution, which may degrade their quality. An assessment of microbial ...

IJERPH, Vol. 12, Pages 8644-8657: Experience of Multisensory Environments in Public Space among People with Visual Impairment

23.07.2015 | Jenkins, Gavin R.; Yuen, Hon K.; Vogtle, Laura K., International Journal of Environmental Research and Public Health, 2015

This qualitative study explored the role of sensory characteristics embedded in the built environment and whether they support or hinder people with visual impairment in their use of public spaces. An online survey link was e-mailed to the presidents and committee members of each state’s chapters ...
