Is There Enough Evidence for Osteosarcopenic Obesity as a Distinct Entity? A Critical Literature Review
The co-existence of impaired bone health (osteopenia/osteoporosis), reduced muscle mass and strength (sarcopenia), and increased adiposity (obesity) in middle-aged and older people has been identified in recent studies, leading to a proposal for the existence of “osteosarcopenic obesity” as a distinct entity. Evidence for the pathophysiological overlap of these conditions [...]
Reverse osmosis (RO) membrane desalination driven by wind and solar photovoltaic (PV) energy: State of the art and challenges for large-scale implementation
The use of Reverse Osmosis (RO) desalination has grown considerably in response to water scarcity. Despite steady improvements in efficiency, RO desalination remains an energy-intensive process. Numerous studies focussed on using mature Renewable Energy Sources (RES), such as wind and solar photovoltaic (PV) energy, to drive RO plants on a [...]
Cost contingency modelling for construction projects: Insight from the literature
A review of cost contingency modelling in construction projects is presented to find the application areas and limitations of the existing models to pinpoint the further research gap. Three broader approaches of contingency modelling are found: 1) a data-intensive contingency prediction model without risk analysis, (2) contingency estimation following a [...]
Optimization of Precursor Concentration for the Fabrication of V2O5 Nanorods and their MSM Photodetector on Silicon Substrate
This paper presents the effects of precursor concentration on different properties of the V2O5 nanorods (NRs) grown by using spray pyrolysis technique. The V2O5 NRs with different precursor concentrations of VCl3 such as 0.05 M, 0.10 M, 0.15 M, and 0.20 M were prepared on the silicon (Si) substrates. The structural characteristics of NRs [...]
Biochemical Conversion of Microalgae Biomass into Biofuel
Biofuel production via microalgae is a promising and sustainable alternative to replace the typical fossil fuel that is the main contributor to the global warming. However, for a cost-effective biofuel production, further advanced research is still needed for large-scale operation. This article is a tutorial review on conversion processes of [...]
Estimation of solar radiation of clear sky using non- linear methods case study: Fuerteventura (Spain)
The knowledge of irradiation in a geographical area is very important for multiple areas for the development of the area. Current calculation systems are based on statistical models of measurements of ground stations, or by external radiation calculations by satellite models. In this paper we show another method of calculation, [...]
Low energy, low-tech building design for the extreme cold of antarctica
The purpose of this research was to propose and build a sustainable, low-impact, optimized, modular lodge, to facilitate scientific studies in the Antarctic. Within this unique climate, this paper presents new environmental and sustainable approach for the extreme cold. The Polar Lodge was designed and built with a primary concern [...]
Global warming awareness among the University of Bahrain science students
This study was designed to investigate the awareness regarding global warming among the College of Science students at University of Bahrain. A total of 143 science students were examined using a questionnaire that covered three aspects of global warming including causes, impacts, and solutions. The study included 51, 28, 40 [...]
Modeling and assessment of a thermochemical energy storage using salt hydrates
Several research studies have revealed the potential use of salt hydrates in thermal energy storage applications. These materials dissociate into anhydrous salts and release water vapor when subjected to heat source. The latter salt has the capability to store the energy that was supplied for dehydration upon heating. This thermal [...]
Solar radiation and street temperature as function of street orientation. An analysis of the status quo and simulation of future scenarios towards sustainability in Bahrain
This paper discusses the contribution of street orientation towards the development of a comfortable microclimate for pedestrians in Bahrain. Increasing walkability is a global agenda to address issues such as a) transportation, b) energy consumption, c) health, and d) air pollution, all of which are topics of the sustainability agenda.
