INTRODUCTION Safe disposal of TB culture material in which the infectious burden of clinical samples has been greatly amplified is an important challenge in resource-limited settings. The bactericidal capacity of solar cookers has been demonstrated previously for conventional bacteria and contaminated clinical waste. We investigated the use of a simple solar cooker for the sterilization of myco...

The ability to accurately characterize a Photovoltaic (PV) product is critical at every level of system development. The characterization of systems and devices allows research teams and product development groups to not only map the progress of their own technology but also compare it to that of their competitors. Access to state of the art testing equipment thus allows these teams to make eff...

According to WHO, at any one time, around 50 per cent of medical equipment in lowand middle-income countries cannot be used because of lack of maintenance or spare parts.1 We have found that unwillingness or inability to repair equipment and put it back in use is also a major cause. New equipment is made available by different international non-government organisations (INGOs) competing with on...

Global waste production has raised recently due to numerous agricultural and industrial activities. Among other actions devoted to waste reduction, revaluation seems to be the most advantageous one from an environmental and economic point of view. In the olive oil sector, by-product management (namely olive pomace, olive mill wastewater, and sludge residue) poses serious problems for companies,...

We introduce a paradigm-"hydricity"-that involves the coproduction of hydrogen and electricity from solar thermal energy and their judicious use to enable a sustainable economy. We identify and implement synergistic integrations while improving each of the two individual processes. When the proposed integrated process is operated in a standalone, solely power production mode, the resulting sola...

The wind and solar energy are omnipresent, freely available, and environmental friendly. The wind energy systems may not be technically viable at all sites because of low wind speeds and being more unpredictable than solar energy. The combined utilization of these renewable energy sources are therefore becoming increasingly attractive and are being widely used as alternative of oil-produced ene...

At present time, the SE applied to solar dish reflectors is not competitive compared other concentrated power technologies because Stirling CSP equipment has complex and expensive engines does have a proper energy storage system. This paper introduces technology, proposes layout of simple with compressed air system, examines total performance equipment.

solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23. a statistical analysis was performed to obtain their relationship with sudden storm commencement (sscs) and forbush decrease events (fd) of cosmic ray intensity. an 11-year cyclic variation ...

introduction:                                                                             the erroneous move towards the modern lifestyles has led to uncontrolled population growth, urbanization, disorderly expansion of cities to natural habitats and ecosystems, destruction of traditional rural communities and farm lands, indiscriminate utilization and destruction of natural resources, growth o...
