Background: Magnetic separation using magnetic nanoparticles can be used as a simple method to isolate desulfurizing bacteria from a biphasic oil/water system. Objectives: Magnetite nanoparticles were applied to coat the surface of Rhodococcus erythropolis IGTS8 and Rhodococcus erythropolis FMF desulfurizing bacterial cells, and the viability and...

The international society focuses on the environment protection and natural energy sources control for the global cooperation against weather change and sustainable growth. The study presents the overview of the water shortage status and the necessity of wastewater reuse facility in military facilities and for the possibility of the introduction, compares the economics by means of cost-benefit ...

BACKGROUND Unsafe reuse of injection equipment in hospitals is an on-going threat to patient safety in many parts of Africa. The extent of this problem is difficult to measure. Standard WHO injection safety assessment protocols used in the 2003 national injection safety assessment in Cameroon are problematic because health workers often behave differently under the observation of visitors. The ...

This paper describes the implementation of a knowledge management tool to capture and reuse the lessons learned from the installation of HVAC equipment. It has been developed as an adjunct to an existing system that uses case-based reasoning to reuse previous HVAC installation specifications and designs. The system described lets engineers recall details of installation and commissioning and op...

Usable life of cleaning solutions in a model heat processing unit was studied by evaluation of the nature and quantity of residue remaining on the surface of the equipment after cleaning. Lipoidal residue was recovered from equipment surfaces by ether rinsing. A surface displacement technique was used to quantify the lipoidal material, which was characterized by gas-liquid chromatographic analy...

The shortage of resources for providing renal replacement makes it essential to reduce revenue costs wherever possible. Assuming that haemodialysis is likely to remain a mainstay of renal replacement, a policy of reusing the expensive disposable dialysers and blood lines could offer substantial cost savings. Such reuse has been shown to be safe and to maintain efficiency, but it must also take ...

This study proposes a general methodology for assessing and estimating the potential reuse of small waste electrical and electronic equipment (sWEEE), focusing on devices classified as domestic appliances. Specific tests for visual inspection, function and safety have been defined for ten different types of household appliances (vacuum cleaner, iron, microwave, toaster, sandwich maker, hand ble...
