Background: Pharmaceuticals, like antiepileptic drugs, are found regularly in surface waters, and consequently, advanced waste water treatment technologies are discussed for substance elimination. Because antiepileptic drugs have shown to transform to more toxic substances, their behavior in these treatment processes and resulting effects on ecotoxicity should be investigated. To validate if wa...

The traditional routing protocols for delay tolerant networks (DTN) usually take the strategy of spreading multiple copies of one message to the networks. When one copy reaches destination, the transmission of other copies not only waste the bandwidth but also deprive other messages of the opportunities for transmission. This paper brings up a mechanism to eliminate the redundant copies. By add...

Six Sigma is a very hot topic in the business world today. Originally developed by Motorola as a metric and methodology for reducing manufacturing defects, Six Sigma is now used to describe a broader array of process improvement methodologies. The focus of Six Sigma is to eliminate waste, redundancy, and error that result from unnecessarily complex or ill defined business processes. Over the pa...

The choice of a site for high and intermediate level nuclear waste product material disposal in Jordan requires careful consideration of hydrology, hydrogeology, geological materials, seismicity, climate and other geological factors. The purpose of this paper is to explore how these factors in Jordan may affect the ultimate decision on where to site such a facility. Taking these factors into co...

The separation membrane techniques in which an external electric field is applied as a driving force (such as electrodialysis, electro-electrodialysis, and membrane electrolysis) are shortly described and their application in environment protection is presented. Attention was focused on recovery of valuable chemicals from effluents and waste gases. Examples of new production methods that elimin...

Lean principles were originally developed in industrial operations as a set of tools and practices that managers and workers could use to eliminate waste and inefficiency from production systems—reducing costs, improving quality and reliability, and speeding up cycle times. Toyota Motor pioneered lean practices, and much of their allure today stems from the fact that the phenomenal performance ...

In the cyclic reservation multiple access (CRMA) scheme, nodes reserve slots in each reserve command. Cycles are then generated in sequence, each of which services the reservations made in the corresponding reserve command. Huang et al. [2,3] proposed a reservation scheme, in which nodes are partitioned into regions and slots can be reused in succeeding regions, to reduce access delays due to l...

Radioactive cesium (137Cs) has inevitably become a human concern due to exposure from nuclear power plants and nuclear accident releases. Many efforts have been focused on removing cesium and the remediation of the contaminated environment. In this study, we elucidated the ability of Prussian blue-coated magnetic nanoparticles to eliminate cesium from radioactive contaminated waste. Thus, the o...

A novel method for preparing thin films was investigated for quantifying gallium and iron in plutonium solutions using WDXRF. This technique was developed to eliminate the potential for radioactive liquid to leak into the spectrometer, decrease specimen preparation time, and minimize waste. Samples were cast in μL quantities onto Kapton, and a surfactant was added to disperse the solution unifo...

Polyethylene (PE) is the most common group of thermoplastic polymers due to its low cost and versatile physical properties. PE is blended with polypropylene (PP) to improve physical properties, such as low temperature impact performance. The composition of these blends is important with regard to performance, and the correct mixing of the pure homopolymers (PE and PP) can eliminate the need for...
