A potential degrader of paraffinic and aromatic hydrocarbons was isolated from oil-contaminated soil from steel plant effluent area in Burnpur, India. The strain was investigated for degradation of waste lubricants (waste engine oil and waste transformer oil) that often contain EPA (Environmental Protection Agency, USA) classified priority pollutants and was identified as Ochrobactrum sp. C1 by...

Heavy metals are one of the dreadful environmental pollutants. Its toxicity is a menace to the ecosystem and has attracted global concern over the decades. The attendant uncontrolled disposal and recycling of electronic-waste (e-waste) has greatly influence the elevated concentration of heavy metals observed in Nigeria waterways. This study was carried out to investigate the frequency of the de...

E-waste, a relatively recent addition to the waste stream in the form of discarded electronic and electric equipment, is getting increasing attention from policy makers as the quantity being generated is rising rapidly. One of the most promising policy options to address this issue is to extend the producers responsibility for their products beyond the point of sale, until end-of-product-life. ...

The growth in electrical and electronic equipment (EEE) production and consumption has been exponential in the last two decades. This has been as a result of the rapid changes in equipment features and capabilities, decrease in prices, and the growth in internet use. This creates a large volume of waste stream of obsolete electrical and electronic devices (e-waste) in developed countries. There...

Electronic waste recycling operations in some parts of Asia are conducted using rudimentary techniques which result in workplace and environmental contamination with toxic metals and persistent organic pollutants. This study reports concentrations of 14 polybrominated diphenyl ethers (PBDEs), from tri- to deca-brominated, in 31 samples of soil, sediment, dust or ash collected in the vicinity of...

The ever increasing pile-up of electronic waste in dumping sites, especially in developing countries such as China, Pakistan, India and several African countries, might have caused a significant alteration in the microbial community of the contaminated sites. This change in the microbial population may have significant impact to the soil ecology function. The major pollutants of electronic wast...

conclusions in both itm and modern medicine, ayarij-e-faiqra is a powerful purgative medicine because aloe spp. dried juice is the main ingredient. this juice has been used with other components to increase the efficacy of the medicine and to reduce the adverse effects associated with ayarij-e-faiqra. in itm, purgative medicine expels and eliminates waste humors from body systems. in modern med...

With the increasing innovation of new electronic devices continually entering the marketplace, manufacturers and retailers are seeking partnerships with third party logistics (3PL) providers that can decrease e-waste through reverse logistics for end-of-life devices. With the general public’s sentiment to preserve the environment for future generations, manufacturers and retailers as well as th...

In this paper, we look at the IEEE 802.16e or IEEE 802.16m based MBS and its problem of waste of resource. And we also look at new ways of MBS which have been introduced to overcome the disadvantage of waste of resource. Especially, we closely look at one of the new methods which dynamically configure the MBS region. And then, we show how many base stations are needed to obtain almost the same ...
