The separation and utilization of radiotoxic 90Sr from liquid nuclear waste streams generated in the nuclear fuel reprocessing is highly desirable and challenging.Herein, we studied dibenzo-18-cown-6 functionalized chloromethyl-polystyrene (CMPS-DB18C6) resin which displays an excellent affinity toward Sr2+ion adsorption from aqueous solution.Adsor

Slurry erosion is a serious menace in most of the hydro machine components all around the globe.Slurry erosion is accountable for heavy Ciondolo economic losses.However, some counter measures are being taken to mitigate the effect of sand particles passing through hydro-machine parts and research is also underway to improve the component surface by

Magnesium diboride (MgB2) superconductor combines many unique features such as transparency of its grain boundaries to super-current flow, large coherence length, absence of weak links and small anisotropy.Doping is one of the mechanisms for enhancing these features, as well as the superconducting critical temperature, of the compound.During the pr

A case of alopecia areata followed by relapsing polychondritis is Default presented.Similar cases from the literature are reviewed and speculation about the relationship of these diseases is offered.Although Boys hooded tech tee the occurrence of these diseases together could be coincidental, an association seems immunologically plausible.Thus, rel

Natural resource extraction in Africa has been characterised by conflicts between large scale and small scale miners on the one hand and large scale miners and the communities on the other.In some countries such as Sudan, Democratic Republic of Congo, Angola, Mozambique, Sierra Leone and Liberia, natural resources have bred political instability an
