Interactions between the MinD and MinE proteins are required for proper placement of the Escherichia coli division septum. The site within MinE that is required for interaction with MinD was mapped by studying the effects of site-directed minE mutations on MinD-MinE interactions in yeast two-hybrid and three-hybrid experiments. This confirmed that the MinE N-terminal domain is responsible for t...
A Tunnel under an In-Pit Mine Waste Dump to Improve Environmental and Landscape Recovery of the Site
By adopting the green mining concept, industry seeks to respond current societal objective of supplying mineral raw materials necessary for economic development while minimising ecological footprint. To accomplish environmental recovery simultaneously with exploitation, as well take advantage mine waste, this study proposes a new solution that includes construction tunnel access area. The devel...
Various mine detection techniques are reviewed with particular emphasis on signal and image processing methods. Based on the target, mines are classified into two types; anti-tank mine (ATM) and anti-personnel mine (APM). Because of the variety of mine types, current mine detection techniques are diversified. The assumption is made that most mine detection techniques consist of sensor, signal p...
In this work, a safe Coal Mine Monitoring system which replaces the traditional coal mine monitoring systems which tend to be wired network systems. This play an important role in coal mine safe production. With continuous enlarging of exploiting areas and extension of depth in coal mine, many laneways become monitoring blind areas, where are lots of hidden dangers. Moreover, it is inconvenient...
Researchers have worked on routing issues for adhoc-networks, VANET’s, and Wireless Sensor Networks in a normal scenario; recently there has been a recent trend towards the study on underground wireless networks and proposals for design and development for Wireless Underground Sensor Networks. This paper highlights the concept of wireless underground sensor network in the coal mine environment,...
?ining waste, processing by-products and mine water discharges pose a serious threat to the environment as in many cases they contain high concentrations of toxic substances. However, may also be valuable resources. The main target current review is comparative study occurrence rare earth elements (REE) mining waste produced from exploitation coal, bauxite, phosphate rock other ore deposits. Co...
Strain is an important parameter for assessing the potential impacts resulting from mine subsidence movements. However, strain resulting from mine subsidence is also one of the most difficult parameters to predict accurately. A number of methods can be used to predict strain, from simple empirical relationships, to more complex statistical approaches. This paper looks at some of these predictio...
Hobert Knox, m.d. (Edin.), m.r.c.s. (Eng.), l.r c.p (Lond ), etc. Part II. Radio-Therapeutics. Tbie first edition of the work of which this book is Vol. II of the second edition, at once made its mark as a work of reference for the practical worker in a branch of therapeutics which is teeming with interest and suggestive of great possibilities. There is a good deal of new matter in this edition...
