Rhodamine B dye (RB) has been introduced into the mesoporous silica (SBA15) and Ag anchored mesoporous silica by applying solution impregnation method. Surface treatment of SBA15 with 3-aminopropyltrimethoxysilane (APTMS) facilitates selective anchoring of the RB molecules on SBA15. The photoluminescence spectra of RB confined within SBA15 indicates higher emission intensity, than that of the RB solid, particularly in the presence of Ag nanoparticles. The significant enhancement in photoluminescence intensity is attributed to the local enhancement of the optical fields near the molecules by interactions with silver plasmons.

The aim of the present study was to assess the importance of siderophore producing rhizobacteria on the growth of Brassica juncea under chromium stress. Pseudomonas sp. (A4) produced an iron chelating substance siderophores in iron deficient medium. Under chromium stress condition Pseudomonassp. (A4) markedly increased the root and shoot length and also biomass of Brassica juncea as compared to Pseudomonas sp. (A3). This plantgrowth promotion has been related to the microbial production of siderophore.

This study considers aesthetic characteristics by examining fashion style of fashion journalist Anna Wintour. Fashion journalists are specialists who work at fashion media. Especially, Anna Wintour is one of the most famous fashion journalist in the world and fashion icon, who has been editor-in chief of Vogue USA since 1988. For this study, Anna Witour's photograph was collected from 2010 to 2015 on web-sites. After collecting images, it analysed with 4criterions which were silhouette, color, fabric(pattern and texture) and hair style(and accessories) following advance researches analysis about fashion style. The conclusions of this study are as follows. First, symbolism revealed that could express her identity through utilizing steady items such as blond bob hair, Chanel bold sunglasses, short round neckless and Manolo Blahnik's low-heeled slingback nude sandals. Especially, she gave consistency to her fashion style with fixed hair style and accessories which are similar in shape. Second, femininity, that reveal as an internal characteristic such as sensitivity and as an external characteristic like fluidity. Anna Wintour expressed femininity with elegant curvy silhouette, various of color and flower pattern. Particularly, she emphasized nature women's body shape with princess silhouette, slim silhouette. Third, analysis result indicated characteristic of authority with oversize silhouette, wide lapel details and glamorous genuine fur items. Furthermore, some of her fur items looked overwhelming which dyed in artificial color or printed with leopard pattern. These powerful items contained immanent meanings that are power and position which could express a role as an editor-in chief of Vogue USA.

This paper gives a brief review of seismicity and seismic monitoring in surface mines. A summary of various researches related to seismicity is presented. Our research focuses on the understanding of seismicity and the application of analytical techniques to seismicity. Seismic monitoring plays an important role in the identification of potential failure planes and thereby predict potential failures. Much of the instrumentation used in our research is derived from earthquake monitoring systems. The major aspects in seismic monitoring are an instrumentation used, size of the network and data acquisition systems. Seismic monitoring in surface mines could be successfully applied to the improvement of safety standards in slope stability.

An efficient mine management system demand constant attention of mine managers on the key performance indicators like production targets, equipment status, condition of haul roads, safety etc.. There is a wealth of information generated during day to day working of the mine. The success of a mining enterprise is a function of reliability of accumulated information and decision making on the basis of such information. In the present paper a computerized mine operations management system developed for a large opencast mine making use of the potential benefits of geographical information systems, real time kinematic global positioning systems and a communication network to improve the overall efficiency of the mine is presented.

The plant growth promoting rhizobacteria (PGPR), Pseudomonas sp. (A3) and Bacillus sp. (AT33) were isolated from the rhizosphere of Amaranthus blitum collected from soil contaminated with chromium. Bothbacterial strains quantitatively reduced hexavalent chromium to trivalent chromium. Pseudomonas sp. broughter greater conversion of Cr6+ in the medium (100%) as compared to Bacillus sp.(62%). Phaseolus mungo seeds inoculated with Pseudomonas sp. or Bacillus sp. were grown under different concentration of chromium. The monitoredparameters included elongation of shoot and root, fresh weight, dry weight and concentration of chromium in the shoot and root systems. As compared to non inoculated seedlings those inoculated with A3 and AT33 exhibited better growth.

A new two dimensional (2-D) analytical model for the Threshold Voltage on dual material surrounding gate (DMSG) MOSFETs is presented in this paper. The parabolic approximation technique is used to solve the 2-D Poisson equation with suitable boundary conditions. The simple and accurate analytical expression for the threshold voltage and sub-threshold swing is derived. It is seen that short channel effects (SCEs) in this structure is suppressed because of the perceivable step in the surface potential which screens the drain potential. We demonstrate that the proposed model exhibits significantly reduced SCEs, thus make it a more reliable device configuration for high speed wireless communication than the conventional single material surrounding gate (SMSG) MOSFETs.
