A Simple sensitive and rapid spectrophotometric method for the determination of Artesunate is described. The method is based on the reaction of H2O2, generated by the cleavage of endoperoxide linkage of Artesunate and its reaction with potassium iodide to liberate iodine. The liberated iodine bleaches the Violet coloured Thionin reagent to colourless species and is measured at 612nm. The Beer's law is obeyed in the range of 12.0 - 215.0 μg/ml for Artesunate using Thionin reagent. The Sandell's sensitivity, detection limit and quantization limit were also calculated. The optimum reaction conditions and other analytical parameters were evaluated. The proposed method is simple, accurate and easy to apply for routine use.

Mucuna pruriens belongs to the family Papillonaceae. The seeds and leaves of these plants contain a large amount of L-DOPA. L-DOPA (L-3,4-dihydroxyphenylalanine) is one of the most widely used drugs in the treatment of Parkinson disease. Development of an efficient gene transfer method is an absolute requirement for genetically improving Mucuna pruriens and creating plants with more desirable traits. A simple protocol was developed for the Agrobacterium-mediated stable genetic transformation of M. pruriens. Agrobacterium tumefaciens strain EHA 101, containing the vector pCAMBIA1305 and the hptII and GUS plus genes, was used for the gene transfer experiments. Putative transgenic shoots were obtained on medium supplemented with kanamycin (50 mg L-1) and cefotaxime (400 mg L-1). GUS histochemical analysis of the putative transgenic tissues further confirmed the transformation event. Genomic polymerase chain reaction (PCR) analysis was performed to verify the presence of transgenes and their stable integration. Transformation mediated by Agrobacterium in M. pruriens is reported for the first time. © TÜBITAK.

A major step forward in establishing an unprecedented regional regime to develop microsatellite technologies and share and use collected data. The memorandum of understanding to create the Asian Micro-satellite Consortium (AMC) will come into effect on November 18, marking a major step forward in establishing an unprecedented regional regime to develop microsatellite technologies and share and use collected data relating to the environment and natural disasters, etc. The consortium will comprise 16 space agencies and universities from nine Asian nations, including Japan. Microsatellites have rapidly become a major factor in space exploitation, and their advent could spur a revolution comparable to that which followed the launch of humankind's first satellite, Sputnik-1, in 1957. The advantages of microsatellites are multifold: In general, they can be developed within a few years, which is much faster than the 10 years required for some larger satellites; they generally weigh 100 kilograms or less; and they are cheaper to build, costing about one-hundredth the price of large satellites. It is essential for Japan and other Asian nations to create an effective international framework toward the goal of obtaining state-of-the-art satellite bus and sensing technologies and the sharing and use of satellite-collected data, thereby maintaining a global presence in the field--this is the notion that has driven the formation of the AMC. The 16 participating institutions are space agencies, governmental institutes or top-class universities from Bangladesh, Indonesia, Japan, Malaysia, Mongolia, Myanmar, Philippines, Thailand and Vietnam (see list below). Data relating to such fields as natural disasters and the environment are of great value to these disaster-prone nations. They also help tackle the issue of environmental destruction. The AMC is also expected to make it much easier to share and standardize satellite bus and sensing technologies, observational data, and data application methodologies. In the future, the consortium is expected to share and utilize data collected by about 50 microsatellites that the participating nations are planning to launch. These microsatellites will allow the AMC to monitor any given location on the Earth around the clock, therefore making it possible to grasp a variety of situations, including major disasters if one should occur. The standardization of advanced optical sensors and other devices is essential in order to effectively make use of satellite-gathered data. By using drones mounted with such sensors for ground observation in international joint undertakings, it will drastically increase the volume of data gathered and the precision of ground verification. Data verified on the ground would also help researchers make far more accurate satellite-data-based estimates. The resultant effects could be enormous in such areas as disaster preparedness/mitigation, global environment change, promotion of agriculture, forestry, fisheries and mining, and countermeasures against air and marine pollution. The signing ceremony for the consortium will be held on November 18th at Hotel Jen in Manila, Philippines. Yukihiro Takahashi, the professor at Hokkaido University who led the formation of the AMC says "I believe that the consortium will trigger the advanced space utilization with microsatellites not only in Asia but also all over the world including Africa and South America".

Compact multiband cross slot rectangular microstrip patch antenna is introduced in this paper. Here one close ended rectangular slot in ground plane and one cross slot in patch are given to excite different resonant frequencies. The correct probe feed location along with the exact slot position gave the promising result. The proposed antenna meets the requirement of impedance bandwidth, return loss and gain of resonant band for IEEE 802.11a and IEEE 802.11b WLANs application that allocate channels in 2.5GHz and between 5.15 to 5.825 GHz. © 2016 IEEE.

In the present work, an attempt has been made to investigate the strength of bolted fasteners and hybrid fasteners under tensile loading for unfilled, TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). Bolt configurations were chosen as 2, 3 and 4, in order to analyze the effect of number of bolts on the strength aspect. For filled GFRP composites, the volume fractions in the matrix were chosen as 1%, 2% and 3%. The result obtained shows that, the static tensile strength of the GFRP composites increases with increase in number of bolts. Specimens with 4 bolt configurations have shown significantly more absorption of load before failure of the joint. Hybrid fasteners are more sustainable to failure than bolted fasteners. Also it is noticed that, the strength of the composites increases with raise in TiO2 and ZnS fillers content up to 2vol.%. In comparison with TiO2 and ZnS filled composites, it was found that ZnS filled composites bears more load. © 2013 Elsevier Ltd.

One of the distinguished objective of science and technology is providing the scientific relevance to non-scientific approaches. This has open up many new avenues in the field of Research and Developments. One such domain is the quantification of human intelligence and its related qualities. Intelligence may be connected to the main and complex organ of the human body, i.e., brain. Hence this paper is one such attempt to study the function of a brain in the form of quantification of Intelligent Index (Combination of EQ and IQ in a varied proportion) through the computation of Emotional Quotient and Intelligent Quotient using Kmeans clustering technique. © 2016 IEEE.

The main affecting parameter for Delamination of the composites and in turn the failure of composites is the Thrust force. In the present work an attempt has been made in order to investigate the Thrust force generated during drilling of the TiO2 and ZnS filled Glass Fabric Reinforced Polymer Matrix Composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and3%. A plan of experiments, based on the techniques of Taguchi, was performed to acquire data in a controlled way. An L27 orthogonal array and analysis of variance (ANOVA) were employed to investigate the influence of process parameters on the drilling of these composites. Drilling has been conducted on a radial drilling machine. Speed of drilling (S), volume fractions (VF) and drill tool diameter (D) were considered as the varying parameters with three levels. Thrust force has been considered as the output parameter and is been measured in each combination of parameters chosen. Results reveal that, the addition of filler will increase the thrust force developed during drilling. As per ANOVA values, drill tool diameter contributes more towards generation of thrust, followed by speed of drilling. Main Effect plots shows that, contribution of speed towards thrust generation is only upto a certain level of increase in speed. Copyright © 2014, IGI Global.

In the present work an attempt has been made to investigate the bearing strength of the TiO2 and ZnS filled glass fabric reinforced polymer matrix composites (GFRP). The volume fractions in the matrix were chosen as 1, 2 and 3%. Single-hole-pin-loaded specimens of each composite material were tested in tension. The result showed that the bearing strength of the glass fabric reinforced polymer matrix composites joints is associated with the filler content and the geometrical parameters. The increase of the filler content in the matrix has increased the bearing strength of the composites. The height bearing strength was obtained in case of composites with 2 volume% of filler content, and it was found that ZnS filled composites bears more load than the TiO2 filled composites. © The Author(s) 2012 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Online handwriting recognition systems have been developed for various character sets. Despite that, very less attempt has been made to build an online handwriting recognition system for Indian languages. We present an online handwritten isolated character recognition system for an Indian language, Hindi, for mobile devices. Developing an online handwriting recognition system for Hindi character set to mobile devices would play an important role in making these devices available and usable for the Indian society. In this paper, we present a model for writer-independent online handwriting character recognition for the 49 basic Hindi characters. The proposed system is implemented on mobile device using two different approaches namely Principal Component Analysis (PCA) and Dynamic Time Wrapping (DTW). To find the suitability of these two approaches for handheld devices several experiments were conducted and detailed analysis has been made on the obtained results. The results obtained for PCA approach is quite promising than DTW. On an average, recognition accuracy up to 86% is achieved for the PCA approach and up to 66% is achieved for DTW approach, also the time taken for recognition of unknown character is around 0.8sec for PCA approach, and around 51sec for DTW approach, thus the PCA approach is suitable for real-time applications. © 2012 ACM.
