Effect of Particulate Reinforcement on the Mechanical Properties of Al2024-WC MMCs  [PDF]
K. Punith Gowda, J. N. Prakash, Shivashankare Gowda, B. Satish Babu
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2015, DOI: 10.4236/jmmce.2015.36049
Abstract: The present work reveals the study of mechanical properties of Al2024-Tungsten carbide MMCs containing tungsten carbide (WC) particulates. The reinforcing particulates in the Al2024 alloy were varied from 0% to 5% by weight. The vortex method of cast production was employed to fabricate the MMCs, in which the reinforcement was poured into the vortex created by stirring the molten metal by means of a mechanical agitator. The composite so produced was subjected to a series of mechanical tests. The results of this study revealed that as the tungsten carbide particle content was increased, there were significant increases in the ultimate tensile strength, hardness and young’s modulus, compressive strength, accompanied by a reduction in its ductility. An attempt is made in the paper to provide explanations for these phenomena.
Idiopathic Intracranial Hypertension in Sickle Cell Disease: A Paediatric Case Report  [PDF]
Bharath Gowda, Sanjay Sahi
Neuroscience & Medicine (NM) , 2013, DOI: 10.4236/nm.2013.44033

In this article, we present the case of a 12-year-old girl with sickle cell disease (SCD), who presented with the severe headache. She had bilateral 6th cranial nerve palsy and papilloedema. The common sickle cell-related vascular causes of headache were ruled out by neuro-imaging. She then had a lumbar puncture and was diagnosed with idiopathic intracranial hypertension (IIH). This case demonstrates that IIH can affect younger children with SCD and should form a part of differential diagnosis when investigating causes of headache in SCD.

La2O3 Catalyzed Oxidation of Alcohols  [PDF]
Ravikumar R. Gowda, Debashis Chakraborty
International Journal of Organic Chemistry (IJOC) , 2011, DOI: 10.4236/ijoc.2011.12008
Abstract: A variety of aromatic, aliphatic and conjugated alcohols were transformed to the corresponding carboxylic acids and ketones with a quantitative conversion in high yields with 70% t-BuOOH solution is water in the presence of catalytic amounts of La2O3. This method possesses a wide range of capabilities since it can be used with other functional groups which may not tolerate oxidative conditions, involves fairly simple method for work-up, exhibits chemoselectivity and proceeds under ambient conditions. The resulting products are obtained in good yields within reasonable time.
Energy and Throughput Optimized, Cluster Based Hierarchical Routing Algorithm for Heterogeneous Wireless Sensor Networks  [PDF]
Mahanth K Gowda, K. K. Shukla
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2011, DOI: 10.4236/ijcns.2011.45038
Abstract: We propose a novel cluster based distributed routing algorithm in a generalized form for heterogeneous wireless sensor networks. Heterogeneity with respect to number/types of communication interfaces, their data rates and that with respect to energy dissipation model have been exploited for energy and throughput efficiency. The algorithm makes routing assignment optimized for throughput and energy and has a complexity of N/K*logN+k2logk approximately, where N is the number of nodes and k is the number of kcluster heads. Performance experiments confirm the effectiveness of throughput and energy optimizations. The importance of choosing an optimal cluster radius has been shown. The energy consumption in the network scales up well with respect to the network size.
Intra-Scrotal Extra-Testicular Leiomyoma, a Common Mesenchymal Tumor at a Rare Site: Emphasizing the Need for Awareness of Its Occurrence  [PDF]

Open Journal of Pathology (OJPathology) , 2015, DOI: 10.4236/ojpathology.2015.51002
Abstract: Leiomyoma is a benign tumor of smooth muscles. Leiomyoma originating from the scrotum is a rare entity. We report a case of 53-year-old African male who presented with a 3 cm lump in the right side of scrotum. Clinically, it was provisionally diagnosed as sebaceous cyst and was excised. The histopathology showed a leiomyoma. There was no cytological atypia or mitosis. The patient also had squamous papilloma over left gluteal region.
Sustainable water supply systems in India: The role of financial institutions and ethical perspective
Gowda Krishne,Doddaswamy Ravishankar
Spatium , 2011, DOI: 10.2298/spat1124016g
Abstract: Water is a scarce resource and an important basic necessity for the human survival. The quantity of potable water on earth is limited and its availability per person is reducing day by day due to increase in global population and damage to environment. Though water available in nature is free, sizeable investment is needed in order to supply water to the people at their doorsteps with required quality. This paper deals with the role of financial institutions in the balanced distribution of water for the public, the related problems with various regulatory instruments, and ethical perspectives for efficient utilization of this scarce resource through internal control aimed at long term sustainability.
Comparative bioavailability studies of indomethacin from two-controlled release formulations in healthy albino sheep
Gowda D,Shivakumar H
Indian Journal of Pharmaceutical Sciences , 2006,
Abstract: The objective of the study was to obtain the pharmacokinetic data of two controlled release formulations of (75 mg) indomethacin and to compare the relative bioavailability of the test formulation (product B cetostearyl alcohol microspheres) with standard formulation (product A-Microcid SR 75 mg capsule). A single dose randomized (4x2) complete cross over study of the indomethacin (75 mg) was carried out on 8 healthy albino sheep. The study was carried out on two separate occasions with a washout period of 2 weeks. Blood samples were collected at pre-determined time intervals. Plasma indomethacin concentrations and other pharmacokinetic parameters obtained were statistically analyzed. The results of the paired t-test for the comparison of pharmacokinetic data showed that there was no significant variation between the products A and B. Products did not show any significant difference between them with regard to the T max , C max , AUC 0-24 , AUCo-oo, MRT, Ka, Kel , K 1/2 , 3.0 h, 2054 ± 55.78 ng/ml, 9637 ± 132.87 ng h/ml, 9870 ± 129.22 ng h/ml, 4.76 ± 0.10 h, 0.3812 ± 0.002 h -1, 0.2713 ± 0.004 h -1, 2.55 ± 0.03 h -1, respectively for product A and 3.5 h, 1929 ± 20.32 ng/ml, 8343 ± 40.04 ng h/ml, 8617 ± 46.88 ng h/ml, 4.98 ± 0.02 h, 0.3648 ± 0.002 h -1, 0.2427 ± 0.010 h -1, 2.86 ± 0.20 h -1 for product B. From the dissolution studies and in vivo bioavailability studies, it was concluded that the products A and B are bioequivalent.
Preparation and evaluation of waxes/fat microspheres loaded with lithium carbonate for controlled release
Gowda D,Shivakumar H
Indian Journal of Pharmaceutical Sciences , 2007,
Abstract: To minimize the unwanted toxic effects of anti maniac drug lithium carbonate by kinetic control of drug release, it was entrapped into gastro resistant, biodegradable, waxes and fat such as beeswax, cetostearyl alcohol, spermaceti and cetylalcohol microspheres using meltable emulsified dispersion cooling induced solidification technique utilizing a wetting agent. Solid, discrete, reproducible free flowing microspheres were obtained. The yield of the microspheres was up to 90.0%. More than 98.0% of the isolated microspheres were of particle size range 115 to 855 mm. The microspheres had smooth surfaces, with free flowing and good packing properties. Scanning electron microscope confirmed their spherical structures within a size range of 339-355 mm. The drug loaded in waxes and fat microspheres was stable and compatible, as confirmed by DSC and FTIR studies. The release of drug was controlled for more than 8 hours. Intestinal drug release from waxes/ fat microspheres was studied and compared with the releases behavior of commercially available formulation Intalith CR -450. The release kinetics followed different transport mechanisms. The drug release performance was greatly affected by the materials used in microsphere preparations, which allows absorption in the intestinal tract.

Identification of connection in spacecraft images and classifying them for Weather Monitoring
Ramya S Gowda
International Journal of Computer Science & Information Technology , 2010,
Abstract: In this paper we discuss on a system where in automatically the images collected from the spacecraft are identified for the connected images. the satellite images taken consist of not only basic shapes with regular size and shape but also the interconnected irregular shapes which is identified as network. Now the images that are automatically classified are either normal weather patterns or adverse weather patterns developed. An early warning is raised based on the images classification if the tendency of adverse weather system is about to be formed. In order to do this the strong knowledge of angular movement of the clouds, the knowledge about clouds, image processing and Neural Networks techniques are essential. The knowledge about clouds helps in analyzing the image data based on which decision can be taken. The image processing knowledge helps in classifying the images and the Neural Networkstechniques helps in processing the interconnected images of the selected region.Since the cloud formation is arbitrary in nature, identification of clouds as segments in the image has to use the techniques of Neural Networks
