Experimental research to Optimize Process Parameters in Machining of Non Conducting Material with hybrid non conconventional machining

Among all non conventional micro machining, electrochemical discharge machining ECDM is having high quality of material removal rate with zero residual stress. This machining has been accepted as a highly modern technology in micromachining. In this paper an effort has been done on micro drilling of glass using electrochemical discharge machining ECDM . A fixed tool and a step down transformer have been used to support the steady machining to increase the accuracy of work piece. The input parameters used in this experiment are voltage, concentration of electrolyte, enter electrode gap and ratio of area of electrode. MRR has been investigated over the input parameters. Feed rate and electrolyte temperature has been made constant of 3µm sec and 30°c respectively. Taguchi method is used to optimize the effect of the process parameters on MRR. The signal to noise S N ratio and the ANOVA analysis are employed to find the contributions of input parameters.

Descriptive Morphology, Morphometry, Community Structure and Spatial Distribution of Helminth Parasites in the Malayan Box Turtle, Cuora Amboinensis (Chelonia: Bataguridae) From Peninsular Malaysia

Thirty-six wild-caught Cuora amhoinensis from Peninsular Malaysia, comprising adults and juveniles of both sexes, were examined for helminth endoparasites. A total of 11 species (5 nematodes and 6 trematodes) were recovered from various organs, namely, Selpinema octorugatus (small intestine), Falcaustra duyagi (large intestine), Falcaustra sp. 1 (large intestine), Oxyurid larvae sp. 1 (liver), Oxyurid larvae sp. 2 (large intestine), Atractidae sp. (large intestine), Parorientodiscus magnus (large intestine), Digenea sp. 1 (liver), Digenea sp. 2 (large intestine), Polystomoides malayi (urinary bladder), and Polystomoides asiaticus (oral cavity). Seven of these helminths were not previously recorded in C. amboinensis, while 4 species, namely Falcaustra sp. 1, Digenea spp . 1 and 2., and the Atractidae sp. may be new species and geographical records, and require further taxonomic workout. The morphology and morphometry of 4 helminth species, namely, S. octorugatus, F. duyagi, P. magnus and P. malayi were studied in detail. A rigorous redescription of S. octorugatus was done with the aid of SEM and Pepsin-HCL digestion. New information was obtained including the number and arrangement of the buccal ridges, the absence of the lateral papillae, the addition of a fifth post anal papillae and the complex structure of the spicule tip. This study also demonstrated the usefulness of the relative positions of the caudal papillae and derived ratios, in the characterisation of the genus Selpinema. The helminth community structure of C. amboinensis in relation to age, gender and lifestage categories was investigated for the first time. This chelonian had a rich assemblage of helminths (observed richness = 11; expected richness, Cha02 = 9.17), with high diversity (Shannon's index = 0.78) and low evenness (0.36). This supports previous claims that C. amboinensis is vagile in food habits and habitat selection. Two helminths, namely S. octorugatus and F duyagi exhibited high intensity and prevalence, and were designated as core and dominant species, while Falcaustra sp. 1 and Oxyurid sp. 1 were regarded as unsuccessful pioneers. The helminth community structure between the various hosts age, gender and life stage categories were different, and may be attributed to disparate feeding habits and habitat utilisation. Results on the spatial distribution of the helminths found in the alimentary canal of C. amboinensis indicate that the worms are site specific, with a relatively narrow niche width. Further, interspecific competition may not be a prominent factor in determining the habitat restriction of helminths in this turtle host. Significant and positive correlation (Spearman' s rank coefficient = 0.45, P<0.05) was found between the intensity and prevalence of S. octorugatus and the packing density of the mucosal folds in the cranial duodenum. These helminths may actively select this niche, as the close proximity of the mucosal folds arranged in a complex labyrinth provide structural support and added traction, which function to stabilise the attachment interface. The large intestinal nematode (F duyagi), on the contrary, appeared to select its habitat based on physiological rather than morphological cues. It is likely that this luminal feeder is attracted to the prolonged retention of food material in the large intestine, and the presence of particulate digesta and abundant micro-organisms

DPP-IV Inhibitors from natural sources: An alternative approach for treatment and management of diabetes

Diabetes is a chronic metabolic disorder present in almost all countries. According to WHO, T2DM is the World’s fifth leading cause of death. Treatment for T2DM depends on the incretin hormone (GLP-1 &amp; GIP). GLP-1 plays a vital role in the body’s metabolism, such as insulin secretion but DPP-IV enzyme inactivates these incretin hormones. Therefore, it becomes important to identify DPP-IV inhibitors that act as prospective antidiabetic agents. Synthetic inhibitors like vildagliptin, sitagliptin, and saxagliptin are available in the market but they have some undesirable side effects. There are several natural plants as well as products that provide safe and effective medication against diabetes by DPP-IV enzyme inhibitory mechanism. This review summarizes recent advancement of DPP-IV inhibitors from medicinal plants and isolated phytoconstituents including alkaloids, flavonoids, terpenoids, phenol, and stilbenoids which are responsible for the DPP-IV inhibition

RESOURCE OPTIMIZATION FOR IT PROJECTS-- RESOURCE OPTIMIZATION FOR IT PROJECTS--A SUPPLY CHAIN APPROACH

Software service organizations (SSOs) execute Information Technology (IT) projects and provide skilled human resources to client organizations. For a given IT project, a SSO may be required to provide their clients with IT professionals having a specific combination of software and/or hardware and/or managerial skills and with a specific level of expertise in each of those skills. However the actual number of people who meet all the required conditions for an IT project would be small. SSOs aim to achieve a balance between high growth and high utilization; the former requires keeping a pool of available resources to be deployed at growth opportunities. However if this pool becomes too large, utilization suffers, lowering profitability. Thus, the key to IT project execution lies in human resource optimization— putting together the optimal mix of human resources at the correct location at the correct time at the correct price. However, SSOs have not been very successful in this regard, with low utilization ratios being common in the industry. The objective of this study is to provide an optimal human resource management model that maximizes profitability by taking into account factors peculiar to SSOs

Self-Guidance and Self-Focusing of Rippled Electromagnetic Radiation Pulse in High Density Magnetoactive Plasma

Inside the plasma, when an intense rippled electromagnetic radiation pulse experiences self-focusing, one need to taking account of radial expansion in view of charge displacement due to ponderomotive force on electron and variation in the mass of oscillating electron under the influence of relativistic effect due to electromagnetic field. The extraordinary-mode (E-mode) propagation in a magnetoactive plasma, with stationary magnetic field, which is analogous to the wavering magnetic field of the electromagnetic radiation pulse, is the key feature for the self-guided propagation of rippling electromagnetic radiation pulse in magnetoactive plasma. If the condition for ultra-fast volume ionization is achieved, the radiation pulse itself can generate such a stationary magnetic field. It is demonstrated that external magnetic field affects the channels, causing them to bend. These effects cast new light on the phenomena of self-focusing of rippled electromagnetic radiation pulse. They raise the possibility of combining energy from several channels into one. It is found that the magnetic field strongly influences the plasma dynamic behavior and overall propagation of rippled electromagnetic radiation pulse.
