Author: Hawaldar, Rekha Fartiyal, Ram Naresh Yadav
Keyword: Driving Shaft, Driven Shaft, Bearing, Elbow Rod, Supporting Frame and mechanism
Page No: 14-17
Abstract: The main aim of this review paper is to give detail study about the gearless power transmission mechanism at right angle (900) with the help of L-shape rod (EL-BO ROD) of uniform diameter, Dimension (Identical rod). The mechanism is very important defining application in replacement of gear. It is mainly based on the theoretical, analytical and Finite Element Method (or FEA). Figuring of various parameters such as number of pins, material, dimension difference of component, speed and torque. Gearless power transmission for skew shafts minimize the losses, costs and save the time and space. This system countenance the changing in the orientation of shaft during motion which is very interesting and bewitching about this mechanism. Odd pins or links like 3, 5, 7, 9…must be used in this system and each links are fixed in the drilled hole at both ends of the shafts due to which motion is transferred. Functionally the system is very smooth and work effectively with a very minimum amount of power losses.

Author: Mary V Koshy, Thara K Simon* and Teema Joseph
Keyword: Palynological, Acanthaceae and scrophulariaceae.
Page No: 34-40
Abstract: Pollen grains are the microspores inangiosperms, which in acanthaceae and scrophulariaceae varied size from fine to coarse structures and their size can range from 10 to 100 micrometer. As sucrose is considered to serve energy and osmotic for pollen germination, in the present pollen study sucrose based poller germination studies was performed in 20 plant species involved in acanthaceae and scrophulariaceae family. There is remarkable diversity of pollen morphology in various characters such as pollen size, shape, length and width of the pollen tubes identified from the germination study. Morphological characters of pollen grains also can be useful in the studies of plant systematic and palynological characters are used as a tool for diagnosis of a new species.

Page No: 41-48
Abstract: Since 1996, many studies are carried out on Kimberly S Young’s 8 and 20 questionnaires. But there were no primary treatment methods in correcting the prevalence and socio-demographic rates of internet addiction cases. In this study, we hypothesized that yoga is a skilled tool to tackle internet addiction. The aim is to evaluate prevalence rates of internet addiction during the pre-post yoga practices among the school and college going students in Bhopal city of Madhya Pradesh, India. A package of yoga techniques are developed for addressing the internet addict cases. Both quantitative and qualitative analysis is carried out in this paper. A cross sectional sample size of 299 cases comprising of school, college students are selected for our studies. To evaluate the addiction cases, we have used Young’s 20 item questionnaire. Our hypothesis is proved to be significant with‘t’value 71.14 with p value 0.0001. We found 3 categories of prevalence rates viz; shift users from pre yoga 3.2 % to post 92.03% increase, while mild users reduced from 25.91% to 7.90 during pre and post yoga and final category often users from 73.58% to 0% users and there are no severe cases. Based on findings we may conclude that there is a significant reduction in the internet addicts in addicted cases. The present paper’s pre yoga, data are compared with the surwase et al. results where percentage varied from 90 to 99%, mild, normal, moderate cases. A comprehensive study is required to carry out the clinical studies combine with yoga. Key words: Internet addiction, Yoga, prevalence rate. Download PDF


Title: ONE RAISED PRODUCT PRIME LABELING OF SOME CYCLE RELATED GRAPHS
Author: Sunoj B S*, Mathew Varkey T K
Keyword: Graph labeling; product; prime labeling; prime graphs; cycle.
Page No: 49-54
Abstract: One raised product prime labeling of a graph is the labeling of the vertices with {1,2---,p} and the edges with product of the labels of the incident vertices plus 1. The greatest common incidence num ber of a vertex (gcin) of degree greater than one is defined as the greatest common divisor of the labels of the incident edges. If the gcin of each vertex of degree greater than one is one, then the graph admits one raised product prime labeling. Here we investigated some cycle related graphs for one raised product prime labeling. Keywords: Graph labeling; product; prime labeling; prime graphs; cycle. Download PDF


Title: DEVELOPMENT AND EVALUATION OF SUSTAINED RELEASE TABLETS FOR HIGHLY WATER SOLUBLE DRUG

Page No: 49-56
Abstract: Sustained release tablets reduce the frequency of the dosing and increase the effectiveness of the drug by localization at the site of action, providing uniform drug delivery. Verapamil hydrochloride was considered as an ideal drug for designing sustained release formulation because of the high frequency of administration and short biological half-life. Therefore, in the present study, sustained release tablets of verapamil hydrochloride were prepared by using synthetic hydrocolloids like HPMC K4M, K15M, and K100M and using interaction of natural gums like carrrageenan and chitosan. Before using carrrageenan and chitosan an attempt was made to study the mechanism of interaction of carrageenan and chitosan by FT-IR spectroscopy, x-ray diffraction spectroscopy and differential scanning calorimetry. Then these prepared tablets were evaluated for various parameters such as hardness, friability, thickness, weight variation and the formulations were found to be within limits. The in vitro drug release profile of the various formulations was performed. In pH 1.2 buffer Peppas model was found to be the best fit model of drug release and a better control on drug release can be obtained by varying the proportion of HPMC K4M, K15M and K100M. Hence, it was concluded that the drug release can be effectively controlled for a highly water soluble drug verapamil HCI using synthetic hydrocolloids and interaction of natural gums carrageenan and chitosan.

Title: CONTRAST MEDIA USED IN COMPUTED TOMOGRAPHY
Author: Pankaj Yadav*, Ashok Yadav, Prathibha Yadav, Akash Yadav
Keyword: Contrast media (CM), Computed Tomography, Radiocontrast Agents, Magnetic resonance imaging (MRI)
Page No: 14-19
Abstract: Contrast media (CM) are used in imaging techniques to enhance the differences between body tissues on images. The ideal contrast medium should attain a very high concentration in the tissues without p roducing any adverse effects. Unfortunately, this has not been possible so far and all CM have adverse effects. The increasing use of CM is likely to give rise to a wide range of pitfalls, including compliance with and appropriateness of indications for the use of CM themselves, the choice of the ‘best’ contrast agent, off-label use, evaluation of special populations of patients. Even more prominently it is the issue of informed consent which brings with it a duty to inform patients awaiting the administration of CM with regard to the nature of the procedure, the existence of alternative procedures, the extent of the risks relating to the use of CM and, finally, the risks relating to refusal of the procedure. All these issues may give rise to concerns about liability for failure to offer adequate information to patients or to carefully evaluate and balance the potential risks and benefits of the procedure or, finally, for being unprepared in the event of adverse reactions to CM, especially when these are severe and life-threatening. Educational and training programmes for radiologists are likely to shape change in the medical liability environment in the coming years.

Page No: 20-31
Abstract: Ultrasonography lacked substances to be administered to patients to improve or increase the diagnostic yield, which is peculiar considering that contrast agents have long been used with all the other imaging techniques. Fortunately some contrast agents, most of them consisting in gas microbubbles, have been recently introduced for ultrasound imaging too: this review will focus on their history, behavior, current applications and future developments. No definitive conclusions can be drawn yet on the actual merits of each contrast agent, but all of them seem to be both effective and safe, meaning that their future success will depend on the relative cost-effectiveness and peculiarities.
