Bioactive molecules have been documented since ages in providing medicinal benefits towards various ailments. Recent advances in biotechnological methods have expanded the use of naturally derived bioactive molecules in diverse applications apart from pharma. The demand of better and more potent molecules require continuous exploration of biota from different parts of the world. The environmental conditions do have an impact on not only the quantity but also the potency of bioactive molecules. Arid regions have a peculiar environment where plants need a more robust self-defense system for survival. Such regions hold a promising array of bioactive molecules. There have been reports of some very interesting bioactive molecules from the Middle East. Oman is one such country that harbors huge unexplored species of flora and fauna. The country is abundantly rich in the marine, plant, microbial and animal ecosystems, with over 250 species of medicinal plants. This review provides collective information of the bioactive/phytoconstituent molecules reported so far in Oman from the plants, marine and other plant associated sources. Page(s): 12-16

The physico-chemical parameters like pH, alkalinity, TDS, hardness, Mg2+, Ca2+ etc of Kukkarahalli lake water were studied and the results obtained by the analysis were compared with WHO and ISI standards. The results of the present study are not very encouraging and reflect the deteriorating status of the lake. It emphasises for a quick action to be taken for its restoration. This requires a careful monitoring of lake water by conducting its analysis on a routine basis. This study may be very helpful for the authorities to protect the lake water resources and keep their impurity level under check so that it can be used during the crisis. The study will also help in bringing awareness among the people living near the lakes to keep their environment clean and green. Page(s): 17-20

Rauvolfia serpentina Benth. (of Apocynaceae) commonly known as Sarpagandha is one of the most valuable medicinal plants in Indian system of medicine. No information is available on seed morphology, dormancy and seed storage behavior of the species which is required for conserving the seeds in seed banks. Therefore, an experiment was conducted with seed collected from Sushila Tiwari Herbal Garden, Rishikesh, Uttarakhand, India. Studies were conducted on seed germinability (using germination tests) and seed viability (using topographical tetrazolium chloride test) in relation to desiccation and chilling tolerance using a factorial combination of four moisture contents (5, 7, 10 and 12% moisture content in seeds on fresh weight basis), three storage temperatures (seeds stored in ambient condition, at 15°C and at –20°C) and five storage periods (0, 3, 6, 9 and 12 months). Perusal of data revealed that no significant loss in germination was observed in seeds with 7% and 10% moisture content under ambient as well as other storage conditions, suggesting that seeds of Rauvolfia serpentina are desiccation as well as chilling tolerant and exhibited orthodox seed storage behavior. The seeds are ideal for ex- situ conservation in seed banks/ gene banks for a longer period. Page(s): 21-24

The family plays a crucial role in child development, but the number of single parent family has increased greatly in recent years, children with single parent families are more prone to behavioral problems so growing up in a single parent family puts children at risk. The present empirical study conducted in Mysuru city and the sample of 50 adolescents and single parents were taken for the study. Page(s): 25-27

Conveyor pulley is widely used in the area of material handling equipment field. Pulley is heart of the bulk mining material handling. The main components of conveyor pulley are shaft, drum or shell, end disk or diaphragm plates, locking elements, end disk, lagging and bearing assemblies. Since the stresses and deflections of its parts are depends on each other, an analysis of pulley assembly is mandatory for reliable pulley design. Designing pulley of this kind requires complex calculations of all belt tensions and loads in static conditions. This work will consider assumptions on load variations around its periphery & along the pulley face-width, axial load, self-weight, dead weight and angular velocity. This paper attempts to analyze steady state design characteristics for required capacity of conveyor pulley. The optimization of the design is done through number of iteration by designing problem parametrically. Page(s): 28-33

Engine life and effectiveness can be improved with effective cooling. The cooling mechanism of the air cooled engine is mostly dependent on the fin design of the cylinder head and block. The heat is conducted through the engine parts and convected to air through the surfaces of the fins. Insufficient removal of heat from engine will lead to high thermal stresses and lower engine efficiency. As the air-cooled engine builds heat, the cooling fins allow the air to move the heat away from the engine. Low rate of heat transfer through cooling fins is the main problem in this type of cooling. In the present work, an attempt is made to optimize the circumferential fins of rectangular and triangular geometrical profile on the basis of temperature distribution. The fin body is modeled using solid works and steady state thermal analysis carried out by Ansys. The results obtained from the Ansys analysis are compared with the experimental outcomes.

code cloning is a current area of research in software systems .To copying the existing code and paste it with or without modification is known as code cloning. Code clone detection techniques concerned with finding of the code fragment that produce the same result. The issue of finding the duplicated code led to different tools that can detect the copied code fragments. In this paper comparative analysis of various code clone detection technique have been done. It has been observed that text based technique can detect only Type 1 clone. Token based technique detect Type1, Type II clone. Tree based approach detect Type1, Type II, Type III clone but it is very difficult to create a syntax tree its complexity is very high. Page(s): 43-47

Anonymous network such as Tor, is used to protect user’s identity and it hides client’s IP address from server through series of routing. The users can authenticate services anonymously by using some credential systems. Since anonymity can give users the license to misbehave, some variants allow the selective deanonymization (or linking) of misbehaving users upon a complaint to a trusted third party. The misbehaving users are collected in the Blacklist. To address this problem, Nymble with client puzzle system is proposed, a system which consist of the following advantages, (1) honest users remain anonymous and their requests unlinkable; (2) a server can complain about a particular anonymous user and gain the ability to blacklist the user for future connections; (3) this blacklisted user’s access remain anonymous before the server complains; and (4) users are aware of their blacklist status before accessing a service. In proposed system, Nymble with client puzzle eliminate the need for Pseudonym Manager and the users can receive nymbles directly from the Nymble Manager and by using nymbles, user is connected with server for accessing the services.

Milk is a pale liquid produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases. Milk contains many other nutrients[1] and the carbohydrate lactose. We checked quality of milk and made comparative study of various buffalo and cow milk samples. In this paper various milk samples were analyzed for Starch and cane sugar and found that buffalo milk results were of higher quality than cow milk. Results of buffalo and cow milk samples were compared to its World Health Organization recommended value. Starch and cane sugar were found absent. Page(s): 59-61

Reinforced earth walls play a critical role in the development of modern infrastructure due to safety, environmental, and economic reasons.This paper gives the cost analysis of the reinforced earth walls with different types of reinforced materials for different heights. Retaining walls as earth structures are frequently constructed for a variety of applications, most common being bridge abutments and road construction.When selecting a retaining wall type, mechanically stabilized earth (MSE) walls should always be considered. MSE walls are composed of reinforcing elements, e.g. geo synthetics in the soil fill to resist lateral earth pressures. The use of geo grids or geotextiles rather than metallic strips (ties) is a further development of the Reinforced Earth concept. Geo synthetics offer a variable and often economical alternative to metallic reinforcements for both permanent and temporary walls, especially under certain environmental conditions. Page(s): 68-74

Understanding financial risk tolerance and determining an individual’s willingness and capacity to take on risk is an essential part of financial and indeed economic planning. Increasingly planners draw on the behavioral economics literature. Determining a client’s financial risk tolerance is a crucial part of the investment management process. In assessing the risk profile of a system or individual, it is generally seen that there are four main inputs (1) goals, (2) time horizon (3) financial stability, and (4) risk tolerance (Garman & Forgue, 1997). The final input, risk tolerance, is one of a more subjective than objective nature and thus is much more difficult to measure. Although countless attempts have been made to come up with a more precise quantitative measure for this final input, there is no one size fits all approach to measuring risk tolerance and such it has attracted a high level of interest among a range of schools of thought worldwide and merits further insight and investigation.
