Moringa oleifera leaves have been reported to be a rich sources of vitamins especially, vitamin A and minerals. They are also an excellent source of nutrients such as vitamin C, zinc, calcium, iron and potassium and phytochemicals which have been shown to have positive health effects. The leaves can be eaten as a vegetable. The leaves cannot be stored more than a week without refrigeration due to its perishable nature. Hence, the leaves can be dried and converted into powder. The powder or dry leaves can be used to enhance the nutritional value of the foods. The present paper thus attempts to develop and standardize new innovative value added product using dried moringa leaves. Among the different drying methods studied blanched and shade dried leaves had better nutrient content. Hence the shade dried leaves were used for standardizing moringa leaf versatile food mix. It was standardized by using grains along with pulses in different variations of moringa leaves. Nutritional properties were analyzed. The standardized moringa leaf versatile food mix contains 6.5 per cent of protein, 6358μg of beta carotene and 4.2 g of iron and hence it will meet the average nutritional requirement of 20 per cent of all age groups. The versatile food mix can be stored in Metalized Poly Propylene (MPP) packages upto 6 months with significant changes in their nutritional properties.Keywords

Grid technologies enable large-scale sharing of resources within formal or informal consortia of individuals and/or institutions: what are sometimes called virtual organizations. In these settings, the discovery, characterization, and monitoring of resources, services, and computations can be challenging due to the considerable diversity ,large numbers, dynamic behavior, and geographical distribution of the entities in which a user might be interested. Authorization and access control; the significant aspects of security, have attracted increased attention in grid computing. In authorization an essential part to protect the information and all other resources from unauthorized access by controlling the access via a particular system. Role-Based Access Control (RBAC) is a fairly novel access control technique that provides a centralized, dynamic, and consistent authorization management specifically for the requirements of a particular industry to improve its security. RBAC was developed in the Globus toolkit(GT). Access control is formed by the support of Community Authorization Service (CAS) and this CAS was used and developed in many problems grid research. The major problem with the CAS is that the user credentials are revealed to the virtual organization (VO).In this paper, analyzes the unique security requirements grid computing and develops a security policy and a corresponding security architecture. We also evaluate the performance of Role Based access control architecture.Keywords

Objectives: Privacy and accuracy are always trade off factors in the field of data publishing. Ideally both the factors are considered critical for data handling. Privacy loss and accuracy loss need to be maintained low as possible for an efficient data handling system. Authors have come up with various data publishing techniques aiming to achieve balance between these 2 factors. Generalization, Bucketization and Slicing are well known techniques among the list. Unfortunately they have their own limitation in handling privacy and accuracy. Generalization suffers in handling high dimensional data thus experiencing higher utility loss. Bucketization lacks data privacy where parting sensitive and quasi identifier attributes is a challenge. Slicing on the other hand though offers better privacy and accuracy, there is always scope to improve data correlation aiming in reducing utility loss. This paper explains a new technique called Slicing+ which handles privacy and accuracy factors effectively. This new slicing+ technique looks promising as it offers flexibility for data publisher to decide on how the data need to published. Data publisher can tune the Slicing+ technique to get data published with better privacy than accuracy or the other way. Algorithms for the two cases are derived and realized usingORANGE tool. This paper explains analysis done for the first bucket tuples. As an improvement aspect, similar analysis can be done for other buckets and all the bucket tuples merged and reconstructed for complete analysis. This analysis is applied in the medical records. This hybrid slicing technique is rated against Privacy loss and Utility gain factors. Experimental results are analyzed to justify the performance of Slicing+ technique.

Small millets have immense health benefits as they are rich in phytochemicals and nutrients, particularly beneficial to overcome the current life style diseases. On the other hand, in India more than 50 per cent of children are malnourished. Millet based foods help to overcome these two extremes. Millet based products is economically viable and also it highlights the excellent medicinal and nutritional qualities. An attempt was made to develop millet health drink using germinated pearl millet, kodo millet and whole wheat along with pulses. The grains were soaked in water for 3 h and allowed to germinate for 24 h followed by shade dried for 10 h. The dried germinated millets were roasted until husks spilt open and then milled in a burr mill to obtain a fine flour. The flour was then blended with green gram flour, roasted bengal gram flour and skim milk powder. For the standardized health mix, DPPH scavenging activity, product properties such as bulk density, water solubility index and swelling index, proximate composition were studied and also sensory evaluation was conducted for the health drink prepared by using the standardized health mix. DPPH scavenging activity of the health mix was found to be 0.664±0.08 mg/g. Bulk density, water solubility index and swelling were calculated as 0.85 g/cm3, 9 and 1 per cent, respectively. The standardized mix had 17.08 per cent protein, 4.05 per cent fibre, 20.68 mg calcium and 7.57 mg of iron in 100 g. The drink had high consumer acceptability. The nutrient rich health drink was suitable for all groups of people. The mix can be used for preparation of different snacks like sweet ball, steamed food etc.Keywords

Welding structures are nowadays used in many applications such as machineries in industry and in the form of bridges in civil structures. Crack in those structures results in loss of structural integrity which reduces a efficiency of a system in which the structure is used. Hence crack detection of a structure before implementation is important to reduce a defect. Here adaptive changing and morphology is used to detect a crack in structures.
