Background: Scalar multiplication is having the scope for gaining the computational efficiency for Elliptic Curve Cryptography (ECC). The security strength and effectiveness have been better reported on shorter key lengths. Methods: The Edwards curves are one of the form used in cryptography is showing one of advanced study for generating the more randomness and unpredictability behaviors. The numbers of researchers have shown the significant improvement to solve the same problem on two, four and eight processors and that are contributing the immense contribution in the field of security. Findings: The manuscript solves the Edwards Curves and twisted Edwards Curves problems on four and eight processors based on reduced computation cost from to on four processors and to on 8-processors, respectively. Our generalized computation cost on 8-processors for -bit scalar multiplication is reporting better than the cost for Montgomery Ladder method and for extended twisted Edwards curves on radix-8. Applications: The operation is performing on input scalar which multiplies with point-coordinates on curve, which has accumulated on reduced clock cycles with resistance to the simple side channel attack.Keywords

Improvements in the field of diagnostic studies as well as better understanding of various benign conditions affecting gallbladder may explain the rise in the incidence of it, including gallstones rather than the change in the living standards of Indian population. In the present scenario, this study tries to find out the instance of other benign conditions of gallbladder amongst the patients presenting themselves for laparoscopic cholecystectomy. This study will also look through a detailed review of literature whether in these benign conditions of gallbladder, laparoscopic procedure should be the procedure of choice.
All the patients admitted with symptomatic gallbladder diseases are treated with cholecystectomy. After the advent of laparoscopic surgery, laparoscopic cholecystectomy has become the gold standard procedure for gallbladder removal for benign indications and is the preferred mode of surgery now. Many comparative studies between laparoscopic cholecystectomy and open cholecystectomy in developed countries have been discontinued because patients are refusing the open procedure for the superior procedure, i.e., laparoscopic cholecystectomy primarily due to its completeness and safety, better cosmesis and almost no post-operative pain and discomfort.
This study tried to find out the spectrum of the benign diseases/conditions of gallbladder, which necessitate its removal and also keep in mind about the documented premalignant conditions of the gallbladder, which are benign; and evaluate the prognosis of the patients with such conditions over a period of time to understand whether laparoscopic cholecystectomy should be considered to be the proper form of therapy in all these patients.

In hydrodynamic lubrication of journal bearing pressure of the fluid film is generated as a result of the viscous drag of the fluid into the wedge shaped gap between the journal and bearing due to relative motion of the journal with respect to the bearing. The pressure development of fluid is important in this type of lubrication to ensure performance of journal bearing. On the other hand, every surface has some degree of roughness that affects relative motion of the journal bearing system. This paper, thus, aims to present a detailed study of hydrodynamic pressure built up of a journal bearing including the roughness of the surfaces. The modified Reynolds equation is derived on the basis of theory of micropolar lubrication incorporating suitable roughness model. The resulting equation is solved numerically at steady state operating condition using cavitation boundary condition to observe distribution of pressure. The effects of variations in operating variables in terms of characteristic of lubricant and parameters defining roughness model are computed. The analytical results are compared with the available published results to validate the theory and computer code. The numerical result shows that for same geometrical condition maximum pressure developed in micropolar fluid always remain higher than that in Newtonian fluid. The steady state pressure is found to be decreased as the values of the roughness parameters are increased.Keywords

During high growth years, 2004-2012 India achieved an average of Eight per cent growth rate. But on the job front, it didn’t see much growth and real wages were almost stagnant. We have now the world third largest economy based on real GDP. But based on per capita income we are at 138 th position as we have failed to create enough jobs for our labour force. This book addresses both the problem as well as its solutions. It explains India’s growth story since independence and some lapses in policy such as regulatory barriers, inspector Raj, closed economy, low productivity in agriculture, low skill levels, etc.

The baobab tree, Adansonia digitata L. (Malvaceae), is a native of Africa. Baobab is a multipurpose tree that provides protection food, clothes and medicine, as well as raw materials for a verity of products. Baobab’s fruits pulp, seeds, leaves, flowers, roots and bark are edible and it is qualities have been researched by scientists. The fruit pulp has the large amount of vitamin C, calcium, Phosphate, crabs, fibers, potassium, proteins and lipids can be used an appetizer or drink. Seeds are high in lysin, thiamine, calcium and iron and include significant amount of phosphorous, magnesium, zinc, sodium, iron, and manganese. Antimicrobial, antimalarial, diarrhea, anemia, asthma, antiviral, antioxidant, and anti-inflammatory characteristics are only a few of the biological qualities of baobab. Flavonoids, phytosterols, amino acids, fatty acid, vitamins and minerals were discovered by phytochemical analysis.Keywords

Adansonia digitata is a unique tree with their tender root, twigs, seeds, leaves, tubers, fruits and flowers which are edible. The Adansonia are also used for treat of various types of disease disorder due to their nutritional and chemical contents. This plant is mostly found in South Africa and Asian countries. In this paper, we represent the nutritional benefits of Adansonia digitata tree parts vise its fruits pulp, seeds, and leaves etc. The medicinal properties of the tree parts as well as the medicinal compound contained are discussed on addition. In this paper, the nutrition benefits of seeds oil are concluded use as premium oil.Keywords

Advances in computer methods over the last two decades have accelerated research in engineering sectors because of high computing power. Micro-machining is a manufacturing domain that is widely utilized for producing miniature components where predictability is a concern. The current work emphasized developing and executing a user-defined constitutive flow and friction models to simulate the physical phenomenon of chip morphology, residual stresses, and cutting forces during orthogonal machining at the micro-scale. The proposed model integrates strain gradient and dynamic recrystallization effect using a user hardening subroutine written in Fortran for machining of Ti-6Al-4V in micron scale. Furthermore, a user defined friction subroutine was implemented at the tool-chip interaction. A comparison is made between the modelling results and experiments in terms of specific cutting energy (SCE) and residual stresses.Keywords
