Salinity is one of the abiotic stress factors that negatively influence agricultural productivity and thereby affects world economy. It is a complex multigenic trait governed concurrently by many metabolic pathways. Detoxification of excess Reactive Oxygen Species (ROS), produced due to salt stress, by antioxidants is one of the strategies followed in living organisms to combat such stress. Manganese-Super Oxide Dismutase (Mn-SOD) is one such antioxidant metallo-enzymes, which plays a major role to scavenge ROS in diverse species. However, it is found that only few important residues of Mn-SOD enzyme neutralize excess ROS. Hence, the aim of this study is to identify the key residues of Mn-SOD that are actively involved in salt stress tolerance mechanism and that too conserved across species, through in silico proteomic analysis. In this study, protein sequences of Mn-SOD enzyme from diverse organisms associated with salt stress tolerance were collected from public domain and the conservancy of residues was studied both at sequence and structural level. The residues thus found to be conserved were reported as the key residues playing a significant role in salt stress tolerance mechanism in terms of contribution to the cofactor and substrate specificity, active site gateway formation and protein stability.

A solar still is viable option when demand of potable water does not exceed more than 3 liters. Enhancement in distillate output from the solar still is a main goal of many researchers in all over the world. In this research work, effect of using the copper and aluminium plates on distillate output is investigated experimentally as well as theoretically at different water depths under same climate conditions. In solar stills, first solar still augmented with copper plate, second with aluminium and third without any plate called passive solar still. An energy balance equations applied to solar still for calculation of theoretical distillate output of solar still with different plates. Three experimental still of 1 m2 each are constructed by locally available materials. In this research work, it is found that the results of experimental and theoretical results are in good agreement. It is also found that, using copper plate in solar still increases distillate output of 20 % (at water depth of 3 cm) and 32 % (at water depth of 6 cm) compared with passive solar still and using aluminium plate in solar still increases distillate output of 10% (at water depth of 3 cm) and 20 % (at water depth of 6 cm)

The theme of value creation, being the source of research, has increased interest in the field of management science, and hence became the new creed of managers. We have proposed the ethical behavior of managers influence the policy of value creation. In particular, we test the four cardinal virtues of the manager, who are the justice, prudence, strength and moderation, influence the development and growth of the company.\nThis paper attempts to make an inventory of ethical problems in a country sends development and clarify their role in the development of firms. We used a sample of Tunisian companies for a period to 2003-2011

In this dynamic scenario the communication no longer happens in predetermined manner. The network as a platform for communication comes with high infrastructure may likely to waste the resources. Thus, the ad hoc scenario networks came into existence. This network functionality has been enhanced through clustering mechanism. These clusters need to be perfect to sustain the efficient functionality of the network. Thus, this paper proposes F-PAC as a fuzzy logic based cluster validation technique to authenticate the cluster head identified by the W-PAC mechanism. This study has been shown using OMNET++ as simulator.

The life cycle assessment of Autoliv´s night vision camera shows higher global warming from use phase. This is because of energy use for the functioning of camera. The other major contribution of global warming is from transportation phase. This includes transportation of camera for installation and materials transportation for manufacturing of components. In this paper the transportation phase is discussed. If manufacturing of some components are transferred from America to Europe and camera is assembled in Europe instead of United States, the global warming percentage from transportation phase has been reduced from 17% to 7%.The material in camera that can be replaced/reduced for the environmental reasons is also discussed . Zinc and ceramic are found to be toxic from an environmental point of view. Finally, the environmental results by using electronic safety components and mechanical safety components in a vehicle are analyzed in this paper. The Mechanical safety components have more impacts than electronic components. But it depends upon choice of impact categories e.g. choosing global warming, eutrophication and eco toxicity, mechanical components have more impacts while with human toxicity and acidification, it is vice versa.

Flavonoids constitute a large class of polyphenols found in plants. Among flavonoids, Flavonols are the most abundant and widely distributed in nature. Flavonols are widely distributed in plants and are present in considerable amounts in fruits and vegetables. Flavonols show a wide range of biological activities. In the present study the binding affinity of flavonols against the drug target Malonyl Coenzyme A was calculated by performing the docking experiment by using FlexX. The analysis showed that flavonols has high potentiality to inhibit the drug target Malonyl Coenzyme A. The docking studies also showed greater affinity of all the compounds towards the active site of Malonyl Coenzyme A with a docking score of -29.2358 with Morin, -29.0486 with Kaempferol, -28.3885 with Fisetin, -27.5950 with Quercetin, -27.5303 with Isorhamnetin, -25.7692 with Myricetin, -24.9174 with 3-OH-flavone and -23.5732 with Tamarixetin. The study reveals the probable mode of cardioprotective activity of these flavonols by inhibiting Malonyl Coenzyme A.

Objectives: To evaluate the comparative antimalarial effects of three plants, Picrorhiza kurrooa Royle ex Benth., Cissampelos pareira L. and Tinospora cordifolia (Willd.) Hook.f. & Thoms from different parts of Himachal Pradesh (India).\nMethods: Screening of plant extracts for their antimalarial activity was carried out following Peter\'s 4-day test. This test was followed to evaluate the blood schizontocidal action against P. berghei. Plant extracts were prepared from roots of Cissampelos pareira L., Picrorhiza kurrooa Royle ex Benth and stem of Tinospora cordifolia (Willd.)Hook.f. & Thoms. The extract was given in concentration of 500 mg/ kg body weight per dose per day to the experimental animals. These extracts were given to the mice in aqueous medium daily from day 0 to day 3 by oral route. A control group of mice received chloroquine at 4 mg/ kg standard antimalarial. Untreated control group was given only plain water. Plasmodium berghei (NK-65), a rodent malaria parasite, was maintained in white Swiss mice, Mus musculus (BALB/c).\nResults: These three plants have shown antimalarial effects. In the group of mice which were treated with extract Picrorhiza kurrooa showed mean parasitaemia of 4.36 ± 2.25 and percent of infection ranged between 1.9% to 6.9%. Mice which were treated with extract of Cissampelos pareira L. mean parasitaemia was 11.64 ± 4.20 and percent infection ranged between 6.28% to 16.06% on day 4 while those treated with Tinospora cordifolia showed mean parasitaemia of 13.90 ± 2.25 with parasitaemia ranging between 10.42% to 16.44%.\nConclusions: The present study clearly establishes antimalarial impacts of these plants and revealed that P. kurrooa have maximum antimalarial properties followed by Cissampelas praeiraare and Tinospora cordifolia.

A matrix converter is an ac-ac power converter topology that has received extensive research attention as \nan alternative to traditional ac-dc-ac converter. A matrix converter is able to convert energy from an ac source to ac \nload without the need of bulky and limited-lifetime energy-storage elements. This paper discusses the novel \ntechniques for controlling matrix converters using intelligent techniques, thereby controlling an electrical drive. PI \ncontrollers are employed for speed control (Direct Torque Control) of 3Φ Induction Motor drives. Various \nintelligent techniques adopted in this paper for control are Fuzzy Logic and Adaptive Neuro Fuzzy Inference System \n(ANFIS). Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) are the various optimization \ntechniques proposed to optimize the gains of PI controllers of the process. The performance of the system is \ncompared in terms of time domain specifications using intelligent and various optimization techniques and \nsimulation results are presented. The investigation in this paper reveals that ACO based optimization is better in all \naspects than PSO based techniques.
