Abstract

An antioxidant is a molecule capable of slowing or preventing the oxidation of other molecules or a substance that combines with or otherwise neutralizes a free radical, thus, preventing oxidative damage to cells and tissues. According to FDA, antioxidants are defined as substances used to preserve food by retarding rancidity and discoloration due to oxidation. Oxidation is a chemical reaction that transfer electron from a substance to an oxidizing agents. Oxidation reaction can produce free radicals, which start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radicals intermediates and inhibit other oxidation by being oxidised themselves. As a result, antioxidants are often reducing agents such as thiols, ascorbic acid or polyphones. Although, oxidation reactions are crucial for life, they can also be damaging, hence, plants and animals maintain complex system of multiple types of antioxidants, such as glutathione, vitamin C and vitamin E, as well as enzymes such as catalyses, superoxide dismutase and various peroxidases. Low level of antioxidants or, inhibition of the antioxidants enzymes, causes oxidative stress and may damage or kill cells.An oxidative stress might be an important part of many diseases; the use of antioxidants in pharmacology is intensively studied, particularly as treatment for stroke and neurodegenerative diseases. Antioxidants are also widely used as ingredient in dietary supplements in the hope of maintaining health and preventing diseases such as cancer and coronary heart disease. In addition to these uses of natural antioxidants in medicines, these compounds have many industrial uses such as preservation of food, cosmetics, preventing the degradation of rubber and gasoline

Abstract

Load balancing by virtual machine migration is one of the most significant issues in cloud computing research. A basic approach is to use intelligent algorithms such as Ant Colony Optimization (ACO). However, the main issues with traditional ACO is that it dependents on the initial conditions, which affects the convergence speed and final optimal solution. To solve this problem, we propose Max-min Algorithm. Another problem, ACO could arrive at local optimal point, and the convergence speed is typically low. Along this line, we introduce the idea of max-min optimal feature selection to avoid local optimal and accelerate the convergence. Lastly, our experiments show that our improved ACO (Max-min ACO Algorithm) achieves good performance in load balancing. The experimental results show that SLA violations and number of migrations are reduced. The new scheduling strategy was simulated using the Cloud-Sim toolkit package.

Abstract

Crop Simulation Models helps to estimate crop yield on the basis of some parameters like temperature, soil, weather and crop etc. DSSAT-CSM (Decision Support System for Agro-technology Transfer - Cropping System Model) is an extension of DSSAT crop model. DSSAT-CSM contains a modular structure which has various modules that work along various parameters and give the desired output. CropSyst is a user friendly, multi-year, multi crop, daily time step cropping system simulation models which is used to study the effect of cropping system management on productivity and the environment. It takes the factors such as soil-water budget, crop canopy and ischolar_main growth, soil-plant nitrogen budget, residue production and decomposition and management options like crop rotations, irrigation, nitrogen fertilization and tillage operations into consideration. DSSAT and CropSyst both are used to analyse growth production but based on different input parameters.
