TL;DR: An artificial neural network technique with gradient descent and particle swarm optimization is used to obtain the numerical solution of the Troesch’s problem and the results are more approximate and solution is provided on continuous finite time interval unlike the other numerical techniques.
Abstract: In this article, a simple and efficient approach for the approximate solution of a nonlinear differential equation known as Troesch's problem is proposed. In this article, a mathematical model of the Troesch's problem is described which arises in confinement of plasma column by radiation pressure. An artificial neural network (ANN) technique with gradient descent and particle swarm optimization is used to obtain the numerical solution of the Troesch's problem. This method overcomes the difficulty arising in the solution of Troesch's problem in the literature for eigenvalues of higher magnitude. The results obtained by the ANN method have been compared with the analytical solutions as well as with some other existing numerical techniques. It is observed that our results are more approximate and solution is provided on continuous finite time interval unlike the other numerical techniques. The main advantage of the proposed approach is that once the network is trained, it allows evaluating the solution at any required number of points for higher magnitude of eigenvalues with less computing time and memory.

TL;DR: A comparative study of Particle Swarm Optimization (PSO) and Gravitational Search Algorithm for the coordination of overcurrent relay for a system containing DG to avoid mal operation of relays and unwanted outages when DG is penetrated.
Abstract: Modern distribution systems consist of various distributed generators (DG) to make reliable power systems. In these DG integrated distribution systems, coordination of overcurrent relays is a big challenge for protection engineers. With the addition of DG, distribution system experiences change in the short-circuit level of the system and thus earlier relay settings causes mal operation of relays. Nowadays, various programming optimization techniques are frequently used to find optimal relay settings of overcurrent relays. This paper presents a comparative study of particle swarm optimization and Gravitational Search Algorithm for the coordination of overcurrent relay for a system containing DG. A proper combination of primary and backup relay is selected to avoid mal operation of relays and unwanted outages when DG is penetrated. Practical cases with different DG penetration level and fault types are also thoroughly discussed. A 4-bus radial system is simulated in PSCAD/Simulink platform and programming is done using MATLAB software.

TL;DR: The present chapter attempts to provide the contemporary knowledge regarding the metal-influenced antioxidant status in plants and also provides the precise pathway that should follow for the future research in the area of antioxidant potentials.
Abstract: Heavy metals (HMs) are consequential environmental contaminant, and their prodigious bioaccumulation in the surroundings has become an enigma for all living organisms including plants. Heavy metal has the potential to react with various indispensable cellular components like DNA, protein, and enzymes and in turn induce several stress responses in plants like oxidative stress which is the root cause for the progression of cell death in the plant. Stress responses inflicted by oxidative stress include severe morphological, metabolic, and physiological amendments in plants like DNA strand breakage, defragmentation of proteins, and damage of photosynthetic pigment, which may stimulate cell death. In reaction, plants have a range of mechanisms to minimize the heavy metal toxicity. Plants are endowed with antioxidant defense mechanism, which can be divided into two groups such as enzymatic antioxidants and nonenzymatic antioxidants, for instance, SOD, CAT, APX, GPX, GR and AsA, GSH, carotenoids, alkaloids, tocopherols, proline, and phenolic compounds, respectively, that together act as the scavengers for free radicals to mitigate the damaging impacts of heavy metal agglomeration in the cells. These antioxidant potentials could be assessed by different in vivo and in vitro methods such as hydrogen atom transfer and electron transfer through which we can evaluate the ROS detrimental action of antioxidant enzymes. Therefore, the present chapter attempts to provide the contemporary knowledge regarding the metal-influenced antioxidant status in plants and also provides the precise pathway that should follow for the future research in the area of antioxidant potentials.

TL;DR: The new closed form solutions of the ( 2 + 1 )-dimensional Zabolotskaya–Khokhlov equation are constructed by using the similarity transformations method via Lie group theory, reduced into a new partial differential equation with smaller number of independent variables.
Abstract: The new closed form solutions of the ( 2 + 1 )-dimensional Zabolotskaya–Khokhlov equation are constructed by using the similarity transformations method via Lie group theory. The Zabolotskaya–Khokhlov equation has been reduced into a new partial differential equation with smaller number of independent variables. Further using the similarity transformations method the new partial differential equation is reduced into an ordinary differential equation. The ordinary differential equation provides semi analytical solutions. Elastic behaviour of multisolitons and dromion annihilation of solutions are analyzed physically through their evolutional profiles.

TL;DR: The present study suggests that the enzyme obtained from strain B. subtilis can be used as feed supplement in animal diet also for reduction of phosphorus pollution problem in areas of livestock production.
Abstract: Background: Cereals, legumes, and oilseed crops are very important crops as nutrition for human and animals. Phytate (myo inositol hexa kis phosphate) is the main storage form of phosphorus in these crops. These crops are major source of nutrients for humans and animals including fish, poultry and pig. Phytic acid is the nutritional constituent of animal diet but it is not digested by monogastric animals because they do not contain phytase enzyme in their intestines to break the phytic acid and due to this, phytic acid acts as an antinutritional chelating agent for various metal ions like Ca, Mg, Fe, Zn, and etc., so that reduced the nutritive quality of food. Objectives: Phytase is an important enzyme in the food/feed industry; therefore, isolation of phytase producing bacteria and optimization of phytase production on different parameters were performed in this study. Materials and Methods: The present study was conducted in Biotechnology laboratory, Motilal Nehru National Institute of Technology, Allahabad, Uttar Pradesh, India. To isolate phytase producing bacteria from different soil samples like cattle shed, pulse crop field, poultry farms, and etc. 0.1 gr of the soil samples were streaked on phytase screening medium. The qualitative screening of the isolates was performed on phytase screening medium plate with 1.5% agar, and phytase activity was determined by using shaking flask method. The best phytase producer was optimized using different parameters of phytase production. Results: We isolated 32 phytase producing bacteria on phytase screening media. Upon screening of these strains, one of the best strain (DR6) which showed a 39 mm clear zone on phytase specific medium (PSM) was identified as Bacillus subtilis. So this strain was selected for further enzymatic assay and optimization. This strain showed 378U/mL enzymatic activity upon enzymatic assay, the result of optimization of this best strain was performed at different parameters, and this strain showed best results at pH 5.5, Temp 50 °Cwith Glucose + Sucrose as Carbon source and Yeast extract as Nitrogen source. Conclusions: The present study suggests that the enzyme obtained from strain B. subtilis can be used as feed supplement in animal diet also for reduction of phosphorus pollution problem in areas of livestock production.
