Cadastral level Soil and Water conservation Priority Zonation using Geospatial technology

Water is the most precious commodity that human being wanted, nowadays water is depleting due to several human interventions. In Kerala state, even though high rainfall is received, still water scarcity is faced during summer and soil erosion is higher. This watershed area is prone to water scarcity during the summer season and stream network become dry during that period. This clearly indicates that human interventions and unscientific agricultural activities may be the result. In this, study GIS and RS technologies are used to find and map the Soil and water conservation priority zones, also several action Plans where proposed. SOI Topo sheet were used to digitize the contours and DEM was created using that with ArcGIS 10.2.2 software. LULC maps were digitized from satellite image and using other parameters and suitable weight values, the weighted overlay was done to find out the Priority Zones. Cadastral Plot boundaries were overlaid for plot-wise priority zones and several conservation methods like gully plugin, check dams, vegetation bund etc. were proposed

THREE PHASE GRID-CONNECTED PHOTOVOLTAIC UNIVERSAL BRIDGE INVERTER APPLYING A BOOST CONVERTER

In this paper, a three phase grid connected universal bridge inverter using a boost converter is suggested for photovoltaic (PV) systems and grid connected systems to improve performance of three phase inverter connected to the grid. The PV grid system has a disadvantage that the output voltage of PV array is low and we need to boost then in order to efficiently convert them into alternating voltage. The boost inductor boosts the output of the PV array to a suitable level so that inverter could convert it into alternating form. The DC/AC inverter is most important part of the PV system

Posterior dislocation hip with anterior column acetabular fracture: a very rare injury

Posterior dislocation is a common injury but it’s occurrence in association with anterior column fracture is very rare. We report a case of this rare injury pattern. The patient was treated with closed reduction of dislocation followed by open reduction internal fixation of anterior column.

Impact of Cypermethrin on Fingerlings of Common Edible Carp (Labeo rohita)

Laboratory evaluations were made to assess the toxicological and biochemical effect of cypermethrin on fingerlings of common edible freshwater culture carp (Labeo rohita). There was a significant negative (P < 0.05) correlation observed between effective doses of cypermethrin and exposure periods; that is, LC50 values decreased from 0.323 μg/L (6 h) to  > 0.278 μg/L (12 h),  > 0.240 μg/L (18 h) and >0.205 μg/L (24 h). Exposure to sublethal doses of cypermethrin for 24 h and 96 h exposure period caused significant (P < 0.05) time- and dose-dependent alterations in total protein, total free amino acids, nucleic acids, glycogen, pyruvate, and lactate level and in the activity of enzyme protease, alanine aminotransferase, aspartate aminotransferase, acid phosphatases, alkaline phosphatases, acetylcholinesterase, and cytochrome oxidase in liver and muscle tissues of fish. Thus, cypermethrin has potent piscicidal activity against fingerlings of fish Labeo rohita and adversely affects their behavioural patterns, shifting aerobic pathway of fish respiration towards anaerobic pathway and also inhibiting energy production by suppressing ATP synthesis

BVR photometry of a newly identified RS CVn binary star HD 61396

BVR photometry of a recently identified RS CVn binary star HD61396, carried out during 2001, is presented. The new photometry reveal significant evolution in the shape and amplitude of light curve when compared with those reported earlier by Padmakar etal (2000). The traditional two-starspot model has been used to obtain the spot parameters from the observed light curve. Changes in the spot area and their location on the stellar surface are discernible from the extracted parameters from the new photometry.Comment: 9 pages including 2 figures and 2 tables.

Projection based algorithms for variational inequalities

This dissertation is about the theory and iterative algorithms for solving variational inequalities. Chapter 1 introduces the problem, various situations in which variational inequalities arise naturally, reformulations of the problem, several characteristics of the problem based on those reformulations, as well as the basic existence and uniqueness results. Following that, chapter 2 describes the general approaches to solving variational inequalities, focusing on projection based methods towards the end, with some convergence results. That chapter also discusses the merits and demerits of those approaches. In chapter 3, we describe a relaxed projection method, and a descent method for solving variational inequalities with some examples. An application of the descent framework to a game theory problem leads to an algorithm for solving box constrained variational inequalities. Relaxed projection methods require a sequence of parameters that approach zero, which leads to slow convergence as the iterates approach a solution. Chapter 4 describes a local convergence result that can be used as a guideline for finding a bound on the parameter as a relaxed projection algorithm reaches a solution

Nutrient Management for Higher Productivity of Swarna Sub1 Under Flash Floods Areas

Two field experiments were conducted at Regional Agricultural Research Station, Tarahara, Nepal during 2012 and 2013 to determine the effect of agronomic management on growth and yield of Swarna Sub1 under flash floods. The first experiment was laid out in a split plot design with three replications; and four different nutrient combinations at nursery as main plots and three age groups of rice seedlings as sub plots. The second experiment was laid out in a randomized complete block design and replicated thrice; with three post flood nutrient doses at six and 12 days after de-submergence (dad). The experiments were complete submerged at 10 days after transplanting for 12 days. The survival percentage, at 21 dad, was significantly higher in plots planted with 35 (90.25%) and 40 (91.58%) days-old seedlings compared to 30 days-old seedlings (81.75%). Plots with 35 days-old seedlings produced 5.15 t ha-1 with advantage of 18.83% over 30 days-old seedlings. Plots with 100-50-50 kg N-P2O5-K2O/ha at nursery recorded the highest grain filling of 79.41% and grain yield of 5.068 t/ha with more benefit. Post flood application of 20-20 N-K20kg/ha at 6 dad resulted in higher plant survival and taller plants, leading to significantly higher grain yield of 5.183 t/ha and straw yield of 5.315 t/ha. Hence, 35-40 days old seedlings raised with 100-50-50 kg N-P2O5-K2O /ha in nursery and the additional application of20-20 kg N-K2O /ha at 6 dad improved plant survival and enhanced yield of Swarna Sub1 under flash flood conditions. The practice has prospects of saving crop loss with getting rice yield above national average yield leading to enhanced food security in the flood prone areas of Nepal

Mediastinal tuberculosis in adult: case report

Mediastinal lymph node enlargement commonly seen in sarcoidosis, lung cancer, lymphoma and tuberculosis in children’s. Tuberculosis in adult mostly involve parenchyma of lung and very rarely involve mediastinal lymph nodes, here we report a 27-year-old male, non-diabetic, non-hypertensive, non-alcoholic and non-smoker who present with low grade fever and dry cough. Search for the cause of morbidity revealed him to be suffering from mediastinal tuberculosis. He was treated for tuberculosis with ATT

Local Linear Convergence of an Outer Approximation Projection Method for Variational Inequalities

This paper considers an outer approximation projection method for variational inequalities, in which the projections are not performed on the original set that appears in the variational inequality, but on a polyhedral convex set defined by the linearized constraints. It shows that the method converges linearly, when the starting point is sufficiently close to the solution and the step lengths are sufficiently small
