Change Detection of Vegetation Cover by NDVI Technique on Radhangari Wildlife Sanctuary of Kolhapur District in Maharashtra, India
The degradation of green cover has been going on since the beginning of human culture in space. The loss of natural forests as a result of progressive activities has become a major environmental concern. The loss of green vegetation is a fact of hydroelectric power generation by impeding the natural flow of a river. It has an influence on both the upper and lower catchment areas' vegetation. Various techniques of Vegetation Index (VI) based on Remote Sensing (RS) and Geographical Information System (GIS) methods are used to analyses this damage. One of the most widely used techniques for assessing vegetation cover is the Normalized Difference Vegetation Index (NDVI. For this study three decade has taken for calculating the NDVI of Radhanagari wildlife Sanctuary. After calculating the NDVI it shows the year 1998 shows 0.71 highest NDVI value and -0.48 was lowest, in the year 2008 highest NDVI was 0.38 and the lowest was -0.46 and for the year 2018 it was 0.49 highest and -0.12 NDVI values. This decreased NDVI represent forest area has degraded rapidly
AN ANALYTICAL STUDY ON FOREST RESOURCE AND TRIBAL WOMEN LIVELIHOOD IN INDIA
The study is going to an attempt to tribal women livelihood on forest in India. Forest is an integral part of tribal life. They lead life on forest resource. It is a right of tribal. Itâs denied by colonial period after the independence removes some restriction on forest by government. The tribal women have a heritage of close association with forests. As per the 2011 census, the tribal population of India, is 10.43 crore, constituting 8.6% of the total population. India is largely high portion of tribes in comparatively other countries .To investigation of historically forest is home for tribes their dependency is on this. The present study is an exploring to concern of forest to tribal women livelihood for this followed secondary source. There are most of areas covered by forest, there many tribes are depends on forest resource to lead life. The forest policy and act gives legal right to tribal to consume forest resource as well as genuinely role in empower the tribal women livelihood and human rights of tribes and many laws enacted in context of forest to improvement in forest regulation and protection instructions about consumption forest. The present study has been undertaken to investigate the tribal women livelihood contributions of forest resources and livelihood of tribal women by forest resources
Exercise-induced rhabdomyolysis with acute kidney injury: A case report with review of literature
Exercise-induced rhabdomyolysis is a medical condition that results from muscle injury. Renal failure is the most serious complication of rhabdomyolysis, but is rare. We report a case of acute kidney injury following heavy exercise in a healthy, young adult
Impact of wild animal invasion on human society in Ajara Tehsil: A geographical analysis
Man and animals are continually at odds over habitat and food requirements due to the expanding human population and the loss of natural environments. This topic has been acknowledged as a severe challenge by several countries. It is significant to many people. There are numerous human communities. Because they are located in thickly forested areas, forest communities are the most sensitive to this problem. The points where human needs and those of wild creatures collide In the Ajara tehsil, located in the southern part of the Kolhapur district of Maharashtra. However, no comprehensive research on man-wildlife conflict in these villages has yet been conducted. As a result, the current study aimed to identify the numerous wild creatures involved in violence in the region's forest settlements. The study discovered that three conflict animals were most typically related to the problem in these villages

Li, Na, K, Mg, Zn, Al, and Ca Anode Interface Chemistries Developed by SolidâState Electrolytes
Abstract Solidâstate batteries (SSBs) have received significant attention due to their high energy density, reversible cycle life, and safe operations relative to commercial Liâion batteries using flammable liquid electrolytes. This review presents the fundamentals, structures, thermodynamics, chemistries, and electrochemical kinetics of desirable solid electrolyte interphase (SEI) required to meet the practical requirements of reversible anodes. Theoretical and experimental insights for metal nucleation, deposition, and stripping for the reversible cycling of metal anodes are provided. Ion transport mechanisms and stateâofâtheâart solidâstate electrolytes (SEs) are discussed for realizing highâperformance cells. The interface challenges and strategies are also concerned with the integration of SEs, anodes, and cathodes for largeâscale SSBs in terms of physical/chemical contacts, spaceâcharge layer, interdiffusion, latticeâmismatch, dendritic growth, chemical reactivity of SEI, current collectors, and thermal instability. The recent innovations for anode interface chemistries developed by SEs are highlighted with monovalent (lithium (Li+), sodium (Na+), potassium (K+)) and multivalent (magnesium (Mg2+), zinc (Zn2+), aluminum (Al3+), calcium (Ca2+)) cation carriers (i.e., lithiumâmetal, lithiumâsulfur, sodiumâmetal, potassiumâion, magnesiumâion, zincâmetal, aluminumâion, and calciumâion batteries) compared to those of liquid counterparts
Hierarchically Designed 3D Holey C2N Aerogels as Bifunctional Oxygen Electrodes for Flexible and Rechargeable Zn-Air Batteries
PRIORITY BASED AUTOMATIC MULTI SOURCE SWITCHING USING PLC
The main purpose of this project is to provide continuous power supply to the load by switching the supply. In case if anyone of the source is absent from the following four sources namely solar, inverter, mains and generator. Automatically other three provides backup & shares the load .The graph of need of electric supply is growing day by day and the frequent power disconnection of electricity are causing many issues in different areas like banks, colleges schools, hospitals, houses and industries. Thus there is requirement of Energy source for an alternate arrangement of power supply. In this project arrangement has been designed by using Allen Bradely PLC and relays. When a source, say mains fails the power supply to the load then automatically it shifts to next priority source generator and so on. LEDs are used to indication purpose for running source which is used to provide the supply
Scalable 3âD Carbon Nitride Sponge as an Efficient Metal-Free Bifunctional Oxygen Electrocatalyst for Rechargeable ZnâAir Batteries
Rational
design of efficient and durable bifunctional oxygen reduction
reaction (ORR) and oxygen evolution reaction (OER) electrocatalysts
is critical for rechargeable metalâair batteries. Here, we
developed a facile strategy for fabricating three-dimensional phosphorus
and sulfur codoped carbon nitride sponges sandwiched with carbon nanocrystals
(P,S-CNS). These materials exhibited high surface area and superior
ORR and OER bifunctional catalytic activities than those of Pt/C and
RuO<sub>2</sub>, respectively, concerning its limiting current density
and onset potential. Further, we tested the suitability and durability
of P,S-CNS as the oxygen cathode for primary and rechargeable Znâair
batteries. The resulting primary Znâair battery exhibited a
high open-circuit voltage of 1.51 V, a high discharge peak power density
of 198 mW cm<sup>â2</sup>, a specific capacity of 830 mA h
g<sup>â1</sup>, and better durability for 210 h after mechanical
recharging. An extraordinary small chargeâdischarge voltage
polarization (âŒ0.80 V at 25 mA cm<sup>â2</sup>), superior
reversibility, and stability exceeding prolonged chargeâdischarge
cycles have been attained in rechargeable Znâair batteries
with a three-electrode system. The origin of the electrocatalytic
activity of P,S-CNS was elucidated by density functional theory analysis
for both oxygen reactions. This work stimulates an innovative prospect
for the enrichment of rechargeable Znâair battery viable for
commercial applications such as armamentaria, smart electronics, and
electric vehicles
