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

Protic Reaction Media for Nucleophilic Substitution Reactions

This chapter deals with the unusual substitution reactions in non-aprotic solvent. Selective protic solvents that are widely being accepted for nucleophilic substitution reactions not only enhance the reaction rate but also give desire for selectivity of substituted product. Protic solvents such as tert-alcohol, primary alcohol, ionic liquids with tert-alcohol and primary alcohol functionality, and bis-cationic ionic liquid with protic functionality were shown best result in substitution reactions. Aliphatic nucleophilic substitution significantly developed in protic reaction medium due to the hydrogen bonding interaction with leaving groups and nucleophile. The development of substitution reactions from past two decades are summarised in this book chapter

Data Transfer via Human Body

In this paper we are providing a overview of recent researches on body as a communication media i.e. creating a ‘HAN’ network. We use different communication media in our daily life such as LAN, WAN, VAN, MAN, etc... So according to research the new concept is came into account as “RED TACTON” which makes the human body as a communication media. It mainly create HAN network. It proved a better communication for near field where transmitter and receiver are in close proximity. RED TACTON mainly makes the use of electric field generated by the person’s body as medium for transmitting data. For making use of human body as transmission media we have to first study the concept of intrabody communication In which the human body characteristics (distance, resistance, the effect of ground plane to body channel Trans receiver and proper frequency range for intra body communication etc.) as signal transmission media are explained thoroughl

Keyless Security: The Smart Solution for Home with a Smart Door Lock

This research paper introduces a novel approach to improve security and access control in smart door lock systems. The proposed system incorporates multi-factor authentication, combining a numerical keypad, mobile app, and RFID sensor. Each authentication method is associated with a specific lock, offering differentiated access control. Notably, the system requires the simultaneous use of the mobile app and RFID sensor to unlock a designated lock, adding an extra layer of security. To assess the system's effectiveness, a comprehensive study was conducted, considering security, usability, and user satisfaction. The study involved simulated attacks, user surveys, and usability tests, with data analysis providing insights into the system's resilience and user acceptance. This research contributes to the field of smart door lock systems by offering an innovative approach to enhance security through multi-factor authentication. The findings provide valuable insights for designing advanced access control mechanisms, empowering users with increased confidence in their security measures while maintaining a user-friendly experience

Therapeutic Outcomes of Isatin and Its Derivatives against Multiple Diseases: Recent Developments in Drug Discovery

Isatin (1H indole 2, 3-dione) is a heterocyclic, endogenous lead molecule recognized in humans and different plants. The isatin nucleus and its derivatives are owed the attention of researchers due to their diverse pharmacological activities such as anticancer, anti-TB, antifungal, antimicrobial, antioxidant, anti-inflammatory, anticonvulsant, anti-HIV, and so on. Many research chemists take advantage of the gentle structure of isatins, such as NH at position 1 and carbonyl functions at positions 2 and 3, for designing biologically active analogues via different approaches. Literature surveys based on reported preclinical, clinical, and patented details confirm the multitarget profile of isatin analogues and thus their importance in the field of medicinal chemistry as a potent chemotherapeutic agent. This review represents the recent development of isatin analogues possessing potential pharmacological action in the years 2016–2020. The structure–activity relationship is also discussed to provide a pharmacophoric pattern that may contribute in the future to the design and synthesis of potent and less toxic therapeutics

Investigation of phase equations for anaerobic digestion process of anaerobic bioreactor landfill

The anaerobic digestion process consists of four phases hydrolysis, acidogenesis, acetogenesis and methanogenesis. In the present work anaerobic digestion process of waste from anaerobic bioreactor landfill is considered and leachate is analyzed chemically for 268 days and out of all 17 parameters, seven major chemical parameters are studied for two reactors R4 and R5 for different reactor conditions and their phase distribution is done by two methods standard and transitory method. These phase distribution also gives phase wise equation, for optimization of entire process each phase equation is essential. The accuracy of curve equations is defined by R2 value. These equations help in formation of mathematical model using MATLAB. This model is useful for defining phase values of parameters. Further quality and quantity of chemical parameters are also defined by these phase values
