 Abstract

Abstract Sacred groves are ecologically important with great heritage of genetic diversity of many local forest based plant species having medicinal, economic, cultural and religious values. The present study was aimed at documenting the wealth of plant diversity of a sacred grove. A survey was conducted to record density, species richness and diversity of woody species (trees and lianas) in the G.Ariyur sacred grove which is dedicated to Aiyanar with an area of 2.5 hectares and which is situated in Tirukkoyilur taluk of Viluppuram district, TamilNadu, South India. A total of 39 plant species representing 37 genera were recorded, belonging to 23 families. Of these, 32 (71%) species were trees and 7 (29%) species were lianas. The dominant families are: Mimosaceae (5 species), Caesalpiniaceae (4 Species) and Rutaceae (4 Species). Apocynaceae, Capparaceae, Fabaceae, Rhamnaceae, Rubiaceae,and Sapindaceae which were represented by two species each from the study site. Density, species richness and diversity of trees were recorded for the detailed study of plant diversity. The vegetation type indicates that this grove is considered to be an inland tropical dry evergreen forest.

Abstract: Today the Growth of Technology and utilization of CNC machine are Rapid increased. Numerical control is such a useful thing that can control a machine with numeric values and codes. That is what we call CNC machine, used in machining or any other automation. The commercial CNCs are bulky and so much expansive and not possible to afford by normal people in home. So the machine with computer ability and in less size mini CNCs came in. CNCs are much complex in its function. It works with the simultaneous interpretation of software and hardware. The three axis motion is controlled by Arduino Uno board with Atmega 328p microcontroller. The Arduino works here as an open source burner which burns the microcontroller with given hex codes. The CNC shield along with stepper motor drivers basically receives the signals from the Arduino board and delivers the power to the stepper motors. In this machine only G codes are used to command or instructions. G codes are language, by using this person Told computer control machine tool. The microcontroller converts G-code into a set of machine language instruction to be sent to the motor driver of the CNC plotter.

 Abstract

Speed control is an essential requirement for getting different values according to the application.. Speed control can be done manually by operator or by automatic control device. Speed control can be done easily in DC motor. In this model we are controlling the speed of DC motor using PWM (PULSE WIDTH MODULATION) TECHNIQUE. The speed of DC Motor is varied according to the temperature with the help temperature sensor and Arduino.

 Abstract

Geopolymer is a green cementitious material and has excellent mechanical properties, low energy in its production and emits less carbon dioxide. In this paper, the effect of silica fume on durability properties of fly ash based geopolymer concrete have been investigated by immersing the cubes in 2% sulphuric acid and 5% sodium chloride solutions. The resistance of specimens to chemical attackwas evaluated visually, measuring change in the weights and percent losses incompressive strength at different intervals of time. A control mix was also cast as M40 with ordinary Portland cement concrete for comparison. Percent losses in compressive strengths in the case of control (M40) and GPC3 in 2% H2SO4 at 90 d were found 36 and 8%. Percent losses in compressive strengths in the case of control (M40) and GPC3 in 5% NaCl at 90 d were 18% and about 0%.Thus the resistance of geopolymer concrete incorporating silica fume in sulphuric acid and chloride solution was significantly higher than that of the control.The cube specimens are taken of size 100 mm x 100 mm x 100 mm. Ambient curing of concrete at room temperature was adopted. In total 36 cubes were cast for different mix Id and the cube specimens are tested for their compressive strength at age of 1 day, 7 days and 28 days respectively. The result shows that geopolymer concrete cubes gains strength within 24 hours without water curing at ambient temperature. Also the strength of geopolymer concrete was increased with increase in percentage of GGBS in a mix. Thus the geopolymer concrete is considered to be an environmentally pollution free construction materials.

Abstract: Indian companies practice Corporate Social Responsibility for more than the decades. CSR become a popular concept in India. Companies should spend on CSR as a community obligation and not as a compulsions and fear. Companies should not restrict their spending on traditional social welfare projects. In India CSR is in a very much budding stage. This research paper focuses on the CSR spending of two hundred and fifty companies. Study also highlights theme based spending across all the sectors and finally focused on top ten CSR spending companies and concluded paper with findings and some valuable suggestions.

In a federated environment like Cloud Computing security remains major concern for cloud users as their sensitive data is handled by a third party. Identity management plays major role in Cloud security. This paper aims to provide means of understanding new dimensions of identity management in cloud security and necessity of building dynamic trust relationships for efficient federated identity management.

 Abstract

Internet penetration and technological innovation helped India to reach more than 300 million smartphone users. There are innumerable mobile applications available for one or the other services. Health and wellness industry is not an exception. This paper primarily focused on how people are adopting and is there any difference among males and females in the adoption. Data is collected using non-list based online probability sampling using social media, email, WhatsApp etc. Five important parameters PU (potential usefulness), PEOU (perceived ease of use), favourable attitude, usage intention and trust considered to understand the difference between male and female and among different age groups. Results clearly show that females are adopting technology faster than their male counterparts. Users, who are Generation X, adopt mobile health app technology especially female, and to understand the significant difference between different group z-test is used. There are various research papers available regarding technology adoption, comparative study on mobile app adoption but related to health app very few are there. No study, focus on health app study particularly from age and gender wise. This study focuses and addresses this research gap.

 Abstract

Surfactants are chemical products widely used in our daily life in toothpaste and other personal hygiene and cosmetic products, and in several industries. Biosurfactants are surfactants of biological origin that can be produced by microorganisms and have many advantages, such as low toxicity and high biodegradability, compared to synthetic counterparts. Unfortunately, high production costs limit the use of biosurfactants. Low-cost production is the most important factor for biosurfactants to be able to compete in the global market place. Effort was made to study the biosurfactants from bacterial species isolated from petroleum contaminated sites.
