Abstract: Electrical Discharge Machining (EDM) is a non-traditional process that uses electrical thermal energy to machine metals. It is extremely useful in machining hard materials. With the advantages, EDM has to offer and its presence as a common and useable technique, along with the other machining processes available to the industrial world, there is an added strain on the environment. The scope of this paper includes the optimization and analysis of dependent variables in EDM and the resulting outputs by experimentation on SS-316.

The present study aims towards examining physiological, biochemical, anatomical and molecular traits in the high-yielding rice landraces of the eastern part of India at germination and seedling stage for low-to-moderate salinity stress tolerance. The germination percentages of 12 high-yielding varieties were analyzed under seven different concentrations of salt (0, 50, 100, 150, 200, 250 and 300 mM). Although, Lalat performed very well with 63.66 % germination rate at 300 mM salt stress conditions, higher levels of salinity exhibited detrimental effects on other varieties. Hence, the salt concentrations 150 mM and 250 mM were optimally selected to screen the varieties for physiological and biochemical traits. The high-yielding varieties Lalat, Vamsi and Pratiksha exhibited lowest and similar trend of reduction over control (ROC) with relative water content (RWC) for 250 mM salt concentrations. The level of proline, increased with increasing concentrations of NaCl among most of the varieties and significantly high content was found in Vamsi. The chlorophyll content was high in Lalat as well as Pratiksha and reduction over control was highest in Vamsi under 150 mM salt concentrations. Interestingly, Lalat emerged as the most salt-tolerant landrace for physiological and biochemical traits. It was compared with salt-sensitive MTU7029 for anatomical changes on adaxial surface of the leaf blade and noticed out to be with less widened and few number of stomatal pores in response to salt stress. Further, expression analysis of salt-specific genes OsHKT1;5 and OsNHX1 resulted in identification of novel salt-stress responsive alleles/motifs like W-boxes, Box-W1, E2Fb and MBS in Lalat (salt-tolerant). Thus, the study disclosed the anatomical changes in adaxial surface of leaf and association of potential cis-acting regulatory elements (CARE) in regulation of salt-stress responsiveness in these two-contrasting rice landraces in the eastern part of India. Further, the study laid a foundation to explore transcriptional gene regulation to open-up the pathway towards crop improvement for salt-stress tolerance.
Many nations have very low standards of living due to rapid growth of population. Most
people lead miserable and very hard lives only because they are not aware of the innovative
knowledge to look for better ways to effectively deal with their problems. The modern tools
of information technology and telecommunications have key role to provide reliable, easy –
to –access and timely information to farmers. Online activity monitoring system can help
farmers to keep a watch on some important parameters like the health condition of the
individual cattle, the behavior changes of cattle for some illnesses and the timely treatment
of sick cattle. In this paper the main focus is to monitor the activity of cattle using
accelerometer sensor.
This paper describes the selection of polymer composite material used for a horizontal axis
wind turbine blade is done using ANYSYS software and consists of two main parts. The
part one consists of computational fluid dynamic simulation of the flow of fluid around the
blade geometry to find the pressure load acting on the wind turbine blade because of the
wind. The second part consists of a finite element analysis of the blade to find the
deformation and stress distribution because of pressure load and blade rotation. A study of
six different materials is done . The present work is to select appropriate composite
material to manufacture the wind turbine blade based on total deformation, stress
distribution and maximum equivalent stress (von-Misses).
