Parametric Analysis of Electrochemical Discharge Drilling on Soda-Lime Glass Material Using Taguchi L27 Orthogonal Array Method

Abstract

The Electrochemical discharge machining (ECDM) is a hybrid non-traditional process which is specifically used for machining of conducting as well as non-conducting materials. In this research work, the fabricated ECDM experimental setup was used to machine the Soda-lime glass material with Brass tool material. The experiments were done on Soda-lime glass material with the help of Taguchi L27 orthogonal array method and analysed by using MINITAB 17 software. The average hole diameter and average machined depth results were checked after ECDM drilling on Soda-lime glass material with considering the input process parameters such as an electrolyte concentration, voltage and rotation. The experimental results indicated that voltage was the most dominant factor for average machined depth followed by an electrolyte concentration and rotation speed. The rotation speed was the most dominant factor for average hole diameter followed by voltage and electrolyte concentration.

Folk medicine used for the treatment of gynaecological disorders in rural areas of Bhadrak district, Odisha, India

Abstract

Panda T., Mishra N., Rahimuddin S., Pradhan B.K., Rout S.D., Mohanty R.B., 2018: Folk medicine used for the treatment of gynaecological disorders in rural areas of Bhadrak district, Odisha, India. - Botanica, 24(2): 132-142. Folk knowledge of the people in a given community has developed over time and is based on experience often tested over centuries of use, adapted to the local culture and environment and held by individuals or communities. This knowledge on resource utilization by human beings for medicinal purposes might have been established by trial and error, accumulated over thousands of years and often becomes encoded in everyday cultural practices. This study addresses an ethno-medicinal investigation in the interior of Bhadrak district, Odisha, India to explore, document and preserve the traditional knowledge for therapeutic use against gynaecological disorders by local inhabitants. The study is primarily based on field surveys carried out in villages, where traditional healers provided information about plant species used as medicine. Data on the use of medicinal plants were collected using standard procedures. A total of 38 medicinal plant species belonging to 29 families were gathered and documented throughout the study period to cure gynaecological ailments of human being. The predominant families are Fabaceae, Apocynaceae and Amaranthaceae. The most widely accepted plant species for the management of gynaecological ailments are Achyranthes aspera, Adhatoda vasica, Asparagus racemosus, Boerhavia diffusa, Moringa oleifera, Phyllanthus emblica, Piper nigrum, Saraca asoca, Trigonella foenum-graecum and Zingiber officinale.
