In this experimental work, an attempt has been carried out to decide the optimized parameters namely diameter of wire, on/off pulse time, current, tension in wire for minimizing surface roughness (SR) & for maximizing MRR (metal removal rate) during machining by wire electrical discharge (WEDM) process of Titanium Grade 2 (Ti Gr 2) alloys. Ti Gr 2 alloys are widely employed in fabrication of various aerospace components because of their low weight ratio, high strength and superior resistance to corrosion. This paper discusses in detail about optimizing process parameters of WEDM including SR and MRR related with the corner machining mechanism employing Taguchi technique. Ti Gr 2 alloy components were machined using WEDM at various process control combinations obtained by means of Taguchi technique algorithm. The optimized process parameters were experimentally observed to yield high quality of surface finish, increased corner accuracy & high rate of material removal. © 2017 Elsevier Ltd.

Biodiesel, an alternative fuel is derived from the fats of animals and plants. As energy demands increase and fossil fuels are limited, research is directed towards alternative renewable fuels. The main advantages of using this alternative fuel are its renewability, biodegradability and better quality of exhaust gases. It is technically competitive and environmentally friendly alternative to conventional petro-diesel fuel for use in Compression Ignition (CI) engines. The use of biodiesel reduces the dependence on imported fossil fuels which continue to decrease in availability and affordability. An experimental investigation has been carried out to evaluate the combustion, performance and emission characteristics of a diesel engine with the effect of using neem oil methyl ester and its diesel blends at different loads. The results showed that maximum cylinder pressure and maximum rate of heat release increased with the increase in bio diesel blends. The carbon monoxide (CO) and smoke emissions were found significantly lower when operating on biodieseldiesel blends, but Nitrogen Oxide (NOx) emissions are found to be higher at full load. © 2013 Science Publication.

African marigold (Tagetes erecta) has been used for medicinal purposes since prehispanic times. The various parts of the plant such as stem, leaf, flower and root were subjected to analysis the qualitative phytochemical constituents with two different solvents (ethyl alcohol and petroleum ether). About sixteen phytochemicals analysis were carried out, out of which six phytochemicals were identified in both the solvents predominantly.

Technology is a tool in learning process. Learning English is a prestigious process. Communicating in English gives social status. It is felt difficult by most of the learning community owing to their inveterate habit of speaking only in their respective mother tongue. Communication could be achieved by acquiring four language skills such as listening, speaking, reading and writing. Learning English as second language to speak, read and write is very difficult for learners hailing from the rural areas.

A designing pattern provides generic idea of a solution to solve a recurring problem with variety of goals and constraints. In object oriented program, design patterns are recognized by source code. This paper provides overall idea about design patterns, different types of analysis and their comparison details with detection techniques of pattern. It also explains how it is related with non functional requirements in improving the quality of pattern. © 2014 IEEE.

Herbs are considered to be the backbone of traditional medicines from Hispanic days. About 80% of the World's population depends on the traditional medicines for various ailments. With this background, the present investigation was concentrated on the screening of bioactive components of Tagetes erecta L. The GC-MS analysis of dried leaves and flower samples were carried out using GC-MS-QP 2010 model with methanol as solvent. Around 19 and 31 phytochemicals were registered in leaf and flower samples, respectively which have high therapeutic value in the commercial available drugs.

Ipomoea batatas (L.) Lam, also known as sweet potato, is an extremely versatile and delicious vegetable that possesses high nutritional value. It is also a valuable medicinal plant having anti-cancer, antidiabetic, and anti-inflammatory activities. Sweet potato is now considered a valuable source of unique natural products, including some that can be used in the development of medicines against various diseases and in making industrial products. The overall objective of this review is to give a bird's-eye view of the nutritional value, health benefits, phytochemical composition, and medicinal properties of sweet potato. Specifically, this review outlines the biological activities of some of the sweet potato compounds that have been isolated, the pharmacological action of the sweet potato extract, clinical studies, and plausible medicinal applications of sweet potato (along with a safety evaluation), and demonstrates the potential of sweet potato as a medicinal food. © 2014 Mary Ann Liebert, Inc.

A comparative study was done on the production of 4-ipomeanol from root tubers of Ipomoea batatas and its rhizogenic callus. Best callusing response was obtained on MS medium supplemented with 11 μM NAA (α-Naphthaleneacetic acid) and 1 μM KIN (Kinetin). Effect of various elicitors (Fusarium solani, chitin and chitosan) on the production of 4-ipomeanol was studied. Methanol extract of the samples were purified by column chromatography and detected using TLC. Identification of 4-ipomeanol was confirmed using HPLC and quantified spectrophotometrically. A mass spectrum was recorded to confirm the presence of 4-ipomeanol. The calli grown under chitin produced highest (6.61mg g-1) amount of 4-ipomeanol. This is the first report on in vitro production of 4-ipomeanol from I. batatas. Since 4-ipomeanol is reported to be present only in I. batatas, this study would help in standardizing protocols for large scale production without affecting its natural flora. © 2015, National Institute of Science Communication.

The present work, the leaves of Gherkin (Cucumis Sativus) treated with sulphuric acid and formaldehyde were used as an adsorbent for the removal of acid blue, acid red and malachite green from aqueous solution. The adsorption characteristics of all the three acid dyes on activated Gherkin leaf powder (GLP) were evaluated as a function of pH, adsorbent dose, initial concentration of adsorbate, temperature. The effective adsorption was found to be in pH range 3.4 to7.1, adsorbent dose 0.5g to 0.8g, initial concentration (1 x 10-5 to 5 x 10-5M) and Temperature range (308 to 318 K). The results reveal that maximum adsorption of all three acid dyes onto GLP is within the range of 59.80% to 71.0%. The adsorption data fitted well into Freundlich and Langmuir adsorption models. The results show that Gherkin leaf powder holds a great potential in removal of acid dyes from industrial wastewater.
