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.

The study of the rectangular microstrip patch antenna characteristics is presented here. For the 2.45 GHz frequency, the patch antenna design dimensions are optimized for the value 58 × 41.36 mm and simulated in IE3D software for different thickness, dielectric constant, feed and a slit made on it. Simulation results of all the proposed patches show the S-parameter value of S11 <-10 dB and voltage standing wave ratio, VSWR < 2. The resonant bandwidth of frequency is tabulated with the return loss. The slit patch gives multiband characteristics. All this study gives an idea of microstrip patch antenna characteristics. This type of antenna is useful in wireless communication applications, such as WLAN, Bluetooth. © 2012 Praise Worthy Prize S.r.l.-All rights reserved.

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.

Owing to the increasing cost of petroleum products, fast depletion of fossil fuel, environmental consideration and stringent emission norms, it is necessary to search for alternative fuels for diesel engines. The alternative fuel can be produced from materials available within the country. Though the vegetable oils can be fuelled for diesel engines, their high viscosities and low volatilities have led to the investigation of its various derivatives such as monoesters, known as bio diesel. It is derived from triglycerides (vegetable oil and animal fates) by transesterification process. It is biodegradable and renewable in nature. Biodiesel can be used more efficiently in semi adiabatic engines (Semi LHR), in which the temperature of the combustion chamber is increased by thermal barrier coating on the piston crown. In this study, the piston crown was coated with ceramic material (TiO2) of about 0.5 mm, by plasma spray method. In this present work, the experiments were carried out with of Pongamia oil methyl (PME) ester and diesel blends (B20 & B100) in a four stroke direct injection diesel engine with and without coated piston at different load conditions. The results revealed 100% bio diesel, an improvement in brake thermal efficiency (BTE) and the brake specific fuel consumption decreased by about 10 % at full load. The exhaust emissions like carbon monoxide (CO) and hydrocarbon (HC) were decreased and the nitrogen oxide (NO) emission increased by 15% with coated engine compared with the uncoated engine with diesel fuel. The peak pressure and heat release rate were increased for the coated engine compared with the standard engine. © 2013 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

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.
