E-commerce Portal with Live Chat

e-commerce is the most visible business use of the World Wide Web. E-commerce site is use to sell products online This project deals with developing an e-commerce portal. a collection of different product provided to user for buying in the store. To simplify online purchase a shopping cart is provided to the user. Advantage of e-commerce over traditional commerce is the user can browse products online and shops, compare prices of same product on different websites and order merchandise sitting at home. These days hundreds of e-commerce websites are available but hardly any of them provides all the functionalities that an ideal e-commerce portal should provide. The idea is to build a complete e-commerce portal on Magento platform. For increasing the use of e-commerce in developing countries the business to Business e-commerce is implemented. Magento is enterprise-class eCommerce platform offering powerful and flexible features. Magento standout amongst the best full featured e-commerce systems accessible in both the restrictive and open source markets. It gives all that you have to deal with an entire business, including promotions and stock administration. Magento features intensify user experience and increase selling potential

Surface activation of polyester fabric using ammonia dielectric barrier discharge and improvement in colour depth

The effect of atmospheric pressure ammonia dielectric barrier discharge on the surface of polyester fabric has been studied using contact angle goniometer, ATR–FTIR spectroscopy and SEM. It is observed that the surface of plasma treated polyester is more hydrophilic due to incorporation of nitrogenous polar functional groups and shows different conformational composition and crystallinity. The ATR–FTIR results clearly indicate the conversion of trans ethylene glycol residue to gauche one after plasma treatment and thus reduction in crystallinity. Plasma treatment has shown synergetic effect on dye uptake. Natural dyeing of plasma treated polyester with ‘Rubia cordifolia’ has shown 65% improvement in colour depth in comparison to untreated polyester fabric

Modeling asymmetric sovereign bond yield volatility with univariate GARCH models: Evidence from India

Does Indian sovereign yield volatility reflect economic fundamentals, or whether it is a self-generated force flowing through markets with little connection to such fundamentals? To answer the question, this research explores the volatility dynamics and measures the persistence of shocks to the sovereign bond yield volatility in India from 1 January 2016, to 18 May 2022, using a family of GARCH models. The empirical results indicate the high volatility persistence across the maturity spectrum in the sample period. However, upon decomposing the markets into bull and bear phases, our results support the existence of weak volatility persistence and rapid mean reversion in the bear market. This shows that the economic response policies implemented by the government during the pandemic, including fiscal measures, have a restraining effect on sovereign yield volatility. For a positive γ, the results suggest the possibility of a “leverage effect” that is markedly different from that frequently seen in stock markets. Results further indicate that the fluctuations in Indian sovereign yields cannot be dissociated from inflation and money market volatility. Our findings herein provide valuable information and implications for policymakers and financial investors worldwide

Dietary polyphenols influence antimetabolite agents: methotrexate, 6-mercaptopurine and 5-fluorouracil in leukemia cell lines

Polyphenols have been previously shown to sensitize leukemia cell lines to topoisomerase inhibitors. Here, we assess the effects of five polyphenols when used alone and in combination with antimetabolites: methotrexate, 6-mercaptopurine and 5-fluorouracil; in lymphoid and myeloid leukemia cells lines, and non-tumor control cells. The effects of combined treatments were investigated on ATP and glutathione levels, cell-cycle progression, DNA damage and apoptosis. Polyphenols antagonized methotrexate and 6-mercaptopurine induced cell-cycle arrest and apoptosis in most leukemia cell lines. This was associated with reduced DNA damage and increased glutathione levels, greater than that seen following individual treatments alone. In contrast, 5-fluorouracil when combined with quercetin, apigenin and rhein caused synergistic decrease in ATP levels, induction of cell-cycle arrest and apoptosis in some leukemia cell lines. However, antagonistic effects were observed when 5-fluorouracil was combined with rhein and cis-stilbene in myeloid cell lines. The effects were dependant on polyphenol type and chemotherapy agent investigated, and cell type treated. Interestingly treatment of non-tumor control cells with polyphenols protected cells from antimetabolite treatments. This suggests that polyphenols modulate the action of antimetabolite agents; more importantly they antagonized methotrexate and 6-mercaptopurine actions, thus suggesting the requirement of polyphenol-exclusion during their use

Development of a mobile application

With the proliferation of Android phones and fast internet connectivity, Android applications can help in targeting a wide audience. The rising trend in social networking has led to an increased usage of internet for keeping in touch with people within a social circle. Different social networking platforms, target at different social circles such as professional or friend circle. This project concentrates on Nanyang Technological University (NTU) student population and helps them connect with each other over the events that occur within NTU.Bachelor of Engineering (Computer Engineering

Anthraquinone glycoside from stem bark, fatty acids and sterols from seeds of <i>Cassia reingera</i>

1970-1971From the bark of Cassia reingera 1,5,6-trihydroxy-3-methyl-anthraquinone-8-O--L-glucoside has been isolated and its structure elucidated with the help of chemical studies and spectral data. The dyeing property of crude anthraquinone has been studied to develop variety of shades on wool by using different mordants. Sterols and fatty acids have been isolated from the seeds of Cassia reingera and are identified by using GLC techniques by comparison with authentic sample

Isolation and characterization of anthraquinones from the stem bark of <i>Cassia siamea</i>

2257-2258Anthraquinone chrysophanol 1 and bianthraquinone Cassiamin 2 have been isolated from the stem bark of Cassia siamea and their structures are elucidated by spectral studies

A review on anthraquinones isolated from <i>Cassia</i> species and their applications

291-319Cassia Linn. (Family <span style="font-family:Symbol; mso-ascii-font-family:" times="" new="" roman";mso-hansi-font-family:"times="" roman";="" mso-char-type:symbol;mso-symbol-font-family:symbol"="" lang="EN-GB">- Caesalpiniaceae) is a large tropical genus with about 600 species of herbs, shrubs and trees. Most of the plants of the genus are wellknown in Indian system of medicine for their cathartic, purgative and antibiotic properties. Many compounds of structural significance and medicinal importance have been reported from different species of this genus. Species of Cassia are rich source of anthraquinones which are wellknown as natural dyes, and are gaining importance in recent years due to environmental pollution caused by synthetic dyes. This paper attempts to give an overview of literature on the isolated and characterized anthraquinones from various Cassia species and their repoted applications. Besides dye yielding properties they are used in cosmetics and pharmaceuticals. Thus plants of Cassia species can serve as commercial source of naturaly occurring anthraquinones. </span
