Churn Prediction using MapReduce and HBase.

The mobile telecommunication market is rapidly increasing with numerous service providers stepping in the market. This makes the customer think to leave the service provided by one service provider and move to another service provider for some better offers. This project is an attempt to design and implement an application that can take Customer Records as input and give Customer churn prediction details as output. It will enable service provider to know in advance about the valuable customer who are about to churn. By merely giving customer data records as input, user can get the desired customer behaviour pattern, which is the churn output. The output obtained will basically distinguish the churners and the non-churners. The system is built using Apache Hadoop, Apache HBase and a Data Mining Algorithm under MapReduce code. The use of Hadoop framework makes it easy to process the large datasets containing the information of customers. DOI: 10.17762/ijritcc2321-8169.150317

Sustainability of bioplastics: opportunities and challenges

Recycling is groundwork of the worldwide efforts to diminish the amount of plastics in waste. Mostly around 7.8–8.2 million tons of poorly-used plastics enter the oceans every year. Non-biodegradable plastics settlements in landfills are uncertain, which hinders the production of land resources. Non-biodegradable plastic solid wastes, carbon dioxide, greenhouse gases, various air pollutants, cancerous polycyclic aromatic hydrocarbons and dioxins, released to the environment cause severe damage and harmfulness to the inhabitants. Due to the bio-degradability and renewability of biopolymers, petroleum-based plastics can be replaced with bio-based polymers in order to minimize the environmental risks. In this review article, bio-degradability of polymers has been discussed. The mechanisms of bio-recycling have been particularly emphasized in the present article

Recent approaches in guar gum hydrogel synthesis for water purification

Guar gum based hydrogels have evoked great attention in research as well as in industry for exploring miscellaneous applications in the field of water purification, medicine, agriculture, explosives, cosmetics, textile, paper, and food to name a few. In this article, latest modifications for developing guar gum based hydrogels and composite materials for water purification application are extensively reviewed. Regenerative nature of Guar gum hydrogels makes it a better choice for treating wastewater as well as other value-added applications. Moreover, nonionic nature makes guar gum an acceptable material for further modifications. In this article, we also present a brief discussion on structure and properties of guar gum

Recent progress in sodium alginate based sustainable hydrogels for environmental applications

Recently, there is a growing research interest in the applications and development of novel sustainable hydrogel materials in waste water treatment because of radically distinctive chemical and physical characteristics of hydrogels such as hydrophilicity, swell ability and modifiability to name a few. Hydrogels have exposed the hypernym functioning in the removal of a wide range of aqueous pollutants containing toxic dyes and heavy metal ions. A large amount of water gets incorporated in the three dimensional networks of hydrophilic structures of hydrogels. The prime objective of this review article is to render a presentation on the recent advances in the modifications of sodium alginate based hydrogels for the adsorptive removal of toxic pollutants. In addition, article also briefly gives the classification and properties of hydrogels and alginate

Expression and Characterization of Chandipura Virus Proteins

Chandipura virus (CHPV) has recently emerged as an extremely lethal human pathogen in the family Rhabdoviridae and is linked to significant encephalitis outbreaks in different parts of India. The biology of CHPV remains less studied to date and the availability of reagents such as purified proteins can enhance research in this direction. In this study, we have overexpressed four of the CHPV proteins namely Nucleoprotein (N), Phosphoprotein (P), Matrix protein (M) and Glycoprotein (G) using three  distinct tags in bacterial system and with changes in inducer concentration, growth and solubilisation conditions successfully purified M and G proteins for the first time along with N and P. Furthermore, the interactions of CHPV M protein with other viral proteins (G, N and P) was investigated using ELISA and GST pull down assays to show the utility of olubilised proteins. The results of both the assays demonstrated that M protein interacts with both G and N proteins, while it does not interact with P protein, in a similar  manner as reported for Vesicular Stomatitis Virus

Progress in pectin based hydrogels for water purification: trends and challenges

Pectin is one of the finest natural polymer which has drawn great attention because of its applications in different fields. Due to the quintessential structure of pectin, it can be transformed into variety of useful products. It can be utilized as a blend in many polymers to make a mixture or a composite material. Owing to considerable collection in chemical conformation and cross-linking mechanism, different pectin based hydrogels have been prepared for different characteristics in pharmaceutical and bio-medical sites. Inventive properties of hydrogels like volubility, swellability, solvability and hydrophilicity make them better alternative for wastewater treatment. Recently, pectin based hydrogels have demonstrated excellent performance to eliminate various metal ions and dyes from the polluted water. The adsorption characteristics of pectin based hydrogels can be upgraded by using nanoparticles, which prompts to the development of hydrogel nano-composites. In this review article, we have summarized a comprehensive assessment in the direction of using pectin based hydrogels to remove toxic pollutants from aqueous solution. Sodium acrylate-co-N-isopropylacrylamide based pectin hydrogel has demonstrated the maximum adsorption capacities of 265.49, 137.43, 54.86, 53.86, 51.72 and 50.01 mg g−1 for the adsorption of methyl violet, methylene blue, Pb(II), Cu(II), Co(II) and Zn(II) respectively. We have also discussed the pectin structure, properties and applications in this article

Mitochondrial DNA analysis of critically endangered Chinese Pangolins (Manis pentadactyla) from Nepal

Chinese Pangolins (Manis pentadactyla) are Critically Endangered and one of the most illegally traded mammals globally. We generated first COI sequences from five individuals of this species from Nepal. BLASTn search of our 600bp sequences at GenBank showed pair-wise identity between 99.17% and 100% to M. pentadactyla. There were three haplotypes and a total of five variable sites among five M. pentadactyla sequences. Neighbor-joining tree revealed that all M. pentadactyla from Nepal clustered into same group further splitting into two sub-groups albeit with low bootstrap value, suggesting potential multiple geographic origins. The K2P distance was 0.3% within group and 0.7% between four sequences from Bhaktapur and Kavrepalanchok districts (Mape2, Mape3, Mape5 and Mape6) and museum sample (Mape10). This study has generated reference samples for M. pentadactyla from Nepal and will be helpful in understanding dynamics of illegal trade of this species and in successful identifi- cation of M. pentadactyla from Nepal even in the absence of intact specimens

Coping with Illness: Insight from the Bhagavad Gita

The Shrimad Bhagavad Gita enlightens everyone on how to cope up with various situations in life. It uses the conversation between Lord Krishna and Arjuna to highlight initial negative coping mechanisms exhibited by the latter. It goes on to showcase positive coping skills suggested by Lord Krishna and implemented by Arjuna. The Bhagavad Gita, through this case-based methodology, teaches us how to cope with a demanding situation. Diabetes is a lifestyle disease, which warrants a thorough change in one\u27s lifestyle, including changes in basic activities such as diet and exercise. This brief communication utilizes the teachings of Bhagavad Gita to help in coping with illness, especially chronic illness such as diabetes. The article cites verses from the Bhagavad Gita to show how one may cope with the stress of illness such as diabetes
