APPLICATION OF AIR POLLUTION TOLERANCE INDEX IN ASSESSING THE AIR QUALITY

Objective: The rapid growth of urban population both natural and through migration, has put heavy pressure on air quality of an urban area through increase in industrial sectors. The increase in vehicular movement and industrial activities results in significant increase in air pollution. Air quality has been worsened in the major metropolitan cities of India and there are various studies evolving to control and mitigate this problem. One of the studies among several, is on the use of plant as both monitoring and assessment tool. Evaluating the application of Air pollution tolerance index is to assess the ambient air quality and for development of green belt.Methods: A literature search has been done on Scopus scientific database to review the existing knowledge. A variety of search keywords are used related to air pollution tolerance index study. There are total of 63 studies has been published related to Air pollution tolerance index and they were classified based on study area and other parameter.Results: The review has found several pathways to link the air pollution and plant. There are scientific evidence that plants can bio accumulate the air pollutant. The recommendation and suggestions have been provided to carry out further research works based on the limitation found in existing knowledge.Conclusion: These research findings provide an understanding or view about identification of tolerant species and sensitive species in any study area so that these species can be used for a green belt development to prevent the air pollution problems.Â

A concise enantioselective synthesis of (R)-(+)-goniothalamin oxide, a trypanocidal active agent via L-prolinol catalyzed asymmetric epoxidation of cinnamaldehyde

393-398A short and straight-forward enantioselective synthesis of (R)-(+)-goniothalamin oxide 2 has been achieved with an overall yield of 39% and 99% ee. The synthetic approach involves l-prolinol catalyzed asymmetric epoxidation of cinnamaldehyde followed by Lewis acid-mediated diastereoselective allylation of epoxy aldehyde as the key chiral-inducing steps

Ortega-Garcia, "One-handed Keystroke Biometric Identification Competition", in International Conference on Biometrics, ICB 2015, 58-64This work presents the results of the One-handed Keystroke Biometric Identification Competition (OhKBIC), an official competition of the 8th IAPR International Conference on Biometrics (ICB). A unique keystroke biometric dataset was collected that includes freely-typed long-text samples from 64 subjects. Samples were collected to simulate normal typing behavior and the severe handicap of only being able to type with one hand. Competition participants designed classification models trained on the normally-typed samples in an attempt to classify an unlabeled dataset that consists of normally-typed and one-handed samples. Participants competed against each other to obtain the highest classification accuracies and submitted classification results through an online system similar to Kaggle. The classification results and top performing strategies are described.The authors would like to acknowledge the support from the National Science Foundation under Grant No. 1241585.

P2O5-mediated Friedel-Crafts acylation of activated arenes with carboxylic acid as acylating agent

1861-1867P2O5 has been found to be a highly efficient and environmental friendly catalyst for the liquid-phase acylation of activated aromatic substrates giving aromatic ketones (45-93%) in a regioselective manner. Both aromatic and aliphatic carboxylic acids can be employed as acylating source. The process is particularly demonstrated at 100 g scale in the case of anisole and acetic acid to produce 4-methoxyacetophenone

Oxidative Cleavage of Alkene C=C Bonds Using a Manganese Catalyzed Oxidation with H2O2 Combined with Periodate Oxidation

A one-pot multi-step method for the oxidative cleavage of alkenes to aldehydes/ketones under ambient conditions is described as an alternative to ozonolysis. The first step is a highly efficient manganese catalyzed epoxidation/cis-dihydroxylation of alkenes. This step is followed by an Fe(III) assisted ring opening of the epoxide (where necessary) to a 1,2-diol. Carbon-carbon bond cleavage is achieved by treatment of the diol with sodium periodate. The conditions used in each step are not only compatible with the subsequent step(s), but also provide for increased conversion compared to the equivalent reactions carried out on the isolated intermediate compounds. The described procedure allows for carbon-carbon bond cleavage in the presence of other alkenes, oxidation sensitive moieties and other functional groups; the mild conditions (r.t.) used in all three steps make this a viable general alternative to ozonolysis and especially for use under flow or continuous batch conditions

A Selective, Efficient and Environmentally Friendly Method for the Oxidative Cleavage of Glycols

A catalytic methodology for the oxidative cleavage of vicinal diols is described as an advantageous alternative in terms of the environmental impact on classical methods involving toxic oxidants. The novel strategy is based on the use of dioxomolybdenum(VI) complexes as catalysts and dimethyl sulfoxide (DMSO) as an oxidant and displays high selectivity and a broad scope for glycol cleavage. In addition, the developed system is also useful for the oxidation of acyloins to diketones.Ministerio de Economía y Competitividad (MINECO) and FEDER (CTQ2013-48937-C2-1-P) and Junta de Castilla y León (BU237U13

Beyond the Classroom Walls: Role of Social Media in Information Transfer

Teaching is the creative process of imparting knowledge and skills. Data and information are required to substantiate the teaching process and the effectiveness depends on the individual’s creativity. The technological development in information sharing has created tremendous changes in education. The ability to search any specific information with less time, customized reproducibility of information, significant reduction in space requirement for carrying information and realistic audio visual form of information has grounded a strong foundation for modern education process. The arrival of social network sites which incorporate all above mentioned features has further simplified the teaching process. The present article deals with the role of social media in facilitating improved access to information
