    The asymmetric unit of the title compound, C19H20N2O3, contains two independent mol­ecules in both of which the pyrrolidine ring adopts an envelope conformation, but with a C atom as the flap in one mol­ecule and the N atom in the other. The pyran ring adopts a half-chair conformation in both mol­ecules. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds and C—H⋯π inter­actions

    In the title compound, C5H7N2 +·C6H2N3O7 −, there are two crystallographically independent cations and anions (A and B) in the asymmetric unit. In both picrate anions, one of the nitro groups lies in the plane of the benzene ring [r.m.s. deviations = 0.014 (2) and 0.014 (2) Å for anions A and B, respectively] and the other two are twisted away by 39.0 (2) and 18.8 (2)° in A, and 18.2 (1) and 2.5 (2)° in B. In the crystal, the cations and anions are linked by inter­molecular N—H⋯O and C—H⋯O hydrogen bonds, forming a two-dimensional network

    The mol­ecular conformation of the title compound, C15H10ClN3, is stabilized by an intra­molecular N—H⋯N hydrogen bond with an S(7) ring motif. The crystal packing is controlled by N—H⋯N and C—H⋯N inter­molecular inter­actions. One of the methyl­ene groups of the cyclo­hexene ring is disordered over two positions with refined occupancies of 0.457 (12) and 0.543 (12)

    The present investigation was conducted to find out the antimicrobial, hemolytic activity and protein content of fish epidermal mucus and their chemical constituents from Anabas testudineus. The in vitro hemolytic activity were analyzed and the antimicrobial activity against human pathogens (Bacteria) were determined by agar well diffusion methods. Epidermal mucus sample protein was analyzed by (Thin layer chromatography and SDS-PAGE). Totally thirteen human pathogens were tested against the fish mucus. Out of thirteen pathogens five pathogens have proved to be sensitive to the mucus. The average value of maximum zone of inhibition was observed against K. pneumonia (15.17±0.09mm) > P. vulgaris (13.2±0.17mm) > E. lentum (12.43±0.18mm) > MRSA (11.37±0.32mm) > S. aureus (10.5±0.11mm). The percentage of haemolysis for lyophilized sample shows more hemolytic activity. The amount of protein present in the mucus for Lyophilized sample: 3.61 g/dL, for Rotavac sample: 1.08 g/dL. The present inspection were revealed that positive progresses in the fish mucus extracts hostile to human pathogen (Bacteria) and the hemolytic activity, also the simple population of proteins (SDS PAGE) and the (TLC) reveals the presence of amino acids and peptides. Further efforts are required for the isolation of the active antimicrobial compounds in order to establish their possible applications

    Purpose: The economic liberalization and globalization have brought a fervent environment for the common and small investors who are willing to participate in the various investment avenues available in India. There are large number of small investors, who have the ability to save and make an investment in share market, gold, real estate, insurance and post office. In recent years, numerous researches have been conducted on investors’ perception towards various investment from various perspectives. From a survey on investment literatures of equity, insurance, and mutual fund perspective, there are some studies based on the investment on various avenues made by researchers. However, the investors’ perception towards various investment avenues in Vellore city, Tamil Nadu and India is yet to be explored. This article is therefore timely and fills the gap in investment avenues literature. Furthermore, by pooling small amounts of money into a single investment value, individual investors are able to participate in investment strategies that would have otherwise been financially unfeasible. The Indian investment industry is witnessing a rapid growth as a result of infrastructural development, manufacturing and service sector, in personal financial assets and rise in foreign participation. With the growing risk appetite, rising income, and increasing awareness. Mutual funds and shares are becoming a preferred investment vehicles like bank fixed deposits and post office savings that are considered safe. The present empirical study is an attempt to examine the investors’ perception towards various investment avenues in Vellore city, Tamil Nadu, India. Design/Methodology/Approach: Primary data using convenient sampling through questionnaire and interview method as well as secondary data from wide range of literature from various journal publications had been utilized. Frequency distribution, percentage analysis, Mann Whitney and Kruskal-Wallis Test were used to test the objectives of the study. In order to test the reliability of the scale, the researchers applied Cronbach’s Alpha (CFA) to measure the internal consistency of the variables. Findings: The findings of the study on investors’ perception towards various investment avenues emphasized that the aged and high income investors prefer to invest only in post office and bank deposits for safety investment reason. Originality/Value: An Empirical Analysis on Investors’ perception towards various investment avenues in Vellore city, Tamil Nadu and India is the original work of the authors.

    The title compound, C32H23ClN2O4, has a quinoline, a chloro­phenyl and an acenaphthalene ring system attached to a central pyrrolidine ring, which has three stereogenic centers. Nevertheless, the compound crystallizes as a racemate with two mol­ecules of identical chirality in the asymmetric unit. They differ in the conformation of the five-membered pyrrolidine ring; in one molecule it has an envelope conformation, while in the other molecule it has a twisted conformation. In each molecule there is an intra­molecular O—H⋯O hydrogen bond making an S(6) ring motif. In the crystal, pairs of N—H⋯O hydrogen bonds produce inversion dimers with R 2 2(8) motifs. There are also C—H⋯O interactions present. The crystal structure contains voids (60 Å3) within which there is no evidence of solvent mol­ecules
