Guide to the Dewey Decimal Classification scheme

This library uses the Dewey Decimal Classification scheme (DDC) to arrange books and other library materials on the shelves for easy retrieval. It is used in many libraries and allows items about the same subject to be shelved together. This is a guide to the numbers used and what they represent

Physical verification as administrative and collection evaluation tool: A study ofInstitute of Agriculture Library; Visva-Bharati

This article is the result of an intensive stock verification of more than 50000 documents of an academic library(Institute of Agriculture; Visva-Bharati) established in 1957. The physical verification process includes physical noting of all accession number of books on and out of stack and use of LibSys software to generate reports. The paper highlights that physical verification of collection can help in identifying major areas of loss and thereby can help in framing administrative guideline for collection evaluation and management policy. The paper also urges for review of existing government rules regarding the loss of books and weed-out policy

Electronic Publishing in Higher Education: How to design OAI interfaces - Recommendations -

The Open Archives Protocol for Metadata Harvesting (OAI-PMH) allows sharing metadata serving to describe arbitrary objects with others. In addition to a short overview of the protocol the paper on hand contains recommendations for the application of Sets by German data providers and for the proper usage of the metadata elements of Dublin Core (DC). Thereby the target is pursued to ensure an efficient metadata exchange between the different users of the OAI protocol

Role of B-ring of colchicine in its binding to tubulin

The chemical specificity of the colchicine-binding site of tubulin is less stringent for the presence of the B-ring than the A- and C-rings of colchicine, Colchicine analogues with modifications in the B-ring bind to tubulin at the same site as colchicine. Analogues with smaller or no substituents in the B-ring bind tubulin remarkably faster than colchicine. Thus, a compound without the B-ring [2-methoxy-5-(2',3',4'-trimethoxyphenyl)tropone] binds tubulin even at 4 °C and the binding is almost instantaneous at 37 °C. Colcemid and 2-methoxy-5-(2',3',4'-trimethoxyphenyl)tropone bind reversibly to tubulin, whereas colchicine and desacetamidocolchicine bind almost irreversibly, suggesting that the size of the B-ring moiety of colchicine is not related to the reversibility of binding. We conclude that although the presence of the B-ring of colchicine does not appear to be an essential prerequisite for the drug-tubulin interaction, the B-ring substituents play an important role in determining the binding properties of colchicine to tubulin

Computational analysis of bacterial sulfatases and their modifying enzymes

AbstractThe sequence analysis of enzymes that might modify bacterial sulfatases should be useful in the task of identifying the human sulfatase-modifying homologs — enzymes that are defective in the rare inherited disease multi-sulfatase deficiency

Evaluating the environmental and economic impact of fruit and vegetable waste valorisation: The lettuce waste study-case

The fruit and vegetable sector generates large amounts of waste, which poses both environmental and economic issues. Different strategies can be applied to valorise fruit and vegetable waste (FVW) by turning it into value-added products. However, the economic and environmental impact of such strategies is largely unknown. In this paper, the environmental and economic impact of FVW valorisation on an industrial scale was evaluated by developing a Decision Support System (DSS). To this aim, the lettuce waste study-case was considered, since different innovative laboratory-scale strategies have been recently proposed for its valorisation. Investment and running costs, energetic demand and yields of lettuce waste valorisation processes were collected based on laboratory tests and industrial surveys. The application of the DSS estimated that if 30% of lettuce waste annually produced by a large company was valorised by using a system configuration that involves not only anaerobic digestion and composting, but also high pressure homogenisation to produce fresh juices, and ultrasound-assisted extraction to produce antioxidant extracts, this configuration would lead to an investment lower than 10 million \u20ac, a 1 year-pay-back time and a 72 tons-reduction of carbon dioxide emissions, thus representing a rational compromise between economic returns and environmental advantage. The developed multi-objective DSS is a valuable tool to identify the most sustainable and investment-worthy processes for the valorisation of FVW
