Cashew and apple nectars: Brazilian consumers can trust in labels?

Apple and cashew nectars are well accepted by Brazilian consumers and promise important sources of bioactive compounds. The aim of this study was to determine the physicochemical characteristics of cashew and apple nectars of different brands and compare them with Brazilian Legislation. Analysis was made in triplicate for pH, Brix, acidity, ascorbic acid, anthocyanin, the ratio of total solids to citric acid in the case of cashew nectars, and to malic acid in apple nectars and total carbohydrate content.

Development of biotechnology of dye & drug plant indigofera variety «feruz -1» for the improving of saline lands of the aral sea basin

The possibility of developing of biotechnology and agrotechnology of indigofera plants in ecologically salted and degraded lands of the Aral Sea region was studied. A new salt-resistant variety of indigofera “Feruz-1” and its agrotechnology of cultivation and biotechnology for obtaining of drug & dye pigment indigo has been developed. Quantitative and qualitative HPLC method of determination of indigo dye has been developed.

Effect ofplant growth regulators on micropropagation and rooting of the regenerated plant-lets derived from wheat (triticum aestivum l.) embryogenic callus

A simple method was developed for direct shoot regeneration of wheat (Triticumaestivum L.). Various types of plant growth regulators singly or in combinations were investigated. Regenerated plantlets from wheat embryogenic callus were placed in MS medium supplemented with different types and concentrations of growth regulators.

Interaction of plasma medium with electromagnetic waves

The electrical properties of plasma are important in applications of electromagnetic are the conductivity, electrical permittivity and magnetic permeability. With these parameters known, propagation of electromagnetic waves in plasma can be inspected thoroughly. Since ions and electrons are the constituents of plasma, interaction of electromagnetic waves with the plasma can be formulated by starting from the behavior of a single charged particle under the effect of an electromagnetic wave. Throughout this paper, theory of interaction of electromagnetic waves with plasmas is introduced.

Spectrophotometric determination of chromium in water, rice and vegetable samples

Chromium (VI) has been determined with 1,5-diphenylcarbazide under conditions like pH = 1.65; the ratio of nDPC/(nCr(VI)) = 2.18 (by mol); The calibration curve for determination of chromium was also established as A = (0.8324 ± 0.00901).CCr + (0.0086 ± 0.00506). The total chromium in the water, rice and water spinach was analyzed. The obtained results of chromium concentrations in these samples showed that the samples were not polluted by chromium.

Hydropower dam impact on the environment and livelihood in the Mekong river basin

Hydropower is a renewable energy source, but can have huge impacts on freshwater ecosystems, fisheries, and flood dependent agriculture. New hydropower dams have already threatened some of the world’s most ecologically diverse river basins such as the Amazon, the Zambezi and the Mekong. They may partially dehydrate the landscapes and influence the surface and the groundwater systems. River dynamics may suffer major modifications, particularly in runoff distribution change.

News contextualization using web scraping techniques and api(s)

Getting different views and articles about any specific news, from different sources, can be done by news contextualization. The solution for news contextualization would be integrating all the textual and pictorial information about the news topic, that can be found on various social networking sites and news sites, and, displaying them all in a single place. Taking a search keyword from the user and retrieving the related news data from different news sources and social networking sites can be done by web scraping techniques and/or using ‘APIs’.

Collaborative information behavior from perspectives of information seeking and sharing in academic settings

The focuses of paper are on the understanding of collaborative information behavior (CIB)and literature review in models of CIB. This paper also analyzes the role of academic libraries in supporting CIB within academic communities. The methodology was used in this paper is analyzing literature review and theoretical discussion on CIB. The purposes of paper are to understand how information behavior in collaborative contexts is defined, and what models of CIB are used in practice.

Privatization of higher education in India- issues, challenges and sugestions

In size India has third largest higher educational system in the world, next to China and to United States. It grows rapidly after independence. In terms of the number of educational institutes, India has an upper rank in the world. It consists of three phases as funding, philanthropic to public and then to private financing. Changing patterns have altered regulations, equity, efficiency and quality of higher education. Indian society is a mixed society consisting of a large number of haves and a same number of have-nots.
