abstract: the commercial development of food products originated from the plants as sources of antioxidants to increase the health benefit and stabilize the food is of current interest. this study was aimed at obtaining dill extract using cold solvent method by three solvents, (methanol, acetone, and hexane) and examining the antioxidant potency and determining the oxidative stability of sunflo...

background. opportunistic fungal infections like candidiasis are common in the oral cavity. in recent years candida species have shown resistance against a number of synthetic drugs. this study assessed the antifungal activity of centratherum anthelminticum and ocimum sanctum seed oils against six common pathogenic candida strains. synergistic activity of the major oil components was also studi...

Topological control of nanostructures plays a crucial role in understanding the crystal growth process at the nanometer length scale. Here, the scalable synthesis of upconversion materials with distinct hedgehog-like morphologies by a seed-mediated synthetic procedure is reported. It is demonstrated that a close match in the crystal lattice between the core and shell components is essential for...

Effectiveness of different doses of neem extracts and a synthetic organic insecticide against mustard aphid was studied in the experimental farm of the Oilseed Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, during two consecutive years 2010-2011 and 2011-2012 for the control of mustard aphid. Eight treatments were evaluated against mustard aphid under fi...

The bioefficacy of various plant extracts, namely Azadirachta indica A. Juss, Khaya senegalensis Desrousseaux (A. Jussieu) and Hyptis suavuolens (L.) Poit, either alone or in combination with half the recommended dose of synthetic pesticides, was studied with farmers to find a more sustainable strategy for the management of bollworms in cotton. A number of treatments were farmer innovations. Th...

Influence maximization (IM), which selects a set of k users (called seeds) to maximize the influence spread over a social network, is a fundamental problem in a wide range of applications such as viral marketing and network monitoring. Existing IM solutions fail to consider the highly dynamic nature of social influence, which results in either poor seed qualities or long processing time when th...

Successful agriculture depends on high-quality seed, which is a fundamental and important ingredient. Under unfavourable environmental conditions like drought, pre-sowing seed treatment such as coating priming could boost the germination seedling vigour. The agents often include plant growth regulators, micro-fertilizers, pesticides, insecticides. present investigation was carried out to assess...

background: cadmium (cd) is a heavy metal that is widely utilized in industries and contaminates soil and groundwater. there are several environmental problems related to cadmium, therefore, the technical and economic methods of removing cd are of great importance. so this study was conducted to evaluate the efficiency of a type of plant to remove the cd from aqueous environments. methods: in t...

The potential of extracts prepared from seeds of three citrus species (orange, lemon and grapefruit) to stabilize lipid oxidation of cooked and raw broiler meat under refrigeration storage was evaluated and compared with butylated hydroxyl anisole (BHA), a synthetic antioxidant. The citrus seed extracts were separately applied at a rate of 1.5% of the weight of the meat. There was a negative co...

In a study of the action of bacteria in soil it is frequently desirable to determine the relation that exists between the microorganisms and higher plants. The procedure is comparatively simple if small plants or seedlings are used. For this purpose test-tubes, especially the large Pyrex tribes described by Knudson, 1 give excellent results. Where it is necessary to grow large plants and to car...
