abstract: oxidation might be regarded as one of the most important reaction in oils and fats. prooxidants namely iron and copper intensify and catalyze the oxidation while the chelating agents might retard or delay this process. citric acid, phosphoric acid, some of phenolic compounds and phospholipids are considered as the compounds that chelate the prooxidant metals and through this mechanism...

Fluorescent retroviral envelope (Env) proteins were developed for direct visualization of viral particles. By fusing the enhanced green fluorescent protein (eGFP) to the N terminus of the amphotropic 4070A envelope protein, extracellular presentation of eGFP was achieved. Viruses incorporated the modified Env protein and efficiently infected cells. We used the GFP-tagged viruses for staining re...

Green marketing is a process of producing environment friendly product. Such type of products that are safe from different hazards. Now a days Green marketing is exploring day by day. The eco-friendly products are making by many companies in Globe. Our Purpose of this study is basically to identify that what kind of factors influence the green purchase intentions of consumer of Pakistan. Four p...

Silver nanostructures as an effective antibacterial materials were synthesized via three various hydrothermal, sono-chemical and microwave methods using water as a green solvent. Then Chitosan-Ag polymer based nanocomposites were made by a fast chemical procedure. The influence of power, temperature and time on the morphology and particle size of the products was investigated. Scanning electron...

The development of green food production, establishment and management of collecting and sorting documentary materials has been put on the agenda. Vigorously strengthen the production bases of green food, the producers of green food, wholesale markets of green food, distribution entities of green food, sales units of green food and supervision and management, establishing the certificate record...

since 1980, green marketing movement has been widely regarded by organizations consumers. organizations- seeking social legitimacy produce environment friendly products, while try to influence environmental issues. hence, this paper tries to know sensitivity level of consumers to environment issues, rate of participation in social programs related to green marketing and the level of attention a...

in this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. in this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were reduced to their corresponding reduce...

na2so4 as an inexpensive and effective catalyst has provided a green protocol for the synthesis of tetrahydrobenzo[b]pyran, pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2c]chromene derivatives from the three-component domino reaction of aromatic aldehydes and malononitrile with 4-hydroxycoumarin/ dimedone/ barbituric acid in ethanol/water as a mixture of solvent that, this mixture entirely is ...

Consumers' awareness on products marketed in green marketing is important in guiding their purchasing decision of green products. This study aims to examine the influence of consumers' environmental concerns, awareness of green product, price and brand image on their purchasing decision of green products. A total of 200 completed responses were collected in the survey. Responses were randomly d...

silica gel has been used for synthesis of biscoumarin derivatives starting from 4-hydroxycoumarin and aryl aldehydes. the reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. this method is also simple and inexpensive and leads to high yield of products in short reaction times.
