Environmental concern has been an important issue for a few decades and the extent of consumer demand for eco-friendly consumption has increased. The article presents research results concerning the willingness to pay (WTP) for selected green products, defined by the auction method. Moreover, the paper presents the interrelations between the perceived benefits, individual value system and the W...

This work proposes OCLAS (Organic Chemistry Language Ambiguity Solver), an automatic system to analyze syntactically and semantically Organic Chemistry compound names and to generate the pictures of their chemical structures. If both parses detect that the input name corresponds to a theoretically possible organic chemical compound, the system generates its molecular structure picture, whether ...

A novel, simple and environmentally friendly method is reported for the preparation of 1,8-dioxo-octahydroxanthene derivatives by the reaction of dimedon with various aromatic aldehydes, using thiamine chloride  as a recyclable catalyst under solvent-free conditions. This procedure has following benefits; simple workup, moderate reaction times, good yields, and completely compatible with enviro...

The major purpose of this study was to examine the advantages and implications of biogastechnology in the agriculture sector. Biogas is one of many biomass energy sources, which includeanything that was once alive and that can generate energy (except for fossil fuels, which are notrenewable). To talk of biogas is to talk of agriculture, since biogas generation starts withagricultural waste prod...

The organic food market is considerably expanding all over the world, and the related dairy market represents its third most important sector. The reason lies in the fact that consumers tend to associate organic dairy products with positive perceptions: organic milk is ecoand animal-friendly, is not produced with antibiotics or hormones, and according to general opinion, provides additional nut...
