The Journal of Chemical Ecology has been publishing an increasing number of contributions that report experiments that use the methods of molecular biology. In 2004, a special issue of the Journal [JCE 30(12)] focused on molecular chemical ecology and documented the increasing trend of published submissions with molecular content (Seybold 2004). The guidelines presented here were developed to p...

Background: Edible films and coatings have potential benefits for food packaging, particularly meat products. These coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. In this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was...

Background: Chemistry laboratories of universities are dangerous. However, there is no appropriate instrument to assess staffs' awareness. The present study aims at developing a standardized instrument for awareness assessment of laboratory personnel on safe work. Methods: The present study is a kind of developing instrument methodology. The study was implemented in two phases: (I) generating ...

Organic fertilizers play a significant role in organic systems and sustainable soil management. In general, organic fertilizers increase soil fertilization so can reduce the negative effects of the excessive use of chemical fertilizers and synthetic man-made fertilizers. This study was carried out in the Medicinal Plants Farm of Shahid Bakeri Higher Education Center of Miandoab during summer 20...

In this paper, we propose a re-ranking algorithm using post-retrieval clustering for content-based image retrieval (CBIR). In conventional CBIR systems, it is often observed that images visually dissimilar to a query image are ranked high in retrieval results. To remedy this problem, we utilize the similarity relationship of the retrieved results via post-retrieval clustering. In the first step...

Coal is a major source of energy. The available Indian coal quality is very poor having very high ash content and low calorific value. Indian coal generates a large quantity of ash as a by-product of combustion. The objectives of the present study were to reduce the ash content of coal to produce ultra-clean coal. The coal was treated wi...
