Soil is the sink and source of heavy metals (both geogenic and anthropogenic) and plants are the ecosystem regulators, balancing the chemistry of life on earth. However, roots are the only connection between soil and plants, which are the real engineers of ecosystem dynamics responsible for environmental balance and stability. The plant-soil interface termed as ‘rhizosphere’ is a typical zone o...

Modern intensive livestock and poultry production has achieved phenomenal gains in the efficient and economical production of high quality and safe animal products and by-products. Furthermore, the overall performance of livestock can be increased by improving nutrients utilization, health status, fertility and efficiency of production. The use of feed additives has been an important part of ac...

The wall of the gut responds to an impressive array of signals originating in the lumen, including nutrient and non-nutrient chemicals, mechanical factors, and micro-organisms. The idea that the gut wall exhibits luminal chemo-sensitivity is implied in the original discovery of secretin by Bayliss and Starling, and has become an integral part of models of neurohumoral control of gastrointestina...

Surface translocation by the soil bacterium Myxococcus xanthus is a complex multicellular phenomenon that entails two motility systems. However, the mechanisms by which the activities of individual cells are coordinated to manifest this collective behaviour are currently unclear. Here we have developed a novel assay that enables detailed microscopic examination of M. xanthus motility at the int...

This paper reports on the state-of-the-art of technologies for the design and fabrication of MEMS micro-mirrors. We discuss the major design issues, considerations, calculations and restrictions of micro mirrors. The materials employed for the reflective surfaces are described along with their properties. The materials used for the static and dynamic MEMS micro structures as well as the differe...

The fishing industry is deeply dependent on complex and high quality diets consisting of dry feed, vitamins and micro/macro-elements. The suitable dose of each essential nutrient is different based on the fish species, their age and physiological conditions. In this study, the effects of two recommended doses of riboflavin (20 and 30 mg vitamin per each kg dry feed) on growth, hematological and...
