Disinfection of Fertile Eggs of Free-Range Poultry with Essential Oils

Chemical residues in poultry and eggs produced in free- range or organic systems

Residues in poultry arise from accidental or intended exposure to chemicals. The exposure routes are by oral ingestion (feed, water, soil and preening), by inhalation, by dermal absorption or by injection. Chemical contaminants are not a major issue in the principles of organic or free-range systems. Risk management of chemicals has not been addressed widely and if so the attention was focused ...

determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

The greenhouse emissions footprint of free-range eggs.

Eggs are an increasingly significant source of protein for human consumption, and the global poultry industry is the single fastest-growing livestock sector. In the context of international concern for food security and feeding an increasingly affluent human population, the contribution to global greenhouse-gas (GHG) emissions from animal protein production is of critical interest. We calculate...

Antioxidant and free radical scavenging activities of essential oils.

INTRODUCTION Reactive oxygen and nitrogen free radicals are produced during immune activity, and are triggered by several environmental factors such as pollution, smoke, and sunlight. Harmful effects of these reactive species include cellular damage to RNA, DNA, proteins and lipids. In humans several diseases including those connected with the heart, lung, and the eye are associated with the ac...
