This book is intended to serve as a reference text for advanced scientists and research
engineers to solve a variety of fluid flow problems using computational fluid dynamics
(CFD). Each chapter arises from a collection of research papers and discussions contributed
by the practiced experts in the field of fluid mechanics. This material has encompassed a
wide range of CFD applications concerning computational scheme, turbulence modeling
and its simulation, multiphase flow modeling, unsteady-flow computation, and industrial
applications of CFD....
Fall is rodent time. This means it’s also time to step up your
rodent monitoring and control efforts. Food resources in the
fields and woods are beginning to get scarce for rats and mice
this time of the year, forcing them to move into poultry houses
where food and water are plentiful. Be ready by tightening up
your poultry houses and having plenty of rodenticide on hand.
Start with a walk around the poultry houses. Be alert for signs
of new rodent activity (gnawing, bits of fallen insulation,
droppings, tail marks and tracks). Note the...
In this Agrodok, we mainly refer to the extensive and semi-intensive
farming. Intensive farming with e.g. battery cages will not be treated.
When chickens are free to roam and scavenge, we talk about exten-
sive, free-range chicken farms. The level of capital and labour invest-
ment is low. Housing is not important.
Intensive systems, developed for specialised breeds, are estimated to
be in use for about 30% of the poultry population in Africa. These are
mainly found in and around urban areas with good markets for eggs
and chicken meat.
