An emerging breeding blanket that fulfills performance criteria, meets the safety requirements, and is reliable enough to meet plant availability a challenging issue assumes complex studies involving numerous neutronic analyses based on Monte Carlo simulations with MCNP code. Two different concepts are now candidates be implemented as driver for DEMO fusion reactor: WCLL (Water-Cooled Lithium L...

Recent statistics indicate that in 2005 the world consumed about 0.5 ZJ (ZJ = 10 Joules) of energy. If one assumes that the future world population stabilizes at 10 billions, and the people consume a similar amount of energy per capita to that of the people in the presently developed countries, the world will need about 2 ZJ a year. A recent survey of the available future energy resources indic...

Using annual serologic surveillance data from all poultry farms in the Netherlands during 2007-2013, we quantified the risk for the introduction of low pathogenicity avian influenza virus (LPAIV) in different types of poultry production farms and putative spatial-environmental risk factors: distance from poultry farms to clay soil, waterways, and wild waterfowl areas. Outdoor-layer, turkey (mea...

Two trials were conducted each using 240 Chinese Ringneck pheasant breeder hens (Phasianus colchicus torquatus) to determine the economics of feeding various levels of Brewers Dried Grains (BDG) on egg production, fertility, hatchability, and feed consumption. Four treatment diets containing 0, 15, 30, and 45% BDG were fed to 3 replicate pens each, beginning 1 week prior to the onset of lay. Eg...

A modular DCLL blanket is selected as the reference concept in the ARIES-CS power plant study. This concept is characterized by the following features: 1. Eutectic lead lithium alloy Pb-17Li serving as breeder and coolant (“self-cooled breeding zone”); 2. Helium-cooled FW and blanket structure made of the MF82H Reduced Activation Ferritic Steel (RAFS); 3. Flow channel inserts (FCI) made of SiCc...

Introduction A number of methods have been investigated to improve the hatchability of eggs stored for more than seven days. Recently, it was reported that pre-heating of poultry eggs before storage resulted in more live chicks and a lower level of embryonic mortality compared to eggs that were not heated [2, 6, 7, 10]. However, no previously conducted research has tested pre-incubation storage...

Modern scientific knowledge and indigenous or traditionally based knowledge are often assumed to be fundamentally different and incomparable. Testing this assumption is important theoretically and for supporting scientist-farmer collaboration to improve farmers’ well-being in their own terms. We illustrate the use of scenarios based on a basic biological model to understand farmers’ theoretical...

High quality seed of wheat is the key to successful agriculture. Improvement and evaluation of agronomic traits have been the primary objective of breeders for many years under variable environments. The objective of the present research was to determine influence of genotype, environment and their interaction on yield and randman of seed as a seed quality represent and to evaluate stability th...

impacts on profitability of dairies, primarily through its impact on average milk/ cow/ day, but also due to its impact on culling and the number of calves born. Despite improved understanding of the financial impacts of poor reproductive management, reproductive efficiency has been on the decline within the dairy industry for the last 50 years. Consequently, producers have expressed renewed in...

At the time of weaning, the human being takes over the responsibility for pet nutrition. A couple of weeks later, the puppy is handed over to the new owners, which may be less experienced than the breeder. This period is also the time of intensive turn over and growth. It is therefore obvious, that feeding imbalances in quantity and quality would have major impact on skeletal health in growing ...
