Welfare of animals can be defined as the kind of feelings the environmental conditions bring about in the animals. These feelings depend on the needs of the animals and their degree of satisfaction. Needs of animals, and so their welfare, are partly genetically determined. Therefore, welfare can be changed by breeding. The aim of this study was to...

This paper describes a case study where a multiple cell model is used to predict airborne concentrations in enclosures and to show how the predictions can he used to devise a control strategy. The case concerns two brickworks in The Netherlands. With a quartz content of approximately 15% in the respirable dust, the respirable dust concentrations sh...

... Furthermore, one could use a finite element type multi-cell approach, such as that used by Buringh [114,115] in an industrial application, with inter-zonal rates used across discrete boundaries (blocks of cells between zones) provided the time steps are on the order of the exchange rates. It is important to recognize that there can be substantial differences of indoor concentrations depending on whether a single zone (e.g., one room) or a two-zone (e.g., two room) approach is used. ...
... 1988 Er is veel discussie geweest, vooral over de geïntroduceerde paarden en runderen, daar niet duidelijk was in hoeverre deze dieren als wild beschouwd konden worden. Dit zou betekenen dat tegemoet gekomen moet worden aan de zorgplicht als in de Gezondheid-en welzijnswet voor dieren (huidige wet Dieren) staat omschreven (Lorimer & Driessen, 2014;Keulartz et. al, 1998). ...
... The different survival rate of progeny from the two sire lines of Duroc and Pietrain showed that breeds might be different and that choice of breed can be a useful tool to increase animal welfare. Since the breeds were obtained from different breeding programs, it furthermore demonstrates that breeding can be a useful tool to increase animal welfare ( Kanis et al., 2004). ...
... The commission refers to the care model and concludes that the introduced herbivores (especially Heck cattle and Konik horses) must be considered as 'in between fully wild and domesticated/managed' and that 'both specific care (…) and nonspecific (…) cares has to take place to reflect the moral and ethical considerations for these animals' (ICMO2 2010: 46). See also: Keulartz et al. 1998a, b; Klaver et al. 2002; Vorstenbosch et al. 2001; Waelbers et al. 2004; Swart 2005 Swart , 2007 Keulartz 2009; and Gamborg et al. 2010 for reviews and discussions on the case of introduced animals in the Oostvaardersplassen. Based on the concept of domestication and dependence of animals on their environment, discussed above, we have adapted the care model by using the animal's dependence as the X axis, rather than the wild-domesticated continuum used in the first version (Swart 2005). ...
... A textbook example hereof is the "golden rice" case. Licenses for nearly 70 patents had to be cleared out before the genetically modified rice could be marketed (van den Belt 2003;Wilson 2007). ...
... The ability of a sow to produce and rear a high number of viable piglets that meet weight targets for a desired age at slaughter is the ultimate goal in pig production. Irrespective of the target slaughter weight, which differs across countries and production systems, both management and breeding programs have to be tailored and continuously optimized to achieve this goal [3,4]. Reproductive traits have been genetically improved over recent decades [5][6][7]. ...
... Within the framework of the controversial Human Genome Diversity Project, the idea of group consent was developed in order to persuade 'indigenous' peoples all over the world into cooperation (Greely, 2001). The idea has even been elaborated into a detailed Model Ethical Protocol, but this proved not enough to save the international research projectlargely because there was too much distrust and suspicion among the representatives of 'indigenous' communities about the aims of the project Wasserloos, 2005;Van den Belt, 2006). The ethical innovation of group consent has triggered a fundamental debate about its legitimacy, which largely followed the familiar dividing lines between liberalism and communitarianism (Wasserloos, 2005). ...
