Danish example

All in all, new sorting technologies in combination with large-scale slaughtering lower the degree of asset specificity between pork producers and processors. In the Danish example, farmers and their local abattoir are heavily dependent on each other by the use of special genetic. Toennies reaches a similar output without contracts on a spot-market basis or, at best, long-term relationships with their suppliers. 

The Danish List of Undesirable Substances is a list of chemicals of concern that the government believes should be avoided to the extent feasible in commerce. Using a systematic analysis, substances are selected automatically if they meet some clear and defined criteria, for example, problematic classifications, because they are imder suspicion for being PBT/vPvB (Persistent, Bioaccumulative, Toxic/very Persistent, very Bio accumulative) or endocrine-disrupting. 

New figures from GfK, a Danish market research agency, show that total market share for organic meat, fruit and vegetables, in the first 6 months of 2003 was 5.6%. Doorstep schemes are attracting interest. Some examples of the activities organised ... 

This is the basic problem with any attempt to evaluate the overall effectiveness of placebos, as Beecher and the Danish researchers had tried to do. There is not just one placebo effect. Instead, the placebo effect depends on a host of factors. It depends, for example, on the condition being treated, the way in which the placebo is administered, the colour of the placebo, its price, whether it has a recognized brand name and the dose that is prescribed. Studies of the placebo effect reveal that, all else being equal, taking placebo pills four times per day is more effective than taking them only twice a day brand-name placebos are more effective than placebos presented as generic drugs placebo injections are more effective than placebo pills and more expensive placebos are better than cheaper ones.16... 

Beginning in the 1700s and beyond, scientists suspected that an unknown metal existed in alum. Alum is found in the form of several compounds—for example, aluminum ammonium sulfate [A1NH IS0 )j 12H20], aluminum potassium sulfate [AlK(SO )2 12HjO], or aluminum sulfate [Alj(SO ) j]. The scientists problem was that they had no techniques or knowledge of how to extract the metal from its ore until 1825 when the Danish chemist Hans Christian Oersted (1777-1851) isolated a very small amount of aluminum by melting alum with potas-... 

One example for this volume effect is the hesitant substitution of the plasticiser DEHP in soft PVC products". In this respect the attempt of the Danish environmental authorities to compensate for the competitive disadvantage of substitutes by taxing phthalates is also notable.

With the particlelike nature of energy and the wavelike nature of matter now established, let s return to the problem of atomic structure. Several models of atomic structure were proposed in the late nineteenth and early twentieth centuries. A model proposed in 1914 by the Danish physicist Niels Bohr (1885-1962), for example, described the hydrogen atom as a nucleus with an electron circling around it, much as a planet orbits the sun. Furthermore, said Bohr, only certain specific orbits corresponding to certain specific energy levels for the electron are available. The Bohr model was extremely important historically because of its conclusion that electrons have only specific energy levels available to them, but the model fails for atoms with more than one electron. 

As indicated in Table 7.10, only in the last decade have models considered all three phenomena of heat transfer, fluid flow, and hydrate dissociation kinetics. The rightmost column in Table 7.10 indicates whether the model has an exact solution (analytical) or an approximate (numerical) solution. Analytic models can be used to show the mechanisms for dissociation. For example, a thorough analytical study (Hong and Pooladi-Danish, 2005) suggested that (1) convective heat transfer was not important, (2) in order for kinetics to be important, the kinetic rate constant would have to be reduced by more than 2-3 orders of magnitude, and (3) fluid flow will almost never control hydrate dissociation rates. Instead conductive heat flow controls hydrate dissociation. 

Astronomy and chemistry are usually considered very different sciences, with very different historical paths. Whereas astronomy is observational and based on the exact laws of celestial dynamics, chemistry is the archetypical experimental science. Yet speculations about interconnections between the two fields can be found far back in time. To mention but one example, in his 1807 lectures on the history of chemistry, Hans Christian 0rsted prophesied that some day chemistry will have just as much influence on astronomy as mechanics so far. He added that Then it will be necessary to regard external motion as a product of internal forces, and all natural science will finally become a cosmogony. [4] 0rsted s prophecy eventually became reality, but the path followed from chemistry to astronomy took a different direction than imagined by the Danish scientist. To become useful in the science of the heavens, chemistry first had to prove its worth in the study of the earth.
