Co-operative unit

DPPC isotherms in the LE-LC coexistence region Albrecht et al. l estimated a size of the order of 10 moleeules per co-operative unit. 

The role of Zn in the folding of bovine CA-B has been investigated by various physicochemical techniques. The metal appears to stabilize part of the molecule and enable the whole protein to act as a more co-operative unit but the authors feel that its presence is not vital for the enzyme to fold in the correct manner. 

The scanner has been constructed in modules which, for future applications, makes it easy to increase the length of the scanner for inspection of larger blades, by adding further modules to the system. In co-operation with LM Glasfiber and RIS0 it was decided to construct the first scatmer for inspection of blades with a length of max. 21m. In order to be able to scan primarily the bonded areas from the root to the tip of the rotor blade, a so-called X-unit module was constructed. The movement from the root to the tip of the blade was controlled by the P-scan system. 

At the beginning of 1992, the largest Hquids pipelines in the United States, based on pipeline length, were Amoco Pipeline Co., 19,096 km Mobil Pipe Line Co., 15,026 km Exxon Pipeline Co., 14,983 km and Conoco Pipe Line Co., 12,980 km. Distances do not include 1316 km of the Trans-Alaska Pipeline with multiple ownership. In both 1991 and 1992, the product pipeline company with the most product deHveries was Colonial Pipeline with 104,990,000 m, more than double the amount deHvered by Santa Ee Pacific Pipelines, Inc. The top pipeline in terms of cmde oil deHveries was the Alyeska Pipeline Service Co., operator of the Trans-Alaska Pipeline System, with movement of 105,735,000 m (3). 

Oxamide is produced commercially by Ube Industries, Ltd. (Japan) and a pilot process is being operated by Enichem (Italy). It is not produced domestically as a commercial fertilizer, although it was the subject of much research and development activity by the Tennessee Valley Authority s (TVA) National Fertilizer Research and Development Center. It is made in small quantities for industrial use by AUied Chemical, Hummel Chemical Co., and United Guardian, Inc. Oxamide has appHcation as a controlled release nitrogen source for the turf and specialty agricultural markets.

Corrosion represents the joint effort of over 100 authors, all of whom have been free, within the necessary limitations of length, to express their own views. Grateful acknowledgements are made to the individual authors from Great Britain, the United States, and Canada for their valuable and enthusiastic co-operation. 

In many ways, both Canada and the United States continue to be involved in a unique experiment of co-operative management of serious environmental issues which plague a shared international resource. Despite the institutional complexity and the history of abuse that man s activities have wrought on the Great Lakes, the experiment to restore and protect them has had several successes typhoid and cholera were eradicated eutrophication problems are now largely under control and where adequate control programs for toxic chemicals have been implemented and enforced (e.g., mercury, DDT, PCBs), there have been associated declines in concentrations in the lakes. These successes have been due in no small way to the spirit of co-operation that has continued to exist between Canada and the United States and the unique institutional arrangements entered into by the two countries.

Robert Williams In the course of reductionism, what you try to do and it s perfectly fair to use the gradient in this sense, is you try to study a phenomenon and relate it to some property. Now, how far you can go with that depends on the level you re trying to reach. In this case, it s perfectly fair to say that a certain observation is a function of an observable gradient. In the same way it s perfectly fair to say in thermodynamics, although we don t understand the nature of liquids really, we understand it has something to do with the co-operative nature of the whole system. And I cannot relate it to the property of a single molecule. And this is the trouble - this is where you get the co-operative impact on a particular measurable. That is then, if it s the co-operatively that does it. In fact, it s not strictly reducible all the way to individual units, but you may reduce it to a certain level. And in... 

The recognised body in the United Kingdom for the preparation of specifications for quality, performance or dimensions, methods of test, definitions and symbols, codes of practice, etc. British Standards are prepared under the guidance of representative committees and are widely circulated before they are authorised for publication. BSI co-operates in preparing international standards for rubber and plastics through ISO/TC45 and ISO/TC61 respectively. See ISO. 

Dr. von Knieriem s essays on the waste in European commerce were as brilliant as his thoughts on the need for social co-operation in the distribution of goods. Even after the United States got into the war, many who were cursing the Nazi aggressions appreciated Von Knieriem. Within a few weeks, after all the testimony against him was in, he would be visited by American patent experts who would tell him that the essays were still being reprinted in the United States.

The AMFC Directive requires that food-control laboratories should be accredited to the EN 45000 series of standards as supplemented by some of the OECD GLP principles. In the UK, government departments will nominate the United Kingdom Accreditation Service (UKAS) to carry out the accreditation of official food-control laboratories for all the aspects prescribed in the Directive. However, as the accreditation agency will also be required to comply to EN 45003 Standard and to cany out assessments in accordance with the EN 45002 Standard, any other accreditation agencies that are members of the European Co-operation for Accreditation of Laboratories (EA) may also be nominated to cany out the accreditation. Similar procedures will be followed in the other Member States, all having or developing equivalent organisations to UKAS.
