Recommendations development cause selection

The Sugars Task Force s Select Committee on Nutrition and Human Needs recommended a daily consumption of sugars at 10% of total calories, which approximates current (11%) daily intake levels in the United States. At this level, sucrose does contribute to the development of dental caries however, no firm evidence exists that it causes dietary imbalances or deficiencies of vitamins (qv), minerals, or trace nutrients (62). 

Prazosin, terazosin, doxazosin, tamsulosin, and alfuzosin have been studied extensively and used widely in patients with benign prostatic hyperplasia. With the exception of tamsulosin, the comparative efficacies of each of these drugs, especially in comparison with relative adverse effects such as postural hypotension, appear similar, although direct comparisons are limited. Tamsulosin at the recommended dose of 0.4 mg daily is less likely to cause orthostatic hypotension than the other drugs. There is growing evidence that the predominant a,-receptor subtype expressed in the human prostate is the a,-receptor. Developments in this area will provide the basis for the selection of Ct receptor antagonists with specificity for the relevant subtype of aj-receptor. However, the possibility remains that some of the symptoms of BPH are due to aj-receptors in other sites, such as bladder, spinal cord, or brain. 

The major sources of dilute, metal ion liquors are identified within the metals production/processing and chemical industries. Problems associated with traditional methods of metal ion removal are highlighted and the developing role of electrochemical techniques is discussed. Electrode and cell reactions are illustrated via typical examples from laboratory and industrial practice. The need to select an appropriate cell design and to control the reaction conditions is emphasised via consideration of the problems caused by secondary reactions. Important design criteria for electrochemical reactors are summarised. Available reactors are classified according to the nature of the product which may be metal flake or powder, a metal deposited onto a disposable substrate, a metal ion concentrate or an insoluble metal compound. The applications for electrochemical techniques in environmental treatment are illustrated by examples which show features of reactor construction and their typical performance. Current trends are summarised and recommendations are made for further work in critical areas. 

Differences between the statistical methods used in the various packages caused that not all the packages gave identical confidence ranges for the estimated parameters. The values obtained varied by more than a factor 2. In order to allow the user to interpret and use the statistical output properly, the software developers are recommended to add more explanation concerning their statistical methods, and/or to add additional methods from which the user can select.
