Research comparative

Such results suggest a need for further research comparing trained with untrained subjects, along with an examination of muscle fiber type ratios of experimental subjects. Also, the question of subjects habituation to caffeine needs to be explored more fully. For the present, the reported ergogenic effects of caffeine on muscular strength must be viewed with skepticism and perhaps be attributed to the psychostimulant properties of caffeine. [Pg.249]

The State of New Jersey has been able to correlate airborne radiation measurements to clusters of buildings with elevated indoor radon 49 In this study, researchers compared airborne y-ray spectrometer data with indoor radon data to see if any trends emerged. For the conditions in New Jersey,... [Pg.1293]

Because of the gradual loss of neutron irradiation facilities (and the general public unpopularity of nuclear sciences), NAA is being slowly replaced by other techniques, chiefly ICP-OES, and more recently ICP MS, which has comparable sensitivity. It has, consequently, become necessary to carry out research comparing these techniques since there is a need to know how compatible ICP data are with the vast databanks (such as the Aegean databank discussed above) of NAA. This has included comparison of NAA with ICP OES on bone (Akesson et al. 1994) XRF and NAA on ceramics (Garcia-Heras et al. 2001) NAA, XRF, ICP-OES, and ICP MS on ceramics... [Pg.134]

To further extend the utility of structural methods, researchers compare solid state X-ray crystallographic and solution-state NMR structures to define important differences. For instance, the Bertini group has studied the enzyme matrix metalloproteinase 12 (MMP12), in the presence of its inhibitors. Matrix metalloproteinases (MMPs) are involved in extracellular matrix degradation, a fundamental step in tissue remodeling and repair. There are a great variety of enzymes of this type, the one studied here is one of many found in humans. Most MMPs have three domains (1) a prodomain that is removed... [Pg.119]

In 1994, Rayox developers generated cost estimates for the technology based on bench-scale studies. Using a proposed cleanup site in Canada as a model, researchers compared these estimates with the costs of using an air stripper/liquid carbon/catalytic oxidizer (air/carbon) option. Results indicated that UV/peroxide treatment, with or without an iron catalyst, was found to have an estimated capital cost equal to the air/carbon option at the site (D12302U). [Pg.431]

Available online. URL http //www.plosone.org/article/info%3Adoi%2Fl 0.1371%2 FJournal.pone.0000982. Accessed May 28,2009. The researchers compared some of the 518 known human protein kinases, and introduced an algorithm that may become useful in predicting their structures. [Pg.33]

Perre, David, Andre Langaney, Mario Chech, Maria Teschler-Nicola, Maja Paimovic, Phihppe Mennecier, et al. No Evidence of Neandertal mtDNA Contribuhon to Early Modem Humans. PLoS Biology. March 2004. Available onhne. URL http //www.plosbiology.org/article/info doi/10.1371/joumal.pbio.0020057. Accessed May 28, 2009. The researchers compared mitochondrial DNA found in four Neanderthal fossils from Germany, Russia, and Croatia to that of modern humans. They found that the Neanderthal mtDNA sequences were similar to one another but were not found in mtDNA of modern humans. [Pg.195]

In analyzing the subjective data, the researchers compared the responses by the officials of the different companies in the sample to detect consistencies and/or differences. This comparison was made to differentiate between responses that were unique and those that appeared representative of the sample as a whole. The attitudes, philosophies, and predictions of the upper-level R D officials interviewed in this study will, in large part, determine the future R D policies and plans of these companies and, therefore, are highly significant in accessing the impact of environmental protection regulation and its future ramifications. [Pg.75]

Although there is ample evidence to suggest that both long and brief naps can be effective in improving or even restoring daytime alertness and performance, there has been only limited research comparing brief naps with naps of longer duration. [Pg.461]

Several standard-sized alternative egg-laying breeds are available worldwide. In the USA this includes Rhode Island Reds, New Hampshires, Barred and White Plymouth Rock, and Buff Orpingtons. There appears to be a lack of published peer-reviewed research comparing the productivity of these breeds in an organic production system. Many organic egg producers in the USA keep a flock for multiple years and run multiple ages together. The choice of a different coloured breed each year makes it possible to keep track of the age of each of the hens in these flocks. [Pg.255]

Research comparing the psychological effects of human-caused versus natural disaster has yielded equivocal results. No one type of disaster is worse than another, although the number of associated deaths and serious injuries can be expected to have the most significant and longest lasting impact on physical and emotional well-being. [Pg.84]

The unique structure of Ceo and access to an effective method for the production of macroscopic quantities opened up a new era of carbon research compared with what was known up to that date [150,151]. The field of fullerenes is a truly interdisciplinary area which has been covered in a number of proceedings, review articles and books [152-164]. As examples of some recent... [Pg.31]

The Lyon Diet Heart Study gave us the first solid proof of the benefits of the Mediterranean diet in reducing heart disease. French researchers compared that diet, rich in olive oil, nuts, olives, avocados, and seafood, with the kind of diet typically prescribed by cardiologists in the United States, the United Kingdom, Australia, and elsewhere, which cut way back on fat, while replacing the fat calories with carbohydrates. The subjects were patients who had suffered heart attacks within the past six months. [Pg.170]

Endocrine disruption is a newly discovered mode of action and has encouraged a great deal of research. Compared to some of the other mechanisms described in this chapter, endocrine disruption is more subtle with alterations in reproductive physiology and morphology often being the effects, instead of death. Because of the hormone-like activity, these compounds can have identifiable effects at very low concentrations. It is not yet clear what the overall importance of endocrine disruptors are in creating environmental impacts compared to other modes of action. [Pg.154]
