The power of minds at work organizational intelligence in action

Unearths how the neatest (and dumbest) enterprises functionality, and the way executives and executives could make their very own departments and firms paintings extra intelligently. offers a pragmatic framework for outlining, assessing, and constructing the collective intelligence of any firm.

Stellar Movements and Structure of Universe

This publication an actual replica of the unique booklet released sooner than 1923. this isn't an OCR'd booklet with unusual characters, brought typographical error, and jumbled phrases. This ebook could have occasional imperfections similar to lacking or blurred pages, bad photos, errant marks, and so on. that have been both a part of the unique artifact, or have been brought by means of the scanning strategy.

Creating Value with Science and Technology

Do technological know-how and expertise create price for society and the economic climate, and the way may perhaps one pass approximately measuring it? How can we overview its advantages? will we also be sure that there are advantages? Geisler argues that there are merits, and they outweigh in price the damaging affects that necessarily accompany them.

The State of Copper in Ceruloplasmin. The early room temperature magnetic susceptibility studies of Ehrenberg et al. (58) showed t h a t only about 40~/o of the Cu bound to ceruloplasmin was paramagnetic. Aisen et al. (IS5) have carefully measured the paramagnetic contribution to the magnetic susceptibility of ceruloplasmin over the temperature range 2 - 4 . 2 °K. In this temperature range Curie's law is followed precisely, and the total susceptibility is exactly proportional up to a measuring field strength of 18 kgauss.

It is evident that for the more slowly reacting substrates Vmax/Km-kl obtained from transient studies. The authors point out that the apparent lack of correspondence with the faster reacting substrates is probably due to difficulties in the direct measurement of kl. As might be expected, there is an excellent correlation between kl (obsd) and Km-1, supporting the relatively simple assumptions regarding the rate limiting processes. This correlation may be explained in terms of an enzymatic reaction which does not involve formation of the classical E .

These experiments suggest that NO. may coordinate directly to Type 1 Cu since NO +, necessarily formed upon reduction of the Cu ~+, is known to be a very reactive nitrating agent, and the reversibility or the above reaction suggests that it is probably not released into solution. However, the possibility that the two Type 1 Cu ~'+ are reduced by NO. via an intramolecular route cannot be excluded. If all the assumptions which have been made in the interpretation of the above described perturbation experiments are correct, all Types of Cu are accessible to perturbants; this seems very unlikely.
