Distorted message

The message from both pentalene and benzene/cyclohexatriene examples is of the persistence of the mobility of tt electrons under constraints imposed by a a framework. This resilience and 7r-distortivity are opposite sides of the same coin. 

Finally, Dr. E and Dr. T were a united front, frequently reassuring Mr. F with a more hopeful reality than the one he frequently described. Furthermore, when his distortions convinced him that they were hiding information, such as a positive test result, they provided consistent information because of their frequent communication and shared charting and could vouch for each other s noble intentions. Mr. F was appreciative of their communication about him, which delivered a message that he was an important patient and that the doctors were working as a team devoted to giving him the best possible care. 

The journalist Edith Efron published The Apocalyptics Cancer and the Big Lie (Simon and Schuster, New York, 1984) to expose how politically-motivated scientists distort evidence and create unjustifiable alarms about carcinogens in the environment. The tone of Efron s book is one of anger and its message conspiratorial. Although it is highly repetitive, it is packed with information and expresses a view held by many scientists.

The data that is collected is a-buzz with noise and subject to systematic distortion. To understand the message hidden within, one must separate it from the surrounding noise and confusion. 

These hazards are probably more serious in the study of saccharide assembly than in the synthesis of polypeptide. The absolute requirement for a message in the form of a linear polynucleotide, to specify the particular amino acyl transfers that can occur, largely prevents the possibility of inappropriate synthesis of polypeptide, and powerful techniques exist for identifying and characterising the labelled products of such synthesis. While the true rates of various steps in this process may be distorted in a cell-free system, the sequence of events and the mechanisms of each step are demonstrably almost unaltered and are accessible to detailed analysis. With oligo- and poly-saccharides there can be difficulties and these must be clearly appreciated in evaluating much of the work to be described below and in the chapters that follow. 

It is thus not possible to obtain a phase-sensitive 45 projection of a normal homonuclear 2D J spectrum, and instead it is usual to project the absolute value or the power spectrum. This gives rise to distorted intensities and peak positions, but nevertheless is an extremely useful aid to assignment. The subject of phase-sensitive proton spectra without multiplet splittings is not however entirely closed, despite the clear message of the projection-cross-section theorem, and will be returned to later. In the interim, some of the many data acquisition and handling methods discussed above will be illustrated with some experimental spectra. 

As for the mechanism by which the formation of the repressive complex brings about repression, the picture is still blurred. Presumably, the repression process involves degradation of message or interference with translation or both. Since there is evidence for message degradation as a quantitatively important phenomenon, it seems reasonable to infer that the repressive complex facilitates the action of a nuclease. The complex may thus distort, or otherwise affect, the ribosome and expose the message to attack by a nuclease. 

In this case, after the constant A is blocked with a capacitor, the demodulated output consists of the message signal multipHed by the interference, cos lit Aft and an additive component of the interference, Ac cos InAft. The effect of interference is much worse in this case because the multipHcative interference results in serious distortion. 

Many problems in health and safety arise due to poor communication. It is not just a problem between management and workforce - it is often a problem the other way or indeed at the same level within an organization. It arises from ambiguities or, even, accidental distortion of a message.
