The Debate Continues

In any event, confident applications [118] of the QCT paradigm, with titles such as Where to draw the line in defining a Molecular Structure continue to appear. At the 2003 fall meeting of the American Chemical Society Lichtenberger presented a paper on the bonding in the adduct resulting from the reaction of HSiCU with Cp(CO)2Mn, complaining that valence bond

Dennis was moved to the river house, and Vanessa and Ev became his nurses. I preferred to continue to live at the jungle house to avoid crowding. The debate continued as to whether the direction in his raving was toward improvement or whether he was only drifting further into the world in which he had become lost. As residents of Berkeley, we had all encountered acid casualties comparison of Dennis s state with those lost souls was not reassuring. Dennis s move to the river was a turning point, for from then hence the effects the phenomenon unleashed were less in our minds and more in the world. 

FDA) withdrew its approval for their use. Congressional hearings with manufacturers in 2005 produced new information that has reversed the FDA s ban on their use— but only with certain manufacturers of implants. The debate continues. 

In September 2001, however, a news item in the British Medical Journal reported that further analyses confirmed the increase in rates of myocardial infarction and questioned whether this was an adverse reaction affecting the whole class of COX 2 drugs. The debate continued for the next 3 years with the main emphasis remaining on GI toxicity. A PEM study that included more than 15 000 patients made no mention of cardiovascular adverse events. However, a second paper compared rofecoxib and meloxicam with respect to thromboembolic events which showed that both, to a variable extent were associated with cardiovascular, cerebrovascular and peripheral venous pathology. A meta-analysis published recently in The Lancet suggests that Merck, the licence holder... 

Thus it is evident from all these studies that the nature of the C—Li bond varies from compound to compound hence any generalization of the nature of bonding is to be taken cautiously. As Schleyer and Streitwieser have discussed in the past, the C—Li bond is essentially ionic however, the covalent components cannot be neglected . The unnsnal behavior of the C—Li bond has been a subject of discussion from the initial years of applying theoretical methods, and the debate continues in an interesting manner due to the developments of new theoretical methodologies. In fact, we support the implications of Bickelhaupt that there is a covalent contribution to the C—Li bonding, however small this turns out to be in specific examples . 

The Marian Diamond studies are not without controversy. For example. Dr. Lucy Rorke, a neuropathologist in Philadelphia, feels that the number of glial cells was in fact normal, but she was impressed that the brain showed none of the usual degenerative changes one sees in older people. Rorke said it looks like the brain of a young person. Terence Hines of Pace University has also pointed out that the Diamond work may have statistical flaws in its analysis of Einstein s brain, so the debate continues.

Was this your answer The uncertainty is due to the large number of variables that determine global weather. As the debates continue, bear in mind that the issue is not global warming itself but rather its potential effects. 

A theoretical understanding of furan and its congeners followed in the wake of the progress with the benzene problem, but for the five-membered heterocyclic compounds Bamberger s centric formula was always the most reasonable one, as Kekule structures could not be written at all. It is not now clear to what extent the heterocycles were really regarded as benzene analogues, but a remark made by Hantzsch, that coumarone is the furfurane of the naphthalene series was certainly percipient. Furan is variously said to be aromatic, superaromatic or not aromatic at all, for the debate continues. 

There is another side to this process. Many doctors now believe that unsaturated fats are healthier than saturated ones. Because of this, many margarines are left partially unsaturated. They do not have all the C=C taken out of the fat molecules. However, the matter is far from settled and the debate continues.

Enough has been said of the origin of life to show that the problem is as far from solution as it was in Charles Darwin s time. The debate continues (Line, 2002). The geologist can make little contribution to this debate, except to point out possible habitats where the hrst life could have been bom. 

Most significantly, these studies showed that the debate as to whether the oxidising species was the hole or the surface-bound OH radical was pointless since these two are but one indistinguishable species. Yet the debate continues to this day, with many researchers continuing to distinguish between the two entities. 

Another leading radiochemist, Kasimir Fajans, objected to the interpretation of these results on the basis of a thermodynamic analysis and put forward the view that isotopes are different, not just physically but also chemically (Fajans, 1914). Various other experiments were then devised and carried out in an attempt to settle the issue, but the debate continued and, indeed, was widened to the question of what constitutes a chemical element. 

Other surface techniques that have been applied to this system (e.g. XANES, XPS, and high-resolution transmission electron microscopy) also provided further support for the overall picture. As for the precise geometry of the active sites, the debate continues. 

The debate continues as to which hydantoin (i.e., phenytoin or fosphenytoin) is the preferred agent in GCSE. Although phenytoin has been used for decades, it is associated with a variety of problems related to its formulation. Conversely, fosphenytoin is associated with less infusion pain and intavenous-site complications and fewer hemodynamic adverse effects than phenytoin. While most practitioners believe that fosphenytoin is clearly a "better" formulation, many practitioners and administrators struggle with the benefit of fosphenytoin when compared with phenytoin given its cost. 

As far as we are aware there are no examples of the location of an H atom, by neutron diffraction, within a tetrahedral cavity, and so the debate continues. 

The existing ambiguity in the interpretation of sustainability into practical use may have been an enabling factor in its broad adoption in the many varied contexts and applications in which it can be found. Although the debate continues, most authors recognize that sustainability involves...

The basic function of vitamin C is the prevention of scurvy. The current recommended dietary allowance of the Food and Nutrition Board of the United States National Academy of Sciences-National Research Council, 45 mg/ day for an adult, is adequate to prevent scurvy in essentially all normal persons. The question of whether or not a larger intake could lead to better health and a greater control of disease was raised almost as soon as the pure compound became freely available, and the debate continues.
