History Preceding

Crosland, "The Development of Chemistry," 371. As Crosland notes, the concept of chemical "affinity" also had a history preceding Newtonian ideas of "force."... 

Most diagenetic minerals are the same in the sandstones of the Lower Freshwater Molasse and the Upper Marine Molasse, apd there is no significant difference between the paragenesis of the two units. Minor variations are detected in the diagenetic history preceding the first calcite generation. 

Collections of exotic animals have a long history preceding the zoological parks built in the United States, of course, tmd much has been written about them. 

Even if all of the elements described so far have been present within a sedimentary basin an accumulation will not necessarily be encountered. One of the crucial questions in prospect evaluation is about the timing of events. The deformation of strata into a suitable trap has to precede the maturation and migration of petroleum. The reservoir seal must have been intact throughout geologic time. If a leak occurred sometime in the past, the exploration well will only encounter small amounts of residual hydrocarbons. Conversely, a seal such as a fault may have developed early on in the field s history and prevented the migration of hydrocarbons into the structure. 

It is one of the wonders of the history of physics that a rigorous theory of the behaviour of a chaotic assembly of molecules - a gas - preceded by several decades the experimental uncovering of the structure of regular, crystalline solids. Attempts to create a kinetic theory of gases go all the way back to the Swiss mathematician, Daniel Bernouilli, in 1738, followed by John Herapath in 1820 and John James Waterston in 1845. But it fell to the great James Clerk Maxwell in the 1860s to take... 

Based on the preceding local history, the boundaries at the elastic and plastic wave fronts are characterized by bound surface charges of equal magnitude and opposite sign to the initial piezoelectric states. The polarization in the region behind the plastic wave E3, has magnitude equal to the change... 

The preceding sections have given only a sampling of the major accidents that have occurred tlu-oughout history. However, there have been numerous other incidents, which were perhaps less renowned but certainly not less tragic to the families of the victims. E.xaniples of some less renowned accidents arc ... 

Some of tlie preceding cliapters liave dealt witli tlie history and legislation of emergency and accidents tliis cliapter addresses specifically tlie fundamentals of plant fires, explosions, and certain otlier plant- and non-plant-related accidents. 

The diagnosis of PIH is often made by history and clinical presentation. It is characterized by macules and patches of varying shades of hyperpigmentation limited to the sites of inflamed skin lesions. Lesions of the preceding inflammatory process may be present at vari-... 

Miller (1989) is the question of how such an ancient organism has come to exist on a comparatively new oceanic island. Long-distance dispersal is an unlikely explanation for the present situation. Dispersal over shorter distances from island to island seems a reasonable possibility, with subsequent disappearance of many, or apparently all in the present case, of the intermediate stepping stones. Invocation of island hopping, after all, has many precedents. As Miller (1989) pointed out, obviously some vascular plant lineages have survived, some of which may have histories that reach back to the Antarctic flora. Needless to say, deep phylogenetic analyses would be helpful in addressing this question. 

With this in mind, I have presented the information in this book in a form that can be easily understood. I think that it is quite important that any student of the body of knowledge that we call "science" needs to be cognizeuit of the history and effort that has been made by those who preceded us. It was Newton who said "If I have seen further, it is because I have stood on the shoulders of giants . Thus, I have tried to give a short history of each particular segment of solid state theory and technology. 

ExxonMobil extended the Hydrofining technology to produce a 200 ppm diesel, with the Diesel Oil Deep Desulfurization technology, DODD. The reactor is packed with multiple beds of different catalysts. A preceding history of commercial experience provided data to build a model for deep HDS and pave the way to a new technology, MAK Fining. 

A 39-year-old male with aortic insufficiency and a history of no drug allergies is given an intravenous dose of antibiotic as a prophylaxis preceding the insertion of a valve prosthesis. As the antibiotic is being infused, the patient becomes flushed over most of his body. What antibiotic was given ... 

There are, however, subgroups of young adults who may not mature out of drug problems as easily as others. Those who seem to have problems maturing out usually have other problems that preceded the onset of drug use. For instance, researchers have found that young adults who have a history of Conduct Disorder or who have other psychiatric disorders (such as schizophrenia, Bipolar Disorder, depression, Anxiety Disorder, or a major personality disorder) mature out of drug problems at much lower rates than those who do not have these additional problems. 

Please note, that if the identified contributing types of latent conditions were resolved, i.e. sufficient information from the transformation process its history of deviations and no cost pressure from stockholders were present, the control element turns effective. However, this does not automatically imply that the corresponding precursor will be alleviated. It is still possible that a control element preceding the previous initial ineffective control element, is also ineffective. 

Transmission in both cases was preceded by a clinical history of chronic prostatitis in the source patient. 

In influencing the history and philosophy of science of later decades, Comte s positivist classification created the conviction that the constitution of mathematics and physics was historically prior to chemistry and conceptually more fundamental than chemistry. 4 But the positivist history we often have accepted from Comte is flawed. "Chemistry" as a discipline preceded "physics." In the next two chapters, I will deal with the claim that physics is conceptually a more fundamental science than chemistry and will analyze the characteristic aims and methods of nineteenth-century chemistry, particularly as reinforced through the hegemony of organic chemistry.
