Mixed-solvent solutions of various cosolvent-water proportions are titrated and psKa (the apparent pKa) is measured in each mixture. The aqueous pKa is deduced by extrapolation of the psKa values to zero cosolvent. This technique was first used by Mizutani in 1925 [181-183]. Many examples may be cited of pKa estimated by extrapolation in mixtures of methanol [119,161,162,191,192,196,200], ethanol [184,188-190,193], propanol [209], DMSO [212,215], dimethylformamide [222], acetone [221], and dioxane [216]. Plots of psKa versus weight percent organic solvent, Rw = 0 — 60 wt%, at times show either a hockey-stick or a bow shape [119]. For Rw > 60 wt%, S-shaped curves are sometimes observed. (Generally, psKa values from titrations with Rw > 60 wt% are not suitable for extrapolation to zero cosolvent because KC1 and other ion pairing interferes significantly in the reduced dielectric medium [223].)... 

Surface-water samples are usually collected manually in precleaned polyethylene bottles (from a rubber or plastic boat) from the sea, lakes, and rivers. Sample collection is performed in the front of the bow of boats, against the wind. In the sea, or in larger inland lakes, sufficient distance (about 500 m) in an appropriate wind direction has to be kept between the boat and the research vessel to avoid contamination. The collection of surface water samples from the vessel itself is impossible, considering the heavy metal contamination plume surrounding each ship. Surface water samples are usually taken at 0.3-1 m depth, in order to be representive and to avoid interference by the air/water interfacial layer in which organics and consequently bound heavy metals accumulate. Usually, sample volumes between 0.5 and 21 are collected. Substantially larger volumes could not be handled in a sufficiently contamination-free manner in subsequent sample pretreatment steps.

The sixth theme, catbocycks from carbohydrates, explores bow functionalized cy-lopentanes and cyclohexanes can be prepared from carbohydrate precursors, thereby attending the usefulness of sugars for the synthesis of mainstream organic compounds. 

A work of this kind, which obviously summarizes accomplishments, may engender in some the feeling that there is litde more to achieve. Quite the opposite is the case. In looking back and seeing bow far we have come, it becomes only more obvious how very much more we have yet to achieve. The vasmess of the problems and opportunities ensures that research in organic synthesis will be vibrant for a very long time to come. 

Alkylosing spondylitis is an inflammatory autoimmune reactive arthritis with a primary end organ target of the intervertebral joints and the sacroiliac joint at the hip. The characteristic features are a bowed spine and inflamed joints. Compared with 8% of Caucasians as a whole, 95% of people with alkylosing spondylitis have the HI. A B27 allele. Unlike many autoimmune diseases, alkylosing spondylitis is more common in men and has an early onset between 20 and 40 m years of age. 

Tuberculosis (TB) may be caused by one of three mycobacterial organisms MTB, Mycobacterium bows, or M. africanum. The vast majority of MTB cases throughout the world are due to M. tuberculosis. 

The great crossroads that was the plan s point of departure has been variously interpreted as a symbol of Christ s cross or an Amazonian bow. Costa, however, referred to it as a monumental axis, the same term that Le Corbusier used to describe the center of many of his urban plans. Even if the axis represented a small attempt to assimilate Brasilia in some way to its national tradition, it remained a city that could have been anywhere, that provided no clue to its own history, unless that history was the modernist doctrine of ciam. It was a state-imposed city invented to project a new Brazil to Brazilians and to the world at large. And it was a state-imposed city in at least one other sense inasmuch as it was created to be a city for civil servants, many aspects of life that might otherwise have been left to the private sphere were minutely organized, from domestic and residential matters to health services, education, child care, recreation, commercial outlets, and so forth. 

These two reactions—nucleophilic substitution and base-induced elimina tion—are two of the most widely occurring and versatile reactions in organ chemistry. We ll take a close look at both in this chapter to see how the occur, what their characteristics are, and bow they can be used to synthesize new molecules. 

Also there is Taxol, derived from the bark of the Pacific yew, an evergreen tree or shrub, notably of the Pacific Northwest. (Yew wood was once favored by the Indians for bows and other purposes.) If successful, its relative scarcity vs. demand indicates that chemistry will have to come to the rescue, especially the specialty known as organic synthesis.
