Problem-induced

A deflected shaft is absolutely straight when rotated in a lathe or dynamic balancer. The deflection is the result of a problem induced either by operation or. system design. The deflected shaft also will fail prematurely in the pump, leaving similar, but different evidence on the elo.se tolerance rubbing parts in the pump. The next two pictures show how a bent shaft appears when rotated 180 degrees (Figure 9-9 and Figure 9-10). 

On the negative side, the MCFC suffers from sealing and cathode corrosion problems induced by its high-temperature molten electrolyte. Thermal cycling is also limited because once the electrolyte solidifies it is prone to develop cracks during reheat-... 

Lipolysis has been classified as spontaneous or induced. This distinction is made because different measures have to be taken to correct the problem. Induced lipolysis is most frequently defined as lipolysis initiated in raw milk by some form of mechanical agitation. Traditionally, spontaneous lipolysis has been defined as lipolysis caused by the cooling of raw milk. The cooling requirement is no longer strictly adhered to, and lipolysis in raw milk is said to be spontaneous if rancidity develops without apparent mechanical agitation (Downey 1980A,B). The distinction between spontaneous and induced lipolysis is not always clear, and both may occur at the same time. 

Dopamine agonists are useful for treating problems induced by hyperprolactinemia amenorrhea, galactorrhea, breast tenderness (mastodynia), infertility, and hypogonadism. 

At the Haight Ashbury Free Clinics, it has been noted that some of the clients self-medicated their hallucinogenic-precipitated psychotic episodes with amphetamines. ° Often, this self-medication with amphetamines resulted in the development of amphetamine abuse, followed by secondary heroin, barbiturate, or alcohol abuse patterns, to ameliorate the side effects of the amphetamines. Thus, in certain patients, chronic psychological problems induced by LSD and other hallucinogenic drugs led to complicated patterns of polydrug abuse that required additional treatment approaches. ...

While continuous use of LnfOTOs is possible, it is also easy to recover Ln(OTf)3 compounds themselves. Lanthanide triflates are more soluble in water than in organic solvents such as dichloromethane. Almost 100% of Ln(OTl)3 was quite easily recovered from the aqueous layer after the reaction was completed and could be reused. The reactions are usually quenched with water and the products are extracted with an organic solvent (for example, dichloromethane). The lanthanide triflate is in the aqueous layer and removal of the water is all that is required to give the catalyst which can be used in the next reaction (Scheme 14-1). It is noteworthy that lanthanide triflates are expected to solve some severe environmental problems induced by Lewis acid-promoted reactions in industry chemistry [20]. 

It is often the case with multiple regression analysis involving large numbers of independent variables that there exists extensive colinearity or correlation between these variables. Colinearity adds redundancy to the regression model since more variables may be included in the model than is necessary for adequate predictive performance. Of the methods available to the analytical chemist for regression analysis with protection against the problems induced by...

Ln(OTf)3 are expected to solve some severe environmental problems induced by Lewis-acid-promoted reactions in industrial chemistry (Haggin 1994). 

The use of tobacco containing various carbohydrate additives, such as the various sugars listed in Table Vlll-1, has been the subject of much discussion recently in attempts to link such additives to medical problems induced by cigarette smoke. The major concern was the generation of carbonyl compounds such as formaldehyde and acetaldehyde. 

In principle, the approach of a TA study can be applied to all areas. If differentiation is according to purpose, which means according to the problem, the technology, or the project, the result is a TA typology which makes a distinction between problem-induced, technology-induced, and... 

Problem-induced TA studies are directed toward acute or foreseeable problems in society, for example, the CO2 enrichment of the atmosphere or ozone layer destruction in the stratosphere by fluorine-chlorine hydrocarbons and the resulting consequences. Here the research leads to consideration of so-called macroalternatives, which lead away from the original problem-solution. 

The studies thus classified are not unrelated. However, the problem-induced TA study is a contradiction of the basic idea of technology-consequence evaluation, at least when it deals with acute problems which the analysis should have prevented. However, one should not foi et that a development could proceed in a way which was not foreseen or was considered improbable. It would then be appropriate to return to the TA studies at suitable intervals to check earlier decisions in the context of new... 

Immrmolabelling of organelles or structures by fluorescent antibodies in living cells has the advantage, compared to work in fixed cells, that the dynamics of the labelled structures or molecules can be studied by for example time-lapse microscopy. Also, labelling in living cells does not suffer from possible problems induced by the fixation or permeabilization of the cells as is necessary for immimofluorescence or electron microscopy. 

The neutral, five-membered heterocyclic ring compounds, pyrrole and fiiran, also show aromatic character. Even thiophene is considered aromatic (Fig. 13.49). Furan and pyrrole can complete an aromatic sextet of n electrons by using a pair of nonbonding electrons in a 2p orbital. These molecules have the same number of n electrons as the cyclopentadienyl anion, but none of the problems induced by...
