They are, in my opinion, the most outstanding figures ( among the youngest ones ), and the following must be borne in mind about them: Bukharin is not only a most valuable and major theorist of the Party ; he is also rightly considered the favourite of the whole Party, but his theoretical views can be classified as fully Marxist only with great reserve, for there is something scholastic about him ( he has never made a study of the dialectics, and, I think, never fully understood it )...

It involves two major research tasks, namely: ( i ) the construction of instruments and procedures for measurement ; and ( ii ) the development and refinement of theoretical approaches to measurement.

One of the major tasks of rheology is to empirically establish the relationships between deformations and stresses, respectively their derivatives by adequate measurements, although a number of theoretical developments ( such as assuring frame invariants ) are also required before using the empirical data.

His major theoretical and cultural statement from this period is The Art of Being Ruled ( 1926 ).

There have been two major branches in the field of language learning ; the empirical and theoretical, and these have almost completely separate histories, with each gaining ground over the other at one point in time or another.

In medicine, the major problem of the emergence of resistant bacteria is due to misuse and overuse of antibiotics.

The authors noted an apparent superior efficacy of olanzapine to the other drugs in terms of reduction in psychopathology and rate of hospitalizations, but olanzapine was associated with relatively severe metabolic effects such as a major weight gain problem ( averaging over 18 months ) and increases in glucose, cholesterol, and triglycerides.

Further, 43 percent of respondents said they use less than half the functionality of their existing system ; 72 percent indicated they would trade functionality for ease of use ; 51 percent cited data synchronization as a major issue ; and 67 percent said that finding time to evaluate systems was a major problem.
