This publication is one of the first attempts to describe Oregon's seafood industry in economic terms. It draws together information from many local, state, and federal sources. When data were not available, they were developed from basic sources.
Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...
The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase
(EC 2.1.1.41) activity by endogenous cellular components has
been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺,
NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition
by potassium cation has been studied, and we have found that energy...
A transaminase (aminotransferase, EC 2. 6. 1) was extracted and
purified approximately 148-fold from shoot tips of pea (Pisum sativum
L. cv. Alaska) seedlings and some properties of the enzyme were
determined. The purification included acetone precipitation followed
by column chromatography on hydroxylapatite.
With a-ketoglutarate as co-substrate, the acetone precipitated...
Purpose of the Study:
The purpose of the study was to determine the characteristics
of existing secondary school advisory committees and the effects
that these groups have on local vocational programs which they
serve. The major purpose of this study was to ascertain, through
statistical analyses, the degree to which...
Much effort can be saved by having well-documented field notebooks and field sheets. ITABLE will produce notebook pages filling in the collector's name, dates, stations, and depths.
Stability, substrate and inhibitor specificity and electrophoretic
properties of a crude polyphenol oxidase (PPO) preparation extracted
from d'Anjou pears (Pyrus communis L.) were investigated. Levels
of polyvinylpyrrolidone and pH of buffer for extraction were found
to affect the specific activity of the extracted enzyme. An extract
prepared with 1.5 g...
The material in this paper is divided into the following four chapters for convenience. Chapter 1 explains, how the idea of fault testing changed from testing the machine instructions to testing the hardware in logic circuits. Chapters 2, 3 and 4 present the different approaches considered, namely:
1. Path sensitizing...
The purpose of this study was to evaluate the professional
preparation of teachers of health in selected Oregon high schools.
The accomplishment of this problem was dependent upon (1)
determining the standards or content areas for professional education
of all high school health teachers and (2) determining the
present professional...
