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...
Research examining disparity between baccalaureate completion among "native" and community college transfer students has gained attention in recent years. Current and prior research has identified important pre-college and demographic characteristics with a positive relationship to baccalaureate completion. Yet few studies have focused on the influence of nonacademic and academic environmental...
This study was designed to learn the effect a specific herbicide practice on plant communities. Data were obtained from brushfields that had been aerially sprayed with 2,4-D (2,4 dichiorophenoxyacetic acid) and/or 2,4,5-T (2,4,5 trichlorophenoxyacetic acid). Qualitative data on species composition, cover percent, height, response to herbicide and site description were...
The purpose of the study was to identify a list of skills, knowledges and related factors that are common to fourteen occupational cluster areas representative of the work community of Oregon. PROCEDURES A list of skills, knowledges and related factors needed for successful employment was derived from existing task analyses...
In process control systems where an entire process
is being controlled by a computer, the component tasks of
the system have to be monitored. An efficient message
oriented environment could be an important factor in the
optimization of such systems. In this paper we discuss
the design of a real...
The minimal kernel for a network data base management
system is developed. It includes format specification for
the object schema and the data base file, and routines for
performing the basic network functions.
The object schema defines the relationship between the
schema, records, sets, and fields. It informs the system...
This study traces British government policies with regard to Palestine from the time the British Expeditionary Forces under General Allenby invested Jerusalem in December 1917 to the imposition of the Mandate with Britain as the Mandatory power, which came into effect on July 22, 1922.

Animation has long been a staple of children's television programming As
public service announcements (PSA5) have become an important part of children's
television programming, cartoon characters have started to appear in this form of
nonprogram material. By standard definition, PSAs are usually a 15 to 60-second spot
that promote education...
An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The
Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride
with aluminum chloride was shown to give one bicyclic chlorine
containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...
There are typically two responses to the complex environmental problems of our time: 1) doom and gloom and 2) optimism. There is a lot of doom and gloom in the environmental literature. This literature warns that the future portends danger for humans and their life support systems. But when one...
