Boron has been recognized since 1923 as an essential
micronutrient for vascular plants, but its function is
still not known. Many diverse roles have been proposed,
but none of these has been definitively shown. Problems
that have made the study of the function of boron
difficult include, no useful radioisotope,...
This study was designed to evaluate the relative effectiveness
of a new college general biology course which utilized an audio -
tutorial laboratory as contrasted with a traditional lecture course.
Five biology classes with 720 students at the Kansas State
Teachers College in Emporia, Kansas, participated in the study.
The...
BACKGROUND: Cranberries (Vaccinium macrocarpon Ait.) contain high levels of phytochemicals such as proanthocyanidins (PACs). These polymeric condensations of flavan-3-ol monomers are associated with health benefits. Our objective was to evaluate phytochemicals in fruit from Hawaiian cranberry relatives, V. reticulatum Sm. and V. calycinum Sm. Normal-phase HPLC coupled with fluorescence and...
The nature of the isoprenoid pathway and diversity of biologically
significant products suggests that the pathway may be highly regulated,
particularly under stress conditions, where the availability of high
energy intermediates is limited. It was postulated that germinating
seeds suffer from a limited supply of available energy and must therefore...
International students are a growing population at many institutions of higher education in the United States, and they face unique challenges in navigating both higher education and the United States as a whole. Though there is significant research about international students, few studies have examined how international students perceive student...
The objectives of this research were to investigate the optimal conditions for anthocyanins extraction from different anthocyanin rich fruit and to develop microencapsulation formulation for improving stability of anthocyanin extracts. In the extraction optimization study, two extraction methods, "conventional solvent extraction (CE)" and "ultrasound-assisted extraction (UE)" for three different anthocyanin-rich...
The objective of this research is to shed light on the phenomenon of independent volunteer traveling. It represents a form of tourism in which travelers independently organize their own volunteer efforts and typically provide assistance to local people in return for room and board. Travelers operate outside the confines of...
Fresh ripe, cantaloupes were processed into juice and
juice concentrate. Processing trials were conducted on
fresh and frozen fruits with and without rind. The effects
of maceration enzymes and fining agents on yield and quality
were investigated. Compositional measurement included
°Brix, pH, titratable acidity, formol values, ascorbic acid
content, total...
Purpose of the Study The primary focus of this study was to compare Iowa Tests of Educational Development (ITED) subtest scores with achievement letter grades (A, B, C, D, and F) in vocational education classes at Bartlett High School, Anchorage, Alaska. The two secondary purposes of the study were to...
Grapevine red blotch virus (GRBV) is a single-stranded DNA virus that causes grapevine red blotch disease (GRBD). Symptoms of GRBD include red discoloring of leaf margins and red veins on the underside of the leaves. GRBD affects the plant's metabolism and photosynthetic pathways, and disrupts carbon translocation and chlorophyll concentrations....
