Vegetation ecology of Fraxinus latifolia communities in William L. Finley National Wildlife Refuge, Oregon

Creator:: Heinitz, Eric Fajen
Abstract:: Composition and structure of Oregon ash (Fraxinus latifolia) woodlands in the William L. Finley National Wildlife Refuge, Oregon are described. Twenty stands dominated by Fraxinus latifolia were sampled with 500 m2 circular macroplots in which floristic microplot data were collected for plant community synthesis. Plant communities were identified by computer-assisted...

Siloxy-cope rearrangements of the trans-l-vinylcyclotridec-3-en-l-ol system

Creator:: Bolesta, Richard Edward
Abstract:: The thermolysis of trans-1 -trimethylsiloxy- 1-vinylcyclotridec- 3-ene (VI-OTMS) led to the formation of two major products: 4-vinylcyclotridecanone (VII) and cyclopentadec-5-en-l-one (VIII) after hydrolysis. Ketone VII is produced by a concerted [3, 3] sigmatropic shift, while ketone VIII is formed by a [1, 3] sigmatropic shift with a concerted or diradical...

The effect of temperature on biochemical activities of embryo and seedling of germinating rice (Oryza Sativa L.) seed

Creator:: Luo, Shun
Abstract:: Some biochemical activities in embryo or seedling of germinating rice (Oryza Sativa L.) seed were studied to explain the effects of suboptimum (20 C), optimum (30 C), and supraoptimum (40 C) temperatures on seed germination and seedling growth. It was observed that 40 C slightly speeded up seed germination but...

Polyphenol oxidase of D'Anjou pears (Pyrus communis L.)

Creator:: Halim, David Husien
Abstract:: 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 effects of L-ascorbic acid, thiamine HCl, or L-cysteine on ethanol and acetaldehyde blood levels and disposition

Creator:: Acholonu, Wilfred W.
Abstract:: The effects of L-ascorbic acid, thiamine HC1, or L-cysteine on acetaldehyde blood levels and disposition were investigated in acetaldehyde- treated rats. Rats were treated with ascorbic acid (2 mmoles/kg), thiamine (0.24 mmole/kg), or cysteine (2 mmoles/kg) one hour before the administration of acetaldehyde (6 mmoles/kg). The results show that each...
