The Effects Of Proper Machine On The Noise Emissions Produced By Power Tool And Machine Operations In The Industrial Woodworking Laboratory, Dwight C. Collins
The Effects Of Proper Machine On The Noise Emissions Produced By Power Tool And Machine Operations In The Industrial Woodworking Laboratory, Dwight C. Collins
Theses and Dissertations
The purpose of this study was to determine the maximum reduction of A-weighted noise produced by operations of woodworking power tools and machines on various materials by stringent implementation of proper machine maintenance practices within the woodworking laboratory.
Literature was surveyed to determine the depth and scope of the problem of hearing loss resulting from exposure to excessive noise produced by woodworking power tools and machines. An overview of studies in the areas of physiological and psychological effects of noise on humans and the control of machine noise were included.
The data were gathered and analyzed from operations of machines …
A Study To Determine The Needs For Offering Courses In Building Trades In The Grand Forks School District, Anthony G. Eckroth
A Study To Determine The Needs For Offering Courses In Building Trades In The Grand Forks School District, Anthony G. Eckroth
Theses and Dissertations
This study was undertaken for the purpose of determining the needs for offering a building trades course in the Grand Forks senior high schools, Grand Forks, North Dakota. The following information was ascertained to determine the feasibility for such a program: (1) the employment opportunities in the building trades field--both locally and nationally, (2) the student interest in such courses, (3) the support given by local building trades firms for such a program (4) the building trades skills that should be stressed, (5) the sources p:r;esently used by local building trades employers for obtaining skilled laborers, and (6) to state …

A Taxonomic Investigation Of The Algae Of The Brigham Young University Campus, Provo, Utah, Cheng Mou-Sheng
A Taxonomic Investigation Of The Algae Of The Brigham Young University Campus, Provo, Utah, Cheng Mou-Sheng
Theses and Dissertations
A taxonomic investigation of the algal flora of the Brigham Young University campus was conducted from October 1971 to August 1972. This algal flora consisted of 27 genera and 36 species of Chlorophyta, 2 genera and 2 species of Euglenophyta, 32 genera and 106 species of Bacillariophyceae (including 16 genera and 33 species of soil diatoms), 1 genus and 2 species of Chrysophyta excluding diatoms and 6 genera and 14 species of Cyanophyta. Diatoms were the predominent algae in this study. Chlorococcum humicola, Vaucheria geminata, Amphora normani, Hantzschia amphioxys and Oscillatoria sancta were prominent in the greenhouses. In the arboretum …
Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence
Transforming Ability Of Bacillus Subtilis Dna Taken Up By Barley Embryos, Christine Tolman Ence
Theses and Dissertations
Purified Bacillus subtilis DNA taken up by one-day-old barley embryos and permanently fixed within the barley cell is shown to have maintained its biological activity in B. subtilis transformation. Cesuim chloride density gradient centrifugation of DNA isolated from the roots of barley embryos after the uptake and incorporation of radioactive, bromouracil-labelled B. subtilis DNA indicates the presence of the bacterial DNA in several discreet bands of well-defined density, whose density is changed by sonication. These preliminary findings concerning the fate of bacterial DNA taken up by barley roots are discussed in terms of the recombination model of Ledoux and Huart …
The Determination Of Thiamin And Its Derivatives In Brain Tissue Of Control, Thiamin-Deficient, Oxythiamin- And Pyrithiamin-Treated Rats, David S. Murdock
The Determination Of Thiamin And Its Derivatives In Brain Tissue Of Control, Thiamin-Deficient, Oxythiamin- And Pyrithiamin-Treated Rats, David S. Murdock
Theses and Dissertations
The determination of total thiamin, free thiamin, thiamin di phosphate (TDP) plus thiamin triphosphate (TTP), and total α- hydroxyethylthiamin (HET) levels in rat brain in control, deficient, oxythiamin- (OTH) and pyrithiamin- (PTH) treated rats was accomplished. It was found that the TDP + TTP/thiamin ratio observed in the thiamin-deficient, OTH- and PTH-treated rats was constant and did not differ from the ratio observed in the control rat brains. The brain levels of TDP + TTP decreased to 39% and 12% of the control thiamin levels in deficient and PTH-treated rats respectively. The brain HET and TDP + TTP levels of …

The Effect Of Aflatoxin B1 On Growth Rate And Iron Metabolism In Juvenile Mongolian Gerbils (Meriones Unguiculatus), William Stanley Hastings Jr.
The Effect Of Aflatoxin B1 On Growth Rate And Iron Metabolism In Juvenile Mongolian Gerbils (Meriones Unguiculatus), William Stanley Hastings Jr.
Theses and Dissertations
The metabolic secretions from Aspergillus flavus, aflatoxins. are often found as contaminants of agricultural products used for human and animal consumption. Aflatoxin B1 is the most toxic and carcinogenic of the aflatoxins. A reduction in weight gain has been observed when juvenile animals are fed aflatoxin B1 over an extended period of time. This reduction in weight gain may possibly result from an anemic condition induced by an alteration of iron absorption and/or distribution. The effect of chronic sublethal levels of this hepatocarcinogen on weight gain and the uptake and distribution of 59Fe++ were studied in this investigation.
