Borate Rods As An On-Site Remedial Treatment For Control Of Decay In Wood Decks, Mark G. Dietz, Elmer L. Schmidt
Borate Rods As An On-Site Remedial Treatment For Control Of Decay In Wood Decks, Mark G. Dietz, Elmer L. Schmidt
Journal of the Minnesota Academy of Science
A conventional wood recreational deck constructed with spruce-pine-fir lumber was sampled for active growth of wood decay fungi before and 10 months after remedial preservation treatment with fused disodium octaborate rods (IMPEL®) at boric acid levels from 1.5-10 kg/m3. Extent of boron distribution was observed with a color indicator dye (curcumin) after 10 months exposure. Remedial treatment with the boron rods. was nearly 100% effective. Active decay cultures from treated material were found only in samples obtained from boards treated at the inhibition dosage level (1.5kg/m3) of boric acid. Suggested lethal dosages (>3kg/m3) were effective in all cases as …

Here Is Where We Are, M. H. Baker
Journal of the Minnesota Academy of Science
Industrial chemistry in the Upper Midwest consists principally of compounding, formulating and specialty manufacturing rather than the production of basic chemicals. The economic position of industrial chemistry is, nevertheless, significant because many of the region's major corporations are employers of technically-trained personnel and are substantial chemical users. This paper provides a non-quantitative overview of chemical technology applications and developments in some of the area's key industries as a record of the past, a measure of current activity, and as a possible indicator for the future. The paper also notes that the large investment demands, complexity of regulations and distance from …
A Pycnometer Of Improved Design, Richard Moore
A Pycnometer Of Improved Design, Richard Moore
Journal of the Minnesota Academy of Science
The density of a solution must be known to laboratory medicine , biochemistry, and physical chemistry. Knowledge of the density may permit calculation of solution concentration, solute molecular weight, solute partial, or specific volume , for example. Therefore, the determination of the density of a solution is a measurement which must be made with precision, accuracy, and sensitivity. This report describes a pycnometer which permits making such measurements.
An Investigation Of Amino Acid Decomposition, Jack H. Frost, E. Winston Grundmeier
An Investigation Of Amino Acid Decomposition, Jack H. Frost, E. Winston Grundmeier
Journal of the Minnesota Academy of Science
Amino acid decarboxylation studies generally show that extraneous reactions accompany CO, formation, especially at high temperature and when metal ion catalysts are used. In the present study some of these reactions are investigated in the reaction system, a- or ,a-amino acid and CuSO, at 130-155° C. Histidine, a- and .B -alanine, glycerine and norvaline were each studied for determination of products. The extent of formation of the products, NH,, CO,, aliphatic amines and Cu metal, was determined quantitatively. A near l: l correspondence in NH,:CO2 exists for the amino acids studied. No correspondence could be detected between Cu metal product …
