The Use Of Saline-Soluble Tissue-Proteins In Systematic Serology, William B. Stallcup

Field and Laboratory

In recent years the emphasis of taxonomic studies in many animal groups has been at or near the species level, with often little done to clarify the relationships of the higher taxonomic units. This was either because it was felt that these units needed no revision, or that there was not enough new information at hand to warrant any revision. In many cases, groups of genera have been placed in a family simply because of some superficial resemblance.

Bulletin No. 374 - Fertilizer Reuirements Of Alfalfa Hay In Utah, R. F. Nielson, J. P. Thorne, G. T. Baird

UAES Bulletins

This bulletin is a report of one phase of research in agronomy. What is agronomy? Agronomy is the science of crop production and soil management and includes a scientific study of all phases of soils and soil conservation, irrigation practices, fertilizer usage, crop rotations, plant breeding, selection and management of new crop varieties, weed control, and other practices that lead to increased production of better quality crops.

Optimization Of A Kraft Pulp Dioxirane Bleaching Stage, Eric A. Thompson

Paper Engineering Senior Theses

This research characterized and optimized the bleaching potential of dimethyldioxirane (DMD) on an -oxygen-delignified hardwood kraft pulp. The DMD wash produced in-situ using a caroate (2KHSO₅^.KHSO₄^.K₂ SO₄) acetone under controlled conditions. The studied variables included chemical concentration, consistency, temperature, reaction time, and chelation. Statistically designed experiments with response surface, methodology were used - to help locate the optimum conditions with respect to pulp brightness and strength. These conditions were located at 2.8% AO (activated-oxygen charge), 5.5% consistency, and 55^° C.

It was found that over 95% of the total brightness …

Bulletin No. 1, The Dallas Seismological Observatory, January 1-March 31, 1954, Edward L. Hazelwood, Louis V. Hull, Harriss Laramore

Field and Laboratory

Since this station is comparatively new and the personnel relatively untrained, the following system was used in preparing these data. The USCGS H times and deltas, measured on a large, inaccurate globe, were used in conjunction with Gutenberg time-charts to identify each phase. The identifications were made by Edward L. Hazelwood and are as accurate as this method will permit.

Notes On Texas Compositae – X, Lloyd H. Shinners

Field and Laboratory

LIATRIS MUCRONATA DC. f. Tharpii Shinners, f. nov. Corollis albis. TYPE : abundant on limestone prairie about five miles north of Austin at Walnut Creek, B. C. Tharp & Barton H. Warnock 45-35, Oct. 3, 1945. Color forms ordinarily are scarcely worth the trouble of giving Latin names. This one is a striking variant of an endemic which is also commonly cultivated, and has itself been introduced into cultivation. It seems desirable to assign a name to a plant with excellent horticultural possibilities, and appropriate to name it in honor of the man who brought it into cultivation.

Bee Visitors Of Penstemon Ellipticus (Scrophuhlariaeceae) On Eddy Peak, Sanders County, Mont., In Summer Of 1954, Robert Kral

Field and Laboratory

Eddy Peak, in the Cabinet National Forest of northwest Montana, is part of a large fault system in which thousands of feet of shale were thrust up to form an escarpment overlooking the Clark Fork River. The summit elevation is 7500 feet. Fracturing of the uppermost layers of shale has resulted in many talus slopes, some of them hundreds of yards from top to bottom, on the dip side of the strata. Parts of the mountain crest consist of nothing but a jumble of shale blocks in a very unstable state. During the summer of 1954 several slides occurred. Apparently …
