Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma Jan 1949

Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

Multivariate analysis is the simultaneous comparison of three or more variables in order to determine the significance of their likenesses and differences. The technique has been in use for some thirteen years, but no simple account of the method has hitherto been available. An illustrative example from invertebrate paleontology is here used, but the method is applicable to any problem in geology involving several quantitatively known variables.


Use Of Motion Pictures In Laboratory Dynamical Studies, Carl Bailey, Jaan Jurisson, M. Eugene Rudd Jan 1949

Use Of Motion Pictures In Laboratory Dynamical Studies, Carl Bailey, Jaan Jurisson, M. Eugene Rudd

M. Eugene Rudd Publications

In student laboratory experiments in dynamics, as, for example, Newton's second law of motion or the conservation of momentum, it is, of course, highly desirable to allow motion with the least possible constraint and to observe the displacements of moving parts without using perturbing markers. This circumstance has led us to use motion pictures in the student laboratory for quantitative observation of rapid dynamic processes, a technique which is used in a well-known textbook.' The photographic method combines maximum freedom of movement with accurate observation of position as a function of time, if the camera frame speed is sufficiently high. …


Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd Jan 1949

Geological Report Of Conrow Wood Creek Area 8 Miles N.E. Of Whitehall, Montana, Kenneth M. Judd

Bachelors Theses and Reports, 1928 - 1970

Plane table and pacing methods were used in the mapping of the individual areas, but an automobile traverse was used to tie the independent areas into a composite group that would be useful for the entire zone. All land marks, section corners, roads, fence lines, drainage, and geologic features were plotted in the field and later transferred to a master map.

Nebraska Tractor Tests

EXPLANATION OF TEST REPORT: John Deere AR

TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.

This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.

Test 418: Caterpillar Model D-2, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary. All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University. Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

Separation Of The Selenium Compounds In Seleniferous Plant Protein Hydrolysates By Paper Partition Chromatography, Arnold L. Smith Jan 1949

Separation Of The Selenium Compounds In Seleniferous Plant Protein Hydrolysates By Paper Partition Chromatography, Arnold L. Smith

Electronic Theses and Dissertations

In 1943 Franke reported that the protein of "allolied" or "toxic" wheat carried the toxicant, and Franke and Painter in 1935 reported that those "toxic" proteins contained selenium which was in organic combination in the protein. There has been much speculation regarding the possibility of selenium replacing sulfur in the amino acids cysteine and methionine. The toxicity of selenium in selenium analogs of these compounds is similar to that of selenium occurring naturally in proteins seleniferous cereals, which indicated that the selenium may be present in the proteins as the analogue of these sulfur amino acids.

Geological Survey Circular 346: First Fourteen Years Of Lake Mead, Harold E. Thomas Jan 1949

Geological Survey Circular 346: First Fourteen Years Of Lake Mead, Harold E. Thomas

Publications (WR)

This circular summarizes the results of recent studies of Lake Mead and its environs. Area-capacity tables, prepared on the basis of a hydrographic survey of the lake in 1948-49, show that the capacity of the reservoir was reduced 4. 9 percent during the first 14 years after Hoover Dam was completed, but the usable capacity was reduced only 3.2 percent. Practically all of this reduction was caused by accumulation of sediment in the reservoir. Studies of inflow and outflow indicate that the reservoir has a total storage capacity about 12 percent greater than that shown by the area-capacity table, because …
