Paleomagnetism and secular variation of Easter Island basalts

Creator:: Isaacson, Laurie Brown
Abstract:: The paleomagnetic history of the volcanic rocks of Easter Island was investigated using standard paleomagnetic techniques. The remanent magnetization of 673 specimens from the three volcanic episodes recognized on the island were measured using a spinner magnetometer. Inclinations, declinations and virtual geomagnetic poles were calculated for each flow. The majority...

A statistical analysis of extreme chinooks in Montana as they relate to large scale circulation changes

Creator:: Grant, Roland Lester
Abstract:: A statistical analysis of extreme chinooks in Montana as they relate to large scale atmospheric circulation changes is the subject of this thesis. A mean chinook situation was identified which indicated that a critical pattern of the surface flow always contained a Polar or Arctic airmass which overspread the prairie...

Differential sensitivity of two common groundsel biotypes (Senecio vulgaris L.) to several s-triazine herbicides

Creator:: Radosevich, Steven R.
Abstract:: Studies were initiated to determine the response of two common groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides. Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine (simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)- s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys- triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine (prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio- s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6- methylthio-s-triazine (prometryne). One biotype was much more susceptible than the...

Sphaeromyxa maiyai sp. n. (Protozoa:Myxosporidea) : a light microscopic and ultrastructural analysis employing the scanning and transmission electron microscopes

Creator:: Morrison, N. Donald
Abstract:: Sphaeromyxa maiyai sp. n. (Myxosporidea:Myxiidae) is described from the gall bladder of the Pacific tomcod, Microgadus proximus Girard, from Newport, Oregon. The plasmodial (=trophic, trophozoite) stage is discoid averaging between 1 and 2 cm. The spore averages 27.6 x 5. 6μm with pyriform polar capsules averaging 9. 3 x 3....

The effect of hexachlorophene and related compounds on torula yeast glucose-6-phosphate dehydrogenase and some other dehydrogenase enzymes

Creator:: Wang, Jun-Lan
Abstract:: Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6...

A fast division algorithm

Creator:: Dum, Stephen Anthony
Abstract:: A radix 2n non-restoring division algorithm is described. The algorithm is designed to be compatible with hardware multiprecision multiplication methods currectly used in high speed digital computers. This enables the use of the same hardware, with only changes in control logic, to be used to implement both multiplication and division....

Morphological variations in populations of Lacerta from islands in the Adriatic Sea

Creator:: Clover, Robert C.
Abstract:: Phenetic relationships in insular populations of Lacerta sicula and L. melisellensis correspond to geologic ages of the islands in two regions of the Adriatic Sea. Populations of L. melisellensis on older islands are more similar to populations of L. sicula than are L. melisellensis from younger islands, and examination of...
