-
(1977)The involvement of neurotransmitters in the inhibitory effect of suckling on plasma LH was investigated. The effect of suckling on the plasma LH levels was studied when the activity of the neurotransmitters, dopamine or ...
-
(1977)Micronizing is accomplished by heating the grain with infra-red burners and crushing the heated kernels between corrugated steel rollers. This study examined for the first time the chemical, physical, and structural changes ...
-
(1977)Ferroelectric crystals show an unexpected T³ᐟ² term in the specific heat. An experiment is discussed, as well as background information on ferroelectrics and specific heats, in which the thermal expansion coefficient is ...
-
(1977)The question whether Prehistoric Tikal was agriculturally self-sufficient based on slash and burn agriculture is proposed. The problem is evaluated from the standpoint of its four most fundamental components: (1) Peten ...
-
(1977)The effect of random mixing of marked and unmarked fish on the accuracy of a Petersen population size estmate was investigated. By comparing the ratio of marked and unmarked fish in a sample catch at different points in ...
-
The Effect of Plant Sterols on the Growth, Survival, and Sterol Levels in Macrobrachium Rosenbergii (1977)Growth in Macrobrachium rosenbergii was studied using diets in which plant sterol was substituted for cholesterol. Weight changes, mortality, molt cycle, and sterol levels were observed. Results of a study of the effect ...
-
(1977)In preparing to assist a developing nation, both the foreign student and the foreign bound American student have special educational needs. A format is proposed with which such students can guide their own studies and plan ...
-
(1977)A metabolism trial was conducted using eight crossbred Brahman steers to determine the effect of grain processing on protein solubility and digestibility of sorghum. Sorghum grain evaluated was a commercial hybrid grown ...
-
(1977)Rats were trained to asymptotic running speed in a straight runway and were then given pretraining with either escapable shock, inescapable shock, or no shock. Subjects were then tested in the runway in the presence of ...
-
(1977)The performance of a flat plate solar water heater is predicted by a computer model. This model divides the collector and storage tanks into a finite number of sections and considers an energy balance over each section. ...
-
(1977)Lysyl oxidase from bovine ligamentum nuchae has been purified by two different methods. The first method utilized urea extraction, ion exchange chromatography, and affinity chromatography. The second method consisted of ...
-
(1977)Changes in the ratio of compressional to shear seismic wave velocities prior to an earthquake occurrence. Two models have been suggested to explain the mechanism by which the compressional wave velocity is allowed to vary ...
-
(1977)The second order pseudopotential theory is applied to the calculation of stacking fault energies for the noble metals and their alloy systems with tin and zinc. The theory fails to simulate the known experimental values ...
-
(1977)Cesium selectivity (kg) exponentially increased as Cs saturation decreased in the <0.2μm clay fraction and possibly in the 2-0.2μm clay and 20-2μm silt fractions of the lignite associated shale. The <0.2μm clay fraction ...
-
(1977)Complementary infrared and x-ray photoelectron spectra have been interpreted in a detailed study of surface equilibria involving SO₂, NO₂, N₂O₄, and H₂O adsorbed on amophous silica and silica alumina. Heterogeneous oxidation ...
-
(1977)A key point in the regulation of pyrimidine biosynthesis by prokaryotic organisms is the enzyme Aspartate Transcarbamylase. This enzyme catalyzes the reaction of carbamyl phosphate plus aspartate to yield carbamyl aspartate, ...
-
(1977)Transfer RNA (tRNA) methyltransferases were partially purified from Manduca sexta prepupa larvae and 2-day-old pupae. The purification procedure involved pH 5 precipitation, gel filtration to remove endogenous inhibitors ...
-
(1977)Computers have become an integral part of accounting practice but have been ignored in the area of accounting education. This study proposes to determine the feeling of the accounting profession in both the public and ...
-
(1977)A recent development of the NASA Airfoil Research Program is a family of new high lift, low drag airfoils for application on general aviation aircraft. This study analyzes one of these airfoils, the 13% thick GA(W)-2, as ...
-
(1977)The temporal development of Dictyostelium discoideum is altered by the disruption of pyrimidine metabolism in amoeba during mitotic cell division or following nutritional starvation. The well-defined differentiation process ...
