Photosynthetic carbon metabolism in Hydrilla verticillata Royle
(1981)
520-00Photosynthetic characteristics of the aquatic angiosperm Hydrilla verticillata Royle were studied under different experimental conditions. Photosynthetic rate closely paralleled the free CO2, concentration when only ...
Endocrine regulation of ovarian development, respiration, and fat body mitochondrial respiratory enzymes in adult female Blaberus discoidalis Serville
(1981)
These studies were designed to investigate effects of a corpora cardiaca (CC) extract upon oocyte maturation, respiration and synthesis of mitochondrial respiratory enzymes in females of the cockroach, Blaberus discoidalis ...
Good roads for Texas :a history of the Texas Highway Department, 1917-1947
(1981)
History has unfurled itself on the highways of Texas. From the period of the Spanish conquistadors, Texas roads have assumed an essential role in the history of the state. Road development contributed to the Christianizing ...
Precipitation field and intrastorm flow of supercell convective storms
(1981)
Single-Doppler radar data, when supplemented by surface and upper-air information, provides good estimates of the intrastorm kinematic structure of supercell storms. Spatially derived fields of radial velocity, defined as ...
The influence of family environment on achievement and self concept among gifted students
(1981)
Recent research has revealed that a substantial number of gifted children do not achieve academically at expected levels even though most gifted students do well in school and in social relations. Family and personal ...
Rumen ammonia concentration and ammonia assimilation by rumen microorganisms
(1981)
Pathways of ammonia assimilation were investigated at low and high rumen ammonia conditions by (1) measuring the specific activities (SA) of glutamate dehydrogenase (GDH), glutamine synthetase (GS) and glutamate synthase ...
Break-even investment in a wind energy conversion system for an irrigated farm on the Texas High Plains
(1981)
The purposes of this study was to quantify the benefits of using a wind energy system for irrigation. The value of wind energy was estimated on both a static basis (where the annual value of wind power was assumed to be ...
Polarization transfer in n-p scattering at 50 MeV
(1981)
The polarization transfer parameter D(,t)(180(DEGREES)) for n-p scattering has been measured at 50 MeV. The measurement was accomplished by scattering polarized neutrons produced by the(' )D(d,n)('3)He reaction from a ...
Ascorbic acid and ancillary biochemical indices of pollutional stress in the blue crab, Callinectes sapidus, and the grass shrimp, Palaemonetes pugio
(1981)
Investigation of the ascorbic acid (AsA) status of the blue crab, Callinectes sapidus, and the grass shrimp, Palaemonetes pugio, indicated that both organisms possess significant quantities of AsA and ascorbate 2-sulfate ...
Financial intermediation and the theory of the firm : an economic growth model of federal credit unions
(1981)
The purpose of this investigation is to construct and empirically test a microeconomic growth model for the individual federal credit union. Growth is defined as the single-period percentage change in federal credit union ...
