An empirical survey investigation of energy conserving behavior of Texas citizens utilizing the human ecology theoretical perspective
(1983)
The goals of this research were to demonstrate the applicability of human ecology theory for the study of energy-society relationships, to develop hypotheses from the human ecology theoretical framework about the nature ...
A combined serviceability and distress pavement performance model for estimating remaining service life of flexible pavements
(1983)
A procedure is developed to estimate the remaining service life of flexible pavements based upon predicted ride and distress conditions. These conditions are forecast using equations that involve measurable values of ...
Avian diversity in various age pine forests in East Texas
(1978)
Objectives of this study were to quantify avian density and diversity as related to changes in vegetation structure of southern pine stands over a rotation interval (ca 35 years) and to determine the value of forest ...
Field and laboratory studies of selected marine algae of south Texas
(1978)
Field studies of the seaweeds of South Texas reveal thirty-seven new area records and many state range extensions. Selected genera were isolated into culture and studied along with field collections to insure correct ...
A forecast of the negotiability of selected educational policy items and the impact of this negotiability on education in the public schools of Texas
(1977)
The purpose of this study was to forecast a future scope of bargaining for collective negotiations between teacher organizations and school boards in Texas public schools. The study also sought to identify areas of agreement ...
Ecology and herbicidal control of selected perennial range weeds of South Texas
(1977)
Three species of perennial range weeds, common goldenweed (Isocoma coronopifolia (Gray) Greene), Drummond's goldenweed (Isocoma Drummondii (T.&G.) Greene), and spiny aster (Aster spinosus Benth.) were studied relative to ...
The nature of acidity in selected acid soils
(1977)
Most of the soils in the eastern one-third of Texas are acid. To this date little work has been done to evaluate the acid status of these soils. The present effort was initiated to study total acidity and the contribution ...
In-season pecan nut loss in Texas
(1982)
The pecan, Carya illinoensis (Wang.) K. Koch, was subjected to a life table analysis in order to assess the impact of pests and pathogens in various sites and treatment regimes in Texas. Nut clusters were initially tagged ...
Taphonomic processes in modern estuarine death assemblages along the Texas coast : rate of taphonomic loss, covariance of species, and size frequency analysis
(1984)
The formation of the death assemblage from the living benthic community was studied at two estuarine sites along the South Texas coast. Three basic topics were investigated: (1) Rates of taphonomic loss; (2) covariance of ...
Soil properties affecting corrosion and cathodic protection of steel in Texas soils
(1985)
Corrosion in the United States is a major economic problem with losses in 1984 estimated at $125 billion (Siebert, 1984). A larger portion of this corrosion can be attributed to degradation of underground metallic structures. ...
