Effects of two types of nursing homes on the behaviors of their residents with dementia : a descriptive comparative analysis
(1991)
The purpose of this descriptive comparative study was to simultaneously and systematically assess and evaluate two representative types of nursing home environments [an integrated nursing home (INH) in Central Louisiana ...
The Determination and Error Assessment of the Earth's Gravity Field Model
(1991-05)
Precision orbit determination methods, along with a new technique to compute
relative data weights, have been applied to the determination of the Earth’s gravity field and
other geophysical parameters from the combination ...
Memory functioning in panic disorder : a neuropsychological investigation
(1991)
Recent psychological and neurological studies of patients with anxiety disorders suggest that memory functioning may be impaired in patients with panic disorder. The suggested means by which memory may be impaired, however, ...
Estimating the latent trait from Likert-type data : a comparison of factor analysis, item response theory, and multidimensional scaling
(1991)
Seven statistical procedures were compared with one another in terms of the ability to recover a unidimensional latent trait from Likert-type data. They are factor analysis based on either Pearson correlations (FA-PR) or ...
Stability of Thin Aqueous Films on Solid Surfaces
(1991-12)
The objective of this work is to gain insight into the influence of aqueous wetting films on reservoir wettability and on the transport and distribution of the wetting phase in porous media. Theoretical and experimental ...
Development of a Thermodynamically Consistent, Fully Implicit, Composittonal, Equation-Of-State, Steamflood Simulator
(1991-05)
A thermodynamically consistent, three-dimensional, fully implicit, compositional, equation-of-state, steamflood simulator is developed. The formulation uses a single set of primary variables-overall component mole numbers, ...
Evolution of stocks and massifs from burial of salt sheets on the continental slope, northern Gulf of Mexico
(1991)
Data from conventional two- and three-dimensional seismic surveys and wells were used to analyze the morphology of salt structures and to determine the history of salt emplacement in a 1,500 mi² (3,850 km²) region of the ...
A Numerical Study of the Performance of Unstable Displacements in Heterogeneous Media
(1991-08)
The finite difference method (FDM) and the finite element method (FEM) are the commonly used numerical methods in reservoir simulation. The first objective of this study was to perform a detailed comparison of the two ...
A Model for Particle Deposition and Filter Cake Buildup in Granular Media
(1991-12)
The objective of this work is to develop a general technique for a better quantitative understanding of particle deposition that can be applied for studying particle deposition under as few assumptions, regarding the ...
Experimental Studies of Wellbore Stability in Shale Formations
(1991-08)
This study presents a shale/drilling fluid interaction Martin E. Chenevert Robert S. Schechter model developed to explain mechanisms. The model uses total pressure concepts and diffusivity equation to predict shale swelling ...
