DUAL LANGUAGE LEARNERS IN PRESCHOOL: A MULTI-CASE STUDY ON HOW THE LANGUAGE ENVIRONMENT SUPPORTS LANGUAGE DEVELOPMENT
(2015)The increase of dual language learners in today’s classrooms have caused serious implications when examining how the country educates children (McWayne, Melzi, Schick, Kennedy, & Mundt, 2013). Because of the cultural and ... -
Dual-mode faculty's frame of reference and evolving approach to teaching over ITV: A phenomenological study.
(1999)Distance education used to mean the learner and teacher were separated by time and/or geography. The advent of telecommunications technologies has changed this typology. Now, teachers can teach their traditional students ... -
Dual-Porosity and Dual-Permeability Poromechanics Solutions for Problems in Laboratory and Field Applications
(2010)In this work, a study of anisotropic dual-porosity and dual-permeability poromechanics is presented through generalized analytical solutions for selected problems in laboratory and field applications. For example, the ... -

Dual-porosity approach to wellbore stability in naturally fractured reservoirs.
(2002)The naturally fractured reservoir was treated as a dual-porosity medium consisting of the primary rock matrix system and the fractured system. Assuming the matrix and fractures in the fractured medium to be 'separate and ... -
A dual-porosity model for two-phase flow in deforming porous media.
(1999)In this dissertation, an approach, which is based on the dual-porosity concept and takes into account rock deformations, is presented to derive rigorously a set of coupled differential equations governing the behavior of ... -
Dunes on the Navajo Uplands of Northeastern Arizona :
(1982)The study area is characterized by nearly horizontal, sedimentary, eolian, sandstone formations with scattered areas of shale. The climate is semi-arid and landforms consist primarily of broad open valleys. A variety of ... -
Durability of cementitiously stabilized aggregate bases for pavement application.
(2005)Cementitious stabilization has been extensively used to improve the performance of pavement materials. In the past, emphasis has been placed on observing the macromanifestation of stabilized pavement materials, but to the ... -
Duration of the Archimedes spiral after-effect under varied stimulus conditions /

Dust Formation and Destruction in Core Collapse Supernovae Explosions
(2024)Dust is a crucial component of the Interstellar Medium (ISM) and an important driver in many astrophysical processes. Dust formed from evolved stars increases the metallicity of the ISM, enriching it with heavier elements. ... -
Dwarf galaxies in N-body+SPH simulations
(2023-12)I present a study of various dwarf galaxies from N-body+SPH simulations in Lambda Cold Dark Matter cosmology. While the science results of this thesis pertain to dwarf galaxies of varying classifications and environments, ... -
DWI: Drinking While Indian. The Impact of Culture and Context on American Indian Drinking Behavior
(2011)American Indians have long been characterized as particularly susceptible to alcohol misuse and alcohol-related problems. Soon after initial contact with the indigenous populations of North America, European explorers and ... -
Dynamic adjustment in an idealized numerically-simulated bow echo.
(2002)While the large-scale atmosphere is governed by relatively simple dynamic balance relations that describe the mutual adjustment between the mass and wind fields (e.g., hydrostatic and geostrophic balances), no simple ... -
Dynamic behavior of bridge structures under moving loads and masses using differential quadrature method
(2009)The current study is focused on the dynamic behavior of an idealized highway bridge structure subjected to moving heavy vehicular loads using simplified representative models such as Euler beams and Kirchhoff plates. The ... -

DYNAMIC DRILLING FLUIDS LOSS AND FILTRATION: IMPACT OF DYNAMIC WELLBORE CONDITIONS AND WELLBORE STRENGTHENING IMPLICATIONS
(2018-12-14)Lost circulation (drilling fluid loss) and mud filtration have been investigated over the years because they lead to non-drilling time (NDT) and increase the overall well cost. It is usually the first source of damage to ... -
The dynamic heat transfer characteristics of a continuous agitated tank reactor /
(The University of Oklahoma., 1958) -
Dynamic optimization of service part inventory control policy through applied data mining and simulation.
(2007)This research defines a novel approach for associating inventory item behavior, focusing initially on demand patterns, with an optimal inventory control policy. This method relies upon the definition of typical service ...
