Dynamical Modelling of an Idealized Hemispherical Skull Model with Fluid Pressure Interactions Using Modal Analysis
(North Dakota State University, 2019)
In this dissertation, a non-invasive intracranial pressure (ICP) monitoring technique is introduced by developing a head dynamic model. The technique is based on modal frequency testing and vibration responses analysis of ...
Application of Cellulose Nanocrystals and Zinc Oxide as a Green Fire-Retardant System in High Density Polyethylene
(North Dakota State University, 2019)
Polymeric materials are widely used in diverse applications. However, a major weakness in the majority of the thermoplastic polymers is their lack of ability to resist fire. Most of the chemicals and additives currently ...
Bioprinting of Pancreatic Cancer Cells for Improved Drug Testing
(North Dakota State University, 2019)
Currently, many drugs are preclinically tested on two-dimensional cell cultures. However, this method does not adequately replicate the cellular interactions or diffusion gradient that occur in three-dimensional tissues, ...
Peer Crowd Affiliations as Predictors of Prosocial and Risky Behaviors Among College Students
(North Dakota State University, 2019)
College students often affiliate with similar peers, forming identity-based peer crowds. Research has shown that affiliations with certain peer crowds is associated with risky behaviors, thus derailing college success. ...
Supporting Youth Living in Family Homeless Shelters
(North Dakota State University, 2019)
Supporting youth living in family homeless shelters is important as these families face multiple barriers in their lives. Youth have many strengths that they build upon which can be useful as they bounce from home to home. ...
Identity Development and University Adjustment
(North Dakota State University, 2019)
Colleges and universities across the U.S. continue their efforts to enroll students from diverse backgrounds. Those students from lower socioeconomic (SES) backgrounds and first in their family to attend college have been ...
Theoretical and Computational Studies of the Mechanical Strength and Fracture Toughness of Adhesively Bonded Joints and Polymer Nanoclay Composites
(North Dakota State University, 2019)
Increasing use of adhesively bonded joints (ABJs) and polymer nanoclay composites (PNCs) in modern vehicles and other industrial sectors has deeply shaped the design and manufacturing of advanced materials and structures ...
Experimental Investigation of Molten Salt Torrefaction and the Development of a Lab-Scale Torrefaction Methodology
(North Dakota State University, 2019)
A novel torrefaction methodology using molten salts as a means to reduce torrefaction temperatures was investigated. A lab-scale molten salt torrefaction methodology was developed to consistently torrify biomass; involving ...
Numerical Analysis of a PV/Microchannel Integrated CO2 Direct-Expansion Heat Pump Water Heater
(North Dakota State University, 2019)
A steady-state numerical model of a PV/microchannel integrated direct-expansion CO2 heat pump (PV-DXHP) water heater is developed, validated, and analyzed in the present study. To accomplish the objectives, a numerical ...
Longitudinal Associations among Personality, Perceived Control, and Health for American and Japanese Aging Adults
(North Dakota State University, 2019)
Perceived control is associated with health throughout adulthood, yet has also been found to decline with age possibly due to age-related experiences of increasing losses and limitations in life circumstances. Perceived ...
