Dahl friction modeling
… have been suggested, but variations of the Dahl solid friction model remain some of the simplest yet most useful. Dahl's original theory proposed that friction behaved as a stress acting upon the quantum mechanical bonds at the interface. Thus, the relationship between frictional force and …

Differences in the expression of opioid peptides in Dahl salt-resistant and salt-sensitive rats
The Dahl strain of genetically salt-resistant (R) and salt-sensitive (S) rats affords an opportunity to explore mechanisms for the development of hypertension and the consequences, as well as sensitivity or resistance, of salt-induced hypertension. Because of the evidence that opioid peptides and …

Cellular pathways of angiotensin II signalling in the hypertrophic myocardium
… that these are identifiable in the heart of the Dahl salt-sensitive rat. The aim of the present study was to determine ATII intra-cellular signalling of the hypertrophic cardiac myocyte. Ventricular hypertrophy in the Dahl SS/Jr (Dahl S) rat was dependent upon the time on 6% NaCl diet. This was …

The child and the adult in contemporary children's literature : Roald Dahl, Anne Fine, Diana Wynne Jones, J. K. Rowling
… the thesis, I examine the way in which Dahl, Fine, Jones and Rowling engage with (or react against) these contemporary childhood issues. Chapter one outlines the social context and provides information on the most prominent issues: children's rights; parenting advice and educational …

Role of the renal nerves in hypertension
… same effect on blood pressure in hypertensive Dahl salt-sensitive (S) rats as has been reported in clinical trials. I then developed and validated a novel method for selective ablation of afferent renal nerves (renal-CAP treatment). Using this method, I showed that afferent renal nerves are not …

The Impact of Competition on Congressional Behavior
… theorists such as Seymour Martin Lipset, Robert Dahl, and V. O. Key, periodic free elections are not by themselves enough to ensure the responsiveness of public officials. One crucial condition must also be present--competition. Competition is assumed to make political leaders responsive to the …

Techniques for handling nonsymmetric cones in interior point algorithms
… is necessary for the alternative algorithm by Dahl and Andersen (2021) that is implemented by the solver MOSEK. We implement the stepping procedure described by Dahl and Andersen (2021) in Hypatia and make some empirical comparisons between MOSEK's algorithm and Hypatia's.

A phylogeny of the genus Gasteracantha Sundevall, 1833 (Araneae, Araneidae) with an examination of sexually dimorphic characters in the subfamily Gasteracanthinae
… work on Gasteracantha since the studies by Dahl (1914) and Emerit (1974). By using both molecular and morphological cladistic analyses, the most comprehensive phylogeny to date of Gasteracantha, and the related genera, is inferred. By supplementing specimens from worldwide institutional …

Modelling of Long and Short Term Blood Pressure Control Systems
… the process of salt-induced hypertension in Dahl rats. The models successfully replicate the multiphasal response of blood pressure to high salt intake and provide information on the magnitudes and time scales of the various response components. The renal vasculature response to sympathetic …

Neural mechanisms promoting G-alpha-i2 protein dependent salt sensitive hypertension in the Sprague-Dawley rat
… and normotension. In contrast, in the Dahl Salt Sensitive (DSS) rat, and in salt resistant rats in which this protein is experimentally downregulated, our laboratory has identified the development of renal nerve-dependent sympathoexcitation and salt-sensitive hypertension (ssHTN). …

A Journey Of Teaching And Learning In Science Education: The Microculture Of Emerging Inquiry-based Science Instruction In An Urban, Low Socioeconomic Elementary School Science Lab
This ethnographic study of emerging inquiry-based science instruction in an urban, low socioeconomic elementary school science lab was designed to gain insight into the perspectives of the teacher and students. The study involved a Central Florida elementary school whose population was over 80 …

Vocal responses of Blue Jays (Cyanocitta cristata) to raptors that differ in predatory threat
<p>Anti-predator defense is an important adaptation in group-living organisms. Some species of flocking birds use referential calls to communicate predator presence and the level of threat posed by predators. Previous studies have revealed that two species in the corvid family, American Crows …

Real-Time Object Removal in Augmented Reality
<p>Diminished reality, as a sub-topic of augmented reality where digital information is overlaid on an environment, is the perceived removal of an object from an environment. Previous approaches to diminished reality used digital replacement techniques, inpainting, and multi-view homographies. …

The admission process : how portfolio assessment establishes the pedagogic subject of fashion design
This research draws on the work of Basil Bernstein as a theoretical structure with which to investigate the entry selection process that assesses prospective fashion design students' portfolios. It will be revealed how the three interrelated rules of the pedagogic device, namely distributive, …

Development of Structures and Methods for Safe On Orbit Robotic Assembly of Small Satellites
While the advent of small satellites such as CubeSats have allowed for space to become quicker and easier to access, the turn-around time is still insufficient for rapid deployment. Example situations are replacing nodes in large constellations, time-sensitive science experiments, or disaster …

Social media engagement among early adolescents: Motivational and adjustment correlates
… Based on hormonal activation theory (Forbes & Dahl, 2010), I focused on pubertal and social goal correlates of individual differences in social media engagement among adolescents. I also examined positive (prosocial support) and negative (peer victimization, internalizing problems) adjustment …
