Thermal Feasibility Analysis Of Low Heat Rejection Engine, Peter Johnston Northrop

Open Access Theses

This thesis describes the computational fluid dynamics (CFD) directed analysis used to solve an overheating problem occurring during the warm up period of the crossbred ZKA26 engine in previous research. Internal combustion engine powered generator sets are the primary choice for worldwide operation. Of these generator sets, hardly any use internal combustion automobile engines that are modified beyond the specifications of the manufacturer. These specifications, while well qualified for their intended purpose, are poorly qualified for steady RPM operation as they are used in generator operation. This lack of qualification results in key losses of operational efficiency. This research effort …

Latino Catholicism And Indigenous Heritage As A Subfield Of Latino Studies: A Critical Evaluation Of New Approaches, Elizabeth C. Martinez Ph.D.

Religiosity In Constitutions And The Status Of Minority Rights, Brandy G. Robinson

Cultural Encounters, Conflicts, and Resolutions

Minority rights and religion have never been topics that are simultaneously considered. However, arguably, the two have relevance, especially when combined with the topic and theory of constitutionalism. Historically and traditionally, minorities have been granted certain rights and have been denied certain rights under various constitutions. These grants and denials relate to cultural differences and values, arguably relating to a culture’s understanding and interpretation of religion.

This article explores the relationship and status of minority rights as it relates to religiosity and constitutionalism. Essentially, there is a correlation between these topics and research shows where certain nations have used religion …

Left Ventricular Assist Device As Destination Therapy, Maya Guglin, Leslie W. Miller

The VAD Journal

Mechanical circulatory support is the most rapidly evolving strategy in heart failure management. The growing number of patients who need better results than medical therapy can offer, the limited pool of donors for cardiac transplantation, and several technological breakthroughs have all made the option of implanting a left ventricular assist device (LVAD) as destination therapy more important.

In this review, we outline the indications and decision making process of considering a patient for a destination therapy LVAD, as well as outcomes, complications, and issues related to management of patients on currently approved devices. The future direction of the field will …

Studying The Amount Of Angular Movement (Momentum) Of The Captain During Shooting And Its Contribution To The Values Of The Speed Of The Ball When Performing The Skill Of Shooting With The Hand Ball, Dergham Abdul Salem Nimah, Yarub Abdul Baqi Daikh

Modern Sport

The skill of shooting from a jump is considered one of the important and challenging skills, especially when the distance is long. In such cases, the player must face the goal to allow freedom in shooting, which requires specific movements in various body parts to change the player's speed, thereby increasing the ball’s speed. This increase in ball speed is crucial for shooting in certain situations. Therefore, it is essential to move certain body parts to generate speed, which is transferred to the ball. The speed in shooting results from the transfer of motion from the lower limbs to the …

The Effect Of Uphill And Downhill Exercises On The Balance Of Power In Terms Of The Electrical Activity Of The Working And Opposite Muscles Of Football Players, Maher Abdel Latif Aref, Safa Abdel Wahab Ismail

Modern Sport

Most coaches tend to focus in their training on developing only the agonist (working) muscles, without taking into account the importance of the antagonist muscles. However, many physiological theories indicate that the antagonist muscle should receive training at a rate of 70–75% of that given to the agonist muscle, in order to prevent physical problems that may affect the working muscle due to the lack of muscular support from the antagonist during training or matches. Based on this, the idea of the research emerged—to use uphill and downhill exercises due to their potential in developing strength balance between agonist and …

Evolutionary Genomics And Adaptive Evolution Of The Hedgehog Gene Family (Shh, Ihh And Dhh) In Vertebrates, Joana Pereira, Warren E. Johnson, Stephen J. O'Brien, Erich D. Jarvis, Guojie Zhang, M. Thomas P. Gilbert, Vitor Vasconcelos, Agostinho Antunes

Biology Faculty Articles

The Hedgehog (Hh) gene family codes for a class of secreted proteins composed of two active domains that act as signalling molecules during embryo development, namely for the development of the nervous and skeletal systems and the formation of the testis cord. While only one Hh gene is found typically in invertebrate genomes, most vertebrates species have three (Sonic hedgehog – Shh; Indian hedgehog – Ihh; and Desert hedgehog – Dhh), each with different expression patterns and functions, which likely helped promote the increasing complexity of vertebrates and their successful diversification. In this study, we …

Inductive Measurement Of Optically Hyperpolarized Phosphorous Donor Nuclei In An Isotopically Enriched Silicon-28 Crystal, P. Gumann, O. Patange, C. Ramanathan, H. Haas

Dartmouth Scholarship

We experimentally demonstrate the first inductive readout of optically hyperpolarized phosphorus-31 donor nuclear spins in an isotopically enriched silicon-28 crystal. The concentration of phosphorus donors in the crystal was 1.5×1015  cm−3, 3 orders of magnitude lower than has previously been detected via direct inductive detection. The signal-to-noise ratio measured in a single free induction decay from a 1  cm3 sample (≈1015 spins) was 113. By transferring the sample to an X-band ESR spectrometer, we were able to obtain a lower bound for the nuclear spin polarization at 1.7 K of ∼64%. The 31P-T2 measured with a Hahn echo sequence was …

Modeling, Fabrication, And Characterization Of Memristors, Anas Mazady

Doctoral Dissertations

The term “memristor” was coined by L. Chua from its two distinct functional characteristics, memory and resistor. From the symmetry argument of the circuit element and circuit variable matrix, memristor is deemed as the fourth fundamental circuit element, after resistor, capacitor, and inductor. Memristor switching and observed I-V characteristics are explained utilizing the underlying physics of the device in terms of the formation and rupture of filaments. Three different conduction mechanisms, namely - filament assisted tunneling current, bulk tunneling current and currents flowing through low and high conductivity filaments give rise to the total current in memristive systems. DC and …
