Junction Based Gallium Nitride Power Devices
… breakdown voltage. We proposed to use the junction-based structure in GaN power devices to address the above problems and fully exploit GaN's material properties. The first part of this dissertation characterizes nickel oxide (NiO) as a p-type material to construct the junction-based GaN …

An accurate junction circulator design procedure
A novel circulator design method is presented. It utilizes H. Bosma’s suggested electrical model, a program written for a digital computer representing this model, Fay & Comstock’s design method to calculate electrical and physical properties of applied ferrite cylindrical resonators and measured …

Roles Of Neuregulin1 In Neuromuscular Junction Development
<p>Neuromuscular junction (NMJ) development is a multistep process mediated by coordinated interactions between nerve terminals, target muscles, and peri-synaptic glial cells, and thus requires reciprocal signals derived from every cell type. Neuregulin1s (NRG1s) are a family of predominantly …

Single Molecule Junction Conductance and Binding Geometry
… properties of single organic molecule-metal junctions. Using a Scanning Tunneling Microscope (STM) we image, probe energy-level alignment and perform STM-based break junction (BJ) measurements on molecules bound to a gold surface. Using Scanning Tunneling Microscope-based break-junction …

Junction Specificity and Transmembrane Linkages of Integrins
… P4B2, which localizes to multiple adhesion junctions, namely, a subset of focal adhesions, the Z-disc of muscle, and neuromuscular junctions. Immunopurification of the antigen to this antibody from chicken brain tissue yielded a complex of three prominent proteins with mobilities of 36, 30 …

The triple-helical DNA four-way junction
… strands can be incorporated into the four-way junctions combining the properties of the triple helices and those of branched structures within one system without compromising either of the two. It is now known that folding into secondary and tertiary structures by nucleic acids is crucial for …

Shock wave interaction in a tee junction
… the unsteady shock wave interaction at a tee junction, and to measure the transmitted shock strength. Two tee junctions of different cross-sectional shape were constructed, and instrumented with three piezoelectric pressure transducers and two hot wire anemometers. Tests were run in air for a …

Hydraulic model study of a manhole junction
The object of this investigation was the experimental investigation of the hydraulics of a flow-through manhole with one lateral connection. An attempt was made to use the conservation of momentum principle to develop a mathematical relationship which satisfied the data obtained in the model study. …

Dysfunction junction intelligence, peacekeeping, and the United Nations
United Nations peace operations continue to play a vital role in international security, with 15 missions underway in 2007. The UN, however, lacks the institutional intelligence capacity to provide guidance, high-level assessments, and tactical/operational intelligence support for the over 100,000 …

Phenotypic characterization of hangover at the neuromuscular junction
Ethanoltoleranz beruht vermutlich auf Veränderung in synaptischer Plastizität; da die Mechanismen, die zu dieser Anpassung der Synapsen führen, in hang-Mutanten offensichtlich defekt sind, war es Ziel dieser Arbeit zu erklären, wie HANG zu synaptischer Plastizität beiträgt. In diesem Zusammenhang …

Heat Transfer Enhancement Using Tip and Junction Vortices
This research is important in compact heat exchanger design. Enhancing heat transfer can lead to smaller, more efficient heat exchangers in a broad range of applications. A simplified heat exchanger performance evaluation method is considered to explore the heat transfer benefit and pressure-drop …

The development of magnetic tunnel junction fabrication techniques
… magnetoresistance (MR) in magnetic tunnel junctions in 1995 sparked great interest in these devices. Their potential applications include hard disk read head sensors and magnetic random access memory (MRAM). However, the fabrication of repeatable, high quality magnetic tunnel junctions is …

The junction: transcending sociotechnical divides through youth space
Infrastructure continues to perpetuate the effects of splintering urbanism in South African cities. Where apartheid planning policies such as the group areas act used infrastructure as a mechanism of social organisation, this design dissertation proposes using architecture as social infrastructure …

T-junction resonant modulators and detectors in CMOS
… idea is proposed for optical modulators - T-junction. The T-junction allows to decouple the Extinction Ratio from the Bandwidth and to optimize each separately. Initial T-junction modulator provides an increase in bandwidth - 13 GHz versus 3 GHz, for the previous designs. An analytical model …
