Four-Fermion production at LEP using the OPAL detector
In 1997 LEP reached energies at which the production of heavy <br>gauge pairs of bosons was possible. Over 650 pb$^{-1}$ of <br>data have been analysed at centre-of-mass energies between 183 and 209 GeV. <br>Four-fermion final states stemming from decays of the Z$gamma^*$ into <br>$ <br>m q …

Analysis of Excited B Mesons with the OPAL Detector at LEP
A comprehensive high-statistics analysis of the low lying non-strange excited B meson states is performed. From 4 million hadronic <br>Z^0 decays recorded by the OPAL detector on and near to the Z^0 resonance, a sample of more than 570,000 inclusively reconstructed <br>B mesons is selected making …

Modeling of doubly-fed induction generators connected to distribution system based on eMEGASim® real-time digital simulator
… connected to a distribution system based on the OPAL-RT’s eMEGASim® real-time digital simulator. The system in this research consists of a 9 MW wind farm, an average SimpowerSystems® DFIG wind turbine, connected to a 13.8 kV IEEE 14 bus distribution network. A Simulink model was designed and …

The Development of New Tools to Investigate Alphavirus Replication Kinetics
Members of the alphavirus genus pose a serious or potential threat to public health in many areas of the world. Nearly all alphaviruses are maintained in nature by transmission cycles that involve alternating replication in a susceptible vertebrate and invertebrate host. The maintenance of this …

Improving the management of allergic disease in adults.
Historically, there has been a strong focus clinically and in research on the impact of allergy in children but not adults. It is often attributed to the idea that the nature of one’s allergy in childhood is fixed for life past a certain age. Subsequently, significant gaps have developed in how we …

Opal: In Vivo Based Preservation Framework for Locating Lost Web Pages
<p>We present Opal, a framework for interactively locating missing web pages (http status code 404). Opal is an example of "in vivo" preservation: harnessing the collective behavior of web archives, commercial search engines, and research projects for the purpose of preservation. Opal servers learn …

Measurement of Single W Production and Triple Gauge Boson Couplings in e+e- Collisions at sqrt(s)=161-189 GeV
Single W production in the e+e- --> qqbarenu reaction has been studied using a <br>data sample with an integrated luminosity of 251 pb-1 collected between 1996 and <br>1998 with the OPAL detector at LEP2. A sample of 92 events is selected in the <br>data, for a MC prediction of 87.6+/-3.7 events. …

Untersuchung von ZZ Endzustaenden mit dem OPAL-Detektor
The production of ZZ -> qqll events has been studied with the OPAL <br>detector at LEP. The analysis is based on 440 pb^-1 of data <br>recorded at six different centre-of-mass energies between 183 GeV and <br>202 GeV in the years 1997 to 1999. For each possible final state <br>(l = e, mu, tau) a …

Retroviral-Medicated Transfer of Suppressor tRNA Genes Into Human Cells
… with a variety of human diseases. A useful therapeutic approach to correct such mutations may be to introduce genes expressing suppressor tRNA that recognize the premature stop codon, insert the appropriate amino acid, and allow translation of a full-length, functional protein. Human opal …

Phosphors and photonic crystals
… Gd2O2S: RE phosphors have been prepared using the urea homogeneous precipitation method and firing. Stokes luminescence properties of Y2WO6: RE excited with a FRED (frequency doubled argon ion) UV laser (257 nm) have been studied. The emissions have been assigned to their corresponding energy …

Characterizing The Recognition Motif and Novel Substrates of Carm1
… protein arginine methyltransferases or PRMTs. These enzymes deposit one or two methyl groups to the nitrogen atoms of arginine side-chains. Elucidating the substrate specificity of each PRMT will promote a better understanding of which signaling networks these enzymes contribute to. Although …

EFFECTS OF MICROTEXTURAL INTERACTIONS OF ORGANICS AND SILICA ON SILICA DIAGENESIS
Opaline silica (opal-A) is thermodynamically unstable at surface conditions and readily transitions into opal-CT and at higher temperatures and pressures, quartz. Past work has used the temperature dependency of this phase transition for paleothermometry in opal-bearing sedimentary rocks. Those …

A Comparative Study of Conventional-Ligating and Self-Ligating Bracket Systems
<p>The purpose of this research was to determine the frictional resistance of four self-ligating brackets and two conventional bracket systems using two different types of orthodontic arch wires in both wet and dry fields. Six different brands of upper right central incisor brackets with 0.018-in …

Development of Microgrid Test Bed for Testing Energy Management System
<p>Today the world population has reached 7.5 billion, and this number is expected to grow at the rate of 1.13% every year [1]. With this increase in population, the total demand for electricity has also increased. More people means the need for more power: electricity to power homes, schools, …

Rational Fabrication of High-Performance and Scalable Opal Crystals for Thermo-Fluidic Applications
Inverse opals have continuously attracted interest as a scalable, ordered porous material capable of enhancing energy, fluid, mass, or ion transport in a wide variety of applications. In particular, in heat transfer applications they have been used as porous coatings for condensers and boilers for …

Metaphysics of Mania: Edgar Allan Poe's and Herman Melville's Rebranding of Madness during the American Asylum Movement
The “madman’s” place throughout history has tended to be a mystery on both ontological and epistemological levels. From the perception of the madman as a crazed oracle in the sixteenth century to the perception of the madman as a criminal in the seventeenth and eighteenth centuries, the …
