Dark matter signals in deflected mirage mediation

We investigate the parameter space of a specific class of model within the deflected mirage mediation (DMM) scenario. We look at neutralino properties and compute the thermal relic density as well as interaction rates with xenon direct detection experiments. We find that there are portions of the parameter space which are in line with the current WMAP constraints. Further we find that none of the investigated parameter space is in conflict with current bounds from the Xenon10 experiment and that future large-scale liquid xenon experiments will probe a large portion of the model space.Comment: 4 pages, contribution to proceedings for SUSY0

A pilot study of the relations within which hearing voices participates : towards a functional distinction between voice hearers and controls

The current research used the Implicit Relational Assessment Procedure (IRAP) as a preliminary step toward bringing a broad, functional approach to understanding psychosis, by focusing on the specific phenomenon of auditory hallucinations of voices and sounds (often referred to as hearing voices). On this path, we created a taxonomy of some critical features of voice hearing based on the existing literature (i.e., perceived normality of voices, appraisals of self and other people hearing voices, and fear of voices) as a focus of our experimental manipulations. It was our hope that our findings would add to the broad literature that has used explicit measures to study these phenomena, and that the use of an 'implicit' measure might assist toward a functional analytic understanding. Three pilot studies were conducted to assess the relations within which hearing voices participates in non-clinical voice hearers (i.e., individuals who hear voices but have no clinical diagnosis or distress) and compared to non-voice hearing control participants. The IRAP effects demonstrated both positive and negative relational responses across the three studies, and these effects varied according to explicit levels of delusional ideation. Furthermore, these IRAP effects also predicted explicit aspects of voice hearing and well-being. The current set of pilot studies demonstrate the utility and precision of the IRAP in this domain, and we propose that this type of experimental analysis may hold potential for future bottom-up functional analyses of voice hearing

Using the IRAP to explore natural language statements

This study explored a modification to the typical presentation of label and target stimuli on Implicit Relational Assessment Procedure (IRAP) effects. We asked whether combining the labels and targets into a single phrase would influence performances. The key purpose of the study was to determine the feasibility of altering the way in which stimuli are presented within the IRAP, so as to potentially employ more complex natural language-like statements in future research. In the Typical IRAP employed here, labels and targets were presented as separate words, while in the Natural Language IRAP they were combined to form a single statement. The results demonstrated no substantive differences in the effects recorded on both types of IRAP, thus supporting the future use of a Natural Language version

Development of optimized, graded-permeability axial groove heat pipes

Heat pipe performance can usually be improved by uniformly varying or grading wick permeability from end to end. A unique and cost effective method for grading the permeability of an axial groove heat pipe is described - selective chemical etching of the pipe casing. This method was developed and demonstrated on a proof-of-concept test article. The process improved the test article's performance by 50 percent. Further improvement is possible through the use of optimally etched grooves

A NEW “FERROVUM” SPECIES IN A SCHWERTMANNITE-PRODUCING PLANT FOR MINE WATER TREATMENT

Mining activities for metals or coal often result in the development of acid mine drainage due to the oxidation of sulfidic minerals which get exposed to oxygen. The acidic mine waters are characterized by low pH, high concentrations of sulfate and ferrous iron, and possibly dissolved heavy metals or metalloids. Conventional treatment comprises neutralization and oxidation yielding a sludge of iron oxides/hydroxides
