Scanner
An aerial vehicle rotating in gyroscopic fashion about one of its axes has an optical system which scans an area below the vehicle in determined relation to vehicle rotation. A sensing device is provided to sense the physical condition of the area of scan and optical means are associated to direct the physical intelligence received from the scan area to the sensing means. Means are provided to incrementally move the optical means through a series of steps to effect sequential line scan of the area being viewed keyed to the rotational rate of the vehicle
Development of a Measure of Craving Suppression
While there is evidence to support the efficacy of mindfulness-based treatment for substance use, the mechanisms through which they lead to therapeutic outcomes have received less attention. A growing body of literature suggests that the ways in which people respond to cravings may be an important mediator of change. Individuals with substance use problems may use them to cope with or avoid negative experiences, which could include the experience of craving itself. Thought suppression in particular has been investigated as a specific form of experiential avoidance, and findings suggest that thought suppression strategies may interfere with attempts to quit using substances.
While mindfulness training should be expected to reduce the tendency to suppress or avoid cravings, evidence to support this expectation is limited, largely because no measures yet exist that assess the suppression of craving. Therefore, the purpose of the present study was to develop a self-report measure of the suppression of craving.
Existing measures of other types of thought suppression and experiential avoidance were examined to identify items that could be adapted for use in the Craving Suppression Scale (CSS). To assist with the item development process, a focus group was also conducted at a local residential treatment facility. Participants were asked to discuss what they do when they are experiencing cravings and what thoughts go through their minds when cravings come up. Their responses were used to guide content development for the CSS items. Items were developed for two sub-scales: suppression of craving and beliefs about craving.
Items were administered to a sample of inpatients in substance use treatment and an online sample of individuals reporting current or previous substance use problems (total N = 208). Factor analysis of the remaining items supported a two-factor structure for the CSS as hypothesized. Relationships were examined between the CSS and other measures of other forms of experiential avoidance/suppression, craving, and emotional distress. The CSS scales correlated well with other measures of suppression but had mixed relationships with other constructs of interest. Evidence for the validity and potential utility of the CSS are discussed along with theoretical and treatment implications
Developing an On-Line Interactive Health Psychology Module.
On-line teaching material in health psychology was developed which ensured a range of students could access appropriate material for their course and level of study. This material has been developed around the concept of smaller 'content chunks' which can be combined into whole units of learning (topics), and ultimately, a module. On the basis of the underlying philosophy that the medium is part of the message, we considered interactivity to be a key element in engaging the student with the material. Consequently, the key aim of this development was to stimulate and engage students, promoting better involvement with the academic material, and hence better learning. It was hoped that this was achieved through the development of material including linked programmes and supporting material, small Java Scripts and basic email, forms and HTML additions. This material is outlined as are some of the interactive activities introduced, and the preliminary student and tutor experience described
Easily fabricated ion source for characterizing mixtures of organic compounds by direct analysis in real time mass spectrometry
The increasing use of atmospheric pressure mass spectrometry has led to the development of many ambient ionization sources, for which sampling versatility and low cost are desired features. One such recent ambient ionization method is direct analysis in real time mass spectrometry (DART-MS), which has proven to be well suited to the analysis of native samples of both simple and complex natures. We describe a home-built DART source (EZ-DART) with versatile sampling capabilities, low power requirements, and low assembly cost which can be easily interfaced to mass spectrometers equipped with an atmospheric pressure inlet. The operating temperature range (22–250 °C) enables the acquisition of both temperature programmed desorption-based DART mass spectra and the collection of multistep collision-induced dissociation (CID) mass spectra. We present here the validation of the EZ-DART source and a demonstration of its performance in a number of relevant applications. Additionally, we introduce the new DART application of reagent assisted desorption ionization (RADI) for the targeting of specific chemical functionality in complex organic mixtures through a host–guest chemical system
Doping Evolution of Magnetic Order and Magnetic Excitations in (SrLa)IrO
We use resonant elastic and inelastic X-ray scattering at the Ir- edge
to study the doping-dependent magnetic order, magnetic excitations and
spin-orbit excitons in the electron-doped bilayer iridate
(SrLa)IrO (). With increasing
doping , the three-dimensional long range antiferromagnetic order is
gradually suppressed and evolves into a three-dimensional short range order
from to , followed by a transition to two-dimensional short range
order between and . Following the evolution of the
antiferromagnetic order, the magnetic excitations undergo damping, anisotropic
softening and gap collapse, accompanied by weakly doping-dependent spin-orbit
excitons. Therefore, we conclude that electron doping suppresses the magnetic
anisotropy and interlayer couplings and drives
(SrLa)IrO into a correlated metallic state hosting
two-dimensional short range antiferromagnetic order and strong
antiferromagnetic fluctuations of moments, with
the magnon gap strongly suppressed.Comment: 6 Pages, 3 Figures, with supplementary in Sourc
Anisotropic softening of magnetic excitations in lightly electron doped SrIrO
The magnetic excitations in electron doped (SrLa)IrO with
were measured using resonant inelastic X-ray scattering at the Ir
-edge. Although much broadened, well defined dispersive magnetic
excitations were observed. Comparing with the magnetic dispersion from the
parent compound, the evolution of the magnetic excitations upon doping is
highly anisotropic. Along the anti-nodal direction, the dispersion is almost
intact. On the other hand, the magnetic excitations along the nodal direction
show significant softening. These results establish the presence of strong
magnetic correlations in electron doped SrLa)IrO with close
analogies to the hole doped cuprates, further motivating the search for high
temperature superconductivity in this system
