The Five Factor Forgiveness Inventory: A Measure of Forgiveness from the Perspective of the Five Factor Model

The purpose of this study was to develop and validate a five factor model (FFM) measure of forgiveness. Participants were 545 undergraduates currently enrolled in introductory and experimental psychology courses at the University of Kentucky (272 used for item construction, 273 for scale validation). Items were selected on the basis of convergent validity with five-factor model personality scales and forgiveness scales. Participants in the validation stage were administered the resulting Five Factor Forgiveness Inventory (FFFI), as well as the International Personality Item Pool-NEO (IPIP-NEO) and seven other existing forgiveness measures. Significant convergent validity was obtained for the vast majority of the seven FFFI subscales with their corresponding IPIP-NEO facet scales. Discriminant validity was good to excellent for all subscales, as well. FFFI subscales were all significantly correlated with the seven existing forgiveness measures, and the FFFI total score obtained significant incremental validity over all seven other forgiveness scales. Finally, multiple regression analyses revealed that FFFI scales accounted for additional variance in predicting results on existing forgiveness measures. The initial construction and validation of this measure provides a foundation for assessing forgiveness from the perspective of the FFM, thus providing a more comprehensive, nuanced understanding of the disposition to forgive

Simulations of agglomerate sedimentation and suspension

Mineral wool insulation material applied to the primary cooling circuit of a nuclear reactor maybe damaged in the course of a loss of coolant accident (LOCA). The insulation material released by the leak may compromise the operation of the emergency core cooling system (ECCS), as it maybe transported together with the coolant in the form of mineral wool fiber agglomerates (MWFA) suspensions to the containment sump strainers, which are mounted at the inlet of the ECCS to keep any debris away from the emergency cooling pumps. In the further course of the LOCA, the MWFA may block or penetrate the strainers. In addition to the impact of MWFA on the pressure drop across the strainers, corrosion products formed over time may also accumulate in the fiber cakes on the strainers, which can lead to a significant increase in the strainer pressure drop and result in cavitation in the ECCS. Therefore, it is essential to understand the transport characteristics of the insulation materials in order to determine the long-term operability of nuclear reactors, which undergo LOCA. An experimental and theoretical study performed by the Helmholtz-Zentrum Dresden-Rossendorf and the Hochschule Zittau/Görlitz is investigating the phenomena that maybe observed in the containment vessel during a primary circuit coolant leak. The study entails the generation of fiber agglomerates, the determination of their transport properties in single and multi-effect experiments and the long-term effects that particles formed due to corrosion of metallic containment internals by the coolant medium have on the strainer pressure drop. The focus of this presentation is on the numerical models that are used to predict the transport of MWFA by CFD simulations. A number of pseudo-continuous dispersed phases of spherical wetted agglomerates can represent the MWFA. The size, density, the relative viscosity of the fluid-fiber agglomerate mixture and the turbulent dispersion all affect how the fiber agglomerates are transported. In the cases described here, the size is kept constant while the density is modified. This definition affects both the terminal velocity and volume fraction of the dispersed phases. Application of such a model to sedimentation in a quiescent column and a horizontal flow are examined. The scenario also presents the suspension and horizontal transport of a single fiber agglomerate phase in a racetrack type channel

Coat Weight Predictions on the Cylindrical Laboratory Coater

Paper Coating attempts to create a smooth and even surface for improved optical and printing sheet performance. Trials were conducted using a blade application on a Cylindrical Laboratory Coater. Two different blade extensions were analyzed. These extensions were key variables that influenced blade forces. Currently, to achieve a range of coat weights on a sheet, only the trial and error method is performed during a run. The future goal in mind was to have a computer simulation that could make predictions of coat weights without performing the actual trial. This study was conducted to lay the groundwork for future analysis in hope of achieving this long range goal. A modeling technique was used to relate actual data to predictive data. From this technique, a positive correlation existed between actual data and modeling expectations. The best correlation was due to highly constrained geometries resulting from high run-in settings over the small blade extension. For future study, it is quite possible to establish a computer simulation technique, but it would have to be paper substrate specific and require numerous trials to eliminate all deviations

The Effects of Environment, Feed Form and Dietary Caloric Density on Broiler Performance; and Effect of Variable CatP Ratio and Phytase on Growth performance and Mineral Deposition in Corn-Soy Diets fed to Straight-run Broilers

The objective of the first study was to assess the effect of variations of feed form and dietary caloric density on production and immunity parameters in broilers reared on clean shavings and built-up litter. Treatments were arranged in a 2 x 2 factorial randomized block design within a split plot. Whole plot treatments considered one room (11 x 7.32m) of either clean shavings or built-up litter; divided into 16 treatment replications of either standard (30%) or improved (80% feed form), and 16 replications of either commercial or increased (+110 kcal/kg) dietary caloric density comprising the 2 x 2 factorial arrangement. Broilers consuming an improved feed form demonstrated an improved feed intake (FI), live weight gain (LWG), feed conversion ratio (FCR), breast weight and breast yield (p \u3c 0.05). Providing an improved feed form demonstrated an increased concentration in IgG (p \u3c 0.05). An environment x energy interaction (p \u3c 0.05) demonstrated increased concentration of IgG in broilers fed a commercial energy reared in a built-up litter environment, whereas broilers maintained a similar IgG concentration when fed an increased energy regardless of environment. Linear contrasts demonstrated that broilers provided improved feed form at commercial energy increased FI and LWG (p ≤ 0.05), while maintaining FCR (p \u3e 0.05) compared to broilers provided standard feed form at increased energy regardless of environment. These data suggest feed form improvements may partition energy towards growth more than feeding an increased energy diet.;The objective of the second study was to assess the effect and potential for interaction of corn/soy diets containing variable Ca/tP ratios and phytase inclusions on straight-run broiler performance and mineral deposition. A positive control was compared to 12 treatment combinations comprised of a 4 x 3 factorial arranged in a randomized complete block design. Main effects consisted of four Ca/tP ratios (1.0, 1.2, 1.4, and 1.6) and three inclusions of phytase (low ≈ 1,000, medium ≈ 2,000, and high ≈ 3,000 FTU/kg). All diets were steam conditioned at 82°C for 10s and extruded through a 4.7 x 38 mm pellet die. Diets were crumbled via roller mill for starter (d 1-14) and grower (14-28) growth phases and left as intact pellets for the finisher phase (28-42). Straight-run Hubbard x Cobb 1-day-old broiler chicks were obtained from a commercial hatchery and randomly assigned to floor pens (0.69 x 2.4 m) at a density of 0.06 m2/bird (23 birds/pen) with feeder access space of 1.2 cm/bird. Seven replicate pens of broilers were fed one of 13 dietary treatments for 42 days. Tibia extraction and total GI tract digesta were collected on d 28. Higher phytase inclusions increased LWG (p = 0.0166) and decreased FCR (p = 0.0016) in the starter growth phase. Increasing Ca/tP decreased LWG (p = 0.0005) in the grower phase. High phytase inclusion demonstrated a decreased LWG (p = 0.0428) in the finisher phase. Phytase inclusion and Ca/tP ratio interacted for starter FI (p \u3c 0.05) and demonstrated a trend of interacting for finisher and overall FI (p = 0.1). In general, higher feed intakes were associated with high inclusions of phytase in diets with a 1.4 Ca/tP ratio. Overall growth performance was not significantly affected by treatment (p \u3e 0.05). Mineral digestibility was improved when Ca/tP decreased (p \u3c 0.05) and phytase inclusion increased (p \u3c 0.05). Bone mineralization measures in general showed improvement at a Ca/tP ratio higher than 1.0 (p \u3c0.05). Based on these data; broiler performance and mineral deposition was optimized for 1.2 and 1.4 Ca/tP ratio and phytase inclusions above 1,000 FTU/kg

The study entails the generation of fiber agglomerates, the determination of their transport properties in single and multi-effect experiments and the long-term effects that particles formed due to corrosion of metallic containment internals by the coolant medium have on the strainer pressure drop. The focus of this presentation is on the numerical models that are used to predict the transport of MWFA by CFD simulations in the containment sump. Two dispersed phases were conditions to determine the influence of entrained air from a jet on the transport of fibre agglomerates through the sump. The strainer model of A. Grahn was implemented to observe the impact that the accumulation of the fibres have on the pressure drop across the strainers. The geometry considered is similar to the containment sump configurations found in Nuclear Power Plants

Empirical modelling and simulation of transmission loss between wireless sensor nodes in gas turbine engines

Transmission loss measurements between a grid of hypothetical WSN node locations on the surface of a gas turbine engine are reported for eight frequencies at 1 GHz intervals in the frequency range 3.0 to 11.0 GHz. An empirical transmission loss model is derived from the measurements. The model is incorporated into an existing system channel model implemented using Simulink as part of a wider project concerning the development of WSNs for the testing and condition monitoring of gas turbine engines

D−DˉD-\bar{D} mixing constraints on FCNC with a non-universal Z′Z^\prime

The BaBar and Belle collaborations have recently reported evidence for $D^0-\bar D^0$ mixing. This measurement provides the first significant constraint on FCNC in the up-quark sector for non-universal $Z^\prime$ models. Attributing the observed $D-\bar D$ mixing to new physics, we comment on the resulting rare $D$ and $t$ decays. We also show that a CP violating semileptonic asymmetry as large as $\sim 30$ is allowed by the experimental results.Comment: RevTex, 10 pages, 1 figure. Several typoes correcte
