Patient experiences with group behavioral activation in a partial hospital program

Background: Behavioral activation (BA) is an evidence-based treatment for depression that has been primarily delivered in individual outpatient treatment. Prior research supports a positive participant experience in individual therapy; however, less is known about the patient experience in group therapy, which is common in acute psychiatric settings.Aims: The present study examined the patient experience of Brief Behavioral Activation Treatment for Depression (BATD) delivered in group acute psychiatric treatment.Method: We used thematic analysis to extract themes from feedback surveys administered as part of quality improvement practice at a partial hospital program. Survey questions explored what patients learned, liked, disliked, and thought could be improved in the BATD groups. Three individuals independently coded survey responses and collaboratively developed categories and themes.Results: Themes included several helpful content areas (e.g., value-driven activities, increasing motivation, goal setting, activity scheduling, cognitive-behavioral model, self-monitoring) and learning methods (e.g., group format, experiential exercises, worksheets). Patients also identified unhelpful content (e.g., specific focus on depression and listing activities by mood). There was mixed feedback regarding the repetition of material and balance of lecture versus group participation.Conclusion: Overall, these findings suggest a mostly positive patient experience of group-delivered BATD and support the acceptability of group-delivered BATD as a component of short-term intensive treatment.
1,2-Propylene Glycol: A Biomarker of Exposure Specific to e-Cigarette Consumption

Over the past decade, new emerging tobacco and nicotine-delivery products have changed the tobacco landscape. Especially, electronic cigarettes (ECs) have been suggested to be considered for tobacco harm reduction, reinforcing the need to identify novel biomarkers of exposure (BoE) specific to the EC use as this would complement exposure assessment and product compliance monitoring. Therefore, a sensitive LC-MS/MS method for the quantification of 1,2-propylene glycol (PG) and glycerol (G), the main e-liquid constituents, was established. PG and G were analyzed in plasma and urine samples from a clinical study comparing five nicotine product user groups, users of combustible cigarettes (CC), electronic cigarettes (EC), heated tobacco products (HTP), oral tobacco (OT), and oral/dermal nicotine delivery products (used for nicotine replacement therapy, NRT) with a control group of non-users (NU). Data demonstrate significantly elevated PG levels in urine and plasma in EC users compared to users of CC, HTP, NRT, OT as well as NU. In addition, PG in plasma and urine of vapers significantly correlated with nicotine (plasma) and total nicotine equivalents (urine), biomarkers reflecting product consumption, emphasizing the high specificity of PG as a BoE for EC consumption. We therefore suggest the use of PG as BoE in urine and/or plasma in order to monitor EC use compliance in exposure assessments.
Involvement of the dorsal striatum in the processing of happy faces in Borderline Personality Disorder

Background Emotion dysfunction and anhedonia are main problems in borderline personality disorder (BPD). In the present functional MRI (fMRI) study, we investigated neural activation in the processing of happy faces and its correlates with habitual emotion acceptance in patients with BPD. Methods 22 women with BPD and 26 female healthy controls watched movie clips of happy and neutral faces during fMRI without any instruction of emotion regulation. To associate neural activation with habitual emotion acceptance, we included individual scores of the Emotion Acceptance Questionnaire (EAQ) as a covariate in brain data analysis. Results All participants showed amygdala, temporal and occipital activation in the processing of happy compared to neutral faces. Additionally, healthy controls showed activation of the hippocampus and patients with BPD showed dorso-striatal (caudate, putamen) activation in the happy compared to the neutral condition. Compared with healthy controls, patients with BPD showed significantly more caudate activation. We could not find significant correlations with the EAQ. Conclusions Our results indicate caudate hyperactivation in patients with BPD during the processing of happy faces. Although patients reported significantly less emotion acceptance of positive emotions, an association with neural activation was not detectable.
Experimental study on shear behavior of carbon-fiber-reinforced polymer reinforced concrete short beams without web reinforcement

Recent literature emphasized the scarcity of information on the shear behavior of fiber-reinforced polymer (FRP) reinforced concrete short beams and the need to develop sufficient experimental data in this area. The present study responds to this need by conducting shear force testing on eight concrete short beams reinforced with carbon-fiber-reinforced polymer (CFRP) and four control concrete beams reinforced with steel. To ensure a shear failure, all tested beams were reinforced with only bottom longitudinal reinforcement and no web reinforcement was provided. The crack pattern, reinforcement strain, mode of failure, and shear strength and deflection of tested beams were studied. The influence of the shear span to effective depth ratio, a/d, beam effective depth, d, longitudinal reinforcement ratio, ρ, and concrete compressive strength, f ′c on the shear behavior of CFRP-reinforced concrete short beams was examined. It was observed that the experimental parameters investigated had a significant effect o.
Learning from productive failure

I advance a theoretically and empirically-grounded case for designing for and learning from failure, and instantiate it in a learning design called Productive Failure (PF). I describe the key mechanisms and the design principles of PF. The PF learning design comprises a generation and exploration phase followed by a consolidation and knowledge assembly phase. Findings show that the PF learning design is more effective in developing conceptual understanding and transfer than a direct instruction design. Follow-up studies are described wherein key aspects of the productive failure design were tested over multiple classroom-based studies as well as controlled experiments, and how these studies helped us interrogate and understand the criticality of key mechanisms embodied in the PF design. Implications for the learning theory and the design of instruction are discussed by situating findings in the long-standing instructivist-constructivist debate.
The Influence of Cross Angle on the Flow Ripple of Axial Piston Pumps by CFD Simulation

This paper studies the flow pulsation of axial piston pumps of different cross angles based on CFD simulation. The swash-plate cross angle of piston pump affects the piston pump outlet flow pulsation by changing the contraction amount of the plunger in the valve plate transition zone. First, we established the flow pulsation model with swash plate cross angle based on the noise reduction principle of the swash plate cross angle, and studied the influence of cross angle of different rotation angels on the flow pulsation based on CFD simulation. The conclusion is that the maximum and minimum peak of the flow pulsation decreased when the rotation angle of the cross angle is greater than 1 °; the maximum and minimum peak of the flow pulsation increased when the rotation angle of the cross angle is less than -1 °; a good noise reduction can be got when the piston pump cross angle rotates 1°.
Modeling and simulation of a solar flat plate collector as an air heater considering energy efficiency

The present research study includes thermal energy performance analysis of a flat plate solar collector, in order to cover a sensitivity analysis about effective variables contributed to performance increasing approach. To obtain that, energy and momentum governing equations on a flat plate thermal collector were developed to achieve air output temperature and velocity profiles both in model and experiment. The model theory is validated with experiments by a set of flat plate thermal collectors, those located in (35◦ 44′ 35′′ N, 50◦ 57′ 25′′ E) coordinates and then were applied to carry out experimental activities. Quantitative results depicted that the mean difference between predicted and measured output air temperature in natural and forced convection scenarii is 1.47 ◦ C (3.5%) and 0.9 ◦ C (1.5%), respectively; however earlier research works and studies mentioned in literature, include error percentages in the range of 4–10%. Another quantification about, the average error percentages of estimated amounts of output air velocity profile values in natural and forced convection scenarii is 9% and 4%, respectively. This issue realizes the developed model in forced convection scenario more accurate than natural convection scenario.
X-Ray Cargo Inspection: Status and Trends

Over the past several years, x‐ray cargo inspection has experienced tremendous growth. There are several hundred systems in use world wide and a few new units are installed every week. Fielded systems are mostly located in north and West Africa, Middle East, Europe (especially Russia), East Asia, and South America. The majority of systems are powered by Varian M3, M6 or M9 Linac x‐ray sources. The spatial resolution of these systems is typically 3–5 mm, penetration ranges from around 200 mm to 450 mm of steel and contrast sensitivity is typically 1–4%. Inspection throughput ranges from about 20 trucks per hour to 200 trucks per hour. Currently the systems are primarily used to fight import tax evasion and smuggling of controlled substances. There are a few clear trends: Imaging performance has been steadily improving; a variety of systems have been developed to fit different needs; also, there is a strong effort in material discrimination, or even identification and automatic detection. The last, but not .
Finned tube heat exchangers: State of the art for the air side

The findings of various investigators during the past ten years has greatly enhanced our ability to analyze, model, design, and optimize the finned tube heat exchangers so widely used in the HVAC business. The effect of rows, fin pitch, and other geometric parameters are now well understood and generalized heat transfer correlations are available. The relation between heat and mass transfer has been much better defined and good correlations have been developed. Some advances have also been made in modeling techniques especially where partially dry cooling and dehumidifying coils are involved. All of these factors are reviewed to concisely summarize what is now available to the heat exchanger analyst.
Preferences of Freestall Housed Dairy Cows to Different Bedding Materials

ABSTRACT The purpose of this study was to examine the behaviour of dairy cows during the rest periods and their preferences to different bedding materials with limited amount of straw as well as the hygienic score of dairy cows. Thirty-six Holstein dairy cows at the first to fourth lactation with live weight 610±58 kg and milk yield of 7364±1202 liter for 305 days of lactation were used for the experiment. Three types of bedding materials were used for the preference test – rubber mats, manure-straw bedding and sand. The hygienic score of the animal's body was made by 4 point system. The average values of the studied functional activity (FA) were determined by using a mathematical model adapted for this purpose. The installed soft rubber mats on concrete floor mitigated the adverse effects on animal behaviour at rest. The lying time (iFA-0.4133) on the rubber mats and the number of lying down (21.2) during the day showed that rubber mats are more comfortable for cows than manure-straw bedding and sand. When using a small amount of straw bedding, the cows preferred to lie longer on soft rubber mats. The hygienic score of the body of dairy cows was between 1.40 and 2.94, and depended on floor bedding and the regular cleaning of the stall.

Demonstration of HVAC chiller control for power grid frequency regulation—Part 1: Controller development and experimental results

Secondary frequency regulation is a necessary electric grid ancillary service that balances electric power system supply and demand on short time intervals of seconds to minutes. HVAC chillers may be well positioned to provide secondary frequency regulation as a demand side resource. This article describes the experimental development and performance of a practical controller that modifies chiller power demand to provide secondary frequency regulation. Chiller characteristics are identified through testing of a 200-ton (703-kWth) chiller serving a commercial building in Boston. Appropriate control strategies are subsequently determined. Controller demonstrations using standard electric system operator test routines show the chiller power response to exceed qualification requirements while providing up to ±25% of chiller nameplate power in secondary frequency regulation capability. The controller is further demonstrated to provide secondary frequency regulation continuously for several hours, during which building cooling load changes significantly. The companion article (Su and Norford 2015) discussed the experimental results and assesses the applicability of similar chiller control strategies for broader deployment in other buildings.
Corpus Callosum Tractography and its Correlation with Cognitive and Behavioural Changes in Children with Attention-Deficit/Hyperactivity Disorder

Background: Very few studies have investigated the changes in white mater, corpus callosum (CC) specifically, in attention-deficit/hyperactivity disorder (ADHD) patients and its relation to cognitive and behavioral changes in ADHD patients. This study aimed to investigate the correlation between tractography of CC, behavioral and cognitive changes in ADHD patients. Objectives: To detect any morphological changes in corpus callosum in patients with attention-deficit/hyperactivity disorder through diffusion tensor image (tractography) and to elucidate its relation with cognitive and behavioral changes of patients with ADHD. Patients and Methods: A case-control study was done on 100 children divided into two groups; cases and controls at Menoufia University Hospitals. They were selected according to certain inclusion and exclusion criteria. Diffusion tensor imaging (DTI) of CC was done to both groups. Both behavioral and cognitive functions were assessed in correlation with radiological data. Results: There were no significant differences between the groups regarding demographic data that included age and sex, while statistically significant difference (p value <0.001*) was detected in IQ in ADHD (mean IQ was 89.62) compared to control (mean IQ: 96.08). The mean FA value (a measure of white matter consistency in DTI) was higher in control group than in ADHD group in all subdivisions of corpus callosum with no significant difference between the two groups except for the isthmus part (p value 0.034) whose fibers were originating from sensory motor cortex denoting defective functioning in mentioned areas. Conclusion: Diffusion tensor image study of corpus callosum in attention deficit hyperactivity disorder reflected defective inter-hemispheric connectivity mainly sensory motor cortices through isthmus part of corpus callosum.
Electric power quality disturbance detection using wavelet transform analysis

The objective of the paper is to present a novel approach to detect and localize various electric power quality disturbances using wavelet transform analysis. Unlike other approaches where the detection is performed directly in the time domain, detection using wavelet transform analysis approach is carried out in the time-scale domain. As far as detection in power quality disturbance is concerned, one- or two-scale signal decomposition is adequate to discriminate disturbances from their background. This approach is robust in detecting and localizing a wide range of power disturbances such as fast voltage fluctuations, short and long duration voltage variations, and harmonic distortion. <<ETX>>
Survey on modal frequencies of centrifugally stiffened beams

This survey is concerned with the problem of determining the dynamic modal characteristics (natural frequencies and associated mode shapes) of rotating beams. Modal characteristics are of paramount importance to the design and performance evaluation of rotating beams, and have been the subject of interest to many investigators. Accurate prediction of the dynamic characteristics of such structures is necessary in the early stages of the design process in order to avoid any possible conditions susceptible to resonance within the range of operating speed, and to prevent any failure that may occur because of sustained vibration at or near the resonant frequency range. While developing beam models, various parameters pertinent to the functional requirements were added in order to cope with aerodynamic issues as well as technical and economical issues. With all parameters present in the model, solving the problem becomes extremely complicated. An exact solution is almost impossible. Many simplified mathematical models with a variety of geometries and properties have been developed in the literature to investigate the dynamic characteristics of such rotating beams using a variety of methods.
Runtime adaptation in safety-critical automotive systems

The cost-efficient development for dependable systems is one of the major future challenges of the automotive industry. Existing fault tolerance approaches are often not applicable and not sufficient. Therefore, innovative alternatives are required. A possible solution is given by dynamic adaptation. In the case of errors, dynamic adaptation can ensure that the best possible system functionality is achieved and that critical functions are kept alive (survivability). Exploiting implicitly available redundancy, dynamic adaptation provides a cost-efficient means to keep up functionalities as long as possible without requiring expensive explicit redundancy channels. Unconstrained dynamic adaptation can lead to emergent, unpredictable behavior, making it inapplicable for safety-critical systems. In this paper, we illustrate how adaptation behavior can be explicitly modeled, analyzed, and verified at design time. By this means, it is possible to use the advantages of dynamic adaptation for the realization of safe and reliable systems.

Enquiry into the side effects of school inspection in a ‘low-stakes’ inspection context

This article describes a qualitative study into the occurrence of the side effects of school inspection through in-depth interviews in five case schools. The study investigates the extent to which strategic activities, disturbing effects and emotional side effects occur in the case schools. The study also aims to understand features that may explain these side effects. Most research to date has been conducted in England, which is considered a ‘high-stakes’ inspection context whilst ‘low-stakes’ inspection contexts are generally regarded as causing fewer undesirable side effects. This hypothesis, however, is not confirmed by the results of this study. Although the Flemish education context provides a ‘low-stakes’ inspection context, schools in this study engage strongly in strategic activities to produce a better image of the school and school staff members suffer from severe emotional side effects due to the inspection. By contrast, only limited disturbing effects on normal school life were observed. These side effects are affected by principals’ attitude towards the inspection, by schools’ perception of inspectors’ behaviour and by the inspection judgement. The article includes a discussion of the impact on side effects of several particularities of the Flemish education context, such as the absence of central examinations.
Optimal PI and PID Parameters for a Batch of Benchmark Process Models Representative for the Process Industry

This report presents a large number of optimal PI and PID parameters for a batch of 134 benchmark process models representative for the process industry. This information can e.g. be used as a reference for other controller design methods. The optimal parameters have been derived using the MATLAB®-based software called SWORD, which determines the PI or PID controller that gives the best load disturbance performance given some closed-loop robustness. The performance measure used here is the integrated absolute error during a step disturbance on the process input, and the robustness constraints are given by upper limits on maximum sensitivity and complementary sensitivity. It has previously been shown that SWORD can be used to find near-optimal controllers also with respect to an additional noise sensitivity constraint. A controller design method based on this finding gives a set of PI and PID controllers all with the same robustness, but instead with a trade-off between performance and noise sensitivity. Five such sets of controllers are presented here for process models with varying dynamics. There are also a large number of optimal, unfiltered, SWORD PI and PID parameters presented, and related to four different robustness values. All data has been collected in tables which are given at the end of this report. The same tables have been collected in MATLAB® data files, Excel spreadsheets, as well as in a tex-file.
