A parenting education program for women in treatment for opioid-use disorder at an outpatient medical practice
No full text© 2017 Taylor & Francis. Opioid use during pregnancy poses serious risks for the mother and the unborn child. Opioid-use disorder may be managed with medication-assisted treatment (MAT) in an outpatient setting, but few MAT practices specifically address the challenges faced by pregnant women. This article describes a medical office-based educational support group for women in MAT for opioid-use disorder who were pregnant and/or parenting young children. Focus groups were conducted to elicit patient feedback. Women indicated that they found the educational support groups beneficial and offered suggestions. In-office educational support groups for pregnant women in treatment for opioid-use disorder are feasible and well received
Meditation Awareness Training (MAT) for work-related wellbeing and job performance: a randomised controlled trial
No full textDue to its potential to concurrently improve work-related wellbeing (WRW) and job performance, occupational stakeholders are becoming increasingly interested in the applications of meditation. The present study conducted the first randomized controlled trial to assess the effects of meditation on outcomes relating to both WRW and job performance. Office-based middle-hierarchy managers (n = 152) received an eight-week meditation intervention (Meditation Awareness Training; MAT) or an active control intervention. MAT participants demonstrated significant and sustainable improvements (with strong effect sizes) over control-group participants in levels of work-related stress, job satisfaction, psychological distress, and employer-rated job performance. There are a number of novel implications: (i) meditation can effectuate a perceptual shift in how employees experience their work and psychological environment and may thus constitute a cost-effective WRW intervention, (ii) meditation-based (i.e., present-moment-focussed) working styles may be more effective than goal-based (i.e., future-orientated) working styles, and (iii) meditation may reduce the separation made by employees between their own interests and those of the organizations they work for

Applying the method of fundamental solutions to harmonic problems with singular boundary conditions
No full textThe method of fundamental solutions (MFS) is known to produce highly accurate numerical results for elliptic boundary value problems (BVP) with smooth boundary conditions, posed in analytic domains. However, due to the analyticity of the shape
functions in its approximation basis, theMFS is usually disregarded when the boundary functions possess singularities. In this work we present a modification of the classical MFS which can be applied for the numerical solution of the Laplace BVP with Dirichlet boundary conditions exhibiting jump discontinuities. In particular, a set of harmonic functions with discontinuous boundary traces is added to the MFS basis. The accuracy of the proposed method is compared with the results form the classical MFS.The financial support from Center for Computational and Stochastic Mathematics (CEMAT–IST) through Fundac¸ ˜ao para a Ciˆencia e a Tecnologia (FCT) projects PEst-OE/MAT/UI0822/2014 and EXCL/MAT-NAN/0114/2012 is gratefully acknowledged
A novel concept for the specific detection of circulating cells based on heat flow through surface-imprinted polymer layers
No full textNovel detection platforms for the identification of disease-related cells in patient samples are of enormous interest for the medical community. These platforms could also be useful in environmental and food safety by monitoring the amount of pathogens in drinking water and/or food. Current state-of-the-art cell detection platforms are very sensitive and specific but these techniques are typically very expensive, complicated and require analysis by a professional in a lab environment. Biosensors could offer a fast, low-cost and user-friendly alternative for these platforms. However, biosensors usually make use of biological receptors such as antibodies or enzymes for the detection of biological compounds. While these natural receptors are very selective and sensitive, they have the drawback of being instable and expensive. Molecularly imprinted polymers (MIPs) are a classic alternative for these natural receptors but due to the size of the target cells, MIPs produced by classical imprinting techniques are not suitable for the detection of these compounds. Therefore, a novel approach was tested, creating synthetic receptors by surface imprinting of thin polyurethane layers. For the sake of simplicity these surface imprinted polymers will be referred to as SIPs from hereon. ..

The proposed goodyear modular mat type scrap tire floating breakwater
No full textScrap tires are proposed as a construction material for building large floating mat type breakwater devices. The Goodyear scrap tire floating breakwater assemblies are formed by securing together modular bundles of tightly interlocked scrap tires with high strength rope/cable, or special corrosion resistant steel rods. This construction procedure yields an easily installed, readily adaptable breakwater structure which has high energy absorbing capacity for normal loading conditions but which deforms and yields when subjected to overloads. The proposed designs rely on a modular bundle concept where a relatively few tires are secured together to form a small easily assemble de portable building unit which,serves as a basic building block from which giant breakwater devices can be constructed. Flotation is provided by placing a small amount of buoyant material in the crown of each tire or by filling approximately 10%) of the tires with buoyant foam. The design possibilities using scrap tire building modules are virtually limiless. Tires may be laced together to form large flat single or multiple thickness shallow mats. They may be stacked vertically in single or multiple thickness bundles like bricks in a wall to form curtain type barriers. Variutions in breakwater draft are made possible by adding modules above or below to vary the thickness and by combining constructions such as hanging a curtain on a mat structure. Also, mats with varying buoyancy may be moored on an incline for more efficient energy absorption
Application of MAT device to characterize the adhesive bonding strength of membrane in orthotropic steel deck bridges
No full textIn order to characterize adequately the adhesive bonding strength of the various membranes with surrounding materials on orthotropic steel decks and collect the necessary parameters for FE modeling, details of the Membrane Adhesion Test (MAT) have been introduced. Analytical constitutive relations of MAT device have been derived on the basis of Williams (1997). Furthermore, on the basis of experimental data obtained from MAT, ranking of the bonding characteristics of various membrane products is demonstrated as well as the role of other influencing factors, such as the types of substrate and test temperatures.Structural EngineeringCivil Engineering and Geoscience
Tail dependence under sample failures
No full textWhen collecting samples, sometimes failures of observations occur and consequently missing data. This can have an impact on the analysis and subsequent inference, especially if the study focuses on the extreme values where the data is more scarce. In this work, we analyze the effect of different types of failures on the dependence within the tail of a stationary series. We will also present some examples.The first author was supported by Portuguese Funds through FCT — Fundação para a Ciência e a Tecnologia within the Projects UID/MAT/00013/2013 of Centre of Mathematics of the University of Minho, UID/Multi/04621/2019 of Center for Computational and Stochastic Mathematics, UID/MAT/00006/2019 of Centre of Statistics and Its Applications, and PTDC/MAT-STA/28243/2017.
