A Smartphone App to Promote Healthy Weight Gain, Diet, and Physical Activity During Pregnancy (HealthyMoms): Protocol for a Randomized Controlled Trial
Background: Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long
term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known
about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy.
Objective: The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms)
for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on
dietary habits, physical activity, body fatness, and glycemia during pregnancy.
Methods: HealthyMoms is a two-arm randomized controlled trial. Women are being recruited at routine visits at the maternity
clinics in Linköping, Norrköping and Motala, Sweden. Women are randomized to the control or intervention group (n=150 per
group). All women will receive standard care, and women in the intervention group will also receive the HealthyMoms smartphone
app.
Results: Recruitment of participants to the trial was initiated in October 2017, and 190 women have so far completed the baseline
measurement. The baseline measures are estimated to be finalized in December 2019, and the follow-up measures are estimated
to be completed in June 2020. Conclusions: This project will evaluate a novel smartphone app intervention integrated with existing maternity health care. If
successful, it has great potential to be implemented nationally in order to promote healthy weight gain and health behaviors during
pregnancy
Direct intramyocardial plasmid vascular endothelial growth factor-A165gene therapy in patients with stable severe angina pectoris A randomized double-blind placebo-controlled study: The Euroinject One trial
ObjectivesIn the Euroinject One phase II randomized double-blind trial, therapeutic angiogenesis of percutaneous intramyocardial plasmid gene transfer of vascular endothelial growth factor (phVEGF-A165) on myocardial perfusion, left ventricular function, and clinical symptoms was assessed.BackgroundEvidence for safety and treatment efficacy have been presented in phase I therapeutic angiogenesis trials.MethodsEighty âno-optionâ patients with severe stable ischemic heart disease, Canadian Cardiovascular Society functional class 3 to 4, were assigned randomly to receive, via the NOGA-MyoStar system (Cordis Corp., Miami Lakes, Florida), either 0.5 mg of phVEGF-A165(n = 40) or placebo plasmid (n = 40) in the myocardial region showing stress-induced myocardial perfusion defects on 99mTc sestamibi/tetrofosmin single-photon emission computed tomography.ResultsNo differences among the groups were recorded at baseline with respect to clinical, perfusion, and wall motion characteristics. After three months, myocardial stress perfusion defects did not differ significantly between the VEGF gene transfer and placebo groups (38 ± 3% and 44 ± 2%, respectively). Similarly, semiquantitative analysis of the change in perfusion in the treated region of interest did not differ significantly between the two groups. Compared with placebo, VEGF gene transfer improved the local wall motion disturbances, assessed both by NOGA (p = 0.04) and contrast ventriculography (p = 0.03). Canadian Cardiovascular Society functional class classification of angina pectoris improved significantly in both groups but without difference between the groups. No phVEGF-A165-related adverse events were observed; however, NOGA procedure-related adverse events occurred in five patients.ConclusionsThe VEGF gene transfer did not significantly improve stress-induced myocardial perfusion abnormalities compared with placebo; however, improved regional wall motion, as assessed both by NOGA and by ventriculography, may indicate a favorable anti-ischemic effect. This result should encourage more studies within the field. Transient VEGF overexpression seems to be safe

Synthetic nacre : Produced by in situ crystallisation
This thesis describes a sequence of experiments which have been performed with the intention to produce synthetic nacre. Synthetic nacre is a biomimetic material based on nacre, a material which can be found in mollusc shells. Nacre is a nanocomposite which has improved mechanical properties compared to the principal component aragonite (95% wt%). The improved properties of nacre are derived from the polymeric components in the composite which allows from redistribution of forces under load. Carbonates sequester CO2 in the geological CO2-cycle. If precursor are sourced correctly, the CaCO3 in synthetic nacre can temporarily sequester CO2. Crystals with the intended pseudohexagonal morphology have been synthesised. However, subsequent quantitative analysis could not support these findings in a follow-up experiment. This discrepancy might have been caused by differences in the method. Moist nanopaper was found to be mineralisable while maintaining a layered structure

Fibrer frÄn Rensenor : Mekaniska processer och rötningsprocesser för att extrahera kollagenfibrer
Collagen fibres from reindeer tendons can be used to create threads. These threads have traditionally been used in SĂĄpmi crafts. Due to the high cost of manual extraction, tendon-based threads have been replaced with cheaper synthetic threads. However environmental concerns have been raised within the SĂĄpmi crafts communities regarding the synthetic threads. To mitigate the impacts of synthetic threads and to better utilize the reindeer after slaughter a more efficient fibre extraction process has been sought after. In this study two venues have been investigated, softening and retting. In this study softening will refer to the breaking of bonds through the use of a liquid. Retting will refer to a controlled degradation of a material through biological processes. Softening and retting aided mechanical extraction of collagen fibres. The softening, using water and in some cases polyethylene glycol, reduced entanglement and friction. The retting can be divided into short term retting and long-term retting, up to six weeks. Neither the short-term retting nor the long-term retting did facilitate the extraction significantly compared to a simpler softening treatment. Softening on the other hand made extraction easier. A 70 hour softening with water at room temperature had the largest impact. The extraction became slightly easier when the samples were further softened with polyethylene glycol. This was compared to a reference sample where water was used for further softening. Mechanical fibre extraction methods were also evaluated. The softened tendon samples were calendered between two rollers at 1.2 bar and 5.0 bar. The samples using the higher pressure were easier to separate. The samples were then manually torn apart into fine fibre bundles. Many of the manual methods used can be automated but they would need specialized equipment. The mechanically extracted fibres were then spun into yarns through hand spinning with moistened fingers. The tensile properties of the fibres and the yarns were determined. The fibres and the yarns were also evaluated through light microscopy. Both the yarns and fibres showed a high degree of variation in the tensile tests. The use of manual methods likely contributed to the high variation. The yarns slipped which caused a lower tenacity compared to the fibres. The mean fibre tenacities were between 17-20 cN/tex, depending on factor. Neither of the factors were significantly different. The elasticity of the fibres varied to a large extent. The fibres exhibited an almost fully elastic deformation until break. The fibres were white to cream and slightly translucent when viewed in a light microscope. The yarns were uneven and glossy
Utmaningar vid implementering av RoboticProcess Automation : En studie om vilka utmaningar som RPA-leverantörerkan stÀllas inför vid implementering av RPA
Organisationer blir allt mer beroende av digitala lösningar i den dagliga verksamheten för att upprĂ€tthĂ„lla konkurrensen gentemot andra företag. Under en lĂ€ngre tid har organisationer implementerat Enterprise Resource Planning (ERP) system för att effektivisera verksamheterna och öka konkurrensfördelarna. I takt med utvecklingen av digitala lösningar har begreppet Robotic Process Automation (RPA) vĂ€xt fram. RPA implementeras för att automatisera och effektivisera organisationers affĂ€rsprocesser. Likt implementering av ERP-system finns det utmaningar kopplade till implementering av RPA som behöver hanteras för att minska kostnader och öka effektiviteten. Tidigare forskning som identifierats har undersökt utmaningar vid implementering av RPA utifrĂ„n kundens och projektets perspektiv. DĂ€remot har tidigare forskning som identifierats inte undersökt eller behandlat utmaningar utifrĂ„n RPA-leverantörens perspektiv, vilket resulterade i studiens syfte och undersökningsomrĂ„de. Syftet med studien Ă€r att undersöka och kartlĂ€gga utmaningar som RPA-leverantörer kan stĂ€llas inför vid implementering av RPA. För att besvara frĂ„gestĂ€llningen och erhĂ„lla en djupare förstĂ„else kring undersökningsomrĂ„det har nio RPA-konsulter intervjuats. Studiens resultat pĂ„visar att kartlagda utmaningar utifrĂ„n RPA-leverantörens perspektiv vid implementering av RPA bĂ„de skiljer sig och överensstĂ€mmer med utmaningar som identifierats i litteraturstudien utifrĂ„n projektets och kundens perspektiv. I slutsatsen presenteras elva utmaningar som RPA-leverantörer kan stĂ€llas inför vid implementering av RPA. Organizations are becoming more dependent on using digital solutions in their daily operations to stay competetive with other companies. Organizations have implemented Enterprise Resource Planning (ERP) systems for a long time to streamline operations and increase competitive advantages. Along with the development of digital solutions, the concept of Robotic Process Automation (RPA) has developed. RPA is implemented to automate and streamline the organization's business processes. As an implementation of ERP systems, there are challenges associated with the RPA implementation that must be addressed to reduce costs and increase efficiency. Previous research that has been identified has investigated challenges with implementing RPA from a customer and project perspective. However, previous identified research has not investigated or mapped the challenges from the perspective of the RPA supplier, which resulted in the study's purpose and area of ââstudy. The purpose of the study is to investigate and map the challenges that RPA suppliers may face when implementing RPA. To answer the question of the study and gain a deeper understanding of the study area, nine RPA consultants were interviewed. The result from the study demonstrates that mapped challenges from the RPA supplier perspective both differ and confirm challenges identified in previous research from a customer and project perspective. The conclusion presents eleven challenges that RPA suppliers may face when implementing RPA
Fallstudie i politiskt anvÀndarbeteende pÄ Wikipedia
Wikipedia has since its inception in 2001 become the worldâs largest encyclopedia and continues to enjoy a high degree of support from the general public. This report investigate differences in the user creation process of content between political and unpolitical articles. According to the results the revisions per user follow a similar pyramid pattern in both the political and unpolitical articles. When investigating the number of reverts the results differ between the political and unpolitical articles. More reverts are made by semi active users in the political articles.  The report also establish that some political categories exhibit a significantly longer edit history than the Wikipedia average and that these categories contain a disproportionately high number of reverts among their revisions.  Conclusions are that there are differences between political and unpolitical articles in regard to who do reverts and the number of reverts per page.Wikipedia har sedan det skapades 2001 blivit vĂ€rldens största encyclopedia och den fortsĂ€tter erhĂ„lla en hög grad av stöd och tillit frĂ„n allmĂ€nheten. Denna rapport undersöker skillnader i anvĂ€ndarbeteende under skapande processen av innehĂ„ll för politiska och opolitiska artiklar. Det framkom att politiska artiklar uppvisar en liknande pyramid struktur som opolitiska i hĂ€nseende till antalet revisioner per anvĂ€ndare men att de skiljer sig i hĂ€nseende till reverts, som till en högre grad utförs av mellan-aktiva anvĂ€ndare i politiska artiklar. Rapporten tar Ă€ven och visar att vissa politiska kategorier har lĂ€ngre editeringshistorier Ă€n Wikipedias genomsnitt och dessa kategorier innehĂ„ller en oproportionerligt hög andel reverts bland sina revisioner. Slutsatser Ă€r att det finns skillnader mellan politiska och opolitiska artiklar i hĂ€nseende till vem som gör reverts och antalet reverts per sida
Conversion of rental apartments to condominiums : A study of necessary adjustments for an optimal conversion
Det frĂ€msta motivet regeringen hade för införandet av Ă€garlĂ€genheter Ă„r 2008 var att skapa valfrihetoch mĂ„ngfald pĂ„ bostadsmarknaden. Antalet Ă€garlĂ€genheter har ökat successivt, dĂ€remot har det intebyggts lika mĂ„nga Ă€garlĂ€genheter som regeringen prognostiserat. Om omvandling blir en möjlighetskulle andelen Ă€garlĂ€genheter öka pĂ„ marknaden. Detta examensarbete har i syfte att undersöka omdet finns anpassningar som behöver göras i befintliga hyreshus vid en omvandling för att hyresrĂ€tterska övergĂ„ till lĂ€mpliga Ă€garlĂ€genheter. Dessutom ska detta arbete utreda om dessa anpassningar Ă€rsvĂ„ra att genomföra. I detta examensarbete har en kvalitativ metod anvĂ€nts genom en intervjustudie för att ge en djupareförstĂ„else för Ă€mnet. Intervjuerna har genomförts med olika experter inom Ă€mnesomrĂ„det och bestĂ„rav fastighetsbolag, förrĂ€ttningslantmĂ€tare och sakkunniga. Dessutom har en litteraturstudiegenomförts dĂ€r propositioner, kommittĂ©direktiv och statliga offentliga utredningar analyserats för attfĂ„ en grundlĂ€ggande förstĂ„else för de bakomliggande motiven för införandet av Ă€garlĂ€genheter. Studien visar att det finns bĂ„de fastighetsrĂ€ttsliga och byggtekniska anpassningar som behöver görasvid en omvandling av hyresrĂ€tter till Ă€garlĂ€genheter. Dessa Ă€r att skapa nya fastighetsgrĂ€nser, bildagemensamhetsanlĂ€ggningar och hantera byggtekniska skillnader mellan respektive upplĂ„telseform.Anpassningar som berör gemensamhetsanlĂ€ggningar och byggtekniska skillnader Ă€r inte ett krav föratt omvandling ska vara möjligt, men Ă€r nödvĂ€ndiga att genomföra för att bilda lĂ€mpligaĂ€garlĂ€genheter. Dock framkommer det att omvandling av Ă€ldre fastigheter kan vara problematiskteftersom att det finns risk att vĂ€sentlig information antingen inte stĂ€mmer eller saknas helt. Ă
sikterna för en möjlighet till omvandling varierar mellan olika aktörer. DÀremot tror mÄnga att det iframtiden kan bli en möjlighet att omvandla hyresrÀtter till ÀgarlÀgenheter. Den viktigasteförutsÀttningen för en omvandling Àr att regeringen skapar en fungerande lagstiftning med starktkonsumentskydd och fungerande förvaltning.The main motive behind the government's introduction of condominium apartments in 2008 was tocreate options and diversity in the housing market. The number of condominium apartments hasgradually increased, however, the amount has not met the government's forecasts. If conversionbecomes an option, the proportion of condominium apartments on the market would increase. Thisthesis aims to investigate whether there are adjustments that need to be made in existing rentalproperties to convert rental apartments into suitable condominium apartments. Additionally, this workwill examine whether these adjustments are difficult to implement. In this thesis, a qualitative method has been used through an interview study to provide a deeperunderstanding of the subject. The interviews were conducted with various experts in the field,including real estate companies, surveyors, and specialists. Furthermore, a literature study wasconducted, analyzing bills and public inquiries to gain a fundamental understanding of the underlyingmotives for the introduction of condominium apartments. The study shows that there are both judicial adjustments and building technical adjustments that needto be made when converting rental apartments into condominium apartments. These include creatingnew property boundaries, establishing joint facilities, and handling building technical differencesbetween the respective forms of tenure. Adjustments concerning joint facilities and building technicaldifferences are not required in order for the conversion to be possible, but they are necessary to createsuitable condominium units. It is noted, however, that the conversion of older properties can beproblematic due to the risk that essential information may either be incorrect or entirely missing. Opinions on the possibility of conversion vary among different concerned parties. However, manybelieve that in the future, it may be possible to convert rental apartments into condominiumapartments. The most important condition for a successful conversion is that the government createseffective legislation with strong consumer protection and efficient management
