Long-term performance measurement and analysis of a small-scale ground source heat pump system

Recent data suggest that heat pumps, despite having the potential to cover over 90% of the global space and water heating demands, only provide less than 5% of global heating. Heat pumps, in general, and ground source heat pumps, specifically, offer significant potential for energy savings and carbon emissions reduction in buildings. The realization of these potential benefits, however, requires p

The effects of severe plastic deformation and/or thermal treatment on the mechanical properties of biodegradable mg-alloys

In this study, five MgZnCa alloys with low alloy content and high biocorrosion resistance were investigated during thermomechanical processing. As documented by microhardness and tensile tests, high pressure torsion (HPT)-processing and subsequent heat treatments led to strength increases of up to 250%; as much as about 1/3 of this increase was due to the heat treatment. Microstructural analyses b

Usefulness of High Sensitivity Troponin T to Predict Long-Term Left Ventricular Dysfunction After ST-Elevation Myocardial Infarction

Guidelines recommend the use of transthoracic echocardiography (TTE) and clinical scores to risk stratify patients after ST-elevation myocardial infarction (STEMI). High sensitivity troponin T (hs-cTnT) is predictive of outcome after STEMI but the predictive value of hs-cTnT relative to other risk assessment tools has not been established. We aimed to compare the predictive value of hs-cTnT to oth

Probing the Z = 6 spin-orbit shell gap with (p,2p) quasi-free scattering reactions

The evolution of the traditional nuclear magic numbers away from the valley of stability is an active field of research. Experimental efforts focus on providing key spectroscopic information that will shed light into the structure of exotic nuclei and understanding the driving mechanism behind the shell evolution. In this work, we investigate the Z=6 spin-orbit shell gap towards the neutron dripli

Understanding Library Users via Surveys and Other Methods—Best Practices for Evidence-Based Library Development

A survey was performed over all university libraries within the Association of European Research Libraries (LIBER) in order to study how different methods of user input are utilized. Libraries using analysis based on explorative methods - such as UX and process mapping - report significantly increased user knowledge and perceived well-function.

COVID-19 : guidance on palliative care from a European Respiratory Society international task force

Background: Many people are dying from coronavirus disease 2019 (COVID-19), but consensus guidance on palliative care in COVID-19 is lacking. This new life-threatening disease has put healthcare systems under pressure, with the increased need of palliative care provided to many patients by clinicians who have limited prior experience in this field. Therefore, we aimed to make consensus recommendat

Metastable precursor structures in hydrogen-infused super duplex stainless steel microstructure – An operando diffraction experiment

We report the evolution of metastable precursor structures during hydrogen infusion in the near-surface region of a super duplex stainless steel. Grazing-incidence x-ray diffraction was employed to monitor, operando, the lattice degradation of the austenite and ferrite phases. Electrochemical hydrogen charging resulted in the splitting of the diffraction peaks of the austenite phase, suggesting th

Semi-analytical flash temperature model for thermoplastic polymer spur gears with consideration of linear thermo-mechanical material characteristics

The temperature increase that occurs during running of a polymer gear pair can be divided into two components: the nominal and flash temperatures. The latter denotes the short-term temperature increase that takes place during a gear meshing cycle. A thorough analysis of the flash temperature yields an insight into the heat dissipation process, which also determines the nominal temperature increase

The Digital Architectures of Social Media : Comparing Political Campaigning on Facebook, Twitter, Instagram, and Snapchat in the 2016 U.S. Election

The present study argues that political communication on social media is mediated by a platform’s digital architecture—the technical protocols that enable, constrain, and shape user behavior in a virtual space. A framework for understanding digital architectures is introduced, and four platforms (Facebook, Twitter, Instagram, and Snapchat) are compared along the typology. Using the 2016 U.S. elect

Scandalous Design : How Social Media Platforms’ Responses to Scandal Impacts Campaigns and Elections

Given the role of social media in the modern election, scholars should not only study how platforms function for political actors; we should also study how platforms function as political actors. This essay therefore introduces the concept of scandalous design, which refers to programmatic changes in how social media operate in response to scandal. On the one hand, scandals can encourage changes i

Host-plant availability drives the spatiotemporal dynamics of interacting metapopulations across a fragmented landscape

The dynamics of ecological communities depend partly on species interactions within and among trophic levels. Experimental work has demonstrated the impact of species interactions on the species involved, but it remains unclear whether these effects can also be detected in long-term time series across heterogeneous landscapes. We analyzed a 19-year time series of patch occupancy by the Glanville f

Recycling of ash from co-incineration of waste wood and forest fuels: An overlooked challenge in a circular bioenergy system

Wood ash recycling to forests after logging residues harvest is important to ensure long-term sustainable forest management, however, it is not recycled in Sweden at the level required to compensate for current logging residue out-take. A problem in this context is wood ash contamination through co-incineration of waste wood with forest fuels, a practice driven by the political goal of a circular

Paul’s Argumentation in Galatians : A Pragma-Dialectical Analysis

Galatians is a polemical letter which contains a substantial amount of argumentative passages. Paul evidently wanted to persuade by using the best arguments possible to convince his addressees. Using a state-of-the-art method from the discipline of argumentation analysis, Paul's argumentation can be analysed with a precision that standard exegetical methods cannot provide.

Towards a Comprehensive Analysis of Paul’s Argumentation

"One aspect rarely addressed in rhetorical analyses of Pauline texts is that the emphasis on rhetorical features tends to exclude dialectical aspects such as the layout of arguments and their soundness. However, these are equally important aspects alongside the rhetorical ones when assessing argumentation from an overall perspective." s. 209One aspect rarely addressed in rhetorical analyses of Pauline texts is that the emphasis on rhetorical features tends to exclude dialectical aspects such as the layout of arguments and their soundness.

Kalevalaseuran Kekrin päivän Puheen juhla tarjosi harvinaisen retorisen herkun:kaksitoista Suomen historian kiinnostavaa puhetta, vuodesta 1809 alkaen nykyhetkeen saakka. Nälkäteatterin esittämät historialliset puheet herättivät historian eloon, joskin retorista hetkeä – kairosta – on mahdotonta luoda uudelleen. Hyvällä mielikuvituksella pystyi kuitenkin kuvittelemaan olevansa mukana muun muassa P

"Suomalaista puhekulttuuria pidetään usein vaatimattomana. Yksi tällaisen puhekulttuurin tunnetuimmista ilmentymistä on Aki Kaurismäen niin kutsuttu työläistrilogia.
