En termoelektrisk komponent utnyttjar den termoelektriska effekten till att omvandla värme till elektricitet. Termopar (eng: thermocouple) är en variant av termoelektriska komponenter. Termopar består av två parallellt liggandes elektriska ledare med ändarna anslutna till en kall och en varm källa. Storleken av ett termopar kan göras nanometer stora om man använder nanotrådar som elektriska ledareIn this project the transport phenomenon Coulomb drag is studied in a 1D system comprised of two nanowires in parallel. Specifically, a driving current across the active wire generated a drag current in the passive wire, and we studied how Coulomb drag influenced both the driving and drag currents. The theoretical calculations used in this project are based on the approach made by Gurevich et al.

Den klimatpåverkan, resursförbrukning och avfallsgenerering som byggbranschen står för idag är omfattande, till exempel står sektorn för 25–35 % av Europas avfall. Det råder en situation där resurseffektiviteten är låg och värdet av de råvaror som används inte tillvaratas. Förbrukningen av naturresurser är stor och möjligheterna att begränsa detta genom återbruk, där både resurser och inbyggd enerThe building industry is responsible for a substantial climate impact, resource consumption and waste generation. As an example, the sector produces 25-35 % of all the waste in Europe. Currently, the resource value is not captured as the resource efficiency is low. The consumption of natural resources is extensive and the opportunity to limit this through reuse, where both resources and the embodi

Sedan år 2000 har 52% av företagen på Fortune-500 gått i konkurs på grund av bland annat ökad konkurrens och nya krav från kunder. Detta ställer större krav på hur företag arbetar med innovation som sägs vara en av de viktigaste faktorerna för företags framtida överlevnad. Dock visar det sig att omsätta teorin i praktiken är utmanande och inom forskningen saknas en enhetlig definition om vad innovThe average life expectancy for large companies on the fortune 500 list has declined rapidly since the 1950s. One major reason is the growing competition from new actors on the market. Innovation has become one of the most important competencies for companies to get ahead of the competition. The growing demand for companies to be innovative and at the same time operate their core business have dee

Det Svenska flerbostadshusbeståndet från åren 1945-1975 är på väg att nå slutet på sin tekniska livslängd. Byggnaderna från denna tidsperiod är i stort behov av renovering samt energieffektiviserande åtgärder för att minska energianvändningen och möjliggöra fortsatt användning av byggnaderna i framtiden, samtidigt som ekonomiskt utsatta personer har råd att bo kvar i byggnaderna. Dagens utmaning äThe Swedish apartment building stock from 1945-1975 is reaching the end of its technical life span. Renovations and energy efficiency measures are needed to reduce energy use and enable continued usage of the buildings in the future and still provide affordable housing to socioeconomic vulnerable groups. The problem today is that some building features, which are needed to estimate the renovation

Characterizing ore deposits or mining dumps in terms of mineral content and grain size remains a challenge. Since the 1950s the induced polarization (IP) method has been successfully applied in ore prospecting. However, reliably interpreting field survey data requires comprehensive laboratory studies to establish a link between the IP parameters from empirical or phenomenological models and the typ

Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote

Mätning av relativ fuktighet, RF, i betong har tagit ett stort steg framåt med hjälp av trådlösa RF-prober som kan gjutas in direkt från start. I ett nyligen avslutat projekt vid avdelning Byggnadsmaterial vid Lunds tekniska högskola har ett mätsystem för RF i betong utvärderats. En av de största utmaningarna var att säkerställa att proberna klarar ingjutning och att de ger tillförlitliga mätninga

Bostadskrisen slår mot alla generationer – men lösningarna måste vara långsiktiga och inkludera de behov äldre människor har. Det skriver fyra forskare som är verksamma vid institutionen för hälsovetenskaper vid Lunds universitet och tillhörforskningscentret CASE, Centre for Ageing and Supportive Environments.

Pre-rain green-up is a distinctive phenological phenomenon observed in arid and semi-arid regions, featuring the sprouting of plants before the onset of the rainy season. This phenomenon indicates the intricate controls of vegetation phenology other than precipitation, yet its global distribution patterns and underlying causes remain unclear. In this study, we used remotely sensed phenology and ra

Background. The role of primary healthcare (PHC) during a pandemic varies across European countries. The coronavirus disease 2019 (COVID-19) pandemic has altered the working practices of family medicine doctors and impacted the resilience of healthcare systems. Objectives. This study aimed to examine European healthcare system responses to the pandemic, focusing on rural and urban differences. Mat

Aims Alternative splicing of Titin (TTN) I-band exons produce protein isoforms with variable size and elasticity, but the mechanisms whereby TTN splice factors regulate exon usage and thereby determining cardiomyocyte passive stiffness and diastolic function, is not well understood. Non-coding RNA transcripts from the antisense strand of protein-coding genes have been shown to regulate alternative

Forward-only algorithms offer a promising memory-efficient alternative to Backpropagation (BP) for on-device training. However, state-of-the-art forward-only algorithms, e.g., Forward-Forward (FF), still require a substantial amount of memory during the training process, often exceeding the limits of mobile edge and Internet of Things (IoT) devices. At the same time, existing memory-optimization t

Despite the crucial role of various insulin analogs in achieving satisfactory glycemic control, a comprehensive understanding of their in-solution dynamic mechanisms still holds the potential to further optimize rapid insulin analogs, thus significantly improving the well-being of individuals with Type 1 Diabetes. Here, we employed hydrogen-deuterium exchange mass spectrometry to decipher the mole

Marknadsföring är så mycket mer än strategier, marknadsundersökningar och reklamkampanjer. Den uppstår i det dagliga samspelet mellan människor. I Marknadsföring, människor och interaktion får vi ett alternativt perspektiv på marknadsföring, bortom den traditionella marketing management-logiken. Genom att utgå från symbolisk interaktionism synliggör författarna hur marknader, konsumenter, produkte

We present the artillery of a well-preserved late medieval Danish-Norwegian carvel warship, Gribshunden. Probably built in the Netherlands in 1484, the ship served King Hans until sinking in June 1495. Of its original 50 or more guns, elements of 11 have been recovered and digitally recreated, and more remain on the wreck. Investigation of this site provides insights into the development of shipboWe present the artillery of a well-preserved late medieval Danish-Norwegian carvel warship, Gribshunden.

Pulmonary arterial hypertension (PAH) is a heterogenic diagnosis including idiopathic and hereditary PAH (IPAH/HPAH) and groups associated to connective tissue disease (APAH-CTD) and congenital heart disease (APAH-CHD). Pre- and post-diagnosis societal costs in PAH subgroups are not well known. By linking Swedish national databases, societal costs in a national PAH cohort 5 years before and 5 year
