Understanding piezotronic correlated carrier recombination behavior in quantum wells is essential for their applications. In this work, we have studied the influence of piezotronics on carrier recombination processes in single InGaN/GaN multiple quantum wells microwire (MQW-MW) by using steady-state and time-resolved spectroscopies. We conclude that mechanical strain induced piezotronics promotes

Relatively little has been published about the prevalence of autism in adults with psychiatric disorders. In this study, all new patients referred to an adult psychiatric outpatient clinic in Sweden between November 2019 and October 2020 (n = 562) were screened for autism spectrum disorders using the Ritvo Autism and Asperger Diagnostic Scale Screen (RAADS-14). Out of the 304 (58%) responders, 197

Hydrotropic extraction (HEX) is a method for the delignification of lignocellulose that has been given increasing amounts of attention during the last couple of years. A hydrotrope is an amphiphilic substance, which, in high enough concentrations, can improve solubility of otherwise poorly soluble substances in water. The most commonly used substance for HEX-delignification is sodium xylenesulfona

This paper provides a simplified method of exploring the geographical limits of a knowledge shock over the long run. Using a geographically decomposable distance weighed sum of world GDPs by county, differences in differences regression analysis shows that a new university will not only have a positive impact on the local economy, but also on the GDP of nearby counties. Furthermore, challenging th

Microbial decomposers are responsible for the breakdown of organic matter (OM) and thus regulate soil carbon (C) stocks. During the decomposition of OM, microorganisms can use the assimilated C for biomass production or respire it as CO2, and the fraction of growth to total assimilation defines the microbial carbon-use efficiency (CUE). As such, CUE has direct consequences for how microbial decomp

Vertical InAs/InGaAs nanowire MOSFETs are fabricated in a gate-last fabrication process, which allows gate-lengths down to 25 nm and accurate gate-alignment. These devices demonstrate high performance with transconductance of 2.4 mS/μm, high on-current, and off-current below 1 nA/μm. An in-depth analysis of the heterostructure MOSFETs are obtained by systematically varying th

BACKGROUND: Triage is widely used in the emergency department (ED) in order to identify the patient's level of urgency and often based on the patient's chief complaint and vital signs. Age has been shown to be independently associated with short term mortality following an ED visit. However, the most commonly used ED triage tools do not include age as an independent core variable. The aim of this

Background: To quantify cardiovascular health (CVH), the American Heart Association (AHA) recently launched an updated construct of the “Life's Simple 7” (LS7) score, the “Life's Essential 8” (LE8) score. This study aims to analyse the association between both CVH scores and carotid artery plaques and to compare the predictive capacity of such scores for carotid plaques. Methods: Randomly recruite

School districts in the United States and around the world are increasingly moving away from traditional neighborhood school assignment, in which pupils attend closest schools to their homes. Instead, they allow families to choose from schools within district boundaries. This creates a market with parental demand over publicly-supplied school seats. More frequently than ever, this market for schoo

Technical developments for the detection of formaldehyde using laser-induced fluorescence were presented. A technique for simultaneous detection of formaldehyde and OH using one laser system was presented. The combined formaldehyde and OH technique was applied in laboratory flames and a small spark-ignition engine. The iodine measurement was performed in a cell using the second harmonic of the sin

Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation. The longitudinal movement of art

This report contains an analysis of the process of composing a contemporary twelve-tone piece for big band. I start off by constructing my tone material, presenting the different rows and how they relate to each other. The composition is then finished before finally arranging the piece for big band. I relate my process to the work of Arnold Schoenberg, who is known as the founder of twelve-tone mu

Denna uppsats utreder hur finansiella produkter klassificeras i inkomstslaget kapital, och vilka skatterättsliga skillnader som finns mellan de olika kategorierna i inkomstslaget. Utifrån praxis och inkomstskattelagens systematik redogörs för hur en avyttring av kryptovalutan Bitcoin ska klassificeras och beskattas. Gällande rätt analyseras sedan mot bakgrund av principen om likformighet och skattThis paper examines how financial products are classified within the capital gains bracket and which tax differences follow from such classification. Based on practice and the methodology of the Income tax act, the paper describes how a divestment of the cryptocurrency Bitcoin should be classified and taxed. The result is thereafter analyzed from the perspective of the principle of uniformity and

Sniffing out friends and foes: Bark beetle larvae and fungal scents. A tiny but destructive force is threatening Eurasian forest habitats – the Eurasian spruce bark beetle, Ips typographus. The larvae of this beetle species develop under the bark of conifers and feed on tree tissue. This leads to tree death and thus widespread devastation in wooded landscapes. The beetles live in partnership wit

Finished Goods Distribution Network (FGDN) design is an important aspect of Supply Chain Management (SCM), and companies are constantly working towards balancing cost, service level and product quality in the design. At the same time, sustainability has gained an increased focus by stakeholders which has led to both challenges and opportunities in the logistics industry. The FGDN optimization is e

Rollen av små RNA-molekyler vid omvandlingen av glatta muskelceller Backgrund Blodkärlens viktigaste funktion är att transportera syrerikt blod och näringsämnen till de enskilda organen. Det mellersta lagret i blodkärl består av glatta muskelceller som producerar rikligt med elastiska fibrer. Vid olika typer av kärlskada kan den glatta muskulaturen förlora sin elasticitet och förändra fenotyp vil

Long working hours and burnout as well as other stress-related symptoms are common concerns amongst knowledge workers. An obvious solution might be to reduce working hours, for example, to a 30-hour workweek. Hence, this explorative study is interested in exploring the effects of the 30-hour workweek on knowledge workers. Object of study is a digital marketing agency; eleven semi-structured interv

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
