We study experimentally and with wave optics modelling the absorption of light in CsPbBr3perovskite nanowire arrays fabricated into periodic pores of an anodized aluminum oxide matrix, for nanowire diameters from 30 to 360 nm. First, we find that all the light that couples into the array can be absorbed by the nanowires at sufficient nanowire length. This behavior is in strong contrast to the expe

Popular Abstract in Swedish Ett biologiskt samhälle definieras av de arter som lever och interagerar på en plats. Platsen kan vara en sjö, en ö eller ett skogsparti. Om det dessutom finns flera platser som arter sprider sig mellan brukar man tala om ett metasamhälle. Idag vet man att både ekologiska och evolutionära processer påverkar metasamhällens uppbyggnad, stabilitet och funktionalitet. DenThis thesis aims to elucidate the link between abiotic and biotic effects and biogeographical contingencies, eco-evolutionary assembly processes, and community structure in a spatially explicit metacommunity framework. To this end, we used structure analysis of naturally sampled and experimentally manipulated marine bacterial communities and mathematical eco-evolutionary modeling and simulations o

Objective: To assess whether adding prostate volume to the kallikrein panel improves discrimination for ISUP Grade Group 2 or higher (GG2+) disease, as some men may have volume measurements available at the time of blood draw. While prostate volume predicts biopsy outcome, it requires an imaging procedure for measurement. The four kallikrein panel - commercially available as the 4Kscore - predicts

Soil microorganisms play an integral role in the regulation of carbon (C) cycling. In high-latitude ecosystems, climate warming is leading to higher plant productivity, shrub expansion and faster nutrient cycling; all of which increase resource availability to soil microorganisms. To understand how a legacy of enhanced resource availability affects the functional traits of microbial communities, a

Background: While housing and neighborhood features have the potential to impact opportunities for active aging, there is a lack of knowledge related to how older people reason regarding their housing situation and how housing and fulfillment of relocation are associated with active and healthy aging. Objective: The objectives of Prospective RELOC-AGE are to study housing choices and relocation an

Purpose: The Extremely Preterm Infants in Sweden Study (EXPRESS) followed a national cohort of extremely preterm born (EPT, i.e. <27 weeks) children until 12 years of age. This study aimed to investigate the longitudinal development of visual acuity (VA) in children born EPT, explore the predictive value of early visual assessments, and evaluate risk factors for visual impairment at the age of 12

IT ses ofta som en del av lösningen för att uppnå ett hållbart samhälle genom till exempel minskat resande, optimering av industri- och jordbruksprocesser, intelligenta elmätare och smarta hem. Något man sällan reflekterar över är att ITbranschen själv också bidrar till elanvändningen. Ett nytt fenomen inom IT-världen är molnet som ger möjlighet till som det verkar outtömliga resurser i form av laInformation and communication technology (ICT) is often seen as part of the solution for a sustainable society, for example through reduced travel, optimization of industrial and agricultural processes, smart meters and smart homes. However, something usually left unconsidered is the electricity consumption of ICT itself. A new phenomenon of the ICT industry is the Cloud that enables seemingly ine

Inte hur förpackningen påverkar din mat, utan hur din mat påverkar förpackningen. Resultatet av detta arbete kan komma att ligga till grund för miljövänligare förpackningar som ger maten längre hållbarhet och förbättrar möjligheterna för att transportera mat över hela världen. Tetra Pak har länge arbetat med att leverera ett smartare och miljövänligare sätt att förpacka mat med sina pappförpackniTetra Pak delivers food packing services world-wide and uses multilayer packaging materials to protect the food product from being affected by the environment. Loss of adhesion between the polymer and the aluminium layer in Tetra Paks packaging materials has proven to be a serious problem casing the package to lose its integrity and the food product to spoil. The problem is relatively unstudied bu

It seems that people are more disconnected to the objects they own than ever before. What has changed in the last decades? People had tools and the skills to use them, but due to convenience and easy consumable entertainment, do-it-yourself was replaced by do-it-forme. Tasks we would have handled ourselves in the past are now done by a product or a service. This is disabling people. By losing ski

I takt med den tekniska utvecklingen behandlas personuppgifter i allt större utsträckning och mer gränsöverskridande. Behandling och överföring av personuppgifter är förenat med en risk för att individens integritetsskydd åsidosätts. EU har en stark dataskyddslagstiftning och värnar om skydd av EU-medborgares personuppgifter. USA har inte en lika stark dataskyddslagstiftning. Samtidigt är USA enWith the fast development in information technology, personal data is increasingly being processed and interchanged cross-border. Processing and transfer of personal data is associated with a risk that the individual's privacy protection is disregarded. The EU has strong data protection legislations and a strong protection of the personal data of EU citizens. The U.S. does not have as strong

This thesis explores how Swedish civil society organisations (CSOs) navigate transnational partnerships under civic space restrictions in India. Against the backdrop of the Foreign Contribution (Regulation) Act (FCRA) and shrinking Swedish aid, the study analyses how CSOs adapt to legal, political, and relational constraints. Drawing on four semi-structured interviews and guided by the concepts of

Organisms in the wild are faced with multiple threats and a common response is a change in behaviour. To disentangle responses to several threats, we exposed two differently sized species of the freshwater invertebrate Daphnia to solar ultraviolet radiation (UVR) and predation from either moving pelagic or benthic ambush predators. Using an advanced nanotechnology-based method, we tracked the thre

Checkpoint blockade therapies that reactivate tumour-associated T cells can induce durable tumour control and result in the long-term survival of patients with advanced cancers1. Current predictive biomarkers for therapy response include high levels of intratumour immunological activity, a high tumour mutational burden and specific characteristics of the gut microbiota2,3. Although the role of T c

A large portion of atmospheric aerosol particles consists of secondary material produced by oxidation reactions. The relative importance of secondary organic aerosol (SOA) can increase with improved emission regulations. A relatively simple way to study potential particle formation in the atmosphere is by using oxidation flow reactors (OFRs) which simulate atmospheric ageing. Here we report on the

Mental health problems affect the patients and their families, who may also need therapeutic interventions. Mindfulness interventions have shown beneficial health effects for clinical and healthy populations. A web-based mindfulness intervention was tailored to address families' needs of support and tested in a pilot intervention study. The aim of this study was to explore the participants' experi

The amyloid precursor protein intracellular domain (AICD), a cleavage product of amyloid precursor protein implicated in Alzheimer disease and amyloid lateral sclerosis, is a functionally important but structurally elusive intrinsically disordered protein. In this study, we investigate the conformational ensemble of a 35-residue AICD segment encompassing the conserved YENPTY motif using molecular
