Vulnerability maps of groundwater provide an efficient means of identifying environmental trends and prioritizing regions for prevention plans. The GIS-based DRASTIC method, however, does not consider the impact of contamination, so there is a need to modify it according to the specifics of the region and its contamination load. The aim of this study is to investigate a suitable DRASTIC modificati

Initiatives to upscale repair activities are becoming increasingly common, with the latestbeing the EU commission’s proposal to strengthen consumers’ right to repair. However, theseinitiatives are not viewed comprehensively, particularly not for how they impact the product user’sexperience of the repair process, and what type of repair conditions would emerge once fullyimplemented. This gap exists

Denna studie syftar till att fördjupa förståelsen av konsumenters uppfattningar av värde i servicemöten som inkluderar självbetjäningsteknologier i jämförelse med personlig service. Genom att tillämpa kvalitativa forskningsmetoder utforskar studien hur konsumenter bedömer och beskriver olika aspekter av dessa servicemöten samt deras påverkan på individen. Resultaten indikerar att medan självbetjän

The SM2RAIN (soil moisture to rain) model has been widely used for rainfall estimation worldwide. However, due to the lack of sufficient ground observation, the SM2RAIN model driven by different passive microwave soil moisture products over the Tibetan Plateau has not been fully validated. In this article, four widely used satellite microwave soil moisture products (including SMAP, ASCAT, SMOS, an

The growing popularity of nature-based tourism means that the tourism industry is increasingly utilizing wilderness areas to provide visitor experiences. However, tourism activities negatively impact wilderness quality. Tourism service providers play an important role in shaping these impacts. Therefore, this study investigates their preferences regarding wilderness use and development. It focuses

Denna kandidatuppsats fokuserar på införandet av AI inom e-handel i Sverige. En kvalitativ metod antogs genom att intervjua yrkesverksamma som arbetar inom e-handelssektorn. Resultaten presenterades med hjälp av TOE-ramverket. Denna studie syftar till att få insikter i hur e-handelsföretag använder AI-teknik och vilka utmaningar de stöter på. Därmed bidrar denna avhandling till forskningen genom aThis thesis focuses on the adoption of AI within e-commerce in Sweden. A qualitative approach was adopted, interviewing professionals working in the e-commerce sector. Results were presented using the Technology-Organization-Environment (TOE) framework. This study aims to gain insights into how e-commerce companies adopt AI technologies and the challenges they encounter. Thus, this thesis contribu

The performance of HVAC equipment, including chillers, is continuing to be pushed to theoretical limits, which impacts the necessity for advanced control logic to operate them efficiently and robustly. At the same time, their architectures are becoming more complex; many systems have multiple compressors, expansion devices, evaporators, circuits, or other elements that challenge control design and

AIMS: The aim of this study is to investigate how genetic variations in genes related to oxidative stress, intake of antioxidant vitamins, and any potential interactions between these factors affect the incidence of intact abdominal aortic aneurysm (AAA) and its rupture (rAAA), accounting for sex differences where possible.METHODS AND RESULTS: The present retrospective cohort study (n = 25 252) us

Background: Eugenol is a known contact sensitiser included in fragrance mix I. Objective: To assess the allergic reactivity to eugenol in different concentrations using patch test as well as repeated open application test (ROAT). Methods: Overall 67 subjects from 6 European dermatology clinics participated in the study. The ROAT was performed for 21 days twice a day, applying 3 dilutions of eugeno

Aspects of spatial and temporal rainfall variability and rainfall analysis in relation to some water management problems are surveyed and discussed. It is concluded that relevant modelling of hydrological processes in which the rainfall is a driving force is vital with respect to possibilities of finding solutions to increasing environmental problems following urbanization and industrialization. H

The unique properties of elastomeric materials are taken advantage of in many engineering applications. Elastomeric units are used as couplings or mountings between stiff structures. Examples of these are shock absorbers, vibration insulators, flexible joints, seals and suspensions.The development of computers and of analysis programs in this area has given engineers a new tool for the design of e

Luftföroreningar dödar 7 miljoner människor varje år och är därmed enligt WHO ett av de största hälsohoten i vår tid. Hälsoeffekterna av luftföroreningar kan vara akuta eller kroniska och de kan drabba flera olika organsystem, bland annat lungor och hjärta. En grundpelare i att åtgärda dessa problem är att kunna mäta och uppskatta hur utsatta vissa individer är för luftföroreningar. Gällande just Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. Method: A mathematical model has been developed in

We investigate self-heating in vertical, gate-all-around III-V InAs/InGaAs nanowire MOSFETs using pulsed IV measurements at various temperatures. Low temperature measurements reveal a negative output conductance indicating self-heating in the transistor. Under pulsed measurements, an increase in drain current (15%) and transconductance (30%) are observed at room temperature, with values influenced
