The initial adhesion of bacterial cells to implant surfaces is a critical step in the development of biofilms, complex microbial communities that are highly resistant to conventional antimicrobial treatments. Once established, these biofilms and their self-produced extracellular matrix are difficult to eradicate. As a result, there is growing interest in engineering implant surfaces that can effec
A one-dimensional model of reactive sedimentation in wastewater treatment is formulated. The model combines three main elements: the Activated Sludge Model No. 1 (ASM1) for the reactive part, a secondary sedimentation tank (SST) with a variable cross-sectional area, and a description with percentages of the solid phase. The final form of the model is a system of partial differential equations of t
Spatial compositional data with exact zeros arise in many applicationsbut remain challenging for models that often assume strictly positivecomponents. We develop a Bayesian spatial model that combines theDirichlet Composition Distribution, which accommodates exact zeros throughcomponent-specific zero probabilities, with a Gaussian Markov random field representationof the latent compositional field
Circular economy (CE) policy has largely developed around product markets, where ecodesign, repairability requirements, and extended producer responsibility now form a substantial regulatory layer. In regulated energy infrastructure, where replacement decisions are shaped by depreciation schedules, regulatory review cycles, and procurement rules, these tools have made limited progress. This perspe
This paper presents a decision-analytic approach for evaluating risk reduction actions for structural systems under climate change. A decision-theoretic formulation is developed to quantify the value of actions, extended to address climate change scenario uncertainties. Scenario occurrence probabilities are derived from probabilistic effective radiative forcing exceedances to link climate model pr
Surgery is often viewed as a lifesaving intervention, yet recovery depends just as much on what follows. The concept of individualised anaesthesia and analgesia in surgery challenges the traditional one-size-fits-all model by tailoring care to each patient's physiological and psychological profile, with the potential to improve outcomes, reduce complications, and enhance the patient experience. Ma
We study the time complexity of computing the (min,+) matrix product of two n×n integer matrices in terms of n and the number of monotone subsequences the rows of the first matrix and the columns of the second matrix can be decomposed into. In particular, we show that if each row of the first matrix can be decomposed into at most m1 monotone subsequences and each column of the second matrix can b
MST, eller O Movimento dos Trabalhadores Rurias Sem Terra (Rörelsen för Lantarbetare utan Jord), är en av latinamerikas och kanske världens största och mest inflytelserika sociala rörelser. Rörelsen är dessutom verksam i en av världens största politiska, ekonomsika, kulturella och sociala smältdeglar. I vår uppsats vill vi undersöka, dels vilka metoder som en social rörelse kan tillämpa när det g
Populärvetenskaplig sammanfattning: Målet med studien är att se vilka samband som finns mellan insamlad fältdata och beräknad satellitdata för bokskogsbestånd i södra Sverige (Häckeberga naturreservat och naturområde). Fältdata som använts består av uppskattat bladyteindex, beräknad biomassa samt kategoriserade åldersgrupper av 19 provytor bokskog (Fagus Sylvatica), indelat i tre grupper. ProvytorThe aim of this investigation is to study the relationship between leaf area index, biomass and satellite reflectance data of some beech forests (Fagus Sylvatica) in southern Sweden (Häckeberga nature reserve). In 19 forest stands, measurements of tree structural parameters like tree height and tree diameter at breast height were performed. In addition, the leaf area index was estimated optically
This study is a part of the research project Learning in the ICT-extended university (LiEU), which is conducted by Centre for Learning Lund at Lund University. The purpose of this study is to describe and analyse how upper secondary school students have experienced the Young Masters Program (YMP) and their learning process in the field of sustainable development in the ICT-mediated course with iss
Problem discussion: Syncron experience a challenge in realizing the full market potential of its newly developed IT-based price management system, Global Price Management (GPM). The system has already been implemented and is currently running with success within the IT-structures of the first customer. The fact that the development of the system has been initiated by a customer, and thereby has le
Uppsatsen behandlar en på statliga Lantmäteriverket genomförd fallstudie där medarbetarnas förståelse för arbetet undersöks med fokus på deras tidigare yrkesbakgrund.
Thesis purpose: The purpose of the master thesis is to analyse the battle of meaning creation regarding the notion of smoking and to reveal the production of unequal power relations. The battle is fought by different stakeholders through means of language and the study focuses on the tobacco industry in Germany. Methodology: A critical discourse analysis is applied with a qualitative research stra
Syfte: Syftet är att skapa ett verktyg som kan användas av riskkapitalister för att analysera, bedöma, jämföra och dokumentera entreprenörsföretag i avseendet att öka träffsäkerheten av såddfasinvesteringar. Metod: Valet av metod i uppsatsen har genomgående varit kvalitativa djupintervjuer. Initialt intervjuades riskkapitalister för att belysa den problematik som finns vid bedömning och värdering
Syfte: Syftet är att undersöka vad noterade företag anser om Övervakningspanelens roll och arbete samt dess funktion att kontrollera att tillämplig redovisningslagstiftning och god redovisningssed efterföljs i de finansiella rapporterna. Utifrån detta ska vi undersöka om Övervakningspanelens arbete anses vara legitimt. Metod: Vi har genomfört en explorativ kvantitativ enkätundersökning samt en int
Microfluidic applications nowadays have become of great interest due to their broad compatibility especially in biological applications, and one of them being droplet-based cell encapsulation. Cell encapsulation in droplets is carried out by discretising an aqueous phase (i.e. cell suspension) and including them into a continuous oil phase. This methodology is a potential gateway to high throughpu
Purpose: According to literature there is a set of six key competencies that distinguish sustainability professionals, including researchers, from professionals and researchers in other fields, making them “systemic problem solvers, change agents, and transition managers”. However, there is lack of empirical evidence, first, that these skills are necessary and sufficient for sustainability problem
Med en urban expansion världen över krävs det idag att biologisk mångfald räknas med vid utveckling av städer och omkringliggande ytor. I Ronneby kommun skall området Kilen omvandlas från att ha varit ett gammalt industriområde till att bli en ny stadsdel med bostäder, arbets- och handelsmöjligheter samt grönytor som kan fungera för rekreation och gynnande av biologisk mångfald. För utvecklingen a
