Kan mjölk skydda mot gropfrätning på processutrustning av rostfritt stål och hur kan man testa det? Tetra Pak säljer högspecialiserad processutrustning till livsmedelsproducenter och utrustningen är ofta tillverkad av rostfritt stål. Stålet motstår många typer av rost, men gropfrätning är en typ av korrosion som påverkar stålet vid framför allt höga temperaturer och höga salthalter. Dessa förutsäThis master’s thesis is written for Tetra Pak with the aim to investigate if pitting corrosion inhibition can be detected for Stainless Steel 316L in contact with dairy products in an experimental setup. The aim was also to continue developing a corrosion test method to facilitate for material selection of food pro- cessing equipment in order to reduce the extent of detrimental pitting corrosion.

Detection of tool wear is critical in optimizing tool change strategies and cutting parameter selection to influence productivity, cost, and quality in metal cutting. Nonetheless, current practices for tool wear detection majorly depend on manual, inconsistent, and time-consuming visual inspection by operators. Tool wear detection has the potential to greatly benefit from recent advances in artifi

This has been done through interviews with representatives of Institut for (x) and Aarhus municipality, where the

The purpose of the study was to gain a better understanding of informal leadership on the flight deck and how leadership can be effectively practiced by a first officer from the right seat, with the intention to strengthen team performance. The research question tried to answer if informal leadership is present on the flight deck and what factors contribute to the first officer’s ability to influe

Uppsatsen är en narrativanalys som undersöker ur ett postkolonialt perspektiv Förenta Nationernas (FN) aktörskap i kriser, specifikt epidemier som inte orsakats av särskilda aktörer. Epidemierna som analyseras är aidskrisen (1981-1990) och ebolakrisen (2013-2016) med ursprung i Afrika. Inom den internationella politiska sfären är FN en stor aktör. Det är en av modern tids viktigaste samlingsplatse

Den här studien har skapats för att effektivisera analysen av tabletter innehållande den aktiva substansen nikotin på Kenvue. Nuvarande teknik för att analysera nikotinhalten i 2 och 4 mg tabletter är vätskekromatografi (UHPLC), en tidskrävande teknik som kräver provupparbetning. Near infrared (NIR) spektroskopi är en snabb analysteknik som är icke-destruktiv och kräver ingen provupparbetning vilkA study has been created to develop a method quantifying the active pharmaceutical ingredient (API) nicotine in tablets with near infrared (NIR) spectroscopy using chemometrics. The current technique, liquid chromatography (UHPLC), used to determine the nicotine content in tablets is time consuming and require sample preparation. NIR spectroscopy is non-destructive and the implementation of NIR sp

Syfte: Att undersöka hur yrkesverksamma arbetsterapeuter förhåller sig till sexuell hälsa och sexualitet i arbetet med vuxna klienter inom psykiatrin. Metod: En kvalitativ studie baserad på nio iBackground: Sexual health and sexuality are part of everyday life. In mental health services it is an important topic to address since mental illness can negatively impact the client’s sexuality and relationships. Aim: To explore occupational therapist’s approach to sexual health and sexuality in their work in mental health services with adults. Method: A qualitative study based on nine interview

Vår galax, Vintergatan, är en något större än normalt, stavspiralgalax. Som en sådan stor galax har den förmågan att rymma enorma massor av interstellärt medium (ISM), inklusive gas som utkastas från stjärnor när de exploderar till supernovor i slutet av sina liv. I denna explosion kastas tyngre element som producerats i stjärnan genom fusion ut. När denna process fortsätter och ISM fylls mer och In this study, over 2000 Milky Way stars were analyzed in the [Mg/Mn] vs [Al/Fe] chemical plane to identify accreted stars. The Milky Way's faster star formation enriches disk stars with iron-peak elements such as Mn and reduces alpha elements like Mg. Accreted stars, originating from slower star formation rate environments, exhibit lower metallicities, reflected in lower [Al/Fe]. The study ev

In an era dominated by digital interfaces, our desire to reintegrate tactile and physical elements into our daily interactions has intensified. By acknowledging the resurgence of vinyl records and the persistent rise of physical music formats, our project seeks to recapture the ritual of music listening that has been lost in the digital age. Our design reflects a conscious effort to create a funct

To meet 2030 climate goals, industries and governments are adopting circular economy principles to mitigate the building industry's environmental impact through reusing, recovering, and recycling. This report incorporates circularity by examining the adaptive reuse of HVAC components in a case study in Malmö, Sweden. Firstly, the report determined which elements of an HVAC system had the highe

This thesis deals with the characterization of the approved inner tracker upgrade of the ALICE experiment involving an innovative and ultra-thin silicon detector with a cylindrical geometry. During this thesis work, Monolithic Active Pixel Sensors (MAPS) were studied for the first large-scale prototype of the upgrade, together with a sensor of the same technology with smaller size. Properties of t

This study examined discussions of the "LVU Campaign" on the Swedish forum "Flashback". LVU, the Swedish Care of Young Persons (Special Provisions) Act (SFS 1990:52), allows social services to take children into care without parental consent if it is in the best interest of the child. Discourse analysis, using Discourse Theory, was conducted on three forum threads. Two discours

Every day more devices all over the world are connected to networks. Some of these devices have microphones that could potentially be used in a networked array. This opens up the possibility to determine where sounds in the environment are produced, given the positions of the microphones are known. This thesis investigates the feasibility of using a number of network connected speakers with built-

This thesis investigates the causal relationship between board diversity and the performance of firms that have gone public in the Nordics through Initial Public Offerings (IPOs) during the 2020s, a period characterised by significant economic, regulatory, and demographic shifts. By implementing a robust instrumental variable (IV) approach with the Bartik shift-share instrument, the study examines

Amidst global efforts to address pressing environmental challenges and achieve the Sustainable Development Goals, education for sustainable development emerges as a pivotal tool for fostering societal transformation towards a more sustainable future. Within this context, competence frameworks serve as essential guidelines for integrating sustainability into education. This research investigates th

I centrum av vår galax, Vintergatan, finns ett supermassivt svart hål som är mer än fyra miljoner gånger så massivt som solen. Runtom detta supermassiva svarta hål, ibland kallat Sagittarius A* (Sgr A*), finns ett extremt tätt kluster av stjärnor som utgör det nukleära stjärnklustret. För att förstå hur tätt detta kluster faktiskt är så kan vi jämföra det med avståndet till solens närmaste granne,The Milky Way harbors a supermassive black hole (SMBH) at its dynamical center. Surrounding the SMBH is a dense nuclear star cluster (NSC) which is believed to include a binary population. Beyond $0.1\mathrm{pc}$ from the SMBH, Eccentric-Kozoai Lidov oscillations are suppressed by general relativity precession, and the dynamical evolution of binaries are completely dominated by encounters with oth

Med hänvisning till den europeiska pelaren för sociala rättigheter antog unionslagstiftaren den 19 oktober 2022 ett direktiv om minimilöner. Direktivet mötte under lagstiftningsprocessen stark kritik från Danmark och Sveriges regeringar vilka var de enda medlemsstater som röstade emot kommissionens förslag i rådet. En förklaring till detta är att både Sverige och Danmark saknar lagstadgade minimilFollowing the European Pillar of Social Rights, the union legislator adopted a directive on minimum wages on 19 October 2022. During the legislative process, the directive was heavily criticised by the Danish and Swedish governments, which were the only member states to vote against the Commission's proposal in the Council. One explanation for this scepticism is that neither Sweden nor Denmark

The legal case known as “Lilla hjärtat” became a widely discussed case in Sweden, where the debate about the best interest of the child was reborn. The case later led to the change in the law we know today as “lex Lilla hjärtat”. However, it has been revealed in new inspections that there are still faults regarding the child rights perspective in child protective work. The aim of the study was the
