Finding a wear resistant coating for cemented carbide cutting tools in the machining of difficult to cut Ti alloys is a challenge due to their high strength and chemical reactivity. Tool manufacturers recommend physical vapor deposited (PVD) TixAl1-xN (x = 0.4–0.7), and an extra NbN overlayer has shown promising potential. This study explores wear mechanisms of PVD Ti0.45Al0.55N with and without N
Kraft lignin is an underutilized resource from the pulp and paper industry with the potential of being a key raw material for renewable fuels and chemicals. The separation of high-molecular-weight lignin from black liquor by ultrafiltration has been widely investigated, while the permeate containing low-molecular-weight lignin has received little attention. Nanofiltration can concentrate the low-m
This thesis examines the role of beamlines with publication metadata from the European Synchrotron Radiation Facility (ESRF a large scientific facility offering diverse conditions for scientific research. As a user-oriented Big Science facility, the ESRF channels extremely brilliant light into different experimental areas called beamlines that house specific instruments that cater to the needs of
Popular Abstract in Swedish Ett glas mjölk innehåller ungefär tusen miljarder små oljedroppar. Varje droppe är en tusendels millimeter stor. Dropparna är suspenderade i en blandning av vatten, proteiner och lösta molekyler. Små droppar av olja i vatten brukar kallas emulsioner. Emulsioner är vanliga beståndsdelar i livsmedel och finns exempelvis i allehanda mjölkprodukter, såser, smeter och dressiDifferent approaches and sub-models for the modelling of emulsification in a high-pressure homogenizer are reviewed and compared in terms of both practical aspects and how well they describe what is currently known on the emulsification process in general and on high-pressure homogenization in particular. Special effort is devoted to comparing the model developments presented in the appended paper
The subject of the present thesis is children’s rights in the process of debt collection. The main focus of the thesis is article 3.1 of Convention on the Rights of the Child (CRC) and its legal relevance in proportionality tests prior to decisions on seizure and sales of houses and apartments in Swedish insolvency law. The thesis is based on two studies. One legal dogmatic study on Swedish enforc
The visual appearance of an object is a function of stimulus properties as well as perceptual biases imposed by the observer. The context-specific trade-off between both can be measured accurately in a perceptual judgment task, involving grouping by proximity in ambiguous dot lattices. Such grouping depends lawfully on a stimulus parameter of the dot lattices known as their aspect ratio (AR), whos
In small systems with large fluctuations, the classical description of thermodynamics is no longer sufficient which has led to the development of stochastic thermodynamics. One important result from stochastic thermodynamics is that with measurement and feedback it is possible to use those fluctuations to extract work from a single heat bath coupled to the system. This is thanks to the connection
Flame front structure is one of the most fundamental characteristics and, hence, vital for understanding combustion processes. Measuring flame front structure in turbulent flames usually needs laser-based diagnostic techniques, mostly planar laser-induced fluorescence (PLIF). The equipment of PLIF, burdened with lasers, is often too sophisticated to be configured in harsh environments. Here, to sh
The implementation of the Biofuels Directive (2003/30/EC) in the 25 member states is assessed against the background of implementation theory in this paper. The aim is to identify and analyze implementation problems for the purpose of suggesting a way forward for biofuels policy in the European Union. Three main patterns of policy implementation are observed: effective implementation, formal compl
Essential tremor (ET) is characterized by bilateral upper limb postural and/or kinetic tremor, but also cognitive deficits. Tremor in ET, as well as aspects of cognitive deficits associated with ET, have been suggested to be linked to dysfunction in the cerebello-thalamo-cerebral circuit. In ET patients with disabling and medically intractable motor symptoms, Deep Brain Stimulation (DBS) is effect
The paper expands the conceptual framework within which we examine mortgage debt by reconceptualising mortgages as a biotechnology: a technology of power over life that forges an intimate relationship between global financial markets, everyday life and human labour. Taking seriously the materiality of mortgage contracts as a means of forging new embodied practices of financialisation, we urge for
Architecture is always intrinsically tied to place. Regardless of how architects choose to interact with and study it, the context our buildings are meant to inhabit is an important piece of the puzzle. As the world is getting more interconnected and geographical constraints are getting less important to the architectural profession, I am interested in how the creative process changes when assumpt
The most common controller in the process industry today is the PID controller due to its simple structure. A regular factory may have thousands of different PID controllers in use where each of them has to be tuned to work satisfactory. Doing this manually can become both a difficult and time consuming task where some knowledge for each process is required. Therefore, it is highly beneficial to h
Korslimmat trä, KL-trä, är ett förhållandevis nytt byggnadsmaterial i byggbranschen. Det består av ett udda antal skikt av lameller av konstruktionsvirke, där varje skikt av lameller ligger roterade 90 grader i förhållande till intilliggande skikt. Materialet används både i den bärande stommen och som stomkomplettering i form av exempelvis trappor. Idag finns endast en etablerad tillverkare på dCross-laminated timber, CLT, is a rather new building material. It consists of an odd number of layers consisting of lumber boards stacked together, where each layer is rotated 90 degrees in comparison to the adjacent layers. The material is used both as a load-carrying element as well as a non-load-carrying element, such as stairs. Today there is only one established producer of CLT in Sweden. D
Humanitarian aid workers (HAWs) face increasing risks in conflict zones, with 2024 marking the deadliest year on record. International humanitarian organisations (IHOs) must address this trend to continue delivering aid and protecting HAWs. This study investigates how IHOs adapt to the evolving risks in these contexts and explores challenges that adaptation measures may entail. A qualitative resea
In modern recruitment, organizations tend to face a persistent paradox: they must align candidates with existing cultural values while simultaneously promoting workforce diversity. This thesis investigates how HR professionals navigate the inherent tension between organizational fit and diversity within recruitment processes across multinational public and private organizations in Europe and South
A well-known maxim defines politics as "the art of the possible". This definition implies that the nature of politics is relative to specific circumstances and derives from an adoption of the line of action possible under given circumstances; correlated to this is a rejection of political activities whose realisation is impossible while being subjected to these circumstances. This essay
Cooperative and reciprocal practices within agriculture have been widely discussed as important strategies in order to reduce risks and costs of labour and capital acquisition. Within the Andes reciprocal norms appear to be particularly institutionalized due to their historical rootedness in Andean culture. With the present case study I sought to examine reciprocal exchange practices in agricultur
Like many other international human rights law instruments, the 1951 Convention relating to the Status of Refugees was written from a male perspective, which has resulted in that the refugee definition of the Convention historically has been interpreted through a framework of male experiences. For this reason, many asylum claims of female applicants have been ignored. In order to be granted refug
