Intrinsically disordered proteins are fully functional proteins without a three-dimensional structure. Intrinsically disordered proteins can, in the same way as ordered proteins, interact with other proteins to fulful their function. When intrinsically disordered proteins interact with other proteins they can form complexes, so-called fuzzy complexes, with different degrees of disorder still prese
This essay investigates what housing size is the optimal for the average student in Lund. The optimal housing size for the average student is defined as the size that maximizes the average student’s net benefit from size in monetary terms. It is found by equating the marginal willingness to pay for size and the marginal cost for size. The marginal willingness to pay is derived from estimates of ch
Trash can harm both the environment and humans. It can maintain for a long time in the environment before degrading and during that time it can pollute soils and poison animals. This study focuses on the Pellekan campaign which started to reduce littering in the city of Mölndal. The campaign has been working the same way from the start in 2002 and now is time to evaluate how well it worked. For th
The goal with this master thesis is to examine the usability in the Tetra PlantMaster. Tetra PlantMaster is the control system for the dairies that Tetra Pak develops. Tetra PlantMaster is the system which the operator uses in order to govern the entire process when raw milk becomes a product ready to be delivered to the grocery stores. This includes applications to produce soured milk, yoghurt, i
Poly-N-isopropylacrylamide (PNIPAM) microgels are versatile colloidal-scale polymer networks that exhibit unique responsiveness to external stimuli, such as temperature. While the synthesis of PNIPAM microgels is well-documented, there is limited exploration of how their structural properties can be modified by subtle changes in the polymerization process. In this work, we carefully investigate ho
Organ function depends on the three-dimensional integrity of the extracellular matrix (ECM). The structure resulting from the location and association of ECM components is a central regulator of cell behavior, but a dearth of matrix-specific analysis keeps it unresolved. Here, we deploy a high-resolution, 3D ECM mapping method and design a machine-learning powered pipeline to detect and characteri
In this article I look at two works by Swedish video artist Lina Selander and explore how underlying visual patterns unfold in these works that are connected to certain worldly phenomena. Borrowing from Jacques Derrida, I describe the tendency of being en mal d'archive as an obsession to structure the world into particular recognizable patterns. I argue that Selander's works can be understood as t
Experimental microbial ecology and evolution have yielded foundational insights into ecological and evolutionary processes using simple microcosm setups and phenotypic assays with one- or two-species model systems. The fields are now increasingly incorporating more complex systems and exploration of the molecular basis of observations. For this purpose, simplified, manageable and well-defined mult
Medical waste management has been receiving increasing attention in recent years. The National Health Service (NHS) of the United Kingdom has started planning its waste strategy to comply with its Net Zero Goals. Waste management does not only involve waste disposal; the process includes segregation, collection, storage, and the transportation of waste from one point to another. Unusual characteri
Determination of pK(a) values of titrating residues in proteins provides a direct means of studying electrostatic coupling as well as pH-dependent stability. The B1 domain of protein G provides an excellent model system for such investigations. In this work, we analyze the observed pK(a) values of all carboxyl groups in a variant of PGB1 (T2Q, N8D, N37D) at low and high ionic strength as determine
During the last years evaluation has been on the agenda as a part of the discourse in social work and social services in Sweden. This demand on evaluation and the value of the social work is connected to the tough economic situation in the municipalities and their growing responsibility for the social welfare services. At the same time there are strivings to improve the quality of social work and
Popular Abstract in Swedish För analys av agroekosystems näringsämnescirkulation presenteras här en generell modell. I centrum står födoproduktionsintensitet, mänsklig bärförmåga, uthållighet och effektivitet. Modellen kan användas på system med flera markanvändningstyper och är därför lämpad för studier i olika skalor. Jämförelser av alla slags agroekosystem, oavsett tid och rum, är möjliga. Olik
The stress field in a finite, edge cracked specimen under load is computed using algorithms based on two slightly different integral equations of the second kind. These integral equations are obtained through left regularizations of a first kind integral equation. In numerical experiments it is demonstrated that the stress field can be accurately computed. Highly accurate stress intensity factors
Background: Vibration to the head or neck excites vestibular and neck muscle spindle afferents. Can such vibrations improve the sensitivity of the subjective visual horizontal (SVH) test to chronic unilateral deficit of the vestibular system? Design: Controlled experimental study. Setting: Tertiary referral center. Patients and Controls: Thirteen healthy subjects and 23 patients with chronic unila
The creation of 3D scaffolds that mimic the structure of physiological tissue required for normal cell function is a major bioengineering challenge. For corneal stroma reconstruction this necessitates the creation of a stroma-like scaffold consisting of a stack of orthogonally disposed sheets of aligned collagen fibrils. This study demonstrates that such a scaffold can be built up using magnetic a
Background. D-galactosamine together with lipopolysaccharide can lead to a pronounced secretion by Kupffer cells of pro-inflammatory mediators, which have been shown to be early and important mediators of liver injury. Probiotics and dietary supplementation with fruit or vegetable extracts with high content of antioxidants, such as blueberry, could be beneficial in protecting against hepatotoxicit
