The conformational entropy of proteins can make significant contributions to the free energy of ligand binding. NMR spin relaxation enables site-specific investigation of conformational entropy, via order parameters that parameterize local reorientational fluctuations of rank-2 tensors. Here we have probed the conformational entropy of lactose binding to the carbohydrate recognition domain of gale

We have previously shown that patch test preparations of polymeric diphenylmethane diisocyanate (PMDI) are more stable than preparations of diphenylmethane-4,4'-diisocyanate (4,4'-MDI). This study was conducted to (i) investigate whether PMDIs yield as many positive reactions as 4,4'-MDI, (ii) study concurrent reactions to 4,4'-MDI and 4,4'-diaminodiphenylmethane (4,4'-MDA), and (iii) follow the c

Studien syftar till att undersöka hur de olika trafikslagen prioriteras i gatuutrymmet i form av en kritisk granskning av Spårvägsprojektet i Lund. Arbetet ämnar utreda bland annat utrymmesbehovet för motorfordon, cyklister och fotgängare. Vidare undersöks disponeringen av gatuutrymmet för de olika trafikslagen i spårvägsprojektet i Lund och om det är i linje med kommunens uttalade mål och strategThe thesis aims to investigate the space requirements for motor vehicles, bicycles and pedestrians. Furthermore, it examines how the street space has been used for the various types of traffic in the tramway project in Lund and whether it is according to the municipality's stated goals and strategies. The study also investigates whether the final result corresponds to the initial plan of the p

Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. Målet med detta projekt var att undersöka hur olika dTreatment of wastewater is crucial for removing any compounds which can have a negative impact on human health and nature before the water is reused or released into nature. Interest in anaerobic treatment of wastewater has increased as it is a good complement to aerobic treatment, and it produces energy in form of methane. The aim of this project was to investigate how different operational para

In the field of computational biology, fluorescence microscopy images often constitute the input source of information. The process of binarization of raw images to delineate interesting objects requires image segmentation into signal and background pixels. Several methods to perform image segmentation exist, the Otsu method being a popular unsupervised example. The Otsu method's lack of pro

This master thesis is the result of cooperation between Lund University and Tetra Pak, performed by a student at Engineering Nanoscience, LTH. The aim is to explain how different molecular weights and molecular weight distribution of isotactic homo-polypropylene affect resulting properties. Examined properties are mechanical properties by tensile testing and tensile impact, shear viscosity by capi

The study was carried out to identify critical factors for processed fruit shelf life in Tetra Recart packages. To investigate the importance of package volume and headspace volume, vitamin C was chosen to be the indicator. Oxygen in headspace, headspace volume, dissolved oxygen in product, oxygen transmission rate (OTR) and the concentration of vitamin C along storage time were measured to unders

Intimate partner violence (IPV) is a major social problem and complex subject with a lack of research. Youths are a particularly vulnerable group when it comes to IPV. A larger risk of exposure and experience of violence during the teenage years may contribute to a larger risk of violent relationships in the future. It is therefore important to notice, educate and prevent violence at an early stag

The creation of floral resources for pollinators, such as flower strips, is seen as a relevant and needed intervention but comes with both cost and an opportunity for farmers. It may be worth it if, for example, pollinators are attracted to pollinator-dependent crops and deliver crop pollination. Unfortunately, since pollinators are mobile organisms, the spatial distribution of crop pollination re

Introducing a new employee into an organization is a critical time for the individual and the organization in question. Successful introductions can create high job satisfaction, increased performance, organizational commitment, and social integration – also called organizational socialization. There are many benefits of a successful socialization process; therefore, understanding what new employe

Terrestrial ecosystem models (TEMs) contain the coupling of many biogeochemical processes with a large number of parameters involved. In many cases those parameters are highly uncertain. In order to reduce those uncertainties, parameter estimation methods can be applied, which allow the model to be constrained against observations. We compare the performance and results of two such parameter estim

A two-stage system was investigated for anaerobic digestion (AD) of aerobically pre-treated sisal leaf decortication residue (SLDR) with regard to hydrolytic enzymes and biogas production. The system consisted of a solid-bed bioreactor for hydrolysis connected to methanogenic bioreactor packed with sisal fibre decortication residues (SFDR) as biofilm carriers. Some of the enzymes produced by micro

The accuracy, precision and limitations of the imaging technique named Structured Laser Illumination Planar Imaging (SLIPI) have been investigated. SLIPI, which allows multiply scattered light to be diminished, has previously demonstrated improvements in image quality and contrast for spray imaging. In the current study the method is applied to a controlled confined environment consisting of a mix

Epilepsy comprises a family of neurological disorders characterized by recurrent seizures, which can be highly debilitating. Up to 30% of patients with temporal lobe epilepsy, the most common form of the disorder in adults, arising in the hippocampus, cannot be effectively treated by current pharmaceuticals. Novel treatment strategies are highly needed, as well as increased understanding of the hi

Introduction: There is a shortage of tools designed for use by occupational therapy practice in Arabic-speaking countries. The purpose of this study was to translate and cross-culturally adapt the original Satisfaction with Daily Occupations tool to Arabic and assess the psychometric properties of the adapted tool. Method: A cross-cultural adaptation process was performed. Face, content, and crite

Fokus på offentliga diskussioner och vetenskapliga utforskningar som berör intim human-robot-interaction blir alltmer framträdande. Likväl saknas det psykometriska instrument avsedda för explorationen av intim social kontakt mellan människa och social robot. Det övergripande syftet med denna studie var att utveckla ett nytt psykometriskt test, Robot Intimate Receptiveness Scale (RIRS) för undersökPublic discussions and scientific inquiries centered around human-robot relationships are rapidly gaining momentum. As artificial intelligence integrates into new social landscapes, corresponding scientific explorations are called for. As of today, there are no psychometric instruments tailored to measure intimate social contact within human-robot contexts. In the light of this gap, the primary ob

About 20 percent of Sweden's municipal street network is now in urgent need of maintenance. This is assumed to correspond to a cost of about 12 billion Swedish crowns. That the streets are maintained in an effective manner is of great importance both for the users' safety and accessibility. Today, however, numerous municipalities suffer from a maintenance debt incurred because of the lack

This project’s objective was to gather knowledge of ways to mechanically increase speech intelligibility and decrease wind noise through the design of microphone ports. The project focused on ports that would be applied in outdoor intercom products. The project used experimental testing through the development method Robust Design to investigate different parameters that could be changed in a

This essay examines the typographic discussions in Sweden around the turn of the 20th century. The focus lies on Gothenburg-based printer Waldemar Zachrisson, a driving force in these matters. The starting-point of the study is the industrialization of the printing in the 19th century, when printing changed from being a craft to being a largely mechanical process. Several voices from the turn of t
