The presented thesis work is concerned with the study of molecular dynamics using liquid nuclear magnetic resonance (NMR) spectroscopy. Spin relaxation dispersion experiments in the rotating frame (R_1ρ) are employed to provide a detailed, atomic-resolution view of protein dynamics. Comprehensive investigations of ¹⁵N backbone and ¹³C methyl side-chain confo

Popular Abstract in Swedish Att en elektrisk urladdning ger upphov till ljus syns varje gång blixten slår ner. Den omvända processen, att ljus kan skapa en elektrisk urladdning, upptäcktes av Hertz 1887 som en parentes i utvecklingen av radiomottagare. Undersökningar av detta fenomen visade att elektroner bara kunde frigöras av ljus som hade tillräckligt hög frekvens (ultraviolett). Förklaringen a

The project's main thesis is to verify the existence of local colours and colouring. The object for the research was dwellings in the rural areas of southern Sweden from the 19th century. In the rural areas of Sweden the most dominating traditional facade material is wooden panel. The colour at these facades is the traditional red-paint. It’s relevant for this project to take focus on geographical

Ecosystem services that people depend upon for their well-being are being lost at an alarming rate. These services include the provisioning of natural resources, food, medicine, flood protection, climate regulation, water purification, and biodiversity retention. In the U.S., the main threat to these services comes from the rapid pace of land conversion. In just a twenty- year period, an area the

Roten till cancer? Cancer är en ledande orsak till en stor mängd dödsfall i världen och därför en fruktad sjukdom. Forskningen gör dock framsteg och man kommer allt närmre svaren på gåtorna. På senare år har det föreslagits att en speciell typ av celler, cancerstamceller, är drivande och ligger bakom flera av cancersjukdomarnas egenskaper. Alla organismer är uppbyggda av celler, den stora majoriIn recent years increasing evidence supporting the stem cell hypothesis have emerged and cancer stem cells (CSCs) have been reported to have been isolated in a wide variety of cancers. This CSC population has been attributed to contribute to the therapeutic resistance of many cancers and it is thus of great interest to find new therapeutic options targeting these cells. In ileal carcinoids however

Priming effects have gotten revived interest in the last decade due to the concerns of global warming. Priming are defined as an increase in decomposition of soil organic matter due to the addition of organic or mineral substances. The worldwide used herbicide glyphosate is rapidly degraded by microorganisms. Hence, it might give rise to priming effects in soils. This was tested by adding glyphosa

Aim: To analyse morbidity and mortality in healthy newborn infants in relation to various routines of post-natal follow-up. Design: cross-sectional study. Setting: maternity care in Sweden. Population: healthy infants born at term between 1999 and 2002 (n = 197 898). Methods: Assessment of post-natal follow-up routines after uncomplicated childbirth in 48 hospitals and data collected from the Swed

Massive MIMO can greatly increase both spectral and transmit-energy efficiency. This is achieved by allowing the number of antennas and RF chains to grow very large. However, the challenges include high system complexity and hardware energy consumption. Here we investigate the possibilities to reduce the required number of RF chains, by performing antenna selection. While this approach is not a ve

The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S

We present a detailed experimental and numerical study of the structural and dynamical properties of salt-free lysozyme solutions. In particular, by combining small-angle X-ray scattering (SAXS) data with neutron spin echo (NSE) and rheology experiments, we are able to identify that an arrest transition takes place at intermediate densities, driven by the slowing down of the cluster motion. Using

This thesis examines whether the Fama & French three-factor model (1993) provides a better explanation of Swedish stock returns than the traditional Capital Asset Pricing Model (CAPM). Using data from firms listed on Nasdaq Stockholm between 2016 and 2024, six portfolios were formed based on firm size and price-to-book ratio. Monthly returns were calculated and regressed against both the marke

Understanding the relationships between snow and vegetation is important for interpretation of the responses of alpine ecosystems to climate changes. The Qinghai-Tibetan Plateau is regarded as an ideal area due to its undisturbed features with low population and relatively high snow cover. We used 500 m Moderate Resolution Imaging Spectroradiometer (MODIS) datasets during 2001–2010 to examine the

Objective. To investigate the relationship between migration status and sedentary leisure-time physical activity status in the city of Malmö, Sweden. Methods. The public health survey in 1994 is a cross-sectional study. A total of 5600 individuals aged 20-80 completed a postal questionnaire. The response rate was 71%. The population was categorized according to country of birth. Multivariate analy

Objective: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. Methods: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein param

Removal of cyprinid fish is a widely used biomanipulation tool to transform turbid shallow eutrophic lakes in north temperate regions into a clear water state. We here evaluate the removal of cyprinids from streams as a supplement to lake fishing. Since cyprinids often aggregate in high densities in lake inlet/outlet streams during winter migration, removal of fish in this space-confined habitat m

To increase the productivity in biopharmaceutical production, a natural step is to introduce integrated continuous biomanufacturing which leads to fewer buffer and storage tanks, smaller sizes of integrated unit operations, and full automation of the operation. The main contribution of this work is to illustrate a methodology for design and control of a downstream process based on integrated colum
