The ratio of the electric and magnetic form factors of the proton G(Ep)/G(Mp), which is an image of its charge and magnetization distributions, was measured at the Thomas Jefferson National Accelerator Facility (JLab) using the recoil polarization technique. The ratio of the form factors is directly proportional to the ratio of the transverse to longitudinal components of the polarization of the r
Smoking is a leading cause of preventable death, causing about 5 million premature deaths worldwide each year(1,2). Evidence for genetic influence on smoking behaviour and nicotine dependence (ND)(3-8) has prompted a search for susceptibility genes. Furthermore, assessing the impact of sequence variants on smoking-related diseases is important to public health(9,10). Smoking is the major risk fact
Polymorphisms in genes that encode for metabolic enzymes have been associated with variations in enzyme activity between individuals. Such variations could be associated with differences in individual exposure to carcinogens that are metabolized by these genes. In this study, we examine the association between polymorphisms in several metabolic genes and the consumption of tobacco in a large sampl
Using genome-wide data from 253,288 individuals, we identified 697 variants at genome-wide significance that together explained one-fifth of the heritability for adult height. By testing different numbers of variants in independent studies, we show that the most strongly associated ∼2,000, ∼3,700 and ∼9,500 SNPs explained ∼21%, ∼24% and ∼29% of phenotypic variance. Furthermore, all common variants
Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have three main limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically.

Three founder mutations in BRCA1 and BRCA2 contribute to the risk of hereditary breast and ovarian cancer in Ashkenazi Jews (AJ). They are observed at increased frequency in the AJ compared to other BRCA mutations in Caucasian non-Jews (CNJ). Several authors have proposed that elevated allele frequencies in the surrounding genomic regions reflect adaptive or balancing selection. Such proposals pre

Projektet HITS/Transparens utforskar hur frivillig användning av informations- och kommunikationsteknologi av privata aktörer kan förbättra informationstransparens i transport av farligt gods. Detta tillvägagångssätt skiljer sig från en lång rad projekt som sedan 80-talet haft ett centralt myndighetsperspektiv på informationshantering kring farligt gods. I linje med tidigare resultat inom forsknin
OBJECTIVE: Eleven genetic loci have reached genome-wide significance in a recent meta-analysis of genome-wide association studies in Parkinson disease (PD) based on populations of Caucasian descent. The extent to which these genetic effects are consistent across different populations is unknown.METHODS: Investigators from the Genetic Epidemiology of Parkinson's Disease Consortium were invited to p
Placement errors of object clitics (OCL) in French have been documented in 2L1 and L2 but not in L1 acquisition (Granfeldt 2012; Hamann & Belletti 2006). In the present study, we investigate whether placement errors of third person singular OCLs may be due to cross-linguistic influence. We exposed successive (L1 French/L2 Italian and L1 Italian/L2 French) and simultaneous (2L1 Italian/French) Placement errors of object clitics (OCL) in French have been documented in 2L1 and L2 but not in L1 acquisition (Granfeldt, 2012; Hamann & Belletti, 2006).

Factors influencing the effect of pilot-injection on main-injection combustion were investigated using heat release analysis in a heavy-duty diesel engine fuelled with standard diesel fuel, and included the effect of those factors on engine performance and emissions.Combinations of pilot injection parameters i.e. pilot start of injection, pilot mass, pilot-main injection separation, and rail press
Sorption isotherms describe the relation between the equilibrium moisture content of a material and the ambient relative humidity. Most materials exhibits sorption hysteresis, that is, desorption give higher equilibrium moisture contents than absorption at equal ambient climate conditions. Sorption hysteresis is commonly evaluated by determination of an absorption isotherm followed by desorption sSorption isotherms describe the relation between the equilibrium moisture content of a material and the ambient relative humidity.

A first lesson in physical chemistry invariably starts with an example of water existing in three states, or phases - gaseous (water vapour), liquid (water from the tap) and solid (ice cubes). Such phase transitions are easily observed, but their underlying cause is not so evident. Atoms and molecules are difficult to follow due to their minute size and rapid movements. So, in order to investigateThe effect of microscopic colloid interactions on the resultant macroscopic phase behaviour is a frequently studied topic in soft matter resarch, and lies at the heart of this thesis. Key structural and dynamic properties of colloidal model systems across liquid-solid transitions are tracked using optical imaging techniques. The first studied system comprises of thermosensitive microgels. These ar
Cutting-edge technology needs small, ultrafast devices, operational in a wide range of regimes. This calls for solids with novel, unconventional and tailorable properties. Great progress is expected from materials in which electron-electron and electron-phonon correlations strongly affect the dynamics ( i.e. "unforeseen" useful properties are expected to be most likely found in systems with comple
Popular Abstract in Swedish Aerob kapacitet, i dagligt tal konditionen, är den maximala förmågan att utföra ett fysiskt arbete karaktäriserat av den maximala syreförbrukningen (V'O2max). Detta maximala arbete kan endast utföras en begränsad tid, till stor del beroende på en tilltagande anaerob metabolism, vilken bl.a. avspeglas som en ökning av utvädrat CO2 i lungorna. Längre tids arbete kan emellDifferent methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. Comparison of the rating with an exercise test in a group of women revealed that a correction based on age more accurately predicted the maximal exercise capacity. An

It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles. Ferrets, decerebrated rostral to the superior colliculus and the red nucleus, were trained in a classical condit
Popular Abstract in Swedish Graviditetsdiabetes (GDM) definieras som nedsatt glukostolerans av varierande svårighets¬grad som upptäcks under graviditet och som oftast försvinner efter förlossning. GDM innebär ökad risk för såväl moder som barn. Kvinnor med GDM föder ofta stora barn och har ökad risk för komplikationer i samband med förlossningen.

Impaired beta-cell function and insulin resistance are the hallmarks of GDM. The overall aim of this thesis was to study the genetic and immunological risk factors that increase susceptibility to GDM. First, we investigated whether autoimmuni
