Gamow -Teller Beta Decay in Drip Line Nuclei

Before radioactive ion beams became available, the Gamow-Teller (GT) giant resonance was studied using charge-exchange reactions such as (p,n) and (He,t). In beta-stable nuclei, which can be used as targets, the GT giant resonance lies above the ground state of the mother nucleus. In this thesis the GT strength distribution is studied for deformed proton drip line nuclei with 28 < Z < 72. For thes

The butterfly plant arms-race escalated by gene and genome duplications

Coevolutionary interactions are thought to have spurred the evolution of key innovations and driven the diversification of much of life on Earth. However, the genetic and evolutionary basis of the innovations that facilitate such interactions remains poorly understood. We examined the coevolutionary interactions between plants (Brassicales) and butterflies (Pieridae), and uncovered evidence for an

Numerical Methods for Conceptual Structural Design

Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings geometry, massing, and overall form are usually made during the first phase. Considering structural performance requirements during conceptual design enhances interdisciplinary interac

Comorbidity in rheumatoid arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory condition, which is associated with an increased risk of comorbidity from other diseases. RA disease severity is a major predictor of development of cardiovascular disease, serious infections and malignant lymphoma. This reflects the role of chronic inflammation in the underlying pathology. Recent surveys indicate that although clinical outcomes

Environmental cadmium and lead exposure and anti-Müllerian hormone in pregnant women

BACKGROUND: Anti-Müllerian Hormone (AMH) has been suggested as a marker for ovarian function. Cadmium and lead have been suggested to reduce female fecundity. In this study we aimed to investigate whether environmental exposure to cadmium and lead was associated with alterations in serum-AMH.MATERIALS AND METHOD: The associations between serum-AMH and whole blood cadmium or lead were investigated

Do Associations Between Perceived Environmental and Individual Characteristics and Walking Limitations Depend on Lower Extremity Performance Level?

OBJECTIVE: The aim of this study was to analyze whether the associations between perceived environmental and individual characteristics and perceived walking limitations in older people differ between those with intact and those with poorer lower extremity performance.METHOD: Persons aged 75 to 90 (N= 834) participated in interviews and performance tests in their homes. Standard questionnaires wer

Från påskdop till vardagsdop : Om en obemärkt revolution

The codification of canon law in the twelfth and thirteenth centuries occurred at the same time as important changes in pastoral practice. This article deals with changes in the practice of baptism that are tied to changes in canonical regulations.Canon law makes a fundamental distinction between solemn baptism and emergency baptism. While emergency baptisms could take place anywhere and at any ti

An Experimental Investigation on Inclined Negatively Buoyant Jets

An experimental study was performed to investigate the behavior of inclined negatively buoyant jets. Such jets arise when brine is discharged from desalination plants. A turbulent jet with a specific salinity was discharged through a circular nozzle at an angle to the horizontal into a tank with fresh water and the spatial evolution of the jet was recorded. Four different initial jet parameters we

Organisation

Organisation är en grundläggande lärobok i organisationsteori. Boken behandlar centrala områden inom organisationsteorin, bland annat arbete, personal, design, teknologi, makt, kultur, identitet och ledarskap. Ämnet ramas in och presenteras i tre delar – Människan, Struktur och Styrning – med begreppet effektivitet som genomgående tema. Boken har tre övergripande syften:1. Att presentera organisat

Influence of surface roughening on indentation behavior of thin copper coatings using a molecular dynamics approach

The structure of interest consists of a nanometer thin copper coating, resting on an infinitely stiff substrate and subjected to nanoindentation by a rigid diamond indenter. The elastic and plastic properties of the coating are investigated for different surface roughening position of attack by the indenter using molecular dynamics. The force-displacement curves, the lattice disorders and the stre

Antenna Current Optimization using MATLAB and CVX

Antenna current optimization is a tool that offers many possibilities in antenna technology. Optimal currents are determined in the antenna design region and used for physical understanding, as a priori estimates of the possibilities todesign antennas, physical bounds and as figures of merits for antenna designs. Antenna current optimization is particularly useful for small antennas and antennas t

Prognostic instrument for survival outcome in melanoma patients : based on data from the population-based Swedish Melanoma Register

BACKGROUND: Several major analyses have identified a consistent set of independent risk factors for cutaneous malignant melanoma (CMM). A few prognostic models have been presented but some are based on a limited number of patients and others are based on selected groups of patients referred to major institutions. No nationwide population-based prognostic instrument for survival of CMM has been pre

Novel Approach to Controlled Surface Modification in Textile Via Magnetic Cross- Linked Enzyme Aggregates (Clea)

In this proceeding, architecting novel magnetic Cross-Linked-Enzyme-Aggregates (CLEA)nanoparticles to effectively and controllably modify textile surfaces without damaging the fabric itself, will bediscussed. The efficiency is due to exponentially increased surface concentration of biocatalyst and to thechoice of aggregate size which controls the penetration depth and hence preventing the fabric d

A Nested Case-Control Study of Metabolically Defined Body Size Phenotypes and Risk of Colorectal Cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

BACKGROUND: Obesity is positively associated with colorectal cancer. Recently, body size subtypes categorised by the prevalence of hyperinsulinaemia have been defined, and metabolically healthy overweight/obese individuals (without hyperinsulinaemia) have been suggested to be at lower risk of cardiovascular disease than their metabolically unhealthy (hyperinsulinaemic) overweight/obese counterpart

Design of a compact varied-line space grating monochromator for enhanced flux at MAXLAB

For soft x-ray fluorescence spectroscopy with selective energy excitation, it is desirable to have maximum flux at moderate resolution. A plane grating monochromator with varied line spacing can be used in the convergent beam of an ellipsoidal focusing mirror to provide moderate resolution with a large collection angle and minimum number of reflecting surfaces. We determine the design parameters f

Observation of a low-binding-energy peak in the 2p core-level photoemission from oxidized Al(111)

High-resolution photoemission studies of oxidation of the Al(111) surface have been performed. The appearance of a component at lower binding energy than the metallic bulk Al emission in the Al 2p spectrum at oxygen exposures above ∼50 langmuir (1 L = 10-6 Torr s) is argued to be due to Al atoms which do not bond directly to oxygen atoms at the oxide-metal interface. Low-energy electron diffractio
