Near-Ultraviolet Observations of HD 221170: New Insights into the Nature of r-Process-rich Stars

Employing high-resolution spectra obtained with the near-UV-sensitive detector on the Keck I HIRES, supplemented by data obtained with the McDonald Observatory 2d-coudé, we have performed a comprehensive chemical composition analysis of the bright r-process-rich metal-poor red giant star HD 221170. Analysis of 57 individual neutral and ionized species yielded abundances for a total of 46 elements

The importance of CTLA-4 polymorphism and human leukocyte antigen genotype for the induction of diabetes-associated cytokine response in healthy school children.

Type 1 diabetes (T1D) is an autoimmune disease associated with the destruction of pancreatic β cells and genetically linked to human leukocyte antigen (HLA) class II DR3-DQ2 and DR4-DQ8 haplotypes. The +49A/G polymorphism of the immunoregulatory cytotoxic T-lymphocyte antigen 4 (CTLA-4) gene is also associated with T1D. Genetic and environmental risk factors precede the onset of T1D, which is char

Copyrights and wrongs

Abstract in UndeterminedThe digital age has brought with it advantages and disadvantages. Few would deny the benefit of being able to store entire song collections on pocket-sized MP3 players. Fewer still would disregard the merits of grandparents in Sydney being able to have face-to-face conversations with grandchildren in Berlin.Certain problems however, have also developed. The music and film i

Local risk analysis

Two storms in Sweden 2005 and 2007 clarified both professional crisis managers and citizens' ability to respond to the consequences. These events created an awareness of the vulnerability of society, especially in rural areas. Emergent Citizen Groups (ECG) conducted initially a large part of crisis management, such as clearing roads, supporting exposed neighbors and repairing power lines in collab

Feature transition charts for visualization of cross-project scope evolution in large-scale requirements engineering for product lines

In large-scale multi-project software engineering it is a challenge to provide a comprehensive overview of the complexity and dynamics of the requirements engineering process. This paper presents a visualization technique called Feature Transition Charts (FTC) that gives an overview of scoping decisions involving changes across multiple projects based on previous work on within-project visualizati

Two configurational approaches on the modelling of continuum dislocation inelasticity

The main focus of this contribution consists in the elaboration of a continuum modelling approach accounting for dislocation-based quantities. Related deformation dependent history-variables are attached to individual material points and, moreover, are extended by means of gradients thereof so that so-called weak non-localities are captured. These gradients of internal variables may be further spe
