Growth from a straight crack subjected to arbirtrary remote loading

Growth from straight cracks is studied, both for loading in pure mode I or II and for mixed mode loading. Small scale yielding and a plane condition are assumed. Growth is assumed to take place in either mode I or mode II. Loss of directional stability sometimes occurs even from cracks that seem destined for continued growth straight forward. A striking example is the case of collinear cracks unde

On the relation between optimal wideband matching and scattering of spherical waves

Abstract in UndeterminedUsing an exact circuit analogy for the scattering ofvector spherical waves, it is shown how the problem of determiningthe optimal scattering bounds for a homogeneous spherein its high-contrast limit is identical to the closely related, andyet very different problem of finding the broadband tuning limitsof the spherical waves. Using integral relations similar to Fano’sbroadb

Expression of a novel missense mutation found in the A4GALT gene of Amish individuals with the p phenotype.

BACKGROUND: The rare p phenotype is found at a higher frequency in Amish people than in other populations. Different mutations in the 4-alpha-galactosyltransferase gene (A4GALT), responsible for synthesis of P(k) (Gb(3)) antigen, have been found to cause the P(k)-deficient p phenotype. The aim of this study was to explore the molecular background of the p phenotype in people of Amish origin. STUDY

Gene expression analysis in induced sputum from welders with and without airway-related symptoms.

PURPOSE: To identify changes in gene expression in the airways among welders, with and without lower airway symptoms, working in black steel. METHODS: Included were 25 male, non-smoking welders. Each welder was sampled twice; before exposure (after vacation), and after 1 month of exposure. From the welders (14 symptomatic, of whom 7 had asthma-like symptoms), RNA from induced sputum was obtained f

Uplink power-based admission control in multi-cell WCDMA networks with heterogeneous traffic

Wideband code division multiple access (WCDMA) is an interference-limited system. When the system operates at nearly full capacity, admitting another user may affect the stability of the system. Therefore, proper Call Admission Control (CAC) is crucial and should balance between Quality of Service (QoS) requirements for the new user and also for the existing users and at the same time keep the acc

Creating the Creative Post-political Citizen? The Showroom as an Arena for Creativity

The aim of this article is to give a tentative illustration of how a creative, postpolitical citizen is imagined and encouraged to unfold within the frame of a city renewal project. As a starting point, the article outlines an exploratory framework structured through the analytical concept of postpolis. Postpolis is a term that offers an illustration of the distinguishing qualities of contemporary

Translating sustainability: the role of the retail store

Purpose: Retailers are facing pressure to promote sustainable consumption. Building on literature about the role of retailers as “translators” of the sustainability discourse, this article studies how retailers cope with this pressure. Design/methodology/approach: This study focuses on the Swedish retail sector. In twenty-two interviews with retail representatives and thirteen store observations

Population-based study of lung function and incidence of heart failure hospitalisations.

BACKGROUND: Reduced forced expiratory volume (FEV(1)) and forced vital capacity (FVC) are risk factors for myocardial infarction (MI) and stroke. However, the relationship with incidence of heart failure (HF) is incompletely known. This population-based study explored whether reduced FEV(1) or FVC is associated with the incidence of hospitalisation for HF. METHODS: 20 998 men (mean age 43 years) w

Cerebral white matter lesions - associations with Aβ isoforms and amyloid PET.

Small vessel disease (SVD) and amyloid deposition may promote each other, with a potential association between SVD and altered production or clearance of β-amyloid (Aβ) affecting its cleavage products. We investigated the relationship between SVD, multiple isoforms of Aβ in cerebrospinal fluid (CSF) and cortical Aβ in 831 subjects with cognitive performance ranging from normal to Alzheimer's disea

Beginnings in North Sámi

In North Sámi, inceptives can be formed with the inceptive verb álgit, with the morphologically bound form -goahtit, or by changing the theme vowel of the base verb. The syntactic properties of these inceptives indicate that -goahtit is an auxiliary, and so is álgit when it takes a verbal complement. These inceptive auxiliaries are located below tense, and also below obligational and permissive mo
