Ionization by pH and Anionic Surfactant Binding Gives the Same Thickening Effects of Crosslinked Polyacrylic Acid Derivatives

Physical properties of aqueous solutions of hydrophobically modified crosslinked polyacrylic acids change quite extensively as the polymer is charged up. A study is carried out concerning the similarities between two polymer ionization processes, that is, by pH increment and anionic surfactant addition. The two processes charge the polymer by distinctly different mechanisms. At sufficiently high p

On the mechanisms that limit oxygen uptake during exercise in acute and chronic hypoxia: role of muscle mass

Peak aerobic power in humans ((V) over dot(O2), peak) is markedly affected by inspired O-2 tension (F-IO2). The question to be answered in this study is what factor plays a major role in the limitation of muscle peak. (V) over dot(O2) in hypoxia: arterial O-2 partial pressure (P-a,(O2)) or O-2 content (C-a,C-O2)? Thus, cardiac output (dye dilution with Cardio-green), leg blood flow (thermodilution

Identification and energy calibration of hadronically decaying tau leptons with the ATLAS experiment in pp collisions at root s=8 TeV

This paper describes the trigger and offline reconstruction, identification and energy calibration algorithms for hadronic decays of tau leptons employed for the data collected from pp collisions in 2012 with the ATLAS detector at the LHC center-of-mass energy root s = 8 TeV. The performance of these algorithms is measured in most cases with Z decays to tau leptons using the full 2012 dataset, cor

Contact allergy to formaldehyde. Diagnosis and clinical relevance.

Preservatives are biologically active substances mainly used in water-based products to prevent the growth of microorganisms. Most people are exposed to them on a daily basis. Formaldehyde is one of the oldest and most commonly used preservatives. However, it is a well-known contact sensitiser in dermatitis patients. The aims of this work were: i) to investigate the prevalence of contact allergy t

Ancillary findings assessed by ventilation/perfusion tomography. Impact and clinical outcome in patients with suspected pulmonary embolism.

Ventilation/perfusion tomography (V/P SPECT) is a recommended method for diagnosing and follow-up of pulmonary embolism (PE). Moreover, it is possible to recognize other pathologies in addition to PE, such as pneumonia, COPD and left heart failure (LHF). The objective of this prospective study was to identify frequency of ancillary findings among patients with suspected PE. Patients, material, met

Photoproduction of J/psi and of high mass e(+)e(-) in ultra-peripheral Au plus Au collisions at root s(NN)=200 GeV

We present the first measurement of photoproduction of J/psi and of two-photon production of high-mass e(+)e(-) pairs in electromagnetic (or ultra-peripheral) nucleus-nucleus interactions, using Au + Au data at root s(NN) = 200 GeV. The events are tagged with forward neutrons emitted following Coulomb excitation of one or both Au* nuclei. The event sample consists of 28 events with m(e+e-) > 2 GeV

Modelling Epistemic Actions in Interrogative Belief Revision

Abstract in UndeterminedInterrogative belief revision is a relatively recent framework for belief revision theory, in which the epistemic state of an agent includes a representation of that agent's research agenda, i.e. the set of questions the agent wants to have answers to. This added structure opens new possibilites for various types of epistemic change that cannot be distinguished in tradition

Making Sense of Extended Producer Responsibility: Towards a framework for policy transfer

Policy transfer of complex interventions often falls into the trap of uninformed, incomplete, and/or inappropriate transfer because the interventions are insufficiently identified with some of their perceived core components. This is no exception in the interspatial learning about extended producer responsibility (EPR) programmes. This thesis aims to transcend this shorthand approach to policy tra

Generation of Regionally Specified Neural Progenitors and Functional Neurons from Human Embryonic Stem Cells under Defined Conditions.

To model human neural-cell-fate specification and to provide cells for regenerative therapies, we have developed a method to generate human neural progenitors and neurons from human embryonic stem cells, which recapitulates human fetal brain development. Through the addition of a small molecule that activates canonical WNT signaling, we induced rapid and efficient dose-dependent specification of r

Social Construction of Technical Aids - Personal Meaning and Interactional Effects of Disability and Assistive Devices in Everyday Life

This thesis concerns the role of disability and assistive devices in everyday life among persons with, for instance, impairments related to mobility (e.g. wheelchair users) and bodily shape and configuration (e.g. dysmelia). Assistive devices are seen as both includators (assisting participation and emancipation) and excludators (limiting participation, restraining empowerment, and stigmatizing).

In situ scanning electron microscopy study of fatigue crack propagation

The fatigue crack propagation rate is influenced by various mechanisms at the very vicinity of the crack tip, e.g., local plasticity and/or creep, microcracking, crack branching, and crack closure induced by plasticity and roughness. To study these mechanisms and their influence on crack propagation rate during different loadings, in situ scanning electron microscope studies have been performed. T

Challenging disparities in capacity development for disaster risk reduction

Although capacity development has been identified as the means to substantially reduce global disaster losses, it is a challenge for external partners to facilitate the development of sustainable capacities for disaster risk reduction in disaster-prone countries. The purpose of this study is to investigate potential gaps between how leading professionals approach such capacity development and guid

SEFAS The Self-Reported Foot and Ankle Score

Background: Patient-reported outcome (PRO) instruments are used in all medical disciplines to evaluate patients with different diseases and also to follow results after treatments such as surgery. Currently there is no generally accepted and fully validated PRO instrument for the foot and ankle. Aims: To translate the New Zealand Ankle Questionnaire into a Swedish version, [the Self-Reported Foot

Screening of women for intimate partner violence: a pilot intervention at an outpatient department in Tanzania

Intimate partner violence (IPV) is a public health problem in Tanzania with limited health care interventions. Objectives: To study the feasibility of using an abuse screening tool for women attending an outpatient department, and describe how health care workers perceived its benefits and challenges. Methods: Prior to screening, 39 health care workers attended training on gender-based violence an

A Preclinical Model of Malignant Peripheral Nerve Sheath Tumor-like Melanoma Is Characterized by Infiltrating Mast Cells

Human melanomas exhibit considerable genetic, pathologic, and microenvironmental heterogeneity. Genetically engineered mice have successfully been used to model the genomic aberrations contributing to melanoma pathogenesis, but their ability to recapitulate the phenotypic variability of human disease and the complex interactions with the immune system have not been addressed. Here, we report the u

Sustainable analytical chemistry-more than just being green

This review article describes analytical chemistry beyond green chemistry and all efforts that contribute to a more sustainable development. A background is given on sustainable development and green chemistry. Examples of "greening" strategies for sample preparation, chromatography, and detection are given. Thereafter, the review discusses how and why a method or a solvent could be claimed as bei

Auto-antibodies and their association with clinical findings in women diagnosed with microscopic colitis.

Microscopic colitis (MC) is a disease manifested by diarrhoea and is divided into collagenous and lymphocytic colitis. The aetiology is unknown, but auto-immunity is suggested. Auto-antibodies have been only rarely examined in this entity. The aim of the study was to examine the prevalence of auto-antibodies, and to examine associations between the presence of antibodies and clinical findings.
