Experimental study of thermal breakdown products from halogenated extinguishing agents

Thermal breakdown products from four different fire extinguishing agents have been analysed. The agents studied were: bromotrifluoromethane (Halon 1301), pentafluoroethane (HFC 125), heptafluoropropane (HFC 227ea) and dodecafluoro-2-methyl-pentane-3-one (C6F-ketone). In the tests, the studied agent was introduced into a propane flame in a diffusion flame burner. The combustion products were analys

Screening-preventable cervical cancer risks: Evidence from a nationwide audit in Sweden

Background The effectiveness of cervical cancer screening programs differs widely in different populations. The reasons for these differences are unclear. Routine and comprehensive audits have been proposed as an ethically required component of screening. We performed a nationwide audit of the effectiveness of the Swedish cervical cancer screening program. Methods We identified all invasive cervic

Candida albicans Uses the Surface Protein Gpm1 to Attach to Human Endothelial Cells and to Keratinocytes via the Adhesive Protein Vitronectin.

Candida albicans is a major cause of invasive fungal infections worldwide. Upon infection and when in contact with human plasma as well as body fluids the fungus is challenged by the activated complement system a central part of the human innate immune response. C. albicans controls and evades host complement attack by binding several human complement regulators like Factor H, Factor H-like protei

Society-nature coevolution: interdisciplinary concept for sustainability

A brief historical background to the currently ascend- ing interest in evolutionary and coevolutionary theory is sketched, and the concept of society–nature coevolution is positioned in this broader field. The significance of society–nature coevolution- ary pathways for transition to sustainability is highlighted with Schellnhuber’s heuristic ‘theater world’ for representing paradigms of sustainab

Guaranteed Cost Control Design for Delayed Teleoperation Systems

A procedure for guaranteed cost control design of delayed linear bilateral teleoperation systems with nonlinear external forces is proposed. The assumption that the external forces are nonlinear functions of velocities and/or positions of local devices, and one part of these forces satisfies a sector condition has been made. A virtual tool system is introduced to 'observe' the forces at the remote

Supporting Visual Editors using Reference Attributed Grammars

Reference attributed grammars (RAGs) extend Knuth’s attribute grammars with references. These references can be used to extend the abstract syntax tree to a graph. We investigate how RAGs can be used for implementing tools for visual languages. Programs in those languages can often be expressed as graphs.

Testicular-cancer survivors experience compromised language following chemotherapy: Findings in a Swedish population-based study 3-26 years after treatment

Background. Studies suggest an increased risk for compromised cognitive function among cancer survivors. It is unclear to what extent chemotherapy is the cause and how the dysfunction, when present, affects everyday life. The objective was to study self-reported behaviours that may depend on cognitive function, among testicular-cancer survivors who received various cycles of cisplatin-based chemot

Measurement of the cross section for the production of a W boson in association with b-jets in pp collisions at root s=7 TeV with the ATLAS detector

A measurement is presented of the cross section for the production of a W boson with one or two jets, of which at least one must be a b-jet, in pp collisions at root s = 7 TeV. Production via top decay is not included in the signal definition. The measurement is based on 35 pb(-1) of data collected with the ATLAS detector at the LHC. The W + b-jet cross section is defined for jets reconstructed wi

Kanon och kulturarv : Historia och samtid i Danmark och Sverige

Kanon och kulturarv har diskuterats intensivt de senaste åren i Danmark och Sverige. I Danmark har regeringens beslut att definiera en dansk kanon väckt stor debatt. I Sverige har diskussionen varit hovsammare samtidigt som ordet kulturarv har ett starkt grepp om museer, kulturmiljövård och arkiv. I Danmark har diskussionen kretsat kring vad som är danskt, vem som ska definiera danskheten och vil

Novel genetic variants in differentiated thyroid cancer and assessment of the cumulative risk.

A genome-wide association study (GWAS) performed on a high-incidence Italian population followed by replications on low-incidence cohorts suggested a strong association of differentiated thyroid cancer (DTC) with single nucleotide polymorphisms (SNPs) at 9q22.33, 2q35, 20q11.22-q12 and 14q24.3. Moreover, six additional susceptibility loci were associated with the disease only among Italians. The p

Optimizing cropland cover for stable food production in Sub-Saharan Africa using simulated yield and Modern Portfolio Theory

Food security can be defined as stable access to food of good nutritional quality. In Sub Saharan Africa access to food is strongly linked to local food production and the capacity to generate enough calories to sustain the local population. Therefore it is important in these regions to generate not only sufficiently high yields but also to reduce interannual variability in food production. Tradit

Case management for frail older people - a qualitative study of receivers' and providers' experiences of a complex intervention.

Case management interventions have been widely used in the care of frail older people. Such interventions often contain components that may act both independently of each other and interdependently, which makes them complex and challenging to evaluate. Qualitative research is needed for complex interventions to explore barriers and facilitators, and to understand the intervention's components. The

Considering rigor and relevance when evaluating test driven development: A systematic review

Context: Test driven development (TDD) has been extensively researched and compared to traditional approaches (test last development, TLD). Existing literature reviews show varying results for TDD. Objective: This study investigates how the conclusions of existing literature reviews change when taking two study quality dimension into account, namely rigor and relevance. Method: In this study a sys
