Development of full-scale façade tests in ISO TC92

During the 90ies, ISO TC92 SC1 started the development of full-scale tests for facades based upon an international review. The work resulted in two standards namely ISO 13785 part 1 and part 2. The work was performed in WG7 and a substantial input from international experts was given. The paper gives a short historical update on the development but also includes a short overview of the major type

Challenges in determining critical mass flux for ignition

Traditionally in fire modelling, a solid fuel has been assumed to ignite when the solids surface reaches a specific temperature or when the heat flux upon the solid reaches a critical level. Although these approaches of determining ignition for the condensed phase are practical, ignoring the gas phase conditions may lead to incorrect assumptions regarding material safety. A more 'physical' explana

Fire safety in military vehicles evaluation of ISO 3795

It has been shown in previous studies that the current standard used to fire test interior materials in civilian and military vehicles, ISO 3795 (FMVSS 302), has led to a low level of fire safety of interior materials in civilian vehicles. The purpose of this study was to evaluate the fire safety of interior materials in military vehicles. The aim was to suggest a fire test method to be used on in

Longitudinal and cross-sectional variability in markers of joint metabolism in patients with knee pain and articular cartilage abnormalities

Objective: To determine the within- and between-patient variability in the concentrations of synovial fluid, serum and urine markers of joint tissue metabolism in a cohort of patients with knee pain and cartilage changes consistent with early-stage knee osteoarthritis. Design: Samples of synovial fluid, serum, and urine were obtained from 52 patients on eight different occasions during 1 year, as

WOMAC Osteoarthritis Index - Additional dimensions for use in subjects with post-traumatic osteoarthritis of the knee

Objective: To compare the sensitivity of WOMAC and the two added dimensions Sport and Recreation Function and Knee Related Quality of Life in subjects with radiographic knee OA to that in controls. To study the influence of age on the reported outcomes. Design: Outcomes were compared between subjects having had meniscectomy 21 years ago and which at time of follow-up had definite radiographic OA (

What are the outcomes after joint replacement?

Total hip replacement (THR) is an effective intervention with a good cost/benefit ratio. Worldwide, each year it brings relief in the form of improved function and decreased pain to at least half a million patients with severe osteoarthritis (OA). Since the introduction by Charnley more than 30 years ago, the basic concept remains much the same, but with a multitude of changes in details of surgic

Background: Osteoarthritis (OA) is the most common joint disease encountered throughout Europe. A task force for the EULAR standing committee for clinical trials met in 1998 to determine the methodological and logistical approach required for the development of evidence-based guidelines for treatment of knee OA. The guidelines were restricted to cover all currently available therapies for knee OA

Manufacturing backshoring : a systematic literature review

The purpose of this research is to review and analyze in a systematic manner the current research published in peer-reviewed international scientific journals on the backshoring of manufacturing. We identify 20 articles published from 2009 to early 2016. We classify and discuss the literature according to publication year, research methodology, industry type, and firm size. Using content analysis,

Variable residence time-based model for BOD removal in free-water surface wetlands

Constructed wetlands have been increasingly used for treatment of secondary wastewater containing various contaminants. This paper presents a Variable Residence Time (VART)-based model, called VART-BOD model, for simulation of BOD removal processes in constructed wetlands with free water surface (FWS). Mathematically, the VART-BOD model describes a free water surface wetland with three vertical la

Improving the mix of institutional and community care for older people with dementia : an application of the balance of care approach in eight European countries

Objectives: To examine whether the mix of community and institutional long-term care (ILTC) for people with dementia (PwD) in Europe could be improved; assess the economic consequences of providing alternative services for particular groups of ILTC entrants and explore the transnational application of the ‘Balance of Care’ (BoC) approach. Method: A BoC study was undertaken in Estonia, Finland, Fra

Bumblebees perform well-controlled landings in dim light

To make a smooth touchdown when landing, an insect must be able to reliably control its approach speed as well as its body and leg position—behaviors that are thought to be regulated primarily by visual information. Bumblebees forage and land under a broad range of light intensities and while their behavior during the final moments of landing has been described in detail in bright light, little is

Enhancing the productivity of the bi-enzymatic convergent cascade for ɛ-caprolactone synthesis through design of experiments and a biphasic system

A two-step Design of Experiments (DoE) strategy followed by a two-liquid-phase system (2LPS) was applied to enhance the ɛ-caprolactone yield in the cyclohexanone monooxygenase (CHMO)-alcohol dehydrogenase (ADH) convergent cascade system. The key reaction parameters were identified and optimized for the determination of an optimal operational window for the aqueous media. In the 2LPS system, high p
