District heating networks are very common energy systems all over the world but only few studies have been carried out to assess their performances through quality indicators. These indicators express district heating performances through different points of view. Four ones are developed in this study: energy sources, efficiencies, heat delivering equipments characteristics and environmental efficiency as a sum up. First, the only energy indicator generally used is the primary energy factor (PEF), which quantifies the primary energy use of a device. However it does not give a complete insight of the whole energy use of district heating networks. Two other parameters have to be stated for this purpose: primary energy efficiency and the energy share. Second, district heating efficiencies are generally not been taken into account unless sometimes the only amount of heat losses. A first indicator is defined to quantify networks heat losses relatively to the amount of heat delivered to customers. To take heat plant efficiencies into account, a more global indicator is defined. Its definition is close to a seasonal efficiency and it permits comparisons with other heating systems. Third, indicators have been defined for heat plants equipments. Their aim is to permit stakeholders to check networks management of district heating companies. Two indicators are defined: one measures subscripted power relatively to network length and the other one represents the fictitious number of plants working hours while maximum plants power was delivered all the year. Finally, environmental efficiency is stated. This analysis can include different aspects: green house gas emissions, water use and other pollutants emissions. For both design and management of district heating networks, an indicator representing CO2 emissions appears to be the most suitable one. Expressed relatively to delivered energy, it can be seen as a sum up of previous indicators because result of bad performances increases these emissions. In this paper, these eight indicators are defined and their use is highlighted by a comparison of four different Finnish district heating networks. [less ▲]

A colour machine vision system was developed to form a basis for colour grading and defect inspection of 'Golden delicious' apples. The criteria were based on European Union standards and took into account commercial practices which add subclasses to the basic categories. The system was able to grade correctly more than 90% of the apple for colour (94% by using three colorimetric parameter R, G, B or H,S,I and 91% by using the single canonical variate) and ensured good defect detection (russet, scab, fungi attack, tec.).

This paper analyses the quality of collaboration of two student teams in a longitudinal study of a collaborative distant architectural studio. Based on a simple method to assess several dimensions of this quality of collaboration, we compared the two groups at three stages of the design process. We also analysed how the quality of collaboration evolved over time and as a function of the design stage. We finally discuss the interests of the method and some insights to support a better understanding of mechanisms of collaboration. [less ▲]

Objectives To examine the evolution of quality of life (QOL) in demented subjects at base-line, one and 2 years later and to determine clinical variables associated with QOL. Method Longitudinal study of a cohort of 127 subjects living at home or in a long-term care institution. A QOL measure (Alzheimer Disease Related Quality of Life; ADRQL) was administered three times. In addition, several clinical instruments (MMSE, IADL, ADL and CDR/M) were also administered. Results ADRQL data analysis did not reveal significant modifications of QOL over the 2-year period, whereas results from clinical instruments showed a significant deterioration. On the group, the variations of ADRQL scores were limited, with some improvement after the first year followed by some deterioration after the second year. On the other hand, ADRQL scores fluctuated every year by at least 10 points for more than 50% of subjects. With dementia evolution, it was observed that the clinical variables were more strongly correlated with ADRQL scores and were more significant predictors. This varied from 5.9% (MMSE) in 2002 to 40.01 % in 2004 (MMSE and CDR/M). Conclusions QOL did not develop in a strictly linear manner following the deterioration of clinical state. This suggests that the evolution of QOL is also determined by other variables relating to the physical and social environment of the patients. Their role seems particularly important for the mild to moderate stages of dementia. Copyright (c) 2007 John Wiley [less ▲]

OBJECTIVES: To assess the sensitivity of the 'Alzheimer's Disease Related Quality of Life' instrument (ADRQL) applied to Belgian people with dementia (n = 357), mild cognitive impairment (MCI) (n = 36), and controls (n = 72). We also determined the clinical parameters that influence the quality of life (QOL) of people with dementia. METHOD: Each subject was evaluated with the ADRQL, the Mini Mental State Examination (MMSE), the cognitive scale of the Cambridge Examination for Mental Disorders of the Elderly (CAMCOG), the Katz's ADL classification (ADL), the Instrumental Activities of Daily Living (IADL), the Behavior Rating Scale for Dementia (CERAD/BRSD), and the Clinical Dementia Rating/Modified (CDR-M). RESULTS: The ADRQL showed that QOL of the dementia group (65.77 +/- 17.04) was significantly inferior to that of the MCI (82.11 +/- 13.31) and control groups (79.75 +/- 15.82). There were no significant differences between the MCI and control groups. Within the dementia group, the five ADRQL subscale results were similar to those reported in other studies. Gender, age and place of residence had no significant influence on ADRQL scores. In contrast, ADRQL scores correlated significantly with MMSE, CAMCOG, IADL, ADL, CERAD/BRSD, and CDR-M. The MMSE and CERAD/BRSD were significant predictors of ADRQL variability. CONCLUSIONS: QOL of people with dementia is inferior to that of people with MCI and controls. This demonstrates the ADRQL instrument is sufficiently sensitive for evaluating the QOL of people with dementia. Longitudinal studies are needed to specifically examine the rate of QOL evolution throughout the entire dementia process. Copyright (c) 2008 John Wiley [less ▲]

The reduced muscle mass and impaired muscle performance that define sarcopenia in older individuals are associated with increased risk of physical limitation and a variety of chronic diseases. They may also contribute to clinical frailty. A gradual erosion of quality of life (QoL) has been evidenced in these individuals, although much of this research has been done using generic QoL instruments, particularly the SF-36, which may not be ideal in older populations with significant comorbidities. This review and report of an expert meeting presents the current definitions of these geriatric syndromes (sarcopenia and frailty). It then briefly summarizes QoL concepts and specificities in older populations and examines the relevant domains of QoL and what is known concerning QoL decline with these conditions. It calls for a clearer definition of the construct of disability, argues that a disease-specific QoL instrumentfor sarcopenia/frailty would be an asset for future research, and discusses whether there are available and validated components that could be used to this end and whether the psychometric properties of these instruments are sufficiently tested. It calls also for an approach using utility weighting to provide some cost estimates and suggests that a time trade-off study could be appropriate. [less ▲]
