Aromatic fluoro amino acids such as 2-[18F]fluoro-L-tyrosine (FTYR) and 6-[18F]fluoro-L-DOPA (FDOPA) are useful radiopharmaceuticals for oncologic studies and evaluation of the presynaptic dopaminergic function using positron emission tomography. Recently, a no-carrier-added (nca) enantioselective synthesis of these compounds, based on an multistep PTC approach was automated in a FASTlabTM module from GE . From 185 GBq of [18F]fluoride and after 1 hour of synthesis, more than 37 GBq of FTYR or FDOPA are available . This automated production yields enough doses for many PET studies. A monograph for FDOPA prepared by electrophilic substitution exists , but it is not adapted to the nca nucleophilic synthesis of FDOPA and FTYR, as in this case specific activity, by products and possible impurities are different. A complete quality control (QC) has then be developed in accordance with the guidelines of the European Pharmacopeia (Eur. Ph.). [less ▲]

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 ▲]
