Headspace fingerprint as a potential multivariate intrinsic indicator to monitor temperature variation of thermal in-pack processes: A case-study on broccoli puree KU Leuven
The aim of the presented study was to evaluate the potential of a headspace fingerprint as a multivariate intrinsic indicator for monitoring temperature history variation that can occur, for example, during in-pack food processing at the product level. Using solid-phase micro-extraction gas chromatography mass spectrometry (SPME-GC–MS), we monitored the extracted volatile fraction of a series of 8 well-defined thermally processed broccoli ...
A quantitative indicator framework for stand level evaluation and monitoring of environmentally sustainable forest management KU Leuven Universiteit Gent
An indicator framework was designed as an operational sciencebased tool for the evaluation of the environmental aspects of sustainable forest management at stand level in Flanders (Belgium). The framework aims to assess the effects of forest management on forest composition, structure and functioning. It consists of seven principles and 19 criteria, to which 157 potential indicators, selected from literature, were assigned; 40 of these were ...
Learning based Quality Indicator Aiding Heart Rate Estimation in Wrist-Worn PPG KU Leuven
Technological advancements and miniaturization of wearable sensors have enabled long-term pervasive physiological monitoring. Wrist-worn photoplethysmography (PPG) sensors, although quite popular owing to their form factor, suffer from poor signal quality in ambulatory settings due to motion artifacts. This affects the reliable estimation of vital cardiac parameters, especially during motion/activities of daily living. Hence, in this paper, we ...
The use of effective carbon rates as an indicator for climate mitigation KU Leuven
In 2016, the Organisation for Economic Co-operation and Development (OECD) introduced the effective carbon rate (ECR). This innovative indicator measures the combined price put on carbon emissions by energy taxes and emissions trading schemes. In this chapter, we first calculate the national weighted average ECR for a selection of case countries (which is not provided by the OECD), including China, the US, Japan, the UK, France, Germany and ...
Urinary CC16, a potential indicator of lung integrity and inflammation, increases in children after short-term exposure to PM2.5/PM10 and is driven by the CC16 38GG genotype KU Leuven Universiteit Hasselt
Particular matter (PM) exposure is a big hazard for public health, especially for children. Serum CC16 is a well-known biomarker of respiratory health. Urinary CC16 (U-CC16) can be a noninvasive alternative, albeit requiring adequate adjustment for renal handling. Moreover, the SNP CC16 G38A influences CC16 levels. This study aimed to monitor the effect of short-term PM exposure on CC16 levels, measured noninvasively in schoolchildren, using an ...
The anogenital ratio as an indicator of reproductive performance in dairy heifers Universiteit Gent
The anogenital distance (AGD) is considered a marker for prenatal androgen exposure and fertility in multiple species including humans. In dairy cattle, it is described as the length between the center of the anus and the clitoral base (AGDc). However, in other species, the distance from the center of the anus to the dorsal commissure of the vulva (AGDv) is also considered to be a predictor for fertility traits, as well as the anogenital ratio ...
Variable selection for long-term forecasting using temporal aggregation Universiteit Gent
Producing long-term forecasts is typically done by extrapolating past tendencies to the future, often adjusted with managerial insights. In several sectors such as credit insurance, investments and supply chain management tactical-strategic decisions are made based on these forecasts. External relevant market information has the potential to improve forecast accuracy. However, long-term movements can be overwhelmed by the short-term dynamics. ...
Guidelines based on life cycle assessment for solvent selection during the process design and evaluation of treatment alternatives KU Leuven
The aim of this paper is to develop guidelines in order to assist in decision making with respect to treatment options of waste solvents, and more importantly for the choice of solvent in the design of the process a priori, from an environmental point of view based on the composition of a mixture. Life cycle assessment (LCA) was used to evaluate two treatment alternatives: continuous distillation and incineration. The software Ecosolvent® ...
Target-Driven Positive Selection at Hot Spots of Scorpion Toxins Uncovers Their Potential in Design of Insecticides KU Leuven
Positive selection sites (PSSs), a class of amino acid sites with an excess of nonsynonymous to synonymous substitutions, are indicators of adaptive molecular evolution and have been detected in many protein families involved in a diversity of biological processes by statistical approaches. However, few studies are conducted to evaluate their functional significance and the driving force behind the evolution (i.e., agent of selection). Scorpion ...
