Doctor Marcel Leclercq was a pioneer in the field of forensic entomology. He has provided his knowledge of insect biology to many forensic cases, and most of them have found the way to publication. Most of the papers he has written were focused on individual cases, and despite the abundance of entomoforensic investigations he conducted, no synthesis has been published. This paper summarizes 36 years of forensic entomological investigations in temperate Europe, mainly in Belgium. Leclercq’s work includes 132 entomological cases involving 141 human corpses found in various death scenes. Under certain conditions, insect specimens found on death scene can provide information on when (postmortem interval estimation), where and how a person died. More or less one hundred insect species associated to a dead body have been identified by Marcel Leclercq. [less ▲]

Implementing conservation strategies needs the knowledge of relationships inside the concerned population. The aim of this study was to find tools to help scientists and breeders to manage endangered populations or populations with missing pedigree information. The animal genetics literature often seems unaware of relevant developments in human genetics (and conversely). In this study, an approach called Familial Searching was tested. This is used in forensic science, in addition to matching DNA evidence directly to criminal profiles, to search for people (present in a database) who are related to an individual that left DNA evidence at a scene of crime. This method is based on the calculation of likelihood ratios (LR) between genotype of an individual and genotypes of each other individuals of the database. In order to decrease the number of comparisons, the available pedigree information was used as ‘local’ prior information, i.e. relating to specific pairs of individuals. General knowledge about the studied population (e.g., generation interval, sexual maturity) was considered as ‘global’ prior information. Including prior information reduced the number of comparisons from over 50%. Results showed that the parents were always classified into the 4 highest LR. This method simplified parentage verifications, it allowed the detection of 90% of false parentage (LR=0). It also allowed to create new links in the pedigree through detection of unregistered parents. The method was tested on the Skyros pony, an indigenous Greek breed. For this breed, partial pedigree information was available, and 99 individuals were genotyped at 16 microsatellite loci. The method allowed to check about 2500 possible parent-child combinations, three registered parentages were considered as incorrect and one non-recorded parentage was detected. The method will now be tested on other breed and with other markers, e.g. SNPs. [less ▲]

This paper is dedicated to electricity prosumer communities, which are groups of people producing, sharing and consuming electricity locally. This paper focuses on building a rigorous mathematical framework in order to formalise sequen- tial decision making problems that may soon be encountered within electricity prosumer communities. After introducing our formalism, we propose a set of optimisation problems reflecting several types of theoretically optimal behaviours for energy exchanges between prosumers. We then discuss the advantages and disadvantages of centralised and decentralised schemes and provide illustrations of decision making strategies, allowing a prosumer community to generate more distributed electricity (compared to commonly applied strategies) by mitigating over- voltages over a low-voltage feeder. We finally investigate how to design distributed control schemes that may contribute reaching (at least partially) the objectives of the community, by resort in to machine learning techniques to extract, from centralised solution(s), decision making patterns to be applied locally. First empirical results show that, even after a post-processing phase so that it satisfies physical constraints, the learning approach still performs better than predetermined strategies targeting safety first, then cost minimisation.

In the scientific community, increasing concerns on groundwater quality and quantity have motivated the development of numerical models for groundwater management since the 1970’s. Mathematical and numerical models are, for example, promising tools for prediction of concentration and they can be used to make the dynamic link between nitrogen manure and the resulting evolution of nitrate concentration in groundwater. However, from a practical and managerial perspective, there have been very few real attempts of developing efficient calibrated and validated transport models in particular at the scale of the groundwater body, which is the management unit of groundwater resource in the European Union. Actually two main challenges remains, (1) performing numerical tools are not really available and (2) parametrisation of such transport models at the regional scale is difficult due to the large amount of data required. Generally speaking models can be grouped in different categories ranging from black box models to physically based distributed models. The black box models such as transfer function are simple but attractive because they require relatively less data but with the drawback that modelling result are not spatially distributed while the predictive capability of these models is questionable due to the semi-analytical nature of the process descriptions. On the contrary, physically based distributed model require more data but, due to a more advanced description of ongoing processes, such models are expected to have better predictive capabilities than the black box models. Black box model and physically based distributed model approaches have all proved their utilities and have all their justifications, advantages and disadvantages regarding the development of regional scale groundwater model. A new flexible methodology (the Hybrid Finite Element Mixing Cell method) has been developed that allows combining in a single model, and in a fully integrated way, different mathematical approaches of various complexities for groundwater in complex environment. This method has been implemented in the SUFTD, a finite element groundwater flow and solute transport numerical model. Combining on the one hand the use of a spatially distributed groundwater flow and solute transport model taking advantages of this Hybrid Finite Element Mixing Cell Approach method and on the other hand spatial datasets of tritium and nitrate contents, an illustration on the problem of nitrate trend assessment and forecasting for an important groundwater resource located in the Geer groundwater body (480 km²) in the Walloon Region of Belgium will be proposed.

Land cover and land use change has become a central component in current strategies for managing natural resources and in environmental change monitoring. This study aims to investigate the trend evolution of forest and pastoral areas in Rif Mountain, between 1984 and 2014, on Landsat imageries using remote sensing and GIS techniques. The forest and pastoral areas declined from about 4548 km² in 1984 to about 3588 km² by 2014, while the non-forest and non-pastoral areas increased by some 7,7% from 7912 km² in 1984 to about 8872 km² by 2014. Deforestation, expansion of agricultural lands, increase of rural population, overgrazing have been identified as the main factors that contribute to the forest and pastoral areas degradation. To ensure the sustainability of pastoral and forest resources, management and protection actions should be undertaken. [less ▲]

Central African rainforests are no longer considered as pristine, but as the outcome of a long history of changes due mainly to climatic variation. For the later part of the Holocene it has been hypothesised that climate changes together with human activities triggered modifications in terms of distribution and botanical composition. While developing a research project to explore the mechanisms of forest change, new research avenues for the archaeology of rainforests became apparent. In this paper, we outline the results of this approach, implemented on a forest concession (Cameroon). We introduce our methodology based on the analysis of botanical inventories (focused on large trees of human linked species and light demanding species), coupled to systematic core boring and test pits. A sampling strategy for the collection of charcoal and its identification is developed and archaeological remains found in association are analyzed at the Royal Museum for Central Africa. [less ▲]
