Minimal soil tillage methods, crop rotation, cover crop and continuous plant residue cover are the main pillars of sustainable agriculture. Lower energy consumption, costs and time are some direct benefits in favor to the adaptation of this agriculture. This practices aims also directly at protecting the soil from wind and water erosion by covering the soil. Lower disruption of the soil aims at developping the micro- and macro-fauna activity that increases soil fertility and carbon and nitrogen sequestration in soils. Unfortunately, some of the great constraints to the adaptation of conservation agriculture remain weed management, fungal diseases and pest management, that has been shown to be a problem in non-ploughed fields. The aim of our study is to evaluate, on a same field (Wallonia context), contrasted tillage methods for managing the cover crop and the implantation of the main crop. The following measurements were taken: germination rate, root and shoot biomass development, root notation (size and shape), leaf area index and quality of harvested product. Preliminary results indicate that the different tillage methods did not have a significant impact on crop production or development. However changes in germination dynamics were observed, the reduced tillage inducing slower germination. Regarding weeds populations, some difference were observed in weed occurrences.

Aiming at giving the students an overview of the main "Organization and Human Resources Management" practices, issues, and challenges, the "Organization and Human Resources Management" e-book is divided into 4 main chapters: 1. "Understanding the diversity of organizations" 2. "From organizational configurations to HRM models" 3. "HRM policies: internal and external consistencies" 4. "HR Function and HR Department" This e-book contains several complementary resources that will help the students in their learning process: 1. The e-book first contains in-depth explanations of the main usual "Organization Theory" notions as well as of the main current "Human Resources Management" challenges and issues. These explanations are completed by several syntheses (tables, figures, graphics, etc.) throughout the theoretical developments. 2. Videos and Podcasts are also used to introduce the content of each chapter as well as to offer complementary explanations on some key theoretical issues and complex concepts. 3. As well, students will find articles and references at the end of each chapter. This "reading portfolio" offers the students the opportunity to complete their knowledge and to deepen their understanding of the main theoretical concepts, through additional and complementary points of views. 4. Finally, several video case studies are presented throughout the theoretical explanations. These video case studies are not only practical illustrations of the concepts but are also a great opportunity for the students to concretely check out their understanding of the main theoretical concepts through real case analyses. To do so, each video case study is introduced by questions that guide the students in their watching of the videos and in their analyses of the case studies. [less ▲]

In July 2016, NASA’s Juno mission becomes the first spacecraft to enter polar orbit of Jupiter and enture deep into unexplored polar territories of the magnetosphere. Focusing on these polar regions, we review current understanding of the structure and dynamics of the magnetosphere and summarize the outstanding issues. The Juno mission profile involves (a) a several-week approach from the dawn side of Jupiter’s magnetosphere, with an orbit-insertion maneuver on July 6, 2016; (b) a 107-day capture orbit, also on the dawn flank; and (c) a series of thirty 11-day science orbits with the spacecraft flying over Jupiter’s poles and ducking under the radiation belts. We show how Juno’s view of the magnetosphere evolves over the year of science orbits. The Juno spacecraft carries a range of instruments that take particles and fields measurements, remote sensing observations of auroral emissions at UV, visible, IR and radio wavelengths, and detect microwave emission from Jupiter’s radiation belts. We summarize how these Juno measurements address issues of auroral processes, microphysical plasma physics, ionosphere-magnetosphere and satellite-magnetosphere coupling, sources and sinks of plasma, the radiation belts, and the dynamics of the outer magnetosphere. To reach Jupiter, the Juno spacecraft passed close to the Earth on October 9, 2013, gaining the necessary energy to get to Jupiter. The Earth flyby provided an opportunity to test Juno’s instrumentation as well as take scientific data in the terrestrial magnetosphere, in conjunction with ground-based and Earth-orbiting assets.

Aphids are known to live in symbiosis with speciÞc bacteria called endosymbionts that have positive or negative impacts on their hosts. In this study, six banana aphid (Pentalonia nigronervosa Coquerel) strains from various geographical origins (Gabon, Madagascar, and Burundi) were screened to determine their symbiotic content, using complementary genomic (16S rDNA sequencing and speciÞc polymerase chain reaction) and proteomic (two-dimensional difference gel electrophoresis coupled with protein identiÞcation by matrix assisted laser desorption-ionization time-of-ßight mass spectrometry) approaches. Despite the geographical heterogeneity, the combined methods allowed us to identify the same two symbionts in the six aphids strains tested: Buchnera aphidicola and Wolbachia. Although B. aphidicola is found in almost all aphid species, the systematic presence of Wolbachia in banana aphids is particularly interesting, as this bacterium usually has a low prevalence in aphid species. Phylogenetic analyses showed that the Wolbachia sp. strain found in P. nigronervosa was very similar to the strain present in aphids of the genus Cinara, known to have developed a strong and long-term symbiotic association with Wolbachia. The high level of asexual reproduction in P. nigronervosa could be linked to the presence of Wolbachia, but its prevalence also suggests that this symbiotic bacterium could play a more essential role in its aphid host.

In this talk, I provide a description of the various types of constructions used for expressing clausal (‘predicative’) possession in Late Egyptian. The corpus is comprehensively defined to include both literary and non-literary texts from the reign of Thutmose 3 (c. 1450 BC) down to abnormal hieratic texts (c. 600 BC), excluding most of the texts in Égyptien de tradition (i.e. purposely imitating various registers of EEg). The talk is structured in three sections that reflect both functional and structural features: (1) The adjectival predicate pattern or the marked expression of ownership; (2) The comitative strategy or the unmarked expression of possession; (3) Other types of predicative possession in Late Egyptian.

The present work is concerned by modal identification of time-varying systems. For this purpose, a method based on instantaneous frequency identification and synchronous demodulation is used to extract modal components from recorded signals. The proposed method of iterated sifting process is based on the Hilbert Vibration Decomposition (HVD) technique which is used to extract the instantaneous dominant vibrating component at each iteration. A source separation preprocessing step is introduced to treat multiple degree-of-freedom systems in an optimal way. Sources are used as reference signals to get a single instantaneous frequency of each mode for the demodulation on all the channels. The algorithm is presented and is applied to numerical simulation of a randomly excited time-varying structure for illustration purpose. The investigated structure is made up of a beam on which a non-negligible mass is traveling. The variable location of the mass results in changes in modal parameters. [less ▲]
