Intuitu fidelis servitii sui

In October 2012, Thérèse de Hemptinne retired after a successful academic career at the department of (medieval) History at Ghent University. Carrying on and strengthening the internationally recognized Ghent tradition of Auxiliary Sciences for the study of the Middle Ages, Thérèse de Hemptinne taught for many years the Bachelor’s and Master’s courses of Diplomatics and Palaeography. Following her research interests, which from the 1990s onward gradually expanded to focus on the position and role of women in a medieval man’s world, Thérèse de Hemptinne also integrated gender as a methodological tool of analysis into the Master’s courses ‘Historical Criticism’ and the ‘Gender Research Seminar’, and acted as a supervisor of many Master’s theses produced in the field of women and gender studies. The critical edition of the charters of the counts of Flanders Thierry and Philip of Alsace (1128-1191) can be considered one of the most important scholarly achievements of Thérèse de Hemptinne. Yet, her academic bibliography also testifies to her many other interests in medieval studies, among which political and institutional, social and cultural history of the Middle Ages, and particularly to her original gender-based approach to the discourse of medieval sources related to these areas. This volume is offered to Thérèse de Hemptinne by two of her students as a token of respect and gratitude for her services rendered and for her lifetime commitment to the department of (medieval) History as a teacher, as a senior researcher and scholar, as a mentor, as a colleague and as a friend. It contains the republication of a selection of Thérèse de Hemptinne’s most important and acclaimed articles and book chapters published during her academic career at Ghent University. The twenty one selected essays of Thérèse de Hemptinne are gathered around three themes: ‘Charters and Chanceries’, ‘Gender and Politics’, and ‘Women and Literacy’. Each chapter is introduced by an expert of international prominence

A non-additive repulsive contribution in an equation of state: The development for homonuclear square well chains equation of state validated against Monte Carlo simulation

International audienceThis work consists of the adaptation of a non-additive hard sphere theory inspired by Malakhov and Volkov, Polym. Sci. Ser. A. 2007;49(6):745-756 to a square-well chain. Using the thermodynamic perturbation theory, an additional term is proposed that describes the effect of perturbing the chain of square well spheres by a non-additive parameter. In order to validate this development, NPT Monte Carlo simulations of thermodynamic and structural properties of the non-additive square well (NASW) for a pure chain and a binary mixture of chains are performed. Good agreements are observed between the compressibility factor originating from the theory and those from molecular simulations

Kelimpahan Populasi, Preferensi Dan Karakter Kebugaran Menochilus Sexmaculatus (Coleoptera: Coccinellidae) Predator Kutudaun Pada Pertanaman Cabai

This predator is efective to control population of aphids, so the aim of research was to study the field population abundance, predator preference to this prey, and fitness character of M. sexmaculatus as predator. The population fluctuation was observed at conventional and organic farming. The preference test was conducted by choice and no choice test for some types of prey. Fitness test was performed by studying its prey, the number of eggs produced and number of eggs hatched. The results showed that M. sexmaculatus population abundance was fluctuated, the abundance higher in Chili cultivated conventionaly than cultivated in organic farming. But in conventional farming decreased with increasing age of Chili. Preference test showed that almost all species of aphids preferred by M. sexmaculatus. Some prey species found were aphids, thrips and Neotoxoptera. Predator fitness levels showed by the longevity of females ranged 9-10 days. Oviposition period was on average five days, while the post-oviposition was two days. The number of eggs produced ranged 100-200 eggs with an average of 135.3 eggs

Beta Oscillation-Targeted Neurofeedback Training Based on Subthalamic LFPs in Parkinsonian Patients

Increased oscillatory activities in the beta frequency band (13-30 Hz) in the subthalamic nucleus (STN), and in particular prolonged episodes of increased synchrony in this frequency band, have been associated with motor symptoms such as bradykinesia and rigidity in Parkinson's disease (PD). Numerous studies have investigated sensorimotor cortical beta oscillations either as a control signal for Brain Computer Interfaces (BCI) or as target signal for neurofeedback training (NFB). However, it still remains unknown whether patients with PD can gain control of the pathological oscillations recorded from a subcortical site - the STN - with neurofeedback training. We tried to address this question in the current study. Specifically, we designed a simple basketball game, in which the position of a basketball changes based on the occurrence of events of temporally increased beta power quantified in real-time. Participants practised in the game to control the position of the basketball, which requires modulation of the beta oscillations recorded from STN local field potentials (LFPs). Our results suggest that it is possible to use neurofeedback training for PD patients to downregulate pathological beta oscillations in STN LFPs, and that this can lead to a reduction of beta oscillations in the cortical-STN motor network

The Bougainvillea mealybug Phenacoccus peruvianus, a rapid invader from South America to Europe

Τα κοκκοειδή έντομα εμφανίζονται συχνά ως εισβολείς σε νέες περιοχές. Το είδος Phenacoccus peruvianus Granara de Willink, 2007, γνωστό και ως ψευδόκοκκος της βουκαμβίλιας παρατηρήθηκε για πρώτη φορά στην Ευρώπη το 1999 στην Ισπανία (Αλμερία) και αργότερα το 2002 στην Ιταλία (Σικελία). Αρχικά το είδος είχε αναγνωριστεί ως Phenacoccus sp. Κατα- γραφές του είδους έγιναν συχνότερες και σε άλλες περιοχές της Ισπανίας (συμπεριλαμβανομέ- νων και των Βελεαρίδων νήσων), στη Μ. Βρετανία, τη Γαλλία (συμπεριλαμβανομένης και της Κορσικής), το Μονακό και την Πορτογαλία. Τα φυτά ξενιστές ήταν στις περισσότερες περι- πτώσεις του γένους Bougainvillea.Scale insects are frequent invaders of new territories. The Bougainvillea mealybug, Phenacoccus peruvianus Granara de Willink, 2007, was recorded in Europe for the first time in 1999 in Spain (Almeria) and later in 2002 in Italy (Sicily). Initially, this unknown species was identified provisionally as Phenacoccus sp. Records of this species became frequent later when it was found in other localities in Spain (including the Balearic Islands), Great Britain, France (including Corsica), Monaco, and Portugal. The host plants of this mealybug were in most cases species of Bougainvillea
