    La descolectivización de la agricultura en Armenia o las dificultades de la transición post soviética

    The agriculture of Armenia, a former Soviet Republic, has been affected by the disaster brought about by the falling of the URSS. The strong descolletivization of the agricultural sector has marked the beginning of a period of post-collective transition. Over ten years after the independence, both the economy and particularly the agricultural sector still suffer serious dysfunction, worsened by the historical heritage of genocide, the Karabagh conflict and the blockade of the border. Even so, certain local dynamics confirm the strong agricultural potential of this small Christian state at the south 01 the Caucasus

    Pseudoclypeina? crnogorica Radoičić, 1972: Stratigraphic revision and taxonomic note on a little known dasycladalean alga from Montenegro

    Get PDF
    Pseudoclypeina? crnogorica was first described in 1972 from the Lower, Cretaceous limestone of the Njegoš Mt. area, Montenegro, Dinaric Carbonate Platform. It differs from other species of the genus Pseudoclypeina by its calcification pattern, the shape and relative length of the first and second order laterals, and by the presence in the type-material (a thin section containing the holotype) of sections standing for the sterile portion of the thallus. This is why in this paper, the generic name is left in open nomenclature. On this occasion the species, whose presence is also reported from southern Iran, is re-described and better illustrated, based on material originating from other outcrops in Montenegro. The stratigraphic position is reviewed as well. Pseudoclypeina? crnogorica occurs in shallow water inner platform facies of early Neocomian age, along with Selliporella neocomiensis

    Etude du comportement dynamique de broche d'un centre d'usinage dans son espace de travail : application en fraisage

    Une méthodologie est proposée dans cet article dans le but de faciliter l’évaluation de la stabilité d’une opération de fraisage, pour une broche, un outil et une position connue de la broche dans son espace de travail. L’approche se base sur une procédure d’indentification du comportement dynamique de la broche qui se suit par un couplage des FRF du système (broche et attachement) avec le tronçon avant de l’outil d’usinage pour prédire la FRF en sa pointe. Celle-ci permet à l’aide d’une résolution analytique de l’équation caractéristique de la dynamique de fraisage dans le domaine fréquentiel de prédire la limite de stabilité critique. Dans le but d’étudier la variabilité du comportement dynamique du système usinant dans son espace de travail, la même démarche est appliquée dans différentes positions. Les profondeurs de passe critiques obtenu pas simulations sont comparées à celles qui sont obtenues par fraisage.The aim of this work is to provide a methodology helping on the evaluation of the milling process stability for a given spindle, tool and work space position of the spindle. The proposed approach is based on the spindle dynamic behavior identification. Then, a FRF coupling is made between the identified system and the tool model in order to obtain the FRF at the tool tip. Therefore, the critical depth of cut can analytically be calculated from the characteristic equation of the dynamic milling process in the frequency domain. In order to study the variability of the dynamic behavior of the spindle in the work space, the same approach is then, applied at different positions and compared against experimental milling.Financement de thèse CIFR

    Quantum well infrared photodetectors hardiness to the non ideality of the energy band profile

    We report results on the effect of a non-sharp and disordered potential in Quantum Well Infrared Photodetectors (QWIP). Scanning electronic transmission microscopy is used to measure the alloy profile of the structure which is shown to present a gradient of composition along the growth axis. Those measurements are used as inputs to quantify the effect on the detector performance (peak wavelength, spectral broadening and dark current). The influence of the random positioning of the doping is also studied. Finally we demonstrate that QWIP properties are quite robust with regard to the non ideality of the energy band profile

    An empirical analysis of the nine Internet Gaming Disorder criteria

    Internet Gaming Disorder (IGD) has received increased scientific attention since May 2013, and its assessment can be conducted using the nine criteria suggested by American Psychiatric Association (APA). This study examined the role of each IGD criterion using a conditional inference tree model. Methods: A total of 3,377 gamers (82.7% male, mean age 20 years, SD = 4.3 years) were recruited to the present study. In addition to collecting sociodemographic information, participants filled out the Internet Gaming Disorder Scale–Short-Form (IGDS9-SF) based on the DSM-5 criteria. Results: The conditional inference tree model revealed that endorsement of ‘withdrawal’ (criterion 2) and ‘loss of control’ (criterion 4) increased the likelihood of IGD by 77.77% (95%CI: 62.09–93.45) while endorsing ‘withdrawal’, ‘loss of control’ and ‘negative consequences’ (criterion 9) increased the likelihood of IGD by 26.66% (95%CI: 4.28–49.04). Finally, not endorsing ‘withdrawal’ but endorsing ‘preoccupation’ (criterion 1) increased the probability of IGD by 7.14% (95%CI: 1.63–12.65). Conclusions: Overall, these results suggest that not all IGD criteria carry the same diagnostic weight as each criterion can play a different role in the development of IGD. It is envisaged that these findings will help improve the assessment of IGD in the future
