description: If light--flavor squarks and gluinos are indeed heavy and chargino pair production is plagued with overwhelming backgrounds, pair production and associated production of stops and charginos will become the key signatures in the upcoming LHC runs. We present fully automated next-to-leading order predictions for heavy flavor squark production at the LHC, including stop-chargino associated production, based on MadGolem. We compute the total and differential NLO rates for a variety of MSSM scenarios with a light third generation. We focus on theoretical uncertainties on differential rates, including a comparison to multi-jet merging and the impact of bottom parton densities for stop-chargino associated production. We find that for the associated production channel the rates can reach tens of femtobarns, but the scale dependence does not provide a conservative estimate of the theoretical uncertainties.

description: Background: In the treatment of tall stature, the reduction of excessive predicted final height can either be achieved by hormonal treatment or surgically by temporary (tED) or permanent (pED) epiphysiodesis. The present study evaluates the preliminary results of two novel devices for tED and pED around the knee to reduce the predicted final height. Materials and methods: A retrospective analysis was performed to evaluate the clinical and radiographic outcome after bilateral epiphysiodesis for the treatment of tall stature. A cohort of 34 patients (16 girls, 18 boys) who underwent either tED or pED between 2015 and 2020 were eligible for analysis based on the electronic patient records and picture archiving and communication system of our orthopaedic teaching hospital. tED was conducted in 11 patients (32%) through bilateral implantation of four RigidTacks™ (Merete, Berlin, Germany) around the knee. Twenty-three patients (68%) received pED, performed with an EpiStop™ trephine (Eberle, Wurmberg, Germany). The mean overall follow-up time was 2.9 years. Results: The mean age at surgery was 12.3 years in girls and 13.2 years in boys. Patients had a mean body height of 175.2 cm in girls and 184.7 cm in boys at surgery. The mean predicted final height was 191.4 cm in girls and 210.4 cm in boys. At the last follow-up, 26 patients (76.5%) had achieved skeletal maturity. The mean height of skeletally mature patients was 187.2 cm in girls and 198.5 cm in boys. A mean reduction of the predicted final height of 5.9 cm in girls and 8.7 cm in boys was achieved, corresponding to a reduction in remaining growth of 46% in girls and 38% in boys. Secondary frontal plane deformities of the knee were detected in 5/11 patients (45.5%) in the tED group and 1/23 treatments (4.3%) in the pED group. Conclusions: tED and pED have both proven to be efficient at achieving growth inhibition to reduce excessive predicted height. However, tED has been associated with an increased risk of secondary angular deformities of the knee. Furthermore, the risk of implant-related complications and the necessity of a subsequent surgical intervention for implant removal have led our study group to abandon tED when treating tall stature. Long-term results of both procedures are pending. Level of evidence: 4.

description: Ever since Georg Simmel (1895) introduced the notion into sociological accounts of modernity, scholars have tried to empirically test the claim of an increasing “speed of life” in modern society. The acceleration of speed or pace of life has been characterized as an “intensification” of our experience of time, a “time squeeze,” and “hurriedness” in leisure time. However, to date, no comprehensive instrument, scale, or indicator has been developed that is grounded in solid theory and serves to empirically measure and compare the pace of life in a straightforward manner. The purpose of this research is to develop and validate a scale-based measure that reveals whether individuals pursue a fast or slow pace of life in a leisure-time context. The result is the fifteen-item General Acceleration Scale (GAS), which conceptually rests on the comprehensive theory of social acceleration by Hartmut Rosa (2013). The scale systematically tests the pace of life along four temporal strategies of speedup: performing activities faster, doing multitasking, replacing time-consuming by time-saving activities, and filling breaks or waiting times with productive activities. If these temporal strategies form a consistent pattern, they consequently lead to an increase in the rate, speed, or relative density of experiences and activities per unit of time and thus to an increase in the pace of life. Validation of the GAS was completed by a large sample (N = 1161) as part of a self-report online survey in Germany in 2019. We examined the convergent and discriminant validity as well as internal consistency reliability of the scale and conducted a confirmatory factor analysis via maximum likelihood estimation. Control variables and discriminant measures were included to access construct validity. Overall, we can validate the GAS as a reliable measure of time use that can be used as a straightforward pace of life indicator.

description: The problem of a mode I crack having multiple contacts between the crack faces is considered. In the case of small contact islands of arbitrary shapes, which are arbitrarily located inside the crack, the first-order asymptotic model for the crack opening displacement is constructed using the method of matched asymptotic expansions. The case of a penny-shaped crack has been studied in detail. A scaling hypothesis for the compliance reduction factor is formulated.

description: Mixing of spin singlet and spin triplet superconducting pairing state is expected in noncentrosymmetric superconductors (NCS) due to the inherent presence of Rashba-type antisymmetric spin-orbit coupling. Unlike low symmetry (tetragonal or monoclinic) NCS, parity is isotropicaly broken in space for cubic NCS and can additionally lead to the coexistence of magnetic and superconducting state under certain conditions. Motivated with such enriched possibility of unconventional superconducting phases in cubic NCS we are reporting successful formation of single crystalline cubic noncentrosymmetric PdBiSe with lattice parameter a = 6.4316 Å and space group P2_1 3 (space group no. 198) which undergoes to superconducting transition state below 1.8 K as measured by electrical transport and AC susceptibility measurements. Significant strength of Rashba-type antisymmetric spin-orbit coupling can be expected for PdBiSe due to the presence of high Z (atomic number) elements consequently making it potential candidate for unconventional superconductivity.

description: The PhD thesis in Mathematics titled "Old and New Problems in continuum structural masterials " is divided into two parts. In Part I ( Chapter I and II relative to the " Old Problems" ) is studied in particular the classic behavior of materials from the mechanical point of view. In Chapter I were determined tensors of stress and strain in a solid having the shape of a hollow cylindrical , that is not simply connected , when it does act on it a displacement field able to induce all six elementary distortions of Volterra in the case where the material constituting the solid is homogeneous , linearly elastic and transversely isotropic . Unlike Volterra considers an isotropic body, characterized by two elastic constants : (E and G) , presents in the constitutive relations of the material become five (A, C, F, L and N). The result obtained is that the functions of displacement [u1 (x,y,z), u2 (x,y,z), u3 (x,y,z) ] . meet the indefinite equations of elastic written using the five elastic constants , but as Volterra , they do not cancel the load over the entire border of the hollow cylinder . In other words, do not give rise to a real distortion in that the action of the shift functions do not carry the cylinder from a natural configuration to a spontaneous through an isothermal transformation in which the load boundary is null but only self- balanced...

description: Ce mémoire professionnel se compose d’une méta-analyse agrémentée d’interventions de professionnels du monde de l’enseignement, de la pédagogie, du développement de l’enfant, de la santé et du sport. Elle a permis de mettre en relief les bénéfices et les obstacles liés à l’introduction et/ou au maintien d’enseignants spécialistes en éducation physique et sportive dans les cycles primaire et de transition de l’école vaudoise actuelle. Les études scientifiques et empiriques, ainsi que la littérature, démontrent maints bénéfices importants liés à l’activité physique de qualité et en suffisance dans le milieu scolaire. Si l’implication d’enseignants spécialistes EPS permettrait d’améliorer la qualité de l’enseignement dispensé et donc le développement de l’enfant relativement aux aspects moteurs, cognitifs, culturels, hygiéniques et sécuritaires, les aspects psychologiques et sociaux se voient quant à eux nuancés. La grande majorité des intervenants s’accordent à dire que l’introduction de maîtres de sport dès l’âge de 6 ans serait pédagogiquement et didactiquement d’un apport considérable et permettrait d’une part, la constitution de bases psychomotrices et sociales saines, d’autres part de donner du sens à l’activité physique. En effet, un bagage moteur, cognitif et psychosocial acquis harmonieusement durant les années de « l’âge d’or » reste en mémoire durant toute sa vie d’adulte. Toutefois des obstacles d’ordres politiques, financiers, structuraux, de formation et émotionnels sont à considérer et rendent difficile la introduction et/ou le maintien d’enseignants EPS au CYP et au CYT. C’est pourquoi nous avons envisagé plusieurs solutions de la plus drastique aux plus flexibles.

description: A detailed study of a model for strongly-interacting fermions with exclusion rules and lattice $\mathcal N=2$ supersymmetry is presented. A submanifold in the space of parameters of the model where it is Bethe-ansatz solvable is identified. The relation between this manifold and the existence of additional, so-called dynamic, supersymmetries is discussed. The ground states are analysed with the help of cohomology techniques, and their exact finite-size Bethe roots are found. Moreover, through analytical and numerical studies it is argued that the model provides a lattice version of the $\mathcal N=1$ super-sine-Gordon model at a particular coupling where an additional $\mathcal N=(2,2)$ supersymmetry is present. The dynamic supersymmetry is shown to allow an exact determination of the gap scaling function of the model.

description: Nanosatellite technology opens up new possibilities for Earth observation. We expect that in the next decade large satellite constellations will arise with hundred, up to thousand satellites in low Earth orbit. While most constellations will be dedicated to internet of things and global communication, a larger number of satellites will be also equipped with rather low-cost sensors, such as GNSS receivers, suited for monitoring of the Earth’s atmosphere. However, future evolution of atmospheric science leans not only on densified observing systems but also on new, more complex analysis methods. In this respect, tomographic principles provide a unique opportunity for sensor fusion and therefore, contribute to a better understanding of the specific sensor characteristics and to exploit their full potential for sensing the three-dimensional atmospheric state. One difficulty in performing the conversion of integral measurements into three-dimensional images is that the signal ray path is not a straight line but rather dependent on the object properties along the signal path. Another challenge is related to the limited number of radio sources and detectors with respect to the size of the object of interest. Therefore, the inverse problem is either solved linearly or iterative non-linear. In this chapter, the individual solving techniques for the tomographic problem are presented, including strategies for removing deficiencies of the ill-posed problem by using truncated singular value decomposition and L-curve technique. Applied to dense nanosatellite formations, a new quality in the reconstruction of the 3D water vapor distribution is obtained, which has the potential for leading to further advances in atmospheric science.

description: Ce travail présente une sélection de moyens d'enseignement pour la biologie au secondaire II disponibles sur Internet, obtenue par le biais d'une recherche dans Google. Il existe quantité de ressources qui peuvent être utiles à un enseignant pour compléter son cours ou le rendre plus attractif. Le plan d'études vaudois a été pris comme fil conducteur pour effectuer cette recherche. Les résultats de celle-ci offrent une sélection qui n'est pas exhaustive dans la mesure où elle a été établie à partir d'objectifs de recherche définis (en suivant ce plan d'études). Il a été délibérément choisi de cibler le public appartenant aux classes de maturité avec la biologie comme discipline fondamentale et option spécifique. En principe, les contenus de l'option spécifique couvrent l'ensemble du programme de biologie au secondaire II. Cette sélection de moyens d'enseignement est tout à fait utilisable dans toute autre voie du secondaire II (culture générale, orientation santé…) où la biologie est enseignée et également dans le secondaire I pour la biologie intégrée dans les sciences naturelles, avec adaptation en fonction du niveau des élèves. La première étape a consisté à mettre en relation le plan d'études vaudois et la taxonomie de Bloom révisée par Anderson et Kathwohl. Ainsi, les savoir-faire et savoirs ont été mis en relation avec les objectifs d'apprentissage et habiletés cognitives de cette taxonomie. Cela a permis de faire un inventaire des objectifs d'apprentissage et habiletés cognitives que l'on peut trouver dans l'enseignement de la biologie en analysant le plan d'études. La deuxième étape a consisté à établir une liste des contenus propres à la biologie et définis par le plan d'études vaudois. Cette liste a servi à définir les objectifs de recherche sur Internet. La recherche proprement dite a consisté à prendre les contenus et les travaux pratiques définis par le plan d'études l'un après l'autre, et à faire une recherche dans le moteur de recherche Google. Ce travail montre que l'on trouve des ressources qui permettent de couvrir l'ensemble du plan d'études vaudois. Néanmoins, on trouve principalement des ressources qui paraissent utiles pour développer les deux premiers objectifs d'apprentissage de la taxonomie de Bloom, à savoir Restituer et Comprendre. Il appartiendra toujours à l'enseignant de vérifier, ainsi que de modifier ou adapter ces ressources au besoin, comme d'ailleurs avec des ressources provenant de supports classiques, pour travailler sur d'autres objectifs d'apprentissage avec ses élèves.

description: Cette étude a pour but d'établir un bilan des connaissances des gymnasiens autour du thème des fractions. Nous avons eu à disposition un échantillon d'environ 150 élèves répartis en plusieurs niveaux et classes. Nous nous sommes inspirés de Rouche (1998) et des questions du LMT 2008 pour élaborer un questionnaire qui comporte deux parties : une axée sur les représentations composée de quatre questions et une deuxième plus calculatoire composée elle aussi de quatre questions. Ce questionnaire a été créé dans le but de mieux cerner les connaissances des élèves sur le sujet, ainsi que d'analyser la corrélation entre les représentations et les capacités calculatoires. Nous nous sommes aussi interrogés sur une éventuelle progression des connaissances en matière de fraction selon le niveau mathématique des élèves et leur position dans le cursus gymnasial. Nos résultats montrent que même dans un sujet fondamental et de base comme celui des fractions, nombreux sont les gymnasiens qui montrent des difficultés. Il existe une progression des connaissances des élèves sur les fractions lors de leur cursus gymnasial. Cette progression est plus intense au niveau du calcul mais non négligeable au niveau des représentations. Une corrélation positive entre représentations des fractions et capacité calculatoire avec les fractions a été remarquée, même si l'amplitude de cette corrélation n'est pas aussi grande qu'espérée. On peut toutefois remarquer que les élèves ayant de « bonnes » représentations montrent moins de problèmes de calcul avec les fractions. Etant donné les difficultés remarquées et la possibilité de progresser des élèves, travailler ce sujet même au niveau du secondaire II aurait un sens et probablement un effet sur nos élèves.

description: We report the fabrication of low-leakage rectifying Pt and Au Schottky diodes and Au-gated metal-semiconductor field effect transistors (MESFETs) on n-type SrTiO3 thin films grown by hybrid molecular beam epitaxy. In agreement with previous studies, we find that compared to Pt, Au provides a higher Schottky barrier height with SrTiO3. As a result of the large dielectric constant of SrTiO3 and the large Schottky barrier height of Au, the Au-gated MESFETs are able to modulate ~1.6 x 1014 cm-2 electron density, the highest modulation yet achieved using metal gates in any material system. These MESFETs modulate current densities up to ~68 mA/mm, ~20x times larger than the best demonstrated SrTiO3 MESFETs. We also discuss the roles of the interfacial layer, and the field-dependent dielectric constant of SrTiO3 in increasing the pinch off voltage of the MESFET.

Au cours des dernières décennies, les chercheurs ont en effet porté une attention grandissante à l’élève en tant que lecteur concret. Ces pratiques, déjà en vigueur au primaire et au secondaire I, intéressent de plus en plus les enseignants du degré postobligatoire. Toutefois, l’aspect subjectif inhérent à une telle démarche peut compromettre sa démocratisation à large échelle ; l’héritage de la poétique structuraliste étant encore très présent dans les esprits. Au fil de ces quelques pages, nous tenterons de traiter des aspects théoriques et pratiques d’une approche de l’analyse de texte centrée sur le sujet lecteur. Dans une brève introduction, nous donnerons un aperçu de l’état de la recherche en didactique de l’enseignement de la littérature. Le premier chapitre, consacré à la pratique de l’analyse de texte en classe, nous amènera à discuter des conventions en la matière et des limites imposées par la poétique structuraliste. Puis nous donnerons, dans le deuxième chapitre, des exemples d’activités sur les textes inspirées de la théorie de la réception. Finalement, le troisième chapitre sera consacré à l’étude de travaux d’élèves ; ce sera, par conséquent, l’occasion de démontrer la validité de notre hypothèse de départ, à savoir que la mise en place de dispositifs centrés sur le sujet lecteur est à la fois pertinente et bénéfique au sein de l’enseignement postobligatoire.

description: Quelle est la trajectoire professionnelle de nouveaux enseignants au cours de leurs premières années de travail ? Trouvent-ils facilement un emploi ? Cet emploi est-il stable ? L’obtention d’un diplôme d’enseignant est un passeport vers un emploi plus aisé que d’autres études de hautes écoles. Cet emploi peut être un emploi instable, sans garanties pour l’avenir. Nous ne parlons pas ici du statut de fonctionnaire, mais de l’attente, justifiée, qu’à travail bien effectué l’emploi sera gardé, sauf cas de récession économique. Dans l’enseignement primaire, presque la moitié des postes ne remplissent pas cette attente. La majorité d’entre eux deviendront des postes stables, mais en début d’année il n’y a aucune garantie. L’enseignant remplaçant n’est pas maître de son avenir professionnel. Tout comme il n’exprime presque jamais avoir pu choisir son établissement. Le sentiment général qui se dégage des réponses au questionnaire est qu’on arrive par hasard dans un établissement ou tout du moins le nouvel enseignant ne sait pas pourquoi on l’a pris, lui ou elle, plutôt qu’un ou une autre. Si le nouvel employé dans une entreprise privée ne peut se targuer de savoir pourquoi il a obtenu un poste. Il sait, usuellement, que son contrat va continuer aussi longtemps qu’il donne satisfaction, sauf apocalypse économique. Ce qui n’est pas le cas du jeune enseignant. On peut séparer l’insertion professionnelle des enseignants sur deux axes : Les cantons ou régions de formation et le niveau d’enseignement. Ce sont les cantons ou régions, dans le cas de BEJUNE, qui sont les plus grands facteurs de variations dans l’obtention d’un poste à la rentrée scolaire. Par contre, le type de poste, remplacement ou fixe, est lui déterminé principalement par le niveau d’enseignement. Les enseignants d’enfantine – primaire se verront proposer, pour presque la moitié d’entres eux, un remplacement et les enseignants secondaire, à plus de huitante-cinq pour cent, un poste fixe. De plus, les remplacements dans le secondaire sont, à plus de 90 %, des remplacements d’une année. Un enseignant d’enfantine – primaire a donc plus de difficultés à trouver un poste stable, dès le début, qu’un enseignant de secondaire. Ce qui est à l’opposé des statistiques usuelles sur l’insertion professionnelle des HES et des universités.

Cover the blood: a theoretical and creative-practice examination of intra-activity and documentary filmmaking
Creators: name: Gottlieb, Jacob
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis proposes a posthuman philosophical framework for investigating the relationship between autoethnographic filmmakers and the films they make. It begins with a discussion of intra-activity (Barad, 2003) and its applications to filmmaking processes (Benjamin, 1935, Anders, 1956). It then considers first-person, essay, autobiographic, and auto-ethnographic filmmaking practices through the lens of this intra-active framework, asking how such filmmakers are engaged in renegotiating, embodying, and enacting boundaries of agency. The documentary-films Heart of a Dog (Anderson, 2015), I want to make a film about women (Pearlman, 2019), and The Gleaners and I (Varda, 2000) are analysed as examples of how the intra-active framework might interpret particular films and their formal construction. This research outlines and resists the habit of representationalism in film theory and posits an understanding of filmmaker and film as authoring one another in the filmmaking process. This research also includes a creative-practice film, Cover the Blood (2021), which is an investigation and enaction of the ideas discussed within the written thesis.

description: Photolithography is a process in the production of integrated circuits in which a mask is used to create an exposed pattern with a desired geometric shape. In the inverse problem of photolithography, a desired pattern is given and the mask that produces an exposed pattern which is close to the desired one is sought. We propose a variational approach formulation of this shape design problem and introduce a regularization strategy. The main novelty in this work is the regularization term that makes the thresholding operation involved in photolithography stable. The potential of the method is demonstrated in numerical experiments.

description: Biofouling on marine renewable energy devices presents engineering challenges for this developing sector, and has implications for the spread of marine non-native species (NNS) in coastal waters. This is particularly true at sites with abundant energy resource, little existing infrastructure, and few established NNS. Device coatings, such as antifouling paints, could reduce the risk of NNS spread. Settlement on coatings of various types and colours, representing those likely to be used on renewable energy devices, was assessed in the Orkney Islands, northern Scotland. Assemblage composition, but not overall biofouling cover, varied initially among different coloured surfaces, although differences decreased over time. Different coating types (an anticorrosive paint, a biocidal paint and a fouling-release coating) differed in biofouling abundance and composition for the full duration of the experiment. NNS were mostly, but not completely, absent from antifouling surfaces. These results can help informing antifouling strategies for the marine renewable energy industry.

description: For a simple graph $G=(V,E)$ and for a pair of vertices $u,v \in V$, we say that a vertex $w \in V$ resolves $u$ and $v$ if the shortest path from $w$ to $u$ is of a different length than the shortest path from $w$ to $v$. A set of vertices ${R \subseteq V}$ is a resolving set if for every pair of vertices $u$ and $v$ in $G$, there exists a vertex $w \in R$ that resolves $u$ and $v$. The minimum weight resolving set problem is to find a resolving set $M$ for a weighted graph $G$ such that$\sum_{v \in M} w(v)$ is minimum, where $w(v)$ is the weight of vertex $v$. In this paper, we explore the possible solutions of this problem for grid graphs $P_n \square P_m$ where $3\leq n \leq m$. We give a complete characterisation of solutions whose cardinalities are 2 or 3, and show that the maximum cardinality of a solution is $2n-2$. We also provide a characterisation of a class of minimals whose cardinalities range from $4$ to $2n-2$.

description: Dans un système éducatif où l’accent est mis sur l’approche herméneutique des textes, où les œuvres étudiées sont déterminées par les enseignants dans le cadre d’un programme officiel, où la lecture littéraire peut être associée par les élèves à des images de contrainte et d’ennui, comment faire naître chez ces derniers le plaisir de lire à partir de la contrainte de lectures imposées ? Comment instaurer un va-et-vient entre « participation psychoaffective » et « distanciation critique », entre subjectivité et objectivité, entre lecture émotive et lecture analytique ? S’il existe de nombreuses situations susceptibles d’interpeller les élèves et de provoquer chez eux questionnement et implication, le propos de ce travail est de s’interroger sur l’utilité de sortir de la classe pour mieux appréhender une œuvre. Envisager la lecture sous l’angle de la promenade, c’est insinuer que l’acte de lire est non seulement un voyage – un déplacement d’un lieu à un autre, d’un espace réel à un espace imaginé – mais c’est également y introduire les notions de plaisir et de détente, qui font parfois défaut aux programmes en vigueur. Comment, à travers la pratique de la promenade, rendre un texte plus vivant dans la représentation des élèves ? Quelles sont les différentes approches pouvant être mises en œuvre ? Quels sont les objectifs et les apports d’une telle démarche ? Quelles en sont les limites ? Afin de répondre à ces questions, ce travail s’attarde, dans un premier temps, sur le contenu et les objectifs de l’enseignement du français au niveau post- obligatoire, et plus particulièrement sur les divers éléments à prendre en compte lors de l’apprentissage de la lecture littéraire. Une fois ces questions traitées, il s’agit de définir en quoi peut consister une promenade littéraire, mais aussi quelle peut être sa place au sein de l’enseignement de la littérature. Enfin, le lecteur découvrira trois propositions d’approche régionale de la promenade littéraire.

description: We consider solutions of massive IIA supergravity corresponding to the half-BPS intersection of D8/D4-branes with fundamental strings. The $1+1$-dimensional intersection preserves the symmetry $D(2,1;γ;1) \times SO(4)$. We give a reduction and partial integration of the BPS equations for this symmetry group. We then specialize to the cases of enhanced supersymmetry corresponding to $γ= -1/2,-2$ or $γ= 1$. In the first case, we show that the only solution with enhanced symmetry is given by the $AdS_6$ geometry describing the near horizon geometry of D8/D4-branes in the presence of an O8-plane. In the second case, we identify novel solutions corresponding to fundamental strings ending on D8-branes and a second set of novel solutions corresponding to fundamental strings ending on an O8-plane. In both cases, the fundamental string geometry contains an asymptotically flat region where the string coupling goes to zero. We also show that there are no solutions corresponding to $1+0$-dimensional CFTs, which one may have hoped to construct by suspending fundamental strings between D8-branes.

description: Extracts of Centella asiatica leaves (LEs), and in-vitro leaf-calli (CEs), were investigated for antibacterial, antibiofilm, and anti-quorum sensing activities. Ethyl acetate extracts from leaves (EALE), leaf-calli (EACE), methanolic extracts from leaves (MELE), and leaf-calli (MECE) showed antibacterial activity; the minimum inhibitory concentrations (MICs) of LEs and CEs ranged from 0.312–2.50 mg ml−1 and 0.625 − 2.50 mg ml−1, respectively. The MICs of EALE and EACE were 2.50 mg ml−1, each, for C. violaceum 12742, and P. aeruginosa PAO1. At sub-MIC levels, EALE and EACE showed anti-quorum sensing (anti-QS) activity, demonstrated by concentration dependent pigment inhibition of C. violaceum 12742. Similarly, EALE and EACE inhibited QS-controlled virulence factors in P. aeruginosa PAO1 (biofilm, pyocyanin, and pyoverdin); again, the inhibition was concentration-dependent. The best effect was at immediate sub-MIC concentration i.e. 1250 µg ml−1. GC-MS analyses revealed the presence of compound 9,12-Octadecadienoic acid, and in silico docking study suggested interactions with QS-receptors CviR', LasI, and LasR proteins for anti-QS activity.

description: Algal biofilms, ubiquitous in aquatic systems, reduce the performance of engineered systems and alter ecosystem processes. Biofilm morphology is dynamic throughout community development, with patchiness occurring due to periodic sloughing, but little is known about how community level physical structure affects hydrodynamics. This study uses high resolution particle image velocimetry (PIV) to examine spatially explicit turbulence over sparse, uniform and patchy biofilm at turbulent Reynolds numbers. All biofilms increase the near-bed turbulence production, Reynolds shear stress, and rotational flow compared to a smooth wall, and non-uniform biofilms have the greatest increase in these parameters, compared with a uniform or sparse biofilm. However, a higher drag coefficient over uniform biofilm compared with non-uniform biofilm indicates that percent coverage (the amount of area covered by the biofilm) is a useful predictor of a biofilm’s relative effect on the total drag along surfaces, and in particular the effect on ship performance.

description: Σκοπός: Η συγκριτική αξιολόγηση δύο συστημάτων μηχανοκίνητων μικροεργαλείων NiTi όσον αφορά την πρόκληση μετατόπισης του ακρορριζικού τρήματος και τη μεταβολή του μήκους εργασίας. Υλικά και Μέθοδος: 40 εγγύς ριζικοί σωλήνες γομφίων της κάτω γνάθου κατανεμήθηκαν τυχαία σε 2 πειραματικές ομάδες ανάλογα με το μηχανοκίνητο σύστημα προπαρασκευής: Edge Taper Platinum και Edge One Fire. Τα δοκίμια ακτινογραφήθηκαν με μία ρίνη K #15, πριν και μετά την προπαρασκευή κάτω από τις ίδιες συνθήκες. Στη συνέχεια, υπολογίστηκε η διαφορά του μήκους εργασίας και η μετατόπιση του ακρορριζικού τρήματος με τη χρήση του λογισμικού EndoPrep App και της ψηφιακής αφαιρετικής ακτινογραφίας. Αποτελέσματα: Το σύστημα Edge Taper Platinum είχε μεγαλύτερη επίδραση στη μετατόπιση του ακρορριζικού τρήματος ενώ το σύστημα Edge One Fire είχε μεγαλύτερη επίδραση στη διαφορά του μήκους εργασίας. Σε καμία από τις 2 πειραματικές ομάδες δεν παρατηρήθηκε στατιστικά σημαντική συσχέτιση μεταξύ διαφορας μήκους εργασίας και μετατόπισης του ακρορριζικού τρήματος. Συμπεράσματα: Και τα δύο συστήματα μικροεργαλείων NiTi, Edge Taper Platinum και Edge One Fire προπαρασκεύασαν με ασφάλεια και αποτελεσματικότητα κεκαμμένους εγγύς ριζικούς σωλήνες κάτω γομφίων ex vivo.
description: (Aim: The comparative evaluation of two engine-driven NiTi file systems, apical foramen transportation and working length change. Materials and Methods: 40 mesiolingual canals of human extracted mandibular molars were selected and each specimen was randomly allocated to one of the two experimental groups, according to the system used for instrumentation: Edge Taper Platinum and Edge One Fire. Radiographs of the specimens where taken with a K#15 file at working length before and after instrumentation. The difference in working length and apical foramen transportation were calculated using a combination of the EndoPrep App software and digital subtraction radiography. Results: Edge Taper Platinum had greater effect on apical foramen transportation whereas Edge One Fire had greater effect on working length change. None of the two experimental groups had a statistically significant correlation between working length change and apical foramen transportation. Conclusion: Both NiTi file systems instrumented safely and efficiently mesiolingual root canals of lower molars ex vivo.

description: This research carried out under the guidance of Mrs. A. Pontrandolfo, Professor at the Salerno university and Mrs. Rouveret, Professor at the Paris X University. Our main goal is to rebuild the diachronic, dynamical, more articulated and less fragmented picture of types of occupation and transformation of the periurban area and of the northern and eastern chora of Poseidonia-Paestum, between the Sele river, in the north, and the actual town of Roccadaspide, in the east, in the period between the foundation of the Greek polis and the resulting Latin colony. The methodological assumptions at the basis of this study are: the "critical" revision of the known information in bibliography, filed documents, diaries of excavations and reports of the Superintendence officers integrated by study of the paleoenvironmental dynamics, and verifications, formalization and aggragation of data aiming to an historical interpretation. The core of this research is the philological analyses of the materials obtained in different ways: an essential anchorage point and a basis for the interpreting proposals relevant to the dynamics of the occupation of the periurban space and the area in the north and in the east of Poseidonia- Paestum. To the census of the unplublished and the filed information, to their geo-localization - when possible - to the analyses of the materials some further data were added. These data are provided by the methodical surfaces reconnissance which, since 2003, have been involving the territory of Poseidonia-Paestum. The archaeological research has shown that before the monumentalization, the city spaces are clearly defined and their outline is based on their functions and on their usages. The northerly and easterly territory is characterized by meaningful presences which play a fundamental role in relationship with the native elements since the beginning of the IV century BC and which adopt different values and connotations until the Romanization.
