description: We introduce an approach which allows a detailed structural and quantitative analysis of multipartite entanglement. The sets of states with different structures are convex and nested. Hence, they can be distinguished from each other using appropriate measurable witnesses. We derive equations for the construction of optimal witnesses and discuss general properties arising from our approach. As an example, we formulate witnesses for a 4-cluster state and perform a full quantitative analysis of the entanglement structure in the presence of noise and losses. The strength of the method in multimode continuous variable systems is also demonstrated by considering a dephased GHZ-type state.

description: Dans le cadre de l’éducation physique, l’enfant est souvent attiré par les grands engins qui lui donnent envie de bouger. Les agrès se prêtent bien pour faire vivre à l’enfant des situations inhabituelles qui lui permettent d’exercer l’équilibre, la grimpe, les rotations, les balancements, les sauts, etc. Ces expériences lui sont indispensables pour qu’il puisse bien développer sa motricité et pour lui permettre d’apprendre à évaluer les dangers et à gérer les risques. En outre, les activités aux agrès permettent de développer la coopération et l’entraide. De ce fait, les situations que l’enfant peut expérimenter aux agrès contribuent à son développement physique, social et mental. Cependant, les agrès représentent une discipline particulièrement technique qui requiert une certaine connaissance du matériel et des exercices afin qu’il soit possible d’organiser une activité se déroulant en sécurité. Pour cette raison, la discipline des agrès est parfois mise à l’écart lors des cours d’EPS scolaire. Le but de ce mémoire professionnel est d’étudier la place qu’accordent les maîtres généralistes aux agrès lors des leçons d’EPS. Pour cela, les enseignants d’un établissement primaire lausannois ont été sollicités pour participer à cette étude en répondant à un questionnaire anonyme. Outre le taux d’enseignement des agrès, ce travail vise à comprendre quelles sont les familles de mouvements les plus enseignées et quels sont les engins les plus employés. Enfin, cette étude cherche à identifier quels sont les facteurs qui freinent l’enseignement de cette discipline. Les résultats obtenus révèlent qu’environ la moitié des maîtres généralistes consacrent suffisamment de temps à l’enseignement des agrès. Les familles de mouvement les plus exercées sont la grimpe et les balancements, celles les moins entraînées sont les sauts en profondeur et les appuis sur les bras. Le facteur principal limitant l’enseignement des agrès est le manque de temps lors des leçons d’EPS. Une piste possible pour essayer d’augmenter le temps d’enseignement des agrès ainsi que la fréquence d’enseignement des familles de mouvements les moins exercées, pourrait être l’amélioration de la collaboration entre les collègues du même collège.

description: We have identified a novel phase stability mechanism from the intracavity field-induced self-organization of a fast-moving molecular beam into travelling molecular packets in the bad cavity regime, which is then used to decelerate the molecular packets by feedback-controlled time-varying laser pumps to the cavity. We first applied the linear stability analysis to derive an expression for this self-organization in the adiabatic limit and show that the self-organization of the beam leads to the formation of travelling molecular packets, which in turn function as a dynamic Bragg grating, thus modulating periodically the intracavity field by superradiant scattering of the pump photons. The modulation encodes the position information of the molecular packets into the output of the intracavity field instantaneously. We then applied time-varying laser pumps that are automatically switched by the output of the intracavity field to slow down the molecular packets via a feedback mechanism and found that most of the molecules in the molecular packets are decelerated to zero central velocity after tens of stages. Our cavity-based deceleration proposal works well in the bad cavity regime, which is very different from the conventional cavity- based cooling strategies where a good cavity is preferred. Practical issues in realizing the proposal are also discussed.

description: Understanding the formation history of brightest cluster galaxies is an important topic in galaxy formation. Utilizing the Planck Sunyaev-Zel'dovich cluster catalog, and applying the Ansatz that the most massive halos at one redshift remain among the most massive ones at a slightly later cosmic epoch, we have constructed cluster samples at redshift z~0.4 and z~0.2 that can be statistically regarded as progenitor-descendant pairs. This allows us to study the stellar mass assembly history of BCGs in these massive clusters at late times, finding the degree of growth between the two epochs is likely at only few percent level, which is far lower compared to the prediction from a state-of-the-art semi-analytic galaxy formation model.

description: In the colour string picture with fusion and percolation it is shown that long range azimuthal-rapidity correlations (ridge) can arise from the superposition of many events with exchange of clusters of different number of strings and not from a single event. Relation of the ridge with the flow harmonics coefficients is derived. By direct Monte-Carlo simulations, in the technique previously used to calculate these coefficients, ridge correlations are calculated for AA, pA and pp collisions. The azimuthal anisotropy follows from the assumed quenching of the emitted particles in the strong colour fields inside string clusters. It is confirmed that in pp collisions the ridge structure only appears in rare events with abnormally high multiplicity. Comarison with the experimental data shows a good agreement. Also a good agreement is found for pPb collisions. For AA collisions a reasonable agreement is found for both near-side and away-side angular correlations although it worsens at intermediate angles.

description: Disc stars from the Gaia DR3 RVS catalogue are selected to explore the phase spiral as a function of position in the Galaxy. The data reveal a two-armed phase spiral pattern in the local $z-v_z$ plane inside the solar radius, which appears clearly when colour-coded by $\langle v_R \rangle (z,v_z)$: this is characteristic of a breathing mode that can in principle be produced by in-plane non-axisymmetric perturbations. We note the phase spiral pattern becomes single armed outside the solar radius. When a realistic analytic model with an axisymmetric background potential plus a steadily rotating bar and 2-armed spiral arms as perturbation is used to perform particle test integrations, the pseudo stars get a prominent spiral pattern in the $\langle v_R \rangle$ map in the $x-y$ plane. Additionally, clear breathing mode evidence at a few $\rm{kms}^{-1}$ level can be seen in the $\langle v_z \rangle$ map on the $x-z$ plane, confirming that such breathing modes are non-negligible in the joint presence of a bar and spiral arms. However, no phase-spiral is perceptible in the $(z, v_z)$ plane. When an initial vertical perturbation is added to all pseudo stars to carry out the simulation, the one-armed phase spirals can clearly be seen 500~Myr after the perturbation and gradually disappear inside-out. Finally, we show as a proof of concept how a toy model of a time-varying non-axisymmetric in-plane perturbation with varying amplitude and pattern speed can produce a strong two-armed phase-spiral. We conclude a time-varying strong internal perturbation together with an external vertical perturbation could perhaps explain the transition between the two-armed and one-armed phase-spirals around the Solar radius.

Nous avons arrêté notre choix sur le manuel Français 9e. Livre Uniqueparu en 2009 aux éditions Hatier. Notre étude a pour but de déterminer dans quelle mesure cet ouvrage rend compte des avancées du féminisme, mais également d'une image contemporaine et progressiste de la représentation des rôles et des sexes. Cette approche s'inscrit dans le champ des études genre et met en perspective la part de ségrégation sexuelle et de stéréotypes présents dans l'iconographie et les textes cités dans notre manuel. Une double lecture, à la fois quantitative et qualitative des textes et des illustrations, donnera naissance à un commentaire sur la division sexuelle des tâches et des représentations, contribuant à l'élaboration d'un discours autour du sexisme et de sa présence en milieu scolaire.

description: An excavation by Thames Valley Archaeological Services on land to the south of Huntingdon Road, Thrapston, examined part of a late Bronze Age circular enclosure ditch with some evidence of an internal bank. Radiocarbon dating indicates that the ditch was dug during the first quarter of the 1st millennium BC. The feature has been interpreted as a mini-hillfort or elite residence of type particular eastern England. The largest pottery collection in the county for this period was recovered, together with an important assemblage of animal bones. Late Bronze Age and late Iron Age pits were found both inside and outside the circuit of the ditch and a number of late Iron Age working hollows were also discovered. Medieval ridge and furrow overlay the Prehistoric deposits and some modern quarrying and pit digging had disturbed parts of the site.

description: Mixed valence rare-earth samarium compounds SmX (X=Se,Te) have been recently proposed as candidate materials for use in high-speed, low-power digital switches driven by stress induced changes of resistivity. At room temperature these materials exhibit a pressure driven insulator-to-metal transition with resistivity decreasing by up to 7 orders of magnitude over a small pressure range. Thus, the application of only a few GPa's to the piezoresistor (SmX) allows the switching device to perform complex logic. Here we study from first principles the electronic properties of these compounds under uniaxial strain and discuss the consequences on carrier transport. The changes in the band structure show that the piezoresistive response is mostly governed by the reduction of band gap with strain. Furthermore, it becomes optimal when the Fermi level is pinned near the localized valence band. The piezoresistive effect under uniaxial strain which must be taken into account in thin films and other systems with reduced dimensionality is also quantified. Under uniaxial strain we find that the piezoresistive response can be substantially larger than in the isotropic case. Analysis of complex band structure of SmSe yields a tunneling length of the order of 1 nm. The results suggest that the conduction mechanism governing the piezoresistive effect in bulk, i.e.~thermal promotion of electrons, should still be dominant in few-nanometer-thick films.

description: We study the impact of kinks on the cosmic microwave background (CMB) anisotropies generated by cosmic string networks. To do so, we extend the Unconnected Segment Model to describe the stress-energy tensor of a network of cosmic strings with kinks and implement this extension in CMBACT to compute the CMB anisotropies generated by these wiggly string networks. Our results show that the inclusion of kinks leads, in general, to an enhancement of the temperature and polarization angular power spectra, when compared to those generated by cosmic string networks without small-scale structure with the same energy density, on scales corresponding to the distance between kinks. This enhancement, that is more prominent in the case of the temperature anisotropies, is essentially caused by a significant increase of the vector-mode anisotropies, since kinks, due to their shape, generate vortical motions of matter -- a phenomenon that is not taken into account when resorting to an effective description of wiggly cosmic strings.

description: Au centre de la formation des enseignants, on trouve deux éléments constitutifs: les didactiques et les sciences de l’éducation. Dans ces domaines, le rôle des pédagogies est notamment de proposer une relation maître-élève favorable à l’apprentissage. Le but est que les élèves élaborent des connaissances, des savoir-faire et des savoir-être. Le travail de groupes s’inscrit dans un panel de pédagogies distinctes. Les pédagogies collaborative et coopérative sont introduites dans ce mémoire pour retracer la genèse de la pratique des travaux de groupes. Il en ressort l’importance de la construction du sens par les élèves lors des apprentissages. Tout en privilégiant la relation élèves à élèves, les travaux de groupes favorisent un apprentissage auquel les élèves attribuent activement et durablement un sens. Face aux avantages théoriques des travaux de groupes, il est intéressant de considérer les propos des enseignants quant à leur pratique de ces derniers. Qu’en est-il dans la réalité de la pratique enseignante en matière de travaux de groupes ? Cette question constitue le moteur de cette recherche. Si les enseignants pratiquent le travail de groupes, est-ce grâce à leur formation ? S’ils ne pratiquent guère de travaux de groupes est-ce à cause de la difficulté de maintenir la discipline ? Ainsi, nous interrogeons les origines de la motivation ou de l’abandon chez les enseignants de la pratique de travaux de groupes. Les données travaillées dans ce mémoire sont issues d’un questionnaire envoyé à deux établissements scolaires vaudois et de sept entretiens semi-directifs avec des enseignants vaudois. L’intérêt de cette étude est de recueillir des données concernant l’importance du travail de groupes accordée par les enseignants dans la planification annuelle de leurs séquences. Aussi désirons-nous trouver les éléments qui montrent comment les enseignants mobilisent leur parcours de formation dans leur pratique enseignante.

description: This survey brings together all the available evidence of early iron smelting in the Rockingham Forest region of Northamptonshire from documentary sources, the county SMR and recent fieldwork. The survey looks at the history of the Rockingham Forest woodland together with the underlying iron bearing strata. Documentary evidence for iron smelting within the forest is discussed, along with the field evidence, furnace groups, and furnace types. Early/middle and late Saxon smelting is duly examined as is the importance of the Fineshade valley as a centre of iron smelting in the forest, finally, the gazetteer sets out the known evidence. Clearly, one of the most important issue sin the study of iron smelting today is the dating of smelting sites. In order to address this problem a number of slag patches and mounds were sampled and charcoal obtained for C14 dating. Work began with the sampling of an undated slag mound in the corner of Bulwick parish, a charcoal sample from this giving an early/middle Saxon date. The success of this investigation prompted similar sampling of three adjacent slag mounds in Gretton parish resulting in three late Saxon dates. Further to this an examination was undertaken of the Fineshade/Laxton valley, where a large Roman iron production site was excavated by Dennis Jackson in 1985, and a number of undated slag sites were known to exist. Charcoal samples obtained from six of these sites produced radiocarbon dates ranging from the 5th century AD to the 12th century. In the summer of 2000, a magnetometer survey was carried out over a well preserved example of a smelting site at Cendry Holme in the Fineshade valley, followed up by trial trenching to confirm the results and the planning of a furnace, which gave a C14 date of AD 890-1030. A smelting site was also investigated in Oundle Wood and given a late Saxon date. In Easton Hornstock Wood two sites, part of a previously unknown complex of sites, were dated to the early/middle Saxon period.

description: Two predominantly early/middle to middle Iron Age sites 2.5km apart, both part of a linear cropmark system along a valley side running towards the River Nene, Northamptonshire, were partially excavated at Sywell Aerodrome (1996) and at Ecton (1992/3) prior to the construction of offices and a water pipeline respectively. The earliest feature uncovered was at Ecton where a single late Bronze Age/early Iron Age pit contained two pottery vessels. Apart from this feature, occupation seems contemporary with the Sywell site dating between the 5th or 4th to 1st centuries BC compared with the Ecton site dating from the 4th to 2nd centuries BC. Early Iron Age pottery was recovered from a single linear ditch at Sywell. The early/middle Iron Age was represented by three pits found on the extreme north-east of the excavation, which may signify a focus of occupation in this period outside the area of excavation. The middle Iron Age formed the vast majority of the evidence and comprised parts of two enclosures, a four-post structure, and a scatter of pits all truncated by subsequent cultivation and presumably part of a single unenclosed farmstead c.0.5 hectares in area identified from more extensive crop marks. At Ecton, truncated features were excavated for 240 m along the 15 m wide water pipeline corridor with deposits ending abruptly on the northern side and quarried away on the southern side. The features comprised a group of five small circular enclosures and surrounding pits, together with rectilinear enclosures and other associated pits, and two further small circular features nearby, to the north. In all, this Ecton site was part of an extensive settlement. A section through a separate cropmark site was examined when the pipe trench crossed the edge of a new set of enclosures 300 m to the south west of the Ecton site. Sections through two parallel ditches and the western side a rectangular enclosure recovered no dating evidence.

description: The area of a new swimming pool at the Moat House Hotel, Northampton, adjacent to King Street, was excavated in advance of development. Earlier deposits had been severely truncated but two pits of 10th century date attested to late Saxon activity in this north-eastern corner of the early town. In the mid-13th century there was a distinct change in use, with the digging of much larger pits, presumably as quarry pits to obtain ironstone for building. They had been infilled by the 14th century, when one was sealed a laid stone surface. By the mid-17th century a garden soil had accumulated over this area, when the site lay to the rear of properties fronting onto King Street. A steady increase in activity from the late 17th century onward relates to the progressive development of this frontage. The western half of the site was a yard until the late 19th century; it contained three wells and several pits. The eastern half of the site was occupied by the rear wing of the former No. 12 King Street.

description: Two closely connected sites at Southwick in Northamptonshire have produced evidence to show that the village had a thriving iron-smelting industry in the 10th century. A medieval stone hall dating from the mid-13th century may have been a manse owned by St. Marys Priory, Huntingdon. This building later served as a small non-ferrous metal workshop with hearths and a casting pit and was subsequently converted into a kitchen and brewhouse before being relegated to use as an outbuilding for the 16th century Vicarage Farm.

description: Dès la naissance, l’humain communique grâce à l’expression non verbale pour faire passer des messages et se faire comprendre. La présente étude a pour objectifs de rendre compte aux enseignants de l’expression des comportements non verbaux et de la représentation qu’ils en ont dans la mise au travail de la classe. Le début de leçon s’avère primordial en termes de gestion de classe, c’est pourquoi, notre étude se porte exclusivement sur l’observation et l’analyse des comportements non verbaux durant les premières minutes de cours. Pour répondre à nos interrogations, quatre enseignants volontaires ont été filmés en début de période puis ont été interviewés. Une analyse des films a été effectuée selon deux grilles d’observation préalablement établies et enfin, les enseignants filmés ont été confrontés à leur image et interviewés. Les indicateurs non verbaux observés sont le regard, les expressions des émotions, les mimiques du visage, le déplacement, la position, la voix et le toucher. Les enseignants ont ainsi pris conscience de leur langage non verbal et de l’impact de ce dernier sur leur pédagogie. Ils ont également formulé leur perception de leur communication non verbale. Notre étude a révélé que trois des quatre cas étudiés ont une perception de leur comportement non verbal en adéquation avec la réalité factuelle observée lors de notre observation sur le terrain. Le dernier cas s’est vu moins verbaliser ses perceptions liées aux éléments non verbaux et de gestion de classe, ce qui nous a amené à en déduire que l’enseignant se voit moins en phase et conscient de sa communication non verbale. L’expérience préalable, la maîtrise ou non d’une classe ainsi que la sensibilisation à cette thématique durant les études pédagogiques sont des facteurs qui selon nous ont une influence sur la perception de sa propre communication non verbale.

description: The merger remnant of a binary neutron star coalescence is initially strongly differentially rotating. Some properties of these remnants can be accurately modeled through building equilibrium neutron star models. In the present paper, we study how a modification of general relativity, namely scalar-tensor theory with a massive scalar field, will alter the picture. In contrast to previous studies, we implement a realistic phenomenological differential rotational law which allows for neutron star models to attain maximal angular velocity away from the center. We find that solutions with much higher masses and angular momenta exist in scalar-tensor theory compared to general relativity. They keep their quasi-spherical energy-density distribution for significantly higher values of the angular momentum before transitioning to quasi-toroidal models, in contrast to pure general relativity. Constructing such neutron star solutions is the first step to our final goal that is studying how scalarization alters the stability and gravitational wave emission of post-merger remnants.

Chargés d’enseigner une multitude de branches, les généralistes ne bénéficient que d’une formation de base pour enseigner l’EPS, bien moins complète que celle reçue par leurs collègues spécialistes. Ainsi, ce travail s’intéresse aux compétences et ressources dont disposent ces maîtres pour enseigner l’EPS, dans le but de définir leurs besoins et proposer quelques pistes d’action pouvant favoriser leur formation et leur enseignement. Les données ont été recueillies auprès de 6 enseignants généralistes d’un établissement vaudois. Les résultats indiquent qu’une grande majorité d’entre eux ne se sent pas suffisamment formée pour enseigner l’EPS. Il ressort également que les formations reçues étaient davantage axées sur l’enseignant aux petits degrés primaires et non adaptées au public de 5 et 6e années. Les généralistes interrogés affirment avoir besoin d’aide surtout pour enseigner les domaines de l’EPS où ils sont les moins compétents ou qu’ils n’ont pas abordés en formation. D’autre part, ils seraient favorables à l’instauration de l’animation pédagogique en 5 et 6e années, de manière à bénéficier des compétences et des conseils experts de maîtres spécialistes. Tous les généralistes interrogés perçoivent également une utilité à suivre des formations thématiques de manière à combler certaines lacunes et se former davantage. Ils souhaiteraient pouvoir sélectionner des formations parmi un éventail de thèmes relatifs à l’EPS, de manière à choisir les domaines où ils ont le plus besoin de se former. L’exemple des formations thématiques organisées à l’interne de l’établissement concerné apparaît comme une piste d’action intéressante à mettre en place, permettant de les cibler en fonction des besoins des généralistes. D’autre part, des formations internes représentent l’occasion de collaborer en équipe, où l’expérience et les compétences des maîtres spécialistes en EPS pouvant grandement bénéficier aux généralistes. Finalement, il ressort que les enseignants les moins expérimentés sont également ceux qui ont le plus de besoins.

description: A very sensitive X-ray investigation of the giant HII region N11 in the LMC was performed using the Chandra X-ray Observatory. The 300ks observation reveals X-ray sources with luminosities down to 10^32 erg/s, increasing by more than a factor of 5 the number of known point sources in the field. Amongst these detections are 13 massive stars (3 compact groups of massive stars, 9 O-stars and one early B-star) with log(Lx/Lbol)~-6.5 to -7, which may suggest that they are highly magnetic or colliding wind systems. On the other hand, the stacked signal for regions corresponding to undetected O-stars yields log(Lx/Lbol)~-7.3, i.e., an emission level comparable to similar Galactic stars despite the lower metallicity. Other point sources coincide with 11 foreground stars, 6 late-B/A stars in N11, and many background objects. This observation also uncovers the extent and detailed spatial properties of the soft, diffuse emission regions but the presence of some hotter plasma in their spectra suggests contamination by the unresolved stellar population.

description: L’éducation physique est une branche qui se différencie des autres matières enseignées à l’école. Elle a comme but premier le développement du système moteur, met en action le corps dans son entier et implique une organisation dans l’espace bien différente des cours enseignés en salle de classe. La communication, le message à faire passer aux élèves se différencient aussi du langage communément utilisé dans les matières autres que l’éducation physique. L’engagement important du corps, le mouvement et le bruit sont des paramètres qui encouragent la transmission d’un message autrement que par les mots et la parole. Le corps, le visage et le regard s’expriment et se font comprendre sans rien faire. La force des expressions corporelles est telle qu’elles prennent le dessus sur le langage verbal. Les auteures de ce travail se sont intéressées au regard que les élèves portent sur l’enseignant d’EPS, à savoir s’ils attachent de l’importance à l’apparence, ou s’ils sont sensibles à un changement d’humeur de leur professeur. A l’aide d’un questionnaire, les élèves ont pu s’exprimer et ont pu nous faire passer un message. Qu’attendent-ils d’un maître d’EPS ? Préfèrent-ils un enseignant musclé, une enseignante sexy ou un maître de sport comique ? Le maître quant à lui a-t-il conscience de l’image qu’il renvoie? Nous sous-estimons certainement trop l’influence du langage non verbal, particulièrement dans une discipline où le corps est modèle, le corps est référence et le corps est roi. Les élèves de l’école secondaire nous le démontrent.

description: We investigate a control of the motion of localized structures of light by means of delay feedback in the transverse section of a broad area nonlinear optical system. The delayed feedback is found to induce a spontaneous motion of a solitary localized structure that is stationary and stable in the absence of feedback. We focus our analysis on an experimentally relevant system namely the Vertical-Cavity Surface-Emitting Laser (VCSEL). In the absence of the delay feedback we present experimental evidence of stationary localized structures in a 80 $μ$m aperture VCSEL. The spontaneous formation of localized structures takes place above the lasing threshold and under optical injection. Then, we consider the effect of the time-delayed optical feedback and investigate analytically the role of the phase of the feedback and the carrier lifetime on the self-mobility properties of the localized structures. We show that these two parameters affect strongly the space time dynamics of two-dimensional localized structures. We derive an analytical formula for the threshold associated with drift instability of localized structures and a normal form equation describing the slow time evolution of the speed of the moving structure.

description: Tout enseignant a probablement dû faire face à un manque de motivation chez ses élèves. Il est pourtant vrai qu’un élève investi démontrera probablement plus de performances dans son parcours scolaire, quelle que soit la branche. La notion de motivation est donc essentielle dans une perspective de l’enseignement cherchant à susciter le désir d’apprendre chez les élèves. La démarche adoptée ici a permis de mettre en évidence un certain nombre de facteurs inhérents à la motivation des élèves en français. Un questionnaire a été proposé aux étudiants de la HEP-Vaud concernant la motivation supposée de leurs élèves en français. Puis, dans l'étude principale, un questionnaire similaire a été rempli par les élèves de deux classes : une 7ème VSG et une 9ème VSO. Les intitulés portaient sur les activités du français, ses concepts ainsi que l'attitude de l'enseignant. L'analyse des résultats a permis de mettre en évidence trois différences de motivation principales entre ces deux classes. Tout d'abord une motivation divergente en fonction de l'âge des élèves dans des activités comme la poésie ou la lecture à haute voix. Ensuite, des oppositions face à la manière de faire des enseignants. Par exemple, dans leur pratique des activités de vocabulaire ou de conjugaison. Enfin, un écart dans la motivation en fonction de la voie d'orientation au regard de la dévalorisation de leurs capacités et de la mauvaise perception par les élèves de leurs propres ressources.

description: Construction industry is one of the main sectors that provide important ingredients for the development of an economy. Construction is a tool through which a society achieves its goals of urban and rural development. However it is becoming more complex because of the sophistication of the construction process itself and the large number of parties involved in the construction process. This eventually leads to delay in the completion of the project. Construction delay defined as “time over run either beyond completion date specified in a contract or beyond the date that parties agree upon for delivery of a project.” Delay in construction project completion is a global phenomenon that occurs in the construction industry and considered as one of the most common problems causing a multitude of negative effects on the project and its participating parties especially where the government projects are concerned. The basic aspiration of this research is to identify the main causes and effects of construction project delay, and provide suggestions to minimize delays in the construction of Technical and Vocational Education and Training Building projects under Oromiya TVET Bureau. This study uses literature review and conduct a survey to investigate delay causes and its effects. The total population of the study was 82 construction project operators: clients, contractors and consultants, those which play role in the construction of 10 TVET projects which are constructed from 2015 to 2020 from which 68 samples were drawn by stratified sampling. From the 82 population 68 samples were taken because few members of project operators were not available in their former organization and it takes time to get them. In collecting the required data, questionnaire, interviews and observation check list were the main instruments to be used. Data were analyzed using descriptive statistics with the help of Statistical Packages for Social Science (SPSS). In the study 26 main influential factors that cause delay and two main effects are identified. Finally the study came up with recommendation that all parties in the construction better have integrated plan, consultant has to prepare properly detailed contract document, drawing and specification and financial problem of contractor and client has to be improved

description: Fotheringhay is a village probably best known for its castle and its tragic association with the execution of Mary, Queen of Scots. The parish church of St. Mary's and All Saints at Fotheringhay, once the dynastic mausoleum of the House of York, now consists of a magnificent perpendicular nave, all that is left of the 15th century Collegiate Church of the Annunciation and All Saints. Installation of new bells in 1990 initiated the discovery ad subsequent excavation of a forgotten ossuary beneath the floor of the north porch. Material recovered indicated that the room was contemporary with the 15th century building and included a large amount of the original stained window glass. The room had been filled in at the beginning of the 19th century during restoration. A large carved ashlar block removed in the excavation, is of smaller dimensions than those of the remaining church and may be the only known remnant of the claustral buildings. Documentary evidence has been found which places the school and masters house to the north of the demolished collegiate choir.

description: We study the focusing nonlinear Schrödinger equation in the $L^2$-supercritical regime with finite energy and finite variance initial data. We investigate solutions above the energy (or mass-energy) threshold. In our first result, we extend the known scattering versus blow-up dichotomy above that threshold for finite variance solutions in the energy-subcritical and energy-critical regimes, obtaining scattering and blow-up criteria for solutions with arbitrarily large mass and energy. As a consequence, we characterize the behavior of the ground state initial data modulated by a quadratic phase. Our second result gives two blow up criteria, which are also applicable in the energy-supercritical NLS setting. We finish with various examples illustrating our results.

description: The logarithmic law of the wall, joining the inner, near-wall mean velocity profile (abbreviated MVP) in wall-bounded turbulent flows to the outer region, has been a permanent fixture of turbulence research for over hundred years, but there is still no general agreement on the value of the pre-factor, the inverse of the Kármán ``constant'' $κ$, or on its universality. The choice diagnostic tool to locate logarithmic parts of the MVP is to look for regions where the indicator function $Ξ$ (equal to the wall-normal coordinate $y^+$ times the mean velocity derivative $\dd U^+/\dd y^+$) is constant. In pressure driven flows however, such as channel and pipe flows, $Ξ$ is significantly affected by a term proportional to the wall-normal coordinate, of order $\mathcal{O}(\Reytau^{-1})$ in the inner expansion, but moving up across the overlap to the leading $\mathcal{O}(1)$ in the outer expansion. Here we show that, due to this linear overlap term, $\Reytau$'s well beyond $10^5$ are required to produce one decade of near constant $Ξ$ in channels and pipes. The problem is resolved by considering the common part of the inner asymptotic expansion carried to $\mathcal{O}(\Reytau^{-1})$, and the leading order of the outer expansion. This common part contains a \textit{superposition} of the log law and a linear term $S_0 \,y^+\Reytau^{-1}$, and corresponds to the linear part of $Ξ$, which, in channel and pipe, is concealed up to $y^+ \approx 500-1000$ by terms of the inner expansion. A new and robust method is devised to simultaneously determine $κ$ and $S_0$ in pressure driven flows at currently accessible $\Reytau$'s, yielding $κ$'s which are consistent with the $κ$'s deduced from the Reynolds number dependence of centerline velocities. A comparison with the zero-pressure-gradient turbulent boundary layer further clarifies the issues.
