We present several possible forms of mathematical competitions for University students. One of them is Blitz Mathematical Olympiad. It is a team competition, when all teams receive the same problem and are allotted 10-15 minutes to come up with a solution. This cycle is repeated 6-8 times with different problems. Modern Internet technologies allow us to organize Blitz Mathematical Olympiads for the teams which are in different cities and even countries.

Modern Internet technologies open new possibilities in a wide spectrum of traditional methods, used in mathematical education. One of the areas, where these technologies can be efficiently used, is an organization of mathematical competitions. Contestants can stay in their schools or universities in different cities and even different countries and try to solve as many mathematical problems as possible and then submit their solutions to organizers through the Internet. Simple Internet technologies supply audio and video connection between participants and organizers in a time of the competitions.

Thesis (MScSportSc)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The purpose of this qualitative-quantitative study was to describe the exercise intensity and predictors of performance of a multi-stage mountain bike (MTB) race (2014 Absa Cape Epic) lasting 8 days. Twenty-three amateur mountain bikers (age 39 ± 9 years, height 178.8 ± 8.2 cm, body mass 74.7 ± 9.1 kg, VO2max 54 ± 7 ml.kg-1.min-1) who completed the 2014 Absa Cape Epic were involved in the study. The participants were divided into two groups according to their MTB experience. The experienced group included participants who previously completed more than three 3-day multi-stage MTB events and the novices group included those who has completed less than 3-day multi-stage MTB events. Prior to the event the participants completed a maximal aerobic cycling test and a simulated 40 km time trial (TT). The maximal aerobic test was used to determine 3 work intensity zones based on heart rate (HR) corresponding to blood lactate thresholds (LT: increase in blood lactate concentration of 1 mmol.l-1 above baseline values and the onset of blood lactate accumulation (OBLA), a fixed blood lactate concentration of 4 mmol.l-1). There were no statistically significant differences in the physical, physiological and performance variables measured in the laboratory between the two groups. The exercise intensity during the Cape Epic was measured using telemetric HR monitoring sets. RPE values were noted after each stage of the race. The mean HR was 88.1 ± 5.3% (experienced) and 84.2 ± 11.0% (novices) of maximal HR during the race or 88.9 ± 3.5% (experienced) and 85.9 ± 10.6 (novices) of laboratory determined maximum HR. More time was spent in the “low” HR zone (43.1 % vs 58.5 %, respectively), while only a small amount of time was spent in the “hard” HR zone (7.4% and 6.1%, respectively). The experienced group spent statistically significantly more time in the “moderate” HR zone compared to the novices group (49.5 % vs. 35.4 %). The experienced group performed significantly better during the event compared to the novices group in both the total event time (P = 0.004) and the general classification (P = 0.01). Relative and absolute power output (PO) at OBLA (P = 0.01 and 0.02, respectively) were statistically significant predictors of total event time, while relative peak power output was a significant predictor of general classification for the event (P = 0.02) . The total TT time was a significant predictor of average event HR (P = 0.03). This study showed that this MTB stage race is physiologically very demanding and requires cyclists to have excellent endurance capacity, as well as strength and power. The parameters from the maximal aerobic capacity test correlated better with outdoor performance than parameters from the simulated 40 km TT. Therefore the standard maximal aerobic capacity test are sufficient for testing mountain bikers and sport scientists can continue using this test to prescribe exercise intensity zones for training and events. / AFRIKAANSE OPSOMMING: Die doel van hierdie kwalitatiewe-kwantitatiewe studie was om die oefeningsintensiteit en voorspellers van prestasie tydens ‘n multi-dag bergfiets kompetisie (Absa Cape Epic) van 8 dae lank te bepaal. Drie-en-twintig bergfietsryers (ouderdom 39 ± 9 jaar, lengte 178.8 ± 8.2 cm, liggaamsmassa 74.7 ± 9.1 kg, VO2maks 54 ± 7 ml.kg-1.min-1) wat die 2014 Absa Cape Epic voltooi het, het aan die studie deelgeneem. Die deelnemers is in twee groepe verdeel volgens hulle ervaring in multi-dag bergfiets kompetisies. Die ervare groep was al die deelnemers wat meer as drie 3-dae multi-dag bergfiets kompetisies voltooi het. Die onervare groep was al die deelnemers wat minder as drie 3-dag multi-dag bergfiets kompetisies voltooi het. Voor die kompetisie het al die deelnemers ‘n maksimale aërobiese toets en ‘n gesimuleerde 40 km tydtoets in die laboratorium voltooi. Die maksimale aërobiese toets is gebruik om drie werk intensiteit sones volgens die hartspoed te bepaal, naamlik die hartspoed by die laktaatdraaipunt(‘n toename in bloed [laktaat] van 1 mmol.l-1 bo die basislynwaardes) en die hartspoed by die aanvang van bloedlaktaat akkummulasie (‘n vaste bloed [laktaat] waarde van 4 mmol.l-1). Daar was geen statisties betekenisvolle verskille in die fisiese, fisiologiese en prestasie veranderlikes tussen die twee groepe nie. Die oefeningsintensiteit tydens die Cape Epic was gemeet deur gebruik te maak van hartspoedmonitors. Die RPE waardes was aan die einde van elke skof genoteer. Die gemiddelde hartspoed was 88.1 ± 5.3 % (ervare) en 84.2 ± 11.0 % (onervare) van maksimale kompetisie hartspoed, of 88.9 ± 3.5 % (ervare) en 85.9 ± 10.6 % (onervare) van die maksimale hartspoed soos in die laboratorium gemeet. Die fietsryers het meer tyd spandeer in die “lae” hartspoed sone (43.1 % vs 58.5 %, onderskeidelik), in vergelyking met die “moeilike” hartspoed sone (7.4 % vs 6.1 %, onderskeidelik). Die ervare groep het statisties betekenisvol meer tyd in die “matige” hartspoed sone spandeer (49.5 % vs. 35.4 %) in vergelyking met die onervere groep. Die ervare groep het beter presteer tydens die kompetisie vir beide totale kompetisie tyd (P = 0.004) en algehele klassifikasie (P = 0.01). Relatiewe en absolute krag by aanvang van bloed laktaat akkumulasie was statisties betekenisvolle voorspellers van totale kompetisie tyd (P = 0.01 en 0.02, onderskeidelik), terwyl maksimale krag ‘n statisties betekenisvolle voorspeller was van algehele klassifikasie in die kompetisie (P = 0.02). Die totale tydtoets tyd was ‘n statisties betekenisvolle voorspeller van gemiddelde hartspoed tydens die kompetisie. Die studie het gewys dat hierdie multi-dag bergfiets kompetisie fisiologies baie uitdagend is en dat fietsryers uistekende uithouvermoë kapasiteit, sowel as krag en plofkrag moet besit. Die veranderlikes van die maksimale aërobiese toets het beter met prestasie in die veld gekorreleer as die veranderlikes van die gesimuleerde 40 km tydtoets. Daar word dus afgelei dat die standaard maksimale aërobiese toets voldoende is vir die toetsing van bergfietsryers en sportwetenskaplikes kan aanhou om hierdie toets te gebruik om oefeningsintensiteit sones voor te skryf vir oefensessies en kompetisies.

Il existe somme toute peu de théories du projet offrant une modélisation construite à partir de la complexité et de la diversité du projet d’architecture. Pourtant,certaines situations rassemblant parfois plusieurs dizaines de projets s’offrent d’elles-mêmes comme des situations comparatives et expérimentales : les concours d’architecture, d’urbanisme et de paysage. Le Laboratoire d’étude de l’architecture potentielle de l’Université de Montréal (Aménagement), après avoir développé un système d’archivage numérique des concours canadiens, a entrepris, avec le soutien du Groupement d’intérêt public « Europe des projets architecturaux et urbains », de développer la base de données documentaire des concours d’idées Europan. Au-delà des questions d’archivage numérique, se profilent clairement des possibilités de théorisation s’appuyant sur les logiques d’une base de données, en particulier sur la constitution du diagramme entités et relations, modélisation indispensable à sa traduction informatique. Cette recherche entreprend une première mise à jour de ces éléments conceptuels et tend à montrer que la base de données est un véritable modèle théorique du projet ouvrant sur de nouvelles avenues de recherche et de connaissance. / There are not many theories of project offering a modeling constructed from the complexity and diversity of the architecture project. However, certain situations bringing together dozens of projects, present themselves as comparable and experimental situations: architectural, urban and landscape competitions. The Laboratoire d'étude de l'architecture potentielle from the Université de Montréal (Environmental Design), having developed a system of digital archiving for Canadian competitions, has undertaken, with the support of Groupement d'intérêt public “Europe des projets architecturaux et urbains”, the development of a database comprised of the documentation of competition ideas of Europan. Beyond the issues of digital archiving, there are clearly theorizing possibilities based on the logic of a database, particularly on the structure of the entity/relationship diagram, an indispensable modeling necessary for its computer translation. This research is undertaking a first update of these conceptual elements and suggests that the database is a theoretical model of the project opening up new venues for research and knowledge.

Lentil (Lens culinaris Med.) is an important component of the human diet in the world, but in the meantime, Europe produces only 26% of the lentils it consumes. This is partly due to strong agronomic weaknesses that reduce yield such as lodging, bruchid beetles and weeds, especially in organic farming. Intercropping, the simultaneous growing of two or more species in the same field is tested here as an option to reduce these drawbacks and develop organic lentil production. The aims of this thesis were to (1) assess the potential of lentil-spring wheat intercrops to produce organic lentil, (2) understand the mechanisms that explain their performances, and (3) evaluate the profitability of such intercrops. A two-year field experiment was carried out in southwestern France in 2015 and 2016 under organic farming rules. Four lentil and two wheat cultivars were grown as sole crops and intercrops in multiple additive and substitutive designs. Our results showed that the total intercrop attainable grain yield was higher than the mean of sole crops. Yet, lentil yield in intercrop was lower than in sole crop as the result of a strong competition for resources from wheat in early lentil growth stages reducing the number of branches per plant of lentil. This led to lower gross margins of intercrops. However, lentil lodging was strongly reduced in intercrops thus its mechanical harvest efficiency increased. This led to similar mechanically harvested yields of lentil in intercrop and sole crop. Consequently, after mechanical harvest and grain cleaning, the marketable gross margin of intercrops was higher than that of sole crops. Our results suggest that (1) intercrop had no effect on bruchids, (2) the most effective intercrop is when lentil is at sole crop density and wheat at 15-20%, (3) intercrop performance is due to complementary use of N pools through legume N2 fixation and (4) the intensity of interspecific interactions depends on year, wheat density and genotypes. Our work indicates that lentil-spring wheat intercrop can develop organic lentil production but a better understanding of Genotype x Environment x Cropping system interactions may be useful to design optimized managements.

« Ça se fait pas ! ». La norme à l’école est marquée par des nuances et des ambivalences, sources d’incompréhensions et de concurrences, participant à sa fluctuation. L’élève joue un rôle premier devant l’enseignant, acteur, créateur et agent de la norme. La norme en classe présente un caractère inégal, binaire, ambigu, indéterminé et implicite, avec le reflet illusoire d’être partagée par l’élève et l’enseignant. La norme devient homogène pour eux face à une infraction identifiée, majoritairement comme abstention. Dans l’interdépendance entre norme, déviance et acceptation, les limites de l’acceptable en classe se tracent avant tout par rapport à la transgression. L’intrusion de l’affect accentue les fluctuations de la norme et influence les limites du conforme. La norme en classe se décline en situation au sein de l’interaction, dans la dialectique entre conscience et pratique de la norme, qui participe au processus de normalisation. Le registre comportemental est organisateur de la norme et facteur de fluctuations, modulant l’acceptation ou engageant vers la transgression. Les perspectives déontique et pragmatique se concurrencent. Dans la rivalité entre perspectives individuelle et sociale, les besoins sont des facteurs de l’acceptation de la norme, pour chercher à les satisfaire. L’interdépendance entre norme et besoins contribue au processus de normalisation et perturbe l’élève et l’enseignant dans leur rapport à la norme. Les normes en classe se conjuguent ou rivalisent au sein d’un système dynamique et enchevêtré, troublé par les besoins, dont la (l’in)cohérence module le rapport au conforme et engage les acteurs de l’école vers la transgression ou l’acceptation. / “It’s just not done !”. The norm at school is marked by nuances and ambivalences, it is the source of incomprehension and competitions participating in its fluctuation. The student plays the first role in front of the teacher, actor, creator and agent of the norm. The norm provides for an uneven, binary, ambiguous, indefinite and implicit character, offering the imaginary reflection to be shared by the students and teachers. The norm becomes homogeneous for them when confronted with an identified breach, mainly as abstention. In the interdependence animating normality, abnormality and acceptance, the limits of what is considered acceptable at school trace above all with regard to transgression. The intrusion of the affect stresses the fluctuations in the norm and influences the limits of the standard-compliant. The norm is articulated around the situation within the interaction, in the dialectic between consciousness and practice of the norm, which participates in the process of normalization. The behavioral register is the organizer of the norm itself, modulating the acceptance or committing towards the transgression. The deontic and pragmatic perspectives compete amongst themselves. Requirements are factors of the norm’s acceptance, to try to satisfy them. The interdependence between the norm and the requirements participates in the process of normalization and disrupts both students and teachers in their relationship with the norm. The norms at school combine or compete within a system both dynamic and muddled, disturbed by the requirements of coherence which modulate the relationship in compliance and commits school’s actors towards either transgression or acceptance.

Insbesondere für kleine und mittlere Softwareunternehmen stellen die Erhöhung der eigenen Innovationskraft und -geschwindigkeit entscheidende Überlebensfragen dar. Der heute als hierfür wichtig hervorgehobene Ansatz der „Open Innovation“ hat sich in der Softwareentwicklungsbrache bislang jedoch kaum durchgesetzt, obwohl den Kunden bzw. Anwendern von Softwareprodukten wegen ihres im Umgang mit den Softwareprodukten gewonnenen Erfahrungswissens ein großes Innovationspotenzial nachgesagt werden kann. Die Durchführung von Ideenwettbewerben stellt in diesem Zusammenhang eine leicht adaptierbare und kostengünstige Methode der Kundenintegration dar. Ziel dieses Beitrages ist, IT-gestützte Ideenwettbewerbe als ein vielversprechendes theoretisches Konzept zur Integration von Kunden in das Innovationsmanagement von Softwareunternehmen vorzustellen.
