Ultra-high temperature metamorphism recorded in Fe-rich olivine-bearing migmatite from the Khondalite Belt, North China Craton

2018

International audience; We document the first occurrence of Fe‐rich olivine‐bearing migmatitic metapelite in the Khondalite Belt, North China Craton. Petrological analyses revealed two exotic assemblages of orthopyroxene+spinel+olivine and orthopyroxene+spinel+cordierite. Phase relation modelling suggests that these assemblages are diagnostic of ultra‐high temperature (UHT) metamorphism in the Fe‐rich system, with temperatures from 1,000 to 1,050°C at 0.6 GPa. U–Th–Pb SIMS analyses on zircon reveal a similar age of c. 1.92 Ga for the olivine‐bearing migmatite and an adjacent gabbronoritic intrusion that is therefore identified as the heat source for the UHT metamorphism. These results, coup…

Læringspotensial i en digital interaktiv matematikkundervisning : en analyse av læringspotensialet i geometriundervisningen på 8. trinn med utstrakt …

2016

Masteroppgave matematikkdidaktikk – Universitetet i Agder 2016 The theme of this master thesis is learning potential in mathematical tasks designed for geometry teaching in GeoGebra in 8th grade. This thesis is written in connection to the project Digital interactive mathematics teaching (DIM), where the goal is to create innovative mathematics teaching by using digital tools in a pedagogic context. Previous research has documented that students learning outcome of the teaching is largely influenced and limited by the tasks that are given. In this context analysis of the tasks learning potential is particular interesting. Therefore, my research question is: What learning potential is it in …

How the sociological environement of university residence affects making friendship and students' academic success

2013

By means of a theoretical model, this research investigated how the socioecological environment of university residence affects making friendship in the latter and students' academic success. The model contain four physical-environmental characteristics (distal variables): type of university residence (traditional, conventional), the location (outside or in the city center), and percentages of girls and of advantaged students. It also includes three social climate dimensions of university residence: Order and organization, Cohesion, and Open-mindedness (proximal variables, Bennacer, 2005). Making friendship and students' academic success were estimated, respectively, by following items: "Di…

Developing Students Well-Being and Engagement in Higher Education during COVID-19—A Case Study of Web-Based Learning in Finland

2023

COVID-19 rapidly and extensively changed the normal everyday practices of societies, and there is no going back to the past. Universities also had to adapt and re-establish their normal routines, from policies to practices. In this article, we explore university students’ experiences of web-based learning, their well-being, and engagement during the pandemic. As a theoretical framework, we use the concept of the university student engagement inventory (USEI), which includes behavioral, cognitive, and emotional dimensions. The data were collected during the COVID-19 pandemic from university students (N = 35) via an online survey and analyzed using a thematic content analysis. According to th…

Protective and Educational Effects of Physical Activity Practice on Mental Health in Young Age during COVID-19 Lockdown

2022

Background: The restrictions imposed by the COVID-19 pandemic have modified the lifestyle of young people, worsening their mental health. Although some countries were allowed to practice outdoor physical activity (PA) in cases of lockdown, the PA level in the general population decreased. The current study aims to assess the differences in fear of COVID-19, anxiety, neuroticism, and general self-efficacy between university students who practiced PA during the second wave of lockdown and those who did not practice any PA. Methods: The sample consisted of 276 university students (176 females, 63.8%; mean age: 22.13, SD: ±3.94) who answered an online questionnaire detecting life habits …

The urban design guidance for the unmanaged spaces under elevated expressways upon users’ preferences

2016

There are many bridges in the Iranian major cities. It is still proceeded for constructing new bridges in order to solve traffic problems. The spaces under bridges and the expectations of users are rarely important for city officials and designers. Hence, this research is looking for guidelines of designing the unmanaged spaces under city bridges considering the environmental preferences of users. The main goal of this research is to achieve urban design guideline for designing the unmanaged spaces under elevated expressways based on expectations of individuals. This research is based on theoretical studies in the field of urban design, under bridge spaces, unmanaged spaces as well as envir…

Alteration-Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)

2021

International audience; Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability. We present a study that combines laboratory experiments, geophysical data, and large-scale numerical modeling to better understand the influence of alteration on volcano stability, using La Soufrière de Guadeloupe (Eastern Caribbean) as a case study. Laboratory experiments on variably altered (advanced argillic alteration) blocks show that uniaxial compressive strength, Young's modulus, and cohesion decrease as a function of increasing alteration, but that …

PROGETTARE L’ADATTAMENTO. Resilienze di agricoltura urbana nel contesto europeo

2022

I crescenti fenomeni legati al cambiamento climatico spingono le città a sviluppare piani di resilienza che possano rispondere in termini di sostenibilità ambientale, sociale ed economica. Le strategie nature-based possono rappresentare una soluzione; tra queste l’agricoltura urbana può contribuire ad aumentare la resilienza dei tessuti urbani europei. Questa attività è stata più volte oggetto di interesse in periodi di crisi come impegno comunitario dai caratteri sociali, oltre che produttivi ed educativi. Attraverso un excursus storico e una successiva analisi di casi studio contemporanei, il paper fornisce strumenti progettuali per intervenire nel costruito con strategie che spaziano dal…
