Technological and behavioral aspects of perforated building envelope in the Mediterranean region

2015

Perforated building envelope presents a global contemporary architectural trend which is connected – in some circumstances – to the traditional perforated models, such as ‘Mashrabiyya’, ‘Takhtabush’, ‘Qmariyyah’, etc. This study focuses on perforated models that have archetypical perforated elements within buildings and have technological and behavioural functions reflecting socio-cultural values, economic situation, and environmental needs of the building’s users. An analytical comparison (technologically and behaviourally) has been conducted between the selected contemporary cases of perforated buildings and the traditional models, by considering various aspects of the building’s envelope…

Aroma compound transfer between a solid food matrix and packaging films: a comprehensive approach

2008

International audience; Food quality is highly dependent on mass transfers occurring in food / packaging systems during storage. Particularly, aroma compound transfers are influenced by the composition and structure of the packaging and food matrix, the physico-chemical properties of aroma compounds and the conditions of the external environment (1). The influence of the food matrix on aroma compound-packaging film interactions was little studied in the literature (2,3). The objective of this work, in the framework of the French project CANAL ARLE, is to better understand aroma compound transfer into and through cellulosic and thermoplastic packaging films by taking into account their inter…

Understanding physiological and physicochemical influences on in-mouth aroma release from yogurts using mechanistic modelling

2008

International audience; On the basis of a first mechanistic model predicting aroma release in the oropharynx during food consumption, the aim of the present work was to improve its accuracy and to use it to identify the main mechanisms responsible for in-mouth aroma release. Comparison between predicted release kinetics and the ones measured by APCI-MS in the nasal cavity of subjects eating flavoured yogurt highlighted the reasonably accurate time predictions of the relative aroma concentration in the nasal cavity and the model ability to simulate successive swallowing events as well as partial velopharyngeal closure. Parameters identified as the most influent for in-vivo aroma release were…

Solid state conformational behavior and interactions of a series of aromatic oligoamide foldamers

2016

The topic of this thesis is aromatic oligoamide foldamers. The literary review of the thesis discusses the general features of foldamers and their design and then focuses on the specific examples of aromatic oligoamide foldamers. The experimental part of the thesis discusses the design and preparation of a family of aromatic oligoamide foldamers that can adopt a helical conformation. The folding is directed by intramolecular hydrogen bonding and stabilized by intramolecular aromatic interactions. The focus of the thesis is the analysis of the solid state conformations of ten foldamer analogues. The analysis is based on forty different crystal structures which are determined using single cry…

Performing arts and mediation technology in the period of lockdown

2021

Advancements in digital technologies have become novel ways to enrich communication, expression, and transmission of arts knowledge. Technology is increasingly implemented in the performance space, as a source of inspiration for artists. Especially in this period of lockdown, mediation technology has turned out to be an essential tool for different aspects of social life, as in performing arts. With venues, schools and artistic activities closed, performers, students and spectators have been obliged to keep connecting in remote conditions. This article wants to retrace the aesthetic impact of mediation technology in performing arts during this period of lockdown by focusing on the aspects t…

Non-structural proteins P17 and P33 are involved in the assembly of the internal membrane-containing virus PRD1.

2015

AbstractBacteriophage PRD1, which has been studied intensively at the structural and functional levels, still has some gene products with unknown functions and certain aspects of the PRD1 assembly process have remained unsolved. In this study, we demonstrate that the phage-encoded non-structural proteins P17 and P33, either individually or together, complement the defect in a temperature-sensitive GroES mutant of Escherichia coli for host growth and PRD1 propagation. Confocal microscopy of fluorescent fusion proteins revealed co-localisation between P33 and P17 as well as between P33 and the host chaperonin GroEL. A fluorescence recovery after photobleaching assay demonstrated that the diff…

“Can do!” Teacher Promotion of Optimism in Response to Student Failure Expectation Expressions in Classroom Discourse

2019

This study offers detailed observational analyses of how teachers use optimism as an instructional resource when responding to students’ failure expectation displays in classroom situations. The results were based on video-recordings of 25 lessons in two Finnish part-time special education settings, analysed by means of applied conversation analysis. The results showed that the teachers boosted optimism by inverting students’ negative utterances, giving examples of successful experiences of peers, offering praise for students’ earlier performance or focusing on problems through instructional support. The study underlines the importance of addressing and elaborating students’ negative learni…

Dust environment of an airless object: A phase space study with kinetic models

2016

Abstract The study of dust above the lunar surface is important for both science and technology. Dust particles are electrically charged due to impact of the solar radiation and the solar wind plasma and, therefore, they affect the plasma above the lunar surface. Dust is also a health hazard for crewed missions because micron and sub-micron sized dust particles can be toxic and harmful to the human body. Dust also causes malfunctions in mechanical devices and is therefore a risk for spacecraft and instruments on the lunar surface. Properties of dust particles above the lunar surface are not fully known. However, it can be stated that their large surface area to volume ratio due to their irr…
