A New Experimental Pulp Digester Installation with Separate Steam Supply

Part I Literature Survey Up to now, few articles have been written on the subject of Experimental Pulp Digester Installations. In our searches we have been able to find information concerning only The Pulp and Paper Research Institute of Canada in Montreal, P.Q., Canada, The Chemical Pulp Experimental Department of the Central Laboratory in Finland, and a sulfite digester for research and instruction at the University of Washington at Seattle, Washington, U.S.A

Stress response function of a two-dimensional ordered packing of frictional beads

We study the stress profile of an ordered two-dimensional packing of beads in response to the application of a vertical overload localized at its top surface. Disorder is introduced through the Coulombic friction between the grains which gives some indeterminacy and allows the choice of one constrained random number per grain in the calculation of the contact forces. The so-called `multi-agent' technique we use, lets us deal with systems as large as $1000\times1000$ grains. We show that the average response profile has a double peaked structure. At large depth $z$, the position of these peaks grows with $cz$, while their widths scales like $\sqrt{Dz}$. $c$ and $D$ are analogous to `propagation' and `diffusion' coefficients. Their values depend on that of the friction coefficient $\mu$. At small $\mu$, we get $c_0-c \propto \mu$ and $D \propto \mu^\beta$, with $\beta \sim 2.5$, which means that the peaks get closer and wider as the disorder gets larger. This behavior is qualitatively what was predicted in a model where a stochastic relation between the stress components is assumed.Comment: 7 pages, 7 figures, accepted version to Europhys. Let

What’s Language Got to do with it? An Exploration into the Learning Environment of Quebec’s Classes d’Accueil

This article stems from an on-going qualitative study of the ‘environment’ of Montreal’s elementary level welcome classes for new immigrant students (classes d’accueil), including teachers’ language attitudes and actual language practices in the classroom. Since the official language of instruction in Quebec is French, the classe d’accueil provides a unique setting for exploring many issues: how teachers look upon the linguistic and cultural diversity of their learners; how teachers negotiate their way between potentially opposing tensions-- to integrate newly arrived children into Quebec, and, to reinforce Quebec’s distinct cultural and linguistic status. By drawing on socio-cultural theory of language learning, this study explores the manner in which teachers might foster an inclusive learning environment in the classe d’accueil. Cet article est le résultat d’une étude qualitative en cours à l’école primaire qui analyse l’environnement des classes d’accueil pour nouveaux immigrants à Montréal. Elle analyse également les attitudes linguistiques et les pratiques langagières des professeurs dans la salle de classe. Comme la langue officielle de l’éducation au Québec est le français, ces classes d’accueil offrent un environnement unique pour explorer beaucoup de questions : comment les professeurs perçoivent-ils la diversité culturelle et linguistique de leurs apprenants, comment négocient-ils les tensions opposées, c’est-à dire comment font-ils pour intégrer des enfants qui viennent d’arriver au Québec en même temps que renforcer la particularité linguistique et culturelle de la province. Tout en se basant sur la théorie socio culturelle de l’apprentissage des langues, cette étude explore les différentes façons offertes aux professeurs qui encouragent la mise en place d’un environnement d’apprentissage inclusif en classe d’accueil

Potential Sinks for Geologic Storage of CO2 Generated in the Carolinas

This document summarizes a scoping study of the current state of knowledge of carbon storage options for our geographic area. The focus is on one aspect of carbon capture and storage—identification of deep saline aquifers in which carbon dioxide (CO2 ) generated in the Carolinas might be stored. The study does not address other aspects of CO2 storage projects, such as capture and compression of the gas, well construction and development, or injection. Transport of CO2 is touched upon in this study but has not been fully addressed. The information contained in this document is primarily from review of published geologic literature and unpublished data. No field data collection has been completed as part of this study. Further work will be necessary to increase confidence in the suitability of the potential CO2 storage sites identified in this report. This study does not address the regulatory, environmental, or public policy issues associated with carbon storage, which are under development at this time.Duke Energy, Progress Energy, Santee Cooper Power, South Carolina Electric and Gas, Electric Power Research Institute (EPRI), Southern States Energy Board (SSEB)Bureau of Economic Geolog

La géographie linguistique de l’Acadiana

On reconnaît depuis fort longtemps en Louisiane une région culturelle française. Récemment cette aire de forme triangulaire fut désignée « Acadiana ». Loin d'être homogène, Acadiana est extrêmement diversifié. Se servant des données du recensement de 1970, on peut y distinguer quatre types de zones linguistiques françaises : (1) zones de retranchement, (2) zones de solide majorité francophone, (3) zones équilibrées et (4) zones à minorité francophone.A unique French cultural region has long been noted in Louisiana. In recent years this triangular shaped area has received the designation "Acadiana". Far from being homogeneous, Acadiana is extremely diverse. Using French mother tongue population data from the 1970 census one can identify four types of French linguistic zones within Acadiana: (1) exclusive French, (2) solid majority, (3) balanced and (4) minority
