Tutkimuksen tavoitteena oli selvitt raaka-aineena kytettvn paloa hidastavan laminaattipaperin markkinapotentiaali sek kysynt Euroopassa. Niden kehityst arvioitiin analysoimalla kysyntn vaikuttavia tekijit. Tutkimusmetodologiassa yhdistyivt useat lhestymistavat, pasiassa kytettiin kuvailevaa ja ennustavaa tutkimusotetta. Tutkimus perustui sek primaari ett sekundaaritietoon. Primaaritietoa hankittiin tuotteen kyttjilt, myyntiedustajilta sek haastattelemalla tuottajayrityksen henkilkuntaa. Sekundaaritietoa kerttiin mys, mutta tutkimuksen tavoitteisiin liittyvi lhteit ei ollut runsaasti saatavilla. Tst syyst primaaritiedolla oli tutkimuksessa hieman trkempi rooli kuin sekundaaritiedolla, mik on yleist teollisessa markkinatutkimuksessa. Tuotteen tulevaisuuden nkymt vaikuttavat melko hyvilt. Teoreettinen markkinapotentiaali on suuri verrattuna nykyiseen myyntimrn, myyntimrn kasvattaminen vaatii kuitenkin tiettyj toimenpiteit. Tulevaisuudessa huomiota tulisi kiinnitt tuotekuvaan, hinnoitteluun ja laadun kokonaisvaltaiseen maksimointiin. Tutkimuksessa havaittiin suuntauksia kysynnn kasvusta tulevien parin vuoden aikana. Mys teoreettinen markkinapotentiaali voisi kasvaa, koska paloa hidastavien laminaattien kysynt vaikuttaa kasvavan Euroopassa erityisesti rakennusalalla.

En este trabajo se expone e ilustra un modelo terico para entender las funciones de la identidad, as como los mecanismospsicosociales asociados a su construccin: Modelo Evolutivo y Funcional de la Identidad Mediada (MEBIM). La identidad, mediada narrativamente, cumple una funcin personal orientada a la direccin de la propia vida, as como una funcin sociocultural vinculada a la bsqueda de reconocimiento de los derechos de los grupos sociales a los que uno se siente apegado. Se ilustran los factores asociados a la construccin de la identidad personal (s mismos posibles, transiciones vitales, vnculo afectivo) y sociocultural (accin-transformacin e identificacin simblica) a partir de 12 historias de vida realizadas con mestizos e indgenasde la Universidad Intercultural de Chiapas (Mxico). Se sugiere que en contextos educativos formales, como la escuela o la Universidad, se deben propiciar narrativas personales y socioculturales con el objetivo de optimizar la identidad en un mundo a la vez globalizado y plural

In the paper machine, it is not a desired feature for the boundary layer flows in the fabric and the roll surfaces to travel into the closing nips, creating overpressure. In this thesis, the aerodynamic behavior of the grooved roll and smooth rolls is compared in order to understand the nip flow phenomena, which is the main reason why vacuum and grooved roll constructions are designed. A common method to remove the boundary layer flow from the closing nip is to use the vacuum roll construction. The downside of the use of vacuum rolls is high operational costs due to pressure losses in the vacuum roll shell. The deep grooved roll has the same goal, to create a pressure difference over the paper web and keep the paper attached to the roll or fabric surface in the drying pocket of the paper machine. A literature review revealed that the aerodynamic functionality of the grooved roll is not very well known. In this thesis, the aerodynamic functionality of the grooved roll in interaction with a permeable or impermeable wall is studied by varying the groove properties. Computational fluid dynamics simulations are utilized as the research tool. The simulations have been performed with commercial fluid dynamics software, ANSYS Fluent. Simulation results made with 3- and 2-dimensional fluid dynamics models are compared to laboratory scale measurements. The measurements have been made with a grooved roll simulator designed for the research. The variables in the comparison are the paper or fabric wrap angle, surface velocities, groove geometry and wall permeability. Present-day computational and modeling resources limit grooved roll fluid dynamics simulations in the paper machine scale. Based on the analysis of the aerodynamic functionality of the grooved roll, a grooved roll simulation tool is proposed. The smooth roll simulations show that the closing nip pressure does not depend on the length of boundary layer development. The surface velocity increase affects the pressure distribution in the closing and opening nips. The 3D grooved roll model reveals the aerodynamic functionality of the grooved roll. With the optimal groove size it is possible to avoid closing nip overpressure and keep the web attached to the fabric surface in the area of the wrap angle. The groove flow friction and minor losses play a different role when the wrap angle is changed. The proposed 2D grooved roll simulation tool is able to replicate the grooved aerodynamic behavior with reasonable accuracy. A small wrap angle predicts the pressure distribution correctly with the chosen approach for calculating the groove friction losses. With a large wrap angle, the groove friction loss shows too large pressure gradients, and the way of calculating the air flow friction losses in the groove has to be reconsidered. The aerodynamic functionality of the grooved roll is based on minor and viscous losses in the closing and opening nips as well as in the grooves. The proposed 2D grooved roll model is a simplification in order to reduce computational and modeling efforts. The simulation tool makes it possible to simulate complex paper machine constructions in the paper machine scale. In order to use the grooved roll as a replacement for the vacuum roll, the grooved roll properties have to be considered on the basis of the web handling application.

During the past century, an increasingly diverse world provided us with opportunities for intercultural communication; especially the growth of commerce at all levels from domestic to international has made the combination of the theories of intercultural communication and international business necessary. As one of the main beneficiaries in international business in recent years, companies in airline industries have developed their international market. For instance, Finnair has developed its Asian strategy which responds to the increasing market demand for flights from Europe to Asia in the new millennium. Therefore, the company manages marketing communication in a global environment and becomes a suitable case for studying the theories of intercultural communication in the context of international marketing. Finnair implemented a large number of international advertisements to promote its Asian routes, where Asia has been constructed as a number of exotic destinations. Meanwhile, the company itself as a provider of these destinations has also been constructed contrastively. Thus, this thesis aims at research how Finnair constructs Asia and the company itself in the new millennium, and how these constructions compare with the theories of intercultural communication. This research applied the theories of international marketing, intercultural communication and culture. In order to analyze the collected corpora as Finnairs international advertisements and its annual reports in the new millennium, the methods of content analysis and discourse analysis have been used in this research. As a result, Finnair has purposefully applied the essentialist approach to intercultural communication and constructed Asia as an exotic Other due to the companys market orientation. Meanwhile, Finnair has also constructed the company itself two identities based on the same approach: as an international airline provider between Europe and Asia, as well as a part of Finnish society. The combination of intercultural communication and international marketing theories, together with the combination of the methods of content analysis and discourse analysis ensure the originality of this paper.

The forthcoming media revolution of exchanging paper documents to digital media in construction engineering requires new tools to be developed. The basis of this bachelors thesis was to explore the preliminary possibilities of exporting imagery from a Building Information Modelling software to a mobile phone on a construction yard. This was done by producing a Web Service which uses the design softwares Application Programming Interface to interact with a structures model in order to produce the requested imagery. While mobile phones were found lacking as client devices, because of limited processing power and small displays, the implementation showed that the Tekla Structures API can be used to automatically produce various types of imagery. Web Services can be used to transfer this data to the client. Before further development the needs of the contractor, benefits for the building master and inspector and the full potential of the BIM-software need to be mapped out with surveys.

The construction material sector, as a capital intensive industry, is highly vulnerable to rapid fluctuations in the economic cycles. In Finland this was witnessed especially during the late 2000s, as in 2007 and 2008 the demand for several construction materials exceeded their supply and right after this, in 2009 the demand collapsed fast as a result of an international recession. These factors brought about the need to study the future trends of the market place of the commissioning company, Finnsementti Oy. As reliable short term market forecasts for the sector are difficult to compose, the study concentrates primarily in examining and identifying the trends that are likely to affect the Finnish cement industry, and as an extension, the concrete industry in a frame of 10 to 15 years. The studys scope comprehends also the examination of the domestic construction sector, as it represents the end user industry of both cement and concrete. These motives for the study produce the research problem, which is to conduct a trend analysis for cement based building in the Finnish market area in the 2020s. The theoretical frame for composing a trend analysis in the case of this study is twofold. This is due to the fact that both, the macro and micro environments of the examined industries are studied. The main methods used are the PESTE-model (macro) and Porters five forces model (micro). The study applies a qualitative approach and the data is gathered by interviewing a group of experts from the cement, concrete and construction industries. The result of the paper is an overall trend analysis for the Finnish cement based building sector, which is based on sub trend analyses concerning four identified sub-sectors of the Finnish construction industry. The results are a combination of findings from these sub-sectors and the analyzed data that deals with the studied sectors macro and micro environment. The conclusions provide an overall picture of the examined sectors potential future as a whole and by defined sub-sectors of the construction industry. The recognition of future trends in different areas of the construction industry can be applied as a means for an industry actors decision making and in estimating the types of construction that are likely to grow or decline. Finally, based on the analyzed data and conclusions, the commissioning company is provided with a brief SWOT analysis, that provides additional tools for decision making and planning processes regarding the future.

Microscopic visualization, especially in transparent micromodels, can provide valuable information to understand the transport phenomena at pore scale in different process occurring in porous materials (food, timber, soils, etc.). Micromodels studies focus mainly on the observation of multi-phase flow, which presents a greater proximity to reality. The aim of this study was to study the process of flexography and its application in the manufacture of polyester resin transparent micromodels and its application to carrots. Materials used to implement a flexo station for micromodels construction were thermoregulated water bath, exposure chamber to UV light, photosensitive substance (photopolymer), RTV silicone polyester resin, and glass plates. In this paper, data on size distribution of a particular kind of carrot we used, and a transparent micromodel with square cross-section as well as a Log-normal pore size distribution with pore radii ranging from 10 to 110 m (average of 22 m and micromodel size of 10 10 cm) were built. Finally, it stresses that it has successfully implemented the protocol processing 2D polyester resin transparent micromodels.

On February 29, 1912 The Ontario Paper Company Limited was incorporated under the leadership of Col. Robert R. McCormick. Four months later construction began in Thorold, Ontario as this location was best for the abundance of power and water and water transportation. The first machine was started at the mill on September 5, 1913. The mill was one of the most advanced of its era, using electricity instead of water power. The mill was also the first of its kind as it combined pulp and paper making instead of separating the two operations.

Lobjet de recherche de ce mmoire est la rsilience vue travers le prisme dune dmarche autobiographique dans un contexte de recherche-formation. Le concept de rsilience pouvant tre sur ou sous-estim par divers chercheurs, lauteure dmontre dans lanalyse de son rcit de vie, le fait dune rsilience ordinaire et tout fait relle en opposition une rsilience hors de lordinaire. Lauteure aborde la notion de rsilience partir de diffrentes perspectives. Toutefois, elle privilgie lapproche des neurosciences qui dmontre, par le biais de limagerie crbrale, le remaniement du cerveau lors dinteractions. Or, pour bien des auteurs dont Boris Cyrulnik et Allan N. Schore, la rsilience prend racine suite une exprience dattachement, la rsilience ne se construisant pas seule. Le parcours autobiographique de lauteure est bien imprgn du processus thrapeutique danalyse bionergtique dans lequel elle sest engage.

Des dinosaures sur papier : des notes sur le terrain comme on en trouve dans le Badlands de Robert Kroetsch passe en revue cette uvre postmoderne de 1975 portant sur une expdition palontologique fictive prs de la rivire Red Deer, en Alberta, conformment la rcente tendance exiger la vrification systmatique des donnes la base des rcits mtafictifs historiographiques dans la littrature canadienne-anglaise. Inspire de lexploration canonique qua effectue John Livingston-Lowes des plus grands pomes de Samuel Taylor Coleridge par le biais de la mine dor du Gutch Memorandum Book dans The Road to Xanadu, cette thse entreprend un nouveau type de recherche qui se dmarque des archives conventionnelles et de la tradition documentaire. Sappuyant sur des documents holographes non publis provenant de dpts darchives situs au Qubec, en Ontario et en Alberta et crits par des collecteurs, des gologues et des palontologues de la Commission gologique du Canada, ainsi que sur des notes sur le terrain , des notes de recherche et des journaux personnels crits par Robert Kroetsch pendant la rdaction de son roman Badlands, cet examen critique rvle les strates sous-jacentes indites dune uvre de fiction particulire. Dans pratiquement toute fouille palontologique, le retrait de ce qui enveloppe un spcimen rvle souvent des donnes supplmentaires qui peuvent, si elles sont soigneusement interprtes, offrir des indices essentiels sur les environnements palontologiques. Ainsi, un squelette de dinosaure est rarement retir dune carrire strile dans son intgralit. Il en va de mme pour toute recherche sur un processus littraire. Aucun texte ne sautosuffit. Comme Kroetsch sest efforc de produire son rcit sous forme dinterrogation sur la cration et la transmission des donnes historiques, particulirement grce des notes sur le terrain , une vaste tude de ce terrain comprenant des intertextes de lAntiquit, des sciences, de lHistoire, de lhistoire populaire, de rcits de voyages et de la littrature canadienne et internationale est ici mene. On y fait librement rfrence des priodes et des auteurs trs diversifis, allant de Thomas Jefferson et des tombelles Bruce Chatwin et sa peau de brontosaure . videmment, aucune entreprise interdisciplinaire du genre ne peut tre exhaustive. Ce projet se veut plutt une vitrine littraire runissant des curiosits autour dune uvre principale, soit le Badlands de Robert Kroetsch. Rduites leur plus simple expression, les notes sur le terrain constituent des messages destins la postrit. En explorant trois thmes principaux, cette thse explique comment ces messages pourraient tre transmis. Saxa Loquuntur ! , ainsi intitul en rfrence lanalogie de Freud avec larchologie, traite des mtaphores associes aux tmoignages de la pierre ; Good Jones porte sur les faons dont la taxinomie peut combler le dsir dun chercheur dos de ne pas tomber dans loubli ; Box 16 suit une piste documentaire en parcourant les crits de Kroetsch pour reconstituer tant llaboration dun roman que les notions de temps, despace et dorigine dune uvre littraire.
