The materiality of the immaterial. Services sectors and CO2 emissions in Uruguay

This paper analyzes the carbon dioxide emissions of the services sectors subsystem of Uruguay in 2004. Services, with the exception of transport, are often considered intangible because of their low level of direct emissions. However, the provision of services requires inputs produced by other sectors, including several highly materialintensive sectors. Through input–output analysis we investigate the relationship between the services subsystem and the rest of the economy as regards carbon dioxide emissions. This approach allows us to study the importance of the set of services branches as a unit in the economic structure as well as to analyze in detail the relationship between the branches. The results depict that services’ direct emissions are the main component, as a consequence of transport-related sectors. However, the pollution that the services subsystem makes the rest of the economy produce is very significant, and it is almost all explained by non-transport-related sectors. This analysis is useful for determining the sectors in which mitigation policies are more effective, and whether they would be better tackled through technical improvements and better practices or through demand policies.

Sellutehtaan sekundäärilämmön käytön tehostaminen

Energia on olennainen osa nykyaikaisen sellutehtaan prosesseja, joissa kuluu suuria määriä lämpöä ja sähköä. Pyrittäessä entistä kustannustehokkaampaan liiketoimintaan nousee energiatehokkuus usein mielenkiinnon kohteeksi. Pitkälle viety sähkön ja lämmön yhteistuotanto yhdistettynä korkeaan biopolttoaineiden osuuteen energian tuotannossa luovat pohjan tälle pyrkimykselle. Sekundäärilämpöä syntyy prosessien sivutuotteena ja sen mahdollisimman suuri hyödyntäminen on yksi keino päästä kohti parempaa energiatehokkuutta. Joissain tapauksissa sillä voidaan korvata jopa primäärienergian käyttöä ja mahdollisesti pienentää ostopolttoaineiden tarvetta. Diplomityössä tutkitaan sellutehtaan sekundäärilämpöjärjestelmän toimintaa, ohjausta ja energiankulutusta. Sekundäärilämpöjärjestelmästä muodostetaan taseet talvitilanteessa ja samalla etsitään mahdollisia uusia talteenotettavia sekundäärilämpövirtoja tai vastaavasti käyttökohteita. Lisäksi päivitetään sekundäärilämpöjärjestelmän raportoinnin ja ohjauksen työkaluja nykytilannetta vastaavaksi. Työn aikana kiinnitetään myös huomiota järjestelmän toimintaan muutostilanteissa, joissa kaikkia vesijakeita ei välttämättä ole saatavilla prosessin tarvitsemia määriä.

Métodos para fabricação de microeletrodos visando a detecção em microambientes

Analysis at microenvironments, like single cells or in minute volumes (nL), is an area of great interest for analytical and biological sciences. Measurements at these experimental conditions demand analytical tools (microelectrodes) capable of monitoring with rapid response, good resolution and minimal perturbation of the system. The major drawbacks in producing these microscopic electrodes have been largely overcome, principally due to the development of new fabrication methods. In this review, these procedures are described with emphasis to those devoted to the construction of microelectrodes for application in microenvironments. Examples of our efforts to use these devices as effective electrochemical sensors are also addressed.

Probing the (empirical) quantum structure embedded in the periodic table with an effective Bohr model

The atomic shell structure can be observed by inspecting the experimental periodic properties of the Periodic Table. The (quantum) shell structure emerges from these properties and in this way quantum mechanics can be explicitly shown considering the (semi-)quantitative periodic properties. These periodic properties can be obtained with a simple effective Bohr model. An effective Bohr model with an effective quantum defect (u) was considered as a probe in order to show the quantum structure embedded in the Periodic Table. u(Z) shows a quasi-smoothed dependence of Z, i.e., u(Z) ≈ Z2/5 - 1.

Improving demand forecasting practices in the industrial context

Demand forecasting is one of the fundamental managerial tasks. Most companies do not know their future demands, so they have to make plans based on demand forecasts. The literature offers many methods and approaches for producing forecasts. When selecting the forecasting approach, companies need to estimate the benefits provided by particular methods, as well as the resources that applying the methods call for. Former literature points out that even though many forecasting methods are available, selecting a suitable approach and implementing and managing it is a complex cross-functional matter. However, research that focuses on the managerial side of forecasting is relatively rare. This thesis explores the managerial problems that are involved when demand forecasting methods are applied in a context where a company produces products for other manufacturing companies. Industrial companies have some characteristics that differ from consumer companies, e.g. typically a lower number of customers and closer relationships with customers than in consumer companies. The research questions of this thesis are: 1. What kind of challenges are there in organizing an adequate forecasting process in the industrial context? 2. What kind of tools of analysis can be utilized to support the improvement of the forecasting process? The main methodological approach in this study is design science, where the main objective is to develop tentative solutions to real-life problems. The research data has been collected from two organizations. Managerial problems in organizing demand forecasting can be found in four interlinked areas: 1. defining the operational environment for forecasting, 2. defining the forecasting methods, 3. defining the organizational responsibilities, and 4. defining the forecasting performance measurement process. In all these areas, examples of managerial problems are described, and approaches for mitigating these problems are outlined.

Dieselmoottorin esisuunnittelun kehittäminen simuloimalla

Diplomityö tehtiin Wärtsilä Finland Oy:n toimeksiannosta. Työ kohdistui yrityksen suunnittelemien keskinopeudella pyörivien nelitahti dieselmoottoreiden esisuunnittelun kehittämiseen. Esisuunnittelun osuus koko tuotesuunnittelussa on merkittävä, minkä vuoksi esisuunnitteluprosessin tehostaminen vaikuttaa koko tuotesuunnitteluprosessiin ja sen lopputuloksiin. Tällä hetkellä esisuunnitteluprosessi on jakautunut useaan eri vaiheeseen ja eri tiimeille, mikä aiheuttaa ongelmia esisuunnittelun läpiviemisessä. Työn tavoitteena oli tutkia nykyaikaisen kaupallisen simulointiohjelmiston soveltuvuutta kohdeyrityksessä esisuunnitteluprosessin eri vaiheiden yhdistämiseen. Työssä selvitettiin esisuunnittelun alussa käytettäviä suunnitteluparametreja, ja niiden hyödyntämistä suunniteltaessa simulointimallia kaupalliseen ohjelmistoon. Vaatimuksena oli, että ohjelmiston on toimittava parametreilla, jotka jo nyt ovat yrityksessä käytössä. Lisäksi simulointimallin antamat tulokset oli oltava hyödynnettävissä yksiselitteisesti yrityksen myöhemmissä tuotesuunnitteluvaiheissa. Myös mallin luomiseen tarvittavien parametrien määrä tuli pitää mahdollisimman pienenä. Esisuunnittelumallin toteuttamisessa tutkittiin kaupallisen AVL Excite Designer - ohjelmiston soveltuvuutta. Ohjelmisto ei soveltunut täysin tuottamaan halutun muotoisia tuloksia annetuilla parametreilla. Ohjelmiston muokkaaminen vaatimuksia vastaavaksi osoittautui työmäärältään suureksi. Yhtenä ratkaisuna olisi kaupallisen ohjelmiston käyttämisen sijaan suunnitella kyseiseen ongelmaan paremmin soveltuva oma ohjelmisto, jolloin toimivuus ja pitkän tähtäimen käyttövarmuus paranisi.

Quality management of outsourcing welded structure: case China

For any international companies who wish to enter the Chinese market, quality is base on the fundamental. The companies are coming to realize the importance of quality gradually, thus companies have been put the quality problems on the agenda. The competitiveness of companies comes from quality. Quality is the key to success, and it can decide that the companies can be accepted or eliminated by the market. Due to the obvious benefits, the demand of the method of how to achieve high quality of product keeps growing. During achieving the high quality process, the main troubles come from the impact between Eastern and Western culture. Chinese culture which is different with Western one have lasted as long as five thousand years. Such a culture deeply rooted in the hearts of Chinese people, and effected generation after generation of Chinese people's working style and ways of thinking. This thesis determines how to find a good fit point between Eastern and Western culture. Doing right thing by the right way. The nature of improving quality is improving management level in fact. "How to manage, who should be managed", the thesis explains the basic and best option to achieve those. It describes three-dimension-style management to monitoring the working process. This kind of management style can inspect production process from horizontal and vertical direction. In this management way, it defines effective evaluation system to every subcontractor, and makes the companies to achieve the ultimate goal - satisfy quality. Because of the importance of human factor, the thesis determines the range of training of the inspector and welder due to the current situation of China. The results show that in order to reach reliable training effective evaluation, not only the quality of the human but also the ultimate goal of product quality.

Fatigue analysis of brackets with and without scallop for bridge and other deck structure using effective notch stress.

Due to functional requirement of a structural detail brackets with and without scallop are frequently used in bridges, decks, ships and offshore structure. Scallops are designed to serve as passage way for fluids, to reduce weld length and plate distortions. Moreover, scallops are used to avoid intersection of two or more welds for the fact that there is the presence of inventible inherent initial crack except for full penetrated weld and the formation of multi-axial stress state at the weld intersection. Welding all around the scallop corner increase the possibility of brittle fracture even for the case the bracket is not loaded by primary load. Avoiding of scallop will establish an initial crack in the corner if bracket is welded by fillet welds. If the two weld run pass had crossed, this would have given a 3D residual stress situation. Therefore the presences and absence of scallop necessitates the 3D FEA fatigue resistance of both types of brackets using effective notch stress approach ( ). FEMAP 10.1 with NX NASTRAN was used for the 3D FEA. The first and main objective of this research was to investigate and compare the fatigue resistance of brackets with and without scallop. The secondary goal was the fatigue design of scallops in case they cannot be avoided for some reason. The fatigue resistance for both types of brackets was determined based on approach using 1 mm fictitiously rounded radius based on IIW recommendation. Identical geometrical, boundary and loading conditions were used for the determination and comparison of fatigue resistance of both types of brackets using linear 3D FEA. Moreover the size effect of bracket length was also studied using 2D SHELL element FEA. In the case of brackets with scallop the flange plate weld toe at the corner of the scallop was found to exhibit the highest and made the flange plate weld toe critical for fatigue failure. Whereas weld root and weld toe at the weld intersections were the highly stressed location for brackets without scallop. Thus weld toe for brackets with scallop, and weld root and weld toe for brackets without scallop were found to be the critical area for fatigue failure. Employing identical parameters on both types of brackets, brackets without scallop had the highest except for full penetrated weld. Furthermore the fatigue resistance of brackets without scallop was highly affected by the lack of weld penetration length and it was found out that decreased as the weld penetration was increased. Despite the fact that the very presence of scallop reduces the stiffness and also same time induce stress concentration, based on the 3D FEA it is worth concluding that using scallop provided better fatigue resistance when both types of brackets were fillet welded. However brackets without scallop had the highest fatigue resistance when full penetration weld was used. This thesis also showed that weld toe for brackets with scallop was the only highly stressed area unlike brackets without scallop in which both weld toe and weld root were the critical locations for fatigue failure when different types of boundary conditions were used. Weld throat thickness, plate thickness, scallop radius, lack of weld penetration length, boundary condition and weld quality affected the fatigue resistance of both types of brackets. And as a result, bracket design procedure, especially welding quality and post weld treatment techniques significantly affect the fatigue resistance of both type of brackets.

Past, present and future - assessing changes in aquatic environments using subfossil diatoms

The deterioration of surface waters is one of the most important issues in the environmental management of the European Union. Thus, the EU Water Framework Directive 2000/60/EC (WFD) requires “good ecological and chemical status” of surface waters by 2015 allowing only a slight departure from ecological reference conditions characterized by the biological communities typical for the conditions of minimal anthropogenic impact. The WFD requires the determination of ecological reference conditions and the present ecological status of surface waters. To meet this legislative demand, sedimentary diatom assemblages were used in these studies with various methods 1) to assess natural and human activity induced environmental changes, 2) to characterize background conditions 3) to evaluate the present ecological status and 4) to predict the future of the water bodies in the light of palaeolimnological data. As the WFD refers to all surface waters, both coastal and inland sites were included. Two long and two short sediment cores from the Archipelago Sea in the northern Baltic Sea were examined for their siliceous microfossils in order to assess (1) the Holocene palaeoenvironmental history and (2) the recent eutrophication of the area. The diatom record was divided into local diatom assemblage zones (LDAZ, long cores) and diatom assemblage zones (DAZ, short cores). Locally weighted weighted averaging regression and calibration (LWWA) was applied for the quantitative reconstruction of past TN concentrations (short cores). An age model for the long cores was constructed by using independent palaeomagnetic and AMS-14C methods. The short cores were dated using radiometric (210Pb, 226Ra and 137Cs) methods. The long cores date back to the early history of the Archipelago Sea, which was freshwater – no salinity increase referable to the brackish phase of the Yoldia Sea is recognized. The nutrient status of the lacustrine phase was slightly higher in the Archipelago Sea than in the Baltic Proper. Initial brackish-water influence is observed at 8 150 ±80 cal. BP (LDAZ4), but fully brackish conditions were established at 7 700 ±80 cal. BP (LDAZ5). The diatom assemblages indicate increasing salinity, warming climate and possible eutrophic conditions during the lacustrine to brackish-water transition. The decreasing abundance of Pseudosolenia calcar-avis (Schultze) Sundström and the increasing abundance of the ice-cover indicator species Pauliella taeniata (Grunow) Round and Basson indicate decreasing salinity and climatic cooling after ca. 5 000 cal. BP. Signs of eutrophication are visible in the most recent diatom assemblage zones of both short cores. Diatom-inferred total nitrogen (DI-TN) reconstructions partially fail to trace the actual measured total nitrogen concentrations especially from the late 1980s to the mid 1990s. This is most likely due to the dominating diatom species Pauliella taeniata, Thalassiosira levanderi Van Goor and Fragilariopsis cylindrus (Grunow) W. Krieger being more influenced by factors such as the length of the ice-season rather than nutrient concentrations. It is concluded that the diatom assemblages of the study sites are principally governed by climate fluctuations, with a slight influence of eutrophication visible in the most recent sediments. There are indications that global warming, with reduced ice cover, could impact the spring blooming diatom species composition in the Archipelago Sea. In addition, increased sediment accumulation in the early 90s coincides with the short ice-seasons suggesting that warming climate with decreasing ice-cover may increase sedimentation in the study area. The diverse diatom assemblages dominated by benthic species (54 %) in DAZ1 in the Käldö Fjärd core can be taken as background diatom assemblages for the Archipelago Sea. Since then turbidity has increased and the diatom assemblages have been dominated by planktonic diatoms from around the mid 1800s onwards. The reconstructed reference conditions for the total nitrogen concentrations fluctuate around 400 μg l-1. Altogether two short sediment cores and eight short cores for top-bottom analysis were retrieved from Lake Orijärvi and Lake Määrjärvi to assess the impact of the acid mine drainage (AMD) derived metals from the Orijärvi mine tailings on the diatom communities of the lakes. The Cu (Pb, Zn) mine of Orijärvi (1757 – 1956) was the first one in Finland where flotation techniques (1911 – 1955) were used to enrich ore and large quantities of tailings were produced. The AMD derived metal impact to the lakes was found to be among the heaviest thus far recorded in Finland. Concentrations of Cu, Pb and Zn in Lake Orijärvi sediments are two to three orders of magnitude higher than background values. The metal inputs have affected Lake Orijärvi and Lake Määrjärvi diatom communities at the community levels through shifts in dominant taxa (both lakes) and at the individual level through alteration in frustule morphology (Lake Orijärvi). At present, lake water still has elevated heavy metal levels, indicating that the impact from the tailings area continues to affect both lakes. Lake Orijärvi diatom assemblages are completely dominated by benthic species and are lacking planktonic diatoms. In Lake Määrjärvi the proportion of benthic and tychoplanktonic diatoms has increased and the planktonic taxa have decreased in abundance. Achnanthidium minutissimum Kützing and Brachysira vitrea (Grun.) R. Ross in Hartley were the most tolerant species to increased metal concentrations. Planktonic diatoms are more sensitive to metal contamination than benthic taxa, especially species in the genus Cyclotella (Kützing) Brébisson. The ecological reference conditions assessed in this study for Lake Orijärvi and Lake Määrjärvi comprise diverse planktonic and benthic communitites typical of circumneutral oligotrophic lakes, where the planktonic diatoms belonging to genera Cyclotella , Aulacoseira Thwaites, Tabellaria Ehrenberg and Asterionella Hassall dominate in relative abundances up to ca. 70%. The benthic communities are more diverse than the planktonic consisting of diatoms belonging to the genera Achnanthes Bory, Fragilaria Lyngbye and Navicula St. Vincent. This study clearly demonstrates that palaeolimnological methods, especially diatom analysis, provide a powerful tool for the EU Water Frame Work Directive for defining reference conditions, natural variability and current status of surface waters. The top/bottom approach is a very useful tool in larger-scale studies needed for management purposes. This “before and after” type of sediment sampling method can provide a very time and cost effective assessment of ecological reference conditions of surface waters.

IDEAS for Strategic Technology Management: Design of an electronically mediated scenario method

The age-old adage goes that nothing in this world lasts but change, and this generation has indeed seen changes that are unprecedented. Business managers do not have the luxury of going with the flow: they have to plan ahead, to think strategies that will meet the changing conditions, however stormy the weather seems to be. This demand raises the question of whether there is something a manager or planner can do to circumvent the eye of the storm in the future? Intuitively, one can either run on the risk of something happening without preparing, or one can try to prepare oneself. Preparing by planning for each eventuality and contingency would be impractical and prohibitively expensive, so one needs to develop foreknowledge, or foresight past the horizon of the present and the immediate future. The research mission in this study is to support strategic technology management by designing an effective and efficient scenario method to induce foresight to practicing managers. The design science framework guides this study in developing and evaluating the IDEAS method. The IDEAS method is an electronically mediated scenario method that is specifically designed to be an effective and accessible. The design is based on the state-of-the-art in scenario planning, and the product is a technology-based artifact to solve the foresight problem. This study demonstrates the utility, quality and efficacy of the artifact through a multi-method empirical evaluation study, first by experimental testing and secondly through two case studies. The construction of the artifact is rigorously documented as justification knowledge as well as the principles of form and function on the general level, and later through the description and evaluation of instantiations. This design contributes both to practice and foundation of the design. The IDEAS method contributes to the state-of-the-art in scenario planning by offering a light-weight and intuitive scenario method for resource constrained applications. Additionally, the study contributes to the foundations and methods of design by forging a clear design science framework which is followed rigorously. To summarize, the IDEAS method is offered for strategic technology management, with a confident belief that it will enable gaining foresight and aid the users to choose trajectories past the gales of creative destruction and off to a brighter future.

The Process of Greening Cycle as Method of Operative Environmental

The structural change of society from product-based business to service- and further to need-based business has caused the fact that work for environmental issues has spread from conventional factories and environmentally harmful production to concern services and offices as well. Almost every company has an office, so a relatively small environmental burden caused by an individual office grows remarkable already at the state level and globally even more. Motivation to work for environmental issues in an individual office could be challenging even without the fact that wasted environmental impacts bound also wasted costs. Besides cost savings, a concretely greener image of a company has its value in the B2Cas well as in the B2B-field. Consumers and clients are more and more conscious of environmental issues and demand concrete actions instead of speeches, good thoughts and meaningless certifications. Internal work for environmental issues at a strategy level is not sufficient, so operational environmental management is needed for changing old practices. This research is about the effects of operative environmental management on the greening process of an office-based business. The research is outlined to concern the operative work in the office including field sales. Target was to concretely lower the environmental impacts of Lyreco Finland and to find cost savings directly by changing the operative practices in the office and also indirectly by affecting the level of environmental knowledge of the personnel. During the greening process, the aim was also to create concrete arguments for marketing as well. The circle of greening process, which was especially created for this diploma work, was used as a method. The circle divides a year to themes and sections separated by factors of environmental impacts. Separation is based on Brett Wills’ thoughts of seven green wastes (Wills, Brett. The Green Intensions. 2009) and follows it uneasily. The circle aimed at ensuring evolutionary growth of knowledge instead of being revolutionary in the changing process. Committing personnel to the process from its start by asking ideas from them and giving them clear directions was an important part of the research of operative management. Because of working from distance, communication with personnel was operated by frequent training days and weekly greening notes via emails and intranet. Also availability for communication was an important task because of the telecommuting. Research results of this work show that operative environmental management in an officebased business today is mostly management of change. When the strategic environmental friendliness is taken into a concrete level, the most important individual factor is motivating the operating personnel. Research shows that evolutionary change is found being an efficient way to make a change. Also understanding one´s own impact on the environmental burden and on the whole greening process clearly motivates the personnel. Results show that in the operative realization of the greening process, clear directions of new working practices, being as concrete as possible, and committing personnel to follow them make the process more effective. The operative environmental management and the cycle of the greening process decrease the environmental burden and save costs. The concrete results could be used as believable arguments in marketing and therefore exploited in communication with interest groups. Commitment of the management is also one of the key factors of success in the greening process. In this research, changes in the business field by a company trade took the focus of the management away from the greening process and made the process more inefficient by decreasing the amount of training days. The circle of greening process will be used as a tool in the future, as well, and therefore it will help observe environmental impacts of a company and increase sustainable development. Commitment of management to the evolutionary environmental work helps the operating personnel lower environmental impacts, decrease costs and build a concretely greener image.

Liiketoimintamalli teollisuuden ylijäämälämmön hyödyntämisestä kaukolämpöverkoissa

Tässä työssä tarkastellaan teollisuuden ylijäämälämmön hyödyntämistä kaukolämpöverkoissa liiketoimintamallin näkökulmasta. Työn tilaaja on YIT Teollisuus Oy, joka haluaa osaltaan olla mukana ratkaisemassa ilmastonmuutoksesta ja hiilidioksidipäästöjen vähentämistarpeista aiheutuvia yhteiskunnan kehitystarpeita. Energiatehokkuuden parantaminen on yksi nopeimmista keinoista vähentää päästöjä. Teollisuuden energiatehokkuutta voidaan parantaa ottamalla talteen sähköntuotannossa ja tuotantoprosesseissa syntyvää ylijäämälämpöä. Aikaisempien tutkimusten perusteella tiedetään, että Suomessa syntyy vuosittain noin 4–6 TWh ylijäämälämpöä, joka voitaisiin hyödyntää jo olemassa olevien kaukolämpöverkkojen välityksellä rakennusten lämmittämiseen. Kuitenkin vuonna 2008 teollisuus myi ylijäämälämpöä kaukolämpöverkkoihin yhteensä vain 770 GWh, mikä vastaa noin 2,5 prosenttia kokonaiskaukolämmön tarpeesta. Tämän työn tuloksena syntyi liiketoimintamalli, joka esittelee ne palvelut, jotka YIT tuottaa asiakkailleen tilanteissa, joissa teollisuudessa syntyvää ylijäämälämpöä hyödynnetään kaukolämpöverkoissa. Jotta liiketoimintamalli toimisi käytännössä, on siitä oltava hyötyä kaikille osapuolille. Asiakkaan on siis voitava kattaa palvelusta ja sen rahoituksesta syntyvät kustannukset myydyn ylijäämälämmön tuotolla (teollisuuslaitos) tai säästyneistä energian hankintakustannuksista (kaukolämpöyhtiö). Eniten ylijäämälämmön käytöstä voivat hyötyä kaukolämpöyhtiöt, joiden tuotannosta korkeintaan pieni osa tulee yhteistuotannosta ja joilla uusiutuvien energialähteiden osuus on vähäinen. Lisäksi kaukolämpöverkon koon vuotuisena kulutuksena mitattuna on oltava riittävän suuri ja kaukolämmön hinnan suhteellisen korkea. Myös alueen ennustettu väestönkasvu ja uudet suunnitteilla olevat asuinalueet saattavat parantaa ylijäämälämmön hyödyntämisen houkuttelevuutta. YIT:n näkökulmasta ylijäämälämmön talteenottoprojektit ovat hyvä lisä sen nykyiseen palvelutarjontaan. Myös yhteiskunnallisella tasolla aihe on merkittävä. Vaikka nykytietämyksen mukaan energian käytön tehostaminen ja päästöttömän tuotannon lisääminen ovat molemmat yhtä merkittäviä keinoja ilmastotavoitteiden saavuttamisen kannalta, panostetaan Suomessa tällä hetkellä lähinnä tuotannon tukemiseen. Lähivuosien poliittiset ratkaisut vaikuttavatkin vahvasti siihen, kuinka paljon tulevaisuudessa ylijäämälämpöä hyödynnetään rakennusten lämmittämisessä.
