Pasvik Water Quality until 2013 ; Environmental Monitoring Programme in the Norwegian, Finnish and Russian Border Area

The Pasvik monitoring programme was created in 2006 as a result of the trilateral cooperation and with the intention of following changes in the environment under variable pollution levels. Water quality is one of the basic elements of the programme when assessing the effects of the emissions from the Pechenganikel mining end metallurgical industry (Kola GMK). In this report temporal trends of the water chemistry during 2000–2013 are examined on the basis of the data gathered from lake Inari, River Pasvik and directly connected lakes, Lake Kuetsjarvi and 25 small lakes in three areas: Pechenganikel (Russia), Jarfjord (Norway) and Vätsäri (Finland). The lower parts of the Pasvik watercourse are impacted by both atmospheric pollution and direct wastewater discharge from the Pechenganikel smelter and the settlement of Nikel. The upper section of the watercourse and the small lakes and streams which are not directly linked to the Pasvik Watercourse only receive atmospheric pollution. Lake Inari is free of direct emissions from the Pechenganikel and the water quality is excellent. In River Pasvik and the directly connected lakes copper, nickel, and sulphates are the main pollutants. The most polluted water body is the Kolosjoki River as well as the stream connecting the Lakes Salmijarvi and Kuetsjarvi. The concentration of metals and sulphates in the water notably increases downstream the river lower Lake Kuetsjarvi. In Lake Kuetsjarvi copper and nickel concentrations are clearly elevated and have changed insignificantly in the last years of the research period. In the small border area lakes recovery from acidification in Vätsäri and Jarfjord is evident. Nickel and copper oncentrations have fluctuated but remained on clearly elevated level in Jarfjord and Pechenga. Copper concentrations have been slightly rising in the recent years. In Pechenga area nickel concentrations during the last four monitoring years are decreasing in some places but the regional trend through whole time series is still positive.

Fluvio-morphological processes of meander bends - Combining conventional field measurements, close-range remote sensing and computational modelling

Meandering rivers have been perceived to evolve rather similarly around the world independently of the location or size of the river. Despite the many consistent processes and characteristics they have also been noted to show complex and unique sets of fluviomorphological processes in which local factors play important role. These complex interactions of flow and morphology affect notably the development of the river. Comprehensive and fundamental field, flume and theoretically based studies of fluviomorphological processes in meandering rivers have been carried out especially during the latter part of the 20th century. However, as these studies have been carried out with traditional field measurements techniques their spatial and temporal resolution is not competitive to the level achievable today. The hypothesis of this study is that, by exploiting e increased spatial and temporal resolution of the data, achieved by combining conventional field measurements with a range of modern technologies, will provide new insights to the spatial patterns of the flow-sediment interaction in meandering streams, which have perceived to show notable variation in space and time. This thesis shows how the modern technologies can be combined to derive very high spatial and temporal resolution data on fluvio-morphological processes over meander bends. The flow structure over the bends is recorded in situ using acoustic Doppler current profiler (ADCP) and the spatial and temporal resolution of the flow data is enhanced using 2D and 3D CFD over various meander bends. The CFD are also exploited to simulate sediment transport. Multi-temporal terrestrial laser scanning (TLS), mobile laser scanning (MLS) and echo sounding data are used to measure the flow-based changes and formations over meander bends and to build the computational models. The spatial patterns of erosion and deposition over meander bends are analysed relative to the measured and modelled flow field and sediment transport. The results are compared with the classic theories of the processes in meander bends. Mainly, the results of this study follow well the existing theories and results of previous studies. However, some new insights regarding to the spatial and temporal patterns of the flow-sediment interaction in a natural sand-bed meander bend are provided. The results of this study show the advantages of the rapid and detailed measurements techniques and the achieved spatial and temporal resolution provided by CFD, unachievable with field measurements. The thesis also discusses the limitations which remain in the measurement and modelling methods and in understanding of fluvial geomorphology of meander bends. Further, the hydro- and morphodynamic models’ sensitivity to user-defined parameters is tested, and the modelling results are assessed against detailed field measurement. The study is implemented in the meandering sub-Arctic Pulmanki River in Finland. The river is unregulated and sand-bed and major morphological changes occur annually on the meander point bars, which are inundated only during the snow-melt-induced spring floods. The outcome of this study applies to sandbed meandering rivers in regions where normally one significant flood event occurs annually, such as Arctic areas with snow-melt induced spring floods, and where the point bars of the meander bends are inundated only during the flood events.

Remote sensing for three-dimensional modelling of hydromorphology

Successful management of rivers requires an understanding of the fluvial processes that govern them. This, in turn cannot be achieved without a means of quantifying their geomorphology and hydrology and the spatio-temporal interactions between them, that is, their hydromorphology. For a long time, it has been laborious and time-consuming to measure river topography, especially in the submerged part of the channel. The measurement of the flow field has been challenging as well, and hence, such measurements have long been sparse in natural environments. Technological advancements in the field of remote sensing in the recent years have opened up new possibilities for capturing synoptic information on river environments. This thesis presents new developments in fluvial remote sensing of both topography and water flow. A set of close-range remote sensing methods is employed to eventually construct a high-resolution unified empirical hydromorphological model, that is, river channel and floodplain topography and three-dimensional areal flow field. Empirical as well as hydraulic theory-based optical remote sensing methods are tested and evaluated using normal colour aerial photographs and sonar calibration and reference measurements on a rocky-bed sub-Arctic river. The empirical optical bathymetry model is developed further by the introduction of a deep-water radiance parameter estimation algorithm that extends the field of application of the model to shallow streams. The effect of this parameter on the model is also assessed in a study of a sandy-bed sub-Arctic river using close-range high-resolution aerial photography, presenting one of the first examples of fluvial bathymetry modelling from unmanned aerial vehicles (UAV). Further close-range remote sensing methods are added to complete the topography integrating the river bed with the floodplain to create a seamless high-resolution topography. Boat- cart- and backpack-based mobile laser scanning (MLS) are used to measure the topography of the dry part of the channel at a high resolution and accuracy. Multitemporal MLS is evaluated along with UAV-based photogrammetry against terrestrial laser scanning reference data and merged with UAV-based bathymetry to create a two-year series of seamless digital terrain models. These allow the evaluation of the methodology for conducting high-resolution change analysis of the entire channel. The remote sensing based model of hydromorphology is completed by a new methodology for mapping the flow field in 3D. An acoustic Doppler current profiler (ADCP) is deployed on a remote-controlled boat with a survey-grade global navigation satellite system (GNSS) receiver, allowing the positioning of the areally sampled 3D flow vectors in 3D space as a point cloud and its interpolation into a 3D matrix allows a quantitative volumetric flow analysis. Multitemporal areal 3D flow field data show the evolution of the flow field during a snow-melt flood event. The combination of the underwater and dry topography with the flow field yields a compete model of river hydromorphology at the reach scale.

Karboksyylihappojen kromatografinen fraktiointi

Suurin osa alifaattisista karboksyylihapoista tuotetaan nykyään synteettisesti, mutta öljyn hinnan nousu ja ekologisempi ajattelutapa on aiheuttanut kiinnostusta tuottaa näitä karboksyyli- ja hydroksihappoja jatkossa fermentoimalla tai sellun valmistuksen sivuvirtana syntyvästä mustalipeästä. Nykyään mustalipeä poltetaan sellaisenaan soodakattiloissa keittokemikaalien regeneroimiseksi, energiaksi ja sähköksi. Jatkossa mustalipeästä voisi erottaa arvokkaat orgaaniset hapot ennen polttamista. Saadusta happoseoksesta tulisi erottaa yksittäiset alifaattiset karboksyylihapot toisistaan jatkojalostusta varten. Tämän kandidaatintyön tavoitteena oli selvittää, millä kromatografisella erotusmenetelmällä fermentointituotteina ja teollisuuden sivuvirtoina syntyvistä karboksyylihapposeoksista saadaan yksittäiset alifaattiset karboksyylihapot erotettua toisistaan. Mittaukset suoritettiin kolonnilla, jossa hartsipedin halkaisija oli 1,5 cm ja korkeus 15 cm. Kolonnin erototusmateriaaleina kokeiltiin vahvoja ja heikkoja kationinvaihtohartseja, vahvaa anioninvaihtohartsia ja polymeerisiä adsorbentteja. Erotettavaksi happoseokseksi valittiin sitruuna-, viini-, glykoli-, maito- ja etikkahapon seos. Tehokkain erotus saatiin Puroliten valmistamalla Macronet 270:lla, joka on mikrohuokoinen polymeerinen adsorbentti. Macronet 270:lla saatiin erotettua erityisesti viini- ja glykolihappo sitruuna-, maito- ja etikkahaposta. Yksittäisiä happoja ei saatu kuitenkaan kunnolla erotettua. Parhaat koeolosuhteet erotustehokkuuden ja retentioaikojen kannalta saatiin vesieluentin virtausnopeudella 2 mL/min, syöttöpulssin tilavuudella 5 mL ja kolonnin lämpötilassa 75 °C.

Semi-automatic measurement of visual verticality perception in humans reveals a new category of visual field dependency

Previous assessment of verticality by means of rod and rod and frame tests indicated that human subjects can be more (field dependent) or less (field independent) influenced by a frame placed around a tilted rod. In the present study we propose a new approach to these tests. The judgment of visual verticality (rod test) was evaluated in 50 young subjects (28 males, ranging in age from 20 to 27 years) by randomly projecting a luminous rod tilted between -18 and +18° (negative values indicating left tilts) onto a tangent screen. In the rod and frame test the rod was displayed within a luminous fixed frame tilted at +18 or -18°. Subjects were instructed to verbally indicate the rod’s inclination direction (forced choice). Visual dependency was estimated by means of a Visual Index calculated from rod and rod and frame test values. Based on this index, volunteers were classified as field dependent, intermediate and field independent. A fourth category was created within the field-independent subjects for whom the amount of correct guesses in the rod and frame test exceeded that of the rod test, thus indicating improved performance when a surrounding frame was present. In conclusion, the combined use of subjective visual vertical and the rod and frame test provides a specific and reliable form of evaluation of verticality in healthy subjects and might be of use to probe changes in brain function after central or peripheral lesions.

2014 Ukraine crisis – Implications for corporate crisis management

In the late year 2013 events started to unfold in Ukraine’s capital city Kiev that would change the political and economic environment of the EU and Russia. The tension had been building for years between the two parties with Ukraine in the middle and during 2014 the tension blew up and events started to escalate into a crisis, which we now know as the 2014 Ukraine crisis. The crisis would include political, economic, and even military actions by all the parties involved with Ukraine slipping close to civil war. Both political and economic hardships followed for others as well with both the EU and Russia placing heavy political and economic sanctions on each other. Most notably in terms of this paper, the Russian federation placed total import embargo sanctions on food imports from the EU and some other countries. This meant that a Finnish dairy company, Valio, had to engage in corporate crisis management as almost a fifth of its total revenue was cut in a heartbeat. Valio had been prepared for some kind of complications with their Russian market as events started to unfold in Ukraine in the beginning of 2014 but never did they suspect that a complete shutdown of the Russian market would follow. The company is still recovering after more than a year after the sanctions were posed and have not been able to supplement the lost revenue streams. This research is a qualitative research aiming to find answers to the main questions: 1) What is the 2014 Ukraine crisis and what kind of special implications does it have and 2) How did the crisis affect Valio and how did Valio fare in its crisis management efforts. The data has been collected both from secondary document sources and primary sources. The main findings of this research are that the political and economic environment of the EU and Russia has gone through a profound change during the years 2013-2015. The companies and governments should re-evaluate what kind of environment they are now facing and what kinds of risks the new situation poses. This also calls for a deep academic analysis from the academic community. In corporate crisis management of Valio the main findings are that the former literature has looked into crisis management as one-time occurrence but the new crises and global events would call for a more on-going crisis analysis and active crisis management. Thus, corporate crisis management should be viewed as a cycle. Valio specifically handled the situation surprisingly well, considering that their revenue was indeed cut by a fifth. The main aspects of crisis management, which Valio did not handle as well, concern the learning curve of crisis management. They could be doing more in order to prepare for future crises better by learning from this experience. The situation is then still on-going in the autumn 2015 both in Ukraine and within Valio.

Co-operative acquisitions – the contextual factors and challenges for co-operatives when acquiring an investorowned firm

Mergers and acquisitions (M&As) have been seen as an important strategy in helping organizations to grow, gain access to new markets and resources, increase efficiency, and enable competitiveness in order to fulfil the purpose of the organization. These aspects have made M&As of central interest to academic literature. In co-operative studies mergers especially have been widely studied. The common focus of these studies is that M&As have taken place between organizations of the same form. It is noteworthy that there is a scarcity of literature concerning acquisitions between different organizational types. Moreover, M&As have not been evaluated concerning the organization’s ownership and purpose, which may be significant integration factors. The overall objective of this study is to describe and understand why co-operative organizations use acquisition as a strategic alternative. In more detail – and in order to develop understanding of the background ideals affecting the acquisition decision and the differences of organization ideals in the integration process – this study is based on a qualitative case study approach. By combining interview data gathered from the OPPohjola Group and associating the observations from various streams of research on acquisitions and management with the purpose of co-operation, and examining these issues further, the thesis contributes to the elaboration of theory in the field of the strategic management of co-operatives. The dissertation consists of two parts. The first part introduces the research topic, methods and publications, as well as discussing the overall outcomes. The second part consists of four publications that address the research questions from different viewpoints. The analyses of this dissertation indicate that, from the strategic point of view, the acquisition of an investor-owned firm by a co-operative organization may create competitive advantage for the co-operative. On the other hand, there are differences in and following from the purpose of acquirer and the acquiree that may, in such case, pose several challenges to the integration process.

Jätevesien puhdistus jätevesialtaissa jäädyttämällä - Kartoitus potentiaalisista sovellutuksista Suomessa

Uusia jäteveden puhdistusprosesseja kartoitetaan Suomessakin esimerkiksi kiristyvien päästömääräyksien vuoksi sekä parempia kustannus- ja energiatehokkuuksia tavoiteltaessa. Jätevesien puhdistus on Suomessa jo nykyään hyvällä tasolla, mutta muun muassa raskasmetallien, torjunta-aineiden, hormonien ja lääkeaineiden pitoisuuksien kasvut jätevesissä asettavat haasteita nykyisin käytössä oleville jäteveden puhdistusmenetelmille, sillä niitä ei ole suunniteltu näiden aineiden talteenottoon ja suurin osa aineista jää veteen. Lisäksi jätevedet halutaan nähdä enemmänkin resurssina kuin jätteenä, josta voidaan ottaa talteen hyödyllisiä komponentteja, kuten suoloja. Alueilla, joissa vuorokauden keskilämpötila pysyttelee edes osan vuodesta pakkasella, veden luonnollista jäätymisprosessia voidaan käyttää hyväksi jäteveden puhdistuksessa. Tässä työssä selvitettiin kiteytymisen teorian ja aikaisempien tutkimusten avulla, millaisten jätevesien puhdistukseen jäädytyskiteytys sopii sekä pohdittiin menetelmän potentiaalisia sovelluskohteita Suomessa. Jäädytyskiteytyksen todettiin olevan turvallinen ja energiatehokas ratkaisu monien koostumukseltaan erilaisien jätevesien puhdistukseen. Menetelmällä voitaneen puhdistaa öljyisiä, orgaanisia ja/tai epäorgaanisia epäpuhtauksia tai raskasmetalleja sisältäviä sekä myrkyllisiä jätevesiä. Olosuhteet prosessille ovat parhaat Pohjois-Suomessa, jossa vuorokauden keskilämpötila pysyttelee nollan alapuolella noin seitsemän kuukautta vuodesta. Etelä-Suomessa vastaava luku on kolme. Menetelmän potentiaalisia sovelluskohteita ovat esimerkiksi kaivosteollisuuden ja kaatopaikkojen jätevedet, joiden puhdistukseen jäädytyskiteytys saattaisi soveltua erinomaisesti. Jäädyttämällä voitaisiin myös puhdistaa tekstiili- ja nahkateollisuuden jätevesiä, sillä niiden sisältämien väriaineiden erottaminen vedestä on perinteisillä jäteveden puhdistusmenetelmillä usein vaikeaa tai jopa mahdotonta. Suolojen kiteyttämiseen vaadittavia korkeampia suolapitoisuuksia todettiin löytyvän lähinnä membraaniprosessien, kuten käänteisosmoosin, rejektivesistä. Sopivimmat eutektiset olosuhteet kiteyttämiseen ovat natriumsulfaatilla, kaliumsulfaatilla ja natriumkarbonaatilla. Veden luonnollisen jäätymisprosessin hyödyntäminen jätevedenpuhdistuksessa on huomionarvoinen idea. Prosessin käyttöönottoa haittaavat esimerkiksi korkeat investointikustannukset, mutta ne tulevat todennäköisesti ajan myötä teknologian kehittyessä laskemaan. Lisäksi monet prosessiin liittyvät käytännön asiat ovat vielä tutkimuksen alla. On myös huomattava, että Suomessakaan lämpötila ei pysyttele koko vuotta pakkasella, joten jäädytyksen rinnalla on oltava jokin toinen prosessi, jolla jätevedet puhdistetaan lämpötilan ollessa nollan yläpuolella.

Building climate justice : an analysis of how the nexus between climate change and human rights shapes public policy agendas and alternatives

This thesis provides an analysis of how the nexus between climate change and human rights shapes public policy agendas and alternatives. It draws upon seminal work conducted by John Kingdon, whose landmark publication “Agendas, alternatives, and public policy” described how separate streams of problems, solutions, and politics converge to move an issue onto the public policy agenda toward potential government action. Building on Kingdon’s framework, this research explores how human rights contribute to surfacing the problem of climate change; developing alternative approaches to tackling climate change; and improving the political environment necessary for addressing climate change with sufficient ambition. The study reveals that climate change undermines the realization of human rights and that human rights can be effective tools in building climate resilience. This analysis was developed using a mixed methods approach and drawing upon substantial literature review, the researcher’s own participation in international climate policy design; elite interviews with thought leaders dealing with climate change and human rights; and regular inputs from focus groups comprised of practitioners drawn from the fields of climate change, development and human rights. This is a journal based thesis with a total of six articles submitted for evaluation, published in peer‐reviewed publications, over a five year period. Denna avhandling analyserar hur klimatfrågan och mänskliga rättigheter i samverkan formar den politiska agendan och det politiskt möjliga. Den bygger på banbrytande forskning av John Kingdon, vars publikation “Agendas, alternatives, and public policy” beskriver hur en fråga blir politiskt viktig och lyfts upp på den politiska agendan. Med utgångspunkt i Kingdons ramverk, utforskar avhandlingen hur mänskliga rättigheter bidrar till att blottlägga klimatfrågan som problem; utveckla alternativa metoder för att angripa och hantera klimatfrågan; samt skapa ett politiskt klimat nödvändigt för att på ett ambitiöst sätt kunna angripa klimatfrågan. Studien visar att klimatförändringar undergräver mänskliga rättigheterna men att arbete med mänskliga rättigheter kan vara ett effektivt verktyg för att stå emot och hantera effekterna av klimatförändringar. Analysen har genomförts med hjälp av en rad olika metoder vilka inkluderar litteraturstudier, författarens egna observationer under klimatförhandlingar; intervjuer med ledande tänkare inom klimatfrågan och mänskliga rättigheter; samt data insamlad genom fokusgrupper bestående av yrkesverksamma inom klimat, utveckling och mänskliga rättigheter. Avhandlingen är baserad på totalt sex artiklar som publicerats i fackgranskade tidskrifter under en femårsperiod.

Desenvolvimentismo e novo-desenvolvimentismo: raízes teóricas e precisões conceituais

This paper starts from the conceptualism of New Developmentalism which was proposed by its formulators and their criticism of the "old" developmentalism in order to compare both. It is elaborate in both theoretical and historical levels. In the former, it explores the theoretical streams that contributed to the formulation of economic policies that designated the Latin American developmentalism. In the latter, it focuses on the economic policy of the Brazilian import-substitution industrialization and advocates the impropriety of associating it to the irresponsibility in the management of the foreign exchange, fiscal and monetary policies, as the proposers of New Developmentalism assert. Finally, in a third stage, it resumes the propositions of the New Developmentalism and debates the pertinence of some of its policy propositions based upon theoretical considerations and the Brazilian experience which were mentioned in the previous stages.
