Maritime transportation in the Gulf of Finland in 2007 and in 2015

The Gulf of Finland is said to be one of the densest operated sea areas in the world. It is a shallow and economically vulnerable sea area with dense passenger and cargo traffic of which petroleum transports have a share of over 50 %. The winter conditions add to the risks of maritime traffic in the Gulf of Finland. It is widely believed that the growth of maritime transportation will continue also in the future. The Gulf of Finland is surrounded by three very different national economies with, different maritime transportation structures. Finland is a country of high GDP/per capita with a diversified economic structure. The number of ports is large and the maritime transportation consists of many types of cargoes: raw materials, industrial products, consumer goods, coal and petroleum products, and the Russian transit traffic of e.g. new cars and consumer goods. Russia is a large country with huge growth potential; in recent years, the expansion of petroleum exports has lead to a strong economic growth, which is also apparent in the growth of maritime transports. Russia has been expanding its port activities in the Gulf of Finland and it is officially aiming to transport its own imports and exports through the Russian ports in the future; now they are being transported to great extend through the Finnish, Estonian and other Baltic ports. Russia has five ports in the Gulf of Finland. Estonia has also experienced fast economic growth, but the growth has been slowing down already during the past couples of years. The size of its economy is small compared to Russia, which means the transported tonnes cannot be very massive. However, relatively large amounts of the Russian petroleum exports have been transported through the Estonian ports. The future of the Russian transit traffic in Estonia looks nevertheless uncertain and it remains to be seen how it will develop and if Estonia is able to find replacing cargoes if the Russian transit traffic will come to an end in the Estonian ports. Estonia’s own import and export consists of forestry products, metals or other raw materials and consumer goods. Estonia has many ports on the shores of the Gulf of Finland, but the port of Tallinn dominates the cargo volumes. In 2007, 263 M tonnes of cargoes were transported in the maritime traffic in the Gulf of Finland, of which the share of petroleum products was 56 %. 23 % of the cargoes were loaded or unloaded in the Finnish ports, 60 % in the Russian ports and 17 % in the Estonian ports. The largest ports were Primorsk (74.2 M tonnes) St. Petersburg (59.5 M tonnes), Tallinn (35.9 M tonnes), Sköldvik (19.8 M tonnes), Vysotsk (16.5 M tonnes) and Helsinki (13.4 M) tonnes. Approximately 53 600 ship calls were made in the ports of the Gulf of Finland. The densest traffic was found in the ports of St. Petersburg (14 651 ship calls), Helsinki (11 727 ship calls) and Tallinn (10 614 ship calls) in 2007. The transportation scenarios are usually based on the assumption that the amount of transports follows the development of the economy, although also other factors influence the development of transportation, e.g. government policy, environmental aspects, and social and behavioural trends. The relationship between the development of transportation and the economy is usually analyzed in terms of the development of GDP and trade. When the GDP grows to a certain level, especially the international transports increase because countries of high GDP produce, consume and thus transport more. An effective transportation system is also a precondition for the economic development. In this study, the following factors were taken into consideration when formulating the future scenarios: maritime transportation in the Gulf of Finland 2007, economic development, development of key industries, development of infrastructure and environmental aspects in relation to maritime transportation. The basic starting points for the three alternative scenarios were: • the slow growth scenario: economic recession • the average growth scenario: economy will recover quickly from current instability • the strong growth scenario: the most optimistic views on development will realize According to the slow growth scenario, the total tonnes for the maritime transportation in the Gulf of Finland would be 322.4 M tonnes in 2015, which would mean a growth of 23 % compared to 2007. In the average growth scenario, the total tonnes were estimated to be 431.6 M tonnes – a growth of 64 %, and in the strong growth scenario 507.2 M tonnes – a growth of 93%. These tonnes were further divided into petroleum products and other cargoes by country, into export, import and domestic traffic by country, and between the ports. For petroleum products, the share of crude oil and oil products was estimated and the number of tanker calls in 2015 was calculated for each scenario. However, the future development of maritime transportation in the GoF is dependent on so many societal and economic variables that it is not realistic to predict one exact point estimate value for the cargo tonnes for a certain scenario. Plenty of uncertainty is related both to the degree in which the scenario will come true as well as to the cause-effect relations between the different variables. For these reasons, probability distributions for each scenario were formulated by an expert group. As a result, a range for the total tonnes of each scenario was formulated and they are as follows: the slow growth scenario: 280.8 – 363 M tonnes (expectation value 322.4 M tonnes)

Ajopuusta asiantuntijaksi – luottamushenkilöarvioinnin merkitys kunnan johtamisessa ja päätöksenteossa

Tässä johtaminen ja organisaatiot –oppialaan kuuluvassa väitöstutkimuksessa selvitetään luottamushenkilöarvioinnin merkitystä kunnan johtamisessa ja päätöksenteossa. Tutkimuksessa kuvataan luottamushenkilöiden tekemää kunnan talouden ja hallinnon arviointia ja sen merkitystä kunnan johtamisen ja päätöksenteon palautemekanismina. Empiirisen haastatteluaineiston avulla kuvataan eteläkarjalaisten tarkastuslautakuntien toimintaa ja niiden puheenjohtajina toimineiden henkilöiden kokemuksia tarkastuslautakuntien olemassaolon kahdella ensimmäisellä valtuustokaudella 1997–2000 ja 2001–2004. Tutkimus kohdistuu julkiselle sektorille, kuntien poliittis-hallinnolliseen päätöksentekoon. Tarkastuslautakuntien synnyn taustalla ymmärretään vaikuttavan yleisenä viitekehyksenä erityisesti New Public Managementin (NPM) eli uuden julkisjohtamisen ilmaisemat ajatukset mm. toimintojen tehokkuudesta, tuloksellisuudesta ja vaikuttavuudesta sekä arvioinnista osana päätöksentekoa. Tutkimuksessa hyödynnetään kehysteoriana uuden julkisjohtamisen doktriinia ja substanssiteoriana arviointiin ja arviointitutkimukseen liittyvää teoreettista tietovarantoa. Tutkimuksen ensisijainen empiirinen aineisto koostuu 16 tarkastuslautakunnan puheenjohtajan haastattelusta, jotka on analysoitu sisällönanalyysiä käyttäen. Tausta-aineistona on käytetty 112 tarkastuslautakuntien arviointikertomusta. Tutkimus on ensimmäinen väitöskirjatasoinen työ tältä aihealueelta. Työn keskeinen kontribuutio on tutkimuksessa esitettävä näkemys luottamushenkilöarvioinnista ja sen merkityksestä kunnan johtamisessa arviointitutkimuksen, uuden julkisjohtamisen ja tarkastuslautakunnista tähän mennessä tehtyjen tutkimusten sekä empiirisen haastattelututkimuksen pohjalta. Luottamushenkilöarvioinnin painopisteen nähdään siirtyneen tarkastuslautakunnan lainmukaisen tehtävänannon eli valtuuston asettamien taloudellisten ja toiminnallisten tavoitteiden toteutumisen arvioinnista kunnan toiminnan kehittämiseen, jolloin sillä on konkreettisemmin päätöksentekoa tukeva merkitys. Taaksepäin suuntautunutta arviointia ei koeta kovinkaan merkitykselliseksi, vaikka virheistä oppimisen näkökulmasta ja päätöksenteon palautemekanismina myös ex post –arviointi on tärkeää. Tutkimuksessa on sovellettu poikkitieteellistä lähestymistapaa organisaatiotutkimuksen ja uuden julkisjohtamisen, arviointitutkimuksen sekä kuntatutkimuksen näkökulmia yhteen sovittamalla. Tutkimuksessa esitetään väite, että tarkastuslautakuntia kahlitsee niiden voimakas yhteys ja perustuminen tilintarkastukseen. Tarkastuslautakuntien arviointi ei ole kehittynyt omaehtoisesti ja luottamushenkilöarvioinnin merkitys on vielä osin tunnistamatta eritoten johtamisen itsensä arvioinnin näkökulmasta.

Keski-Suomen vapaa-ajankalastuksen kehittämisohjelma 2013–2017

Keski-Suomen vapaa-ajankalastuksen kehittämisohjelman 2013–2017 päämääränä on nimetä keskeiset vapaa-ajankalastuksen kehittämistavoitteet valitulla aikajänteellä. Ohjelman on laatinut Keski-Suomen elinkeino-, liikenne- ja ympäristökeskus alueellisena kalatalousviranomaisena yhteistyössä alan muiden toimijoiden kanssa. Ohjelmalla ei ole oikeusvaikutuksia, vaan se ohjaa kalatalousviranomaisen toimintaa ja auttaa suuntaamaan rahoitusta. Tärkeitä kumppaneita ohjelman toteutuksessa ovat kalatalousalan järjestöt, kalastusalueet, osakaskunnat, tutkimuslaitokset ja itse vapaa-ajankalastajat. Monipuolisuus ja vastuullisuus ovat Keski-Suomen vapaa-ajankalastuksen avainsanat tulevaisuudessa. Monipuolisuus tarkoittaa sitä, että vapaa-ajankalastusta harjoitetaan erilaisissa ympäristöissä ja että kalastaja arvostaa saaliina myös tavanomaisia kaloja ja kalalajeja. Näin harrastuksen vesiluontoa kohtaan aiheuttamaa painetta voidaan tasata alueellisesti. Vastuullisuuteen kuuluu, että tunnistetaan kalastusharrastuksen vaikutukset kalakantoihin, kalayksilöihin ja luontoon ja että kalavaroja käytetään kestävästi. Keski-Suomen maakunnan vapaa-ajankalastuksen kehittämisen tavoitteet vuosille 2013–2017 ovat: • vapaa-ajankalastusmahdollisuuksien monipuolinen hyödyntäminen • vastuullisen vapaa-ajankalastuksen tukeminen • vapaa-ajankalastuksen sosio-ekonomisten hyötyjen esiin nostaminen. Tavoitteita pyritään edistämään 12 toimenpiteen avulla. Nämä ovat 1. vapaa-ajankalastuksen infrastruktuurin kehittäminen, 2. luvanmyynnin parantaminen, 3. erityiskohteiden lisääminen, 4. lisätään lähikalastuskohteita ja muita matalan kynnyksen kalapaikkoja, 5. ekologisesti kestävien säätelytoimien käyttöönotto, 6. saaliin valinta ja käsittely 7. kalastuskilpailujen kehittäminen vastuullisemmaksi, 8. vaelluskalojen elinkierron turvaaminen, 9. tiedottaminen, 10. alan tutkimuksen edistäminen, 11. yhteistyön lisääminen kuntien kanssa, 12. vapaa-ajankalastustoimijoiden keskinäisen tiedonkulun parantaminen.

„Und frei erklär' ich alle meine Knechte“ : Höflichkeit als Ausdruck sozialer Utopie in Schillers Drama Wilhelm Tell.

My dissertation is an interdisciplinary study of the relationship between the Swiss peasants and nobles in Friedrich Schiller’s play Wilhelm Tell (1804). Changes to this relationship are of particular interest. Communication in the play is examined via a micro-analysis based on Penelope Brown’s and Stephen C. Levinson’s theoretical framework Politeness: Some universals in language usage. (1978, 1987). Brown and Levinson distinguish between positivepoliteness and negative-politeness strategies and their distinction is useful for my argument, since they claim that the use of positive-politeness strategies reflects the speaker’s intention to minimize the distance between the interlocutors (Brown and Levinson 1987: 103). Negative-politeness strategies, by contrast, result in social distancing (Brown and Levinson 1987: 130). In accordance with Brown’s and Levinson’s theory, it can be argued that the distribution of positive-politeness and negative-politeness strategies reflects changes in the distance between the fictional interlocutors as representatives of their social classes in Wilhelm Tell. The analysis of the communication in the play highlights that existing conflicts within the social groups are resolved and replaced with solidarity (cf. ‘Claim ’common ground’ and ‘Claim in-group membership with H’) before the peasants and noblemen appear on stage simultaneously in III, 3. In the scene in question, Geßler forces Tell to shoot the apple off his son’s head. Although both nobles and peasants are present, they do not communicate with each other. Thus, communication between the social classes occurs for the first time in IV, 2. This scene is crucial with regard to the changes in the relationship between the social classes in the play. The younger generation, with Rudenz as a representative of the nobility and Melchthal as a representative of the peasants, break with the prevailing conventions and initiate a new type of cooperation based on mutual helping and equality in the right and the duty to protect the country from the violent oppressors representing Habsburg (cf. ‘Convey that S and H are cooperators’, ‘Claim reflexivity’ and ‘Claim reciprocity’). The linguistic analysis reveals the crucial role of the Swiss nobility in the development of the social utopia, as well as the non-contribution of Wilhelm Tell. In fact, Tell never communicates with the Swiss noblemen. The role of the nobility and the role of Wilhelm Tell are further investigated in a comparison between Schiller’s Wilhelm Tell and four of Schiller’s historical sources. These sources, which contain earlier, non-dramatic versions of the establishment of the Swiss Confederation, are the following: Kronica von der loblichen Eydtgnoschaft compiled by Petermann Etterlin (1507), Gemeiner loblicher Eydgnoschafft Stetten Landen vnd Völckeren Chronik wirdiger thaaten beschreybung (1548) written by Johann Stumpf, Chronicon Helveticum of Aegidius Tschudi (the publication of Iselin from 1734 and 1736) and Johannes von Müller’s Geschichten schweizerischer Eidgenossenschaft (1786). Thecomparison sheds light on the fact that both Tschudi and von Müller emphasize unity among the Swiss and cooperation in their attempt to defeat the enemy. However, Schiller has reinforced the role of the nobility in the cooperation. In addition, the comparison between Schiller’s play and the historical sources reveals profound differences with regard to the role of Wilhelm Tell. In all of Schiller’s sources, Tell is present at Rütli, whereas he is absent from Rütli in Schiller’s play. In the play in general, Tell is conspicuously separated from the other peasants. Explanations of my linguistic results, which correspond to the above mentioned differences between the roles of the figures in Wilhelm Tell and the depictions in Schiller’s sources, are found by comparing the path of Schiller’s Swiss towards an egalitarian perspective with the kind of social evolution depicted by the German philosopher Johann Benjamin Erhard in his essay Über das Recht des Volks zu einer Revolution (1795). Aiming at considering Schiller’s social utopia within the larger cultural framework of the German response to the French Revolution, the comparison suggests that both authors depict the need for social change in terms of a change in social hierarchies (Erhard 1970: 95-96, cf. Foi 2005: 225). Erhard’s essay thus helps explain the political intention of Schiller’s play to keep the ideals of the French Revolution as crucial aims but profoundly change the means towards freedom and equality. In his attempt to claim the political resistance of the nobles and peasants as just, however, Schiller sacrificed the figure of Wilhelm Tell. Guilty of the murder of Geßler, Tell was no longer suitable for the righteous revolution imagined by Schiller (cf. Bloch 2008: 215 and Schulz 2005: 228). This explains Tell’s absence in the Rütli scene, his isolation in the plot, as well as his non-contribution to the social utopia. Together, the linguistic analysis and contextualisation of Schiller’s play support my hypothesis that Wilhelm Tell describes a process of change in the relationship between peasants and nobles. The interdisciplinary approach to the topic proved to be fruitful for all areas of the research involved.

Estudo comparativo do acúmulo de massa seca e macronutrientes por plantas de Zea mays e Ipomoea hederifolia

Foram realizados dois experimentos em casa de vegetação com o objetivo de estudar o acúmulo e a distribuição de massa seca e macronutrientes em milho e Ipomoea hederifolia. Plantas das duas espécies foram cultivadas, separadamente, em vasos com substrato de areia e irrigação com solução nutritiva. Os tratamentos foram representados pelas épocas de amostragem, realizada a intervalos de 14 dias, iniciando 21 dias após a emergência (DAE). Uma planta de milho apresentou crescimento lento até 30 DAE, quando a alocação de massa seca foi maior em raízes e folhas (80%), e uma planta de I. hederifolia, até 50 DAE, quando a alocação de massa seca foi maior em ramos e folhas (79%). O acúmulo máximo de massa seca foi quase cinco vezes maior em milho (134 g por planta) comparado a I. hederifolia (29 g por planta). Em média, os teores de N e K foram maiores em plantas de I. hederifolia. Os acúmulos máximos de macronutrientes pelo milho foram de 1.431, 474, 1.832, 594, 340 e 143 mg por planta, e por I. hederifolia, de 727, 52, 810, 350, 148 e 65 mg por planta, para N, P, K, Ca, Mg e S, respectivamente. A taxa de acúmulo médio diário de massa seca e macronutrientes pelas plantas de milho foi crescente até 87 DAE, atingindo o máximo aos 103 DAE, enquanto para as plantas de I. hederifolia foi crescente até 121 DAE, atingindo o máximo aos 138 DAE. Assim, além da interferência na colheita, uma população de I. hederifolia também pode competir por nutrientes com a cultura do milho.

Modulation of Signaling Molecules by Human Leucocyte Antigen B27; Special Reference to STAT1

Reactive arthritis (ReA) is an inflammatory joint disease, which belongs to the group of Spondyloarthritis (SpA). It may occur after infections with certain gram-negative bacteria such as Salmonella and Yersinia. SpAs are strongly associated with the human leucocyte antigen (HLA)-B27. Despite active research, the mechanism by which HLA-B27 causes disease susceptibility is still unknown. However, HLA-B27 has a tendency to misfold during assembly. It is possible that the misfolding of HLA-B27 could alter signaling pathways and/or molecules involved in inflammatory response in cells. We have earlier discovered that in HLA-B27-positive cells the interaction between the host and causative bacteria is disturbed. Our recent studies indicate that the expression of HLA-B27 may alter certain signaling molecules by disturbing their activation. The aim of this study was to investigate whether the expression of HLA-B27 disturbs the signaling molecules, especially the phosphorylation of transcription factor STAT1. STAT1 is an important mediator of inflammatory responses. Our results show that the phosphorylation of the STAT1 is significantly altered in HLA-B27-expressing U937 monocytic cells compared with control cells. STAT1 tyrosine 701 is more strongly phosphorylated in HLAB27- expressing cells; whereas the phosphorylation of STAT1 serine 727 is prolonged. Phosphorylation of STAT1 was discovered to be dependent on protein kinase PKR. Furthermore, we found out that the expression of posttranscriptional gene regulator HuR was altered in HLA-B27-expressing cells. We also detected that HLA-B27-positive cells secrete more interleukin 6, which is an important mediator of inflammation. These results help to understand how HLA-B27 may confer susceptibility to SpAs.

Radio-frequency-based measurement methods for bearing current analysis in induction motors

The most common reason for a low-voltage induction motor breakdown is a bearing failure. Along with the increasing popularity of modern frequency converters, bearing failures have become the most important motor fault type. Conditions in which bearing currents are likely to occur are generated as a side effect of fast du/dt switching transients. Once present, different types of bearing currents can accelerate the mechanical wear of bearings by causing deformation of metal parts in the bearing and degradation of the lubricating oil properties.The bearing current phenomena are well known, and several bearing current measurement and mitigation methods have been proposed. Nevertheless, in order to develop more feasible methods to measure and mitigate bearing currents, better knowledge of the phenomena is required. When mechanical wear is caused by bearing currents, the resulting aging impact has to be monitored and dealt with. Moreover, because of the stepwise aging mechanism, periodically executed condition monitoring measurements have been found ineffective. Thus, there is a need for feasible bearing current measurement methods that can be applied in parallel with the normal operation of series production drive systems. In order to reach the objectives of feasibility and applicability, nonintrusive measurement methods are preferred. In this doctoral dissertation, the characteristics and conditions of bearings that are related to the occurrence of different kinds of bearing currents are studied. Further, the study introduces some nonintrusive radio-frequency-signal-based approaches to detect and measure parameters that are associated with the accelerated bearing wear caused by bearing currents.

Contents of folates in edible mushrooms commercialised in the city of Campinas, São Paulo, Brazil

In this study, folates were evaluated in the main species of mushroom cultivated in Brazil. The species analysed were Agaricus bisporus (button mushroom), Lentinula edodes (shiitake) and Pleorotus ostreatus (shimeji). The five main forms of folate found in foods were determined: tetrahydrofolic acid (THFA), 10-methyl folic acid (10MFA), 5-methyl tetrahydrofolic acid (5MTHFA), 10-formyl folic acid (10FFA) and 5-formy tetrahydrofolic acid (5FTHFA). The methodology employed used extraction with phosphate buffer, clean up with trichloroacetic acid and separation of the vitamins by high-performance liquid chromatography, with simultaneous ultraviolet and fluorescence detection. The results obtained for total folate were 551 to 1404 µg.100 g -1 for the button mushroom, 606 to 727 µg.100 g -1 for shiitake and 460 to 1325 µg.100 g-1 for shimeji. The data showed that mushrooms could be considered as sources of folates and that their contribution of these vitamins to the diet was meaningful.
