Susceptibility of leguminous green manure species to Rhizoctonia solani and Sclerotium rolfsii

We studied the susceptibility of species used as green manure in common bean fields to root rot (Rhizoctonia solani) and southern blight (Sclerotium rolfsii). Seeds of Crotalaria breviflora, Canavalia ensiformis, Cajanus cajan, Dolichos lablab, Stizolobium cinereum, S. aterrimum, and the bean cvs. "Pérola", "Valente" and "Carnaval" were sown in soil infested by either R. solani AG-4 or S. rolfsii in greenhouse. The emergence of D. lablab seedlings in soil infested by R. solani dropped to 62%. C. breviflora, C. ensiformis and cv. "Valente" presented the lowest root rot severity. The pathogen S. rolfsii drastically reduced seedling emergence in all species; no C. cajan and S. cinereum seedling emerged. All plant species presented high southern blight severity. We conclude that leguminous crops are not suitable as green manure for areas of bean cultivation with high R. solani and S. rolfsii populations.

Waste Stream Investigation from Perspective of Changing Waste Legislation at Green Sand Foundries

The update of the Finnish legislation concerning waste was unavoidable, to comply with the European Union (EU) requirements defined in the EU-Directive on Waste. The new waste law updates were enacted into the Finnish legislation on the 11.03.2011 and targeted for applicability by the 11.03.2012. This thesis investigates the implications of the new amendments to the waste legislation from the perspective of green sand foundries. The investigations are conducted by comparing two of Componenta’s green sand foundries and evaluating their waste streams. Additionally, the impacts of legislation amendments are critiqued on their environmental and economic aspects. The study’s comparison of waste fractions at the two foundries reveals that sand is dominant in absolute tonnage and costs. The increments of waste taxes forces foundries to focus on waste management, recycling and disposing. The new legislation’s promotion of material efficiency, also guides foundries towards the prevention of waste. A potential preventive measure is to regenerate waste sand resulting to cost savings on both raw-materials and waste management. However, the lack of absolute targets for waste prevention or recycling rates discourages the interests towards creating or adopting new technologies and methods for the waste handling.

ESTIMATION OF CORK PRODUCTION USINGAERIAL IMAGERY1

ABSTRACT Inventory and prediction of cork harvest over time and space is important to forest managers who must plan and organize harvest logistics (transport, storage, etc.). Common field inventory methods including the stem density, diameter and height structure are costly and generally point (plot) based. Furthermore, the irregular horizontal structure of cork oak stands makes it difficult, if not impossible, to interpolate between points. We propose a new method to estimate cork production using digital multispectral aerial imagery. We study the spectral response of individual trees in visible and near infrared spectra and then correlate that response with cork production prior to harvest. We use ground measurements of individual trees production to evaluate the model’s predictive capacity. We propose 14 candidate variables to predict cork production based on crown size in combination with different NDVI index derivates. We use Akaike Information Criteria to choose the best among them. The best model is composed of combinations of different NDVI derivates that include red, green, and blue channels. The proposed model is 15% more accurate than a model that includes only a crown projection without any spectral information.

Venäläistä rulettia – Nuorten perhesuunnittelun esteet ja tarpeet Pietarissa ja Riiassa

Latviassa ja Venäjällä heikko demografinen tilanne on lisännyt keskustelua seksuaali- ja kansalaisoikeuksista sekä valtion merkityksestä niiden toteuttamisessa. Väestöpolitiikassa näkyy yhteiskunnallinen tilanne sekä sen kyky ja mahdollisuudet huomioida nuorten perhesuunnitteluun liittyviä tarpeita. Huomion kohteena on myös palvelujärjestelmä ja siinä toteutuva yksilöllinen taso. Tutkin perhesuunnittelua kokonaisvaltaisesti, mikä ilmenee erilaisten polkuriippuvuuksien tarkasteluina. Mielenkiintoiseksi kohteen tekee entisten sosialististen valtioiden erityislaatuisen murroksen läpikäyminen. Perhesuunnittelu on osa seksuaali- ja ihmisoikeuksia. Siihen kuuluu seksuaaliterveydestä tiedottaminen ja ohjaus sekä siihen liittyvät toimenpiteet. Perhesuunnittelu sisältää niin sosiaaliset, kasvatukselliset kuin lääketieteellisetkin näkökulmat. Siihen liitetään myös moraalisia ja taloudellisia näkemyksiä, sekä politiikkaa ja henkilökohtaisuutta. Tutkimustehtäväni on nuorten perhesuunnittelun esteet ja tarpeet Riiassa ja Pietarissa. Sovellan metodologisena lähestymistapana sosiaalihistoriallista ja etnografista tutkimusotetta, jolloin perinteen vaikutusten, kulttuuristen rakenteiden ja yksilöllisten toimintatapojen ymmärtäminen mahdollistuu. Aineisto koostuu viranomaishaastatteluista sosialismin kaudella toteutuneesta sekä nykyisestä perhesuunnittelusta ja nuorten haastatteluista Pietarissa ja Riiassa. Perehdyn myös lisääntymisterveyteen liittyviin sanomalehtiartikkeleihin sekä Latviassa että Venäjällä. Lisäksi havainnoin seksuaalineuvontatilanteita Pietarissa. Sekä sosialismin aikana että nykyään painottuvat väestönkasvun odotukset, joita tuetaan sukupuoli- ja moraalikasvatuksen avulla. Perhesuunnittelun esteiden analyysin tuloksissa on nähtävissä sosiaalisten olosuhteiden ja rakenteiden merkitys. Jälkisosialistisesta riskiyhteiskunnasta puuttuvat yhteiskuntaan integroitumisen mahdollistavat instituutiot. Tämä ilmenee yhteiskunnallisena vastuuttomuutena. Universaalit palvelut ovat suurelta osin peräisin sosialismin ajalta. Kaupalliset yritykset tekevät lähinnä teknisiä, yksittäisiä ehkäisyvälineisiin liittyviä interventioita nuorten elämään. Teini-ikäiset jätetään oman harkintansa varaan. Latviassa perhesuunnitteluun liittyvä ennalta ehkäisevä toiminta on huomioitu uudessa lisääntymisterveyslaissa, mutta sen heikko toteutus tuo sen lähelle neuvostoaikaista kulttuurikonventiota, jossa määrällisillä suoritteilla ja sekundaaripreventiolla on arvoa. Venäjällä voimavarat kohdentuvat jälkihuollon palveluihin. Foucaultin valta-analyysi kertoo strategiasta, jossa ihminen sisäistää vallankäytön osaksi omaa ajatteluaan ja toimintaansa. Tässä näkökulmassa yksilöllinen, yhteiskunnallinen ja historiallinen ulottuvuus limittyvät toisiinsa. Vallan muodot ovat yhteiskunnan rakenteissa. Väestöpolitiikan avulla tuotetaan tietoa ja muovataan hallitsemisen kohteita. Osa haastatelluista nuorista omaksui yhteiskunnan passiivisuuden osaksi omaa toimintaansa. He eivät tiedostaneet palvelujärjestelmän puutteita eivätkä kyseenalaistaneet sen oikeutusta. Myös lehtiartikkelit ja viranomaishaastattelut tukivat osittain seksuaalikasvatuksen sivuuttamista. Silloin hyväksyttävänä totuutena pidettiin väestöpolitiikkaa, jossa on annettu tilaa populistisille suuntauksille. Sekä Latviassa että Venäjällä ilmaistiin tavoitteita väestön kasvusta. Kansainvälisten seksuaalioikeuksien maihinnousu ei ole poistanut ääri uskonnollisten ja osittain kansalaisjärjestöjen puitteissa tapahtuvaa perhesuunnittelun vastustusta. Näissä suuntauksissa vaikutetaan ihmisten moraaliin ja vastustetaan yhteiskunnan interventioita kieltämällä seksuaalikasvatus. Sosialismin aikana sosiaali- ja terveydenhuoltoa toteutettiin totalitaristisessa, suljetussa yhteiskunnassa tiukasti rajatuilla voimavaroilla. Tuolta ajalta peräisin oleva viranomaisten yleinen medikalisoitunut ja tekninen lähestymistapa estää osittain nuoren valtaistumista. Vieläkin heikko tiedottaminen ja puutteellinen koulutus vaikuttavat ammattilaisten keskuudessa. Yksi haitallisista perhesuunnitteluun kuuluvista uskomuksista oli hormonaalisen ehkäisyn aiheuttamat ongelmat. Lisäksi pelättiin heikkotasoisesti tehtyjen aborttien aiheuttavan hedelmättömyyttä. Uskomukset ovat eläneet vieläkin, kun osa asiantuntijoista kannusti ensimmäisen raskauden päättymistä synnytykseen. Näillä käsityksillä on ollut taipumus siirtyä sukupolvelta toiselle myös kansalaisten keskuudessa. Sukuyhteisöjen ja verkostojen oleellinen merkitys teini-ikäisen arjessa ja selviytymisessä painotti perinteistä sosialisaatiota. Uskomusten lisäksi nuorten heikko taloudellinen tilanne on ohjannut heitä ehkäisyssä luonnonmenetelmien käyttöön. Neuvostoaikainen seksuaalikielteisyyden perinne on vaikuttanut myös sukupolvien kyvyttömyyteen keskustella aiheesta. Yleisen ennaltaehkäisevän neuvonnan puuttuminen on suunnannut suurta osaa nuoria mallioppimiseen, jossa esimerkit ovat nousseet satunnaisista löydöistä. Toisaalta työntekijöiden neuvokkuus ja aloitteellisuus erilaisissa ohjaamistilanteissa, toimintatavoissa ja instituutioiden perustamisissa kuvaavat eettistä vastuunottoa ja paneutumista nuorten perhesuunnittelun toteutumiseen sekä sen mahdollisuuksiin. Perhesuunnitteluun liittyvän tiedonsaannin parantamiseksi viranomaiset ovat aloittaneet nuorten vertaisryhmiä. Lisäksi yhtenä uutena virallisena lähestymistapana oli neuvostoaikana kielletty psykoterapeuttisen suuntauksen avoin käyttöönotto. Myös nuorille suunnattuja palveluja niin lainsäädännön kuin instituutioiden tasolla on saatu aikaan. Nämä myönteiset tapaukset jäivät kuitenkin yksittäisiksi, osittain joidenkin työntekijöiden omakohtaisen sitoutumisen varaan toimiviksi. Tutkimuksessa nousee esiin yhteiskunnan vastuu erityisesti haavoittuvien ryhmien kohdalla. Nuoret ovat tiedoiltaan ja kokemuksiltaan heikossa asemassa. Sosiaalipoliittisesta näkökulmasta julkisilla ja ennaltaehkäisevillä palveluilla on keskeinen merkitys etenkin niiden kohdalla, jotka tarvitsevat runsaasti palveluja. Usein tähän ryhmään kuuluvat ovat passiivisia tiedon hakijoita. Tutkimus tuo esille perhesuunnittelun palvelujärjestelmään ja sen kohderyhmään kuuluvan moniulotteisuuden, jossa toisiinsa nivoutuvat kulttuuriset myytit, uskomukset, tabut, toimintatavat ja tietämys. Näiden polkujen avaaminen tässä tutkimuksessa edistää perhesuunnittelun esteiden tunnistamista ja niihin soveltuvien ratkaisukeinojen löytymistä.

Military crisis management in the next decade (2020-2030) : inducing consent or relying on compliance?

The most outstanding conceptual challenge of modern crisis management is the principle of consent. It is not a problem only at the operational level - it challenges the entire decision-making structures of crisis management operations. In post-cold war times and especially in the 21st century, there has been a transition from peacekeeping with limited size and scope towards large and complex peace operations. This shift has presented peace operations with a dilemma. How to balance between maintaining consent for peace operations, whilst being able to use military force to coerce those attempting to wreck peace processes? To address such a dilemma, this research aims to promote understanding, on what can be achieved by military crisis management operations (peace support operations) in the next decade. The research concentrates on the focal research question: Should military components induce consent or rely on the compliance of conflicting parties in crisis management operations of the next decade (2020 – 2030)? The focus is on military – political strategic level considerations, and especially on the time before political decisions to commit to a crisis management operation. This study does not focus on which actor or organisation should intervene. The framework of this thesis derives from the so called ‘peacebuilding space’, the scope of peace operations and spoiler theory. Feasibility of both peace enforcement and peacekeeping in countering future risk conditions are analysed in this framework. This future-orientated qualitative research uses the Delphi-method with a panel of national and international experts. Citation analysis supports identification of relevant reference material, which consists of contemporary literature, the Delphi-questionnaires and interviews. The research process followed three main stages. In the first stage, plausible future scenarios and risk conditions were identified with the Delphi-panel. In the second stage, operating environments for peace support operations were described and consequent hypotheses formulated. In the third stage, these hypotheses were tested on the Delphi-panel. The Delphi-panel is sufficiently wide and diverse to produce plausible yet different insights. The research design utilised specifically military crisis management and peace operations theories. This produced various and relevant normative considerations. Therefore, one may argue that this research; which is based on accepted contemporary theory, hypotheses derived thereof and utilising an expert panel, contributes to the realm of peace support operations. This research finds that some degree of peace enforcement will be feasible and necessary in at least the following risk conditions: failed governance; potential spillover of ethnic, religious, ideological conflict; vulnerability of strategic chokepoints and infrastructures in ungoverned spaces; as well as in territorial and extra-territorial border disputes. In addition, some form of peace enforcement is probably necessary in risk conditions pertaining to: extremism of marginalised groups; potential disputes over previously uninhabited and resource-rich territories; and interstate rivalry. Furthermore, this research finds that peacekeeping measures will be feasible and necessary in at least risk conditions pertaining to: potential spillover of ethnic, religious, ideological conflict; uncontrolled migration; consequences from environmental catastrophes or changes; territorial and extra-territorial border disputes; and potential disputes over previously uninhabited and resource-rich territories. These findings are all subject to both generic and case specific preconditions that must exist for a peace support operation. Some deductions could be derived from the research findings. Although some risk conditions may appear illogical, understanding the underlying logic of a conflict is fundamental to understanding transition in crisis management. Practitioners of crisis management should possess cognizance of such transition. They must understand how transition should occur from threat to safety, from conflict to stability – and so forth. Understanding transition is imperative for managing the dynamic evolution of preconditions, which begins at the outset of a peace support operation. Furthermore, it is pertinent that spoilers are defined from a peace process point of view. If spoilers are defined otherwise, it changes the nature of an operation towards war, where the logic is breaking the will of an enemy - and surrender. In peace support operations, the logic is different: actions towards spoilers are intended to cause transition towards consent - not defeat. Notwithstanding future developments, history continues to provide strategic education. However, the distinction is that the risk conditions occur in novel futures. Hence, lessons learned from the past should be fitted to the case at hand. This research shows compelling evidence that swaying between intervention optimism and pessimism is not substantiated. Both peace enforcement and peacekeeping are sine qua non for successful military crisis management in the next decade.

Potential of utilization of rain water excess for irrigation of green roofs in Mato Grosso, Brasil

The aim of this study was to identify the relation between the evapotranspirometer demand and the supply of water from local rainfall, evaluating the possibility of using water excess for irrigation of Green Roofs in the State of Mato Grosso, in Brazil. The study was done using a series of historical data provided by the National Institute of Meteorology (INMET - Instituto Nacional de Meteorologia) which has official climatological stations in 12 cities and regions of the State. The evapotranspiration values were obtained by the Penman-Monteith method and by the Climatic Water Balance (CWB) by the Thornthwaite and Mather method using Available Water Capacity (AWC) of 12mm. With the CWB the excess and deficit were calculated, which were used for the estimative of the volume and area of a reservoir as a function of a collector area of a roof of 100m² and the volume of supplementary water for irrigation. With the obtained results, it was found that in most investigated regions of the State the use of green roofs is not compromised by the water deficiency. On the other hand, the use of a reservoir to accumulate the rain water excess may be impractical, because it requires a considerable area for installation and also because of the high cost of the land.

Design of Pulsed Electroacoustic Measurement System for Space Charge Characterisation

Pulsed electroacoustic (PEA) method is a commonly used non-destructive technique for investigating space charges. It has been developed since early 1980s. These days there is continuing interest for better understanding of the influence of space charge on the reliability of solid electrical insulation under high electric field. The PEA method is widely used for space charge profiling for its robust and relatively inexpensive features. The PEA technique relies on a voltage impulse used to temporarily disturb the space charge equilibrium in a dielectric. The acoustic wave is generated by charge movement in the sample and detected by means of a piezoelectric film. The spatial distribution of the space charge is contained within the detected signal. The principle of such a system is already well established, and several kinds of setups have been constructed for different measurement needs. This thesis presents the design of a PEA measurement system as a systems engineering project. The operating principle and some recent developments are summarised. The steps of electrical and mechanical design of the instrument are discussed. A common procedure for measuring space charges is explained and applied to verify the functionality of the system. The measurement system is provided as an additional basic research tool for the Corporate Research Centre of ABB (China) Ltd. It can be used to characterise flat samples with thickness of 0.2–0.5 mm under DC stress. The spatial resolution of the measurement is 20 μm.

Loss Modelling of Three-Level Inverters controlled with Space Vector Modulation Technique

The objective of this master’s thesis is to investigate the loss behavior of three-level ANPC inverter and compare it with conventional NPC inverter. The both inverters are controlled with mature space vector modulation strategy. In order to provide the comparison both accurate and detailed enough NPC and ANPC simulation models should be obtained. The similar control model of SVM is utilized for both NPC and ANPC inverter models. The principles of control algorithms, the structure and description of models are clarified. The power loss calculation model is based on practical calculation approaches with certain assumptions. The comparison between NPC and ANPC topologies is presented based on results obtained for each semiconductor device, their switching and conduction losses and efficiency of the inverters. Alternative switching states of ANPC topology allow distributing losses among the switches more evenly, than in NPC inverter. Obviously, the losses of a switching device depend on its position in the topology. Losses distribution among the components in ANPC topology allows reducing the stress on certain switches, thus losses are equally distributed among the semiconductors, however the efficiency of the inverters is the same. As a new contribution to earlier studies, the obtained models of SVM control, NPC and ANPC inverters have been built. Thus, this thesis can be used in further more complicated modelling of full-power converters for modern multi-megawatt wind energy conversion systems.

Quantum Tomography with Phase Space Measurements

This thesis addresses the use of covariant phase space observables in quantum tomography. Necessary and sufficient conditions for the informational completeness of covariant phase space observables are proved, and some state reconstruction formulae are derived. Different measurement schemes for measuring phase space observables are considered. Special emphasis is given to the quantum optical eight-port homodyne detection scheme and, in particular, on the effect of non-unit detector efficiencies on the measured observable. It is shown that the informational completeness of the observable does not depend on the efficiencies. As a related problem, the possibility of reconstructing the position and momentum distributions from the marginal statistics of a phase space observable is considered. It is shown that informational completeness for the phase space observable is neither necessary nor sufficient for this procedure. Two methods for determining the distributions from the marginal statistics are presented. Finally, two alternative methods for determining the state are considered. Some of their shortcomings when compared to the phase space method are discussed.

Key performance indicators for successful metadata governance

Metadata in increasing levels of sophistication has been the most powerful concept used in management of unstructured information ever since the first librarian used the Dewey decimal system for library classifications. It remains to be seen, however, what the best approach is to implementing metadata to manage huge volumes of unstructured information in a large organization. Also, once implemented, how is it possible to track whether it is adding value to the company, and whether the implementation has been successful? Existing literature on metadata seems to either focus too much on technical and quality aspects or describe issues with respect to adoption for general information management initiatives. This research therefore, strives to contribute to these gaps: to give a consolidated framework for striving to understand the value added by implementing metadata. The basic methodology used is that of case study, which incorporates aspects of design science, surveys, and interviews in order to provide a holistic approach to quantitative and qualitative analysis of the case. The research identifies the various approaches to implementing metadata, particularly studying the one followed by the unit of analysis of case study, a large company in the Oil and Gas Sector. Of the three approaches identified, the selected company already follows an approach that appears to be superior. The researcher further explores its shortcomings, and proposes a slightly modified approach that can handle them. The research categorically and thoroughly (in context) identifies the top effectiveness criteria, and corresponding key performance indicators(KPIs) that can be measured to understand the level of advancement of the metadata management initiative in the company. In an effort to contrast and have a basis of comparison for the findings, the research also includes views from information managers dealing with core structured data stored in ERPs and other databases. In addition, the results include the basic criteria that can be used to evaluate metrics, in order to classify a metric as a KPI.

The purpose of consumer co-operation: implications for the management and governance of co-operatives

Extant research on consumer co-operation has acknowledged that the corporate purpose of consumer co-operatives deviates significantly from the purpose of investor-owned firms (IOFs – the dominant form in market economies and in theory development in the field of business economics) and also suggested that the management of consumer co-operatives differs from the management of IOFs. Despite this, there is a scarcity of research focusing on the management of consumer co-operatives in general and the ways this different purpose manifests in their management in particular. In other words, research on consumer cooperatives has only started to discover the importance of identifying the premises of these organizations and generating management and organization theories that take them into account. The overall objective of this study is to map out some of the implications that the purpose of consumer co-operation has for the management and governance of consumer co-operatives. To put it more precisely, by combining interview data gathered from Finnish consumer cooperatives (S Group, OP Bank Group and POP Bank) and extant literature, this study aims to generate or elaborate on definitions and outlines of the features that co-operative purpose poses for the strategic management, governance and managerial competence needed for consumer co-operatives. The study consists of two parts. The first part introduces the research topic, methods and publications, as well as discusses the overall outcomes. The second part consists of four publications that address the research questions from different viewpoints. The analyses of this study indicate that due to the purpose of consumer co-operation, the roles of locality and regionality become emphasized in their management. While locality and regionality are potential sources of competitive advantage for consumer co-operatives, geographic boundness sets significant boundary conditions for the strategic management of these organizations. Further, the purpose of consumer co-operation may pose several challenges to governance and set specific competence demands for the managers of these organizations. Associating the observations from various streams of research on management and governance with the purpose of consumer co-operation and examining these issues further, the thesis contributes to elaboration of theory in the field. While the thesis is by no means comprehensive (but instead reflects a co-operative research project in its early stages), it does shed light on some key ideas of management and governance and offers leads to theory and, thereby, will prove useful to elaborators, disseminators and appliers of knowledge on co-operation.
