Ecological and Epidemiological Analyses of Multiple Sclerosis Relapse Rate

The underlying cause of many human autoimmune diseases is unknown, but several environmental factors are implicated in triggering the self-destructive immune reactions. Multiple Sclerosis (MS) is a chronic autoimmune disease of the central nervous system, potentially leading to persistent neurological deterioration. The cause of MS is not known, and apart from immunomodulatory treatments there is no cure. In the early phase of the disease, relapsing-remitting MS (RR-MS) is characterized by unpredictable exacerbations of the neurological symptoms called relapses, which can occur at different intervals ranging from 4 weeks to several years. Microbial infections are known to be able to trigger MS relapses, and the patients are instructed to avoid all factors that might increase the risk of infections and to properly use antibiotics as well as to take care of dental hygiene. Among those environmental factors which are known to increase susceptibility to infections, high ambient air inhalable particulate matter levels affect all people within a geographical region. During the period of interest in this thesis, the occurrence of MS relapses could be effectively reduced by injections of interferon, which has immunomodulatory and antiviral properties. In this thesis, ecological and epidemiological analyses were used to study the possible connection between MS relapse occurrence, population level viral infections and air quality factors, as well as the effects of interferon medication. Hospital archive data were collected retrospectively from 1986-2001, a period in time ranging from when interferon medication first became available until just before other disease-modifying MS therapies arrived on the market. The grouped data were studied with logistic regression and intervention analysis, and individual patient data with survival analysis. Interferons proved to be effective in the treatment of MS in this observational study, as the amount of MS exacerbations was lower during interferon use as compared to the time before interferon treatment. A statistically significant temporal relationship between MS relapses and inhalable particular matter (PM₁₀) concentrations was found in this study, which implies that MS patients are affected by the exposure to PM₁₀. Interferon probably protected against the effect of PM₁₀, because a significant increase in the risk of exacerbations was only observed in MS patients without interferon medication following environmental exposure to population level specific viral infections and PM₁₀. Apart from being antiviral, interferon could thus also attenuate the enhancement of immune reactions caused by ambient air PM₁₀. The retrospective approach utilizing carefully constructed hospital records proved to be an economical and reliable source of MS disease information for statistical analyses.

A Communication Middleware Quality Enhancement with Qt Framework

In this thesis, a Peer-to-Peer communication middleware for mobile environment is developed using the Qt framework and the Qt Mobility extension. The Peer-to-Peer middleware – called as PeerHood – is for service sharing in network neighborhood. In addition, the PeerHood enables service connectivity and device monitoring functionalities. The concept of the PeerHood is already available in native C++ implementation on Linux platform using services from the platform. In this work, the PeerHood concept is remade to be based on use of the Qt framework. The objective of the new solution is to increase PeerHood quality with using functionalities from the Qt framework and the Qt Mobility extension. Furthermore, by using the Qt framework, the PeerHood middleware can be implemented to be portable cross-platform middleware. The quality of the new PeerHood implementation is evaluated with defined quality factors and compared with the existing PeerHood. Reliability, CPU usage, memory usage and static code analysis metrics are used in evaluation. The new PeerHood is shown to be more reliable and flexible that the existing one.

Enhancement of water removal in the press section

The effectiveness of water removal on press section is very important for a paper and board machine’s functioning, efficiency and economy. Today, the most effective method for wet pressing is shoe press technology. Metso has carried out a number of studies concerning anew type of water removal method for a press section, which has also been patented. These studies include rough sketches and some test runs. These issues form the basis of this thesis. The objective of this work was to gather together information for a new and enhanced waterremoval method for a press section by studying the functioning of the device andcarrying out test runs. This method is referred to here as Hydronip. The main goal was tobuild a functional test site which fulfills all the necessary requirements and has all thenecessary information gathering devices. The design process was carried out by emphasizing the safety aspects. The goal was also to gather together information about the nip structure in running conditions, the seal function, and to carry out the nip tests with paper or board wads. This thesis consists of a theory part, the design and construction of the test site, and carrying out test runs through information gathering. The theory part consists of the principals of water removal from a press section, Hydronip construction, and the requirements for the test place. The safety aspects were taken into account especially in test runs, but also in the assembly stages. The design and construction of the test site includes the selection of equipment and surroundings that are needed for managing the test runs in the best possible way at certain premises. The test site included the equipment that was already on the premises. Some equipment could be used as it was but some equipment had to be manufactured or modified from existing equipment. A functional test site with information gathering devices was accomplished as a result of thethesis. Test runs demonstrated that the Hydronip concept is, at least on a small scale,functional. Short-term tests for seal functioning showed that the seal can be lubricatedsufficiently under different kinds of nip load situations. Wad tests demonstrated that the metal belt is durable against different sizes of external particles. The seal also endured wad tests even though the pressure impacts impaired the lubrication. MTS tests showing dry content increases, combined with a rough cost calculation and the basic function of the machine in test runs, show that with some further study Hydronip could be a promising new product for water removal from a paper or board machine’s press section.

Smart homes as service platforms. Research report of ÄLYKOP sub-project “Competitive advantage from customer value”

In this report, we summarize results of our part of the ÄLYKOP-project on customer value creation in the intersection of the health care, ICT, forest and energy industries. The research directs to describe how industry transformation and convergence create new possibilities, business opportunities and even new industries.The report consists of findings which are presented former in academic publications. The publication discusses on customer value, service provision and resource basis of the novel concepts through multiple theorethical frameworks. The report is divided into three maim sections which are theoretical background, discussion on health care industry and evaluations regarding novel smart home concepts. Transaction cost economics and Resource- Based view on the firm provides the theoretical basis to analyze the prescribed phenomena. The health care industry analysis describes the most important changes in the demand conditions of health care services, and explores the features that are likely to open new business opportunities for a solution provider. The third part of the report on the smart home business provides illustrations few potential concepts that can be considered to provide solutions to economical problems which arise from aging of population. The results provide several recommendations for the smart home platform developers in public and private sectors. By the analysis, public organizations dominate service provision and private markets are emergent state at present. We argue that public-private partnerships are nececssary for creating key suppliers. Indeed, paying attion on appropriate regulation, service specifications and technology standards would foster diffusion of new services. The dynamics of the service provision networks is driven by need for new capabiltities which are required for adapting business concepts to new competitive situation. Finally, the smart home framework revealed links between conventionally distant business areas such as health care and energy distribution. The platform integrates functionalities different for purposes which however apply same resource basis.

The Peace and Security Council of the African Union : its relationship with the United Nations, African Union and sub-regional mechanisms

Avhandlingen undersöker den Afrikanska Unionens freds- och säkerhetsråd och dess roll i framhävandet och upprätthållandet av fred, säkerhet och stabilitet i Afrika. Detta freds- och säkerhetsråd etablerades formellt 2004 och opererar under den Afrikanska Unionen (AU) som å sin sida upprättades 2002. Den Afrikanska Unionens freds- och säkerhetsråds roll i framhävandet av fred, säkerhet och stabilitet gör rådet till en hörnsten inom ramen för konfliktförebyggande och -hantering, samt konfliktlösning på den afrikanska kontinenten. Den Afrikanska Unionens freds- och säkerhetsråd spelar också en högst viktig roll i implementeringen av ansvaret att beskydda civilbefolkningen i konfliktsituationer. För uppfyllandet av sitt mandat att framhäva och upprätthålla fred, säkerhet och stabilitet i Afrika krävs det att freds- och säkerhetsrådet samarbetar med andra institutioner och mekanismer som handhar internationella och regionala freds- och säkerhetsärenden. Avhandlingen analyserar tre dimensioner av denna typ av relationer som freds- och säkerhetsrådet bör etablera med dessa organ och mekanismer för att kunna utföra sitt mandat effektivt. Först analyseras relationen mellan Afrikanska Unionens freds- och säkerhetsråd och Förenta Nationernas säkerhetsråd som också beskrivs i artikel 17 (1) i protokollet som förde till etablerandet av AU:s freds- och säkerhetsråd. Analysen understryker FN:s säkerhetsråd som det organ som bär det primära ansvaret i förhållande till fred och säkerhet, medan AU:s freds- och säkerhetsråd fungerar som en kompletterande komponent i sin roll som ett regionalt organ. Avhandlingen fortsätter med att analysera förhållandet mellan AU:s freds- och säkerhetsråd och andra organ inom AU, samt andra relevanta institutioner som framgår av artikel 10, 18 (1), 19 och 20 i protokollet för rådets etablerande. Avhandlingen diskuterar i detalj hur samarbetet mellan AU:s freds- och säkerhetsråd och dessa institutioner och organ kunde förstärkas till fördel för effektivt framhävande och upprätthållande av fred och säkerhet i Afrika. Slutligen analyserar avhandlingen samarbetet mellan AU:s freds- och säkerhetsråd och sub-regionala mekanismer etablerade under regionala ekonomiska gemenskaper som beskrivs i artikel 16 i protokollet för etablerandet av rådet. Avhandlingen diskuterar i detalj rollen för de sub-regionala mekanismerna i den afrikanska freds- och säkerhetsarkitekturen. Avhandlingen diskuterar vidare förhållandet mellan de sub-regionala mekanismerna och den afrikanska stand-by styrkan ASF och förutsättningarna för detta arrangemang att bemöta afrikanska konflikter. Avhandlingen fokuserar också på en harmoniserings- och samarbetsprocess i förhållande till de sub-regionala mekanismerna, de regionala ekonomiska gemenskaperna och den Afrikanska Unionens freds- och säkerhetsråd. Kort sagt beskriver avhandlingen hur förhållandet mellan AU:s freds- och säkerhetsråd och de ovan nämnda organ och mekanismer har en faktisk och potentiell möjlighet att effektivt bidra till fred, säkerhet och stabilitet i Afrika. Avhandlingen identifierar utmaningarna kring att göra detta till ett fungerande förhållande samtidigt som den genererar både generella och specifika rekommendationer om hur dessa utmaningar bäst kan bemötas. Några av dessa utmaningar utgörs av följande aspekter: konflikten mellan AU:s och FN:s reglemang i bemötandet av freds- och säkerhetsutmaningar; de olika metoderna i FN och AU vid implementeringen av principen av universell jurisdiktion; konflikten mellan de olika mandaten som AU:s freds- och säkerhetsråd och FN:s säkerhetsråd har i förhållande till implementeringen av principen om intervention; och konflikten mellan lagarna och metoderna i förhållande till AU:s freds- och säkerhetsråd och de regionala mekanismerna. En av de huvudsakliga rekommendationerna i avhandlingen i bemötandet av de ovan nämnda utmaningarna är att harmonisera de olika systemen för att försäkra att det föreligger ett samordnat bemötande av konflikter i Afrika. Efter att ha identifierat luckorna i AU:s freds- och säkerhetsprotokoll med speciell fokus på förhållandet mellan rådet och de relevanta organen och mekanismerna rekommenderar avhandlingen ett antal tillägg och modifieringar till instrumentet ifråga för att effektivera, stärka och upprätthålla detta förhållande. Avhandlingen föreslår att dessa tillägg och modifieringar skulle företas under 2014 då detta år markerar 10 år efter att AU:s freds- och säkerhetsråd etablerades. Idén bakom detta företagandet ligger i att 10 år torde vara en tillfredställande tidsperiod för att mäta hur freds- och säkerhetsrådet har fungerat och hur dess förhållande med de relevanta institutionerna och mekanismerna kunde förbättras. Avhandlingen representerar den bredaste och nyaste studien inom ramen för artikel 16, 17, 18, 19 och 20 i protokollet för AU:s freds- och säkerhetsråd och introducerar ett innovativt bemötande av utmaningar till fred, säkerhet och stabilitet på den afrikanska kontinenten. Avhandlingen bidrar till teorin och praxisen i AU:s freds- och säkerhetsråd vilket kan vara av intresse för både forskare och praktiker i folkrätt såväl som i internationella freds- och säkerhetsstudier, speciellt i Afrika.

Gelatin as an additive in bio-based barrier films

The main objective of the present study was to verify the approach on starch-gelatin blending for the paperboard coating formulations with enhanced barrier and mechanical properties. Based on that, another objective was to find out, how the approach will function with wood-based polysaccharides (CMC, EHEC and HPC) by analyzing their barrier properties and convertibility. The last objective was to find out, if pigments can be used in the composition of polysaccharide-protein blends without causing any negative effect on stated properties. The whole process chain of the barrier coating development was studied in the research. The methodology applied included pilot-scale coating and converting trials for the evaluation of mechanical properties of obtained coatings, namely their exposure to cracking with the loss of barrier properties. The results obtained indicated that the combination of starch with gelatin, in fact, improves the grease barrier properties and flexibility of starch-based coatings, thereby confirming the offered approach. The similar results were obtained for CMC, exhibited elevated barrier properties and surface coverage, proving that the approach also functions with wood-based polysaccharides. The introduction of equal amounts of talc gave various effects at different gelatin dosages on barrier properties of wood-based polysaccharides. Mainly, the elevation of grease barrier properties was observed. The convertibility of talc-filled coatings was not sufficient.
