Developing nations vary in data usage techniques with respect to developed nations because of lack of standard information technology architecture. With the concept of globalization in the modern times, there is a necessity of information sharing between different developing nations for better advancements in socio-economic and science and technology fields. A robust IT architecture is needed and has to be built between different developing nations which eases information sharing and other data usage methods. A framework like TOGAF may work in this case as a normal IT framework may not fit to meet the requirements of an enterprise architecture. The intention of the thesis is to build an enterprise architecture between different developing nations using a framework TOGAF

Tämän diplomityön tavoitteena on selvittää sulfaattisellutehtaan hajukaasujen syntyminen, tyypilliset keräilykohteet, keräilyjärjestelmät sekä hajukaasujen käsittely. Työn aihepiiri on ajankohtainen ja tärkeä uuden BAT-asiakirjan voimaan tulon myötä. BAT-asiakirja määrit-telee parhaiten käytettävissä olevan tekniikan näiden kaasujen keräilylle, käsittelylle ja määrää päästötason. Asiakirja määrittelee Euroopan Unionin jäsenmaiden alueella toimivien tehtaiden ympäristöluvat päästötasojen osalta. Uuden BAT-asiakirjan myötä tehtaat jou-tuvat tarkastelemaan päästötasonsa ja mahdollisesti lisäämään hajukaasujen keräilykohteita, joka avaa markkinapotentiaalia hajukaasujärjestelmien toimittajille. Työn kirjallisuusosassa selvitetään hajukaasujen muodostumista, tyypillisiä keräilykohteita sekä käsittelyä ja turvallisuutta. Lisäksi kirjallisuusosuudessa perehdytään tarkemmin BAT-asiakirjaan ja käydään läpi uusimman version tuomia muutoksia ja vaatimuksia hajukaasujen käsittelylle ja keräilylle. Työn tutkimusosuus pohjautuu erääseen Aasiassa sijaitsevaan sulfaattisellutehtaaseen. Tut-kimusosuutta varten tehtaalle toteutettiin vierailu, jonka aikana perehdyttiin tehtaan ole-massa olevaan laimeiden hajukaasujen järjestelmään. Tarkoituksena oli selvittää nykyinen keräilyjärjestelmä, järjestelmän toimivuus, mahdolliset puutteet ja puuttumattomat keräily-kohteet. Lisäksi tavoitteena oli käydä läpi järjestelmän turvallisuuteen liittyviä seikkoja. Diplomityön lopuksi, toteutetun tutkimusosuuden pohjalta, esitellään vaihtoehtoja ja mah-dollisuuksia kyseisen tehtaan järjestelmän parantamiseksi. Tutkimustuloksena selvisi, että tehtaalla on ongelmia tietyissä kohdin järjestelmää, jotka vaatisivat järjestelmän päivittä-mistä nykyisten suositusten mukaisiksi.

This study presents an agile tool set for the business modeling in companies, entering the turbulent environment. The study’s aim is to explore business modeling techniques and their tooling by utilizing a case study of a Finnish media monitoring company, expanding to the Russian market. This work proposes a tailored “two-approach” of business modeling development that analyzes both the past and future conditions of two key factors of business modeling for companies – internal and external environments. The study explores a case company by investigating the benefits and disadvantages of firm’s present business modeling tools, developing a new tooling and applying it to the case company. Among primary data utilization, such as interviews with media monitoring industry analysts and representatives of the competing companies, and academic experts, study leans up on the comprehensive analysis of Russian media monitoring niche and its players. This study benefits the business modeling research area and combines traditional analysis tools, such as market, PESTLE and competitor analyses, in a systemic manner, with the business modeling techniques. This transformation proceeds through applying of the integrated scenario, heat map and critical design issues’ analyses in the societal, industrial and competitive context of turbulent environments. The practical outcome of this approach is the development of agile business modeling tool set, customizable by company’s requirements.

Adenoviral vectors are currently the most widely used gene therapeutic vectors, but their inability to integrate into host chromosomal DNA shortened their transgene expression and limited their use in clinical trials. In this project, we initially planned to develop a technique to test the effect of the early region 1 (E1) on adenovirus integration by comparing the integration efficiencies between an E1-deleted adenoviral vector (SubE1) and an Elcontaining vector (SubE3). However, we did not harvest any SubE3 virus, even if we repeated the transfection and successfully rescued the SubE1 virus (2/4 transfections generated viruses) and positive control virus (6/6). The failure of rescuing SubE3 could be caused by the instability of the genomic plasmid pFG173, as it had frequent intemal deletions when we were purifying It. Therefore, we developed techniques to test the effect of E1 on homologous recombination (HR) since literature suggested that adenovirus integration is initiated by HR. We attempted to silence the E1 in 293 cells by transfecting E1A/B-specific small interfering RNA (siRNA). However, no silenced phenotype was observed, even if we varied the concentrations of E1A/B siRNA (from 30 nM to 270 nM) and checked the silencing effects at different time points (48, 72, 96 h). One possible explanation would be that the E1A/B siRNA sequences are not potent enough to Induce the silenced phenotype. For evaluating HR efficiencies, an HR assay system based on bacterial transfonmatJon was designed. We constmcted two plasmids ( designated as pUC19-dl1 and pUC19-dl2) containing different defective lacZa cassettes (forming white colonies after transformation) that can generate a functional lacZa cassette (forming blue colonies) through HR after transfecting into 293 cells. The HR efficiencies would be expressed as the percentages of the blue colonies among all the colonies. Unfortunately, after transfonnation of plasmid isolated from 293 cells, no colony was found, even at a transformation efficiency of 1.8x10^ colonies/pg pUC19, suggesting the sensitivity of this system was low. To enhance the sensitivity, PCR was used. We designed a set of primers that can only amplify the recombinant plasmid fomied through HR. Therefore, the HR efficiencies among different treatments can be evaluated by the amplification results, and this system could be used to test the effect of E1 region on adenovirus integration. In addition, to our knowledge there was no previous studies using PCR/ Realtime PCR to evaluate HR efficiency, so this system also provides a PCR-based method to carry out the HR assays.
