On Doing Successful ICT Business with Russian Manufacturing Enterprises

This Master’s thesis addresses different approaches using which a foreign IT company could enter Russian manufacturing industry with its enterprise information systems and IT services. In order to define the most suitable market entry approach, several aspects related to Russian manufacturing enterprises are studied. These aspects include challenges of doing ICT business with the previously mentioned enterprises, their perception of ICT role and their ICT preferences, as well as their buying behavior related to acquisition of information systems (IS). The study results show that there are several challenges that can be faced by a foreign IT vendor when starting conducting ICT business with Russian manufacturing enterprises. The results also show that Russian manufacturing industry is still rather immature in sense of business process automation, and its IT buying behavior is rather specific and complicated. The results suggest that an efficient way to approach these enterprises is through a network of trusted partners that consists of reliable Russian IS integrators and business consultants having established connections to Russian manufacturing companies and possessing the needed competence.

Venture capital investment on SME

In addition effect of several other factors is studied in financial crisis. Used determinants are formulated based on three capital structure theories. The pecking order theory concerns favoring on financing source over another. The agency theory and the tradeoff theory concentrate on the search of optimal capital structure. The data of this study consist of financial statement data and results of corporate questionnaire. Regression analysis was used to find out the effects of several determinants. Regression models were formed based on the presented theories. SMEs with and without venture capitalists were considered separately. It was found that venture capitalists have a positive effect on SMEs. Although some results between SMEs with and without venture capitalists were mixed.

Energiatehokkuuden parantaminen teollisuushalleissa - Etelä-Karjalan pienten ja keskisuurten konepaja- ja kunnossapitoyritysten energiaohjelma

Työn tarkoituksena on lisätä Etelä-Karjalan pienten ja keskisuurten konepaja- ja kunnossapitoyritysten tietoisuutta energiatehokkuudesta sekä muista niitä koskettavista energia-asioista. Tietoisuuden lisäämiseksi tutkittiin yritysten energiankulutusta ja kulutustapoja. Tutkimusten pohjalta on kehitetty työkalu, energiaohjelma, jonka avulla tutkimuksen kohteena olleet yritykset voivat itse tarkastella omaa energiankulutustaan ja –tehokkuuttaan. Energiaohjelmaa lähdettiin kehittelemään tutkimuksessa mukana olevan yritysryhmään kuuluvien yritysten haastattelujen pohjalta. Lisäksi muutamiin kohteisiin käytiin tutustumassa energiatehokkuuden mahdollisiin parannuskohtiin paikan päällä. Ohjelma muodostettiin näissä tapahtumissa havainnoitujen tarpeiden pohjalta. Haastattelujen lisäksi tutkimuksessa on käytetty lähteenä myös kirjallisuutta, tärkeimpinä Suomen rakentamismääräyskokoelmat. Ohjelman testausta varten toteutettiin pilottiprojekti, josta saatiin laskennallisesti lupaavia tuloksia. Lämmöntalteenoton lisääminen teollisuushallin poistoilmaan osoittautui hyväksi tavaksi lisätä pilottiprojektissa mukana olleen yrityksen energiatehokkuutta ja hankkeen takaisinmaksuaika jäi alhaiseksi. Jatkoa ajatellen olisi hyvä, jos ohjelmaa voitaisiin kehittää edelleen samankaltaisten kohteiden avulla enemmän yrityksiä palvelevaksi kokonaisuudeksi.

Semi-selective medium for Fusarium graminearum detection in seed samples

Fungi of the genus Fusarium cause a variety of difficult to control diseases in different crops, including winter cereals and maize. Among the species of this genus Fusarium graminearum deserves attention. The aim of this work was to develop a semi-selective medium to study this fungus. In several experiments, substrates for fungal growth were tested, including fungicides and antibiotics such as iprodiona, nystatin and triadimenol, and the antibacterial agents streptomycin and neomycin sulfate. Five seed samples of wheat, barley, oat, black beans and soybeans for F. graminearum detection by using the media Nash and Snyder agar (NSA), Segalin & Reis agar (SRA) and one-quarter dextrose agar (1/4PDA; potato 50g; dextrose 5g and agar 20g), either unsupplemented or supplemented with various concentrations of the antimicrobial agents cited above. The selected components and concentrations (g.L-1) of the proposed medium, Segalin & Reis agar (SRA-FG), were: iprodiona 0.05; nystatin 0,025; triadimenol 0.015; neomycin sulfate 0.05; and streptomycin sulfate, 0.3 added of ¼ potato sucrose agar. In the isolation from seeds of cited plant species, the sensitivity of this medium was similar to that of NSA but with de advantage of maintaining the colony morphological aspects similar to those observed in potato-dextrose-agar medium.

Semi-selective culture medium for Exserohilum turcicum isolation from corn seeds

Northern corn leaf blight, caused by Exserohilum turcicum (Et), is a disease of widespread occurrence in regions where corn, sweetcorn and popcorn are grown. This disease has great potential to cause damage and has been studied for years, but the association of its causal agent with seeds remains unconfirmed. Thus, the availability of a sensitive method to detect and quantify the inoculum in seeds, even at low incidence, is essential. The aim of this study was to develop a method to detect and quantify the presence of the fungus infecting and infesting corn and popcorn seeds. Artificially and naturally infected seeds were employed to develop the medium. The semi-selective medium was composed of carbendazim (active ingredient) (60 mg/L), captan (30 mg/L), streptomycin sulfate (500 mg/L) and neomycin sulfate (600 mg/L) aggregated to the medium lactose casein hydrolysate agar medium. By using this, Et was detected in naturally infected corn seeds, showing 0.124% incidence, in four out of ten analyzed samples. In addition, 1.04 conidia were detected per infested seed. By means of isolation, pathogenicity test, morphological characterization and comparison with descriptions of the species in the literature, the fungus isolated from the seeds was confirmed to be Et. Both infection and infestation were considered low; thus, for studies of Et detection in corn seeds, the use of semi-selective medium and more than 1,200 seeds/sample is suggested.

Switching components for medium voltage drives

Nowadays power drives are the essential part almost of all technological processes. Improvement of efficiency and reduction of losses require development of semiconductor switches. It has a particular meaning for the constantly growing market of renewable sources, especially for wind turbines, which demand more powerful semiconductor devices for control with growth of power. Also at present semiconductor switches are the key component in energy transmission, optimization of generation and network connection. The aim of this thesis is to make a survey of contemporary semiconductor components, showing difference in structures, advantages, disadvantages and most suitable applications. There is topical information about voltage, frequency and current limits of different switches. Study tries to compare dimensions and price of different components. Main manufacturers of semiconductor components are presented with the review of devices produced by them, and a conclusion about their availability was made. IGBT is selected as a main component in this study, because nowadays it is the most attractive component for usage in power drives, especially at the low levels of medium voltage. History of development of IGBT structure, static and dynamic characteristics are considered. Thesis tells about assemblies and connection of components and problems which can appear. One of key questions about semiconductor materials and their future development was considered. For the purpose of comparison strong and weak sides of different switches, calculation of losses of IGBT and its basic competitor – IGCT is presented. This master’s thesis makes an effort to answer the question if there are at present possibilities of accurate selection of switches for electrical drives of different rates of power and looks at future possible ways of development of semiconductor market.

The Interplay between Market Orientation and Entrepreneurial Orientation - Empirical Evidence from SMEs

The purpose of this thesis is to investigate how the dimensions of market orientation and entrepreneurial orientation are carried out in small and medium-sized enterprises (SME). In addition, the research aims to answer how these strategic orientations are apparent in SMEs, how the orientations co-vary, and how the dimensions of orientations are carried out in successful SMEs. The qualitative case study was participated by 16 SMEs. The research sample was gathered trough face-to-face interviews, consisting of Likert scale statements and open-ended questions. The main restriction of implementing market and entrepreneurial orientations in SMEs were scarce resources. Thus, the enterprises were required to make trade-offs between the different dimensios of orientations. Risk-aversive enterprises had emphasis on reactive customer orientation whereas, willing to take risks was generally related to proactiveness. Proactive enterprises utilized interfunctional coordination, and innovativeness was supported by value network coordination. The majority of the successful enterprises were growth-oriented, aiming to be technologial leaders in their industries. The successful firms placed similar emphasis on customer and product orientation.

Energia- ja ilmastotoimenpiteiden käynnistäminen pk-yrityksissä

Tämän diplomityön tarkoituksena oli kehittää toimintamalli pk-yritysten energia- ja ilmastotoimenpiteiden käynnistämiseksi HINKU-kunnissa. Esimerkkiyrityksenä työssä toimi Tehomet Oy:n Parikkalan tehdas. Työssä tutustuttiin ensimmäisenä erilaisiin jo olemassa oleviin toimintamalleihin, hiilijalanjäljen laskentastandardeihin sekä erilaisiin mahdollisuuksiin hiilineutraaliuden saavuttamiseksi. Lisäksi Tehomet Oy:n Parikkalan tehtaalta kerättiin tarvittavaa tietoa yrityksen ja tuotteen hiilijalanjälkien laskentaa varten. Kerätyn tiedon ja jo olemassa olevien standardien ja toimintamallien pohjalta kehitettiin toimintamalli, johon sisältyy laskentataulukko, jonka avulla yritykset voivat laskea hiilijalanjälkensä ja tunnistaa kasvihuonekaasupäästöjen merkittävyyden liiketoimintansa kehittämisen näkökulmasta. Tehomet Oy:n valmistaman puupylvään hiilijalanjälki pieneni merkittävästi, kun laskennassa huomioitiin hiilen sitoutuminen tuotteeseen sekä tuotteen käytöstä poisto. Parikkalan tehtaan tapauksessa suurin yksittäinen kasvihuonekaasujen päästölähde on sähkönkulutus. Energiankulutuksen kannalta merkittävin säästökohde olisi mitä todennäköisimmin teholtaan liian suuresta kompressorista luopuminen. Kasvihuonekaasupäästöjen hiilineutraaliksi saattamiseksi mahdolliset toimenpiteet olisivat tässä tapauksessa hiilivapaan sähkön ostaminen tai päästöjen kompensoiminen ostamalla päästöoikeuksia. Toimintamallin todellinen toimivuus nähdään tulevaisuudessa, kun sitä päästään testaamaan laajemmalti eri aloilla toimiviin yrityksiin.

Energy Efficiency of Pumping Medium Consistency Pulp with Centrifugal Pump

Approximately a quarter of electrical power consumption in pulp and paper industry is used in different pumping systems. Therefore, improving pumping system efficiency is a considerable way to reduce energy consumption in different processes. Pumping of wood pulp in different consistencies is common in pulp and paper industry. Earlier, centrifugal pumps were used to pump pulp only at low consistencies, but development of MC technology has made it possible to pump medium consistency pulp. Pulp is a non-Newtonian fluid, which flow characteristics are significantly different than what of water. In this thesis is examined the energy efficiency of pumping medium consistency pulp with centrifugal pump. The factors effecting the pumping of MC pulp are presented and through case study is examined the energy efficiency of pumping in practice. With data obtained from the case study are evaluated the effects of pump rotational speed and pulp consistency on energy efficiency. Additionally, losses caused by control valve and validity of affinity laws in pulp pumping are evaluated. The results of this study can be used for demonstrating the energy consumption of MC pumping processes and finding ways to improve energy efficiency in these processes.

Cassava starch extraction effluent treatment in a one phase tubular horizontal pilot reactor with support medium

The cassava starch industries generate a large volume of wastewater effluent that, stabilized in ponds, wastes its biogas energy and pollutes the atmosphere. To contribute with the reversion of this reality, this manipueira treatment research was developed in one phase anaerobic horizontal pilot reactor with support medium in bamboo pieces. The reactor was excavated into the ground and sealed with geomembrane in HDPE, having a volume equal to 33.6 m³ and continuous feeding by gravity. The stability indicators were pH, volatile acidity/total alkalinity ratio and biogas production. The statistical analyses were performed by a completely randomized design, with answers submitted to multivariate analysis. The organical loads in COD were 0.556; 0.670; 0.678 and 0.770 g L-1 and in volatile solids (VS) of 0.659; 0.608; 0.570 and 0.761 g L-1 for the hydraulic retention times (HRT) of 13.0; 11.5; 10.0 and 7.0 days, respectively. The reductions in COD were 88; 80; 88 and 67% and for VS of 76; 77; 65 and 61%. The biogas productions relatively to the consumed COD were 0.368; 0.795; 0.891 and 0.907 Lg-1, for the consumed VS of 0.524; 0.930; 1.757 and 0.952 Lg-1 and volumetric of 0.131; 0.330; 0.430 and 0.374 L L-1 d-1. The reactor remained stable and the bamboo pieces, in visual examination at the end of the experiment, showed to be in good physical conditions.
