The objective of this study was to evaluate the influence of vitamin C (VC), vitamin E (VE), and two selenium sources on the performance, yield, and composition of Nile tilapia fillet. The experiment was conducted in a completely randomized design consisting of six treatments with the addition of 100, 200, and 400 mg kg-1 VC and VE and 0.1, 0.2, and 0.4 of two sources of selenium. Each treatment had five replicates of 30 fish each. The diet with 200 mg kg-1 VC and VE + 0.2 mg.k-1 organic selenium resulted in weight gain, length gain, and feed conversion ratio similar to that of the treatment with 400 mg kg-1 VC and VE + 0.4 mg kg-1 organic or inorganic selenium. The addition of organic selenium to the diet improved the weight gain and feed conversion ratio in comparison with the addition of inorganic selenium. The diet with 0.2 mg kg-1 organic selenium showed glutathione peroxidase level equal to the diet with 0.4 mg kg-1 of inorganic selenium. Carcass and fillet yields were not affected by treatments; however, there was treatment effect on the fillet's chemical composition.

Hybridiajoneuvosovellukset vaativat usein sekä korkea- että matalajännitejärjestelmän. Korkeajännitejärjestelmä sisältää yleensä energiavaraston, joka on joko superkondansaattori tai korkeajänniteakusto, dieselgeneraattorin tai range extenderin ja ajokäytön. Korkeajännitejärjestelmään liitetään usein myös erilaisia apukäyttöjä kuten kompressoreita ja hydraulipumppuja. Matalajännitejärjelmä koostuu yleensä ohjausyksiköistä, ajovaloista, yms. laitteista. Perinteisesti matalajännitejärjestelmää on syötetty dieselmoottorin laturista, mutta korkeajännitejärjestelmien myötä DC/DC-hakkurin käyttäminen korkea- ja matalajännitejärjestelmien välillä on herättänyt kiinnostusta, koska tällöin laturin voisi poistaa ja matalajänniteakustoa pienentää. Tässä työssä kuvatun monilähöisen tehonmuokkaimen invertterisilta soveltuu apukäyttöjen ajamiseen, ja erotettu DC/DC-hakkuri matalajännitejärjestelmän syöttämiseen. Tässä työssä käydään läpi edellä mainitun tehonmuokkaimen suunnittelu, keskittyen eritoten laitteen korkeajänniteosien mitoitukseen ja termiseen suunniteluun. DC/DC-hakkurin osalta perinteisiä piistä valmistettuja IGBT transistoreja vertaillaan piikarbidi MOSFET transistoreihin. Lämpömallilaskujen paikkaansapitävyyttä tutkitaan suorittamalla prototyyppilaitteelle hyötysuhdemittaus, jonka tuloksia verrataan laskettuihin tuloksiin. Lämpömallin parannusmahdollisuuksia käsitellään myös hyötysuhdemittauksen tulosten perusteella.

One of the main features that confer high quality to the seed is its genetic purity, in which one of the major causes of contamination is the self-pollination of the female parent. Up to date, there is no accurate and fast methods for detecting such contamination. Thus, this work was carried out to certify the genetic purity in seeds of hybrid maize using different biochemical and DNA-based markers. Two single-cross hybrids and their parental lines derived from the maize breeding program at UFLA were evaluated by isoenzymatic pattern of alcohol dehydrogenase (ADH), esterase (EST), acid phosphatase (ACP), glutamate-oxaloacetate transaminase (GOT), malate dehydrogenase (MDH), isocitrate dehydrogenase (IDH), phosphoglucomutase (PGM), 6-phosphoglucomate dehydrogenase (PGDH), catalase (CAT) and ß-glucosidade (ßGLU) and by microsatellites markers. The enzymatic systems that were able to distinguish the hybrids from their parental line were the catalase, the isocitrate dehydrogenase and the esterase. The esterase showed a Mendelian segregation pattern for UFLA 8/3 hybrid, that enables a safer genetic purity certificate. Microsatellites were able to differentiate the hybrid lines and the respective parental lines. Moreover, this technique was fast, precise and without environment effects. For microsatellites, the amplification pattern was identical when young leaves or seeds were used as DNA source. The possibility of using seeds as DNA source would accelerate and facilitate the role process of the genetic purity analysis.

Yrityksen selviytyminen ja menestyminen ovat riippuvaisia sen kyvystä innovoida, luoda tietoa ja hyödyntää tietämystä ja keksintöjä (Dunk ja Kilgore 2001). Yrityksen menestyminen erityisesti korkean teknologian alalla on siten suoraan riippuvainen sen T&T:stä, johon tehdyt investoinnit tuovat merkittäviä taloudellisia etuja yritykselle uusien tuotteiden, palveluiden ja prosessien muodossa (McEvily ja Chakravarthy 1999). Teknologinen etumatka ja sen tuotteistaminen innovatiivisiksi tarjoamiksi mahdollistaa monopolististen etujen saavuttamisen yrityksen kansainvälisessä kilpailussa (Lall 1977). Tämä kaltainen kilpailuetu voidaan saavuttaa yrityksen kyvyllä yhdistää maantieteellisesti hajautettu T&T:nsä tehokkaaksi verkostoksi (Porter 1986). Boehen (2008) mukaan T&T:n globalisoitumista voidaan johtaa eri hallintömuodoilla: T&T:n kansainvälistymisellä, T&T:n ulkomaille sijoittamisella ja T&T ulkomaille ulkoistamisella. T&T:n globalisoituminen on osa 2000-luvun taloudellista muutosta, ja sille on esitetty useita vaikuttavia tekijöitä, kuten kustannuserot, työvoimaresurssit, erityisosaamiskeskukset, paikallinen teknologia osaaminen ja kohdemarkkinoiden potentiaali (bardhan 2006; Norwood, ym. 2006; von Zedtwitz ja Gassmann 2002). Tutkimuksen on osoitettu eroavan tuotekehityksestä ja eri tekijöiden on osoitettu vaikuttavan niihin (von Zedtwitz ja Gassmann 2002; Leifer ja Triscari 1987). Samoin T&T on osoitettu olevan jatkumo perustavanlaatuisesta soveltavaan ja lääkekehityksen muodostavan vastaavan T&T jatkumon (Lall 1980; Iansiti 1993), jonka yksittäiset osat vaikuttavat sen hallintomuotoon. Tutkimus esittää eri tekijöitä voivan hyödyntää hallintomuodosta riippuen. Tätä tutkimusta varten tutkija haastatteli lääketeollisuuden johtajia Kiinassa vahvistaakseen tai hylätäkseen eri tekijöitä ja niiden suhdetta lääketeollisen T&T:n hallintomuotoihin. Markkinoiden todettiin olevan ensisijainen tekijä mutta myös kustannuserojen, insentiivien, työvoimaresurssien ja erityisosaamiskeskusten merkitys T&T:n globalisoitumiseen vaikuttavina tekijöinä vahvistettiin yhdessä perusvaatimusten ja riskitekijöiden kanssa. Tutkimuksessa vahvistetaan myös lääketeollisen T&T-jatkumon vaikutus ja esitetään viitekehys hallintomuodoille.

Firm's survival and success, which are dependent on its ability to innovate, to create knowledge and to capitalize on inventions and know-how, is in essence directly linked to its R&D process (Dunk and Kilgore 2001). Especially in technology driven industries, such as the pharmaceuticals, there are significant positive returns to R&D investments through introduction of new or improved products and services (McEvily and Chakravarthy 1999). Technological lead and its transformation to innovative products as fruits of corporate R&D can be seen as monopolistic advantage that helps enterprises to compete in today’s market (Lall 1977). This competitive advantage can be derived from corporation's ability to integrate its activities across geographic locations (Porter 1986). According to Boehe (2008) globalization of R&D can executed with different governance forms: R&D internationalization, R&D offshoring or R&D offshore outsourcing. Globalization of R&D is intervened with the changes in global economy of the 21st century. Some studies argue for its influencing factors to be access to vast skilled labor pools and centers of excellence (Bardhan 2006). Other studies indicate the R&D cost differentials between countries to be the major expected benefit (Norwood et al. 2006). Von Zedtwitz and Gassmann (2002) presented benefits as divided to accessing markets and customers or to accessing local science and technology. This study proposes that based on governance form distinct factor derived benefits can be capitalized. To corroborate or refute factors and their relations on R&D globalization governance forms, an empirical study based on expert interviews of pharmaceutical directors was conducted in the People's Republic of China. The market was found to be the major influencing factor. Local requirements and adaptation were corroborated as factors connected with markets. Furthermore, influencing factors, such as labour, centers of excellence, cost, financial incentives were corroborated together with conditional and risk factors. Furthermore this research argues that the globalization of pharmaceutical R&D is dependent on the financial, scientific and operational requirements of the drug discovery stage. And thus establishes the influence of drug discovery's stages continuum on pharmaceutical R&D globalization. Finally, a R&D globalization governance form decision framework is proposed based on the frameworks presented in literature and author's corroborated empirical findings.

This thesis examines Death of a Ghost (1934), Flowers for the Judge (1935), Dancers in Mourning (1937), and The Fashion in Shrouds (1938), a group of detective novels by Margery Allingham that are differentiated from her other work by their generic hybridity. The thesis argues that the hybrid nature of this group of Campion novels enabled a highly skilled and insightful writer such as Allingham to negotiate the contradictory notions about the place of women that characterized the 1930s, and that in dOing so, she revealed the potential of one of the most popular and accessible genres, the detective novel of manners, to engage its readers in a serious cultural dialogue. The thesis also suggests that there is a connection between Allingham's exploration of modernity and femininity within these four novels and her personal circumstances. This argument is predicated upon the assumption that during the interwar period in England several social and cultural attitudes converged to challenge long-held beliefs about gender roles and class structure; that the real impact of this convergence was felt during the 1930s by the generation that had come of age in the previous decade-Margery Allingham's generation; and that that generation's ambivalence and confusion were reflected in the popular fiction of the decade. These attitudes were those of twentieth-century modernity--contradiction, discontinuity, fragmentation, contingency-and in the context of this study they are incorporated in a literary hybrid. Allingham uses this combination of the classical detective story and the novel of manners to examine the notion of femininity by juxtaposing the narrative of a longstanding patriarchal and hierarchical culture, embodied in the image of the Angel in the House, with that of the relatively recent rights and freedoms represented by the New Woman of the late nineteenth-century. Pierre Bourdieu's theory of social difference forms the theoretical foundation of the thesis's argument that through these conflicting narratives, as well as through the lives of her female characters, Allingham questioned the Hsocial myth" of the time, a prevailing view that, since the First World War, attitudes toward the appropriate role and sphere of women had changed.

This exploratory, descriptive action research study is based on a survey of a sample of convenience consisting of 172 college and university marketing students, and 5 professors who were experienced in teaching in an internet based environment. The students that were surveyed were studying e-commerce and international business in 3^^ and 4*'' year classes at a leading imiversity in Ontario and e-commerce in 5^ semester classes at a leading college. These classes were taught using a hybrid teaching style with the contribution of a large website that contained pertinent text and audio material. Hybrid teaching employs web based course materials (some in the form of Learning Objects) to deliver curriculimi material both during the attended lectures and also for students accessing the course web page outside of class hours. The survey was in the form on an online questionnaire. The research questions explored in this study were: 1. What factors influence the students' ability to access and learn from web based course content? 2. How likely are the students to use selected elements of internet based curriculum for learning academic content? 3. What is the preferred physical environment to facilitate learning in a hybrid environment? 4. How effective are selected teaching/learning strategies in a hybrid environment? The findings of this study suggest that students are very interested in being part of the learning process by contributing to a course web site. Specifically, students are interested in audio content being one of the formats of online course material, and have an interest in being part of the creation of small audio clips to be used in class.

The synthesis of 3-ethynylthienyl- (2.07), 3-ethynylterthienyl- (2.19) substituted qsal [qsalH = N-(8-quinolyl)salicylaldimine] and 3,3' -diethynyl-2,2' -bithienyl bridging bisqsal (5.06) ligands are described along with the preparation and characterization of eight cationic iron(III) complexes containing these ligands with a selection of counteranions [(2.07) with: SCN- (2.08), PF6- (2.09), and CI04- (2.10); (2.19) with PF6 - (2.20); (5.06) with: cr (5.07), SeN- (5.08), PF6- (5.09), and CI04- (5.10)]. Spin-crossover is observed in the solid state for (2.08) - (2.10) and (5.07) - (5.10), including a ve ry rare S = 5/2 to 3/2 spin-crossover in complex (2.09). The unusal reduction of complex (2.10) produces a high-spin iron(I1) complex (2.12). Six iron(II) complexes that are derived from thienyl analogues of bispicen [bispicen = bis(2-pyridylmethyl)-diamine] [2,5-thienyl substituents = H- (3.11), Phenyl- (3.12), 2- thienyl (3.13) or N-phenyl-2-pyridinalimine ligands [2,5-phenyl substituents = diphenyl (3.23), di(2-thienyl) (3.24), 4-phenyl substituent = 3-thienyl (3.25)] are reported Complexes (3.11), (3.23) and (3.25) display thermal spin-crossover in the solid state and (3.12) remains high-spin at all temperatures. Complex (3.13) rearranges to form an iron(II) complex (3.14) with temperature dependent magnetic properties be s t described as a one-dimensional ferromagnetic chain, with interchain antiferromagnetic interactions and/or ZFS dominant at low temperatures. Magnetic succeptibility and Mossbauer data for complex (3.24) display a temperature dependent mixture of spin isomers. The preparation and characterization of two cobalt(II) complexes containing 3- ethynylthienyl- (4.04) and 3-ethynylterhienyl- (4.06) substituted bipyridine ligands [(4.05): [Co(dbsqh(4.04)]; (4.07): [Co(dbsq)2(4.06)]] [dbsq = 3,5-dbsq=3,5-di-tert-butylI ,2-semiquinonate] are reported. Complexes (4.05) and (4.07) exhibit thermal valence tautomerism in the solid state and in solution. Self assembly of complex (2.10) into polymeric spheres (6.11) afforded the first spincrossover, polydisperse, micro- to nanoscale material of its kind. . Complexes (2.20), (3.24) and (4.07) also form polymers through electrochemical synthesis to produce hybrid metaUopolymer films (6.12), (6.15) and (6.16), respectively. The films have been characterized by EDX, FT-IR and UV-Vis spectroscopy. Variable-temperature magnetic susceptibility measurements demonstrate that spin lability is operative in the polymers and conductivity measurements confirm the electron transport properties. Polymer (6.15) has a persistent oxidized state that shows a significant decrease in electrical resistance.
