Procurement in Project Implementation

Tutkimus keskittyy hankintatoimen kehittämiseen osana laitosprojektien toteutusta. Työ pohjautuu empiiriseltä taustaltaan Pöyry Oyj:n projektiliiketoimintaan ja työn tarkastelunäkökulmaksi onvalittu projektihallinnosta vastaavan yrityksen näkökulma. Tutkimus on hyvin käytännönläheinen ¿ se lähtee hankinnan ja sen seurannan ongelmista ja pyrkii tarjoamaan niihin uudenlaisia ratkaisuja. Pohjimmiltaan tutkimus kuuluu teollisuustalouden piiriin, vaikka tietojärjestelmätieteellä on vahva tukirooli. Työn tavoitteet ja tulokset liittyvät teollisuustaloudelle ominaisesti yrityksen toiminnan kehittämiseen, käytetyt välineet ja ratkaisut puolestaan hyödyntävät tietojärjestelmätieteen antamia mahdollisuuksia. Tutkimuksessa on käytetty konstruktiivista tutkimusotetta, jonka mukaisesti on luotu innovatiivisia konstruktioita ratkaisemaan aitoja reaalimaailman ongelmia ja tätä kautta tuotettu kontribuutioita teollisuustaloudelle. Tavoitteena oli järjestää hankintatoimi ja sen seuranta suurissa laitosprojekteissa tehokkaammin. Tätä varten uudistettiin ensin projektihallinnon ja hankintatoimen toimintaohjeet vastaamaan paremmin nykyajan vaatimuksia. Toimintaohjeiden perusteella ryhdyttiin toteuttamaan hankintaohjelmistoa, joka pystyisi kattamaan kaikki toimintaohjeissa kuvatut piirteet. Lopulta hankintaohjelmisto toi mukanaan uusia piirteitä projektihallintoon ja hankintatoimeen ja nämä sisällytettiin toimintaohjeisiin. Tähän kehitystyöhön ryhdyttiin, jotta laitosprojektien projektihallinto ja hankintatoimi toimisivat paremmin, eli pienemmin kustannuksin tuottaen projekteissa tarvittavat tulokset nopeammin, tarkemmin ja laadukkaammin. Tutkimuksella on kolmenlaisia tuloksia: hankintatoimen parannetut metodit, hankintaohjelmiston pohjana olevat toiminta- ja laskentamallit sekä implementaationa hankintasovellus. Uudistetut projekti- ja hankintaohjeet kuvaavat hankintatoiminnan parannettuja metodeja. Hankintaohjelmistoasuunnitellessa ja kehitettäessä tehdyt kuvaukset sisältävät uusia malleja niin hankintaprosessille kuin hankinnan seuraamiseksi suurissa laitosprojekteissa. Itse ohjelmisto on tuloksena implementaatio, joka perustuu parannettuihin hankintametodeihin ja uusiin toiminta- ja laskentamalleihin. Uudistetut projekti- ja hankintaohjeet ovat olleet käytössä Pöyry Oyj:ssä vuodesta 1991. Vuosien varrella nämä toimintaohjeet ovat auttaneet ja tukeneet satojen laitosprojektientoteutusta ja ylläpitäneet Pöyry Oyj:n kilpailukykyä kansainvälisenä projektitalona. Hankintasovellus puolestaan on ollut käytössä useissa projekteissa ja sen on havaittu pienentävän hankintatoimen suoria työkustannuksia laitosprojekteissa. Sovelluksen katsotaan myös tuovan epäsuoria kustannussäästöjä parempien hankintapäätösten muodossa, mutta näiden säästöjen suuruutta ei pystytä luotettavasti arvioimaan.

Análise estrutural em floresta ombrófila densa de terra firme não explorada, Amazônia Oriental

O estudo teve como objetivo analisar a composição florística e as estruturas horizontal, interna e diamétrica da floresta. A pesquisa foi conduzida na Unidade de Manejo Florestal (UMF) da Fazenda Tracajás (02º35'53"S e 47º47'10"W), Município de Paragominas, Estado do Pará, Brasil. A floresta foi estratificada em três áreas homogêneas, denominadas classes I, II e III de estoques volumétricos, empregando-se análise multivariada: análises de agrupamento e discriminante. Em cada classe de estoque foram instaladas, aleatoriamente, cinco parcelas de 100 x 100 m (1,0 ha) cada uma, para medição dos indivíduos com dap > 15 cm. No centro de cada parcela de 100 x 100 m foi instalada uma subparcela de 10 x 100 m (0,1 ha), para medição dos indivíduos com 5 cm < dap < 15 cm. Nas classes I, II e III de estoques volumétricos das árvores com dap > 15 cm (nível I de inclusão), respectivamente, estimou-se uma densidade total de 322,4; 309,0; e 313,8 indivíduos por hectare, bem como dominância total de 27,36; 27,45; e 25,88 m²/ha e volume de fuste total de 358,69; 328,33; e 308,69 m³/ha. Nas classes I, II e III de estoques volumétricos das árvores com 5 cm < dap < 15 cm (nível II de inclusão), respectivamente, estimaram-se densidade total de 846; 854; e 886 indivíduos por hectare, dominância total de 4,80; 4,93; e 5,46 m²/ha e volume de fuste total de 93,98; 91,23; e 97,61 m³/ha. As espécies de maior valor de importância relativa, Lecythis idatimon (potencial), Rinorea guianensis (não comercial) e Pouteria guianensis (potencial), ocorreram em todos os níveis de inclusão e classes de estoque. As distribuições de diâmetros de todas as espécies e das espécies comerciais com dap > 5 cm, estimadas pela equação de Meyer, confirmaram a tendência exponencial negativa ("J-invertido"). A análise da estrutura da floresta em classes de estoque permitiu melhor conhecimento da composição de espécies e da estrutura fitossociológica, sendo útil na tomada de decisões em planos de manejo de rendimento sustentável.

Human muscle net K(+) release during exercise is unaffected by elevated anaerobic metabolism, but reduced after prolonged acclimatization to 4,100 m

[EN] It was investigated whether skeletal muscle K(+) release is linked to the degree of anaerobic energy production. Six subjects performed an incremental bicycle exercise test in normoxic and hypoxic conditions prior to and after 2 and 8 wk of acclimatization to 4,100 m. The highest workload completed by all subjects in all trials was 260 W. With acute hypoxic exposure prior to acclimatization, venous plasma [K(+)] was lower (P < 0.05) in normoxia (4.9 +/- 0.1 mM) than hypoxia (5.2 +/- 0.2 mM) at 260 W, but similar at exhaustion, which occurred at 400 +/- 9 W and 307 +/- 7 W (P < 0.05), respectively. At the same absolute exercise intensity, leg net K(+) release was unaffected by hypoxic exposure independent of acclimatization. After 8 wk of acclimatization, no difference existed in venous plasma [K(+)] between the normoxic and hypoxic trial, either at submaximal intensities or at exhaustion (360 +/- 14 W vs. 313 +/- 8 W; P < 0.05). At the same absolute exercise intensity, leg net K(+) release was less (P < 0.001) than prior to acclimatization and reached negative values in both hypoxic and normoxic conditions after acclimatization. Moreover, the reduction in plasma volume during exercise relative to rest was less (P < 0.01) in normoxic than hypoxic conditions, irrespective of the degree of acclimatization (at 260 W prior to acclimatization: -4.9 +/- 0.8% in normoxia and -10.0 +/- 0.4% in hypoxia). It is concluded that leg net K(+) release is unrelated to anaerobic energy production and that acclimatization reduces leg net K(+) release during exercise.

Influence of anti-infliximab antibodies and residual infliximab concentrations on the occurrence of acquired drug resistance to infliximab in rheumatoid arthritis patients

Infliximab (IFX) can be immunogenic for humans and lead to the formation of antibodies against IFX (anti-IFX Ab), which could induce acquired IFX resistance.

Benefits from the use of a pimecrolimus-based treatment in the management of atopic dermatitis in clinical practice. Analysis of a Swiss cohort

BACKGROUND: Controlled studies established the efficacy and good tolerability of pimecrolimus cream 1% for the treatment of atopic dermatitis but they may not reflect real-life use. OBJECTIVE: To evaluate the efficacy, tolerability and cosmetic acceptance of a pimecrolimus-based regimen in daily practice in Switzerland. METHODS: This was a 6-month, open-label, multicentre study in 109 patients (55% > or = 18 years) with atopic dermatitis. Pimecrolimus cream 1% was incorporated into patients' standard treatment protocols. RESULTS: The pimecrolimus-based treatment was well tolerated and produced disease improvement in 65.7% of patients. It was particularly effective on the face (improvement rate: 75.0%). Mean pimecrolimus consumption decreased from 6.4 g/day (months 1-3) to 4.0 g/day (months 3-6) as disease improved. Most patients (74.1%) rated their disease control as 'complete' or 'good' and 90% were highly satisfied with the cream formulation. CONCLUSION: The use of a pimecrolimus-based regimen in everyday practice was effective, well tolerated and well accepted by patients.

Contrast enhanced ultrasound eases interpretation of an unclear renal tumor in addition to CT, MRI and histological findings--a case report in a young patient

Renal cancer represents accounts for approximately 3% of all adult malignancies with a rising incidence. Incidental diagnosis is mostly based upon ultrasound (US). US and Computed tomography (CT) are the standard imaging modalities for detecting renal cell cancer (RCC). Differentiation between malignant and benign renal tumors is of utmost importance. Contrast enhanced ultrasound (CUS) seems to be a promising new diagnostic option for diagnosis and preoperative treatment planning for patients with renal cancer. It is an additional examination to baseline ultrasound and CT. We report a case of a 37-year-old woman with a papillary renal cell cancer in which CUS helped to differentiate dignity of the tumor. CUS is an additional examination to baseline ultrasound and CT. It is a less invasive technique than contrast enhanced CT and shows even slight tumor blood flow. In addition it may allow a more rapid diagnosis, because of its bedside availability.

Inhibition of ErbB2/neuregulin signaling augments paclitaxel-induced cardiotoxicity in adult ventricular myocytes

Paclitaxel (Taxol) has been successfully combined with the monoclonal antibody trastuzumab (Herceptin) in the treatment of ErbB2 overexpressing cancers. However, this combination therapy showed an unexpected synergistic increase in cardiac dysfunction. We have studied the mechanisms of paclitaxel/anti-ErbB2 cardiotoxicity in adult rat ventricular myocytes (ARVM). Myofibrillar organization was assessed by immunofluorescence microscopy and cell viability was tested by the TUNEL-, LDH- and MTT-assay. Oxidative stress was measured by DCF-fluorescence and myocyte contractile function by video edge-detection and fura-2 fluorescence. Treatment of ARVM with paclitaxel or antibodies to ErbB2 caused a significant increase in myofilament degradation, similarly as observed with an inhibitor of MAPK-signaling, but not apoptosis, necrosis or changes in mitochondrial activity. Paclitaxel-treatment and anti-ErbB2 reduced Erk1/2 phosphorylation. Paclitaxel increased diastolic calcium, shortened relaxation time and reduced fractional shortening in combination with anti-ErbB2. A minor increase in oxidative stress by paclitaxel or anti-ErbB2 was found. We conclude, that concomitant inhibition of ErbB2 receptors and paclitaxel treatment has an additive worsening effect on adult cardiomyocytes, mainly discernible in changes of myofibrillar structure and function, but in the absence of cell death. A potential mechanism is the modulation of the MAPK/Erk1/2 signaling by both drugs.
