Laskennallisen läpimenoajan lyhentäminen

Työn tavoitteena oli selvittää yrityksen käytössä olevaa läpimenoajan laskentakaavaa, sekä löytää keinoja ja toimintamalleja läpimenoajan lyhentämiseen lähinnä puolivalmisteiden osalta. Taustalla on konsernin tavoitteet lyhentää läpimenoaikoja. Työ keskittyi kahteen liiketoimintayksikköön, jotka ovat rakennuslukitus ja laitelukitus. Näillä liiketoimintayksiköillä läpimenoajat ovat selvästi konsernin keskiarvoa korkeammat. Ensin selvitettiin nykytilannetta nimikeanalyysien ja haastattelujen avulla. Läpimenoajan laskentakaavan osatekijät esiteltiin. Seuraavaksi tutkittiin vaikutusmahdollisuuksia laskentakaavan osatekijöihin. Lisäksi laadittiin eräkokojen keskinäisten valmistuserien laskentaan LIMIT-tekniikalla toteutettu laskentataulukko, jota hyödyntämällä varastoissa oleviin nimikkeisiin sitoutunutta pääomaa pystytään minimoimaan. Toimenpide-ehdotuksena esitetään vuosia varastoissa seisseiden nimikkeiden hävittämistä, sekä nimikekohtaisten asetusaikojen selvittämistä ja niiden systemaattista lyhentämistä. Lisäksi ehdotetaan siirtymistä omakustannehinnoittelusta keskivarastohinnoitteluun myös puolivalmisteiden kohdalla. Tällöin laskentakaavaan syntyvät vääristymät saadaan poistettua.

Improving the Quality of EEG Data in Patients With Alzheimers Disease Using ICA

Does Independent Component Analysis (ICA) denature EEG signals? We applied ICA to two groups of subjects (mild Alzheimer patients and control subjects). The aim of this study was to examine whether or not the ICA method can reduce both group di®erences and within-subject variability. We found that ICA diminished Leave-One- Out root mean square error (RMSE) of validation (from 0.32 to 0.28), indicative of the reduction of group di®erence. More interestingly, ICA reduced the inter-subject variability within each group (¾ = 2:54 in the ± range before ICA, ¾ = 1:56 after, Bartlett p = 0.046 after Bonfer- roni correction). Additionally, we present a method to limit the impact of human error (' 13:8%, with 75.6% inter-cleaner agreement) during ICA cleaning, and reduce human bias. These ¯ndings suggests the novel usefulness of ICA in clinical EEG in Alzheimer's disease for reduction of subject variability.

Drug-eluting stents compared to bare-metal stents improve short-term survival in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention: a nationwide prospective analysis of the AMIS Plus registry.

BACKGROUND: Recently, it has been suggested that the type of stent used in primary percutaneous coronary interventions (pPCI) might impact upon the outcomes of patients with acute myocardial infarction (AMI). Indeed, drug-eluting stents (DES) reduce neointimal hyperplasia compared to bare-metal stents (BMS). Moreover, the later generation DES, due to its biocompatible polymer coatings and stent design, allows for greater deliverability, improved endothelial healing and therefore less restenosis and thrombus generation. However, data on the safety and performance of DES in large cohorts of AMI is still limited. AIM: To compare the early outcome of DES vs. BMS in AMI patients. METHODS: This was a prospective, multicentre analysis containing patients from 64 hospitals in Switzerland with AMI undergoing pPCI between 2005 and 2013. The primary endpoint was in-hospital all-cause death, whereas the secondary endpoint included a composite measure of major adverse cardiac and cerebrovascular events (MACCE) of death, reinfarction, and cerebrovascular event. RESULTS: Of 20,464 patients with a primary diagnosis of AMI and enrolled to the AMIS Plus registry, 15,026 were referred for pPCI and 13,442 received stent implantation. 10,094 patients were implanted with DES and 2,260 with BMS. The overall in-hospital mortality was significantly lower in patients with DES compared to those with BMS implantation (2.6% vs. 7.1%,p < 0.001). The overall in-hospital MACCE after DES was similarly lower compared to BMS (3.5% vs. 7.6%, p < 0.001). After adjusting for all confounding covariables, DES remained an independent predictor for lower in-hospital mortality (OR 0.51,95% CI 0.40-0.67, p < 0.001). Since groups differed as regards to baseline characteristics and pharmacological treatment, we performed a propensity score matching (PSM) to limit potential biases. Even after the PSM, DES implantation remained independently associated with a reduced risk of in-hospital mortality (adjusted OR 0.54, 95% CI 0.39-0.76, p < 0.001). CONCLUSIONS: In unselected patients from a nationwide, real-world cohort, we found DES, compared to BMS, was associated with lower in-hospital mortality and MACCE. The identification of optimal treatment strategies of patients with AMI needs further randomised evaluation; however, our findings suggest a potential benefit with DES.

The efficiency of indicator groups for the conservation of amphibians in the Brazilian Atlantic Forest

The adequate selection of indicator groups of biodiversity is an important aspect of the systematic conservation planning. However, these assessments differ in the spatial scale, in the methods used and in the groups considered to accomplish this task, which generally produces contradictory results. The quantification of the spatial congruence between species richness and complementarity among different taxonomic groups is a fundamental step to identify potential indicator groups. Using a constructive approach, the main purposes of this study were to evaluate the performance and efficiency of eight potential indicator groups representing amphibian diversity in the Brazilian Atlantic Forest. Data on the geographic range of amphibian species that occur in the Brazilian Atlantic Forest was overlapped to the full geographic extent of the biome, which was divided into a regular equal-area grid. Optimization routines based on the concept of complementarily were applied to verify the performance of each indicator group selected in relation to the representativeness of the amphibians in the Brazilian Atlantic Forest as a whole, which were solved by the algorithm"simulated annealing", through the use of the software MARXAN. Some indicator groups were substantially more effective than others in regards to the representation of the taxonomic groups assessed, which was confirmed by the high significance of data (F = 312.76; p < 0.01). Leiuperidae was considered as the best indicator group among the families analyzed, as it showed a good performance, representing 71% of amphibian species in the Brazilian Atlantic Forest (i.e. 290 species), which may be associated with the diffuse geographic distribution of its species. This study promotes understanding of how the diversity standards of amphibians can be informative for systematic conservation planning on a regional scale.

Speed limit laws in America: economics, politics and geography

The regulation of speed limits in the US had been centralized at the federal level since 1974, until decisions were devolved to the states in 1995. However, the centralization debate has reemerged in recent years. Here, we conduct the first econometric analysis of the determinants of speed limit laws. By using economic, geographic and political variables, our results suggest that geography -which affects private mobility needs and preferences- is the main factor influencing speed limit laws. We also highlight the role played by political ideology, with Republican constituencies being associated with higher speed limits. Furthermore, we identify the presence of regional and time dependence effects. By contrast, poor road safety outcomes do not impede the enactment of high speed limits. Overall, we present the first evidence of the role played by geographical, ideological and regional characteristics, which provide us with a better understanding of the formulation of speed limit policies.

Normal values for pancreatic stone protein in different age groups.

BACKGROUND: Pancreatic stone protein (PSP) has been identified as a promising sepsis marker in adults, children and neonates. However, data on population-based reference values are lacking. This study aimed to establish age-specific reference values for PSP. METHODS: PSP was determined using a specific ELISA. PSP serum concentrations were determined in 372 healthy subjects including 217 neonates, 94 infants and children up to 16 years, and 61 adults. The adjacent categories method was used to determine which age categories had significantly different PSP concentrations. RESULTS: PSP circulating levels were not gender-dependent and ranged from 1.0 to 99.4 ng/ml with a median of 9.2 ng/ml. PSP increased significantly between the age categories, from a median of 2.6 ng/ml in very preterm newborns, to 6.3 ng/ml in term newborns, to 16.1 ng/ml in older children (p < 0.001). PSP levels were higher on postnatal day three compared to levels measured immediately post delivery (p < 0.001). Paired umbilical artery and umbilical vein samples were strongly correlated (p < 0.001). Simultaneously obtained capillary heel-prick versus venous samples showed a good level of agreement for PSP (Rho 0.89, bias 19 %). CONCLUSIONS: This study provides age-specific normal values that may be used to define cut-offs for future trials on PSP. We demonstrate an age-dependent increase of PSP from birth to childhood.

Safety and Immunogenicity of a Recombinant Adenovirus Serotype 35-Vectored HIV-1 Vaccine in Adenovirus Serotype 5 Seronegative and Seropositive Individuals.

BACKGROUND: Recombinant adenovirus serotype 5 (rAd5)-vectored HIV-1 vaccines have not prevented HIV-1 infection or disease and pre-existing Ad5 neutralizing antibodies may limit the clinical utility of Ad5 vectors globally. Using a rare Ad serotype vector, such as Ad35, may circumvent these issues, but there are few data on the safety and immunogenicity of rAd35 directly compared to rAd5 following human vaccination. METHODS: HVTN 077 randomized 192 healthy, HIV-uninfected participants into one of four HIV-1 vaccine/placebo groups: rAd35/rAd5, DNA/rAd5, and DNA/rAd35 in Ad5-seronegative persons; and DNA/rAd35 in Ad5-seropositive persons. All vaccines encoded the HIV-1 EnvA antigen. Antibody and T-cell responses were measured 4 weeks post boost immunization. RESULTS: All vaccines were generally well tolerated and similarly immunogenic. As compared to rAd5, rAd35 was equally potent in boosting HIV-1-specific humoral and cellular immunity and responses were not significantly attenuated in those with baseline Ad5 seropositivity. Like DNA, rAd35 efficiently primed rAd5 boosting. All vaccine regimens tested elicited cross-clade antibody responses, including Env V1/V2-specific IgG responses. CONCLUSIONS: Vaccine antigen delivery by rAd35 is well-tolerated and immunogenic as a prime to rAd5 immunization and as a boost to prior DNA immunization with the homologous insert. Further development of rAd35-vectored prime-boost vaccine regimens is warranted.

Care related pain in rehabilitation after orthopedic trauma: An exploratory study with qualitative data.

OBJECTIVE: Care related pain (CRP) is generally under-estimated and rarely studied in rehabilitation as well as in general medecine. Beliefs about pain influence psychological distress, adjustment to pain and physical disability. In this sense, perceptions of CRP could limit recovery. This exploratory study aims to understand patients' and caregivers' subjective perceptions and beliefs about CRP. PATIENTS AND METHODS: Questionnaires about CRP were submitted to members of the interdisciplinary team of a rehabilitation hospital and to patients with musculoskeletal complaints (cross-sectional design). Twenty patients were also individually interviewed (qualitative data). Four topics were addressed: frequency of CRP, situations and procedures causing CRP, beliefs about CRP and means used to deal with CRP. RESULTS: Seventy-five caregivers and 50 patients replied to the questionnaire. CRP is a very common experience in rehabilitation and it is recognized by both groups. Generally, the situations causing CRP reflect the specificity of rehabilitation (mobilization...) and are similarly perceived by patients and caregivers, with patients considering them as more painful. Beliefs about CRP are clearly different from those usually associated with pain. Both groups point out the utilitarian and the inevitable character of CRP. They differ on that, that patients had a more positive view about CRP. They associate it more often with progress and see it as acceptable at least until a certain limit. They are also able to perceive the richness of means used by physiotherapists to help them coping with CRP. CONCLUSION: Our data may suggest new keys to motivate patient to be active in rehabilitation for example in choosing carefully arguments or words which may fit theirs' beliefs about CRP, or in using various means to manage CRP. Promoting the use of relational competences with chronic pain patients and of a patient-centred approach may also be a concern in training caregivers.

Workgroup climates and employees' counterproductive work behaviors: A social-cognitive perspective

This research examines employees' anticipation of social and self-sanctions as a self-regulatory mechanism linking workgroup climates and counterproductive work behaviors (CWBs) and personality as a limit to these effects. A cross-level study with 158 employees from 26 workgroups demonstrated that in groups with a high compliance climate-a climate emphasizing the importance of complying with organizational rules-employees anticipate more social and self-sanctions, leading those low in conscientiousness and low in agreeableness to engage less frequently in CWBs. In contrast, a high relational climate-a climate emphasizing the importance of positive social relations over self-interest-indirectly unbridles the CWBs of these employees by alleviating the social and self-sanctions they anticipate for CWBs. Climates did not have indirect effects for employees high in agreeableness and high in conscientiousness. These findings elucidate why workgroup climates do not affect the CWBs of all members in the same way.

Identification of novel factors during the establishment of the Casparian strip in the endodermis

Multicellular organisms rely on specialized tissues that allow for the controlled exchange of matter with their surrounding. In order to function properly, these tissues need to establish a tight connection between the individual cells to prevent uncontrolled passive diffusion across the extracellular space. In animals, these connections are called tight and adherens junctions and are a critical feature of epithelia. These connections, however, rely on direct protein-protein interaction of plasma membrane proteins of adjacent cells. Such a mechanism is not possible in plants due to the cell wall, which encases the individual cells. In order to absorb nutrients, while simultaneously preventing uncontrolled diffusion between cells, land plants have evolved the root endodermis, which is functionally equivalent to animal epithelia. Its cells are surrounded by a precisely localized and aligned, ring-like lignin deposition, called the Casparian strip, and therefore tightly connected between each other. Very little was known about the development of the endodermis and the Casparian strip until recently. In the meantime, however, we have identified a family of endodermis- specific proteins, the CASPs, which recruits extracellular proteins the specific Casparian strip membrane domain (CSD) to locally synthesize lignin in the cell wall. Yet, we hardly knew any specifics on how the CSD is initially defined and how the critically important CASPs are being recruited to it. We therefore conducted a forward genetic screen on the localization of CASPI-GFP in order to identify novel mutants, which lack a defined CSD. We identified 48 mutants, which fell into 15 different complementation groups. While some of the isolated genes had previously been identified through different approaches, nine novel genes, which had never been implicated in CSD development and maintenance, were identified. One of them, LORD OF THE RINGS 2 (.LOTR2) is described to greater detail in this work. LOTR2 encodes for EX070A1, a protein of the evolutionary conserved exocyst complex. This complex has frequently been implicated in various secretory processes across kingdoms. In Arabidopsis, it transiently defines the positioning of CASPI-GFP. We have performed a detailed analysis of the dynamics of EX070A1 and CASPI-GFP, including studies with other markers and propose a mechanism, by which the cytosolic EX070A1 transiently defines a plasma membrane domain to recruit transmembrane proteins, which then recruit extracellular enzymes for localized cell wall modification. Considering the ubiquitous expression of EX070A1, we think that this mechanism is potentially of importance not only for the endodermis and the Casparian strip but also for many other tissues, in which the cell wall becomes locally modified. In fact, many other tissues with secondary cell wall modifications contain proteins very similar to the CASPs. It will be interesting to see to which degree this mechanism is employed in other tissues. As for the endodermis, we have now identified the first gene, which is not specific to the endodermis but shows endodermis-specific dynamics. This might give us a better insight on how the plant modulates this ubiquitously present factor in a cell- or tissue-type specific manner. Considering the knowledge, mutants and tools, which are available to us for investigating the endodermis, the Casparian strip, the exocyst complex and EX070A1 might be just the right experimental system to address these questions. -- Les organismes multicellulaires dépendent des tissues spécialisé pour l'échange contrôlé entre eux et leur environnement. Pour leur bon fonctionnement, les cellules de ces tissus ont besoin d'être très étroitement assemblés afin de prévenir la diffusion non-contrôlée à travers l'espace extracellulaire. Chez les animaux, ces connexions sont appelées jonctions serrées et jonctions adhérentes. Ces jonctions dépendent des interactions directes entre les protéines des cellules voisines. Ceci n'est pas possible chez les plantes à cause de la paroi cellulaire qui recouvre chaque cellule individuellement. Pour absorber les nutriments et en même temps empêcher la diffusion non-contrôlé entre cellules, les plantes ont évolué 1'endoderme dans la racine, qui est fonctionnellement équivalent aux épithéliums des animaux. Les cellules de l'endoderme sont ceinturées par une déposition de lignine très précisément localisées comme un anneau et alignées entre les cellules, et qui, donc, connecte étroitement les cellules avoisinante: Le cadre de Caspary. Peu était connu sur le développement de l'endoderme et le cadre de Caspaiy jusqu'à il y a quelques années. Récemment, pourtant, nous avons identifié une famille de protéines spécifiques à l'endoderme, les CASPs, qui définissent le domaine membranaire du cadre de Caspaiy (CSD). Les CASPs recrutent les protéines extracellulaires nécessaire à la synthèse du cadre de Caspary vers une région limité dans la paroi cellulaire. Pourtant, on connaît très peu les processus spécifiques concernant la définition initiale du CSD et comment les CASPs, qui ont une importance cruciale, sont recrutées vers ce domaine. Par conséquent nous avons mené un crible génétique sur la localisation du CASPI- GFP, qui sert comme marqueur pour le CSD. Notre but étant d'isoler de nouveaux mutants affectés dans l'établissement du CSD. Nous avons identifié 48 mutants, en 15 groupes de complémentation. Bien que certains des gènes isolés étaient déjà impliqué dans la formation du cadre de Caspary, neuf nouveaux gènes n'ayant jamais été impliqués dans le développement ou la maintenance du CSD ont pu être identifiés. Un de ces gènes, LORD OF THE RINGS2 (LOTR2) sera décrit plus en détail dans cette étude. LOTR2 code pour EX070A1, qui est une protéine, du complexe exocyste. Ce complexe de protéines a très bien été conservé au cours de l'évolution. Il était souvent impliqué dans plusieurs processus de sécrétion dans toutes les branches de la vie. Chez Arabidopsis, EX070A1 définit la position du CSD d'une façon transitoire et recrute CASP1- GFP. Nous avons mené une analyse détaillée des dynamiques d'EX070Al et CASPI-GFP ainsi que, des études avec des autres mutants. Nous proposons un mécanisme, d'après lequel EX070A1, recruté du cytosol, définit un domaine dans la membrane plasmique pour localiser des protéines transmembranaires, ces dernières ensuite recruteront des enzymes extracellulaires pour la modification locale de la paroi cellulaire. Vu qu'EX070A1 est exprimé dans toute dans la plante, nous pensons que ce mécanisme est potentiellement important non seulement pour l'endoderme et le cadre de Caspary, mais aussi pour les autres tissus où la paroi cellulaire doit être localement modifiée. En effet, plusieurs autres tissus contiennent des protéines très similaires aux CASPs. Il serait intéressant de voir à quelle dégrée ce mécanisme est également utilisé dans ces tissues. En ce qui concerne l'endoderme, nous avons maintenant identifié le premier gène qui n'est pas exprimé spécifiquement dans l'endoderme, mais qui montre tout de même une dynamique caractéristique dans ce tissu. Il serait intéressant de voir comment la plante peut moduler ce facteur omniprésent d'une façon spécifique. Vu les connaissances, les mutants et les outils qu'on a maintenant à notre disposition, l'endoderme et son cadre de Caspary, le complexe exocyste et EX070A1 sont probablement des bons systèmes expérimentaux pour étudier ces questions. -- Identification des nouveaux facteurs pendant l'établissement du cadre de Caspary dans l'endoderme. Lothar Kalmbach, Département de Biologie Moléculaire Végétale (DBMV), Université de Lausanne. Comme tous les autres organismes multicellulaires, les plantes terrestres dépendent de tissus spécialisés pour l'échange contrôlé avec leur environnement. Ces tissus sont importants pour l'absorption des nutriments mais également pour éviter l'influx de composés toxiques. Chez les plantes, ce tissu se trouve dans la racine. C'est l'endoderme. Grâce au cadre de Caspary, qui permet une forte connexion entre les cellules au niveau de leur paroi, l'endoderme empêche les éléments toxiques d'entrer dans le système vasculaire. Depuis quelques années, nous comprenons de plus en plus la nature et la biosynthèse, ainsi que les protéines impliquées dans l'ancrage des enzymes à la membrane plasmique. Nous n'avons eu, par contre, aucune idée sur le mécanisme qui d'abord définit cet endroit dans la membrane plasmique. Nous avons mené un crible génétique sur la localisation de CASPI-GFP, une protéine, qui recrute les enzymes extracellulaires pour la synthèse du cadre de Caspary. Nous avons identifié plusieurs nouveaux gènes qui sont impliqués dans l'intégrité du cadre de Caspary. L'un de ces gènes est EX070A1, qui est un facteur ayant un rôle important lors de la sécrétion des protéines dans tous les organismes eukaryotes. Ces mutants sont gravement affectés au niveau du cadre de Caspary, mais surtout ils ne sont plus capables de localiser CASPI-GFP. Nous avons suivi la dynamique d'EX070Al et de CASP1-GFP en combinaison avec d'autres marqueurs. Nous avons pu montrer que l'accumulation d'EX070Al est spécifique pour l'endoderme et essentielle pour bien localiser CASPI-GFP et donc, le cadre de Caspary. Ces résultats nous aident à mieux comprendre le développement de l'endoderme mais peuvent potentiellement aussi être utilisés pour étudier les modifications de la paroi cellulaire dans d'autres cellules de la plante.

World Polarization in carbon emissions, potential conflict and groups: an updated revision

Typically, conflicts in world environmental negotiations are related, amongst other aspects, to the level of polarization of the countries in groups with conflicting interests. Given the predictable relationship between polarization and conflict, it would seem logical to evaluate the degree to which the distribution of countries – for example, in terms of their CO2 emissions per capita – would be structured through groups which in themselves are antagonistic, as well as their evolution over time. This paper takes the concept of polarization to explore this distribution for the period 1992-2010, looking at different analytic approaches related to the concept. Specifically, it makes a comparative evaluation of the results associated with endogenous multi-polarization measures (i.e. EGR and DER indices), exogenous measures (i.e. Z-K or multidimensional index) and strict bipolarization measures (i.e. Wolfson’s measure). Indeed, the interest lies not only in evaluating the global situation of polarization by comparing the different approaches and their temporal patterns, but also in examining the explanatory capacity of the different proxy groups used as a possible reference for designing global environmental policy from a group premise.

Computing the diameter of Coxeter groups

This thesis addresses the problem of computing the minimal and maximal diameter of the Cayley graph of Coxeter groups. We first present and assert relevant parts of polytope theory and related Coxeter theory. After this, a method of contracting the orthogonal projections of a polytope from Rd onto R2 and R3, d ¸ 3 is presented. This method is the Equality Set Projection algorithm that requires a constant number of linearprogramming problems per facet of the projection in the absence of degeneracy. The ESP algorithm allows us to compute also projected geometric diameters of high-dimensional polytopes. A representation set of projected polytopes is presented to illustrate the methods adopted in this thesis.

Convergent Approaches for the Synthesis of the Anti-tumoral Peptide, Kahalalide F. Study of Orthogonal Protecting Groups

Kahalalide compounds are peptides that are isolated from a Hawaiian herbivorous marine species of mollusc, Elysia rufescens, and its diet, the green alga Bryopsis sp. Kahalalide F and its synthetic analogues are the most promising compounds of the Kahalalide family because they show anti-tumoral activity. Linear solid-phase syntheses of Kahalalide F have been reported. Here we describe several new improved synthetic routes based on convergent approaches with distinct orthogonal protection schemes for the preparation of Kahaladide analogues. These strategies allow a better control and characterization of the intermediates because more reactions are performed in solution. Five derivatives of Kahalalide F were synthesized using several convergent approaches.
