Toimintasuunnitelman laatiminen ohutlevytuotteita ja hitsauskokoonpanoja valmistavalle yritykselle

Tämän diplomityön tavoitteena oli luoda ohutlevytuotteita ja hitsauskokoonpanoja valmistavalle yritykselle kokonaisvaltainen toimintasuunnitelma ja esitellä erilaisia tuotantomalleja case-esimerkkien avulla. Työn aikana kartoitettiin yrityksennykytilannetta ja ongelmakohtia, pohdittiin nykyistä konekantaa ja löytyneitä pullonkauloja. Lisäksi suunniteltiin korjaustoimenpiteitä ja mitä tulisi tehdä, kun tulevaisuudessa yrityksen liikevaihto tulee kasvamaan ja yritystä tullaan laajentamaan. Pääpaino oli myös laskelmilla, joissa selvitettiinmahdollisten investointien tuntihintaa. Tuntihinnan avulla laadittiin taulukoita, joiden avulla ulosmyyntihinta on helppo määrittää. Tuntihinta kytkettiin sijoitetulle pääomalle haluttuun tuottoprosenttiin.

TEORES DE NUTRIENTES FOLIARES NO MARACUJAZEIRO-AMARELO ASSOCIADOS À ESTAÇÃO FENOLÓGICA, ADUBAÇÃO POTÁSSICA E LÂMINAS DE IRRIGAÇÃO

Conduziu-se um experimento em Campos dos Goytacazes-RJ, para avaliar o efeito da adubação potássica, de lâminas de irrigação e de épocas do ano nos teores de N, P, K, Ca, Mg, S, Zn, Fe, Cu, B, Cl, Mn e Na no maracujazeiro-amarelo (Passiflora edulis f. flavicarpa). Foram testadas, num Argissolo Amarelo distrófico, quatro doses de potássio (76; 307; 531 e 764 g planta-1 ano-1 de K), utilizando o cloreto de potássio, sob seis lâminas de irrigação (0; 25; 50; 75; 100 e 125% da ETo - Evapotranspiração de referência), num esquema fatorial 4 x 6. Os teores de nutrientes, na matéria seca foliar, relacionados com a máxima produtividade de frutos (43,5 t ha-1), variaram, nas diferentes épocas do ano, de 34,7 a 49,8 g kg-1 de N, 2,31 a 3,43 g kg-1 de P, 23,5 a 35,5 g kg-1 de K, 10,6 a 15,1 g kg-1 de Ca, 2,13 a 3,62 g kg-1 de Mg, 3,19 a 4,33 g kg-1 de S, 16,9 a 28,9 g kg-1 de Cl, 77 a 135 mg kg-1 de Fe, 50,1 a 91,4 mg kg-1 de Mn, 26,1 a 37,6 mg kg-1 de Zn, 4,53 a 95,4 mg kg-1 de Cu, 22,8 a 54,5 mg kg-1 de B e de 0,96 a 2,31 g kg-1 de Na. O adubo potássico elevou os teores de K e Cl e reduziu os de Mg, Mn, Zn e Na nas folhas do maracujazeiro. A irrigação afetou os teores de N, Cl e Na e não influenciou nos teores foliares dos demais nutrientes avaliados.

Analysis of a finite volume method for a cross-diffusion model in population dynamics

The main goal of this paper is to propose a convergent finite volume method for a reactionâeuro"diffusion system with cross-diffusion. First, we sketch an existence proof for a class of cross-diffusion systems. Then the standard two-point finite volume fluxes are used in combination with a nonlinear positivity-preserving approximation of the cross-diffusion coefficients. Existence and uniqueness of the approximate solution are addressed, and it is also shown that the scheme converges to the corresponding weak solution for the studied model. Furthermore, we provide a stability analysis to study pattern-formation phenomena, and we perform two-dimensional numerical examples which exhibit formation of nonuniform spatial patterns. From the simulations it is also found that experimental rates of convergence are slightly below second order. The convergence proof uses two ingredients of interest for various applications, namely the discrete Sobolev embedding inequalities with general boundary conditions and a space-time $L^1$ compactness argument that mimics the compactness lemma due to Kruzhkov. The proofs of these results are given in the Appendix.

Predictions of the MCMI-III personality disorders from NEO-PI-R domains and facets: Comparison between American and Spanish samples

Este estudio ex post facto analiza las relaciones entre las dimensiones y facetas del NEO-PI-R y los 14 trastornos de personalidad del MCMI-III en una muestra no clínica española (N = 674). Se exploran las diferencias y similitudes con los resul- tados de Dyce y O’Connor en una muestra americana con los mismos instrumentos. Como se esperaba, los análisis factoriales de facetas reteniendo cinco factores mostraron un modelo de relaciones muy similar entre ambas muestras, con un coeficiente de la congruencia total de 0,92, y coeficientes de congruencia de factor aceptables, salvo para el factor Apertura (0,68). En consonancia con las predicciones de Widiger y Widiger et al. los porcentajes de correlaciones significativas estaban alrededor de 60% en ambas muestras, y la mayoría coincidían. El análisis de regresión múltiple con dimensiones también reveló un gran parecido entre los resultados americanos y españoles, Neuroticismo fue el predictor más relacionado con los trastornos de personalidad. Se encontraron diferencias en las regresiones por facetas, aunque la varianza explicada fue prácticamente la misma que en las dimensiones. Se discute la validez transcultural y el valor predictivo del NEO-PI-R sobre los trastornos de personalidad del MCMI-III, junto con las ventajas relativas de las facetas sobre las dimensiones.

Prevalence and management of cardiovascular risk factors in Portuguese living in Portugal and Portuguese who migrated to Switzerland.

BACKGROUND: Information regarding the health status of migrants compared to subjects who remain in the country of origin is scarce. We compared the levels and management of the main cardiovascular risk factors between Portuguese living in Porto (Portugal) and Portuguese migrants living in Lausanne (Switzerland). METHODS: Cross-sectional studies conducted in Porto (EPIPorto, 1999 to 2003, n = 1150) and Lausanne (CoLaus, 2003 to 2006, n = 388) among subjects aged 35-65 years. Educational level, medical history and time since migration were collected using structured questionnaires. Body mass index, blood pressure, cholesterol and glucose levels were measured using standardized procedures. RESULTS: Portuguese living in Lausanne were younger, more frequently male and had lower education than Portuguese living in Porto. After multivariate adjustment using Poisson regression, no differences were found between Portuguese living in Porto or in Lausanne: prevalence rate ratio (PRR) and (95% confidence interval) for Portuguese living in Lausanne relative to Portuguese living in Porto: 0.92 (0.71 - 1.18) for current smoking; 0.78 (0.59 - 1.04) for obesity; 0.81 (0.62 - 1.05) for abdominal obesity; 0.82 (0.64 - 1.06) for hypertension; 0.88 (0.75 - 1.04) for hypercholesterolemia and 0.92 (0.49 - 1.73) for diabetes. Treatment and control rates for hypercholesterolemia were higher among Portuguese living in Lausanne: PRR = 1.91 (1.15 - 3.19) and 3.98 (1.59 - 9.99) for treatment and control, respectively. Conversely, no differences were found regarding hypertension treatment and control rates: PRR = 0.98 (0.66 - 1.46) and 0.97 (0.49 - 1.91), respectively, and for treatment rates of diabetes: PRR = 1.51 (0.70 - 3.25). CONCLUSIONS: Portuguese living in Lausanne, Switzerland, present a similar cardiovascular risk profile but tend to be better managed regarding hypercholesterolemia than Portuguese living in Porto, Portugal.

Métamorphoses identitaires en situation de mobilité

Identity metamorphoses in a context of mobility This study has its roots in the current upsurge in student mobility and in the scientific debates about the concepts of identity and intercultural communication. Based on a corpus of interviews with French Erasmus students in Finland, the study blends in theories of postmodern identity, intercultural hermeneutics and discourse analysis to examine how the students construct themselves and diverse ‘othernesses’ (included theirs) when they talk about their experiences. The use of the French pronoun on, pronoun switches, and virtual voices (ex: I said to myself...) allowed to pinpoint the students’ unstable identity metamorphoses in their discourses: integration of liquid and solid selves, infidelity in identification with the French but also with Erasmus ‘tribes’, and games of identity. Though the exchange experience appears as interesting for the students, the results show that many and varied misconceptions about identity, culture, intercultural communication, language use, and strangeness lead the students to evaluate their experiences negatively. The implication of the study is that students should be prepared for their time abroad, not so much in terms of ‘grammars of culture’ (e.g. ‘Finns behave in such and such ways’, ‘the French are...’), but through the development of competences to analyse the identity metamorphoses that take place in intercultural encounters and prevent people from meeting each other as diverse individuals. This could make study abroad one of the best training periods for postmodernity and globalization.

A qualitative study of adolescents with medically unexplained symptoms and their parents. Part 1: Experiences and impact on daily life.

Medically unexplained symptoms (MUS) are common among adolescents and are frequently encountered in primary care. Our aim was to explore how these adolescents and their parents experience the condition and its impact on their daily lives and to provide recommendations for health professionals. Using a qualitative approach, six focus groups and two individual interviews were conducted. These involved a total of ten adolescents with different types of MUS and sixteen parents. The respondents were recruited in a university hospital in Switzerland. A thematic analysis was conducted according to the Grounded Theory. The analysis of the data highlighted four core themes: disbelief, being different, concealing symptoms, and priority to adolescent's health. Transcending these themes was a core issue regarding the discrepancy between the strategies that adolescents and their parents use to cope with the symptoms. Health professionals should be made aware of the emotional needs of these patients and their families.

Qualitative, quantitative and temporal study of cutting agents for cocaine and heroin over 9 years

Forensic laboratories mainly focus on the qualification and the quantitation of the illicit drug under analysis as both aspects are used for judiciary purposes. Therefore, information related to cutting agents (adulterants and diluents) detected in illicit drugs is limited in the forensic literature. This article discusses the type and frequency of adulterants and diluents detected in more than 6000 cocaine specimens and 3000 heroin specimens, confiscated in western Switzerland from 2006 to 2014. The results show a homogeneous and quite unchanging adulteration for heroin, while for cocaine it could be characterised as heterogeneous and relatively dynamic. Furthermore, the results indicate that dilution affects more cocaine than heroin. Therefore, the results provided by this study tend to reveal differences between the respective structures of production or distribution of cocaine and heroin. This research seeks to promote the systematic analysis of cutting agents by forensic laboratories. Collecting and processing data related to the presence of cutting agents in illicit drug specimens produces relevant information to understand and to compare the structure of illicit drug markets.

Diagnostic and prognostic value of antibodies against chimeric fibrin/filaggrin citrullinated synthetic peptides in rheumatoid arthritis

Introduction: Evidence suggests that citrullinated fibrin(ogen) may be a potential in vivo target of anticitrullinated protein/peptide antibodies (ACPA) in rheumatoid arthritis (RA). We compared the diagnostic yield of three enzyme-linked immunosorbent assay (ELISA) tests by using chimeric fibrin/filaggrin citrullinated synthetic peptides (CFFCP1, CFFCP2, CFFCP3) with a commercial CCP2-based test in RA and analyzed their prognostic values in early RA. Methods: Samples from 307 blood donors and patients with RA (322), psoriatic arthritis (133), systemic lupus erythematosus (119), and hepatitis C infection (84) were assayed by using CFFCP- and CCP2-based tests. Autoantibodies also were analyzed at baseline and during a 2-year follow-up in 98 early RA patients to determine their prognostic value. Results: With cutoffs giving 98% specificity for RA versus blood donors, the sensitivity was 72.1% for CFFCP1, 78.0% for CFFCP2, 71.4% for CFFCP3, and 73.9% for CCP2, with positive predictive values greater than 97% in all cases. CFFCP sensitivity in RA increased to 80.4% without losing specificity when positivity was considered as any positive anti-CFFCP status. Specificity of the three CFFCP tests versus other rheumatic populations was high (> 90%) and similar to those for the CCP2. In early RA, CFFCP1 best identified patients with a poor radiographic outcome. Radiographic progression was faster in the small subgroup of CCP2-negative and CFFCP1-positive patients than in those negative for both autoantibodies. CFFCP antibodies decreased after 1 year, but without any correlation with changes in disease activity. Conclusions: CFFCP-based assays are highly sensitive and specific for RA. Early RA patients with anti-CFFCP1 antibodies, including CCP2-negative patients, show greater radiographic progression.

Overspeed HIIT in Lower-Body Positive Pressure Treadmill Improves Running Performance.

PURPOSE: Optimal high-intensity interval training (HIIT) regimens for running performance are unknown, although most protocols result in some benefit to key performance factors (running economy (RE), anaerobic threshold (AT), or maximal oxygen uptake (V˙O2max)). Lower-body positive pressure (LBPP) treadmills offer the unique possibility to partially unload runners and reach supramaximal speeds. We studied the use of LBPP to test an overspeed HIIT protocol in trained runners. METHODS: Eleven trained runners (35 ± 8 yr, V˙O2max, 55.7 ± 6.4 mL·kg·min) were randomized to an LBPP (n = 6) or a regular treadmill (CON, n = 5), eight sessions over 4 wk of HIIT program. Four to five intervals were run at 100% of velocity at V˙O2max (vV˙O2max) during 60% of time to exhaustion at vV˙O2max (Tlim) with a 1:1 work:recovery ratio. Performance outcomes were 2-mile track time trial, V˙O2max, vV˙O2max, vAT, Tlim, and RE. LBPP sessions were carried out at 90% body weight. RESULTS: Group-time effects were present for vV˙O2max (CON, 17.5 vs. 18.3, P = 0.03; LBPP, 19.7 vs. 22.3 km·h; P < 0.001) and Tlim (CON, 307.0 vs. 404.4 s, P = 0.28; LBPP, 444.5 vs. 855.5, P < 0.001). Simple main effects for time were present for field performance (CON, -18; LBPP, -25 s; P = 0.002), V˙O2max (CON, 57.6 vs. 59.6; LBPP, 54.1 vs. 55.1 mL·kg·min; P = 0.04) and submaximal HR (157.7 vs. 154.3 and 151.4 vs. 148.5 bpm; P = 0.002). RE was unchanged. CONCLUSIONS: A 4-wk HIIT protocol at 100% vV˙O2max improves field performance, vV˙O2max, V˙O2max and submaximal HR in trained runners. Improvements are similar if intervals are run on a regular treadmill or at higher speeds on a LPBB treadmill with 10% body weight reduction. LBPP could provide an alternative for taxing HIIT sessions.
