La presente memoria de experiencia profesional tiene como objetivo comprobar que proteger la calidad e integridad del producto es lo más importante para la compañía, ya que depende por completo del cliente y este a su vez se debe asegurar la correcta rotación y frescura de los productos terminados para evitar que alcancen o rebasen su estándar de edad en cualquier etapa de la cadena de valor, desde su ingreso al Centro de Distribución (CEDIS) y finalmente a manos de los clientes.
El puesto de Total Product Management o Manejo Total del Producto (TPM) surgió de la necesidad de contar con un sistema de mejora continua para la administración de todos los elementos que conforman a la compañía Jugos del Valle S.A. de C.V. (JDV), puesto que fue implementado por el grupo The Coca-Cola company gracias a ello, se contribuye la participación en la elaboración de los productos dentro de los estándares de calidad, inocuidad y seguridad que el cliente requiere, de igual forma cumplir al 100% los procesos que lo conllevan y que de este modo se tenga una operación controlada. Al responsable del puesto de TPM, se le conoce como analista TPM ya que es el encargado de aplicar los procesos para todas las etapas de la cadena de valor, es decir desde que se elabora el producto, pasando por almacén de planta, transporte, centros de distribución, rutas, distribuidores, detallistas y por último llegando a manos del cliente final.
Las condiciones de manejo para los productos que la compañía requiere dependen del tiempo de permanencia y la temperatura en toda la cadena de valor, desde su almacenamiento, distribución, comercialización y exhibición de los productos. Se tiene que garantizar al consumidor que los productos que se les están vendiendo son recibidos con el grado de frescura y calidad requerida, cabe mencionar que dentro de las bondades adicionales a mencionar podemos destacar el aumento efectivo para la mejora a la rotación y el incremento de la calidad logrado en los procesos productivos dirigidos al mercado de bebidas.

El tiempo se ha convertido en una de las preocupaciones diarias de los adultos y las posibilidades de qué hacer con él, si el día tuviera más horas, en un sueño inalcanzable. La vida agitada que conlleva tener una rutina diaria entre el trabajo, los estudios y el hogar, deja al ser humano en un bucle interminable de acciones que solo logran estresarlos más. Entonces, ¿cómo transformar esas vidas que normalmente se encuentran reactivas al cambio? El camino al autoconocimiento y al equilibrio personal solo son posibles a través del movimiento, relajación y una alimentación consciente. Actualmente, las empresas de nuestro país que ofrecen opciones para llevar una vida saludable y activa se enfocan en actividades tradicionales dictadas en un local físico con ejercicios estándares. La presente investigación, tiene como objetivo descubrir las preferencias de un entrenamiento que integre el área física, mental y alimentación consciente desde una plataforma online para que los usuarios accedan a los talleres desde donde se encuentren y cuando quieran. Con esta finalidad, se diseñó una metodología mixta, a través de la técnica cuantitativa (encuesta y PMV) y cualitativa (entrevista semiestructurada) a un público limeño entre 25 y 35 años, con la finalidad de validar la viabilidad del proyecto. Los resultados arrojaron que el proyecto responde a la demanda de los talleres online propuestos; pero también nos deja el desafío constante de agregar otros talleres de acuerdo a la tendencia y preferencia, bajo la misma filosofía del proyecto.Time has become a daily concern for adults and the possibilities of what to do with it –if the day had more hours– are an unreachable dream. The hurried lifestyle that comes with having a daily routine between work, studies and home, leaves the human being in an endless loop of events that only make them more stressed. So how do we transform those lives that normally are reactive to change? The path to self-knowledge and personal balance is only possible through movement, relaxation and mindful eating. Nowadays, the companies in our country that offer options to lead a healthy and active life, focus on traditional activities located in a establishment with standard exercises. This research aims to discover the preferences of a training that integrates the physical, mental and mindful eating area from an online platform so that users can access the workshops wherever they are and whenever they want. For this purpose, it was designed a mixed methodology, through the quantitative technique (survey and MVP) and qualitative (semi-structured interview) to an audience of Lima residents between 25 and 35 years old, in order to validate the viability of the project. The results showed that the project responds to the demand of the proposed digital workshops; but it also leaves us the constant challenge of adding other workshops according to the tren and preference in order to the same philosophy of the project

Resumo: Pacientes com neoplasias mamárias sofrem de dor tanto pela própria neoplasia quanto pelo seu tratamento cirúrgico, a mastectomia. A mastectomia é um procedimento cirúrgico bastante agressivo que frequentemente causa sensibilização central devido a estímulos repetidos aos nociceptores periféricos, levando, consequentemente, à dor neuropática. Tendo em vista maior conforto e qualidade na cirurgia e na recuperação destes pacientes, faz-se necessário o uso de um protocolo analgésico adequado ao nível de dor ao qual o paciente é submetido, considerando tanto a doença quanto o procedimento. Os opioides apresentam-se como uma boa alternativa, uma vez que apresentam potente atividade analgésica e estabilidade hemodinâmica durante a manutenção da anestesia, além de diminuírem a dose necessária de propofol para a manutenção. São escassos os estudos que envolvem a utilização de anestesia intravenosa total com propofol associada à infusão contínua de opioides bem como outras técnicas analgésicas para mastectomia em cães. Por isso, são necessários estudos que avaliem a eficácia analgésica destes opioides tanto no transoperatório como no pós-operatório e a sua influência no requerimento de propofol para a manutenção do plano anestésico, proporcionando alívio da dor aos animais e redução do volume de anestésico utilizado durante a cirurgia. Os opioides apresentam-se como uma boa alternativa, uma vez que apresentam potente atividade analgésica e estabilidade hemodinâmica durante a manutenção da anestesia, além de diminuírem a dose necessária de propofol para a manutenção. A pesquisa foi dividida em 2 etapas. A primeira avaliou e comparou a associação de fentanil, alfentanil, sufentanil e remifentanil com propofol em mastectomia unilateral em cães. A segunda avaliou e comparou a associação de fentanil, cetamina e lidocaína ou a peridural alta com ropivacaína e morfina com propofol em mastectomia unilateral em cães. Quando comparado com a infusão de fentanil, as infusões de sufentanil e alfentanil reduziram o requerimento de propofol. Sufentanil, alfentanil e remifentanil permitiram reduzir o requerimento de propofol precocemente, indicando a possibilidade da não realização de um bolus inicial. O remifentanil esteve associado a menores escores de dor durante as primeiras 24 horas após a cirurgia quando comparado ao fentanil e ao alfentanil. Palavras-chave: TIVA, dor, mastectomia, cão, analgesia.
Abstract: Patients with breast cancer suffer from pain originated from neoplasia and for their surgical treatment, mastectomy. Mastectomy is a very aggressive surgical procedure that often causes central sensitization due to repeated stimuli to the peripheral nociceptors, leading consequently to neuropathic pain. Looking for comfort and quality during surgery and recovery of these patients, it is necessary to use an appropriate analgesic protocol considering the level of the pain which the patient is subjected, considering both disease and the procedure. Opioids are presented as a good alternative, since they have potent analgesic activity and hemodynamic stability during maintenance of anesthesia as well as they decrease the required dose of propofol for maintenance. There are few studies involving the use of total intravenous anesthesia with propofol associated with continuous infusion of opioid analgesics, as well as other analgesic techniques for mastectomy in dogs. Therefore, studies are needed to evaluate the analgesic effectiveness of opioids both during surgery and in the postoperative period and its influence on propofol requirement for the maintenance of anesthesia, providing pain relief and reducing the volume of anesthetic used during surgery. Opioids are presented as a good alternative, since they have potent analgesic activity and hemodynamic stability during maintenance of anesthesia as well as they decrease the required dose of propofol for maintenance. The research was divided into two stages. The first evaluated and compared the association of fentanyl, alfentanil, sufentanil and remifentanil with propofol for unilateral mastectomy in dogs. The second evaluated and compared the association of fentanyl, ketamine and lidocaine or high ropivacaine and morphine epidural with propofol for unilateral mastectomy in dogs. When compared with fentanyl infusion, the infusion of sufentanil and alfentanil reduced propofol application. Sufentanil, alfentanil and remifentanil have reduced the propofol requirement earlier, indicating the possibility of avoiding a loading dose. The remifentanil was associated with lower pain scores during the first 24 hours after surgery when compared to fentanyl and alfentanil. No difference was observed in the propofol requirement using cranial morphine ropivacaine epidural analgesia or continuous intravenous infusion of remifentanil, ketamine and lidocaine in dogs underwent mastectomy. However, the anesthetic recovery was faster and the application of analgesic rescues was lower when used intravenous technique. Keywords: TIVA, pain, mastectomy, dog, analgesy,

Näringsämnena har en stor betydelse för sötvattnets organismer och ekosystem, varav de vanligaste näringsämnena som även är de viktigaste är fosfor (P), kväve (N) samt kol (C). Näringsämnena kommer inte enbart till sjön via nedfall och fixering utav mycket av näringsämnena kommer in till en sjö via vattendrag som till exempel älvar där Klarälven räknas in som en av Sveriges älvar. Syftet med denna studie är att ta fram en tidstrend mellan åren 1996 och 2013 för näringsämnena totalfosfor, totalkväve och TOC (totalt organiskt kol) för tio lokaler i norra Vänern för att kunna avgöra om de är lika, om det är något år som sticker ut, om det finns någon påverkan av Klarälven för de sjölokaler som tas upp och se om värdena av näringshalter kan kopplas till fiskförekomsten. Data samlades in och plottades i diagram för att kunna jämföras med varandra. Med sjölokalernas näringsvärde gjordes korrelationstester med älvarnas näringshalter för att se samband och därefter gjorde korrelation med sjölokalernas näringsvärden med andelen skördad fisk i samma lokaler. Resultatet visade att Ölman och Ölmeviken är väldigt eutrofierade medan resterande lokaler hade oligotrofa eller mesotrofa vatten och översvämningen i Karlstad 2000 visade avtryck i tidstrenden. Klarälvens påverkan på sjölokalerna visade sig inte vara så stor utan samband upptäcktes enbart mellan Kaplansådran och Hammarösjön för totalkvävet och för TOC upptäcktes samband mellan Hammarösjön och Sätterholmsfjärden med Kaplansådran.The nutrient is very important for fresh water organisms and ecosystems, of which the most common nutrients also is the most important is phosphorus (P), nitrogen (N) and carbon (C). The nutrients will not only come into a lake through deposition and fixation, much of the nutrients is coming into the lake through rivers such as Klarälven in Sweden. The purpose of this study is to develop a temporal and spatial trend during 1996-2013 for the nutrients total phosphorus, total nitrogen and TOC (total organic carbon) for ten premises in northern Lake Vänern to determine if they are equal, if it is a year that stands out from the rest, if there is any influence of Klarälven for the lake premises and see if the values of the nutrient concentrations can be linked to the presence of fish. Data were collected and plotted in graphs to be compared with each other. Correlation test was made with the lake premises nutrient values and rivers nutrient value to see if there was a connection between the locations, same correlation was also made between the lake premises nutrient values and the percentage of fish harvested in the same premises. The result showed that Ölman and Ölmeviken is very eutrophic, while the remaining premises hade oligotrophic or mesotrophic water and the flooding in Karlstad in 2000 showed imprint in the time trend. The impact of Klarälven on the lake premises proved to not be so great, but the context was detected only between Kaplansådran and Hammarösjön for the total nitrogen and correlation for TOC between Hammarösjön and Sätterholmsfjärden with Kaplansådran was also detected.

Full textAbstract:
Uncertainties in aerosol radiative forcings, especially those associated with clouds, contribute to a large extent to uncertainties in the total anthropogenic forcing. The interaction of aerosols with clouds and radiation introduces feedbacks which can affect the rate of precipitation
formation. In former assessments of aerosol radiative forcings, these effects have not been quantified. Also, with global aerosol-climate models simulating interactively aerosols and cloud microphysical properties, a quantification of the aerosol forcings in the traditional way is difficult to
define properly. Here we argue that fast feedbacks should be included because they act quickly compared with the time scale of global warming. We show that for different forcing agents (aerosols and greenhouse gases) the radiative forcings as traditionally defined agree rather well with estimates from a method, here referred to as radiative flux perturbations
(RFP), that takes these fast feedbacks and interactions into account. Based on our results, we recommend RFP as a valid option to compare different forcing agents, and to compare the effects of particular forcing agents in different models.

Full textAbstract:
In most industrial situations chemical processes operate within "Total Sites", where they are serviced and linked through a central utility system. Established procedures for heat and power integration work well for optimising each process in isolation. However, greater benefits in terms of energy and capital can be obtained by looking at the entire site. Total site integration addresses the task of optimising each process and the utility system in the context of the overall site. Total site integration has only received limited attention. Various attempts have been made to explore the complex interactions between the processes. However the trade-offs between fuel consumption and co-generation have not yet been established. Therefore, design solutions are mainly derived based on intuition. Since a systematic methodology to address the problem does not actually exist, many iterations may be involved in deriving good solutions and attractive design options can be missed. This thesis provides analytical tools that help understand the interactions between site fuel, heat recovery and co-generation. Capital implications are also addressed. Based on these analytical tools, procedures are developed to tackle total site integration problems including retrofits, site expansions and grassroots, in a systematic way. The procedures do not aim to generate a single optimum solution. Developed within the framework of Pinch Analysis, they are based on physical insights and can help engineers obtain good practical solutions. They can be used to scope and screen major design decisions during the conceptual design stage. The concepts developed in this thesis to address process integration in the context of total sites, do not in any way invalidate the existing Pinch Analysis principles for single process optimisation. Rather, being totally compatible to them, they lift Pinch Analysis onto a higher level of perception.

Todas as operações produtivas, não importam quão bem gerenciadas sejam, podem ser melhoradas. Este trabalho trata do aumento da produtividade industrial através da redução das perdas operacionais associadas aos períodos onde os trabalhadores e os equipamentos não estão sendo utilizados produtivamente. O método apresentado é o programa de melhoria de resultados industriais - PMRI, com o objetivo de promoção da manutenção produtiva total - MPT. O PMRI propõe reduzir as perdas nos sistemas produtivos em que operadores de equipamentos participem encontrando causa das perdas operacionais, através da manutenção autônoma de trabalhos em pequenos grupos e atividades integradas de manutenção preventiva e preditiva. No método PMRI é essencial reduzir todas as formas de perdas que não agrega valor ao processo, mas custo, como as anomalias do equipamento, que são as quebras, falhas, qualquer tipo de manutenção corretiva, defeitos em produtos, refugos, retrabalho, paradas não planejadas de qualquer natureza. Estas perdas devem ser vistas como oportunidade de melhoria da organização empresarial, através do comprometimento da equipe de produção e manutenção, para garantir a melhoria contínua do desempenho do equipamento na atividade produtiva agregando satisfação ao cliente e lucratividade para a empresa. O PMRI foi testado em equipamentos críticos de uma linha de empacotamento de biscoitos em uma empresa alimentícia de grande porte, que possibilitou uma visão prática do método, agregando melhorias reais no processo produtivo da empresa

Full textAbstract:
The total character of a finite group G is the sum of the irreducible characters of G. When the total character of a finite group can be written as a monic polynomial with integer coefficients in an irreducible character of G, we say that G is a total character group. In this thesis we examine the total character of the dicyclic group of order 4n, the non-abelian groups of order p^3, and the symmetric group on n elements for all n ≥ 1. The dicyclic group of order 4n is a total character group precisely when n is congruent to 2 or 3 mod 4, and the associated polynomial is a sum of Chebyshev polynomials of the second kind. The irreducible characters paired with these polynomials are exactly the faithful characters of the dicyclic group. In contrast, the non-abelian groups of order p^3 and the symmetric group on n elements with n ≥ 4 are not total character groups. Finally, we examine the special case when G is a total character group and the polynomial is of degree 2. In this case, we say that G is a quadratic total character group. We classify groups which are both quadratic total character groups and p-groups.

Full textAbstract:
Un dels interessos de la societat actual és conèixer l’impacte de l’activitat humana en el medi ambient, especialment quan aquesta fa ús de materials radioactius. En aquest sentit, a més dels episodis de contaminació radioactiva, és important conèixer els nivells d’exposició a les fonts naturals de radioactivitat i l’efecte de les activitats humanes sobre la redistribució dels materials amb radioactivitat natural (NORM, Natural Ocurring Radioactive Materials), ja que aquests es troben àmpliament distribuïts i tenen un efecte global sobre la població molt superior al de la indústria nuclear. Aquesta necessitat requereix disposar de metodologia senzilla i fàcilment aplicable a matrius diverses, que a més proporcioni resultats fiables en un temps curt.
El contingut radioactiu pot ser estimat de forma ràpida a partir dels índexs d’activitat alfa total i beta total, que informen de manera global sobre la presència de radionúclids en una mostra. El seu coneixement permet prendre decisions sobre la viabilitat d’un ús o una aplicació concreta, així com de la necessitat de fer determinacions de radionúclids específics, que suposa anàlisis més llargues i costoses. L’Organització Mundial de la Salut estableix valors paramètrics per a aquests índexs en les seves directrius sobre la qualitat de l’aigua de consum i molts països estableixen controls basats en aquests índexs per al control radiològic de l’aigua per al consum humà.
La determinació d’índexs d’activitat s’ha realitzat tradicionalment mitjançant detectors proporcionals de flux continu de gas o detectors d’escintil•lació sòlida. En els darrers anys, la tècnica d’escintil•lació líquida ha esdevingut una alternativa a les tècniques clàssiques, doncs permet la determinació simultània dels dos paràmetres a partir de quantitats de mostra petites, procediments senzills i temps de mesura curts. La mesura d’índexs d’activitat per escintil•lació líquida depèn de diversos factors, alguns dels quals poden ser controlats fàcilment (tipus de vial, relació mostra/escintil•lador, paràmetre de discriminació), mentre d’altres resulten més difícils de controlar (energies d’emissió, matriu).
Donat l’impacte sobre la societat i l’economia que tenen els resultats analítics, és necessari dur a terme activitats per a l’assegurament de la qualitat del treball realitzat. En aquest sentit, la implantació de sistemes de gestió de la qualitat als laboratoris d’acord amb normes internacionals com la UNE-EN ISO/IEC 17025:2005 garanteix que una entitat satisfarà els requeriments de qualitat necessaris pel que fa a la gestió i formació del personal, l’adequació de les condicions ambientals del laboratori, la seguretat, l’emmagatzematge, conservació i identificació de les mostres, la conservació dels registres, el manteniment i calibratge dels instruments, i la utilització de mètodes documentats adequadament i tècnicament validats.
En aquesta tesi doctoral s’han estudiat àmpliament els paràmetres que afecten la mesura per escintil•lació i s’ha desenvolupat metodologia analítica per a la determinació de l’activitat alfa total i beta total en aigües continentals i de consum per escintil•lació líquida com a mètode de garbellat. A partir d’aquests estudis s’ha treballat per fer aquestes determinacions en matrius més complexes. Així la metodologia s’ha validat també per a la determinació d’aquests paràmetres en aigua de mar i s’han realitzat estudis per a la seva determinació en sòls.
Un segon aspecte en què s’ha treballat en aquesta tesi doctoral ha estat la gestió de la qualitat al laboratori analític en el marc de la norma UNE-EN ISO/IEC 17025:2005. En aquest sentit, el treball presentat descriu la implantació i manteniment d’un sistema de garantia de qualitat al Laboratori de Radiologia Ambiental per a l’acreditació de les activitats que s’hi realitzen, incloent la metodologia desenvolupada per a la determinació d’índexs d’activitat alfa total i beta total en mostres d’aigua."Determination of gross alpha and gross beta activities by liquid scintillation" Modern societies are concerned about the levels of exposure to natural sources of radioactivity and the effect that human activities have on the redistribution of naturally occurring radioactive materials (NORM), since these have a global effect on the population much higher than that of the nuclear industry. The radioactive content can be estimated from two parameters: gross alpha and gross beta activities, which give global information about the presence of alpha and beta emitters in a sample, in order to decide about the viability of a use or application. These values can also be helpful to decide whether determinations of specific radionuclides, which require longer and more expensive procedures, are necessary. This is the case of the World Health Organization guidelines on the quality of drinking water, which are the basis to establish the radiological control of water for human consumption in many countries. However, for gross alpha and gross beta to be useful tools in environmental radioactivity control, it is necessary to dispose of analytical methods which can be easily applicable to different matrices and provide reliable results in a short time. In this thesis, the parameters affecting the simultaneous measurement of gross alpha and gross beta activities using liquid scintillation were studied and analytical methods validated for such determinations in environmental samples, from waters of different kinds (surface, underground and human consumption) to more complex matrices such as marine waters and soils. Given the impact that analytical results produce on society and economy, it is necessary to carry out activities to ensure the quality of the results produced by analytical laboratories. A second aspect the thesis deals with is quality management at the analytical laboratory following the norm UNE-EN ISO/IEC 17025:2005. A Quality Management System was implemented in the Environmental Radiology Laboratory for the accreditation of the assays carried out, including the method for the determination of gross alpha and gross beta activities in water samples previously validated.

Jones, Amber Spackman. "Estimating Total Phosphorus and Total Suspended Solids Loads from High Frequency Data." DigitalCommons@USU, 2008. https://digitalcommons.usu.edu/etd/205.
Full textAbstract:
Frequently measured turbidity was examined as a surrogate for total phosphorus (TP) and total suspended solids (TSS) loads at two locations in the Little Bear River, Utah, USA. Using regression techniques, equations were developed for TP and TSS as functions of turbidity. The equations accounted for censored data, and additional explanatory variables to represent hydrological conditions were considered for inclusion in the equations. By using the resulting surrogate relationships with high frequency turbidity measurements, high frequency estimates of TP and TSS concentrations were calculated. To examine the effect of sampling frequency, reference loads were determined from the concentration records for two water years. The concentration records were artificially decimated to represent various frequencies of manual grab sampling from which annual loads were calculated and compared to the reference loads.

Full textAbstract:
Low back pain consumes a large part of the community’s resources dedicated to health care and sick leave. Back disorders also negatively affect the individual leading to pain suffering, decreased quality-of-life and disability. Chronic low back pain (CLBP) due to degenerative disc disease (DDD) is today often treated with fusion when conservative treatment has failed and symptoms are severe. This treatment is as successful as arthroplasty is for hip arthritis in restoring the patient’s quality of life and reducing disability. Even so, there are some problems with this treatment, one of these being recurrent CLBP from an adjacent segment (ASD) after primarily successful surgery. This has led to the development of alternative surgical treatments and devices that maintain or restore mobility, in order to reduce the risk for ASD. Of these new devices, the most frequently used are the disc prostheses used in Total Disc Replacement (TDR). This thesis is based on four studies comparing total disc replacement with posterior fusion. The studies are all based on a material of 152 patients with DDD in one or two segments, aged 20-55 years that were randomly treated with either posterior fusion or TDR. The first study concerned clinical outcome and complications. Follow-up was 100% at both one and two years. It revealed that both treatment groups had a clear benefit from treatment and that patients with TDR were better in almost all outcome scores at one-year follow-up. Fusion patients continued to improve during the second year. At two-year follow-up there was a remaining difference in favour of TDR for back pain. 73% in the TDR group and 63% in the fusion group were much better or totally pain-free (n.s.), while twice as many patients in the TDR group were totally pain free (30%) compared to the fusion group (15%). Time of surgery and total time in hospital were shorter in the TDR group. There was no difference in complications and reoperations, except that seventeen of the patients in the fusion group were re-operated for removal of their implants. The second study concerned sex life and sexual function. TDR is performed via an anterior approach, an approach that has been used for a long time for various procedures on the lumbar spine. A frequent complication reported in males when this approach is used is persistent retrograde ejaculation. The TDR group in this material was operated via an extra-peritoneal approach to the retroperitoneal space, and there were no cases of persistent retrograde ejaculation. There was a surprisingly high frequency of men in the fusion group reporting deterioration in ability to have an orgasm postoperatively. Preoperative sex life was severely hampered in the majority of patients in the entire material, but sex life underwent a marked improvement in both treatment groups by the two-year follow-up that correlated with reduction in back pain. The third study was on mobility in the lumbar spinal segments, where X-rays were taken in full extension and flexion prior to surgery and at two-year follow-up. Analysis of the films showed that 78% of the patients in the fusion group reached the surgical goal (non-mobility) and that 89% of the TDR patients maintained mobility. Preoperative disc height was lower than in a normative database in both groups, and remained lower in the fusion group, while it became higher in the TDR group. Mobility in the operated segment increased in the TDR group postoperatively. Mobility at the rest of the lumbar spine increased in both treatment groups. Mobility in adjacent segments was within the norm postoperatively, but slightly larger in the fusion group. In the fourth study the health economics of TDR vs Fusion was analysed. The hospital costs for the procedure were higher for patients in the fusion group compared to the TDR group, and the TDR patients were on sick-leave two months less. In all, these studies showed that the results in the TDR group were as good as in the fusion group. Patients are more likely to be totally pain-free when treated with TDR compared to fusion. Treatment with this new procedure seems justified in selected patients at least in the short-term perspective. Long-term follow-up is underway and results will be published in due course.

This thesis describes the total synthesis of streptonigrone. The centerpiece of our route to the target molecule is a facile one-pot construction of 3-alkylpyridones developed in our laboratory. The quinoline segment of the target molecule, prepared through a Conrad-Limpach synthesis, was condensed with 2-benzyloxy-3,4-dimethoxybenzaldehyde to afford a chalcone intermediate suitable for our pyridine-forming reaction. The assembly of the central 3-methylpyridone ring of the natural product was then accomplished through the merger of the chalcone with 2-cyanopropanamide. Functionalization of the pyridone was then completed through an anionic sequence.Science, Faculty of

Full textAbstract:
Hyperforin is the component of the medicinal herb St. John's Wort (Hypericum perforatum) responsible for its antidepressant activity. It works by blocking the reuptake of a variety of neurotransmitters through a unique mechanism of action and may be a critical lead for the treatment of depression and possibly other human diseases. However, the therapeutic potential of hyperforin is severely handicapped by its poor water solubility, facile oxidative degradation, and potent activation of pregnane X receptor, leading to increased expression of many genes involved in xenobiotic metabolism. Access to a wide variety of hyperforin analogs is critical for mitigating these shortcomings while maintaining therapeutic activity. While limited semisynthetic manipulation of isolated hyperforin is feasible, total synthesis is the only possible means of obtaining diverse hyperforin analogs.Chemistry and Chemical Biology

This thesis studies the alternating sum of cohomology groups of a Springer fiber (in characteristic 0), called a total Springer representation, as a representation of both the Weyl group and the stabilizer of the corresponding nilpotent element. For classical types, we present explicit formulas for the decomposition of total Springer representations into irreducible ones of the corresponding Weyl group using Kostka-Foulkes polynomials. Also, the character value at any element contained in the maximal parabolic subgroup(s) of type A is explicitly given in terms of Green polynomials. As a result, closed formulas for the Euler characteristic of Springer fibers are deduced. Our proof relies on analysis of geometry of Springer fibers and combinatorics of symmetric functions. Moreover, we provide formulas for the character value of a total Springer representation at any element in the stabilizer of the corresponding nilpotent element. For exceptional types, the character values of total Springer representations are completely known. Here, we only describe the decomposition of such representations into irreducible ones of stabilizers of corresponding nilpotent elements.

Mestrado em FinançasA TOTAL S.A. ("TOTAL") é uma das maiores empresas da indústria de exploração de Petróleo e Gás Natural, com operações à escala mundial e um modelo operativo integrado, que abrange toda a cadeia de valor da indústria - a TOTAL é a 4ª maior empresa cotada desta indústria a nível mundial, com um ativo de $224 biliões e uma capitalização bolsista de $121,8 biliões. A TOTAL tem uma recomendação de investimento de "COMPRA", com um preço alvo de $59,3/acção no final de 2020, com uma valorização potencial de 31% face ao preço de fecho de $45.3, em 30 de Agosto de 2019, mas com risco elevado. A atual subvalorização da TOTAL deve-se essencialmente a i) expectativas pessimistas do desempenho económico mundial, ii) exposição do preço das matérias-primas, iii) instabilidade geopolítica e iv) à incerteza associada à tendência de transição energética. Relativamente às tendências futuras da indústria, a TOTAL tem o seu foco estratégico nos desafios da sustentabilidade ambiental e nas alterações climáticas. É disto exemplo o foco no crescimento do segmento de negócio ligado às energias renováveis, com um crescimento esperado de 14,5 pontos percentuais no peso das vendas, entre 2018 e 2023. Adicionalmente, a sólida posição financeira da TOTAL e o compromisso com a política de retorno para os accionistas, credibiliza a expectativa de crescimento dos dividendos de +10% entre 2018 e 2020, bem como o programa de recompra de acções de $5 biliões no mesmo período.
TOTAL S.A. ("TOTAL") is a major Oil & Gas player, that operates worldwide with an integrated operating model, including the exploration and production of oil and natural gas, refining, petrochemicals, and the marketing of fuels and lubricants - TOTAL is the world's 4th biggest IOC, with a 2018FY total asset of $224Bn and a market capitalization of $121.8Bn. TOTAL has a BUY recommendation, with a 2020YE PT of $59.3/share, meaning an upside potential of 31%, or a potential annualized return of 22%, against the closing price of $45.4 at August 30th, 2019, but with high risk. The current undervaluation of TOTAL shares is mainly explainable due to i) the pessimist expectations on global economy growth, that directly impacts on the world energy demand, ii) the exposure to commodities price volatility, iii) geopolitical instability and iv) uncertainty about the energy transition trend pace. Regarding the forthcoming industry trends, TOTAL has a focused strategy that integrates the challenges of climate change. Regarding this, it is expected that the Gas, Renewables & Power business segment, that includes the low carbon power generation and energy efficiency business, grow from 7.1% of TOTAL revenues in 2018 to 21.6% in 2023F. In addition, TOTAL solid financial position and commitment to the current shareholder return policy, even in lower-earning years, makes credible the dividend increases of +10% and the buyback program of up to $5Bn over the 2018-2020 period.

Suppose that one or more entities are stationed at some of the vertices of a simple graph and that an entity at a vertex can deal with a problem at any vertex in its closed neighbourhood. In general, an entity could consist of a robot, an observer, a legion, a guard, and so on. Informally, we say that a graph is protected under a given placement of entities if there exists at least one entity available to handle a problem at any vertex. Various strategies (or rules for entities placements) have been considered, under each of which the graph is deemed protected. These strategies for the protection of graphs are framed within the theory of domination in graphs, or in the theory of secure domination in graphs. In this thesis, we introduce the study of (secure) w-domination in graphs, which is a unified approach to the idea of protection of graphs, that encompasses known variants of (secure) domination in graphs and introduces new ones. The thesis is structured as a compendium of ten papers which have been published in JCR-indexed journals. The first one is devoted to the study of w-domination, the fifth one is devoted to the study of secure w-domination, while the other papers are devoted to particular cases of total protection strategies. As we can expect, the minimum number of entities required for protection under each strategy is of interest. In general, we obtain closed formulas or tight bounds on the studied parameters.

Full textAbstract:
Refractometry is a means to measure the refractive indices of liquids, gases, and dielectric solids, either isotropic or anisotropic, by observation of light refraction or reflection with a microscope, refractometer or other more specialized equipment. For anisotropic solids, refractometry by total reflection (RTR) is by far the simplest, most rapid, and precise method to determine the refractive indices, provided a polished surface of sufficient size exists. Its precision exceeds that for routine oil immersion techniques but compares less favorably to that for minimum deviation methods. However, minimum deviation requires large crystals and, moreover, specifically oriented prisms, one for each principal refractive index to be measured and, for triclinic crystals, one for each wavelength of measurement.
The phenomenon of polarized light reflection from randomly oriented anisotropic materials has been modeled because, only after a complete understanding of these phenomena could the R TR method be automated. The mathematics and physics required for this stem from theories and equations presented in the literature of ellipsometry, polarized light, and physical optics. These were then modified, rewritten, and unified to suit the requirements of R TR.
RTR, first used by Wollaston ( l 802a, l 802b ), was later perfected for the measurement of the refractive indices and orientation of biaxial minerals in thin section (Viola l 899a, l 899b, 1902; Comu 1901, 1902). RTR with the Abbe-Pulfrich refractometer yielded refractive indices to a precision of ±0.0002, or better. Later, Smith (1905a, 1905b) introduced a simpler refractometer, now known as the jeweler's refractometer, which had a precision of ±0.001 to ±0.002. This refractometer is still in use by gemologists. During this century familiarity with the early work has declined; thus several recent papers display a lack of knowledge of aspects of R TR which were already documented in the early 1900s.
A new automated refractometer, designed by Bloss, has precision of ±0.0002 and will be able to measure the refractive indices and orientation of a biaxial mineral in a petrographic thin section. Even for triclinic crystals, a single polished surface arbitrarily oriented will suffice for measurement of all three principal refractive indices, whatever the wavelength supplied. The design and testing of this refractometer has taken approximately three years. Two prototypes have been built and tested. Results from the second prototype are presented.Ph. D.

Målet med studien var att fastställa problemområden och att ta fram en problemställning. Efter det följde projektet den traditionella designprocessen med brief, idéprocess, skissprocess, prototyp och slutkoncept.Projektet har resulterat i ett fysiskt koncept som är tänkt att ligga tre år fram i tiden.

When these things move into the phone they become intangible. But what happens when more and more things are intangible, and interaction with this non-physical world remains flat and one dimensional? Are there better ways to reach, manage and "grab" this world?The project began with a study which largely consisted of trend analysis. The goal of this study was to identify problem areas and to develop a problem. Afterwards the project followed the traditional design process with a brief, idea process, sketching process, prototypes and final concept.The project has resulted in a physical concept that is supposed to be launched three years from now. The concept makes content from the intangible world more accessible to the user and explores new ways to interact with this content.

La question de la totalite dans l'art a ete posee explicitement par les artistes du xixeme siecle, en reference au statut non cloisonne de l'uvre d'art antique. Il semble qu'elle puisse trouver sa legitimite avec le cinema qui hesite encore entre une allegeance consensuelle et confortable au personnage et a la structure dramatique, et des audaces poetiques qui pourraient le mener vers une renovation, en inscrivant l'uvre dans le sillage des propositions esthetiques formulees par les artistes et theoriciens du vingtieme siecle : du dodecaphonisme au minimalisme, en passant par le bahaus et les courants spectraux. . . Mais plus qu'une synthese, ce travail se voudrait avant tout le deploiement d'hypotheses personnelles orientees dans le sens de la creation, et revendiquant une esthetique desfragments et de leur exploration, tant on admet qu'il y a en chaque fragment esthetique convoque a la realisation de l'uvre audiovisuelle, une composition par strate qui justifie une lecture verticale et infiniment aventureuse.

Full textAbstract:
Acutumine is a tetracyclic alkaloid isolated from the Asian vine Menispermum dauricum with selective T-cell cytotoxicity and antiamnestic properties. We have developed a total synthetic route to this congested alkaloid, during which we also found a novel, stereoselective radical-crossover reaction that combines an intramolecular radical conjugate addition with a subsequent enolate hydroxylation. Key features of this synthesis also include a reagent-controlled diastereoselective ketone allylation, an anionic oxy-Cope rearrangement to form a congested quaternary sterocenter, a pyridine-mediated selective ozonolysis, and a Lewis acid promoted Michael-type cyclization.

La thèse décrit la première synthèse totale de l'Eucophylline, le fragment sud de l'alcaloïde Leucophyllidine récemment isolé à partir de Leuconotisgriffithii et L. eugenifolius. La synthèse en 10 étapes comprend une nouvelle méthode d’accès au squelette azabicyclo[3.3.1]nonane par un processus de carbooximation radicalaire d'oléfines à trois composants. Au cours de ces études, nous avons également isolé des énamines présentant des stabilités inhabituelles résultant de leur conformation bicyclique tendue. La synthèse de la partie éburnane, le fragment nord de la Leucophyllidine, a été réalisée grâce à une nouvelle réaction radicalaire de carbo-cyanation à trois composants. Cette réaction radicalaire s'est révélée efficace pour installer le groupement fonctionnel nitrile sur des oléfines, et éventuellement former des centres quaternaires, notamment dans des structures complexes, puisqu'une bonne tolérance aux différents groupes fonctionnels a été observée. Le couplage biomimétique entre le squelette éburnane et l'Eucophylline a finalement été étudié en utilisant des modèles de structure similaire. Les résultats préliminaires de cette étude ont montré que l'absence d'effet gem-diméthyle dans le modèle éburnane empêche probablement la formation de l'imine cyclique,intermédiaire-clé dans le couplage désiréThe thesis describes the first total synthesis of Eucophylline, the south fragment of the Leucophyllidine alkaloid recently isolated from Leuconotis griffithiiand L. eugenifolius. The 10-step synthesis encompasses a new straight forward method to access to the azabicyclo[3.3.1]nonane skeleton through a free-radical three-component olefinic carbo-oximation process. During these studies, we also isolated enamines exhibiting unusual stabilities resulting from their strained bicyclicconformation. The synthesis of the Eburnane part, the north fragment of Leucophyllidine, was developed relying on a new free-radical three-component Carbo-Cyanation reaction. This new reaction showed high tolerance toward different functional groups and provided an efficient mean to install the nitrile group in complex structures and to introduce quaternary centers. The biomimetic coupling between the Eburnane and Eucophylline fragments was finally studied using structurally similar models. Preliminary results of this model study showed that absence of a gemdimethyleffect in the Eburnane model probably prevents the formation of the cyclicimine, key intermediate for the desired coupling

Le manuscrit de thèse traite de la synthèse totale de molécules naturelles de structures particulièrement intrigantes. Deux familles de molécules naturelles issues du monde marin ont été ciblées dans ce travail : les halichonadines et les araiosamines.- La famille des halichonadines nous plongent dans le domaine des terpènes d’origine marine. Isolées d’éponges du genre Halichondria, deux structures ont particulièrement retenues notre attention : les halichonadines K et L. En effet, non seulement, ces deux molécules complexes contiennent une partie terpénique de type eudesmane (halichonadine C, un isonitrile naturel) mais aussi un cœur central de nature peptidique constitué, notamment, d’une pipéridine disubstituées par des fonctions acide carboxylique. Une partie est dédiée à comprendre comment dans la nature, des molécules de type isonitrile sont produites et peuvent réagir dans des voies de biosynthèse. Par ailleurs, le travail expérimental s’est organisé de la façon suivante :1- Concevoir une synthèse efficace de l’halichonadine C. Une stratégie au départ de la santonine est développée. La présence d’un groupement isopropyle sur la structure finale s’est avérée poser un nombre important de problèmes. Cependant, un composé très avancé a été obtenu figurant tout le squelette et l’atome d’azote nécessaire à la finalisation de la synthèse de l’halichonadine C.2- Concevoir une synthèse du cœur central permettant de contrôler la stéréochimie relative des deux fonctions carboxyliques en alpha de l’atome d’azote. Plusieurs stratégies ont été étudiées faisant appel notamment à une double addition de Michael ou à des réactions inspirées de la synthèse de la tropinone. Le cœur central est ainsi accessible en un nombre très limité d’étapes.Les résultats sont très encourageants et la quasi-totalité des pièces du puzzle sont là pour entrevoir rapidement la synthèse totale des halichonadines K et L.- La partie consacrée aux araisoamines (A-D, extraites d’éponges du genre Clathria) est exploratoire et permet de proposer des pistes synthétiques prometteuses pour l’accès bio-inspiré à ces molécules naturelles constituants un défi pour le chimiste. Un des défis relevés dans le travail est de concevoir des analogues synthétiques d’intermédiaires biosynthétiques très réactifs tels que des indoles aldéhydiques très instables. Une méthode pour générer in situ de telles entités a été étudiée. Les premières expériences ont été appliquées à la synthèse des « pyridiniums de Discodermia » et apparaissent prometteurs.Les travaux menés s’inscrivent dans « l’art de la synthèse totale » mais sont aussi toujours en lien avec le souci de mieux comprendre « chimiquement » comment des architectures moléculaires complexes s’assemblent au cours des voies de biosynthèse des substances naturellesThe work described in this PhD dissertation is dedicated to the total synthesis of intriguing natural product structures. Two distinct families of natural substances of marine origin have been targeted in this work: the halichonadins and the araiosamines.- With the halichonadins, we plunge into the marine terpene chemistry. Isolated from sponges of the genus Halichondria, two structures have particularly drawn our attention: halichonadins K and L. Indeed, besides two subunits of terpene origin (namely halichonadin C, a natural isonitrile) with an eudesmane skeleton, a central core of peptidic origin is also original (especially a carboxylic acid disubstituted piperidine ring). A part of the work is dedicated to understanding how, in nature, isonitrile natural products may be formed and may react. The experimental part is organized according to the two following topics:1- Devise an efficient and straightforward total synthesis of halichonadin C. A strategy starting from santonin has been studied and developed. The presence of an isopropyl pending group has attracted many synthetic problems. Anyhow, an advanced intermediate comprising the whole skeleton and the crucial nitrogen atom of the target has been reached and provides good hopes for the access to halichonadin C.2- Conceiving a strategy of the stereocontroled access to the central piperidine ring of halichonadins K and L. Several strategies have been evaluated including the recourse to double Michael additions and reactions inspired by Robinson’s tropinone synthesis. The peptidic central core is now accessible in a limited number of steps.Most of the pieces of the puzzle are in our hands at the end of this PhD to secure a rapid access to the complex targets that constitutes halichonadins K and L.- The chapter dedicated to araiosamines (A-D, isolated from sponges of the genus Clathria) is exploratory and allows to propose promising strategies for a bio-inspired synthesis that constitutes true challenges for the organic chemists. One of the challenges to take up is to prepare highly reactive indole aldehyde units that could be foreseen as chemical equivalents of postulated biosynthetic intermediates. A method to generate in situ such units is studied. The first applications have been directed to the synthesis of “Discodermia pyridiniums” and appear to be promising towards the total synthesis of these molecules.The work conducted during this PhD take place in the framework of the “art of total synthesis”. But, in our strategies, the chemical understanding of biosynthetic pathways is never far away

Full textAbstract:
The airline industry is a highly competitive market. Particularly after the major liberalization in the industry, the competition carried a step forward for all the concerned companies. Airline industry is a very dynamic market also; the expenses of a single operation may change substantially in a very short time period, which could be due to the fickle regulations or the fluctuation of oil prices. At any time, for a certain destination, a new airline company can start its operations and become a competitor, which can result in a market share loss for current operators. In such an environment, airline companies strive to maximize their revenues in every single flight. Load factors of a flight, classification, and pricing of airline tickets in a flight are determinative on the revenue of a single operation. In order to maximize revenue for its operations, companies should have a broad range of information about airline market conditions and passenger profile and preferences for every destination that they operate. Turkish Airlines, which is the largest airline company of Republic of Turkey and increasing its global awareness day by day, also strives to maximize its revenues per flight. In order to do so, Turkish Airlines needs to have suitable decisions regarding the capacity issues (determination of type and number of aircrafts, and flight frequencies) which will be then used worldwide in the different branches of company. These reasons lead to the increased need for the company to adopt practical total demand analysis in its operating destinations. The company aims to specify the factors, which are effective on the change of total demand for every destination. Turkish Airlines also strives to make most accurate demand forecasting in order to manage the peaks and troughs of the company’s flights. This project was brought to agenda in order to help this company to address this issue and was initiated with the purpose of making a total demand analysis for specified destinations. Destinations are from Stockholm to Athens, Thessalonica, New Delhi, Mumbai, Istanbul, Bangkok, and Dubai. This study is a quantitative study. Chosen demand factors, which constitute the total airline traffic between destination cities, are analyzed with respect to change in total demand. Various demand-forecasting methods are also applied in order to determine the best forecasting method for each destination, which is compatible with the quantitative approach. Results of the study are directly related to the airline market conditions of aforementioned destinations. Results are presented in four subheadings for every destination; overview of airline market, competition level of airline market, factors regarding the destination and demand forecasting for the destination. This study provides important information to Turkish Airlines regarding total demand analysis of specified destinations. Company learns the common factors (price, total amount of luggage, etc.) and the destination specific factors (language of crew, Frequent Flyer Programs, etc.) that are effective on the change of demand. Company may use this information in order to increase its market share (amount of passengers carried in a certain destination by Turkish Airlines from total demand) for specified destinations. With the help of this study, the company can make an accurate demand forecasting for Turkish Airlines’ future flights, which can be used in planning activities like determining the type of aircraft and flight frequency for a destination, and pricing of flight tickets through different passenger segments.
