Essa propriedade possui grande aplicabilidade nas ind?strias aliment?cia e farmac?utica, principalmente em an?lises de DNA. Para esse trabalho, foram preparadas solu??es aquosas em concentra??es diferentes de agarose. Medidas de espalhamento din?mico de luz foram feitas, enquanto se alterava a temperatura do sistema, a fim de obter estruturas mais ou menos organizadas das macromol?culas. Para as medidas de espalhamento, a equa??o Kohrausch-William-Watts (KWW) foi ajustada aos dados, de modo a obter a taxa de relaxa??o m?dia do processo. Adicionalmente, foram feitos testes de reologia das amostras, tamb?m com a varia??o da temperatura. Para ambas as t?cnicas, foram feitos ajustes matem?ticos, com a inten??o de estudar a transi??o h?lice-novelo das cadeias polim?ricas no decorrer da altera??o da temperatura, relacionando-as atrav?s do c?lculo da energia de ativa??o aparente do processo. Nas duas abordagens foi constatado que a energia tende a diminuir para solu??es dilu?das e para altas temperaturas. / The agarose is a natural polymer extract from red algae (Rhodophyceae). This polysaccharide can form physical gels when is removed heat from the system. This property has great applicability in the food and pharmaceutical industries, particularly in DNA analysis. For this work we prepared aqueous solutions at different concentrations of agarose. Measures of Dynamic Light Scattering (DLS) were made while the system temperature was altered so as to obtain structures more or less organized of macromolecules. For DLS measurements, the Kohrausch-William-Watts equation (KWW) was fitted to the data to obtain the average of relaxation rate of the process. Additionally rheometry tests were made also with the temperature variation. For both techniques, were made mathematical adjustments with the intention of studying the helix-coil transition of the polymer chains during the temperature change, relating them by calculating the apparent activation energy. In both approaches it was found that energy tends to decrease for dilute solutions and higher temperatures.

Nos ?ltimos anos, estudos t?m investigadoa in?u?ncia da geometria das amostras no efeito MI, em particular, sistemas na forma detricamadas e de Meander-line, separadamente. Baseado nisso, este trabalho busca umaintegra??o destas duas geometrias com o objetivo de estudar as propriedades estruturais eo comportamento magn?tico quase-est?tico e din?mico em tricamadas de [NiFe/Cr/NiFe].As amostras foram produzidas atrav?s da t?cnica de Magnetron Sputtering, sobre subs-trato amorfos de vidro, com espessura das camadas ferromagn?tica variando entre 75 nm e142.5 nm, enquanto a espessura da camada de Cr varia entre 15 nm e 150 nm, totalizandoum conjunto de 10 amostras. Em particular, a espessura total da tricamada foi mantidaconstante em 300 nm independente da amostra produzida. Associado a isto, para cadaconjunto de espessura acima citado foram utilizados tr?s diferentes geometrias no planodo substrato, a primeira na forma retangular, tradicionalmente estudada, e as outrasduas na forma Meander-line, produzidas utilizando-se m?scaras durante o crescimentodos ?lmes. A caracteriza??o estrutural, atrav?s da difra??o de raios X, mostrou um com-portamento cristalogr??co tradicionalmente encontrados para ?lmes de NiFe crescidos emsubstratos amorfos, com uma textura [111]. A caracteriza??o magn?tica quase-est?tica foirealizada atrav?s de curvas de magnetiza??o, obtidas para diferentes dire??es de campomagn?tico aplicado no plano do ?lme em rela??o ao eixo principal da amostra, atrav?sda t?cnica de magnetometria de amostra vibrante (VSM). De uma forma geral, as curvasde magnetiza??o revelam propriedades magn?ticas isotr?picas no plano e s?o fortementedependentes da espessura das camadas ferromagn?ticas de NiFe. Por outro lado, umafraca depend?ncia com a geometria estudada (retangular ou Meander-line) ? observado,como esperado. Finalmente, para o estudo da din?mica da magnetiza??o, foi utilizada at?cnica de magnetoimped?ncia em uma ampla faixa de campo (?700 Oe) e frequ?ncia (0.5at? 3.0 GHz). Al?m disso, duas con?gura??es entre campos e correntes foram exploradas,denominadas aqui de con?gura??o longitudinal (campo e corrente na mesma dire??o) etransversal (campo aplicado perpendicularmente ? corrente). As medidas de magnetoim-ped?ncia apresentam uma estrutura de picos duplos ou m?ltiplos picos, caracter?sticos doefeito FMR, maior respons?vel pelas varia??es do efeito MI no intervalo de frequ?nciasestudado. Com respeito a depend?ncia do efeito em fun??o da raz?o entre as espessurasdas camadas de NiFe e Cr, ? poss?vel observar uma forte in?u?ncia da anisotropia mag-n?tica na estrutura de picos das curvas de MI, principalmente nas amostras com camadasferromagn?ticas mais espessas, este fato est? ligado a contribui??o de anisotropia parafora do plano. Por ?m, uma an?lise das curvas em rela??o a geometria das amostras re-vela mudan?as no comportamento da din?mica de magnetiza??o, acarretando em curvasassim?tricas e uma grande complexidade na estrutura de picos observado.

H? consenso nos estudos anteriores quanto ? defini??o e ?s causas que origina o EC. No entanto, os modelos propostos para a quantifica??o e o desenvolvimento de solu??es para a mitiga??o do EC ainda constituem um amplo campo de pesquisa, face as lacunas identificadas na literatura, a exemplo de an?lises que contemplem composto de Marketing, capacidade de transporte, sazonalidade e custos. Desse modo, este trabalho tem como objetivo desenvolver um modelo de apoio ? gest?o de cadeias de suprimentos para avaliar o impacto que a??es de Marketing, desenvolvidas em per?odos delimitados de tempo para estimular a comercializa??o dos produtos, exercem no EC. O racionamento no fornecimento, o lead time e o estoque m?nimo, que s?o agentes causadores da variabilidade da demanda, al?m da diferencia??o dos itens segundo a classifica??o ABC, foram considerados na estrutura??o do modelo. O estudo, ent?o, pode ser enquadrado como explorat?rio, descritivo e explicativo. Quanto a abordagem, a pesquisa assume um car?ter qualitativo e quantitativo, de natureza aplicada, mediante o levantamento de dados junto a uma empresa atuante no varejo da constru??o civil, para auxiliar na identifica??o de valores de refer?ncia para validar o modelo proposto. Para viabilizar o estudo, diante da complexidade decorrente do relacionamento entre as vari?veis envolvidas, foi utilizada como ferramenta a simula??o, a partir da Din?mica de Sistemas (DS), pois trata-se de um ambiente controlado, possibilitando a replica??o com facilidade dos experimentos, viabilizando a constru??o de cen?rios e favorecendo an?lises, cujos resultados auxiliam o processo de tomada de decis?o. As simula??es executadas, respaldadas nas refer?ncias bibliogr?ficas, permitiram atestar que o resgate do saldo de fornecimento na composi??o do pedido de compra reduz significativamente o EC; a presen?a de mais canais de distribui??o elevam o EC; o estabelecimento de pontos m?nimo e m?ximo para o estoque, em conformidade com a classifica??o ABC, permite reduzir o EC, dada a representatividade dos itens; a avalia??o dos n?veis de estoque e dos saldos de fornecimento atuam como elementos reguladores, podendo acarretar na redu??o do EC; e a pr?tica de calend?rios de promo??o e de racionamento do fornecimento incidem no aumento do EC. Conclui-se que o modelo proposto ? capaz de mitigar o EC na cadeia de suprimentos. / The bullwhip effect (BE) is a phenomenon present in the supply chains characterized by the variability of the demand, causing an amplification upstream of the quantities handled, implying in the formation of excess stocks and, consequently, in the increase of logistic costs. There is consensus in previous studies regarding the definition and causes of BE. However, the proposed models for the quantification and development of solutions for BE mitigation still constitute a broad field of research, given the gaps identified in the literature, such as analyzes that contemplate the composition of Marketing, transport capacity, seasonality and costs. Thus, the objective of that work is to develop a support model for the management of supply chains to evaluate the impact that Marketing actions, carried out in defined periods of time to stimulate the commercialization of the products, exercise in the BE. Supply rationing, lead time and minimum inventory, which are agents that cause variability in demand, besides the differentiation of items according to the ABC classification, were considered in the model structuring. The study, then, can be classified as exploratory, descriptive and explanatory. Regarding the approach, the research assumes a qualitative and quantitative nature, of an applied nature, through the collection of data from a company that operates in the retail of civil construction, to assist in the identification of reference values to validate the proposed model. In order to make the study feasible, due to the complexity resulting from the relationship between the variables involved, it was used as a tool the simulation, from the System Dynamics (SD), because it is a controlled environment, allowing the replication with ease of the experiments, enabling the construction of scenarios and favoring analyzes, the results of which help the decision-making process. The simulations carried out, supported by bibliographical references, allowed us to confirm that the redemption of the supply balance in the purchase order composition significantly reduces the BE; the presence of more distribution channels elevates the BE; the establishment of minimum and maximum points for the stock, in accordance with the ABC classification, allows to reduce the BE, given the representativeness of the items; the evaluation of stock levels and supply balances act as regulatory elements, which may lead to the reduction of the BE; and the practice of promotion and supply rationing calendars focus on increasing the BE. It is concluded that the proposed model is able to mitigate the BE in the supply chain.

In its parasitic phase, the larva is the cause of furuncular myiasis occurring in a large variety of endothermic animals, with most frequent occurrence in cattle, dogs and humans. The lack of information concerning dermatobiosis creates difficulties in its diagnosis. By means of a systematic review of the literature on the subject, it can be verified that this fly shows versatility in its phoresis and has a vast list of phoretic records. Field studies are restricted to observation of its larval form, because its adult form is difficult to observe, making this a rare event. With the intention of evaluating and comparing fluctuation in the population of D. hominis, searching for correlations between the incidence of Botfly larval infestations and climatic factors and their distribution on the body surface of cattle, two areas of study were selected, in which field collections were carried out twice monthly for counting the number of larvae in the herds. Discrepancies were discovered in the average number of larval nodes in cattle between these areas of study. These nodules showed variation in their bodily distribution on the cattle, with a higher incidence in the anterior region, compromising the quality of the animals? skins for economic purposes. In one of the areas, there was a correlation between the average number of larvae and the temperature and precipitation. These climatic factors are related to edaphic characteristics, influencing the penetration of the L3 larvae and the pupal period. For a greater understanding of the dynamics and fluctuations in the population of D. hominis in these areas, ample monitoring is needed to determine if the results encountered in this study are atypical or influenced by local characteristics. Currently, the demand for research is for methods of controlling the dermatobiosis, with emphasis on integrated plague management. Other deficiencies include following the Botfly?s complete life cycle in the laboratory and understanding certain peculiar adaptations, such as atrophied oral apparatus / A Dermatobia hominis (Linneaus Jr., 1781) (Diptera, Cuterebridae), popularmente conhecida como mosca do berne, ?nica esp?cie do g?nero e end?mica da regi?o Neotropical, ? um inseto holomet?bolo com uma fase de vida livre na sua forma adulta e uma fase parasit?ria obrigat?ria em sua forma larval. Em sua fase parasit?ria, a larva ? causadora da mi?ase furuncular ocorrendo em uma grande variedade de animais endot?rmicos, com ocorr?ncia mais frequente em bovinos, c?es e no homem. A falta de informa??o sobre a dermatobiose gera dificuldade em seu diagn?stico. Atrav?s de uma revis?o sistem?tica da literatura sobre o assunto, verifica-se que a mosca apresenta versatilidade para a foresia e conta com vasta lista de registros de for?ticos. Os estudos em campo se restringem a observa??es sobre sua forma larval, pois sua forma adulta ? de dif?cil observa??o tornando este evento raro. Visando avaliar e comparar a frequ?ncia populacional de D. hominis, buscando correla??o entre a incid?ncia do berne e fatores clim?ticos e a sua distribui??o na superf?cie corporal de bovinos, foram selecionadas duas ?reas de estudo, as quais foram realizadas coleta de campo quinzenalmente para o levantamento do n?mero de bernes no rebanho. Foram encontradas diverg?ncias no n?mero m?dio de n?dulos de berne em bovinos entre as ?reas de estudo. Os n?dulos apresentaram varia??o na distribui??o corporal dos bovinos, tendo maior incid?ncia na regi?o anterior, comprometendo a qualidade da pele do animal para fins econ?micos. Em uma das ?reas houve correla??o entre o n?mero m?dio de bernes e a temperatura e precipita??o. Esses fatores clim?ticos est?o relacionados ?s caracter?sticas ed?ficas, influenciando a penetra??o das larvas L3 e o per?odo pupal. Para o maior entendimento da din?mica e frequ?ncia populacional da D. hominis nessas ?reas, h? necessidade de amplo monitoramento para averiguar se os resultados encontrados neste estudo s?o at?picos ou influenciados por caracter?sticas locais. Atualmente a demanda de pesquisa est? em m?todos para controle da dermatobiose, com destaque para o manejo integrado de pragas. Outras lacunas est?o na realiza??o de seu ciclo completo em laborat?rio e compreens?o de adapta??es peculiares, tais como aparelho bucal atrofiado.

Vliv vneseného tepla na vlastnosti a strukturu svarového spoje duplexní oceli. / Influence of a particullar heat on properties and structure of duplex steel welded joint

Němec, Karel January 2010 (has links)
The research project is focused on an influence of a particullar heat on properties and structure of duplex steel DIN 1.4462. Samples prepared by using different welding speeds 10, 15, 20, 25, 30 cm.min-1, were tested for tensile, metalographical analysis and hardness test. Experimental results proved the optimal welding speed for material with 2 mm thickness to be 15 cm.min-1. Usage of lower speed 10 cm.min-1 led to formation of hot cracks while higher speeds 20, 25, 30 cm.min-1 didn‘t cause material penetration.

Beitrag zur Ermittlung der Kerbwirkung an Zahnwellen mit freiem und gebundenem Auslauf

Daryusi, Ali 28 November 2008 (has links)
Durch die zunehmende technologische Entwicklung des Getriebe-, Gelenkwellen-, Werkzeugmaschinen-, Kraftfahrzeug-, sowie Landmaschinenbaus steigen die zu übertragenden Leistungen und Drehmomente enorm. Dies führt zu einem wachsenden Bedarf an formschlüssigen Profilwellenverbindungen und deren erhöhter Lebensdauer und Genauigkeit. Hierbei bilden die Zahnwellenverbindungen (ZWVen) mit Evolventenflanken nach DIN 5480 /N1/ den Regelfall für eine Vielzahl der Anwendung. Abhängig von Festigkeitsüberlegungen, Herstellungsverfahren und Platzbedarf treten in der Praxis nahezu ausschließlich die folgenden zwei Grundtypen auf. Es handelt sich dabei zum Ersten um die Zahnwelle (ZW) mit freiem Auslauf.Die zweite Geometrievariante ist die Zahnwelle mit gebundenem Auslauf, die eine nach DIN 471 /N2/ genormte Sicherungsringnut (SRN) enthalten kann. Zahnwellenverbindungen dienen zur Übertragung großer, wechselnder und stoßartiger Drehmomente ohne zusätzliches Verbindungselement durch die Profilierung der Welle und Nabe. Axiale Verschiebbarkeit unter Last, Profilverschiebungsmöglichkeit, einfache Montage und Demontage sowie die Herstellung mit hochleistungsfähigen umformenden und spanenden Massenfertigungsverfahren, die die Herstellungskosten verhältnismäßig niedrig halten, sind technisch bedeutsame Eigenschaften, die zum ansteigenden Einsatz von ZWVen führen (z.B. /N1/, /Vil84/, /Koh86/ und /Wes96/). Starke Kerbwirkung und erhebliche Überdimensionierung benachbarter Gestaltungszonen sind die wesentlichen Schwachpunkte der Profilverbindungen. Eine große Anzahl (ca. 80 %) von Ausfällen im Maschinenbau ist auf Schäden an Achsen und Wellen infolge konstruktiv bedingter Kerben zurückzuführen (z.B. /N3/ und /Hai89/). Speziell im Bereich der hochbeanspruchten Profilwellen-Verbindungen kommt es auf Grund der starken Querschnittsveränderungen und der häufig angewandten Ausläufe und Formelemente, z. B. Zahn- und Keilwellen zu Kerbwirkungen, die erhebliche örtliche Spannungskonzentrationen sowohl im Zahnfußbereich und Zahnlückenauslauf als auch im Bereich der Verbindung selbst verursachen. Diese Beanspruchungskonzentrationen sind fast in der Hälfte aller Zahnwellenbrüche die häufigste Ursache für Dauerbrüche (Ermüdungs- bzw. Schwingungsbrüche) und für Schäden (bleibende Verformung, Anriss, Gewaltbruch) infolge Maximalbelastung. Hier trifft die Lastüberhöhung am Welle-Nabe-Verbindungsrand mit dem Steifigkeitssprung des Verzahnungsendes auf der Welle zusammen /Die93/. Die erwähnten Schadensfälle belegen, dass der heutige Kenntnisstand über eine beanspruchungsgerechte Auslegung von Zahnwellen noch recht lückenhaft ist. Deshalb sind neue Erkenntnisse über Form- bzw. Kerbwirkungszahlen bei Einzel- und Mehrfachkerben von scharf und weniger scharf gekerbten Zahnwellen mit Auslauf für eine treffsichere Festigkeitsberechnung erforderlich und stellen damit die Hauptschwerpunkte dieser Arbeit dar. Das vorliegende Forschungsprojekt, welches sich erstmals mit der Ermittlung der Beanspruchungen in torsions-, und biegebelasteten Zahnwellen mit freiem und gebundenem Auslauf befasst, wurde im Rahmen der Forschungsvereinigung für Antriebstechnik e.V. (FVA) unter der Nummer T 467 und dem Forschungsthema „ Ermittlung der Kerbwirkung bei Profilwellen für die praktische Getriebeberechnung von Zahnwellen“ initiiert und untersucht.

Ökologische Bewertung von Reinigungsprozessen in der Oberflächentechnik - Möglichkeiten zum Einsatz integrierter Umweltschutztechnologien

Huber, Veit 05 February 2004 (has links)
Die ökologische Bewertung von Prozessen gewinnt zunehmend an Bedeutung. Der Betrachtungsgegenstand dieser Arbeit ist der Prozess Reinigen, der in der Oberflächentechnik breite Anwendung findet. Mit einer Systematisierung und Wertung der Bedeutung der Hauptverfahren wird sich dann auf den Prozess des wässrigen Reinigens konzentriert, der den größten Anteil der Anwendungen ausmacht. Die Analyse des Technologiefeldes ergab ein breites Spektrum möglicher Verfahrensvariationen. Dies hat zur folge, dass fast jede einzelne Reinigungsanlage auf den jeweiligen Einsatzzweck mit Hilfe der möglichen Anwendungsparameter optimiert werden kann. Ziel dabei ist es, die Anlagen ökonomisch-ökologisch optimal zu betreiben. Dieses Ziel kann durch Investitionen in bereits angebotene Umweltschutztechnologien auch mit Kostenvorteilen erreicht werden. Die in der Arbeit vorgestellten und systematisierten integrierten Umweltschutztechnologien sind geeignet, die ebenfalls dargelegten ökologischen Schwachstellen des Prozesses auszugleichen. Mit dem Einsatz dieser Technologien steigt die Komplexität der Prozessführung, so dass sich daraus Forschungsbedarf zur automatisierten Überwachung und Regelung dieses Prozesses unter Einbeziehung neuer Sensorik ergibt. Weiterhin wird die Norm DIN ISO 14031 zur Umweltleistungsbewertung vorgestellt und ein Vorschlag für potentielle prozessorientierte Umweltziele sowie entsprechende Kennzahlen unterbreitet. Die kritische Betrachtung des Reinigungsprozesses aus ökologischer Sicht hat gezeigt, dass bereits ein hohes Aktivitätsniveau bei der Forschung zu diesem Prozess zu verzeichnen ist und somit dessen Bedeutung für Wirtschaft und Umwelt unterstreicht.

Den poetiska (religions)kunskapen

Leo, Andreas January 2012 (has links)
Detta examensarbete behandlar den sufiska poeten Jalal Ud-din Rumis dikter som läromedel inom ämnet religionskunskap. Genom att föra samman de två fenomenen religion och poesi undersöker jag på vilket sätt de förhåller sig till varandra i fråga om kunskap om och förståelse inför livet och världen. Vidare behandlar jag sedan hur dessa kopplingar, mellan poesin och religionen, i så fall skulle kunna användas inom religionsundervisningen. Studien är i huvudsak teoretisk med ett religionsdidaktiskt fokus och kretsar kring tolkningen av två dikter.
