Ninety 17 mm length bovine roots were endodontically treated up to K File #80, to a working length of 16mm, using crown-down technique. During the instrumentation all roots received 1ml of irrigation solution (5.25% NaOCl or 2% CHX) between each instrument using a Navitip® needle. The samples were randomly divided into six groups, according to final irrigation and activation system: PPIN (Control 1): PPI + 5.25% NaOCl; PUIN: PUI + 5.25% NaOCl; CUIN: CUI + 5.25% NaOCl; PPIC (Control 2): PPI + 2% CHX; PUIC: PUI + 2% CHX and CUIC: CUI + 2% CHX. For PPIN/PPIC a Navitip® needle was used to deliver the irrigation solution. For PUIN/PUIC the same Navitip® needle was used and the irrigant solution was activated by a stainless steel file E1 Irrisonic® mounted on a EMS® Ultrassonic unit, for 10-seconds. For CUIN/CUIC the irrigation and activation were performed by continuous agitation and irrigant solution delivery , for 10-seconds, using the same stainless steel file E1 Irrisonic® mounted on EMS® Ultrassonic unit. The final irrigation of all groups was performed using 2ml irrigation solution + 1ml 17% EDTA + 2ml irrigation solution. After canal preparation, the fiber posts Whitepost® DC n.2 were cemented with dual cure resin cement RelyX ARC® and adhesive system Single Bond Universal®. The roots were sectioned into 1mm-thick slices, on cervical, medial and apical thirds. After 7 days, the slices were submitted to push-out test on universal testing machine EMIC (0,5mm/min, 150N). Mean values of bond strength (BS) were compared using two-way ANOVA and Tukey’s test (p≤0.05). BS values (±dp) were: PPIN 4.46 (1.43); PUIN 6.13 (2.35); CUIN 7.41 (1.83); PPIC 3.59 (1.70); PUIC 5.49 (1.41); CUIC 6.0 (1.63). Comparing irrigation solutions, the results were similar with each irrigation systems. CUI showed the best bond strenght values and PPI the worst one, similar to PUI. Analyzing the root thirds, CUIN showed significant diferences at apical third and CUIC showed diferences at middle third. Conclusion: CUI was the best activation system, regardless of the irrigation solution choice, providing better results at fiber post bond strenght, mainly at apical third. / O objetivo neste estudo foi avaliar a influência de três técnicas de irrigação endodôntica: PPI (Irrigação por Pressão Positiva ou Irrigação Manual), PUI (Irrigação Ultrassônica Passiva) e CUI (Irrigação Ultrassônica Contínua), na resistência à extrusão (push-out) de pinos de fibra de vidro utilizando NaOCl 5,25% (hipoclorito de sódio) ou CHX 2% (clorexidina). Foram utilizados 90 dentes bovinos, as coroas cortadas com disco diamantado, obtendo-se raízes com 17 mm de comprimento. As raízes foram tratadas endodonticamente pela técnica coroa-ápice até o instrumento de memória n°80, a uma profundidade de 16 mm e divididas aleatoriamente em 6 grupos de acordo com o protocolo de ativação/substância química final: PPIN: PPI + NaOCl 5,25%; PUIN: PUI + NaOCl 5,25%; CUIN: CUI + NaOCl 5,25%; PPIC: PPI + CHX 2%; PUIC: PUI + CHX 2%; e CUIC: CUI + CHX 2%. A irrigação final de todos os grupos foi realizada com 2ml de substância química + 1ml de EDTA 17% + 1ml de substância química. Nos grupos PPIN e PPIC foram utilizadas pontas endodônticas Navitip® para a irrigação. Nos grupos PUIN e PUIC, foram utilizadas as mesmas pontas endodônticas Navitip® e ativadas passivamente com inserto E1 IRRISONIC® acoplado ao Ultrassom EMS® (10s), frequência de 32.000 Hz, sem renovação da substância química. Nos grupos CUIN e CUIC a substância química foi continuamente ativada e renovada com inserto E1 IRRISONIC® acoplado ao Ultrassom EMS® (10s). Todas as raízes foram lavadas com água destilada para remoção dos resíduos e secas com cones de papel absorvente. As raízes tiveram os ápices selados com gutta percha. Após o preparo dos condutos, foi feita a cimentação do pino de fibra de vidro Whitepost® DC n.2 com cimento resinoso dual RelyX ARC® e sistema adesivo Single Bond Universal®. As raízes foram seccionadas transversalmente em 9 fatias, de aproximadamente 1mm de espessura, divididas entre os terços cervical, médio e apical. Após 7 dias, as fatias foram submetidas ao teste de extrusão push-out em máquina de ensaio universal EMIC (0,5mm/min,150N). Os valores de resistência adesiva (RA) foram submetidos a ANOVA a 2 critérios e teste de Tukey para comparação das médias (p≤0,05). Resultados: Os valores médios em MPa (±dp) foram: PPIN 4,46 (1,43); PUIN 6,13 (2,35); CUIN 7,41 (1,83); PPIC 3,59 (1,70); PUIC 5,49 (1,41); CUIC 6,0 (1,63). Comparando-se as soluções irrigadoras, os resultados foram semelhantes com cada tipo de técnica. CUI foi a técnica que apresentou os melhores valores de adesão e PPI apresentou o menor valor, sendo semelhante à PUI. Analisando os terços radiculares, o grupo CUIN demonstrou diferença estatisticamente significante na região apical e médio respectivamente: 5,48 (2,47) e 5,92 (2,46). Conclusão: CUI foi a melhor técnica de irrigação em relação à adesão dos pinos de fibra de vidro, independentemente da solução irrigadora utilizada, influenciando positivamente na adesão da região apical.

The purpose of this essay is to investigate the emigration from Sunnerbo district, whichis located in western Kronoberg county, during the 1880s. The goal is to find out whothe emigrants were and how and where they planned to emigrate. This is accomplishedby looking at the emigrants' gender, age, title or professional title as well as familyrelationship and country of destination. Information has been found in digital archives,relocation books have been read in the Digital Archive and population reports have beenread in the National Archives' digital research hall. From this material it can be deducedthat 7432 people emigrated in the 1880s, corresponded to 17.6% of Sunnerbo's averagepopulation and that 49% of the emigrants were women. The majority were in the agerange 20-29 years with a profession linked to agriculture. One third emigrated with theirfamilies and 85.8% emigrated to North America. The results of the empirical study arediscussed with previous research and theories related to migration. An analysis of themigration within Sunnerbo district will also be carried out to discuss differences betweenthe 23 parishes within the district. / Denna uppsats syfte är att undersöka emigrationen från Sunnerbo härad, som ligger ivästra Kronobergs län, under 1880-talet.

This thesis deals with implementation of another supplier to the Kanban system in the company Lexmark International s.r.o. The first part of the thesis is concerned with a theoretical finding from literature concerning inventory, types of supplies, level of inventory, calculation of supplies and, in addition, the Kanban and JIT system. The operative part is dedicated to analyses of the current status of the company using of the Porter´s, SWOT and SLEPTE analyses and, more over, the process of supplies by the method of PUSH and PULL – Kanban system in the company. The following chapter compiles the project on optimalization and decreasing of inventory by implementation of the Kanban system by Asian suppliers whose inventory coveres a substantial part of the company´s value. The objective of this thesis is to find whether the implementation of Kanban reduces level of inventory and whether their costs can be reduced in comparison with the last years and last but not least whether the implementation can be useful.

One of the main goals when designing new furniture today is to make life easier for the user of the product, for this reason the electrical push open has been developed. In the present day it is mostly used in the kitchen environment in both drawers and doors. The function of an electrical push open is to open a drawer or door automatically when the user gives the drawer or the door a small push. The objects of the project have been to develop concepts of electrical push opens, build a simple prototype, conduct a cost analysis and to make a function description of the push open. Delimitations of the project were to focus on a TV-bench and not focus on developing the software for the push open. The project was conducted in five different phases. The first phase was to define the problem and gather the information needed for the rest of the project. The final stage of this phase was to define the requirements for the new product. The second phase started with the development of concepts that could fulfill the requirements. Through extensive screening and evaluation of the concepts three concepts were chosen to further development. In the third phase these concepts were developed further and re-evaluated resulting in one final concept. The fourth phase of the project was to build prototypes to use for testing, based on the result of the tests the concept was re-designed and more tests were conducted. The fifth phase started when the tests were passed. In this phase the concept was further developed and the dimensions and the material of the parts decided. The final work that was done was to make a cost analysis to investigate if this type of product is something worth further development. The developed concept works as intended, however it will require more work before it can be manufactured. The objective of this Master of Science thesis was fulfilled; conceptual designs of an electrical push open was developed, a working prototype was built and the cost analysis and function description of the push open was generated. / När man designer nya möbler idag ligger stor fokus på att de ska göra livet lättare för kunden och på grund av detta har den elektriska öppnaren blivit utvecklad. I dagsläget används den framför allt i köket, både i lådor och dörrar. Funktionen hos en elektrisk öppnare är att användaren trycker på fronten av lådan eller dörren och då öppnas den automatiskt. Målet med det här projektet har varit att utveckla koncept för en elektrisk lådöppnare, bygga en enkel prototyp, utföra en kostnadsanalys samt att göra en funktionsbeskrivning till konceptet. Projektet var indelat i fem faser. Den första var att definera problemet samt att samla den informationen som var nödvändig för resten av arbetet. Det sista steget i den här fasen var att definera kravspecifikationen för den nya produkten. Den andra fasen av projektet började med att generera koncept på hur man kan öppna en låda elektriskt. Genom utförlig utvärdering av de framtagna koncepten valdes tre stycken att gå vidare med. I den tredje fasen av projektet vidareutvecklades dessa tre koncept och efter en andra utvärdering återstod bara ett. Den fjärde fasen av projektet var att bygga prototyper för att kunna testa koncepten samt att undersöka vad som behövde ändras. Den här processen itererades till dess att konceptet fungerade enligt planen. Den femte och sista fasen av projektet var att välja material och dimensioner av de ingående delarna i produkten. Som en sista del utfördes även en kostnadsanalys för att undersöka om den här typen av produkt är något som företaget ska gå vidare med. Det framtagna konceptet fungerade som det var tänkt, likvä kommer det ändå att krävas mer arbete innan man kan producera produkten. Målen med projektet uppnåddes; koncept var utvecklade, en fungerande prototyp konstruerades, och en kostnads analys och funktionsbeskrivning genererades.

Composite beams are frequently used in building, combining a steel beam with either a concrete-filled steel deck or solid concrete slab. To ensure proper composite action, shear connectors, typically in the form of headed shear studs, are utilized. Traditionally, the strength assessment of these headed shear studs is made using empirical design specifications that are based on push-out tests, which have been widely conducted and standardized over the years. However, the standardized push-out tests have short-comings, such as uneven slab bearing, slab buckling, questions regarding the distribution of load to each stud, etc. A study was conducted to evaluate and compare the existing push-out test setup with two alternative test setups. The study also aimed to examine the behavior of headed shear studs in composite beams having deck deeper the current allowable limit of 3 in., as specified by American Institute of Steel Construction (AISC) design specification. While the standard specification allows for steel decks with rib heights of up to 3 in., there are deck profiles deeper than 3 in. available in the market. Utilizing these deeper decks in composite beams offers several advantages, including faster and more cost-effective construction by reducing the number of beams required. This research therefore found that a major challenge in creating an alternative test setup involves eliminating moment at the interface between the concrete-filled steel deck and the steel beam. This moment leads to tension in the headed shear stud/stud group closest to the actuator, thus affecting the shear strength of the headed shear studs. Further, these headed shear studs have significant strength when used with 3.5 in. decks but further research is necessary. / Master of Science / Composite beams are widely used in building construction, combining a steel beam with either a concrete-filled steel deck or a solid concrete slab.

Using these deeper decks offers advantages such as faster and more cost-effective construction. One major challenge in creating an alternative test setup was eliminating the moment at the interface between the concrete-filled steel deck and the steel beam. This moment caused tension in the headed shear stud closest to the actuator, impacting the overall shear strength of the studs. Additionally, it was found that these shear studs show promising strength when used with 3.5 in. decks, but more research is needed to fully understand their capabilities. By exploring new test setups and considering deeper decks, this research contributes to improving the design and construction of composite beams, making them more efficient and reliable for future building projects.

Uppsatsen har som syfte att undersöka studenter vid Uppsala universitets syn på sin hembygd, deras nuvarande bostadsort och deras inställningar till att flytta tillbaka till hembygden. Detta görs med hjälp av kvalitativa respondentundersökningar i form av semistrukturerade intervjuer med studenter vid Uppsala universitet. Totalt har sex studenter deltagit i intervjustudien. Resultatet visar att studenterna har liknande uppfattningar av sin hembygd trots att de kommer från vitt skilda platser i Sverige. Hembygden ses som liten vilket har både positiva och negativa attribut. De har även en enhetlig uppfattning av den nuvarande bostadsorten Uppsala vilken ses som en plats som passar väl in i deras nuvarande livssituation. Respondenterna har skapat nya sociala nätverk i Uppsala och säger sig trivas bra i staden. Detta påverkar deras inställningar till att flytta tillbaka till hembygden då det i nuläget anses vara en större förlust att återvända eftersom det kan medföra att det nya sociala nätverket som skapats i Uppsala skulle försvinna. Deras livssituation i dagsläget anses inte heller vara kompatibelt med livet i hembygden. I samtliga intervjuer framgår det att respondenterna för närvarande inte har några planer på att återvända till hembygden.

Syftet med denna studie är att med hjälp av kvalitativ metod få en förståelse till vilka strategier invandrare väljer att använda sig utav för att etablera sitt liv i ett nytt land. Frågeställningarna i denna studie är: Hur upplevs förändringsprocessen från flyktingskap till etablering i ett nytt samhälle? Vilka utmaningar upplever människor i dessa processer?

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / During high performance fighter aircraft manoeuvres, a fighter pilot may be exposed to a physiological phenomenon known as the “Push-Pull Effect” (reference (ref) [1]). This effect will alter the pilot’s homeostasis whereas blood flow to the brain will be increased during low negative normal acceleration (-Gz) and suddenly decreased during positive normal acceleration (+Gz). It has been hypothesized that this effect can lessen the Gtolerance of the human body thereby making the subject more susceptible to G induced Loss of Consciousness (G-LOC) (refs [2], [3] and [4]). G-LOC is not a desirable state for a pilot in a high performance aircraft such as a CF-18. To better understand and study the Push-Pull Effect on a fighter pilot, the Aerospace Engineering Test Establishment (AETE) and the Defence and Civil Institute of Environmental Medicine (DCIEM) produced an In-Flight Research (IFR) Program sponsored by the Canadian Forces (CF). The aim of this program was to measure the physiological response of relaxed test subjects, unprotected by a G-suit, when exposed to the Push-Pull manoeuvre in flight. This IFR would validate the centrifuge data and confirm that the Push-Pull Effect can occur in flight. This paper will present the instrumentation, design, telemetry system and installation methodology utilized to perform experimental physiological research on a high performance, ejection seat equipped fighter aircraft (CF-18). Also, preliminary results on the Push-Pull Effect, obtained through this IFR Program will be presented.
