Projektets syfte var att effektivisera en flaskhalsstation på Dynapacs monteringslina av vältar. Dynapac tillverkar vältar för olika typer av underlag. En vält är en maskin bestående av en eller två valsar som vibrerar och packa underlaget som den kör på, exempelvis asfalt. Arbetets resultat innebär produktionseffektivisering av produktionsflödet hos Dynapac. Dynapac upplever att stationen där sammankoppling av valsarna till välten sker är en flaskhals för flödet. Anledningen till detta beror på att sammankopplingen sker vid sidan av linjen på ett specifikt monteringsbord, vilket resulterar i att många onödiga lyft krävs. För att minimera tiden så mycket som möjligt så är en ny monteringsmetod vid sammankopplingen nödvändig. Olika koncept tas fram och sedan poängsätts varje koncept där det koncept med högst poäng väljs och vidareutvecklas för att anpassas mot bland annat riskanalysen. Vid framtagning av de olika koncepten tas det hänsyn till den kravspecifikation som vi tillsammans med Dynapac tagit fram. Dynapac värnar om sina anställdas hälsa vilket medför att det ligger stort fokus kring säkerhet och ergonomi vid framtagning av den nya monteringsmetoden. Rapporten omfattar även en kort beskrivning av Scania i Oskarshamn och deras montering av lastbilshytter. Hos Scania sker montering på ett liknande sätt som hos Dynapac. Hållfasthetsberäkningar och ritningar för det valda konceptet tas fram. Ritningarna till det valda konceptet hittas bland bilagorna. / The purpose of the project was to streamline a bottleneck station on Dynapac's mounting line of rollers. Dynapac manufactures rollers for different types of groundwork. A roller is a machine consisting of one or two rollers that vibrates and pack the groundwork on which it drives, for example asphalt.The result of the work involves production efficiency of Dynapac's production flow. Dynapac finds that the station where you interconnect the rollers to each other is a bottleneck for the flow. The reason for this is because the interconnection occurs next to the line on a specific mounting table, resulting in many unnecessary lifts is needed. In order to minimize time as much as possible, a new method of interconnection is required. Different concepts are developed and then each concept is scored where the concept with highest points is chosen for further development. When developing the different concepts, consideration is given to the requirement specification that we have developed together with Dynapac. Dynapac protects the health of the employees, which means that there is a lot of focus on safety and ergonomics when developing the new assembly method. The report also includes a brief description of Scania in Oskarshamn and their assembly of truck cabins. This is a company where assembly takes place in a similar way to Dynapac and a comparison of the companies is made.Strength calculations and drawings for the chosen concept are made and the drawings are included in the annexes.

<p>Lead (Pb) is one of the most harmful and most abundant neurotoxins in the environment. Despite the extensive movement made to eradicate toxic levels of Pb in the environment, children, predominately in lower socioeconomic areas, are still exposed to varying levels of Pb. Human studies suggest that Pb exposure leads to altered drug consumption in adults by altering underlying neural mechanisms, specifically dopamine (DA) activity. However, there is limited research on this at blood Pb levels below 10 μg/dL, levels often seen in children growing up in neighborhoods located in old industrial and urban areas. To model how early-life low-level Pb exposure effects DA-dependent behaviors associated with addiction in adulthood, we used C57BL/6J mice. Litters were weaned at PND 21 and assigned to either a three-week history of 30 parts per million (ppm) Lead (IV) Acetate exposure or a control condition of 0 ppm Pb in DI drinking water. After the Pb exposure period, mice were switched to regular tap water until they reached adulthood. Afterward, separate animals were tested in one of three experiments: two-bottle choice alcohol preference drinking, alcohol-induced behavioral sensitization (EBS), and cocaine-induced behavioral sensitization (CBS). In experiment 1, our hypothesis was met, and both male and female mice with a prior Pb exposure displayed significantly higher alcohol intake and preference scores over the three-week period than control mice. In experiment 2, there were no differences in EBS and no evidence of EBS in any of the groups. However, there was an increased acute response to 2.0 g/kg EtOH in the Pb-exposed chronic group as compared to the control animals. Lastly, in experiment 3, Pb-exposed animals in the chronic cocaine group were more sensitive to the effects of cocaine (10 mg/kg) across days than the controls, both the acute cocaine groups and both saline control groups. Thus, with these experiments, we concluded that low levels of developmental Pb exposure might be targeting DA in the reward pathway, which is essential for alcohol intake and drug sensitization.</p>

In this Diploma Thesis the recycling of the PET bottles in the company PETKA CZ, a.s. is under focus. Thesis describes the Italian technology AMUT designed for physical recycling of the PET bottles. The primary goal is the quality of the final recycled product, PET flakes, particularly in the context of undesirable admixtures such as PVC, other polymers and impurities. Due to the deteriorating quality of the PET flakes the equipment Polymer Separation System Purifier N 1024 has been tested, which had significantly reduced admixtures in PET flakes. As it turned out, the current procedures for solving problems with the PET flakes quality are no longer sufficient.

Bakgrunden till examensarbetet var att vårdpersonal ska arbeta för att främja amning och för detta arbete behövs tydliga riktlinjer. Syftet med examensarbetet var att beskriva och jämföra omvårdnad och amningsutfall hos ammande barn som inte gick upp i vikt under sina första levnadsveckor. Metoden för arbetet var en retrospektiv journalgranskningsstudie där ett extraktionsprotokoll användes för att komma fram till resultatet. I studien inkluderades totalt 144 barn som vårdats inneliggande på barn- eller neonatalavdelning under perioden juli 2016 till juli 2019. Resultatet från studien visade att de flesta barn tillmatades med bröstmjölk och modersmjölksersättning via antingen bröst eller ventrikelsond samt att andelen barn som helammade var låg. Vidare visade studien att faktorer som minskade oddsen för helamning i samband med utskrivning var tillmatning med nappflaska, användande av modersmjölksersättning eller om barnen om barnets kön var en pojke. Slutsatsen var att barnen i första hand bör tillmatas via ventrikelsond då behov av tillägg utöver amning finns och att bröstmjölk bör vara förstahandsval vid tillmatning eftersom det främjar den fortsatta amningen. Barnsjuksköterskans roll för att främja amningen är att ge en god omvårdnad av barnet och fngera som ett stöd för mamman.

Nachdem Heinrich I. im Jahre 936 verstorben war, wurde an seinem Grab in Quedlinburg ein weltliches Frauenstift gegründet, dessen erste Äbtissinnen Töchter und Schwestern der ottonischen Kaiser waren. Unter diesen wurde es Tradition, das Osterfest wenn möglich am Grab des Vorfahren zu begehen, und auch nachfolgen-de Adelshäuser folgten diesem Brauch. Die mitge-brachten Geschenke bereicherten über die Jahrhunderte den Stiftsschatz und zeugen noch heute von der Bedeutung des Stiftes zu seiner Blütezeit.

OBJECTIVE: This study was conducted to compare the relative influence of the socioeconomic status of both mothers and fathers on feeding method and cosleeping. METHODS: The time and method of feeding and sleeping were recorded in a log during the 4th-week postpartum and analyzed according to the parental Hollingshead Index of Social Position in 33 families with their first newborn. RESULTS: The effect of socioeconomic status on feeding and sleep was parent specific. Low socioeconomic status of the mother, but not the father, was associated with cosleeping (t ≤ 2.39, P < .01); whereas, a low socioeconomic status of the father, but not the mother, was associated with bottle-feeding rather than breast-feeding (t ≤ 1.94, P < .05). CONCLUSIONS: Socioeconomic status of the parents differentially affects neonatal care. Programs to increase breast-feeding rates would be most effective if designed for and aimed at the fathers.

Background: Previous studies have demonstrated that breastfed newborns spend more time awake than bottle‐fed newborns, breastfeeding mothers have more fragmented sleep than bottle‐feeding mothers, and mother‐newborn sleeping arrangements may affect the sleep/wake pattern of mother‐newborn pairs. Objective: To address the unsolved question of whether there is an interaction between type of feeding and sleeping arrangements that affects postpartum sleep during the 4th postpartum week. Design: Correlational, two‐way design using feeding method and location of newborn at night as independent variables, and sleep patterns as the dependent variables.Setting: Patient's home during 4th week after giving birth. Patients/Participants: First‐time mothers and their newborns (n = 33). Main Outcome Measures: Amount of total sleep, amount of night sleep, number of night awakenings, and number of sleep periods in 24 hours using a modified version of the self‐report sleep instrument by Barnard and Eyres. Results: Breastfed newborns had less total sleep per day than bottle‐fed newborns, and breastfeeding mothers had more sleep periods in 24 hours than bottle‐feeding mothers. Breastfeeding mothers slept more than bottle‐feeding mothers when co‐sleeping, but bottle‐feeding mothers’ sleep was unaffected by location of newborn. Average total sleep for 4‐week‐old newborns was about 14 hours daily. Conclusions: More sleep was obtained when breastfeeding mothers slept with the newborn. Methods or devices that allow breastfeeding mothers and newborns to sleep next to each other in complete safety need to be developed.

One of the major remaining question about Mars is its habitability - if the requirements necessary to allow for life are presently fulfilled. One of the most relevant ingredients for life, as we know it, is water. Indirect evidence of transient liquid water on Mars has been retrieved from both rover [Martín-Torres et al., 2015] and orbiter [Ojha et al., 2015]. [Martín-Torres et al., 2015] inferred the existence of an active water cycle, driven by chlorate and perchlorate salts, which are commonly found on the Martian surface, and absorb atmospheric water to form stable hydrated compounds and liquid solutions. This happens through a process called deliquescence (absorption of moisture from the atmosphere by the salts and dissolving into a liquid solution). One of the goals of HABIT is to confirm the hypothesis about the water cycle on Mars. HABIT will record the behavior of a selection of salts on Mars, and will also record Martian environmental conditions (UVdose, air and ground temperatures). The Field-Site Prototype for HABIT (FSP-HABIT) was the first prototype of HABIT deployed during field-site campaigns. Three campaigns took place during summer 2016: First, a short preparatory campaign in Abisko, Sweden, was carried out. The second campaign took place in Iceland, within the EU COST Action TD1308 ORIGINS (Origins and evolution of life on Earth and in the Universe), and the third campaign was conducted within the NASA Spaceward Bound India Program in Ladakh. After providing the corresponding background on the mission framework and the scientific background, this document covers the mechanical, electrical, and software design of the instrument. Afterwards, the steps taken to test the instrument and their results are covered, followed by a rating of the instrument and ideas for future improvements. Instruments like FSP-HABIT will enable the characterization of hygroscopic salts by their conductivity as liquid brines are good conductors, hydrated salts are poor conductors, and dehydrated salts are insulators. During the field-site campaigns, the measurements of FSP-HABIT were used to characterize the near surface environment by its temperature, pressure and relative humidity. Now, these measurements are available for comparison with microbiological studies of the water, ice and soils to characterize the habitability of the explored site. The lessons learned while designing and building FSP-HABIT can be used to inform the development of further prototypes for space missions such as HABIT. / Habitability, Brines, Irradition and Temperature (HABIT)

Conditionner les produits alimentaires, pharmaceutiques et cosmétiques pour les conserver et les transporter a toujours été une nécessité pour des hommes à la fois consommateurs et commerçants. Cette étude, qui relève à la fois de l’histoire et de l’archéologie, souligne le rôle majeur joué par le verre, en Provence, au XVIIIe et au XIXe siècle, comme mode de conditionnement des marchandises de qualité. Depuis l’Antiquité jusqu’à nos jours, les produits de luxe, vins fins, huiles surfines et parfums sont protégés et mis en valeur par leur emballage en verre. Il est le matériau idéal car il possède toutes les qualités physiques et chimiques pour devenir fonctionnel et esthétique. Lorsque la Provence se lance, dans les premières décennies du XVIIIe siècle, à la conquête marchande des espaces maritimes, elle bénéficie d’une économie fondée sur la transformation d’agro-alimentaire local ou importé. L’industrie des emballages prend alors un essor considérable en Provence en lien avec cette économie. Les contenants en verre vont ainsi s’exporter à travers le monde, par bateau, grâce à l’action conjuguée de facteurs favorables : le rayonnement international du port de Marseille ainsi que les progrès techniques liés à l’adoption d’une nouvelle source d’énergie, le charbon. Influencée par l’exemple des autres régions, françaises et européennes, la verrerie provençale connaît une métamorphose notable qui conduit à l’abandon progressif des ateliers forestiers au profit d’une implantation portuaire. Sources écrites et iconographiques constituent une grande part de notre documentation complétée par les sources archéologiques. Elles sont liées principalement à la découverte et à l'étude récente d'épaves ainsi qu'à l'inventaire d'un mobilier diversifié, issu des collections publiques et privées. / Packaging food products, pharmaceuticals, and cosmetics to store them and transport them has always been a necessity for humans, both as consumers and merchants. This study, which deals with both history and archeology, highlights the major role played by glass, in Provence, in the 18th and 19th centuries, as a packaging quality method. Since Antiquity, and until the present day, luxury products, fine wines, delicate olive oils, and perfumes have been protected and emphasized through their glass packaging. It is the ideal material because it has all of the necessary physical and chemical properties to become functional and aesthetic. When Provence set out, in the early decades of the 18th century, in merchant conquest of the seas, it had an economy based on the transformation of local or imported agricultural goods. The manufacture of packaging then saw a considerable rise in Provence tied to this economy. Glass containers were then exported throughout the world, by sea, thanks to the combined action of favorable factures: the international reputation of the port of Marseille as well as the technical progress tied to the adoption of a new energy source : coal extraction. Influenced by the example of other regions, both French and European, Provencal glassworks underwent a notable metamorphosis which led to the gradual abandonment of forest glasshouse for port locations. Written and iconographic sources constitute a large part of our documentation supplemented by field sources. These are mainly tied to the discovery and recent study of shipwrecks as well as the survey of a diversified archeological inventory, derived from public and private collections.
