Kalkskaliga nannofossil är spår av mikroskopiska organismer som utvecklades signifikativt under och efter slutet av trias, vilket kan ha påverkat havskemin samt kalkbildning i haven. Coccoliter, nannoliter och kalkskaliga dinoflagellater är vanligen förekommande kalkskaliga nannofossil som påträffas i övre trias. Denna studie syftar till att kvantifiera och undersöka laterala variationer hos kalksCalcareous nannofossils are microscopic remains of organisms that diversified considerably in and after the Late Triassic, and which may have influenced seawater chemistry and carbonate production. Coccoliths, nannoliths, and calcareous dinoflagellate cysts are important parts of many calcareous nannofossil assemblages in the Upper Triassic. This is a quantification study of an Upper Triassic lime

Researchers agree that there exist a close connection between export, foreign direct investment and economic growth, still they do not agree about the causal relationships between them. Latin America has over the last decades faced several economic crises. However, the continent has also been characterised by emerging economies, increased globalisation and trade liberalisation where export, foreig

The data was analyzed by using thematic analysis, which enabled the identification of eight different themes. Results shows that participants described depression from several

This thesis is a qualitative study which intends to research how the Swedish climate change sceptic Facebook page Klimatbalans uses its platform and vast follower base to influence the public opinion about climate change science and politics. The purpose of the thesis is to gain a deeper understanding of Klimatbalans’ reasoning behind their climate change sceptic agenda, and how the Facebook page

This report presents measuring and identifications of the process in papermachine PM4 Gruvöns Bruk, Grums.
Our intention was, except the measuring itself, to improve, if possible, the system model now used for process control with an IBM 1710 system.
The measurings were accomplished during the last two weeks of February 1969, and included six series of about 2000 samples each using a sam

Many machines and robots working today in factories are programmed to perform the same task repeatedly. By observing the tracking error in each iteration of the same task it becomes clear that it is actually repetitive, even though disturbances from noise and possibly sligthly changing friction dynamics affect the response. The idea of Iterative learning Control D ILC E is to use the knowledge fro

Katalysatorer är viktiga komponenter i den kemiska industrin. Deras användning tillåter kemiska processer att ske på ett ekonomiskt och miljövänligt sätt, förutsatt att de är stabila och har bra aktivitet i den kemiska miljön där de tillämpas. Ett viktigt steg vid implementeringen av nya kemiska processer är alltså att utveckla lämpliga katalysatorer. Processen att utveckla sådana kan vara väldigtEstablishing a technically practical method to generate representative model catalysts for the use in characterizations and testing prior to catalyst implementation in chemical process units would allow for a more sophisticated understanding of the underlying catalytic mechanisms. As a step towards establishing such a method, generating non-agglomerated, spherical NiMo nanoparticles, with diameter

Reference signal is 163.84MHz, reference-spurs is -80dBc/-98dBc lower than main frequency. RMS

Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. Oily yeasts have several advantages in comparison to alternatives; their doubling

Although the EU has substantial influence over how and with what Swedish municipalities work, the national level still tends to be the point of departure for the EU cooperation and analysis thereof. This qualitative single case study intends to abandon that tradition through investigating the consequences of EU projects at the local administrative level. Due to a lack of earlier research about the

Denna studie har syftat till att undersöka den retoriska potential som hip hoppens lyrik, rap, skulle kunna besitta i klassrumssammanhang. Undersökningen intresserar sig för dess effektivitet som minnesstrategi men också dess potential som ett media att förmedla kunskap. Genom en övergripande analys av begreppen retorik och hip hop synliggörs detta och undersöks därefter genom autoetnografisk aktiThis study has aimed to explore the rhetorical potential that hip hope poetry, rap, could possess in classroom contexts. The study is interested in its effectiveness as a memory strategy, but also its potential as a media to convey knowledge. Through an overall analysis of the concepts of rhetoric and hip hop, this is made visible and then investigated through autoenographic action research. The r

Batterier möjliggör mer solel än elnätet tidigare klarat av En ökad andel solenergi i elnätet ställer nya tuffa krav på det befintliga nätet. I det här examensarbetet har möjligheten att undvika nätförstärkning genom att istället installera batterier på väl valda platser i nätet undersökts. Med hjälp av lösningen kan mer solel än nätet tidigare klarat av installeras. Historiskt sett har el produThis thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. This could enable faster integration of solar power and a reduced demand for

The paper examines the relationship between non-formal education activities and youth employability in the Republic of Armenia. A case study has been conducted in order to identify soft skills competitive in the labour market and see to what extent non-formal education increases youth productivity thus helping them get engaged in the job market. Another thing that the paper aims to study is the ro

Current land use change and habitat fragmentation have caused severe decline in bumble bee populations. In order to address this issue and plan future conservation measures and strategies for plant pollinator networks, it is important to understand their foraging behaviour. A few studies in the past have tried to understand foraging constancy in bumble bees. However, there is no clear information

Characterization of a gene associated with polar growth in Streptomyces venezuelae Bacteria display a variety of shapes which includes spheres, rods, spirals etc. This variety of cell morphology is determined by the cell wall and the cytoskeleton, and by mechanisms that control growth, cell division and cell wall synthesis for example in response to the surrounding environment. Streptomyces spp.

The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with a 180 deg turns under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase blade tip lifetime. Pin

Background Numerous subsets of patients with chronic lymphocytic leukemia display similar immunoglobulin gene usage with almost identical complementarity determining region 3 sequences. Among IGHV4-34 cases, two such subsets with "stereotyped" B-cell receptors were recently identified, i.e. subset #4 (IGHV4-34/IGKV2-30) and subset #16 (IGHV4-34/IGKV3-20). Subset #4 patients appear to share biologi
