This paper considers the effects of intermittent injection of a liquid jet or spray on the initial break-up and mixing of one fluid with the surrounding ambient fluid. The aim of the analysis is to describe the physical process and indicate the mechanisms that control the mixing under different flow conditions (time-dependent injection and its frequency relative to the time scales of the flow) and
The breakdown of the ratification process of the EU constitution was in Sweden blamed on a lack of a debate concerning European issues. The constitution can be seen as the best and latest, but in no way the only, example of this problem. The breakdown can also been seen as proof of a larger legitimacy crises within the EU. The aim of the study is to determine whether or not there really was of lac
I oceanerna finns ett system av vulkaniska ryggar, där ny oceanbotten bildas genom intensiv vulkanism. Svarta eller vita lösningar skjuter med hög hastighet ut från skorstenar, som kan vara flera meter i diameter. Upptäckten av dessa heta källor för 30 år sedan var av stor betydelse för till exempel biologin: man hittade levande organismer vid skorstenarna. Dessa kan överleva trots det höga tryckeCirculation of hot hydrothermal fluids in fractures and faults of the oceanic crust is driven by temperature and pressure gradients. Fluid discharge is focused to vertical structures, black or white smoker chimneys on the seafloor. Hydrothermal vent temperatures should hypothetically be directly related to water depth. The boiling point of seawater increases with depth and ends at the critical poi
The purpose of this project was to reduce the production cost of the drive unit from AB Ph. Nederman & Co product Flowline with 50 % to make it more competitive, and the result is this report as well as a fully operational prototype. During the process I have looked into all of the functions of the existing product and have tried to improve them. The function which I have put most time and eff
Educational investments are made with the expectation that the acquired skills and knowledge will be applied on the labour market. Matching education and occupations lead to lower unemployment and vacancy rates and higher productivity and wages, but several imperfections of the labour market hinder the matching process. Education-occupation mismatch has been found to be positively linked with the
Kvicksilver, Hg, är ett farligt grundämne i miljön då Hg är ett flyktigt ämne. Hg blir farligt för oss människor om det ansamlas i kroppen i form av metylkvicksilver och kan orsaka skador på nervsystemet, njurar och fortplantningsorgan mm. Kvicksilver förs in i vår närmsta livsmiljö i allt större omfattning genom industriprocesser; vanligast är då förbränning av kol och användning i lampor, vulkanMercury is a a heavy metal and its presence in our environment constitutes an health-hazard for example in the form of methyl-mercury. Therefore, it is important to construct sensors to detect this pollutant. Research is also being performed on developing optical sensors and mercury can be detected through a range of methods, from point monitoring using Zeeman absorption to 3-D scanning of the atm
The declining number of conceptual articles, particularly in psychology and marketing (P&M), represents a key concern for the continued advancement of the body of knowledge. Proposition-based works, a key conceptual article subtype, offer theoretical propositions that introduce new concepts and theorize regarding their specific theoretical associations. However, relatively few guidelines for t
Importance: Although highly effective disease-modifying therapies for multiple sclerosis (MS) have been associated with an increased risk of infections vs injectable therapies interferon beta and glatiramer acetate (GA), the magnitude of potential risk increase is not well established in real-world populations. Even less is known about infection risk associated with rituximab, which is extensively
Purpose – The purpose of this paper is to provide a cohesive overview of the available self-service and customer value literature, identify customer value in self-service kiosks (SSKs), and analyze this value from the customer experience perspective.Design/methodology/approach – The study comprises a systematic literature review of available works on customer value.Findings – The paper presents co
The value problem for knowledge is the problem of explaining why knowledge is more valuable than mere true belief. The problem arises for reliabilism in particular, i.e., the externalist view that knowledge amounts to reliably acquired true belief. Goldman and Olsson argue that knowledge, in this sense, is more valuable than mere true belief due to the higher likelihood of future true beliefs (pro
The industrial and information revolutions that took shape in the British and Anglo-American empires, respectively, and that are linked in time and space by a westward expansion of capital, have both been justified and referred to as unavoidable and inescapable processes. Thus, they have been understood more as revelations of nature and less as products of a particular and historical society. Karl
Användningen av Artificiell Intelligens har ökat de senaste åren och många arbetsgivare väljer att integrera AI i rekryteringsprocessen i syfte att vara kostnads- och tidseffektiva. Men användningen av AI medför betydande nackdelar såsom oavsiktlig diskriminering. Uppsatsen syftar till att undersöka den rättsliga reglering inom diskrimineringsrätten när AI används i rekryteringsprocesser. Vidare k
The airline industry is undergoing hard time after the deregulation. Incumbents are facing increased competition from the new entrants- low cost airlines and try to keep their market share, which is mainly composed of business travelers to themselves. At the same time low cost airlines by providing low cost, point-to-point services try to compete with incumbents. Strategies of both incumbent and l
The Pan-Tilt-Zoom (PTZ) camera is a type of camera that covers large areas, up to 360°, in addition to zoom. Some of these cameras are susceptible to tampering, which means that an additional angle measurement feedback is necessary to detect such attempts. This thesis has evaluated the possibility of using MEMS-based IMUs to solve this problem. An advantage of such a system over other solutions, s
To ease railway traffic between countries in Europe, EU have decided that a new common signalling system should be implemented. This new signalling system is ERTMS, which is a shortening for European Rail Traffic Management System. Beside to ease traffic between countries, ERTMS can improve the level of safety and increase capacity on the railway network. The implementation of ERTMS amount a major
När föräldrar till barn i vårt samhälle blir oense och inte på egen hand kan lösa frågor om vårdnad, boende och umgänge träder vår rättsliga reglering in för att reda ut den konflikt som råder. Regleringen avseende vårdnad, boende och umgänge finns i 6 kap. FB. När en konflikt mellan föräldrar presenteras för socialnämnden eller tas upp i allmän domstol fyller de civilrättsliga reglerna kring vårdThe regulation concerning custody, residence and access are provided in the Swedish Parental Code Chapter 6. When a conflict between parents is presented before the social welfare committee or the general Court, our civil law regulation fills a controlling function as well as a conflict resolution function. Our social welfare committee or our Courts shall ensure that all decisions concerning cus
This master thesis was a project in cooperation with Höganäs AB. The aim was to increase the apparent density (AD) of two biomass chars, by three different agglomeration methods. The reason for the investigation is that biomass char could be used as a reducing agent in the sponge iron process at Höganäs AB. The goal was to exchange anthracite in the reduction mixture to agglomerated biomass char.
This thesis explored the possibility of a techno-feudal reframing of gig work. Previous researchers and theorists have frequently framed gig work within capitalist frameworks, like platform capitalism and piece rate wages, despite gig work’s odd similarities to the feudal organisation of work. Scholars like Durand have pointed out similarities between the digital economy and feudalism without
