To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
Skattning av biverkningar : Sjuksköterske- och patientuppfattning om behandlingsrelaterade biverkningar vid stamcellstransplantation.
A possible treatment for patients with lymphoma and myeloma is stem cell transplantation (SCT). SCT is preceded with cytostatic treatment. There are several side effects related to this treatment, for example fatigue, nausea, constipation/diarrhoea, pain, mucositis and loss of appetite. Aim: Investigate which side effects related to the treatment where most troubling after SCT and if nurse assessment and patient assessment differ. Methods: A quantitative empirical study with repeated measuring.
Vilken påverkan har fysisk aktivitet på lärande
ABSTRACTThe purpose of the study was to examine, from the point of view of former research findings, what impact physical activity had on learning. I chose to make an explorative/inductive research, to get as much knowledge as possible from the studied presentation of problem, not to limit myself to a specific research theory. The result proved, that school personal and student experienced many positive effects from daily physical activities. The pupils were more pleased. There was more piece and quiet in the classroom.
EN JÄMFÖRELSESTUDIE AV PLAST- OCH GLASHEMOCYTOMETRAR FÖR BERÄKNING AV BLODCELLER I VENÖST OCH KAPILLÄRT HELBLOD
Hematology-instruments that analyze blood cells can at specific cases
be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.
Inkludering i skolan : Men till vilket pris och för vems bästa?
Within special education, there is a big dilemma where some mean that school should include all pupils in the same school class, regardless of the students' needs for assistance, while others believe that students with special needs to be placed in small adapted groups where students have similar needs is to exclude pupils. While others argue that the inclusion can sometimes lead to exclusion. The aim is to investigate what meaning teachers and special education teachers gives the concept of inclusion in school and what consequences it entails in teaching. This study is based on a number of qualitative interviews of teachers and specialist teachers to obtain answer of the following questions.Has the concept of inclusion and integration the same significance and meaning according to those asked teachers, special educators and special educators?Which students should be included, according to those asked teachers, special teachers and special teachers?What is required to work from an inclusive perspective, according to the asked teachers, special teachers and special teachers?Perceive the asked teacher, special educators and special teachers some disadvantages of inclusion?Which students receive special education instruction in the schools were asked?Do the asked teacher, special educators and special teachers think that there is a school for all?The results of this study is that teachers and special instructors have difficulty indistinguishing the concepts and that they puts the same emphasis on inclusion as the integration, the students must adapt to school and not vice versa.
Företagsrekonstruktion : En rättslig analys av franchiseförhållandet vid en rekonstruktion
A company reconstruction is an alternative procedure, for companies in payment difficulty, to receivership. Those in any kind of relationship with the ailing company ends up in a dif- ficult situation at a company reconstruction, as in any case when someone is in financial difficulties. Not only is there a risk for the providers not to get paid, the costumers are also at risk if the reconstruction company does not fulfil their agreement. These kinds of rela- tionships are controlled by a contractual relationship. Therefore the regulation has to con- tain how to deal with these contracts when the ailing company no longer can fulfil its obli- gations of the contract.
Trådlös energiöverföring via elektromagnetisk induktion
This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..
Våga Vara Annorlunda?: En uppsats om hur produktengagemang och motivation påverkar inkongruent marknadskommunikation
To be seen is essential. Presently, the marketing of different well-known brands within the same product category is done with little variation. To marketing professionals, this creates an opportunity to market products in an unexpected way. The use of incongruent market communication and by creating a discrepancy between a well-known brand?s advertisement and brand scheme, which is already established in customers? minds, is one way to be different.
Koncentrationssvårigheter utifrån pedagogens perspektiv : Hur påverkas klassen och den enskilda individen?
Syftet med det här arbetet var att undersöka utifrån några pedagogers perspektiv hur koncentrationssvårigheter beskrivs samt hur elevers koncentrationssvårigheter påverkar andra elever/klassen. Jag valde att göra en intervjustudie, där jag intervjuade fyra pedagoger utifrån deras erfarenheter och upplevelser. Jag ställde frågor som berörde svårigheter och yttrande av koncentrationssvårigheter, de andra elevernas reaktioner samt påverkan på klassen.Resultatet av undersökningen visade att pedagogerna upplever att elever kan tycka att det är jobbigt och kan själva bli störda av barnet med koncentrationssvårigheter. Det framkom också att barnen runtomkring lär sig att hantera situationen genom att t.ex. ignorera.
Fallet Bosman - en kvantitativ studie om fotbollens förändring och den fria rörlighetens effekter inom EU.
In 1995 something happened that radically changed the European football. This was the arrival of the Bosman ruling, a decision made by the European Court of Justice which meant that players with an expired contract could change clubs for free and that the European Union's internal market including the free movement of labour was now a part of the European football. The effects of theBosman ruling are wildly discussed today. Many powerful people in the European football mean that football now is less competitive than before, that there are a small amount of teams that actually have the ability to win any trophies. This bachelor thesis is studying the effects of the competitive forces in football after the Bosman ruling as a case of the free movement in the European Union.
Internationalisering av tjänsteföretag : En undersökning av svenska träningskedjors internationalisering
The study aims to investigate Swedish fitness companies positioning and strategic choices when internationalising in the Scandinavian countries and what has influenced this choice. Furthermore, the corporate risk and what obstacles they encountered will be examined.The study was conducted as a qualitative study with a deductive approach. The results are based mainly on primary data from interviews, as well as secondary data.The fitness companies? choice of strategy in internationalisation depends largely on its concept and positioning. The main obstacles in the internationalisation process are lack of communication, language difficulties and regulations.
Improvements in milking management through imitation of calf behaviour
Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.
Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk
In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.
Självbestämmanderätt och inflytande : En studie om hur representanter från handikappföreningar, goda män och LSS handläggare diskuterar människor med funktionsnedsättnings rättigheter
This essay has a purpose to understand and investigate how disabled people, where the handicap imply difficulty to speak for one self, get the rights of self-determination and influence satisfied. Our purpose with this essay is to focus on how representatives from organizations, trustees and Support and Service for Persons with Certain functional Impairments- officials(abbreviated LSS after the Swedish title of the Act lag om stöd och service till vissa funktionshindrade), describe and discuss matters concerning the individuals? opinions and requests from within their respective position. We will with this as a base analyze how these three parties facilitate and meet the individuals? influence and self-determination.
