This Independent work is about testing a method to create meaningful learning and a deeper comprehension in matter of basic hairdressing techniques. I got the idea for this method by reading literature related to my education to become a teacher for hairdressers, the new schoolreform and from my own experience of a teaching method that I saw an opportunity to develope. My teaching method was based on first teaching the pupils the basic techniques, and then give them an assignment were they were to find out their own final result by using a picture for inspiration. They were given an assignment description with certain frames but with freedom of choice how to get to their own final result. By making a job description and a headdrawing to show how the work should be done, and during the process try different ways to achieve the best result, my idea was that a deeper understanding and a feeling of meaningfulness would appear.The result shows that the pupils by freedom within frames experienced meaningful learning and thereby deeper understanding when it comes to basic hairdressing techniques.
Vätskor i indirekt energiöverförande kylsystem och deras potentiella inverkan på miljön
Syftet med studien är att kartlägga innehållet hos vätskorna i de indirekt energiöverförande kylsystemen och att uppskatta deras potentiella miljöpåverkan vid utsläpp. På vätskeprover från system 5 till 8, som är tagna i returledningen på köldbärare 1 i respektive system, har det uppmätts hög syrgashalt, konduktivitet och COD (chemical oxygen demand), vilket ger stor risk för nedbrytning och korrosion. Dessa systemvätskor borde avgasas eller bytas ut. Systemvätskan från system 3, 7 och 8 överskrider gränsvärdena för zink och nickel och de skulle ha toxisk/ - mycket toxisk effekt på vattenlevande djur och växter. Koppar, zink och nickel är nitrifikationshämmande vilket innebär att de påverkar det biologiska reningssteget vid avloppsreningsverket negativt ifall vätskan släpps ut till det kommunala avloppsledningsnätet. Det framgick utifrån den använda värderingsmallen att de sju största miljöaspekterna är relaterade till föroreningsvariablerna: COD (chemical oxygen demand), zink, syrgas, kväve, järn, nickel och pH. Miljöeffekterna uppträder i form av påverkan från metaller och utarmning av naturtyper, biotoper, arter etc.
En undersökning om följsamhet till basala hygienrutiner och kläder på en akutmotaggning : en kvantitativ observationsstudie
AbstractHygiene plays an important role in health care to prevent contamination. Their lack of application of the basal hygienrutinera is a major cause for the spread of microorganisms occurs. The purpose of this study is to examine how rules of basic hygiene and clothing followed in the emergency department a quantentative approach involving the observation was to collect data on this activity. The data collection went on for 1 week at the emergency room, where hospital staff including doctors, nurses and assistant nurses was observed. The study showed that staff at the emergency department did not fully comply to the rules for basic hygiene routines.
Effektiv sökning med Google: en jämförelse i återvinningseffektivitet mellan enkel och avancerad sökning
The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.
Geografisk presentation av statistik på Internet: Web Mapping
Arbetet som utförts består av två applikationer där båda presenterar information geografiskt på internet. Applikationerna har konstruerats i utvecklingsverktyget Visual Basic och med GIS-programvarorna MapObjects och MapObjects Internet Map Server. Den första applikationen som tillverkades är helt HTML-baserad (HTML är ett språk som används för att konstruera sidor på internet), vilket betyder att den fungerar som vilken sida som helst på internet, bortsett från att den kräver att en kartserver alltid har igång kartan i applikationen. Den andra har konstruerats med ActiveX. ActiveX är ett tilläggsprogram som fungerar tillsammans flera utvecklingsverktyg bl.a.
Processdatorsystem för tryckreglering
The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..
Avgång av lustgas från luftningsprocessen på Käppalaverket
The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.
Flygplansavisningens miljöpåverkan vid svenska flygplatser
The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.
Varför undervisa om Förintelsen? : En intervjustudie om hur historielärare i högstadietundervisar om Andra Världskriget och Förintelsen i samband medvärdegrundsarbetet
This is an interview- and literature study that discusses teaching about the Second World War and the Holocaust, while working with the basic values in grade 7-9.The purpose with this examination is to see how teachers of history in grade 7-9 choose to teach about the Second World War and the Holocaust, how they work to integrate the basic values in their education and whether the teachers? education can be sustained by the Swedish school curricula.In this study I?ve been doing qualitative interviews with five teachers of history in grade 7-9 from different schools. I have also perused the Swedish school curricula and read some literature and studies about different ways of dealing with the subject: the Holocaust.According to the central parts of the Swedish curricula, LGR 2011, the fields about the Holocaust and the 20.century World Wars are to be studied during grade 7-9. All my respondents in the study teach about this think that the most important thing with this complex time in history, is to give the students a deeper understanding for the time leading up to the beginning of the Second World War in 1939, and why the Holocaust actually took place.Regarding the work with the basic values, all the five respondents agree on the fact that, this subject shall permeate the entire work at school, all the time, every day, but that it?s absolutely essential while studying the Holocaust.

Effects of treatment with PiNO (Pulsed Inhaled Nitric-Oxide) on the metabolism in colic horses undergoing abdominal surgery.
The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.
Möjligheterna att ändra väckt talan i dispositiva tvistemål : En studie av 13 kap. 3 § RB
The purpose of this thesis is to investigate the plaintiffs and the defendant?s prospects to change their claims and pleas in optional civil actions and how the rules for the modifications of a suit are affecting the framework of the process. The plaintiff's general ability to expand and alter the claim is found in the chapter 13, 3 § of the Act of Procedure and the basic principle is that a claim is not to be changed. From this basic principle exceptions are allowed to claim another fulfillment or to expand the process with a claim for interest or other additional obligations. The plaintiff can also limit his or her claim or expand the claim with new legal foundations as long as the issue of the process does not change.
Guldlock och de tre björnarna, en saga utan familj : En intervjustuide med sex personer verksamma inom förskolan angående skönlitteraturens roll i verksamheten och behovet av icke-heteronormativ skönlitteratur
Literature is an important part of the daily activity in preschool and it is also a powerful tool for reinforcing different norms.The purpose of this study is to explore, through qualitative interviews, for what purpose pedagogues in preschool use literature in their daily activity and what needs these pedagogues see for non-heteronormativity literature. The study also relates the needs that pedagogues see with the basic values presented in the Swedish National Curriculum for preschool.Literature is used in preschool for a wide range of purposes including; enriching the language, getting familiarized with the written language, show diversity, reinforce norms on how to be a good friend, as a starting-point for discussion, working with a theme or to have a fun time.The needs that the pedagogues see for non-heteronormativity literature can be divided in to three categories namely there is always a need, there is only a need when somebody requires that kind of literature to identify themselves with or there is only a need when somebody is being discriminated because of not belonging to the heteronorm.The need for non-heteronormativity literature being there always corresponds with the basic values in the Swedish National Curriculum for preschool and the recommendation that the basic values are visible in the daily activity of the preschool. The other needs doesn?t correspond with this, but it matches other parts of the Swedish National Curriculum for preschool..
