Idag äger drygt 7 miljoner svenskar någon typ av värdepapper. Dessa handlas av två typer av investerare, den aktiva och den passiva. Den aktiva investeraren köper och säljer sina värdepapper mer frekvent för att dra nytta av dess upp och nedgångar, jämfört med den passiva investeraren som köper värdepappret på lång sikt.En aktiv investerare analyserar ständigt marknaden och dess utveckling, försöker utläsa historiska mönster för att förutspå hur framtiden kommer att utveckla sig. Att studera historiskt kursdata för att förutspå framtida mönster kallas teknisk analys . Två vanligt förekommande analysmetoder inom teknisk analys är glidande medelvärde och Relative Strength Index.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Breakfast and cognition from a youth perspectiveAuthor: Linn Kruse and Anneli HulldinSupervisor: Anna WinkvistExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 26, 2014Background: Breakfast as an influencing factor on cognition and is often on the table for discussion in society. A lot of research has been done about how omitting breakfast affects adolescents and their short time cognition. Cognition is complex as a concept and is measured in different ways and the existing research in the area often compares different types of breakfasts instead of the difference between eating and omitting breakfast.Objective: To evaluate the scientific evidence for an association between adolescents? breakfast eating and short time effects on cognition in adolescents.Search strategy: To find relevant articles a systematic literature search was made in the databases PubMed, Scopus and Cochrane. Search terms that were used were: children, young adults, adolescents, cognition, and breakfastSelection criteria: Ages 12-20 years, measures cognition, RCT, studies comparing breakfast eating with omitting breakfast, human studies, language English or Swedish, no sick adolescents or adolescents with diagnosis.Data collection and analysis: Two original articles met the inclusion criteria and were reviewed by the SBU audit template for RCT studies.

Syfte: Syftet var att finna skillnader och samband i self-efficacy (SE) ? med avseende på typ av artroplastik, kön och ålder ? inför två förflyttningar. Detta för att se vilka patienter som kan vara i större behov av att stärka SE postoperativt.Metod: Studien gjordes på inneliggande patienter som genomgått en höft- eller knäartroplastik. Ett för undersökningen framställt frågeformulär undersökte de 117 deltagarnas SE inför att sätta sig upp på sängkanten samt gå med hjälpmedel. Deltagarna skattade SE inför förflyttningarna första eller andra dagen efter operationen.Resultat: Deltagare som hade genomgått en knäartroplastik skattade signifikant högre SE inför att sätta sig upp på sängkanten än de som hade genomgått en höftartroplastik.

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

AbstractThe purpose of this essay was to determent if the authors? idea to replace a personal trainer with a training program, which is provided by software, is viable and if there is a market for such a product. The method that was used, included eight people who enrolled in a training program which were designed by the authors in Microsoft excel. The programs were based on principals of periodization, and included the phases: anatomic adaptation, hypertrophy, maximum strength and muscle definition. The training program was personal and based on individual goal setting.

Gross motor skills among Swedish pupils. An overview of functional motor abilities among Swedish children and adolescents.IntroductionPhysical Education (PE) teachers in Sweden have noticed that pupils are getting worse in their ability to manage gross motor skills and in their aerobic practice. The gross motor skills and coordinative skills are the solid ground for sports and other health activities. If not developing their gross motor skill children tends to avoid taking part in games and sports. The benefits of sports and outdoor activities such as social and health benefits can therefore be missed.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

This report describes the master thesis project ?Weight Optimization of a Composite Chassis for a Multimodal Lightweight Vehicle? which is a part of the Master program in Naval Architecture and a part of a research project at the Centre for Naval Architecture, KTH. Demands on smart and energy efficient transport solutions are continuously increasing. In the Stockholm region the citizens are expected to increase with 25% and the road vehicles with 80% until 2030, putting high demands on the traffic system. Using a small multimodal vehicle deals with this problem and uses both the land and waterways for transportation.

Introduktion/Syfte. Intresset för och användandet av adhesiv cementering av keramiska material har ökat under de senaste åren. Detta har lett till ett ökat intresse att kunna jämföra olika studiers resultat med varandra och därmed har även intresset för att utveckla internationella standarder inom forskning ökat. Syftet med denna studie var att jämföra den adhesiva bindningsstyrkan mellan ett laboratorieframställt material innehållande kvartsmjölsförstärkt epoxyresin (Sipoxy), med emalj och dentin. Detta för att avgöra om Sipoxy kan användas som en standardiserad ersättning istället för tänder i in vitro studier som utvärderar bondade keramiska rekonstruktioner. Material & metod.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

Syfte: Sammanställa och granska studier gällande postoperativ behandling vid ruptur av ligament patella. Detta för att beskriva effekt och kvalitet på studier om postoperativ behandling.Metod: En beskrivande litteraturstudie valdes som design, med sökorden: patellar ligament, patellar tendon, rupture, knee injuries, surgery. Av totalt 1240 träffar valdes 13 relevanta artiklar publicerade mellan 1999-2013 efter sökningar i databaserna PubMed, PEDro, COCHRANE, SCOPUS, CINAHL, SPORTDiscus och AMED. Artiklarna kvalitetsgranskades enligt PEDro scale.Resultat: Två postoperativa behandlingar beskrevs, tidig och sen mobilisering. Antingen placeras knäleden i ett stabiliserande knäskydd som till en början låser knäleden i full extension eller så påbörjas tidig mobilisering av den opererade knäleden.

This study was conducted on a property with a thinning machine team. The purpose was to investigate in which machine, the harvester or the forwarder, that caused most damage to the trees in six different stands. Different factors, related to the damage frequency in the stands, were checked out. For example: basal area per hectare, thinning strength, tree diameter and the rate of production. The harvester drivers were also interviewed about how, when and why stem damages occur and how to minimize them. The study stated that 4.3 percent of the trees were damaged. Out of these 88 percent was caused by the harvester and the rest, 12 percent, by the forwarder..

The project is a thesis which intends to strengthen the form language and increase the user friendliness of an International Moth. This is a single handed dinghy with only one sail. It sails on two hydrofoils and receives a very high speed compared to its size, and are therefore often referred to as ?the Formula One on water ?. The result is a new concept where the aerodynamic forces have been used to stabilize the boat and relieve the hydrofoils.

The present study examines a new production line of glue-laminated wood (glulam). The glulam is produced from non-planed boards of spruce, which also is convex, that is pressed together with high pressure during the gluing. According to a economic calculation, the material has a economical potential mainly on account of the absent planning. The study mainly found out that the shear strength of the material tolerated the demanded values in standard SS-EN 386, but the delaminating values did not. Since there are more areas to be studied around the material, the prospect to achieve the right delamination values is seen as positive..
