Aktiefonder : Ett lönsamt investeringsalternativ?

Background: Mutual funds have become an important part of the Swedish deposit market. Savings in mutual funds add up to almost 20 percent of the households'assets. When the pension reform is carried out all employees are going to have savings both in mutual and bond funds. But only if the fund overperforms the market it is worth investing. Purpose: The purpose of this study is to explore if Swedish mutual funds have generated higher returns than market portfolio in the late nineties.

Värdehöjande tjänster att ta hänsyn till vid nyetableringar av träningsanläggningar : En kvantitativ studie baserad på beslutsprocessmodellen

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.

Frukost och korttidskognition ur ett ungdomsperspektiv

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.

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.

Effekten av hormonsubstitution hos äldre män med åldersrelaterad testosteronbrist: en litteraturgranskning

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).

Personlig träning på egen hand

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.

Allsidig rörelsekompetens hos barn och ungdomar : En kartläggning av skolelevers funktionella motorik

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.

En socialpsykologisk studie om organisationsvisionens betydelse för sociala relationer i arbetsvardagen

In this study, we have considered the impact the organization`s implementation of its vision of the psychosocial work enviroment has been for the relations between the employees. We have primarily relied on a hermeneutic approach to understand our empirical data, and when we have interpreted and made a socialpsycological analysis on our collected empirical data. We have used Smith´s Institutional Ethnography, Sheff`s Social bonds and Asplund`s theory of Social responsivity. To collect the empirical data we have combined quantitative and qualtitative methods and a textanalysis at a visiondocument in the aim of capture both the depht and the breadth of our chosen fields of study. The results we have found shows that the psycosocial work environment within the organization can be seen as interplay between individual and enviroment and between individuals as well and that this interaction is influenced by the organizational culture that is created by the organization`s political vision.

Biosensorsystem fo?r o?vervakning av vattenkvalitet

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.

Viktoptimering av ett kompositchassi till en multimodal lättviktsfarkost

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.

Förändring av olika fysiologiska parametrar vid styrketräning hos äldre

SammanfattningSyfte och frågeställningar. Syftet med denna studie var att på äldre personer studera olika fysiologiska parametrar före och efter en period på åtta veckor med styrketräning som utförs tre gånger i veckan. Frågeställningarna var: Hur påverkas statisk och dynamisk maximal styrka i främre lårmuskulaturen av styrketräning? Är det någon skillnad i resultat mellan koncentrisk och excentrisk styrka i lårmuskulaturen före och efter styrketräningsperioden? Är det någon skillnad i förändring mellan benstyrka uppmätt med isokinetisk teknik jämfört med uthållighetsstyrka och ett kort funktionellt benstyrketest? Hur påverkas maximal syreupptagningsförmåga registrerad via submaximalt cykeltest respektive vid pyramidtestet av träningsperioden?Metod. I studien deltog 20 generellt ej påtagligt aktiva män och kvinnor i åldrarna 66-79 år.

Optimering av sintrade kugghjul

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.
