Steloperation av nacken vid whiplashrelaterade besvär : single-subject studie av två patienter

SAMMANFATTNING Bakgrund: Whiplashrelaterade besvär är vanligt förekommande efter en bilolycka. En behandling för dessa patienter är steloperation av övre nackkotpelaren. Dock finns lite forskning kring hur detta i allmänhet och i synnerhet ur ett beteendemedicinskt perspektiv kan påverka en patient. Syfte: Var att utvärdera om steloperation av övre nackkotpelaren hade effekt för två patienter med långvariga whiplashrelaterade besvär, avseende vissa beteendemedicinska aspekter innehållande psykologiska och kognitiva funktioner. Metod: Experimentell single?subject studie som innehåller baslinje-, interventions- och uppföljandemätningar (A1-B-A2 design).

Inneluftsventileradekryprumsgrunder : en utvärdering av två tillverkare

This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.

OLED : Evaluation and clarification of the new Organic Light Emitting Display technology

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Finns det någon cross-overeffekt mellan statisk och dynamisk uthållighetsträning av bålmuskulaturen, och hur påverkar de olika träningsformerna resultatet på ett bålstabilitetstest?: En studie med single subject experimental design

Bakgrund: Bålträning kan användas vid prevention, behandling samt för att öka prestationsförmåga. Vilken typ av bålträning som är lämpligast för de olika ändamålen är dock fortfarande oklart, vilket till viss del beror på brist på tydliga definitioner inom området. Mot bakgrund av specificitetsprincipen inom träningslära och bålmuskulaturens olika indelningar och dess muskelfysiologi, vill författarna undersöka om en cross-overeffekt kan uppnås mellan två olika typer av uthållighetsträning, liksom träningens effekter på bålstabilitet. Syfte: Syftet var att beskriva observerade och mätbara effekter av dynamisk bålträning på statisk uthållighet i bålmuskulaturen, och omvänt, samt de observerade och mätbara effekterna av de respektive träningsformerna på resultatet av ett bålstabilitetstest. Metod: Studiedesignen var single subject experimental design (SSED).

OSSemellan - Oro, stress och sömnproblem: En indikerad preventiv insats för ungdomar

I dag lider ca 25-35 % av skolungdomar av psykisk ohälsa. Tidigare forskning har visat att denna ohälsa beror på att ungdomar sover alltför lite, vilket i sin tur associerats till en ökad användning av sociala media. Orsakssambanden är emellertid oklara och varierar mellan studier. Av den anledningen genomfördes en enkätstudie på gymnasielever, för att ytterligare belysa hur sambanden ser hos svenska ungdomar.I undersökningen användes två frågeformulär bestående av en reducerad version av KASAM, ett sömnformulär, samt frågor angående sociala media.I studien deltog 51 elever (M: 18.0 år, SD 0.35), varav 22 kvinnliga och 28 manliga elever i ÅK 3. Resultatet visade att cirka hälften av eleverna (49 %) ansåg sig sova signifikant kortare tid än vad de önskade (p<0.0001).

Snabb och säker roaming i WLAN

This thesis investigates how Ericsson AB should do to achieve fast and secure handover when roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. The premise was that they wanted a standardized way of handling the roaming issue. At the outset the 802.11F standard looked like a good alternative (in fact the only standardized alternative).

Tjänsteföretag i samarbete : En studie av små kunskapsintensiva tjänsteföretags utveckling vid samarbete

AbstractBachelor Thesis, School of Economics at Vaxjo universityProgram: Enterprising and Business Development, EBD 362, Spring 2006Authors: Jens Asp, Vivianne Holmer, Carl-Marcus WahlstromExaminer: Stig G JohanssonKeywords: Services, cooperation, collaboration, customer offer, knowledgeTitle: Service firms in collaboration ? A study of the development of small service firms in collaborationNutek presented numbers during year 2005 witched show that the Swedish service sector, for the first time ever, was greater than the industrial sector. The kind of firms that develop most is small service firms without employees. The topic of interest in this bachelor thesis is to study how this kind of firms can develop. There is a great number of strategic options for firms to choose.

Symbolisk dekoration : En studie av Järnspiralen som symbol under yngre järnålder.

When the Iron spirals investigated in this paper saw the light again no one looked at them as nothing more than decoration. It was first during the 2011 excavation in Old Uppsala that the symbolism of the items no longer could be ignored. The spirals of Old Uppsala lay along the walls of the great hall, which stood upon one of the human constructed plateaus in the area. The hall had been burned down and then cleared of all lumber. Then the iron spirals had been placed in the positions and then everything was sealed with a layer of clay.A study of the artifact began with the purpose to contextualize and interpret the iron spiral.

Skydd mot yterosion i slänter av finmorän

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

Fågel fisk eller mittemellan?

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.

Agenda-setting, policyprocess & Kingdon : ? En studie av restaurangmomsen

What attribute affects salience on a political agenda? How come some reforms are implemented while others are not? These are essential and central questions for our society. Our society, our democracy and our everyday life are dependent of these factors; communication is the condition. In the 2011 budget from the Swedish conservative government, the question of lowering the VAT on restaurant- and catering services was the single most debated reform. This was occasioned from 2009 when the European Union allowed, for the first time since Swedish entry in 2005, a lower VAT on restaurant services.

Effekten av högintensiv aerob träning på kognitiva funktioner hos friska unga vuxna

Inaktivitet har blivit ett stort problem i dagens stillasittande samhälle och stor vikt läggs på de intellektuella färdigheterna. Konditionsträningens positiva påverkan på de kognitiva funktionerna har under de senaste åren studerats och resulterat i ett flertal artiklar rörande ämnet. Den forskning som bedrivits har undersökt den kortsiktiga påverkan av kognitionen. Syftet med denna studie var att undersöka den omedelbara påverkan på de kognitiva funktionerna: resonemang, koncentration och uppmärksamhet efter högintensiv konditionsträning samt se om en ökad kondition förbättrade kognitionen hos friska unga vuxna. Syftet med undersökningen uppnåddes genom en kvantitativ single system experimental design studie där författarna gick in som deltagare.

Resurseffektivt bussprotokoll o?ver RS-485

This report describes the design and implementation of a multi-master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.
