"Den kemiska bekämpningen av skadlig lövskog har öppnat helt nya vyer för skogsbruket" : flygbesprutning med herbicider i Arjeplog 1953-1978

Attityden gentemot lövträd och lövskog i norra Sverige började förändras i mitten av 1900-talet. Tidigare var lövträden en resurs inom det agrara samhället, men genom det industriella skogsbrukets utveckling började man alltmer betrakta lövträden som ett problem. Lövträden gav sämre lönsamhet på grund av att de inte efterfrågades inom industrin och lövträden ansågs även hota barrträden och deras föryngring genom sin förmåga att föröka sig vegetativt genom stubbskott och rotskott. Det fick till följd att det inom skogsbruket talades om ett ?lövproblem?.

The role of mast cells and mast cell mediators in the development of atopic dermatitis in a mouse model

Atopic dermatitis (AD) is a complex, often lifelong allergic disease affecting around 10 % of both dogs and humans. The hallmark symptom is severe pruritus, causing a lowered quality of life. Mast cells (MCs) are known to play an important part of the immunopathogenesis, promoting a faulty T helper cell type 2 (Th-2) response which follows by a production of specific immunoglobulin E (IgE) antibodies towards environmental allergens (Ag). To further investigate the role of MCs and its mediators in the progression of AD, a low-calcemic vitamin D3 analog (MC903) was used to induce AD-like symptoms locally on the ears of two different knock-out (KO) mouse strains. The first strain was Wsh-/- mice deficient in MCs.

Hållfasthetsanalys av infästningmellan AGV och motor : med hänsyn till femfaldig säkerhet mot brott

Automated Guided Vehicles, AGV:er, används i huvudsak som monteringsplattform inom tung fordonsindustri. En AGV kan användas vid montering av motorer, växellådor och chas-sin. AGV:n transporterar produkten genom en slinga i fabriken, där produkten monteras. Idag säljs AGV:n med ett löfte om femfaldig säkerhet mot brott för alla de ingående komponenter-na. AGV:n är konstruerad för att bära upp en last på maximalt 1800 kg, med säkerhetsfaktorn inkluderad.

Snabbt, säkert eller skönt? : Cyklisters preferenser i trafiken

Since the late 50th century, the automobile has been normative in the Swedish society (Lundin 2008). This has led to an urban environment deeply characterized by the motor vehicle and its necessities, while other means of transportation, such as train and bicycle, have been ignored and put aside. However, over the past decades, a new trend has been seen in urban planning as a consequence of the increasing knowledge of the negative qualities caused by the car. As a result, the bicycle is seen as a conceivable transport mode.This thesis examines cycling on four issues:- Why is there a need of more cyclists? - How can the total number of cyclists as well as the number of satisfied cyclists increase? - Which factors affect the choice of transport mode? - Which factors affect the choice of route?The first two questions are discussed from a literature study that was conducted at the beginning of the thesis.

Re-design av BEV-heater

Denna rapport beskriver det examensarbete som utförts på Calix AB under vårterminen 2013. Calix AB tillverkar värmare för bland annat batteri och kupé till fordonsindustrin. Uppdraget i detta examensarbete var att göra en omkonstruktion på BEV-heatern (Battery Electrical Vehicle) som är en batteri- och kupévärmare till el och hybridfordon. Problemet med den nuvarande konstruktionen är att den bygger på delar från äldre värmare till fordon med förbränningsmotorer, samt att konstruktionen inte är lämplig för produktion i större serier. Krav som Calix AB hade var:Integrerat ChassiMinimera tryckfallUnderlätta montering och tillverkningUppfylla standarder satta av fordonsindustrinKunna monteras ?in-line? i fordonetFör att kunna genomföra projektet var vi till en början tvungna att få kunskap om hur den befintliga BEV-heatern fungerar.

Entreprenören i servicebranschen

Sammanfattning (for english: scroll down) Titel: Entreprenören i servicebranschen Seminariedatum: 2007-05-31, 2007-06-01 Kurs: SMT302 Kandidatuppsats 10p Författare: Jimmy Heijel, Lars Jacobsson, Fredrik Svensson Handledare: Elin Bommenel, Carl R. Hellberg Nyckelord: Entreprenören, serviceentreprenören, servicebranschen, service management, kontrollens lokalisering, innovationsförmåga, riskhantering, prestationsbehov och intuition. Syfte: Att med utgångspunkt i entreprenörers vedertagna egenskaper identifiera beskriva och analysera egenskaper som särskiljer entreprenörer i serviceverksamheter. Metod: Arbetet genom uppsatsen har följt ett kvalitativt angreppssätt där en deduktiv ansats använts. Två intervjuer har gjorts med entreprenörer verksamma i näringslivet.

Kartläggning och analys av livslängdsstyrande faktorer för dragbrotschverktyg

Detta examensarbete utfördes vid Uppsala universitet i samarbete med Scania CV AB. Scania Commercial Vehicle Aktiebolag, Scania CV AB, är en tillverkare av tunga lastbilar, bussar samt industri- och marinmotorer. På Scania transmission i Södertälje finns ett av företagets största och dyraste verktyg. I dragbrotschningsprocesser används dragbrotschverktyg som per styck kostar allt från 50 000kr och upp till strax över 1 miljon kronor beroende på storlek och utformning.Uppdragets syfte är att kartlägga faktorer som styr ett dragbrotschverktygs livslängd och undersöka alternativ som bidrar till att sänka dragbrotschningsprocessens kostnad per producerad artikel. Mål är att göra en beskrivning av nuvarande system och processer samt kartlägga vilka faktorer som styr dragbrotschverktygens livslängd.

Ruttdetektering av tågtrafik

This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.

Teknik för biogasanvändning

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.
