Slöserijakt i betongdjungeln : En tidseffektivisering av monteringsprocessen inom stål- och betongprefab

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Design och konstruktion av Splitmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Neurointensivvårdspatientens förutsättningar för ett optimalt neurologiskt wake-up test : en observationsstudie

Background: Examinations with the intent to assess neurological functions and level of conciousness are common in neurocritical care, but the effect on the patient is not entirely researched.Aim: The purpose of this study was to describe the patient?s situation at the neurological wake-up test concerning the environment, nursing interventions and the possibility given the patient to become awake, and if these conditions affect the outcome of the wake-up test.Methods: A quantitative observational study took place at a neurocritical care unit, where 20 patients were observed from interruption of sedation to the neurological assessment, which was performed by a neurosurgeon or a specialized critical care registered nurse. Nursing interventions, environmental factors and physiological parameters were documented.Result: Twelve intervention varieties to control patients? physiological parameters were used. CPP > 80 mmHg was found in 90 % of observations.

Utredning av energieffektiviseringspotential i ett flerbostadshus : Avseende på injustering av värmedistributionssystemet och installation av värmepump

F?r all sten i Sm?land: Inventeringsunderlag f?r kulturhistorisk v?rdering av stenmurar

This thesis focuses on the construction of drystone walls in the county of Sm?land, as well as their historical value and significance to the county. In Riksantikvarie?mbetets Plattform Kulturhistorisk v?rdering och urval, a directory for historical evaluations of buildings and objects, the first clause is to describe the object and its history. When trying to do this, the lack of literature focusing on the constructional elements of drystone walls and their history became an issue and is what prompted the writing of this thesis. With a study of different handbooks, a compilation of the constructional elements of the walls were put together.

Kommunalstrejken 2003 : Motståndet mot en uppvärdering av kvinnodominerade sektorn

Urination is a biological need but the routines surrounding urination are culturally specific and ever changing. This makes the organization of public space an important part in deciding what actions are made possible for the people in it. This paper considers women?s public urination and the possibilities to merge the need to urinate and the construction of the female body as feminine.A number of texts that describe the construction of the female body and identity as both gendered and socially produced are analysed in relation to women?s experiences of incontinence. Incontinence as a medical diagnosis is by this becoming possible to question, and may be seen as one of several strategies used to manage both the organization of the public space and the expectations of the female body to be a docile body.The conclusion is that a woman who wants to enter public space has the following options when it comes to the need to urinate:To strive for the feminine ideal.

Analys av lageregenskaper utifrån mätningar i testrigg

Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

That is why this examination paper has as purpose to answer the question if it is possible to make slab blocks built in the sixties more energy efficient. This is done by calculate energy efficient measures on a chosen apartment block at Maratonvägen in Halmstad, in an energy and expense perspective.MethodThe examination paper is based on different methods, mainly calculation but also qualitative conversation studies, economic calculations and literature studies.

Effektivisering av ventilationsprojekt : Bravida Filial Uppsala

In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.

Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Ett hållbart val för premiepensionen - En studie av miljö/etiskt märkta fonder i premiepensionssystemet

I uppsatsen undersöks hur 11 globala miljö och/eller etiskt märkta fonder har presterat i jämfö-relse med 17 konventionella fonder i det svenska premiepensionsutbudet genom tillämpning av utvalda finansiella prestationsmått. Detta med anledning av att miljö och/eller etiskt märkta fonder har haft en stor framväxt under det senaste decenniet och det finns därför en efterfrå-gan av att klargöra ifall en pensionssparare behöver göra avkall på den finansiella avkastningen vid val av miljö och/eller etiskt märkta fonder. En jämförelse av det statliga förvalsalternativet och 10 globala miljö och/eller etiskt märkta fonder har även gjorts för att undersöka skillnaden av att vara en aktiv respektive passiv premiepensionssparare då antalet som inte gör ett aktivt val är omkring 50 procent. Resultatet visar ingen statistisk signifikant skillnad med avseende på den riskjusterade avkastningen mellan fonder som är miljö och/eller etiskt märkta och fonder som inte tar hänsyn till dessa kriterier vilket överensstämmer med tidigare forskning. I jämfö-relsen mellan det statliga förvalsalternativet och 10 globala miljö och/eller etiskt märkta fonder har det förstnämnda presterat på en hög nivå..

Fodrets inverkan på resultatet vid undersökning av förekomst av ockult blod i avföringen hos hund :

Hemoplus® (Sarstedt, Nümbrecht, Tyskland) is a guaiac-based fecal occult blood test developed for human medicine. Guaiac-based tests make use of the pseudoperoxidase activity of hemoglobin so the test is not specific for human hemoglobin and can therefore be used in veterinary medicine. Peroxidase-containing foods such as meat (hemoglobin and myoglobin) can cause false-positive results of the test. To ensure that a positive result is not caused by diet, it has been suggested that canine patients should be fed a meatless diet for a few days prior to fecal occult blood testing. The aim of this study was to evaluate the effect of commercial dog food on guaiac-based tests. In this study fecal samples from healthy dogs were analyzed with Hemoplus®.

Humorstilar, Emotionell Perception och Kön ? Vem skrattar mest och vem skrattar sist?

The main aim of this research was to investigate four humour styles, affiliative, self-enhancing, aggressive, and self-defeating humour, and compare these with emotional perception. Forty-eight persons took part in the research, 27 women and 21 men living in the southern part of Sweden. Two humour tests were used: the Humour Scale Questionnaire ? HSQ, with 32 items, and a newly composed video test, assembled after pilot testing from 26 video clips, the Humour Video Questionnaire ? HVQ. To measure perception and interpretation of emotion, the revised version of the ?Reading the Mind in the Eyes? Test was used.
