Förslag till förbättringar av materialhanteringen kring packningslinan hos Spaljisten AB

The purpose with this report is to give structure to the storage area betweenproduction and packaging at Spaljisten AB in Åseda. The purpose is also to givesuggestions for improvements of work tasks and thereby simplify and improve thematerial handling at the packing process.The background of the task is that Spaljisten AB is going to increase theirproduction and thereby they also need to increase the packing rate of theirproducts. They will manage this by installing a new automated packing line andincrease the efficiency of the old manual one. The theoretical background ismostly obtained from literature which contains relevant facts for our report.The storage area has been studied visually in order to search for improvements oftoday?s layout.

Kappa Control with Online Analyzer Using Samples from the Digester's Mid-phase

In the pulp industry, digesters are used to disolve lignin in wood chips. The concentration of lignin is measured and is called the Kappa number. In this thesis, the question of whether an online Kappa sensor, taking samples from the mid-phase of the digester, is useful or not is analyzed. For the samples to be useful, there has to be a relationship between the measured Kappa at the mid- phase and the measured Kappa in the blowpipe at the bottom of the digester. An ARX model of the lower part of the digester has been estimated.

Det maskerande brusljudets påverkan på inlärningen av visuell information : om effekten av maskerande brusljud i öppna kontorslandskap

Denna experimentella studie undersökte om maskerande brusljud på ovidkommande tal påverkar inlärning av visuell information. Experimentet genomfördes i ett laboratorium med 32 försöksdeltagare. Visuella ord presenterades för försöksdeltagarna samtidigt som auditivt tal från samma semantiska kategori, med eller utan maskerande brusljud, presenterades. De visuella orden skulle återges i valfri ordning. Resultatet av studien visar att ett maskerande brusljud på ovidkommande tal har positiv effekt på inlärningsförmågan.

Beröringens makt : En litteraturöversikt om hur vårdpersonal använder sig av beröring i omvårdnaden

Background: Human interaction by touch plays a central role for our health and well being throughout life. When people touch each other our bodies release a hormone called oxytocin into the bloodstream, this gives the body a soothing effect. Touching on the other hand can be perceived as unpleasant if it is not in accordance with the patient?s norm or wishes. From biblical times and through to today human touch plays a central part of nursing.

Skolbibliotekets verksamheter ? en studie av hur skolbibliotekarier och lärarbibliotekarier prioriterar skolbibliotekets verksamheter utifrån social identitet

Different educational and professional backgrounds play important roles in how school librarians prioritize activities in the school library. Whether the school librarian has a background as a teacher or as a librarian, they influence and apprehend the activities of the school library differently. The aim of this thesis is to find out how the school librarian looks at his/her commission. What shifts in priorities can be recognized depending on whether the librarian has training as a teacher or a librarian. This thesis also analyzes how the two different professional backgrounds justify their priorities in the school library.

Testbänk för motorbåtsdrev

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Diagnos av stiktion i reglerventiler för prediktivt underhåll

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

Hemlösa personers upplevelse av mötet med hälso- och sjukvårdspersonal : en litteraturöversikt

Background: Homelessness is increasing, and health care is still difficult for many homeless people to achieve. If they get sick, it is both technically challenging to get a clinic they can go to, but also an economic problem because most of the homeless have no gainful employment. The fact that many homeless people experience bad attitudes of health care professionals is one reason why they don?t seek healthcare until an emergency arises. In the profession as a nurse, all people should be given equal treatment regardless of background.

Utvärdering av ett värmepumpsystems prestanda till en HWC-tvättmaskin : Med fokus på fläktvarvtal och köldmedieflöde

This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.

Bilden som kommunikationsverktyg

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

Vi har i alla fall aldrig varit apor! : En postkolonial studie om kreationism bland unga

This case study examines how a group of upper secondary school students in a multiethnical suburb of Stockholm reason about the theory of evolution. The theoretical background of the thesis is postcolonial and the questions raised were how spread the creationist thoughts are in the group; in what way the backgrounds of the students are relevant to their thoughts; how the students construct the notion of the theory of evolution; how they position themselves and others in relation to the discourse of the theory of evolution; if there are any differences between students at the collage program of natural science and the collage program of social science, and in that case, what differences; and who or what inspires the young in their thoughts about the theory of evolution. To answer these questions both a survey poll and interviews were used. The result of the case study showed that a majority of the students at the investigated school has creationist ideas and that the students profiled on social science have creationist ideas in a wider extent. Another result is that the religious background seems to be relevant to develop creationist thoughts, while the variables gender, home district and educational level did not differ the creationist group from the whole group.
