Pappersmakulatur uppstår i tryckpressarna, men orsakerna finns i företagets alla funktioner. För ett framgångsrikt förbättringsarbete med att minska makulaturen krävs därför att all personal är engagerad.Examensarbetet utfördes på Bobergs Tryckeri AB i Falun, ett familjeägt företag med 60 anställda, som producerar personifierad direktreklam och blanketter. Syftet var att undersöka hur pappersmakulaturen kan minska och målet var att hitta orsaker samt ge förslag på åtgärder för att minska den.Genom intervjuer med personalen kartlades produktionssprocessen och utifrån det utarbetades förbättringsförslag. Exempel på förbättringsförslag är att kontinuerligt mäta och rapportera makulaturen, förbättra kommunikationen mellan avdelningarna och utveckla färgstyrningen. Litteraturstudier och kontakter med nyckelpersoner inom branschorganisationer och andra liknande företag, var till stor hjälp i arbetet.

Man has through out times and in all cultures shaped their bodies to the existing bodily ideals. Men's bodily ideals had changed over the last thirty years to a more muscular, less bodyfat and more V-shaped body. Men and women focus their attention to different body parts. That is why there is a need for a questionnaire witch is specially designed for men. The purpose of this study was to deliniate the body image of men aged 20 to 30 years and to test the reliability of the questionnaire "Mäns kroppsuppfattning".

Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.

Government regulations and customs duties restrict the import of trucks to some of the markets to which Scania tries to sell their trucks. The distribution problem due to these regulations is solved by the foreign assembly department, KD, at Scania. This means that competence is needed and costs are added not related to Scania's core operations.The aim of this master thesis has been to analyse and to evaluate alternative ways of managing the packing operations considering cost, quality and work organisation. To study and examine the work methods and operations of today and also to present methods measuring the operations effectiveness and productivity.We have used the system approach to maintain totality and to understand the component's relation to this totality. Field studies combined with studies of relevant literature and studies of other companies operations have given us the knowledge and the understanding of the packing operations needed.

Health and fitness are two controversial and not easily defined topics that affect people in our modern society every day. We believe that we can find a link between individualism, globalization and the stress concerning weight and appearance ideals. Our bodies have turned into a popular subject for the media, and there is no indication that the interest will decline. As the world gets more artificial, "natural" ideals are getting more attention, such as the concept of a strong and healthy body. But there is also a downside, for example with health issues such as cardiovascular disease increasing following the birth of high-fat diets.

Glutathione (GSH) is a molecule that consists of three amino acids: glutamic acid, cysteine and glycine. GSH has several important functions: to protect cells from free radicals, reactive oxygen species and oxidative stress. GSH exists in a reduced form, GSH, and in an oxidized dimeric form, glutationdisulfid, GSSG. The enzymes glutathionereductase (GR) catalyses the reduction of GSSG back to GSH. Nicotinamide adenine dinucleotide phosphate (NADPH) is required as a coenzyme in the reaction.

This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

Objective: The aim of this study was to compare equations used to calculate BMR to values of BMR obtained from measurements in order to determine the most suitable equation to be used on children and adolescents with CF.Design: The participants where children and adolescents with CF. Data was collected from the division of Clinical Nutrition at Uppsala Akademiska Sjukhus. Age, weight, height, BMI, BMR, FFM and FM was recorded from 27 measurements. BMR from the participants collected from the indirect respiratory calorimetry was compared to the results obtained from five equations used to obtain a calculated value of BMR.Results: Tverskayas equation was best correlated with the measured BMR for the whole group. The equation underestimated BMR for the participants with a measured BMR over 1400 kcal/24h and overestimated BMR for participants with a measured BMR under 1400 kcal/24h.

Lättviktsskivor till möbelindustrin har varit ett omskrivet tema i olika branschtidningar den sista tiden.Detta examensarbete beskriver och undersöker en ny konstruktion av en lättviktsskiva i massivt trä.Lättviktsskivan är uppbyggd som en sandwichkonstruktion i tre skikt. Ytskikten består av 6 mm tjockalimfogar och kärnmaterialet av profilerade distanser. Materialet är furu och lättviktsskivan har endensitet på 320 kg/m3 vid 39 mm tjocklek. Utifrån kontakter med utvalda tillverkare och användare avskivmaterial, samt genom tester, har denna konstruktion granskas och förslag på förbättringar har tagitsfram. Den ursprungliga distansen som var sammansatt av två halvor med centrumhål har ersatts av enmassiv distans med en liknande profilering.

Fetma och övervikt är ett allt mer vanligt problem över hela världen och därav ökar även överviktskirurgin. Gastric bypass är den vanligaste metoden i Sverige och ses som ett redskap för viktminskning. För att bibehålla viktminskningen spelar andra faktorer än operationen en roll hos patienterna. Studiens syfte var att finna framgångsfaktorer vid en bibehållen viktminskning postoperativt. Metoden var av fenomenologisk narrativ karaktär och datainsamlingen skedde med hjälp av intervjuer.

The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.
