Outnyttjad kreativitet och kompetens inom produktion : - Ett arbete som fokuserar på att fånga upp och ta tillvara på medarbetares kreativitet och kompetens
AbstractResource efficient manufacturing is a term that has been increasingly applied within manufacturing, where one of the key points is to reduce waste of such forms that do not add value for the end customer. By the Lean principles, there are seven plus one types of waste, in which the definition of the eighth point varies among sources. In this study, the eighth type of waste has been interpreted as the untapped creativity and competence among employees that has not been put to use. From this, our question was incubated; How can you make the most of the employees? untapped creativity and potential within manufacturing? The case study will be developed with empirical data obtained from Dometic Group by conducting interviews.From the gathered literature, it was concluded that the communication between employees contributed to an increased understanding of one another as well as it allowed for improvement in work.
Upplösningen, Före-Under-Efter : En intervjustudie av åtta människors upplevelse av en separation
Syftet med denna uppsats var att belysa och bidra till förståelsen av individens upplevelse av separationsprocessen. Vi ville även undersöka om det fanns några könsskillnader när det gäller denna upplevelse. Vi har genomfört en intervjuundersökning med fyra kvinnor och fyra män. De teoretiska utgångspunkterna var Giddens teori om intimitet och modernitet, Beck och Beck- Gernsheims teori om individualisering samt Antonovskys teori KASAM. Intervjuerna har tolkats enligt hermeneutiska principer.
Outnyttjade resurser inom park- och naturvård
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Barns upplevelser när föräldrarna genomgått skilsmässa : En litteraturstudie
Skilsmässor är vanligt förekommande och barns upplevelser av föräldrarnas separation handlar ofta om att de känner sig stressade och förvirrade. Tidigare studier visar, att skilsmässan medförde stora förändringar för barnen. Påfrestningar i familjesituationen efter skilsmässan påverkade barnens känslor, vilket ofta yttrade sig i en sorg efter förlusten av att inte vara en hel familj längre. Syftet med studien var att belysa barnens upplevelser när föräldrarna genomgått skilsmässa. Metoden som användes var en litteraturstudie med kvalitativ ansats.
Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning
The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.
Den kontrollerade tekniken : En studie om de exklusiva Plymouthbrödernas förhållande till samtida teknik
The purpose of this thesis is to examine the Swedish Plymouth brethren?s relation to contemporary technology. What types of technology are considered acceptable and where do they draw the line? Due to the brethren?s separation from the parts of the world they believe leads people away from God, such as the entertainment industry, immoralities etc., they reject use of television and radio. These two are viewed as uncontrolled types of technology since the user does not have control of its contents.
Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.
Hylshantering samt flödesanalys
Trioplanex International AB is a part of the group Trioplast Industrier AB, which produces packaging materials for the film and hygiene industry. The group is active throughout Europe, where most of the production is located in Sweden, with head office in Smålandsstenar. Operations in Landskrona consist of Trioplanex International AB and Trioplast Landskrona.Semi-finished articles consisting of paper cores, so called bobbins, give rise to a high amount of core waste in any form of core cutting. The objective of the report is to map out all core waste and illustrate the material flow with regard to present layout and equipment.In the beginning of the project an analysis of the current process was carried out with focus on the cutting equipment. A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.
Ekonomiska styrmedel för förpackningsavfall : En studie om vad som påverkar återvinningen i EU
In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.
Mammans betydelse : effekter av tidig maternell separation hos däggdjur
Däggdjur diar sina ungar under den första tiden efter förlossningen men hos många arter består moderskapet av mer än att bara erbjuda mat. Många däggdjur som hålls i fångenskap har separerats från sina mödrar långt tidigare än vad som sker i naturen och separationen sker ofta abrupt utan möjlighet för ungarna att successivt vänja sig vid de nya förutsättningarna som separationen innebär. Syftet med den här litteraturstudien är att undersöka vad som är viktigt i moder-unge-relationen, för att sedan titta på hur däggdjurs beteende påverkas av att förlora sin mamma tidigt i livet, och hur problemen kan undvikas med exempel från häst, får, nötkreatur, gris, gnagare, mink och primat. Det sociala bandet som bildas mellan moder och unge strax efter födseln är viktigt för att de ska känna igen varandra och hos vissa arter är det livsviktigt för ungarnas näringsintag och överlevnad. Hos de flesta arter verkar dock moderns närvaro och omvårdnad vara minst lika viktig, om inte viktigare för ungarnas utveckling och välbefinnande.

Utveckling av en LC-MS-metod för analys av gamma-hydroxibutyrat, gamma-butyrolakton, 1,4-butandiol, amfetamin och metadon
In this project a LC-MS-method for the analysis of gamma-hydroxybutyrate, gamma-butyrolactone, 1,4-butanediol, amphetamine and methadone was developed.Initially, the efficiency of the ionisation of the analytes was evaluated with respect to the ionisation technique (ESI, APCI and APPI) and the composition of the mobile phase. In the next step a number of different columns was tested in order to find the one with the greatest potential for separation of the substances in question. Using the selected column, the separation was optimised by means of experimental design and the software The Unscrambler 7.8. The parameters studied were the flow rate, the column temperature and the mobile phase composition. The response variables were the resolution between the target compounds and the retention time of the last eluting compound.These experiments showed that, in order to obtain the best ionisation, the mobile phase should consist of 5 mM formic acid in water and acetonitrile.
Varats olidliga tomhet : En psykoanalytisk texttolkning av Herman Hesses Siddhartha
Föreliggande studie utgör en psykoanalytisk texttolkning av den tysk-schweiziske författaren Hermann Hesses Siddhartha ur ett objektrelationsteoretiskt perspektiv. De metoder som tillämpas är den traditionella hermeneutiska texttolkningsmetoden och den kliniska psykoanalytiska överförings- och motöverföringsmodellen. Medels dessa tolkningsmodeller och objektrelationsteorier, särskilt Melanie Kleins, Donald W. Winnicotts och James Mastersons, åskådliggörs den svårfångade emotionella problematik som alla individer med preoidipala svårigheter eller brister i självet ger uttryck för.Utgångspunkten för texttolkningen är teorin om den infantila omnipotenta fantasin, fantasin om att kunna uppnå ett tillstånd av absolut balans, behovs- och begärslöshet, vilken texten är genomsyrad av. Denna fantasi framstår i ljuset av textens primära utvecklingskonflikt kring separation-individuation och dess narcissistiska grundstruktur som ett uttryck för sökandet efter det sanna självets natur och dess förlösande, ett sökande, vilket fram till insiktsögonblicket effektivt omintetgörs av det falska självets verklighetsförvanskande och verklighetsförnekande försvar..
Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare
Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil.
Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.
Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm
Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years. Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed. Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.
