Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

Modifiering av ett generiskt postoperativt instrument till ett instrument speciellt inriktat mot kranskärlsoperation

Syfte och mål: Syftet var att modifiera och utvidga det generiska instrumentet ?Postoperative Recovery Profile? (PRP) för att utvärdera återhämtningen efter kranskärlsoperationer (Coronary Artery Bypass Grafting (CABG)). Bakgrund: Efter en kranskärlsoperation riskerar patienterna att drabbas av en mängd olika postoperativa symtom. Goda kunskaper om återhämtningsprocessen är en förutsättning för god omvårdnad. Vi kunde inte finna något procedurspecifikt instrument för utvärdering av de postoperativa symtomens omfattning och varaktighet efter denna typ av operation. Design: För att utveckla ett procedur-specifikt instrument i form av ett frågeformulär användes en kvantitativ design. Metod: Det generiska instrumentet PRP innehållande 19 punkter, modifierades och utökades med procedur-specifika symptom som identifierades genom en litteraturöversikt. Innehållsvalideringen genomfördes med sjukvårdspersonal (n = 15), inneliggande patienter (n = 12) och polikliniska patienter (n = 4).

Upplevd arbetsmiljö : En kvalitativ studie om omsorgsgivares erfarenheter av ledningens och organisationens inverkan på deras arbetsmiljö

The aim of this essay was to describe and interpret the managements and organizations impact regarding the caregivers working conditions. To examine this we used a qualitative method. We completed two group interviews and five individual interviews with a total of fifteen enrolled nurses that worked within elderly care. In our interviews we found that the enrolled nurses felt that the organizations economic interests collided with their personal values regarding good quality elderly care. We also found that the caregivers experienced that they had an impact on their working conditions and that their employer was the main reason for making it possible..

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 one hour?s 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.

Kvantifiering av föroreningstillskott från dagvatten inom skyddsområdet för Göta Älv : en simuleringsstudie med modellen SEWSYS

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

Sidofördelning av främre korsbandsskador i olika idrotter : en registerstudie baserad på data från svenska korsbandsregistret 2005-2014

AimThe aim of the present investigation was to study the side distribution (right, left) and possible gender differences in terms of anterior cruciate ligament (ACL) injuries in different sports.MethodThis Register study comprises a total of 27856 subjects from the Swedish National Anterior Cruciate Ligament Register. Side- distribution and possible gender differences were analyzed. The different sports consisted of aerobics, alpine skiing, basket, cross-country skiing, dancing, enduro, floorball, gymnastics, handball, ice hockey/bandy, martial arts, outdoor activities, racket sports, snowboard, soccer, and volleyball. Due to injuries that had occurred in the traffic and at work 5076 subjects were excluded. Statistical data have been analyzed with one way ANOVA and x2 test and the Tukey post hoc test has also been used.

Död ved i gallrad skog och nyckelbiotoper : en jämförelse av habitatkvaliteter för vedlevande lavar och mossor

A high amount of dead wood is one of the most important prerequisites for high biodiversity on forest land in Sweden. Dead wood is most abundant in young forests, thinned forests, woodland key habitats and protected forest land. In old-growth forests most of the dead wood consists of logs and snags, whilst in managed forests a huge proportion of dead wood is made up of logging residues like stumps and FWD, fine woody debris (< 10 cm diameter). All these different types of dead wood may serve as substrates for epixylic bryophytes and lichens. However, few studies have been conducted on the relative importance of these different fractions of dead wood for the occurrence of bryophytes and lichens, especially when considering dead wood on thinned forest land.

Fodersammansättningens betydelse för tillväxt hos häst :

The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.

Vandring av vårlekande fisk och jämförelse av fångst mellan ryssja och strömöversiktsnät i Hammerstaån, Stockholms län

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net calledströmöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

Hydrauliken i Ångersjöns fosforfällor : bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter

Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. Blast furnace slag is a by-product from iron production, and has in laboratory trials showed good phosphorus binding capacity. To test blast furnace slag as a reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The plant contains two parallel lines, one with blast furnaces slag and the other with Filtralite-P as phosphorus sorbent. Both filters have showed decreasing phosphorus purification effect with time in spite of a low wastewater load.

Jämförelse av två olika fälttest för fotbollsspelare på olika tävlingsnivåer

SammanfattningOlika fälttest är flitigt använda för att utvärdera fotbollsspelares fysiska uthållighet, däribland Yo-Yo Intermittent Recovery Level 1 (Yo-Yo IR1) och Coopers löptest. Ytterst lite är dock känt om Coopertestets lämplighet som mätmetod i en sport med intermittent arbete som fotboll. Syftet med denna studie var att undersöka prestation i Coopertestet i förhållande till Yo-Yo IR1 testet hos fotbollsspelare på olika tävlingsnivåer. Under försäsongen testades 19 manliga fotbollsspelare (23 ± 4 år, 181 ± 9 cm, 77 ± 9 kg) från svensk division 1 (hög-nivå, n=5), division 3 (mellan-nivå, n=6) och division 5 (låg-nivå, n=8). Coopertestet består av oavbruten löpning så långt som möjligt under 12 minuter på löparbana.

Framtagning av nyckeltal som indikerar kvalitetsbristkostnader : Development of key performance indicators revealing the cost of poor quality

Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.
