Påverkan av skogsbrand på litiska arkeologiska fynd ? experimentell simulering av brand
This is a paper about the effects from smoldering fire on lithic objects from an archaeological view.
The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.
Skapande av innovativ och välunderbyggd konceptdesign med stöd av ramverk för medierad handling : En undersökning av hur ?The Mediated Action Sheets?, ett ramverk för interaktions- och tjänstedesign, kan och bör användas
Under den diffusa delen av ett projekt i interaktionsdeign fattas beslut om vad som ska skapas. För att strukturera denna process rekommenderar Arvola (2013) ett ramverk för beskrivning av medierad handling. Utöver ett antal informella intervjuer med personer som använt ramverket har inga undersökningar genomförts vars resultat beskriver hur ramverket används i praktiken. Studier som visar hur ramverket bör användas för att ett användbart resultat ska genereras har inte heller gjorts, förrän nu. Genom att under två workshops studera interaktionsdesigners generera designkoncept med stöd av ramverket för medierad handling, har fyra kännetecknande aspekter av hur ett bra designkoncept kan skapas med stöd av ramverket identifierats.
Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun
Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants.
When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

Manuell kontanthantering i begränsad omfattning : Strategi och styrning på funktionsnivå inom bankbranschen
In today?s ever-evolving society the use of cash is replaced by digital services in the banking sector. Some local banks restrict manual cash handling while others remove it completely. This essay examines how management accounting is affected by restricted cash handling. The theory clarifies that management accounting strategies create guidelines and provides specific framework for employees and managers in the organization.
Effektivare hantering av foderspannmål : en fallstudie
The purpose with this work was to investigate some alternatives for an effective handling with grain, to find the most economic alternative.
It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this paper. I have used the systems as a basis when I made calculations in handling the grain for a company.
I have chosen a company placed in south of Sweden. The productions are crop farming and pork.
Konservera eller kassera - förvaring och vård av biblioteksmaterial på 40 svenska folkbibliotek
This thesis is based on an investigation to find out in what way 40 Swedish public librarieskeep and preserve their library materials. The investigation is based on inquiries sent outto the libraries. It deals with the keeping of books with regard to external factors which havedestructive effects on library materials as well as the safety at the library buildings. It is, aswell, about the preserving work being done at the libraries.Comparisons are made with literature and accounts about preserving measures and recommendationsregarding appropriate environment in premises and depositories. The resultsshow great differences between the libraries as to the library environment, i.e.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
Möjlig kvittblivning och eftermarknad av ridbaneunderlag - topplager
The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

The reproductive behaviour of the cat is explained and the development of kittens is described. The study highlights hunting behaviour, territory structures and social life of cats. The report also includes practical instructions to how the environment and handling of cats in clinics can be improved..
Kalkyl för logistikkostnader; från leverantör till förbrukningsplats
The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.
LIDESK : En materialstudie för Edsbyverken
Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.
Sex i skolbiblioteket : Kunskap, makt och konstruktionen av sexualitet på svenska skolbibliotek
The purpose of this essay is to investigate the construction of sexuality in Swedish school libraries through the lens of Foucault?s concept of power/knowledge. Five libraries were investigated, using two kinds of method: discourse analysis of titles, classification codes and subject headings of sex education materials, and qualitative interviews with librarians working at each of the libraries. Most sex education materials were classified within the medicine section, illustrating the continued authority of medical discourse in matters concerning sexuality. Books for younger audiences were often written for either boys or girls, reproducing a binary understanding of gender.

Today?s housing system for laying hens has limitations for the hens natural behavior. Despite the current law of prevention of cruelty to animals, this might implicate health problems for the hens. This degree project is aiming to improve the situation for laying hens in cage-systems. The aim with our project is to bring forward a draft of a cage that improves the welfare of laying hens.
Returhantering vid LensLogistics AB: en process- och
flödesutredning för förbättringar
Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.
