Undersökning av sågverks effektivitet med avseende på underhåll : Vikten av en kostnadseffektiv underhållspolicy

Det finns stora förluster i sågverk som inte framkommer av deras traditionella driftsuppföljnings¬processer. Strategiskt viktigt för organisationen är frågan vad företaget behöver göra för att bli effektivt. I detta arbete diskuteras mätmetoder av effektivitet med avseende på underhåll och hur effektiviteten kan mätas med hjälp av att beräkna den totala utrustningseffektiviteten (OEE). Arbetet beskriver också olika underhållsstrategier och processen med att införa en sådan policy på sågverk. Under en period av sex dagar beräknas OEE på fem sågverk.

Obtaining high quality textile fibre from industrial hemp through organic cultivation

AbstractThe urgency to find alternative fabrics to conventionally produced cotton is increasing as vast amounts of agrochemicals are used and a lot of irrigation is required. In this literature survey the potential of organic cultivation practices to produce highly qualitative hemp fibre, suitable for the textile industry, was investigated. The definition of a fibre in the textile context as well as of the qualities that are essential for a textile fibre was necessary as a base for the discussion in this thesis. The quality parameters looked at were fineness, strength, length, friction, and colour. The impact of external growth factors and plant development on these quality properties are discussed.

Hur kan måltiders klimatpåverkan minska? : Hinder och mo?jligheter fo?r va?xtbaserad kost vid offentliga matserveringar.

Människans utsläpp av miljö och klimatpåverkande växthusgaser har ökat i snabb takt de senaste hundra åren. Fler varor produceras, konsumeras och transporteras över hela jorden för att uppfylla de krav människor har på sin levnadsstandard. Livsmedelsindustrins roll i utsläppen är betydande, speciellt köttproduktionen, som står för 18 procent av världens totala växthusgasutsläpp. Genom att minska den mängd kött som ingår i människors måltider och gå mot att äta mer växtbaserat, som inte innehåller köttprodukter, kan matens miljöpåverkan minska. Ett viktigt område är offentliga matserveringar, vad som serveras där har en inverkan på människors matvanor och deras syn på mat.

Avbördningskapacitet för Traryd kraftverk: en modellstudie vid dimensionerande flöde

Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.

Gas som bedövningsmetod vid slakt av slaktkyckling :

Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Folkbiblioteks och släktforskarföreningars stöd i släktforskares egen forskning sett ur ett självstudieperspektiv

The purpose of this thesis is, from a self directed learning perspective, to investigate the support of public libraries and genealogy associations of genealogists' own research, i.e. their search for ancestors as well as their possibilities to broaden their history outlook. Accordingly, five public librarians and five genealogy representatives in the west of Sweden have been interviewed regarding the support that can be offered to genealogists. The investigated support to genealogists in their own research is about working environment, literature and material, activities and the cooperation between public libraries and genealogy associations. In this thesis conclusions are merely drawn from a self-directed learning perspective, a perspective where also different forms of support are being recommended by scientists.

Optimalt råvarulager för biobränsleföretaget :

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.
