The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

An attempt was made to GFP-tag the effector proteins of AvrLm6 and AvrLm4-7 using the GFP-tagging gene knockout method (GGKO) developed by Saitoh et al. (2008) in order to determine whether or not they are secreted. Successful pETHG-(target)KO vectors were not generated. The protocol was examined for potential errors. Fatal errors were pinpointed to the ligation reaction and the transformation required to generate and propagate the desired vector pETGH-(target)KO.

The aim of this review is to evaluate the best way to transport the horse. When it comes to transporting horses there are a number of different types of trailers and trucks that you can choose from today. The most common type of trailer is designed for two horses and the horses are transported facing the direction of travel. Studies has been performed to determine if that is the most advantageous direction for the horse to travel in, in terms of balance and levels of stress. Stress is a widely discussed subject and the definition is not fully developed.

Denna rapport beskriver framtagandet av Katastrofsjukhus, robustare fältsjukhus med förbättrad standard. Jämförelse görs mellan det framtagna Katastrofsjukhuset och uppblåsbara tältsjukhus samt standarden i svenska sjukhus. En färdig produkt finns ännu inte framtagen och rapporten lämnar en hel del lösa trådar, men är en bra grund för mer omfattande utveckling av konceptet och som en idéstudie till en vetenskaplig avhandling eller annan fortsatt forskning.Problemet med befintliga fältsjukhus är främst miljön i operationsavdelningen. Detta är något det lagts stor vikt vid och en strävan att uppnå svensk standard har genomsyrat hela processen. En annan viktig punkt vid framtagandet av Katastrofsjukhus har varit konstruktionens vikt, vilket är tältsjukhusens största fördel.

The number of people of getting allergic symptoms is increasing and the reasons are considered to be many. The human have changed their habits and spend more time indoor. In combination with new building technologies where denser housing constructions and new materials this causes bad indoor climate contributes to a higher occurrence of allergiesThere are several courses of action to deal with this problem. One action is by choosing allergy-free interior surface materials. An allergy-free material emits low concentrations of harmful substances resulting in a great indoor air quality.

En säker bakteriediagnostik kräver en korrekt provtagningsteknik, ett lämpligt transportsätt och rätt odlingsteknik. På grund av centralisering av verksamheter och ekonomiska begräsningar, är transport av prover till mikrobiologilaboratorium mycket vanligt. Detta medför behov av ett transportmedium som håller känsliga bakterier vid liv under långa transport- och förvaringstider. Dessutom skall transportrören klara av maskinell utodling som kräver ett vätskebaserat provtagningsmedium. Denna övergång minskar även arbetsbelastning och förbättra ergonomin hos personalen.

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

Septic tenosynovitis involving the digital sheath is a relatively common problem in the horse and the prognosis has been considered as poor. However, there are only few studies confirming this. The purpose of this study is to increase the knowledge about the prognosis for septic tenosynovitis in the digital sheath. The literature indicates that half or a bit more than half of the treated horses will return to previous use. The recommended treatment is debridement of the wound, lavage and sometimes application of drains and broadspectrum antibiotics. The prognosis is considered as worse when the infection is established.

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.

I want to find the meaning of food ?potato in today?s society. How about marketing and how does potato consumes? What can be done to achieve better competitiveness towards other products now and in the future? I will build this project on a statistic ground ?now and then? as well as a study to people outside various food- markets. The consumers answers will state my foundation in this project.

Otitis externa is a disease regularly encountered in veterinary practice. It is estimated to be the most common disease in the external ear canal of dogs and treatment is often delayed due to unfortunate pet owner ignorance. Owners tend to assume that scratching of the ears and head shaking are natural behaviours in their dog and may be neglecting the problem unknowing of how severe it actually is. A literature study has been carried out to examine the causes of otitis externa in order to present a collection of measures that can be used in the treatment and prevention of the disease. In turn these measures can be advised to the dog owner and used in the home environment to make the best qualifications for healthy ears in the dog. The causes of otitis externa have been divided into predisposing, primary, secondary and perperuating causes.
