Människans näringar och kulturer har orsakat landskapsförändringar som på många håll i världen lett till flera ekologiska konsekvenser som erosion liksom övergödning av vattendrag och hav. Skogsbruk såväl som jordbruk har därutöver resulterat i stora utarmningar av den biologiska mångfalden på jorden. Sedan en tid har jordbrukets negativa konsekvenser fått alltmer uppmärksamhet inom bland annat politik, forskning och näringsliv, varav somliga människor aktivt försökt stoppa det negativa händelseförloppet som manifesterat många av världens odlingslandskap. Diskussioner som innefattar ekosystemet och dess så kallade tjänster för människans såväl som andra organismers överlevnad och välbefinnande erhåller därutöver mer och mer fokus i strävan mot miljövänligare alternativ för storskalig odling. I sökandet efter mer ekologiskt sunda odlingssystem har intresset igen väckts för agroforestrysystem, som kombinerar vedartade växter med vanligt förekommande grödor. Etableringen av lähäckar på respektive intill odlingarealer i Skåne kan bidra med flertalet ekosysystemtjänster vilka bevisats stoppa ex.

The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.

This study is an evaluation of the runtime watch function in a OEE software, knownas ProTAK. OEE stands for Overall Equipment Effectiveness, it?s a way to measurethe factories process efficiency. The runtimewatch function allows the user to setup and monitor certain critical objects that are of importance for the pulp and paper process at the mill. The data from the runtimewatch can be correlated towards the suppliers specification for the components.

When a company in the manufactory industry makes costly investments, it's important that these are used as much as possible. The company in this case claims that their invested robot cell, with CNC machine isn't used enough. The questions here are: How can we improve the use of the robot cell? Which products are appropriate for the production in the robot cell? As a method to come to a conclusion, an analysis has been made over the manufactured products. And also interviews with machine operators and the production management.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.

Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

In this project, an area in the small town Tungelsta south of Stockholm, is in focus. Tungelsta is placed in the municipality of Haninge and it is for the planning department on the municipality, this project is made. The task is to compose an arrengement of buildings and open spaces for a 50 hektar area. Today the area is consists of agriculture fields and forests. The area is placed near the railway station, in the city centre of Tungelsta, which makes it interesting and important to work with. There are different opinions about the future plans for the area.

Being a patient in intensive care can be experienced terrifying. Studies have demonstrated the link between unpleasant memories of hospitalization in the ICU and the development of posttraumatic stress disorder, depression, anxiety, and perception of quality of life in its aftermath. Placed on a ventilator, the patient is exposed to multiple invasive procedures. The aim was to describe critical care patients' experience of being intubated or tracheostomated. Method: Literature review using conventional content analysis.

Many jobs in rural areas have historically been linked to the agricultural sector. The restructuring that has been implemented in agriculture has resulted in a significant reduction in the number of jobs in rural areas. A consequence of this is that many people have moved to cities to earn a living. To maintain a living countryside in Sweden, it is therefore essential to create alternative livehoods in rural areas. An industry that can have a major impact in the future is rural tourism.

Electrolux Laundry Systems is the world leader in manufacturing professional laundry equipment.The machines are used in the hotel sector, elderly care, in multifamily houses, laundry bars, and incommercial and institutional laundries.If there is oil or grease left in the clothes after washing may the heat from the dryer cause a chemicalreaction. This reaction may, under certain circumstances cause a fire inside the drum. Competitors toElectrolux has developed its own systems that extinguishes fire inside a tumble dryer and customershave expressed desire to purchase a fire-extinguishing system. Therefore, the project team receivedthe task by Electrolux to develop a fire-extinguishing system that extinguishes a fire in a tumbledryer.The purpose of the project has been to develop a system that both detects and responds to fire in anindustrial tumble dryer to meet the competitors and to satisfy customers' requirements.The goal was to develop a fire-extinguishing system for Electrolux Laundry Systems and develop afully functioning prototype.The project began with information searches on a variety of methods to both detect and extinguish afire. Subsequently, a number of different methods were used to develop a final solution and make aprototype.The result of the project is a fire-extinguishing system that extinguishes a fire inside a dryer.

The measuring of logs is important in the sawmills process to the sawn products. The technology of automatic wood measurement is continuance developing. This study has the purpose to see how the different techniques and the routines works of measure frames for determining of wood value and sorting in sawmills. The study is performed as a literature study and a survey. The survey includes some of the Swedish sawmills that produce more than 10 000 cubic meters sawed products per year.

Surgical site infections are a recurrent problem in veterinary medicine. A 2-5 % infection rate in clean surgery has been reported. During the last years the increase in methicillin resistant staphylococci has also taken its toll on veterinary medicine, demanding a stricter hygiene and antibiotic regime. The 2008 outbreak of methicillin resistant Staphylococcus aureus (MRSA) at the University animal hospital, Swedish University of Agriculture indicated that that the MRSA problem was now a real, possibly zoonotic problem.Since the first dog, in Sweden, was diagnosed as a carrier of methicillin resistant Staphylococcus pseudintermedius (MRSP) in a study in 2006, the infection rate by this bacterium has increased. In 2009 (January 1st - December 2nd) the National Veterinary Institute (SVA) has identified 58 samples as MRSP positive.
