Fröplacering vid hög såhastighet - Väderstad Rapid jämfört med Amazone Cirrus

In today's agriculture efficiency and the capacity of tools and machinery are crucial. In this work we investigate whether it is possible to enhance the capacity of sowing by increasing the work speed of seeders, how seed technology affects seed placement, and if there is any difference between two different brands of seeders and their sow techniques. The seeders we have chosen to compare are Väderstad Rapid drill and Amazon Cirrus drill. The tillage capacity of the seeders and their traction power needs were examined as well.Väderstad Rapid and Amazon Cirrus were tested in a randomized block design with four replicates at three different speeds, 8 km/h, 12 km/h and 15 km/h. The seed placement at the different speeds was examined by dividing the seedbed into four different zones from its surface to its bottom.

I gränslandet mellan not och ton : - notbilden i nykomponerad musik

This thesis is about the interaction between composition, notation and interpretation and what occurs between the fields with an extended notation.The purpose of my thesis is to examine the possibilities tothoroughly describe and map the sounding samples through composition prototypes.The thesis has a qualitative approach, and the empirical material consists of different documents about notation and from interviews with musicians and students about the instruments used in the thesis.It also consists of 17 compositions recorded at Örebro University School of Music as an appendix.The analysis shows that the context in which the symbols are found, play an important role in performing them. It also shows that the performers are rooted in a traditional way of performing..

Analys och förbättring av en mätenhet för laddning av elfordon

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

En jämförande studie mellan kreatininkoncentration i serum och GFR mätt med scintigrafi hos hund med misstänkt kronisk njursjukdom

Both serum creatinine and measuring GFR can be used to evaluate renal function in dogs suspected to have chronic kidney disease (CKD). Although high creatinine levels usually indicate renal disease, normal creatinine levels can be present in dogs with decreased renal filtration. Measuring GFR is generally believed to be the most accurate way of detecting decreased renal filtration and scintigraphy GFR using 99mTc-DTPA has been found to correlate well with the ?gold standard? inulin clearance method.When measuring GFR by scintigraphy, 99mTc-DTPA is injected intravenously and radioactive decay of technetium gives rise to gamma radiation, which is registered by a gamma camera. Pictures and curves of radioactivity in the kidneys are generated by means of a computer program.

Design och konstruktion av mätuppställning för induktiv mätning av magnetisk spinndynamik

Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

Evaluation of Different Extraction- and Analysis Methods for Calprotectin in Feces

Background Calprotectin is a protein expressed in the cytoplasm inside the neutrophile granulocytes. During inflammatory bowel disease (IBD), the neutrophile granulocytes are involved in a complex interaction at the inflammatory area where they die and release their content into the intestinal lumen. Therefore, calprotectin in stool is a suitable marker for diagnosis and measurement of the disease-activity in patients with IBD. The most commonly used method to detect calprotectin in stool is ELISA, but the process of manual preparation of stool samples is time-consuming.Aim The objective of the study was to evaluate an extraction method that could replace manual preparation of fecal samples and to compare different methods for measuring Calprotectin in stool using two ELISA-methods from two manufacturers and one rapidtest.Methods For extraction of calprotectin from stool samples we used sample collector tubes from Epitope Diagnostics and fecal preparation kits from Roche. Two different ELISA-kits for measuring calprotectin concentration in stool were compared.

Optimering av distorsionseffekt med hjälp av Fourieranalys

In music performers and music-making are oftenused different distortion effects to give the desiredcharacter on the individual sound sources andinstruments. These have different names (fuzz,distortion, overdrive) depending on the character. Tocarry out this work, an extensive literature study ofthe circuit diagrams of a large number of the classicdistortion circuits implemented. In this work, adistortion effect of the character fuzz was createdfrom several other existing effects. MeasurementsFFT, frequency response have been conducted tovalidate the desired results along the given problem.The finished effect was named Instant Carlos and aprototype was manufactured.

New public management från solidaritet till effektivitet

The public service within health and care has changed remarkably during the last 30 years. It has been inspired by management ideas from profit-making businesses. Those thoughts are an umbrella term called Nex public management. In what way has New public management influenced the public service in Sweden? Important concepts in the change of public service are quality, effektivity and goals.

Processdatorsystem för tryckreglering

The task of this project was to build an computer processing system for pressureregulation, in which the pressure loss over the open hydrolicvalve should be kept as low as possible. By using an cross connected proportional directional valve the valve problem could be solved. The control- and regulationproblem for the pressureregulation system was solved by using the DAQ- card NI6035E from National Instruments and the computerprogram Automatic Pressure Control 1.0 which has been software developed and written in Visual Basic. The final result showed that correct processvarible was obtained in 0,5 seconds, when the setpoint was changed in the testarea 0 - 2,5 MPa..

Bestämning av vattenytor med hjälp av Nätverks-RTK och totalstation : Inmätning av Karlbergsån i Grums kommun

This report is presenting an approach that can be used to measure water surfaces in difficult conditions caused by dense vegetation and lack of nearby known points. The objective was to make a contribution to necessary measures for adaptation against floods in Grums Municipality along the stream Karlbergsån, which may occur when persistent rain raises the level of the stream. Along the river there are low-lying areas prone to flooding. According to Grums Municipality, the stream may widen where the water level differences are large, to create a better flow path and to counteract flooding. Grums Municipality was also interested in survey stormwater discharges which may affect the water level in the stream.

Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

Nutrition and health claim labelling of food: Understanding the unique relationship between consumers, companies and legal instruments involved

Problem formulation: Recent results from the European Food Information Council?s consumer research on nutrition information and food labelling revealed that most consumers have little understanding of the nutrition information found on food products, feel that there is little authority regulating these matters and wish for a more trusted source of information and regulation and lastly it was found that consumers accept their limitations and have little motivation to even read or learn about nutrition information. Thus what are the reactions of the various legal authorities to this problem? How are food retailers and producers responding to the needs of the consumer? How are consumers then reacting to these two players in the industry and the changes they are making?Purpose: The purpose of this research is to gain new perspective and a better understanding of relationship between consumers, companies and legal instruments in relation to nutrition and health claim labelling of food products. Method: The nature of this multi-disciplinary research has led to the study of all three areas, business administration (containing consumer behaviour) and business law, which are contained in this paper.

NUDGING Kan nudging leda oss till att äta mer klimatsmart - Ett empiriskt experiment på IKEA med syfte att få restauranggästerna att äta mer vegetariskt

Food consumption generates externalities such as carbon dioxide emissions, which contribute to global warming. The principal issue is that emissions are not covered by the "polluter pays principle". For this reason, new policy instruments need to be tested and implemented to correct the externalities. In food production, beef and dairy production has the largest environmental impact in terms of carbon emissions. As food is a necessity, simply reducing production will not solve the problem.
