Potatisens specifika vikt och kokegenskaper med hänsyn till odlingsplats och sort :

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

Utvärdering av Near Field Communication och Certified Wireless USB: Säkerhet vid utveckling av applikationer

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

Så nås samstämmighet mellan logistik och företagsstrategi : en analys av hur den logistiska strategin ska utformas för att stödja företagets överordnade strategi

Background: Due to an increasing globalization the competition has increased and this has lead to overcapacity and falling prices on markets today. The subject field logistics has during the last decades been given increasingly significance and has become a way to handle the competition. Theories clearly point outthe importance that a concordance exists between logistics and superior strategy but few, if any, authors give further details about how this adjustment should be made. Purpose: The aim of this thesis is with a case study approach survey if the subject field, which describe the importance that logistical solutions correspond with the superior strategy, is known and implemented in a company. We aim to develop the subject field through our empirical findings.

Att mötas i en vitlökspress - en studie om korpus

 My field is Korpus and in this project I am investigating what role that plays for me as an artist connected to craft. To really get close to, and understand Korpus I have deconstructed it to find clues to why the silversmithing field looks like it does and how we got here. I believe Korpus has not yet come out of the closet for what it really can be. That it carries a great heritage of traditions and preconceptions that it would do well to shake off a little bit of. Can Korpus as an art field really survive in Sweden, where the Church has no power and silverware is no longer a need to demonstrate ones economic prosperity at an important dinner party? To help myself get closer to these objects I have given my own definition of Korpus.

Kontrollerad gjutprocess för renare stål

In a multi-year project at Swerea Swecast AB studies on influence of dissolved gas on inclusions have been made. The knowledge about these parameters could be used to increase the quality of the final steel casting. The purpose of this thesis was to closer examine the impact of the oxygen level on inclusions.The questions asked were:? What was the amount of inclusions at different levels of oxygen?? What was the size of these inclusions at different levels of oxygen?? What does the inclusions consist of at different levels of oxygen?This was studied by measuring and sampling, sample preparation and microscopic analysis using an optical microscope and a scanning electron microscope (SEM). Measurements and sampling was performed at Smålands Stålgjuteri AB in Eksjö and at Swerea Swecast AB in Jönköping.

Måltidsmönster, kost - och - medievanor bland överviktiga 15-åriga flickor och pojkar

Objective: The aim of this study was to compare equations used to calculate BMR to values of BMR obtained from measurements in order to determine the most suitable equation to be used on children and adolescents with CF.Design: The participants where children and adolescents with CF. Data was collected from the division of Clinical Nutrition at Uppsala Akademiska Sjukhus. Age, weight, height, BMI, BMR, FFM and FM was recorded from 27 measurements. BMR from the participants collected from the indirect respiratory calorimetry was compared to the results obtained from five equations used to obtain a calculated value of BMR.Results: Tverskayas equation was best correlated with the measured BMR for the whole group. The equation underestimated BMR for the participants with a measured BMR over 1400 kcal/24h and overestimated BMR for participants with a measured BMR under 1400 kcal/24h.

Analys av instyrning och rolldynamik

When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

Varierad kaliumgödsling i potatis : en fältstudie i Hedemora

Variation in tuber quality within a single field was one of the motives for a pilot study in Halland, in south-western Sweden conducted during 2002. Quality problems in potatoes have been increasing due to the aggregation of several small fields with different land use history into larger farm units, which are heterogeneous in soil properties and fertility. The study in Halland indicated that both the uniformity and the mean size of tubers may increase from site-specific K fertilization, whereas total yields may be unaffected. The results from this pilot-study with site-specific fertilization showed that tubers reached a more uniform quality and gave a more uniform mean size, while the total yield wasn't affected at all. Site-specific K-fertilization has been applied for some years in Halland with good results. The aim of this study was to test this technique in another potato growing area.

Omvårdnad för kalvar med lunginflammation

Pneumonia is a common disease in calves. There are several causes behind the disease. The main purpose of this litterary study was to estimate what kind of nursing calves with pneumonia could benefit from, especially the evidence-based nursing recommendations for the sick calves. A further purpose was to gain knowledge of different treatments of sick calves and what kind of practical measurements that are most suitable to use in the preventive work. The results in this study shows that there are only suggestions of nursing, rather than some actual evidence-based actions. The most important nursing actions is to isolate the calves with dyspnea, prevent or treatment of hypothermia, potential dehydration and malnutrition. It is also important to make sure to place the calf on soft and dry bedding.

Dygnsvariation av metanemission från en anlagd våtmark

The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.

Altmetrics, a subfield of informetrics, is still in development. The aim of this thesis is to explore; the significance altmetrics may have in the LIS field, and to define the new perspectives altmetrics offer in comparison to traditional metrics. The research questions are:- How can altmetrics affect research assessment?- How does altmetrics position itself towards traditional metrics?- How could altmetrics influence the LIS field?A qualitative content analysis was used as a method. The analysis of a sample of ten peer reviewed articles was based on a coding scheme with eleven codes.

Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
