Grassland is a great part of Swedish agriculture and there is a demand of what the grassland yield is in practice. To be able to control the economic of the milkproduction it is important for the farmer to know how big quantities of pasture there is to use during the year.The work is based on interviews of 22 farmers from southern part of Sweden. Their area of grassland fluctuate between 16 up to 360 hectares. The questionnaire content 32 questions.The most common way to weight the green plant material is to drive over a scale, and to measure the dry extract with your own gauge. It takes in average two minutes toweight one load of green plant material.

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

The possibility for plants to utilize phosphorus in soil is a prerequisite for conducting agricultural production, both small scale and professional. Spreading of phosphorus fertilizers and manure is therefore seen as a necessity in today's agriculture in order to achieve high yield. Manure management, livestock farming and manure storage could contribute to the eutrophication of lakes and rivers. For instance, when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management.In the municipality of Växjö there is still many bodies of water that do not reach the Swedish environmental water quality standard of "good ecological status". This thesis has therefore analyzed the manure management and storage on agricultural farms which may have contributed to eutrophication in the municipality.The method for this thesis was a literature study, a questionnaire survey with 820 receivers and a summary of issued inspection reports from 2013.The results highlight the ways in which agriculture may have contributed to the eutrophication of lakes and streams in the municipality of Växjö.

The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.

The chow-chow breed is considered to have a low fertility and this report is an in depth study of the reproductive functions of this breed in Sweden. Only 53 % of the Chow-chow matings results in litters. Previous studies of other breeds in commercial kennels shows mating results around 85-90 %, but this has not been investigated in hobby kennels and most Chow-chows which are bred from in Sweden, are kept as family pets. Contrary to most other breeds, Chow-chows show a seasonal reproductive pattern and most litters are born in the autumn. The influence of the month of mating on pregnancy rate and litter size was found to be not significant, but can be considered a trend. Thirty-nine females with previous known fertility problems where studied. Some of them had reached puberty extremely early, at an age between 4-5 months, and many of the bitches showed great fluctuations in intervals between oestrus cycles. Some of the females showed abnormalities such as very short oestrus intervals of only 2-3 months, probably without ovulating.

A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to provide interactive real-time animation and visualisation of the simulation results. The work focuses on two themes and the integration of them. The first theme is the storage and management of the large data sets produced.

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.

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

In Sweden the climate makes it impossible to feed fresh herbage to cattle during many months of the year. During periods when preserved forage must be supplied it is important that this forage is stored in such a way that high quality is retained, both nutritionally and hygienically. Furthermore, it is essential that losses occurring when handling and storing the forage are kept as low as possible. This study compares storage in tower silos, bunker silos, big bags and bales,estimating dry matter losses as well as losses in metabolizable energy and crude protein that occur during storage. The results show that tower silos, bunker silos and big bags, the systems with the largest amount of forage and a long feed out period involve larger losses than bales, which are fed out immediately after being opened. As the feed out rate influences the losses, tower silos and bunker silos should be used during the period of the year when the feed out rate is as high as possible, i.e.

GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company.
