I vilken utsträckning kan hästar enbart utfodras med grovfoder?
Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.
Skriv- och läsundervisning i år 1 : En pilotstudie utifrån Aristoteles kunskapsformer
AbstractThis work is a pilot study intended to show what an experienced teacher of Swedish in first grade teaches and how she teaches. A further aim is to test methods for the analysis of Aristotle?s forms of knowledge in order to elucidate the teaching of reading and writing. As regards theory, the study proceeds from rhetoric and its doctrine of forms of knowledge according to which the whole in communication consists of episteme, techne and phronesis. The methods involve analysing the content of the communication and analysing speech acts, rhetorical figures and paralinguistic expressions.
Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan
The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.
Svensk dagstidningsbevakning av klimatförändringar : En flermetodsstudie med tyngdpunkt på aktörernas roll

Focusing on both what kind of messages the organizations publish, and what kind ofmessages engage the organizations? followers. This is achieved by quantitative content analysis:categorizing messages into the categories Information, Community and Action, and measuring whichof these categories got the most shares, comments and likes.
Varning! Effekter av varningar i printreklam.: Effekter av varningar i printreklam
The purpose of warning labels used by governments is to decrease consumption. In Sweden, the mandatory warning labels are designed according to statutory guidelines, and not according to research on attention-grabbing graphic elements. This results in a belief that the attention toward the warning labels is poor. An extensive experiment underlies this study, which has the purpose of providing insights to the effects that warnings, warning design, and warning content has on attention, attitudes and behavior in print ads. The study shows that, even though the standard design and content has lost much of its potential to communicate the warning, it gains more attention compared to a warning label with new design and content.
Magasin för lagring av vatten och växtnäring
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Urea som kvävekälla till växande ungnöt
The purpose of this study was to examine whether urea could be an option as a nitrogen source for young cattle, the study was limited to risks related to feeding, growth and feed efficiency. Microbes in ruminants have the ability to convert nitrogen to protein, this has been highlighted by beef producers as they are in search of cheap protein feed resources. Urea can be a worthy source of nitrogen for growing young animals, because of its high nitrogen content and the low price. Studies have shown that the replacement of a portion of the total protein content by urea in diets with low content of crude protein, like corn silage, may improve animal growth and feed efficiency. Replacement of all the true protein with urea can result in reduced feed intake and microbial growth.
Erfarenheter från Olika Produktutvecklingsprocesser vid Utvecklingen av en Atmosfärisk Vattengenerator
This Master of Science thesis was completed at the Department of Machine Design at the Royal Instituteof Technology in Stockholm in collaboration with Lund Faculty of Engineering, Luleå University ofTechnology and Stanford University. At Stanford University a global product development project wasrealized as part of the course ME310. The project was initiated by the American company ImmerseGlobal whose vision was to develop a new type of Atmospheric Water Generators, a machine that absorbsthe moisture in the air and via a water system transforms it to pure drinking water. The project was partlyfinanced by the Product Innovation Engineering program, a Swedish research and development programfor increased innovation capability in organizations.In parallel with the global project in the ME310 course the product development process was studied inorder to compare it with a product development course at the Royal Institute of Technology, IPU. Thetwo courses are similar to each other in several aspects.
Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor
The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Studier av koppar i mjölk : en prooxidant med negativa effekter på mjölkkvaliteten
The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.
Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :
Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.

Spelutveckling och lansering av applikation till Android
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Veckorevyn på papper och webb : en kvalitativ undersökning av tidskriften Veckorevyn och dess motsvarighet på nätet
Purpose/Aim: The aim is to examine the cooperation between the magazine Veckorevyn and its Internet based counterpart, veckorevyn.com. The purpose is also to see if veckorevyn.com is taking advantage of Internet and its possibilities.Material/Method: There are two qualitative methods used for this study: interviews and a three-pieced content analysis. The material analyzed is the magazine Veckorevyn (number 25/2008) and the website www.veckorevyn.com during a two week period.Main results: The study shows that Veckorevyn and veckorevyn.com have several differences, but also some similarities.
