Etablering av höstvete med reducerad jordbearbetning :
The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing.
I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.
Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring
The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.
Incidenthantering i molnmiljö
Incident response plans are faced with new challenges as organisations expands to the cloud, this thesis aims to highlight these challenges and their potential solutions. Our work has focused on managing the incident response in contrast to earlier work that has been focusing on preventing them.As with any development, security is seldom prioritized. Instead the focus are often aimed towards usability and functionality, which means incident response plans are written, implemented, forgotten and finally becomes obsolete. This could result in an organization losing their ability to produce acceptable forensic images, avoid severe downtime, or prevent similar incidents in the future, which are all important parts of incident response.Traditional incident response plans does not address incidents in the cloud. Thus, an absence of guidelines for managing incidents in the cloud becomes apparent.
Metanpotential för alger och bioslam blandat med pappersfiber
In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.
Vaccination against boar taint - effect of restrictive and semi ad libitum feeding regime on production and behavior
Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.
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.
Varmsmidning av aluminiumlegering 6026 T9 : Warm forging of aluminum alloy 6026 T9
In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.
Utvärdering av amningsstrategi : - Vårdprofessionernas perspektiv
Research show evidence for benefits of breastfeeding and that infant-feeding-plans are supportive. Family-centered care is the theoretical framework. Family support is crucial for successful breastfeeding. It is important that society creates opportunities for mothers to breastfeed and contribute information and support by healthcare professionals. The aim of this study was to evaluate how the midwives and child healthcare nurses found that the newest breastfeeding strategy influenced their breastfeeding- and rearing support in the County of Jönköping.
Brunstbeteendets relation till gyltans intag av genistein
Many scientists agree that phytoestrogens could have an effect on the reproduction of an animal. The question is now why and what mechanisms that play an important role. This paper has been focusing on the estrus behavior of gilts by use of a behavioral study. Some of the gilts were given additional feed with the phytoestrogen genistein which commonly occurs in the feed as a part of soybean products. Blood samples were collected and analyzed for progesterone and estradiol concentrations.
Effekter av bearbetningsdjup i plöjningsfri odling
In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues.
The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies.
There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.
Utvärdering av sökmaskiner - en textanalys kring utvärderingar av sökmaskiner på Webben
The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.
Effekt av utfodring och motion för utveckling av diabetes mellitus hos gråhund och jämthund. :
This study is a follow up of a pilot study made 2004, that evaluated feeding, exercise and weight as possible risk factors for developing any kind of diabetes in dogs. We have selected our material for a certain kind of DM that exists among Norwegian and Swedish elkhounds. These breeds are among the most common breeds affected by diabetes and this kind of DM almost exclusively affects intact bitches.
We performed a case- control study where the owners were interviewed over the phone. The owners of a total of 48 case dogs and 58 control dogs were contacted. The questions for the cases focused on the time before the diagnosis and the questions for the control dogs focused on the dog´s adult life.
Teknik i förskolan och grundskolan : En studie om hur pedagoger arbetar med teknik i de tidigare åldrarna
AbstractIn this study. I have compared four different schools, two preschools and two compulsory schools. My purpose has been to get a view of, to which extent they use technology in their education.I have also compared boys and girls.The result has been achieved with the aid of questionnaires.It shows that the pedagogues in the preschool, think they use technology every day. They use it in their games, experiments, food situations and even when the children are dressing them selves.The pedagogues in the compulsory schools work with technology, without reffering to the actual concept. They use the nature and experiments, to involve the children in technology.One of the schools has a film project.
Kan ät- och liggbås påverka kornas välbefinnande?
The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
