Ett designprojekt med fokus på för tidigt födda barns emotionella behov i kuvös

Babies born prematurely are deprived of normal sensorimotor stimulation when placed in an artificial environment, the incubator. The aim of this project was to design a series of products that could promote the baby?s emotional and neurological development, and to facilitate parental bonding. The products designed in this project has a theoretical basis on the research available today on cognitive and emotional development in children born prematurely. They were developed in close cooperation with a group of parents and nurses in a neonatal intensive care unit.Presence is a product collection for developmental care, consisting of a mattress, a figure and a necklace. The mattress has vibration sensors that transfer the mother?s heart beat and speakers with recorded heartbeat and her voice.

Kvalitetsbedömning av selekterad och oselekterad hingstsperma med hjälp av flödescytometri och fluorometri, före och efter seminsäsongen :

Most Swedish Warmbloods are bred by artificial insemination (AI). Quality control of the semen consists of the subjective evaluation of motility. There is a need for a more accurate and objective method of rating the semen. In this study we compared fluorometry with flowcytometry as a method for evaluating sperm viability. Semen was collected from three stallions, stationed at Markebäcks Gård, Askersund, three times during week 15 and week 34, 2008.

Utvärdering av viabilitet hos selekterad hingstsperma med hjälp av fluorometri :

There is considerable variation between stallions in semen quality and fertility due to the fact that selection of stallions for breeding is not based on fertility or semen quality but on performance. The increasing use of cooled semen for artificial insemination has resulted in decreasing pregnancy rates. Therefore the equine breeding industry needs new methods for evaluation and development of sperm quality and fertility. This study is a part of such a project and is performed by SLU in cooperation with Flyinge AB. Ten stallions at the Flyinge National Stud were used in the study and three ejaculates were collected from each stallion.

Raä 977 - En lokal och tre aktivitetsytor. : En tvärvetenskaplig undersökning av Raä 977 vid Vojmsjön i Vilhelmina socken

This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.

Pinus contorta susceptibility to Heterobasidion spp. : a study of stumps, roots and artificial spore infections of stumps

The Lodgepole pines susceptibility to Heterobasidion spp. was investigated in three parts ofthis study. In the first part, discs from freshly cut stumps were collected and analyzed to seeif the fungi can spread and grow naturally in Lodgepole pine stands. In the second part, rootsamples were collected from Lodgepole pines planted in former infected Norway sprucestands to see if the fungi can spread through root contacts. For the third part, new stumpswas created and artificially infected with spores of both the S?type (H.

Personalen som påverkansfaktor : Vilken påverkan har personalen i en butik på kunden?

The store manager can make great benefits of having an eye on how the staff works towards the customer, because the personnel is an important tool when competing with other stores. This paper is focusing on the part that relates to the staff in the store, which is one of the key tools in the competition for customers after the customer made it to the store. Many stores have guidelines which the staff should follow when they meet with customers. If the staff is too tightly controlled by these guidelines, customers can perceive the first encounter with the staff as artificial and as if the genuine friendliness does not exist. It is important that the staff looks at the individual customer and treat every customer in a personal way and that the staff can see the customer?s needs.

Riskbaserat provtagningsprogram för mikroorganismer i Gäddviks vattentäkt

Risk-based sampling program of microorganisms in the water source in northern SwedenAfter several disease outbreaks caused by parasites in the drinking water during the last years, it is more essential than ever to insure that the water supply companies have enough barriers to counteract the presence of microorganisms in the outgoing water. It is also discussed whether climate changes such as increased precipitation can have a connection to the increased cases of parasites in water sources. The water source at Gäddvik is Luleå municipality?s largest and provides drinking water to 64 500 of Luleå?s 74 000 inhabitants. The investigation of microorganisms in the water source, especially in the Lule River has not been as prioritized as the sampling of chemical parameters.

Sjuksköterskans stöd till vuxna patienter med rheumatoid artrit - empirisk studie på reumatologmottagningar

Background: Rheumatoid arthritis is a common disease worldwide. The disease is described as a chronic inflammation that afflicts mainly the joints, the tendrons and the synovial joint. The inflammation breaks down cartilage, ligaments and bone. When the patient gets the diagnosis he/she frequently reacts with chock, denial or/and dissociation. Active support from the nurse can have an important impact on the patient in accepting and processing that he/she suffers from disease.

Myt och vetenskap om kastration av tik

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

VeckoRevyn ? din bästa vän i vått och torrt? : En kvalitativ undersökning om innehåll och tilltalssätt i VeckoRevyn.

?VeckoRevyn ? your best friend in good times and bad?? is a BA thesis based on a weekly lifestyle magazine, VeckoRevyn, with a female demographic aged 18-25. Issues of the magazine, published in 2009 and on, is analyzed and dissected to better understand and be able to get answers for the questions of issue. What is said in the magazine, and how does the message reach the audience? Furthermore, the message, as well as the tone used to convey it, is reviewed as part of the discussion about consequence.

Dikesavståndets inverkan på såtid och skörd

All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage. In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.

Inhysningssystem för växande ungtjurar

The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.

Byggnads- och investeringskostnader : Robotmjölkning eller konventionell mjölkning?

This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south of Eslöv in Skåne. While my family for some time have thought about building a new milkingstable with AMS(Automatic milking system) I decided to compare the AMS with a conventional milkingstable. We are abit concerned about how many cows we should have in the new stable. Because of that I calculated with two different number of cows. I have compared three different types of milking stables: One alternative is 180 cows milked in a double eigth hearing bone milking stable. The second alternative is 128 cows milked with two DeLaval VMS-robots. The third alternative is 171 cows milked with three DeLaval VMS-robots. One salesman from DeLaval and one salesman from A-betong helped me to get marketprices on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs labour is included. The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program with predicted costs. The calulations from the program showed that the price in the milkingpit system was 51 000 sek per cow.

Intelligenta System

Intresset för agenter som forskningsområde är någonting relativt nytt. Agenter i sig är en naturlig del av Artificiell intelligens men det är först på senare tid som de hamnat i fokus. Begreppet agent har spridit sig som en löpeld utanför AI-forskningen och kan hittas i många andra områden. Vad detta intresse för agenter kommer ifrån kan debatteras men det är troligtvis dels en följd av att internet visat hur kraftfullt ett distribuerat system kan vara, och att agenter och botar bokar våra biljetter samt söker igenom webbsidor åt oss.Arbetets huvudfråga är att undersöka hur ett intelligent system (för värmedistributionen i ett hus) kan uppnås genom att koppla ihop ett antal agenter med begränsade funktionalitet och distinkta uppgifter. Intelligensen i systemet ska uppnås genom samverkan mellan de olika agenterna.

Samband mellan digivning, avvänjning och mjölkens sammansättning med fokus på mjölkfett

Sammansättningen och kvalitén på mjölken som produceras är betalningsgrundande och därmed är det viktigt ur en ekonomisk synvinkel att producera mjölk som håller en hög standard. Syftet med denna litteraturstudie var att undersöka om samband finns mellan typ av digivning respektive avvänjning och mjölkens sammansättning. Fokus ligger på mjölkfettet samt fettsyrorna. De produktionssystem som tas upp är begränsad digivning och artificiell uppfödning. Begränsad digivning innebär att avkomman får gå med moderdjuret vissa timmar av dygnet fram till en senare avvänjning jämfört med artificiell uppfödning där avkomman skiljs från moderdjuret strax efter förlossningen.
