Asymptotically flat spaces are widely studied because it is one natural way of describing an isolated system in general relativity. In this thesis we study what happens to the Lanczos potential at spacelike infinity in such spacetimes. By transformations of the Weyl-Lanczos equation, we derive expressions for the limiting equations on both the timelike unit hyperboloid, and the timelike unit cylinder. Finally the Newman-Penrose formalism is used to get a component version of the equations..

The aim of this paper is to investigate to what degree the groups in our inquiry work independently. It is a qualitative research, which points to a well?functioning unit, that by definition is not self-governing, but has many traits of self- government. We have reached to the conclusion, that complete self?government does not have to be the best solution, if you want both quality and efficiency.

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.

Introduktion: Patientkontrollerad epidural smärtlindring (PCEA) är idag en vedertagen metod för postoperativ smärtlindring med få komplikationer. Försök har gjorts för att titrera fram den mest gynnsamma kombinationen med fokus på att maximera smärtlindringen och minimera sidoeffekterna. Syftet med studien är att identifiera smärta, sidoeffekter och behandlingstid samt patientens subjektiva skattning av smärtlindring vid postoperativ PCEA-behandling med bupivacaine, fentanyl och epinephrine.Metod: Studien är retrospektiv inkluderande 1088 patienter vilka postoperativt behandlats med PCEA och kombinationslösningen bupivacaine (1mg/ml), fentanyl (2?g/ml) och epinephrine (2?g/ml). Studien har undersökt skillnaden mellan kön, ålder och typ av kirurgi avseende smärta i vila respektive smärta vid mobilisering/hosta, infusionshastighet, givna och begärda bolusdoser, behandlingstid, sidoeffekter samt patientens subjektiva skattning av smärtlindringen.Resultat: Smärta i vila och vid mobilisering/hosta var under de studerade dygnen generellt låg, smärtan kulminerade under dygn 2.

This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems.        Not enough information about their freights. The transport planning unit in Malmö doesn?t have the exact delivery address when GP-Last begins to bring in the gods.        There are no clear routes.

Syftet med denna litteraturstudie är att beskriva hur sjuksköterskan kan identifiera postoperativ smärta hos barn och vilka omvårdnadsåtgärder som är adekvata vid smärthantering Metod: Artiklarna till denna studie är sökta i databasen Medline via Pub Med. Totalt 18 artiklar kvalitetsgranskades och analyserades. Resultat: Barn hade svårigheter med att uttrycka (dvs. sätta ord på) och särskilja vilka symtom som var de mest besvärande för dem under den postoperativa perioden. Gråt, skrik, jämmer och gnäll, verkade vara relaterade till barnens oförmåga att prata om smärta.

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

The purpose of this study is to find datable interstadial sediments in the core area of the LateWeicheslian ice sheet extent. Based on geomorphological evidence, three coring sites wereidentified close to the Ultevis plateau in Norrbotten, northern Sweden. Sediment coring wascarried out in two pre-Late Weichselian stream channels and in a sediment basin. Stratigraphyfrom one of the sites, a 100 meter wide meltwater channel, was chosen for further analysis. Thestudied core was 5,93 m long and ended in a lower till unit.

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

Syftet var att i en litteraturstudie undersöka eventuella hinder för optimal postoperativ smärtlindring av barn 6-12 år gamla samt undersöka vilka postoperativa smärtlindringsmetoder som används på barn 6-12 år gamla. Litteraturstudien bygger på elva artiklar som kvalitetsgranskades. I resultatet presenteras de faktorer som påverkar barns postoperativa smärtlindring i fyra kategorier: sjuksköterskans medverkan i barnens postoperativa smärtlindring, föräldrars medverkan i barnens postoperativa smärtlindring, barnens upplevelser av postoperativ smärtlindring och hinder för optimal smärtlindring. Resultatet av litteraturstudien visar att det fortfarande är svårt att smärtlindra tillräckligt då det finns ett stort antal hinder för den postoperativa smärtlindringen, exempelvis sjuksköterskors okunskap, otillräckliga ordinationer, tidsbrist och sjuksköterskornas bakgrundsfaktorer. Resultatet belyser även att föräldrarna har en stor del i barnens sjukhusvistelse och smärtbehandling..

The purpose of this literature review was to demonstrate the results of recent studies of the nurses ability to interpret younger childrens (0-6 years of age) experiences of pain in the postoperative stage. There is a lack of knowledge concerning young childrens ability to express themselves verbally and the nurse has to rely upon the parents knowledge about the child. Consequently, the teamwork between the nurse and the parents is of great importance in the care of the younger child. Therefore we intend to illuminate this aspect in this paper. This study aims to nurses of all categories, since patients with lack of verbal communication are frequently occurring.

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

This work has been done to develop a plan for a future dairy barn at theGästgivaregården and to show the space needed for cows and replacement heifers. Itwould also show the storage that will be needed. The design was largely based on resultsfrom studies on six different farms, but also the facts that are taken from research papersand articles in order to compare theory with practice. Because some farms only whereinterviewed by phone I have used a query form to obtain comparable resultes.The aim is to build a new barn with Automatic milking. I've drawn a milking stable for120 milking cow and replacement heifers with the capability to house up to 140 milkingcows if the farm would expand in the future.Calculations of feed amounts and space requirements have been made to see how manyhectares are needed to supply the cows and replacement heifers with feed and to knowabout what size of storage space is required.The investigations made in this writing are to answer questions about the AMS-unit`sposition and how to best maintain a good health status in the herd.
