Komfortsanalys med hänsyn till vibrationer orsakade av människoaktiviteter. : Ett modernt dimensioneringsproblem för huskonstruktörer

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system

The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991). A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations. Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012). Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).

Sjuksköterskans upplevelser och attityder av omvårdnadsarbetet med kvinnor i samband med abort samt vilka faktorer som påverkar dessa : En litteraturstudie

Bakgrund: Abort innebär att graviditeten av olika skäl avbryts. En abort kan vara spontan eller inducerad, och den kan ske antingen medicinskt eller kirurgiskt. Sjuksköterskans roll vid en abort är att stötta kvinnan genom hela processen.Syfte: Syftet med studien var att undersöka sjuksköterskans attityder och upplevelser av omvårdnadsarbetet med kvinnor som genomgår en abort samt vilka faktorer som påverkar dessa.Metod: Studien är en litteraturstudie med deskriptiv design. Studien är baserad på 13 vetenskapliga artiklar som har sökts fram genom databaserna Cinahl och PubMed.Resultat: Denna litteraturstudie visade inte på några entydiga attityder hos sjuksköterskan vad gäller abort. Sjuksköterskan kunde känna skuld, depression och skam.

Problematiken vid samägd jord- och skogsbruksfastighet : De rättsliga förhållanden

The purpose of this thesis is to investigate and analyze existing law concerning joint owner-ship in agriculture and forestry businesses. Joint ownership often arises through a succes-sion of ownership, therefore we will go through the most useful methods.Even if the owners of agriculture and forestry businesses are getting older, the numbers of succession of ownerships are still low. A succession of ownership is important to plan and its time is demanding. Often it takes three to five years for the completion of a succession of ownership. Therefore, owners must start their planning in time and think about what is to come of their business.

Kvinnors upplevelser av stöd från vårdpersonal i samband med hemabort

Syfte: Syftet med denna studie var att undersöka kvinnors upplevelser av stöd och bemötande från vårdpersonalen i samband med hemabort.Metod: I studien har en kvantitativ, deskriptiv, komparativ tvärsnittsdesign använts. Urvalet skedde konsekutivt och som datainsamlingsmetod användes ett frågeformulär. Utifrån detta frågeformulär utfördes telefonintervjuer med studiedeltagarna.Resultat: Nästan alla kvinnor som deltog i denna undersökning tyckte att de fått bra stöd från sjukvårdspersonalen i samband med hemabort. Det fanns inga skillnader i upplevelsen av stödet beroende på kvinnornas ålder eller om kvinnorna hade tidigare erfarenheter av abort eller barnafödande. Angående andra upplevelser vid hemabort relaterade till det upplevda stödet från sjukvårdpersonalen visade denna studie att de flesta var nöjda med den information de fått beträffande abortprocessen, normal blödning i samband med abort och smärta.

Test av immunohistokemiska markörer för differentialdiagnostik mellan Spitz nevus och melanom

Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.

Ledarskapets påverkan på framgångsrik organisationskultur

Denna studie undersökte organisationskultur och ledarskap på ett av de mest framgångs-rika företagen i Sverige, W.L. Gore & Associates Scandinavia AB (Gore), där organisa-tionskulturen sägs vara grunden till varför de har vunnit pris för Sveriges bästa arbets-plats två år i rad. Gore är en ledande tillverkare av tusentals produkter inom textil, indu-stri, elektronik och medicin. Organisationens mest kända varumärke är GORE-TEX®, som bland annat används i skydds- och sportkläder (Gore 2011a, Hamel, 2008; My-newsdesk, 2011). Denna studie syftar till att kartlägga vilka organisationskulturella framgångsfaktorer som finns representerade i Gores organisationskultur samt om det finns ett samband mellan dessa faktorer och ledarskapet på Gore.

Djurvänlig hantering av lantbrukets djur i samband med transport

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.

Produktionseffekter och behov av dikesrensning i Sveaskogs skogar :

Ökad efterfrågan på virke har lett till ett ökat intresse för och användande av olika produktionshöjande åtgärder. En sådan åtgärd är dikesrensning som innebär att befintliga diken eller dikessystem rensas för att de skall bibehålla eller återfå sin ursprungligt avvattnande och produktionshöjande funktion. Sveaskog avser att öka omfattningen av dikesrensning. Därför behövs en kartläggning av behovet på deras marker. På samma gång behöver produktionseffekterna och livslängden på dikena utrönas. Studien genomfördes via en studie av befintlig litteratur om skogsproduktionseffekter efter dikesrensning och dikning samt förfall och livslängd hos diken.

Leaf structure and localization of a transgene protein in barley

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Transportekonomi : Underlag för prisförhandlingar

The report addresses four main tasks, situation analysis of the company's total costs and transportation volume, cost analysis associated with the adjustment of the filling ratio, transport costs for the expansion and new expenses on a combination of expansion with new adjusted filling ratio.  Increasing transport costs for the company was the main reason for the request of the current situation analysis. A survey of the total cost with the actual volumes and transport provider pricing is the basis of the analysis that extends from May 2006 to October 2008. The results show an increase in costs, both overall expense and per cubic meter of transported goods. Volume spreads, trends, and seasonal variations are according to our and the company?s expectations.

Inflammatory cytokines induced by Bovine Viral Diarrhoea Virus (BVDV) in Peripheral Blood Mononuclear Cell (PBMC) subsets

Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.

Abort : Sjuksköterskors upplevelser vid avbrytande av graviditeter inom gynekologisk vård

Bakgrund: Internationellt existerar fortfarande illegala aborter med kvinnans hälsa, och i somliga fall liv, som insats. Inom gynekologisk vård i Sverige arbetar allmänsjuksköterskor vilka vars arbetsuppgifter bland annat består av att vårda kvinnor som genomgår inducerade aborter. Deras arbete vilar på den svenska abortlagens bestämmelser om kvinnans rätt till fri abort samt den övergripande hälso- och sjukvårdslagen. Allmänsjuksköterskor har fått en mer framträdande roll i arbetet med inducerade aborter i takt med den ökade användningen av den medicinskt inducerade aborten. I sitt arbete ställs sjuksköterskorna inför specifika arbetsuppgifter vilka kan tyckas påfrestande.
