Överlevnad och tillväxt för nyplantersade barrots- och täckrotsplantor : en studie av 42 bestånd i södra Sverige

The choice between bare-rooted and containerized seedlings in southern Sweden affects the investment costs as well as growth and survival. It is important to take these differences into account when choosing seedling type for reforestation. The most important differences between the two seedling-types is that bare-rooted seedlings has open root systems whereas the roots of containerized seedlings are grown in a container which may contain water and nutrients that are available for the seedling during the first period after planting. Moreover, bare-rooted seedlings are often older which results in thicker stembase and better resistance to attacks of pine-weevil (Hylobius abietis). In order to study differences in survival and growth between bare-rooted and containerized seedlings a survey study of newly planted clearcuts in south-western Sweden was made. In the study tree seedling types was included, one bare-rooted and two containerized with different ages. The population of pine weevils was probably low during the studied period which resulted in lower pine-weevil damage than normally found in this area.

Att delta och förändra, trots kaos! - En studie om Försäkringskassans organisationsförändringar.

Earlier the regional social insurance office was exposed to critisism because of bad administration and a lack of providing public service. Among other things the regional social insurance office was attacked because of long investigation hours and indinstinct working methods and was blamed for not being able to solve the unhealth in the society. This lead to the reformation of the previous regional social insurance office into a government authority agency on the first of Januari, 2005. Extensive organizational changes were made so that regional social insurance office could handle the demands and become a uniform public administration. I have made a qualitative study where the purpose was to se how the changes affected the public administrators and I focused on their participation and willingness to change.

Ultraljudssvetsning: ett komplement eller ersättning till symaskinen?

AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.

Balans- och benstyrketräning för personer i åldersgruppen 65 år och äldre i syfte att förebygga fall. - en litteraturöversikt

Bakgrund: Fall är den vanligaste orsaken till varför personer 65 år och äldre skadar sig. Orsaken kan t ex vara nedsatt balans- och benmuskelstyrka. Balans- och styrketräning för nedre extremiteterna kan avsevärt minska förekomsten av fallhändelser. Syfte: Syftet med litteraturstudien var att klargöra vilka metoder som används för personer i åldersgruppen 65 år och äldre med avsikten att förbättra balans, benmuskelstyrka, gång- och förflyttningsförmåga och därmed minska risken för fall. Metod: Litteratursökning utfördes i de medicinska databaserna PubMed, CINAHL och Proquest.

Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

MKB Vågade - igen?

Studien avser att belysa dels ett historiskt perspektiv hos MKB Fastighets AB:s organisationsförändring under Allan Karlssons ledning på 1990-talet, dels avser studien att undersöka hur dagens organisationskultur yttrar sig och dels hur den rådande kulturen förmodas integrera med en leanimplementering. Syftet är att utifrån dessa tre perspektiv skildra den rådande organisationskulturen samt genomföra en tolkning om organisationskulturen är enhetlig eller splittrad med existerande subkulturer. Frågeställningarna berör kulturen på 1990-talet, hur förvaltningsområdena framställs, respondenternas skildring av samhörighet och konsensus i organisationen, hur respondenterna ser på organisationsförändringen samt respondenternas syns på ledningen. Den teoretiska referensramen i studien lyfter fram vikten av att en organisationsförändring påverkar flera organisatoriska dimensioner. Organisationskulturen har makten att påverka organisationsförändringar och skapa inkonsekvenser som utvecklar subkulturer.

Att träna eller inte träna? : En enkätstudie om relationen mellan träningstyp, träningsmängd och skadeprevalens inom herrfotboll.

Bakgrund: Fotboll är en sport som präglas av knäskador, muskelbristningar och stukningar. Mycket fokus ligger kring hur man på bästa sätt kan undvika och förebygga att ens främsta resurs, spelarna, undviker att bli skadade och på bästa sätt kan producera resultat för klubben de tillhör. Studier har visat på att skadeprevalens är något som ökar i och med en ökad träningsmängd och att många skador är en följd av både muskelsvaghet och fel sorts träning. Många av dessa undersökningar menar på att man i dagsläget tränar fel och att träningen mer måste fokuseras på de fysiska krav som ställs inom den idrott man utövar, i detta fall fotboll.Syfte: Syftet med denna undersökning har varit att se om det finns någon korrelation mellan typ av träning, träningsmängd och skadeprevalens inom herrfotboll.Metod: Studiens syfte har besvarats med hjälp av en strukturerad enkät som skickats ut via en web-länk till aktivt fotbollspelande män. Undersökningen har involverat 100 respondenter från olika divisioner.

Framtidens stadsträd för en fungerande grönstruktur

The effect of climate change places demands on how we build cities. Cities have to be built denser to meet the objectives of sustainability but as a result of this densification city green areas are at risk of exploitationand disappearing. The question this raises is whether there has to be an opposition between a dense and a green city?Urban trees are playing a very important role in cities. They stand as the major part of the vegetation in citieswhich are otherwise dominated with concrete and stone.

Genetisk studie av inavel och fertilitet hos hund :

Inbreeding, the mating of related individuals, has been the one dominating breeding strategy for dog breeders during the last 200 years. However, its negative effects on fer-tility and other fitness traits, a phenomenon called inbreeding depression, have been ignored in the quest of perfect unity in conformation or performance. The purpose of this study was to test the hypotheses that litter size is reduced as a consequence of in-breeding, affected by both the inbreeding coefficient of the dam and the litter and that a rapid increase in the inbreeding coefficient affects litter size more than a slower rate. Data were collected from the Swedish Kennel Club registry of origin. Breeds included in the study were the Bernese Mountain Dog, the Cocker Spaniel, the Golden Retriever, the Rottweiler and the West Highland White Terrier.
