The efficiency of the newly launched predatory mite Amblydromalus limonicus : biological control of thrips in cucumber

In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been examined for its potential to use as a biological control agent in cucumber production. A. limonicus can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci. Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the southern part of Sweden. The basic control agent used against thrips was the predatory mite Amblyseius swirskii. In selected areas, additional A.

En kvalitetskontroll - Snustillverkaren Fiedler & Lundgren kvalitetstestas

This paper aims to describe the variation and develop a method to control the production for the product Metropol Kaktus from the snuff developer Fiedler & Lundgren. We are going to use the requirements from the product specifications as limits of the expected quality when we present methods to control the process. One method attempts to control during the process and the other attempts to maximize the number of products with strived quality before the process starts. Metropol Kaktus is a product produced with high quality, the mean weight is 20,023 gram and this is very close to the weight, 20 gram, which is reported in the product specifications. The variation in weight variable is less than what is reported in the specifications and the minimum weight is over the limit set by Livsmedelsverket.

Högskolestudenter och alkohol : Akademisk locus of control i förhållande till alkoholrelaterade studieproblem

Studenter är bland de som konsumerar mest alkohol i Sverige. Hög alkoholkonsumtion och extern akademisk locus of control (ALC) har liknande negativ effekter på studier. Denna studie undersökte relationen mellan alkoholkonsumtion, ALC och alkoholrelaterade studieproblem. 120 studenter, varav 91 var kvinnor, deltog genom att besvara en enkät bestående av The Academic Locus of Control Scale for College Students, the AUDIT Alcohol Consumption Questions och en egenkonstruerad skala som mätte alkoholrelaterade studieproblem. Data analyserades med en 2 (riskbruk/ickeriskbruk) x 2 (extern ALC/intern ALC) ANOVA för oberoende mätningar.

Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

Jämtländska pedagogers erfarenhet av att ta emot flyktingbarn i förskolan

In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.

Business Intelligence Access Control: Utvecklande av en behörighetsmodell för Business Intelligence

I dagens samhälle är majoriteten av våra tillgångar digitaliserade och bevarade i olika typer av informationssystem. Genom Access Control (sv. behörighetsstyrning) säkerställs att användare får korrekt åtkomst till dessa tillgångar. I takt med att organisationer genererar allt mer affärskritisk data i sina informationssystem har dock hanteringen av användare och behörigheter komplicerats. En modern genre inom begreppet informationssystem som länge visat ökad tillväxt är Business Intelligence (BI).

Quantification of Tripeptidyl-peptidase II : Optimisation and evaluation of 3 assays

Abstract Tripeptidyl-peptidase II (TPPII), is present in most eukaryotic cells. It cuts tripeptides from the N-terminus of peptides and is especially important for degrading peptides longer than 15 amino acids. TPPII also tailors long peptides into suitable substrates for the enzymes which transport and produce the peptides that MHC I present. Increased levels of TPPII have also been found in certain cancer cells, thus it is of interest to determine if TPPII could be used as a tumour marker.The aim of this study was to optimise and evaluate 3 different methods for quantifying TPPII. Western blot, enzyme-linked immunosorbent assay (ELISA) and fluorophore-linked immunosorbent assay (FLISA) protocols were optimised regarding incubation times and antibody dilutions.

Kontroll-lokus och beteende i grupp: en studie om sambandet mellan kontroll-lokus och individers beteende i en arbetsgrupp

The purpose of this study was to investigate the relationship between locus of control and behavior in a work group. The investigation was performed using two methods, self-report and observation, which were used in order to provide a description of how the individuals experienced their own behavior in a group context as well as of how they actually could be observed to behave. The 31 participants were divided into five groups. During the procedure each group received a task, which was to be discussed and solved by the group members together. Observations were carried out using IPA.

Hur har utvecklingen av andelen pension?rer i befolkningen p?verkat Tysklands arbetskrafts storlek fr?n 2000 till 2022?

Germany has experienced low birth rates ever since the 1970s when they fell below the replacement levels of 2,1 children per woman. Since then, their birth rate has been around 1,5 children per woman, which has caused an overall aging population. The consequences of the declining birth rates is that the previous generations are becoming larger than the younger generations. This demographic shift raises concern about how its potential implications might affect different aspects of the country and its economy overall. The aim of this paper is to try to discern the dynamic between the share of the labor force in relation to total population, with the share of pensioners in relation to the total population.

Felisolering av hytt- och chassikomponenter på tunga fordon

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.

Natura 2000-områden: rättsverkningar i jämförelse med vanliga naturreservat

Syftet med uppsatsen, att utreda de skillnader i rättsverkningar som finns mellan Natura 2000-områden och vanliga naturreservat,har jag uppnått genom att använda mig av traditionell juridisk metod. Genom att jämföra lagtextformuleringar, förarbeten och bakgrund till bestämmelserna om de två områdesskydden har jag funnit att reglerna om Natura 2000-områden har en betydligt större räckvidd än bestämmelserna för vanliga naturreservat. Allehanda verksamheter och åtgärder omfattas av den särskilda tillståndprövning som gäller för ingrepp i Natura 2000-områden, medan vanliga naturreservat har begränsad räckvidd till de ingrepp som stadgas i reservatsföreskrifterna. Jag har även funnit skillnader när det gäller inrättandet och upphävandet av områdesskydd, och resultatet är att EU-kommissionen utövar en stark kontroll vad gäller Natura 2000-områden. Kommissionen kan tvinga medlemsstaterna att inrätta särskilt skyddat område, och om medlemsstaten vill upphäva skyddet måste samråd ske med kommissionen.

Outsourcing av urval och inköp : En studie av hur bibliotekariens kompetens och yrkesroll påverkas av Bibliotekstjänsts profiltjänster

Traditionally, the majority of Swedish public libraries have carried out most of their acquisitions through Bibliotekstjänst's binding booklets. In recent years, however, many libraries have complemented the binding booklets and other services from Bibliotekstjänst by other ways of acquiring books, such as Internet bookshops, while other libraries have stopped using the binding booklets altogether. There are various reasons for this development, such as Information Technology making it possible for librarians to compare prizes and services from different retailers. Another important reason is the need for public libraries to meet new needs from their patrons, while remaining on a restrained budget, which often causes a need for reorganization of staff and resources.As a way of meeting the new needs for libraries, Bibliotekstjänst has created Profile Services (profiltjänster), a service in which a library outsources its acquisitions to Bibliotekstjänst. The staff of the library, in dialogue with Bibliotekstjänst, design a profile for the acquisitions for the library in question, in order to determinate which types and genres of literature the library and its patrons are requesting.

Avel och fruktsamhet hos nordsvenska hästen : en enkätundersökning

The fertility of the North Swedish horse was investigated using a questionnaire. Data concerning altogether 73 North Swedish stallions and 213 mares used for breeding during the season 2005 were collected and analysed. The survey also included the analyses of 305 breeding case books, especially distributed for this study, from 27 stallions. The aim was to collect information on how the breeding was carried out in the North Swedish horse, and to learn what categories of mares that were covered and what routines were used in these farms. Breeding statistics from 1999 to 2004 was also analysed to complete the questionnaire.

ISO 14001 : Från ledningsbeslut till certifiering

Tidigare ombesörjde organisationen karriär och karriärutveckling för den anställde och karriärkontraktet byggde på livslånga anställningar. Det nya karriärkontraktet bygger istället på en så kallad proteisk karriär (Hall, 1996), vilket utmärks av att individen ser sig själv som ansvarig för och drivande av sin karriär, att egna värderingar får styra samt att psykologisk utveckling är främsta mål. Studiens frågeställning var att undersöka om personlighetsfaktorer i termer av self-efficacy, självkänsla, locus of control samt neuroticism kan predicera proteiska karriärattityder. I studien användes kvantitativ metod och en enkätundersökning genomfördes på studenter. Korrelationsberäkningar visade att samliga personlighetsfaktorer samt proteiska karriärattityder var korrelerade.
