This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.

The activities of beavers in forested landscapes affect both ecological and economical values. The creation of the dynamic wetland mosaic associated to beaver activities can even improve the quality of water and have been documented as an important landscape engineer affecting the environment for many species. The local office of Sveaskog in Skinnskatteberg is responsible for the management of large areas of the forests in the County of Västmanland. In this area one of several company?s goals are to create ten new wetlands in their own forests as a part of cooperation with the Swedish bird society and Swedish wetland association.

Detta arbete behandlar en specifik typ av överbelastningsattack som blir allt mer populär. Dessa attacker utförs genom öppna reläer med syftet att få ut en avsevärt mycket högre effekt än den som annars är uppnåbar. Granskning av attacker utförda genom tjänsterna DNS och NTP har utförts med syftet att ge en klar bild av hur allvarligt hotet är och även klargöra hur en systemadministratör kan säkra tjänsterna för att skydda både sina egna och andras resurser. Resultaten av undersökningar visar att en attack utförd genom en DNS-tjänst ger under optimala förhållanden en amplifikationsfaktor av "102.4" och en attack genom en NTP-tjänst ger under optimala förhållanden en amplifikationsfaktor av "229.16". Resultaten visar även att problemet kan lösas helt eller delvis genom att begränsa tillåtna nätverk eller stänga av rekursion i DNS och kommandon i NTP..

Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The contractsused are electricity forwards traded at the Nordic electricity market Nord Pool. Animbalance between buyers and sellers can lead to a situation where the forward price notequals the expected spot price. The difference between the forward price and the expectedspot price is referred to as the market risk premium.

Denna uppsats undersöker hur intressenter och aktörer påverkar, eller kan påverka en destinationsutveckling. För att specificera det något har författarna gjort en fallstudie av en påtänkt destination som är under utveckling lokaliserad i Figeholm, Kalmar län. Då destinationer överlag kan ha en vidare påverkan på regioner, handlar denna uppsats om den regionala påverkan som The Circle Resort kan tänkas få och föra med sig genom sin utveckling. Meningen med detta arbete är att försöka visa på hur de olika intressenterna och aktörerna samarbetar och kommunicerar med sin omgivning. Materialet till empirin är insamlad från källor som har, eller kommer att ha, en roll i destinationens utveckling.

Abstract:In previous experiments with the bacterium Ideonella dechloratans a probable sequencecoding for a cytochrome c protein (cyt c) was observed, the sequence is assumed to have afunction in the bacterial respiratory chain. Detection attempts have been made to try to findthis protein, but have not succeeded. The purpose of this project is to detect the expressionof mRNA associated with the cytochrome c. And if it is detected, it will also be investigated ifthere is any difference in expression of the mRNA due to aerobic or anaerobic environment.Total RNA was purified from cultures grown under aerobic and anaerobic conditions. cDNAwas then synthesized using reverse transcriptase and subsequently amplified with thespecific primers in a qRT-PCR.qRT-PCR testing showed a distinct amplification of primer product, confirming that I.dechloratans expresses mRNA coding for the cyt c protein.

The purpose of this masters thesis is to examine how librarians work in a literary educational role with literary circles for adults and youth, in public libraries and at school. The study also examines whether participation in book discussion groups has any effect on participants and librarians regarding changes in reading habits and in personal development. Another aspect investigated was how participants experienced the atmosphere in the group. We have conducted qualitative interviews with five librarians who have lead different literary circles and with two participants from each literary circle. In all 13 interviews were conducted.

Nematode-transmitted plant viruses (such as nepoviruses) cause great economically losses in commercially important plants such as tomatoes, grapevines and raspberries all over the world. To avoid spread of the viruses the interest in mapping the viruses has increased. One of the important nepoviruses infecting European red raspberries (Rubus idaeus) is Tomato black ring virus (TBRV). TBRV has earlier been confirmed in raspberry samples from Belarus by ELISA and the aim of this bachelor degree project was to confirm these results by amplifying, cloning and sequencing the coat protein (CP) gene of the virus. In total eight viral cDNA samples, from two different raspberry samples, were amplified and sequenced.

Rotavirus and coronavirus are the two most common viral causes of neonatal calf diarrhea and their presence causes a lot of economic damage to the farmers as well as suffering to the animal. By getting better knowledge about the viruses we may help in tracing transmission and in producing new vaccines. This paper served to study the molecular epidemiology of rotavirus and coronavirus in fecal samples collected from two different farms in the state of São Paulo, Brazil. These samples have been studied with focus on the gene VP4, VP7, NSP4 in rotavirus and the gene S1 in coronavirus. From the first farm the screening PCR showed that 12/48 samples were positive for rotavirus and 4/48 positive for coronavirus.

Energi är en resurs som måste användas effektiv för att undvika onödig negativ miljöpåverkan och utgifter. Återmatning från nedåtgående malmtåg till uppåtgående malmtåg leder till en effektivisering i energiutnyttjande. Beräkningen av den återmatade energin utgår ifrån tågets lägesenergi och förlusterna från räls, lutning, vind och kurvor. Totalt kan återmatning av energi ge en besparing på 20 % för enkelspår och 20 % respektive 21 % för dubbelspår. Dubbelspår kan ha mer trafik än enkelspår men förhållandet mellan konsumerad och återmatad energi är i princip den samma.

Syfte: Syftet med studien är att analysera och beskriva hur ett företag kan arbeta med varumärkesutvidgning samt identifiera framgångsfaktorer, motgångar och bakomliggande orsaker som kan förekomma vid en varumärkesutvidgning.Metod: Vår studie utgår främst från den kvalitativa metoden. Inledningsvis presenteras ett ramverk för lämplig teori för att vidare kompletteras med intervjuer. Den empiriska delen består av kvalitativa intervjuer med företagen King Salming AB, Salming Sport, Peak Performance, Björn Borg och L`Homme Rouge. Slutsats: Vi har funnit stöd i, att teorin som avser varumärkesutvidgning kan användas i verkligheten. Samtliga bolag följer en varumärkesstrategi där kärnvärden och territorium utgör basen för en varumärkesutvidgning. I de fall där varumärkesutvidgningen inte fungerat som tänkt är det också avståndet till kärnvärdet och territoriet, som är ett av det återkommande problemet.

The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

In the current situation is the straight tube cutter, that provides Luvata?s line of large recoolers with copper tubes, manually operated. To prevent damages and facilitate mounting the tubes must be properly arranged when they leave the machine. This report aims to investigate and present an automated solution where the operator does not need to participate in the process. A number of theories have been drawn up and tests have been done.
