Do ambulance personnel think that mechanical compressions increase survival? Are there concerns that the device could damage the patient?Design: A cross-sectional study, quantitative approach with qualitative elements was conducted.Methods:Questionnaire form, which was answered by 44 ambulance personnel in an ambulance organisation in Sweden. Participants were on a scale of 1-5 to select how they agree with the claims of the study form and also submit their own comments.

Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

Pig behaviour during crowding : a study in organic and conventional herds

Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs? behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done.

Hur påverkas stammande personers talflyt av förstärkt hörselåterkoppling?

I denna studie undersöktes effekten av förstärkt hörselåterkoppling (enhanced auditoryfeedback, EAF) på observerbar stamning och upplevd känsla av talflyt hos vuxna personer som stammar. Så vitt vi vet finns inga tidigare studier av effekten av förstärkt hörselåterkoppling vid stamning. Mycket forskning finns dock på andra typer av hörselåterkoppling, som exempelvis frekvensförändrad hörselåterkoppling (frequencyaltered feedback, FAF), där man sett positiv effekt på talflytet hos personer som stammar. Deltagargruppen bestod av 14 personer i åldrarna 20-43 år, som stammade. Deltagarna fick läsa högt under olika förhållanden av hörselåterkoppling, de olika förhållandena som testades var förstärkt hörselåterkoppling och FAF mot normal hörselåterkoppling.

Antibiotikaresistens hos bakterier isolerade från friska hundar i Sverige : indikatorbakterier E. coli & Enterococcus spp samt Staphylococcus spp isolerade från hud

Objective: To determine the frequency of antimicrobial resistance in bacteria from healthy Swedish dogs and whether they are carriers of methicillinresistant Staphylococcus aureus (MRSA). Material: Samples from skin from the perineal region and from faeces collected in the anus with cottonswab (Copan) from 299 healthy Swedish dogs. Samples were collected at dog exhibitions. Method: Specimens were submitted for bacterial culture where bacteria (Escherichia coli, enterococci and staphylococci) were isolated and identified by current methods. Antimicrobial susceptibility testing was performed with a microdilution method where MIC-values were determined. Staphylococci with high degree of resistance were tested for presence of mecA-gene by PCR.

Cellphone Survey System : En studie om marknadsförhållanden och produktlansering för Tradewell Group AB

Today?s market for companies doing statistical surveys is a market consisting of mostly standardized methods where differentiating your company from the competitors is hard. Simultaneously both the society at large and technology in specific is under constant development and everything needs to be done at a faster pace with better precision. One of the companies on the market mentioned above is Tradewell Group AB. During 2008/2009 Tradewell has developed a new method for doing statistical surveys. The method named by Tradewell is called Cellphone Survey System, CSS and include using existing technology in a, for this market, unknown way.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Konstruktion av current conveyors via makromodellering

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Arbetstidsförlagd och subventionerad träning/motion och effekter på sjukskrivning

During the last Century a tremendously technical advancement has taken place and brought a change in society, which has affected workplaces in a monumental way. Many heavily and moveable physical working tasks at the work placement have been replaced with much easier and sedentary tasks.Two of the major reasons for sick absence in Sweden are illness in the locomotive organs and pain, which can be treated and prevented with physical activity on a large scale. Many employers offer their employees? subsidized exercise cards, which can be used during their free time. A health care exercise hour is one benefit that employers can offer their employees and normally takes place once a week during fully paid working time.

Byggnadens andra skepnad : En anpassning för att möta samhällets behov och krav

Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.

Utvärdering av felmeddelande i eMM Software Version 00-06 till SysmexXE-5000

Sysmex XE-5000 är en automatiserad cellräknare som utför mätningar enligt olika mätprinciper, de två som tillämpats i projektet är RF/DC(Radio Frequency/Direct Current) samt Flödescytometri med halvledarlaser. RF/DC bygger på förändringar i radiofrekventa resistansen och likspänningsresistansen. Förändringar i den radiofrekventa resistansen (RF) ger information om densiteten i cellernas inre (exempelvis kärnans storlek) och förändringar i likspänningsresistensen (DC) ger information om blodcellernas storlek. Flödescytometri definierar ett mått på cellers fysiologiska och kemiska egenskaper. Detektion av cellerna sker genom att de bestrålas med en laserstråle samtidigt som de passerar en och en i instrumentet. Informationen som fås ut från flödescytometri inkluderar spritt ljus och fluorescens.

"Det är viktigare att man trivs ihop, än att man gör de rätta övningarna" : Tränarens syn på relationen till idrottaren

Syfte och frågeställningarSyftet med den här studien var att ta reda på hur lagidrottstränare (representeras av fotboll) respektive tränare inom individuell idrott (representeras av friidrott) ser på sin relation till idrottaren. Frågeställningar: Hur uppfattar tränaren närheten mellan sig och idrottaren? Hur uppfattar tränaren samspelet mellan sig och idrottaren? Hur uppfattar tränaren långsiktigheten mellan sig och idrottaren? Hur uppfattar tränaren förståelsen mellan sig och idrottaren?Metod Insamlingsmetoden i denna studie var att utföra kvalitativa djupintervjuer med sex manliga tränare på elitnivå i två olika idrotter, fotboll och friidrott. Tränarnas ålder var 43 till 56 år, med ett genomsnitt på 50,5 år. Intervjuerna baserades på en vetenskaplig utgångspunkt och genomfördes först i form av två pilotintervjuer och därefter med tränarna i deras hemmiljö.  ResultatCloseness - Fotbollstränarna antydde att man bör ha en viss distans i sin relation till idrottaren medan friidrottstränarna hade en större önskan att komma idrottaren nära. Complementarity ? Att kommunicera genom att lyssna och ställa frågor är viktigt i relationen.

Elkvalitéproblem vid varvtalsstyrd motordrift i industrimiljö

Övertoner orsakade av varvtalsstyrda motordrifter ger problem i industrisystem. Syftet med studien är att identifiera problemen och ge rekommendationer för att undvika dem. Studien utfördes som examensjobb på KTH för konsultföretaget Ramböll. En litteraturstudie i ämnet kombinerades med elkvalitémätningar på drifter hos Sandvik Mining.Elkvalitéproblem orsakade av varvtalsstyrda motordrifter kommer till stor del av att frekvensstyrningen ger olinjärt strömuttag som, om nätet inte är tillräckligt starkt, påverkar spänningskvalitén. Problemen kan vara driftstopp, störd utrustning och ökat slitage på utrustning för att nämna några.Denna studie visar att vid ändringar i system innehållande övertoner kan framtida övertonshalter approximeras för vissa fall.

Testikelstörningar hos hingstar i Sverige

This project was initiated by a veterinarian, that at stallion performance tests for breeding during a number of years, noted breed differences in various types of testicular disorders. Therefore it was of interests to examine the proportion of testicular disorders within certain breeds. The aim with the project was in a first part to study cryptorchidism in common horse breeds in Sweden. Information about castrations of stallions performed during a 10 year period (2000-2009) was collected from computerized case records at five animal hospitals. The case records showed the numbers of castrations, normal cases and cases preformed on stallions with cryptorchidism, abdominal respectively inguinal.
