Utvärdering av BD Vacutainer® Rapid Serum Tube vid analys av S-Paracetamol och S-Etanol

Avdelningen för klinisk kemi vid Länssjukhuset i Kalmar analyserar läkemedel och alkoholer med BD Vacutainer® Plus Plastic Serum Tube (Serum Tube), som kräver en koagulationstid i upp till 60 minuter. BD Vacutainer® Rapid Serum Tube (RST?) innehåller trombin och kräver en koagulationstid på endast 5 minuter. Syftet med studien var att undersöka möjligheten att förkorta den preanalytiska väntetiden före centrifugering vid intoxikationsanalyser i serumrör från akutmottagningen. Studien utfördes genom att jämföra RST? med Serum Tube vid analys av S-Paracetamol och S-Etanol.

Bors E23 - Framtagning av eldriven röravklippningsmaskin

Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..

Påverkas röstkällans egenskaper av förändrad stående kroppshållning? En experimentell studie av otränade mansröster

The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.

The aim was to identify if the veterinary nurse is as competent as the veterinaian in placing a nasoesophageal feeding tube. The aim was also to identify the complications with malnutrition and the advantage and disadvantage of the procedure. This essay is based on several interviews with both veterinary nurses and veterinaries. 16 persons were asked 4 short questions in conjunction with an intensive care/emergency and surgery congress in Gothenburg in February 2013. In addition 4 major hospitals that provided intensive care were asked to answer 5 more detailed questions, one answer from a veterinary and one answer from a veterinary nurse was requested.

Studie av nötnings- och friktionsegenskaper vid höga temperaturer i Kanthal APMT

During this master thesis, wear and friction properties for the high-temperature alloy Kanthal APMT were studied. The results were also compared to 253MA. The initial tests showed, among other things, that the surface fineness of the muffle tubes matters in real applications like conveyor belts. A 253MA-sample wear-tested against a 253MA-tube showed lowest wear at 900°C while a pre-oxidized APMT-sample wear-tested against a APMT-tube had the lowest mean value of the friction force at 1100°C, compared to all other tests..

Nutrition hos patienter med Subarachnoidalblödning

ABSTRACTIn an intermediate section at a large university hospital are patients with subarachnoid hemorrhage (SAH) cared for. There are international, national and local guidelines how nutrition therapy should be implemented and how much energy each patient should be given when hospitalized. The purpose of this study was to examine the documentation and actions on nutrition in patients with SAH and to see if guidelines on nutrition were followed. The study was a quantitative, retrospective record review that was analyzed statistically and descriptive. 26 patients were included.

Rörfonation eller traditionell svensk röstbehandling? : En jämförande studie mellan två olika metoder för röstbehandling

Rörfonation och traditionell svensk röstbehandling är två av de vanligaste behandlingsalternativen inom svensk röstlogopedi idag. Som forskare är det viktigt att kontinuerligt utvärdera de behandlingar som erbjuds för att göra vården mer kvalitativ och kostnadseffektiv. Finns det skillnader i behandlingseffekt mellan dessa två röstbehandlingar? Är skillnaderna så tydliga att det går att fastslå att den ena behandlingen är att föredra framför den andra?Med analyser av ett patientmaterial, före och efter behandling, i form av akustisk analys, perceptuella bedömningar av en grupp erfarna logopeder samt patienternas självskattningar syftar föreliggande uppsats till att besvara vad behandlingsformerna har för effekt inom dessa områden.Patientmaterialet bestod av totalt 28 patienter varav 23 fullföljde behandling. Tolv av dessa erhöll behandling med rörfonation medan resterande elva patienter erhöll traditionell svensk röstbehandling..

Larynxmask eller endotrachealtub prehospitalt ? styrkor och svagheter : Litteraturstudie

ABSTRACTBackgroundWhen faced with an unexpected cardiac arrest the ambulance nurse is in responsible for taking advanced actions to create a clear airway. Two accepted methods for this is endotracheal intubation and application of laryngeal mask.AimThe purpose of this study was to examine the use of endotracheal intubation compared to application of the laryngeal mask in unexpected cardiac arrest.MethodLiterature study with quantitative approach. A systematic search of 21 articles comparing the laryngeal mask with the endotracheal intubation has been made using Pub-Med and CINAHL. A quality review according to Forsberg and Wengström has been made.ResultsLaryngeal mask had a higher rate of successful applications compared with endotracheal intubation. Time for applying the laryngeal mask was shorter in seven out of ten of the studied articles.

Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Stockholms Lokaltrafik, SL : kundinvolvering i trygghetspolicyn

Society has seen a tremendous increase in threats, violence and especially unprovoked violence perpetrated by youths. Violence and more seriously unprovoked violence has become a major problem for many service corporations as it gives them bad image and reputation. Corporate Social Responsibility CSR encourages many companies to engage in social activities as they realize that the company is part of the society and the environment. What affects society may sooner or later affect the corporate. For any business to prosper and create a long-term relationship with its customers, it needs a safe environment both for the customers and staff.Feedback from customers and staff is survival and these two (customer and staff) are the most vital assets any firm could have.

Zinklegering i åldrat och kylt tillstånd : Identifiering av parametrar som förändrar materialegenskaperna i Zamak5

Bilsäkerhet är en viktig fråga i dagens samhälle. Det enklaste sättet att skydda sig vid en bilfärd är genom att använda säkerhetsbälte. En säkerhetsbältesrulle är uppbyggd av flera olika komponenter, en av dessa kallas torque tube som tar energi när kroppen fångas upp av bältet vid en eventuell kollison. Säkerhetsbältet ska skydda passagerarna i bilen i många år och vid olika temperaturer. Torque tuben är i detta fall gjuten i en zinklegering som heter Zamak5 som förändrar sina materialegenskaper i åldrat och kylt tillstånd.

Går det att analysera S-TSH, S-T3 fritt och S-T4 fritt på BD Vacutainer® RST??

Sköldkörteln (tyroidea) är ett endokrint organ som påverkar ämnesomsättningen. Tyreoidea stimulerande hormon (TSH) frisätts från hypofysen och stimulerar syntes och frisättning av tyreoideahormonerna trijodtyronin (T3) och tyroxin (T4). Tyreoidea hormonerna har i sin tur en negativ påverkan på frisättningen av TSH. TSH, T3 fritt och T4 fritt analyseras på serum med immunokemiska metoder. Becton Dickinson (BD) har tagit fram ett snabbkoagulerande provrör för analys av serum.
