Subjektiva och objektiva jämförelser mellan två benledningshållare, Softband och Adjoin

Background: Bone anchored hearing system is a surgically implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..

Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

Sjuksköterskans identifiering av smärta hos äldre personer med demenssjukdom : En litteraturstudie

Syfte: Att utifrån litteratur beskriva hur sjuksköterskor kan identifiera smärta hos äldre personer med demenssjukdom, samt att undersöka vilka mätinstrument som finns att tillgå för att beskriva smärta. Metod: Litteraturstudien var av deskriptiv design. Litteratursökningen gjordes i databaserna PubMed och Cinahl. Resultat: Resultatet baserades på 14 vetenskapliga artiklar som visar att det finns många uttryck för smärta som sjuksköterskan kan använda sig av för att identifiera smärta hos äldre personer med demenssjukdom. Resultatet visade att det är mycket svårare att identifiera smärta vid omvårdnad av äldre demenssjuka, då de inte kan kommunicera som kognitivt intakta personer.

Utvärdering av regnmätning och droppstorleksfördelning från en distrometer

Nederbördsmätning är viktigt inom många områden och en relativt ny teknik är enoptisk distrometer som med hjälp av laserteknik mäter nederbördspartiklarnasdroppstorlek och fallhastighet. Syftet med detta arbete var att undersöka hur välThies distrometer stämmer överens med nederbördsmätning från ett vippkärl ochmanuella mätningar från institutionen för geovetenskaper vid Uppsala universitet.Institutionen för geovetenskaper överväger att gå över till denna teknik och därmedbehövdes distrometern utvärderas för olika faktorer som kan påverka instrumentet.Vid jämförelse mellan instrumenten visade det sig att distrometern totalt sett samladein mer nederbörd än de andra mätarna. Det är svårt att avgöra vad skillnaden mellaninstrumenten kan bero på men felkällor så som avdunstning och vätning hos vippkärletoch manuella mätningar kan ge mindre nederbörd. En annan orsak kan varafelkalibrering av datan från distrometern. Inga samband hittades för vindhastighet,vindriktning och typ av nederbörd mellan de tre instrumenten.En vidare undersökning gjordes för droppstorleksfördelningen för att ge exempelpå fördelar med en distrometer.

This project is a contribution in the debate of sustainable city planning. The conceptual ideas in this project can be used on many places and are here applyed on the center of Nacka, outside of Stockholm. The essay is based on an entry in the competition Europan 9, advertised by Europan in collaboration with the municipality of Nacka. The theme of the competition is ?sustainable city and public space?. The discussion of the sustainable city is a very wide subject which needs to be narrowed to suite the context of Nacka.

Utvärdering och jämförelse av olika fälttester för fotbollsspelare

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Motiv och värdering vid köp av skogs- och lantbruksfastigheter i Västerbotten

The study has been done on behalf of and in cooperation with LRF Konsult. The purpose of the study was to try to find out how forest estate buyers valuated different parts of the estate at the time of the purchase and to see if it was possible to identify different trends between different kinds of purchasers. The study is delimited to Västerbotten County and all the purchases were made thru LRF Konsult. The background of the study is that the forest estate purchasers are paying more and more for the forest estates. The prices are often much higher than the net present value which means that they are paying for something more than just the timber value. The study is made with a questionnaire mailed to one hundred forest estate purchasers. Answers got returned from 48 of them.

Innehållsvaliditet och användbarhet - en initial prövning av bedömningsinstrumentet Assessment of Work Characteristics (AWC-1)

Insikten om vikten av att använda vetenskapligt beprövade bedömningsinstrument inom arbetsterapi ökar. Många instrument för bedömning av arbetsförmåga uppvisar en brist på vetenskapliga kvaliteter såsom validitet och reliabilitet. Detta medför ett behov av att vetenskapligt testa de instrument som idag används samt vid utvecklingen av nya instrument använda sig av systematisk vetenskaplig metodik. Syftet med denna studie var att utföra en initial prövning av innehållsvaliditet och användbarhet för bedömningsinstrumentet Assessment of Work Characteristics (AWC-1). Stipulativa definitioner av innehållsvaliditet och användbarhet användes för att avgränsa studien.

650 stycken citroner, 120 stycken påmerantzer, 200 stycken apellisiner : Vägledning till tullarkiven på Landsarkivet i Uppsala

The organized and controlled form of collecting consumption taxes and toll from the import and export trade goes back to the 17th century in Sweden. The customs administration and procedure were regulated by royal announcements, and the majority of the documents found in the customs archives represent thus records stipulated by such notifications. The customs archives can be used for research on several levels; the announcements reflect currents within both the domestic and foreign politics, while the account lists for financial statistics portray the extent of the trade. The various lists of compilation can be further used to follow for instance the development of different units of measurement, the expansion of tax rates, the value of trade goods or the changes in monetary units or systems. The diaries, architectural plans of the customs offices and maps of the toll areas place the customs officials and their work within the local scenery.The thesis focuses on archives deriving from customs located at harbors and on the Swedish-Norwegian border in the county of Dalarna.

EN JÄMFÖRELSESTUDIE AV PLAST- OCH GLASHEMOCYTOMETRAR FÖR BERÄKNING AV BLODCELLER I VENÖST OCH KAPILLÄRT HELBLOD

Hematology-instruments that analyze blood cells can at specific cases be followed by manual counting with a hemocytometer. The plastic hemocytometer which has a fixed coverslip and is assigned for disposable use, appears to reduce the problems arising from the use of the traditional glass hemocytometer, for instance coverslip-application difficulty and dust particles. Capillary whole blood sampling may be useful for patients at the emergency department and in addition, a smaller volume of blood is taken compared to venous blood sampling. This study will focus on the platelet- and leukocyte count (PLT and WBC) in venous and capillary blood, in order to compare the plastic- and glass hemocytometers with Sysmex XN-2000 (Sysmex Corporation, Kobe, Japan), and verify if capillary whole blood sampling can be used for the measurement of these hematological parameters. 30 subjects donated both capillary- and venous blood samples and these blood samples were analyzed with glass- and plastic hemocytometers with Sysmex XN-2000 as the reference method.

Personlig integritet mot Arbetsledningsrätt : Användandet av belastningsregistret i anställningsprocessen

Due to the wide usage of different databases administrated by the Swedish government to keep control over its citizen?s the issue has arisen concerning if this information is subject for other purposes then originally acknowledged. Executives induced in recruitment for labour has over the years extended their need for information accumulated by these systems. Especially data from the criminal records registry are now being used as a normal step in the employment process among a vastly growing spectrum of enterprises and businesses all over the country. This thesis aims to illuminate the subject by grasp to what extent the described behaviour can be considered legally accepted according to the law or if these actions are inflicting with the foundational juridical principles that has to be ensured by the Swedish government due to our constitutional law.A strict jurisprudential method has been applied throughout the entire thesis to ensure the reliability of the results. The diversity of sources has gently been put together to assure the overall quality.
