Påverkan av EMLA-behandling hos barn vid etablering av perifer venkateter ínför operation

SAMMANFATTNINGSyfte: Syftet med föreliggande pilotstudie var att studera rutinerna för preoperativ Emlabehandling på barn. Pilotstudien inriktar sig specifikt på att undersöka om tiden mellan borttagande av EMLA-behandling och venpunktionen påverkar antalet försök som krävs för att etablera perifer venkateter på barn inför operation.Metod: Patienterna kvasirandomiserades till två grupper. Totalt 73 barn deltog i studien. Åtta barn exkluderades då de inte utsattes för några försök för att etablera perifer venkateter. Således inkluderades 65 barn i pilotstudien.

Vetenskaplig kommunikation i förändring: en fallstudie av ett svenskt forskningsbiblioteks beståndsutveckling

For hundreds of years the scientific journals has been the foremost tool for scholarly communication. Publishing of research results is very important for scientists. Often the research is bound to the university and the research libraries supplies the scientist with all journals needed. The last decades the libraries have seen the costs for subscriptions to journals explode. Commercial publishers often lie behind the mostly unmotivated escalation in price.

Standardisering av funktionsblock for PLC

Automationscenter & Bråvalla Elteknik AB is a company that offers the market completed total solutions where the customer can operate and monitor their production from the terminal. In these total solutions they lack standard circuit which are developed by the company and which could manoeuvre/control/monitor controlled process objects. This report defines the work of developing the most common standard circuits.The report is initiated by a short theoretical part about PLC and the PLC system, with a connected terminal, which has been used. Thereafter, the turnout of the demands of specification is reported, after discussing with the supervisor in the course of the project. The report concludes with a disclosure of how the programming, the documentation and the testing have proceeded and a final discussion concerning the project and proposals on continuation.The result is a CD with the documentation of standard circuits and how they are implemented in a new project.

Bootstrapvalidering av konfidensintervall för ett standardiserat mått för att jämföra behandlingsbenägenhet mellan sjukhus

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Preoperativ patientutbildning - att ta tillvara patientens egna resurser genom att skapa känsla av sammanhang.

En patient som ska genomgå en operation kan uppleva känslor som maktlöshet och utsatthet. Patientenkan även känna sig rädd för själva ingreppet och narkosen och vara orolig för hur operationen kan kommaatt påverka livet. Det är enligt kompetensbeskrivningen för legitimerad sjuksköterska och hälso- ochsjukvårdslagen sjuksköterskans ansvar att ge patienten den information hon/han behöver för att kunnautöva självbestämmande och delaktighet i omvårdnaden. Enligt Antonovskys teori om salutogenes ochkänsla av sammanhang kan en människa, trots sjukdom, uppleva hälsa och känna tilltro inför framtiden.Syftet med föreliggande litteraturöversikt var att undersöka om sjuksköterskan genom patientutbildning isamband med operation kan möjliggöra att patienten får tillgång till och kan använda sig av sina egnaresurser och den egna förmågan för att främja hälsa och välbefinnande. För att finna svar på dettastuderades forskningsartiklar inom ämnet och efterhand framträdde övergripande och underliggandeteman.

Saphenusnervblockad ? En del av den multimodala smärtlindringen efter en främre korsbandsrekonstruktion med hamstringmetod

SAMMANFATTNINGPostoperativ smärta uppstår genom vävnadsskador i samband med operation. Numerisk Rankningsskala (NRS) är ett smärtskattningsinstrument. Postoperativ smärta behandlas oftast med analgetika, ibland ges även någon form av opioid, till exempel Fentanyl. En annan smärtlindringsmetod som används är nervblockader där lokalbedövningsmedel bedövar nerver. Smärtlindringen ska utgå ifrån patientens unika livsvärld.

Förbränningslära för bubblandefluidbädd

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Industriellt köpbeteende av utlandsresetjänster

The purpose of this thesis is to examine the organizational buying behaviour in the purchase of travels abroad. We have conducted a case study of two companies, one medium sized and one larger. Our empirical studies have shown that the companies? buying process is divided into two types, the process of recruit a new travel supplier and the process of a straight rebuy of a regular travel service. In the recruiting process we found that the evaluation process of the purchase is an ongoing process that contradicts estab-lished theories.

Ålandsfrågan : En studie ur ett medieperspektiv

AbstractThe purpose of this essay is to study in what way teachers in preschool work with pupils enabling them to gain influence and involvement in their learning.Influence means being able to make your voice heard which is an important component of a democratic society. Involvement is about being part of a community in which everyone is welcomed regardless of beliefs and opinions. Several of today's researchers believe that learning occurs in interaction between people. Teachers providing meaningful assignments to pupils, they become more motivated to learn.The study is based on observations of how teachers work with influence and involvement in controlled sessions, and interpretations of them. My results show that children become involved in their learning when they are confronted with a variety of pedagogical approaches to learning.

Precision och stabilitet vid klusilexplosionen hos patienter med Parkinsons sjukdom : En jämförelse mellan effekten av Deep Brain Stimulation i kaudala zona incerta (cZi) respektive nucleus subthalamicus (STN)

Bakgrund: Deep Brain Stimulation (DBS) i nucleus subthalamicus (STN) och i kaudala zona incerta (cZi) har visat positiva effekter på motoriska symtom (rörelseförmåga och balans) vid Parkinsons sjukdom. Efter DBS har dock negativa taleffekter noterats, inklusive nedsatt artikulatorisk precision och stabilitet. Nedsatt artikulatorisk precisionoch stabilitet påverkar klusilproduktionen mest vilket kan resultera i att klusilexplosionen uteblir eller att multipla explosioner uppstår.Mål: Att undersöka artikulatorisk precision och stabilitet vid klusilexplosionen efter DBS i STN respektive cZi.Metod: I studien deltog 19 patienter varav 9 deltagare stimulerats i STN och 10 deltagare i cZi. Talinspelningar gjordes innan operation och ett år efter operation med DBSstimulering på och av. Klusilerna i talmaterialet delades in i tre kategorier, de med en klusilexplosion, de med två eller flera klusilexplosioner samt de utan klusilexplosion.

Att navigera med gester : Gestbaserad teknik för framtiden

Technology evolves quickly, with innovative ideas growing everywhere. Still, no technology is anywhere near challenging the mouse and keyboard for navigation of your standard computer. This study focuses on comparing the traditional technologies of mouse and keyboard with the new technology of gestures - in this case Leap Motion - in purpose of finding how the usage differs and what the potential users want from the competing technology. The experiment was executed in a controlled environment, with as few external factors as possible. We found that although the test subjects found Leap Motion fun, the test subjects do not want to surf the web with gestures.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Munhålestatus hos arbetande hästar :

Seventy-two working horses (they had been ridden with bit and bridle within the last two weeks) were examined in the oral cavity. Findings and status were noted. The horses were randomly chosen among individuals without clinical symptoms from the mouth and gastrointestinal system. The result showed that 93% of the horses had changes in the mucus membranes, 86% in the form of ulcerations. The P2 region was most commonly affected followed by wounds more caudally in the mouth (P3-M3 region).
