Design, konstruktion och test av LED-spektrometer

A LED spectrometer has been constructed for qualitative spectrometry using certain wavelenghts. The LEDs and the photodiode are being controlled with a microcontroller that is connected to a computer to power the components and save data. The spectroanalysis made with the LED spectrometer were significantly different to a standard spectrometer, concluding that more analysis should be made until a final product is ready. Some areas of improvements are suggested. .

Lane Keeping Aid : ett förarstödjande system för bilar

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

Sjuksköterskors och patienters upplevelse av fysisk beröring i omvårdnaden : en litteraturöversikt

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

Följdinvandring och medborgarskap : en statistisk analys

During the last years around 100 000 immigrants have arrived to Sweden, people with different reasons and different goals for settling down in Sweden. The reason for immigrating to Sweden that will be dealt with in this thesis is following immigration, i.e. when someone moves here because they have relatives living in the country.The reason why it is interesting to study following immigration is that it is an affecting factor for how many that will immigrate to Sweden the following years and may then be used to make a forecast, based on how many first time immigrants there are. To be able to investigate the following immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future.The other part of this thesis will inquire the matter how inclined immigrants are to become Swedish citizens, whether they even apply for citizenship and also how long time it takes from the time when they fulfil the conditions for Swedish citizenship until they apply.

Nyckeltal i ideella föreningar : ? en studie kring ishockeyföreningar

The purpose of this paper was, on the basis of the association?s annual reports, to describe appropriate key performance indicators for non-profit associations. The purpose was furthermore to study how the associations show their goal-attainment. The research was delimited to contain the second category of non profit associations, which include sports associations. The authors choose three non profit associations, which according to the law, shall draw up annual reports. The three ice hockey associations HV71, MODO Hockey and Frölunda Hockey Club, were thereafter chosen on the basis of those delimits.

Postoperativ smärta och illamående vid behandling med Dolcontin/Depolan/Morfin och Oxycontin/Oxynorm : En jämförande studie

Syfte: Syftet med denna studie var att jämföra graden av smärta och illamående hos två patientgrupper inom ortopedi som smärtlindrades med tablett Dolcontin/Depolan/Morfin eller tablett Oxycontin/Oxynorm postoperativt dag 0, 1 och 2. Syftet var även att undersöka vilka riskfaktorer enligt Apfel Risk Score som kan påverka grad av illamående samt att undersöka om en korrelation fanns mellan preoperativ information och incidensen av postoperativt illamående och kräkning (PONV).Metod: En komparativ studie med kvantitativ ansats. Data samlades in genom två olika enkäter, varav en enkät fylldes i av patienterna och en enkät av sjuksköterskorna. 48 patienter inkluderades i studien, 24 per substans. Både kvinnor och män som genomgått elektiva knä- eller höftarteroplastikoperationer deltog i studien och de var mellan 31-77 år.

Hälsoutbildningens påverkan på psykologiska resurser hos chefer och anställda

This study is a quantitative study designed to examine whether training in health issues may have contributed to the increase in head managers' psychological capital (PsyCap). Construction consists of the following components: self confidence, hope, optimism and resilience. A high PsyCap considered beneficial in organizational change and steer towards the positive development and helps individuals in stressful situations. The results show an increase of characteristics such as hope and optimism among managers (N = 15) who have undergone training in health issues compared with managers who have not undergone training. However, the tests show no significant difference in head managers' attitudes to health breaks, not the severity of granting health breaks in the groups as a result of training.

Fungiciders påverkan på kvävehalten i höstvete : hur påverkar användandet av fungicider utnyttjandet och inlagringen av kväve i höstvete?

A common perception is that fungicide treatments increases yield, but that the nitrogen of the particular grain is diluted so that the overall removal of grain nitrogen from the field remains unchanged. The aim of this paper is to demonstrate that a healthy crop reduces the risk of nutrient loss from agricultural land. The results from genotype and plant protection trials often show constant nitrogen content in the grain, although the yield has been increased. Results from such experiments are therefore processed in order to confirm this and show that it is no statistically significant difference between the protein content (and also nitrogen content) in crops which have undergone fungicide treatment compared to crops which remained untreated. The trials processed have been carried out in the southernmost part of Sweden and are distinguished to concern winter wheat production.The explanation to the results is that a healthy crop is able to maintain the biological functions of the plant in a more efficient way than a crop damaged by a fungal infection.

Databaser i molnet : En prestanda utvärdering

AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.

Löneutvecklingens bestämningsfaktorer i Sverige

The purpose of this essay is to acquire variables that explain and may be used as a base for wage estimation in the private sector in Sweden. The factors that are assumed to have an impact on wage estimation are based on earlier Swedish and international studies. Business survey data, which is based upon monthly questions to firms in various sectors of the Swedish economy posed by the Swedish National Institute of Economic Research, will be analyzed to find out weather they have an impact on Swedish wage settings or not. Tests including business survey data are yet rarely frequent, why this essay will be some kind of a pioneer within the area. To estimate significant factors that influence wage setting in Sweden, three different wage equations have been modeled and tested with a regression model.

Skadeprevention genom kognitiv beteendeträning för unga fotbollsspelare med hjälp av biofeedback.

Det positiva sambandet mellan stress och idrottsskador är väl dokumenterat i litteraturen. Ett ökat antal psykologiska skadeförebyggande interventioner visar att det är möjligt att förebygga idrottsskador genom kognitiv beteendeträning. Användandet av biofeedback tillsammans med kognitiv beteendeträning i skadeförebyggande syfte är dock en relativt outforskad interventionsstrategi (Johnson, 2007). Syftet med studien var att undersöka om det genom interventionsbaserad kognitiv beteendeträning i kombination med biofeedbackanvändning gick att minska antalet idrottsskador för fotbollsspelare. Deltagare ifrån fyra idrottsgymnasier (16-19 år) delades in i en experimentgrupp (n=13) och en kontrollgrupp (n=14).

Ägarstrukturens påverkan på tillämpningen av Svensk kod för bolagsstyrning: En studie av bolagsstyrningsrapporter

In the light of some company scandals the Swedish Code of Corporate Governance, the Code, was introduced in the year of 2004 to reinforce confidence in how Swedish listed companies are managed. As many of the other European codes of corporate governance, the Swedish Code is based on the principle of ?comply or explain?. The need for corporate governance regulation arises from the inherent conflict of interest between owners and managers. This conflict is limited in companies controlled by a family in contrast to companies that lack a strong owner.

Effekten av värmebehandlat silan på bindningsstyrkan mellan en litiumdisilikatbaserad glaskeram och ett adhesivt cement

Vid adhesiv cementering, så kallad bonding, rekommenderar fabrikanter att glaskeramers cementeringsyta etsas innan applicering av silan. Att värmebehandla silan med respektive utan etsning, har i tidigare studier visat en höjning av bindningsstyrkan mellan olika material. Den litiumdisilikatbaserade glaskeramen IPS e.max® Press har funnits på marknaden sedan 2005 och få studier har gjorts på ytbehandlingar och dess effekter på materialet och bindningen till olika material. Syftet: att undersöka om ytbehandling med värmebehandlat silan ger en högre bindningsstyrka till adhesivt cement hos en litiumdisilikatbaserad glaskeram, jämfört med kombinationen etsning och silanisering. Material och metod: 12 litiumdisilikatbaserade keramiska block pressades. Blocken delades parvis in i sex grupper och ytbehandlades med etsmedel och/eller silan med eventuell påföljande värmebehandling. Blocken cementerades samman varpå mikrostavar sektionerades fram, som sedan termocyklades. 10 provkroppar ur varje grupp valdes ut för ett microtensile bond strength test. Frakturytorna bedömdes i mikroskop.
