Utvärdering av inomhuslokalisering med Bluetooth Low Energy
Wireless communication is becoming more common, a relatively new technology within the area is Bluetooth Low Energy. It?s been developed to be energy efficient and in regard to compatibility. Alongside the growth of wireless technology, scientists and companies are looking for new areas of use. One of these is localization, which means to determine the position of a moving device with the use of stationary devices, an example of this would be GPS.This report means to evaluate indoor localization using Bluetooth Low Energy and was made for Combitech AB in Jönköping.
The rabbit as an animal model in dental implant research : with special reference to bone augmenting materials
Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.
Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten
In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.
Metoder för lastprioritering i fjärrvärmecentraler
A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
Vårtor på mjölkkornas spenar :
The reason why I choose the subject ?Warts on teats of Dairy Cows? was because the
herd I work with has big problems with skin-complaint on teats and udder.
So I found it interesting to try to find the reason why the cows look like they do and
even to find a way to relieve the trouble.
The examine work included both a literature research, an Experimental test,
concerning a comparison of different teat sprays and also an inquiry-research about
the occurrence of warts in practical herds in order to collect as much facts as possible.
Three companies, selling different types of teat disinfectants, were willing to sponsor
the teat dipping experiment. The aim of the experiment was to see if any special
disinfectant had more pronounced healing effects on teat warts. The date for the
experiment was 18th December 2004 to 22nd January 2005, which was going to be 5
weeks.The experiment was carried out in the herd of Ola and Eskil Carlsson in
Fjärlöv, Hässleholm.
The three compared teat spray chemicals were; Nova Viri Sun, Nardosept, and
BlockadeTM. These chemicals were compared to one control group, which teats were
treated with the ordinary chemical normally used in the herd, i.e.
Argumentation i skolan - för att klara de nationella proven i svenska i årskurs fem
Uppsatsens syfte är att undersöka vad barn i en skola i ett mångkulturellt samhälle behöver för att de ska klara av att argumentera.
För att komma fram till mitt resultat har jag använt mig av observationer och kvalitativa intervjuer. Jag har även genomfört en pilotstudie där jag har haft tillgång till provtexten som låg till grund för den argumenterande övningen vid det nationella provet i svenska våren 2009 samt elevernas texter. Undersökningsgruppen har bestått av tre pedagoger och 7 elever som alla har deltagit vid de nationella proven i svenska våren 2009.
De teoretiker som jag har ansett vara relevanta för detta arbete är Lev Vygotskij och Célestin Freinet.
Utvärdering av Sensus amningsutbildning för blivande föräldrar
ABSTRACTStatistics show that breastfeeding prevalence for Sweden has fallen since the mid 90´s. Studies show that breastfeeding offers health benefits to both mother and child and that the mothers' belief and confidence in their ability to breastfeed is a key factor to having a positive breastfeeding outcome. In 2010, Amningshjälpen in collaboration with Sensus studieförbund, started a nursing course, for mothers-to-be, who wished to breastfeed their babies and its aim was to prepare them for a successful and enjoyable experience.Objective: To examine whether a preparatory breastfeeding course can affect mothers' confidence in their ability to breastfeed and if that ability can affect the breastfeeding outcome when the child reaches four months. A further aim is to investigate the experience of perceived problems surrounding breastfeeding and what affect these might have on the mothers' confidence in breastfeeding when the child reaches four months.Design/Methods: A quantitative approach with prospective Experimental design was used to evaluate the study. The questionnaire Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) was used three times to measure women's trust in lactation.
Physiological (heart rate and cortisol concentration in saliva) and behavioural responses in horses to four reactivity tests compared to the trainer's opinion about the horses? temperament
When performing studies that test the reactions of horses in different situations, important information
may be available about the horse?s reactivity level. With information from these tests, accidents and
dangerous situations may be prevented. When the behaviours from tests are compared with race performance it may be possible to evaluate if some behaviours are more desirable at the race track than others. The aim of this study was to see if behavioural responses correlated with physiological
parameters (heart rate, cortisol), the trainer?s opinions and actual race performance.
Bogsår hos digivande suggor: inverkan av strategisk halmning och hull
The objectives of this Experimental study were to investigate if a strategic method to supply loose housed sows with large quantities of straw 2 days before expected farrowing and if the sow?s body condition had any effect on the occurrence of shoulder lesions 5 weeks after farrowing. Data came from a study conducted on four commercial piglet-producing farms in southwest Sweden between March and December 2009. At each farm one batch of sows was followed during two consecutive lactations. The sows were randomly assigned to two different treatment groups and the sows that remained in the batch during the second lactation switched treatment group.
Statistisk eller preferensbaserad diskriminering? : En studie om diskriminering baserad på kön och etnicitet i förhållande till socialt kapital
Diskriminering leder till en samhällsekonomisk ineffektivitet och tar sig uttryck både på individ- och samhällsnivå. Tidigare forskning har kartlagt och påvisat förekomst av etnisk diskriminering och könsdiskriminering på flera marknader i Sverige, men det har inte kunnat klargöras om diskrimineringen är statistisk eller preferensbaserad. Med kunskap om diskrimineringens karaktär kan beslutsfattare skapa effektivare policyinstrument för att motverka den diskriminering som visats förekomma i det svenska samhället. Ett problem på forskningsområdet är att det saknas empiriska metoder för att kunna särskilja diskrimineringen mellan olika förklaringsmodeller.Syftet med studien är att genomföra ett vinjettexperiment för att kunna särskilja den statistiska och preferensbaserade diskrimineringsteorin för diskrimineringsgrunderna kön och etnicitet. Studien syftar till att undersöka diskrimineringen i en svensk kontext i sammanhang som involverar tillit och generositet.
The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows
Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.
Kemin bakom framtidens avgasrening : En studie av ureasönderfall under kvävgasatmosfär
The purpose of this work was to provide a better understanding of urea?s decomposition and byproduct formation in an SCR system on heavy trucks. In my Experimental setup with TGA-DSC-FTIR (a combination of two thermal analysis methods and a method for gas phase detection), an FTIR method for urea in the gas phase was developed for the qualitative and quantitative determination of urea and its decomposition products. Chemicals such as urea, biuret, cyanuric acid and melamine of p.a. quality were used in this method development. Beforehand, there was no FTIR method available to detect these substances; hence, the aim of this work was to develop an FTIR method to understand the degradation chain of urea. The combination of TGA and DSC was used for analysis of different samples, where urea, biuret, cyanuric acid and melamine in varying amounts have been weighted in for various experiments in order to study the temperature at which a phase transition or reaction occurs, i.e.
Motorisk inlärning vid dysfunktionell postural hållning vid långvariga nackbesvär
Nackbesvär är ett samhällsproblem både gällande välmående och indirekt en kostnad för samhället. Gällande ett års incidens av nackrelaterade besvär har Skandinavien högre medelvärden än övriga länder i Europa och fler kvinnor än män drabbas. Vid screening av nackbesvär med en multidimensionell inriktning baserad på en biopsykosocial modell finner man grupper med bristande motorisk kontroll. En av dessa grupper har felaktigt motoriska kontroll mönster exempelvis på ett sådant är en framåtskjuten huvudhållning. Syftet med studien var att undersöka effekterna av motorisk inlärning vid dysfunktionell postural hållning hos personer med långvariga nackbesvär.
Kentucky Inventory of Mindfulness Skills: validering av den svenska översättningen och en studie av anhöriga till borderlinepatienter.
This paper has two parts. In the first part we analyse the Swedish translation of KIMS and we compare it with the American version that Baer and colleagues developed(Baer et al, 2004). Our focus is the factor structure, internal consistency, scale correlations and validity in relation to the already validated translation of the MAAS. The second part has three issues: Does a group of relatives to persons with borderline personality disorder differ from a group of university employees with respect to different aspects of mindfulness? What are the correlations between KIMS and the symptom measure BSI-GSI for the group of relatives? Has the Family Connections program had any effect on the degree of mindfulness for the group of relatives? 123 university employees answered the KIMS questionnaire.
