En jämförelse av stickprovsmetoder vid mätning av radioaktivetet på en yta
This study compares the sample variance of the mean in a simple random sample (SRS) and a systematic sample from a surface. The study also compares the prediction error variance in a SRS and systematic sample from a random field. Recommendations are presented on which method to use in the clearance and exemption process in the nuclear industry. The results indicate that quadratic systematic sampling outperformed SRS in most instances and proved to be especially efficient in the presence of a long-ranged covariance function and high sampling intensity (i.e. short distances between observations).
Lawsonia intracellularis : utvärdering av provtagning med tops : utvärdering av provtagningsteknik med tops vid diagnostik av Lawsonia intracellularis hos tillväxtgrisar
Lawsonia intracellularis is an important pathogen in the intestine, causing diarrhea and
retarded (or poor) growth in pigs.
Diagnostics is based on sampling of small amounts of faeces. Several publicated scientific
papers mention the use of faecal swabs as sampling material for diagnosis in experiments and
in prevalence studies. Therefore the need of an evaluation of this sampling technique is
urgent since, to our knowledge, this has not previously been done. Here reported work
compare the use of rectal swabs for feacal sampling, with sampling and analysis of 0.1-0.2
gram of faeces.
The studie included twelve herds with a case history of earlier or ongoing problems with
diarrhoea where Lawsonia intracellularis could be suspected as the causative agent. A total
of 120 growing pigs where examined.
Riskbaserat provtagningsprogram för mikroorganismer i Gäddviks vattentäkt
Risk-based sampling program of microorganisms in the water source in northern SwedenAfter several disease outbreaks caused by parasites in the drinking water during the last years, it is more essential than ever to insure that the water supply companies have enough barriers to counteract the presence of microorganisms in the outgoing water. It is also discussed whether climate changes such as increased precipitation can have a connection to the increased cases of parasites in water sources. The water source at Gäddvik is Luleå municipality?s largest and provides drinking water to 64 500 of Luleå?s 74 000 inhabitants. The investigation of microorganisms in the water source, especially in the Lule River has not been as prioritized as the sampling of chemical parameters.
Below-the-line : En fallstudie av små företags tillämpning av marknadskommunikation med fokus på below-the-line metoder
This study aims to research how small companies that operate on the Swedish home electronic-market utilize marketing communications to communicate their message. The focus of this study has been to research these companies use of below-the-line activities in their marketing communications. Interviews have been conducted with representatives from each of the three companies Neonode, Jens of Sweden and Tonium, that compose the selection from the population in this study. The use of below-the-line activities in small companies is mainly motivated by lower cost, which suit small company budgets. Below-the-line activities are also used for branding and the creation of credibility among the consumers when the target audience does not yet know the brand.
Advantages and disadvantages of different observation methods on a troop of wild olive baboons at a river in Southern Kenya
Every observation method has its advantages and disadvantages and a well-adopted method gives more reliable results. Factors affecting the choice of the most appropriate methods for recording foraging behaviours include species, group size, environment, seasons and age. The focus for this study was to determine which method is most appropriate for studying the foraging behaviour of a troop of 89 olive baboons (Papio anubis) living in a riverine forest by the Southern Ewaso Ng'iro River by Lale'enok Resource Centre in Kenya. To determine this, a literature study was carried out to compare methods from monkeys and apes. I found instantaneous sampling was the most common method with intervals of 5 minutes in most cited studies.
Sjuksköterskors kunskap om perifert inlagd central venkateter (PICC-line)
A peripherally inserted central catheter (PICC line) is a catheter that is inserted through a peripheral vein in the arm and then on to a central vein in the chest. It is used to give injections and infusions and to take blood samples of patients who need treatment for longer periods.The aim of this study was to investigate nurses' perceived knowledge of the care and use of PICC line in wards where PICC line does not occur daily. The aim was also to investigate if the nurses expressed a need and wished for more knowledge to be able to use PICC line, and if PICC line is not used investigate the cause of that.The study was of a descriptive design with quantitative approach. An online survey was answered by 40 nurses from five wards at a university hospital in central Sweden.A large number of the nurses who responded to the survey reported that they lacked knowledge of the care and use of PICC line. Despite this, three-quarters of the nurses usually use PICC line at the infusion / injection / blood tests on patients with PICC line, if they are cared for in their ward.
Utveckling och utförande av frekvensstudie vid Rapid Granulator AB
The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.
Leaf area index in Vittelaria Paradoxa parklands in Burkina Faso estimated by light interception and leaf sampling
Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.
Sedimentprovtagning av dagvattendammar som ett alternativ till flödesproportionell vattenprovtagning
Stormwater run-off from surfaces such as roads or rooftops is often polluted with heavy metals and nutrients. Many of these substances can cause great damage in biota if they end up in the recipient. In Sweden constructed wetlands and ponds for treatment of stormwater are frequently used, since research has shown that these treatment ponds are reducing stormwater pollution considerably to a low cost. The knowledge of these pollutant removal mechanisms and how follow-up and assessment of the ponds should be performed is still limited.To determine the pollutant removal efficiency of the stormwater ponds it is recommended that flow-weighted water samples are collected from both the inflow and the outflow of the pond. This method demands considerable resources of time and money for installations and analysis.
Mikroföretags kommunikationshantering, off- och on-line, på
konsumentmarknaden: en fallstudie på två företag
The purpose of this thesis was to highlight how different aspects of market communication are used when micro companies choose to use both Internet and store selling activities towards the consumer market. The thesis dealt with off-line and on-line communication considerations with focus on advertising, interactions, and relations. In order to achieve this purpose a case study was conducted, that revealed that the companies acted according to theories. The conclusions drawn from the thesis were that companies tended to rely on traditional ways of dealing with advertising and interaction. We could also see that relations were created as a result of unconscious behavior and that the Internet activities still were on a basic level..
Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms
This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.
Personalen i frontlinjen som varumärkesbärare : En studie inom träningsanläggningar
The purpose of this research aims investigate whether front line personell are brand carriers who can affect the customers brand experience. This present study focuses on commercial fitness centers in Kalmar. Like brands, training is taking part in people?s everyday lives; fitness centers are offering the customer a wider range of group training.This thesis is based on a qualitative approach whereby eight interviews have been carried out with two members of the board and six employees of the front line. Additionally, this thesis is also based on three focus groups with four customers, representing the majority of each fitness centers.The research findings highlight that the front line employees are very important as they are seen as the brand; therefore the front line employee?s personality and behaviour will influence the customer?s view of the brand.
"Delaktighet är engagemang" : En kvalitativ studie om upplevelsen av delaktighet hos mellanchefer inom hemtjänst
The aim of this qualitative study is to examine the experience of participation among first line managers within community home care. The study is based on eight interviews with first line managers operating in a metropolitan area in Sweden. A majority of the interviewees worked in private companies.We have used two theories to interpret our empiri: Lean Production and Human Resource Management. The analysis resulted in seven themes: economy, leadership, participation, view on the organization, first line manager, private or municipally operated organization and expectations on the manager. Our results showed that all the interviewees experienced that they were participant in the organization.
Trenders påvekan på Line Extension - En fallstudie av Skånemejerier
The purpose of this study is to look at the line extensions of the Swedish dairy company Skånemejerier. We have chosen to focus on how trends in ecological products and Functional Food influence the line extensions. The competition in the food sector have made it harder for companies to be seen in the market area and the companies have to make their brands more visible. That is one of the reasons why companies work with line extensions. The study is based on a qualitative approach because we wanted to come closer to our subject in order to establish a greater understanding for the case itself.
Methods for Locating Distinct Features in Fingerprint Images
With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.
