Diatermirök- Det perioperativa teamets arbetsmiljö

BackgroundDiathermy is the most commonly used surgical instrument in the surgical area today. Diathermy is used in surgery to cut and coagulate tissue. The use of diathermy releases chemical substances in to the environment in the form of diathermy smoke. Research shows that these chemical substances pose health risks to both staff and patient exposed to the smoke. To protect the interdisciplinary, perioperative team from the smoke, smoke evacuation systems can be used.ObjectiveThe purpose of the study is to highlight the work environment of the perioperative team when working with diathermy smoke.MethodThe study is meant to be implemented as an empirical descriptive sample survey.

Detection of mutations in dihydropteroate synthase (dhps) and dihydrofolate reductase (dhfr) in Plasmodium falciparum in eastern Sudan

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

Systemarkitektur och implementering av standardsystem : En fallstudie vid Linköpings universitetsbibliotek

The use of ERP in organisations is very popular and many companies have embraced this paradigm without really questioning why. Problems therefore often arise and cause high costs which is a result of poor planning. The paradigm also has its origin in the traditional architectural design that creates a system that has difficulties to adapt to organizations that are constantly evolving. The purpose of this study is to provide a different view of how IT-systems can operate within an organization and show how standard systems can be structured. We emanated from a case study at Linköping University Library, where we studied the implementation and integration of a standard system called Symphony.

The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

GRÄNSSNITTET OCH ANVÄNDARNA En undersökning av två gränssnitt mot en bibliotekskatalog.

The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..

Effect of cow traffic system on cow performance and AMS capacity

Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.

A Study of the Sales Process of ERP Systems: Wasteful Management or Managing the Wasteful?

A description and analysis of the sales process of ERP systems is presented; also the consequences for the parties involved are discussed. The chosen methodological basis is an inductive research design consisting of a case study based on interviews. The analysis of the empirical data is done with a proposed analytical framework. Based on the agency theory, the analysis is tightly knitted together with opportunism. There are three controlling factors: relationships (relationship marketing), contracts (principal-agent theory), and competition.

A study to optimize insulation thickness for stock-, industrial- and office-buildings for external walls and roof in an economical perspective has been conducted on behalf of DynaMate. DynaMate?s role is to maintain all Scania?s buildings. Analysis has also included other parts of the building envelope, such as windows, exterior doors and industrial doors. In this thesis, three different types of exterior wall constructions has been investigated, these are a sandwich design consisting of sheet metal and a another one consisting of concrete, as well as a wall of concrete with a coating of plasters.

Milk yield and composition in Swedish landrace goats (Capra hircus) kept together with their kids in two different systems

Swedish goats are mainly held for cheese production and therefore, both milk quality and composition are of great importance for dairymen. Today, only few data exists on milk composition from Swedish dairy goats and the casein content is still unknown. One way to reduce the work load for goat farmers and increase animal welfare can be to keep goats and kids together for longer periods. The aims of this study were to investigate how milk yield and composition were affected when kids suckled their dams during 8 weeks, and to measure the casein content on farm level by a mid-infrared spectroscopy method, previously calibrated for goat milk. Lactating goats were kept in two different MIX- systems where the dams are both suckled and milked.

The system is built for contact centers and used in different types of organizations. Contextual inquiries with users from six different organizations were held together with interviews with stakeholders of the system. This gave an understanding for how the system is used and the needs to be met in the different organizations were recognized.

Läkemedlet Oxazepam påverkar abborryngel : Exponering under embryonalutvecklingen ger effekter på tillväxt, överlevnad och beteende

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

Implementering av Patientsimulator för Anestesimaskiner

In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.
