Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

Drömplanen blev en mardröm En studie om Framställningen av Norweigian och varuvärkesexponering i svensk media under Boeing 787:s kris

Executive summaryThe aim of this study is to examine how the favourability and brand exposure of Norwegian has been damage by their supplier, Boeing 787:s, problems concerning the aircraft Dreamliner. The theoretical framework underlies the content analysis that has been used to operate the study. In total the empirical data rise up to 623 articles that has been collected and analysed from the media archive Retriever. Compares to before and after Boeing 787:s problem with the Dreamliner, the results indicates that the favourability of Norwegian in the Swedish media landscape during the problems was negatively affected. The results also show that there was no increase in brand exposure for Norwergian during the problems.

Riksintresse; Bevarande eller nyttjande : Vindkraftsutbyggnad inom Natura 2000- områden

Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.

Svensk kulturmiljövård : angeläget. tillgängligt och användbart för alla?

The aim of this thesis is to explore from a cultural diversity perspective, students 'views on teachers' leadership styles in the classroom and what style of management students prefer. The study uses a qualitative methodology to interviewed focus groups of students consisting of a total of twelve students at a secondary school in Botkyrka municipality. The corpus was divided into three different groups. Overall, results showed that students seem to prefer an intercultural situational leadership style. This is based on the students expressed need of wanting to be understood on the basis of their cultural background.

Effektivisering av energianvändningen på Skanskas betongfabriker

Syftet med examensarbetet var att finna specifika effektiviseringsåtgärder för energianvändningen vid Skanskas betongfabrik på Svartberget utanför Umeå samt att ta fram generella riktlinjer för energianvändningen på Skanskas samtliga betongfabriker med avseende på effektiviseringsåtgärder. Energianvändningen som analyserades utgjordes av energin som användes vid de processer och verksamheter som fanns på betongfabriksområdet och som användes i eller i anslutning till betongproduktionsprocessen.På betongfabriken utanför Umeå genomfördes en energikartläggning varvid två effektbalanser skapades, en för elanvändningen och en för eldningsoljeanvändningen. Resultatet av energikartläggningen vid betongfabriken utanför Umeå visade att den största delen eleffekt, 25 procent, gick till driften av betongfabrikens uppvärmningssystem och hela 72 procent av effekten från uppvärmningssystemets eldningsoljeförbränning gick förlorad som värmeförluster.Med ett nytt uppvärmningssystem och förbättrad täthet av betongfabrikens lokaler och bättre isolerade spirorör beräknades energin från eldningsoljeanvändningen kunna minska med drygt 50 procent årligen. Även elanvändningen på fabriken kan minskas om ett nytt uppvärmningssystem tas i bruk då energin från eldningsoljeanvändningen ersätter eleffekten som går till de eldrivna värmefläktarna (12 procent av total eleffekt) och värmestavarna (14 procent av total eleffekt).För Skanskas övriga betongfabriker genomfördes en energiinventering med uppföljande telefonintervjuer för att undersöka vilka fabriker som hade högre respektive lägre energianvändning och vad skillnaderna dem emellan berodde på. Resultatet av energiinventeringen och telefonintervjuerna som gjordes för Skanskas övriga betongfabriker visade att fabrikerna med nya fabrikslokaler och med ett uppvärmningssystem från Polarmatic hade absolut lägst energianvändning.

Dam knäckt av kung : En kvalitativ studie om varför misshandlade kvinnor stannar kvar hos männen som slår.

"Dam knäckt av kung" handlar om varför en misshandlad kvinna stannar kvar hos mannen som slår. Det kan ofta vara svårt att förstå och för att ge en bättre bild av detta har jag intervjuat tre kvinnor som har upplevt misshandel av mannen de levt med. Jag har även tittat på olika teorier om till exempel hur en identitet skapas och hur en social verklighet kan förändras under speciella situationer, såsom under misshandelsförhållanden. Bland dessa teorier finns Berger & Luckmann´s (1971) teori om socialisation och internalisering av någon annans synsätt, Goffman´s (1983) totala institutioner och E.Lundgrens (2004) normaliseringsprocess. Jag analyserar mina intervjuer och teorier för att bättre förstå varför kvinnan stannar.

Riktlinjer för att förbättra datakvaliteten hos data warehouse system

Data warehouse system är något som har växt fram under 1990-talet och det har implementeras hos flera verksamheter. De källsystem som en verksamhet har kan integreras ihop med ett data warehouse system för att skapa en version av verkligheten och ta fram rapporter för beslutsunderlag. Med en version av verkligheten menas att det skapas en gemensam bild som visar hur verksamhetens dagliga arbete sker och utgör grundinformation för de framtagna analyserna från data warehouse systemet. Det blir därför väsenligt för verksamheten att de framtagna rapporterna håller en, enligt verksamheten, tillfredställande god datakvalitet. Detta leder till att datakvaliteten hos data warehouse systemet behöver hålla en tillräckligt hög kvalitetsnivå.

En intuitiv & lättillgänglig flyktmask för gruvmiljö

I have always lived around mines and around people work­ing with mines. They are a natural part of my life and, inev­itably, a great interest of mine. When time came to make a decision for a degree project, focusing on the mine context felt as natural as breathing.In LKABs underground mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

Tillväxthastighet och storleksfördelning hos hassel (Corylus avellana)

To increase the knowledge about the growth of hazel (Corylus avellana)and size distribution of the shoots, circumference and stem diameter wasmeasured in a total of 54 clones in two areas in Östergötland. Further, thewidth of growth rings was determined for separate years. The diameter ofthe stems was measured both out from the centre of the stem andperpendicular to the first measure. The stems showed only a weaktendency to have an oval shape (with the longest side outwards from thecentre). The growth model did not improve when the degree of sunlightof clones was taken into the account.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.

Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal

Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

Vandring av vårlekande fisk och jämförelse av fångst mellan ryssja och strömöversiktsnät i Hammerstaån, Stockholms län

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

Detektion av kolvläge i hydraulcylinder med elektromagnetisk metod

The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden. The students in focus were students with reading and writing difficulties, dyslexia or language difficulties such as an other native language. A total of eight students were interviewed. The interviews were analyzed using thematic analysis.

Ledares syn på avhopp inom ungdomsishockey : En kvalitativ studie bland ledare i Norrbotten om vilka faktorer som påverkar avhopp

Dropout among youth players is a problem in Swedish icehockey. Leaders in youth hockey teams work closely with players on an almost everyday basis during season and have a big influence on players and their activities. This study aims to identify possible reasons for dropouts by interviewing coaches and leaders in icehockey clubs. A total of eight coaches and leaders in different ice hockey clubs were interviewed. Results show that the coaches highlight three reasons for early dropout; focus on competition, results and too much training in younger ages..
