Prevalence of toxin-producing strains and antimicrobial resistance in isolates of Staphylococcus hyicus from pigs with exudative epidermitis and from healthy pigs
Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.
Dietrich Bonhoeffer som motståndsman och Svenska kyrkan. Ett påbörjande av en kartläggning av deras kontakter och motståndsrörelsen i allmänhet
The overall purpose of the essay is to initiate a survey and highlight, on the basis of sufficiently material, the dealings between Dietrich Bonhoeffer as a member of the resistance and the Swedish Church and/or its representatives. The purpose of the survey is to structure Dietrich Bonhoeffers activities in Sweden and highlight its implications.The following research questions have been used:1: What was Dietrich Bonhoeffer doing in Sweden and what persons did he meet?2: What was the role of the Swedish Church during the Second World War? 3: What was the impact of Dietrich Bonhoeffers visits to Sweden?In conclusion, this study of the contacts between Dietrich Bonhoeffer and the Swedish Church has shown: Dietrich Bonhoeffer was in Sweden on two occasions. He met representatives of the Swedish Church, which was engaged in issues related to ecumenism, resistance and peacework. Although the persons he met were representatives of the Swedish Church they sometimes acted as individuals with a Christian philosophy.
Motstånd till förändring
The aim of this study is to compare attitudes to change among innovation and economics students and teachers at one of the universities in Sweden.Data about students? and teachers? attitudes to change was gathered using a survey.Keeping in mind that knowledge can lower ones resistance this study is based on a hypothesis that individuals from the innovations program have a lower resistance to change. The study is also based on earlier research in regards to comparisons between students and teachers.The results of the study show that teachers have less resistance to change than students. Individuals in the innovation program are however less resistant to change than individuals in the economics program.One can discuss whether or not results of the study show that the hypothesis is correct.The difference between individuals in the economics- and the innovation program are statistically significant and has moderate effects in reality. The differences between teachers and students are statistically significant but only have a small effect.It is however a starting-point for future studies that will possibly explore the subject more profoundly..
Frihetens regim : Nyliberal subjektivering hos Foucault
This paper focuses on the role freedom plays in Michel Foucault?s analyze of liberal and particularely neoliberal governmentalities. From his perspective, neoliberalism operates through the strategic production of entrepreneural subjectivity and distribution of self-governing. Here autonomy is central for governing, which raises questions about what freedom can mean at all in Foucault, and how resistance can be possible. Through Foucault?s thinking on liberal freedom, we can gain a better understanding of his philosophy on subjectivation and resistance..
Refugia som metod för att minska utvecklingen av anthelmintikaresistens hos får
Anthelmintic resistance is a major problem in sheep husbandry all over the world. One way toslow down the development of anthelmintic resistance is to keep part of the parasitepopulation in refugia (unexposed to drugs) which will maintain the genes for susceptibilitywithin the population. Climate, type of parasite and drenching regimes effect the size of therefugia. Dilution of resistant with susceptible parasites, targeted treatment and targetedselective treatment are all management strategies that employ refugia. Dilution is possible butcomplicated.
Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
Antibiotikaresistens - djursjukskötarens roll i att förhindra spridningen
There are several different kinds of bacteria that has developed resistance against the antibiotic agents used in todays medicine. Most of them has evolved from the human health care but several of them has gone over to also cause problems in the animal health care. They often occur as nosocomial infections and the greatest risk of exposure to them is during health care. Since infections with a resistant bacterium can be difficult to treat, it is desirable to prevent this spread, especially since an animal treated in a hospital often is more susceptible to infection, due to their primary condition. In Sweden the current resistance situation is good and is yearly monitored by the Swedish Veterinary Antimicrobial Resistance Monitoring (SVARM) programme.
Utomhusgym, några fördelar? : En studie om affekter vid styrketräning inomhus respektive utomhus
PurposeThe aim of the study was to examine the affects perceived by young people aged 18-19 years old after resistance training outdoors versus resistance training indoor. The aim of the study was also to examine if the rate of perceived exertion was affected by whether the resistance training took place outdoors or indoors. What immediate affects are perceived in conjunction with resistance training outdoors and indoors in people aged 18-19 years?What immediate affects are perceived after resistance training outdoors compared to equivalent resistance training indoor in people aged 18-19 years?What perceived exertion level can be seen in conjunction with resistance training outdoors compared to equivalent resistance training indoors in people aged 18-19 years?How does exercise habit correlate with affects and exertion in conjunction with resistance training? Method22 pupils in a secondary school conducted two resistance training sessions, one outdoors and one indoor. A questionnaire about their mood and exercise habits was answered before and immediately after the training session. Rate of perceived exertion rate was also included in the questionnaire the participants received after the workout.
Finns det daglig variation i resistans i de nedre luftvägarna hos häst?
Among researchers it has been established since decades that humans and animals have an internal biological clock that controls certain physiological mechanisms. One example regarding humans is the impairment of lung function during the night, causing the phenomenon ?nocturnal asthma? among asthmatics. Only a few studies concerning respiratory circadian rhythm in horses have been done previously and they showed a daily variation in horses with a chronic or an acute respiratory disease. The technique used in those studies was the conventional technique, which is invasive and less sensitive than the technique used in this study.
Beräkning av återmatad bromsenergi på Malmbanan
Energi är en resurs som måste användas effektiv för att undvika onödig negativ miljöpåverkan och utgifter. Återmatning från nedåtgående malmtåg till uppåtgående malmtåg leder till en effektivisering i energiutnyttjande. Beräkningen av den återmatade energin utgår ifrån tågets lägesenergi och förlusterna från räls, lutning, vind och kurvor. Totalt kan återmatning av energi ge en besparing på 20 % för enkelspår och 20 % respektive 21 % för dubbelspår. Dubbelspår kan ha mer trafik än enkelspår men förhållandet mellan konsumerad och återmatad energi är i princip den samma.
Åkertistel : biologi och icke-kemisk bekämpning
A growing problem in Swedish herbicide free agriculture, the Canadian thistle has been the object of several new trials, seeking methods for non-chemical weed control. The new trials have mainly confirmed earlier experiences; that the most successful methods of control are springtime ploughing, repeated cutting and competition from a stout crop. Row hoeing has also been proven effective. As opposed to earlier recommendations, half season fallow has shown to be a risky and often ineffective method of control. Trials regarding biological methods have shown that above others thistle rust (Puccinia punctiformis) may have the potential of controlling Canadian thistle the future.

Determination of anthelmintic resistance of Haemonchus contortus to three classes of anthelmintics in a Kenyan sheep flock based on results from faecal egg count reduction test
Haemonchus contortus is the most important bloodsucking gastrointestinal nematode in small ruminants worldwide. It is often controlled by anthelmintics. Even though other methods to control are available, the most efficient way to treat an animal with clinically manifested haemonchosis is to use one of the available broad spectrum anthelmintics: benzimidazoles (BZ), macrocyclic lactones (ML) or imidothiazoles-tetrahydropyromidines or the narrow spectrum drugs salisylanilides or nitrophenols. Anthelmintic resistance (AR) against all groups of anthelmintics in nematode parasites has been reported from many countries, and even multiple AR has been observed. In this study I have investigated the resistance levels to all major classes of broad spectrum anthelmintics in a naturally infected flock of sheep of Red Maasai sheep (RM), Dorper sheep (D) and their offsprings on a research farm in Kenya.
EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering
Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.
An image-based method for identification of new inhibitors of Signal Transducer Activator of Transcription 1
Background: Chemotherapy and radiation resistance are major causes of failure in cancer treatment. The response to treatment in cancer cells depends on several mechanisms and pathways such as Janus kinases-signal transducers and activators of transcription JAK/STAT pathway. STAT1 was the first described transcription factor in the STAT family. STAT1 is activated by stimulation of signaling proteins such as type II interferon (IFN- ?) and the activated STAT1 translocates from cytoplasm to nucleus.
Inre motstånd : En okänd fiende på vägen tillbaka från utanförskapet?
Inner resistanceThe aim of this study was to investigate the existence of an internal resistance to a work-related change in people who are long-term sick, and if this is related to an identification as ?long-term sick?. A second purpose to the study was to research in which way this internal resistance to a work-related change manifests and point to possible solutions. A qualitative study was conducted with interviews of experts and people on sick leave to illuminate the subject. The main result was divided into interviewed groups.
