Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.

Syftet med uppsatsen är att öka förståelsen för taktisk kompetens som omhändertar den inneboende komplexiteten i militär verksamhet. Problemet häri är att kompetens kan anses vara något sällsynt och att inkompetens snarare är normalbilden.Uppsatsen tar sig an detta arbete genom att operationalisera Bertil Rolfs teorier om militär kompetens och Stephen Biddles teori om the Modern System. Ur detta teoretiska utblicksblicksfönster utfaller ett analysfilter bestående av kategorierna praktisk kunskap, professionell kunskap, regler och praktik inom institutioner och traditioner. Huruvida dessa kan utgöra en grund för förståelsen av taktisk kompetens analyseras därefter med stöd av Israel Defense Forces taktiska prestationer under det andra Libanonkriget 2006.Resultatet är att taktisk kompetens är möjlig att förstå utifrån förutsättningarna att hantera den föränderliga helheten. Taktisk kompetens handlar om de organisatoriska villkoren att kritiskt granska och reflektera över rådande förhållanden och förutsättningarna för att åstadkomma förändring och utveckling.

In 1998 Sweden accepted the Treaty of Amsterdam which contained a development of the common foreign and security policy (CFSP) towards a European security and defense policy (ESDP). This thesis aims at studying the decision making process behind the Swedish foreign policy decision to further develop its security policy within the European Union. The purpose is to explain which factors and conditions that did affect and influence the Swedish foreign policy decision. The research applies foreign policy analysis, a theoretical perspective that analyzes both domestic and international conditions using different levels of analysis. The research methods being used has been qualitative as well as quantitative, complemented by interviews, since the research is a process tracing case study.The thesis conclusion is that the Swedish decision is explained by several factors.

On the 12:th of April 2011, the Swedish tabloid magazine Expressen publishes a story, claiming that Ola Lindholm, presenter of critically acclaimed TV-show ?Wild Kids? has been suspected and apprehended on cocaine allegations. The serious allegation called for Ola Lindholm to defend himself against the allegations. His only public response was a blog-post where he claimed his innocence, albeit with some reservations.  The purpose of this paper is to analyze Lindholm?s rhetorical defense.

The 17th October 2014 the Swedish Armed Forces (SwAF) introduced an intelligence operation in Stockholm archipelago after receiving credible observations regarding illegal underwater activities. Following the data collection and associated analysis it could be stated with certainty that a foreign submarine had violated the Swedish territorial waters. Media depend on SwAF to provide them with accurate information due to the confidentiality in these matters and the general area of investigation is therefore how the actions of the Swedish Armed Forces, in the submarine incident 2014, were portrayed in the Swedish media. Newspapers and blogs of defense policy represent the media and the thesis is based on the theories constructed by Graham Allison, the rational actor, organizational behavior and governmental politics. Furthermore, it is relevant to examine if there are any similarities or differences in how the submarine incident is illustrated, and what may be the reason for any possible occurrences.

ABSTRACTThe aim of the observation study was to examine the dental hygienists working tasks and the time they used carrying them out. Four dental hygienists where observed during four days each. The total time the dental hygienists used with patients during sixteen fulltime days come to a sum of 89 hours of the possible 111 hours. Twelve hours was late cancels and time when patients didn?t come to their appointment and ten hours were used for meetings.

Abstract  Title: Från neutralitet till öppenhet? ? En studie av säkerhetspolitikens utveckling i Sverige efter kalla krigets slutAuthor: Jens KindhSupervisor: Patric LindgrenLinnaeus UniversityDepartment of Political ScienceSpring term 2012 When the Cold War ended, a new security situation was unfolded in Sweden. The purpose of this thesis is to describe and compare how the Swedish security policy is organized and how it has changed since the Cold War ended. To do that, I?m going to try answer the following questions:How is the Swedish security policy organized?What defence resolutions have affected the Swedish security policy after the Cold War ended?How has different political actions made its impact on the Swedish security policy after the Cold War ended?My theory is to try explain how the Swedish security policy has changed after the Cold War through a realism security perspective called traditional security, which refers to a realistic construct of the states security policy.

The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur). The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas. The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected. The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands. The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.

Den svenska rennäringens primära inkomstkälla är försäljning av renkött. Syftet med denna uppsats är att undersöka ett antal faktorers inverkan på utbudet av renkött. Metoden ordinary least square har använts för att göra en ekonometrisk studie baserad på statistik för åren 1980-2003. De faktorer som testats är total ersättning, vilken inkluderar avräkningspris samt kvantitetsbaserad subvention, och renstammens storlek. Resultaten i vår undersökning visar att total ersättning inte är signifikant på någon testad nivå, däremot fann vi att renstammens storlek hade positiv korrelation med utbudet på renkött.

In a time when concern for the environment is a topic that is met with both love and hatred, organic goods and services become increasingly common on the market. Communication efforts with the purpose of increasing the proportion of organic products consumed are being conducted by both private and public actors. However, achieving attitudinal and behavioral change within complex areas such as this comes with many difficulties.Within public opinion change, a common way of achieving a change in behavior is to use fear appeals and scare tactics. Earlier studies have shown that messages prompting a low level of fear can be more effective than messages prompting a high level of fear, since a high level of fear tends to raise defense mechanisms in the consumer. The purpose of this essay is to examine whether fear and defense mechanisms is a problem when it comes to making consumers choose organic products, as well as studying whether messages prompting low levels of fear are more effective than those prompting high levels of fear.This quantitative study is conducted in the form of a questionnaire-based experiment, comparing the effectiveness of two messages prompting different levels of fear.

Report of diploma work conducted at the Swedish Radiation Safety Authority (SSM) as part of the bachelors program in Nuclear Engineering at Uppsala University.All nuclear power plants in Sweden are obliged to report any deficiency in their barriers or the defense in depth in obedience to SSM?s regulations concerning safety in nuclear facilities. In addition, there is an international system for reporting such events. The purpose of this thesis is to study the Swedish report system and to analyze the differences between Swedish and international event reporting.In the Swedish system, SSM?s regulations are effectuated by means of event reports classified as category 1-3, designed individually at each Swedish facility.

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..
