Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report,  the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.

Forskningsfråga: Hur påverkas allivsbutikerna av att få Lidl eller Netto som granne och vilken betydelse har allivsbutikernas val av åtgärder för att differentiera sig för hur väl de lyckas konkurrera med hard discount-butiken? Syfte: Syftet med uppsatsen är att skapa förståelse för hur traditionella allivsbutiker påverkas av att en aktör med utpräglad lågprisprofil (hard discount) etablerar sig i närheten. Vidare är syftet att beskriva hur allivsbutikerna, genom olika åtgärder, arbetar för att differentiera sig från hard discount-butikerna och hur val av åtgärder inverkar på hur väl allivsbutikerna lyckas i konkurrensen med den nya aktören. Metod: Vi har, genom tio besöksintervjuer och tjugo telefonintervjuer med handlare och butikschefer i allivsbutiker, samlat in kvalitativ och kvantitativ data om hur dessa butiker påverkats av att få Lidl eller Netto i sin närhet och vilka strategier de använt för att möta den nya konkurrenten. De teorier som används vid analysen behandlar konkurrensstrategier och hur allivsbutiker påverkas av lågpristrenden i allmänhet och hard discount i synnerhet.

One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.

LRF Konsult is a big consulting-firm with offices located all over Sweden. The corporation offers a wide range of services and a lot of the customers are small businesses active within the green sector. An analysis of the corporation made in 2006 showed that one of LRF Konsults weaknesses is that many customers are unaware of the wide range of services that LRF Konsult offers. The internal communication is believed to play a big role in marketing these services. Therefor, the objective of this thesis has been to investigate why the transfer of customers between accounting consultants and business advisors is not greater and how this can be improved.

Nematode-transmitted plant viruses (such as nepoviruses) cause great economically losses in commercially important plants such as tomatoes, grapevines and raspberries all over the world. To avoid spread of the viruses the interest in mapping the viruses has increased. One of the important nepoviruses infecting European red raspberries (Rubus idaeus) is Tomato black ring virus (TBRV). TBRV has earlier been confirmed in raspberry samples from Belarus by ELISA and the aim of this bachelor degree project was to confirm these results by amplifying, cloning and sequencing the coat protein (CP) gene of the virus. In total eight viral cDNA samples, from two different raspberry samples, were amplified and sequenced.

Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.

During my education I have frequently noticed that pupils do not like science or find it hard and dull. The purpose with this investigation is to find out how pupils experience their science education and if they can understand the arguments for studying the subject at school.I have made a questionnaire study among pupils in grade 8 and 9. After analyzing their answers I have interviewed some of the pupils to get answers on further questions.The investigation resulted in conclusion that pupils have hard to connect their science-education to their everyday lives. The most important element in forming the pupil?s opinions about science is their relation to the teacher and how the lessons are set-up.The following questions will be answered in this paper:Do pupils understand why they have science at school?Can the pupils see the use of scientific knowledge in their everyday life?How do pupils look upon their science education?.

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Syftet med vår uppsats är att genom en teoretisk och empirisk grundad diskussion undersöka vilka strategier som står till buds för de svenska dagligvarukedjorna vid en branschförändring på grund av en nyetablering av en hard discount aktör. Uppsatsens utgångspunkt är en abduktiv ansats där en växelverkan mellan teori och empiri är central. Vi har genom en kvalitativ metod samlat in primärdata genom elva delvis strukturerade intervjuer. Vi presenterar intervjumaterialet i ett empirikapitel och tillsammans med en förstudie kopplas sedan detta underlag till relevanta teorier. De teorier som vi funnit vara av intresse för vår studie är bl.a.

Aim: Culture exists in every organization, whether you actively work with it or not. Old cultures often carry traditions and are hard to change. The purpose of this thesis is to describe Gävle Galvan from an organizational point of view and also to investigate the culture from a gender point of view.Method: The thesis is written with a qualitative and narrative approach. I have taken part in three person?s stories through interviews and thereby created picture of their everyday work on Gävle Galvan.

I den här uppsatsen ville jag, med hjälp av olika reklambilder för disk- och tvättmaskiner, visa att ?miljö? sedan början på 2000-talet alltmer blev en resurs i kommersiell varureklam.Hur naturen och miljön används som ett försäljningsargument idag påverkas av en miljödiskurs som sedan sena 80-talet har fortsatt att utvecklas fram till nu, 2009. Hur den diskursen ser ut formar mycket av dagens varureklam och skapar de konventioner som står till grund för den. Ett stort problem med ?miljövaror? har varit sättet som de marknadsförs.

AbstractI believe that everyone have the right to understand and be understood. It doesn´t matter if you are an immigrant, suffer from dyslexia or just don´t like to read.In this study I test the difference between a normal written and an easy-to-read routine. I want to know if there is a way to improve a routine in such a way that even people without pre-understanding can comprehend the content.Routines are an important part in many organisations. Staffroutines in nursinghomes don´t exist just to ensure that caretakers are being taken care of in the right way according to the rules and wishes of the organisation. They also exist to make the work with people who suffer from dementia easier for the staff.Routines are in other words very important.
