En ml vatten från havsvatten innehåller ungefär 1 miljon bakterier och 10 miljoner virus. Prover från Östersjön har undersökts genom dataanalys för att studera dynamiken mellan bakteriers adaptiva immunförsvar – CRISPR - och virus.Bacteria play a major role in biogeochemical cycles in the ocean. Bacteriophages are estimated to cause the deaths of more than a fifth of all marine bacteria every day and the dynamic between bacteria and virus therefore have huge ecological impact. CRISPR-Cas systems work as an adaptive immune system for bacteria that protect them against viruses. Spacers acquired from viral sequences can make t

Today, Swedish women have one of the highest participation rates. In the nineteenth century, however, virtually no married women were recorded as working. Their participation rates started rising around the turn-of-the-century. Using full-count microdata from Swedish national censuses for the period 1880-1910, this paper aims to estimate the effects of various determinants on female labour supply.

När man pratar om industriellt underhållsarbete är mänskliga fel ett viktigt ämne att hantera. Olika typer av mänskliga misstag till följd av farliga tillstånd i vissa speciella parametrar, s.k. Performance Shaping Factors (PSFs) introducerar nya och oförutsägbara risker. Detta examensarbete presenterar en metod som, till skillnad från många metoder som finns tillhands idag, är tänkt som en enkel When discussing industrial maintenance, human error is a topic that easily comes to mind. Slips, lapses and mistakes due to hazardous settings of critical conditions referred to as Performing Shaping Factors (PSFs) introduce unforeseen and unanticipated risks. Unlike several tools to date, the methodology presented in this master thesis is thought to serve as an easy and fast way to identify risks

Skin ages as a result of the failure of several mechanisms that are triggered by both internal and external factors. The accumulation of damaged proteins is an effect that comes with age due to the dysfunction of the proteasomes and their decline in activity, which leads to dull looking skin. In addition, as we age the effects seen on are skin includes the formation of age spots as well as hyperpi

The aircraft of today use electrical fly-by-wire systems for manoeuvring. These safety-critical distributed systems are called flight control systems and put high requirements on the communication networks that interconnect the parts of the systems. Reliability, predictability, flexibility, low weight and cost are important factors that all need to be taken in to consideration when designing a saf

Allt fler organisationer använder sig idag av det digitala kommunikationsverktyget “chatbots” i sin kundtjänst för att kommunicera med sina användare. Den främsta anledningen till att chatbots i form av kundtjänst blir allt vanligare på organisationers webbsidor är att de kan effektivisera verksamheten och därmed reducera kostnader. Det har alltså skett en förändring i hur organisationer kommuniceToday, organizations are using the digital communicative tool ‘chatbot’ in their cus-tomer service to communicate with their customers. The main reason for using this new technology on organizations’ websites is that chatbots can make the customer service more efficient, hence reduce organizational costs. As a result, the chatbots have altered the way organizations and customers communicate with o

In the light of lean methodology, World Class Manufacturing requires continuous improvement in analyzing the losses to eliminate the wasteful resources and to boost the overall productivity. However, the standardized loss structure should be well-balanced to be general enough to cover the whole manufacturing procedure while being specific enough to point out the real issues happening for further i

Sverige, ett av de minst korrupta länderna i världen, har fått återkommande internationell kritik gällande ineffektivitet i svensk mutlagstiftning när det kommer till straffrättsliga sanktioner mot företag som begått mutbrott. Detta på grund av bristen på rättspraxis där företag gjort sig skyldiga till vårdslös finansiering av mutbrott. Kritiken har bland annat kommit från EU-kommissionen då SveriSweden, as one of the least corrupt countries in the world, has been subject to recurrent critique regarding inefficiency in its bribery legislation, especially regarding sanctions against corporates. The reason behind this is due to the lack of case-law when it comes to companies being directly or indirectly responsible for bribery. The European Commission have criticised Sweden due to the fact t

Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. A reduction in the storage size of each collision ev

This report describes the development of a new design for a small surveillance camera that would bring new opportunities for surveillance in carefully decorated environments. The target group was specified to high-end stores; luxury retailers. This specific target group has a great interest for new products and trends and stores in the lower price segment are often inspired by the high-end stores

In order to exploit the renewable energy (RE) and climate mitigation potential, transaction costs (TCs) of implementing RE technologies need to be better understood and eventually scaled down. The objective of this thesis is to identify and analyze the nature of TCs borne by obliged parties under the recent “Feed-in Tariff” (FIT) scheme in the United Kingdom. In addition, the findings are compared

This study sought to investigate the effect of microplastics on Mytilus edulis’s ability to filtrate water. The mussels were sampled at Hanö bay located in the Baltic Sea, and were transported to a controlled environment. The mussels were exposed to three different solutions, one containing a concentration of 1 000 Microbeads (diameter 10 μm) per liter, one containing the same amount of plastic be

I Sverige finns det ingen lagstadgad skyldighet att bistå nödställda personer. Undantag finns i vissa situationer när det framgår av lag eller allmänna principer. Att se på när en okänd människa drunknar utan att hjälpa till, trots att personens liv enkelt kan räddas är idag straffritt. Syftet med denna uppsats är att med hjälp av en rättsdogmatisk metod utreda om en civilkuragelag bör införas i SIn Sweden there is no statutory duty to rescue distressed persons. Exceptions can be made when this is required by a special law or by legal principles, but watching an unknown person drown when his life easily can be saved is not illegal. The purpose of this essay is to, by using a traditional judicial method, examine whether this behaviour should be criminalized or not. If the duty to rescue di
