For an autonomous system of linear differential equations we are able to determine stability and instability with classical criteria, by looking at the eigenvalues. If the system is stable, all the eigenvalues have negative real part and if the system is unstable, there exist at least one eigenvalue with positive real part. However, if it were to be nonautonomous, the criterion fails. There exis

Framtidens generation av solceller innehåller nanotrådar, men vilka risker kan materialet utgöra på återvinningsanläggningar? De mycket små semikonduktiva nanotrådar effektiviserar framtidens solceller och det är möjligt att nästa generations solceller kommer bli en vanlig syn i samhället. Men, aktuell forskning pekar på att nanotrådarna har farliga egenskaper för människors hälsa och miljö. Det The rise of solar cells have been received with open arms as a renewable energy resource in Sweden. The new generation of solar cells containing semi conductive type III-V nanowires may pose, without proper safety measures, negative implications on health and the environment. In this study an overview of possible risks is considered in the waste management with solar cells containing nanowires. Al

Technology transfer (TT) is a process that allows countries to acquire, adapt, deploy, localise and innovate technologies from other countries. In the case of international development, TT can help enhance the technology capabilities of developing countries and empower them to boost their economic development.

Många barn upplever oro i samband med smärtsamma eller emotionellt påfrestande procedur. Barn saknar ofta adekvata strategier för smärthantering och är därför extra utsatta. Lekterapi kan anta olika former och syftar till att lindra barns oro och smärta i vårdsituationer. Aktiv distraktion och passiv distraktion syftar till att avleda barnet under proceduren. Det finns även förberedande lekterapi

Contractors who start building based on incomplete documents will always require many costly solutions. The cost to correct mistakes in the beginning of the project is less than the cost to correct mistakes at the end of the project when the admission takes over. Factors that contribute to these large costs are in the planning stage, when transferring information and lack of communication.

Undersökningen kommer att behandla t

Forskning har visat att psykoterapi effektivt minskar interpersonella problem, men få studier har använt interpersonella problem som utfallsmått i en naturalistisk psykoterapikontext. Ett flertal studier har även undersökt om klienters svårighetsgrad av interpersonella problem kan predicera behandlingsutfall, men resultaten går isär. Syftet med föreliggande studie var att studera korrelationen melResearch has shown that psychotherapy is efficient in reducing interpersonal problems, but few studies have used interpersonal problems as a measure of outcome in a naturalistic psychotherapeutic setting.

Bakgrund: LARC är den mest effektiva preventivmedelsmetoden för unga kvinnor, men fortfarande förskrivs i högre grad peroral antikonception. Tonårsaborter i Sverige har minskat, men fortfarande genomförs 11 aborter per 1000 kvinnor årligen bland unga kvinnor under 19 år. Barnmorskan har en stor roll i förskrivningen av preventivmedel. Syfte: Belysa barnmorskans erfarenhet kring LARC för unga kvinn

Internetkonsumtion med frakt utgör en konsumtionsform som har eskalerat i Sverige. Även om detta konsumtionsbeteende inte är miljövänligt är det samtidigt förankrat med kollaborativ konsumtion. Med tanke på att studier saknas där dessa konsumtionsbeteenden jämförs, syftar denna studie därför till att jämföra vad som predicerar ungas intention till, och deras skattade, internetkonsumtion (med fraktShopping online is a form of consumption rapidly growing. Although internet consumption has negative effects on the environment, it is at the same time related to collaborative consumption. Presently, the literature lacks an understanding of youths’ consumption behavior in Sweden as well as a comparison between the two types of consumption behaviors. Thus, the purpose of the present study is to co

The insurance industry is notoriously conservative and has seen comparably few technological improvements in the last fifty years. A wave of new technology- driven insurance firms, or insurtechs, is changing that. By leveraging new technology and offering more customer-centric and innovative products, these firms have captured shares in many insurance markets. One technology — yet to be broadly a
