Röjning är en skötselåtgärd som påverkar det framtida beståndets utveckling och skördeutfall. Olika och delvis motstridiga mål måste beaktas vid röjningstillfället. I praktiken blir många bestånd röjda mer än en gång. En orsak till upprepad röjning är att det kan uppstå behov av förnyad lövröjning när stubbskott har vuxit ifatt barrträden. Röjningens utförande kan också påverka nästa skötselåtgärd, dvs.

Att föda barn är för många kvinnor en av de största händelserna i livet. Ett flertal faktorerpåverkar kvinnans upplevelse såsom smärta, kontroll och stöd. Att få kontinuerligt stöd underförlossningen påverkar både förlossningsupplevelsen och förlossningsutfallet i positivriktning. Det finns flera studier om förlossningsupplevelser men få som enbart fokuserar pånegativa upplevelser av förlossningen. Studier som beskriver vad kvinnor med en negativförlossningsupplevelse upplever skulle vara viktigt för att få en mer positiv upplevelse saknashelt.

This study investigates the difficulties that may arise for students as a consequence of differences that exist in mathematics education between different educational systems. The questions asked are when and why difficulties as a consequence of differences in writing or types of student problems may arise and in which way teachers and students attend to these difficulties. The focus is thus on the written parts of mathematics education and the questions are asked within the frame of general upper secondary education.In order to answer these questions, a sociocultural perspective based mainly on Sfard?s (2006) participationist theories together with Vygotsky?s (1999) general theories on development and learning is used. An important analytic tool is the discourse concept which in this context means a type of communication that brings some people together while excluding others from the communication.

The dog has often served as a model animal for humans in scientific studies. This is due to the fact that dogs are susceptible to a wide range of diseases which also affect humans. One example is cancer, a condition that affects dogs as well as owners. Neoplastic diseases account for 18-23 % of all deaths in dogs (Bonnet et al., 2005 and Jagielski et al., 2002). Mammary tumor, or tumor of the breast, is the most common tumor form in intact dogs and women (Im et al., 2013). Mammary tumors originate in the udder, and are classified according to their histological characteristics.

Fossila bränslen har sedan de upptäcktes konkurrerat ut biomassa som den huvudsakliga energikällan. Framförallt i trafiksektorn har drivmedel som härstammar från fossil olja varit dominerande. Främst på grund av deras fördelar mot biomassan såsom tillgänglighet, pris, energidensitet och enkelhet att användas i en förbränningsmotor. Men dessa drivmedel innehåller kolatomer som inte längre är en del av det naturliga kretsloppet och vid förbränning leder detta till nettotillskott av koldioxid till atmosfären. Utsläpp av koldioxid utgör den största antropogena inverkan på den accelererande växthuseffekt världen upplever vilket kommer att medföra förödande klimatändringar.

Mind the gap encourages you to beware of the interspaces. The project seeks to defend the gaps that occur in time and space and encourages the reader to care about the interruptions of the routine-like and planned, whilst also opening up a discussion about interaction and participation. Mind the gap is a project about the many opportunities the public space has in the contemporary city. What you have in front of you is the result of this project. As society constantly changes, new and different needs arise in the city and it is necessary that architects and planners understand and adapt to these changes. They have to be able to develop new ways of thinking and to challenge established perceptions of what the public space is and should be. This means being able to see that the public space could be different and to recognize the potentials for it to change. This project examines the underlying ideals of urbanism and investigates the potentials of the City when shaped by these ideals.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.
