Crystal use has existed throughout human history and is a phenomenon that has become more popular globally like the other phenomena that are a part of the new age movement. There is still a great deal of skepticism towards Crystals by people who are not familiar with them due to its unusuality to the stuff that people deem as normal. This paper is based on an anthropological fieldwork consisting of interviews with people that are affiliated with Crystals such as staff at crystal shops, crystal healers & generally people who are interested in Crystals and participant observations in places were Crystals can be located. The material was gathered in a period of 9 weeks in the beginning of 2024. I aim to give insight into the relationships between Crystals and humans but also the effects Crystals have on the users.

The milk production per cow has increased considerably during the last 50 years and due to the breeding for higher milk production also brings decreased reproduction efficiency. In a Swedish study 1996 it was shown that on average only half of all estruses were detected. Every time a farmer fails to detect oestrus it costs the farmer about 1200 Swedish crones and the need of means of detecting oestrus is therofore large. With this study we wanted to investigate if heart rate respectively crystallisation of vaginal mucus (arborisation) could be useful means of detecting oestrus. We monitored two oestrus cycles in four heifers.

Snö har en stor betydelse för oss inom hydrologin samt ekologin. Inom hydrologin har snön inverkan på våra vattendrag under vinter och vår dessutom har den en stor betydande roll för elektricitetsproduktionen via vattenkraft. För ekologin ger snön isolering för växter, marken och skydd för mindre djur arter. Snöförhållanden förklarar också ofta naturkatastrofer, så som lavinrisker och översvämningar i vattendragen. Ökad kunskap om snöegenskaper skulle kunna hjälpa oss att förstå alla ovan nämnda skeenden bättre.På Abiskos naturvetenskapliga forskningsstation har det sedan år 1961 till nu gjorts snöprofilsmätningar, där snötäckets egenskaper, tjocklek, snölagrets täthet/hårdhet, snö kristallernas fasthet, snökornens storlek och snöns torrhet uppskattas.

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.
