I alla tider och på alla platser har människan försökt förstå hur världen hänger ihop. Sökandet efter den substans som bygger världen har lett oss till upptäckterna av molekylerna, atomerna och atomernas byggstenar. Och när man tränger längre och längre in i materiens märkligheter finner man att svaren inte bara ligger i vad byggstenarna är, utan också hur de trivs med varandra. Växelverkan – hur

This essay is about drinking cups in the symposion setting on painted ceramic. The goal of this essay is to study different kinds of cups and how they were used. I found two main kinds of cups kylix and skyphoi. The kylix was more represented then the skyphoi. I also found that kottabos was one of the most represented motive. And I also focus on difference of black and red figure vases. The method

In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. Elevated CO2 has been shown to not only increase photosynthetic rates in

Taphonomy is the study of how different processes have affected the osteological material, from the death of the animal and forward. The purpose of the analysis is to study how taphonomic processes and fluvial activity affect the preservation of osteological material in a wetland environment, by examining the zooarchaeological material from Röekillorna Spring (Löderup parish, Scania). A quantitati

This report starts by delivering a statement of its purpose, namely, to explore and learn from the entire building process, through the construction of a small sauna on a raft. It begins with a brief inventory of bathing culture and its history throughout the world before arriving at the Finnish sauna and the bathing culture of the Swedish west coast. The project and its concept is then introduced

This article discusses the interweaving of queerness, affect and translation in the asylum process, focusing on the role of legal representatives. Through 16 semi-structured interviews with asylum lawyers in Greece, it explores their collaborative work with queer asylum seekers in preparing a “credible” account. Approaching legal preparation as a process of translating applicants’ emotions into wh

Miljöfrågan är högaktuell i dagens samhälle. Företagen och kommunerna tävlar om att vara mest klimatvänliga. Detta leder till en nyfikenhet kring hur byggnadsmaterial kan användas på ett mer effektivt sätt och hur de material som redans används i våra byggnader kan få ett nytt liv på bästa sätt. En stor andel av det som byggdes på 60-talet i Sverige var av tegel, därav har intresset för att kunna Environmental issues are highly topical in today´s society, with companies and municipalities competing to be the most climate friendly. This has sparked an increasing interest in how building material can be used more efficiently and how existing materials within buildings can be given a new life. A large proportion of buildings constructed in Sweden during the 1960s were made of brick, which has

The development of a forest stand in south-eastern Norway during the last 9000 years is investigated by pollen and charcoal analyses. The aims are to identify factors that have influenced current biodiversity, which includes the lichen Usnea longissima, and examine the immigration and establishment of the current dominant tree Picea abies. Fire has been a variable but major disturbance factor at t

Using a crystalline embedding scheme it has recently become possible to study free-standing III - V nanowires with cross-sectional scanning tunnelling microscopy (XSTM). In the present paper we discuss how this novel method can be used for direct atomically resolved imaging of the interior of nanowires. We will focus in particular on two areas where this method provides unique possibilities. First

Hydrophobic interactions are highly selective, and differences in surface hydrophobicities between proteins can be used as an efficient handle to facilitate protein isolation. Aromatic amino acid residues are of particular importance for molecular recognition because they have a key role in several biological functions. The hydrophobicity of a protein can easily be altered with minor genetic modif

A detailed analysis of the mobilizable, ColE1-like resistance plasmid, pUB2380, is reported. The 8.5-kb genome encodes six (possibly seven) major functions: (1) a ColD-like origin of replication, oriV, with associated replication functions, RNAI and RNAII; (2) a set of active mobilization functions highly homologous to that of ColE1, including the origin of transfer, oriT; (3) a ColE1-like multime

Non-radiative decay of core excitations at the B 1s and N 1s absorption edges of bulk hexagonal boron nitride (h-BN) has been studied with resonant Auger spectroscopy. In order to reproduce the bulk properties of the sample while keeping it electrically conducting, we have grown reasonably thick (more than 20nm) polycrystalline films of h-BN on a Ni(111) surface by thermal cracking of borazine vap
