Popular Abstract in Swedish Bakgrund Många känner idag till att det är viktigt att gamla läkemedel lämnas in till apoteken för att de inte ska hamna i naturen. Det som man oftast inte känner till är att även de läkemedel som vi konsumerar riskerar att tillslut hamna i naturen. Eftersom svenska reningsverk bara tar bort en bråkdel av läkemedelsresterna i vår urin. Det här leder till att man vid utlPharmaceuticals are today released into aquatic environments where they can interfere with organisms' biological processes.The general research objective was to analyze how aquatic freshwater organisms are affected by exposure to pharmaceuticals that are categorized by the EU as potential risk factors to the environment (i.e., 17α-Ethinylestradiol (EE2) and diclofenac). The main aim of this thesis

Popular Abstract in Undetermined The transparent wings of tiny parasitic wasps and small flies are remarkably thin, only a few hundreds nanometers thick, and may appear to have a simple structural airfoil design. The thesis deals with new findings about structural color reflections and the ultrastructure of such tiny transparent wings of parasitic wasps. The main discovery is that when seemingly tThe remarkably thin transparent wing membranes in tiny wasps may appear to have a simple structural design, but hide a largely unexplored complex of micro-morphological features that serve aerodynamics and may also function in visual signaling. I found that when such small transparent wings are viewed against a dark background they display vivid structural color patterns due to thin film interfere

Many courses within higher education are assessed by “faculty standards” sometimes based on the implicit assumption that “it has always been like this, therefore it is the best”. Selecting and combining different assessment modes in an effective manner for a particular course are central issues. The process does not always entail a simple and straight-forward decision making. The main purpose of t

Tillsammans med en artikel om P. Waldenström speglar denna artikel spänningarna i svensk kristenhet under slutet av 1800-talet. Sundberg har kallats ”den mest självsäkre, frispråkige och myndige kyrkofursten på den svenska ärkebiskopsstolen sedan medeltiden”, men han kämpade med svåra depressioner. Sitt praktiska sinne använde han både som redaktör för Swensk Kyrkotidning och i Svenska Akademien.

The word “desertification” was introduced in 1949 by the French scientist Aubreville in his report “Climats, forêts et désertification de l´Afrique tropicale”. The concept, however, was discussed earlier by European and American scientists in terms of increased sand movements, desiccation, desert and Sahara encroachment and man made deserts. Desertification, at the beginning of last century, mea

We present first results of fluxes of biogenic VOC emitted from the vegetation at a sub-arctic wetland in northern Sweden, measured using the disjunct eddy covariance (DEC) technique with a Proton Transfer Reaction-Mass Spectrometer (PTR-MS) as scalar sensor.

The purpose of this study is to dissect the process of ideological orientation in the public debate of postwar Sweden. Crucial to the study is the idea of a generic totalitarianism; a concept used both on a scholarly and a political level, focusing on the similarities between communism and Nazism, and the diverging guiding potential of this totalitarianism idea in different times and situations.

Proton exchange membrane fuel cell (PEMFC) systems have been investigated as alternative power sources for the stationary and automotive applications. However, they do not appear on the market yet. One of the main reasons is the difficulty of the water/thermal management in the system. Several water recovery schemes have been proposed to overcome this difficulty and to simplify the system configur
