This paper reports a comparison of soft and hard piezoceramic transducer materials used for ultrasonic particle trapping in a microfluidic bioanalytical platform. The investigation is made with the objective to obtain high acoustic forces with a minimum of temperature increase. Themperature is a critical parameter for bioassays and most often need to be kept below a certain level to allow handling
Popular Abstract in Swedish Azofärger är syntetiska kemikalier som används i stor utsträckning för att färga konsumtionsartiklar, t.ex. läder, textiler, mat, kosmetika. Dock kan ett fåtal av dessa färger reduktivt avspjälkas och till följd därav frigöra kancerogena aromatiska aminer. Av den orsaken har EU infört ett förbud i medlemsstaterna mot användning av potentiellt farliga azofärger i läder- Dyes are commercially indispensable and the expanding industry offers a complete palette of colors. Azo dyes constitute the largest chemical class of synthetic dyes because of their versatility, low price, and ease of production. These dyes may, however, pose health risk to humans due to formation of mutagenic/carcinogenic aromatic amines upon reductive cleavage of their azo groups (-N=N-). Theref
In this paper, we analyse the prototypicality of the passive voice in the Slavic languages. We argue that there are some variations in the periphrastic passive, which stem from the historical development of the tense-aspect system, particularly from an earlier resultative construction in the case of Indo-European languages. The periphrastic construction in some languages has abandoned the earlier
A crucial debate is under way concerning the public's participation in biotechnology decision-making processes. This study, concerning the policy process around xenotransplantation (XTP) in Latvia and Sweden in the period 1970-2004, focuses on how scientific experts and politicians view the public and the public's participation in the process of developing policy regarding XTP. Drawing on intervie
This project was recently carried out as a part of The Swedish Pompeii Project, which was started in 2000 as a research and fieldwork activity initiated by the Swedish Institute in Rome. The aim was to record and analyze an entire Pompeian city block, Insula V 1. Since autumn 2011 a new branch of advanced digital archaeology, involving 3D reconstructions and documentation methods, was added to the
De arkeologiska fragmenten visar att det är möjligt att även längre till- baka i tiden skönja förhållningssätt till landskapet även om namn och his- toria är glömda. Många platser har försvunnit ur vårt minne och några har väckts till liv av arkeologerna. Vi vet att det finns massor av bortglömda platser kvar att upptäcka. Kullabygden kommer att vara ett eldorado också för framtida forskare. Somt
Abstract in UndeterminedEdge sealing is often used to assure one-dimensional moisture flow and a defined exposure area in moisture transport experiments. This paper deals with the performance of a number of edge sealing systems including wax-paraffin mix, epoxy adhesive, silicone and different tapes and films. The overall performance of the sealing systems includes vapor permeability and hygroscop
Swedish Red (SR) dairy cattle is the second most common breed in Sweden and hence SR milk quality is crucial for the nutritional value and the processability of the milk delivered to the Swedish dairies. This thesis will give an insight into the quality of milk from SR cows and it will illuminate the possibilities for improvements of both breeding programs and the quality of different dairy produc
A building-integrated multifunctional PV/T collector have been developed and evaluated. The PV/T solar window is constructed of PV cells laminated on solar absorbers and is placed in a window behind the glazing. To reduce the costs of the solar electricity, reflectors have been introduced in the construction to focus radiation onto the solar cells. The tiltable reflectors render a possibility to c
