BACKGROUND: The aim of the study was to evaluate how well vascular function is retained in a cadaver kept in a room with a temperature of 21 degrees C. METHODS: The aorta and pulmonary artery of rats were investigated in organ baths as fresh controls and after 1, 2, 3, or 6 hours' storage in the cadaver. Six-hour-old cadaver aortas were transplanted and investigated after 24 hours and 60 days. RES
During memory formation, structural rearrangements of dendritic spines provide a mean to durably modulate synaptic connectivity within neuronal networks. New neurons generated throughout the adult life in the dentate gyrus of the hippocampus contribute to learning and memory. As these neurons become incorporated into the network, they generate huge numbers of new connections that modify hippocampa
G.Fast is a new standard for fixed broadband access that aims at achieving bit rates of 1 Gb/s over short copper loops. In order to give support to simulation, design and performance evaluation tests, the G.Fast recommendation presents examples of some wiring topologies and reference loops describing configurations expected to be found in real G.Fast deployments. Our work describes results of mode
We have experimentally studied the conditions for acoustic particle focusing inside aqueous droplets in two-phase-systems, and confirmed our findings by theoretical analysis. The results show that the acoustic properties of the two fluids have to be matched to achieve strong acoustic resonance and focusing in the system.
This abstract reports a novel acoustofluidic method to measure the hematocrit level of a whole blood sample within 20 seconds. The method is substantially faster than conventional centrifugation methods, has no moving parts and can be fully automated and integrated with further unit operations for analysis of blood samples at the point of care [1].
I juli 2016 introducerades lagen om tillfälliga begränsningar av möjligheten att få uppehållstillstånd i Sverige (den tillfälliga lagen). Ikraftträdandet av den tillfälliga lagen innebar att rätten till familjeåterförening för alternativt skyddsbehövande begränsades avsevärt. Enligt 7§ den tillfälliga lagen exkluderades alternativt skyddsbehövande från rätten att återförenas med sin familj under dIn July 2016, the Law on temporary limitations to the possibility of being granted residence permit in Sweden (the Temporary Law) came into force. The Temporary Law implied a sharp turn in Swedish asylum legislation. The right to family reunification, which previously had been granted subsidiary protection beneficiaries and refugees on a similar basis, was suddenly heavily restricted for beneficia
Segregation är ett föränderligt tillstånd som är komplext och påverkar såväl enskilda individer som samhället i stort. Exempelvis är stadsplaneringen en bakomliggande orsak som kan påverkar segregationen i en stad. För att det verkligen ska kunna ske en förbättring är det emellertid av stor vikt att åtgärder vidtas på olika plan och av olika aktörer. Det ursprungliga syftet bakom arbete är att utSegregation is a changing condition that is complex and affects individuals but also the society. Urban planning is for example an underlying cause that can affect segregation in a city. However, in order for an improvement, it is of great importance that measures are taken at different levels and by different actors. The primary purpose of the report was to study the impact that urban planning h
Exploring a prolonged life cycle of materials through an adaptive transformation Take, make and waste. Our society is trapped in a linear economic system where we extract raw materials, process them into products and as they have served their purpose they are reduced to waste. This unsustainable mentality seeps through to all things consumable, from fashion and cellphones to kitchen counters and
This thesis presents the development of a prototype for a concealed power strip integrated into the underside of a sofa. The aim is to improve accessibility to electrical outlets while maintaining a clean and unobtrusive appearance in the living environment. The solution is designed to both hide cables and allow convenient access to power when seated, while ensuring sufficient ground clearance for
An acoustofluidic device, consisting of a polymer chip with a long straight channel, coupled to a piezoelectric transducer is modeled numerically in three dimensions and compared to experimental results in terms of the electric admittance as well as the ability to focus particles. In our experiments we obtain good acoustic particle focusing at a frequency of f = 1.14 MHz with an actuation voltage
Institutional economics has produced a string of findings about the importance of good institutions for economic growth and development. While consensus is lacking about how important institutions are, few scholars argue that institutions have no impact whatsoever. Yet, for all the knowledge produced, the results of institutional reforms are meager. This is not surprising as a central theme in the
Applying optimal control to photoinduced trans-cis isomerization in condensed phase, the dynamics of bond-twisting motion of 1,1'-diethyl-4,4'-cyanine in methanol and propanol is revealed. The shape of the optimized pulse resulting from minimization of the photoisomer formation can be directly related to the initial excited-state dynamics in close proximity to the Franck-Condon point. The solvent

Acquiring Germanic verb second is typically described as difficult for second-language learners. Even speakers of a V2-language (Swedish) learning another V2-language (German) are said not to transfer V2 but to start with a non-V2 grammar, following a universal developmental path of verb placement. The present study contests this claim, documenting early targetlike V2 production for 6 Swedish ab-i
The aging of us humans is individual and occurs gradually over a long period of time. Some functions in the body deteriorate and older people often have difficulty for various reasons to get the amount of nutrition they need, so they usually need to divide their diet into more meals distributed during the day. In this essay, the diet served in a retirement home in a small municipality in northwest
