Lunar synchronization of daily activity patterns in a crepuscular avian insectivore
Biological rhythms of nearly all animals on earth are synchronized with natural light and are aligned to day-and-night transitions. Here, we test the hypothesis that the lunar cycle affects the nocturnal flight activity of European Nightjars (Caprimulgus europaeus). We describe daily activity patterns of individuals from three different countries across a wide geographic area, during two discrete
A complete time-calibrated multi-gene phylogeny of the european butterflies
With the aim of supporting ecological analyses in butterflies, the third most species-rich superfamily of Lepidoptera, this paper presents the first time-calibrated phylogeny of all 496 extant butterfly species in Europe, including 18 very localised endemics for which no public DNA sequences had been available pre-viously. It is based on a concatenated alignment of the mitochondrial gene COI and u
Coulomb Excitation of Proton-rich N = 80 Isotones at HIE-ISOLDE
A projectile Coulomb-excitation experiment was performed at the radioactive ion beam facility HIE-ISOLDE at CERN. The radioactive 140Nd and 142Sm ions were post accelerated to the energy of 4.62 MeV/A and impinged on a 1.45 mg/cm2-thin 208Pb target. The γ rays depopulating the Coulomb-excited states were recorded by the HPGe-array MINIBALL. The scattered charged particles were detected by a double
3D-Printed Soft Lithography for Complex Compartmentalized Microfluidic Neural Devices
Compartmentalized microfluidic platforms are an invaluable tool in neuroscience research. However, harnessing the full potential of this technology remains hindered by the lack of a simple fabrication approach for the creation of intricate device architectures with high-aspect ratio features. Here, a hybrid additive manufacturing approach is presented for the fabrication of open-well compartmental
Favorable Propagation with User Cluster Sharing
We examine the favorable propagation (FP) behavior of a massive multi-user multiple-input-multiple-output (MU-MIMO) system equipped with a uniform linear array (ULA), horizontal uniform rectangular array (HURA) or uniform circular array (UCA) using a ray-based channel model with user cluster sharing. We demonstrate FP for these systems and provide analytical expressions for the mean-squared distan
Hydrophobic and Hydrophilic Extractives in Norway Spruce and Kurile Larch and Their Role in Brown-Rot Degradation
Extractives found in the heartwood of a moderately durable conifer (Larix gmelinii var. japonica) were compared with those found in a non-durable one (Picea abies). We identified and quantified heartwood extractives by extraction with solvents of different polarities and gas chromatography with mass spectral detection (GC-MS). Among the extracted compounds, there was a much higher amount of hydrop
Till det sociala arbetets försvar : - vad försvarar forskare och praktiker i socialt arbete?
Syftet med den här texten är att stå upp till det professionella sociala arbetets försvar genom ett kritiskt förhållningssätt till både forskare och socionomer/praktiker i socialt arbete. Vad gäller forskare riktas blicken framförallt mot forskarkarriären, och vad gäller socionomer uppmärksammas yrkesutövningen på den fältbaserade praktiken med fokus på kommunal aktivering av arbetslösa och brukar
Deadly violence in Sweden: Profiling offenders through a latent class analysis
BackgroundSweden has in recent years witnessed increasing rates of firearm-related violence and homicide, which has contributed to increased rates of deadly violence. Attempts to profile offenders committing such crimes are of major importance, because such efforts may contribute to better preventive measures. We therefore aimed to study the characteristics of individuals convicted and/or suspecte

Tolkning av entreprenadavtal
I Tolkning av entreprenadavtal behandlas praktiskt återkommande tolkningsfrågor som aktualiserar tolkning av villkor i andra kontraktshandlingar än Allmänna bestämmelser. Detta sker mot bakgrund av såväl Högsta domstolens praxis som avgöranden från underrätterna. Boken riktar sig till praktiskt verksamma jurister samt ingenjörer och andra yrkesgrupper som regelbundet arbetar med entreprenadavtal.
Strategic improvisation in crisis communication
Falkheimer and Heide further develop their integration of improvisation into crisis communication. They argue that improvisation is a way to develop innovative thinking. Falkheimer and Heide argue crisis managers must adapt to new circumstances and situations making improvisation a value asset. Drawing from the leadership literature, they develop the idea of strategic improvisation. Strategic impr
The Impact of Parental Diabetes on the Prevalence of Childhood Obesity
Background: Obesity among children and adolescents is a worldwide public health concern. Type 1 diabetes (T1D) and type 2 diabetes (T2D) incidence are increasing, with heredity and socioeconomic status as possible risk factors. How these factors affect the risk of childhood obesity remains unclear. The aim of this study was to investigate the association between obesity and parental diabetes among
On COVID 19 and commercial surrogacy in Ukraine
Surrogacy has been a legal practice in Ukraine since 2000. Being a cheaper option (surrogacy in Ukraine costs around USD 50.000 compared to USD 100.000 in the USA), Ukraine became an even hotter spot after other popular destinations, such as India, Nepal, and Thailand, banned compensated surrogacy for foreigners. Moreover, this is not only the price tag that made Ukraine such an appealing option.

Regulation of IRS-1, insulin signaling and glucose uptake by miR-143/145 in vascular smooth muscle cells
Regulation of insulin signaling by microRNAs in smooth muscle cells may contribute to diabetic vascular disease. The two smooth muscle enriched miRNAs miR-143 and miR-145 have been reported to target mediators of insulin signaling in non-smooth muscle cells. In this study, we aimed to determine the importance of this regulation in vascular smooth muscle cells, where expression of miR-143/145 is mu
Feature size control using surface reconstruction temperature in block copolymer lithography for InAs nanowire growth
Here we present a method to control the size of the openings in hexagonally organized BCP thin films of poly(styrene)-block-poly(4-vinylpyridine) (PS-b-P4VP) by using surface reconstruction. The surface reconstruction is based on selective swelling of the P4VP block in ethanol, and its extraction to the surface of the film, resulting in pores upon drying. We found that the BCP pore diameter increa
