Challenges and best practices for deriving temperature data from an uncalibrated UAV thermal infrared camera

Miniaturized thermal infrared (TIR) cameras that measure surface temperature are increasingly available for use with unmanned aerial vehicles (UAVs). However, deriving accurate temperature data from these cameras is non-trivialsince they are highly sensitive to changes in their internal temperature and low-cost models are often not radiometrically calibrated. We present the results of laboratory a

Realization of Wurtzite GaSb Using InAs Nanowire Templates

The crystal structure of a material has a large impact on the electronic and material properties such as band alignment, bandgap energy, and surface energies. Au-seeded III–V nanowires are promising structures for exploring these effects, since for most III–V materials they readily grow in either wurtzite or zinc blende crystal structure. In III–Sb nanowires however, wurtzite crystal structure gro

The potential for active commuting by bicycle and its possible effects on public health

IntroductionThe World Health Organization (WHO) has concluded that physical inactivity and overweight/obesity are the world's fourth and fifth leading risk factors for non-communicable diseases, respectively. This article investigates the potential for active commuting by bicycle in Scania county, southern Sweden, and its possible impact on public health. Physical inactivity is a growing problem o

Sustainable Welfare beyond Growth

A deprioritization of economic growth in policy making in developed nations will need to be part of a global effort to tackle climate change and reembed economy and society into planetary boundaries. The presentation introduces the concept of 'sustainable welfare', which integrates environmental sustainability and social welfare research. Central to this concept is the notion of human needs and ho

Neutron spectroscopy on protein solutions employing backscattering with an increased energy range

Novel cold neutron backscattering spectrometers contribute substantially to the understanding of the diffusive dynamics of proteins in dense aqueous suspensions. Such suspensions are fundamentally interesting for instance in terms of the so-called macromolecular crowding, protein cluster formation, gelation, and self-assembly. Notably, backscattering spectrometers with the highest flux can simulta

Pirates in Suits: Carl Schmitt, ‘Ordinary Businessmen’ and Crimes of Aggression

The article critically appraises Carl Schmitt’s 1945 expert opinion on The International Crime of the War of Aggression and the Principle ‘nullum crimen, nulla poena sine lege’. Each element of Carl Schmitt’s expert opinion is subjected to close scrutiny and contextualised with references, where appropriate, to the icc’s recently acquired jurisdiction to try crimes of aggression. It is shown that

Legitimized Refugees : A Critical Investigation of Legitimacy Claims within the Precedents of Swedish Asylum Law

This study focuses on asylum cases decided at Sweden’s migration courts. More precisely, it analyses how the highest legal instance, the Migration Court of Appeal (hereafter MCA), legitimizes decisions that concern asylum seekers. Using critical discourse analysis (CDA), the study makes power relations visible. Investigating central discursive claims that are expressed in the precedents of Swedish

Uric acid detection by means of SERS spectroscopy on dried Ag colloidal drops

Uric acid concentration in human bodily fluids is an important marker for disorders such as gout, pre‐eclamsia or cardiovascular disease. However, currently used methods for its detection either lack sensitivity or require sophisticated, bulky and expensive equipment. In this work, we show that by using surface‐enhanced Raman scattering spectroscopy (SERS) on dried Ag colloidal drops and with 1064

Eosinophils in anti-neutrophil cytoplasmic antibody associated vasculitis

Background: Anti-neutrophil cytoplasmic antibodies associated vasculitides (AAV) are characterized by autoimmune small vessel inflammation. Eosinophils are multifunctional cells with both pro-inflammatory and immunoregulatory properties. Tissue activated eosinophils secrete cyto- and chemokines and form extracellular traps (EETs), they release free granules and produce reactive oxygen species. The

Quinoa Stalks Glucuronoarabinoxylan : Biorefinery,xylooligosaccharides production and potential applications

Quinoa stalks were used as a source of hemicellulose for XOs production and further as prebiotic source for probiotic bacteria. Three methods for extraction of hemicellulose were used, of which alkaline extraction (NaOH [0.5 M]) was the optimum method. This methodology allowed the establishment of a sequential extraction platform, including saponins obtention via PHWE, hemicellulose via alkaline e

Morphometric analyses and species delimitation in Legousia (Campanulaceae)

In order to evaluate the traditional morphological characters commonly used to distinguish the taxonomically problematic species of Legousia, we carried out a morphometric study with univariate analysis, principal component analysis (PCA), discriminant analysis (DA) and cluster analysis (UPGMA). The analyses were based on data from 436 individuals on 207 herbarium specimens from 18 countries in EuIn order to evaluate the traditional morphological characters commonly used to distinguish the taxonomically problematic species of Legousia, we carried out a morphometric study with univariate analysis, principal component analysis (PCA), discriminant analysis (DA) and cluster analysis (UPGMA).

Synthesis of polypyrrole microspheres by Streptomyces spp.

The present paper shows a green method for the formation of polypyrrole by two different MIUG 12p and MIUG 4.88 strains of Streptomyces spp. bacteria. According to our knowledge, such method has never been proposed before for pyrrole oxidation. For this experiment pyrrole monomer was added into bacterial medium after 6 days of incubation and after 4 days polypyrrole (PPy) based 10–25 μm microspher

Controllable formation of high density SERS-active silver nanoprism layers on hybrid silica-APTES coatings

In this work sol-gel process for preparation of the uniform hybrid silica-3-aminopropyltriethoxysilane (APTES) coatings on glass surface is presented from mechanistic point of view. The suggested synthetic approach is straightforward, scalable and provides the means to tune the amount of amino groups on the surface simply by changing concentration of APTES in the initial sol. Deposition rate of di

Structural Studies of 1,1-Dimethyl-2-oxy-1-silacyclohexane by Means of Matrix Isolation Infrared Absorption Spectroscopy

Infrared spectra of gaseous, liquid, and matrix-isolated samples of newly synthesized 1,1-dimethyl-2-oxy-1-silacyclohexane were recorded. Raman spectra of 1,1-dimethyl-2-oxy-1-silacyclohexane in liquid and solid states were obtained in the temperature range from 170 to 340 K. Ab initio HF and DFT B3LYP calculations were performed in order to determine the possible conformations of 1,1-dimethyl-2-o

Raman and infrared spectroscopic studies of structure and stability of 1,1,2,2-tetrachloro-1,3-disilacyclopentane

Raman spectra of liquid, and infrared spectra of gaseous as well as matrix isolated 1,1,2,2-tetrachloro-1,3-disilacyclopentane were recorded and analyzed with the aid of DFT calculations. Complete assignment of the experimental vibrational spectral bands is made. Experimental results and DFT calculations confirm that 1,1,2,2-tetrachloro-1,3-disilacyclopentane exists as single twist conformer in ga
