The goal of this study is to investigate the applicability of asymmetrical flow field-flow fractionation (AsFlFFF)–multi angle laser light scattering (MALLS), and to develop a method for analysis of cationic potato amylopectin (CPAP) having ultrahigh molecular mass (UHMr). Use of the aqueous carrier having low salt content (3 mM NaN3) resulted in a distortion in AsFlFFF fractograms of CPAP with a
3AbstractThis study primarily aims at identifying whether the Swedish excise tax on certain electronic products have had an effect regarding the chemical content of such products since its implementation in mid-2017. The tax is meant to reduce the presence of dangerous flame retardants in the affected products, that otherwise risk harming the public or the environment. Potential negative effects o

Regulation of development and entry into sporulation is critical for fungi to ensure survival of unfavorable environmental conditions. Here we present an analysis of gene sets regulating sporulation in the homothallic ascomycete Ashbya gossypii. Deletion of components of the conserved pheromone/starvation MAP kinase cascades, e.g., STE11 and STE7, results in increased sporulation. In kar3 mutants
The study investigates explicit and implicit knowledge of article semantics in 26 second language learners of English. Their first languages, Russian and Belarusian, lack articles. The research question is whether explicit knowledge, operationalised as an ability to explain what principle governs the choice between the definite and the indefinite article in a multiple-choice test, is associated wi
The town of Blera is situated in the southern parts of Etruria and has a history spanning more than 2,500 years. Its location between the two important Etruscan cities of Tarquinii and Caere has meant that Blera, for the entire Etruscan period (c. 750–50 BC), alternatively has found itself in either city’s sphere of interest. When Rome begins her expansion into Etruria, following the fall of the s
The random k-SAT model is one of the most important and well-studied distributions over k-SAT instances. It is closely connected to statistical physics and is a benchmark for satisfiability algorithms. We show that when k=Θ(log n) , any Cutting Planes refutation for random k-SAT requires exponential length in the regime where the number of clauses guarantees that the formula is unsatisfiable with
Background: There are no data showing that disperse dyes, used to patch test patients, are currently being used for dyeing synthetic garments. It is unknown whether disperse dyes, which are currently routinely patch tested, are in fact present in synthetic textiles on the market. Objectives: To determine whether eight disperse dyes, hitherto most widely cited as allergenic, are still used in tex
In this paper, I evaluate the usefulness of protein homology models in rigorous free-energy simulations to determine ligand affinities. Two templates were used to create models of the factor Xa protein and one template was used for dihydrofolate reductase from Plasmodium falciparum. Then, the relative free energies for several pairs of ligands were estimated using thermodynamic integration with th
The media often cast foreign private equity firms as villains who gamble with local jobs. We use detailed registry data from Sweden to show that foreign buyouts have not affected workers’ labor market outcomes. But domestic buyouts have. They have increased unemployment incidence by a fifth, duration by a third, and lowered labor income by seven percent.
