W artykule przedstawiono, jaki stosunek do norm grzecznościowych prezentują korektorzy i redaktorzy językowi konwersujący ze sobą w zawodowej grupie dyskusyjnej (najbardziej reprezentatywnej spośród grup skupiających redaktorów korektorów) na portalu społecznościowym Facebook. Badany materiał pochodzi przede wszystkim z kwietnia maja 2021 r. obejmuje zwroty adresatywne oraz formuły powitalne — ...

Families of repeated sequences are present in the genomes of all eukaryotes. Little is known about the mechanism(s) that prevents recombination between repeated sequences. In the yeast Saccharomyces cerevisiae, recombination between homologous sequences placed at nonhomologous locations in the genome (ectopic recombination) has been shown to occur at high frequencies for artificially created re...

BACKGROUND Transgender and gender nonconforming people experience some of the highest human immunodeficiency virus (HIV) rates in the United States, and experience many structural and behavioral barriers that may limit their engagement in HIV testing, prevention, and care. Evidence suggests that transgender and gender nonconforming youth (TY) are especially vulnerable to acquiring HIV, yet ther...

Tyrosinase was the first melanoma-associated antigen shown to be recognized by CD4+ T cells. In this study, we have identified two HLA-DRB1*0401-restricted peptides recognized by these T cells: Ty 56-70 and Ty 448-462. As with many of the MHC class I-restricted melanoma epitopes, both are nonmutated self peptides that have intermediate and weak MHC binding affinities, respectively. Mutated and ...

Fourteen 8-week-old calves infected with S. typbimurium were fed control and 10 mg/ head/day bambermycins in an 8-week study to determine the effect on quanti ty, prevalence, shedding and susceptibi l i ty of Salmonella. Special precautions were taken to eliminate crosscontaminat ion between infected and uninfected animals on both treatments. Salmonella counts of the homogenized fecal samples w...

Sphingosine 1-phosphate (S1P) induces diverse biological responses in various tissues by activating specific G protein-coupled receptors (S1P(1)-S1P(5) receptors). The biological signaling regulated by S1P(3) receptor has not been fully elucidated because of the lack of an S1P(3) receptor-specific antagonist or agonist. We developed a novel S1P(3) receptor antagonist, 1-(4-chlorophenylhydrazono...

A scheme for explicit ly representing and using expert knowledge of a procedural k ind is described. The scheme al­ lows the explicit representation of both declarative and proce­ dural knowledge wi th in a unified framework, yet retains all the desirable properties of expert systems such as modular i ty , ex­ planatory capabil i ty, and extendabil i ty. It thus bridges the gap between the proc...

Let C be a closed convex subset of a complete metrizable topological vector space (X ,d) and T : C → C a mapping that satisfies d(Tx,Ty) ≤ ad(x, y) + bd(x,Tx) + cd(y,Ty) + ed(y,Tx) + f d(x,Ty) for all x, y ∈ C, where 0 < a < 1, b ≥ 0, c ≥ 0, e ≥ 0, f ≥ 0, and a+ b + c + e + f = 1. Then T has a unique fixed point. The above theorem, which is a generalization and an extension of the results of se...

Recently P. R. Halmos [S] mentioned a question raised by S. V. Fomin as to whether it follows that two measure preserving transformations are conjugate if they are unitarily equivalent and possess the same entropy. The purpose of this work is to concoct a counterexample to this conjecture. Let X be the unit interval with Borel measurability and Lebesgue measure. Let XXX be the unit square and X...

BACKGROUND To explore if health related quality of life(HRQoL) increased after traditional yoga(TY), mindfulness based cognitive therapy(MBCT), or cognitive behavioral therapy(CBT), in patients on sick leave because of burnout. METHODS Randomized controlled trial, blinded, in ninety-four primary health care patients, block randomized to TY, MBCT or CBT (active control) between September 2007 ...
