Variability of Christmas rose (Helleborus niger L.) populations and its potential use in genetic breeding

2005

International audience; The Christmas rose (Helleborus niger L.) is widely distributed in Southern and Central Europe, and Slovenia is probably one of the centers of its diversity. The investigation was aimed at evaluating phenotypic diversity among selected wild populations in Slovenia and neighboring Croatia. Some of the analyzed traits expressed relatively very high variation (e.g., number of leaves per plant, number of inflorescences per plant). The variation ranges of some of the analyzed traits were found to be wider than those mentioned in the literature. Statistical analysis indicated that variability was more expressed within than between populations. In terms of present market req…

"Dis poem is still not written." A Study of Diamesic Variation in Jamaican Dub Poetry

2020

International audience; This paper looks at diamesic variation in the works of Jamaican and Anglo-Jamaican dub poets such as Linton Kwesi Johnson, Benjamin Zephaniah and Mutabaruka. Dub poetry constitutes a turning point in the history of literature in Creole, since the genre achieved to establish Patwa as the legitimate medium for Caribbean writers, thereby effectively inverting (post)colonial linguistic hierarchies. Though closely associated with the reggae tradition, dub poets have always claimed to be doing “real” literature and published their work in written form as well as in audio or video recordings. The paper analyses various strategies to inscribe orality and orature in written t…

Quantitative determination of casein genetic variants in goat milk: Application in Girgentana dairy goat breed

2016

The study was conducted to develop a high-performance liquid chromatographic (HPLC) method to quantify casein genetic variants (αs2-, β-, and κ-casein) in milk of homozygous individuals of Girgentana goat breed. For calibration experiments, pure genetic variants were extracted from individual milk samples of animals with known genotypes. The described HPLC approach was precise, accurate and highly suitable for quantification of goat casein genetic variants of homozygous individuals. The amount of each casein per allele was: αs2-casein A = 2.9 ± 0.8 g/L and F = 1.8 ± 0.4 g/L; β-casein C = 3.0 ± 0.8 g/L and C1 = 2.0 ± 0.7 g/L and κ-casein A = 1.6 ± 0.3 g/L and B = 1.1 ± 0.2 g/L. A good correl…

Values and subjective well-being

2018

Research on relations of personal values to subjective well-being has begun to flourish only recently. This is surprising because our values represent what we consider important and worth pursuing in life, and our subjective well-being (henceforth SWB) represents how happy and satisfied we are with the life we are leading. This chapter summarizes what we know about value—SWB relations and identifies some of what we do not know but would like to know. We first discuss the nature of values and the structured system they form. We then note three theoretical perspectives on relations of values to SWB (Sagiv & Schwartz, 2000; Sagiv, Roccas & Hazan, 2004). The first perspective seeks to explain d…

Distinct bhaplotype structure at the innate immune receptor Toll-like receptor 2 across bank vole populations and lineages in Europe

2015

Abstract: Parasite-mediated selection may contribute to the maintenance of genetic variation at host immune genes over long time scales. To date, the best evidence for the long-term maintenance of immunogenetic variation in natural populations comes from studies on the major histocompatibility complex (MHC) genes, whereas evidence for such processes from other immune genes remains scarce. In the present study, we show that, despite pronounced population differentiation and the occurrence of numerous private alleles within populations, the innate immune gene Toll-like receptor 2 (TLR2) displays a distinct haplotype structure in 21 bank vole (Myodes glareolus) populations across Europe. Haplo…

Physical Activity Levels in Preschool Children During Winter and Summer

2019

Source at https://fysioterapeuten.no/Tidsskrifter. Bakgrunn: Studier nasjonalt og internasjonalt indikerer at barn i alderen tre til fem år ikke oppnår retningslinjene for anbefalingene (2014) om minimum 60 minutter med moderat til høy fysisk aktivitet (MVPA) per dag. Studiens hovedmål var å undersøke fysisk aktivitetsnivå hos barnehagebarn i tre barnehager i alderen tre til fem år i en periode om vinteren og en periode om våren/sommeren. Metode: Fysisk aktivitet ble målt i barnehagetiden fra mandag til onsdag med aktivitetsmåleren Actigraph GT3X. Aktivitetsnivået ble kategorisert ut fra antall akselerometer- tellinger/min, hvor hovedvariabelen var tid i moderat til høy fysisk aktivitet (MV…

A quantitative assessment of intraspecific morphological variation in Gahagan bifaces from the southern Caddo area and central Texas

2019

This investigation aggregates intact or reconstructed Gahagan bifaces from the southern Caddo area and central Texas to test the hypothesis that Gahagan biface morphology differs between the regions. The Gahagan bifaces (n = 102) were scanned, then analysed using a novel landmarking protocol and the tools of geometric morphometrics. Results provide a preview of the significant differences in Gahagan biface morphology expressed between the southern Caddo area and central Texas regions. The size discrepancy represents an inversion of current theoretical constructs that posit a decrease in tool size thought to articulate with an increase in distance from the raw material source. It is posited …
