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…
Determination Aspects of Possible Purchasing Prices for Blue Mussel Products from the Baltic Sea
2019
Demand for marine products has been relatively high and is increasing in most of countries. With higher demand for higher-value and protein-rich products population is looking for other sources that could be protein-rich products and might be substitute for fish products. Blue mussel contains proteins and minerals therefore it might become as food and feed ingredient and supplement product for food. Experience in many countries world-wide where mussel production is more developed has indicated that important aspect in realisation of the production is effective marketing. The following research methods were used in the research: studies of scientific publications on blue mussel price and fac…
A Revised Sex Assessment of the Epigravettian Human Remain ST1 from San Teodoro Cave (Messina, Sicily)
2013
Bias in skeletal sexing is well known and depends upon the completeness of the skeletal remains. The problem is very hard concerning prehistorical remains. We applied ‘Visual methods’ and ‘Probabilistic Sex Diagnosis’ (DSP) on the coxal bones on the Epigravettian skeleton (ST1) from San Teodoro (Messina, Sicily). On the basis of cranial characters and the overall robustness of the postcranial skeleton, it was suggested, since the time of the discovery, a male sex for ST1. This determination was later modified on the basis of the pelvic girdle morphology, and the skeleton was attributed the female sex for many years by large consensus. Our results indicate without ambiguity that ST1 is a mal…
Comportamiento de las correlaciones producto-momento y tetracórica-policórica en escalas ordinales: un estudio de simulación
2017
El análisis estadístico multivariante de escalas de respuesta tipo Likert, dado su empleo generalizado, resulta un tema controvertido en la comunidad científica, principalmente desde la especificación del problema de la medida. Este trabajo tiene como objeto estudiar cómo afectan diversas condiciones de estas escalas ordinales al cálculo de los coeficientes de correlación producto-momento y tetracórico-policórico. Para ello, se aplica un estudio de simulación en el que se generaron 90 bases de datos con 10 ítems cada una, controlando las siguientes variables: número de categorías de respuesta, distribución simétrica o asimétrica de los datos, tamaño de la muestra y nivel de relación entre l…
A metal-responsive interdigitated bilayer for selective quantification of mercury( ii ) traces by surface plasmon resonance
2016
Reusable surface plasmon resonance chips allowing the quantitative and selective detection of mercury(II) ions in water at the 0.01 nM level are reported. The surface-modified gold sensor consists of a rarefied self-assembled monolayer of octanethiol topped with a Langmuir–Blodgett monolayer of an amphiphilic and highly-specific chelator. The interdigitated architecture confers to the bilayer a high packing density, surface coverage, and binding-group accessibility.
Attitudes toward and motivation for PE: who collects the benefits of the subject?
2014
Background and purpose: Due to attitudinal and motivational aims in the national curriculum, and to lack of research on adolescents' experiences with physical education (PE) in Norway, the purposes of this study were to (1) attain data on attitudes toward PE and self-determined motivation for PE among a representative sample of adolescents (N = 2010) in middle school (grade 8–10/age 13–15) and high school (grade 11–13/age 16–19) in Norway, and (2) to explore the relationship between involvement in movement activities outside school and self-determined motivation in PE. Findings: The results showed that 43% of the adolescents were not happy with how PE is taught in Norwegian schools, and tha…

2021
Présentation d'une approche scientifique du phénomène d’auto handicap que l’on trouve chez certains élèves. Les auteurs nous proposent des réponses possibles face à ces stratégies. Cet article issu de la recherche apporte un réel éclairage scientifique sur un phénomène vécu au quotidien par les enseignants d’EPS et certains de leurs élèves.
Very high rotational frequencies and band termination in 73Br
2000
Rotational bands in 73Br have been investigated up to spins of 65/2 using the EUROBALL III spectrometer. One of the negative-parity bands displays the highest rotational frequency 1.85 MeV reported to date in nuclei with mass number greater than 25. At high frequencies, the experimental dynamic moment of inertia for all bands decrease to very low values, indicating a loss of collectivity. The bands are described in the configuration-dependent cranked Nilsson-Strutinsky model. The calculations indicate that one of the negative-parity bands is observed up to its terminating single-particle state at spin 63/2. This result establishes the first band termination case in the A = 70 mass region.
A global experiment on motivating social distancing during the COVID-19 pandemic
2022
Significance\ud \ud Communicating in ways that motivate engagement in social distancing remains a critical global public health priority during the COVID-19 pandemic. This study tested motivational qualities of messages about social distancing (those that promoted choice and agency vs. those that were forceful and shaming) in 25,718 people in 89 countries. The autonomy-supportive message decreased feelings of defying social distancing recommendations relative to the controlling message, and the controlling message increased controlled motivation, a less effective form of motivation, relative to no message. Message type did not impact intentions to socially distance, but people’s existing mo…
Purification by affinity chromatography of H1 RNA-Binding Proteins from rat brain
2003
Post-transcriptional regulation of mRNA metabolism is involved in processes as different as cell fate specification in development and cell response to a large variety of environmental cues. Regulation of all steps of RNA metabolism depends on RNA-binding proteins (RBPs). By using a T1 RNase protection assay, we previously identified three H1° RNA-binding factors (p40, p70 and p110), highly expressed in the rat brain. Here we report enrichment of these factors from brain extracts, obtained by affinity chromatography of biotinylated H1° RNA-protein complexes on streptavidin-conjugated paramagnetic particles. The purified proteins maintain RNA-binding ability and preference for histone messag…
