Lignin recovery from spent alkaline pulping liquors using acidification, membrane separation, and related processing steps: A Review

2019

The separation of lignin from the black liquor generated during alkaline pulping is reviewed in this article with an emphasis on chemistry. Based on published accounts, the precipitation of lignin from spent pulping liquor by addition of acids can be understood based on dissociation equilibria of weak acid groups, which affects the solubility behavior of lignin-related chemical species. Solubility issues also govern lignin separation technologies based on ultrafiltration membranes; reduction in membrane permeability is often affected by conditions leading to decreased solubility of lignin decomposition products and the presence of colloidal matter. Advances in understanding of such phenomen…

Browsing hinders the regeneration of broadleaved trees in uneven-aged forest management in southern Finland

2020

Uneven-aged forest management has attained increasing popularity. It may benefit biodiversity, buffer against pests and abiotic damages, decrease runoff from clearcuts and improve recreational values. We studied how gap cuttings and single-tree selection cuttings influence browsing damage in spruce-dominated forests in south-central Finland. Overall, browsing damage was especially frequent in aspen and rowan, but also in birch. The larger the basal area left in harvesting, the lower the browsing pressure on birch and rowan; neither the harvesting method nor the seedling density had an independent effect on browsing damage. Although larger tree retention levels may reduce browsing damage, th…

Le goût de la récolte. Cueillir son vin du XIVe siècle à nos jours

2011

National audience; S'imposant comme modalité officielle pour encadrer la récolte, la pratique du ban n'a été supprimée que très récemment en Bourgogne. Jadis acte de l'autorité seigneuriale, le ban est associé à une pratique documentée dans les archives depuis les années 1370. Il est ainsi possible d'étudier de façon continue les modalités de la vendange depuis cette époque. Cela signifie aussi, d'un point de vue social, qu'une décision collective préside à la récolte des raisins sur le temps long, récolte qui engage la qualité et les caractères du vin qui sera produit, sachant que jusqu'au XVIIIe siècle les réflexions précieuses sur la vinification ont un assez faible écho. Dans les source…

The eastern regions of Al-Andalus before the conquest by Catalonia-Aragon: An overview

2012

This article sets forth a highly schematic synthesis of current knowledge on the history of the eastern regions of Al-Andalus, particularly Tortosa, Valencia and the Balearic Islands, before they were conquered by the Crown of Aragon between the 12th and 13th centuries. After presenting the informational records on this region, we shall describe the main features in the construction of a society and a political order grounded on Arab-Berber immigrants and the creation of a new agrarian ecosystem. Finally, we shall offer observations of the nature of the legal power and the forms in which authority was exercised.

Narrative inquiry and historical skills. A study in teacher training

2017

This paper addresses narrative thinking and literacy levels in future primary school teachers in Spain. It uses the study of a historical synthesis of one of the main narratives in Spanish history: the Christian expansion through Muslim territories in the Iberian Peninsula in the Middle Ages. Accounts by 283 students of the degree in elementary school teaching at the universities of Valencia and Murcia were studied. The aim was to ascertain the students' discursive abilities with respect to their historical thinking skills. The results reveal poor narrative skills in future teachers and a very low level of historical literacy.

HUMAN MILK IS NOT “MERELY NUTRITIOUS”: HOW ITS BIOACTIVE ROLE CAN INFLUENCE CHILD HEALTH

2021

Maternal milk represents the best food for the newborn, providing specific physiologic advantages over the other sources of nutrition. It also contains many hundreds to thousands of bioactive molecules that protect against infection (i.e. IgA), inflammation (i.e. 5-methylthioadenosine) and contribute to eliciting strong immune responses in breastfed children (i.e. allergens or viral antigens). Quality and quantity of breast milk components may influence the development of infant body composition in the first years of life; in particular, it has been shown that a different composition of human oligosaccharides (HMOs) in overweight/obese women’s human milk can be correlated with her offspring…

The home literacy model in a highly transparent orthography

2019

We investigated the extent to which home literacy activities during the preschool year would predict the development of children’s language and literacy skills in primary school, in a highly transparent Finnish language. Also, the correlates of maternal literacy activities during preschool were examined. Literacy and language skills of 1,880 children (6-year-olds at the baseline) were tested at 5 time points from the beginning of preschool to the end of Year 2; mothers filled in questionnaires at the end of preschool. The results showed that home teaching of reading at preschool age predicted children’s emergent literacy (letter knowledge, word reading fluency) in primary school, while shar…
