Public health nurses' approaches to early childhood physical activity in Finland.
2009
This study was conducted using five focus groups with 24 public health nurses from regional child health clinics in order to explore health professionals' perceptions concerning physical activity. Participants were professionally experienced (mean 13.9 years), female (mean 46.2 years) nurses with some training in health-enhancing physical activity. Frame analysis of verbatim transcripts resulted in four frames: the environmental frame, the family frame, the natural frame and the wellbeing and health frame. The importance of physical and social environment, especially the role of parents, was highlighted as determinants of physical activity. Furthermore, the natural characteristics of physi…
Mixed methods analysis of Health-Related Quality of Life in ambulant individuals affected with RYR1-related myopathies pre-post-N-acetylcysteine ther…
2020
Purpose: To characterize Health-Related Quality of Life (HRQoL) in ambulant individuals with RYR1-RM and to determine if a qualitative PRO tool (subjective self-assessment) complements PROMIS and Neuro-QoL scales to detect changes in HRQoL in ambulant individuals with RYR1-RM post N-acetylcysteine (NAC) treatment. Methods: The study used a mixed methods research (MMR) design applying methodological triangulation. Qualitative data were collected via semi-structured interviews using open-ended questions. Quantitative data were gathered through PROMIS and Neuro-QoL instruments. Additionally, qualitative data were transformed into quantitative data for subjective self-assessment and frequency a…
African Law(s)
2023
The book presents a critical rethinking of the study of law in Africa from a comparative law perspective and proposes a new approach on how to consider law in Africa. It highlights the inadequacies of current Western theoretical perspectives in comparative law, especially for studying African law, arguing that they are too eurocentric to fully catch the peculiarities and characteristics of the African “lawscape”. The common thread of the present work is that of consider law in Africa from a different perspective. The aim of the proposed approach is to demonstrate that the African legal culture can be considered at the same level of the Western one, so that – being deeply rooted in the cultu…
Comparative Law in the African context
2015
The article paves the way to the creation of a specific comparative law methodology for the studies of African legal system in a comparative perspective.
A Combination of Visible-Light Organophotoredox Catalysis and Asymmetric Organocatalysis for the Enantioselective Mannich Reaction of Dihydroquinoxal…
2019
[EN] An enantioselective photooxidative Mannich reaction of dihydroquinoxalinones with ketones by the merger of organophotoredox and asymmetric organocatalysis is described. This protocol features very mild reaction conditions using simple and cheap catalysts (Eosin Y and (S)-Proline) for the synthesis of chiral quinoxaline derivatives with good to high yields (up to 94%) and excellent enantioselectivities (up to 99% ee).
Place and Positionality – Anthropo(topo)logical Thinking with Helmuth Plessner
2018
This paper explores a possible anthropological dimension of place by providing an interpretation of Helmuth Plessner’s philosophical approach which proposes to understand it as a twofold “implacement” of man – discussing both the place of man in the natural world and man’s specific relation to place that makes him take his place in the natural world. The interpretation follows Plessner’s idea of a natural set of stages, developed in his major work Die Stufen des Organischen und der Mensch, leading from inanimate objects to plants, animals, and humans. According to Plessner, each stage differs from the other by virtue of its respective spatial delineation toward, and its position in, the wor…
Negative-pressure cavitation extraction of cajaninstilbene acid and pinostrobin from pigeon pea [Cajanus cajan (L.) Millsp.] leaves and evaluation of…
2011
Abstract In this study, an efficient negative-pressure cavitation extraction (NPCE) technique was developed to extract cajaninstilbene acid (CSA) and pinostrobin (PI) from pigeon pea [Cajanus cajan (L.) Millsp.] leaves. The operating parameters were optimised using single-factor experiment and central composite design combined with response surface methodology. Well-fitting models for the extraction of CSA and PI were successfully established. From the economic perspective, the selected operating parameters were: extraction pressure −0.075 MPa, extraction temperature 45 °C, material size 40 mesh, ethanol concentration 80%, extraction time 30 min, liquid/solid ratio 30:1 and 4 extraction cyc…
Stevia rebaudiana Bertoni as a natural antioxidant/antimicrobial for high pressure processed fruit extract: Processing parameter optimization
2013
Response surface methodology was used to evaluate the optimal high pressure processing treatment (300-500 MPa, 5-15 min) combined with Stevia rebaudiana (Stevia) addition (0-2.5% (w/v)) to guarantee food safety while maintaining maximum retention of nutritional properties. A fruit extract matrix was selected and Listeria monocytogenes inactivation was followed from the food safety point of view while polyphenoloxidase (PPO) and peroxidase (POD) activities, total phenolic content (TPC) and antioxidant capacity (TEAC and ORAC) were studied from the food quality point of view. A combination of treatments achieved higher levels of inactivation of L. monocytogenes and of the oxidative enzymes, s…
Solvent-free microwave-assisted extraction of polyphenols from olive tree leaves: Antioxidant and antimicrobial properties
2017
International audience; Response surface methodology (RSM) and artificial neural networks (ANN) were evaluated and compared in order to decide which method was the most appropriate to predict and optimize total phenolic content (TPC) and oleuropein yields in olive tree leaf (Olea europaea) extracts, obtained after solvent-free microwave- assisted extraction (SFMAE). The SFMAE processing conditions were: microwave irradiation power 250-350 W, extraction time 2-3 min, and the amount of sample 5-10 g. Furthermore, the antioxidant and antimicrobial activities of the olive leaf extracts, obtained under optimal extraction conditions, were assessed by several in vitro assays. ANN had better predic…
Evaluación de las actividades realizadas mediante la metodología de Aprendizaje Basado en Problemas
2020
[ES] La metodología de Aprendizaje Basado en Problemas (ABP) requiere un enfoque de evaluación en el que se evalúen una serie de competencias específicas y transversales. Esta evaluación debe de tener un carácter formativo que permita a los estudiantes identificar y corregir los errores a tiempo. Por lo tanto, es necesario disponer de herramientas para poder evaluar apropiadamente los resultados de aprendizaje y las competencias establecidas. En la asignatura de Corrosión de segundo de Máster de Ingeniería Química, el ABP se ha evaluado a través de un informe a entregar tras cada sesión de ABP, en donde se recogen las principales conclusiones tras la resolución cooperativa del problema plan…
