Quantifier elimination in the quasi-analytic framework
2012
We associate to every compact polydisk B [belonging to ] Rn an algebra CB of real functions defined in a neighborhood of B. The collection of these algebras is supposed to be closed under several operations, such as composition and partial derivatives. Moreover, if the center of B is the origin, we assume that the algebra of germs at the origin of elements of CB is quasianalytic (it does not contain any flat germ). We define with these functions the collection of C-semianalytic and C-subanalytic sets according to the classical process in real analytic geometry. Our main result is an analogue of Tarski-Seidenberg's usual result for these sets. It says that the sub-C-subanalytic sets may be d…
A method for the preparation of repacked soil cores with homogeneous aggregates for studying microbial nitrogen transformations under highly controll…
1998
International audience; he feasibility of studies on nitrate transformations during incubation in controlled conditions of air-filled porosity using a method of soil core preparation was investigated. Repacked cores were obtained by uniaxial confined compression in a cylindrical mould of a mass of calibrated and conveniently wet aggregates with a water content selected to saturate the textural porosity of the soil aggregates, imposing structural porosity and thereby producing controlled conditions of aeration. The principle and the descrip- tion of the incubation method are explained and some denitrification and respiration data obtained with low and increasing OZ partial pressures are pres…
Effect of onion consumption by rats on hepatic drug-metabolizing enzymes
2001
Fruits and vegetables or their natural constituents which increase detoxication enzymes and/or reduce activating enzymes are considered as good candidates to prevent chemically-induced carcinogenesis. In this study, rats were fed a diet supplemented with 20% onion powder for 9 days. Several cytochrome P450 (CYP)s enzymes (CYP 1A, 2B, 2E1, 3A), which are involved in carcinogen activation, were determined by measuring their enzyme activities using specific substrates. In addition, phase II enzymes activities such as UDP-glucuronosyltransferase (UGT) and glutathione S-transferase (GST), involved in detoxication of carcinogens, were measured. Protein levels of CYPs and GST A1/A2, A3/A5, Ml, M2 …
Application of seaweeds to develop new food products with enhanced shelf-life, quality and health-related beneficial properties
2017
International audience; Edible seaweeds are a good source of antioxidants, dietary fibers, essential amino acids, vitamins, phytochemicals, polyunsaturated fatty acids, and minerals. Many studies have evaluated the gelling, thickening and therapeutic properties of seaweeds when they are used individually. This review gives an overview on the nutritional, textural, sensorial, and health-related properties of food products enriched with seaweeds and seaweed extracts. The effect of seaweed incorporation on properties of meat, fish, bakery, and other food products were highlighted in depth. Moreover, the positive effects of foods enriched with seaweeds and seaweed extracts on different lifestyl…
Le passage de Haies: De la réalité sportive en heptathlon à la réalité subjective d'Emma
2006
The major dimension of this article is to point out the importance of psychological follow-up with sporting teenagers. Emma's example illustrates the inherent transitions from this period of age in the specific context of the high level sport. For Emma, the passage of hurdle becomes the metaphor of its psychical conflict. The counter performance which appears in the passage of hurdle announces its ambivalence with regard to its personal history within realities of sport cultures. This making sense of the sporting problems within the framework of the psychological follow-up can help to exceed this difficulty of passage and to support its engagement like subject of its own desire on the way o…
Dažādas lokalizācijas taukaudu relatīvā daudzuma un ķermeņa kopējās tauku masas korelatīvs izvērtējums jaunām sievietēm
2019
Palielinoties kardio-metabolo saslimšanu biežumam pasaulē un arī Latvijā, arvien lielāku nozīmi iegūst šo veselības risku agrīna atpazīšana un prevencijas pasākumu ieviešana to novēršanai. Šobrīd praktiskajā medicīnā nav vienotu priekšstatu par kardio-metabolo saslimšanu riska marķieru kombināciju, ko varētu izmantot efektīvai veselības risku atpazīšanai un novēršanai. Maģistra darba pētījuma mērķis bija izvērtēt ar dažādām metodēm noteiktu biežāk izmantoto kardio-metabolo saslimšanu riska marķieru savstarpējo saistību sievietēm ar atšķirīgu ķermeņa kopējo tauku masu. Pētījumā piedalījās 43 jaunas, klīniski veselas sievietes vecumā no 18 līdz 28 gadiem. Pētījuma dalībniecēm noteica ķermeņa …
Aproximación a la dimensión socio-emocional del profesorado de Educación Secundaria en el aula actual: propuesta para la adquisición de competencias …
2014
La inteligencia socio-emocional es, sin lugar a dudas, una asignatura pendiente a nivel educativo. Las competencias básicas respecto a este campo están bastante definidas para el estudiante, pero no así para el docente. Sin embargo, es él quien debe enseñarlas y transmitirlas. Intentamos en el presente trabajo dar una orientación sobre las cualidades que debe poseer un profesor para poder ser considerado socio-emocionalmente competente, así como de las actitudes saludables que puede desarrollar con tal fin. The social and emotional intelligence is, without doubt, an unfinished educational subject. The basic competences in this field are quite defined for student, but not for teachers. Howev…
Rendimiento deportivo y edades formativas en baloncesto desde un enfoque de contingencias
2021
Originada en el ámbito económico y administrativo, la teoría de las contingencias es otra visión con la que observar el mundo del rendimiento deportivo. Esta tesis es un compendio de tres artículos en el que se analizan algunas contingencias que podrían influenciar a los jugadores de baloncesto en edades formativas. En función de ello, el estudio 1 tuvo como objetivo analizar la influencia de la música motivacional sobre la velocidad aeróbica máxima intermitente y la agilidad, en un grupo de jugadores jóvenes de baloncesto bien entrenados (13 sujetos, 14,85 ± 0,68 años), en comparación con música menos motivante y/o ausencia de música. La música motivacional se confirmó como herramienta cap…
Individuality in the Early Number Skill Components Underlying Basic Arithmetic Skills
2018
Early number skills underlie success in basic arithmetic. However, very little is known about the skill profiles among children in preprimary education and how the potential profiles are related to arithmetic development. This longitudinal study of 440 Finnish children in preprimary education (mean age: 75 months) modeled latent performancelevel profile groups for the early number skill components that are proposed to be key predictors of arithmetic (symbolic number comparison, mapping, and verbal counting skills). Based on three assessment time points (September, January, and May), four profile groups were found: the poorest-performing (6%), low-performing (16%), nearaverage-performing (33…
Aptiekā pieejamo homeopātisko līdzekļu popularitāte lietotāju vidū
2022
Homeopātija ir specifiska alternatīvās medicīnas ārstniecības metode, par kuras efektivitāti sabiedrībā un veselības aprūpes speciālistu vidū ir vērojama polarizēta attieksme. No materiālisma viedokļa šai alternatīvās ārstniecības metodei nav racionālu pierādījumu varbūtējai efektivitātei. Arī zinātniskajā literatūrā klīnisko pētījumu informācija par šīs terapijas efektivitāti liecina, ka tā ir vienāda ar placebo efektu, tomēr ir virkne ārstu un pacientu, kuri šai metodei atrod skaidrojumu un praktisko pielietojumu. Bakalaura darbā sniegti aptiekas apmeklētāju aptaujas rezultāti par homeopātisko līdzekļu efektivitātes subjektīvo vērtējumu un izanalizēti dati, kurus aptiekā piedāvātos homeop…
