Radiative surface temperature and convective flux calculation over crop canopies

1988

The analysis presented in this paper aims at a better understanding of the potential role of radiative temperature, as measured by a radiometer over crops, in sensible heat flux calculation. Defining radiative temperature as the mean temperature of the surfaces viewed by the radiometer (leaves and soil surface) and assuming that an Ohm's law type formula can be used to express sensible heat flux as a function of the difference between air temperature and radiative temperature, the aerodynamic resistance which divides this temperature difference has been analytically defined. The parameters which appear in the resistance expression depend essentially on wind velocity and canopy structure but…

Interactions surface continentale/atmosphère : l'expérience HAPEX-Sahel

1994

L'évolution saisonnière des termes du bilan radiatif, du bilan d'énergie et la production primaire d'une savane humide d'Afrique de l'Ouest (Lamto, Côte d'Ivoire) a été suivie dans le cadre du programme SAvanes à Long Terme (SALT). Ces données ont permis de développer un modèle de simulation des échanges surface/atmosphère en savane humide, basé sur les relations fonctionnelles existant entre la production et la phénologie de la savane d'une part, et les bilans d'énergie et hydrique de ce type de surface d'autre part. Ce modèle est issu du couplage de deux sous-modèles fonctionnant au pas de temps journalier et utilisant des variables climatiques standard en entrée : le modèle de bilan d'én…

Fluxapyroxad Haptens and Antibodies for Highly Sensitive Immunoanalysis of Food Samples

2017

Fluxapyroxad is a new-generation carboxamide fungicide, with residues increasingly being found in food samples. Immunochemical assays have gained acceptance in food quality control as rapid, cost-effective, sensitive, and selective methods for large sample throughput and in situ applications. In the present study, immunoreagents to fluxapyroxad were obtained for the first time, and competitive immunoassays were developed for the sensitive and specific determination of fluxapyroxad residues in food samples. Two carboxyl-functionalized analogues of fluxapyroxad were prepared, and antibodies with IC50 values in the low nanomolar range were generated from both haptens, though a dissimilar respo…

Antibody generation and immunoassay development in diverse formats for pyrimethanil specific and sensitive analysis

2012

Immunochemical techniques are complementary tools to modern analytical requirements. These methods rely on the production of immunoreagents with adequate binding properties. In the present study, a rationally designed and functionalized derivative of pyrimethanil-a modern anilinopyrimidine fungicide-was synthesized in order to generate for the first time high-affinity and selective antibodies to this xenobiotic. A single coupling procedure-based on hapten activation using N,N′-disuccinimidyl carbonate and purification of the active ester-was followed to prepare both immunizing and assay conjugates. Polyclonal antibodies were produced and characterized by enzyme-linked immunosorbent assay (E…

Jubileusz 25-lecia Muzeum Diecezjalnego w Opolu

2013

Across the ages the Church has been concerned with the cultural heritage of its members. The mid-eighteenth century witnessed discernible interest in religious objects excluded from the cult and emphasis was placed on the evangelisation role of church museums, which, interested in the fate of useless artworks removed from church interiors, collected, stored, and conserved them as well as rendered them available to society. The anniversary of the Diocesan Museum in Opole became an excellent occasion for taking a closer look at its history and assess the part it played in the course of the past quarter of a century. The idea of establishing such a museum dates back to 1978 – the year when Alf…

Les graphes paysagers pour la modélisation et la gestion des pullulations de campagnols terrestres.

2016

International audience; Les prairies d’Auvergne et de Franche-Comté sont régulièrement envahies par un rongeur, le campagnol terrestre. Le projet CAMPAGRAPHE vise à fournir un appui pour la mise en place d’un dispositif agro-écologique limitant sa diffusion grâce à une modélisation des réseaux de prairies.Le graphe obtenu permet de localiser des actions de terrain et orienter le suivi des populations.

Evaluation of TKTL1 as a biomarker in serum of prostate cancer patients.

2016

Introduction Monocyte associated transketolase-like 1 (TKTL1) as a cancer biomarker has become popular with alternative practitioners, but plays no role in conventional medicine. This investigation evaluates the potential of serum TKTL1 as a biomarker for prostate cancer. Material and methods Patients (n = 66) undergoing curative radical prostatectomy (RPE) for biopsy-pro-ven PCa were included in the study. Controls (n = 10) were healthy, age-matched, male volunteers. 10 ml of peripheral blood was drawn from patients several days before surgery and from controls. Serum TKTL1 was measured using the ELISA method. Results The median age at tumor diagnosis was 66 years and median serum PSA was …

Klotho urinario determinado por ELISA como biomarcador precoz de fracaso renal agudo en pacientes sometidos a cirugía cardiaca o angiografía coronaria

2015

ResumenIntroducción y objetivos: El fracaso renal agudo (FRA) es una complicación frecuente tras la cirugía cardiaca y las intervenciones percutáneas coronarias cuya aparición empeora el pronóstico de manera marcada. En los últimos años se han identificado nuevos biomarcadores precoces de FRA, pero aún quedan muchos aspectos importantes por resolver. Klotho es una proteína pleiotrópica que actúa como un factor paracrino y endocrino en múltiples órganos. En diversos modelos animales de FRA se ha demostrado niveles disminuidos de Klotho renal. No se ha publicado ningún estudio en el que se haya probado Klotho como marcador precoz de FRA en humanos. El objetivo de este trabajo es investigar la…
