The aim of this study was to evaluate the diversity and abundance of aphids and aphidophagous beneficials in courgettes and potato fields in the Shandong province, East of China. The assessment of aphid and related beneficial populations was conducted between May 9th and June 13th, 2011, using yellow traps and in situ observations on plants. A total of 53,206 insects were trapped and 35,144 observed on the plants. Aphids widely predominated in the traps and exerted a strong pressure on both crops early in the season. Two main species were identified on the plants, namely Aphis gossypii on the courgettes and Myzus persicae on the potatoes. Ladybirds were the most abundant aphidophagous predators, especially Coccinella septempunctata on the courgettes and Propylea japonica on the potato fields, the first one being earlier than the second. Only few hoverflies and lacewings were captured. Microhymenoptera appeared later in the season. The Aphidius gifuensis species represented the majority of trapped Braconidae, while the family Aphelinidae contained the largest number of individuals in the aphidiphagous. [less ▲]

Garantir la durabilité d’une filière de production implique d’évaluer son impact sur les trois dimensions du développement durable : (1) maîtrise des impacts sur l’environnement, (2) viabilité économique, (3) attentes sociétales des éleveurs, des citoyens et des consommateurs. Cette recherche s’inscrit dans le cadre de la révision, par les autorités publiques de Wallonie (Belgique), des critères minimaux permettant la reconnaissance de la qualité différenciée axés sur les 3 piliers de la durabilité. Elle consiste à développer un outil informatique de modélisation mathématique du fonctionnement technico-environnemental de la production porcine et de ses impacts socio-économiques. Le programme est développé dans Matlab. Le modèle s’articule autour des différentes composantes des systèmes de production selon le paradigme orienté-objet. Les nouveaux critères de différenciation qui définiront de nouveaux labels axés sur des attributs de durabilité en constituent les variables motrices : taille de l’exploitation, origine des aliments et des matières premières, logement, indépendance énergétique, effluents, etc. Les impacts sont relevés à chaque étape de production jusqu’à la sortie du porc sur pied de la ferme selon la norme « Analyse de Cycle de Vie » (ACV). L’évaluation environnementale utilise des modèles mécanistiques de flux de composés chimiques, convertis en indicateurs ACV. L’analyse de la dimension sociale s’appuie sur une base de données intégrée, comprenant le temps de travail. Enfin, un modèle économique attestera du dernier volet. L’outil finalisé permettra de prédire les conséquences de choix opérationnels liés aux critères de qualité différenciée au niveau d’une exploitation. [less ▲]

In the latter case, the theory is illustrated by a comparison of symmetrical and asymmetrical face milling from the point of view of tool life. [less ▲]

Scintigraphy of the respiratory system, a technique used extensively in human medecine, provides a direct and non-invasive measure of both total and regional ventilation and perfusion of each lung. This article remind you some nuclear notions and describes scintigraphical techniques for horses. The resuits of studies suggest that ventilation! perfusion scintigraphy provides valuable additionnai informations on regional lung function that are not obtainable from conventional investigations. The mucociliary clearance rates from the trachea can be determinated using scintigraphy and the differenttherapeutic drugs, which are claimed to increase mucokinesis, are successively presented. Methods of radiation protection in equine nuclear medecine are described [less ▲]

During the last years, GFR estimation has received substantial attention with a focus on comparing results of new formulas with GFR measurements, and standardization of creatinine assays. Calibration of creatinine should improve performances. However, frequently used equations have lower precision in high GFR populations. This is the reason why a continuous effort in improving predicting equations is still needed. The use of calibrated creatinine, the onset of new GFR markers such as cystatin C, and pooling data across many study populations are underway to develop better prediction. [less ▲]

Introduction: For several years, respiratory muscles strength can be assessed by various non-invasive or invasive methods. This evaluation is becoming essential in the context of several respiratory diseases. Methods: In a randomized study, 40 healthy subjects purchased respiratory tests (Sniff Nasal Inspiratory Pressure (SNIP), peak inspiratory pressure (PImax) and maximal expiratory pressure (PEmax)) includes a measure of their forced vital capacity and strength of respiratory muscles. Influence of various anthropometric parameters on respiratory muscles strength was assessed through the Macro 5000®, with voluntary and non-invasive tests (SNIP, PImax and PEmax). Results: Gender, height and weight have a significant influence on respiratory muscle strength. Conclusions: Macro 5000® allows the measurement of standardized and reproducible data on respiratory muscles strength (SNIP, PImax and PEmax), in a protocol of about thirty minutes. It also checks the influence of different factors when measuring respiratory muscles strength. [less ▲]

In order to determine if a vocal performance is “in tune” or “out of tune”, to better understand the causes of poor-pitch singing or to evaluate the quality of a singer, tools are necessary. Two methods are actually used to evaluate the vocal accuracy of a sung performance. The "subjective" method makes use of judges whereas the "objective" method uses computer tools. While the first method allows a rapid assessment, it lacks precision. The “objective” method seems currently preferred but shows limits that our research aims to overcome. The first step was to develop a functional and objective method, which takes into account the different melodic errors we encounter when using the Western tonal system (i.e. respect of the melodic contours, the pitch intervals, and the tonal center). We then applied this method to sung performances of occasional and professional singers. These first studies confirmed the functionality and legitimacy of our method. However, some limits occurred regarding the evaluation of Western operatic singers. In a second step, we observed the relevance of this method and more specifically the interest to evaluate complete melodies (compared to pitch matching tasks) and the interest to differentiate the possible melodic errors. Finally, the comparison of our method with the evaluation made by music experts has enabled us to examine their perception and definition of vocal accuracy. Through seven studies, we explored the theoretical and methodological aspects of vocal accuracy in a melodic context. Taken together, the results of these studies allow us to clarify the definition of vocal accuracy and to consider the several clinical and experimental perspectives of our objective method for evaluating singing voice accuracy.
