Body size, body composition and motor performances of mild-to-moderately undernourished senegalese children

Les relations entre dimensions anthropométriques (stature, poids, circonférences de bras et du mollet ainsi que quatre plis cutanés) et les performances motrices (course rapide, saut en longueur sans élan, lancer et force dynamométrique) ont été considérées chez 348 enfants sénégalais de 5 à 13 ans (168 garçons et 180 filles) légèrement ou modérément sous-nutris. Les poids et les statures sont en moyenne inférieurs aux valeurs médianes de référence du National Center for Health Statistics (NCHS) à chaque âge, les écarts sont plus prononcés chez les enfants de plus de huit ans et chez les garçons plus que chez les filles. Les garçons obtiennent en moyenne de meilleurs résultats que les filles pour toutes les activités. La stature et le poids expliquent de 30% à 50% de la variance dans les performances des enfants de moins de dix ans, tandis que le poids en explique de 10% à 25% chez les enfants de plus de dix ans. Les indicateurs de composition corporelle (estimation des parts de muscle et de graisse sous-cutanée du bras) ne contribuent que modérément à la variance restante des performances motrices. L'adiposité affecte négativement les performances des filles de plus de dix ans mais n'influe pas sur celles des garçons. (Résumé d'auteur

The Impact of Advanced Biofuels on Aviation Emissions and Operations in the U.S.

We analyze the economic and emissions impacts on U.S. commercial aviation of the Federal Aviation Administration’s renewable jet fuel goal when met using advanced fermentation (AF) fuel from perennial grasses. These fuels have recently been certified for use in aircraft and could potentially provide greater environmental benefits than aviation biofuels approved previously. Due to uncertainties in the commercialization of AF technologies, we consider a range of assumptions concerning capital costs, energy conversion efficiencies and product slates. In 2030, estimates of the implicit subsidy required to induce consumption of AF jet fuel range from $0.45 to$20.85 per gallon. These correspond to a reference jet fuel price of $3.23 per gallon and AF jet fuel costs ranging from 4.01 to$24.41 per gallon. In all cases, as renewable jet fuel represents around 1.4% of total fuel consumed by commercial aviation, the goal has a small impact on aviation operations and emissions relative to a case without the renewable jet fuel target, and emissions continue to grow relative to those in 2005. Costs per metric ton of carbon dioxide equivalent abated by using biofuels range from $42 to$652.This work is funded by the U.S. Federal Aviation Administration (FAA) and Defense Logistics Agency Energy (DLA Energy) through Project 47 of the Partnership for Air Transportation Noise and Emissions Reduction (PARTNER).

Three-dimensional fluorescent microscopy via simultaneous illumination and detection at multiple planes.

The conventional optical microscope is an inherently two-dimensional (2D) imaging tool. The objective lens, eyepiece and image sensor are all designed to capture light emitted from a 2D 'object plane'. Existing technologies, such as confocal or light sheet fluorescence microscopy have to utilize mechanical scanning, a time-multiplexing process, to capture a 3D image. In this paper, we present a 3D optical microscopy method based upon simultaneously illuminating and detecting multiple focal planes. This is implemented by adding two diffractive optical elements to modify the illumination and detection optics. We demonstrate that the image quality of this technique is comparable to conventional light sheet fluorescent microscopy with the advantage of the simultaneous imaging of multiple axial planes and reduced number of scans required to image the whole sample volume

A prospective analysis of the injury incidence of young male professional football players on artificial turf

Background: The effects of synthetic surfaces on the risk of injuries is still debated in literature and the majority of published data seems to be contradictory. For such reasons the understanding of injury incidence on such surfaces, especially in youth sport, is fundamental for injury prevention. Objectives: The aim of this study was to prospectively report the epidemiology of injuries in young football players, playing on artificial turfs, during a one sports season. Patients and Methods: 80 young male football players (age 16.1 ± 3.7 years; height 174 ± 6.6 cm; weight 64.2 ± 6.3 kg) were enrolled in a prospective cohort study. The participants were then divided in two groups; the first included players age ranging from 17 to 19 (OP) whereas the second included players age ranging from 13 to 16 (YP). Injury incidence was recorded prospectively, according to the consensus statement for soccer. Results: A total of 107 injuries (35 from the OP and 72 from the YP) were recorded during an exposure time of 83.760 hours (incidence 1.28/1000 per player hours); 22 during matches (incidence 2.84/1000 per player hours, 20.5%) and 85 during training (incidence 1.15/1000 per player hours, 79.5%). Thigh and groin were the most common injury locations (33.6% and 21.5%, respectively) while muscle injuries such as contractures and strains were the most common injury typologies (68.23%). No statistical differences between groups were displayed, except for the rate of severe injuries during matches, with the OP displaying slightly higher rates compared to the YP. Severe injuries accounted for 10.28% of the total injuries reported. The average time lost due to injuries was 14 days. Re-injuries accounted for 4.67% of all injuries sustained during the season. Conclusions: In professional youth soccer injury rates are reasonably low. Muscle injuries are the most common type of injuries while groin and thigh the most common locations. Artificial turf pitches don’t seem to contribute to injury incidence in young football players

Promotion expenditure, categories, time lag structure and the demand for almonds

The Almond Board of California (ABC) finances four promotional programs to increase the demand for California almonds: public relations, advertising, food services and nutrition research. This analysis relates ABC's expenditures by category to U.S. almond demand. It assesses ABC's return on investment and guides managerial decisions across programs. ABC expenditures have a significant effect on domestic almond shipments, explaining 16.7% of the variation in shipments. However, only advertising is strongly significanteach dollar spent increases almonds shipped eight months later by 8.25 pounds. Food services approached significanceeach dollar spent increases almonds shipped 11 months later by 32.8 pounds.Approved for public release; distribution is unlimited

non-linear relationships in children 6-10 years

Background: Given the concern for health?related consequences of an elevated body mass index (BMI; obesity), the potential consequences of a low BMI in children are often overlooked. The purpose was to evaluate the relationship between the BMI across its entire spectrum and motor coordination (MC) in children 6?10 years. Methods: Height, weight, and MC (K?rperkoordinationstest f?r Kinder, KTK test battery) were measured in 1,912 boys and 1,826 girls of 6?10 years of age. BMI (kg/m2) was calculated. KTK scores for each of the four tests were also converted to a motor quotient (MQ). One?way ANOVA was used to test differences in the BMI, individual test items, and MQ among boys and girls within age groups. Sex?specific quadratic regressions of individual KTK items and the MQ on the BMI were calculated. Girls and boys were also classified into four weight status groups using International Obesity Task Force criteria: thin, normal, overweight, and obese. Differences in specific test items and MQ between weight status groups were evaluated by age group in each sex. Results: Thirty?one percent of the sample was overweight or obese, whereas 5% was thin. On average, normal weight children had the highest MQ in both sexes across the age range with few exceptions. Overweight/obese children had a lower MQ than normal weight and thin children. The quadratic regression lines generally presented an inverted parabolic relationship between the BMI and MC and suggested a decrease in MC with an increase in the BMI. Conclusion: In general, BMI shows a curvilinear, inverted parabolic relationship with MC in children 6?10 years.4811-99FE-2ECD | Luis Paulo Rodriguesinfo:eu-repo/semantics/publishedVersio
