Microstructural, chemical and textural records during growth of snowball garnet

2009

The growth history of two populations of snowball garnet from the Lukmanier Pass area (central Swiss Alps) was examined through a detailed analysis of three-dimensional geometry, chemical zoning and crystallographic orientation. The first population, collected in the hinge of a chevron-type fold, shows an apparent rotation of 360 degrees. The first 270 degrees are characterized by spiral-shaped inclusion trails, gradual and concentric Mn zoning and a single crystallographic orientation, whereas in the last 90 degrees, crenulated inclusion trails and secondary Mn maxima centred on distinct crystallographic garnet domains are observed. Microstructural, geochemical and textural data indicate a…

Changes in the Intra-Metropolitan Location of Producer Services in Ile-de-France (1978-1997) : do information technologies promote a more dispersed s…

2003

Because of their intensive need for face-to-face contacts, producer services have, historically, been found at the core o f CBDs. However, it has been suggested that advances in information technologies could lead to the erosion o f the CBD’s economic base, rendering face-to-face contacts obsolete and enabling producer services to suburbanize. Although a considerable amount o f empirical work has been done on the suburbanization o f these activities in North-America, the same is not true of France. In this paper, we adopt an original methodology to study the role played by face-to-face contacts in the spatial distribution of producer services in the Ile-de-France region between 1978 and 199…

Examining the Impact of ICT on Sustainable Development: A Data-Driven Narrative

2021

Considering the challenges of sustainable development and the mixed prescriptions being offered by the use of digital technologies, we present a data-driven narrative of how ICT development impacts the sustainable growth of economies. The analysis is based on historical panel data from 39 economies across the developed and developing economies. The industry-standard CRISP-DM methodology was applied as it is flexible, robust, and offers a practical approach for data analytics. The findings reveal that there are differentiated outcomes in terms of sustainable growth among high-income and low-income economies. This poses legitimate questions as to whether low-income economies will be able to m…

Sprint Acceleration Mechanics in Fatigue Conditions: Compensatory Role of Gluteal Muscles in Horizontal Force Production and Potential Protection of …

2018

Aim: Hamstring muscle injury is the main injury related to sports requiring sprint acceleration. In addition, hamstring muscles have been reported to play a role in horizontal force production during sprint acceleration performance. The aim of the present study was to analyze (i) the determinants of horizontal force production and (ii) the role of hip extensors, and hamstring muscles in particular, for horizontal force production during repeated sprint-induced fatigue conditions. Method: In this experimental laboratory setting study including 14 sprint-trained male athletes, we analyzed (i) the changes in sprint mechanics, peak torque of the knee and hip extensors and flexors, muscle activi…

Training the Vertical Jump to Head the Ball in Soccer

2012

R esearchers involved in the training methodology to improve jump ability proposed a variety of techniques and exercise modalities (22,15,4). Nevertheless, the question on what percentage of training should be dedicated to strength and what to power seems unresolved. First of all, to better understand the matter, we have to stress the difference between strength and power. Generally speaking, in athletics, the rate of force development (RFD) is much more important than strength alone; the average RFD (mRFD) can be estimated as the ratio Fmax/Tmax, where Tmax is the time to reach the peak force, whereas Fmax is the maximum force. This ratio is also named explosive strength, commonly computed…

Responses to eccentric rotation in two space-bound subjects

1993

Two subjects were rotated eccentrically in the manner described previously. In contrast to a normal control group, settings of a luminous line to the subjective vertical were almost unrelated to the gravitoinertial vector before, and totally so shortly after, space flight. Only 3 days postflight did a clear relation to the gravitoinertial vector re-establish itself in the one subject who actually flew. The correspondence became normal 5 days after the flight. Since there were no clinical abnormalities evident in the subjects, it is suggested that both subjects suppressed their vestibular information, presumably as an effect of vestibular deconditioning training before the flight. In additio…

Eccentric fixation measurements using visuoscopy and Macula Integrity Tester (MIT) in children with amblyopia

2021

The aim of the work was to compare measurements of eccentric fixation in children with amblyopia using two different methods, a traditional visuoscopy and MIT. Monocular fixation was evaluated using visuoscopy and MIT in 16 patients (from 5 to 9 years old). Measurements were started with the better seeing eye to compare the results obtained with the amblyopic eye. All study participants were selected with anisometropic and refractive amblyopia. Visuoscopy is simpler than MIT and less dependent on patient responses, so visioscopy can be used for young children who have not yet acquired verbal skills. Children over the age of 5 can more easily understand the MIT method and get more reliable r…
