Analysis of knee strength measurements performed by a hand-held multicomponent dynamometer and optoelectronic system
The quantification of muscle weakness is useful to evaluate the health status and performance of patients and athletes. In this paper, we proposed a novel methodology to investigate and to quantify the effects induced by inaccuracy sources occurring when using a hand-held dynamometer (HHD) for knee strength measurements. The validation methodology is based on the comparison between the output of a one-component commercial HHD and the outputs of a six-component load cell, comparable in dimension and mass. An optoelectronic system was used to measure HHD positioning angles and displacements. The setup allowed to investigate the effects induced by: 1) the operator's ability to place and to hold still the HHD and 2) ignoring the transversal components of the force exchanged. The main finding was that the use of a single component HHD induced an overall inaccuracy of 5% in the strength measurements if the angular misplacements are kept within the values found in this paper (â€15°) and with a knee range of motion â€22°. Extension trials were the most critical due to the higher force exerted, i.e., 249.4 ± 27.3 versus 146.4 ± 23.9 N of knee flexion. The most relevant source of inaccuracy was identified in the angular displacement on the horizontal plane
An HI interstellar bubble surrounding WR85 and RCW118
We analyze the distribution of the interstellar matter in the environs of the
Wolf-Rayet star LSS3982 (= WR85, WN6+OB?) linked to the optical ring nebula
RCW118. Our study is based on neutral hydrogen 21cm-line data belonging to the
Southern Galactic Plane Survey (SGPS).
The analysis of the HI data allowed the identification of a neutral hydrogen
interstellar bubble related to WR 85 and the 25' diameter ring nebula RCW118.
The HI bubble was detected at a systemic velocity of -21.5 km/s, corresponding
to a kinematical distance of 2.8+/-1.1 kpc, compatible with the stellar
distance. The neutral stucture is about 25' in radius or 21+/-8 pc, and is
expanding at 9+/-2 km/s. The associated ionized and neutral masses amount to
3000 Mo. The CO emission distribution depicts a region lacking CO coincident in
position and velocity with the HI structure. The 9'.3 diameter inner optical
nebula appears to be related to the approaching part of the neutral atomic
shell. The HI void and shell are the neutral gas counterparts of the optical
bubble and have very probably originated in the action of the strong stellar
wind of the central star during the O-type and WR phases on the surrounding
interstellar medium. The HI bubble appears to be in the momentun conserving
stage.Comment: 9 pages, 7 figures, accepted in MNRA
Fundamental domains of cluster categories inside module categories
Let be a finite dimensional hereditary algebra over an algebraically
closed field, and let be the corresponding cluster category.
We give a description of the (standard) fundamental domain of in the bounded derived category , and of the
cluster-tilting objects, in terms of the category \ of finitely
generated modules over a suitable tilted algebra Furthermore, we
apply this description to obtain (the quiver of) an arbitrary cluster-tilted
algebra.Comment: 20 pages, 9 figure
Il Rinascimento degli acquedotti
Dopo il buio Medio Evo rifiorirono le arti nel Rinascimento. Anche
sotto terra, negli acquedotti, si verificĂČ qualcosa di analogo ma
Ăš ben poco noto. Ora si presentano qui quattro esempi di importanti
acquedotti creati nellâEvo Moderno per alimentare castelli
e ville della regione Lazio.
Lâacquedotto che conduce lâacqua dal fiume Aniene alle fontane
del giardino della Villa dâEste a Tivoli fu compiuto nella seconda
metĂ del XVI secolo e consentĂŹ la realizzazione di uno dei piĂč
famosi parchi âallâitalianaâ, tuttora aperto e frequentato da migliaia
di visitatori. LâAcqua Farnesiana Ăš un acquedotto creato
alla fine del XVI secolo per alimentare la villa e il palazzo dei
Farnese a Caprarola, nasce da un capofonte ipogeo in comune
di Canepina, Ăš lungo circa 9 km, con lunghi tratti scavati nella
roccia. Lâacquedotto del castello Ruspoli di Vignanello presenta
un percorso ipogeo sottostante lâantico abitato, Ăš lungo circa 2
km e fu creato dalla contessa Ottavia Orsini allâinizio del XVII secolo.
Lâacquedotto Aldobrandini fu realizzato tra il 1603 e il 1605,
in parte riutilizzando le captazioni e i condotti dellâantica Aqua
Julia, con un condotto di almeno 9,5 km; esso alimentava i giochi
dâacque della villa Belvedere degli Aldobrandini e in parte anche
altre ville, una mola e lâAbbazia di S. Nilo a Grottaferrata. Ă tuttora
in piena efficienza.The fall of the Roman Empire brought into a rapid drop the population
of the main towns; many crashes followed as well as the
discontinuance of the extraordinary network of aqueducts that
supported the survival in many conurbations. The resumption of
the way of life after the twelfth. century fostered the revival of the
fine arts and the architecture: the Renaissance was born. Somewhat
similar took place in the undergrounds, where drinking waters
flow in the ducts. A few examples of important aqueducts
that were set up in the Modern Era are presented: they provided
drinking water to castles and magnificent country houses.
The aqueduct that takes the waters from river Aniene to the
fountains of the Villa dâEste garden in Tivoli has been achieved
in the second half of the 16th century, following the instructions
of Cardinal Ippolito II dâEste: one of the most famous âitalianâ
gardens was attained; the fountains are still perfectly effective
and enjoy thousands visitors every year. âAcqua Farnesianaâ is
an aqueduct set up towards the end of the 16th century, 9 km ca.
long; it sucks up water from an hypogean source in Canepina
(VT) commune and, through a few underground tunnels, it feeds
the Farnese palace, villa and gardens in Caprarola. The Ruspoli
aqueduct flows through an hypogean tunnel below the ancient
built-up area of Vignanello (VT) and is nearly 2 km long. It was set
up by countess Ottavia Orsini at the beginning of the 17th century,
in order to supply the âItalian gardenâ below her castle. The Aldobrandini
aqueduct was achieved from 1603 to 1605 on Popeâs
Clemente VII will, in a large part by the recovery of the underground
springs and ducts created by the Romans for the ancient
aqueduct Aqua Julia and by adding a shorter tunnel leading
straight to the Villa Belvedere in Frascati (RM). The aqueduct is
on the whole 9,5 km long; it was feeding the âItalian gardenâ just
above the Villa, but in part supported other country houses too,
near Frascati, the Saint Nilo Abbey in Grottaferrata plus some
public fountains. This aqueduct is still perfectly working
Estimation of genetic parameters for height using spatial analysis in Tsuga heterophylla full-sibling family trials in British Columbia
Non-spatial and spatial analyses were carried out to study the effects on genetic parameters in ten-year height growth data across two series of 10 large second-generation full-sib progeny trials of western hemlock [Tsuga heterophylla (Raf.) Sarg.] in British Columbia. To account for different and complex patterns of environmental heterogeneity, spatial single trial analyses were conducted using an individual-tree mixed model with a two-dimensional smoothing surface with tensor product of B-spline bases. The spatial single trial analysis, in all cases, showed sizeable lower Deviance Information Criterion values relative to the non-spatial analysis. Also, fitting a surface displayed a consistent reduction in the posterior mean as well as a decrease in the standard deviations of error variance, no appreciable changes in the additive variance, an increase of individual narrow-sense heritability, and accuracy of breeding values. The tensor product of cubic basis functions of B-spline based on a mixed model framework does provide a useful new alternative to model different and complex patterns of spatial variability within sites in forest genetic trials. Individual narrow-sense heritabilities estimates from the spatial single trial analyses were low (average of 0.06), but typical of this species. Estimated dominance relative to additive variances were unstable across sites (from 0.00 to 1.59). The implications of these estimations will be discussed with respect to the western hemlock genetic improvement program in British Columbia.Fil: Cappa, Eduardo Pablo.
