Asthma, allergies and respiratory symptoms in different activity groups of swimmers exercising in swimming halls
2021
Abstract Background Respiratory symptoms are common in competitive swimmers. However, among these and in swimmers at other activity levels the swimming distance, the total spent time in swimming halls and their medical background varies. Our objectives were, first, to assess their medical histories and the associations with respiratory symptoms among swimmers in different activity groups and then second, to study the pulmonary function findings and related medications in competitive swimmers who exercise in swimming hall environments the most. Methods First, 1118 participants consisting of 133 competitive-, 734 fitness- and 251 occasional swimmers answered questionnaires concerning their me…
Dark spatial solitary waves in a cubic-quintic-septimal nonlinear medium
2017
We consider the evolution of light beams in nonlinear media exhibiting nonlinearities up to the seventh order wherein the beam propagation is governed by the cubic-quintic-septimal nonlinear Schr\"odinger equation. An exact analytic solution that describes dark solitary wave propagation is obtained, based on a special ansatz. Unlike the well-known $\text{tanh}$-profile dark soliton in Kerr media, the present one has a functional form given in terms of ``${\text{sech}}^{2/3}$''. The requirements concerning the optical material parameters for the existence of this localized structure are discussed. This propagating solitary wave exists due to a balance among diffraction, cubic, quintic, and s…
Perhosuinnin lajianalyysi ja valmennuksen ohjelmointi: esimerkki huippu-urheilijasta – Jere Hård
2012
Tässä työssä tarkoituksena on perehtyä perhosuinnin tekniikkaan ja kilpauimarin harjoitteluun sekä altaassa että tukiharjoittelussa altaan ulkopuolella. Lisäksi tarkastelun kohteena ovat psykologiset tekijät ja kilpailutaktiikat. Työn alussa käsitellään lyhyen matkan perhosuinnin valmennuksellisia yleisiä linjoja, jonka jälkeen niiden pohjalta syvennytään lyhyen matkan huippu-uimarin Jere Hårdin menestyksekkääseen uintikauteen 2002. Perhosuinti on yksi neljästä uintimuodosta kilpauinnissa. Vapaauinnin jälkeen perhosuinti on toiseksi nopein uintimuoto. Perhosuinnin käsiveto koostuu viidestä vaihees-ta: veteentulo-, otteenhaku-, sisäänpyyhkäisy-, ylöspyyhkäisy- ja palautusvaihe. Yhden käsived…
«Prendere ad esempio». Quando padri e figli sono innamorati (con una lettura di Sen. contr. ii 6)
2018
This paper investigates the theme of erotic rivalry between father and son in Roman declamation, particularly in Ps. Quint. decl. 356, Calp. decl. 37 and, especially, in Sen. contr. ii 6. The analysis emphasizes the decisive contribution of the comedy to outlining this kind of conflict, also interpreted according to Quintilian’s theoretical reflection on this scholastica materia.
Lines on the Dwork pencil of quintic threefolds
2012
We present an explicit parametrization of the families of lines of the Dwork pencil of quintic threefolds. This gives rise to isomorphic curves which parametrize the lines. These curves are 125:1 covers of certain genus six curves. These genus six curves are first presented as curves in P^1*P^1 that have three nodes. It is natural to blow up P^1*P^1 in the three points corresponding to the nodes in order to produce smooth curves. The result of blowing up P^1*P^1 in three points is the quintic del Pezzo surface dP_5, whose automorphism group is the permutation group S_5, which is also a symmetry of the pair of genus six curves. The subgroup A_5, of even permutations, is an automorphism of ea…
Mirror quintics, discrete symmetries and Shioda maps
2008
In a recent paper, Doran, Greene and Judes considered one parameter families of quintic threefolds with finite symmetry groups. A surprising result was that each of these six families has the same Picard Fuchs equation associated to the holomorphic 3-form. In this paper we give an easy argument, involving the family of Mirror Quintics, which implies this result. Using a construction due to Shioda, we also relate certain quotients of these one parameter families to the family of Mirror Quintics. Our constructions generalize to degree n Calabi Yau varieties in (n-1)-dimensional projective space.
Regulating pre-performance psychobiosocial states with music
2016
The present study aimed to investigate the effects of music on swimmers’ pre-performance psychobiosocial states. We involved a purposeful sample of competitive swimmers (N = 17) in a 5-week intervention grounded in the individual zones of optimal functional (IZOF) model. Multiple findings were revealed. The first showed that pre-performance psychobiosocial states were predictive of subsequent performance. This was revealed by a high number of significant differences found between best and worst performance across modalities. Second, swimmers improved their ability to regulate pre-performance states through the use of music. This was shown through evidence that no significant differences wer…
Music and Medicine
2020
The relationship between music and medicine involves the notions of affinity between the human body and musical structures, relief, catharsis and therapy. The Homeric poems attest to the use of healing songs (paeans) and spells (epaoidai). The early Pythagoreans used musical catharsis for both the soul and the body. The doctrine of musical ēthos (whose main source is Plato) presupposes a relationship between music and character based on mimēsis, also establishing a link between therapy and ēthos. According to Aristotle, melodies performed in the rites are able to arou-se the emotions and purify from their excesses (the same dynamics appear in Theophrastus). The musical notions first detecta…
Differences between young children’s actual, self-perceived and parent-perceived aquatic skills
2021
As drowning is a leading cause of unintentional injury/death in children worldwide, perceptions of their actual aquatic skills are of critical importance. Children’s self-perceptions may influence the risks they take, and parental perceptions may influence the degree of supervision deemed to be necessary for children in and around water. Accordingly, we examined the differences between young children’s actual, self-perceived and parent-perceived aquatic skills. Using a three-way repeated measures ANCOVA, we analyzed data from 134 child-parent dyads (56.0% boys; M age = 7.1, SD = 1.1 years; and 71.6% mothers). We measured self and parental perceptions of the child’s aquatic skills with the …
Sulle tracce di Ovidio epico? Contese tra padri e figli in Ps. Quint. decl. 258
2018
In the Minor Declamation 258 it is possible to notice some echoes of the Armorum iudicium of Ov. met. xiii 1-383, an episode whose success in Greece and Rome dates back to the Cyclic poems. Porcius Latro, the famous rhetorician and teacher of Ovid, chose this subject for one of his declamations and provided his pupil with a model: in fact, as showed by Sen. contr. ii 2, 8, the poet borrowed from the rhetor some literal expressions. We can also remember Sen. contr. x and Calp. decl. 21, two of the most important texts where the motifs of family disputes and reward for viri fortes are re-elaborated, in different ages. Therefore, the Minor declamation 258 is one of these interesting adaptation…
