METODI DI STUDIO DELLA VARIABILITA’ DELLA FREQUENZA CARDIACA
2010
La frequenza cardiaca (FC) è controllata dal sistema nervoso vegetativo. Il nodo senoatriale (SA) ha una frequenza propria di depolarizzazione spontanea conosciuta come “frequenza intrinseca” che rappresenta la frequenza misurata in assenza di impulsi simpatici o parasimpatici come si può ottenere con la denervazione o il blocco farmacologico. Nei soggetti normali la frequenza intrinseca è di circa 100 bpm e dipende dal sesso e dall’età ed è influenzata dall’esercizio fisico, l’ipossia e le variazioni di temperatura. I soggetti allenati a sport di resistenza hanno una frequenza intrinseca minore. Gli effetti del sistema simpatico e parasimpatico influenzano in maniera predominante la FC int…
SVILUPPO DI METODOLOGIE DI PROGETTAZIONE INTEGRATA PER BARCHE A VELA DA COMPETIZIONE
2021
In questo lavoro di tesi sono presi in esame i metodi di progettazione integrata con riferimento al disegno nautico delle piccole imbarcazioni a vela da competizione. La progettazione di una barca a vela, in tutte le sue parti, è un processo molto complesso in quanto richiede una profonda esperienza in questo campo ed inoltre necessita di diverse competenze dal punto di vista tecnico in aree anche molto distanti tra loro. Nella vita di tutti i giorni spesso risolviamo problemi relativamente semplici e quindi troviamo la soluzione anche in modo intuitivo, in ingegneria solitamente si affrontano problemi un po’ più complessi e seguire una procedura strutturata aiuta molto per trovare soluzion…
Bērna radošā pašizpausme vizuālajā mākslā pirmsskolā
2021
Grāmata paredzēta topošajiem skolotājiem studiju kursam Kultūras izpratnes un pašizpausmes mākslā mācību jomas saturs un mācīšanās pieejas: vizuālās mākslas metodika un praktizējošiem pirmsskolas skolotājiem, bērnu vecākiem. Grāmata palīdzēs skolotājam mērķtiecīgi organizēt pašizpausmes procesu vizuālajā mākslā, lai bērnam veidotos vispārīgās jeb caurviju prasmes, kas ietver bērna darbības kognitīvos, emocionālos un sociālos aspektus, kuri palīdz apgūt zināšanas, izpratni un pamatprasmes cilvēka darbībai nozīmīgās jomās. Grāmatas autore ir LU Pedagoģijas, psiholoģijas un mākslas fakultātes docētāja.
Skolēna radošuma sekmēšana un vērtēšana
2020
Grāmata paredzēta studentiem, topošajiem skolotājiem. Piedāvātais materiāls potenciāli būs noderīgs ikvienā metodikas kursā pamatizglītības skolotāju programmās, lai mērķtiecīgi organizētu skolēnu radošuma un līdz ar to caurviju prasmju – jaunrades un uzņēmējspējas, kritiskās domāšanas un problēmu risināšanas, kā arī pašvadītas mācīšanās – attīstību dažādās izglītības jomās. E-grāmata tapusi ar Latvijas Universitātes Pedagoģijas, psiholoģijas un mākslas fakultātes projekta “Inovatīvo e-mācību grāmatu un videofilmu izstrāde jaunajām izglītības, pedagoģijas un sporta virziena studiju programmām” atbalstu.
Jēgpilns mācību process vizuālajā mākslā
2020
Grāmata paredzēta studentiem, topošajiem skolotājiem, apgūstot studiju kursu “Kultūras izpratnes un pašizpausmes mākslā mācību jomas saturs un mācīšanās pieejas: Vizuālās mākslas metodika”, kā arī praktizējošiem skolotājiem. Grāmata palīdzēs mērķtiecīgi organizēt vizuālās mākslas nodarbības, lai skolēns, mācoties vizuālo mākslu bez pratības kultūras izpratnē un pašizpausmē mākslā, gūtu pašvadītas mācīšanās, kritiskas domāšanas un problēmu risināšanas, jaunrades, sadarbības un pilsoniskās līdzdalības pieredzi, pilnveidojot caurviju prasmes. Grāmatā vizuālā māksla uztverta nevis kā mērķis, bet gan kā līdzeklis daudzveidīgu personisku, sociālu un kulturālu mērķu sasniegšanai.
Relationship between Wingate test and vertical jump in young female volleyball players
2016
Aims: Maximum vertical jump is an important component in performing spike and block skill in volleyball and is a reflection of explosive muscle strength(Bosco et al. 1983). The Wingate test (WT is used to evaluate anaerobic performance by measuring muscle power during short-term, high-intensity exercise(Bar-Or 1987). The aim of this study was twofold: to investigate the possible relationship between power performance on the Wingate test (WT) and explosive leg strength performed during a vertical counter-movement jump test(CMJ) and whether anaerobic power assessed could identify players with the best performance. Methods: 14 young female volleyball players, age 16–26 years, were grouped by p…

A thermodynamically consistent cohesive-frictional interface model for mixed mode delamination
2016
Abstract A new interface constitutive model based on damage mechanics and frictional plasticity is presented. The model is thermodynamically consistent, it is able to accurately reproduce arbitrary mixed mode debonding conditions and it is proved that the separation work is always bounded between the fracture energy in mode I and the fracture energy in mode II. Analytical results are given for proportional loading paths and for two non-proportional loading paths, confirming the correct behavior of the model for complex loading histories. Numerical and analytical solutions are compared for three classical delamination tests and frictional effects on 4ENF are also considered.
Seasonal Changes in physiological parameters in young club level rowers
2013
Aims: To evaluate variations in biometrics, physiological and performance parameters over a seasonal training – from September to March - in club level young rowers. Methods: Six young rowers, age 13-15, affiliated with a rowing club member of the Italian Rowing Federation, were assessed three times at regular three-months intervals (September, December, and March) during the 2011 season. Biometrics evaluations included stature, body mass and body composition, whereas physiological assessments on rowing ergometer included maximum oxygen uptake (VO2max) obtained during an incremental test, and average power output values obtained during a 2000m trial (W2000) and during a 20-sec (W20) and a 6…
Effect of internal noise on the relaxation time of an yttria stabilized zirconia-based memristor
2022
The effects of temperature on the switching kinetics of an yttrium-stabilized zirconia-based memristor from a low-resistance state to a high-resistance state have been experimentally investigated. It was found that the memristor relaxation time depends on the temperature in a non-monotonous way, with a maximum observed at the temperature close to 55 °C. This nonmonotonic behavior is a signature of the noise-enhanced stability phenomenon observed in all physical and complex systems characterized by metastable states.
