Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems
2020
Peat-free growing media constituents and stand-alone substrates are the basis for the economic and ecological efficiency of the soilless culture system. Nevertheless, divergence between the model and practice still exists, coming from large gaps in the knowledge of alternative organic materials and of their effects on crop performance. A more detailed understanding of these topics is necessary to increase the soilless culture management capacity. In this respect, this critical review collects research outcomes concerning the sustainability of soilless culture and growing media constituents and their impact on the environment. In particular, the review covers designated articles stressing th…
Low Tree Vigor, Free Palmette Training Form, and High Planting Density Increase Olive and Oil Yield Efficiency in Dry, Sloping Areas of Mediterranean…
2022
Exploiting biodiversity must be considered today an effective strategy to improve the sustainability of olive production systems. The evaluation of local cultivars, based on their vegetative and fruiting traits, along with an analysis of product quality, may contribute significantly to the development and diffusion of new olive-growing systems. The aim of this study was to evaluate growth, productivity, and olive oil quality of three Sicilian cultivars with different vigor/growth habit grown in four different combinations of training form and planting density. ‘Abunara’, ‘Calatina’, and ‘Nocellara del Belice’ olive trees were planted in four different int…
Tiše edešʹ dalʹše budešʹ glazami Polâkov
2020
This article is devoted to the analysis of the use of the Russian proverb by Polish Internet users: ”We’re getting it done, slowly but surely”. The analysis showed that the authors of the statements know the origin of this proverb, but misunderstand its meaning, which is caused by an interlanguage homonymy.
The effects of instructional self-talk on quiet eye duration and golf putting performance
2017
Yonatan Sarig, 2017. The Effects of Instructional Self-Talk on Quiet Eye Duration and Performance. Faculty of Sports and Health Science. University of Jyväskylä. Master’s thesis, 63p. While the literature on the effects of instructional self-talk is comprehensive, a somewhat under-investigated subject is the underlying mechanisms of instructional self-talk. As of late, the trend has been shifted towards researching what are the motivational and attentional constructs at the base of self-talk. Potentially, one such attentional construct is the quiet eye; the final gaze fixation on a target before the execution of task-oriented movement. Since the duration of the quiet eye is found to be asso…

Predicting the 2000‐m Rowing Ergometer Performance from Anthropometric, Maximal Oxygen Uptake and 60‐s Mean Power Variables in National Level Young R…
2020
Abstract Many studies reported various relationships between 2000-m rowing performance and anthropometric as well as metabolic variables, however, little is known about 60-s mean power in elite youth athletes. The aim of this study was to develop different regression models to predict 2000-m rowing indoor performance time (t2000) using anthropometric variables, maximal oxygen uptake (VO2max) and mean power established during a 60-s all-out test (W60) in national elite youth rowers. Fifteen youth male Italian rowers (age: 15.7 ± 2.0 years; body height: 176.0 ± 8.0 cm; body mass: 71.2 ± 10.0 kg) performed an incremental maximal test, a 60-s all-out test and a 2000-m race simulation using a Co…
Specialized Movement on the Rowing Ergometer and Post-workout Changes in Selected Peripheral Blood Parameters – a Case Report.
2018
Rowing is a sport discipline, which requires extreme physical strength and endurance and appropriate aerobic and anaerobic capacity as well. However, when the workout intensity and load is very high, exercise is associated with temporary changes in cellular metabolism and the immune system. The study included one male rower aged 28 years – the highly-skilled and experienced athlete. We determined basic cardiorespiratory fitness measures, complete blood count, and 24 clinical chemistry parameters including relevant biochemical and haematological parameters and matrix metaloproteinases activities. Maximal exercise on the rowing ergometer induced 2-fold increase in absolute counts of all leuko…
Modificazioni posturali indotte dal canottaggio in giovani atleti ben allenati
2005
This research brings evidence that rowing represents a valid sports model for helping both healthy and paramorphic people in changing unhealthy back positions. In particular, this study analyzed the changes induced to the back of twenty well trained athletes. Furthermore, it was taken into consideration a case of an athlete who presented a case of kyphosis and lordosys. This study was carried on for a period of two years during which it was observed that both kyphosis and lordosys had disappeared in the subject observed for this study. The quantitative and qualitative variables taken into account here, demonstrate that the positive results for correcting and self-correcting the position of …

2022
The chapter is part of the book "Wood in Sport Equipment - heritage, present, perspective". It is focused on the use of wood in two sports included in Olympics program: rowing and flatwater.
Collisional Relaxation Processes Studied by Coherent Raman Spectroscopy for Major Species Present in Combustions
1992
The effects of collisional relaxation processes on the Q-branch profile of major species present in combustions have been studied by high resolution stimulated Raman spectroscopy. Particular interest has focused on the following collisional systems: N2-N2, O2-O2, CO2-CO2, O2-N2, N2-CO2 and N2-H2O. For each colliding pair, starting from accurate determinations of line broadening coefficients over a wide temperature range, state-to-state rates for rotational energy transfers have been deduced by using various fitting laws. Among these rate laws, special attention has been paid to the temperature dependence of the energy corrected scaling (ECS) law combined with a hybrid exponential-power law …
