Physical demands during 3×3 international male and female basketball games are partially impacted by competition phase but not game outcome

2021

Despite the increased popularity and number of international competitions for 3 × 3 basketball, the precise physical demands of this sport are not well described. Therefore, this study aimed to quantify the physical demands of 3 × 3 basketball games according to game outcome and competition phase. Following an observational design, video footage from 27 games were analysed from 104 international 3 × 3 basketball players (n = 52 male and n = 52 female players) belonging to 26 national teams (n = 13 male and n = 13 female teams) during the 2019 FIBA 3 × 3 World Cup. Manual frame-by-frame time-motion analyses were conducted to determine the relative frequency (n · min−1) and duration (% of liv…

Efecto de un programa de intervención sobre el estrés percibido, autoestima y rendimiento en jóvenes pilotos de motociclismo de elite

2013

En la especialidad deportiva de motociclismo la literatura científica se ha centrado en aspectos tecnológicos, de seguridad, incluso patrones de lesiones, existiendo poca información sobre variables psicológicas de los deportistas. El objetivo de nuestro estudio fue evaluar si el efecto de una intervención en habilidades técnicas y condición física sobre la percepción de estrés, autoestima, la autovaloración, la valoración de otros, y finalmente la ejecución. La muestra estuvo compuesto por 27 pilotos jóvenes de élite, participantes del Red Bull Moto GP Rookies Cup, de los cuales 16 sujetos realizaron un programa de intervención (Grupo Experimental, GE), mientras que el resto fue el Grupo C…

La Fallida Implantación de las Evaluaciones Externas con Propósitos de Certificación en el Sistema Educativo Español

2017

Resumen En Espana, en la ultima reforma de 2013 de la Ley educativa –esto es, en la LOMCE-, se establecieron pruebas externas estandarizadas con una gran trascendencia academica para el alumnado y que recientemente han sido dejadas sin efecto por el Gobierno, incluso antes de llegar a ser aplicadas. A lo largo del presente articulo defendemos que estas evaluaciones externas con proposito de certificacion y que han generado un enorme debate, si se hubiesen llegado a implementar, lejos de haber logrado mejorar la calidad del sistema educativo, lo que habrian conseguido es condicionar de forma muy negativa el proceso de ensenanza-aprendizaje, disminuyendo la calidad del aprendizaje del alumnad…

On thermoeconomics of energy systems at variable load conditions: integrated optimization of plant design and operation

2007

Abstract Thermoeconomics has been assuming a growing role among the disciplines oriented to the analysis of energy systems, its different methodologies allowing solution of problems in the fields of cost accounting, plant design optimisation and diagnostic of malfunctions. However, the thermoeconomic methodologies as such are particularly appropriate to analyse large industrial systems at steady or quasi-steady operation, but they can be hardly applied to small to medium scale units operating in unsteady conditions to cover a variable energy demand. In this paper, the fundamentals of thermoeconomics for systems operated at variable load are discussed, examining the cost formation process an…

THE ECONOMIC VALUE OF THE EXTERNALITIES ASSOCIATED WITH CULTURAL GOODS

2001

This study examined the economic value of the externalities associated with cultural goods. The purpose of this study is to clarify the willingness to pay to maintain the Central Finland museum of the ones which had filled a 18 year of Jyväskylä inhabitants and of factors which affect a payment willingness. From dichotomous choice valuation (DC-method) data we have estimated the cumulative probability density function (cdf). From estimated cdf we can calculate welfare measures such as median of the estimated distribution of CV. The study found firstly that the surplus of the consumer is thus 1.17 MFIM measured on the basis of the median value. In the respondents' opinion the value of the C…

The Self-expression Motivational System

2016

The main aim of this chapter is to introduce and promote the concept of self-expression as a basic motivation. Considering that the amount of literature on self-expression, matched with the concepts of control and affiliation, is practically non-existent, the chapter starts by attempting to provide a viable definition of self-expression motivation. Furthermore, the concept of art as a domain in which the underlying tendency for self-expression is clearly manifested is also considered. The chapter also includes a literature review to show whether or not self-expression motivation is able to fulfil the criteria suggested by Baumeister and Leary (Psychological Bulletin, 117, 497–529, 1995). Th…

Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

2019

Detrimental microbes caused the evolution of a great diversity of antimicrobial defenses in plants and animals. Insects developing underground seem particularly threatened. Here we show that the eggs of a solitary digger wasp, the European beewolf Philanthus triangulum, emit large amounts of gaseous nitric oxide (NO⋅) to protect themselves and their provisions, paralyzed honeybees, against mold fungi. We provide evidence that a NO-synthase (NOS) is involved in the generation of the extraordinary concentrations of nitrogen radicals in brood cells (~1500 ppm NO⋅ and its oxidation product NO2⋅). Sequencing of the beewolf NOS gene revealed no conspicuous differences to related species. However,…

A systematic review on external ear melanoma

2014

Summary Background External ear melanoma accounts for only 1% of all cutaneous melanomas, and data on its optimal management and prognosis are limited. Aim We aim to review the literature on external ear melanoma to guide surgeons in the treatment of this uncommon and peculiar pathology. Materials and methods A systematic review of English language studies on ear melanoma published from 1993 to 2013 was performed using the PubMed electronic database. Data on epidemiology, oncological treatment (tumor resection and regional lymph nodes management), and reconstruction were extrapolated from selected papers. Results The total number of patients was 858 (30 studies). The helix was the most comm…

Hydraulic power and control system

2020

Abstract In recent years, there has been worldwide interest in the improvement of the mobility of people with lower-limb amputation. Despite significant developments in new technologies during the last decade, commercial below-knee and above-knee prostheses are still energetically passive devices. However, many locomotive functions, like walking up stairs and slopes, need significant power in the knee and ankle joints. The additional power for doing previously mentioned activities needs to be achieved by means of external energy sources, which should be integral prosthetic components. In this chapter the design and development of the hydraulic power and control system are described.
