Microscopic and nanoscopic EVA composite investigation: Electrical properties and effect of purification treatment
2004
This work presents preliminary results of an investigation aiming at characterization of nanocomposite insulating materials. Focus is made on size and technological process effects, i.e. dependence of electrical properties on filler size, on polymer-nanofiller interaction (e.g. intercalation or exfoliation) and, in particular, on chemical purification procedures. The materials under investigation are (EVA) copolymer filled by layered micro and nanosized silicates consisting of montmorillonite and fluorohectorite, that is, natural and synthetic clays. Microstructural characterization, using transmission electron microscopy, TEM, and wide-angle X-ray spectroscopy, WAXS, and electrical measure…
Guardia y custodia compartida impuesta
2018
Cuando una pareja con hijos comunes menores de edad deja de convivir surge la necesidad de determinar las reglas o normas por las que se regirá la nueva situación familiar. Estas normas pueden ser de carácter económico o personal. Entre las personales, y una sobre las que más les cuesta decidir a los progenitores, es la relativa al cuidado de los hijos y a cómo se va a dar continuidad a las relaciones con ellos una vez se haya producido la separación. Lo mejor sería que los propios progenitores pudieran llegar a un acuerdo al respecto ya que ellos son los que mejor conocen a sus hijos y los mejores conocedores de la situación que están viniendo. Pero en defecto de acuerdo será necesario det…
Consumer Information Services in Intercultural Tourism : An Ethnographic Study of Chinese Outbound Backpackers
2017
This paper reports the findings of an ethnographic study of Chinese outbound backpackers’ use and adoption of consumer information services (CIS) in an intercultural tourism setting. We apply McKenna et al.’s research model of consumers’ adoption of information services as the analytical lens for the interpretive qualitative study. The data gathering was conducted in four different countries. The findings of the study confirm linkages between four information service types and the use and adoption of CIS. The study also found that service types are more diversely linked than the earlier studies have predicted and therefore we propose a revised research model, which can be used for studying …
Assessment and strengthening of reinforced concrete bridges with half-joint deterioration
2022
Existing Niagara-type concrete cantilever bridges, which in Italy are called Gerber bridges, suffer from degradation due to reinforcement corrosion and a consequent reduced load-bearing capacity. The assessment of these structures is therefore an important part of the procedures for analyzing the state of existing bridges and any interventions required for their retrofitting. In particular, safety against failure of the half-joint must be evaluated with respect to the behavior of the entire bridge and its state of conservation, determining what the conditions are that lead to failure, in terms of loads, state of stress, and possibly cracking state. This evaluation has to be carried out cons…
Speed control of the V2 skating technique in elite cross-country skiers
2016
The aim was to examine how skiers control skiing speed using V2-skating. Subjects skied with three submaximal and maximal speeds on 100 m 4° uphill. Cycle variables and force parameters form the arms and legs were analysed. Cycle rate increased up to the maximum speed. Cycle length increased from the slowest speed to the all other speeds. Pole force and delta leg force increased up to the maximum speed. Ranges of motions and angular velocities of kick flexion and extension with knee and hip joints increased till highest submaximal speed. Speed was regulated with cycle length and rate while the latter was dominant after ∼5.0 m/s. Higher speed was reached with higher forces from arms and leg…
Non-uniformity of displacement and strain within the Achilles tendon is affected by joint angle configuration and differential muscle loading.
2020
Although the Achilles tendon (AT) has been studied for more than a century, a complete understanding of the mechanical and functional consequences of AT structural organization is currently lacking. The aim of this study was to assess how joint angle configuration affects subtendon displacement and strain of soleus (SOL) and lateral gastrocnemius (LG) muscles. Knots sutured onto SOL and LG subtendons of 12 Wistar rats, were videotaped to quantify displacements and the ankle torque was assessed for different isometric activation conditions (i.e., individual and simultaneous) of the triceps surae muscles. Changing ankle and knee joint angle affected the magnitude of displacement, relative dis…
Teologiczny dialog rzymskokatolicko-prawosławny: stan i perspektywy
2018
Roman Catholic-Orthodox dialogue, due to the doctrinal similitude of both ecclesial traditions, raises the greatest hopes as to unification in faith and in church teachings. Over nearly four hundred years of work by the Joint Commission for the theological dialogue between the Roman Catholic Church and the Orthodox Church on the global scene, it has born much good fruit. For the dialogue to be initiated, the Churches had to pass through enormous transformation, both mental and spiritual. The point was for them to rediscover each other as sisterly Churches. Establishing Joint Commission for the theological dialogue between the Roman Catholic Church and the Orthodox Church (November 30,1979) …

Dzīves kvalitāte pacientiem pirms gūžas locītavas endoprotezēšanas
2020
Bakalaura darba tēma '' Dzīves kvalitāte pacientiem pirms gūžas locītavas endoprotezēšanas''. Tēmas aktualitāti nosaka tas, ka ik gadu pieaug rindā stāvošo cilvēku skaits, kam nepieciešama gūžas locītavas endoprotezēšana. Šis augošais skaitlis parāda to, ka problēma ir aktuāla gan jaunu pacientu, gan gados vecāku cilvēku grupā. Darba mērķis: Noskaidrot pacientu dzīves kvalitāti pirms gūžās locītavas endoprotezēšanas. Pētījuma jautājums: Kāda ir dzīves kvalitāte pacientiem pirms gūžas locītavas endoprotezēšanas? Pētījuma metode: Kvalitatīvā pētījuma metode, pētījuma instruments - intervijas jautājumi. Pētījums tika veikts X slimnīcā, tajā piedalījās 20 pacienti pirms plānveida gūžas locītava…
Validity and Reliability of a New Optoelectronic System for Measuring Active Range of Motion of Upper Limb Joints in Asymptomatic and Symptomatic Sub…
2019
The aim of this study was to evaluate the validity of the Veloflex infrared dynamic angle-meter (Veloflex-IDA) and the intra- and inter-rater reliability when measuring the ranges of motion (ROMs) of the upper limb joints. Thirty-five healthy and 20 symptomatic participants were evaluated. Twelve upper limb movements were measured in two sessions with the Veloflex-IDA, which is a device composed of a camera that tracks the trajectory of retro-reflective markers. In addition, a goniometer was used in the first session to evaluate concurrent validity. Validity and agreement were evaluated by Pearson correlation coefficient (r) and Bland&ndash
