In vivo triceps surae and quadriceps femoris muscle function in a squat jump and counter movement jump
2000
An optic fibre method was used to measure in humans in vivo Achilles (ATF) and patellar tendon forces (PTF) during submaximal squat jumps (SJ) and counter movement jumps (CMJ). Normal two-legged jumps on a force plate and one-legged jumps on a sledge apparatus were made by four volunteers. Kinetics, kinematics, and muscle activity from seven muscles were recorded. The loading patterns of the tendomuscular system differed among the jumping conditions, but were similar when the jumping height was varied. Peak PTF were greater than ATF in each condition. In contrast to earlier simulation studies it was observed that tendomuscular force could continue to increase during the shortening of muscle…
THE ADMINISTRATIVE JUSTICE IN SPAIN: CURRENT SITUATION AND CHALLENGES
2016
Since the Spanish Constitution of 1978 there has been a full and effective administrative justice. The citizens have the possibility to request a judicial review of decisions taken by the public Administrations, while being either the owners of a subjective right or of a legitimate interest. The interim judicial protection is not limited to the suppression of the act or general provision and the Courts are invested with direct powers to enforce their sentences. However, different problematic issues about the inactivity of the public Administrations and the enforcement of sentences are the new challenges to ensure the administrative justice. To this it must be added that there are problems r…
Using Private Social Care Services in Finland : Free or Forced Choices for Older People?
2016
Use of private social care services among older people is increasing in Finland. This study aims to understand why older people choose private care in a comprehensive tax-subsidized social care system and examines whether people choose private service as a free choice or a forced choice as well as what factors contribute toward making these choices. Data for this study (N = 1,436) were gathered in 2010 from people aged 75 and above living independently at home in two Finnish cities: Tampere and Jyväskylä. Data were analyzed with several quantitative tests: chi-squared tests, multinomial regression analysis, and qualitative content analysis (for the open-ended responses from the survey quest…
Alignment of contact center workforce management implementation with research and ITIL version 3
2010
The purpose of this research is to theoretically validate three contact center workforce management processes models against both the previous research and the ITIL framework version 3. The three models are about processes themselves, processes implementation, and processes and tools implementation together. The research has been conducted in a constructive way. First, the three models that have been used in real-life are described, the relevant ITIL and workforce management research are summarized, and the ITIL framework service lifecycle is explained on the level it is needed. Then, the models are first compared against the ITIL framework and then against the summarized research. The most…
Explicit proton transfer in classical molecular dynamics simulations.
2014
We present Hydrogen Dynamics (HYDYN), a method that allows explicit proton transfer in classical force field molecular dynamics simulations at thermodynamic equilibrium. HYDYN reproduces the characteristic properties of the excess proton in water, from the special pair dance, to the continuous fluctuation between the limiting Eigen and Zundel complexes, and the water reorientation beyond the first solvation layer. Advantages of HYDYN with respect to existing methods are computational efficiency, microscopic reversibility, and easy parameterization for any force field peerReviewed
A control strategy based on intelligent algorithm (PSO) to perform electrical stimulation systems
2017
International audience; Adjusting stimulation parameters using control strategy based on reliable mathematical model that can predict perfectly the muscle response, may improve the efficiency of Functional Electrical Stimulation (FES) systems. In the present project, we investigate the PID control tuning based on the Particle Swarm Optimization (PSO) algorithm at the first time in neuro-muscular systems for updating automatically the stimulation pulse amplitude to track a desired force profiles. In the beginning, The PSO algorithm is used to identify unknown force model parameters. Next, optimal PID gains are found by the same intelligent algorithm to improve the control system. The obtaine…
Intramolecular Hydrogen Bond, Hirshfeld Analysis, AIM; DFT Studies of Pyran-2,4-dione Derivatives
2021
Intra and intermolecular interactions found in the developed crystals of the synthesized py-ron-2,4-dione derivatives play crucial rules in the molecular conformations and crystal stabili-ties, respectively. In this regard, Hirshfeld calculations were used to quantitatively analyze the different intermolecular interactions in the crystal structures of some functionalized py-ran-2,4-dione derivatives. The X-ray structure of pyran-2,4-dione derivative namely (3E,3′E)-3,3′-((ethane-1,2-diylbis(azanediyl))bis(phenylmethanylylidene))bis(6-phenyl-2H-pyran-2,4(3H)-dione) was determined. It crystallized in the monoclinic crystal system and C2/c space group with unit cell parameters: a = 14.0869(4) …
Medial Gastrocnemius Muscle Architecture Is Altered After Exhaustive Stretch-Shortening Cycle Exercise
2019
Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle architecture is affected by this type of exercise. This study investigated potential changes in medial gastrocnemius (MG) muscle architecture after exhaustive stretch-shortening cycle exercise. Male athletes (n = 10) performed maximal voluntary contractions (MVC) and maximal drop jump (DJ) tests before and after an exercise task consisting of 100 maximal DJs followed by successive rebound jumping to 70% of the initial maximal height. The exerci…
Estudio sobre parámetros mecánicos y distancia de golpeo de Bandal Chagui de Taekwondo
2009
En este estudio se analizan los parámetros mecánicos fuerza de impacto (FI), tiempo de reacción (TR), tiempo de movimiento (TM), tiempo total de respuesta (TT) y dominancia, en la patada circular o Bandal Chagui en Taekwondo, basado en la regulación de la distancia de golpeo (ED1, ED2 y ED3).

Proteins in Ionic Liquids: Reactions, Applications, and Futures
2019
Biopolymer processing and handling is greatly facilitated by the use of ionic liquids, given the increased solubility, and in some cases, structural stability imparted to these molecules. Focussing on proteins, we highlight here not just the key drivers behind protein-ionic liquid interactions that facilitate these functionalities, but address relevant current and potential applications of protein-ionic liquid interactions, including areas of future interest.
