Deguna vārsta kustīguma kvantitatīvs novērtējums
2018
Pamatojums: Deguna vārsts ir visšaurākais reģions visos augšējos elpceļos. Tā ir kustīgā deguna daļa, kas tiek uzskatīta par STARLING-rezistoru. Lai paplašinātu vai stabilizētu deguna vārstu, ir publicētas dažādas palīgierīces un metodes, taču indikācijas to izmantošanai ir balstītas vien uz ķirurgu personīgo pieredzi. Mērķis: Veikt objektīvu deguna vārsta lomas novērtējumu. Materiāli un metodes: Pētījumā tika iekļauti 30 brīvprātīgie, kuriem ar elastīgu tērauda elementu, fiksētu pie galvas lentes un aprīkotu ar deformācijas sensoru (strain gauge), tika precīzi izmērīta deguna laterālās sienas novirze tās dziļākajā punktā elpošanas laikā. Novirzes kalibrācija tika veikta ar speciālām kalibr…
Search for magnetically-induced signatures in the arrival directions of ultra-high-energy cosmic rays measured at the Pierre Auger Observatory
2020
We search for signals of magnetically-induced effects in the arrival directions of ultra-high-energy cosmic rays detected at the Pierre Auger Observatory. We apply two different methods. One is a search for sets of events that show a correlation between their arrival direction and the inverse of their energy, which would be expected if they come from the same point-like source, they have the same electric charge and their deflection is relatively small and coherent. We refer to these sets of events as "multiplets". The second method, called "thrust", is a principal axis analysis aimed to detect the elongated patterns in a region of interest. We study the sensitivity of both methods using a …
Causal and Non-Causal Frequency Domain Assessment of Spontaneous Baroreflex Sensitivity after Myocardial Infarction
2020
Acute myocardial infarction (AMI) is thought to alter the baroreflex control of arterial pressure. We tested this hypothesis investigating the changes of the cardiovascular response after AMI in comparison with young and old healthy controls studied at rest and during head-up tilt, using causal and non-causal frequency domain measures of the baroreflex sensitivity. Our results indicate: (i) the importance of using a causal approach that takes into account not only feedback but also feedforward effects in the study of interactions between the heart period and the arterial pressure; (ii) the compromised capacity of baroreceptors to control SAP fluctuations in post-AMI patients, both at rest a…
Métodos de entrenamiento de fuerza alternativos para incrementar la activación muscular en ejercicios de empuje
2016
Introducción. Los movimientos en los que se empuja o presiona con los brazos a una resistencia externa constituyen un elemento clásico dentro de los programas de entrenamiento de la fuerza. Tradicionalmente se han empleado ejercicios convencionales con pesos libres y máquinas con los que se conseguía alcanzar intensidades de activación muscular altas. Sin embargo, tratando de incrementar en mayor medida la intensidad en este tipo de ejercicios, durante los últimos años se han comenzado a utilizar nuevos medios y métodos alternativos (por ejemplo utilizando dispositivos de suspensión, resistencia elástica o tratando de activar músculos de forma selectiva). No obstante, es escasa la evidencia…
Steering of a Sub-GeV electron beam through planar channeling enhanced by rechanneling
2014
We report the observation of efficient steering of a 855 MeV electron beam at MAMI (MAinzer MIkrotron) facilities by means of planar channeling and volume reflection in a bent silicon crystal. A $30.5\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ thick plate of (211) oriented Si was bent to cause quasimosaic deformation of the (111) crystallographic planes, which were used for coherent interaction with the electron beam. The experimental results are analogous to those recorded some years ago at energy higher than 100 GeV, which is the only comparable study to date. Monte Carlo simulations demonstrated that rechanneling plays a considerable role in a particle's dynamics and hinders the spoiling…
Behavioral and psychological flexibility in eating regulation among overweight adults
2016
Weight-loss programs are often based on self-control techniques and they commonly fail in long-term weight management. Identifying psychological processes that explain eating behaviors can help to develop more effective interventions for long-term weight management. This research examined how behavioral and psychological flexibility are related to eating regulation and weight management in overweight adults. The first goal was to study the effects of flexible vs. rigid restraint of eating on weight-loss maintenance and well-being. The second goal was to examine whether psychological flexibility and mindfulness, independently and together, explain intuitive eating regulation. The third goal …
Ikääntyvien lonkkamurtumapotilaiden toimijuus ja elämäntilanteet
2011
Pro gradu -tutkimuksessani tutkin yli 60-vuotiaiden lonkkamurtumapotilaiden elämäntilannetta ja kuntoutuskokemuksia toimijuusnäkökulmasta. Tutkimukseni teoreettisen viitekehyksen muodostavat Anthony Giddensin strukturaatioteorian tarkastelu yhdessä Jyrki Jyrkämän toimijuusviitekehyksen eri ulottuvuuksien, kuten elämänkulku, pakot, välttämättömyydet, esteet ja mahdollisuudet ja tulevaisuuden odotukset – kanssa. Tutkimuksessani haastattelin Keski-Suomen eri kunnissa asuneita seitsemää (7) ikääntyvää naista, joilla jokaisella oli ollut lonkkamurtuma. Tavoitteena oli selvittää haastattelujen avulla, millaista toimintakykyä ja toimijuutta sekä tulevaisuuden odotuksia lonkkamurtumapotilaalla eläm…
Lo zerosei di fronte all’emergenza COVID. Esperienze, ricerche e riflessioni pedagogiche
2022
Il volume prende le mosse da un incontro on line organizzato il 28 novembre 2020 dal Gruppo SIPED Infanzia sul tema: Lo zero-sei di fronte all’emergenza COVID. In quella sede vennero proposte riflessioni particolarmente interessanti, che hanno trovato poi un approfondimento scientifico nei diversi contributi raccolti. È suddiviso in tre parti tra loro interrelate, che spaziano temporalmente dall’improvvisa chiusura totale dei servizi per l’infanzia a marzo 2020, fino alle prime esperienze di riapertura in nuovi assetti organizzativi nell’a.s. 2020-21. La situazione pandemica e le sue conseguenze pratiche, hanno generato criticità gestionali, oltre a preoccupazione e disorientamento nel pers…
Relaciones entre neurocognición, procesamiento emocional y funcionamiento social en la esquizofrenia
2017
Resumen: En la esquizofrenia se presentan una serie de déficits cognitivos que han hecho que la investigación y la práctica profesional actual se centren en el estudio de la neurocognición y la cognición social. Estos déficits tienen importantes implicaciones en el funcionamiento social. El objetivo del presente trabajo es analizar la relaciones entre neurocognición, cognición social, evaluada con tareas de reconocimiento de la emoción, y funcionamiento social. Sesenta personas con diagnóstico de esquizofrenia han formado la muestra y las áreas evaluadas han sido: funcionamiento ejecutivo y flexibilidad cognitiva, atención y vigilancia, memoria, velocidad de procesamiento, identificación y …
