The Experimental Study of Heat Waste Conversion into Useful Electric Power
2009
This paper presents the practical results ofthe design solutions, executing and experimentaltesting of a prototype model of o thermoelectricgenerator, based on the conversion of residualthermical energy into electric power, by improving theSeebeck effect. To this purpose, high performancethermoelectric modules have been used, taken from therecent production of the American Corporation Hi-ZTechnology. The prototype thermoelectric generatorbuilt for a demonstrative purposes has got the lowefficiency category. The results taken from the testsand experimental measurements have showntheimportance of the constructive solution of materialsand technologies that have been used. These resultsdirect t…
THE ATTITUDE AND MOTIVATION OF BUYERS OF TRADITIONAL/ LOCAL/ BIO PRODUCTS IN THE CONTEXT OF AGROTOURISM, IN SIBIU COUNTY, ROMANIA
2013
Based on the statistical data concerning the sheep breeding in district Sibiu and on the information obtained by making investigations markets and fairs where they sell traditional/bio products, the extent was appreciated to which this products are known and desired. The survey was conducted between May and November 2012 in four locations: “Transilvania Peasant Market (Piata Taraneasca Transilvania)”, “Traditional agro-food products Fear (Targul de Produse Agroalimentare Traditionale)” from Huet Market, “Traditional Products and Handicrafts Fear (Targul de Produse Traditionale si Mestesugaresti)” inside the Carrefour hypermarket and in “Agricultural Market” Rasinari, Sibiu county. There wer…
Reliability and Sensitivity of Nocturnal Heart Rate and Heart-Rate Variability in Monitoring Individual Responses to Training Load
2022
Purpose: To assess the reliability of nocturnal heart rate (HR) and HR variability (HRV) and to analyze the sensitivity of these markers to maximal endurance exercise. Methods: Recreational runners recorded nocturnal HR and HRV on nights after 2 identical low-intensity training sessions (n = 15) and on nights before and after a 3000-m running test (n = 23). Average HR, the natural logarithm of the root mean square of successive differences (LnRMSSD), and the natural logarithm of the high-frequency power (LnHF) were analyzed from a full night (FULL), a 4-hour (4H) segment starting 30 minutes after going to sleep, and morning value (MOR) based on the endpoint of the linear fit through all 5-m…
Water immersion methods do not alter muscle damage and inflammation biomarkers after high-intensity sprinting and jumping exercise
2020
Purpose The aim of this study was to compare the efficacy of three water immersion interventions performed after active recovery compared to active recovery only on the resolution of inflammation and markers of muscle damage post-exercise. Methods Nine physically active men (n = 9; age 20‒35 years) performed an intensive loading protocol, including maximal jumps and sprinting on four occasions. After each trial, one of three recovery interventions (10 min duration) was used in a random order: cold-water immersion (CWI, 10 °C), thermoneutral water immersion (TWI, 24 °C), contrast water therapy (CWT, alternately 10 °C and 38 °C). All of these methods were performed after an active recovery (1…
Rimboschimento e recupero di soprassuoli forestali artificiali degradati: due aspetti fondamentali per la salvaguardia del territorio montano - Refor…
2015
I fenomeni di dissesto del territorio che in questi ultimi anni sembrano acutizzarsi e recare ferite profonde in tutto il Paese, se da un lato sono quasi endemici data la morfologia e la natura dei terreni, certamente dall'altro sono frutto della mancanza di gestione pianificata e programmatica dell'uso del territorio. Ad esse si unisce il profondo mutamento del tessuto sociale e il conseguente abbandono di molte aree agricole e forestali divenute marginali all'attività economica, cui non ha fatto fronte una politica di salvaguardia del territorio efficace e duratura. Ai problemi di stabilità del territorio montano e collinare, spesso originati da inadeguate attività umane, si è fatto front…
Pandemia y reformas procesales: la incidencia del COVID-19 en el proceso labora
2020
Uno de los efectos de la declaración del estado de alarma por el COVID-19 fue la suspensión de las actividades judiciales. La reanudación de estas actividades implicaba una serie de nuevos retos (acumulación de trabajo; incremento de la litigiosidad; adopción de medidas de seguridad y salud). El RDL 16/2020, de 28 de abril, afrontó algunos de estos retos e introdujo modificaciones tanto en el desarrollo de la actividad judicial, como en la organización de sus recursos. Este trabajo trata de sistematizar tales medidas desde una perspectiva crítica.
Validating Habitual and Goal-Directed Decision-Making Performance Online in Healthy Older Adults
2021
Everyday decision-making is supported by a dual-system of control comprised of parallel goal-directed and habitual systems. Over the past decade, the two-stage Markov decision task has become popularized for its ability to dissociate between goal-directed and habitual decision-making. While a handful of studies have implemented decision-making tasks online, only one study has validated the task by comparing in-person and web-based performance on the two-stage task in children and young adults. To date, no study has validated the dissociation of goal-directed and habitual behaviors in older adults online. Here, we implemented and validated a web-based version of the two-stage Markov task usi…
Izmaiņas Latvijas piekrastes ainavā 20.-21. gadsimta mijā un mūsdienu izaicinājumi
2013
Dažādi faktori ietekmē piekrastes zonas attīstību gan pasaulē, gan Latvijā, kā rezultātā notiek izmaiņas ainavas struktūrā un tās spējā nodrošināt sabiedrībai nepieciešamos resursus. Promocijas darbā Latvijas piekrastes ainava ir pētīta atšķirīgos mērogos un kontekstos: i) izmaiņas jūras piekrastes ainavas struktūrā un tās ietekmējošie faktori ir vērtēti visas Latvijas piekrastes zonā; ii) potenciālā vēja enerģijas ražošanas jūrā ietekme uz ainavas vizuālo struktūru ir novērtēta unikālajā Baltijas jūras stāvkrastu zonā; iii) pludmales ainavas kā rekreācijas pakalpojuma nodrošinātāja nozīmīgums ir noskaidrots četrās atšķirīgās Latvijas pludmalēs. Darbs ir transdisciplinārs, jo tajā ir izmant…

Technologies have played a fundamental role as a tool during confinement, making the center website one of the main channels of communication with families and students and a place to share digital resources and other educational materials. Las webs escolares han pasado a ser uno de los principales canales comunicativos y principal fuente de recursos durante la pandemia
Clinical Onset and Multiple Sclerosis Relapse after SARS-CoV-2 Infection
2021
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been associated with several neurological disorders including headache, facial palsy, encephalitis, stroke, demyelinating disorders. The present report will discuss cases of multiple sclerosis (MS) onset and relapse both beginning early after SARS-CoV-2 infection. In both cases, magnetic resonance imaging (MRI) showed widespread bilateral subcortical and periventricular active lesions. Serum IgG against SARS-CoV-2 Spike antigens confirmed seroconversion with titers that are considered not definitely protective against possible reinfection. We hypothesize that SARS-CoV-2 infection, as previously reported for other vir…
