Video Viewing Patterns Using Different Teaching Treatments: A Case Study Using YouTube Analytics
2019
Aquest estudi explora els patrons de visualització de 17 vídeos en un context tradicional daprenentatge i en un context de classe invertida per 723 estudiants de negocis cursant un mòdul relacionat amb . Mentre recerques anteriors s?han centrat principalment en resultats (per exemple, satisfacció/resultats dels alumnes), en aquest estudi l?enfocament recau en com la natura de les interaccions del estudiants amb el vídeos por determinar-se mitjançant un anàlisi profund de les dades analítiques. Els nostres resultats mostren menys interacció amb els vídeos en el context de la classe invertida que en el de la classe tradicional. De la mateixa manera, mostren un ús més elevat dels vídeos com a …

The impact of the EMA change in definition of "dose" on the BCS dose-solubility ratio: a review of the biowaiver monographs.
2013
The Biopharmaceutics Classification System (BCS) defines the solubility characteristics of an active pharmaceutical substance based on its dose-solubility ratio: for highly soluble drugs this ratio is less than 250 mL over a defined pH range. Prior to the revision of the European Medicines Agency (EMA, formerly EMEA) guideline in 2010, the "dose" in this ratio was consistently defined by the US FDA, the EMA, and the WHO biowaiver guidelines as the highest dosage strength. However, in the revised EMA guideline, the dose is defined as the highest single dose administered according to the Summary of Product Characteristics. The new EMA criterion for highly soluble may be closer to the actual c…
Secondary hyperalgesia and perceptual wind-up following intradermal injection of capsaicin in humans.
1998
Wind-up and secondary hyperalgesia both are related to central sensitization, but whereas the former is explained by homosynaptic facilitation, the latter is due to heterosynaptic facilitation. To investigate possible interactions between both types of facilitation, we tested for alterations of perceptual wind-up in the secondary hyperalgesic skin zone adjacent to a capsaicin injection with light touch (by a cotton wisp) and punctate stimuli (calibrated von Frey hairs and pin pricks). Temporal summation of pain sensation (perceptual wind-up) was only observed with a clearly noxious stimulus (pin prick) presented at a repetition frequency of 0.6 s(-1), but not 0.2 s(-1). Pain ratings to trai…
Generalized hyperalgesia in patients with chronic tension-type headache.
2006
Increased pain sensitivity in the central nervous system may play an important role in the pathophysiology of chronic tension-type headache (CTTH). Previous studies using pain thresholds as a measure of central pain sensitivity have yielded inconsistent results and only a few studies have examined perception of muscle pain without involvement of adjacent tissues. It has been suggested that suprathreshold testing might be more sensitive than threshold measurements in evaluation of central hyperexcitability in CTTH. The aim of the study was to compare pain ratings to suprathreshold single and repetitive (2 Hz) electrical stimulation of muscle and skin in cephalic (temporal and trapezius) and…
How much Is needed? Comparison of the effectiveness of different pain education dosages in patients with fibromyalgia
2019
AbstractObjectiveTo assess the effect of different dosages of pain neuroscience education (PNE) programs on central nociceptive processing in patients with fibromyalgia. Second, to compare the effects of different dosages of PNE programs on numerical pain rating scale (NPRS), disability, and psychological variables.DesignSingle-blind randomized controlled trial.SettingThree fibromyalgia centers in Spain (Valencia, Alcorcón, Alcalá de Henares).SubjectsSeventy-seven patients with fibromyalgia.MethodsParticipants were randomized to four groups of PNE: 1) high-dose PNE (N = 20), 2) low–concentrated dose PNE (N = 20), 3) diluted low-dose PNE (N = 20), and (4) control treatment (N = 17), conducte…
European Resuscitation Council Guidelines 2021: Executive summary
2021
Abstract: Informed by a series of systematic reviews, scoping reviews and evidence updates from the International Liaison Committee on Resuscitation, the 2021 European Resuscitation Council Guidelines present the most up to date evidence-based guidelines for the practice of resuscitation across Europe. The guidelines cover the epidemiology of cardiac arrest; the role that systems play in saving lives, adult basic life support, adult advanced life support, resuscitation in special circumstances, post resuscitation care, first aid, neonatal life support, paediatric life support, ethics and education.
Note sull'embriologia nella tarda antichità e la prima età bizantina
2019
This paper deals with the outcomes of Galenism in Greek Late Antiquity and in the first period of the Byzantine era, considering particularly the rare but significant elements of novelty which are present in the rereading of the ancient tradition by John of Alexandria, in the Alexandrian Summaries of the Galenic Canon, and by Stephanus and Theophilus Protospatharius.
Krāsu kalibrēšanas algoritma izstrāde
2022
Darbs ir uzrakstīts latviešu valodā uz 24 lapaspusēm. Tas satur 16 attēlus, 4 pielikumus un 19 atsauces uz literatūras avotiem. Darba mērķis: Pārbaudīt un modificēt datoru monitoru krāsu kalibrēšanas algoritmu. Metode: Pētījumā tika izmantos NEC monitors, kuram tika noskaidroti esoša krāsu kalibrēšanas algoritma koeficienti un tika ierosināta šī algoritma modificēšana, t.sk. precīzi noskaidrotas lineārās sakarības starp katra krāsu kanāla X un Z integrālsummām un spožuma vērtībām. Rezultāti: Neviens no algoritmiem (standarta un modificēts) nenodrošina ideālu rezultātu, kā arī neviens no algoritmiem neuzrāda ka viens būtu labāks par otru.
