Kriptovalūtas kā noziedzīga nodarījuma instruments, to tiesiskais regulējums un problemātika
2018
Jebkuras veiksmīgas valūtas pamatfunkcijas ir maksājumu nodrošināšana, kalpošana par uzskaites un uzkrāšanas vienību. Šī ir fundamentāla naudas pastāvēšanas teorija. Virtuālās valūtas pastāvēšana ir balstīta uz decentralizētu datortīklu. Virtuālās valūtas emisiju un darījumus ar virtuālo valūtu neuzrauga ne centrālā banka, ne kāda institūcija vai komercbanka – tiek uzskatīts, ka virtuālā valūta “sevi regulē pati”. Kriptovalūtas regulējuma trūkums un anonimitātes iespējamības rada būtiskus riskus noziedzīga nodarījuma izdarīšanai, izmantojot virtuālo valūtu kā noziedzīga nodarījuma instrumentu, kas var apdraudēt valsts un sabiedrības intereses. Autors šajā darbā pēta virtuālās valūtas (kript…
Evaluation of ergonomics and efficacy of instruments in dentistry
2013
Abstract: Purpose: To evaluate the ergonomics and efficacy of five instruments used in dentistry for scaling and root planing. Methods: This experimental study with a comparative cross-sectional design was carried out during a simulated scaling and root planing task. Seven female dentists and one dental hygienist aged 26–58 years participated. Five instruments were evaluated in a subjective analysis of usability and musculoskeletal strain and with measurements of muscular activity, postures of the upper limbs, and work productivity. Results: The instruments with the thickest (diameter of 12–14 mm) silicon handles caused the lowest perceived strain in both the fingers/palm and the thumb. Wor…
¿Música o magia? La presentación de las ondas musicales de Maurice Martenot en España
2015
On 1928, the French musician Maurice Martenot presented at Paris Opera a new electronic musical instrument which he called musical waves. It had success like only a few and attracted the interest of the composers, Martenot strove to spread it with a initial tour that took it all around the world between 1931 and 1932. From the information given by the press –because there are not more references– this article aims to rebuild the presentation of the instrument in Spain all along 1932, to report about the reception by the review and to justify the mystery that involved the instrument because of its unknown electronic running and its performance only with the hands movement on the air.En 1928,…
La plantilla 3.0, un instrumento para conocer la música de la infancia: Revisión y validación
2015
Este trabajo se interesa por conocer la música de la vida diaria de los niños desde una mirada educativa1. Para estudiarlo el artículo ofrece un instrumento que permite conocer los elementos objetivos de la música que escuchan, prestando especial atención al entorno sonoro de mayor cobertura e impacto, el mediático. El instrumento constituye el paso inicial para estudiar los posibles efectos de la música y proponer alternativas educativas, porque la finalidad última de la investigación es la mejora de la educación. El desarrollo metodológico ha consistido en la creación del instrumento, la plantilla 3.0, y su aplicación, dando cuenta en este artículo de su revisión, características técnicas…
Jurisdiction in cases of divorce, legal separation or marriage annulment
2021
The subject of coordination is fundamental for the functioning of jurisdictional rules of the Regulation n.2016/1103 on matrimonial property regimes and Regulation n.2016/1104 on the property consequences of registered partnerships. Both Property Regimes Regulations have the purpose of gathering litigation before the courts of one Member State and have the related procedures managed by the courts of the same Member State. Recital 34 of Regulation No. 2016/1103 specifies that matters of matrimonial property regime related to proceedings pending before the court of a member state hearing an application for divorce, legal separation or marriage annulment should be dealt with by the courts of t…

Analysis of high-frequency rotational angioplasty-induced echo contrast.
1991
During high-frequency rotational angioplasty (HFRA), myocardial contrast enhancement (echo contrast) was observed by means of two-dimensional echocardiography. In order to evaluate the echo contrast produced by HFRA, an in vitro experimental model was built using a cylinder with the HFRA catheter scanned in a water bath. The cylinder was filled with blood, mineral water, and distilled water. With a 2.5-MHz transducer, echograms were recorded and analyzed by video intensitometer, and the maximum intensity IUmax and persistence time P were calculated. Rotation frequencies of 20,000-200,000 rpm with 2.0--mm burrs and times of 10 s were tested. In another model, hyperbaric conditions for the sa…

Pediatric oncologic endosurgery.
2017
Despite increasing popularity of minimal-invasive techniques in the pediatric population, their use in diagnosis and management of pediatric malignancy is still debated. Moreover, there is limited evidence to clarify this controversy due to low incidence of each individual type of pediatric tumor, huge diversity of the disease entity, heterogeneity of surgical technique, and lack of well-designed studies on pediatric oncologic minimal-invasive surgery. However, a rapid development of medical instruments and technologies accelerated the current trend toward less invasive surgery, including oncologic endosurgery. The aim of this article is to review current literatures about the application o…
