Sintonikas ietekme uz miopiju
2017
MĒRĶIS: noteikt sintonikas fototerapijas efektivitāti jauniešiem ar vidējās pakāpes miopiju līdz 3,0D vai nekoriģēto sākotnējo miopiju. METODE: 10 miopi vecumā no 8 līdz 17 gadi. Tika izmantotāss redzes asuma, miopijas pakāpes, akomodācijas amplitūdas, acs zīlītes αω reakcijas un redzes lauka noteikšanas testi. Pēc sākotnējās pārbaudēs dalībnieki tika pakļauti 15 sintonikas seansiem. REZULTĀTI: pēc sintonikas pielietošanas statistiski nozīmīgi uzlabojas akomodācijas amplitūda, redzes asums, acs zīlītes reakcijas - αω un redzes lauks. Tika novērots miopijas samazinājums3 dalībniekiem ar sākotnējo miopiju un nozīmīga uzlabošanas parējiem 4 dalībniekiem. SECINĀJUMI: Statistiski nozīmīgi rezult…
The Possibility of Performing Money Functions by Digital Currencies Illustrated With an Example of Bitcoin
2018
In this paper the considerations on possibility of performing money functions by digital currency with an example of bitcoin are presented. The conditions of bitcoin emerge and its spectacular dynamic development caused by limitations of contemporary financial system are being discussed. This paper introduced one of the most popular digital currencies — bitcoin in terms of three elementary economic functions of money: mean of exchange, measure of value and store of value.
Comparison between the MHFEM formulation and a 2nd spatial order FV formulation of the linear groundwater flow problem
2008
Mixed and Mixed Hybrid Finite Elements (MHFE) methods have been widely used in the last decade for simulation of groundwater flow problem, petroleum reservoir problems, potential flow problems, etc. The main advantage of these methods is that, unlike the classical Galerkin approach, they guarantee local and global mass balance, as well the flux continuity between inter-element sides. The simple shape of the control volume, where the mass conservation is satisfied, makes also easier to couple this technique with a Finite Volume technique in the time splitting approach for the solution of advection-dispersion problems. In the present paper a new second spatial approximation order Finite Volum…
First-Episode Psychotic Patients Showed Longitudinal Brain Changes Using fMRI With an Emotional Auditory Paradigm
2020
Most previous longitudinal studies of functional magnetic resonance imaging (fMRI) in first-episode psychosis (FEP) using cognitive paradigm task found an increased activation after antipsychotic medications. We designed an emotional auditory paradigm to explore brain activation during emotional and nonemotional word processing. This study aimed to analyze if longitudinal changes in brain fMRI BOLD activation is present in patients vs. healthy controls. A group of FEP patients (n = 34) received clinical assessment and had a fMRI scan at baseline and follow-up (average, 25-month interval). During the fMRI scan, both emotional and nonemotional words were presented as a block design. Results w…
Valorization of low value fisheries species in Sicily (Italy), by realization of functional food: a case study of high technological readiness level
2016
The growing demand for fish products of safe and local origin and the need to reduce fishing on target species, requires continuous diversification in the seafood industry, to meet the needs of consumers. One solution is represented by the use of surplus species of local fisheries, of little commercial value and often ignored by the consumer, which, if subjected to new preservation and processing methodologies, allow to create new product categories, which open up new market opportunities. In our study, we setup and applied, on some local surplus fisheries species from western Sicily, some processing technologies, aimed to valorize and extend the shelf life of fish products: the cold smokin…
Periodontal health in a population with Parkinson's disease in Spain: a cross-sectional study.
2022
Background: The aim of this research is to evaluate the periodontal health of patients with Parkinson Disease (PD) in a Spanish cohort. Material and Methods: A cross-sectional study was performed on 104 patients with PD (mean age: 66.19+9.3 years) and 106 controls (mean age: 59.26+14.11 years). A pre-designed clinical protocol was implemented, which included a standardized epidemiological index for periodontal disease (CPITN), clinical attachment loss (CAL), tooth-loss, full mouth plaque index (FMPI), and oral hygienic habits. Univariate descriptions and comparative analysis were performed. Results: The majority of PD patients presented good oral hygienic habits. There were no significant d…

Flexible Perfluoropolyethers-Functionalized CNTs-Based UHMWPE Composites: A Study on Hydrogen Evolution, Conductivity and Thermal Stability
2022
Flexible conductive composites based on ultra-high molecular weight polyethylene (UHMWPE) filled with multi-walled carbon nanotubes (CNTs) modified by perfluoropolyethers (PFPEs) were produced. The bonding of PFPE chains, added in 1:1 and 2:1 weight ratios, on CNTs influences the dispersion of nanotubes in the UHMWPE matrix due to the non-polar nature of the polymer, facilitating the formation of nanofillers-rich conductive pathways and improving composites’ electrical conductivity (two to five orders of magnitude more) in comparison to UHMWPE-based nanocomposites obtained with pristine CNTs. Electrochemical atomic force microscopy (EC-AFM) was used to evaluate the morphological changes dur…
