Enseñanza de las ciencias : revista de investigación y experiencias didácticas
(1) IB de Segorbe, (2) IB Sorolla, (3) CP Padre Manjon, (4) Facultad de Ciencias Fisicas, Valencia. SUMMARY We analyze how the basic concepts about atomic models are introduced into the Spanish educational system. We considered the textbooks most currently used in the educational levels from 8th EGB to the 1st University level. We finally discuss the possible sources of misconceptions. 1.
Experimental and CFD evaluation of ozone efficacy against coronavirus and enteric virus contamination on public transport surfaces
The limited information about the routes of the transmission of SARS-CoV-2 within the ongoing pandemic scenario mobilized the administration, industry and academy to develop sanitation and disinfection systems for public and private spaces. Ozone has been proposed as an effective disinfection method against enveloped and non-enveloped viruses, including viruses with similar morphology to SARS-CoV-2. Due to this efficacy, numerous gaseous and aqueous phase ozone applications have emerged potentially to inhibit virus persistence in aerosols, surfaces, and water. In this work, a numerical model, a RANS CFD model for ozone dispersion inside tram and underground coach has been developed includin…
RNA-binding properties and membrane insertion of Melon necrotic spot virus (MNSV) double gene block movement proteins
AbstractAdvances in structural and biochemical properties of carmovirus movement proteins (MPs) have only been obtained in p7 and p9 from Carnation mottle virus (CarMV). Alignment of carmovirus MPs revealed a low conservation of amino acid identity but interestingly, similarity was elevated in regions associated with the functional secondary structure elements reported for CarMV which were conserved in all studied proteins. Nevertheless, some differential features in relation with CarMV MPs were identified in those from Melon necrotic virus (MNSV) (p7A and p7B). p7A was a soluble non-sequence specific RNA-binding protein, but unlike CarMV p7, its central region alone could not account for t…
