Pirkstiņrotaļas un rotaļas ar priekšmetiem 3- 4 gadus vecu bērnu griešanas prasmes sekmēšanai
2019
Kvalifikācijas darba tēma ir, “Pirkstiņrotaļas un rotaļas ar priekšmetiem 3-4 gadus vecu bērnu griešanas prasmes sekmēšanai”. Darba mērķis ir teorētiski analizēt un praktiski pētīt, kā pirkstiņrotaļu un rotaļu ar priekšmetiem pielietošana sekmē 3-4 gadus vecu bērnu griešanas prasmes. Mērķa sasniegšanai tika izvirzīti vairāki uzdevumi: 1. Analizēt pedagogu un psihologu atziņas par 3-4 gadus vecu bērnu attīstību un raksturot griešanas prasmes. 2.Analizēt pedagogu atziņas par rotaļu, pirkstiņrotaļu pētījuma kontekstā. 3.Veikt pētījumu par griešanas prasmju sekmēšanu rotaļā. Darba pirmajā daļā teorētiski tiek analizēta pedagogu un psihologu atziņas par bērna attīstības īpatnībām vidējā pirmskol…
Three-dimensional crystallization of the light-harvesting complex from Mantoniella squamata (Prasinophyceae) requires an adequate purification proced…
1995
Abstract We present a new purification procedure for the light-harvesting complex of Mantoniella squamata whereupon three-dimensional crystallization succeeded. Previous purification methods were based on density centrifugations as the only separating principle. We have extended this preparation procedure by applying anion-exchange and molecular-sieve chromatography techniques. Purity and stability of the complex were proved by denaturing and non-denaturing polyacrylamide-gel electrophoresis, and spectroscopic measurements. With respect to contaminating lipids the purified pigment-protein complex was examined by thin-layer chromatography and the aggregation and/or oligomeric states were inv…
Sulle tracce di Proteo (Odissea 4, 382 ss). Tra memoria tecnica e psicologia della memoria
2023
In Odyssey, Book 4, Proteus, the old man of the sea, is represented as a divine figure in possess of peculiar skills: a prophetic art as well as a metamorphic one, which, full of tricks (dolìe techne), enables him to escape anyone who tries to capture him for knowing his/her own future, and this is properly the case of the Spartan king Menelaus. In this way, it emerges that the Proteus’ expertise, a technical one, depends on the methodic recalling to the memory of various morphological status, whose repeated seriality is the guarantee of being successful in changing his form continuously: the use of the expression “he (i.e. the old man) did not forget his tricky art” (v. 455) deserves consi…
SARS-CoV-2 vaccine response and rate of breakthrough infection in patients with hematological disorders
2022
Abstract Background The clinical efficacy of SARS-CoV-2 vaccines according to antibody response in immunosuppressed patients such as hematological patients has not yet been established. Patients and methods A prospective multicenter registry-based cohort study conducted from December 2020 to December 2021 by the Spanish transplant and cell therapy group was used to analyze the relationship of antibody response at 3–6 weeks after full vaccination (2 doses) with breakthrough SARS-CoV-2 infection in 1394 patients with hematological disorders. Results At a median follow-up of 165 days after complete immunization, 37 out of 1394 (2.6%) developed breakthrough SARS-CoV-2 infection at median of 77 …
The Greenland shark Somniosus microcephalus—Hemoglobins and ligand-binding properties
2017
A large amount of data is currently available on the adaptive mechanisms of polar bony fish hemoglobins, but structural information on those of cartilaginous species is scarce. This study presents the first characterisation of the hemoglobin system of one of the longest-living vertebrate species (392 +/- 120 years), the Arctic shark Somniosus microcephalus. Three major hemoglobins are found in its red blood cells and are made of two copies of the same a globin combined with two copies of three very similar beta subunits. The three hemoglobins show very similar oxygenation and carbonylation properties, which are unaffected by urea, a very important compound in marine elasmobranch physiology.…
Datu modeļa redaktora optimizācija
2016
Šajā dokumentā ir aprakstīts kvalifikācijas darbs „Datu modeļa redaktora optimizācija”. Datu modeļa redaktors ir rīks, kas tiek izmantots auto un mājokļu apdrošināšanas polišu tirdzniecības sistēmas Alfa izstrādē. Datu modeļa redaktora rīks izmantoja novecojušas javascript bibliotēkas un ielādēja visus struktūras elementus vienlaicīgi. Šī darba mērķis bija samazināt datu modeļa redaktora ielādes laiku. Mērķis tika sasniegts, izmantojot asinhronu datu ielādi – lietotājs ielādē elementus tikai tad, kad tie ir nepieciešami. Datu modeļa redaktors tika papildināts ar jaunu funkcionalitāti, kas atvieglo tā lietotāju darbu.
¿Cómo afecta la innovación en la satisfacción y la lealtad hacia el establecimiento minorista?
2021
Resumen En el presente estudio, se examinó el concepto de innovación en el sector minorista y se definieron sus relaciones con otras variables, como la satisfacción y la lealtad, tradicionalmente vinculadas con el establecimiento minorista. Para lograr los objetivos planteados, se delimitó un modelo teórico sustentado en la literatura, que se contrastó mediante un estudio empírico utilizando un cuestionario estructurado ad hoc aplicado a una muestra de 510 clientes de establecimientos de alimentación. El análisis de los datos se desarrolló mediante la técnica de regresión por mínimos cuadrados parciales. Los resultados permiten proponer un conjunto de recomendaciones para la gestión, fundam…
Cryo-EM structure of ssDNA bacteriophage ΦCjT23 provides insight into early virus evolution.
2022
AbstractThe origin of viruses remains an open question. While lack of detectable sequence similarity hampers the analysis of distantly related viruses, structural biology investigations of conserved capsid protein structures facilitate the study of distant evolutionary relationships. Here we characterize the lipid-containing ssDNA temperate bacteriophage ΦCjT23, which infects Flavobacterium sp. (Bacteroidetes). We report ΦCjT23-like sequences in the genome of strains belonging to several Flavobacterium species. The virion structure determined by cryogenic electron microscopy reveals similarities to members of the viral kingdom Bamfordvirae that currently consists solely of dsDNA viruses wit…
