Solidarietà post-coniugale, assegno di divorzio e autonomia privata
2021
Il saggio esamina la questione dell'assegno di divorzio nella prospettiva della solidarietà post-coniugale, analizzando criticamente l'esito di cripto-indissolubilità del matrimonio che emerge dalla consolidata lettura della relativa obbligazione come tendenzialmente priva di termine finale. The essay examines the issue of the divorce allowance from the perspective of post-marital solidarity, critically analyzing the outcome of the crypto-indissolubility of marriage that emerges from the consolidated reading of the relative obligation as tendentially without a final term.
Preparation and physico-chemical study of inclusion complexes between idebenone and modified beta-cyclodextrins
1996
The inclusion properties of modifiedβ-cyclodextrins (trimethyl-β-cyclodextrin, dimethyl-β-cyclodextrin and hydroxypropyl-β-cyclodextrin) towards idebenone were compared with naturalβ-cyclodextrin. The inclusion complexes were prepared by different methods (coprecipitation, kneading, and freeze-drying) and characterized by differential scanning calorimetry, X-ray diffractometry, UV, CD and NMR spectroscopy. The results obtained by CD and NMR spectroscopy indicate a different orientation of idebenone in dimethyl-β-cyclodextrin with respect to other cyclodextrins. Stability constants of the complexes were determined in water at various temperatures and consequently thermodynamic parameters wer…
Nano-Silica Carriers Coated by Chloramphenicol: Synthesis, Characterization, and Grinding Trial as a Way to Improve the Release Profile
2022
Silica nanoparticles were applied as the carrier of chloramphenicol (2,2-dichloro-N-[(1R,2R)-1,3-dihydroxy-1-(4-nitrophenyl)propan-2-yl]acetamide), and were loaded in a 1% carbopol-based gel (poly(acrylic acid)), which allowed obtainment of an upgraded drug form. The samples of silica materials were obtained by means of modified Stöber synthesis, and their morphological properties were analyzed using Fourier transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) method, elemental analysis (EA), thermogravimetric analysis (TGA), analysis of the specific surface properties, X-ray diffraction study (XRD), scanning electron microscope (SEM), and dynamic light scattering (DLS) meth…
Pāra attiecību kvalitātes saistība ar konfliktu risināšanas stiliem sievietēm un vīriešiem
2021
Pētījuma mērķis bija izpētīt, vai pastāv saistība starp pāra attiecību kvalitāti un konfliktu risināšanas stiliem pāra attiecībās sievietēm un vīriešiem. Izpētē piedalījās 96 respondenti vecumā no 25 – 35 gadiem, iedalot sieviešu (n=66; SD=2,93) un vīriešu (n=30; SD=2,30) grupu. Pētījums ir neeksperimentāls, korelatīvi aprakstošs. Instrumentārijs iekļauj divas aptaujas: Uztvertās attiecību kvalitātes komponentu aptauja (Perceived Ralationship Quality Components, PRQC, Fletcher, Simpson & Thomas, 2000); Romantisko partneru konfliktu skala (The Romantic Partner Conflict Scale, Zacchilli, Hendrick, & Hendrick, 2009). No iegūtajiem datiem izriet statistiski nozīmīgas pozitīvas un negatīvas kore…
Studies of network structure and dynamics of e-beam crosslinked PVPs: From macro to nano
2011
Much interest has been paid to develop a variety of radiation-crosslinked hydrated polymeric materials, which swell in water but do not dissolve, as biocompatible materials used for wound healing, drug delivery system, surface-coating material for medically used devices, etc. With the aim of establishing design rules to produce hydrogels of controlled size at the nanoscale and desired internal network structure using conventional electron accelerators and set-ups, here we attempt a description in terms of structural and dynamic properties of polymer networks generated through e-beam irradiation of aqueous solutions of the same model polymer, a commercial grade poly(N-vinyl-pyrrolidone), sub…
Integrin-mediated entry of echovirus 1
2008
Paula Upla selvitti väitöskirjassaan echovirus 1:n solunsisäistä reittiä ja tunnisti solurakenteita ja säätelijöitä, jotka ovat tärkeitä infektiossa. Echovirus 1 (EV1) kuuluu pikornavirusperheeseen, jonka muita tunnettuja edustajia ovat poliovirus sekä karjan suu- ja sorkkatautivirus. EV1 on pieni (25-30 nm), vaipaton RNA-virus. EV1 aiheuttaa useimmiten oireettomia tai vähäoireisia suolisto- ja hengitystieinfektioita, mutta myös vakavampia tiloja, kuten aivokalvontulehdusta.Upla seurasi viruksen tunkeutumista soluun käyttäen elektronimikroskopiaa sekä tehokasta kolmi- ja neliulotteista konfokaalimikroskopiaa. Näin hän pystyi havainnoimaan yhtä aikaa usean eri molekyylin vuorovaikutusta niih…

Consistency of Targeted Metatranscriptomics and Morphological Characterization of Phytoplankton Communities
2020
The composition of phytoplankton community is the basis for environmental monitoring and assessment of the ecological status of aquatic ecosystems. Community composition studies of phytoplankton have been based on time-consuming and expertise-demanding light microscopy analyses. Molecular methods have the potential to replace microscopy, but the high copy number variation of ribosomal genes and the lack of universal primers for simultaneous amplification of prokaryotic and eukaryotic genes complicate data interpretation. In this study, we used our previously developed directional primer-independent high-throughput sequencing (HTS) approach to analyze 16S and 18S rRNA community structures. C…
Resolución de problemas en el área lógico-matemática aplicando la robótica educativa en Educación Infantil: una revisión sistemática
2020
La sociedad está en continuo cambio y, con ello, surgen nuevas metodologías en el ámbito escolar con el fin de que los alumnos adquieran habilidades que puedan ser útiles para su vida cotidiana. El objetivo de esta revisión sistemática es comprobar si el uso de la Robótica Educativa (RE) en Educación Infantil contribuye al desarrollo del pensamiento computacional de los niños y niñas, en concreto, si sirve como herramienta para la resolución de problemas. Tras realizar la búsqueda de literatura en Trobes+, Dialnet, PyscInfo, ERIC y Psicodoc, se incluyen 6 estudios en la revisión sistemática. Los resultados muestran una mejora en el pensamiento computacional de los estudiantes, el cual inclu…
Resolución de PAEV aditivos de cambio y de combinación en 1º de Primaria. Análisis comparativo con alumnos con Altas Capacidades.
2015
En el estudio que aquí se presenta, realizamos un análisis comparativo entre alumnos con altas capacidades o talento matemático y el resto de alumnado, en 1º de Primaria, durante la resolución de problemas aritméticos de estructura aditiva a partir de la modelización matemática. Con la información cualitativa extraída pretendemos determinar si el maestro puede llegar a detectar posibles casos de estudiantes con altas capacidades o talento gracias a las características comunes observadas entre los miembros de este colectivo al resolver problemas. In the study presented here, we carry out a comparative analysis among students with high abilities or mathematical talent and the rest of students…
