Photoinduced Electron Transfer between Ruthenium-bipyridyl Complex and Methylviologen in Suspensions of Smectite Clays
We examined photoinduced electron transfer (PET) in multicomponent
aqueous suspensions composed of tris(2,2′-bipyridine)ruthenium(II)
(Ru(bpy)<sub>3</sub><sup>2+</sup>, photocatalyst), methylviologen
(1,1′-dimethyl-4,4′-bipyridinium dication, MV<sup>2+</sup>, electron acceptor), and ethylenediamine tetraacetate (EDTA, sacrificial
electron donor) together with particles of smectite-type clays although
previous studies indicated inhibition of the electron transfer from
Ru(bpy)<sub>3</sub><sup>2+</sup> to MV<sup>2+</sup> in the presence
of clay particles. Clays with different lateral particle sizes were
compared: hectorite (Hect) and saponite (Sapo) with small particle
sizes (∼30 nm) and fluorohectorite (FH) and montmorillonite
(Mont) with large particle sizes (>0.1 μm). Clay particles
were
flocculated and were settled in many cases after the addition of Ru(bpy)<sub>3</sub><sup>2+</sup>, MV<sup>2+</sup>, and EDTA species, and the
Ru(bpy)<sub>3</sub><sup>2+</sup> and MV<sup>2+</sup> cations were
almost all adsorbed on the clay particles. When Hect and Sapo were
used, reduction of MV<sup>2+</sup> was observed on the aggregated
clay particles upon visible light irradiation indicating the occurrence
of PET from Ru(bpy)<sub>3</sub><sup>2+</sup> to MV<sup>2+</sup>. However,
the reaction was not observed for the samples where the clay particles
were not settled. When FH and Mont were used, PET was not observed
irrespective of the flocculation of clay particles. These results
demonstrated that PET from Ru(bpy)<sub>3</sub><sup>2+</sup> to MV<sup>2+</sup> in the presence of clay particles is possible when the clay
particles with small sizes are appropriately aggregated to allow interparticle
electron hopping

Collision detection on transmission lines with optical interferometer
V diplomski nalogi skušamo ugotoviti, v kolikšni meri je možno zaznavati in klasificirati trke na jeklenicah daljnovodov z optičnim interferometrom. Na začetku predstavimo osnovne pojme interferometrije in opišemo uporabljen optični interferometer. V jedru diplomske naloge natančneje opišemo eksperimentalni protokol in obdelavo signalov. Nadaljujemo z implementacijo algoritmov za segmentacijo in klasifikacijo zajetih signalov ter predstavimo dobljene rezultate. Segmentacijo izvedemo v domeni števila prehodov signala skozi ničlo, za klasifikacijo pa uporabimo večplastno nevronsko mrežo z algoritmom vzvratnega učenja. Rezultati študije nakazujejo, da sta implementirani segmentacija in klasifikacija uspešni v 77 % izvedenih trkov različnih predmetov.We analyse feasibility of collision detection on transmission lines with optical interferometer. We first provide a brief introduction into interferometry, along with a description of the optical interferometer used for measurements in this study. Afterwards, we describe the conducted experimental protocol and signal processing methodology. The focus is on implementation of algorithms for signal segmentation and collision classification. We used zero-crossing algorithm to transform signals into segmentation domain. Classification of collisions is done with a multilayer neural network trained by the backpropagation algorithm. The results demonstrate an average success rate of 77% for segmentation and classification of collision with five different objects
Sistematización de la experiencia de un ambiente de aprendizaje enriquecido por TIC durante la práctica clínica en fisioterapia cardiopulmonar en un hospital de nivel II de la ciudad de Cali
Esta investigación se centra en la caracterización de la experiencia de 4 estudiantes de fisioterapia de IX semestre de la Institución Universitaria Escuela Nacional del Deporte (IUEND) durante la implementación de un ambiente de aprendizaje enriquecido con Tecnologías de la Información y la Comunicación (TIC) en la práctica clínico – asistencial en Salud Cardiopulmonar; la cual se fundamenta en el hacer y pone a prueba las bases conceptuales del ciclo de fundamentación; todo esto con el fin de identificar las experiencias significativas que facilitan el aprendizaje y desarrollo de competencias clínicas, además analizar si este tipo de estrategias de enseñanza -aprendizaje permite al estudiante y al docente asesor superar inconvenientes propios de la práctica clínica como: optimizar tiempos de atención a pacientes, estudio independiente y trabajo colaborativo, retomar e integrar gran cantidad de conceptos y procedimientos aprendidos en IV semestre con las nuevas experiencias y la realidad del paciente; y a la vez cumplir con funciones administrativas propios del rol del fisioterapeuta asistencial (estadística, indicadores, desarrollo de guías, etc.) que dificultan el proceso de aprendizaje; concluyendo que los ambientes mediados por TIC pueden lograr superar estas dificultades y favorecer finalmente el aprendizaje significativo (juicio clínico), en el que se fundamenta el ciclo de práctica profesional
