25 años de graffiti en Valencia: aspectos sociológicos y estéticos

2015

La Tesis Doctoral "25 Años de Graffiti en Valencia: Aspectos Sociológicos y Estéticos" es un estudio que pone en valor todo el espectro de las escenas de graffiti y creatividad pública independiente -Street Art- de la ciudad de Valencia. El marco teórico del estudio son los Estudios Culturales, Subculturales y Postsubculturales. La metodología específica de su abordaje es la Observación Participante. El estudio se inicia con el análisis de los precedentes visuales, actitudinales y estratégicos de las prácticas del graffiti y la creatividad pública independiente: el cómic, el cartoon animado, la cultura popular, el cine, la televisión,la rotulación comercial, el diseño gráfico y la contracul…

Tejidos para la divina muerte. Los sudarios pintados con retrato y escenas religiosas del Egipto romano

2015

El estudio de las creencias funerarias de tradición egipcia en época de dominación romana ha sido el objeto principal de la presente tesis doctoral. En el antiguo Egipto, como en otras culturas antiguas y modernas, los difuntos eran ataviados con objetos que garantizaban una plácida existencia ultraterrena. Ajuares que suponen testimonios importantes de la identidad personal de los difuntos y su sociedad, sobre todo en lo concerniente a su religiosidad. Para conocer un poco más las mencionadas creencias y prácticas mortuorias se eligieron aquellos materiales que mayor información podían ofrecer al respecto, en términos cuantitativos y cualitativos: sudarios pintados con retratos centrales r…

Diversity at the nanoscale : laser-oxidation of single-layer graphene affects Fmoc-phenylalanine surface-mediated self-assembly

2023

We report the effects of a laser-oxidized single layer graphene (SLG) surface on the self-assembly of amphiphilic gelator N-fluorenylmethoxycarbonyl-L-phenylalanine (Fmoc-Phe) towards an gel–SLG interface. Laser oxidation modulates the levels of hydrophobicity/hydrophilicity on the SLG surface. Atomic force, scanning electron, helium ion and scattering scanning nearfield optical microscopies (AFM, SEM, HIM, s-SNOM) were employed to assess the effects of surface properties on the secondary and tertiary organization of the formed Fmoc-Phe fibres at the SLG–gel interface. S-SNOM shows sheet-like secondary structures on both hydrophobic/hydrophilic areas of SLG and helical or disordered structu…

Vuorokaudenajan ja harjoitusjärjestyksen vaikutukset hermostolliseen adaptaatioon, lihasvoimaan ja poikkipinta-alaan yhdistetyssä voima- ja kestävyys…

Rytkönen, Tuomas (2015). Vuorokaudenajan ja harjoitusjärjestyksen vaikutukset hermostolliseen adaptaatioon, lihasvoimaan ja poikkipinta-alaan yhdistetyssä voima- ja kestävyysharjoittelussa. Liikuntabiologian laitos, Jyväskylän yliopisto. Valmennus- ja testausopin pro gradu -työ. 91 s. Monissa liikuntasuoritteissa tarvitaan sekä voimaa (V) että kestävyyttä (K). Yhdistetyssä V+K -harjoittelussa kohtuullinen harjoittelun kokonaisvolyymi on avain siihen, että voiman kehittyminen häiriintyy mahdollisimman vähän kestävyysharjoittelusta. Tässä tutkimuksessa V:aa ja K:ttä harjoitettiin 2–2,5 kertaa viikossa. Yksi aikaa säästävä tapa toteuttaa yhdistettyä V+K -harjoittelua on harjoittaa V:aa ja K:tt…

Experimental studies on carbon nanotubes and graphene functionalized via physical adsorption with cellulose and avidin

2018

In this Thesis I have experimentally studied structural, electronic, and optical properties of hybrids of nanocarbon materials, carbon nanotubes (CNT) and graphene, and certain biomacromolecules. The latter are especially xylan, a type of hemicellulose, and avidin, an important protein. Complexes of CNT with hemicellulose are attractive because the hybrid material is soluble in water. The conductive transport properties of thin films of CNT /hemicellulose have been systematically studied with different experimental tools. These are low temperature DC conduction measurements, Kelvin probe microscopy, and optical conductivity measurements at terahertz frequencies. The results clearly indicate …

Unraveling the prominent role of the Rh/ZrO2-interface in the water-gas shift reaction via a first principles microkinetic study

2018

The industrially important water–gas-shift (WGS) reaction is a complex network of competing elementary reactions in which the catalyst is a multicomponent system consisting of distinct domains. Herein, we have combined density functional theory calculations with microkinetic modeling to explore the active phase, kinetics, and reaction mechanism of the WGS over the Rh–ZrO2 interface. We have explicitly considered the support and metal and their interface and find that the Rh–ZrO2 interface is far more active toward WGS than Rh(111) facets, which are susceptible to CO poisoning. CO2 forming on the zirconia support rapidly transforms into formate. These findings demonstrate the central role of…

The role of oxidation treatments before and after CVD synthesis of graphene on copper catalytic surface

2021

Graphene is a sheet of honeycomb bonded carbon, that is only one atom thick. Aside from its remarkable strength, graphene has great conducting and photochemical prop erties. Due to its unique properties, it can be used as viable option for rare metals in circuits and in new type of measuring components. To express these properties at their best, graphene should be single crystal and as clean as possible. In this bachelor thesis, different treatment options for catalytic metal surface for graphene synthesis are studied in chemical vapor deposition growth. Different options to treat the catalytic metal layer were studied, such as changes in gas compositions in annealing process, electropolish…

Occurrence of pharmaceuticals in municipal wastewater treatment plants and receiving surface waters in Central and Southern Finland

2016

The presence of five selected pharmaceuticals, four anti-inflammatory drugs, diclofenac, ibuprofen, ketoprofen, naproxen, and an antiepileptic drug carbamazepine, was determined at four municipal wastewater treatment plants (WWTPs) and in the receiving waterway near the city of Jyväskylä, in central Finland and also in the River Vantaa. First, an analytical method was developed including a pretreatment and purification followed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in the multiple reaction monitoring mode. The studied pharmaceuticals were detected from influents and effluents of four municipal WWTPs and from surface water of eight locations along the water …
