Mujeres zapatistas y producción videográfica en Chiapas
2018
Los primeros años de la rebelión zapatista coincidieron con la emergencia en México de un sector videográfico independiente, posibilitado por las nuevas tecnologías de grabación y edición, e inspirado en la lucha chiapaneca con sus redes de comunicación y solidaridad nacional e internacional. Antecediendo la era del Web 2.0 y las actuales redes sociales digitales, la producción videográfica sobre y desde el zapatismo fue una herramienta importante para la visibilización del conflicto y también de las transformaciones dentro de las comunidades chiapanecas, entre otras la autonomización y protagonismo de las mujeres. Este artículo explora la primera década de producción videográfica en torno …
Care and gendered work in reception centers in Finland
2019
PurposeThis paper focuses on how gendered processes of working life are (re)constructed and are also challenged discursively in paid and volunteer care and work in reception centers. The purpose of this paper is to show how caring work with asylum seekers can both enhance the traditional gender order and challenge it through enabling men to have opportunities to care.Design/methodology/approachThe data were produced through qualitative interviews among paid workers and volunteers in reception centers, and analyzed through a discourse analysis approach.FindingsThree discourses of care and work were identified: a discourse on solidarity and care; a discourse on control and order; and a discou…
Temporality in cosmopolitan solidarity : Archival activism and participatory documentary film as mediated witnessing of suffering at Europe’s borders
2019
This article develops and extends the idea of cosmopolitan solidarity to temporality through a case study of archival activism and participatory film-making. It examines mediated witnessing within the Italian online audiovisual archive Archivio delle memorie migranti, which documents and archives the experiences of contemporary migrants in Italy. The moral basis of Archivio delle memorie migranti is cosmopolitan solidarity, which is usually understood as a practice that crosses spatial and communal boundaries. However, the ethics of solidarity also bridges past, present and future generations. Through the case of Archivio delle memorie migranti, this article demonstrates the significance o…
‘We hugged each other during the cold nights’: the role of affect in an anti-deportation protest network in Finland
2021
This article analyses the role of affect and emotions in Finland’s first large-scale anti-deportation protest, the 2017 Right to Live protest in Helsinki. Despite deportation protests having recently gained scholarly attention, their emotional dimensions have not been sufficiently studied, especially as concerns the emotions of protestors with vulnerable legal status. This article is based on in-depth interviews with key activists in the anti-deportation protest network in Finland, including asylum seekers, refugees and Finnish citizens. The article argues that in order for the protest of asylum seekers facing the threat of deportation to become public and visible, it was important that cit…
Nanotechnology for Cultural Heritage
2014
The conservation science is one of the most complex topics in the materials science as it requires interdisciplinary expertise ranging from the architecture, the technology of materials to the advanced analytical and physical chemistry. However, the recent development has shown that the complex tasks of the conservation of the cultural heritage can be solved very effectively using novel nanomaterials and nanotechnology methods.
Archaeometric analysis of Roman bronze coins from the Magna Mater temple using solid-state voltammetry and electrochemical impedance spectroscopy
2017
Voltammetry of microparticles (VMP) and electrochemical impedance spectroscopy (EIS) techniques, complemented by SEM-EDX and Raman spectroscopy, were applied to a set of 15 Roman bronze coins and one Tessera from the temple of Magna Mater (Rome, Italy). The archaeological site, dated back between the second half and the end of the 4th century A.D., presented a complicated stratigraphic context. Characteristic voltammetric patterns for cuprite and tenorite for sub-microsamples of the corrosion layers of the coins deposited onto graphite electrodes in contact with 0.10 M HClO4 aqueous solution yielded a grouping of the coins into three main groups. This grouping was confirmed and refined usin…
Grain-size-induced relaxor properties in nanocrystalline perovskite films
2004
Thin films of ${\mathrm{Pb}}_{0.76}{\mathrm{Ca}}_{0.24}{\mathrm{TiO}}_{3}$ (PTC), which is a classical ferroelectric as a bulk material and of the relaxor material $\mathrm{Pb}({\mathrm{Sc}}_{0.5}{\mathrm{Nb}}_{0.5}){\mathrm{O}}_{3}$, have been produced to find out whether nanocrystalline ferroelectric films show a grain-size-induced relaxor behavior. Amorphous films were deposited onto a $\mathrm{Ti}∕\mathrm{Pt}$ coated silicon (100) wafer by reactive $\text{rf}$ sputtering. Different grain sizes were prepared by a controlled annealing process and they were determined by profile analysis of x-ray diffraction spectra. Temperature dependent Raman spectroscopy was used to look for phase trans…
Case studies - Research and technological solutions to prevent sand production in the gas wells from the Getic Depression
2021
A frequent challenge encountered in the exploitation of mature gas fields located in the Getic Depression is sand production. Causes of sand production are mainly related to degree of rock consolidation, lithology, increasing water production and production rates. The effects of sand production are multiple such us low productivity of the gas wells, accumulation into the surface equipment, erosion of downhole and surface equipment, plugging the perforation zone and casing damage. The current paper will address the sand production- challenges and new perspectives in remedial work of wells which are producing from gas reservoirs located in Getic Depression. The article presents through some c…

Residual Stresses Induced by Cold Expansion of Adjacent and Cut-Out Holes
2012
Fatigue life of fastener holes can be enhanced via a cold-expansion process to introduce a compressive residual stress field around the hole edge and to reduce crack growth propagation. Considering that aerospace components contain multiple rows of holes, the present investigation focuses on the evaluation of the three-dimensional residual stress distribution in adjacent cold-expanded (CE) holes. The redistribution of residual stresses caused by a cut introduced between two adjacent holes was also investigated. Finite element (FE) analysis and experimental technique were used to assess the residual stress distribution in a 6082-T6 aluminum plate with two adjacent holes expanded sequentially…
