Tale(s) of a forest – re-creation of a primeval forest in three environmental narratives
2020
We analyze three environmentally conscious works that are concerned with the state of Finnish forests: the documentary film Metsän tarina/Tale of a Forest (2012), the book with the same name (2013) and the series of short documentaries Tarinoita metsästä/Tales from the Forest (2013). By combining methods from arts research and ecology, we ask how the narratives adapt material from nature photography. The film and book present mythic stories and old Finnish beliefs about forests. They also contain references to cultural memory. Additionally, the biodiversity on display reflects a conventional practice to exhibit large or charismatic species. However, the ecological message remains only impli…
Efficient photoinduced electron transfer in a porphyrin tripod-fullerene supramolecular complex via pi-pi interactions in nonpolar media.
2010
A novel porphyrin tripod (TPZn(3)) was synthesized via "click chemistry". Three porphyrin moieties of TPZn(3) are geometrically close and linked by a flexible linker. The electron-transfer oxidation of TPZn(3) results in intramolecular pi-dimer formation between porphyrin moieties as indicated by electrochemical, vis-NIR, and ESR measurements. The cyclic voltammogram of TPZn(3) exhibited stepwise one-electron oxidation processes of three porphyrin moieties in the range from 0.58 to 0.73 V (vs SCE in CH(2)Cl(2)). When TPZn(3) was oxidized by tris(2,2'-bipyridyl)-ruthenium(III) ([Ru(bpy)(3)](3+)), the oxidized species (TPZn(3))(n+) (0n/= 3) exhibited a charge resonance band in the NIR region …
The Prevalence of Visual Impairment in the Adult Population
2019
Background The distribution of visual impairment is an indicator of the health status of the population and for the frequency of diseases of the eye. Methods The Gutenberg Health Study (GHS) is a population-based cohort study in Germany concerning adults aged 35 to 74. 15 010 subjects from the Mainz-Bingen region underwent general medical and ophthalmological examination, with measurement of the distance-corrected visual acuity in each eye separately. As per the World Health Organization criteria, visual impairment was defined as an acuity below 0.3 in the better eye, and blindness as an acuity below 0.05. All patients who were found to be visually impaired or blind underwent further indivi…
The dialogue between east and west in the construction of gender photography as support of discourse and resistance
2018
En el marco de la globalización, en las nuevas narrativas de género se han producido cambios conceptuales con nuevos posicionamientos críticos y de resistencia. Mujeres creadoras de otras culturas, diferentes al mundo occidental, han trabajado para denunciar situaciones o poner en valor el empoderamiento de las mujeres como protagonistas de su destino. Y es en esta línea donde las mujeres artistas han aportado sus propuestas feministas y de resistencia. Los objetivos de este trabajo se centran en dos ejes conceptuales: a) analizar la situación de las mujeres en el contexto de los países islámicos y b), mostrar, a través del trabajo de fotógrafas procedentes de estos países, como se está con…

Forensic multidimesnional reconstruction as based on post-mortem image examination and spherical photography
2017
The aim of the paper is to present the methods of creating multi-dimensional reconstructions used in modern forensic medicine and state-of-the-art autopsy technique. Making use of the computer tomography technology and sophisticated software by the forensic pathologists allows a new standard of quality to be introduced into the forensic medical examination and hitherto unprecedented effects to be obtained. These developments significantly enhance the information available to the expert, particularly in case where an incident involved the use of firearms, the presence of foreign object in the body of the deceased, or advanced decay of the corps. Furthermore, the paper touches upon a subject …
Recuerdos figurados. "Fotos de familia" en Sicilia
2020
“Life is not what you have lived, but what you remember and how you remem- ber it to tell”. Taking cue from the words of Gabriel García Márquez, the essay analyzes a gallery of photographic images portraying “family photos”, made in Sicily between the end of the 19th century and the first decades of the 20th century, which are placed in an inter- mediate space between oral and written traditions becoming “biographical object”. The analysis of the photographic corpus searches for the connections between the different events that the image has gone through (production, transmission, fruition). It is in his “life story”, in his passage from one generation to the other, from one type of represe…
The Landscape as a Silent Witness of a Fragile Memory in Paweł Pawlikowski’s 2013 Film Ida
2022
This article focuses on Paweł Pawlikowski’s 2013 film Ida, analysing how the formal and aesthetic aspects question silent witnesses about the difficult past using pictures as a useful testifier. In the context of Poland’s national memory, its current political discourse and the Polish-Jewish relations during World War II, Ida offers a significant contribution. The process of scrutinising this difficult past becomes a journey, a troublesome event when a remembrance must be constructed and experienced. The film journey offers a possibility to get back to this period of time and encourages us to pose certain questions: how do sites of memory remain with us through cinematographic or photograph…
WhatsApp iconology: narratives on in-app photographic practices in (transnational) family communication
2023
Sharing photographs and photo-chatting are common practices in doing family at a distance. This study looks at the processes of the production and circulation of photographs within the family network, analysing participants’ narratives about their image-based communication in WhatsApp. The data was collected as an ethnographic enquiry into the digitally mediated (transnational) family communication of five Polish women and their children living in Finland. It consists of five auto-driven visual elicitation interviews with an interactive collage, three elicitation interviews, with the participant’s smartphone used for fast reference to their in-app chats, and one semi-structured interview. T…
Restoration and Enhancement of Historical Stereo Photos
2021
Restoration of digital visual media acquired from repositories of historical photographic and cinematographic material is of key importance for the preservation, study and transmission of the legacy of past cultures to the coming generations. In this paper, a fully automatic approach to the digital restoration of historical stereo photographs is proposed, referred to as Stacked Median Restoration plus (SMR+). The approach exploits the content redundancy in stereo pairs for detecting and fixing scratches, dust, dirt spots and many other defects in the original images, as well as improving contrast and illumination. This is done by estimating the optical flow between the images, and using it …
