Udział Epifaniusza z Salaminy w walce z kultem obrazów

2017

Epifaniusz, biskup Salaminy na Cyprze w latach 376–403, należał do znaczących postaci w IV w. W działalności publicznej cechowała go radykalna postawa wobec prawd wiary, co bezpośrednio przekładało się na treść jego pism. Obok krytyki wszelkich przejawów heretyckiego myślenia zwalczał ponadto szerzący się wówczas kult obrazów. Taka opinia o nim stała się bardzo głośna dopiero w XX w., gdyż przed 100 laty, czyli w 1916 r., Karl Holl opublikował dosyć obszerne studium, w którym prezentuje tekst trzech utworów Epifaniusza potępiających oddawanie czci obrazom. Adresatami tych pism byli: biskup Jan Jerozolimski, cesarz Teodozjusz oraz członkowie jego wspólnoty kościelnej. Te trzy traktaty Epifan…

BIFOCAL PAIRS OF IMAGES FOR LOW-COST SURVEY IN CLOSE RANGE PHOTOGRAMMETRY

2019

Abstract. This paper present a method for close range photogrammetry based on an camera positioning scheme in which two cameras capture an equal portion of an object at the same scale, but have different focal lengths and camera-to-object distances. This scheme is alternative to the stereoscopic scheme and is associated with a system of equations which permits one to calculate first the relief displacement of points on a photograph and then their relief relative to a reference plane. The obtained relief and relief displacement values can be used to produce low-cost orthophotographs by using software for image processing, which doesn’t need to be dedicated, but has to provide measurement and…

Reconstruction of urban sites from photos

2019

Abstract. This paper reports the results of an experiment that aims at the virtual reconstruction of a urban site that has been partially reshaped during the 20th century; the reconstruction process is based on period photos. The chosen case study is the eldest harbour of Palermo, named ‘Cala’; the site was bombed during World War II and new buildings took the place of the ruined ones. Two period photos, taken from an aircraft, document the buildings that were destroyed by bombs. The 3D restitution process used the ‘inverse’ projection from period photos (2D) to the virtual space (3D) ; the first step was therefore addressed to the calculation of the inner parameters (focal length, principa…

EXPERIMENTAL INVESTIGATION OF DILUTE SOLID-LIQUID SUSPENSION IN AN UNBAFFLED STIRRED VESSELS BY A NOVEL PULSED LASER BASED IMAGE ANALYSIS TECHNIQUE

2009

The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-intrusive technique for measuring particle concentration fields in solid-liquid systems is employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images. Experimental data are here obtained for the case of an unbaffled stirred tank. Stable tor…

Potential of thermal images and simulation models to assess water and salt stress: Application to potato crop in central Tunisia

2017

The growing water scarcity is a real concern in Mediterranean countries characterized by semi-arid or arid climate such as Tunisia, where it is crucial to improve water use efficiency without affecting agricultural productivity. The importance of identifying methods and technologies to optimize water use in agriculture has been recognized worldwide, in response to the limited water availability. Objective of the paper was to verify the potential of the combined use of infrared thermography and simulation models to assess the effects of water and salt stress on potato crop parameters and crop yield, under the environmental conditions of central Tunisia. The database collected with field expe…

Le infinite vite delle fotografie: l’ecologia delle immagini di Joachim Schmid

2015

The turn from analogue to digital photography requires rethinking the heuristic potential of this medium: in the last century, it was produced countless photos and we lost the sense of them. What should we do with all these pictures? Joachim Schimd reflects on the abundance and proliferation of images and he works to give them a future in the age when digital technology changes our sense of what it means to take a picture. So we need an ecology of images which consists in the re-use of all the existing photos by an aesthetics of remix able to reorganize the sense of the images.

Das Körpererleben gynäkologischer Patientinnen vor und nach radikaler Chirurgie

2001

After radical gynecologic surgery women are faced with therapy-induced changes of their body. Since 1995, the body images of women who undergo pelvic exenteration, Wertheim-Meigs-operation or hysterectomy are assessed preoperatively and four and twelve months postoperatively. The aim of this multidimensional prospective study is to get basic information for effective counselling and support. One year after hysterectomy women state to have a normal body image. Cancer patients feel less attractive, less self-confident and more discontented in sexuality depending on therapy-induced changes of their bodies. These women could profit from problem-related preoperative counselling. Postoperative co…

Oropharyngeal Hairy Polyp: A Case of Respiratory Failure in a Newborn

2020

Hairy polyps, also known as dermoid polyps (DPs), are rare benign cystic lesions of bigerminal origin that may occur in several head and neck regions, including the oropharynx. Despite their benign histopathological nature, DPs may be life threatening, due to their upper airway location, and DPs represent one of the most unusual causes of respiratory distress during the neonatal period. In this paper, we describe a case of respiratory failure in a newborn with an oropharyngeal mass that was accidentally found during difficult intubation. Magnetic resonance imaging (MRI) detected a well-defined soft tissue pedunculated mass, arising from the left oropharynx wall, consistent with an oropharyn…

Focal liver lesions hyperintense on T1-weighted magnetic resonance images.

2009

This article reviews focal liver lesions hyperintense on T1-weighted magnetic resonance (MR) images and describes the underlying etiologies associated with their T1 signal intensity. Although focal liver lesions are commonly detected because of their iso- or hypointensity on T1-weighted images, lesions (benign or malignant) may present with T1 hyperintensity when they contain T1 shortening elements--such as fat, hemorrhage, copper, melanin, and highly concentrated proteins. Our discussion includes the description of state-of-the-art T1-weighted MR sequences and the imaging features of lesions on pre- and postcontrast MR images that are characteristic for lesion composition and useful for ma…
