Abstract:

In early twentieth-century France, syphilis and its controversial status as a hereditary disease reigned as a chief concern for physicians and public health officials. As syphilis primarily presented visually on the surface of the skin, its study fell within the realms of both dermatologists and venereologists, who relied heavily on visual evidence in their detection, diagnosis, and treatment of the disease. Thus, in educational textbooks, atlases, and medical models, accurately reproducing the visible signposts of syphilis – the colour, texture, and patterns of primary chancres or secondary r

Abstract:

This article sets out to challenge the idea of photography as a medium that deals purely in the visible. Taking the example of the mid-twentieth-century British photography industry, this article considers photographic sensitivity as part of a sensory economy in which human, technological and environmental sensing are mutually entangled. I emphasise these interlinked sensing systems, and what I see as the “passive agency” of photographic materials, showing how photographic emulsions are capable of registering much more than visible light or even radiation.

By the early years of the twentieth century, astronomers regarded photography as one of the most valuable tools at their disposal, a technique which not only provided an accurate and reliable representation of astronomical phenomena, but also radically changed the role of the astronomical observer.

Although much of the previous work on mobile photography has focused on its role for visual communication in networked visuality (Van House et all. 2005; van Dijck 2007, 2013, etc.), the substantial proportion of mobile digital photography remains unshared. Visuality may not be a core practice to frame such photos practiced within wider practical contexts such as inscribing, personal archiving, carrying-with, and even being forgotten.

Abstract:

Solar cells using dyes as sensitizers continue to expand. The synthetic dye used as a sensitizing material for solar cells has high production costs, difficult to find, and can cause environmental pollution. Photosynthetic pigments as sensitizers are considered to be the solution to this matter. In this research, we investigated the effect of photosynthetic pigments from the Navicula sp. TAD as a dye-sensitized material on the efficiency of Dye-Sensitized Solar Cell. To obtain high biomass, the Navicula sp. TAD was cultivated in a modified medium.

Abstract:

After being weaned, the Wistar rats (12) were fed on a sucrose diet for five weeks to induce dental caries. Tetracycline was injected intraperitoneally into 7 of them to label the mineralizing dentin front. Five rats without tetracycline injection were used to verify spontaneous fluorescence. The evidently carious area under one prominent fissure from each mandibular molar hemisected sagittally in the midline was photographed under ultraviolet light so that autofluorescence would be revealed. The jaws were then stained with Schiff's reagent and photographed under normal light and again under u

Abstract:

The technical textiles are very sensitive materials. To measure the elongation of such a material needs special care. A photographic procedure has been investigated to measure the plain elongation of textile specimens. It is especially suitable for long-term measuring programs. Some experimental results measured by the described method are published.

Abstract:

Background Sore throat is a common problem and a common reason for the overuse of antibiotics. A web-based tool that helps people assess their sore throat, through the use of clinical prediction rules, taking throat swabs or saliva samples, and taking throat photographs, has the potential to improve self-management and help identify those who are the most and least likely to benefit from antibiotics. Objective We aimed to develop a web-based tool to help patients and parents or carers self-assess sore throat symptoms and take throat photographs, swabs, and saliva samples for diagnostic testing

Technology is gaining ground in the field of dermatology. Technological advances, mainly provided by mobile phones, offer almost limitless opportunities for medical applications. Mobile devices make it extremely easy to import and transmit information (e.g. photographs, patient data) for further analysis. However, it is important to note that the handling of health-related information, which is sensitive data, requires particular care - which in many cases is not given due attention. New mobile phone applications are appearing almost daily that can benefit both lay people and doctors in diagno

As we know, the first report on photographic plate hydrogen hypersensitisation (hypering) is dated 1871 (U.S. Patent No. 113327, April 4 1871, see Janusonis et al. 1978). A new interest in the topic appeared in the 1930s, after the work of Robert Kozlowsky at Agfa Wolfen. Kozlowsky was the inventor of gold sensitization. In the 1950s in Russia the action of hydrogen on thick nuclear emulsions was also studied (Tschernyavsky et al. 1962). Strong fogging, especially at increased temperatures, was observed.

Abstract:

ArgumentThis article explores the entangled histories of three imaging techniques in early nineteenth-century British physical science, techniques in which a dynamic event (such as a sound vibration or an electric spark) was made to leave behind a fixed trace on a sensitive surface. Three categories of “sensitive surface” are examined in turn: first, a metal plate covered in fine dust; second, the retina of the human eye; and finally, a surface covered with a light-sensitive chemical emulsion (a photographic plate).

Abstract:

Photographs of turfgrass canopies were taken throughout Spring, Summer, and Fall 1997 at a height of 1.3 m using a 28-mm lens and film sensitive to either visible or infrared light. The species evaluated were warm-season Bermudagrass, buffalograss, zoysiagrass, and cool-season tall fescue. Color spectra of digitized photographs were obtained by first separating the hue, saturation, and intensity components of the color photo into separate 8-bit (256 gray levels) files. Calculations were then made on the basis of those color components. The infrared photos were scanned as 8-bit files without co

Abstract:

We present a new technique in double star photography leading to high accuracy measurements in amateur-size instruments. The trailing method has been improved by the use of a chopper that cuts the trail into a number of segments. The chopper period is accurately known, so it is the length of each segment on the plate. In this way the scale factor is measured in each exposure. Fine-grain films, such as hyper-sensitized Kodak 2415, are used and all measurements are performed at the microscope. The same technique may also be applied to CCD cameras. A statistical analysis of errors shows that Δθ ≤

Characteristics of electron microscope film emulsions, such as the speed, the modulation transfer function, and the exposure dependence of the noise power spectrum, have been studied for electron energies (80-100keV) used in conventional transmission microscopy. However, limited information is available for electron energies in the intermediate to high voltage range, 300-1000keV. Furthermore, emulsion characteristics, such as optical density versus exposure, for new or improved emulsions are usually only quoted by film manufacturers for 80keV electrons.

Abstract:

The modern photographic emulsion is an extremely sensitive detector of light quanta. In fact, high speed black-and-white film (which consists mainly of microcrystalline grains of AgBr or AgBrI suspended in gelatin on an inert base) ranks with the photomultiplier tube as capable of detecting a very few individual light quanta. Exposure times can vary from minute fractions of a second to hours. Unlike the multiplier tube, the photographic emulsion also responds well to relatively high light flux, that is, film can have wide exposure latitude. In many respects such as sensitivity, latitude, resol
