This paper presents a study of the possibilities of evaluating thermal parameters of single and multilayer structures using dynamic thermography. It also discusses potential uses of lock-in thermography. It presents a simulation of a periodic excitation of a multilayer composite material. In practice, the described methods can be employed in various(More)
Psoriasis vulgaris is a chronic inflammatory skin disease with a strong genetic component, characterized by hyperkeratosis, dermal inflammatory infiltrate and increased angiogenesis. The aim of the present study was to employ thermography in evaluation of psoriatic lesions localized in different parts of the body. A series of in-patients with stable plaque(More)
Psoriasis vulgaris affects about 2% of the human population all over the world. The aim of this study was to evaluate usefulness of thermography in estimation of psoriatic lesion activity. A series of patients with plaque type psoriasis vulgaris were included. ThermaCam INFRAMETRICS 290E thermocamera with temperature resolution of 0.1 degrees C was(More)
PURPOSE To measure the temperature parameters on the corneal surface during the delivery of standardized ultrasound energy assisted with ophthalmic viscosurgical devices (OVDs) or different temperatures of irrigating solutions in an experimental animal model. SETTING Department of Ophthalmology and Visual Rehabilitation, Medical University of Lodz, and(More)
Work in difficult conditions resulting from limited visibility in conjunction with restricted movement and complexity of performed operations involves high risk. The hazard can be reduced significantly through rapid provision of information on the risks people are exposed to under certain working conditions. Their reactions - classified as improper - result(More)
Some amounts of ultraviolet radiation are beneficial for humans but excessive exposure can cause many negative health effects to the skin and eyes and also can affect the immune system. Exposed area of skin should be covered by working clothes with low UVR transmission. It concerns both exposure to natural UV or prolonged exposure to artificial UV. This(More)
With the help of the research results presented here and on the basis of a graphic analysis we aim to prove the existence of a relationship between the difference in prismatic refractive power and the thickness, curvature radius, and type of material used for panoramic oculars in protective spectacles, goggles, and face shields. The difference in the(More)
This article presents a comparison of the test results of selected mechanical parameters (hardness, Young's modulus, critical force for delamination) for protective filters intended for eye protection against harmful infrared radiation. Filters with reflective metallic films were studied, as well as interference filters developed at the Central Institute(More)
PURPOSE To quantify the maximal level of temperature and the time the maximal temperature is achieved and correlate the temperature parameters to the mean rate of endothelial cell loss after standardized ultrasound delivery assisted with four viscoelastic substances or different temperature of balanced salt solution (BSS). METHODS Thirty rabbits (60 eyes)(More)
