The aim of the present paper is to discuss metaphorical constructions, based on figurative uses of words, in informal Polish in the field of computers and the Internet. The study is based on the author’s own corpus, compiled on the basis of short informal texts (entries, posts) written on 32 selected Internet forums. Altogether, the corpus consists of 1,541,449 words. The paper, as the title suggests, focuses on one metaphorical formula, i.e. COMPUTERS ARE BUILDINGS. The metaphors which can be subsumed under this heading belong to the most frequent in the corpus (alongside a different type, i.e. COMPUTERS ARE HUMANS). They are discussed within the cognitive framework, as introduced by Lakoff and Johnson (1980). Some attention will also be devoted to the possible infl uence of English upon Polish metaphorical constructions used in the area of computers and the Internet.

Sensing technology has been developed for detection of gases in some environmental, industrial, medical, and scientific applications. The main tasks of these works is to enhance performance of gas sensors taking into account their different applicability and scenarios of operation. This paper presents the descriptions, comparison and recent progress in some existing gas sensing technologies. Detailed introduction to optical sensing methods is presented. In a general way, other kinds of various sensors, such as catalytic, thermal conductivity, electrochemical, semiconductor and surface acoustic wave ones, are also presented. Furthermore, this paper focuses on performance of the optical method in detecting biomarkers in the exhaled air. There are discussed some examination results of the constructed devices. The devices operated on the basis of enhanced cavity and wavelength modulation spectroscopies. The experimental data used for analyzing applicability of these different sensing technologies in medical screening. Several suggestions related to future development are also discussed.
