In illuminance meter verification system, there are many factors that affect verification accuracy. If we can reduce or avoid these factors, the verification system will improve verification accuracy to meet research needs and customer requirements. This paper analyzes the factors in detail during the testing process, such as positioning accuracy and voltage fluctuation. It will help to provide theoretical basis for the future system improvements.

The aim of the article is to recall the fi steps of comprehension by the scientific community of possibilities of a newly born means of the reality reflection. The means was initially oriented for obtaining reliable information and supposing a delayed reaction of the spectator in the process of communication. Recollection and understanding become more important under the distance education condition. Pre-revolutionary Russia lived anticipating changes, and the filmmaking was considered by the society as one of those progressive phenomena evidencing the coming of a new age. The scientists’ activity during the development of scientific fi in pre-revolutionary Russia was long hushed up and wasn’t considered as forming a basis for the future system of educational audio-visual communication. In this process there participated striking, creative personalities, mostly belonged to the community of Imperial Moscow University, which activity was during the age of changes. The significant contribution of pleiad of eminent scientists’ activity to the new direction formation was a reason to unify in one paper both their whole professional life data and information about their time-limited period of scientific fi In the future a more profound study of their achievements are considered to be promising. In the introduction the anterior period of the Russian fi appearance, where the scientific and education community of Russia was exploring the possibilities of a new means of information transfer for education purposes, is considered. Two main units are dedicated to the role of scientists in the development of scientific filmmaking for research and popularization of biomedical and physical problems.

<p>Weeding is the removal and disposal of materials from a library’s collection that meet criteria set out in the collection development policy. Weeding the print collection of an academic library should be viewed as a means of continuously improving the quality of the collection, reflecting changes in the university’s academic curriculum and meeting patrons’ research needs (Dubicki, 2008). Weeding is often neglected however because of time constraints, a desire to maintain the size of a collection, and the belief that a book may be needed some time in the future ...</p>
