The rapid growth in use of mobile devices demands that libraries accommodate information presentation on smartphones and other small screens. Usability should be the focus for every stage of design, ideally following the conventions and best practices promulgated by the World Wide Web Consortium and codified by major manufacturers such as Apple, Android and Blackberry. A mobile device is not simply a reduced‐size desktop; its minimal real estate requires different design choices and compromises that affect reading, navigation and entering text. Testing and evaluating the mobile interface design and function require attention to the hardware, operating system and browser. Ideally testing should be performed on multiple hardware configurations and by a wide variety of users. Emulators, simulators and lab testing can be useful but should not replace usability evaluation by real people in real life situations.
The aim of the research was to develop a method for determining the species affinity of animal hair by determining its melting temperature. The research material was selected from hair samples of livestock and wild animals. We investigated 170 hairs of 16 animal species and humans. The hair melting point was determined by an automated system for melting temperature determination Opti Melt (MPA100). In the present study, we suggest that species affiliation can be effectively determined by examining physical properties of hair, in particular by determining its melting temperature. The hair melting temperatures for different animal species are in different ranges, but the initial melting points for hair of certain animal species are similar. For example, the initial melting point for cat, sheep, hare, rabbit, and rat hair ranged from 100 to 111 ° C, and the hair of the wolf, bear, and fox began to melt at 139.2 to 141.2 ° C. The results of this research make it possible to determine the species affinity of animals according to their hair melting temperature, which had not been done before. The proposed method yields rapid results and can be used as an auxiliary method in ambiguous cases in which data obtained by microscopic examination are insufficient. It will greatly facilitate the work of forensic specialists, enriching the arsenal of available methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
