The present catalogue summarizes the information on species composition and distribution of ants in Bulgaria, known until 2010 from literature and museum collections. The authors have worked intensively on Bulgarian myrmecofauna for the last 10 years. The Bulgarian myrmecofauna currently comprises 163 species from 40 genera and 6 subfamilies. The species list accounts synonyms and the respective publications they were used in, as well as all known localities in Bulgaria. Known localities are grouped by geographical regions and maps with concrete localities or regions for each species are provided. The conservation status of threatened ant species is discussed. The catalogue of Bulgarian ants may be of interest to myrmecologists, ecologists, biogeographers, conservationists and any zoological library.
The increasing complexity of problems in semiconductor electronics and optoelectronics has exposed the insufficient potential of the technological doping processes currently used. One of the most promising techniques, which this book explores, is radiation doping: the intentional, directional modification of the properties of semiconductors under the action of various types of radiation. The authors consider the basic principles of proton interactions with single crystal semiconductors on the basis of both theory as well as practical results. All types of proton modifications of the materials known presently are analyzed in detail and exciting new fields of research in this direction are discussed.
