The subtropical low-boreal chiton Lepidochitona cinerea (L., 1767) was found in intertidal pools on Tromso Island in northern Norway. Although remote from the main part of the species' distribution range, the population appears to be safe, with a regular annual recruitment. It is thought that L. cinerea invaded northern Norwegian waters during a period of warming, either 5 to 6 millennia or possibly just one millennium ago. Subsequent cooling destroyed the constant cinerea that remained in the intertidal pools could persist due to the species tolerance for severe winter temperatures, as well as the considerable warming of water in the pools during the prolonged boreal Tonicella rubra (L., 1767), as well as the boreal-arctic T. marmorea (Fabricius, 1780) and Stenosemus albus (L., 1767), were found in the same intertidal pools, possibly having arrived there as a result of storms. 11 pp., 5 figs, gr. 8. …

The deep-sea Ferreiraella gen. n. (the type species F. caribbensis sp. n.) comprises 6 species: F. scrippsiana, F. bartletti, F. takii, F. soyomaruae and F. plana which were earlier referred to the genus Lepidopleurus. Despite the discontinuous range (F. caribbensis and F. bartletti occur in the Atlantic Ocean and the Caribbean Sea, F. scrippsiana inhabits the Pacific Ocean southwest of California and F. plana, F. takii and F. soyomaruae are common off Japan, Vietnam and Indonesia) the species of the genus can be regarded as a morphologically and ecologically integrated group. All the species are deep-sea, stenothermic and stenohaline. They inhabit depths from 700 to 6,780 m on wooden substrates. 11 pp., 4 figs, gr. 8.…

Mohnia kurilana Dall, 1913 was described more than 100 years ago from deep waters off the Kuril Islands and remains exceedingly rare in museum collections. Originally placed in the carnivorous neogastropod family Buccinidae, fragmentary soft parts from the type lot and from several specimens belonging to allied species collected in the Aleutian Islands in the 1990s have allowed anatomical investigations for the first time. These have revealed the presence of a paucispiral operculum with an eccentric nucleus, foot with a deep propodial pedal gland and metapodial pedal gland, taenioglossate radula, short acrembolic proboscis, well-developed mid-esophageal gland, glandular prostate, and the absence of a penis; the nervous system is epiathroid with a long supra-esophageal connective and numerous statoconia in the statocysts. Analysis of the gut contents revealed abundant halichondriid sponge spicules. This evidence indicates a placement in the Triphoroidea, a diverse superfamily of specialized spongivores. Mohnia kurilana is transferred to the Newtoniellidae and placed in the new genus Pseudomohnia gen. nov. Pseudomohnia rogerclarki sp. nov. is established for a new species from the Aleutian Islands characterized by its narrowly turreted shell and distinctive multicuspid rachidian. A lectotype is designated for Mohnia kurilana. New taxa: Pseudomohnia n. gen., Pseudomohnia rogerclarki n. sp. 19 pp., 7 figs, gr. 8 [16.5 x 23.7 cm].…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The focus of electromagnetic theory is initial boundary value and boundary value problems for the Maxwell equations. Those are the initial models, from which, by applying mathematical methods, we should extract physical results. The modern computer-aided research process can be divided into several stages: qualitative mathematical analysis of the initial problem, the development of algorithms and implementation of the problem in software, problem-oriented computational - periments, and physical interpretation of the results. The success of the study depends in many aspects on whether suf ciently high standards of investigation can be maintained at all these stages and whether there is an 'intellectual core' in these investigations that enables us to gain new scienti c knowledge [1]. As an exampleofasuccessfulimplementationofsuchanapproachthathassettledalo- standing con ict between theory and experiment, we can cite the development of thetheoryofresonantwavescatteringinthefrequencydomain. Theseresultshave been reported (see [2-16] and the bibliographies contained in those references), andtheyhaveservedasabasisforthedevelopmentofanumberofessentiallynew functional units and devices in millimeter and submillimeter radio engineering, vacuum electronics, and solid-state electronics, optics, and spectroscopy. The modern theory of transient electromagnetic elds is still lacking achie- ments that may be compared with those existing in the frequency domain, neither by the profoundness of the study, nor by the intensity of the study of electrom- netic phenomena and, as a result, by their applications. However, the process of accumulation of potentialities for a breakthrough is a process still going on.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The problem of determining the location of an object, which is usually called ranging, attracts at present much attention in many different areas of applications, among them in ecological and safety devices. Electromagnetic waves along with sound waves are widely used for this purpose. Familiar examples of ranging systems are radar, sonar, GPS positioning, speed meters, etc. Most are echo-type of devices, generating a wave and interpreting its echo from the object of interest. GPS is a cooperative system, in which the receiver observes timing signals from sources at known locations, and locates itself in reference to them. Passive ranging makes use of waves generated by the object to be located that are picked up by an observer. As indicated, there are three kinds of ranging systems, successively described as echo, cooperative and passive systems. Echo ranging is by far the most common method in practice. The observer at a certain point emits a wave of some physical nature at a certain time. When the outgoing wave front strikes the object, a scattered wave front is launched, which is detected at the observer point a certain time interval later. …

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book gives guidance to solve problems in electromagnetics, providing both examples of solving serious research problems as well as the original results to encourage further investigations. The book contains seven chapters on various aspects of resonant wave scattering, eachsolving one original problem.All of them are unified by the authors' desire to show advantages of rigorous approaches at all stages, from the formulation of a problem and the selection of a method to the interpretation of results. The book reveals a range of problems associated with wave propagation and scattering in natural and artificial environments or with the design of antennas elements. The authors invoke both theoretical (analytical and numerical) and experimental techniques for handling the problems. Attention is given to mathematical simulations, computational efficiency, and physical interpretation of the experimental results. The book is written for students, graduate students and young researchers.…
