In certain heating processes simple ring inductors for induction heating, such as in soldering, are not always applicable, since the geometry of workpieces and/or the manufacturing conditions do not permit this. In these cases, certain types of split inductors or powerline inductors can help to extend the possibilities of application.

In a graph, a matching cut is an edge cut that is a matching. MATCHING CUT is the problem of deciding whether or not a given graph has a matching cut, which is known to be NP-complete even when restricted to bipartite graphs. It has been proved that MATCHING CUT is polynomially solvable for graphs of diameter two. In this paper, we show that, for any fixed integer d ≥ 4, MATCHING CUT is NP-complete in the class of graphs of diameter d. This almost resolves an open problem posed by Borowiecki and Jesse-Józefczyk in [Matching cutsets in graphs of diameter 2, Theoretical Computer Science 407 (2008) 574-582]. We then show that, for any fixed integer d ≥ 5, MATCHING CUT is NP-complete even when restricted to the class of bipartite graphs of diameter d. Complementing the hardness results, we show that MATCHING CUT is in polynomial-time solvable in the class of bipartite graphs of diameter at most three, and point out a new and simple polynomial-time algorithm solving MATCHING CUT in graphs of diameter 2. © Hoang-Oanh Le and Van Bang Le.

Anablepsoides lineasoppilatae, spec. nov. from south-eastern Peru (Departamento Puno and Madre de Dios) is here described. It is a member of the A. limoncochae group and differs from all the other species of this assemblage in its unique colour pattern. In A. lineasoppilatae, the red striped pattern on the flank reaches only to the posterior area of the pectoral fin (versus stripes reaching to the humeral region). Further it distinguished by a grey anal fin (versus yellow), by an inferior lip without any distinctive coloration (versus red inferior lip), by a dorsal fin with a low number of dots (versus transverse stripes on the middle of the dorsal fin) and by an absence of a dark margin on the dorsal fin (rather than a presence). © Senckenberg Gesellschaft für Naturforschung, 2013.

The invention relates to devices intended for treatment of materials in gas discharge plasma of low temperature, namely the induction plasma generator, placed inside the process volume (working chamber). The technical problem to be solved by the proposed invention is to increase the efficiency of the device; to improve the reliability of the device, increase purity of plasma environment and increase density of plasma generated; increase the life of device; reduce the level of noise; reduce the size of the device. Plasma generator as per first embodiment comprising a helical coil, placed inside a conducting screen, an inner surface of which is of a nearly cylindrical shape, moreover the space between the coil windings and between the coil and the screen is filled with dielectric, has a flat coil, the distance from plane of the coil to outer surface of dielectric is less than double thickness of the coil, and the distance from plane of the coil to the base of inner surface of the screen is greater than double distance from the plane of the coil to outer surface of dielectric. Plasma generator of the second embodiment has a flat coil, screen in the form of the ring which axis is perpendicular to the plane of the coil, the edge of the ring facing the volume, where it required to create plasma, is closed with dielectric. Plasma generator of the third embodiment has the screen electrically connected to one end of the coil, and the dielectric constant of the dielectric is in the range of 2.5 to 50. Proposed constructive design of generator provides higher plasma density and increased purity of plasma environment than in prior one, under the same conditions in the discharge chamber and at the same HF power supply. Proposed device has high efficiency, is reliable in operation, has a long life and small size.

Scientific journals were established in the Soviet occupied zone following WWII in order to distinguish themselves from the other occupying powers. Starting in 1949 a journal with the title “Psychiatry, Neurology and Medical Psychology” was founded as no publishing house existed in the field of psychiatry and neurology and it became necessary to establish a new journal that was competitive. The journal was primarily distributed in the German Democratic Republic (GDR) until 1990 but the interest internationally was very limited. State affairs had a great influence from the very beginning so that the political involvement was reflected in the selection of staff, such as the publishers and the head of the editorial department and by the close interconnection between the Society for Psychiatry and Neurology of the GDR and the editorship of the journal. The publishers who were primarily responsible and the authors were at the interface of politics and science. Nevertheless, in an international comparison many parallels can be found in the orientation with respect to the content. © 2014, Springer-Verlag Berlin Heidelberg.

Psychodynamic psychotherapy for people with psychoses and, in a narrower sense, for people diagnosed with schizophrenia has a long tradition. In the past 30 years, however, it has predominantly developed outside the institutions and their curricula. From the theoretical considerations of Mentzos, Lempa and Montag a new modified treatment technique arises that will be described in this article. It delineates a treatment manual in the form of a toolbox, which describes tools for each stage and each degree of severity of a psychotic illness. A prerequisite for a successful use of these specific psychotherapeutic tools, which are selected to match the ego stability of the person concerned, is a specific therapeutic attitude essential for this type of psychosis therapy. The toolbox thus makes it possible to initiate therapeutic processes in patients with acute as well as long-term psychotic illnesses of any degree of severity. © 2015, Springer-Verlag Berlin Heidelberg.

Sound insulation against traffic noise comprising low frequencies, which is noticed especially nearby routes with heavy traffic and nearby airports, is a challenging task especially in urban areas, where a good mixture of functions is wanted and a high demand on building Sites is given. Although some important studies emphasise Solutions on sound insulation of traffic noise from buildings, catalogues of building constructions and methods of implementation have yet to be developed. Knowledge gained by planning sustainable and energy efficient houses should get used and further developed for planning of sound insulation with external construction elements. Building constructions, which can preferably protect dwellings against traffic noise, are analysed. It is proposed to examine and catagorize facade- and roofconstruction elements in a new way, specially aiming at protection against maximum noise levels with low frequencies. To cope the challenges common efforts of involved building and acoustic experts - especially in renewing Standards as DIN 4109 - should get supported, in order to implement adequate sound insulation technology in constructing and rehabilitating buildings.

Berlin is already an exceptional city. That there arises an unprecedented commission such as a shared church among Christians, Jews and Muslims only reaffirms this condition. This project by Kuehn Malvezzi –still in the search of funding– represents a possibility so exceptional that is remarkable in itself, especially if its architecture seeks to reaffirm this condition of strangeness within the urban context. © 2016, Pontificia Universidad Catolica de Chile.

Within the last years considerable progress has been achieved in the noise policy for the railways. The EU has recently enforced revised sound emission limits for rail bound vehicles. The rail sector has developed an economic solution for the noise reducing retrofitting of the freight wagons, the so called LL brake shoes. In December 2012 Germany introduced a retrofitting programme for freight wagons consisting of state aid and noise differentiated track access charges. The railway noise "bonus" will no longer be applied by 2015 with a considerable improvement of the level of protection and the revised calculation scheme for the sound immissions, the Schall 03, has recently been enforced. Innovative solutions for noise reduction related to the infrastructure have been developed. These instruments and development have not yet contributed to a noticeable and accepted reduction of impairments. It is still uncertain whether and how fast these newly developed instruments and technical solutions will lead to real and considerable reductions of the noise impacts. The chosen strategies will be analyzed and evaluated, progress, risks and deficits will be outlined. Proposals will be made for a more effective design of the instruments.
