Biotopical distribution and seasonal activity of model species of the family Gnaphosidae (Araneae) in Zemen gorge (SW Bulgaria)

A faunistic study was carried out for three years in Zemen gorge (1984-1986). With the help of Barber-traps 675 gnaphosid spiders were caught in 4 localities, each with 2 habitats, meadow and forest. 23 species were found in total and their biotopical distribution was recorded. The investigated habitats are faunistically similar, mainly in qualitative respect. In addition data about the phenology of the most frequent species are presented. The males are most abundant in spring and summer and disappear in VIII, the females are most numerous after VII and can be found till the end of IX, whereas the juveniles can be found till the end of X. The species abundance reaches its peak in V-VI

A survey of spiders (Arachnida: Araneae) of Prince of Wales Island, Alaska : combining morphological and DNA barcode identification techniques

Surveys during the summer of 2004 and August 2009 on Prince of Wales Island, Alaska, USA resulted in collection of 1064 adult spiders representing 84 species. Barcoding of spiders collected in 2009 resulted in DNA barcode data for 212 specimens representing 63 species. DNA barcode data were then used to facilitate the identification of otherwise unidentifiable juvenile and female specimens as well as to investigate phylogenetically four lineages with large branch lengths between specimens. Using morphological and DNA barcode identifications provided a more complete list of identified specimens than was possible using morphological data alone

Sonata No.1 for Violin and Piano, Op. 80,by Sergei Prokofiev: A Guide to Interpretation

Sergei Prokofiev was an extremely prolific composer whose career brought him success throughout Europe and the U. S. as well as Russia and the Soviet Union. He wrote for nearly every genre, and his most popular works today include operas, ballets, symphonies, and concertos. As a pianist, most of the concertos and sonatas that Prokofiev wrote were for the piano. However, his contributions to the violin repertoire are significant. Prokofiev wrote two concertos and two sonatas for solo violin. Of these, Sonata No. 1 for Violin and Piano, Op. 80 is unique for many reasons. The piece took Prokofiev eight years to finish, an unusually long amount of time for a composer who normally wrote quickly. He began the piece in 1938, shortly after permanently returning to the Soviet Union. At this point, Prokofiev’s career and popularity seemed to be at its peak. By the time the piece was premiered in 1946, Prokofiev had been subject to Soviet censorship and travel restrictions. In addition, the overall tone of the sonata is significantly harsher and more melancholic than Prokofiev’s other works for violin. These characteristics give the sonata unparalleled potential for meaningful individual interpretations. It is the interpretation of this piece that is of primary focus in this instance. Several factors regarding the origins, context, and schools of interpretation are considered. These factors include details of Prokofiev’s biography leading up to Op. 80’s completion, a brief history of Op. 80’s composition and early reception, a formal analysis of the piece, a review of available recordings, interviews of professors at major conservatories in the U. S., and a comparison of available editions

Comparison of Industrial Dynamics of Food and Beverage Industry in Bulgaria, Romania and Greece

Industry dynamic is a key indicator for sustainable industry growth. It depends on variety of factors on international and regional level. One of the important driving forces on international level is seen in the face of economic and political alliances. Cultural and regional policies, and social behaviour are driving industry dynamics on a regional level though. Our hypothesis is that specific differences of industrial dynamics of the Balkan countries occurred based on economic and political alliances (EU membership; Euro zone, Black Sea Economic Cooperation). This hypothesis is verified with analysis of a traditional for the Balkans industrial sector like Food and Beverage. The paper aims to find out more evidence to verify a basic hypothesis. It includes a comparative analysis of some basic industrial dynamic’s indicators for the European Union (EU 16), Greece, Romania and Bulgaria. The analysed period is 2000-2010. The conclusions are concentrated mostly on Bulgaria.Food and Beverage Industry, Industrial dynamics, Industrial growth, Bulgaria, Greece, Romania, innovation practices in food and beverage, Agribusiness,

Hidden Quantum Critical Point in a Ferromagnetic Superconductor

We consider a coexistence phase of both Ferromagnetism and superconductivity and solve the self-consistent mean-field equations at zero temperature. The superconducting gap is shown to vanish at the Stoner point whereas the magnetization doesn't. This indicates that the para-Ferro quantum critical point becomes a hidden critical point. The effective mass in such a phase gets enhanced whereas the spin wave stiffness is reduced as compared to the pure FM phase. The spin wave stiffness remains finite even at the para-Ferro quantum critical point.Comment: 4 pages, Phys. Rev. B (Rapid) accepte
