Except for the individuals described here, the long and extremely fragile antenna 1, antenna 2 and pereopods 3 to 7 were broken off on all specimens of <i>T. namibiensis</i> sp. nov., or the specimens were significantly smaller. Male and female of <i>T. namibiensis</i> show no sexual dimorphism, besides the female may be expanded if oostegites are developed.</p> <p>The inner lobe of the left maxillula and the distal part of the merus of pereopod 2 were damaged during dissection. The cuticular wrinkles on the surface of pleopod 3 may be artefacts.</p>Published as part of <i>Brenke, Nils & Buschmann, Anika, 2009, Thylakogaster namibiensis sp. nov.

Data for the knowledge of the bag moth fauna of Hungary (Lepidoptera, Coleophoridae)
No full text<p>In parallel with the revision rearrangement of the Coleophoridae collection of the</p><p>Hungarian Natural History Museum (Budapest) in 2013–2014 (see Buschmann & Richter 2016)</p><p>the relevant part of my private collection was also arranged, based on the (Pastorális et al. 2012)</p><p>list of names then. Through the subsequent collections, I currently have 3097 specimens of 180</p><p>Coleophora species in my collection. In my publications, I present their data.

A fluorescent host-guest complex of cucurbituril in solution: a molecular Jack O'Lantern
No full textFluorescence enhancement of a probe molecule in solution by the container molecule cucurbituril (CB) is reported for the first time. The fluorescence of the probe 2-anilinonaphthalene-6-sulfonate (2,6-ANS) in aqueous Na2SO4 solution is found to increase by a maximum factor of 5.0 upon addition of cucurbituril. This fluorescence enhancement is the result of the formation of a host-guest inclusion complex, in which the guest 2,6-ANS is incorporated inside the cavity of the host, cucurbituril. Measurement of the enhancement as a function of cucurbituril concentration yielded a value of the equilibrium constant (K) of 52 +/- 10 M-1. It is proposed that the mode of inclusion involves the phenyl group of the 2,6-ANS, because of the relatively small size of the cucurbituril cavity. It is further proposed that the observed enhancement is a result of loss of rotational mobility of the phenyl ring relative to the naphthyl fluorophore of 2,6-ANS upon inclusion of the phenyl ring, Since the name cucurbituril is derived from the Latin word for "pumpkin," this fluorescent host-guest complex is referred to as a "molecular Jack O'Lantern," with the 2,6-ANS serving as the candle.PT: J; CR: BEHREND R, 1905, LIEBIGS ANN CHEM, V339, P1 BORTOLUS P, 1996, ADV PHOTOCHEMISTRY P, P1 BUSCHMANN HJ, 1992, J INCLUS PHENOM MOL, V14, P91 BUSCHMANN HJ, 1997, J INCLUS PHENOM MOL, V29, P167 BUSCHMANN HJ, 1998, THERMOCHIM ACTA, V317, P95 BUSCHMANN HJ, 1999, J PHOTOCH PHOTOBIO A, V121, P99 CINTAS P, 1994, J INCLUS PHENOM MOL, V17, P205 CRAM DJ, 1997, CONTAINER MOL THEIR DANTZ DA, 1998, SUPRAMOL CHEM, V9, P79 DELAPENA AM, 1993, J INCLUS PHENOM MOL, V15, P131 DIAMOND D, 1996, CHEM SOC REV, V25, P15 FREEMAN WA, 1981, J AM CHEM SOC, V103, P7367 HOFFMANN R, 1994, J CHEM SOC FARADAY T, V90, P1507 JEON YM, 1996, J AM CHEM SOC, V118, P9790 KOSOWER EM, 1975, J AM CHEM SOC, V97, P2167 KOSOWER EM, 1978, J AM CHEM SOC, V100, P4179 LI S, 1992, CHEM REV, V92, P1457 MOCK WL, 1983, J ORG CHEM, V48, P3618 MOCK WL, 1995, TOP CURR CHEM, V175, P1 MOCK WL, 1996, COMPREHENSIVE SUPRAM, V2, P477 WAGNER BD, 1998, J PHOTOCH PHOTOBIO A, V114, P151 WAGNER BD, 1999, J PHYS CHEM B, V103, P10114 WAGNER BD, 2000, J INCL PHENOM MACRO, V38, P467 WHANG DM, 1998, J AM CHEM SOC, V120, P4899; NR: 24; TC: 16; J9: CAN J CHEM; PG: 4; GA: 473RESource type: Electronic(1
Pilk Richard Viidalepa perekonnaloole
No full textRichard Viidalepp (Widebaum before Estonianising his name, and later Viidebaum; Jan. 23, 1904 - June 3, 1986), the famous Estonian folklorist, was born in the Jalapuu farm in the village of Nurmsi in Central Estonia. The same farm was the home of Urve Buschmann, the author of the article and R. Viidalepp's niece. On the basis of the 1722 list of inhabitants in the Särgavere estate and the registers of the Järva Peetri congregation, the documented genealogy of Viidalepp's family starts with Jüri Jalapuu and his wife Els (?1730-?1761). In more recent registers their son Jüri (?1771-1843) already appears under the name Widebaum. The family was a typical Estonian family, including farmers, handicraftsmen, inventive technicians, later also intellectuals and artists. Some emigrated (the Finnish and American branches of the Viidebaums) and some were deported to Siberia. The fate of family members and descriptions of family history are illustrated by Richard Viidalepp's letters and family photographs. The last Viidalepps born in the Jalapuu farm moved to Tallinn in 1950
Exceptional points in the thermoacoustic spectrum
No full textExceptional points are found in the spectrum of a prototypical thermoacoustic system as the parameters of the flame transfer function are varied. At these points, two eigenvalues and the associated eigenfunctions coalesce. The system's sensitivity to changes in the parameters becomes infinite. Two eigenvalue branches collide at the exceptional point as the interaction index is increased. One branch originates from a purely acoustic mode, whereas the other branch originates from an intrinsic thermoacoustic mode. The existence of exceptional points in thermoacoustic systems has implications for physical understanding, computing, modeling and control
