Morphological ontogeny of Melanozetes azoricus with comments on Melanozetes (Acari: Oribatida: Ceratozetidae)

Abstract: In this study the morphological ontogeny of Melanozetes azoricus Weigmann, 1976 is described and illustrated for the first time and compared with that of other species of Melanozetes Hull, 1916. The juveniles of M. azoricus have a humeral organ and a humeral macrosclerite, with seta c1, that is typical of Melanozetes, and all juvenile stages and adult have broad leg femora, with large ventral carina, which often occur in Melanozetes. The juveniles of M. azoricus differ from those of other species by the shape of most gastronotal setae, whereas the adult differs mainly by the body size, shape of lamellar cusp, presence and shape of the translamella and shape of notogastral setae. The diagnosis of Melanozetes is unclear in literature, but we follow the setal diagnostic character of Melanozetes (14 pairs, including c2 and c3) that is supported by the size of humeral macrosclerite in the juveniles, with seta c1, and the length and location of solenidion ω2 on tarsus I of nymphs and adults; this solenidion is ...

Somatotype and body composition of volleyball players and untrained female students – reference group for comparison in sport

Abstract: Abstract There is substantial evidence that somatotype and success in sport and physical performance are positively related. Existing somatotype data on athletes are useful as guidelines for sport selection and choice of training appropriate to the enhancement of desired somatotype characteristics. Updated somatotype data from non-athlete reference groups complement comparative analysis applied in assessing the effects of the training process and selection. The aim of this study was to determine the somatotype of untrained girls studying at Warsaw University of Technology in 2011, in order to create a current reference group for comparison, and to investigate the difference in body build of female volleyball players compared with the non-athlete group. Twelve Second Division female volleyball players (age 21.6±1.5 years, body height 177.3±6.2 cm, body mass 71.0±6.5 kg, training experience 8.4±3.4 years) and 150 female untrained students of the University of Technology in Warsaw (age 20.0±6.4 years, body height 166.5±6.4 cm, body mass 59.7±8.4 kg) participated in a study carried out in 2011. Somatotype was determined using the Heath-Carter method. The volleyball players were a little older and were significantly taller and heavier than female students (p<0.05). Significant differences between the groups were found in breadth of the elbow, breadth of the wrist, biacromial diameter, arm circumference and crus circumference (p<0.05). The mean somatotype of the volleyball players was 4.5-3.4-2.8. (4.5±1.0-3.4±1.2-2.8±1.3), whilst that of the untrained students was 5.1-3.6-2.8. (5.1±1.4-3.6±1.1-2.8±1.3); the groups did not differ significantly in somatotype. The groups were significantly different in body composition (F [kg] and LBM [kg]), as estimated by BIA and anthropometric methods (p<0.05). No differences were observed between the groups in the skinfolds. Morphological characteristics of the female volleyball players depended on the competition level and performance. Somatic features of the bodies of the volleyball players were dominated by the height of the body and the associated magnitude of the constituent characteristics.

Scintillating Screens for Micro-Imaging Based on the Ce-Tb Doped LuAP Single Crystal Films

Abstract: Single Crystal Film (SCF) scintillators are key-components of today's high-resolution 2D X-ray detectors used at synchrotrons for applications such as X-ray Radiography, Computed Tomography (CT), laminography, full-field XANES, and topography. Due to its high density and effective atomic number, LuAlO3 (LuAP) perovskite has a great potential to replace or complement the currently used Eu-doped Gd3Ga5O12 (GGG:Eu) and Tb-doped Lu2SiO5 (LSO:Tb) SCFs. In this article we present the growth of LuAP single crystalline films on undoped YAlO3 (YAP) by the vertical dipping isothermal Liquid Phase Epitaxy (LPE) growth method. For the comparison of the light output of Ce and Tb doped LuAP SCF screens both cathodoluminescence (CL) and X-ray excited luminescence (RL) measurements were used. For investigations of Ce-Tb energy transfer in the afore mentioned oxide hosts, in addition to using traditional spectroscopic methods, we made time-resolved luminescent spectroscopy of Ce-Tb doped LuAP SCFs under excitation by pulsed synchrotron radiation at the Superlumi station (HASYLAB at DESY). Recently we have demonstrated the strong quenching influence of Pb2+ flux related impurity on the Ce3+ emission in the Ce-doped LuAP SCF screens. However our present investigation shows that Tb-doped LuAP SCFs are efficient X-ray scintillators, whose light output can be significantly increased by co-doping with Ce3+ ions. Namely, we demonstrate the efficient Ce→ Tb energy transfer in LuAP:Tb,Ce SCFs. Finally, as-grown LuAP:Tb and LuAP:Tb,Ce films were evaluated for high-resolution X-ray imaging using a spatial resolution target at the European Synchrotron Radiation Facility (ESRF), and displayed promising results.

Positions and intensities of hyperfine components of all rovibrational dipole lines in the HD molecule

Abstract: We report results of a theoretical analysis of hyperfine interactions in the HD molecule. We present the calculated coupling constants: spin-rotation, spin-spin and electric quadrupole coupling constants for all bound states of HD in its ground electronic 1Σ state. We provide a list of positions and intensities of 108 320 hyperfine components of 5 129 dipole transitions from the P and R branches. The positions and intensities of the hyperfine components are necessary for a proper interpretation of accurate measurements of rovibrational transition frequencies in HD which are used for tests of quantum electrodynamics of molecules and searches for new physics beyond the Standard Model.

Bees (Hymenoptera: Apiformes) in the Narew National Park

Abstract: In wetlands and adjacent habitats in the Narew National Park (northeastern Poland), 125 species of Apiformes were recorded. The bee diversity of the area was distinguished by very high contributions of Andrenidae (particularly of Andrena s. str.) and Apidae, but relatively low contributions of Megachilidae and Anthophoridae. Characteristic species include Bombus jonellus, while Andrena fulva has its easternmost locality there.
