Opis:
Surfaces of amorphous ribbon Fe70V10 B20 were observed by means of the scanning tunneling microscope before and after the annealing in vacuum. The topographic images of the air-side surfaces after annealing are similar in the x-y plane and different in the z-direction. From the scanning tunnelling microscope images some information on the crystallization of amorphous ribbons can be deduced.

Opis:
In this paper we are concerned with the asymptotic behavior of random (unrestricted) infinite products of nonexpansive selfmappings of closed and convex subsets of a complete hyperbolic space. In contrast with our previous work in this direction, we no longer assume that these subsets are bounded. We first establish two theorems regarding the stability of the random weak ergodic property and then prove a related generic result. These results also extend our recent investigations regarding nonrandom infinite products.

Opis:
Golf to dyscyplina sportu, wymagająca od gracza bardzo dużej precyzji. Celem niniejszej pracy była analiza kinematyki kończyny górnej podczas swingu golfowego w warunkach rzeczywistych oraz z wykorzystaniem urządzenia Kinect. Pilotażowe badania doświadczalne przeprowadzono na jednej osobie, która wykonywała swing golfowy 10 razy w każdym etapie badań. Po przeprowadzeniu analizy kinematycznej zaobserwowano porównywalne wyniki dla obydwu etapów przeprowadzonych badań. Największą ruchomość podczas wykonywania swingu golfowego zaobserwowano w stawie łokciowym.
Golf is a sport discipline, which require of the player very high precision. The aim of this study was the kinematic analysis of the upper limb during golf swing using the Kinect device and in real conditions. Pilot experimental studies were carried out on the one person, who was obligated to perform swing golf 10 times in every stage of research. Kinematic analysis has shown that the results for both phases were comparable. The greatest mobility during golf swing was observed in the elbow’s joint.

Opis:
Based on new material from Germany and Spain, the echinoid “Lepidocentrus” ibericusfrom the Early Devonian (Emsian) of northern Spain is shown to be congeneric with Rhenechinusfrom the Hunsrück Slate of south−western Germany. New information on the lantern, pedicellariae and internal structure of the theca is provided, and confirms this genus as a member of the Echinocystitidae–Proterocidaridae clade and the most primitive of all Devonian echinoids. The two environmental settings in which Rhenechinus is found are very different: the Spanish specimens come from a relatively shallow−water bryozoan meadow setting while the German specimens are preserved in a deep−water setting. We deduce that the rare echinoid specimens from the Hunsrück Slate are all allochthonous, whereas the Spanish material is preserved in situ.

Opis:
Two marine invertebrate fossil assemblages from the Late Triassic Cassian Formation (Dolomites, northern Italy) were examined to assess their diversity and palaeoecology. Surface and bulk samples from the localities Misurina Landslide and Lago Antorno were taken and analysed separately. Both benthic assemblages are relatively similar in taxonomic composition. Gastropods form the most abundant and diverse group, followed by bivalves. Disarticulated echinoderm ossicles are also common in the bulk sample from Misurina Landslide, but they are rare at Lago Antorno. The Misurina Landslide outcrop has yielded two echinoderm Palaeozoic holdovers, the ophiocistioid Linguaserra triassica and plates of putative proterocidarids, supporting the earlier hypothesis that such basins acted as refugia. The gastropod species Coelostylina conica, Prostylifer paludinaris, and Ampezzopleura hybridopsis are characteristic elements of both assemblages. The gastropod Jurilda elongata, however, is the most abundant species at Misurina Landslide, whereas juveniles of the gastropod species Dentineritaria neritina dominate the assemblage from Lago Antorno. Newly described gastropod taxa are Angulatella bizzarinii Nützel and Hausmann gen. et sp. nov., Bandellina compacta Nützel and Hausmann sp. nov., and Ampezzogyra angulata Nützel and Hausmann sp. nov. Fifty-seven invertebrate species were found in the bulk sample from Misurina Landslide and 26 species were recovered from the bulk sample from Lago Antorno. However, sample size from Lago Antorno was much smaller than that from Misurina. Diversity indices (Shannon, Simpson, Berger-Parker) show similar moderate diversities in both assemblages. Rarefaction curves and rank-abundance distributions also point to very similar diversities and ecological structures of the fossil assemblages. Both assemblages are autochthonous or parautochthonous, stemming from basinal, soft-bottom habitats. Their taxonomic composition differs significantly from that of other faunas known from the Cassian Formation. The tropical marine Cassian palaeoecosystem was highly complex and its diversity is still far from being fully explored.

Opis:
Root distribution sampling techniques are often inaccurate, time consuming and costly. We present an inexpensive approach to soil profile-wall mapping using a desktop scanner that allowed us to spend reduced time in the field. The scanner was pressed onto the vertical surface of a 1 x 1 m soil pit and images of the roots were taken in situ. In a common garden planting of eleven, 30-year-old conifer and hardwood tree species in Poland, we compared root counts (number of roots cm–2) obtained by this method with independent measurements of root length density (RLD) obtained from soil cores. We found a positive correlation (Spearman rank correlation r=0.93; P<0.001) suggesting general agreement of the two approaches in ranking among the species. Soil coring as well as grid mapping with plastic overlays took a longer total time for quantifying root distribution than the scanning procedure. The desktop scanner approach we developed is an inexpensive, time efficient and accurate way of quantifying root distribution and abundance that allows a unique coupling of root data to soil properties.
