ICT helps to overcome disabilities

As a result of technological progress ICT (Information and Communication Technologies) has created the so-called „digital divide“. Some people are unable to individually respond to this progress, but the proper use of ICT can help them overcome this handicap. One of the possibilities is to create accessible and usable applications depending on the character and level of disability. In accordance with the European CertiAgri project, e-learning tools are used for integrating people with disabilities into the horticultural area. The paper specifically describes examples of simple teaching aids from the practical „green care“ course, which focus on the skills of people with mental disabilities.ICT, mental disability, educational materials, CertiAgri, accessibility, usability., Teaching/Communication/Extension/Profession, GA, IN,

Molecules, morphometrics and new fossils provide an integrated view of the evolutionary history of Rhinopomatidae (Mammalia: Chiroptera)

<p>Abstract</p> <p>Background</p> <p>The Rhinopomatidae, traditionally considered to be one of the most ancient chiropteran clades, remains one of the least known groups of Rhinolophoidea. No relevant fossil record is available for this family. Whereas there have been extensive radiations in related families Rhinolophidae and Hipposideridae, there are only a few species in the Rhinopomatidae and their phylogenetic relationship and status are not fully understood.</p> <p>Results</p> <p>Here we present (a) a phylogenetic analysis based on a partial cytochrome <it>b </it>sequence, (b) new fossils from the Upper Miocene site Elaiochoria 2 (Chalkidiki, Greece), which represents the first appearance datum of the family based on the fossil record, and (c) discussion of the phylogeographic patterns in both molecular and morphological traits. We found deep divergences in the <it>Rhinopoma hardwickii </it>lineage, suggesting that the allopatric populations in (i) Iran and (ii) North Africa and the Middle East should have separate species status. The latter species (<it>R. cystops</it>) exhibits a shallow pattern of isolation by distance (separating the Middle East and the African populations) that contrasts with the pattern of geographic variation in the morphometrical traits. A deep genetic gap was also found in <it>Rhinopoma muscatellum </it>(Iran vs. Yemen). We found only minute genetic distance between <it>R. microphyllum </it>from the Levant and India, which fails to support the sub/species distinctness of the Indian form (<it>R. microphyllum kinneari</it>).</p> <p>Conclusion</p> <p>The mtDNA survey provided phylogenetic tree of the family Rhinopomatidae for the first time and revealed an unexpected diversification of the group both within <it>R. hardwickii </it>and <it>R. muscatellum </it>morphospecies. The paleobiogeographic scenario compiled in respect to molecular clock data suggests that the family originated in the region south of the Eocene Western Tethyan seaway or in India, and extended its range during the Early Miocene. The fossil record suggests a Miocene spread into the Mediterranean region, followed by a post-Miocene retreat. Morphological analysis compared with genetic data indicates considerable phenotypic plasticity in this group.</p

Clinical evaluation of ROM of shoulder joint in cadet and junior category players of so-called overhead sports

The title of the master thesis: Clinical evaluation of ROM of shoulder joint in cadet and junior category players of so-called overhead sports Abstract in English language: The goal of this thesis is to elucidate whether the "overhead" athletes like handballers and volleyballers suffer from extension changes and local hypermobility in their shoulder joints. These changes are going to be described by trigonometric measurements and hypermobility tests by Sachse. It is going to be determined which "overhead" athletes are affected the most. Their sex is going to be taken into consideration. The theoretical part of the thesis describes selected "overhead" sports and their strain on a human body from a kinesiologic point of view. Especially the impact of offensive blows in volleyball and throws in handball on shoulder joints are going to be examined. The thesis is going to examine a shoulder girdle from an anatomy, kinesiology, biomechanics, and physiology point of view. A chapter focused on hypermobility and it is classification is included too. 95 people without a prior injury of a shoulder joint in the age from 16 to 19 years old including 73 "overhead" athletes were tested. There were 30 men, 40 women, 34 handballers, and 39 volleyballers. In the control group, there were 22 people, of which 11 men and 11...Diplomová práce Název práce: Klinické zhodnocení stavu ramenního kloubu u hráčů kadetské a juniorské kategorie tzv. overhead sportů Vysoká škola: Univerzita Karlova, Fakulta tělesné výchovy a sportu, obor fyzioterapie Autor: Bc.

Optical properties of (GeSe2)100−x(Sb2Se3)x glasses in near- and middle-infrared spectral regions

International audienceChalcogenide glasses from Ge-Sb-Se ternary system with different antimony content were fabricated and basic physico-chemical properties (chemical composition, thermal characteristics, density) were evaluated considering the glassy network connectivity. Optical properties of the glasses were heavily studied employing transmission spectroscopy, prism coupling technique, and particularly spectroscopic ellipsometry covering broad spectral range (0.3-20 μm). Refractive indices data show very good agreement between ellipsometry and prism coupling techniques in near-infrared range. Moreover, the reliability of infrared spectroscopic ellipsometry was demonstrated for precise determination of refractive index of chalcogenide glasses in near- as well as middle-infrared spectral regions

Diagnostics of PV Modules Using Time Domain Reflectometry

In photovoltaic (PV) module diagnostics, themethods most frequently used are based on measuring DCcharacteristics (mainly I-V curves). In real installations, PVmodules are combined with inverters that operate on a highfrequency and are connected to a grid. With this in mind, itcan also be very useful to know certain AC parameters ofthe PV modules such as impedance. The method ofexamining the distribution of the impedance of the module(such as in the case of transmission lines) is called TimeDomain Reflectometry (TDR). By a specific distribution ofthe impedance, it is possible to find the location and todetermine the nature of a defect. Moreover, this method canalso be used to differentiate modules that have the samenameplate values

Remnants of an ancient deltaretrovirus in the genomes of horseshoe aats (Rhinolophidae)

Endogenous retrovirus (ERV) sequences provide a rich source of information about the long-term interactions between retroviruses and their hosts. However, most ERVs are derived from a subset of retrovirus groups, while ERVs derived from certain other groups remain extremely rare. In particular, only a single ERV sequence has been identified that shows evidence of being related to an ancient , despite the large number of vertebrate genome sequences now available. In this report, we identify a second example of an ERV sequence putatively derived from a past deltaretroviral infection, in the genomes of several species of horseshoe bats (Rhinolophidae). This sequence represents a fragment of viral genome derived from a single integration. The time of the integration was estimated to be 11-19 million years ago. This finding, together with the previously identified endogenous in long-fingered bats (Miniopteridae), suggest a close association of bats with ancient deltaretroviruses

Resurrection of an East African House Bat Species, Scotophilus altilis (Chiroptera: Vespertilionidae)

Several house bat specimens superficially resembling the white-bellied house bat Scotophilus leucogaster (Cretzschmar, 1830), were recently captured in southwestern Ethiopia and southern South Sudan. These S. cf. leucogaster differed from typical S. leucogaster by their slightly smaller size and ventral coloration, conforming instead with the original description of S. altilis Allen, 1914. Scotophilus altilis is an overlooked taxon known from the Blue Nile region in Sudan that is currently considered a junior synonym of S. leucogaster. Phylogenetic analysis of mitochondrial cytochrome b gene (cytb) sequences revealed S. cf. leucogaster as a sister clade to S. leucogaster with a genetic distance of ca. 10%. Comparative specimens of questionable S. nigritellus de Winton, 1899 from northwestern Ethiopia and a wing biopsy sample of another S. cf. leucogaster from western Kenya also fell within this clade. Sequence data from two nuclear markers (zfy and fgb7) corroborated the distinction of S. cf. leucogaster from S. leucogaster. Likewise, morphometric analysis of cranial data largely supported this distinction, as well as taxonomic affiliation with S. altilis based on comparison with the only available paratype specimen. The position of this paratype specimen within the new Scotophilus clade, inferred from analysis of a short fragment of cytb, confirmed its taxonomic identity. Based on the presented evidence, the overlooked East African taxon S. altilis should be resurrected as a full species within the genus Scotophilus

Raman spectroscopic detection of the T-HgII-T base pair and the ionic characteristics of mercury

Developing applications for metal-mediated base pairs (metallo-base-pair) has recently become a high-priority area in nucleic acid research, and physicochemical analyses are important for designing and fine-tuning molecular devices using metallo-base-pairs. In this study, we characterized the HgII-mediated T-T (T-HgII-T) base pair by Raman spectroscopy, which revealed the unique physical and chemical properties of HgII. A characteristic Raman marker band at 1586 cm−1 was observed and assigned to the C4=O4 stretching mode. We confirmed the assignment by the isotopic shift (18O-labeling at O4) and density functional theory (DFT) calculations. The unusually low wavenumber of the C4=O4 stretching suggested that the bond order of the C4=O4 bond reduced from its canonical value. This reduction of the bond order can be explained if the enolate-like structure (N3=C4-O4−) is involved as a resonance contributor in the thymine ring of the T-HgII-T pair. This resonance includes the N-HgII-bonded state (HgII-N3-C4=O4) and the N-HgII-dissociated state (HgII+ N3=C4-O4−), and the latter contributor reduced the bond order of N-HgII. Consequently, the HgII nucleus in the T-HgII-T pair exhibited a cationic character. Natural bond orbital (NBO) analysis supports the interpretations of the Raman experiments
