Tsunami databases contain general information of historical tsunamis, which provides valuable and fundamental data to tsunami-related researches. Nevertheless, before adopting the information stored in various tsunami databases, users should be familiar with these databases’ individual features due to their inhomogeneity in data storage. To this end, a comprehensive review of the worldwide existing tsunami databases was conducted in this study. Two kinds of existing databases are recognized, i.e. the individual database and the organizational database. The individual tsunami databases are generally simple and descriptive with less information about tsunami and associated earthquake. Update of individual database is also out of date. Nevertheless, the organizational tsunami databases, with the retrieval function and timely update, are more sophisticated with significant research orientated information, upon which we can obtain the detailed characteristics of a specified tsunami event. In addition, a further comparison is made between two main organizational databases, i.e. the databases of NTL/WLD and NGDC/WDS. In which, the number of recorded tsunami wave heights per event and the number of definite tsunami events per decade both witness an apparent increase after 1900s, and the landslide-generated tsunamis are found to gradually increase after 1960s. The total tsunami events per decade fluctuate around one hundred since 1990s, whereas the definite tsunami events per decade experience a linear increase in this period. It turns out that though quite a part of the data in NTL/WLD is referred to NGDC/WDS, they do collect different tsunami events, and even for the same event, their recording datasets are still not consistent with each other. Figuring out the structural features of different databases and unveiling their connections and differences facilitate relevant research for disaster prevention and mitigation.

The article provides general information about the skin physiology of newborns and infants. Structural features of the skin and main adaptive shifts in newborns, are described. Тhe child has an increase in the skin barrier function of the skin, which prevents transepidermal water loss; active synthesis of natural moisturizing factor (NMF) components that control skin hydration; shift of pH to acidic environment; normalization of thermoregulatory functions; enhancement of the photoprotective function; immune restructuring for antimicrobial protection; formation of a normal microbiome. The article describes the consequences of improper skin care of a newborn, using the example of diaper dermatitis, irritant dermatitis, prickly heat and vesiculopustulosis. The importance of using specialized children's cosmetics in caring for an infant is assessed. The basic recommendations for the choice of these products are presented, where the main emphasis is on the choice of products consisting of natural ingredients. Giving preference to natural cosmetics, everyone should carefully study the composition of these products and trust the manufacturers who can guarantee safety of care products for the youngest children.

It is no secret that one of the features of today's global infomakon is manipulative information, which carries a large part of the General information complex that negatively affects public consciousness, the unity of the individual, society and the state. The main feature of modern journalism is that it completely rejects open propaganda and uses hidden methods of influencing the mind. Many news agencies have moved from direct ideological pressure on the recipient to theuse of hidden mechanisms of thought formation.

AbstractCurrent mainstream memory technologies are unlikely to completely fulfill the solid state data storage requirements that will be imposed beyond the 32 nm node of the International Technology Roadmap for Semiconductors. One potential replacement technology is resistance change memory based on solid electrolytes and a number of significant research and development efforts are already underway. The lowering of the resistance is attained by the reduction of ions in a relatively high resistivity electrolyte to form a conducting bridge between the electrodes. The resistance is returned to the high value via the application of a reverse bias that results in the breaking of the conducting pathway. Germanium chalcogenides and Ag-Ge-S ternaries in particular possess good thermal processing characteristics while maintaining the necessary high ion mobility for rapid switching. Thermally diffused copper in deposited SiO2 also is of interest, as thermal stability in excess of 600°C and commonly used constituents makes this material system compatible with the widest range of back-end-of-line processes. This paper details some of the developments in the understanding of the materials used in solid electrolyte resistance change devices and presents a short review of the electrical characteristics of devices based on Ag-Ge-S and Cu-Si-O electrolytes.

Purpose Two disastrous Tsunamis, one on the west coast of Sumatra Island, Indonesia, in 2004 and another in North East Japan in 2011, had seriously destroyed a large number of bridges. Thus, experimental tests in a wave flume and a fluid structure interaction (FSI) analysis were constructed to gain insight into tsunami bore force on coastal bridges. Design/methodology/approach Various wave heights and shallow water were used in the experiments and computational process. A 1:40 scaled concrete bridge model was placed in mild beach profile similar to a 24 × 1.5 × 2 m wave flume for the experimental investigation. An Arbitrary Lagrange Euler formulation for the propagation of tsunami solitary and bore waves by an FSI package of LS-DYNA on high-performance computing system was used to evaluate the experimental results. Findings The excellent agreement between experiments and computational simulation is shown in results. The results showed that the fully coupled FSI models could capture the tsunami wave force accurately for all ranges of wave heights and shallow depths. The effects of the overturning moment, horizontal, uplift and impact forces on a pier and deck of the bridge were evaluated in this research. Originality/value Photos and videos captured during the Indian Ocean tsunami in 2004 and the 2011 Japan tsunami showed solitary tsunami waves breaking offshore, along with an extremely turbulent tsunami-induced bore propagating toward shore with significantly higher velocity. Consequently, the outcomes of this current experimental and numerical study are highly relevant to the evaluation of tsunami bore forces on the coastal, over sea or river bridges. These experiments assessed tsunami wave forces on deck pier showing the complete response of the coastal bridge over water.

The article discusses the possibilities of computed tomography and magnetic resonance imaging when examining patients in an ENT clinic. The authors' materials cover complex observations of diseases of the nose and paranasal sinuses. The patients were operated on, which made it possible to compare the data of radiation studies with operational findings and cytological material. CT scan in coronal projection allows to clarify the diagnosis, determine the possible causes of recurrent sinusitis and identify the individual structural features of the nasal cavity and PNS that contribute to the development of intraoperative complications. When analyzing CT data, special attention should be paid to identifying and correctly interpreting the intranasal anatomy. It is necessary to indicate in detail the location of the cyst of the maxillary sinus, which allows the surgeon to correctly choose the optimal surgical access.

Secondary Bonding

The secondary bonding interactions that link the supramolecular structures assembled by 1,2,5-chalcogenadiazoles were analyzed through explicit orthogonalization of molecular orbitals (NBO), topological analysis of the electron density (AIM), and the electron localization function (ELF). The results of these analyses are consistent with a bonding description that attributes important covalent and electrostatic character to these interactions. Application of these analyses to the individual molecules highlighted the structural features from which each of those contributions originates, namely the polarity and modest strength of the E–N bond. Both of these effects increase along the series S, Se, Te. Perturbations to the heterocycle electronic structure that result in a weaker and more polar E–N bond cause an increase in the Lewis acidity at the chalcogen centre, which in turn leads to stronger secondary bonding interactions with Lewis bases. Additionally, the contribution of dispersion forces is not negligible and is most important in the case of sulfur.

Zebrafish Embryogenesis

Midkine is a heparin-binding di-domain growth factor, implicated in many biological processes as diverse as angiogenesis, neurogenesis and tumorigenesis. Elevated midkine levels reflect poor prognosis for many carcinomas, yet the molecular and cellular mechanisms orchestrating its activity remain unclear. At the present time, the individual structures of isolated half domains of human midkine are known and its functionally active C-terminal half domain remains a popular therapeutic target. In the present study, we determined the structure of full-length zebrafish midkine and show that it interacts with fondaparinux (a synthetic highly sulfated pentasaccharide) and natural heparin through a previously uncharacterized, but highly conserved, hinge region. Mutating six consecutive residues in the conserved hinge to glycine strongly abates heparin binding and midkine embryogenic activity. In contrast with previous in vitro studies, we found that the isolated C-terminal half domain is not active in vivo in embryos. Instead, we have demonstrated that the N-terminal half domain is needed to enhance heparin binding and mediate midkine embryogenic activity surprisingly in both heparin-dependent and -independent manners. Our findings provide new insights into the structural features of full-length midkine relevant for embryogenesis, and unravel additional therapeutic routes targeting the N-terminal half domain and conserved hinge.
