The authors analyze the theory used in many countries, containing two independent directions: 1) the theory of stability of rod systems, including flat frames; 2) the theory of calculation of structural elements from various materials.The main feature of these theories is the application of the principle of plastic fracture.The assumption about a p
Crustacean calcium bodies are epithelial sacs which contain a mineralized matrix.The objectives of this study were to describe the microscopic anatomy of calcium bodies in the terrestrial isopod Hyloniscus riparius and to establish whether they undergo molt-related structural changes.We performed 3D reconstruction of the calcium bodies from paraffi
Abstract Background Benthic ciliates and the environmental factors shaping their distribution are far from being completely understood.Likewise, deep-sea systems are amongst the least understood ecosystems on Earth.In this study, using high-throughput DNA sequencing, we investigated the diversity and community composition of benthic ciliates in dif
Traditionally, species of fish are identified based on morphological characteristics.Although these taxonomic descriptions are essential, there are cases where the morphological characters distinguishing these species show marginal differences.For instance, in the Poonch River in the Himalayas, there are 21 species, out of which some are morphologi
The author argues through an analysis of maritime practice, legal theory and statutory enactments that the pilot is not only an expert adviser but that he takes charge read more of and conducts a vessel.He distinguishes between conducting and commanding and points out that by recognizing that the pilot conducts a ship no charge in the nowadays wide
