AbstractEsophageal lung is a rare entity that results from embryological alterations during the formation of the ventral wall of the anterior intestine. The clinical manifestations of this pathology are vague, including respiratory or digestive symptoms, repetitive respiratory infections, dysphagia, or inability to swallow. The management is based on the exact anatomical and vascular abnormalities. We report the diagnostic and therapeutic approach in a preterm boy with esophageal lung. Also, we present a three-dimensional model for the classification of this pathology. In conclusion, the management relies on proper definition of the anatomy and the surgical strategy.

Universals Archive (Universal #1926) indicates a universal tendency for sound symbolism in reference to the expression of diminutives and augmentatives. The research ( Štekauer et al. 2009 ) carried out on European languages has not proved the tendency at all. Therefore, our research was extended to cover three language families – Indo-European, Niger-Congo and Austronesian. A three-step analysis examining different aspects of phonetic symbolism was carried out on a core vocabulary of 35 lexical items. A research sample was selected out of 60 languages. The evaluative markers were analyzed according to both phonetic classification of vowels and consonants and Ultan's and Niewenhuis' conclusions on the dominance of palatal and post-alveolar consonants in diminutive markers. Finally, the data obtained in our sample languages was evaluated by means of a three-dimensional model illustrating the place of articulation of the individual segments.

A model is suggested here which describes the theoretical relationships between different cognitive processes. It is hoped that this model will contribute towards a tightening of the scientific conceptual network, mainly on the “soft” side of cognitive processes theorization. Concepts which are hitherto loosely used will gain clearer, distinctive definition; this applies to concepts like imagery, imagination, fantasy, daydreaming, dreaming, divergent thinking, creativity, etc. In this same model the relationships between these concepts and concepts such as learning, problem solving, information processing, thinking, semantic organization, etc., as well as the relationships among the latter concepts to each other, will also become explicit.

The paper considers issues related to classifying techniques of educational activities. The lack of logically consistent overall classification of educational activities is emphasized. To develop such classification it is proposed to identify explicit and implicit attributes of the «technique» notion. One of the explicit attributes is a set of conditions necessary for the technique to be designed and implemented. Implicit attributes depend on psychological and pedagogical theories applied for technique designing in the course of pedagogical phenomena modeling. The author identifies three groups of explicit attributes, namely, educational goals; educational contents; contingent of learners. Possible variations of the said attributes are described. Also described are various taxonomies of goals, kinds of educational contents and types of learners by stage of education and intellectual development of learners. To facilitate classification of educational activities techniques the orthogonal three-dimensional model is constructed to serve as a morphological matrix, describing a set of technologies, necessary to implementing the State educational standards.

The term lepidic is used prominently in the recently published multidisciplinary classification of adenocarcinoma. The lack of use in common (nonmedical) English has led to some confusion over the proper definition of this term. This historical perspective traces the history of the term lepidic from its origins at McGill University in Montreal, Canada, through its uses in English pathologic descriptions, to its current state in pulmonary pathology.

Dilated cardiomyopathy (DCM) is a complex, etiologically heterogeneous myocardial disease, which is one of the main causes of heart failure and heart transplantation. In 2016, experts from the European working group proposed a new definition of cardiomyopathy, which includes intermediate variants with a change in phenotype in carriers of mutations from subclinical form to the full manifestations of the disease. The classification of DCM was supplemented with intermediate phenotypes with the inclusion of a hypokinetic form with reduced contractile function without ventricular dilatation and variants with predominant dilation or arrhythmogenicity. Pathological architectonics of DCM consists of many genetic determinants that interact with numerous environmental factors. Clinical manifestations depend not only on the malignancy and penetrance of the gene mutation, but also on a number of other causes — epigenomic factors, age, toxic effects, environmental aggressiveness, pregnancy, and the effects of other acquired diseases. The article summarizes the current epidemiological data and ideas about specific molecular changes with an unfavorable prognosis. For clarity, we present clinical observations of familial DCM with mutations in the RBM20 and LMNA genes.

The stress-strain state of thick-walled cylindrical perforated shell under internal pressure is consider. Defined the reduced stiffness of the shell by defining an equivalent thickness. A numerical calculation using solid (3D) and shell finite elements is done. Analyzed stress-straine state of circle perforating holes and the thickness of the wall. Compared the stress-straine state obtained on solid three-dimensional model with the results for a shell with equvivalent stiffness. Were given advice on the definition of strass-straine state by using the eqvivalent stiffness considering stress concentration.

The three-dimensional model rotor of vertical shaft impact crusher was established by using the three-dimensional software Solidworks and it was imported into the discrete element software EDEM for dynamic simulation. The force of the split cone, the motion trajectory and force of the particles were analyzed in rotor by using the post-processing function of EDEM. The results show that the split cone was mainly affected by the normal action of particles. According to the definition of impact wear, it was finally determined that the wear form of the split cone is impact wear.


The first part of this work described the analysis of the structure by trial and gave some account of the experimental measurements. It was shown that in contrast with planar aromatic structures like naphthalene and diphenyl, the dibenzyl molecule in the crystal extends in three dimensions. In the molecular model which gave the best explanation of the results the planes of the benzene rings were at right angles to the plane containing the zig-zag of the connecting CH 2 groups. On the basis of this approximation the experimentally determined structure factors for three zones of reflections have now been subjected to a double Fourier analysis, and the results, given below, lead to a more precise definition of the orientation and give a more direct approach to the details of the molecular structure and dimensions. In the final result the regular three-dimensional model is slightly modified, the planes of the benzene rings being apparently turned from 13° to 16° out of the symmetrical position.

There are currently no established therapies for post-traumatic headache (PTH). One key obstacle standing in the way of meeting this unmet need is the fundamental gap in our understanding of the clinical course and functional impact of PTH. In this presentation we examine the existing schema used to characterize the clinical characteristics of PTH, including the International Classification of Headache Disorders (ICHD), and find that they leave major unresolved questions about the diagnosis, classification, and measurement of the clinical impact of PTH. Specifically, current data suggest that the ICHD classification, which is based on the extent of brain injury and the duration of condition, have limited prognostic and treatment implications. There are several challenges to the classification of PTH, as the clinical manifestations of PTH do not map well to the primary headache disorders, and the definition of the continuous and chronic daily headache require further study. Importantly, the existing classification do not provide or imply specific outcome measures for PTH, again a fundamental roadblock to testing therapeutic hypotheses for PTH. We hypothesize that a symptom-based classification is needed to begin an examination of these unresolved questions, and to establish clinically relevant endpoints for research and clinical trials for effective therapies.

The lorry frame is the main carrying part of a lorry, composed of several components. These components are connected by joints into one structural unit and it forms the lorry chassis. The contribution of this article is focused on the strength analyses of a backbone frame, which is used on an off-road lorry chassis. Strength analyses are carried out utilising the finite element method. This article presents a created three-dimensional model of the frame and definition of boundary conditions (loads, the definition of degrees of freedom) needed for simulation computations. Results of the numerical calculations are the main parts of this article. Attention is mainly centred on the distribution of stresses of the frame under defined loads and its deformations.
