Multielement study in the drainage sediments of a part of Lesser Himalaya, central Nepal
Authors: Jnawali B. M 
Published: April 2021

Distribution of different elements from 183 regional stream sediment samples representing 600 Km2 of Chitwan-Dhading Districts (Toposheet 72A/14) has been described. The study of inter-element relationships demonstrated positive correlation among Cu, Pb & Zn. Arsenic Sb & Bi correlations are found to be positive except that Bi & Sb exhibit antipathetic relation, the former showing affinity towards granite in contrast to the latter, which was virtually absent in anomalous amount over granites. A close association of As with Cu, Pb & Zn anomalies suggest that As could be used as a pathfinder for basemetal mineralization.
Regression analysis was used to study the effect of secondary hydroxides of Fe, Mn & Ni on Cu & Zn dispersion, and that of K on Sn & Pb dispersion. The only significant variance explained was Fe on regression of Cu, which was attributed to primary coherence of Cu with Fe probably in chalcopyrite or mafic minerals. The geochemical associations found in stream sediments reflect primary environment and secondary processes in surficial condition modify these very little.

Authors: Marharyta Yu. Sliepchenko  
Published: April 2021

To achieve the aim there has been examined 104 children aged 1–3 years with moderate and severe forms of intestinal infection of rotavirus etiology, for which they received appropriate treatment in Kharkiv Regional Children's Infectious Diseases Clinical Hospital. Patients were divided into 2 groups: 1 group — 33 children with no concomitant herpesvirus, and 2 groups — 71 patients with rotavirus gastroenteritis and latent herpesvirus infection, caused by cytomegalovirus, Epstein-Barr virus or human herpes virus 6. Children in examined groups were comparable by gender, age, severity of main disease and other parameters.Prognosis of latent herpesvirus infection was made by means of multiple binomial regression. Independent predictors of concomitant herpesvirus infection included maximal daily number of vomiting, maximal increase of body temperature, time of onset of catarrhal symptoms since beginning of disease, level of ketone bodies in urine, amount of leukocytes, rod-shaped neutrophils and eosinophils in common blood count during acute phase of disease. As a reference group, we used respective clinical and paraclinical indices of patients with rotavirus infection only. Accuracy of model is 81.73 %.
Anesthésie locale sur patient éveillé et sans usage du garrot dans les fractures bimalléolaires
Authors: Rafiqi K. , Nkaoui M. , Benlenda O. 
Published: April 2021

Les fractures de la cheville font partie des fractures les plus fréquentes chez l’adulte. Les fractures bimalléolaires sont généralement opérées sous anesthésie générale, rachianesthésie ou bloc tronculaire. La technique WALANT (Wide Awake Local Anesthesia No Tourniquet) ou anesthésie locale sur patient éveillé et sans usage du garrot a été utilisée avec succès lors du traitement des fractures du radius distal, de l’olécrane, de la rotule et de la clavicule. Cet article élargit son utilisation aux fractures bimalléolaires.
Méthodes : Nous avons réalisé une étude prospective chez 15 patients opérés pour des fractures bimalléolaires sous anesthésie locale sur patient éveillé et sans usage du garrot. Nous avons exclu de cette étude les patients âgés de moins de 18 ans, les fractures ouvertes, les fractures trimalléolaires nécessitant une fixation de la malléole postérieure, une fracture de la malléole interne associée à une fracture du col de la fibula (fracture de Maisonneuve), les patients polytraumatisés, les patients avec allergie à la lidocaïne et les patients instables. Le produit d’anesthésie a été préparé en mélangeant 50 ml de lidocaïne 1 %, 1 :100 000 d’adrénaline et 10 :1 de bicarbonate de sodium. À partir de ce mélange, nous avons pris 7 mg/kg de lidocaïne associée à l’épinéphrine pour ne pas dépasser le seuil toxique. Un total de 65 ml de cette préparation WALANT a été injecté (en sous-cutané et en sous-périosté au niveau de la malléole interne et de la malléole externe)
Résultats : En peropératoire, le score NPRS (Numeric Pain Rating Scale) a été de 0 chez tous les patients. Aucune complication locale n’a été notée, ni aucune complication due au surdosage de la lidocaïne et de l’épinéphrine.
Conclusion : La technique WALANT constitue une excellente alternative pour l’anesthésie de l’ostéosynthèse des fractures bimalléolaires. Elle présente beaucoup d’avantages, notamment pour les patients avec comorbidités et surtout dans ce contexte de pandémie liée au Covid-19 vu la diminution de l’effectif de médecins et d’infirmiers anesthésistes au bloc opératoire. La technique WALANT présente aussi un avantage significatif dans les pays en voie de développement en raison du manque de ressources financières et humaines.
Tests of reinforced concrete flight structure of the bridge through the r.Suhoy Torec in Barvenkovo

Published: April 2021

The article considers the overhaul of the reinforced concrete bridge in Barvinkove with the complete replacement of the girder structures. Beam structures were installed on existing supports, the distance between the axes of which is 14.06 m (non-standard beam). Thus, new beams must be performed on a special (individual) project. Equally important is the issue of reducing the weight of the structure, which will have a positive effect on existing foundations, reducing the pressure on the ground and, if possible, unloading the foundation of the structure. As a new girder structure, an effective construction of a reinforced concrete girder structure is presented, using perforated metal elements of box section and an effective reinforced concrete slab of the carriageway.
When designing metal blocks, a direct method of forming the parameters of the structure based on energy principles was used, namely: minimization of potential deformation energy and density distribution of potential deformation energy.
The parameters of the holes in the perforated elements at a constant pitch and the angles of inclination of the inclined lines of the beams were taken as parameters. Thus, a rational design of the blocks was obtained, which corresponded to the lowest value of potential energy, which, in turn, corresponds to the lowest material consumption, and a more uniform distribution of potential energy density with decreasing stress concentration in the corners of the holes.
Upon completion of all works, scientific and acceptance tests of the building were carried out. The test program provides for static and dynamic tests of the bridge. The aim of the study was to assess the stress-strain state metal block of reinforced concrete girder structure. During the test, the deflections of the structure were obtained, the actual distribution of deformations and stresses was revealed, the frequencies, periods and amplitudes of the natural and forced oscillations of the structure were obtained.
A theoretical model of the girder structure was built, on the basis of which the VAT components were obtained and compared with the results obtained during the test.
Influence of house bearing construction rigidi-ty of precast reinforced concrete on stress-strain state Continuous Flight Auger (CFA) piles foundations
Authors: Nosenko Viktor , Krivenko Oleg 
Published: April 2021

At present, the tendency to build multi-storey residential buildings has become widespread in Ukraine. This is due to a number of reasons: significant increase in land prices in cities, dense urban development and the availability of appropriate equipment for the construction of such structures. One of the most common materials for multi-storey buildings is monolithic reinforced concrete. The main advantage of monolithic structures is the possibility of free spatial planning and the possibility of uniform redistribution of forces in the elements of the frame - the house works as one rigid entire structure. On the other hand, such structures require a long construction time and appropriate highly qualified control of monolithic works. Therefore, as an alternative, prefabricated reinforced concrete structures are used to accelerate the pace of construction.
In this work, the influence of the rigidity of a precast reinforced concrete house on the stress-strain state of CFA piles foundation is investigated. The stress-strain state of a precast reinforced concrete building with two basement options is analyzed: precast and monolithic.

The numerical modeling of the interaction of the system elements is used as a research method: soil base - foundation - aboveground structure.
It was found that the replacement in a prefabricated house only one basement floor of precast concrete on a monolithic one affects the redistribution of forces, so the self-supporting wall is loaded 2.6 times, and the busiest wall, which rests on both sides of the floor slab, is unloaded to 2.1 times.
It was found that in the case of a basement made of precast reinforced concrete with a precast basement the difference efforts in pile heads (under the load-bearing walls) can differ 1.98 times, and in the case of a monolithic one 1.17 times. So it is mean, the monolithic foundation redistributed of efforts between the piles is more uniform.
It is established that the monolithic reinforced concrete basement, in comparison with the prefabricated one, reduces the uneven settlement of the foundation by 2.4 times.
When designing large-panel houses, it is advisable to provide a basement floor monolithic - this will allow to load the fundamental constructions more evenly, which in its reduction reduces the relative deformation of buildings and reduces their cost.

At present, in large cities, cities - millionaires, there is a tendency to build a large volume of residential multi-storey buildings entertainment complexes on undeveloped, free from construction areas of urban territory To meet the food needs of the population, it becomes necessary to create large livestock complexes. Ukraine, having a significant natural resource, has created conditions for the arrival of large international investors. That’s why in recent years, there is a renewal of material and technical agricultural base, which contributes to the revival of almost abandoned in the 90s, one of the main activities and specialization of our country - agriculture, which allows to assure the needs of the population and industry of our and neighboring countries with quality organic products and materials. In such conditions, modernization, renewal, re-equipment of not only outdated, inefficient equipment, but also production processes, and as a consequence of buildings, structures, complexes. This leads to the emergence of new engineering objects, classification, features of construction, design and operation of which need to be studied, covered in the literature, taken into account at different stages of their operation.
"Lagoons" is one of such objects. This publication presents the main definition of a special agricultural building - lagoon, presents their classification by various parameters: location, depth, shape and size in plan, in terms of interaction with the environment, by material. The main technological processes influencing the design, construction and operation of lagoons are given. The basic requirements to materials (geotextiles, geomembrane), and also the basic requirements to their storage, use and the device at creation of waterproof screens at construction of lagoons are reflected.
Stress-strain state of retaining walls depend-ing on them construction
Authors: Ruchkivskyi Vitalii 
Published: April 2021

In modern urban planning, in most cases, the construction of buildings and underground structures has a negative impact of new construction on existing buildings. As a rule, the foundations of new buildings are designed with a greater depth of laying compared to existing buildings. As a result of excavation work and subsequent installation of load-bearing structures of underground structures, existing buildings are subjected to uneven subsidence. Cracks may appear in the walls and the serviceability of structural elements may be impaired. Before the geotechnics there is a task to determine the dimensions of the zone of influence of new construction, ie the area where negative processes of stress-strain formation can occur. To comply with the safe operation of existing buildings, there is a need for a reliable forecast of additional deformations of existing buildings and structures, as well as the choice of a rational solution for the protection of the pit.
Modeling of the stress-strain state of the retaining wall of the pit with different diameters and changes in the number of rows of piles. Calculations of the stress-strain state of the protective structures together with the soil base were performed using the finite element method for a horizontal load of 1 m.p. retaining wall (the problem of flat deformation).
4 variants of the problem were solved:
V1 - retaining wall with piles 13.5 m, 420 mm in diameter, arranged in one row;
V2 - retaining wall with piles 13.5 m, 620 mm in diameter, arranged in one row;
V3 - retaining wall with piles 13.5 m, 420 mm in diameter, arranged in two rows;
V4 - retaining wall with piles 13.5 m, 620 mm in diameter, arranged in two rows;
The influence of increasing the diameter of piles in the structure of the retaining wall on the increase of the moment of inertia of the section, which leads to the perception of a greater value of bending moments, is shown.
The technical and economic comparison of the pit fencing options is performed.
The most rational solution of excavation of the pit in these conditions is revealed.

Osteonecrosis of the Jaw (ONJ) related to drugs (bisphosphonates, denosumab, antiangiogenic and other agents) is an issue of care by the “Rete Oncologica di Piemonte e Valle d’Aosta” since 2005. The “Rete Oncologica” is a cancer network that include professionals (physicians, nurses, technicians, supporting staff, data managers, etc) of all the healthcare units that manage and treat patients with cancer and hematologic disorders in two regions (Piedmont and Aosta Valley, globally 4.4 million population) in the North-Western Italy. Besides study groups, research grants and organization of meetings, in order to facilitate the awareness of ONJ issues, on 2014 the network created specific ONJ-dedicated pages on the network website www.reteoncologica.it [http://www.reteoncologica.it] . In the area for healthcare staff , the reader can find an ONJ title, that opens to a ONJ front page (http://www.reteoncologica.it/area-operatori/osteonecrosi-dei-mascellari-onj) presenting links to recent issues (recommendations, meetings, papers, etc) and to an Archive with previous contents, classified for year (http://www.reteoncologica.it/area-operatori/osteonecrosi-dei-mascellari-onj/185-documenti-e-slide) . Preliminary altmetric evaluation of the ONJ pages (number of visits; median time of stay; etc) show a variable but steady access to the ONJ contents of the website, with occasional peaks.
Developing Intercultural Communicative Competence: Formative Assessment Tools for Mandarin as a Foreign Language
Authors: DeWitt Dorothy , Chan Suet Fong 
Published: April 2021

Purpose - Intercultural communicative competence (ICC) is important in intercultural exchange, to address problems and conflicts which may arise due to miscommunication that results from interlocutorsâ€™ diverse cultural and linguistic backgrounds. Interlocutors may have different perceptions and interpretations of communicative behaviour. However, cultural and intercultural aspects seem to be ignored in teaching Mandarin as a foreign language (MFL) in Malaysian higher education institutions. Hence, the ICC level among local MFL learners is unknown. In this study, formative assessments were designed in a culturally integrated MFL module to investigate learnersâ€™ level of ICC in a selected Malaysian polytechnic. Methodology - The polytechnic was selected as cultural competency was incorporated in the MFL course. A design and developmental research was carried out to design formative assessment for ICC based on expertsâ€™ feedback. The assessment comprised Intercultural Discussion and Reflections, Cultural Discovery, Cultural Quizzes and an Intercultural Communicative Task. They were implemented to assess learnersâ€™ ICC. Findings - The results indicate that different forms of assessment were suitable for assessing the respective competences, and that multiple forms of formative assessment should be employed to assess and improve MFL learnersâ€™ ICC. Significance - Instructors in higher education could apply these forms of formative assessment to develop ICC among their MFL learners. The assessments could also be extended to intercultural communication competence development in other languages, which is important in a multicultural and globalized society.
