Introduction : Les troubles neurologiques précoces du nouveau-né à terme sont peu documentés en Côted’Ivoire, en dehors de l’asphyxie périnatale. L’objectif était de déterminer leur prévalence et de décrire leur profil épidémiologique et clinique ainsi que leur prise en charge au centre hospitalier universitaire de Yopougon à Abidjan.
Patients et méthodes : L’étude transversale et descriptive a porté sur 406 nouveau-nés à terme hospitalisés en néonatologie, âgés de 72 heures au plus et présentant des troubles neurologiques à l’admission.
Résultats : La prévalence était de 53,1 %. Le profil épidémiologique était celui d’un nouveau-né à terme de sexe masculin (sex-ratio de 1,75), référé d’une maternité périphérique (77,8 %), dans un délai de plus de 24 heures (40,8 %). Sur le plan clinique, il y avait un risque anoxique dans 89,8 % des cas et un risque infectieux dans 32,4 %. Le score d’Apgar était inférieur à 7 à la cinquième minute chez 62,8 % des nouveau-nés. Les troubles neurologiques étaient dominés par les anomalies des réflexes archaïques (91,9 %) et du cri (84,9 %). La prise en charge était marquée par le retard à l’admission chez les nouveau-nés outborn et l’insuffisance des moyens diagnostiques et thérapeutiques.
Conclusion : Mener des actions au niveau périphérique, pour réduire le retard de transfert vers le centre de référence et au niveau central, pour améliorer la prise en charge.
Development of blocking compositions with a bridging agent for oil well killing in conditions of abnormally low formation pressure and carbonate reservoir rocks
Authors: Mardashov Dmitrii 
Published: December 2021

Production well killing before workover operations in late-stage oil and gas-condensate fields can be complicated by abnormally low formation pressure, carbonate type of reservoir rocks, and high gas-oil ratio. These complications lead to the intensive absorption of technological fluids by the formation and gas ingresses, which, in its turn, increases the time of killing wells and putting them on production, reduction of productivity, and additional costs. Therefore, it is crucial to develop a high-performance well-killing composition that would allow improving the efficiency of killing wells in complicated geological, physical, and technological conditions at the expense of reliable overlapping of the perforation interval (or open wellbore) to prevent gas intakes and gas outflow from the formation. To develop blocking compounds, a set of laboratory tests has been carried out, including physical and chemical (determination of density, viscosity, thermal stability, sedimentation stability, etc.) and research of blocking and filtration properties of compositions during simulation of a fractured reservoir. In the course of laboratory tests, the choice of fractional composition and polymer filler concentration was substantiated in the blocking emulsion and polymer compositions to increase the efficiency of their application under the complicated conditions of killing oil wells. As a result of laboratory research and field tests, the emulsion and polymer blocking compositions containing bridging agent (microcalcite) were developed, which increase the oil well killing efficiency by preventing the absorption of technological fluids in the formations and, as a result, preserving its productivity.
CHAOTIC COMPRESSIVE SENSING OF TV –UHF BAND IN IRAQ USING CHEBYSHEV GRAM SCHMIDT SENSING MATRIX
Authors: Abed Hadeel S. , N. Abdullah Hikmat 
Published: December 2021

Cognitive radio (CR) is a promising technology for solving spectrum sacristy problem. Spectrum sensing is the main step of CR. Sensing the wideband spectrum produces more challenges. Compressive sensing (CS) is a technology used as spectrum sening in CR to solve these challenges. CS consists of three stages: sparse representation, encoding and decoding. In encoding stage sensing matrix are required, and it plays an important role for performance of CS. The design of efficient sensing matrix requires achieving low mutual coherence . In decoding stage the recovery algorithm is applied to reconstruct a sparse signal. İn this paper a new chaotic matrix is proposed based on Chebyshev map and modified gram Schmidt (MGS). The CS based proposed matrix is applied for sensing real TV signal as a PU. The proposed system is tested under two types of recovery algorithms. The performance of CS based proposed matrix is measured using recovery error (Re), mean square error (MSE), and probability of detection (Pd) and evaluated by comparing it with Gaussian, Bernoulli and chaotic matrix in the literature. The simulation results show that the proposed system has low Re and high Pd under low SNR values and has low MSE with high compression.

Authors: Xia Zhengbing , Duan Xiaofang 
Published: December 2021

In order to promote the application of steel fiber recycled concrete in projects such as roads and bridges, 25 groups of steel fiber recycled concrete with different mix proportions were designed, taking the replacement rate of recycled aggregate and the volume fraction of steel fibers as experimental parameters, and 77 steel bars and steel fiber recycled concrete bonded specimens were made and pasted with strain gauges for the pull-out test. The research results showed that the greater the replacement rate of recycled aggregates was, the lower the bond strength between steel bars and steel fiber recycled concrete was; in the range of 0~1.2%, the higher the mixing amount of steel fibers was, the greater the bond strength of the specimen was; in the range of 0~1.6%, the higher the mixing amount of steel fibers was, the greater the slip value of the specimen under the peak load was; the addition of steel fibers improved the failure behavior of the recycled concrete pull-out specimens; the test specimens mainly had pull-out failure when the mixing amount of steel fibers was 1.2% and 1.6%. Finally, this study modified the bond-slip constitutive relationship model of steel and steel fiber recycled concrete, analyzed the influence of the replacement rate of recycled aggregate and the mix proportion of steel fibers on its bonding performance, and compared the results with the test results. The results demonstrate that the test curve is in good agreement with the fitted curve, which can provide theoretical support for engineering applications.

Published: December 2021

In this research, the finite element method is used to develop a numerical model to analyse the effect of the external strengthening of reinforced concrete beams by using carbon Fiber Reinforced Polymer (CFRP) sheets. A finite element model has been developed to investigate the behavior of RC beams strengthened with CFRP sheets by testing nineteen externally simple R.C. beams, tested under a four-point load setup until failure. Various CFRP systems were used to strengthen the specimens. The numerical results using the (ANSYS workbench v.19.1) were calibrated and validated with the experimental results. The research results indicate a significant improvement in the structural behavior of the specimens strengthened using CFRP sheet systems. Then the validated model investigated the effect of the width of CFRP sheets, no of layers, and CFRP size on the behavior of strengthened R.C. beams. Results of this numerical investigation show the effectiveness of increase CFRP width to improve the flexural capacity of R.C. beams. An increase in the flexural capacity up to 100 % compared to the control beam.

Authors: Agag Fatma , Ahmad Seleem S. E. , Sallam Hossam El-Din M. 
Published: December 2021

The present experimental study includes testing thirteen reinforced concrete beams with openings at different locations to investigate the efficiency of strengthening such openings. Different strengthening techniques around the opening after and before casting include diagonal bars, upper and lower steel, and carbon fiber reinforced polymers (CFRP), were examined. All beams were made from 30 MPa compressive strength and tested under four-point loading. The cross section of the beams is 400 mm depth x 160 mm width and beam length 2400 mm. The dimensions of the opening are 200 mm x 200 mm. The stiffness, deflection, failure load, and failure mode of the strengthened beams were discussed. Experimental results showed that the beams strengthened with upper and lower steel around opening at mid-span increase the load-carrying capacity by 16.59%. However, beams strengthened by CFRP sheets around the opening in the shear zone increase the load carrying capacity by 47.7% compared to opened beam.

In the article on the basis of the former general-methodical basis where the methodology of construction developer and digital administration by construction organizations is combined; scientific and applied bases of VIM-technologies; "Geometric econometrics"; modern methods of formalized modeling and adjustment of the cycle of development projects; the latest approaches to the formation of organizational structures for the management of construction production with the involvement of digital technologies. The methodological basis of the study was based on a productive combination of visual and graphical capabilities of BIM-technology, digital control technologies, methods of graph-analytical visualization (provided through the use of "geometric econometrics"). The resulting methodological apparatus allows the use of BIM-technologies in the organization of construction in fundamentally new positions - not only as a means of graph-analytical structuring of physical volumes of contract work, but, above all, as a modern basis for variable organizational and technological modeling of works and stages of construction. project and as a tool for managing the cycle and environment of the development project.
It is substantiated and proved that when forming the analytical basis of the construction enterprise in modern digital space it is expedient to take into account the vector of improvement of management models in the direction from single-purpose to multi-purpose, from deterministic to deterministic-stochastic, from worc-arc model (robot-arc). to the model of the synthetic type “worc & matrix” “work & top”. The successful operation and development of construction organizations participating in projects in the digital environment requires a sound approach to the formation of their competitive strategy as executors. The article highlights that the concept of competitive strategy of the contractor is a set of rules and techniques that should guide the construction organization, ready for change in its activities through the involvement of digital management format: integral elements of the process of digital transformation in construction are changes in activities of construction organizations, which consist in a full-scale digital transformation based on the company's digital development strategy. Implementing the measures envisaged by the digital strategy requires an integrated approach that includes the company's development in various areas, but understanding the trends of the digital environment and construction market will allow companies to rationally use existing digital potential and effectively identify ways to further digital development of construction companies.
“Flemish Legends” by Charles de Coster. The Peculiarities of the Traslations into Dutch
Authors: Zhuravleva O. M. , Ulianitckaia L. A. , Shumkov A. A. 
Published: December 2021

Introduction. Charles de Coster's “Flemish Legends” were published in 1858 in French. With the growth of the national consciousness of the Flemings, this book, having particular artistic and cultural meaning, had to be translated, anyhow, into the Flemish variant of Dutch. There have been several translations, which differ significantly. To understand the specifics and success of a particular translation, it is necessary to analyze the cultural-linguistic and socio-political circumstances of its creation, to study the personalities of the translators, their artistic biographies, and also to assess the impact of the culture-forming factors.Methodology and sources. The research methodology is based on the descriptive method. At that we take into account a lot of linguistic, historical, social and cultural variables. As a study material two translations of “Flemish Legends” into Dutch (1917 and 1998) are chosen, as well as several sources describing the history of Belgium after 1830. For collating the translations the comparative method is used, taking into account the lexical, grammatical and stylistic features of the analyzed texts.Results and discussion. Charles De Coster, being a bilingual, preferred the French language. This can be explained by his desire to make folklore an asset of the upper social class, mainly bilinguals and francophones, upon these legends being already known among the Flemings. In addition, for the proper resonance, it was more profitable to publish the book in French. It can also be assumed that the legends were collected throughout Flanders; therefore, there were significant dialectal differences and problems for choosing a unified version of the Flemish language. To convey the medieval flavor, Charles de Coster used a deliberately archaized language. At the beginning of the 20th century S. Streuvels created a specific translation, more reminiscent of calque from French and preserving the features of the original text. At the end of the 20th century, W. Spillebeen translated the French text into a modern language, which was not the Belgian Dutch, but the standard Dutch.Conclusion. The translations discussed are quite different. S. Streuvels retained the style and structure of the original text, so his work was difficult for perception even by his contemporaries, and today the translation has become practically unreadable. W. Spillebeen tried to translate the legends into a modern language, bringing the structural components in line with the modern norm and preserving only the most necessary archaisms. Nevertheless, the text of the “Flemish legends” in the Belgian Dutch does not exist: they are written either in dialects, or in the “Frenchified” Dutch, or in the standard Dutch.
K.M. Takhtarev is one of the First Professional Sociologists in Russia. To the 150th Anniversary of His Birth

Published: December 2021

Introduction. The article presents the fate and work of the famous Russian sociologist Konstantin Mikhailovich Takhtarev (1871–1925), who would have turned 150 years old in 2021. He was one of the first professional sociologists who played an important role in the institutionalization of Russian sociology. His works and other deeds are still not fully comprehended and, therefore, are insufficiently used in research and in the process of training sociologists. The article presents the main results of his work and the direction of his activities in organizing sociological knowledge in Russia.Methodology and sources. The article implements a historical and biographical approach combined with a comparative analysis of the life and scientific fate of the famous Russian sociologist K. M. Takhtarev, professor of the St Petersburg University (1911–1925). His main works and the results of his activities on the institutionalization of Russian sociology are analyzed.Results and discussion. The name of K.M. Takhtarev stands next to such names as M.M. Kovalevsky, N.I. Kareev, A.S. Lappo-Danilevsky, E.V. de Roberti, P.A. Sorokin, etc. His contribution to the institutionalization of Russian sociology is very significant. He was one of the first to prepare complete textbooks, created his own system of sociology (P. Sorokin), was one of the organizers of the M.M. Kovalevsky Russian Sociological Society, which confirmed the formation of the Russian sociological community. The creation of the country's first sociological institute is associated with his name. N.I. Kareev called him and P.A. Sorokin the first professional sociologists of Russia. The article shows his understanding of the subject of sociology, the basic concepts that reveal the essence of social life, its evolution, through the stages of self-sufficiency – the foundations of his theory. The significance of the systematization of sociological ideas carried out by him, which formed the basis of his system of sociology, is revealed. The role of Takhtarev in the development of genetic sociology as a sociological direction studying the dynamics of forms of society and social institutions is emphasized.Conclusion. The significance of K.M. Takhtarev's ideas for today's sociology is shown and it is argued that it is necessary to refer to his works today. The special relevance of the logic of building his own system of sociology, research experiments in the field of genetic sociology, the substantiation of social laws and the classification of social laws are emphasized.

Distribution of Corneal Geometric Landmarks and Relationship Between Their Distances and Biomechanical Parameters in the Development of Keratoconus
Authors: Tian Lei , Zhang Hui , Guo Li-Li , Qin Xiao , Zhang Di , Li Lin , Wu Ying , Jie Ying , Zhang Haixia 
Published: December 2021

Purpose: To analyze the changes in coordinates and distances among three typical geometric landmarks of the cornea, namely, the thinnest point (TP), maximum curvature (Kmax), and corneal apex (AP) during the development of keratoconus, and explore the potential relationship between these changes and the abnormalities of corneal biomechanics.Methods: Normal eyes (n = 127), clinical keratoconic eyes (CKC, n = 290), and the eyes of forme fruste keratoconus (FFKC, n = 85) were included; among them, the CKC group was classified into four grades based on the Topographic Keratoconus Classification (TKC) provided by Pentacam. A total of 38 Corvis ST output parameters and three distance parameters of three typical landmarks (DKmax-AP, DTP-AP, and DKmax-TP) based on Pentacam were included. The differences of parameters among the abovementioned six groups (Normal, FFKC, and CKC stage I to CKC stage IV) were analyzed. Spearman’s rank correlation test was performed to choose several dynamic corneal response (DCR) parameters that could best reflect the changes of corneal biomechanical characteristics during the progression of the disease, and the Pearson’s or Spearman’s correlation test was conducted to determine the association between the three distances and the selected DCR parameters in each grade. In addition, by flipping the X coordinate of the left eye on the vertical axis to reflect the direction of the right eye, the coordinates of TP and Kmax in different developmental grades were highlighted.Results: From CKC stage II, the three geometric landmark distances commenced to correlate with the corneal DCR parameters (CBI, SPA1, IR, DA Ratio 2, ARTh, MIR, Radius, Pachy, and DA Ratio 1), which could better represent the changes of biomechanical properties from normal cornea to keratoconus. From normal cornea to CKC stage IV, the coordinates of Kmax were gradually tended to the inferior temporal region from dispersion, while TP was always concentrated in the inferior temporal region. Although DKmax-AP, DKmax-TP, and DTP-AP all showed a gradual decreasing trend with the progress of the disease, the first two did not change significantly, and only DTP-AP significantly approached AP in the later stage of disease development. In addition, from the FFKC group, the corresponding values of DKmax-TP in each disease development group were smaller than DKmax-AP.Conclusions: In the later stage of keratoconus, the relationship between the three typical landmark distance parameters and DCR parameters is stronger, and even the weakening of corneal biomechanical properties may be accompanied by the merger of typical landmark positions.
