A sample size of 200 subjects was chosen from 10 high schools in the Frontier Region Kohat (FR Kohat). A questionnaire of five points likert scale after in quest of due authorization from heads of institutions was used to reach to the in facet of the recognizable truth. Arithmetical technique Mean, Percentage and Standard Deviation were run to inspect the collected records. The pollster analyze the link of sports and co-curricular contribution and its optimistic role to enhance educational performances of secondary schools students as to increase grade point average GPA. Sports and Co-curricular activities have optimistic outcome on students’ management. Those student who chip in in co-curricular activities show good performance. When learners execute these activities fruitfully and appropriately they are awarded for their first-class concert and manners and thus they take conceit on their achievement. Due to these achievement, they haul off additional, they gain improved self-confidence, poise and self-honor. Finally it was concluded that involvement in sports and co-curricular activities have an imperative result on students accomplishment score and other related activities. They achieve higher GPAs higher score in colleges admittance trial, better turnout, squat failure tariff and good physical condition performance. Furthermore schools are faced budget problems. Most of heads of institutions are not interested in sports and co-curricular activities. Most of teachers and parents consider these activities as wastage of time. Facilities are not available for students. Stuents play on their own risk because proper security are not available for partakers. Students need proper nutrition but unfortunately balance diet not available for them.

The study was geared toward determining the factors embedded in “hidden curricula” in an online learning environment of a physical education teacher education program. This qualitative-descriptive study considered a complete enumeration of the Bachelor of Physical Education students from a state university in Pampanga, Philippines who voluntarily participated in this qualitative investigation (n = 135) by responding to structured and open-ended questions. Aided by Thematic Analysis, findings revealed six emerging themes that described the embedded hidden curricula in the online learning environment, namely: contributory factors in an online learning experience (OLEx); educational opportunities in the new normal learning set-up; unfavorable factors in using online learning environment; and proposed inputs in enhancing the teaching-learning process in an OLEx. The implications derived as an outgrowth of the identified positive and negative factors as expressed by the participants provided a conceptual understanding of the contemporary picture of the hidden curricula and how it would define the future of an effective online learning experience.

Published: May 2022

In school, there are a lot of lesson, skills and  experiences that may took place. It is inevitable to encounter unexpected certainties during class hours, especially during Physical Education classes. There are a lot of unexpected certainties like injuries that may took place, the latter may deprove the students in attaining the knowledge and skills they may acquired during their physical education classes. Moreover, it is the teacher's primary role to keep the students safe from any harm. Thus, this study aimed to assess the knowledge and readiness of Filipino Physical Educators in addressing injuries in Physical Education settings. This mixed-method sequential explanatory research considered twenty (20) physical educators of a state-funded higher education institution were selected for the quantitative phase. Four (4) of them were selected in the qualitative phase via extreme case sampling that measured their demographic profile, knowledge, readiness, and experiences in first aid management. Using the Pearson r test manifests a negative relationship between the variables of this study and the demographic profile of the respondents/participants. As per the  results of the quantitative phase and the findings of the qualitataive phase this study delineates that the Physical Educators do have a sufficient level of knowledge and readiness in terms of addressing and responding to unexpected certainties that may took place on their respective physical education classes. Furthermore, it is recommended that Physical Educators must consider a variety of strategies to improve their knowledge and readiness in dealing with injuries. With this, further knowledge and information should be obtained to strengthen and enhance the knowledge and readiness they initially have.
Pushing Optimal ABox Repair from EL Towards More Expressive Horn-DLs: Extended Version
Authors:   Technische Universität Dresden, Baader Franz , Kriegel Francesco ,   Technische Universität Dresden
Published: May 2022

Ontologies based on Description Logic (DL) represent general background knowledge in a terminology (TBox) and the actual data in an ABox. DL systems can then be used to compute consequences (such as answers to certain queries) from an ontology consisting of a TBox and an ABox. Since both human-made and machine-learned data sets may contain errors, which manifest themselves as unintuitive or obviously incorrect consequences, repairing DL-based ontologies in the sense of removing such unwanted consequences is an important topic in DL research. Most of the repair approaches described in the literature produce repairs that are not optimal, in the sense that they do not guarantee that only a minimal set of consequences is removed. In a series of papers, we have developed an approach for computing optimal repairs, starting with the restricted setting of an EL instance store, extending this to the more general setting of a quantified ABox (where some individuals may be anonymous), and then adding a static EL TBox. Here, we extend the expressivity of the underlying DL considerably, by adding nominals, inverse roles, regular role inclusions and the bottom concept to EL, which yields a fragment of the well-known DL Horn-SROIQ. The ideas underlying our repair approach still apply to this DL, though several non-trivial extensions are needed to deal with the new constructors and axioms. The developed repair approach can also be used to treat unwanted consequences expressed by certain conjunctive queries or regular path queries, and to handle Horn-ALCOI TBoxes with regular role inclusions.

Published: May 2022

Despite the increasing automation of workflows for the preparation of systems for molecular dynamics simulations, the custom editing of molecular topologies to accommodate non-standard modifications remains a daunting task even for experienced users. To alleviate this issue, we created Gromologist, a utility library that provides the simulation community with a toolbox of primitive operations, as well as useful repetitive procedures identified during years of research. The library has been developed in response to users’ feedback, and will continue to grow to include more use cases, thorough automatic testing and support for a broader spectrum of rare features. The program is available at gitlab.com/KomBioMol/gromologist and via Python’s pip.

Published: May 2022

In this research, a selective, cost-efficient, highly sensitive Ag nanostructure Surface Enhanced Raman Spectroscopy (SERS) sensor was developed as a methodological approach to rapidly detect a targeted-ss-DNA (stx2) in STEC (Shiga toxin-producing Escherichia coli). The Ag nanostructure-based SERS substrate was functionalized by two type of thiols: thiol-ss-DNA for bonding targeted-ss-DNA and 6-Mercapto-1-hexanol (HS(CH2)6OH) for blocking the Ag nanostructure surface. Methylene Blue (MB) was used as a Raman marker to quantify targeted-ss-DNA, as well as a model molecule to characterize the electrodeposited Ag nanostructure SERS substrate. Ag nanostructure SERS substrates showed good sensitivity and repeatability towards MB detection, with a LOD = 0.3158 μM, RSD = 12.48% (at 45 different random points). More importantly, the Ag nanostructure/ss-DNA SERS substrate showed good selectivity towards STEC O157 stx2 targeted DNA, as well as good linearity and sensitivity towards its detection in a buffer solution. A limit of detection of 0.4900 aM in a wide linear range from 1 aM to 100 pM was demonstrated. The SERS sensors were able to identify target DNA ( stx2) in an STEC strain and the study showed proof of principle that SERS substrate has potential as a cost effective, highly selective, highly sensitive DNA and bacteria sensor without the aid of DNA amplification. With further development and validation, this methodological approach has the potential for use in the point-of-use detection for instance on a farm or in the food industry.

Published: May 2022

Precisely regulating the chemoselectivity of free radicals and inhibiting their side reactions has always been one of the most difficult challenges in organic chemistry. Based on the full utilization of stability and philicity of free radicals, we have achieved a Radical-involved Paired Electrochemical Cascade Reaction (RPECR), which is also the first example of catalyst-free direct hydroxyarylation of unactivated benzylic carbon (sp3/sp2/sp). In detail, transient benzylic radical species generated by direct anodic oxidation of inexpensive and readily available alkyl/alkenyl/alkynylbenzenes undergo cascade transformations to couple with persistent radical anion obtained from cathodic reduction, yielding the large steric hindered high-value-added secondary and tertiary benzylic alcohols. Mechanistic studies, including divided-cell experiments, isotope labeling, free radical trapping, electron paramagnetic resonance (EPR), reaction kinetics, and cyclic voltammetry, strongly support the proposed RPECR process. Gram-scale synthesis and diversification of drug derivative have visualized the tremendous potential of this protocol for practical applications.
Probing local changes to α-helical structures with 2D IR spectroscopy and isotope labeling
Authors: Webb Kelsey , Hess Kayla , Shmidt Alisa , Segner Kathryn , Buchanan Lauren
Published: May 2022

α-helical secondary structures impart specific mechanical and physiochemical properties to peptides and proteins, enabling them to perform a vast array of molecular tasks ranging from membrane insertion to molecular allostery. Loss of α-helical content in specific regions can inhibit native polypeptide function or induce new, potentially toxic, biological activities. Thus, identifying specific residues that exhibit loss or gain of helicity is critical for understanding the molecular basis of function. Two-dimensional infrared (2D IR) spectroscopy coupled with isotope labeling is capable of capturing detailed structural changes in polypeptides. Yet, questions remain regarding the inherent sensitivity of isotope-labeled modes to local changes in α-helicity, such as terminal fraying; the origin of spectral shifts (hydrogen bonding vs. vibrational coupling); and the ability to definitively detect coupled isotopic signals in the presence of overlapping sidechains. Here, we address each of these points systematically by characterizing a short, model α-helix (DPAEAAKAAAGR-NH2) with 2D IR and isotope labeling. These results demonstrate that pairs of 13C18O probes placed three residues apart can detect subtle structural changes and variations along the length of the model peptide as its α-helicity is tuned. Comparison of singly and doubly labeled peptides affirmed that frequency shifts arise primarily from hydrogen bonding, while vibrational coupling between paired isotopes leads to increased peak amplitudes that can clearly be differentiated from underlying sidechain modes or uncoupled isotope labels that do not participate in helical structures. These results demonstrate that 2D IR in tandem with i,i+3 isotope-labeling schemes can capture residue-specific molecular interactions within a single turn of an α-helix.

Currently, our country is showing a gradual decline in the rate of traffic accidents, but when compared internationally, it is ranked 24th, the lowest among 24 countries, with more than twice the average number of traffic accidents per 100,000 people in OECD member countries. As such, it can be seen that the current status of traffic accidents in Korea is very serious. In addition, despite entering an aging society, the number of traffic accidents for the elderly aged 65 or older in Korea is about three times higher than the average of OECD member countries, and traffic accidents for the elderly are seriously occurring. Therefore, this study examines the distribution of traffic accidents among the elderly and children, and uses the Geographic Information System (GIS) to analyze whether the senior protection zone is appropriately designated compared with the children protection zone. As a result of the analysis, it was found that almost all areas of child traffic accident and children protection zones were designated appropriately as they matched, while most areas of elderly traffic accident and senior protection zones were not matched. Therefore, through this study, it was confirmed that elderly traffic accidents occur frequently, but senior protection zones are very insufficient. Based on this, legal and policy suggestions were discussed to prevent traffic accidents in the elderly and to deterrence and control drivers' violations of laws.
Low income renters and housing supports

Published: May 2022

Rental affordability challenges for low-to-moderate-income groups have been well documented. Changes to housing supports in recent years, notably the rapid expansion of Housing Assistance Payment (HAP), aim to address affordability challenges for low-income households in the rental sector. Within this context, this report seeks to inform our understanding of the current system of housing supports for low-income renters in Ireland. The report examines tenure patterns and rental affordability. It reviews the range and design of housing supports available to low-income renters and examines how the localised operation of differential rent schemes, which determines supported tenants’ contributions, affects the level of and variation in support received. With the increased reliance on the provision of indirect housing supports (through rental subsidies or supplementary income supports), it also examines the availability of accommodation for low-income renters within the private rental sector. Housing supports – by virtue of being means-tested – affect the financial incentives individuals have with regards to being in paid work or working an additional hour. This report uses SWITCH, which is the ESRI’s tax and benefit microsimulation model, to analyse the impact of these supports on the effective tax rates faced by low-income renters: a key consideration for any means-tested supports.
Quasi-zero rigidity condition for static force characteristic of parallelogram mechanism for seat vibration protection system
Authors: Korytov M. S. , Kashapova I. E. , Shcherbakov V. S.
Published: May 2022

Introduction. Reducing vibration effects on machine operators is an urgent task; it allows to minimize the impact of vibrations on health, increase efficiency and attention. Accuracy and productivity can be improved. The problem of vibration protection is relevant for all types of machines, the working bodies of which interact with the soil and road surface. One of the impact reduction directions, along with vibration protection of cabs, is the development of vibration protection systems for operator seats. It is promising to use the effect of quasi-zero rigidity, which makes it possible to effectively damp low-frequency oscillations. For the proposed design based on a parallelogram mechanism, it is necessary to determine the condition for the horizontalness of the middle section of the static power characteristic.Materials and Methods. For the developed design scheme, using well-known power static and geometric relationships, novel analytical relationships between the parameters of the initial data and the vertical lifting force of the mechanism were derived. The initial parameters include the linear dimensions of the mechanism, the size of the quasi-zero rigidity zone, the weight of the chair with the operator, and the spring stiffness. When deriving analytical dependencies, the coordinates of the points of the mechanism moving and stationary relative to their own base were used.Results. The use of the developed analytical dependencies allows, for the given parameters of the initial data, to build a static power characteristic of the mechanism. The middle section of the characteristic is close to horizontal, but in general it is not horizontal. As an example, a static characteristic is given for a set of initial data values, the middle part of which is not horizontal. Equating the values of the vertical force of the mechanism at the left and right boundary points of the middle part of the characteristic made it possible to determine analytical dependences for ensuring quasi-zero rigidity.Discussion and conclusions. The obtained analytical expressions for ensuring the horizontalness of the middle section of the static power characteristic were verified. Applying the derived conditions decreases the number of parameters in the original data by one. An increase in the two dimensional parameters of the mechanism significantly reduces the required rigidity of the mechanism spring, which reduces the metal consumption.
Pure pursuit method use to control unmanned motor grader
Authors: Sukharev R. Yu.
Published: May 2022

Introduction. A relevant objective of implementing the advanced systems of self-driving road construction vehicles can be accomplished by mathematical modelling. One of the important issues when creating a motion control system for a self-driving vehicle is to develop a trajectory following algorithm. The most well-known method of following the trajectory is a pure pursuit method, which is successfully used to control the movement of mobile robots.Materials and methods. Hence, the research objective has been defined and is to adapt the pure pursuit method to control an autonomous grader. To achieve the research objective, the task of a mathematical model of the motor grader movement with front steering wheels has been developed, and a mathematical model of the motor grader motion control system has been compiled. Besides, we propose an integral criterion to evaluate the efficiency of the motion control system of a unmanned grader. Some theoretical studies of the mathematical model have been carried out and the dependencies of the integral criterion on the design and operational parameters of the grader, as well as on the parameter of the control method (visibility range) have been obtained. Moreover, the optimal values of the visibility range for various values of the base length, base coefficient and machine speed have been defined according to the proposed efficiency criterion.Results. As a result of approximating the obtained optimal values, the pure pursuit method has been modified to control a self-driving motor grader, taking into account its design features and travel speed. The results obtained can be used to create the prototypes of unmanned control systems for road construction vehicles.

Published: May 2022

Introduction. This article is devoted to the problem of determining the territorial (pedestrian) accessibility of stopping points in large cities, which is one of the indicators of the quality of transport services for the population.The aim of the study is to develop a methodology for determining the territorial (pedestrian) accessibility of stopping points of a large city with a thousand or more stopping points, based on publicly available data. The cause of the study was the dificulty of solving this problem, due to the large number of both stopping points and residential facilities, the straightforwardness of the shortest pedestrian approach, the lack of detailed instructions for performing calculations, etc. Based on the review of Russian and foreign scientific sources, approaches to determining the territorial accessibility of stopping points were considered, taking into account various additional parameters, such as the number of routes passing through a stopping point, the intensity of passenger exchange, the availability of socially significant objects, etc. The existing difficulties and peculiarities in determining the availability of stopping points for individual and multi-apartment residential buildings are given. In the framework of the System-wide measures for the development of road facilities federal project and the Safe and high-quality roads national project when preparing an application for the purchase of passenger transport rolling stock for Omsk, the authors carried out scientific and practical work, as a result, a methodology has been developed to overcome some difficulties in determining the transport accessibility of stopping points in a large city by using a partially automated approach at its individual stages.Materials and methods. In particular, tools such as Yandex Map Designer, Table Excel Editor, Xtools Add-in for Excel, QGIS program, Macro in Excel using JavaScript API and HTTP geocoder were used.Results. The calculation of territorial accessibility of stopping points using the developed methodology was carried out for Omsk. The application of this technique allows to reduce labour intensity of calculations up to 10 times. Discussion. The discussion of the results presented guidelines for further improvement of the developed methodology

Authors: Jiang H.
Published: May 2022

Introduction. The article considers the possibility of forming a traffic optimization strategy based on a macroscopic fundamental diagram between urban areas. The zones of influence are constructed with the maximum and minimum values of border control, respectively, according to the category of different types of the zone of influence. The stability zones were formed by connecting the zones of influence and their shape changes with different values of exogenous flow and endogenous flow were analysed.

Materials and methods. The data on the traffic flow of the central part of the Jinan (PRC) road network are presented and an urban bizonal system is constructed using the obtained macroscopic fundamental diagrams. The modelling of the state of traffic flows was carried out and the regularity of their changes at different parameters of border control was obtained using the mathematical modelling MATLAB complex.

Results. As a result of the study, the traffic management solutions were obtained for the relatively parameter of completed and incomplete trips. The generalized options for optimizing traffic in the considered urban areas are proposed – four combinations of strategies for traffic management are performed serving the design optimization option with different traffic flow conditions.

Discussion and conclusions. For each multi-zone system of the road network, it is necessary to form its own characteristic variant of optimizing the traffic flow.
Protection against progressive collapse of buildings with precast reinforced concrete floors
Authors: Krasnoshchekov Yu. V.
Published: May 2022

Introduction. The results of the studies analysis on the protection of multi-storey buildings from progressive collapse are presented, which indicates insufficient attention to structural systems made of precast reinforced concrete, as a result of which design standards orient the designer to the use of not always effective monolithic structures. In particular, the problem of protection against progressive collapse with the exclusion of prefabricated crossbars of floors and coatings has not been practically studied. The purpose of the study is to develop a method for calculating a continuous system of hollow plates made by the method of formless molding.

Materials and methods. When designing the protection of multi-storey buildings from prefabricated elements, a static calculation is usually carried out with the exception of vertical structures (walls, columns) and the reinforcement of floor crossbars and coatings by ensuring their continuity. There are constructive methods of reinforcing prefabricated floors by creating continuous plates of adjacent spans with the help of connecting elements made of plastic reinforcing steel, but the calculation of such systems has not been developed. A method for calculating a system of two plates according to a rigid thread scheme is proposed.

Conclusions. Currently, theoretical methods have been developed to solve various problems of protecting buildings and structures from progressive collapse. However, there are many design requirements for the protection of multistorey buildings from progressive collapse, which have not yet received experimental and theoretical confirmation for the effective solution of practical problems. It seems that in this article one of these problems is partially solved.
Concrete as a factor in reinforced concrete buildings collapse in Burundi
Authors: Mikerego E. , Ndikumana J.
Published: May 2022

Introduction. This paper presents the results of the assessment in-situ of the involvement of the concrete in the collapse of reinforced concrete buildings in Burundi.

Materials and Methods. The study consisted in the identification of the compressive strengths of the concrete structural elements of the reinforced concrete buildings under study. The compressive strengths were identified on the columns, beams and slabs using an industrial SCHMIDT 2000 sclerometer according to the protocol described in NF EN 12504-2(2003). Seventeen (17) three-storey buildings under construction were studied. For each building involved in the study, the reinforced concrete bearing elements of the first floor were studied. The results obtained were classified according to the cement grades (32.5) and (42.5) that were used in the studied buildings. A comparison of the compressive strengths obtained in-situ was established in relation to the normative values according to the cement grade used. The reliability of the obtained results was confirmed by the correlation between the results obtained in the laboratory conditions on the reinforced concrete experimental samples.

Results. This study showed that in Burundi up to 100% of collapses are caused by privately built structures. It was proved that the compressive strengths of 100% of the columns, 82% of the beams and 82% of the slabs that were made with a low-grade cement (32.5) had compressive strengths lower than the normative value (25MPa). In addition, the compressive strengths of 50% of the columns, 50% of the beams and 84% of the slabs made with a high-grade cement (42.5) were also proved to have compressive strengths lower than the normative values (35MPa).

Discussion and conclusion. In this study, the reliability of the results obtained by sclerometer test in-situ on the reinforced concrete buildings has been proved. Concrete has been shown to be a factor in the collapse of privately built reinforced concrete buildings in Burundi. Low-grade cement was observed to have a high impact in the collapse of reinforced concrete structures than the high-grade one. Therefore, as a recommendation, the process of building reinforced concrete buildings in Burundi needs to be regulated and controlled.
Shake Up: Post Disaster Housing in Nepal
Authors:   , Jeram Hemisha
Published: May 2022

Shaking tables have been used by civil engineers, to help understand the relationship between building structures and seismic behaviour since the 1960s (Bairrao et al. 1999). They are used to determine the responsibilities and characteristics of structural materials’ under seismic loads. Furthermore, they are a realistic and clear response indicator of geotechnical problems during an earthquake (Alaie et al. 2018). Research indicates there is little to limited use of these in the architectural design purposes. This thesis will review the concept use of the new Quanser Shake Table II for architectural design at the Faculty of Architecture and Design Innovation, Te Herenga Waka – Victoria University of Wellington, in addition to a structural tool for civil engineering. In this thesis, the concept of the new Quanser Shake Table II being used for architectural design is investigated with specific reference to post-disaster housing in Nepal. The literature and case studies on Nepalese house design are reviewed with the objective of bridging the gap between traditional building methods and modern seismic codes. Additionally, the aftermath of the magnitude 7.8 Gorkha Earthquake, which occurred on 25th April 2015, is evaluated to identify gaps in the current research and rebuild of Nepal. Following the Literature Review and conversations with the Nepalese community based in New Zealand, several design options were tested on the Quanser Shake Table II. The models were modified in response to the results of the initial testing. The results from testing the various models on theShaking Table were used to determine whether it can be used as a design tool for post-disaster housing.

The target population was members of this Islamic Microfinance Institution. Data from 2015 to 2018 in the Central Java Sharia Office was used to obtain a sample size of 14 from 21 BTMs. Multiple Regression Analysis was then applied to analyze this data and explain the relationship between variables. The results showed that independent variables, including CAR, NPF, and BOPO ratios are positively correlated with ROA (Return on Assets) of BTM, except FDR. Information technology system moderation variables including FDR_SYSTEM and BOPO_SYSTEM significantly and positively affect ROA, while CAR_SYSTEM and NPF_SYSTEM are negatively correlated with the returns on total assets of the institution. In general, BTM should use I.T. for excellent performance and join academics and other stakeholders to increase awareness of the benefits of these computer-based systems in Islamic Microfinance institutions.

The nonlinear static response of a vertically oriented coupled wall subjected to horizontal loading is presented in this research article. The 3 storey vertically oriented coupled wall interconnected with coupling beams is modelled as solid elements in a finite element (FE) software named Abaqus CAE and the steel reinforcement is modelled as a wire element. For simulation of concrete models, a concrete damaged plasticity constitutive model is taken into consideration in this research. Moreover, with the help of concrete damage plasticity parameters, validation of two rectangular planar walls was executed with an error of less than 10 percent. Finally, these parameters are used for modeling and analyzing the static behavior of coupled walls connected with coupling beams. Furthermore, the maximum unidirectional horizontal loading helped in obtaining the compression and tensile damage as well as scalar stiffness degradation. Significantly, the research also found the plastic hinge location in the coupled wall as well as in the coupling beam, which are of utmost importance in nonlinear analysis. Doi: 10.28991/HIJ-2022-03-02-010 Full Text: PDF

Известной проблемой при проектировании подводных транспортных магистралей является прогноз русловых процессов на долгосрочную перспективу. Моделирование транспорта наносов и развития донных деформаций в руслах рек и окрестности гидротехнических сооружений как на физических, так и на численных моделях относится к одной из наиболее сложных и спорных областей гидравлики открытых потоков. Авторами предложено решение задачи долгосрочного прогноза развития русловых деформаций на участке реки Амур в районе расположения основной и резервной ниток подводного перехода магистрального трубопровода Восточная Сибирь - Тихий океан на основе математического моделирования задач гидродинамики и литодинамики в трехмерной постановке. Представлено описание используемой численной модели, учитывающей оползание подводных откосов, закрепленные (ремонтные) участки дна, взвешенные и влекомые наносы. Приводится информация о методике проведения калибровки и валидации численной модели на натурных данных. Обоснован выбор формулы расчета удельного транспорта влекомых наносов, которые имеют определяющее влияние на интенсивность и направленность развития русловых процессов. Приведены сведения, обосновывающие необходимое и достаточное количество слоев многослойной численной модели и размер расчетной ячейки. Расчетный алгоритм реализован на графическом акселераторе GPU, что позволяет за приемлемое время выполнять качественный прогноз деформаций русла на перспективу.

Forecast of river bed evolution for the long run is a well-known problem when designing underwater major transport arteries. Simulation of sediment transportation and ground strains development in river beds and vicinities of off-shore structures based on both physical and numerical models is referred to one of the most complicated and disputable areas of open-channel hydraulics. The authors offer a solution of the long-term forecast problem for riverbed strains in the Amur River reach in the area, where the main and standby lines of trunk line submerged crossing “Eastern Siberia - Pacific Ocean” are located, based on mathematical simulation of hydrodynamics and litho-dynamics problems in three-dimensional statement. Description of the used numerical model is presented; the model considers sliding of underwater slopes, fastened (repair) riverbed areas, suspended and bed load deposits. Information on the numerical model calibration and validation in full scale data is given. Selection of a formula for calculation of specific bed load sediments transportation, which have controlling influence on intensity and direction of river bed evolutions development, is justified. Information, which justifies necessary and sufficient quantity of layers of the multilayer numerical model and computational cell size, is given. The computational algorithm is realized on a graphical accelerator GPU, which permits to perform high-quality long-term forecast of river bed strains.

Se realizó un estudio del efecto de 3 sustitutos del cemento portland en la densidad relativa, la resistencia a la compresión y la absorción inicial (capilaridad), en blocks de concreto vibrocompactados. El cemento Portland es sustituido por tres diferentes constituyentes de la mezcla, en diferentes proporciones: a) 10% por ceniza volante, b) por 30% de cemento Impercem®, y c) el uso de un aditivo auto-curable. Los resultados indican que la ceniza volante, proporcionan un beneficio de resistencia a la compresión, sin embargo, los valores de absorción son inferiores a la norma. Adicionalmente, se realiza la caracterización de los materiales de partida por diferentes técnicas, Microscopia Electrónica de Barrido (MEB) y Difracción de Rayos X (DRX). Todas las medias físicas se efectúan en el marco de la normativa ONNCCE.
