Effect of prestressing force on flexural behavior of unbonded prestressed concrete beams strengthened by CFRP sheets
Authors: Tung Dang Dang , Tu Chu Van , Phung Huynh Thi Kim , Long Nguyen Minh
Published: April 2022

This paper presents an experimental study on the effect of prestressing force on the flexural behavior of unbonded prestressed concrete (UPC) strengthened by Carbon fiber reinforced polymer (CFRP) sheets. The testing program was carried out on nine large-scale UPC rectangular beams. The investigated parameters included the reduction of prestressing force (0%, 15%, and 30%) and the number of CFRP layers (0, 2, and 4 layers). Experimental results showed that the strengthening effectiveness of CFRP sheets, controlling cracking, and the energy absorption capacity tended to increase with the decrease of prestressing force and decrease with the increase of the CFRP sheets ratio. The effective performance of the CFRP sheets was shown by the increase in the strain of the CFRP sheets which was proportional to the decrease in the prestressing force. The CFRP sheets strongly interacted with tendons, significantly decreased the tendon strain, and delayed the point where nominal yield strain in tendons occurred; this reduction was significant when the prestressing force was small. Besides, the reduction in prestressing force considerably increased the displacement of beams and the additional strain of the tendons (up to 164%), but this increase became smaller as the number of CFRP layers increased.
Experimental investigation of the secondary creep of fiber reinforced concrete at high stress: Macroscopic measurement and digital image correlation
Authors: Tho Pham Duc , Tien Tran Manh , Thanh Dang Trung , Ngan Vu Minh , Ngoc Vu Minh , Sorelli Luca
Published: April 2022

The secondary creep of Fiber-Reinforced Concrete (FRC) under high sustained stress levels is a key issue for structural durability when considering the capacity to guarantee small crack widths under serviceability states. This study investigates the time-dependent deformation of FRC beams under loading level Ps/P0 greater than 80% (Ps is the load at reloading and P0 is the load before unloading) with various aggregate sizes by using both the classical macroscopic measurement and the digital image correlation analysis (DIC). Notched beams made of FRC and Fiber Reinforced Mortar (FRM) (i.e. without aggregate) were firstly pre-cracked by static load and then applied by a loading equal to 80% of strength. The evolution of the deflection, the crack width, and the crack propagation were both measured by traditional sensors and calculated by DIC. Comparison between results from FRC and FRM materials highlights the influence of microstructure heterogeneity on the secondary creep of FRC. Moreover, the DIC analysis helps to get insights on the secondary creep mechanism.
Study on the mechanism of urban planning information exchange to enhance the community participation in urban detailed planning in Vietnam – towards sustainable development
Authors: Hoa Ta Quynh
Published: April 2022

This paper explores the extent of the current mechanism to access urban spatial planning information of community in urban detailed planning projects (UDPPs), the constraints on urban planning information accessibility in Vietnam context to challenge the community participation for sustainable development. The research is based on an analysis of the planning information sharing content found in four UDPPs in Vietnam and interviews with 20 key informants. The research identified that the urban spatial planning information for the community is limited and difficult to access, and the planning information exchange process is one-way flow, authority-controlled and non-transparent. Besides, the lack of human resources and technological application provide a challenging context for involving the community in UDPPs. The paper concludes by proposing several recommendations for improving the urban planning information exchange process and technological tools that should be applied to foster community participation in Vietnam's urban context, towards sustainable development.

Authors: Cao Nguyen Thi , Nguyen Thi Hai Yen , Luu Hoang-Tung , Huynh Trong-Phuoc
Published: April 2022

The potential use of locally sourced ground granulated blast-furnace slag (GGBFS) and commercial sodium sulfate (Na2SO4) in the development of an eco-friendly sulfate-activated binder (SAB) was investigated in this study. The influence of Na2SO4 contents (1.5, 3.0, 4.5, 6.0, and 7.5% by mass of GGBFS) as a crucial sulfate activator on mechanical strength and durability performance of the SAB samples was evaluated through the tests of compressive strength, porosity, chloride ion penetration, and ultrasonic pulse velocity. The correlations among these properties were also established and discussed. The experimental results show that the Na2SO4 content had significant influences on both the strength and durability of the SAB samples. The porosity and chloride ion penetration were reduced as increasing the Na2SO4 content. Meanwhile, increasing the Na2SO4 content increased the compressive strength and ultrasonic pulse velocity of the SAB samples. Furthermore, the test results point out that using 7.5% Na2SO4 provided a significant improvement in the mechanical strength and durability performance of the newly developed SAB.
Buckling analysis of functionally graded sandwich plates resting on Pasternak foundation using a novel refined quasi-3D third-order shear deformation theory
Authors: Van Vu Tan , Hieu Nguyen Van
Published: April 2022

This study presents a numerical model for buckling analysis of the functionally graded sandwich plates (FGSP) laid on the elastic foundation through the Moving Kriging interpolation-based meshless method using a refined quasi-3D third-order shear deformation theory. The in-plane displacements encompassed a new third-order polynomial in terms of the thickness coordinate, will satisfy the natural vanishing of transverse shear stresses on the top and bottom surfaces. Furthermore, the displacement fields approximated by only four variables with accounting for the thickness stretching effect can lead to the reduction of computational time. Comparison investigations are studied to justify the accuracy of the present method. The influence of the aspect ratios, gradient index, and elastic foundation parameters on the normalized buckling load of FGSP is also studied and discussed.

Authors: Quang Tran Ngoc , Hue Nguyen Thi , Dat Mac Van , Duy Nguyen Van
Published: April 2022

Daily personal exposure to black carbon (BC) in different microenvironments in Hanoi, Vietnam was quantified for the first time. In this study, a portable instrument, microAethe® model AE51, was used to continuously measure BC concentrations in various microenvironments within buildings and transportation modes. Overall average daily personal exposure to BC from those microenvironments was 5.46 µg/h. The highest BC exposure was during commuting 13.48 µg/h and 5.74 µg/h for the motorcyclist and car driver, respectively. In building environments, the highest BC exposure was 3.98 µg/h in a coffee shop with smoking; the lowest BC exposure was 1.54 µg/h in a hospital department; while BC exposure in an office was 1.92 µg/h. The level of BC exposure in an apartment was strongly influenced by building ventilation modes. They were 3.58 µg/h and 2.15 µg/h with doors/windows open and closed, respectively. Our finding confirmed that commuting contributes disproportionately to the total BC exposure due to the high level of BC during traffic/travel. Building ventilation and air conditioning can significantly affect indoor BC levels and should be considered as a measure to reduce BC exposure within buildings in Hanoi.
Influence of artificial lightweight aggregate on property modification of unfired brick with low energy super-sulfated cement
Authors: Nguyen Hoang-Anh , Tran Vu-An
Published: April 2022

Rapid increase in concrete demand for infrastructural construction has been associated with depletion of natural resources, leading the urgent need to utilize manufactured materials substituting natural materials in concrete productions. This study proposes applying cold-bonded low calcium Class F fly ash (FFA) based artificial lightweight aggregate (ALWA) to partially replace natural fine aggregate in an ecological unfired brick with a low energy super-sulfated cement (SSC). To estimate the influence of ALWA on the brick properties, natural fine aggregate (FA) in the reference brick was substituted with ALWA at four different amounts of 25, 50, 75 and 100% by volume. Various properties including unit weight, flowability, dried density, compressive strength, water absorption, and drying shrinkage were investigated. Experimental results showed that ALWA addition as partial replacement of FA at all ratios resulted in the modified bricks with significantly increase in flowability and decreases in both unit weight and dried density. With neglecting minor reduction on compressive strength, the 75% ALWA substituting FA by volume was considered as the optimum value to manufacture the modified unfired bricks with remarkable enhanced performance.
Effect of pre-tensioned rope tensions on a ladder structure of turntable ladders
Authors: Nguyen Van Tinh
Published: April 2022

To expand the operating zone and control more precisely, it is vital to enhance the flexural stiffness of the ladder structures of turntable ladders. Based on one set of optimized 3-segment ladders, the author proposed a solution to increase the bending stiffness on each ladder while their mass hardly increases. Steel wire ropes are suggested to be added inside the handrails. They are pre-stretched and controlled to reduce the vertical displacement and rapidly quench oscillation at the ladder top. These benefits have been demonstrated in the dynamic aspect in other works. In this study, the effect of pre-tensioned rope tensions on ladder structure is investigated and evaluated according to current standards. The work includes modeling the ladder structure, defining loads, combining loads, investigating stresses and displacements according to the tension values. Afterward, the positive effects and negative influences, as well as the recommendations on tension load and tensile process, are presented. According to the obtained results, the structure still ensures the working conditions while the tension value reaches the maximum one. Most of the stress values in the structural elements decrease with increasing tension. The vertical displacement at the top decreases significantly.

Authors: Quang Nguyen Thanh , Cuong Tran Viet , Tan Nguyen Ngoc , Tan Nghiem Ha , Kawamoto Ken , Giang Nguyen Hoang
Published: April 2022

The paper presents experimental results and structural analysis of reinforced concrete (RC) columns made of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC) under concentric compressive load. The ratio of recycled aggregates in mixture (i.e, replacement ratio, r in %) was 0, 50, and 100% by mass, where r = 0% corresponding to NAC. The load and deformation curves including cracking load, ultimate load, crack width, and compressive strain of the tested columns, were analyzed to determine the effects of replacement ratio of recycled aggregate on the behaviors of square column structures. The results show that the increase of r reduced the load-carrying capacity of RC columns under the concentric compressive load. Horizontal and vertical cracks also were observed immediately for tested columns with high r. The effect of r of RAC on the mechanical behaviros, however, became relatively small and did not affect the behaviors of RAC columns, indicating that the RAC tested in this study was feasible for use in recycled concrete structures.

Phytocontent and Biological Effects of Olea europaea L. : A Review
Authors: Rashed Khaled
Published: April 2022

Olive tree (Olea europaea L., Oleaceae) leaves have been widely used in traditional herbal medicine to prevent and treat various diseases especially in Mediterranean countries. They contain several potentially bioactive com-pounds that may have hypoglycemic and hypolipidemic properties. Olea europaea is commonly known as Zaitoon. The ancient Egyptians, Greeks, Romans and other Mediterranean nations cultivated olives for its edible fruits and to obtain oil from them. Leaves of the tree became important when olive leaf extract was reported to be potent in reducing incidence of degenerative diseases, particularly coronary heart disease (CHD) and cancers of the breast, skin, and colon.  Olive leaves have the highest antioxidant power among the different parts of the olive tree. While in olive fruit, phenols (e.g.,TYR) and terpenoid hydrocarbon (Squalene) are the major components found in the oil. Much research has been carried out on the medical applications of olive. The choice of the plant was based on the good previous biological study of Olea europaea. Interest to choose this plant, may have been due to the widespread use of olive species medicinally, food industry and cosmetics.

Published: April 2022

Background and Aim: Multiple Sclerosis (MS) is among the most prevalent chronic and progressive neurological diseases with high simultaneity. MS is associated with some psychological conditions, such as depression and anxiety. Thus, we examined depression and anxiety in individuals with MS in this review study. Methods and Materials/Patients: We conducted this study using a systematic review method relying on the search from January 2010 to December 2020. Accordingly, we searched the following keywords: “multiple sclerosis, MS, psychiatric issues, psychological disorders, psychological problems, anxiety, mental health, quality of life, and depression” in 4 online databases (PsycNET, PubMed, Scopus, and Magiran). Ultimately, we selected 14 comprehensive papers that quantitatively and qualitatively examined psychiatric disorders in patients with MS. Results: A total of 14 studies were analyzed that included 27106 patients with MS. The results achieved by the analytical studies explained that depression and anxiety are significantly higher in patients with MS, compared with the healthy population. The prevalence of depression and anxiety in MS patients was reported to be heterogeneous. Conclusion: Data related to a large number of patients with MS presented a high prevalence of depression and anxiety in them; however, not separating the symptoms from the disorder can be misleading. Consequently, it is recommended to conduct further research to precisely assess the prevalence of depression and anxiety in these patients. It is required that future studies consider the further use of clinical interviews instead of self-reported questionnaires, using sample selection methods, and providing a complete report of patients' demographic, and clinical information.

Background and Aim: Neurovascular lesions can cause death or disability. Some of them are operable, but surgical approaches are complicated, and proper access to these lesions is crucial. A few of these surgeries occur during the residency educational program, and residents' experience in operating these lesions may be quite inadequate. Using new technologies like 3D-reconstruction of vascular lesion images may result in better training and improve residents' knowledge and understanding of these operations. Methods and Materials/Patients: Four senior neurosurgery residents were enrolled in this study. They were taught to use a 3D image rebuilding program (3D Slicer). They were then asked to rebuild a 3D image of every patient lesion, practice different surgical views, and review anatomical structures around the lesion before surgery. Results: All residents mentioned that their knowledge of surgical approaches improved, and they learned more from each operation. Two of them commented that more self-trust during surgeries led to more effective education. Their ability in surgical planning was enhanced too. Attending physicians of these residents believed that this practice improved the residents' skills and educational quality. Conclusion: New technologies can promote residency educational programs. It seems that working on 3D images of lesions before surgery can boost residents' educational attributes.

The article is aimed at ordering, in the first approximation, the subject field of the study, namely, structural alternatives for the reaction of Russian public authorities to the decision of foreign companies to withdraw their business from Russia. Approaches of the new institutional economics are used (especially in terms of comparative analysis of discrete structural alternatives), as well as elements of regulatory impact assessment to explain, first of all, the consequences of forced privatization and the introduction of external administration. The conclusion is made about the limited possibilities of Russian manufacturers in a number of industries to replace the products of foreign companies leaving the market, which is associated with insufficient implementation of the import substitution strategy. The necessity of a differentiated approach to the choice of a regulatory response is explained, including various models of market participants behavior.
Civilization split is back (On the book by V. L. Inozemtsev “Economy without dogmas: How the U.S. is creating a new economic order”)

The article discusses the key ideas of the new book by the respected Russian scholar Vladislav Inozemtsev “Economy without dogmas: How the United States creates a new economic order”. In this book, the author reveals the most important features of the modern financial system, which have become especially prominent during the COVID-19 pandemic. The overriding message of this book is the idea that in the coronavirus era the leading developed economies have finally moved into a new financial reality. According to Inozemtsev, its main characteristics include the following: surging money supply, public debt growth, and negative interest rates. Inozemtsev considers them to be indicators of profound changes in the structure of the Western economies which mark the inconsistency of statements about the imminent end of the Western hegemony in the global economy. We think that the most interesting point in the “Economy without dogmas” is the author’s attempt to link changes in the financial sector with technological and economic shifts. The debatable nature and abundance of original ideas contained in this book open up excellent opportunities for further discussion of urgent socio-economic issues.

Published: April 2022

The subject of the study in this paper is models and methods of optimization of the organization's project portfolio for the planning period, considering the effects of the previously made decisions. Project portfolio optimization is one of the responsible and complex tasks by company's top management solves. Based on the analysis of the known works in the field, the research purpose is described: to create a method that would allow solve the problem of multi-criteria project portfolio optimization for the planned period, considering the aftereffects of the previously made decisions. The research tasks are to enhance the method for solving the project portfolio optimization problem in terms of maximizing the difference between income and costs for all projects started during the planned period; to propose a method for solving the project portfolio optimization problem in terms of the social effects of projects that started during the planned period; create a method for solving the problem of project portfolio optimization for the planned period in a multi-criteria setting. There are the following results obtained in the paper. There is presents the mathematical model of the problem being solved, the problem objective functions include the difference between the receipt and expenditure of funds in time, the portfolio risks, and its implementation social effects. The mathematical model considers the provision of funds sufficiency for the implementation of projects in all periods, the required sequence of project implementation, and the mandatory inclusion of some projects in the portfolio for a given period. The problem under consideration belongs to the multi-criteria non-Markov dynamic discrete optimization problems. There is a proposed method for solving it in a multi-criteria formulation. The method is based on solving one criterion problem, and then a multi-criteria problem. The method is based on the minimax approach and implicit search.  There has been developed solving method for the problem of enterprise project portfolio optimization for the planned period following the profit criterion. In contrast to the existing methods, this method considers the constraints on debt absence and the aftereffects of the previously made decisions. The method served as the basis for creating risk and social effect optimization methods. A method for enterprise project portfolio optimization of the planned period is provided, which, unlike previous, considers the criteria of profit, risks, and social effect, the constraints on debt absence, and the aftereffect of the previously made decisions. That makes it possible to improve the quality of the generated portfolio.

Today, for intelligent computer systems of general and special purpose, the task of finding the optimal route is actual. Currently, there is a problem of lack of efficiency of methods for finding the quasi-optimal route. The object of the research is the process of solving optimization problems of finding a route. The subject of the research is a method for finding a quasi-optimal route based on metaheuristics. The current work increases the efficiency of searching for a quasi-optimal route using a metaheuristic method based on the ant algorithm. To achieve this goal, the work was created a method based on the ant algorithm and simulated annealing for the traveling salesman problem, was formulated the problem of the shortest path in the world of tiles, was developed a method based on the ant algorithm and simulated annealing for the problem of the shortest path in the world of tiles. Advantages of the proposed methods include the following. First, for calculating the probability of an ant moving from the current vertex to other vertices at the initial iterations, the random pheromone level plays the main role, which makes it possible to implement a random search, and at the final iterations, the normalized previous pheromone levelplays the main role, which makes it possible to implement directed search. This is ensured by the use of simulated annealing and increases the accuracy of finding a quasi-optimal route. Second, for calculating the change in the pheromone level at the initial iterations, the pheromone increment plays the main role, which ensures the breadth of the search, and at the final iterations, the previous pheromone level plays the main role, which ensures the convergence of the method. This is ensured by the use of simulated annealing and increases the accuracy of finding a quasi-optimal route. Third, the modification of the ant algorithm by calculating the length of the edges based on the Chebyshev distance, placing all ants in the initial vertex, checking for a dead-end, checking that the target vertex has been reached, and using Moore's neighborhood allows solving problems of the shortest path in the world of tiles. The performed numerical study made it possible to evaluate both methods (for the first method, the root-mean-square error was 0.04, and for the second method it was 0.03). The proposed methods make it possible to expand the area of application of metaheuristics based on the ant algorithm, which is confirmed by its adaptation for the specified optimization problems and contributes to an increase in the efficiency of intelligent computer systems for general and special purposes. The prospects for future research are the study of the proposed methods for a wide class of artificial intelligence problems.
