Authors: Kumolosari Eli , Jalaali Bahrul , Suryopratomo Kutut , Dinaryanto Okto
Published: October 2020

The first geothermal binary system in Indonesia that has successfully implemented is a 500kW binary system in Lahendong. Yet, there is still a plenty room of improvement for binary system development in Lahendong. This study aims to give an alternative design of the binary system by using an organic Rankine cycle. The investigations of thermodynamic analysis based on the law of thermodynamics, silica scaling analysis, and optimization of working fluid selection are presented. Flashing process from separator produces vapor and liquid-brine with mass flow rates 48.6 kg/s and 173.6 kg/s at separator pressure of 10.23 bar. Based on second law thermodynamics analysis, obtained the maximum useful energy from brine flow is 7.2MW. Based on the simulation results, it is achieved that the potential power generated by waste heat from the Lahendong plant is 2.46MW with the net thermal and exergy efficiency by 11% and 34%, respectively. Compared to the current operating binary system, still, much available energy needs to be harnessed in the future from the Lahendong plant.

A fracture model in rats for the study of secondary bone healing was described. Standard open midshaft transverse metatarsal fracture was produced with bone cutting forceps in 28 rats. The commonly open and close fracture models utilized for bone and mineral researches are associated with varying degree of complications ranging from a high degree of fracture comminution to severe associated soft tissue injury which interferes with the healing process. We hypothesized that fracture model in rat third metatarsal bone could be associated with low -post-surgical complications and could be a reproducible model. To test this, open mid-shaft transverse fractures were created on the metatarsals of 28 rats. The objectives of the study were to evaluate the fracture complications, to determine the nature of fracture produced, evaluate the fracture consolidation during healing periods, and to assess the histological and radiographic healing of the fracture. The fracture produced in the mid metatarsal shaft of all rats was 100% transverse, 73% located at the midshaft. Minimal fracture angulations were recorded (0.48 ± 0.09o; 0.78 ± 0.17o) for anterior-posterior and lateral views respectively. Minimal soft tissue injury was recorded immediately post-surgery, but no infection and the delayed union was observed. Varying degrees of weight-bearing lameness was also recorded but seized at day six onward post-operative. Callus index observed was peaked at week 2 and 3 (2.02 ± 0.1, 1.99 ± 0.13) respectively but declined to 1.10 ± 0.04 at week 7 during the consolidation period. The fracture line disappeared completely at week 7. The histological and radiographic healing scores were (3.5 ± 0.13 and 3.75 ± 0.25) respectively (out of the maximum healing score of 4) at week 7 post-operative. There was a positive correlation between the histological and radiographic healing scores. The metatarsal fracture model is considered to be a suitable model for in vivo study of secondary fracture healing. Doi: 10.28991/SciMedJ-2020-0204-2 Full Text: PDF
WEAPONS OF ANCIENT EGYPT: THE MILITARY AND THE SACRED. PART 2
Authors:   Centre for Egyptological Studies, Russian Academy of Sciences, Reunov Yury S.
Published: October 2020

In the second part of the article development of Ancient Egyptian weapons in context of their combat use and ritual and magical understanding continues to be studied. The paper reveals the key aspects of origin and evolution of pole, small arms and throwing weapons. Attention is paid to identifying adoptions of separate technical solutions from other nations, which is mainly relevant to compound bows. Due to the fact that weapons served as a tool for not only solving practical problems, but also performing rites, some Egyptian religious beliefs are briefly discussed, namely those on the role of a pharaoh in maintaining the world order as well as on participation of gods in achieving victory. A system of features that allow attributing weapons as belonging to a utilitarian or ceremonial category is proposed.
ABOUT THE ATTRIBUTION OF ALKAMENES’ APHRODITE ἘΝ ΚΉΠΟΙΣ
Authors:   Lomonosov Moscow State University, Polezhaeva Kseniya O.
Published: October 2020

The article is dedicated to the statue of Alkamenes’ Aphrodite ἐν κήποις. The oeuvre is repeatedly mentioned in the ancient sources. The original of the sculpture has not reach the modern era. The connection of the work with the Roman copies causes an extensive discussion between art historians. Accordingly, the main purpose of this article is to identify a number of specific monuments with the statue of Aphrodite ἐν κήποις. To solve this problem, the author, first of all, carries out a detailed study and review of the messages of the ancient authors. Then, the author studies the historical aspects of creating the statue and some problems of iconography depicting the goddess Aphrodite in the art of the second half of the 5th century BC. The article highlights the main scholar works on both the work of the Alkamenes in general and the statue of Aphrodite ἐν κήποις in particular. The author compares the only original Alkamenes’ statue that has come down to us, the group of Prokne and Itys, with a number of the Roman copies that some scholars associate with the statue of Aphrodite ἐν κήποις. Such a comparison is carried out by applying a formal stylistic analysis. Together, the data collected and analyzed allow the author based on the collected and analyzed data argues that the type of leaning Aphrodite (or Aphrodite leaning against a pillar) is closest to the Alkamenes’ work.
ONTOLOGY OF EXHIBITION ACTIVITY
Authors:   Russian State University for the Humanities, Schtein Sergey Yu.
Published: October 2020

The article is devoted to theoretical modeling of the ontology of exhibition activity. The meaningful “frame” for expressing the desired ontology is the methodological presentation of activity. The method of schematization is used as the main tool for the formal expression of content. The methodological basis for theoretical modeling is the activity approach, the genetically constructive approach, the ontologization method and the constant method. In the construction special attention paid to the main variants of the source material of the exhibition activity and its product, as well as to the subject who perceives the exhibition in the conditions of its functioning. The resulting methodological construction can be used in theoretical studies of various aspects related to exhibition activity and in work that directly implies the implementation of the exhibition activity itself.
NEW SPAIN’S BAROQUE PAINTING: THE WORK OF CRISTÓBAL DE VILLALPANDO
Authors:   Saint Petersburg State University, Prikladova Mariia A.
Published: October 2020

The author of the paper investigates the work of Cristóbal de Villalpando (c.1649-1714). His paintings are analyzed in historical, cultural and social context. The author pays attention to the links and relationships between the art world of Europe and the Viceroyalty of New Spain. A significant part of his paintings belongs to the religious genre. Villalpando had been strongly influenced by works of Spanish and Flemish artists. Villalpando’s paintings demonstrate his penchant for narrative, monumentality and incorporation of many figures and details in his compositions. At the same time Villalpando acts as a distinctive painter, originally interpreting biblical scenes and signing himself as “inventor”. The relevance of the article is due to the lack of knowledge of the Baroque colonial artists’ heritage.
ILLUSTRATED POSTCARDS ON THE 1812 PATRIOTIC WAR: SPECIFIC ASPECTS OF THE NARRATIVE
Authors:   European University at Saint Petersburg, Mikhailova Natalia O.
Published: October 2020

The illustrated postcards of the early 20th century constructed a specific narrative about the 1812 Patriotic War. That narrative differed from both academic tradition and the war history translated by official institutions such as schools, churches, and local authorities during the anniversary celebrations in 1912. It is important to define this narrative, bearing in mind that the majority of people, who received such postcards lived in cities and were more involved in the entertaining activities, rather than educational context. Studying illustrated postcards in the context of other activities, which were conducted during the anniversary celebrations, such as publishing academic papers and brochures, organizing exhibitions, designing speeches for the anniversary celebrations allows us to identify a problematic approach to this material, traditionally considered to be a source for science.

Authors: Galvez Lucky Erap , Betty Rowena Alma , Nemenzo Fidel
Published: October 2020

In this paper, we establish a mass formula for Euclidean and Hermitian self-orthogonal codes over the finite ring Fq + uFq, where Fq is the finite field of order q and u2 = 0. We also establish a mass formula for Euclidean self-orthogonal codes over the finite ring Fq + uFq + u2Fq, with u3 = 0 and characteristic of Fq is odd. These mass formulas are used to give a classification of Euclidean and Hermitian self-orthogonal codes over F2 + uF2 and F3 + uF3 of small lengths.

Published: October 2020

Purpose: When the science lesson curriculum is examined, it is seen that the main purpose is to raise science literate individuals. In order to achieve this goal, constructivist approaches are needed instead of traditional teaching approaches. Predict Observe Explain (POE) is also one of the tools suitable for constructivism and includes a demonstration experiment and related prediction and observation steps.This study aims to investigate the effects of the Predict-Observe-Explain (POE) strategy on fourth grade students’ academic achievement, scientific process skills, and attitude towards scienceDesign & Methodology: In this semi-experimental research design, 17 students were in the control group and 15 were in the experimental group. For data collection, three different scales were used. The scales were administered to all participants at the beginning and at the end of the implementation. The experimental group was exposed to POE during their lessons for six weeks and the control group received regular instruction which is suggested by the Ministry of National Education. Findings: The results revealed that students in the experimental group had significantly higher scores than the students in the control group in terms of academic achievement and scientific process skills. However, no difference was observed in their attitude towards science. Implications & Suggestions: In subsequent studies, the effects of POE on different age groups can be analyzed.

MiTE: Program Penyunting Topologi Jaringan untuk Pembelajaran SDN
Authors: Fajar Sidiq Muhammad , Akbari Basuki  , Rosiyadi Didi
Published: October 2020

Software-defined networking (SDN) is a network programmability concept that separates the control plane from the data plane by proposing a centralized control plane called a controller. Thus, network administrators are able to program the entire networks and their components via the controller. However, learning SDN is challenging due to its complex network setup and the different types of SDN networks such as OpenFlow, and P4. To ease the learning curve, the use of network emulation and a graphical-based network editor is necessary. This paper discusses the implementation of such an application, called MiTE. It satisfies both requirements: a visual network editor enforced with a configuration generator for emulation purpose. We evaluate the program by implementing IP routing cases for both, OpenFlow-based and P4-based networks. The result shows that both cases can be created easily by using a mouse command. The program has more interactive user interface while the created topologies are more informative. Compared to similar applications, our proposed application has better support for a wider range of SDN networks (Openflow and P4), fine-grain network configuration, and a more informative user interface.
The 'Inter-Disciplined' Exhibition - A Case Study
Authors: Pleiger Henriette
Published: October 2020

This article contributes to the analysis and transparency of the practical processes of interdisciplinary exhibition-making. It identifies the academic discourse on interdisciplinarity as having the potential to provide a meaningful input to the formation of theory on temporary exhibition-making. The subject of enquiry is a recent case study from Germany. It investigates the relationships and decision-making processes that underpinned the production of the interdisciplinary exhibition Weather Report – About Weather Culture and Climate Science (Bundeskunsthalle, Bonn, 2017/18), which combined curatorial perspectives from the fields of art, cultural history and science. It traces the curatorial process, from forming an interdisciplinary team and negotiating conceptual ideas and methods, to object choices, interpretation and exhibition design. I argue that the complexity of interdisciplinary exhibition-making calls for a more precise and practice-oriented application of what is an often generalized notion of interdisciplinarity. By discerning between multi-, inter- and transdisciplinarity, and understanding the three terms as offering different qualities of interaction and integration, I suggest using these terms as a finer vocabulary for a detailed description and analysis of the practical processes of collaborative exhibition-making. Taking interdisciplinarity seriously also inevitably leads to the question of institutional consequences.
The Predicament of Representation in the Politics of Diversity: A Discussion Through Tate Encounters
Authors: Honorato Cayo
Published: October 2020

Considering the recognition by Arts Council England that cultural diversity within national museums and cultural organizations is ‘treading water’, the article proposes a typology of the criticisms available before putting forward the hypothesis that, no matter how legitimate those criticisms are, most of them are underpinned by an essentialist concept of representation. In order to test this hypothesis, it discusses Tate Encounters, a research project carried out at Tate Britain from 2007 to 2010, as a case study at the intersections of cultural policy and museology, visitor studies and audience engagement. The project provides a situated and multitextured account of the limitations restricting cultural diversity policy. However, it also demonstrates the difficulties in attempting to overcome those limitations – what I call ‘the predicament of representation’. Building upon a post-structuralist perspective, the article understands that, since we cannot escape from representing and being represented, a non-essentialist conception of representation has to be put into practice.
Who Is Leading the Project? A Comparative Study of Exhibition Production Practices at National Museums in Finland and the Baltic States
Authors: Reidla Jana
Published: October 2020

This paper presents research into exhibition-production practices at five national museums of four Baltic Sea region countries. The focus is the changes wrought by the expansion of exhibition teams, and how researchers in the curatorial role perceive their position, especially in relation to designers and project leaders. The analysis of semi-structured interviews with museum professionals showed exhibition production at museums comprise two models: A) curator-driven, and B) manager-driven. In Model A, the curator’s knowledge of museum collections is dominant. The curator creates the concept, and subsequently leads the exhibition project. The curator is the decision maker. In Model B, the field of communication is dominant. Managers are in charge of the design concept and fulfilling the exhibition. Managers are the decision makers. Curators feel their credibility as experts suffers and their competencies are underexploited, as they no longer have either authorship or leadership responsibilities.

Published: October 2020

As a key supporting equipment for the construction of LNG carriers, the installation platform undertakes the support and guarantee of LNG carrier tank internal construction. This paper takes the secondary shielding installation platform of A-type tank as the object of study, the study firstly considers the semi-rigidity of the nodes and the material nonlinearity based on finite element software, and then the residual structure is calculated using static nonlinear method after single truss, two trusses and three trusses are invalid  simultaneously. The research results show that the truss with higher components importance coefficient has greater impact on the residual structure when the truss is invalid; After the 2 trusses of installation platform become invalid completely, the further progressive collapse will not occur; When A1-HJ, A2-HJ and A2-HJ are dismantled at the same time, it will lead to the local progressive damage, which can cause the collapse of large-scale structures. The research findings can support the design and use of the installation platform.

This study investigated the financial performance of Bangladesh's State-Owned Commercial Banks, Islami Shariah Based Private commercial Banks and Conventional Private Commercial Banks over 12 years from 2006 to 2017. The objective of this study is to find out the financial performance of a bank based on CAMEL indicators. The finding of this study is that Islami Shariah Based Private commercial Banks and Conventional Private Commercial Banks has a good position than State-Owned Commercial Banks. Specific, Pubali Bank Limited, Standard Bank Limited, Prime Bank Limited, City Bank Limited and Al-Arafah Islami Bank Limited are in the best position in Bangladesh under this study. We also found that the performance of State-Owned Commercial Banks is not good. This study gives a policy implementation according to results. 1. State-Owned Commercial Banks should restructure the infrastructure. 2. It needs more emphasis on efficiency and effectiveness to control the cost and loan investment. 3. It will be required to pay more in insurance premiums. 4. It should be born in mine, for higher rating banks. We suggest to a higher number of rating banks that it’s hinders a bank's ability to expand by investing, consolidating, or adding more branches. We also suggest to all lower rating banks. The institutions with a poor rating will be required to pay more in insurance premiums.

Authors: Chen Zishen , Yu Jitao
Published: October 2020

The comparison results of three beach profile data repeatedly measured before and after the typhoon in Shuidong Bay, west Guangdong province which show that there are significant differences in beach profile erosion and response process. And the changes of beach profile can be divided into: strong downward overall low shoreline regressive type and overall slight erosion shoreline regressive type. Application of the modified mild-slope equation along three beach profile are simulated wave high reflection to the sea side, to the section vertical shore pressure gradient and including water roll force and radiation stress, the vertical shore forces one dimensional profile along the momentum conservation equation (radiation stress and water roll force) bottom friction and lateral mixing reaction between numerical solution, the momentum conservation equations of the wave increases the water flow velocity and section along the profile distribution of wave height and related forces. The analysis shows that the extent and difference of coastal erosion depend on the shoreline erosion mode stimulated by the maximum surge water of the coastal current and the maximum velocity of the coastal current and the dynamic state of the profile topography under the action of the profile location, morphology and incident wave elements.

Diversity and abundance of copepods occurring in Taninthayi coastal waters were studied and analyzed from the samples collected by R/V DR. FRIDTJOF NANSEN during the Myanmar ecosystem survey 2018. Seventy-nine copepods species belonging to calanoids (51 species), cyclopoids (21 species), and harpacticoids (7 species) were identified in the copepods community of Taninthayi coastal waters. Copepods species number and density were high at the nearshore stations (Sts 799, 842, 788) and low at the offshore stations (Sts 846, 802, 823). The resulted diversity index values of copepods were varied from 2.61 to 3.78 in species diversity index (H'), from 0.89 to 0.97 in the evenness index (E'), and from 2.51 to 7.50 in species richness index (D'). According to the correlation matrix, the abundance of copepods was positively correlated with temperature, chlorophyll a and fluorescence, and negatively correlated with salinity and oxygen.
NUMERICAL SIMULATION OF NATURAL CONVECTION FOR RAISED-CEILING ROOFTOP HEATED FROM BELOW
Authors: Kamiyo Ola
Published: October 2020

Attic design has a significant impact on buildings’ energy performance thus making investigation of its thermal performance characteristics imperative. Raised-ceiling is among the common complex attic configuration found in pitched-roof buildings. In this study, natural convection inside a raised-ceiling rooftop heated isothermally from the base wall (ceiling) is numerically investigated at a certain pitch angle range while keeping the enclosure base-length unchanged. The results show that the roof pitch and the kinks on the ceiling have a strong influence on the heat and fluid flow patterns. At low roof pitch, high heat transfer rate between the cold and hot walls leads to a multi-cellular flow structure. The number, size and strength of the counter-rotating cells change with the pitch angle. The kinks caused air velocity to double for every 15° increase in the roof pitch. The rate of convective heat transfer is enhanced with decreasing value of the aspect ratio.

Published: October 2020

In this paper, the elasto-hydrodynamic (EHD) performance of partial journal bearings has been studied. A numerical analysis has been conducted using the ANSYS Workbench (17.2) platform to investigate the performance of partial journal bearings. The lubricant used is considered Newtonian and incompressible fluid that flows steadily under laminar conditions, while the bearing material is assumed to be elastic, isotropic with smooth surface conditions. In the current FSI analysis, the lubricant flow has been predicted according to the finite_ volume method, while the finite element method has been adopted to compute the deformation and stress in the bearing surface. A wide range of operating and design conditions have been considered including the eccentricity ratio (0.1≤ε≤0.82), and arc bearing angle bearing (90ᵒ≤θ≤180ᵒ), while the values of bearing length to diameter ratio (L /D) and rotation speed (N) have been fixed at=0.77 and 1500r.p.m, respectively. The hydrodynamic pressure, performance characteristic of journal bearing, stress, and deformation have all been computed. It was found that the arc bearing angle and eccentricity ratio has a clear effect on the elasto-hydrodynamic properties of the partial bearings especially at high values of them.

Cannabis sativa is the most trafficked illicit substance in the world, 147 million people consume it recreationally. This plant contains more than 100 phytocannabinoids, the most important being 1-delta-9- tetrahydrocannabinol (THC). The genotoxic effect of cannabinoids has been proven in vitro and in vivo models, where damage to nuclear DNA and chromosomal aberrations (CA) was observed. This shows the clastogenic potential of this drug. In this research, we study genotoxic damage in Mexican individuals recreationally exposed to marijuana. The study of chromosomal aberrations was performed in 48 hour lymphocyte cultures of 30 exposed and 30 no exposed individuals. 100 metaphases were analyzed per sample. The type of CA was identified and counted. The number of CAs identified in the exposed group was 344 with a median of 9.5; the no exposed group had 218 CAs, with a median of 6.5. The statistical analysis showed a significant difference between both groups, p=0.013. Chromatid and chromosomal breaks were the most frequent aberrations. Comparing the exposure time vs. frequency of CA in the exposed group, we did not find a significant difference between sub-groups from 1 to 5 and 6 to 11 years. Similarly, in the analysis of the last exposure date vs CA, no significant differences were observed between the subgroups <1 week and >1 week. Our results show an increase in the frequency of the number of CAs in the individuals recreationally exposed. These results show evidence of the genotoxic potential of marijuana.
Comparison between sterilized zeolite and natural zeolite in the Cactus Pear (Opuntia Ficus-Indica L. Mill.) growing
Authors: Domenico Prisa
Published: October 2020

In this experiment it was determined whether the capacities of zeolites are influenced by the microbial colonies that are present in the soil, which can with their activity increase the interactions between roots, zeolites and soil. The microorganisms have the ability to lower the pH of the substrate and soil and can determine a solubilization of the mineral elements contained, which are more absorbed by plants. The experimental groups were: i) group without zeolites, irrigated with water and substrate previously fertilized; ii) group with natural chabazite and fertilised substrate; iii) group with sterilized chabazite and fertilised substrate. The zeolite was sterilized at high pressure saturated steam at 121 ° C for about 20 minutes. The theses treated with natural chabazite showed an improvement of all agronomic parameters analyzed on Opuntia ficus-indica plants, fruit characteristics and mineral content in the three cultivars Sulfarina, Sanguigna and Muscaredda. Natural chabazite gave better results than sterilized chabazite and untreated control, demonstrating that indeed the presence of the biotic component of zeolite plays a fundamental role in the interactions between zeolite and plant. All these aspects are very important for growers because the use of zeolites, especially natural chabazite, guarantees the possibility to reduce the amount of fertilizers in the substrates and to optimize irrigation while obtaining quality plants that grow better, produce more and suffer less.

Authors: Mohamd Salaheldin Abdelhamid
Published: November 2020

Purpose Better fixation of the mesh with better application to the posterior inguinal wall. Background: Stapling of the mesh is costly, that is why in Abdelhamid technique we are fixing it to outside, reducing the cost and port sizes without jeopardizing the outcome .Our technique can adjust the tension applied to the mesh with better justification of the size of the mesh. Patients: The study was conducted at Beni _ Suef university hospitals, between April 2018 and April 2020. Included in the study were 30 patients with unilateral primary inguinal hernia. Methods: A prospective trial was conducted modifying Abdelhamid technique for laparoscopic. TAPP inguinal hernia repair in which we fixed the mesh to the anterior abdominal wall using two prolene threads that passed to the exterior and were tied in place but the mesh was applied under the cord. Results: The operative time ranged from 40 to 60 min and follow up was for 12–16 months, during which time there was no hernia recurrence, nor TAPP pain. The procedure showed better application of the mesh on the posterior inguinal wall with reduced port sizes and was also associated with reduced cost. Conclusion: Direct application of the mesh to the posterior inguinal wall is associated with better fixation with completely abolishing the disparity in the size between the mesh and the posterior abdominal wall.

The aim of study was to evaluate the antimicrobial, cytotoxic and phytotoxic activities of the Oligomeris linifolia. The organic extracts were obtained by extraction the whole dried palnt with dichloromethane and methanol. The antibacterial activity was determined by inhibitory effect on the growth of Eschericha coli, Bacillus subtilis, Shigella flexinari, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi by using Agar tube diffusion method. The antifungal potential of the extracts was determined against growth of Candida albicans, Aspergillus flavus, Microsporum canis, Fusarium solani, Candida glabrata .Cytotoxic activity was evaluated by brine shrimp lethality test and phytotoxic activity was conducted against growth of Lemna minor frond. The phytochemical screening led to the presence of cardiotonic glycosides, anthraquinones and saponins in the plant. Methanol extract exhibited substantial antibacterial activity against Pseudomonas aeruginosa. In antifungal bioassay, Methanol extract showed 50% inhibition against Microsporum canis, while dichloromethane extract showed 40% inhibition against Aspergillus flavus and Fusarium solani as compared to standard drug. The dichloromethane extract showed significant activity at highest dose while the methanol extract showed good activity at highest dose against Lemna minor in phytotoxic bioassay. In Brine shrimp lethality bioassay methanol extract showed significant cytotoxicity at highest level of dose with LD50 462.40.The study concluded that Oligomeris linifolia has noteworthy antimicrobial, phytotoxic and cytotoxic potential.

Objective: To assess the effects of the legume (Pueraria phasoeloïdes) on the chemical parameters of the waste rock soils (saprolites) at the Agbaou gold mine, in the center-west of Côte d’Ivoire. Methodology and results: Soil samples were taken using the systematic sampling method at regular intervals of 20 m on the ramps and at 20 cm soil depth, using an auger during two consecutive sampling campaigns (2016-2017 and 2017-2018). The geometric coordinates of the sampling points were obtained using a GPS Garming CSX60 type. A total of 20 composite samples were made from 80 collected soil samples. Chemical analyzes were carried out on soil samples obtained. The results show that the contents of total organic carbon (TOC), total organic nitrogen (Nt), the C: N ratio and the pH values of the soils, under Pueraria phaseoloïdes legume were significantly improved between the ramps and between the two campaigns (p <0.05). Conversely, (CEC, exchangeable bases, (Ca2+, Mg2+ and K+) and phosphorus contents decreased significantly (p <0.001) between the ramps and the two campaigns. This reflects the improving effect of the legume on the chemical parameters of the soils. However, variations in trace element content between ramps and across campaigns did not show any significant improvement (p> 0.05).

Published: October 2020

The building shape is one of the most important considerations in the conceptual stage of building design. Since the building shape determines the size and the orientation of the exterior envelope exposed to the outdoor environment, it can affect building performance in many aspects: energy efficiency, cost and aesthetics. The shape and exterior structure of a house play major roles in determining its energy efficiency and the comfort of residents. The shape is comprised of the building’s height, width, and depth-also known as the footprint. The determination of the structural shape of a high-rise building would preferably involve only the selection and arrangement of the major structural element to resist most efficiently the various combinations of gravity and horizontal loading. Based on the above considerations, this study focuses on the responses by analysing the effects of the lateral loads on two 20 storied high rise structures having edge supported floor systems each of which one with square floor shape and another with circular floor and finally, presents a comparative result.
