Published: November 2021

Currently, various types of recyclable materials are used in civil engineering applications. One of the future challenges in the civil engineering field facing sustainability and the bulk utilization of waste materials without affecting the performance of the product related to the civil engineering field. Presence of bulk amounts of disposed and demolished materials including aggregates and undecomposed recycled polymers can be recycled. The main aim of reducing environmental impact and also reduction in the cost. Present research focusing on recycled polymers as partial replacement of bitumen in addition to recycled coarse aggregate in different percentages are investigated for its feasibility used in road construction. To achieve the objectives of the current research, 6 batches of bituminous samples were prepared and each case considered three samples for repeatability. The first batch is considered as a control sample without adding Recycled Coarse Aggregates (RCA) and recycled polymer. The second batch consists of 15% partial replacement of bitumen using polymer without recycled aggregate. Remaining batches 3 to 6 were 15% partial replacement of bitumen with polymer and partial replacement of coarse aggregates using recycled coarse aggregate say 25%, 50%, 75%, and 100%. Each batch was tested by reliable and standard tests in order to determine the most efficient mix (batch). The testing methods followed in this investigation are sieve analysis test, impact test, Los Angeles test, penetration test and marshal test. The results of sieve analysis test showed that the fineness modulus value for RCA equals to 4% with uniform graded graph. The specific gravity test results showed that RCA specific gravity is 2.61 which indicates that RCA is considered as coarse grained soils. Moreover, the Impact test for RCA equals 9.3%. In addition, the result for Los Angeles for RCA value is 19.07% and comparing it with the standard and it should be less than 30% is suitable for road construction. Furthermore, penetration test results of 15% partial replacement of bitumen using polymer showed that the average value equals 58 mm compared to 63.7 mm for bitumen without polymer. Finally, the result obtained from the Marshall Stability test showed that batch 5 partial replacement of bitumen 15% using polymer and the partially replaced normal coarse aggregate 75% with RCA gives better results in all aspects. A fruitful conclusion from this study is to follow the approach of utilization of recycled coarse aggregate along with recycled polymers in road construction.

Published: November 2021

There are growing concerns for neighbourhood lowliness in public housing development which affect residents’ wellbeing. Three major neighbourhood components that comprise the socio-economic characteristics of the residents, physical and social characteristics of neighbourhoods were identified and assessed for this study. A questionnaire survey was used to acquire primary data. Five, representing 16.7% of estates, were randomly selected from thirty public housing estates in the urban area of Ibadan. Subsequently, using systematic sampling technique, questionnaires were administered to 985 (20%) of households from the total of 4,922 households in the selected estates. Data collected were analysed using percentages, Relative Importance Indices and Multiple Regression Analyses. The results showed that 74.5% were homeowners, while renters, inheritors and government allotters had 22.7 and 2.8%, respectively. The results on the perception of physical characteristics indices (PCI) show that Alalubosa estate had the highest value with 4.23 PCI, while the social characteristics indices (SCI) revealed that Old Bodija estate had the highest value of 4.09 SCI. The results of regression analyses show that PCI and SCI were significant to residents' perception of neighbourhood quality where P-value < 0.00 probability level. The study conﬁrmed the linear relationship and level of signiﬁcance among the three factors. Doi: 10.28991/HEF-2020-01-03-03 Full Text: PDF

Authors: Tripathy Subodh Kumar 
Published: November 2021

Morphometric characters of fishes are measurable or metric characters. Morphometrics is a more or less interwoven set of large statistical procedures to analyze variability in the size and shape of organisms. Morphometrics and phylogenetics of a species are combined to utilize existing phylogeny which addresses hypotheses of shape change through evolutionary time. Morphometric differences among stocks of a species are recognized as important to evaluate population structure and form a basis to identify stocks. Advancements in morphometrics used powerful tools for testing and displaying differences in shape, isolated shape from size variation and identifying stocks of species with unique morphological characteristics enabling better management of the species. Traditional or standard morphometry has been improvised from time to time with advanced methods by technological advancements like geometric morphometrics, image analysis, principal component analysis, truss network analysis and multivariate analysis as well as many more to update knowledge and get more accurate information. These advanced methods have strengthened earlier technologies to improve upgrade fishery research throughout the globe. Doi: 10.28991/HEF-2020-01-03-05 Full Text: PDF

Authors: Sivakumar M. , Balasubramanian R. 
Published: November 2021

The present study aims to determine the second virial coefficient of gold over a wide range of temperatures from the boiling point to the critical point. A three - parameter modified Berthelot equation of state has been employed to determine the second virial coefficient of gold. The parameters of the equation of state are determined through the critical - point parameters of gold. The temperature -dependence of the second virial coefficient of gold has been investigated. The obtained results are compared with that of the van der Waals equation of state, Berthelot equation of state, Tsonopoulus correlation, and McGlashan correlation. The results of this work agree well with that of other correlations in the vicinity of the critical point. It is also established that gold obeys the single - parameter law of corresponding states. And, the new parameter introduced in the attractive term of the equation of state is found to be a thermodynamic similarity parameter. Doi: 10.28991/HEF-2020-01-04-02 Full Text: PDF

Authors: Montagna Sofia , Lo Duca Angelica , Marchetti Andrea 
Published: November 2021

Due to the arrival of COVID-19 in Italy and Europe, there has been a significant increase in deaths recorder in the year 2020, this increase is not justified by the number of deaths recorded for COVID-19. The hypothesis in that the deaths recorded for COVID-19 are underestimated. This study aims to estimate the possible number of unrecorded COVID-19 deaths using a predictive model built based on historical deaths recorded from 2015 to 2019. The estimate was calculated by comparing the number of deaths expected, according to the prediction for the year 2020 under normal conditions, with the deaths recorded during the pandemic in the same period which runs from March to September 2020. Through the comparison it was possible to obtain an estimate of the number of excess deaths which represent how much the arrival of the Coronavirus had affected the increase in death recorded. From the excess deaths, the number of COVID-19 deaths advertised and documented by official national sources was subtracted to obtain an estimate of the possible number of unrecorded COVID-19 deaths.

Authors: Alavi Somaieh , Peivandzani Shohreh , Mirmohammadsadeghi Seyedmehdi 
Published: November 2021

Successful implementation of Enterprise Resource Planning (ERP) system has many benefits for organizations, while its failure can have irreparable damages. Identifying the critical success and failure factors in implementing these systems seems essential. Therefore, evaluating the risk of implementing the organization’s resource planning before starting the project is necessary. Failure Modes and Effects Analysis (FMEA) should be assessed and analyzed. Then, for each risk, risk management strategies are mentioned and prioritized using the TOPSIS method. After categorizing the organization’s risks in four dimensions of stakeholders, growth and learning, process and finance and ranking them based on FMEA, it was determined that the stakeholder dimension is in the first place, which shows the effectiveness of this dimension in advancing ERP implementation. The second place is given to growth and learning, which can be concluded to what extent education and knowledge management can reveal its effect on the project. The third and fourth ranks are the dimensions of process and finance, respectively, which, although the concern of most organizations to implement ERP is the financial dimension, is in the last rank of the category.

The Beliefs of Local Communities towards the Conservation of Birds
Authors: Koki Jairus Nyongesa 
Published: November 2021

The community guides beliefs attached to different birds provides a practical index of the diversity and condition of an ecosystem on a site-by-site basis using birds as indicators. It is believed that protecting and managing such sites will result in the conservation of some of the most sensitive, fragile and ecologically rich habitats in the world. However, acceptance of the community guides beliefs concept and, thus, site conservation action, by local communities is dependent on their perception of the importance of birds with regard to some aspects of their livelihood. The study was undertaken to examine the community guides beliefs attached to different birds in Kenya within Maasai, Nyanza, Western, Rift Valley and Coastal regions. Results obtained from a google form questionnaire survey, suggest that the response with high proportion was from Western community or locality where people lived.

CITIZENSHIP AND COMMUNITY LIFE WITH REFERENCE TO THE CONCEPT OF DEMOCRACY AMONG STUDENTS WITH INTELLECTUAL DISABILITY: AN EXPERIMENTAL STUDY
Authors: Rose Asheena , Chandra Saumya 
Published: November 2021

Being a citizen of a country is the status of citizenship. If one has citizenship of a country, he would have the right to live there, work, vote, use community resources, pay taxes etc. Citizenship for persons with Intellectual Disability (PwID) is exactly the same as citizenship for anyone else. Citizenship is important for all of us. Having an ID is not a barrier to citizenship in fact it is useful because it helps communities come together, but it does become a barrier if society lets prejudice and power get in the way. The fundamental rights in our constitution are considered as basic human rights of all citizens, irrespective of their gender, caste, religion, disability etc. whereas when it comes to PwID, it sounds so difficult. Therefore, for this study 10 Adolescent students with Mild and moderate Intellectual disability were selected through purposive sampling method and a training program was organized to find out the understanding of these intangible concepts. Five selected topics i.e. community participation, community resources, fundamental rights, self-advocacy, election were included in the training program. The data collected was analyzed using both qualitative and quantitative methods both. The finding of the study reveals that through proper planning, role play, exposure in community and using visual clues, the awareness level of democracy, citizenship and election etc. can definitely enhance the understanding of citizenship among PwID.
A simple method for isolation of rest of trypsinized stem cells with magnetic beads
Authors: Bhatia Sudhir 
Published: November 2021

Till now, there is no laboratory in the world, which makes thoughts that there may be still stem cells remaining in the flasks after the trypsin treatment. The user checks the presence of stem cells during trypsinization with the microscope whether the whole population of stem cells has been collected. Magnetic beads are being used around the world to isolate different kinds of cells like CD4, CD8, CD34, and other cells. One of the advantages of magnetic isolation is that they can be used to isolate cells from solutions containing even a low number of targeted cells. We conducted the experiments to see whether all remaining MSC can be obtained from a trypsin-treated flask with magnetic beads isolation.
During the magnetic isolation with CD90 specific Magnetic beads, it was found under the microscope that there are huge numbers of cells being attached to beads. The results indicate that there are still a huge number of rest cells in the trypsinized flask but most of the users think that they have isolated all cells, which is not true and they are throwing away valuable stem cells. The magnetic beads can be used to isolate the rest of MSC because for many applications, there is a need of the largest number of stem cells for conducting studies like flow cytometry, molecular testing along with pre-clinical and clinical studies.
Application of Elastic Fastenings of Equipment to Increase Vibration Frequency of the Wagon Body
Authors: Guchinsky R. V. 
Published: November 2021

Improving dynamic performance is a priority when designing new rolling stock. The frequency of natural bending vibrations of the body is one of the most important standardised indicators, a preliminary assessment of which allows obtaining optimal body designs.The objective of the work is to assess the prospects for the use of elastic fastenings of equipment to increase the natural vibration frequency of wagon bodies of suburban electric trains. Calculations were based on the finite element method and block Lanczos method. It is shown that it is advisable to use the rigid area tool and linearly elastic finite elements to calculate the frequencies in the simulation. The main ranges of fastening stiffness are highlighted, where the effect of using elastic supports is different. It is proposed to determine the stiffness of fastenings according to a given vibration frequency of the equipment. When the equipment is rigidly attached, the relative mass of the equipment does not affect the body bending vibration frequency. With elastic fastening, a greater effect can be achieved with a larger relative weight of the equipment. The effect of using resilient mounts increases with heavier equipment located closer to the centre of the body.It is shown that the effect of shear admittance of fastenings on the body vibration frequency is within 1 % and may not be considered in the simulation. In the considered example of a wagon body of a suburban electric train, the use of elastic supports allows an increase in the frequency of oscillations of the body by 3–10 %.
Neutralization of Transport Documents in Road Transport
Authors: Poliak M. , Lakhmetkina N. Yu. 
Published: November 2021

In 1956 there was a significant step in international road freight transport – conclusion of Convention on the contract of carriage in international road freight transport (CMR Convention), the basic purpose of which was to unify the rules in the international transport of goods and thus promote the development of international trade. From a practical point of view, this was very important for both carriers and transporters. The Convention describes the most important document in the carriage of goods – the CMR consignment note.Recently, the term «neutralization» has been used in connection with the CMR consignment note, which is considered as an interference with the system of functioning of transport documents, which aims to obscure the actual movement of the consignment during transport. At the same time, neutralization of the consignment note is not so much contrary to legal norms as it can lead to undesirable consequences for carriers. For this reason, the question of whether it is possible to neutralize the CMR consignment note in accordance with the current rules and whether the neutralization of the CMR consignment note does not violate the functionality of the existing system is relevant. Therefore, the objective of this work is to study the reasons and methods for neutralizing CMR consignment notes, as well as options for handling neutralized consignment notes.Considering that neutralization of the consignment note has become a relatively common practice and means the exchange of original consignment notes or transport documents with other consignment notes or transport documents, canceling the actions of the first consignment note, in the article the authors, based on their own research, identified the possibilities of using the neutralization of the CMR consignment note in practice for certain types of goods, routes of the most frequent use, as well as the risks of these procedures in road transport.
The Project of Organizing Non-Stop Traffic at T-Intersections (Tyumen Case Study)
Authors: Pobedinsky A. A. 
Published: November 2021

The constant growth in the number of cars and trucks in single industry towns is forcing road design engineers to find ways convenient for all road users and pedestrians to move at intersections. Fulfilling such conditions is a difficult task but it can be solved, especially if there are many T-shaped intersections along the entire length of the road. Most often they are located along the line of railways, heating mains, river or lake banks, parks, etc. Since there are no adjacent roads, it is possible to ensure continuous movement of cars, but only in one direction.The objective of this work is to substantiate the project aimed at ensuring unhindered traffic at T-intersections of vehicles following 50 let VLKSM street in the city of Tyumen.To achieve this objective, the method of observation and recording, as well as the analysis of operation of optical devices that regulate passage of cars at intersections were used. With newly designed travel mode, there is no infringement of rights in relation to other motorists and pedestrians since the traffic light mode for the rest of segments keeps the same counting in seconds. A system of safe pedestrian crossing is envisaged along with an improvement in the environmental component of the whole city.For initial adaptation of motorists to new conditions, it is proposed to use a side green vertical arrow attached to the traffic light and signal columns that delimit traffic lanes for a «slow merge» into the flow of those leaving the secondary road. An undeniable advantage of this type of design is the minimum cost of reconstruction of intersections. Based on author’s own observations, it can be argued that this project increases traffic of vehicles moving from the central part of the city to the eastern part by 1,5–1,8 times.
