Published: June 2022

Air panas merupakan salah satu kebutuhan pokok bagi manusia untuk keperluan mandi dalam memperlancar metabolisme tubuh dan air panas juga mampu membunuh kuman penyakit. Di pedesaan air panas diperoleh dengan cara direbus menggunakan kayu bakar, tetapi pembakaran ini bisa beresiko terjadinya kebakaran. Begitu juga di perkotaan air panas diperoleh dari pemasangan water heater yang juga terbilang mahal karena membutuhkan daya listrik yang cukup besar. Untuk menghasilkan air panas yang ramah lingkungan dan gratis, penulis membuat perangkat solar termal sebagai sumber pemanas air rumah tangga dengan memanfaatkan energi matahari. Perangkat solar termal ini bertujuan untuk menghasilkan air panas agar bisa dimanfaatkan oleh masyarakat untuk keperluan rumah tangga. Dengan melakukan metode ekperimen atau pengambilan data secara langsung dari perangkat solar termal menggunakan thermocouple dari alat ukur VSCLAB WLN-01 BASE yang dipasang pada 5 titik setiap 60 detik sekali selama 5 jam 30 menit dari jam 10.30 pagi hingga jam 16.00 sore. Hasil temperatur air probe 5 yang didapatkan yaitu 43,5°C pada temperatur air di dalam tengki penyimpanan yang ada pipa spiral dan air panas ini akan digunakan oleh masyarakat dalam kebutuhan rumah tangga. Perangkat solar termal ini akan sangat menguntungkan bagi masyarakat karena untuk menghasilkan air panas tidak ribet lagi dan tidak mengeluarkan uang yang mahal lagi. Air panas dari perangkat solar termal ini juga tersedia secara gratis karena perangkat ini mampu menyimpan panas matahari selama 30 menit. Suhu air diharapkan dapat mencapai 60°C dilihat dari panas yang ditangkap oleh perangkat solar termal jika matahari bersinar lama menyinari perangkat solar termal.
Non-adherence to the residential private open space to building footprint coverage regulations in Lagos state: a research-evidenced need for introspection
Authors: Fadera Williams , Olaniyi Okedele
Published: June 2022

Residential private open spaces are instrumental to the creation of pleasant residential environments, contributing to the individual character, identity, and appearance of the residential area. Therefore, the problem of inadequate percentage of the residential private open spaces prevents the urban residential environment from attaining city sustainability. This problem is rooted in the non-adherence to building regulation standards especially in cities in Nigeria. In metropolitan Lagos, a study of three selected medium density residential estates reveals a non-adherence to the building regulation for the private open space to building footprint coverage ratios in the residential estates. The research method used in this study is methodological triangulation employing both quantitative and qualitative methods. The sampling is based on multistage cluster sampling, and the data collection tools were high resolution satellite imagery, survey (through the administration of questionnaires). The results of the study reveal that in the medium density residential estates, a typical spatial pattern of the residential private open spaces from imagery classification data and ground truth data have ratios that indicate 70% of the Residential lot is for building footprint coverage while 30% is reserved for private open space as opposed to the specification by the Lagos state building regulation which specifies that 60% should be reserved for building footprint coverage and 40% for private open space. In conclusion, it is imperative that there be an introspection and a possible review of the Lagos state building regulation in the face of 21st century realities of the Lagos metropolitan population demands.
Revitalization and landscape design of the park in Stari Mikanovci, Croatia; role of existing vegetation in generating new landscape solutions

Published: June 2022

In this paper, the procedures and indicators of systematic inventorisation and analysis of the existing vegetation of urban landscapes are presented and applied. The analysis of the vitality of existing trees was performed using the Visual Tree Assessment (VTA) method on the location of Park in Stari Mikanovci, Croatia. The results of these analyses were used as a basis for the protection and care of existing vegetation, but also their implementation in the design. For this purpose, four different conceptual solutions for the park design were formed. The process of generating different concepts tried to answer the questions: whether the maximum preservation of vegetation elements is a limiting factor in the creative phase of the design process, and whether consistent preservation of vegetation elements will generate similarities of design solutions. Four conceptual solutions were developed by four different authors who were given the same project task: (a) maximum possible preservation on the basis of analysis of the determined values of existing vegetation, and (b) uniform basic residential and recreational content of the park. All other components and features of the landscape are left as variable, arbitrary and author-determined parameters. Multi-criteria descriptive analysis of the proposed design solutions showed that the existing vegetation is not a limiting factor for the typology, diversity, disposition and degree of intervention in the creative phase of the design process.
Mythologizing urban project: case of Barona Street in Riga
Authors: Gutmane Helena
Published: June 2022

The paper attempts to deconstruct the production of the myth associated with a street renovation project in Riga’s historical centre. During and after the reconstruction of Barona Street, it was widely used as a public image of street renovation failure. Professional and civil society blamed ad hoc planning, wrong traffic organisation, inappropriate design, and poor construction quality. It is this association of solely spatial aspects with the failure to create qualitative public space that constitutes the core of the Barona Street Myth of Failed design. The article postulates that interaction of social identity and social emotions underline communicative landscapes when significant public spaces are being transformed and induce mythologizing of urban projects. Built on the analysis of the related reflections and criticism in media and public discussions, the thick description of the Barona Street project’s events attempts to show how socially and emotionally shaped perception of design and implementation process by involved social groups has contributed to the mythologising the renovation of Barona Street. The conclusions emphasize socio-psychological framing of urban analysis. The emotional implication of the Barona Street myth induces reattribution of the responsibility for Failed Design to individual political leaders, designers, and involved municipal workers, shifting public attention away from structural and governance inability to engage with public spaces and creating preconditions for involving urban project as a tool in political power games.
On a Couple-Stress Rivlin-Ericksen Ferromagnetic Fluid Heated from Below with Varying Gravity, Rotation, Magnetic Field and Suspended Particles Flowing Through a Porous Medium
Authors: Rahul  , Sharma Naveen
Published: June 2022

The thermal instability of a couple-stress Rivlin-Ericksen ferromagnetic fluid with varying gravity field, suspended particles, rotation and magnetic field flowing through a porous medium is investigated. The dispersion relation has been developed and solved analytically using the normal mode approach and linear stability theory. The effect of suspended particles, rotation, couple stress, permeability and magnetic field on the fluid layer has been investigated. For stationary conventions, it is found that suspended particles always have a destabilizing effect for λ>0 and a stabilizing effect for λ<0 and couple-stress, magnetic field and permeability of the medium have a stabilizing effect on the thermal instability under certain conditions. In the absence of the rotation couple-stress has a stabilizing effect if λ >0 and a destabilizing effect if λ<0. Rotation has a stabilizing effect if λ >0 and a destabilizing effect if λ<0. In the absence of rotation permeability has a stabilizing effect if λ<0 and a destabilizing effect if λ>0. Magnetisation always has a stabilizing effect (λ>0 or λ<0).
Spatial Sampling Design to Improve the Efficiency of the Estimation of the Critical Parameters of the SARS-CoV-2 Epidemic
Authors: Alleva Giorgio , Arbia Giuseppe , Falorsi Piero Demetrio , Nardelli Vincenzo , Zuliani Alberto
Published: June 2022

Given the urgent informational needs connected with the diffusion of infection with regard to the COVID-19 pandemic, in this article, we propose a sampling design for building a continuous-time surveillance system. Compared with other observational strategies, the proposed method has three important elements of strength and originality: (1) it aims to provide a snapshot of the phenomenon at a single moment in time, and it is designed to be a continuous survey that is repeated in several waves over time, taking different target variables during different stages of the development of the epidemic into account; (2) the statistical optimality properties of the proposed estimators are formally derived and tested with a Monte Carlo experiment; and (3) it is rapidly operational as this property is required by the emergency connected with the diffusion of the virus. The sampling design is thought to be designed with the diffusion of SAR-CoV-2 in Italy during the spring of 2020 in mind. However, it is very general, and we are confident that it can be easily extended to other geographical areas and to possible future epidemic outbreaks. Formal proofs and a Monte Carlo exercise highlight that the estimators are unbiased and have higher efficiency than the simple random sampling scheme.
Perspectives on Quality and Quality Assurance in the Management Consulting Sector

Management consultancy (MC) aims to generate value for organisations through enhanced organisational performance by providing objective advice and implementing business solutions (Management Consultancies Association (MCA), 2022). The success and growth of the industry, generating global revenues of US$634 billion and employing more than 4.3 billion people between 2018 – 2019 (Mosonyi, Empson and Gond, 2020), is a key indicator of the positive outcomes of management consultancy as a significant contributor to economies worldwide. However, the expansion and diversification of the unregulated sector poses issues for Quality Assurance (QA) as it seeks to ratify professionalism.
Insider Trading at Zagreb Stock Exchange
Authors: Kuveždić Marko , Dedi Lidija
Published: June 2022

This paper is the first paper that systematically observes and describes all publicly available data on insider trading on the Zagreb Stock Exchange during the period of June 2010 - June 2021. To accomplish this objective both parametric and non-parametric event-study tests are conducted using the data collected from 827 notifications published on the Zagreb Stock Exchange website. After filtering the notifications for overlapping events, there were 48 insiders’ purchase events and 50 insiders’ sales events. The results indicate that insiders can earn abnormal returns on share purchases based on their insider knowledge and that the information on insider purchases can bring additional information to outside investors. However, in the case of notifications of share sales by insiders, Cumulative Average Abnormal Returns (CAARs) after the event are not statistically significant and are just slightly positive, thus bringing no abnormal returns for insiders and not conveying information to the public. This suggests that the market may perceive sales having a lower informational content, as motivation for sales may be other needs, such as liquidity.
The Impact of Deferred Tax on Earnings Quality: Evidence from Algerian Companies
Authors: Kimouche Bilal
Published: June 2022

This paper aims to investigate the impact of deferred tax, as a technique adopted to support the economic orientation of financial statements over their legal form, on earnings quality as a required attribute to achieve the objective of financial reporting. The study used the model of Sloan (1996) through 280 firm-year observations that concern 40 Algerian companies from 2013 to 2019. Employing persistence and predictive ability as proxies for earnings quality, the results indicated that earnings of Algerian companies present a high level of persistence and a weak level of predictive ability. However, the deferred tax does impact neither the persistence of earnings nor their predictive ability. Therefore, accounting regulators in Algeria must simplify accounting for the deferred tax to encourage its application by companies and improve earnings quality.

Assessment of the impact of housing construction factors on rural development
Authors: Lugovskoy Sergey Ivanovich
Published: June 2022

The purpose of the study is a comprehensive analysis of the factors of housing construction affecting the development of rural areas, identifying their relationships, as well as the specifics of the implementation of the program of preferential rural mortgages in the regions and the damage of its impact on the village. The scientific novelty of the work carried out consists in confirming the hypothesis of the insignificance of the impact of the preferential rural mortgage program in the improvement of housing in remote rural areas and the acceleration of the process of deurbanization. As a result, using the example of the subjects of the Russian Federation and specifically the Stavropol Territory, it is demonstrated that factors of housing construction and home improvement affect the development of only large rural settlements located near administrative centers.

Philosophizing as a questioning about being
Authors: Burkhanov Rafael Ayratovich
Published: June 2022

The article is devoted to the study of philosophizing as questioning. It is substantiated that in terms of content, it is, firstly, an ideological questioning about the world and the place of human in it; secondly, conceptual questioning, which is realized in a developed philosophical theory; thirdly, metaphysical questioning, the purpose of which is the knowledge of being as such; fourth, transcending questioning, expanding and complicating the spheres of knowledge and practice; fifth, projective questioning aimed at creating and implementing possible models of a person; sixth, personal questioning, which forms the consciousness of a particular individual. Various types of philosophizing in ancient, medieval, modern European and modern thought are analyzed. It is emphasized that the definition of the main issue of philosophy as the question of the relationship of thinking to being, spirit to nature makes sense only within the framework of classical thought. In post-non-classical philosophy, interrogation is carried out within disparate semantic "clusters", through which it is impossible to comprehend the being as such, to cognize the world whole.
Navigating ‘Small Objects of Foreignness’
Authors: Rossiter Geraldine
Published: June 2022

Too often, totalizing discourses about the nature of the global metropole attempt to control its social and political story and render it an idealized object rather than a space of discrete subjects and perspectives. Walking the city is an act of social experience that allows the urban wanderer to see what has previously been hidden or inaccessible. Urban rambling reveals the ways in which racial and ethnic minorities have been colonized and marginalized, and how their communities have been rendered invisible as well. This paper examines how the metrolingual and metro-cultural practices of cosmopolitanism combined with the micro-strategies of decolonization serve to provide a counter-place to the dominant space of the Toronto city landscape. I frame this investigation with Dionne Brand’s novel, What We All Long For, as a narrative background, complemented by my own experience of aleatory urbanism through several Toronto neighbourhoods to explore the ways in which individual communities resist and re-negotiate the hegemony of settler-colonial municipal and linguistic practices.

Conductivity test is a test to physically measure the electrolyte leaking from seeds and be classified as vigor test. However, some factors may affect the result of the test; therefore, standardized procedures should be defined for its accuracy and consistency. The research reported here was aimed at obtaining specific method of conductivity test for wheat seeds and to study the correlation between conductivity test result with seed germination and field emergence. The experiments were conducted at the laboratory of BBPPMBTPH, Cimanggis, Depok from February to June 2013. The experiment was designed to identify the correct amount of wheat seeds and the volume of water used to soak the seeds. The experiment was assigned according to a completely randomized design (CRD) with 20 wheat seed lots and three replicates. Data collected including seed germination (SG), vigor index (IV) or First Count Test (FCT), field emergence (FE) at 8, 14, and 21 days, tetrazolium test (TZ), and conductivity test for nine combinations of wheat seed amount and the water volume for soaking (50, 75, and 100 seeds in 100, 150, and 200 mL of water). Results show that soaking 75 wheat seeds in 200 mL of water was best for conductivity test. This soaking condition resulted in negatively significant correlation between seed germination and field emergence. Moreover, low value of conductivity resulted in high values of SG, IV, FE, and TZ. Wheat seed germination and field emergence can be estimated using the equations of y = 0.028x2 – 3.321x + 104.9 and y = 0.022x2 – 2.704x + 87.96, respectively.

PSNR Improvement using Different Prediction Coding in Image Compression
Authors: Hasan Khamies K.
Published: June 2022

Differential Pulse Code Modulation (DPCM) is one of the predictive coding techniques. The number of previous pixels employed in the estimate operation is referred to as the order of the predictor. Predictor using one pixel for estimation is called “first order predictor”. A “second order predictor” utilizes two pixels and an “nth order predictor” would employ n previous pixels. From the results computed in this work, by testing the prediction mean square error (MSE) using different numbers of previous picture elements. The results show that the MSE decreases significantly by using up to three pixels, and further decreases of MSE are rather small by using more than three pixels that means the performance improvement becomes negligible and only a marginal gain beyond a third-order predictor can be achieved. That means, Peak Signal to Noise Ratio (PSNR) increases significantly by increasing the predictor order, the performance improvement becomes negligible beyond third order predictor.

Published: June 2022

Yoghurt production was modeled in this study based on different incubation temperatures, inoculum ratio of starter culture and incubation times. Experimental yoghurts were produced in two replicates and incubation final pH values of 343 yoghurt samples were determined. Resultant pH values were used in fuzzy logic modeling system. Fuzzy logic modelling was conducted in two sections: fuzzy rules were set and membership function was generated in the first section and defuzzification was conducted in the second section. Three different fuzzy sets (triangle membership function) were used for fuzzification of incubation temperature, inoculum ratio of culture and incubation time values. Since there were 7 membership functions of input parameters, 343 (7 x 7 x 7) rows of rule were generated. Mamdani method was used to tabulate fuzzy rules. Three trapezoidal sections of membership functions generated for defuzzification were used and membership function values were determined with the use of weighted average method. Incubation final pH values of 343 samples were assessed in modeling study and model outputs were compared with the expert decisions. Matlab (R2016b) software was used to assess model performance and model general performance was calculated as 90.27%. Automated yoghurt production lines should be designed in the future and put into service of food industry for present model to be used in industrial scale

Published: June 2022

Weighted automata can be seen as a natural generalization of finite state automata to more complex algebraic structures. The standard reasoning tasks for unweighted automata can also be generalized to the weighted setting. In this report we study the problems of intersection, complementation and inclusion for weighted automata on infinite trees and show that they are not harder than reasoning with unweighted automata. We also present explicit methods for solving these problems optimally.

The article presents the results of the use of fish fermented fodder paste, prepared from processing waste of Far Eastern commercial fish, in the diets of pigs during the growing period. The use of this additive had a positive effect on their meat productivity: slaughter weight increased by 4.5-14.4%, slaughter yield increased by 3.1-5.5%. The performed deboning of carcasses of experimental animals made it possible to establish the absolute and relative amount of the main tissues of their body. Studies have found that the carcasses of animals treated with the additive contained more muscle tissue by 9.39-28.12%, the meat index was higher by 0.16-0.74 units compared to meat samples from animals of the control group. The best indicators were noted when feeding fermented fish paste at a dose of 9.4%.

This work presents an investigation of three xanthone derivatives as the emitters for organic light-emitting diode applications. Through extensive photophysical and electrochemical studies, the thermally activated delayed fluorescence effect was observed and further applied in devices. Due to the substantial ΔEST gap, the final efficiency of the OLED was below 5%. The drop in the charge transfer energy was observed with electrochemical dimerisation of the donor molecule and increased molecule conjugation. The synthesised polymers exhibited an efficient thermally activated delayed fluorescence process through the shift of the singlet excited state energy level and decreased the ΔEST from 0.42 eV for the XNAP monomer material down to 0.12 eV for the polymerised derivative and final increase of the OLED device efficiency. Thus, the study presents the possibility of synthesising and tailoring many thermally activated delayed fluorescence emitters through electropolymerisation and applying this technique in working light-emitting devices.

Transimination reactions are highly effective dynamic covalent reactions to enable reprocessability in thermosets, as they can undergo exchange without the need for catalysts, by exposing the materials to external stimuli such as heat. In this work, a series of five biobased vanillin derived resin formulations consisting of vanillin acrylate with vanillin methacrylate functionalized Jeffamines® were synthesized, and 3D printed using digital light projection (DLP). The resulting thermosets produced, displayed a range of mechanical properties (Young’s modulus 2.05 – 332 MPa) which allow for an array of applications. The materials we obtained have self-healing abilities which were characterized by scratch healing tests. Additionally, dynamic transimination reactions enable these thermosets to be reprocessed when thermally treated above their glass transition temperatures under high pressures using a hot-press. Due to the simple synthetic procedures and the readily available commercial Jeffamines®, these materials will aid in promoting a shift to materials with predominantly biobased content and help drift away from polymers made from non-renewable resources.
Aqueous Speciation of Tetravalent Actinides in the Presences of Chloride and Nitrate Ligands
Authors: Bhattacharjee Rameswar , Miro Pere
Published: June 2022

Speciation of hexachloride tetravalent uranium, neptunium, and plutonium species in aqueous media have been investigated using density functional theory in the presence of inner sphere ligands such as chloride, nitrate, and solvent molecules. All possible structures with the formula [AnIV(Cl)x(H2O)y(NO3)z]4-x-z (An=U, Np, and Pu; x=0-6, y=0-8, and z=0-6) were considered to explore the speciation chemical space of each actinide. The nature of the mixed-ligand complexes present in solution is controlled by the concentration of free ligands in solution. A low chloride concentration is suitable to drive the speciation away from the highly thermodynamically stable hexachloride species. Furthermore, the formation of dimeric species can proceed through both olation and oxolation mechanisms. Oxolation is preferred for monomers that contain fewer water ligands, while olation becomes favorable for the complexes with more water ligands.

Noise pollution has not become a priority in environmental issues, but the potential negative impact on society based on studies can be in the form of physical and psychological disturbances, the main cause of noise in the urban area is transportation. Identification of noise sources needs should be done to ensure that the sound produced accordance with environmental characteristics. The Jagorawi toll road is the 3rd density toll road in the Jabodetabek area, compared to several other toll roads. Jagorawi toll road is bordered by residential areas. In the Cibubur-Cimanggis sector, this toll road is directly adjacent to residential areas with a distance of < 20 meters and some points do not have barriers to reduce noise. The Cibubur-Cimanggis sector is currently developing with the addition of the LRT, which will operate in 2022 so that current noise measurements can be used as baseline data at the study site. This noise monitoring is intended to conclude whether or not there is an effect of noise felt by the surrounding community from activities on the Jagorawi toll road and to obtain a reduction in noise levels using a single barrier with a height of 0.5, 1, 1.5 and 2 m. Noise monitoring is carried out using SNI 8421:2017 for 24 hours at 2 measurement points in residential areas. Point one and point two each have a noise value (Lsm) of 68.87 and 61.29 dBA with a correlation value of 0.605 (medium). The noise value has exceeded the quality standard for residential designation based on the Minister of Environment Decree No. 48 of 1996 (55 dBA), so a barrier is needed to reduce the noise received by the community. The analysis of the use of the barrier studied is a single barrier with G = 1. As the result of adding a barrier at point 1 with high 2 m, the noise value can be reduced by 16.7 dBA with a p-value of 0.00, so the addition of a barrier has a significant impact on the noise value. This study found the effect of noise from the Jagorawi toll road up to a distance of 114 m at a point that does not use a barrier, so the role of the barrier along the toll road is very important. With the use of a barrier, the distance required to reduce single noise originating from the toll road to < 55 dBA is 20 m.

During the Covid 19 pandemic, which required distance or online learning makes learning material difficult for students to understand, especially number material in junior high schools. One of the ways that teachers can use to facilitate students in learning is by taking approaches, one of which is the Realistic Mathematics Education (RME) approach. To support online learning where students can study independently with teacher guidance so that learning media is very important. One of the learning media developed is an interactive module based RME. The purpose of this research is to describe how the process of developing interactive modules based on realistic mathematics education on numbers and how the results of developing interactive modules are measured from the aspects of validity, practicality, and effectiveness as an alternative learning media. This study used research and development methods, the model used in this research was ADDIE (Analysis, Design, Development, Implementation, and Evaluation).
