Authors: Al-Zuraiji Sahir M. , Basim O. Hasan  , Abdulwaheed Ola M.
Published: May 2024

The presence of heavy metal pollutants in refinery effluent significantly impacts the corrosion rate of carbon steel. The focus of this research is to analyze the impact of various inorganic pollutants, including copper, vanadium, nickel, and chromium ions, on the corrosion of carbon steel across different solutions. After conducting a thorough examination of various operating conditions, including pollutant concentration (ranging from 300-3000 ppm), temperature (30-60? C), and flow velocity (0-800 rpm). Our research shows that copper ions have the highest corrosion rate, with vanadium ions being a close second. Conversely, nickel and chromium had the most negligible impact on corrosion rate and, in some instances, even exhibited corrosion inhibition effects. It was also observed that an increase in flow velocity and temperature significantly amplified the corrosion rate of the metal ions investigated.

Published: May 2024

The improvement in solar chimneys' thermal performance and thermal behavior that can be achieved by adding metal foam has been tested in computational work. The flow and heat transfer governing equations for solar chimney models were solved using computational fluid dynamics (CFD). It was solved using the control volume numerical method in ANSYS FLUENT 14.5. It is used to construct a finite volume modeling technique for solving the governing equations and the radiation heat transfer equations. With standard flat absorber plates, the results showed that heat transmission was increased by the inclusion of metal foam (10 PPI), leading to an increase in air velocity at the solar chimney of around 13.3%. The highest average air velocity with 10 PPI drops by 54.4% as the height of the absorber plate changes from 5 cm to 25 cm respectively.

Published: May 2024

Abstract: This study aimed to determine which type of plastic – PET, HDPE, LDPE, PP, PS, and Others, produces most oil yield in terms of time of complete degradation, temperature and amount of plastics using a non-catalytic slow pyrolysis method; it also determined the physical characteristics of the oil yield in terms of its color and appearance; and it also aimed to determine which petroleum produced by different types of plastics are more efficient in terms of (a) production of oil and (b) combustion time. Production of oil and oil yield is presented in milliliters and percentage, respectively. Combustion time is expressed in seconds from the time of ignition to total disappearance of flame having 1ml of oil tested from each produced pyrolytic oil. Experimental-descriptive comparative method was used in determining the type of plastic that yields to most of pyrolytic oil. Based from gathered results, at constant temperature and amount of plastics, PS produced most petroleum at 29.5% oil yield followed by PP with 29%. While PET produced the least petroleum with 0.01% oil yield. Color varies at different types of plastics, given that PET and PP produces light brown color, LDPE produces light yellow while HDPE, PS and Others produces black color. PET, HDPE, PP, PS and Others produced liquefied petroleum while LDPE produces flammable wax product. PS produced most petroleum with 295ml (29.5%), and PET produced least oil with 1ml (0.01%). Combustion time varies at different types of plastics: PS at 145 seconds, PP at 141 seconds, HDPE at 115 seconds, Others at 78 seconds, LDPE at 77 seconds while PET produced non – flammable oil yield. Thus, PS is most efficient as an alternative fuel in terms of production and combustion time. For the betterment of similar study, future researchers are encouraged to test the pyrolytic oil yielded from different types of plastics in engine performance and machineries and the comparative performance to the available commercial fuels.

Published: May 2024

Amaranth is a plant that has calcium oxalate content in leaves. One of the roles calcium oxalate in plants is to increase drought tolerance. In addition, amaranth leaves also have anomocytic stomata. Stomata plant leaves are known to be formed genetically and not affected morphoanatomically under drought stress conditions, except density and conductance. Therefore, the research aimed to find out how the response of calcium oxalate levels and stomata of amaranth leaves (Amaranthus tricolor var. Red Giti) under drought stress. The research method used was a randomized block design (RBD) with two treatments, which are watering every day (WD) and watering at 50% wilting (SD) by observing stomatal density (stomata/mm2) and calcium oxalate content (%). Data were analyzed statistically with independent T-test and chi-square. The results showed that stomatal density and calcium oxalate content were affected by drought stress with a significantly decreased response. This indicates that the amaranth plant may become a plant that is resistant to drought stress by decreasing stomatal density and calcium oxalate levels.

Authors: Bin Md Syed Md Azalanshah , Wilson Tony
Published: May 2024

IPA is now a widely recognised qualitative approach within psychology. Drawing on its hermeneutic underwriting, enabled by hermeneutic philosophers (Aristotle, Heidegger, Gadamer, Ricoeur), this paper proposes eight Hermeneutic Themes ubiquitous within presentation of these philosophers’ writing. Research participant experiential narrative, accounts of understanding-in-practice, can be allocated structurally to these Hermeneutic Ubiquitous Themes (HUTs). For Gadamer, a hermeneutic consideration of practices was initiated by Aristotle’s early writing on phronesis or a situated understanding-in-practice. The present thematic analysis recognises such a Greek source. Exemplars of potential participants’ experiential narratives are provided within their respective HUTs prior to positioning Malaysian women viewers’ ethical ‘watching competencies’. Keywords: ethics, hermeneutic ubiquitous themes, Malaysia, phenomenolgy, phronesis

Published: May 2024

Wir fragen aus ärztlicher, philosophischer, ethischer und ökonomischer Sicht nach der Bestimmung der Stellung des Patientenwohls im Verhältnis zur Ökonomie und benennen mehrere Argumente, dass es zwischen evidenzbasierter Medizin und Mittelknappheit nicht um gleichgestellte Aspekte ärztlichen Handelns gehen kann, sondern unter anderem präzise zwischen Bedingung und Ursache unterscheiden werden muss. Darüber hinaus führen wir ein Beurteilungskriterium des Patientenwohls ein.

Published: May 2024

Problem. Large turnovers of export bulk cargoes in Ukrainian ports underline the necessity to improve cargo services provided by port operators. The first step of solving it is identifying the processes, the elements of cargo services and their formalization in time considering the case-and-effort relationships. Goal. To create a formalized description of the process and operations related to the maintenance of a contract consignment of export cargo in a sea port is in their mutual connection and mutual conditionality. Methodology. The tool of temporal logic was used to formalize the processes and operations of export bulk cargo servicing by stevedoring company (port operator) that helps to model the process within cause-and-effect relationships between components of the cargo servicing process. Results. The paper studies the main activity of the port operator at the operational level – the shipment for export of the contract cargo consignment. This process from the point of view of the port operator is presented as consisting of three components – the arrival of the contract consignment of cargo to the port; finding the consignment at the port; direct loading onto the vessel. For each of the named stages, the time points of its beginning and finishing are fixed, and the functions of the port operator are also defined. Each of the components is formalized in terms of temporal logic as a continuous process, and the finishing of one component is the beginning of the next stage, which ensures the interdependence of individual components of cargo shipment by the port operator. The receipt of the contract consignment of cargo (and, accordingly, all subsequent stages of its shipment) are not possible without a contract for cargo handling concluded with the port operator and confirmation of the possibility of acceptance the cargo. The stage of finding the contract consignment of port cargo is accompanied by the provision of additional services, which are provided by the port operator upon request and in accordance with the instructions of the cargo owner. The direct loading of the contracted consignment of cargo onto the vessel is actually the main type of production activity of the port operator at the operational level, the implementation of which is also accompanied by a certain set of additional related services. Originality. Cargo handling in ports is firstly presented as a formalized complex of interrelated processes in their logical sequence, starting from the moment of arrival of the contract consignment of export cargo at the port and finishing with its shipment to the sea vessel. Practical value. The obtained results can be used by port operators for the development of relevant technological schemes of cargo handling, in particular their digitalization, as well as monitoring of the process in consideration in order to identify "bottlenecks" and develop measures to eliminate them.
Assessment of the Impact of Intercity Bus Station Relocation on Passenger Flows in Urban Public Transport

Problem. The analysis of existing studies on transport hub operation in a city as well as on the methods for modelling the transport demand they generate showed that there are no specific recommendations for assessing the impact of the intercity bus station location on the trip patterns in urban transport system. This caused the need to search for a tool suitable to assess the influence of intercity bus station relocation on passenger service and passenger flows in the urban transport system. This paper shows the results of addressing this issue respective to urban public transport operation. Goal. The goal of the paper is to model the passenger flows to and from intercity bus stations considered transport anchors in urban public transport system as well as estimate the impact of station relocation on passenger flows and quality of service. Methodology. To achieve the stated goal, a survey of intercity passengers at the bus stations in the city of Rivne was made. This allowed for collecting the distances of the trips to and from existing bus stations and fitting the theoretical distribution to describe them. This distribution was used as the deterrence function during trip matrix calculation, which was required for the development of the public transport model. The model made it possible to quantify the potential impact of the Bus Station “Rivne” relocation on the urban transport system. Results. The considered bus station relocation can cause a decrease in the quality of service for passengers travelling to and from the station by public transport due to a probable significant increase in the average travel time and distance, the number of transfers, the passenger hours spent on travelling, and the passenger-kilometres covered to ensure the trips under study. Originality For the first time, the quantitative estimation of the impact of bus station relocation based on the regularities in the lengths of the trips to and from the stations was obtained. Practical value. The obtained trip length distribution can be used to calculate the origin-destination matrix, develop the public transport model, and quantify the probable consequences of the transport hub relocation.
Peculiarities of assessing bituminous binders adhe-sion to crushed stone

Published: May 2024

Problem. An important factor in ensuring the durability and reliable quality of asphalt pavements is a high level of adhesion of bituminous binders to the surface of aggregates. At present, three methods for determining the adhesion of bituminous binders are used in the road industry of Ukraine, of which the most common is the method for determining the adhesion to crushed stone according to DSTU 8787. Goal. The aim of the work is to determine the factors that affect the accuracy and reproducibility of the results of determining the adhesion of bitumen binders to crushed stone according to DSTU 8787 and to develop methods to improve the accuracy of the results. Methodology.To achieve this goal, we determined the adhesion of bitumen of different grades to particles of crushed stone of different sizes and mineralogical composition extracted from one deposit. Results. There are uncertainties in the methodology for determining the adhesion to crushed stone that significantly affect the accuracy of the results obtained. There are certain doubts about the criteria for selecting crushed stone particles for testing, the need to take into account their size and mineralogical composition. Based on the experimental data obtained, it was found that bitumen binder films of different thicknesses are formed on particles of stone material of different sizes, which, in turn, affects the results of adhesion – with an increase in the size of the crushed stone particle, i.e., with a decrease in the thickness of the bitumen film, a decrease in the adhesion values is observed. The second factor affecting the accuracy of determining the adhesion of crushed stone is the lack of requirements in the methodology for taking into account the mineralogical composition of the particles. Practical value. Based on the experimental data, it is recommended to introduce a number of additions to the text of DSTU 8787: it is advisable to select crushed stone particles for testing not by their size, but by weight, which will reduce the effect of the thickness of the bitumen film on the results obtained; selection of particles should be carried out in a wet state; for testing, it is necessary to select particles with an average mineralogical composition characteristic of the stone materials of the deposit. Taking into account the above provisions the accuracy of the results obtained will be improved.
Evaluating Intangible Cultural Heritage Policy of Balinese Handwoven Textiles
Authors: Parameswara Agung
Published: May 2024

Several key factors drive contemporary concerns about the sustainability of intangible cultural heritage. Cultural policy has given meaning and importance to the cultural diversity of society. However, the efforts to preserve intangible cultural heritage by providing a way to community welfare are facing new challenges. The article aims to present an analysis of local cultural policy from Bali Governance to sustain the intangible heritage of handwoven textiles by increasing the economy demand. Using a focus group approach, qualitative data were collected and using Nvivo12 to analyze the data from 15 interviews of weavers and practices of Balinese handwoven textiles living in Bali. This approach is used as a means to represent the complex diversity of opinions among members of the weaving group in a dynamic interaction that is provided so that a diversity of views emerges from the participants and direct clarification of the issues that influence the diversity of arguments on the reality of the impact on policy. The result found that the cultural policy is increasing the sense of identity by using Balinese handwoven textiles and significantly has the direct impact for the demand of handwoven textiles. Furthermore, the research revealed that cultural policy plays important role in shaping and reviving the traditional practices by evaluating the challenges of cultural industries such as industrialization, regeneration knowledge, environmental sustainability by reducing chemical dyes, the welfare of women weavers, market access and strong representation between communities.
