THE MANAGEMENT OF SPENT CATALYST IN RCC/FCC UNITS IN ASEAN REFINERIES
Authors: Nasution A.S. , Jasjfi E.
Published: February 2024

Catalytic cracking processes convert heavy feed- stock (heavy distillate, residue) into gasoline and light cycle stock for middle distillate components. Due to high impurity of feedstock and limited operating condition of catalyst regeneration, fresh catalyst must be added to replace a portion of spent catalyst continously, to maintain the activity of equilibrium catalyst in the reactor. Spent catalyst must be disposed properly so that it does not cause hazard or environmental concern. A survey was conducted on the management of spent catalyst in RCC/FCC unit in ASEAN refineries as an ASCOPE Technical Committee work programme for 1996. Indonesia was tasked as the Coordinator with the support of Member Countries. The Coordinator for each Member Country is listed in the Table 1. This paper discusses briefly catalytic cracking process, deactivation of cracking catalyst and the management of spent cata- lyst in RCC/FCC units
STUDY ON THE ENVIRONMENTAL ASPECTS OF PIT CLOSURE GUIDELINES FOR OIL AND GAS PRODUCTION ACTIVITIES
Authors: Mulyono M.
Published: February 2024

Exploration, development, and production activities associated with oil and gas production projects can have a variety of impacts on the environment. A variety of wastes are produced by such activities. Apart from the wastewater that is in the form of produced water, many kinds of solid wastes are produced during exploration and production of oil and gas. These solid wastes, among others, are drilling mud and cuttings, and tank bottom oily sludge. These solid wastes are dumped temporarily in a certain place called a pit before they can be treated further. In order to minimize and possibly eliminate the environmental impacts of those solid wastes, pit construction has to be developed in such a way that release of pit contents to the environment could be prevented. In addition, pollutant loading of ground water from waste leaks, releases of hydrocarbons and hydrogen sulphide to the atmosphere are some of the factors that have also to be considered. As dumping such solid wastes in a pit is a temporary storage, pit closure management has also to be developed. Explicitly, governmental regulation concerning with environmental aspects of pit closure has not been established yet. Nevertheless, environmental management approach of pit construction and closure could be established by referring to the available regulation, namely Governmental Regulation PP. 18/1999 juncto PP. 85/1999 - hazardous waste regulation, and the related Ministerial Decree, such as Bapedal Decree No. Kep.-04/BAPEDAL/09/19995 decsribing methods of landfilling or land disposal for hazardous wastes. This approach is based on the reason that such solid wastes are also categorized as hazardous wastes. In regard to pit construction, study on pit location should include the hydrogeology pattern of the site. Furthermore, pit wall materials are parameters that also have to be considered in minimizing impacts to the surrounding. Upon closing the pit, a pit closure plans that call for the dewatering of mud and reserve pit contents before burial have to be developed to reduce the chance of the downward transport of contaminants to shallow aquifers. The grading of soils covering the pits may reduce the chances of infiltration of rainwater, which may migrate to ground water. Other consideration, for example revegetation, has also to be included. All of the above factors should be considered in pit closure and assessment guideline. In addition to the available national references, other worldwide references such as those of US-EPA guidelines deserve to be considered in studying pit management. The author has conducted a short study concerning pit closure management that has been implemented in oil and gas producing companies. Goals of the study are to review the manual guideline or standard operating procedure (SOP) of pit closure applied to the fields. The followings are report concerning with the implementation of the study.
THE CONTRIBUTION OF PALYNOLOGY IN FIELD DEVELOPMENT
Authors: Lelono Eko Budi
Published: February 2024

The reliable interpretation of lateral reservoir distribution is required to gain high accuracy of reserve estimation in the oil field. Apparently, the geometry of reservoirs influences the volume of hydrocarbon. Widespread reservoirs are more preferred than isolated reservoirs because the former tend to store much larger volume of hydrocarbon than the later which usually produce limited volume of hydrocarbon. The lateral reservoir connectivity can be approached using various methods such as well log correlation, seismic correlation, biostratigraphic correlation, etc. In fact, each method sometime provides distinct result compared to that using another method. Therefore, the integration of those methods is actually needed to obtain reliable result. In the studied field, reservoir correlation was firstly constructed base on well log and seismic correlations. It was concluded that each reservoir could be traced along the studied wells. However, in order to cross check this conclusion it is applied palynological correlation as the studied sections are well recognized to represent deltaic sediment which yields rich palynomorph assemblage. It is now believed that palynology will be able to refine the correlation which was reconstructed base on well log and seismic. Data obtained during the analysis is considered to be confidential as this is provided for commercial work which is not public domain. Therefore, detail information of the studied wells cannot be revealed within this paper. The wells are named using numbers such as 1, 2 and 3, whilst reservoirs are labelled in alphabetical order, for example A, B and C. The studied wells were drilled in the oil field, so called Field "X" (Figure 1). Due to space limitation, only palynological data relevant to the correlation and sequence stratigraphic analysis of the studied wells (1, 2 and 3) are presented within this paper (Figures 3, 4 and 5). These data include the distribution of selected taxa, especially those which derived from marine, mangrove, back-mangrove, riparian, peatswamp and freshwater vegetations. Lithology is inferred from wireline logs which were provided by the client. These logs are shown together with pollen diagrams as seen in Figures 3, 4 and 5.
THE SHOREFACE - FAIRWEATHER WAVE BASE ENVIRONMENT OF THE MIDMIOCENE SANDSTONE IN THE CENTRAL PART OF THE MADURA ISLAND
Authors: Endharto MAC.
Published: February 2024

As mentioned in the previous paper (Endharto, 2005) this paper is part of the series of the depositional model of the Ngrayong Sandstone, which takes part especially in the central part of the Madura Island. This study also examines physical evidence of the best exposure of the study area. The central part is located between 07 01' 18" S - 113 32' 56" E and 07 04' 55" S- 113 36' 54" E, covering the area of Tanjung - Pasean to the north and Mentok - Kertengeneh - Sentol to the south. (Figure 1). The Geological work was carried out during June - July 2005, where the particular attention was concentrated within the central region of the island. There are 3 major key outcrop areas were studied and assigned for the depositional setting of this area (i.e., Tanjung toward Pasean River, Mentok - Kertengeneh Oil Field and Sentol Daya sections). This worked has attempted to sort it out both vertical and horizontal sections with applying the stratigraphic measuring sections (outcrop/surface logs), horizontal distance using passing compass, supported by petrography and paleontology analysis, and trying to look at the internal sedimentological structures to get into broadly image of the depositional system within this area.
POSSIBILITY TO ESTIMATE BULK PERMEABILITY FROM SEISMIC DATA
Authors: Munadi Suprajitno
Published: February 2024

Permeability is one of the most important reservoir parameter which determines the reserves. Unlike the porosity which is considered to be the static property of oil and gas reservoir, permeability is the dynamic property. It reflects the ability of reservoir rock to transmit fluid (oil gas or water). The reservoir rock is located deep below the subsurface, so that the measurement of the permeability is usually carried out from the cores. So far there is no well logging tool which measures the rock permeability directly. Physically, there is no direct relationship between porosity and permeability, the estimation of permeability from the cross-plot between porosity and permeability is just a rough estimate, but it is usually accepted in practical application. Apart from cross- correlation method, there is now exist a sophisticated approach to estimate permeability based on well log data using artificial neural network. There now exist a method which is widely accepted to estimate the porosity of the subsurface layer using seismic method. This method exploits the relationship between porosity and acoustic impedance of the sub- surface layer. And since acoustic impedance can be derived from the seismic amplitudes, it means that the rock porosity can be estimated from seismic data. A new question can be exposed as follows : "Is there any seismic wave parameter or quantity which is theoretically can be releted to permability ?" (so that the estimation of reservoir permeability can be estimated from seimic data). This paper tries to propose an idea to use a specific seismic wave parameter whis is theoretically can be related to the permeability of a reservoir rock, with a hope that more detail research can be pointed to that direction. This idea is supported by qualitative analysis and some theoretical findings
ESTIMATION OF WATER SATURATION IN CARBONATE RESERVOIRS WITHOUT RESISTIVITY LOG DATA. PART I: THEORY AND EXISTING MODEL
Authors: Widarsono Bambang , Atmoko Heru , Ridwan Ridwan , Kosasih Kosasih
Published: February 2024

This paper presents an observation over a suggested approach for establishing water saturation model that is specifically designed without the need of resistivity log data. One of the main strength of the approach is that the resulting water saturation model can be specifically established for local or specific use only. This is true since the approach can be applied using carbonate rocks that are obtained locally or from specific areas. Another important conclusion is that this approach can also be applied for any carbonate rock classification as long as the classification can clearly group carbonate rocks into groups with distinctive petrophysical properties. This paper – first part of two – presents theory and rock classification that underlines the approach, as well as procedure and the existing models available.
PLEISTOCENE PALYNOLOGY OF THE WAIPONA BASIN, PAPUA
Authors: Lelono Eko Budi
Published: February 2024

The Pleistocene sediment from a single well drilled on the back bone of Papua provides good pollen recovery which shows the mixture of the Australian and Asian elements. The well drilled the sediment more than 3000 meter deep which is mostly assigned to Pleistocene age. Only small part of the basal section belongs to Pliocene age. In order to obtain accurate interpretation, the age interpretation is also defined using other disciplines including foraminifera and nannoplankton. The Australian affinity appears as an origin since this island has derived from the Australian continent. On the other hand, the existence of Asian palynomorphs within the studied sediment indicates the dispersal of Asian flora into East Indonesia following the arrival of the Australian plates at about the end of Oligocene. The Asian taxa then migrated to the land mass of New Guinea which rose above sea level from about Middle Miocene onward. In the studied section, shallow marine sediment in the upper interval contains sufficient palynological assemblages which clearly indicate climatic changes from dry or seasonal to wet climate as reflected on the changes of the proportion of dry/ seasonal and wet climate indicators. Unfortunately, due to low pollen recovery, the climate condition of the lower interval can be hardly interpreted. This could have happened because the sediment of the lower interval was deposited in deep marine environment, which was situated far away from the pollen sources in the continent.

Published: February 2024

Since 1980 the number of Indonesian Sedimentary Basin which is officially announced by the government are 60 basins, but informally the variation in the range of less than 60 up to around 66 basins. Based on stratigraphic and tectonics conditions of some areas there are overlapping layers between Tertiary Sedimentary and Pre Tertiary Basin. In general the definition of a sedimentary basin is a region, part of the earth's crust where sedimentary strata have been deposited in a relatively much greater thickness than its surrounding area. The nomenclature for basin is referred more to basinal areas. Based on sedimentary basin classification there are: type of plate where basin exists, basin position in the plate margin, type of plate interaction, time development of basin and basins fill with respect to tectonic and shape of the basin. The updating classification using new technology and knowledge of the basin, can also update previous knowledge because of the limitation of the data and the lack of new concept when the report was published. 63 Tertiary Sedimentary Basins (16 producing basin of oil and gas, 8 drilled basin with discovery, 15 drilled basin with has no discovery yet and 24 basin which has not been drilled yet) could be used as a basic data for development of science and technology, to support government policy and investor, to improve and accelerate oil and gas exploration and production in Indonesia.

Published: February 2024

Naturally fractured reservoir differs from clastic reservoirs in the sense that the concepts of porous media which were usually applied for clastic reservoir analysis must be modified. This means that handling naturally fractured reservoir is also different compared to handling clastic reservoir. The porosity may be changed a bit bigger but the permeability is drastically changed. Also at a depth where rock layers are usually tight, naturally fractured reservoirs converts it to become a good reservoirs. Naturally fractured reservoirs can be found in some part of the Indonesian basin which may contribute a considerable additional reserves in the near future.

CHANGING WELLBORE STORAGE IN GAS WELL TESTING
Authors: Tobing Edward ML.
Published: February 2024

Extended wellbore storage can be mistakenly interpreted as a reservoir response in gas well testing with surface shut in. This interpretation usually results in false value for permeability, skin and reservoir size and shape. This paper investigates changing wellbore storage in pressure transient testing with surface shut-in in gas well. This study was prompted by the observation, that in gas wells, many of the buildup tests obtained with surface shut-in exhibited complex reservoir model behavior with relatively low skin. The results presented in this paper are based on well test simulation and field data from North Sumatera. This work demonstrates the effect changing wellbore storage on the pressure derivative curve. Knowledge of the expected pressure derivative shape, and duration, will improve the design of buildup tests that will allow enough time for the actual reservoir response to be observed. This will result in a reliable reservoir model and correct estimation of permeability and skin factor.
A SINGLE PHASE MODEL FOR ANALYZING GAS PIPELINE NETWORKS
Authors: Tobing Edward ML.
Published: February 2024

A single phase flow model has been developed for gas distribution pipeline networks. The model is developed based on looped-system approach with some modifications. In this model, a equation of state model is implemented for predicting the gas properties required for the governing equations of the network system. By utilizing the Linear Theory Method, the Panhandle’s single phase gas flow model is implemented in this model to predict the hydrodynamic variables in each leg of the network using the iterative technique which is developed in this study. A generalization of the single phase network model is provided thereby making it possible for the single flow model used to be replaced by another one that may be more applicable for a particular situation. Using the iterative procedure developed, pressure at all nodes, gas flow rate at each leg can be predicted. The test results demonstrate that the model can serve as a predictive and design tool for solving a single phase gas flow problem in pipeline network.

Published: February 2024

Biodiesel is a renewable source of energy which is expected to play a signifi cant role for reducing andreplacing the existing non-renewable fossil fuels. Palm oil is one source of biodiesel feed stock which hasbeen used for many years and gave so many advantages such as high oil yield, cheap to produce and torefi ne, has similar characteristics with petroleum-derived diesel, and has lower emission. However, someissues, such as food stock security, land use changes, and biodiversity extinction, have arisen which needto be considered and solved wisely. Life cycle assessment (LCA) study shows a positive net energy and anet positive sequestration on GHG emission (up to some level of conversion from palm oil to biodiesel)which means biodiesel from palm oil has a high potential to replace fossil fuel and also an environmentalfriendly fuel.

Authors: Iskandar Utomo Pratama
Published: February 2024

Coal seams are an alternative storage options besides depleted oil and gas reservoirs and deep salineformations. They are suitable to different degrees for CO2 geological storage as a result of various intrinsicand extrinsic. The potential use of this geological media requires suitability assessment and the amountof CO2 can be stored. This paper presents the fi rst attempt to evaluate the characteristics of coal seams inRambutan Field, South Sumatera, in terms of their suitability for CO2 storage and the potential storagecapacity. A set of 5 semi-qualitative criteria has been developed for the assessment of 4 seams that includespermeability, coal geometry, structure, homogeneity and depth. CO2 adsorption capacity estimates werederived from laboratory experiment by employing Isothermal Langmuir. The results show the 4 seams ingeneral are suitable for CO2 storage. The adsorption capacity from seam 2, 3, 5 and P are 22.18, 25.09,24.53, and 34.12 m3/t dry-ash-free basis respectively. The highest CO2 storage capacity can be stored atseam P enabling the CO2 in dense phase (supercritical).

Published: February 2024

Carbonate rocks are highly heterogeneous. That which leads to rock typing of carbonate rocks is noteasy to do even by integrating static and dynamic properties of rocks. In accordance with the defi nition ofrock types that are commonly used, rocks or parts of rocks that have been deposited in the same environmentand experienced similar diagenetic process have similar physical characteristics, such as grain orrock fabric texture, pore geometry and structure pores, then the characters that will be used as the basisfor determining rock types. The use of rock fabric has been performed by many previous researchers. Whilethe use of attributes in the rock pores typing is still limited and more emphasis on engineering purposes.The objective of this study is to integrate all three of these characteristics in the determination ofrock typing. Theories that have been established and related to fl uid fl ow in capillaries and porousmedia that will be used to characterize the pore geometry and pore structure. Furthermore, thecharacteristics of the geological evidence will be conducted using core description, petrographyand other data to obtain the relationship between aspects engineering and aspects geology inaccordance with concept or defi nition of rock type in question. In rock typing, permeability and porosity characterize the pore geometry and pore structure. This study proves that there is a strongrelationship between the characteristics of the detail geological and architecture pores. Thus,the resulting methodologies rock typing can be universal with respect to aspects of geology andpetroleum engineering.

A detailed combined geological and geophysical study in North Sumatra basin has shown thatprospective formations for shale play containing gas sweet spots are found to be in shales from Bampo,Belumai, and Baong Formations. Bampo Formation exhibits low shale gas potential with very low tomedium in organic material contents, maturity index of immature to mature, and moderate brittleness. Rockswithin the formation tend to be reactive to highly reactive to water, with a moderate degree of swellingcapacity. Porosity varies within 5.8 - 7.4 % with permeability ranging from 0.37 to 3.2 mD. Sweet spots inthe formation found around Basilam-1 and Securai-1wells occupy about 21% of the formation. On the otherhand, Belumai Formation shows moderate to good shale gas potential, with low to high organic materialcontents, immature to mature levels of maturity, and moderately brittle to brittle. Sweet spot areas in theformation found around the two wells are about 29% of the formation. For Baong Formation, analysisreveals moderate to good shale gas potential, with low to medium contents of organic material, immatureto mature in maturity index, moderately brittle to brittle in brittleness, and tendency of being reactiveto highly reactive to water but with low degree of swelling capacity. Sweet spots in the formation foundaround the two wells occupies are roughly 11% of the total formation volume in the area. Basin modelingleading to gas resources estimation for Baong, Belumai and Bampo Formations has led to estimatedvolumes of 6,379 TCF, 16,994 TCF, and 25,024 TCF, respectively, with a total amount of 48,397 TCF.The resources figures are speculative in nature and do not incorporate any certainty and efficiency factors.
The effect of metal sulfides on hole and electron transport buffer layers in organic photovoltaics: experimental and numerical device simulation investigations.
Authors:   , Adedeji Michael Adepelumi
Published: February 2024

Organic solar cells (OSCs) are promising alternative renewable energy sources that often suffer from insufficient absorption of solar radiation, short exciton lifetimes and small diffusion length of their charge carriers. Several strategies are being investigated to overcome these challenges in a move towards the commercialization of this solar cell technology. Increasing the path-length of incident electromagnetic radiation within the photo-absorbing layer of the solar cell, may elongate the time that light spends within the solar cell, thereby increasing the light-matter interaction time and consequently the photo-absorption within the photo-active material of the solar cell. The process described may be accomplished if suitable plasmonic metal nano-structures are added into the solar cell matrix. This intervention may also enhance the collection of the photo-generated charge carriers. The effects of metal sulphide nanoparticles incorporation in organic solar cells were studied and presented in this thesis. The metal sulphide nanoparticles were characterized and introduced into the hole- and electron- transport layers of fullerene and non-fullerene electron acceptors based solar cells, to elicit improved photoabsorption via the localized surface plasmon effects and facilitate better charge collection at the electrodes. Devices were fabricated both in an ambient environment and in a controlled environment (Nitrogen filled glovebox). The metal sulphide nanoparticles were incorporated in the fabricated solar devices using both the conventional and inverted device architectures. The power conversion efficiencies of the devices improved significantly after the incorporation of these nanoparticles. Device numerical simulation studies were also performed to reproduce some of the experimental results with a view to further investigating the devices and discussing their charge transport characteristics. The simulation results show improved charge carrier characteristics from the metal-sulphide doped devices by way of improved conductivity and shifted Fermi level offsets which were aided by the presence of the metal-sulphides. Asides from successfully achieving improved device performances in the investigations and simulations carried out in this thesis, this thesis successfully demonstrated the incorporation of nano-composites in non-fullerene acceptors-based organic solar cells for the first time to the best of our knowledge.

Published: February 2024

A critical analysis of the South African identity in South African animation, focusing on the representation of a South African identity within the animation. The study looks at contemporary South African animations, both, television series and feature films examining the visual language, narratives, themes, and use of language within the animations as well as the key developments within South African animation. The majority of the inquiry is seen through a qualitative collective case study approach looking primarily at the analysis of The Adventures of Noko Mashaba (2013) by Jonas Lekganyane Seal Team (2021) by Triggerfish, followed by a practice-led reflection analysis on the creation of Midnight Escapade. The study is guided by the social identity theory relative to animations’ ability to represent social and cultural identities. Through this analysis, an attempt will be made to assess the current state of representation within South African animation and whether it represents a uniquely South African Identity while attempting to answer the question; to what extent does South African animation explore cultural themes of identity and representation unique to South Africa?
Factors influencing intention and uptake of COVID-19 vaccines on the African continent: a scoping review.
Authors:   , Naidoo Damian
Published: February 2024

The COVID-19 pandemic is a severe concern worldwide, particularly in Africa. Vaccines are crucial in the fight against the COVID-19 pandemic. This scoping review examined existing literature on factors influencing intention and uptake of COVID-19 vaccines in Africa. Arksey and O'Malley's five-stage methodological paradigm was applied. A comprehensive search was undertaken from October 1st to 13th, 2021, using EBSCOhost, PubMed, Web of Science, and Google Scholar regarding the factors influencing intention and uptake of COVID-19 vaccines for studies conducted in Africa. A total of fifty published academic articles were reviewed, with many conducted in Nigeria and Ethiopia. The data analysis revealed five themes: attitudes & perceptions towards COVID-19 vaccines, intention to uptake COVID-19 vaccines, factors associated with acceptance/non-acceptance, socio-demographic determinants affecting the intention and uptake, and information sources for COVID-19 vaccines. The intention for uptake ranged between 21% and 90.1 %. Factors that promoted vaccine acceptance included confidence in the COVID-19 vaccine and the desire to protect vulnerable people. Age and sex were the most common factors significantly associated with vaccine acceptance. In contrast, most studies revealed that respondents' primary reasons for non-acceptance were safety and effectiveness concerns. The primary source of knowledge for the COVID-19 vaccines came from mass and social media. The vast majority of studies examined revealed that considerable barriers to vaccine uptake exist in Africa, contributing to the public's apprehension in this regard and resulting in a suboptimal uptake intention. To encourage vaccine uptake, governments should pay attention to refuting misinformation through integrated community-based approaches.
L1-L2 congruency as a criterion to identify collocations based on contrastive analysis
Authors: Barghamadi Maryam , Rogers James , Arciuli Joanne , Han Weifeng , Muller Amanda
Published: February 2024

In lexicon studies, L1-L2 congruency refers to the similarity in form and meaning of the way a word or phrase is said between two languages. If there is low L1-L2 congruency, the learning burden of a word or phrase can be higher. For example, an unacceptable structure could be produced when L2 (second language) learners directly use translation strategy to formulate English multiword units (MWUs). Thus, it would be ideal if such language items were identified and teachers brought students’ attention to them. This current study will use L1-L2 congruency as a criterion to identify English MWUs with low congruency with their Persian equivalents to create a resource for Persian-speaking English learners. A L1-L2 contrastive analysis was conducted on Rogers’ (2017) list of approximately 11,000 high-frequency MWUs. This list was translated, and the items were given ratings regarding their congruency in Persian. The results revealed that more than 60 per cent of the items examined were incongruent with their translations, demonstrating that L1-L2 congruency is a significant factor in selecting MWUs for Persian-speaking English learners. Thus, this study indicates that to avoid errors in MWU production, focusing on incongruent items may be beneficial for such learners.
Dynamics of change in the number of amphibian larvae in pond conditions and factors determining it in the central part of Belarus
Authors: Korzun J. V. , Kulikova A. A.
Published: February 2024

The aim of the work is to study the influence of factors of abiotic and biotic origin on abundance, growth rate and development of amphibian larvae in natural conditions.

The scientific novelty of the work lies in studying the degree of interaction of amphibian larvae with each other and with invertebrate predators, their interaction in natural conditions. The main part of the work contains a literature review, the work methodology and the result description.

In conclusion, it was noted that under natural conditions, the magnitude of impact of predators on the number of amphibian larvae is much lower than it has been previously thought; they are not able to provide a significant function of regulating the number of tadpoles. Abiotic environmental factors, being within the optimum limits, do not affect the mortality of larvae, and food in natural water bodies is not a factor limiting abundance. The most intensive death of larvae occurs in the early larval development stage. Despite a low overall density of larvae in a natural water body, most amphibian larvae are periodically exposed to metabolites and are affected by the “group effect”. This is expressed in the inhibition of growth and development of individuals, the death or decrease in the decline in the viability of the most sensitive individuals, and also increases the likelihood of their death from other factors.

Published: February 2024

Currently, a number of fish farms operate in the Kaliningrad region, which specialize in breeding aquaculture objects, including common carp (Cyprinus carpio Linnaeus, 1758) and clariid catfish (Clarias gariepinus Linnaeus, 1758) and their further sale in live or chilled whole form. There is not complex processing, as a rule. The paper shows the need for biotechnological processing of aquaculture and ways to use the waste obtained during filleting for production of minced fish and, later, minced semi-finished products. The lack of integrated use of waste from fish processing industries is a common problem in the fishing industry, so the need to solve this problem is obvious. For the efficient processing of fish raw materials, it is necessary to create a technology that will make it possible to maximize the use of waste from fish production, including the use of biotechnological methods, but at the same time ensure high quality of finished products. The paper presents the mass composition of common carp (Cyprinus carpio Linnaeus, 1758) and clariid catfish (Clarias gariepinus Linnaeus, 1758), developed a technological diagram for the complex biotechnological processing of aquaculture objects in the conditions of small enterprises of fish processing farms, proposed a description of technological processes and a machine-hardware diagram. Integrated technology implies the presence of the main and additional production. An additional diagram is associated with the production of imitation fat, the basis for which can be ground fat-containing components pre-treated with enzymes, such as tioshka and milk, as well as fish broths obtained by cooking collagen-containing components (heads, fins, tails). This technological approach can be used in the conditions of “Belvodkhoz” enterprises engaged in the cultivation and subsequent processing of aquaculture objects, for example, Fish Farm “Volma”.

At the same time, the need for the final development of historical centers, bringing them to the modern requirements of comfort, accompanied by interference in the historical context, pose the task of developing principles and approaches to combining the “old” and “new”, taking into account the categories of “integrity”, “value”, “authenticity”, “spirit places” (genius loci) of the historical environment of the city and contributing to the continuity of urban development.

The purpose of the article is to highlight the current principles and approaches to architectural activity in the current urban environment, as well as to identify the prerequisites for their formation.

Based on the methods of historical research of the evolution of theoretical foundations in the field of preservation and development of historical centers of cities, the development of architectural trends of the XX century and architectural and artistic analysis of modern world design practice, the following prerequisites for the formation of modern approaches to the connection of the “old” and ”new” historical environment are identified: the development of theory and practice in the field of preservation of architectural heritage (approval of the categories “monument”, “authenticity”, “value”, “spirit of the place”, “layers of time”, etc.); the development of modernist architecture (the concept of the correspondence of architecture to its time); the development of postmodern architecture (the emergence of a modern approach, appeal to the styles of the past, “stylization”); the development of digital design technologies at the turn of the XX–XXI centuries (new possibilities of shaping, de-constructivism, nonlinear parametric architecture). The following principles of formation of approaches of modern project activity in the historical urban environment are highlighted: subordination to context (environmental approach, “stylization”); subordination of “old” and “new” (conceptual approach or equality of “old” and “new”); independence (contrast of “old” and “new”).

Published: February 2024

Еmphasizes the increasing role of the constitutional economy in regulating economic relations and ensuring the economic security of the state in the face of new challenges and threats. It is stated that the Constitutional Court of the Republic of Belarus in its decisions consistently focuses on the formation of a constitutional economy as the most important component of the social rule of law and the constitutional value that determines the economic development strategy. At the same time, the lack of development of this issue by Belarusian science, the lack of comprehensive research in the field of constitutional economics as an interdisciplinary scientific and legal and practical direction at the intersection of law and economics is noted. In this regard, the goal was set to justify the need and give theoretical and applied prospects for the scientific support of the formation and development of the constitutional economy in Belarus. Based on the use of dialectical, general scientific and private scientific methods, including the comparative legal method, the author considers the genesis and differences of the Western and Russian schools of constitutional economics, considers its essential characteristics, analyzes the decisions of the Constitutional Court of the Republic of Belarus and the opinion of scientists on its subject and content, delineates this direction with “economic analysis of law”. According to the results of the study, the refined concept of constitutional economy as a scientific and practical direction was formulated, the main components of its concept were disclosed, among which the opposition to monopolistic activities and the development of competition were highlighted. It was proposed in the draft updated Concept of National Security to classify the formation and development of a constitutional economy as one of the main directions for neutralizing internal sources of threats in the economic sphere. The conclusion is argued about the high level of demand for scientific and applied research in the field of constitutional economics. The problem field of such studies was outlined, a set of tasks and an approximate list of program issues were developed, for the solution of which it is proposed to create a scientific school of constitutional economics in Belarus and a number of measures are given to establish it.

Abstract. Subang University has used the online Academic Information System (SIAKAD) as a technology adoption. The problem is that not all faculties use SIAKAD optimally. Therefore, it is important to find out factors that influence user satisfaction to increase user satisfaction with SIAKAD services. This research aims to provide recommendations to increase user satisfaction with SIAKAD services and enhance the efficiency and effectiveness of administrative processes at Subang University. The Unified Theory of Acceptance and Use of Technology (UTAUT) 3 and Technology Acceptance Model (TAM) methods are utilized in this study. This method model of UTAUT 3 is chosen since it has more complete variables than UTAUT 1 and UTAUT 2. This research combines the three main variables from UTAUT 3 with the two main variables from TAM. The three main UTAUT 3 variables used are the usability variable, the ease-of-use variable, and the self-motivation variable. This study tests the model using the PLS-SEM technique and SmartPLS software. Test findings show that Behavioral Intention is influenced positively and significantly by Facilitating Conditions and Performance Expectancy. Meanwhile, Use Behavior is positively and significantly impacted by Behavioral Intention.

Background: Acute Myocardial Infarction (AMI) results in a reduction in patients’ life expectancy. Different risk factors affect the risk of Major Adverse Cardiac Events (MACE). Although the role of kidney dysfunction in patients with Chronic Kidney Disease (CKD) in cardiac events has been identified, many patients with AMI are unaware of their underlying kidney disease. This study aimed to compare the incidence of adverse cardiovascular events and identify predictors of major adverse cardiovascular events in the medium term among patients with and without renal dysfunction following AMI. Methods: This retrospective cohort study was conducted on 1039 patients who were hospitalized for Acute Myocardial Infarction (AMI) between 2018 and 2019. The patient cohort comprised 314 women (mean age: 69.8 ± 13.2 years) and 725 men (mean age: 60.5 ± 13.8 years). Patient data were obtained from the registry of patients with acute myocardial infarction and the participants were followed up for a minimum of one year following hospital discharge to assess the incidence of MACE. Results: The study found that patients with a Glomerular Filtration Rate (GFR) level below 60 had a significantly higher mortality rate than those with a GFR level of 60 or above (15.7% vs. 3.5%, p < 0.0001). The multivariate analysis showed that Diabetes Mellitus (DM), GFR, and Non-ST Elevation Myocardial Infarction (NSTEMI) are significant risk factors for cardiovascular events. (p = 0.016, p = 0.015, p = 0.006 respectively), while variables such as sex, age, and Hypertension (HTN) were not significant risk factors. There was a negative correlation between GFR and death (0.241 - = r, p < 0.0001) Conclusion: This study highlights the importance of detecting kidney disease during an AMI and managing risk factors for cardiovascular disease to improve health outcomes and reduce the risk of mortality.

Meckel’s diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract. Its prevalence in the general population is 0.9-3.0%. Among the malignant neoplasms of MD, carcinoids and gastrointestinal stromal tumors are predominant. Adenocarcinomas account for less than 6.0% of all associated malignancies. We present a rare clinical case of a 67-year-old patient with gastric-type adenocarcinoma in MD, with metastatic foci in both lobes of the liver at diagnosis. This case demonstrates the diagnostic and therapeutic procedures that led to correct diagnosis and satisfactory treatment outcomes. This case emphasized the importance of using all the possibilities in the diagnosis and treatment and the necessity of cooperation with other experts in properly managing this disease. We also expressed an opinion about considering prophylactic resection of an intraoperatively discovered MD.
