Investigation of The Effects of BD35 (Biodiesel/Diesel Blend) and Propanol Usage in Combustion Characteristics in A Dual Fuel Diesel Engine
Authors: Okcu Mutlu , Fırat Müjdat , Varol Yasin
Published: June 2024

This study investigates the changes in the combustion characteristics of a diesel engine modified to operate in reactivity controlled compression ignition mode using propanol as low reactivity fuel and BD35 as high reactivity fuel. In the study, BD35 fuel, a blend of 35% biodiesel and 65% petroleum-derived diesel, was sprayed directly into the cylinder as a high reactivity fuel, while propanol was sprayed into the intake manifold at low pressure as a low reactivity fuel for reactivity controlled compression ignition. Four different low reactivity fuel premixed ratios of 0%, 15%, 30% and 45% propanol were used in the experiments. The experiments were carried out under 60% engine load and 2400 (rpm) constant engine speed conditions. According to the data obtained, it was found that the maximum in-cylinder pressure value increased with the increase in the premixed ratio and a significant increase occurred especially when 45% premixed ratio was used. Although the use of propanol as low reactivity fuel in the test engine under the reactivity controlled compression ignition concept was observed to cause a decrease in the indicated mean effective pressure, the rate of decrease in the indicated mean effective pressure was found to slow down as the premixed ratio increased. Finally, it was found that the in-cylinder gas temperature decreased significantly with increasing the propanol premixed ratio. When all the findings are analyzed, it has shown an important way to understand the effects of propanol as low reactivity fuel and BD35 as high reactivity fuel on engine performance at high load in diesel engines modified to operate in reactivity controlled compression ignition mode.
Dohodkovna neenakost, revščina in gospodarski razvoj
Authors: Steinbacher Mitja
Published: June 2024

This article discusses the relationships between economic growth, inequality and poverty. It aims at shedding some empirical and theoretical light on the call that Pope Francis made about reducing poverty by redistribution from wealthy to underdeveloped world. The article brings an overview of some of the basic factors and empirical studies of income inequality and poverty. It presents the trickle-down hypothesis about the distribution of growth and its relation to poverty reduction. It turns out that empirical studies about poverty depend on the specific collection of data from poor regions that are by its nature of collection biased downwards. Globally speaking, poverty in poor regions is in its decline and growth in its rise.
Pravna in ekonomska ureditev pravoslavne Cerkve v Kijevski Rusiji

Published: June 2024

This article brings a synthesis of the legal and economic organization of the East Orthodox Church on the territory of Kievan Rus' from the official adoption of Christianity at the end of 10th century to the middle of the 12th century. The author of this article tries to show that the strengthening of Christianity among the East Slavs was not spontaneous or accidental but rather structural, achieved primarily through cooperation between ecclesiastical institutions and political authorities. He suggests the legal and economic history of the Church in the given period be divided into two phases. The first phase corresponds to the time immediately after the official adoption of Christianity, when the political rulers were responsible for the financing of the ecclesiastical institutions; the second phase is characterized by the rise of an increasingly independent Church that was capable of supporting itself also with its own sources of income.
O prevpraševanju izgubljene preteklosti: socialistična Jugoslavija in jugonostalgija
Authors: Petelin David
Published: June 2024

An overview of the sources of nostalgia after the socialist past in today’s Eastern Europe points out the need for contributions that directly address the relationship between the present and the social changes in the (post) socialist period. Various memories originating from different perspectives suggest by themselves the necessity to revise the universal experience of social transformation, which was directed by the state power. The focus on the transformation of the former everyday life brings forth a new look at some social and economic policies in the socialist regimes in order to transform our understanding of the nature of socialism. Through the concepts of Yugonostalgia, Titoism and new Yugoslavdom, we refer to the reminiscences of life in socialist Yugoslavia; all this has already been the subject of numerous academic debates for decades. In the analysis of the common Yugoslav history, there is, in addition to the objective facts, also a symbolically reconstructed and idealized past. In all the former Yugoslav republics, in general, the image of socialist Yugoslavia is more positive for ordinary people than at the official state level. After the collapse of socialism, the framework of memory and the sense of social correctness also changed significantly. The memory of this period is not static, not only because of changes within capitalism, which reflects socialism, but also because each new generation has new experiences and therefore a different view of the past.
Healthcare provider's experience and attitude towards the national health insurance program of Nepal
Authors: Shrivastav Ganesh Kumar , Wungrath Jukkrit , Singweratham Noppcha
Published: June 2024

Background: Universal Health Coverage (UHC) aims for accessible quality healthcare for all, without financial strain. Nepal's National Health Insurance Program (NHIP), launched in 2016, strives towards this goal by offering extensive healthcare services and financial protection against severe health costs. However, the NHIP encounters challenges, particularly with reimbursement processes and operational efficiency, which may impact its effectiveness and long-term viability.
Objectives: This study analyzed the situation regarding the experience, attitude, and recommendations of government and non-government Health Care Providers (HCPs) regarding the NHIP.
Methods: This Qualitative study carried out a qualitative analysis via in-depth interviews with 12 HCPs across three Nepalese provinces, assessing their experiences with the NHIP. Our method involved a culturally validated interview guide with 21 detailed questions. Interviews, conducted in Nepali, were translated and analysed through open coding to highlight key themes related to the NHIP's effectiveness and challenges.
Results: Aiming to assess the NHIP's service delivery impact, this study selected participants involved in the NHIP and analysed interview data to uncover themes concerning the NHIP's benefit package, the Insurance Management Information System (IMIS), coordination, and claim and reimbursement processes. The study revealed that the healthcare providers recognized the NHIP's benefits in increasing healthcare access and reducing financial burdens in Nepal yet point out limitations in covering complex diseases and financial sustainability for healthcare facilities. Key challenges include technical issues with IMIS and insufficient support from the Health Insurance Board [HIB].
Conclusion:  Recommendations for enhancing the NHIP involve speeding up reimbursement, improving IMIS functionality, better coordination with the HIB, and revising the benefit package. Despite progress, significant hurdles in implementation and efficiency persist. Addressing these issues requires a multifaceted approach, including technological upgrades, policy adjustments, and enhanced training for healthcare workers. Optimizing the NHIP is essential for Nepal to achieve its UHC goals, ensuring equitable, accessible, and quality healthcare for all its citizens.
Factors associated with fruit and vegetable consumption among people in the highest risk area for Cholangiocarcinoma in Thailand
Authors: Sungtong Natpapat , Raksilp Monthicha , Songserm Assoc. Prof. Nopparat
Published: June 2024

Background: Over the past 30 years, the incidence of cholangiocarcinoma (CCA) in the Northeast of Thailand has been high and has tended to increase. Fruits and vegetables (FV) were accepted as protective factors against CCA. The prevalence of FV consumption among Northeast people is lower than recommended, which is a significant health problem that must be urgently solved.
Objectives: This study investigated the factors associated with FV consumption among people in Ubon Ratchathani, one of the high-risk areas of Thailand.
Methods: A multi-stage sampling method was used to select the population aged 40 years and over. Data were analyzed using descriptive and inferential statistics. A logistic regression analysis was performed to identify the factors associated with FV consumption.        
Results: Out of the total 744 respondents, only 11.83% consumed FV according to the standard of <400 grams/day. The bio-social factor regarding an average family income of more than 15,000 Baht had a 10.54 times greater effect on FV consumption (AOR=10.54, 95% CI: 7.59-20.57). Purchasing FVs from mobile sales trucks (AOR=4.11, 95% CI: 1.69-9.97) and receiving information from radio (AOR=1.97, 95% CI: 1.14-3.39) were associated with standard FV consumption. However, a good level of attitude had decreased the risk of FV consumption (AOR=0.30, 95% CI: 0.18-0.49).
Conclusion:  The prevalence of FV consumption among the study population is considerably low. Family income, purchasing from mobile sales trucks, receiving information from radio, and having a positive attitude were associated with standard FV consumption among people in Thailand's highest-risk area for CCA. Relevant organizations should organize activities to provide people of every economic status with knowledge and attitude on FV consumption via radio or social media and support access to quality and safe mobile sales trucks to meet consumption standards and prevent as well as reduce the risk of CCA.

Authors: Peredo Pombo José , Fojón Lagoa Enrique
Published: June 2024

Se cumplen dos años de la invasión rusa de Ucrania que trajo de nuevo la guerra a territorio europeo. Los bombardeos y muertes en las calles ucranianas no se concebían en la Europa actual. La Unión Europea se creó para buscar la paz con un ADN de potencia normativa y comercial, que carece de poder duro militar. Sin embargo, las circunstancias cambian. Los autores del libro analizan el despertar geopolítico de una Europa que debe aprender a hablar el lenguaje del poder y las repercusiones que ha tenido la guerra en Ucrania a nivel político, militar, medioambiental y con los refugiados. Un escenario nuevo, en un momento de cambio en el proceso de globalización, que obliga a Bruselas a apostar por una autonomía estratégica abierta a nivel sanitario, alimentario y energético. Una Europa que se reindustrializa frente a China y Estados Unidos, a la vez que flexibiliza su política de competencia y busca un mandato nuevo para el Banco Central Europeo en tiempos de guerra. La presidencia española de la Unión Europea, que se abrió con una visita a Kyiv y se cerró con la apertura de las negociaciones de adhesión a Ucrania, ha mantenido la unidad de los 27 frente a la Rusia de Putin.

Kesatuan Eklesial di Tengah Budaya Individual Berdasarkan Filipi 2:1-4
Authors: Kalaka Jhon
Published: June 2024

Budaya individualisme yang semula dikenal masif di dunia Barat perlahan mulai merata ke berbagai belahan dunia. Sikap semacam itu rupanya juga telah bersarang di kehidupan gereja masa kini. Individualisme mengarah pada narsisme dan pengabaian seorang akan yang lain. Namun kondisi ini sebetulnya bukan perkara baru. Di zaman gereja mula-mula telah ada hal semacam ini. Nasihat untuk kesatuan dalam Surat Filipi ditulis oleh Paulus untuk menangani adanya individualisme di antara jemaat Filipi yang menimbulkan perpecahan. Artikel ini  meneliti Filipi 2:1-4 dalam perspektif eklesiologis guna menunjukkan bahwa Paulus membahas kesatuan eklesial yang pada gilirannya dapat dipakai untuk menangani gaya hidup individualistik. Pertanyaan penelitian yang layak diajukan ialah: apa saja prinsip-prinsip yang dibutuhkan untuk membangun kesatuan eklesial di tengan budaya individual? Melalui metode eksposisi dan studi literatur, ditemukan ada beberapa prinsip untuk mewujudkan kesatuan eklesial di tengah budaya individual, yakni satu dasar kesatuan, empat pilar kesatuan, tiga sifat kesatuan, dan dua sikap kesatuan.
PROFETISME GEREJA ASIA MENANGGAPI FENOMENA IN VITRO FERTILIZATION DALAM TINJAUAN TEOLOGI MORAL KATOLIK
Authors: Hasan Benedictus
Published: June 2024

The focus of this paper is the elaboration of In Vitro Fertilization and how to respond to it in the light of Catholic moral theology, particularly within the territory of the Asian Catholic Church. The author wants to see how and what basis the Catholic Church uses in response to this phenomenon. This elaboration is then continued by responding in the form of what the Church, especially the Asian Church, should do to respond to this. The method used in this writing is a critical reading of several sources in the form of Church documents, articles on In Vitro Fertilization and several supporting sources. The findings of this paper are that the practice of In Vitro Fertilization in addition to being medically risky for women who do so is also contrary to Catholic moral teachings that put human dignity at the center of its study. The second finding is that the Asian Church is a dialogical Church, so what the Asian Church can strive to respond to is moral dialogue within the framework of moral formation as a concrete form of the Prophetic voice of the Church.

This study aims to 1) explore the values of local wisdom Pancasila in the children's game "Bentengan" and 2) reflect on the traditional children's game "Bentengan" in the light of the philosophy that humans are Homo Ludens. The children's game "Bentengan" is one of the traditional games of East Java. Bentengan is played collectively between more than three children. Axiologically, this game has a positive character education value for children's growth and development. Due to the characteristics of this locality, “Bentengan” also contains the value of local wisdom. The methodology that I used is a philosophical-phenomenological research study with an in-depth literature study of the writings on “Bentengan”. The results are then analyzed by philosophical reflection in the light of the local wisdom of Pancasila and the thoughts of John Huizinga, Homo Ludens (Humans are creatures who play). This study found that 1) the traditional children's game "Bentengan" contains the values of local wisdom Pancasila which is positive for children's growth and development and the development of Pancasila profiles for students 2) this local game contains human anthropological characters as creatures who play, namely expressing human freedom, symbolization of human struggle, temporality-spatiality, following the rules, self-purposed game (pursuit of happiness).

Authors: Priyatno Arif Mudi , Ningsih Lidya , Noor Muhammad
Published: June 2024

This paper explores the application of machine learning in predicting stock price trends, specifically for PT Bank Central Asia Tbk (BBCA) shares, using the Random Forest Regression model and Simple Moving Average (SMA) techniques. The SMA parameters ranged from 3 to 200 days, aiding in forecasting the price trends as either rising, sideway, or declining. To achieve accurate and generalizable predictions, the data normalization process was implemented using the MinMax scaler. The methodological framework adopted a time series cross-validation (CV) approach, executed 10 times with a future test window of 40 days, ensuring the robustness and reliability of the predictive model. The model's performance was systematically evaluated based on metrics of accuracy, recall, precision, and F1-score. Results from the cross-validation series indicated varied performance, with the most notable achievements in the 9th and 10th iterations, where both demonstrated an F1-score surpassing 0.745 and 0.808 respectively, and similar levels of accuracy and recall at 0.825. These high F1-scores signify a strong harmonic balance between precision and recall, underscoring the model's capability to effectively predict the stock price movements of BBCA. The findings affirm the potential of utilizing advanced machine learning techniques like Random Forest in conjunction with SMA indicators to enhance the predictability of stock market trends, offering valuable insights for investors and financial analysts.

Influence of different population densities of Portulaca oleracea L. on growth and yield of transplanted onion Allium cepa L.
Authors: Marling Gayle Shayne , Padilla Celynne , Donayre Dindo King
Published: June 2024

Portulaca oleracea is one of the weeds of onion in the Philippines. Its negative impact on growth and yield, however, has not been quantified. An experiment was conducted to determine the influence of different density levels of P. oleracea on growth and yield of transplanted onions. The weed was allowed to grow with the onion at 0, 5, 10, and 15 plants 176 cm-2 from the day of planting until harvest. The experiment was arranged in randomized complete block design with four replications. Growth and yield of transplanted onions were influenced by different densities of P. oleracea. The fresh weight of bulbs was reduced by 32.7, 51.3, and 73.6%; the dry weight by 39.6, 59.8, and 71.9% when the weed competed at 5, 10, and 15 plants 176 cm-2, respectively. Correlation and regression analyses showed that the population density of P. oleracea were strongly, negatively correlated as well as it influenced by 98.54 and 93.45%, respectively, on the fresh and dry weight of transplanted onion. This study confirmed that P. oleracea is truly a weed of transplanted onion implying that it could potentially reduce yield if left unmanaged throughout the crop’s growing cycle. Thus, it must be managed effectively whenever seen infesting transplanted onions in the country. Although the results were obtained only under screenhouse conditions, the findings suggest the need to develop a holistic weed control strategy against the weed.
A unified stochastic framework with memory for heat index and sea level dynamics
Authors: Despi Lester Ralp , Sontousidad Jason , Elnar Allan Roy , Casas Karl Patrick , Maglasang Gibson
Published: June 2024

Monitoring temperature-dependent events is critical for understanding their dynamics since these events have an impact on both animal and human habitation. It is common to see analysis of heat index and sea level that are described separately although these events have a direct connection to temperature. Often these analyses are less effective and less reliable in describing its dynamics vis-à-vis redundancy, flexibility, accounting of uncertainties and optimization. Since both are temperature-dependent events, a unified stochastic model with memory was derived. These events can be effectively described with a collective memory function (𝑇−𝑡)𝜇−12𝑒−𝛽2𝑡 𝑡𝜇+12, modifying the Brownian motion. A good match between the empirical and theoretical MSDs for both heat index and sea level was obtained with memory parameters 𝜇𝐻𝐼=1.0460 and 𝜇𝑆𝐿=1.0894 , respectively. With μ > 1, heat index and sea level exhibited long-term memory characteristics which have important implications for large timescale prediction. Similarly, analyses using a unified model are simplified and may provide the interrelatedness of these events.
Numerical modeling of the drying behavior of Adlai (Coix lacryma-jobi L.) grain
Authors: Ante Alvin , Elepaño Arnold , Yaptenco Kevin , Suministrado Delfin
Published: June 2024

The study aimed to develop computational fluid dynamics (CFD) models for simulating the drying performance of Adlai grain during convective drying with an air temperature range of 30°C to 60°C at around 10% to 80% relative humidity (RH). Before CFD modeling, the calculation of selected thermophysical properties of Adlai through mathematical modeling of its food constituents and thin-layer drying experiments were conducted. The simulation of heat and mass (moisture) transfer and visualization of moisture and temperature gradients in Adlai grain during drying were carried out using Analysis Systems (Ansys) Student 2020 R2 software package, specifically the Fluent solver. Results showed that the CFD models exhibited good agreement with the actual drying performance of Adlai. The models were validated using three statistical parameters: coefficient of determination (R2), standard error (S), and percent mean deviation modulus (P%). The R2 values ranged from 0.94-0.98; the S values ranged from 0.0018-0.0066; and the P% values ranged from 6.5%-8.68%. Overall, the models were deemed acceptable in estimating the moisture content of Adlai due to high R2 values, low S values, and P% values of less than 10%. The results validate the use of CFD as a reliable method for predicting the drying performance of Adlai, which contributes to the optimization of the drying process, the improved designing of drying systems, and the enhancement of product quality.

Published: June 2024

The Makiling Botanic Gardens (MBG) is an educational and eco-tourism site located within the vicinity of Mount Makiling, a dormant volcano susceptible to landslides, and located less than 20 km away from at least two tectonic faults. The study assessed the seismic-induced landslide hazards in the recreational area of MBG mainly based on three parameters: factor of safety (FS), yield acceleration (ay), and slope displacement (Dn). Dynamic Cone Penetration Test (DCPT) served as the primary method for obtaining the shear strength of the soil within the area. Meanwhile, other relevant parameters, including material unit weight and internal angle of friction, were determined through laboratory testing, correlations, and available data and models. Moreover, the Peak Ground Acceleration (PGA) and Spectral Acceleration (SA) values were obtained through an interpretation of a probabilistic seismic hazard analysis (PSHA) study of the Philippines. Using the ArcGIS software, an FS map, yield acceleration map, and slope displacement map were generated. Results showed that the slopes within the area exhibit static stability. However, in the event of an earthquake, it is expected that the amplified PGA will exceed the expected yield acceleration values of the slopes in some parts of the recreational area, which could result in dynamic instability and slope displacements as high as 130 mm. Thus, the recreational area of MBG possesses some susceptibility towards a seismic-induced landslide.

Syzygium lineatum is traditionally used by Filipinos as an anticancer regimen and food flavouring in the Philippines. However, its medicinal potential is yet to be validated. Herein, we report the antiproliferative and cytotoxic activities of S. lineatum extracts, sub-extracts, and alkenylated phenolic constituents gingkol (1) and bilobol (2) along with β-sitosterol (3) and a mixture of fatty acids (4–6) in vitro and in silico. Fractions 2 and 4 (SlPE4) from the biologically active petroleum ether sub-extract (SlPE), showed moderately strong antiproliferative activity against chronic myeloid leukemia (CML) cells (K-562). Chromatographic purification of fraction SlPE4 yielded antiproliferative compounds 1 and 2 against K-562 cells while SlPE2 afforded 3–6. Bilobol (2), an alkenylated resorcinol, showed better selectivity in vitro compared to the phenolic congener, gingkol (1) highlighting the importance of increased hydroxylation in the aromatic structure of the compounds. To elucidate their putative mechanisms of action, molecular docking studies were performed versus establishing the CML targets BCR::ABL1 tyrosine kinase, c-Src kinase, and protein kinase B. In silico results showed moderate to good binding affinities of 1 and 2 in the active sites of the target kinases. Overall, the study validates the purported Philippine traditional anticancer use of S. lineatum, especially its constituents gingkol (1) and bilobol (2).

Compounds synthesized from carbohydrate substrates have yielded promising lead molecules for pharmaceutical developments, as many are approved for the clinical management of a wide range of diseases. Among them, thiourea moieties are the gold mines of antibacterial molecules. In view of the lack and need for new antibiotics, a series of 16 D-fructose-based thiourea compounds were synthesized from asymmetric aldol reaction and isopropylidenation. The new compounds were established from nuclear magnetic resonance, Fourier-transform infrared, and electrospray ionization mass spectrometry. Using disk diffusion assay for antibiotic susceptibility, four of the novel compounds were found to have concentration-dependent antibacterial activities. The addition of trifluoromethyl groups at the meta-position on the phenyl ring of the thioureas appeared to promote bacterial inhibitory action. Thiourea 2a exhibited the most potent activity against the Gram-negative species, Klebsiella pneumoniae, Escherichia coli, and Salmonella typhi, as well as the Gram-positive species, Micrococcus luteus; but not against all bacteria tested. Thiourea 2b and 3a had lower efficacy but showed better broad-spectrum activity against most bacteria tested. Thiourea 3b displayed species-specific activity only against K. pneumoniae and S. typhi. Our findings show the benefits and prospects of synthesizing new carbohydrate compounds for therapeutic medication.

Amphibians are experiencing declines globally, with emerging infectious diseases as one of the main causes. Haematological parameters present a useful method for determining the health status of animals and the effects of particular diseases, but the interpretation of differential cell counts relies on knowing the normal ranges for the species and factors that can affect these counts. However, there is very little data on either normal haematological parameters or guides for blood cell types for free-ranging frog species across the world. This study aims to 1) create a visual guide for three different Australian frog species: Litoria paraewingi, Limnodynastes dumerilii, and Crinia signifera, 2) determine the proportions of erythrocytes to leukocytes and 3) differential leukocytes within blood smears from these three species and 4) assess the association between parasites and differential counts. We collected blood samples from free-ranging frogs and analysed blood smears. We also looked for ectoparasites and tested for the fungal disease chytridiomycosis. Overall, we found that the differentials of erythrocytes to leukocytes were not affected by species, but the proportions of different leukocytes did vary across species. For example, while lymphocytes were the most common type of leukocyte across the three species, eosinophils were relatively common in Limnodynastes dumerilii but rarely present in the other two species. We noted chytridiomycosis infection as well as ectoparasites present in some individuals but found no effect of parasites on blood parameters. Our results add baseline haematological parameters for three Australian frog species and provide an example of how different frog species can vary in their differential blood cell counts. More information is needed on frog haematological data before these parameters can be used to determine the health status of wild or captive frogs.

O presente estudo tem o objetivo de realizar previsão de roubos de carga no Estado de São Paulo, e verificar o melhor modelo para cada região do Estado. Para alcançar o objetivo foi realizado a previsão com séries temporais, através do software Crystal Ball e da linguagem de programação Python com a biblioteca PyCaret. Através da aplicação das ferramentas foi possível analisar variados modelos e selecionar os melhores, com isso os escolhidos para as previsões foram o modelo ETS, para a Capital Paulista, e SARIMA, para a região da Grande São Paulo, pois estes proveram resultados mais satisfatórios para as regiões em estudo, apresentando MAPE de 9% e 7,45% respectivamente. Espera-se que as previsões possam nortear planejamentos logísticos e gerenciamento de riscos, que possibilite a diminuição do roubo de carga, e consequentemente a diminuição dos custos por esse tipo de perda, que geram grandes prejuízos para as empresas e é um desafio para o transporte de carga no Brasil.

Published: June 2024

Há várias alternativas de manejo que buscam aperfeiçoar o desempenho reprodutivo e produtivo do rebanho, visando maior lucratividade e o mínimo de degradação ambiental, contudo a pesquisa de campo mostrou que os pequenos produtores observados neste estudo, não conseguem evoluir seus sistemas produtivos. Este artigo tem por objetivo geral analisar como a introdução de genética “verdadeiramente” de corte, a gestão cuidadosa de investimentos e cuidados com a aversão ao risco, produzem uma melhora dos resultados na produção, para que esse possa introduzir um modelo que o ajude a tornar a produção mais lucrativa. O procedimento metodológico envolveu a pesquisa bibliográfica e aplicação de questionário com pequenos produtores do setor em análise. O trabalho mostra que, ao adotar o modelo de Pecuária Mista sugerido, o pequeno produtor de leite, pode garantir a melhor conversão dos animais de leite e sem aptidão para leite, gerando mais produtividade do rebanho e consequente ganho de rentabilidade, bem como usar melhor os recursos naturais e as aptidões da propriedade, contribuindo para maximizar ainda mais os resultados.

The physical appearance of food has a significant impact on its consumption and economic value. Research indicates consumer dissatisfaction with the quality of the tomatoes found in commerce. Physical appearance is the main characteristic that causes dissatisfaction among consumers looking for unblemished fruits. In view of this, this work aims to create a parametric model for the 3D printing of tomato fruit development that helps the producer identify the development phases of their production and compare the morphological characteristics of the fruits. For this purpose, daily experimental data on fruit growth were extracted, in addition to photographic records. In this study, a model was developed that describes the growth of fruits of the hybrid saladette tomato SM-16. This model simulates the daily growth behavior of these fruits. The mathematical and computational modeling was developed using the Python programming language and two other free software, Octave and Inkscape. The growth of the tomato is represented by a logistic model, while the shape of the fruits during growth is a model developed in Artificial Neural Network. The models used, adjusted to the parameters found, proved to be adequate to describe the growth behavior of the tomato fruits of the variety studied over time.
