Authors: Suarez Franco Marcelo , Bruno Cecilia , Giménez Pecci María de la Paz , Balzarini Mónica
Published: March 2024

Hoy es posible acceder fácilmente a cuantiosos volúmenes de datos climáticos georreferenciados. Estos pueden ser usados para modelar la relación entre condiciones climáticas y enfermedad, para lo cual es necesario usar múltiples variables meteorológicas, usualmente correlacionadas y redundantes. La selección de variables permite identificar un subconjunto de regresoras relevantes para construir modelos predictivos. Stepwise, Boruta y LASSO son procedimientos de selección de variables de distinta naturaleza por lo que su desempeño relativo ha sido poco explorado. El objetivo de este trabajo fue la comparación de estos métodos aplicados simultáneamente en la construcción de modelos de regresión para predecir riesgo de enfermedad desde datos climáticos. Se utilizaron tres bases de datos georreferenciados con valores de presencia/ausencia de distintos patógenos en cultivos de maíz en Argentina. Para cada escenario se obtuvieron variables climáticas del periodo previo a la siembra hasta la cosecha. Con los tres métodos se generaron modelos predictivos con precisión de clasificación cercana al 70 %. LASSO produjo mejor predicción, seleccionando una cantidad intermedia de variables respecto a Stepwise (menor cantidad) y a Boruta (mayor). Los resultados podrían extenderse a otros patosistemas y contribuir a la construcción de sistemas de alarma basados en variables climáticas.

Published: March 2024

One of the most important challenges in the production of gluten-free foods is the need to improve their nutritional quality. This work attempts to produce gluten-free noodles by substituting three different percentages of corn flour with hemp and to evaluate their technological and nutritional quality. This study used corn flour with 10.33 % protein and 1.57 % fiber and commercial hemp flour with 23.57 % protein and 28.75 % fiber. The pastas were made by extrusion by adding pregelatinized starch, ovalbumin and salt to obtain the control, then substitutions were made with 5 %, 10 % and 15 % hemp flour. The addition of hemp flour did not significantly affect the most important quality indicators, such as optimum cooking time and cooking residue, and even increased the firmness of the cooked pasta. Protein and fiber content increased significantly. It can be concluded that the addition of these percentages of hemp flour does not produce a deterioration of the technological quality of gluten-free pasta and allows for an increase in fiber and protein content, generating a significant improvement of nutritional quality.
Turbulence and mixing from neighbouring stratified shear layers
Authors: Liu Chih-Lun , Kaminski Alexis , Smyth Bill
Published: March 2024

Studies of Kelvin-Helmholtz instability (KHI) have typically modeled the initial mean flow as an isolated stratified shear layer. However, geophysical flows frequently exhibit multiple layers. As a step towards understanding these flows, we examine the case of two adjacent stratified shear layers {\color{black} using both linear stability analysis and direct numerical simulation}. With sufficiently large layer separation, the characteristics of instability and mixing converge toward the familiar Kelvin-Helmholtz turbulence. Similarly, when the separation is near zero and the layers add to make a single layer, albeit with a reduced Richardson number. Here, our focus is on intermediate separations, which produce new and complex phenomena. As the separation distance $D$ increases from zero to a critical value $D_c$, approximately half the thickness of the shear layer, the growth rate and wavenumber both decrease monotonically. The minimum Richardson number is relatively low, potentially inducing pairing, and shear-aligned convective instability (SCI) is the primary mechanism for transition. Consequently, mixing is relatively strong and efficient. When $D\sim D_c$, billow length is increased but growth is slowed. Despite the modest growth rate, mixing is strong and efficient, engendered primarily by secondary shear instability (SSI) manifested on the braids, and by SCI occurring on the eyelids. Shear-aligned vortices are driven in part by buoyancy production; however, shear production and vortex stretching are equally important mechanisms. When $D>D_c$, neighbouring billow interactions suppress the growth of both KHI and SCI. Strength and efficiency of mixing decrease abruptly as $D_c$ is exceeded. As turbulence decays, layers of marginal instability may arise.

Authors: Ghania Kihal  , Djamila Rouag saffidine
Published: March 2024

Due to their high energy consumption hotel buildings have a significant impact on the environment. Such constructions are particularly energy-intensive demanding environments so as to meet the various needs of occupants and ensure their comfort. Guests tend to consume more energy during their stays than they do in their own homes (water, electricity, light, temperature...). In recent years, Algeria has seen a significant increase in the construction of hotels, many of which are concentrated in the Mediterranean region, which experiences particularly high humidity levels in the summer and winter. The new generation of building materials used to enhance comfort and reduce building energy consumption, are progressively sought after all over the world. This work, which studied the performance of silica aerogels for the glazing system of hotel rooms in a Mediterranean climate, can provide a database for hotel designers, an investigation combining experimental work (air and surface temperature measurements and thermography) and numerical simulation (using TRNsys V17) was conducted on an existing hotel building located in Béjaia. The results revealed the insertion of silica aerogel within a 6 mm thick glazing sheet decreases significantly the heating and cooling requirements of the study indoor environment.

La úlcera péptica es una enfermedad que afecta aproximadamente al 10% de la población a nivel mundial y en algunos pacientes se puede complicar con peritonitis que puede provocar incluso la muerte. Para su tratamiento existen diversos fármacos. Sin embargo, todos ellos tienen efectos adversos, por lo que es necesario buscar otras alternativas terapéuticas. El estudio de las plantas medicinales es importante ya que se consideran una fuente importante para la obtención de nuevos fármacos. En México, la Hamelia patens es utilizada de manera empírica para tratar la úlcera gástrica, pero carece de un sustento científico. Por ello, el objetivo de este trabajo fue determinar el posible efecto gastroprotector de Hamelia patens usando el modelo de lesiones gástricas inducidas por etanol en ratas Wistar. A partir de las hojas de Hamelia patens se prepararon los extractos de hexano, diclo-rometano y metanol vía maceración. Los extractos se administraron vía oral a las dosis de 10, 30 y 100 mg/kg, y carbenoxolona (fármaco de referencia) a las dosis de 3-100 mg/kg. El extracto más activo se separó por cromatografía en columna y se obtuvieron 4 fracciones, que fueron evaluadas a la dosis de 100 mg/kg. Los resultados demostraron que los extractos de diclorometano y metanol fueron activos en las tres dosis evaluadas, respecto al extracto hexánico solo presentó actividad a la dosis más alta (100 mg/kg). A la dosis de 10 mg/kg el extracto de diclorometano fue más eficaz que la carbenoxolona a la misma dosis (p<0.05). Tres de las cuatro fracciones del extracto de di-clorometano, resultaron con actividad gastroprotectora (p<0.05) con valores de índice de úlcera de 42, 37 y 55 mm2, respectivamente. En conclusión, Hamelia patens demostró actividad gastroprotectora en ratas Wistar del daño gástrico causado por etanol y demostró tener más de un compuesto activo.

A weighted Gompertz-G family of distributions for reliability and lifetime data analysis
Authors: EGHWERIDO Joseph Thomas , NZEI Lawrence
Published: March 2024

This article is set to push new boundaries with leading-edge innovations in statistical distribution for generating up-to-the-minute contemporary distributions by a mixture of the second record value of the Gompertz distribution and the classical Gompertz model (weighted Gompertz model) using T-X characterization, especially used for two-sided schemes that provide an accurate model. The quantile, ordinary, and complete moments, order statistics, probability, and moments generating functions, entropies, probability weighted moments, Lin’s condition random variable, reliability in multicomponent
stress strength system, reversed, and moments of residuals life and other reliability characteristics in engineering, actuarial, economics, and environmental technology were derived in their closed form. To investigate and test the flexibility, viability, tractability, and performance of the proposed Weighted Gompertz-G (WGG) generated model, the shapes of some sub-models of the WGG model were examined. The shapes of the sub-models indicated J-shapes, increasing, decreasing, and bathtub hazard rate functions. The maximum likelihood estimation of the WGG-generated model parameters was examined. An illustration with simulation and real-life data analysis indicated that the WGG-generated model provides consistently better goodness-of-fit statistics than some competitive models in the literature.

Published: March 2024

In this manuscript, the strain wave equation, which plays an important role in describing different types of wave propagation in microstructured solids and the (2+1) dimensional Bogoyavlensky Konopelchenko equation, is defined in fluid mechanics as the interaction of a Riemann wave propagating along the $y$-axis and a long wave propagating along the $x$-axis, were studied. The generalized Kudryashov method (GKM), which is one of the solution methods of partial differential equations, was applied to these equations for the first time. Thus, a series of solutions of these equations were obtained. These found solutions were compared with other solutions. It was seen that these solutions were not shown before and were presented for the first time in this study. The new solutions of these equations might have been useful in understanding the phenomena in which waves are governed by these equations. In addition, 2D and 3D graphs of these solutions were constructed by assigning certain values and ranges to them.
Fractional approach for Dirac operator involving M-truncated derivative
Authors: ERCAN Ahu
Published: March 2024

In this study, we examine the basic spectral information for systems governed by the Dirac equation with distinct boundary conditions, utilizing a modified form of local derivatives known as M-truncated derivative (MTD). The spectral information discussed includes the representation of solutions in the form of integral equations, the asymptotics vector-valued eigenfunctions and eigenvalues, and their normalized forms, all within the context of the MTD method that incorporates truncated Mittag-Leffler functions. This type of MTD provides the features of integer-order operator theory. Also, by virtue of the parameters $\alpha $ and $\gamma$, we analyze and compare the solutions with graphs in terms of different potentials, different eigenvalues and different orders. Thus, the aim of this article is to consider spectral structure of Dirac system in frame of M-truncated derivative by proping with visual analysis.
Pemidanaan Terhadap Mucikari Ditinjau dari Asas Keadilan dalam Kasus Trafficking Anak

Published: March 2024

There are many cases of illegal exploitation that occur now based on paper and electronic media reports and many examination results show that cases of illegal exploitation, especially of women and children, need attention. Dealing with women and children in Indonesia generally involves prostitution and pornography. The occurrence of sexual trafficking involving girls reveals violations of women's human rights, depriving them of the opportunity to experience peace and happiness from a young age. Their basic rights to live freely and protect themselves from potential harm have been reduced due to criminal activities. These incidents show a correlation between the trafficking of underage girls (through prostitution) and other sexual offenses such as assault and battery. Many minors and adult women are victims. Brutality against women is thought to stem from a framework that considers women as weak and substandard individuals compared to men. Overall, victims of human trafficking, especially women involved in prostitution and children forced to work, are victims of crime and not perpetrators of crime.

Why Mature Galaxies Seem to Have Filled the Universe Shortly After the Big Bang — A New Cosmological Model, that Predicted the JWST Observations
Authors: Pletcher Arthur
Published: March 2024

The Azimulthal Hyper-Projection (AHP) onto spacetime Model of Cosmology is just an extension of the familiar Atlas map of a globe in geography. The Atlas is an azimuthal projection of 3 spacial dimensions projected onto a 2 dimensional plane. The important feature of an Atlas is that the geometry expands asymptotic toward the horizon, and is therefore POSITIONALLY DEPENDENT, such that if North America is centrally positioned, then Siberia and Alaska are viewed as extremely remote. Thus if the Bering Strait were centrally positioned, then longitudinal meridians of North America would likewise be viewed as being remotely separated. AHP extends this concept to a hyper-projection of 5 dimensions onto spacetime. However as viewed in spacetime, geodesics appear to be expanding outward in 3 dimensional space away from the observer. Thus by extension, AHP is also POSITIONALLY DEPENDENT, such that the separations between remote galaxies appear (measures) to be much greater than they would appear from their mutual local group, and vice versa our local group of galaxies would appear to be mutually separated with extreme distances from a remote perspective. A proposed experiment (figure 14) is offered to prove that two separated objects, as measure from a remote distance \((\sim 40 AU)\) are greater than their respective distance, as measured locally.

Red-shifting is alternatively proposed as azimuthal angular projections of wavelengths \(\lambda\). Magnitude is alternatively proposed as a function of Lambert's cosine law of illumination, over expanding geodesics. From established \(z\) values, the Universal hypersphere is calculated (figure 9). A function of this projected hypersphere is shown to match the Universal expansion rate, as established from supernova cosmology survey points, and also satisfies the Cosmological Constant \(\Lambda\), without dark energy. Flattened galaxy rotation curves are simply and accurately explained as measured expanding geodesics and apparent increasing density, along the observer's line of sight (figure 11, equation 20). As well, this model provides a reasonable explanation of the James Web Space Telescope findings: of maturely developed galaxies at the time of the early universe. The justification of such a radically novel model is from recent observations from the first dataset, provided by NASA's James Webb Space Telescope (JWST) of six massive galaxies, at a time in the early universe, seem to defy conventional cosmological models, as they appear to be as mature and developed as our own local group. Such unexpected discoveries JUSTIFY A RADICALLY NOVEL MODEL OF COSMOLOGY. TO QUOTE JOEL LEJA, ASSISTANT PROFESSOR OF ASTRONOMY AND ASTROPHYSICS AT PENN STATE “IT TURNS OUT WE FOUND SOMETHING SO UNEXPECTED IT ACTUALLY CREATES PROBLEMS FOR SCIENCE. IT CALLS THE WHOLE PICTURE OF EARLY GALAXY FORMATION INTO QUESTION”.
The Synthetic Concept of Truth and Its Descendants
Authors: Culina Boris
Published: March 2024

The concept of truth has many aims but only one source. The article describes the primary concept of truth, here called the synthetic concept of truth, according to which truth does not belong exclusively to us nor does it belong exclusively to nature: truth is the objective result of the synthesis of us and nature in the process of rational cognition. It is shown how various aspects of the concept of truth – logical, scientific, and mathematical aspect – arise from the synthetic concept of truth. Related to these aspects, i) the regression of truth is analysed and how the distinction between assertion and valuation resolves the regression, (ii) Tarski’s definition of truth is analysed and its role in the concept of truth is identified, and (iii) the truth predicate is analysed and how the paradoxes of truth arise.

BACKGROUND: Tobacco smoking poses a significant risk for various diseases, including cardiovascular diseases, chronic respiratory diseases, and cancers. In Kenya, tobacco-related deaths contribute substantially to non-communicable disease mortality. This study aims to quantify the mortality attributed to tobacco smoking in Kenya from 2012 to 2021.

METHODS: Employing a prevalence-based analysis model, the study utilized Population Attributable Fraction to estimate age-specific Smoke Attributable Mortality (SAM) rates for individuals aged 35 years and older. Causes of death associated with tobacco use, including cancers, cardiovascular diseases, respiratory diseases, tuberculosis, and diabetes, were analyzed based on age, sex, and death records between 2012 and 2021.

RESULTS: Over the study period, 60,228 deaths were attributed to tobacco-related diseases, with an annual increase observed until 2016 and subsequent fluctuations. Respiratory diseases, diabetes mellitus, malignant cancers, tuberculosis, and cardiovascular diseases collectively accounted for 16.5% of deaths among individuals aged 35 and older. Notable contributors were pneumonia and influenza (respiratory diseases), oesophageal cancer (cancers), and cerebrovascular diseases (cardiovascular diseases).

SMOKING PREVALENCE: Smoking prevalence in Kenya indicated 17.4% of men, 0.9% of women, and 9% overall as current smokers. Former smokers constituted 10.6% of men, 1.4% of women, and 5.9% overall.

SMOKING-ATTRIBUTABLE MORTALITY: Out of observed deaths, 16.5% were attributed to smoking, with respiratory diseases (40.5%), malignant cancers (31.4%), tuberculosis (13%), cardiovascular diseases (8.9%), and diabetes mellitus (6.1%) contributing. Pneumonia and influenza, oesophageal cancer, chronic airway obstruction, and tuberculosis were primary causes, comprising 70% of all Smoking-Attributable Mortality (SAM).

DISCUSSION: The study underscores smoking's substantial impact on mortality in Kenya, emphasizing the urgency of preventive measures and tobacco control strategies. The findings highlight the differential contributions of smoking to various diseases, indicating the need for targeted interventions tailored to specific health outcomes.

CONCLUSION: Tobacco-related mortality is a significant public health concern in Kenya. Efforts should focus on preventing tobacco use and managing associated disease burdens. Smoking cessation initiatives and comprehensive tobacco control measures are imperative to mitigate the impact on population health.

Background and Objectives: The gap in noise auditory brainstem responses (GIN-ABR) is a valuable assessment tool for auditory temporal processing, offering non-invasive and objective measurements encompassing the entire auditory system from the cochlea to the brainstem. This method has been utilized in investigating various factors, including age-related effects, hearing loss, and tinnitus. This systematic review was conducted to present a thorough examination of (GIN-ABR), encompassing its methodology, applications, and inherent limitations. Methods: This study was conducted based on preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Cochrane, PubMed, and Ovid databases were used to extract English articles from 1990 to June 2023. The search terms used were “gap in noise auditory brainstem response”, “ABR gap detection”, “ABR gap duration”, “ABR gap threshold”, and “ABR temporal processing”. Articles were included if gap-evoked ABR was used, investigating the effect of any factor on the responses, and using any gapped stimulus type. Articles whose evoked potentials did not include ABR waves were excluded. The outcome of interest was gap-evoked ABR in different participant groups. Results: A total of 10 studies were deemed suitable for inclusion in the review. The articles were reviewed that including the study population, the methods, and the results. Despite the variability in the results of the studies, in the aged group, longer latency shifts and decreased peak amplitude were reported compared to the young group. Correspondence of behavioral thresholds with GIN-ABR has also been mentioned in studies. Conclusion: The GIN-ABR method has been extensively utilized in investigating various factors, including age-related effects, hearing loss, and tinnitus. Notably, GIN-ABR has several clinical advantages, such as cost-effectiveness, shorter test duration, independence from alertness levels, attention, sleep depth fluctuations, or medication. Additionally, it has shown its compatibility with psychophysical tests. Further research is warranted to explore the impact of various factors on different components of GIN-ABR. Consequently, with its promising findings and growing body of research, the gap in noise test has the potential to be gradually integrated into the set of audiological clinical evaluations.

Authors: Ostrovskyi O. Ya. , Slivinska L. G.
Published: March 2024

The biopsy is a diagnostic method that allows in vivo sampling of kidney tissue material for histopathological examination to identify structural changes in the organ. The study aims to study the informativeness of intravital diagnosis of stage II chronic kidney disease (according to IRIS) in cats based on the results of histological and histochemical studies of biopsies. A kidney biopsy was performed on two cats aged 6 and 8 years. Research methods: histological (hematoxylin and eosin, Heidenhain test) and histochemical (PAS reaction, Gomori (PAMS)). The diagnosis of chronic kidney disease was made based on history, clinical symptoms, and blood and urine test results. Based on the biopsy, acute extracapillary serous-desquamative glomerulonephritis was established in cats with II-stage chronic kidney disease, which was characterized by vacuolar dystrophy of renal tubule epitheliocytes, desquamation of glomerular capsule epithelium. In addition, lymphoplasmacytic infiltration of the renal stroma, thickening of the Shumlyansky-Bowman capsule with significant deposition of PAS-positive substances, the collapse of the glomerular loops, and focal atrophy of the proximal tubules of the kidney pronounced extra capillary desquamation of the glomerular epithelium, segmentation of the vascular glomerulus, and dystrophy of single tubules were noted. The detected changes in kidney biopsies of cats in the II stage of chronic kidney disease are characteristic of this pathology, which makes it possible to develop and carry out effective treatment of animals promptly and improve their quality of life.

The use of various active substances in the composition of biocides can affect specific chemical properties. Their compatibility, solubility, stability, and corrosion activity are investigated against the background of their ability to affect pathogenic microorganisms. Due to the obtained results, the manufacturer can offer their use in specific conditions (aerosol or wet use, the possibility of use on metal structures, etc.). This publication presents the results of the study of the physicochemical properties of the biocidal agent “Iodosan”, developed by the employees of State Scientific and Research Institute of Laboratory Diagnostics and Veterinary and Sanitary Expertise, based on iodine and lactic acid, dark yellow, with a moderate specific smell of iodine. The starting solution of the product is straightforward to slightly yellowish liquid with a mild iodine smell; after diluting it in tap water, the color of the water remains transparent. The agent is mixed with water to prepare a working solution, “Iodosan”, for wet and aerosol disinfection of objects. The biocidal agent “Iodosan” solution in concentrations of 0.2‒0.5 % has low corrosion activity against the treated test objects. According to research results, the most insufficient corrosion activity of the drug “Iodosan” for aluminum is observed at its concentration of 0.1‒0.5 %, steel, and galvanized steel ‒ 0.1‒0.2 %. Studies have shown that the disinfectant “Iodosan”has a surface tension of 62.03 mN/m at 20 °C. This proved that the drug has a good wetting ability, which affects the disinfecting properties. In working concentrations, the drug has a pH of 5.8. The research results confirmed the effectiveness of the biocidal preparation “Iodosan” for treating premises and equipment surfaces in optimal bactericidal concentrations, and it is recommended for use in production.

Roasted soybeans are a complete source of indigestible protein in the rumen, have high sanitary and hygienic indicators, are devoid of non-nutritional substances of ordinary raw soybeans. The SoyPass and RaPass technology provides all the advantages of roasting soybeans and creates prerequisites for prolonged storage of beans for up to two years without prior drying. The introduction of full-fat flattened soybeans roasted by the Roast-A-Matic roaster into the diet of dairy cows leads to an increase in their milk productivity. Certified results of chemical research show that after frying, the percentage of crude protein significantly increased (by 2.92 points, P < 0.05) and the content of total digestible nutrients (by 8.1 %, P < 0.05), urease activity decreased to 0.06 ± 0.007 units of pH. The biological value of soy protein after frying corresponds to the indicators of the reference protein. Two groups of cows were involved in the study: № 1 – high-yielding cows with a daily milk yield of 30.69–35.96 L (n = 307) and № 2 – medium- and low-yielding cows with a yield of 19.05–28.88 L (n = 377). Group № 1 was given 300 g of roasted soybeans (111 g of protein) daily in their diet instead of 250 g of a high-protein supplement (200 g of protein); group No. 2 – gradually replaced 230 g of the supplement (184 g of protein) and 1500 g of 51 % meal (765 g of protein) with 1700 g of roasted soybeans (629 g of protein). In both groups, the 65-day observation period should be divided into 2 periods: 1) a 30-day period of intensive growth with a rapid increase in milk yield (up to +24.2–25.0 %); 2) the period of stabilization (from the 31st to the 65th day), characterized by some fluctuations in the % increase in milk, but in general by reliable maximum values (up to +25.0–36.7 %). The maximum daily volume in group № 1 reached 41.83 ± 1.04 and 41.83 ± 0.3 L (Р < 0.01) on the 32nd and 38th days, respectively. At the same time, the range of the indicators of the individual yield in the group ranged from 10.7 to 11.7 L. Similar indicators for group № 2 were: 32.56 ± 2.74 L (Р < 0.025) on the 58th day and 10.4–23.8 L. So, in the first 30 days of feeding full-fat fried soybeans, there is a rapid but unstable (with fluctuating peaks) increase in milk productivity of cows. During the 2nd month of soy consumption, the maximum milk yield is reached, when the increase in added milk is not rapid, but stable. Thus, it is advisable to introduce 1.5–2.0 kg/day of roasted soybeans (equivalent to 0.3–0.4 kg of fat/day) into the diet of dairy cows.

У статті розглядаються деякі аспекти детермінації злочинності маргіналізованими групами осіб, які відповідно до міжнародно-правових актів, імплементованих до законодавства відповідних держав, визнаються мігрантами. Установлено, що залежно від тимчасової і територіальної конкретики, соціальні корені злочинності можуть набувати різний зміст, проте в більшості випадків вони включають у себе соціальну диференціацію та поляризацію суспільства, проблеми кризи системи цінностей і поведінкових установок, політичну та економічну нестабільність. Разом із тим, до соціальних коренів міграційної злочинності слід віднести культурні особливості окремих етнічних груп, їх слабке бажання активно взаємодіяти з населенням приймаючої держави, що обумовлює до маргіналізації цих груп, демонстрації злочинної поведінки своїх представників у порівнянні з іншими верствами корінного населення. Маргінальна поведінка навіть законослухняного мігранта, який має високий рівень правосвідомості, здатна стимулювати криміногенну ситуацією, обумовлену сукупністю низки негативних економічних, соціальних, політичних та інших факторів (причин), а також психологічного ставлення місцевого населення до мігранта, що утворюють сприятливі умови для вчинення кримінального правопорушення. Маргіналізація міграції може бути певним джерелом для соціальних конфліктів з місцевим населенням, спричинити делінквентну поведінку та криміналізацію приймаючого мігранта суспільства. Ключові слова: міжнародна міграція; маргіналізація особи; маргінальні групи; запобігання злочинності; детермінація злочинності; соціалізація та інтеграція.

Multivariable predictive models for the estimation of power consumption (kW) of a Semi-autogenous mill applying Machine Learning algorithms [Modelos predictivos multivariables para la estimación de consumo de potencia (kW) de un molino Semi - autógeno aplicando algoritmos de Machine Learning]
Authors: Vera Ruiz Miguel Angel , Vega Gonzales Juan Antonio , Bailon Villalba Franklin Jhoan
Published: March 2024

This research aimed to develop machine learning (ML) models to estimate power consumption (Kw) in a Semi-autogenous mill in the mining industry. Using Machine Learning algorithms considering various operating variables for the different models such as Multiple Linear Regression (RLM), Decision Tree Regression (RAD), Random Forest Regression (RBA) and Regression Artificial Neural Networks (ANN). The methodology adopted was applied, with an experimental design with a descriptive and transversal approach. The results of the application of these models revealed significant differences in terms of predictive efficiency. The RLM and RRNA stood out with coefficients of determination (R²) of 0.922 and 0.939, respectively, indicating a substantial capacity to explain the variability in power consumption. In contrast, the tree-based models (RAD and RBA) showed inferior performance, with R² of 0.762 and 0.471. When analyzing key metrics such as Mean Absolute Error (MAE), Mean Square Error (MSE) and Root Root Mean Square Error (RMSE), it was confirmed that both RLM and RRNA outperformed the tree-based models. These results support the choice of RLM and RRNA as preferred models for estimating power consumption in a Semi-autogenous mill.

The purpose of this evaluation is to determine to what extent the improvement of the transportation process based on the Lean methodology reduces environmental impacts at the SUMMA GOLD Unit. The main focus of the analysis of this research is to know, define, measure and minimize the causes of errors generated in the material transportation process in a mining unit, which in turn identifies and reduces negative environmental impacts. This evaluation is carried out using the approach of the DMAIC tool (Define, Measure, Analyze, Improve and Control), which offers a solid structure for problem solving and goes hand in hand with the Lean Manufacturing methodology. The application of the Lean methodology and the proposal to improve a technological tool managed to increase the transportation performance of each area, from 19.95% to 31.32%, obtaining as a variation 11% improvement; This increases the amount of ore produced by 3094 on average per trip. It also allows increasing the fuel use cost reduction rate from 25% to 54.91%, obtaining an improvement of 30% which translates into a reduction of 1.9 gallons per hour with a decrease in costs of S/5,616.1.

This study focuses on making a detailed description of the unit costs associated with the transportation of minerals in mining operations. The hypothesis proposed suggests that, when carrying out an economic evaluation, conveyor belts exhibit a lower present value compared to the use of trucks. The research is characterized by being applied, non-experimental and descriptive. The conclusion drawn indicates that, when contrasting these two options through an economic analysis, the conveyor belt has a reduced present value of 119 million dollars, which represents an advantage over trucks that have a present value of 164 million dollars. reflecting a difference of 39% indicating that the conveyor belt is positioned as the most beneficial option for its construction. To carry out this project, it would be necessary to have 13 trucks, as well as a stacker, a front loader and a material crusher. In contrast, an option to use trucks would require a quantity of 22 units, with a demand of 50% in present value terms compared to the conveyor belt approach.

The purpose of this study was to determine the optimal algorithm to estimate the price of gold and identify the variables most incident to its variation. An exploratory level methodology, quantitative approach and non-experimental design was used. The results obtained when performing EDA show that the variables with the highest correlation with respect to the price of gold are the cost of production with 44% and the S&P_500 with 30%. When validating the models, the result was that the Gradient boosting algorithm has an optimal R2 of 99.4%, this value justifies the importance of the model in order to estimate the price of gold. Likewise, without leaving aside the Random Forest algorithm, it also shows an R2 of 99.3%. Likewise, it was identified that the variables with the highest incidence are Cost_prod with 51.5% and USD_X with 30.4%. Finally, it is concluded that the use of these algorithms such as Gradient boosting and Random Forest can estimate the price of gold taking into account the variables that affect its variation.
