Authors: Tsuboki Shimpei , Todaka Tatemi , Hasegawa Shu , Kaku Yasuyuki , Ohmori Yuki , Mukasa Akitake
Published: April 2023

Background:

Unruptured cerebral aneurysms that lead to epilepsy are rare and olfactory hallucinations caused by such an aneurysm are extremely rare. Various treatments have been proposed, including wrapping, clipping with or without cortical resection, and coil embolization, but there is no consensus on the best approach.

Case Description:

We present a case of a 69-year-old female who experienced olfactory hallucinations caused by a posterior communicating artery aneurysm and was treated with clipping without cortical resection, with a positive outcome.

Conclusion:

According to our knowledge, there has been only one report of a posterior communicating artery aneurysm presenting with olfactory hallucinations has been reported, where clipping and cortical resection were performed. This is the first report of a posterior communicating artery aneurysm with olfactory hallucinations that was effectively treated with clipping alone. There have been a few similar reports of large middle cerebral artery aneurysms, most of which are believed to be caused by entorhinal cortex compression. Although a definitive treatment protocol for this condition remains elusive, we suggest that elimination of the pulsatile compressive stress exerted on the cerebral cortex through surgical clipping or coil embolization is crucial for achieving efficacious seizure management.
High Temperature Reaction of Individual Graphite Nanoparticles with N2O: Etching, Passivation, Sublimation, and Comparison to O2
Authors: Lau Chris , Friese Abigail , Anderson Scott
Published: April 2023

High temperature oxidation kinetics, nanoparticles, Graphite, N2O, sublimation ABSTRACT The kinetics sublimation and for reaction of individual graphite nanoparticles (NPs) with N2O were studied over the 1600 to 1900 K temperature range. Reaction with N2O etched the NP surfaces at rates that increased with temperature and were linear with N2O pressure. The etching efficiency was two orders of magnitude lower for N2O compared to O2 at 1600 K, and one order of magnitude lower at 1900 K. The etching and sublimation kinetics were followed over time as the NPs lost up to ~40% of their initial masses. Sublimation gradually slowed over time, as expected because mass tends to be lost from the least stable surface sites, increasing the average stability of the remaining sites. O2 etching also slowed over time, but N2O etching rates initially increased. This observation indicates that N2O dissociative adsorption can occur at surface sites different from those that dominate the kinetics for O2 dissociative adsorption or sublimation. At long reaction times, the NPs passivated against further N2O attack even at 1800 K, indicating transformation of the surface layer to a structure with few under-coordinated reactive sites.

Published: April 2023

In this work, we explored the ability of N-methyl-S-methyl dithiocarbazate ([H2N-N(CH3)C(=S)SCH3]; DTCZ) to form coordination complexes with copper starting from different copper (II, I) sources. Data proved that the type of used salt affects the stoichiometry and structure of the obtained coordination complexes. Copper complexes of general empirical formula [Cu(DTCZ)Cl2] (1), [Cu(DTCZ)2NO3]NO3 (2), [Cu(DTCZ)2(OH2)]SO4 (3), [Cu(DTCZ)2]PF6 (4), [Cu(DTCZ)(PPh3)2]NO3 (5) and [Cu(DTCZ)2]Br (6) were synthesized in high yield and characterized by elemental analysis, UV-Vis and IR spectroscopy. Molecular structures of 1-6 and also of side- products [Cu(DTCZ)2SO4] (3a), [Cu(DTCZ)2](PF6)(OH) (4b) and [CuBr(C3H7NS2)]n (6a) were determined by single crystal X-ray diffraction (XRD). In all cases, DTCZ binds the metal in the neutral form through the hydrazine nitrogen (NH2) and thione sulphur (S) atom set, forming monosubstituted and disubstituted complexes having tetrahedral, square planar, or square pyramidal geometries, depending on the copper source. In addition, two one-dimensional (1D) coordination polymers and water channels have been observed in the crystal states.

Authors: Krusenbaum Annika , Krause Hinojosa Steffi , Fabig Sven , Becker Valentin , Graetz Sven , Borchardt Lars
Published: April 2023

In this study, we present a matrix of 144 mechanochemically synthesized polymers. All polymers were constructed by the solvent free Friedel Crafts polymerization approach, employing 16 aryl containing monomers and 9 halide containing linkers, which were processed in a high speed ball mill. This Polymer Matrix was utilized to investigate the origin of porosity in Friedel Crafts polymerizations in detail. By examining the physical state, molecular size, geometry, flexibility, and electronic structure of the utilized monomers and linkers, we identified the most important factors influencing the formation of porous polymers. We analyzed the significance of these factors for both monomers and linkers based on the yield and specific surface area of the generated polymers. Our in-depth evaluation serves as a benchmark study for future targeted design of porous polymers by the facile and sustainable concept of mechanochemistry.

In this paper, we proposed rapid laser-induced synthesis of copper micropatterns on the surface of oxide glass from deep eutectic solvents (DESs) consisting of choline chloride, citric or tartaric acid and copper acetate as copper plating solutions. It was shown that upon irradiation with continuous-wave 532-nm laser radiation, it is possible to increase the deposition rate of copper and create micropatterns with a resistance close to the value of pure metal together with high adhesion to the substrate surface. This metallization method is favorable for the practical use of copper patterns, including in production of new printable microelectronic devices. Thus, we demonstrated the possibility of copper deposition on arbitrary three-dimensional surfaces. Moreover, the resulting copper micropatterns were tested as working electrodes for non-enzymatic glucose. Finally, the proposed technology can be successfully used for design and development of sensor platforms for the electrochemical analysis and microelectronic devices

Authors: Rashid Wani Aadil , Kumar Sai , Solomen Subin , TU Jimshad
Published: April 2023

Background Slow breathing especially with prolonged exhalation appears to reduce sympathetic nerve traffic and thus causes arteriolar dilatation. Loaded inspiratory exercise has been demonstrated in studies to lower blood pressure. However the optimal intensity and duration of loaded training to control hypertension is not known. The objective of the present study was to compare the effect of 10 cm loaded inspiratory training with that of 20 cm loaded training in controlling hypertension after third and sixth week.Methodology Thirty subjects with essential hypertension stage I or II were included and randomized into two groups. Group A received inspiratory loaded training with 20 cm of water loaded training and Group B received inspiratory loaded training with 10 cm of water loaded training. Training was performed at home for 30 minutes every day twice daily for 3 weeks. Blood pressure was measured at baseline before the intervention after 3rd and 6th week.Results Both the groups showed statistically significant reduction in blood pressure after six weeks of loaded training plt.0001. However on comparing the groups both the groups were equally effective in reducing blood pressure after 3rd and 6th week of training p values ndash Systolic gt.850 gt.268 Diastolic gt.761gt.304 respectively.Conclusion Loaded training can reduce both systolic and diastolic hypertension after six weeks of training. There was no difference in effectiveness of 10 cm loaded inspiratory training when compared to 20 cm loaded training in controlling hypertension after 3rd and 6th week.

Published: April 2023

Background High body mass index BMI is associated with a decrease in cerebral blood flow volume and an increase in cerebrovascular resistance. According to different studies having a high BMI is correlated with lower regional cerebral blood flow in the pre-frontal cortex of healthy individuals. These findings suggest that having a high BMI is a risk factor for diminished prefrontal brain function and may be reduced executive function. The purpose of this cross-sectional study was to examine the relation between increased BMI and pre-frontal lobe functions in healthy individuals.Method A total of 73 subjects in the age group of 30-45 years were included in this study. The Saint Louis University Mental Status Scale SLUMS was used to examine pre-frontal lobe functioning in 37 males and 36 females in order to establish a connection with elevated BMI. The BMI was measured using Queteletrsquos Index and WHO standards were utilized to determine the state of body composition. The data was analyzed with the SPSS version and p value of less than 0.05 was considered statistically significant.Result A total of 73 people participated in this study with a mean age of 37.86plusmn4.4 years. The study discovered that people with an elevated BMI had poor pre-frontal lobe function which was statistically significant r -0.250.Conclusion According to the findings of this study having a higher BMI can contribute to lower pre-frontal brain function.

La introducción de la imprenta en los archipiélagos ibéricos del Atlántico (Canarias, Madeira, Azores y Cabo Verde)
Authors: Regueira Benítez Luis , Poggio Capote Manuel
Published: April 2023

La imprenta de tipos móviles, inventada alrededor de 1450, ya se había extendido por Europa a principios del siglo XVI. Durante este siglo y el siguiente fue llegando además a algunos enclaves coloniales de América e incluso de Asia. Sin embargo, los archipiélagos ibéricos del Atlántico (Canarias, Madeira, Azores y Cabo Verde) no se beneficiaron de esta invención hasta 1750, y no fue hasta bien avanzado el siglo XIX cuando todos estos territorios insulares pudieron contar con sus propios talleres de imprenta. Este artículo describe la llegada de esta industria a las islas y algunos detalles relevantes de su historia. La comparación entre diferentes lugares de la misma región geográfica contribuye a identificar varios rasgos peculiares.

EVALUATION OF THE 1950 TURKISH GENERAL ELECTIONS IN THE CONTEXT OF SEAT MAXIMIZATION APPROACH
Authors: SEVİNÇ Hüseyin
Published: April 2023

The 1950 elections in Turkey are of significant importance as they represent the first election in which the government changed hands through a democratic process. This study examines the 1950 elections in the context of the seat maximization approach. The study analyzes the decision taken by the ruling party at the time, the Republican People's Party (CHP), regarding the current electoral system, and the situation that arose as a result of the expectations related to this decision. The central argument of this study is that the decisions made by ruling parties to change or maintain the electoral system are shaped by the expectation of increasing their own representation. The study highlights the main issue that decisions taken by ruling parties within the framework of seat maximization may not always correspond with the resulting outcomes. In this study, the seat maximization approach is first introduced, followed by an analysis of the political and social structure of the period. Finally, the demands of political parties regarding the electoral system and the resulting outcomes are evaluated.

Published: April 2023

La celulosa al reaccionar con periodato de sodio se oxida parcialmente produciendo un dialdehído que se conoce en inglés como “hairy cellulose”. Este tipo de celulosa se compone de un cuerpo cristalino, que proporciona resistencia fisicoquímica, y cadenas de celulosa amorfas en los extremos las cuales tienen disposición para ser modificadas químicamente. Una de estas modificaciones se realiza con clorito de sodio el cual oxida selectivamente a aldehídos produciendo el dicarboxilato de celulosa nanocristalina (DCCN), este material con gran carga electrostática se ha empleado principalmente para la extracción de metales y en menor proporción para compuestos orgánicos. Por esta razón, en este trabajo se empleó como sorbente en la preconcentración de ibuprofeno. Se evaluaron diferentes condiciones como pH, concentración inicial, masa del sorbente y la presencia de otros fármacos (naproxeno y diclofenaco). A pH 7 empleando 10 mg del DCCN se logró retener más del 80% del fármaco en solución acuosa y una capacidad máxima de 176.7 mg·g-1.

Published: April 2023

Se lleva a cabo la calibración de una pipeta graduada de 5 mL utilizando dos métodos. De la forma tradicional se obtiene un volumen de calibración de (5.0475 ± 0.0103) mL, mientras que a partir de la regresión el volumen de calibración es de (5.042 ± 0.012) mL. Se compararon estadísticamente los valores con el algoritmo descrito que se encuentra en la bibliografía de Miller y Miller obteniendo que las incertidumbres son estadísticamente iguales entre los dos métodos; sin embargo, el valor de la media no. Dado que el procedimiento propuesto para calibrar el material volumétrico a partir de la regresión lineal presenta menos fuentes de incertidumbres podríamos concluir que el segundo método puede ser más confiable.

Published: April 2023

En este trabajo se presentan los resultados del estudio de recuperación de Au(III) a partir de soluciones de HCl, utilizando como extractante un líquido iónico (LI), el Cyphos IL 101 (cloruro de trihexil(tetradecil)fosfonio) encapsulado con quitosano reticulado con tripolifosfato de sodio (TPF). Se evaluaron diferentes parámetros de fabricación, como la concentración de LI (5-30%) y el tiempo de reticulación (20 min y 24 h). Posteriormente, se evaluó la eficiencia y la velocidad de extracción del Au(III). La reticulación evita la disolución del quitosano en medio ácido, sin embargo, solo fueron estables los materiales con bajas concentraciones de LI (5-10%), en medio HCl 1.0 M. El Au(III) fue eficientemente extraido, como tetracloruro aniónico, mediante un mecanismo de intercambio iónico. La eficiencia de extracción se incrementó con el contenido de LI en las microcápsulas (hasta 72 mg g-1),  sin afectaciones significativas en la velocidad de extracción. El tiempo de reticulación no afectó significativamente la capacidad, ni la velocidad de extracción del Au(III).

Los parámetros termodinámicos determinados son: la constante de equilibrio (β), la energía libre de Gibbs (ΔG°), la entalpía (ΔH°) y la entropía (ΔS°). También se determinó la estequiometría del complejo formado en el sistema. Los resultados obtenidos son: log β=3.520 ± 0.037, ΔG°= −4.810 kcal/mol, ΔH°= (−0.202 ± 0.006) kcal/mol y −TΔS° = −4.610 kcal/mol; la estequiometría obtenida fue 1:1 correspondiente al complejo Mtf (VO)2+.
THE MATHEMATICAL ANALYSIS AND IMPROVEMENT OF MATRIX ALGORITHM FOR FEEDER FAULT LOCATION BASED ON FTU IN THE DISTRIBUTION NETWORK
Authors: Soronga Blaise Kevine Lenz , Zafar Shayan , Shaowu Shi , Benjamin Binda Yumba
Published: April 2023

The mathematical analysis and improvement of matrix algorithm based on FTU has been proposed to solve fault location problem in complex multi-source and multi fault distribution networks of power system. Based on the structural characteristics of the distribution system, a description matrix D is established by assuming the power sources and a positive direction and it derived from the correlation between the positive direction and different power lines. As a function of the fault current direction transmitted by the terminal power supply unit which is our feeder terminal unit (FTU), the fault information vector F is set up. By combining the description matrix D and searching for non-zero elements in the fault information vector, the fault location vector is discovered according to the fault location criteria. During the observation of the elements in the fault location vector, by analyzing we immediately found the location of the defect area. This algorithm can solve problems that cannot be completely solved by other algorithms, such as power terminal failures, ring network failures, and multi-source failures. This method does not require matrix multiplication or normalization. The widespread use of distributed generation (DG) has made the distribution network more complex, and it leads to the failure of the traditional matrix algorithm. Therefore, the matrix algorithm is further improved to adapt the complex characteristics of DG. Considering the accuracy, we avoid random search operations by filtering fault candidate scenarios based on fault confidence and Each algorithm run 100 times in a loop, and the average time taken for a single run is used as a measure of the computational efficiency of the algorithm. The matrix algorithm utilizes the information uploaded by FTU to SCADA to create network description matrix, fault information matrix, which are then used to obtain the fault judgment matrix for fault location and isolation and it proves that the algorithm judgment is effective.

Garimpos Ilegais na Amazônia: como a atividade mineradora impacta o meio ambiente da Volta Grande do Xingu em Altamira-Pará?
Authors:   , Pereira Adonaldo de Sousa
Published: April 2023

A atividade mineradora ilegal praticada no coração da floresta Amazônica tem impactado de maneira irreversível unidades de proteção integral, unidades de uso sustentável, assoreamento e contaminação de rios e lençol freático pelo uso descontrolado de metais pesados – mercúrio - destrói o ecossistema pesqueiro, compromete a atividade dos pescadores nativos, desvia o leito de rios, gera conflitos em territórios de comunidades tradicionais entre garimpeiros e povos tradicionais, causa danos psicossociais na saúde de trabalhadores marginalizados em decorrência de doenças ocupacionais. Não obstante, o Departamento Nacional de Produção Mineral (DNPM), hoje, transformado em Agência Nacional de Mineração (ANM) é a responsável por regular e fiscalizar em todo o território nacional a atividade mineradora, porém, como não há estrutura efetiva de pessoal e equipamento para realizar fiscalização, haja vista o sucateamento dos órgãos de proteção ambiental do Estado brasileiro (IBAMA, ICMBio, etc), a recorrência da prática ilegal de extração de ouro e outros minerais na região é trivial. Nesse sentido, o presente trabalho sobre “Garimpos Ilegais na Amazônia: como a atividade mineradora impacta o meio ambiente da Volta Grande do Xingu em Altamira-Pará?” pretende demonstrar como a atividade mineradora nesses garimpos impactam o meio ambiente, por meio das ações antrópicas e decorrente das incongruências do poder público que desprovido de prioridades, permitem que essas consequências ocorram no ambiente, corroborando para o ecocídio ambiental, etnocídio cultural e o genocídio de povos e comunidades tradicionais que ali vivem, criticar a falta de estudo de impacto ambiental no escopo do requerimento da Agência Nacional de Mineração para se obter a permissão de lavra garimpeira, promoção de políticas públicas na região para desestimular à prática da atividade ilegal, compreendendo a necessidade e respeitando os direitos humanos dos trabalhadores marginalizados que sem perspectiva alguma de acesso de trabalho na cidade, após o término de grandes obras realizadas na região, são em maioria, cooptados por associações criminosas - empresários, madeireiros, políticos e agentes públicos - que financiam a atividade ilegal com maquinários, equipamentos e recursos financeiros.
A ANÁLISE DO CONHECIMENTO EM PLATÃO À LUZ DA METÁFORA DA CAVERNA NO LIVRO VII DA REPÚBLICA
Authors:   , PINHEIRO ALEX GUEDES
Published: April 2023

Este trabalho apresenta a análise do conhecimento em Platão à luz da metáfora da
caverna no livro VII da República. Inicialmente, apresentou-se a concepção de
Estado na República de Platão, onde ele apresenta o conceito de justiça, termo que
circunda todo o Estado e sua obra, assim como também discute o nascimento do
Estado, já que o homem não é um ser isolado, mas necessita dos outros para
atender às suas necessidades. Afirma também quais são as classes existentes no
Estado, desde a superior à inferior. Enfatiza como a poesia, a música e a ginástica
têm papel fundamental na vida do governante, além de sublinhar as virtudes
cardeais essenciais para sua formação. Busca dizer alguns aspectos sobre a
educação das mulheres, que deve ser semelhante à dos homens. Revela como era
a educação dos governantes-filósofos, que deviam cuidar do Estado, assim como o
papel da aritmética e da geometria, que eram conhecimentos necessários para a
educação dos jovens e, por último, como eram distribuídos os Estados corrompidos.
Todos esses fatores foram importantes para a compreensão do Estado no
pensamento platônico. Em seguida, expõe-se a metáfora e a saída da caverna,
como meio para que o homem possa contemplar o real e após abstraí-lo não guarde
inteiramente só para si, mas retorne à caverna buscando convencer os seus que ali
vivem de sua contemplação feita. Assim, conclui-se esse trabalho falando do
conhecimento que advém da recordação de uma vida passada, já que nesta ele
contemplou o conhecimento e, após reencarnar, a sua alma esquece o que foi
apreendido, mas com o tempo ela rememora. Segundo Platão, também o
conhecimento se divide em dois graus; a doxa, que são os conhecimentos provindos
pela opinião e a episteme que é o conhecimento que vem por meio da razão.

Published: April 2023

Las peras var. Beurré D’Anjou son frutos de piel verde, pero frecuentemente presentan una mejilla rojiza o ‘blush’ debido a la exposición solar. Estos frutos son aptos comercialmente y reciben un manejo post-cosecha similar a los de color verde. El objetivo del presente trabajo fue comparar el metabolismo oxidativo y cambios en parámetros de calidad en pera var. Beurré D´Anjou con un sector de piel con ‘blush’ respecto a frutos con piel completamente verde. A cosecha se evaluaron parámetros de calidad de los sectores verde y con blush de frutos expuestos al sol. Sobre la piel se determinó color superficial, contenido de clorofila, antocianinas y estado oxidativo. El sector blush presentó mayor firmeza (67,7 N), contenido de sólidos solubles (13,4 °Brix) y degradación de almidón (38%) y reducción de acidez málica (0,25%) en comparación con el sector verde con 61,9 N, 12,0 °Brix, 26% y 0,47% para cada parámetro, respectivamente. El ángulo HUE° fue 73,9 en el sector blush y 123,9 en el sector verde. Este menor ángulo HUE° expresa el tono rojizo asociado a un marcado incremento del contenido de antocianinas. En el sector blush se determinó un incremento de 59,7% de la peroxidación lipídica y de 55,2% de la capacidad antioxidante respecto al sector verde. Se determinaron diferencias evidentes en los parámetros de calidad y el estado oxidativo del sector con blush en comparación al verde, independientemente de que ambos se hayan desarrollados en similar condición de exposición solar.
DIGESTIBILITY OF ADDITIONAL CRUDE PROTEIN FROM TROPICAL LEGUMES IN MIXED GRASS-LEGUME RATIONS FOR RUMINANTS
Authors: Castro Montoya Joaquín Miguel , Albarrán-Portillo Benito
Published: April 2023

The digestibility of crude protein (CP) from tropical legumes in grass-legume mixed diets was studied based on literature data by regressing the digestible CP (digCP) on the proportion of CP from legumes in the diet. In vivo studies reporting on CP concentration and in vivo CP digestibility values of ruminants fed diets with tropical legumes and grasses with no other feed, were selected for the analysis (56 publications, 213 dietary treatments (150 legume forages, 63 grasses)). First, observations were classified into categories based on the CP concentration of the control grass using the first and the third quartile of the grass CP concentration (LOW, MEDIUM, and HIGH grass quality). Second, legumes were divided based on their growth habit: herbs, shrubs, and trees. Based on the slopes and coefficients of the regressions of the digCP supply on the proportion of CP from legumes, CP digestibility of legumes was higher than that of LOW quality grasses, but lower than that of MEDIUM and HIGH quality grasses. Furthermore, the digestibility of the additional CP from legumes was higher when combined with MEDIUM quality grasses (0.493) compared with those of LOW quality (0.432), while it decreased when combined with HIGH quality grasses (0.305). No differences appeared in the digestibility of additional CP from legumes depending on their growth habit (range 0.415 to 0.421). These results can help optimize the assimilation of CP supplemented by tropical legumes.
An Analysis of Student Learning Style in Learning English in Sekolah Indonesia Kuala Lumpur, Malaysia
Authors: Hardiyanto Asep
Published: April 2023

Learning style is one way to find out a person's most comfortable way in the learning process being carried out. In the learning process takes place, students have their learning style preferences. Learning styles have four preference models, namely VARK; visual, aural, read/write, and kinesthetic. The VARK can help students' learning style preferences in maximizing their learning style. Thus, the gap in this research is the investigation of learning styles in the English as a Second Language (ESL) context. The purposes of this study were to find out; (1) the learning styles employed by students and (2) the dominant learning style employed by the students in Sekolah Indonesia Kuala Lumpur, Malaysia in learning English. This research used a descriptive quantitative research method that deals with the types of learning styles by VARK Neil Fleming. The total participants of the research were 28 students. The findings showed that (1) it was found that in the ESL context, students prefer to use two learning style preferences, namely; unimodal and bimodal, and (2) students predominantly used the kinesthetic learning style. The current findings implied that ESL teachers should provide English learning activities which is able to trigger students to engage directly in the process of teaching and learning in the classroom so that they can use their learning style maximally. Furthermore, the teaching process should emphasize on students—centered learning in order that students will be easier in reaching the objectives of Learning English in ESL context.

Due to the variety of neurological abnormalities that these patients experience, the neuro-oncological population effectively conveys the complexity of neurological disability. Also, because of treatment advancements, patients with brain tumors live longer and need rehabilitation services. Even if their importance in this environment is acknowledged and their role is growing, the nurse's position in the interdisciplinary specialty of neurorehabilitation is not precisely defined. The study aims to determine the fundamental skills that neurorehabilitation nurses should possess, which might be taught in a specialty course. According to the literature, advancing medical professionals' scientific and practical knowledge is necessary for the growth of rehabilitation. This organized training curriculum could be included in graduate nurse continuing education programs and undergraduate nursing education programs. For nurses to provide better overall care and care management for patients with extremely complex disabilities, such as those affected by brain tumors, they must become experts in neuro-rehabilitation. The next step will be to begin debating the creation of a specialization program in neurorehabilitation nursing at the level of scientific associations related to neurorehabilitation and cancer.

Published: April 2023

The use of medical cannabis for therapeutic treatment of various medical conditions has gained popularity due to its pain-relieving, anti-inflammatory, and sleep-improving properties. In greenhouse and closed buildings cultivation, optimizing water and nutrient management is essential for achieving maximum yield and quality. Water quality used for irrigation is critical for cannabis plant growth and yield, as it affects mineral uptake. This study assesses the impact of an ecological water regenerator system, based on physical and electromagnetic principles, on the growth and quality of medical cannabis cultivated in a greenhouse. These techniques restore water quality to its optimal state, promoting optimal hydration and nutrition of medical cannabis plants. The results show that using the ecological water regenerator system significantly enhances mineral uptake and growth stimulation, improving water and nutrient management and enabling the supply of an optimal amount of water and nutrients to the plants. Consequently, this approach promotes vigorous and productive growth, indicating that incorporating an ecological water regenerator is an effective approach for optimizing and enhancing medicinal cannabis cultivation. Compared to bulk water, using regenerated water significantly improves cannabis plant growth, flower biomass, and THC levels while reducing water and fertilizer usage. This innovative system can achieve new standards of quality and performance in the sustainable cultivation of medical cannabis.
