Empty fruit bunch (EFB) is a promising materials to produce activated carbon for electrode materials applications in an energy storage device due to its low cost, high availability and porosity. EFB will require further processing to convert it into activated carbon to enhance its electrochemical performance. In this research, a two-step activation was utilized, in which EFB undergone pyrolysis at 500 °C before being activated via chemical and physical activation methods under various conditions to produce activated carbon. The samples were then characterized using weight loss analysis, Field Emission Scanning Electron Microscopy with Energy Dispersive Xray Spectroscopy (FESEM-EDX) and Raman Spectroscopy to evaluate their physical characteristics. Cyclic voltammetry (CV), galvanostatic charge discharge (GCD) and electrochemical impedance spectroscopy (EIS) were performed to evaluate their electrochemical performance. The specific capacitance measured from CV analysis shows better performance for samples from physical activation which were in the range of 24 to 140 F/g compared to samples from chemical activation that resulted in only 36 to 90 F/g. These results suggested that physical activation has yielded better electrochemical performance of activated carbon which was influenced by the higher activation temperature in comparison with that of the chemical activation that was performed at lower activation temperature.

Gait analysis is a vital field in biomechanics, focusing on studying human walking patterns and movement. Traditional methods relied on visual observation, lacking accuracy and objectivity. Instrumented gait analysis improved measurements using specialized equipment like motion capture systems and wearable sensors, but had limitations due to cost, and markers or sensors interfering with natural movement. The field underwent a significant transformation with the advent of markerless pose estimation-based gait analysis, which harnessed computer vision methodologies to monitor human movement without the requirement for specialized equipment, delivering a cost-effective and easily accessible analysis in real-world environments. However, it still faces challenges, including limitations in the sagittal plane and reliance on computationally demanding models like OpenPose. This study introduced a novel frontal plane gait analysis approach using the lightweight MediaPipe Pose model and a single camera setup. The objective is to evaluate the feasibility, and accuracy of MediaPipe Pose by comparing it to the established 3D Vicon motion capture system. The proposed approach tracked body keypoints during gait, detected gait events based on ankle depth changes and vertical difference between left and right ankles, and calculated gait parameters. The findings demonstrated that MediaPipe Pose-based gait analysis showed promise for accurately analyzing gait parameters in the frontal plane with low mean absolute error (0.00–0.30). Combining this method with satellite technology enhances e-health by facilitating teleconsultations, remote diagnostics, and extending healthcare services to disaster-stricken or remote areas.

Alzheimer’s disease, acknowledged for its intricate and degenerative characteristics, presents considerable challenges, particularly among the elderly population. The relentless nature of Alzheimer’s, marked by the gradual deterioration of cognitive function, underscores the urgency to develop effective strategies for early diagnosis and intervention. Artificial intelligence has played a significant role in terms of disease diagnosis and treatments. However, it has got limited acceptance in the medical community due to its lack of transparency. This study aims to advance the understanding and prediction of Alzheimer’s disease progression through the integration of time-aware modeling and Explainable AI techniques. It makes significant contributions by addressing two key objectives in the context of Alzheimer’s disease. First, by including temporal aspects, it accurately depicts the pace at which relevant predictors change over time, thereby capturing the dynamic nature of Alzheimer’s disease. Second, by giving interpretable insights into the algorithm’s decision-making process, the study hopes to empower researchers and physicians. This approach not only enhances transparency but also builds trust in the model’s outcomes. The ADNI dataset, comprising 2980 observations, was employed for developing a prediction model using various machine learning classifiers. Among these classifiers, the Random Forest model emerged as the top performer, exhibiting superior accuracy, a high Coefficient of Determination (R2), and an impressive F1 score. To enhance interpretability, subsequent analyses utilized LIME and SHAP techniques. By combining time-aware modeling with Explainable AI methods, we seek to unravel the dynamic relationships within the dataset, providing transparent insights into the temporal evolution of Alzheimer’s disease. Thus, this paper contributes to the creation of a clinically relevant and practical model for monitoring Alzheimer’s disease progression that holds the potential for a deeper understanding of the evolving nature of the disease and paving the way for personalized and timely interventions.
Legal Nature of the Central Executive Committee of the USSR under the Constitution of the USSR of 1924
Authors: Sharapov R. D.
Published: July 2024

The paper provides a comprehensive analysis of the role and status of the Central Executive Committee of the USSR (CEC of the USSR) in the context of the dynamic constitutional, legal and institutional development of the Soviet Union. The author provides the reader with a deep dive into the essence of the CEC of the USSR, providing a brief but meaningful historiographical description of the collective body of state power. The main attention is paid to a detailed analysis of the status of the CEC of the USSR before and after the adoption of the Constitution of the USSR in 1924, to identify and highlight key diﬀerences in its structure and functioning due to innovations introduced with the adoption of this legislative act. The paper examines the key areas of activity of the Central Executive Committee of the USSR in detail both in the period before the adoption of the Constitution (1922–1925) and in the post‑constitutional period (1925–1938), forming a categorical layer of the problematic issue. The paper highlights and explains the stable position of the CEC of the USSR in the political sphere of the USSR and gives a brief assessment of its activities and development. The paper is of interest to researchers of the history and law of the Soviet period and is an important contribution to understanding the organizational and regulatory aspects of the functioning of the CEC of the USSR in the broad context of constitutional construction in the ﬁrst decades of Soviet history. The main emphasis is placed on the formation of a comprehensive framework for the perception of the CEC of the USSR as a body that is simultaneously characterized by isolation in the system of state bodies of Soviet power and close connection with other such bodies. Such an emphasis allows the reader to form a wide categorical and conceptual spectrum of opinions & sententiae on the problem of deﬁning and analyzing the legal nature of the CEC of the USSR, which is important for Russian historiography.
The Forensic Service (the Case Study of the Sverdlovsk Region in the 1920s–1940s)
Authors: Antropov A. V. , Shamsumova E. F.
Published: July 2024

The paper describes the process of formation and functioning of a specialized forensic service in the Urals in order to successfully combat crime during a diﬃ-cult unstable transition period for the country. The authors put museum information resources and archival documents as the substantive foundation of the paper. It is emphasized that the formation of the service begins with the relocation of specialists who organize this work to Sverdlovsk from Ufa. It is noted that in the 1920s there was an urgent need for personnel training for this type of activity, in connection with which courses for the training of forensic and technical experts at the Criminal Investigation Department of the NKVD were actively developing. Attention is focused on the importance of the issue of methodological support. In the 1920s the ﬁrst textbook on forensic expertise appeared in Russia. During the study period, along with the need to work with traditional traces found at the scene, there was a need to detect and remove traces and objects during research that required the use of physico‑chemical methods in laboratories, in connection with which physicists and chemical experts appeared. Thus, the use of special research methods for objects seized from accident sites began in the late 1920s. In their conclusions, the authors note that the formation of an expert forensic service was carried out on the basis of scientiﬁc justiﬁcation and methodological support of methods to combat unsolved crimes.

Authors: Mantoo Azmat J. , Jahan Azmat , Younus Zohra , Hamid Umer
Published: July 2024

Background: Gestational diabetes mellitus (GDM) is a common metabolic disorder among pregnant women. It is important to be diagnosed and treated early to minimize complications for both the mother and the foetus. Recent studies found that deficiency of vitamin D is a risk factor for GDM and its supplementation may be helpful in prevention of GDM. Objectives were to assess vitamin D status in pregnant women with or without GDM and to find out the association between vitamin D deficiency and GDM.
Methods: A total of 400 patients were included in the study, 200 pregnant women diagnosed with GDM and 200 normoglycemic pregnant women. Serum 25 (OH) vitamin D concentration in these women were compared.
Results: Only 6.75% of women were found to have normal vitamin D levels, all others having either insufficiency 18.5% or deficiency 74.75%. In case group around 79% of women had vitamin D deficiency, 70.5% in control group. In case group around 14.5% of women had vitamin D insufficiency, 22.5% in control group. In both case and control group around 6.5% and 7% of women were within the normal range respectively. Mean vitamin D is 14.3 ng/ml in case group and 15.4 ng/ml in control group.
Conclusion: Prevalence of vitamin D deficiency is alarmingly high in pregnant women in India and has become a re-emerging public health issue and needs to be addressed.

A study on role of vitamin D3 in uterine fibroids
Authors: Moshika  , Sailatha
Published: July 2024

Background: Fibroids are one of the significant non-cancerous growths prevalent in females. Vitamin D is found to have a significant influence in the development of fibroid by suppressing the formation of an impaired extracellular matrix (ECM) due to the abnormal reaction to tissue damage response by regulating it. The study is done to find out the mean vitamin D3 levels among women with fibroids and without fibroids, respectively.
Methods: This study was a hospital based analytical study done in the department of obstetrics and gynaecology, Chettinad Hospital and Research Institute, Chennai, India for a period of 18 months. Two groups of 60 each, one group with fibroids and the other without fibroids were recruited. Venous blood was drawn from both groups using venipuncture technique and the serum vitamin D3 levels were estimated and compared.
Results: The mean vitamin D3 level was 12.98±7.79 ng/ml for those with fibroids and 44.50±9.60 ng/ml for normal group. The mean value was significantly lesser among those with fibroids than those normal with p value of less than 0.05. The mean vitamin D3 levels were similar between various sizes of fibroids.
Conclusions: In this study, the level of vitamin D3 was significantly lower among those with fibroids than those women who did not had any fibroids which shows that normal vitamin D3 levels might be protective against uterine fibroids and vitamin D deficiency can lead to the development of fibroids.

Published: July 2024

Background: Use of inappropriate family planning (FP) methods is one of the major reasons for population growth in India. If the determinants of FP methods were understood, it would help to improve the acceptance of the FP methods among the users and thus contribute to a stable population. The study was conducted to assess the unmet need for contraception and its determinants among married women of reproductive age (WRA) group in the slums of Burdwan municipality.
Methods: A community based descriptive and cross-sectional study conducted among 330 married WRA in the slums of Burdwan municipality, West Bengal, from November, 2022 to January, 2023. Fifteen slums were selected from 144 slums in the municipality, by simple random sampling (SRS) and from each slum, study subjects were selected by SRS, from a list of married WRA. A pre-designed, pre-tested, semi-structured schedule was used for data collection and data analyse using SPSS-23.
Results: Around 51% couples used some methods of FP and 49% did not use any methods. Among non-users, the unmet need was 18.2% for spacing and 15.1% for limiting births. Significant association (p<0.05) among the determinants of FP, was observed with educational status of respondents and age at marriage.
Conclusions: Age, education, socio-economic status, age at marriage, age at 1st pregnancy, types and adverse effects of contraception are important determinants both FP methods and unmet need. So proper counselling and assessment of WRA is essential.

Authors: Sharma Sakshi Pramod , Wakode Shamrao Ramji
Published: July 2024

Vaginal birth after caesarean section (VBAC) is an appropriate solution to decrease the caesarean section rates and also to minimise the morbidities and complications due to repeat caesarean sections. Though trial for vaginal birth, that too after two or more caesarean sections is challenging, it will certainly help in reducing caesarean rates worldwide if tackled by proper decision making and vigilant observation. Present study is intended to review the research publications surrounding VBAC-2. Search was carried out for gathering research publications up to April 2024 by using the keywords of "Vaginal birth after two or more caesarean sections", "trial of labour after two or more caesarean section", "VBAC-2", or "TOLAC-2". 51 relevant publications were considered in present study. Success rates of VBAC-2 studies were calculated as 70.83% for the study population. Furthermore, uterine rupture, blood transfusion, hysterectomy, maternal and neonatal outcomes were analysed after VBAC-2. Besides these, 14 case studies were analysed separately. Results indicate that VBAC-2 is safe, but careful patient selection and vigilant monitoring of indications is necessary for decision making. Information gathered and analysed will help in making evidence centred decisions in such cases.

Published: July 2024

Background: An incisional hernia is characterized as any defect in the abdominal wall, with or without a noticeable bulge, in the region of a postoperative scar, identifiable through clinical examination or imaging. This condition can be detected through clinical examination or imaging and affects approximately 10-20% of patients who undergo abdominal operations. Aims and objectives of the study was to evaluate various precipitating factors, clinical presentations, management and post-operative complications in patients with incisional hernia.
Methods: A retrospective study of 150 patients conducted at a tertiary care teaching hospital.
Results: In this study, incisional hernia was more common in obese, elderly, and female patients. The incidence was higher with Pfannenstiel incision followed by lower midline incisions. Incisional hernia was common between 1-5 years of index surgery and it was observed that more the risk factors and complications associated with index surgery, earlier was the onset of incisional hernia. Patients had a defect of size <4x4 cm were 58.66%. Open onlay mesh repair was done in 36.66% patients, preperitoneal mesh repair in 13.33%, retro rectus mesh repair in 13.33%, laparoscopic mesh repair in 28.66% and anatomical repair alone in 7.99% patients. Duration of laparoscopic surgery was longer compared to open. Most common post- operative complication was seroma (4.66%) followed by wound infection (2.66%).
Conclusions: Incisional hernias occur more in females as they commonly undergo lower abdominal surgeries. Subcutaneous suction drain decreased the incidence of post-operative wound complications.

Case report of rare cause of small bowel obstruction: distal migration of metal biliary stent requiring enterotomy
Authors: Rumble William T. , Lonie James M. , Donovan Michael , Kia Chris
Published: July 2024

Endoscopic biliary stent placement is a mainstay in the management of biliary strictures both malignant and benign. Distal stent migration is a known complication of metal biliary stents, however small bowel obstruction or perforation are rare. In this report from a tertiary referral centre, we detail a mid-small bowel obstruction caused by covered metal stent migration requiring a laparotomy and enterotomy for definitive management. A 69-year-old male was admitted to the Sunshine Coast University Hospital with obstructive jaundice on a background of previous metal biliary stent placement. On day 3 of his admission, he developed worsening abdominal pain. Cross-sectional imaging demonstrated distal migration of his stent to his mid-jejunum, causing a high-grade small bowel obstruction. He underwent laparotomy to retrieve the stent. He recovered well and underwent a percutaneous transhepatic cholangiogram with stent replacement. In this case, distal biliary stent migration causes a small bowel obstruction. Whilst uncommon, risk factors including previous intra-abdominal operation can be used to identify patients unlikely to achieve successful expectant management of distal migration.

Published: July 2024

Intussusception of the bowel is defined as the telescoping of a proximal segment of the gastrointestinal tract within the lumen of the adjacent segment. This condition is frequent in children and presents with the classic triad of cramping abdominal pain, bloody diarrhea and a palpable tender mass. Secondary intussusception is caused by organic lesions, such as Meckel’s diverticulum, benign and malignant lesions, metastatic neoplasms or sometimes iatrogenically. Surgery is the definitive treatment of secondary intussusception. Formal bowel resection with oncological principles is followed for every case where a malignancy is suspected. A ten-year-old female presented to the casualty with severe pain in abdomen associated with 1 episode of blood in stools diagnosed with intussusception. She was taken for emergency laparotomy, and no lead point was identified. She presented with recurrent intussusception and was taken for re-exploration, when a definitive approach was opted for, and she underwent a resection of the obstructed bowel at the ileo-caecal junction and an ileo-ascending anastomosis. On histopathology, the ileo-caecal junction showed a proliferative, circumferential mass which was confirmed to be a diffuse large B cell lymphoma. It is uncommon for pediatric intussusception to result from a neoplasm. It takes imaging modalities to make the diagnosis. Surgical intervention is required as soon as a suspicion is raised in order to avoid consequences such gut necrosis and ischemia.

Published: July 2024

The abdominal aortic aneurysm (AAA), representing 70% to 90% of all aortic aneurysms, is characterized by a widening of the diameter due to an irreversible weakening of the vascular walls. Risk factors include advanced age, male sex, smoking, hypertension, atherosclerosis, and genetic predisposition. From a pathophysiological point of view, AAA involves alterations in connective tissue proteins, chronic inflammation with the release of cytokines and matrix metalloproteinases, as well as changes in the extracellular matrix. MicroRNAs (miRNAs) have emerged as promising biomarkers and therapeutic targets in the regulation of gene expression and different specific signaling pathways in vascular pathologies. Among which some miRNAs have been highlighted such as: miR-29 and miR-27b-3p, involved in the degradation of the extracellular matrix and inflammatory processes during the progression of AAA. Some diagnostic methods such as computed tomography play a fundamental role, while some innovative therapeutic strategies, such as the inhibition of miRNAs, represent a leading role as possible diagnostic and therapeutic targets. A comprehensive approach includes surveillance and surgical treatment strategies to mitigate the progression and risk of AAA rupture, thus highlighting the relevance of miRNAs in the diagnosis and treatment of this pathology.

Se presentan datos relativos a la ecología y el comportamiento de Crocodylus intermedius en los ríos Cravo Norte, Ele, Lipa, Casanare y el Caño Matepalma. Se establecen diferencias en el comportamiento de los adultos y el cuidado del nido y de las crías. El período de nidificación ocurre desde finales de diciembre hasta mediados de enero. Las crías nacieron entre mediados de marzo a principios de abril. El tamaño de las nidadas fue de 20 a 34 huevos. Se ubicaron 7 zonas de nidificación. Nidos abiertos después del nacimiento de las crías permiten presumir que las hembras excavan los nidos al momento del nacimiento. La zona de estudio presenta aspectos bióticos y abióticos óptimos; sin embargo, sus pobladores constituyen un factor de enorme presión.
¿EXISTE SODIROA?
Authors: Betancur Julio , Miranda-Esquivel Daniel Rafael
Published: July 2024

Sodiroa s. I es un grupo de especies considerado actualmente dentro de Guzmania (Bromeliaceae). Está formado por los complejos Massangea y Sodiroa s.s., los cuales fueron considerados como géneros independientes en el pasado. Se somete a prueba la monofilia de los grupos y la relación de parentesco entre ellos. Para el análisis se construyó una matriz con 25 caracteres morfológicos y 16 taxones: 12 como grupo interno (7 Sodiroa s.s. y 5 Massangea) y 4 como grupo externo. Los caracteres fueron analizados con pesos iguales, sucesivos e implicados. En todos los análisis Sodiroa s.s. y s. I aparecen como grupos monofiléticos, mientras que Massangea no es un grupo natural. Se propone que Sodiroa s. I. podría reestablecerse como género.
MONOCOTILEDONEAS Y DICOTILEDONEAS: UN SISTEMA DE CLASIFICACIÓN QUE ACABA CON EL SIGLO
Authors: González Favio
Published: July 2024

Se revisa la clasificación de las angiospermas en monocotiledóneas y dicotiledóneas. Nuevos análisis filogenéticos señalan que mientras que las monocotiledóneas son monofiléticas, las dicotiledóneas no lo son, con lo cual se cuestionan de manera fundamental los sistemas de clasificación más empleados actualmente, y se comprueba que la filogenia de las angiospermas basales es incierta. La posible relación cercana entre las Aristolochiaceae y las monocotiledóneas es ilustrada y se usa tal relación como una antítesis a los límites tradicionales entre mono y dicotiledóneas.
ALGUNAS OBSERVACIONES ACERCA DE LA GEOLOGIA DEL SUDOESTE DEL CAQUETA
Authors: Galvis V. Jaime , Pinto R Hernando
Published: July 2024

En el área comprendida entre Florencia y el Caserío de Fragüita en el sudoeste del Departamento del Caquetá. se presenta una secuencia litológica totalmente diferente de la del Alto Magdalena. evidenciándose eventos geológicos completamente disímiles. En el sudoeste del Caquetá hubo episodios de magmatismo no registrados en la literatura geológica de Colombia. Además, se presentan dentro del Caquetá numerosas fallas direccionales, las cuales colocan en contacto fajas de territorio, cuyas unidades estratigráficas presentan notables contrastes. Por otro lado, cabe anotar una gradual disminución de unidades litológicas Fanerozoicas hacia el Oriente.
TODOS LOS CAMINOS CONDUCEN A PAUL ERDÓS
Authors: De Castro Rodrigo , Grossman Jerrold W.
Published: July 2024

La noción de número de Erdös ha estado presente en la comunidad matemática por más de treinta años como una manera de cuantificar el hecho de que la investigación científica se ha convertido durante el siglo XX en un proceso colaborativo, no siendo ya simplemente una activi­dad realizada por individuos aislados. En este artículo exploramos algunos caminos de colabora­ción (relativamente cortos) que pueden seguirse desde Paul Erdös hasta investigadores dentro y fuera de las matemáticas. En particular, hemos determinado que todos los ganadores de la Meda­lla Fields, hasta el año 1998, tienen un número de Erdös menor que 6 y que más de 60 premios Nobel de física, química, economía o medicina tienen un número de Erdös número que 9.

Chase, Lappagopsis (Steud.) Chase y Senescentia D. Giraldo-Cañas. Se comentan las ca­racterísticas micromorfológicas de su antecio superior sobre la base de microfotografías MEB. Sus relaciones morfológicas y anatómicas son discutidas. Se presentan claves para separar las secciones y las especies afines de A. senescens.
Autoeficacia en pacientes programados para cirugía de reemplazo de rodilla: ensayo clínico controlado
Authors: Medina-Garzón Mauricio , Navarro-Córdoba Jefferson Rosendo
Published: July 2024

Introducción: la cirugía de reemplazo de rodilla genera en los pacientes estados de ansiedad, miedo y preocupación. Así mismo, conductas adaptativas antes y después de la intervención quirúrgica que limitan su capacidad de afrontamiento y autoeficacia, además de afectar su recuperación posquirúrgica. Es importante fortalecer la autoeficacia mediante la educación preoperatoria con el apoyo del grupo interdisciplinar. Objetivo: determinar la efectividad de una intervención de enfermería sobre la autoeficacia en pacientes programados para cirugía de reemplazo articular de rodilla. Metodología: ensayo clínico controlado aleatorizado. En una muestra de 75 pacientes programados para cirugía de reemplazo articular de rodilla, asignados aleatoriamente a un grupo control y experimental. El grupo experimental recibió una intervención educativa de tipo interdisciplinaria para fortalecer la autoeficacia en el postoperatorio. Esta intervención consistió en 10 sesiones presenciales de 30 minutos durante 6 meses y el grupo control recibió la información ofrecida en la consulta preoperatoria. Posteriormente, se aplicó la escala general de autoeficacia en el preoperatorio y postoperatorio en ambos grupos. Resultados: se encontró una diferencia estadísticamente significativa de la autoeficacia con la intervención educativa con respecto al grupo control con un valor P de 0,002. Conclusión: la intervención de enfermería tiene un efecto significativo a nivel de la autoeficacia en personas con cirugía de reemplazo articular de rodilla, a partir de la educación preoperatoria y el apoyo interdisciplinar, facilitando su proceso de recuperación posquirúrgica.

Knowledge of Politics: Conceptual Synthesis of Folk Psychology, Political Science and Political Philosophy (About the Idea of ​​Political Conceptology by V.P. Makarenko)
Authors: Chukin S.G.
Published: July 2024

The article examines the idea of ​​political conceptology proposed by V.P. Makarenko and implemented by him in relation to current political problems. The author considers it the answer to the question of what knowledge about politics can be, bridging the gap between normative and descriptive knowledge of political phenomena. As a form of political knowledge, conceptology is a synthesis of ordinary views on politics, political philosophy and political science. It significantly weakens restrictions on language and style, allows for value judgments, a mixture of scientific and journalistic approaches, and the use of artistic images, which allows for maximum individualization of the objects under consideration. Content flexibility of concepts (as V.P. Makarenko understands and uses them) makes them a valuable methodological tool in social cognition.
Legal Decision: The Concept and Functions
Authors: Zykova Svetlana V. ,   Associate Professor of the Department of Theory of State and Law of the Kikot Moscow University, Kulik Oleg V. ,   Associate Professor of the Department of Theory of State and Law of the Kikot Moscow University
Published: July 2024

The article is devoted to the substantiation of the fact that the understanding of legal decisions as acts emanating from state-power subjects, creating legal norms or specifying the content of the rights and obligations of participants in legal relations, is unjustifiably narrow. It is proposed to consider a legal decision as a means of presenting legal requirements that reflect the subject’s ideas about fair and expedient, expressing his legal choice and justified by a reference to generally binding legal imperatives or his own subjective law. The author pays special attention to the analysis of the signs of legal decisions and their functions.

Mejoramiento de caracteres de importancia agronómica en melón criollo (Cucumis melo L.) variedad dudaim mediante selección y recombinación
Authors: Espinosa Carrillo José Francisco , Arreaga Álvarez Jesús Jackeline
Published: July 2024

El cultivo del melón criollo de bolsillo (Cucumis melo L.) ha recibido escasa atención en la investigación agronómica, pese a su potencial productivo y su destacable diversidad fenotípica. Sus frutos presentan diferencias fenológicas, morfológicas y organolépticas que ofrecen oportunidad para el mejoramiento genético de la variedad criolla, el cual es necesario debido a que presenta rendimientos inferiores a otras variedades e híbridos importados. Con el fin de evaluar el potencial de una población seleccionada en el mejoramiento de caracteres de importancia agronómica, en el cantón Palenque, Ecuador, se evaluaron individuos recombinantes de una población seleccionada (Ps) frente a individuos de la población original (Po) de la variedad Dudaim, bajo un diseño de bloques completos al azar con dos tratamientos y tres repeticiones en dos localidades distintas. De acuerdo con las comparaciones estadísticas, la población seleccionada mostró valores promedios significativamente superiores a los de la población original (p=0,05) en 7 de los 10 caracteres de fruto evaluados, presentando alta variabilidad genética y alta heredabilidad en sentido amplio para los caracteres relacionados con la calidad de fruto. Los estudios permiten concluir que existe un alto potencial para alcanzar ganancias genéticas por selección, especialmente para caracteres peso del fruto, sólidos solubles totales y rendimiento por hectárea.
