Published: October 2022

Mapping and analysis of agricultural land is essential for developing strategies for regional land use. Official statistics do not always accurately reflect the quantitative and qualitative indicators of municipal land use structures. Geoinformation mapping methods based on Earth remote sensing data make it possible to most accurately determine the economic structure of a territory. Modern research on this topic has advanced enough to ensure high accuracy of mapping, but such data are not suitable for monitoring purposes. The purpose of this work is to map agricultural land (cultivated fields, fallows, hayfields) on the territory of the Novoanninsky district of the Volgograd region. The article sequentially describes the stages of mapping: initial data, the process of mapping, selection features. A mapping technique based on the use of ultra-high spatial resolution data with verification using high-resolution data is described in detail. An analysis of the main sown areas in the district according to the data of the Federal State Statistics Service (FSGS) was compiled. The increased accuracy of the data obtained corresponds to the goals and objectives of the State Program Effective involvement in the circulation of agricultural land and the development of the reclamation complex. Based on the described methodology, more than 2,500 spatial objects with a total area of more than 215,000 hectares were mapped in the study area. Actual sown area data was compared with official figures. A significant difference of 26.4% was found. The statistics are greatly underestimated. Presumably, this is due to the peculiarities of maintaining statistics, cadastral registration, as well as the concealment of actual data by land users themselves.

Biologically active substances (BAS) contained in medicinal plants are used in the manufacture of medicines, and, accordingly, have certain properties, such as, for example, antioxidant, anti-inflammatory effect, bacteriostatic, bactericidal, the ability to increase the body’s resistance to genotoxicants, etc. Infusions of medicinal plants Oregano (Origanum vulgare) and Greater celandine (Chelidonium majus), selected in their places of growth: in the mountains of Nozhai-Yurtovsky (1090 m above sea level) and Shatoisky (1200 m above sea level) areas of the Chechen Republic, traditionally used for medicinal purposes, were studied for the induction of oxidative stress on strains of luminescent bacteria E. coli. Artificially created Escherichia coli MG1655 biosensor strains containing specially designed plasmids of the pBR322 variant carrying the Photorhabdus luminescens bacterium luxCDABE operon placed under an inducible promoter activated only when certain chemical agents appear in the medium were used in the work. E. coli strains with hybrid plasmids: pSoxS-lux or pKatG-lux were used for detection of substances causing oxidative stress in cells, and with hybrid plasmids: pColD-lux or pRecA-lux for detection of genotoxic substances. It was found that the studied medicinal infusions can have a synergistic effect in combination with the genotoxic drug dioxidine and the oxidant hydrogen peroxide. At the same time, they can act both as an antioxidant and as an antigenotoxicant, depending on the concentration. The concentrations of infusions of Origanum vulgare and Chelidonium majus at the concentration of Greater Celandine – 6 g (CN2) and 3 g (CN3) caused oxidative stress. All other concentrations of Origanum vulgaris and Celandine greater on all bioluminescent strains of E. coli had a slight bactericidal effect. Further studies of biologically active substances of medicinal plants will make it possible to propose them as a protective barrier to the genotoxic, mutagenic or toxic effects of various environmental pollutants
The Classification of Intense Geoecological Situations and Their Landscape Conditionality (by the Example of the Volgograd Region)
Authors:   Volgograd State University, Ryabinina Natalia
Published: October 2022

Currently, the geoecological situation is the main structural unit in the comprehensive study of modern problems of nature management and the main subject of environmental mapping at any spatial level. Each geoecological situation is formed within a specific geosystem and depends on its properties, structure, dynamics, functioning, it also has specific time characteristics. The methodological basis is the geosystem concept, the doctrine of modern landscapes as natural-anthropogenic geosystems. The classification of geoecological situations is carried out by a set of signs, by a set of problems, by the type of anthropogenic impacts and their depth, by leading factors of formation, by the scale of manifestation, by the time of existence, etc. The determination of the severity of the geoecological situation depends on the regional characteristics and specifics of the leading problems and can be considered separately or from the point of view of the living conditions of the population and its state of health or from the point of view of the state of natural resources, geographical components, the preservation of natural geosystems, the uniqueness of landscapes and the gene pool of living organisms. When determining the severity of the environmental situation, an ecocentric (geocentric) integrated approach was used. It allows you to objectively assess the situation in terms of the state and degree of change in geosystems. As a result of the research, it was established that about 63 % of the territory of the Volgograd region is characterized by a conflict and tense geoecological situation. A satisfactory geoecological situation is observed in western areas characterized by the best bioclimatic indicators, the lowest population density, and the level of anthropogenic load. A tense and critical geoecological situation is typical for areas where mining enterprises, large industrial centers are located, as well as for areas that are characterized by a low level of environmental stability of natural geosystems

ABSTRACT Objective To determine the level of association between depressive symptoms and cognitive abilities of institutionalized older adults. Methods This is a cross-sectional study that enrolled 69 older adults, living in a long-term care facility. Investigation of depressive symptoms in all individuals was performed using the geriatric depression scale. Cognitive verbal fluency, digit span forward (DSF) and backward (DSB) tests, and two-minute stationary gait, sit-to-stand test, and six-minute walk test were performed to assess their association with depressive symptoms. Results Depressive symptoms were identified in 35 individuals. Worse cognition and physical performances were associated with the presence of depressive symptoms – Mini-Mental State Examination [t (61) = 2.36; p < 0.05] and Stationary gait test of two minutes [t (53) = 3.12; p < 0.05]. Short-term memory and working memory tests presented worse results in individuals with depressive symptoms (DSF: U = 402.00; p < 0.05 e DSB: U = 341,00; p < 0.05). Older adults with scores below normal in DSF were 5 times more likely to exhibit depressive symptoms. Conclusion The importance of physical, cognitive and social intervention strategies in long-term care facilities for the older adults is highlighted, in order to privilege autonomy. Notably, there is an association between deficits in short-term memory and the presence of depressive symptoms in older adults. Therefore, prospective studies are suggested to investigate the cause-effect relationship of this association with the institutionalization of older adults.

Published: October 2022

O objetivo deste estudo é investigar se há associação entre as Regiões Ampliadas de Saúde (RAS) de residência de Minas Gerais, Brasil, e o intervalo entre diagnóstico e início de tratamento de mulheres que realizaram tratamento ambulatorial (quimioterapia ou radioterapia) para câncer do colo do útero pelo Sistema Único de Saúde (SUS), entre 2001 e 2015. Trata-se de um estudo transversal, recorte de uma coorte, com 8.857 mulheres. Para avaliar a associação da RAS de residência e o intervalo entre diagnóstico e início de tratamento (em dias), foram utilizados modelos de regressão binomial negativa, considerando nível de significância de 5%. Os modelos foram construídos usando blocos de covariáveis sociodemográficas, clínicas e relacionadas ao tratamento. Foi determinado que a RAS de residência das mulheres está associada ao intervalo entre o diagnóstico e o início de tratamento. A RAS Norte foi a região do estado onde a média de tempo para iniciar o tratamento foi menor, e não residir nessa RAS aumenta a média de tempo para iniciar o tratamento entre 24% e 93% em comparação com outras RAS do estado. Fica evidente a disparidade no intervalo entre diagnóstico e início de tratamento entre as regiões do Estado de Minas Gerais. A disponibilidade de serviços habilitados para o tratamento do câncer nas RAS não reflete necessariamente em maior agilidade para início de tratamento. Compreender os fluxos das Redes de Atenção Oncológica e suas diferenças regionais é fundamental para aprimorar políticas públicas que garantam o cumprimento de leis vigentes, como a Lei nº 12.732/2012, que preconiza o início do tratamento de pacientes com câncer em até 60 dias após o diagnóstico.

Published: October 2022

Abstract This study investigated the effect of phytic acid (IP6) in different concentrations and application times on microtensile bond strength (µTBS) and interfacial integrity of universal adhesive to deep dentin. Flat deep dentin surfaces of 48 human molars were either etched with 37% phosphoric acid (PA) for 15 sec (control); or received no acid treatment and universal adhesive was applied directly in a self-etch mode (SE); or divided according to IP6 concentration (C) into two main groups: C1, 0.5%, and C2, 1%. Specimens of IP6 groups were further subdivided into three subgroups according to application time of IP6 (T) where; T1, 15 sec; T2, 30 sec and T3, 60 sec. Single Bond Universal Adhesive was then applied and resin composite blocks were built-up. Forty Specimens were then sectioned to produce resin/dentin beams that were used for µTBS testing using a universal testing machine. The remaining eight specimens were sectioned into slabs that were immersed into ammonical silver nitrate solution and nanoleakage was observed using a field emission scanning electron microscope (FE-SEM). The results showed that the application of IP6 in 0.5% and 1% produced significantly higher µTBS and less nanoleakage compared to PA and SE groups. Also, the application of IP6 for 60 sec recorded the highest µTBS and the lowest nanoleakage followed by 30 sec, and 15 sec respectively. Therefore, conditioning of deep dentin with IP6 enhances µTBS and interfacial integrity of universal adhesive to deep dentin in comparison to PA etching or using the universal adhesive in SE mode.
Notas para uma contribuição à historiografia psicanalítica
Authors: Rosa Camila Terra da , Weinmann Amadeu
Published: October 2022

Resumo Este artigo propõe uma contribuição à historiografia psicanalítica. Para isso, retomamos o texto que consideramos fundador desse campo de debates, A história do movimento psicanalítico, publicado por Freud em 1914, para nele encontrarmos as primeiras pistas de como operar na interface entre psicanálise e história. A partir desse texto inaugural, dedicamo-nos aos estudos de alguns psicanalistas e historiadores que pensaram o enlace entre psicanálise e história, a fim de encontrarmos convergências e divergências sobre o fazer do psicanalista historiador. Por fim, propomos três eixos para uma historiografia psicanalítica, articulados em torno dos conceitos só depois, das Ding e verdade histórica. A partir dessa reflexão de cunho historiográfico, esperamos ser possível pensar de outros modos a história do movimento psicanalítico.

Authors: Bakman Gizele , Uziel Anna Paula
Published: October 2022

Resumo Neste artigo apresentamos uma pesquisa de mestrado cujo objetivo principal foi conhecer o que crianças pensam sobre o que é família e quais critérios utilizam para defini-la. O campo da pesquisa, construído através das pistas do Método Cartográfico, consistiu em 6 entrevistas em grupo, totalizando 22 crianças entre 6 e 11 anos, moradoras da cidade do Rio de Janeiro. As entrevistas incluíram a produção de desenhos de família, recurso utilizado como disparador da discussão. Percebemos que as crianças entrevistadas experimentam flexibilidade para conjugar aspectos que consideram importantes no entendimento dos laços familiares, como afeto, convivência e relações sanguíneas, que se entremeiam, se sobrepõem, se movimentam, nos remetendo ao conceito deleuziano de dobra. Ao focalizarmos o modo como elas entrelaçam seus critérios, concluímos que nos oferecem um olhar amplo sobre as famílias, aberto à multiplicidade, dando maior importância à qualidade afetiva dos relacionamentos.

Resumo Em 2013, no Brasil, emergem na cena política diversos agrupamentos políticos identificados com a direita política e unidos contra a esquerda e a permanência do Partido dos Trabalhadores no governo brasileiro. Este estudo investiga esse fenômeno no contexto da região Nordeste do Brasil. Seu objetivo é compreender como a militância de direita, em uma cidade média nordestina, organiza discursivamente uma identidade para si e para os grupos que elegem como antagonistas. Com o uso do método de análise de discurso, o estudo investiga transcrições de entrevistas realizadas com nove membros dessa militância. As categorias conservador, libertário e liberal foram usadas como posições de autoidentificação por esses militantes. O modo como descrevem essas categorias revela a pluralidade da direita, evidenciando as complexas relações e as contradições presentes no seu interior.

RESUMO O presente trabalho teve como objetivo sintetizar membranas lamelares de óxido de grafeno reduzido (rGO – reduced graphene oxide) sobre um suporte de acetato de celulose e compará-las quanto à rejeição de azul de anilina, por meio de duas metodologias de produção do rGO: redução agregante e não agregante. Inicialmente foram produzidas dispersões de óxido de grafeno (GO – graphene oxide) por uma modificação do método de Hummers, as quais passaram por tratamento termoquímico para redução do GO e foram utilizadas para deposição sobre um suporte de acetato de celulose, utilizando-se o método de filtração assistida por vácuo. Para caracterização das dispersões e membranas foram utilizadas as técnicas de difração de raios X (DRX) e microscopia eletrônica de varredura (MEV), sendo que nas membranas produzidas foram conduzidos testes de estabilidade em água. Para análise da rejeição de azul de anilina, utilizado como material a ser filtrado, os permeados de cada uma das membranas, bem como do substrato como recebido, foram analisados por espectrofotometria UV-Vis, sendo que a concentração do permeado pôde ser estimada a partir de uma curva de calibração previamente produzida. Foram observadas diferenças de estabilidade da membrana, a depender da metodologia de redução utilizada, bem como expressivo incremento de rejeição de azul de anilina em relação ao substrato como recebido de acetato de celulose.
ISOKINETIC KNEEL MUSCLE STRENGTH CHARACTERISTICS IN HIGH JUMP ATHLETES
Authors: Li Zhengjun , Xu Jianhua , Ou Shiwei
Published: October 2022

ABSTRACT Introduction: Vertical jump is inherent to the practice of high jump and demands great capacity of force generation and work of the knee muscles, especially the quadriceps muscle. Due to this demand, imbalances between the extensor and flexor knee muscles may be present, leading to an overload of the musculotendinous structures of the knee joint. Therefore, it is necessary to establish the characteristics of isokinetic muscle strength in the knee joint of these athletes. Objective: This study aimed to analyze the biomechanical properties of the knee flexor and extensor muscles in high jump athletes. Methods: Ten high jumpers volunteered for the experiment. They were divided into experimental and control groups. Both groups performed basic strength training. The experimental group added isokinetic knee muscle training based on this training. Statistical analyses were performed on the training data of the two groups of athletes using relevant mathematical statistics. Results: The high jump consists of four phases being respectively the approach run, the jump itself (impulsion, elevation, transposition), and the fall. The strength of the ankle joint dorsiflexion and plantar flexors was significantly increased in the experimental group of athletes. In contrast, the strength of the plantar flexors in the control group was significantly increased. Statistical differences were found between the two groups (P<0.05). Conclusion: The isokinetic knee joint strength training mode can improve the leg support strength of jumpers. This paper suggests that high jump athletes can further adopt this lower limb strength training method. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Zheng Chaosha
Published: October 2022

ABSTRACT Introduction: Athletes’ physical conditioning is closely related to the type of sport dedicated, training levels, intrinsic conditions of the athletes, type of load, and recovery status after exercise training. There is ample documentation on the physical conditioning of volleyball athletes in normal situations, but the literature is lacking in surveys during competition periods. Objective: To explore the physical conditioning through analysis of body biomarkers in volleyball athletes in competition. Methods: Before and after the summer training, fasting urine and blood samples were collected from five female volleyball players. Biomarkers involving white blood cells, red blood cells, hemoglobin, etc., were detected, recorded, and the data were statistically analyzed. After the general analysis of the sample, a case study of two elite female athletes was conducted. Results: The urea nitrogen value of athlete A decreased from 7.62mmol/L to 4.91mmol/L, and the urea nitrogen value of athlete B decreased from 6.91mmol/L to 6.57mmol/L; the urea nitrogen values of both athletes showed a downward trend. Athlete A’s physical function status decreased significantly after summer training, while Athlete B’s physical function status improved slightly. Conclusion: During the summer training period, it is necessary to perform continuous index measurements on the athletes to increase the timeliness of the data, which is conducive to in-depth analysis of the athletes’ fitness status.

Authors: Yao Yanbing
Published: October 2022

ABSTRACT Introduction: With the gradual improvement of the theoretical system of sports biomechanics and the high requirements of Taekwondo development, the scientific research of Taekwondo is no longer restricted to a monothematic perspective; sports biomechanics is a combination of the complex forms of movement and body changes in the sport, a discipline that combines the principles of mechanics and biology for research. This discipline, allied to the study of sport, contributes to the correct understanding, training, and mastery of movement techniques. Objective: Apply a technical analysis of the taekwondo kick through a sports biomechanics approach. Methods: Using a three-dimensional kinematic motion capture system, volunteers of 58kg, 68kg, 80kg, and three other weight classes, in a total of 30 athletes, participated in this research. The movements included technical kicks and the collection of motion trajectories when hitting the target. Results: There were significant differences in the angle, angular velocity, torque, action time, displacement, and velocity of the lower limb joints of the three weight classes (P<0.05). Conclusion: The higher the athlete’s weight, the lower the body agility; although the striking distance is relatively long, the impact on movement speed is relatively minor.

Resumen Objetivo: analizar el proceso de limpieza de gastroscopios, colonoscopios y duodenoscopios en ocho servicios de salud intrahospitalarios. Método: estudio transversal con 22 endoscopios, de los cuales ocho eran gastroscopios, ocho colonoscopios y seis duodenoscopios, y análisis microbiológico de 60 muestras de los canales de aire/agua (todos los endoscopios) y elevador (duodenoscopios), además de prueba de proteínas. En el análisis de los datos se utilizó estadística descriptiva, con cálculo de frecuencias y medidas de tendencia central. Resultados: el procesamiento de los 22 endoscopios fue monitoreado con el análisis microbiológico de 60 canales. En la prelimpieza, en el 82,3% (14/17) de los equipos se utilizó gasa para limpiar el tubo de inserción. En el 72,3% (17/22) de los casos la inmersión del endoscopio en solución detergente fue incompleta y en el 63,6% (14/22) no hubo estandarización del llenado de los canales. La fricción del canal de biopsia no se realizó en el 13,6% (3/22) de los equipos. En el análisis microbiológico, el 25% (7/32) de las muestras endoscópicas almacenadas dio positivo para crecimiento microbiano (2x101 a 9,5x104 UFC/ml), mientras que después del procesamiento, la contaminación fue del 32% (9/28). Se detectaron residuos de proteína en el canal elevador en el 33% de los duodenoscopios. Conclusión: los resultados indican que hay importantes lagunas en las etapas de prelimpieza y limpieza de los endoscopios que, junto con la presencia de residuos de proteínas y del crecimiento de microorganismos de importancia epidemiológica, indican limitaciones en la seguridad del procesamiento, que pueden comprometer los procesos de desinfección y, por ende, el uso seguro en los pacientes que se someten a esos procedimientos.

Abstract Proteobacteria comprising species of Pseudomonas syringae group cause diseases of many plants around the world. The phytopathogen has a complex taxonomic structure, which is constantly being revised due to the emergence of new molecular and biochemical diagnostic methods. Here for the first time, we describe the genetic and phenotypic diversity of 57 strains of Pseudomonas syringae isolated from affected soybeans, cereals, sunflowers, and other plants in the Russian Federation from 1950 to 2019. Genetic diversity was assessed by Multi Locus Sequence Analysis (MLSA) using fragments of the genes of glyceraldehyde-3-phosphate dehydrogenase (gapdh), the DNA-directed RNA polymerase subunit D (rpoD), gyrase (topoisomerase) B subunit (gyrB), and citrate synthase I (gltA). The synthesis of syringomycin and coronatine by bacteria was assessed by the reaction of susceptible yeast culture, seedlings of barley, tomato, and sunflower, and by presence of toxin genes confirmed by PCR test. The pathogenicity of the strains was confirmed on seedlings of dicotyledonous and monocotyledonous plants of peas, soybean, sunflowers, barley and wheat, as the most affected crops. The sensitivity of bacteria to 10 antibiotics of the main mechanisms of activity and two bactericidal commercial products was tested by standard disc method. The obtained results showed a high genetic homogeneity of the Russian population of P. syringae, which infects various agricultural crops, and an increase in the proportion of antibiotic-resistant strains over the years.

Abstract Despite the high number of fish species described for the Amazon region, the ichthyofauna that inhabits the depths of the main channels of large tropical rivers is one of the least known. In order to know the diversity patterns of these fish in whitewater rivers of the Central Amazon, we used data from the main channel benthic fish assemblage of the Japurá, Purus and Madeira rivers and tested the hypothesis that there are marked spatial and seasonal differences in the composition of the fish community among them. For this, we used a multivariate dispersion test, total β diversity and its decomposition into local (LCBD) and species contribution to β diversity (SCBD). Additionally, we tested for relationships between LCBD values and richness, total abundance, and environmental variables. We categorized species with higher SCBD values into resident or migratory to investigate the potential importance of floodplains to benthic fish assemblage of the main channel of whitewater rivers. Our results corroborate the proposed hypothesis, showing that there are seasonal and inter-river differences in benthic ichthyofauna, being more evident for the Purus River. LCBD showed strong negative relationships with species richness and total abundance, particularly in the Japurá and Madeira rivers in rising season, indicating that rivers and season with high uniqueness in their composition also had low richness and abundance. LCBD was negatively correlated with conductivity and pH, which increased with declining these environmental variables, as observed mainly in Japurá River in both seasons. Approximately one third of the species had higher than average SCBD values and were considered major contributors to β diversity, as well as classified as migratory. This demonstrates the importance of conducting studies that use spatial and seasonal variables, in addition to including the background fish fauna in conservation studies, expanding the protected area and taking into account the different patterns of diversity between rivers. Furthermore, these differences in assemblage composition might be explained by the asymmetrical spatial use of habitats during different seasons, strongly suggesting the importance of the flood-pulse cycle for maintaining diversity in this environment.

ABSTRACT Wild passion fruit species, due to the greater tolerance to environmental stresses, reveal potential as interspecific rootstocks. Passiflora foetida is a wild species potentially tolerant to salinity. Therefore, the objective with the study was to evaluate the effects of irrigation water salinity on the growth of wild passion fruit (P. foetida L.) rootstocks. The experiment was carried out in a protected environment. The treatments consisted of the electrical conductivity of the irrigation water (0.3; 1.0; 2.0; 3.0 and 4.0 dS m-1), distributed in randomized blocks. The assessments were performed at 7, 14, 21, 28 and 35 days after transplanting and consisted of: stem height and diameter, number of leaves, average leaf size, leaf area, and dry matter of shoots, roots and total. In younger rootstocks, the deleterious effects of salinity on height growth and leaf components were observed under lower electrical conductivities, with tolerance increasing with age. However, dry biomass accumulation was more severely restricted by salinity with increasing rootstock age. P. foetida rootstocks are salinity tolerant and can be irrigated with water of up to 4.0 dS m-1.

ABSTRACT Radish and lettuce are two crop vegetables that can be intercropped because they are companion cultures that complement each other. Thus, this study aimed to evaluate agro-bioeconomic returns arising from radish-lettuce intercropping in different equitable amounts of hairy woodrose (Merremia aegyptia) and roostertree (Calotropis procera) biomass at different population densities of lettuce, in the semi-arid environment. The experimental design was in randomized blocks, with treatments arranged in a 4 × 4 factorial scheme with four replicates. The first factor consisted of equitable amounts of M. aegyptia and C. procera biomass at doses of 20, 35, 50, and 65 Mg ha-1 on a dry basis. The second factor comprised four lettuce population densities of 150, 200, 250, and 300 thousand plants ha-1. The lettuce and radish cultivars planted were ‘Tainá’ and ‘Crimson Gigante’, respectively. Expressive agro-bioeconomic returns from this radish-lettuce intercropping were obtained in the land equivalent ratio (LER) of 2.25, a score of the canonical variable Z of 3.00, net income (NI) of 52,270.48 R$ ha-1, respectively, in the biomass amount of 65 Mg ha-1 of the green manures and lettuce population density of 300 thousand plants ha-1. Also, there was a productive efficiency index (PEI) of 0.96 and a competitive ratio (CR) of 2.61 in the biomass amount of green manure of 65 Mg ha-1 and lettuce density of 150 thousand plants ha-1. Using M. aegyptia and C. procera biomass from the Caatinga biome proved to be a viable technology for producers who practice the cultivation of radish and lettuce in intercropping in the semi-arid environment.

ABSTRACT Coffee is one of the main commodities of global agribusiness and of outstanding economic and social relevance for Brazil. The lack of labor and its high cost are factors that worry coffee producers, mainly during the conilon coffee harvesting, which is performed manually. This study aimed to evaluate the efficiency of a self-propelled harvester under different conditions of machine adjustment and conduction of the Coffea canephora crop and measure its influence on the cost of harvesting compared to manual harvesting. Harvesting speed (800 to 1600 m h-1), rotation of the vibrating rod cylinder (1.0 and 1.5 RPM), number of orthotropic branches (one, two, and three), and plants with and without plagiotropic branches in the lower third were assessed. The increase in harvesting speed reduced the efficiencies of stripping and harvesting and defoliation. Increasing from one to three orthotropic branches per plant increased harvesting and stripping efficiencies, fruit loss on the ground, defoliation, and reduced pending load. The management without plagiotropic branches showed higher harvesting efficiency, lower loss on the ground, and lower defoliation. Harvesting speeds from 800 to 1600 m h-1 reduced the total and unit costs up to 62% compared to manual harvesting. Increasing harvesting efficiency above 70% has reduced harvesting costs by up to 79% compared to manual harvesting.
