Fruits of Schinus terebinthifolia Raddi were investigated. A fast and efficient method for the simultaneous determination of 11 polyphenolic substances by high performance liquid chromatography-diode array detector (HPLC-DAD) was applied. Limits of quantification ranged between 0.78 and 3.14 mg L-1. High concentrations of kaempferol were found. An exploratory evaluation was performed using principal component analysis (PCA) for fruit origin differentiation. Total phenolic content (TPC) ranged from 274 to 517 mg GAE 100 g-1; total flavonoid content (TFC) ranged from 101 to 283 mg QE 100 g-1. In vitro analyses showed that antioxidant capacity with 2,2-diphenyl-1-picrylhydrazyl (DPPH) ranged from 1.7 to 7 µM DPPH 100 g-1. The bacteriostatic and bactericidal effect were also evaluated against: Bacillus subtilis, B. cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella choleraesuis, Candida albicans and C. glabrata, using broth microdilution assay. It can be inferred that S. terebinthifolia Raddi fruit has the potential to act as an ally in the search for new alternatives in the action against pathogens, and it can be used as a potential natural antioxidant and antimicrobial agent. Metals (Cu, Fe, Mg, Mn and Zn) were also determined by flame atomic absorption spectrometry (FAAS), with emphasis on high concentrations of Mg, Zn and Fe. investigated 1 chromatographydiode chromatography diode HPLCDAD HPLC DAD (HPLC-DAD applied 078 0 78 0.7 314 3 14 3.1 L1.

In the Amazon, Euterpe oleracea Mart. (açaí), is part of the identity of traditional communities, and the fruit is integrated into their everyday sociocultural dynamics. Hydrolysis and pyrolysis of residual biomass can be alternatives to yield sugars, ethanol, biochar and bio-oil. The açaí seeds subjected to oxidative pretreatment followed by acid hydrolysis increased cellulose to fermentable sugars (reaching 23.5%) and second-generation ethanol production (17.441 L t−1). Açaí oil (ca. 30%) was extracted using a Soxhlet apparatus (using hexane as solvent) and detected through gas chromatography coupled to mass spectrometry (GC-MS), where acids accounted for 82.43% of the total composition, while alcohols comprised only 13.15%. For pyrolysis, temperatures (500 and 550 °C), time (20 and 30 min), and activation temperature (750 and 800 °C) were evaluated, resulting in yields of ca. 22% for biochar and 30% for bio-oil. For the bio-oil, the main compounds detected by GC-MS were acids (16.3%), aldehydes (13.08%), amides (12.19%), alcohols (6.72%), and phenols (4.64%). The obtained biochar displayed surface area values of 553.7 m2 g−1 and 10% crystallinity, indicating its more amorphous nature.

Abstract Alternatives have been studied in order to minimize the major environmental impacts arising from the production of cement and steel. Alternatives include adopting composite cements with the incorporation of alternative materials, to reduce the need for cement in the mixtures. Therefore, this study worked on the viability of incorporating steel residues in the mechanical performance of mortar and durability, evaluating the partial and total replacement of Portland Cement (PC) by granulated blast furnace slag (EGAF) and residue from the Desulfurization process of flue gases (FGD). The results found show that the association of these residues in place of cement improved the mechanical performance of the mortars by around 40%. In addition to having a lower modulus of elasticity and lower absorption of water by capillarity, properties that significantly increase the durability of the matrices. The contaminant leaching results did not show any contaminants in harmful amounts. The studies presented demonstrate that the simultaneous use of FGD and EGAF to replace Portland cement were satisfactory, obtaining better mechanical and durability performances than the reference ones, enabling the use of these residues in the production of mortars with low cement content. materials mixtures Therefore PC (PC (EGAF FGD. .

Resumo Alternativas vêm sendo estudadas com o intuito de minimizar os grandes impactos ambientais provenientes da produção do cimento e aço. Inclusive, adotando cimentos compostos, com incorporação de materiais alternativos, diminuindo a necessidade de cimento nas misturas. Por conseguinte, este trabalho estudou a viabilidade de incorporação de resíduos siderúrgicos no desempenho mecânico e de durabilidade de argamassas, avaliando a substituição parcial e total do Cimento Portland por escória granulada de alto-forno moída (EGAF) e resíduo proveniente do processo de Dessulfurização de Gases de Combustão (FGD). Os resultados encontrados mostram que a associação desses resíduos em substituição ao cimento melhorou cerca de 40% o desempenho mecânico das argamassas. Além de apresentarem um menor módulo de elasticidade e menor absorção de água por capilaridade, propriedades que aumentam significantemente a durabilidade das matrizes. Os resultados de lixiviação de contaminantes não apresentaram nenhum contaminante em quantidade prejudicial. Os estudos apresentados demonstram que a utilização de FGD e EGAF simultâneos para substituir o Cimento Portland foram satisfatórios, obtendo desempenhos mecânicos e de durabilidade superiores aos de referência, viabilizando a utilização desses resíduos na produção de argamassas com baixo teor de cimento. aço Inclusive compostos alternativos misturas conseguinte altoforno alto forno (EGAF FGD. .

Resumo A expansão desordenada das cidades é um desafio global que afeta o desenvolvimento urbano. Neste estudo, é analisado o crescimento urbano em uma cidade média durante cinco décadas, com enfoque na forma urbana e aplicação de mais de 20 métricas espaciais associadas à mensuração da geometria da expansão físico-territorial no ambiente construído. Os padrões de crescimento são analisados à luz do fenômeno espraiamento urbano e sob a perspectiva da teoria de Difusão-Coalescência. São discutidas as limitações inerentes às métricas existentes, assim como elencadas alternativas que as superam por mensuração das propriedades de Compacidade, Fragmentação, Complexidade e Dispersão concomitantemente. Os resultados demonstraram a ocorrência de fases distintas no crescimento urbano ao longo das décadas: Difusão de uma forma inicialmente compacta em partes menores nas periferias; e Transição para crescimento com agrupamento dessas partes, elevando a compacidade. Essa oscilação sugere aderência à teoria da Difusão-Coalescência, com ocorrência de espraiamento urbano (entre 1966 e 1976) seguida de aumento da compacidade nas décadas subsequentes (1976-2006). Após 2006 os resultados são ambíguos, possivelmente associados a fatores intervenientes de planejamento. A discussão dos resultados destaca a relevância da quantificação do crescimento urbano por meio de métricas, e traz conceitos importantes atualmente limitados à literatura internacional. estudo 2 físicoterritorial físico territorial construído DifusãoCoalescência.

Abstract The disorderly expansion of cities is a global challenge that impacts urban development. In this paper, we analyse the urban growth in a medium-sized city over five decades, focusing on urban form and employing more than 20 spatial metrics associated with the geometry of physical-territorial expansion in the built environment. We examine the growth patterns in the context of the urban sprawl phenomenon and the Diffusion-Coalescence theory perspective. We discuss the inherent limitations of existing metrics and raise alternatives that simultaneously address the properties of Compactness, Fragmentation, Complexity, and Dispersion. The results reveal distinct phases in urban growth over the decades, from diffusion of an initially compact form into smaller parts on the periphery; to a transition towards more compact growth. This oscillation suggests adherence to the Diffusion-Coalescence theory, with urban sprawl occurring between 1966 and 1976, followed by increased compactness in subsequent decades (1976-2006). After 2006, the results became ambiguous, possibly due to intervening planning factors. The discussion of the findings underscores the importance of quantifying urban growth using metrics and introduces concepts that have been hitherto limited to international literature. development paper mediumsized medium sized 2 physicalterritorial physical territorial environment DiffusionCoalescence Diffusion Coalescence perspective Compactness Fragmentation Complexity Dispersion periphery 196 1976 19762006. 19762006 2006 .

ABSTRACT: The aim of this article is to present different legal strategies for the financial sustainability of Colombian biobanks. For that purpose, this work criticizes the sale of human biological samples as a means for sustainability, and proposes different legal alternatives based on, among others, the compensation for the costs associated with the maintenance of the biobank, services of sample collection for third parties or political commitment on the part of the State.

RESUMEN. El objetivo de este artículo es presentar posibles estrategias jurídicas para la sostenibilidad financiera de los biobancos en Colombia. Para tal propósito, critica la posibilidad de comercializar muestras biológicas humanas mediante contratos onerosos y estudia algunas alternativas de sostenimiento basadas, por ejemplo, en la compensación económica por los costos asociados al mantenimiento, el servicio de colección de muestras a terceros o el compromiso político por parte del Estado.

ABSTRACT BACKGROUND: En bloc hysterectomy is defined as the removal of the pregnant uterus with its gestational content in situ. The indications for performing this en bloc surgery are neoplastic processes, as the most frequent cause; septic processes, trophoblastic disease and hemorrhage secondary to abnormal placental insertion, however, it is a controversial procedure, and with little updated literature. CLINICAL CASE: 45-year-old patient with a pregnancy of 8 weeks and 5 days, with giant uterine myomatosis associated with pulmonary thromboembolism who decided to voluntarily terminate the pregnancy, and it was decided to perform en bloc hysterectomy. CONCLUSIONS: En bloc hysterectomy is a surgery rarely performed at present, however, this surgical approach is a safe and effective option for the voluntary termination of pregnancy, and it should not be ruled out among the surgical treatment alternatives, always individualizing each patient.

Abstract This paper analyses some problems in the university following the leitmotif of the link between the population as a whole and the institution. The critique, in the literal sense of dissection and discernment, aims to underline the boundary between those problems and the potential alternatives that a reflection on the foundations of the university may reveal. The steps to develop are, in the first place, the outline of the link between university and population according to their mutual influence. Secondly, the determination of the problems that the formation of the university usually presents to the people. Thirdly, the comprehension of the alternative, taking as an example the sense of the college degree and, in particular, the PhD. And, to conclude, based on what was previously exposed, the role of the philosophy inside the university.

Resumen Este artículo examina algunas problemáticas en la universidad siguiendo el hilo conductor de la relación entre la población en su conjunto y la institución. La crítica, en el sentido literal de disección o discernimiento, se propone subrayar el límite entre esos problemas y las alternativas potenciales que una reflexión sobre los fundamentos de la universidad pueda revelar. Los momentos a desarrollar son, en primer lugar, el esbozo de la relación entre universidad y población según su influencia mutua. En segundo lugar, la determinación de las problemáticas que para el pueblo suele presentar la formación de la universidad. En tercer lugar, la comprensión de la alternativa tomando como ejemplo el sentido del título universitario y, en concreto, el de doctor. Y, para concluir, el papel de la filosofía dentro de la universidad con base en lo previamente expuesto.

Summary: The cocoa crop is very susceptible to nutritional deficiencies and moniliasis caused by the phytopathogen Moniliophthora roreri. One of the alternatives to synthetic chemicals are compounds based on silicon (Si). In the present investigation, the ef fect of silicon as a biostimulant in cocoa cultivation and as a biological control agent for M. roreri was evaluated. In the experiment, five Si treatments were used: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) and T4 (1.5 kg ha-1) and a control treatment (without application). Production indicators, ear number, fresh and dry weight of almonds, dry weight of 100 almonds and crop yield were determined. In addition, the incidence and severity of the disease at 60, 120 and 180 days af ter the application of Si and the ef ficiency of the treatments. The significantly higher results for the variables: Production, ear number, fresh and dry weight of almond and dry weight of 100 almonds, were obtained by applying 4 kg ha-1 of Si, all doses of Si exceeded the control (P ≤ 0.05) in the variables related to production. In the control of the phytopathogen (M. roreri), the dose of 4 kg ha-1 Si decreased the incidence and severity of the disease by more than 50%. The application of Si can be an option in cocoa cultivation as a biostimulant and biological control agent for M. roreri.

Resumen: El cultivo del cacao es muy susceptible a deficiencias nutrimentales y a la moniliasis ocasionada por el fitopatógeno Moniliophthora roreri. Una de las alternativas a los productos químicos sintéticos son los compuestos a base de silicio (Si). En la presente investigación se evaluó el efecto del silicio como bioestimulante en el cultivo de cacao y agente de control biológico de M. roreri. En el experimento se utilizaron cincos tratamientos de Si: T1 (4.00 kg ha-1), T2 (3.00 kg ha-1), T3 (2.00 kg ha-1) y T4 (1.5 kg ha-1) y un tratamiento control (sin aplicación). Se determinaron los indicadores de producción, número de mazorca, peso fresco y seco de almendras, peso seco de 100 almendras y el rendimiento del cultivo. Además, de la incidencia y severidad de la enfermedad a los 60, 120 y 180 días después de la aplicación del Si y la eficiencia de los tratamientos. Los resultados significativamente superiores para las variables: Producción, número mazorca, peso fresco y seco de almendra y peso seco de 100 almendra, se obtuvieron mediante la aplicación de 4 kg ha-1 de Si, todas las dosis de Si superaron al control (P ≤ 0.05) en las variables relacionas a la producción. En el control del fitopatógeno (M. roreri), la dosis de 4 kg ha-1 Si disminuyó la incidencia y la severidad de la enfermedad en más del 50%. La aplicación de Si puede ser una opción en el cultivo de cacao como bioestimulante y agente de control biológico de M. roreri.

Resumen El objetivo de este trabajo fue evaluar el efecto combinado de dos tácticas de biocontrol de plagas: la biofumigación con Brassicajuncea y la inoculación de Trichoderma harzianum, sobre el crecimiento in vitro del patógeno Phomopsis spp., agente etiológico de la cancrosis en el cultivo de pecán (Carya illinoinensis). Se trituraron plantas de B. juncea y se colocaron en envases de poliestireno en dosis de 10 y 30 g. Luego, en cada uno de estos recipientes se introdujo una caja de Petri con un disco con micelio dePhomopsis spp. o T. harzianum o ambos hongos (cultivo dual). Se incubó en cámara de cultivo. Los parámetros evaluados fueron la superficie de las colonias y el porcentaje de inhibición miceliar de Phomopsis spp. Los datos se analizaron con estadística no paramétrica mediante la prueba de Kruskal-Wallis. Se obtuvieron los siguientes resultados: i) B. juncea no afectó el crecimiento de T. harzianum; ii) la dosis de 30 g de B. juncea suprimió completamente el crecimiento de Phomopsis spp.; iii) T. harzianum inhibió significativamente el crecimiento de las colonias de Phomopsis spp.; iv) la combinación de T. harzianum y la biofumigación con 10 g de B. juncea mostró sinergia sobre el control del crecimiento de Phomopsis spp. La biofumigación con B. juncea, la aplicación de T. harzianum y la combinación de ambas técnicas podrían ser alternativas promisorias para el control biológico de Phomopsis spp.

Abstract This work aimed to evaluate the combined effect of two pest biocontrol strategies: biofumigation with Brassica juncea and inoculation of Trichoderma harzianum, on the in vitro growth of the pathogen Phomopsis spp., an etiological agent of canker disease in pecan crops (Carya illinoinensis). B. juncea plants were crushed and placed in polystyrene recipients in doses of 10 and 30 g. Then, a Petri dish was introduced to each recipient, with a disk with a grown mycelium of Phomopsis spp. or T. harzianum, or both fungi (dual culture). Treatments were incubated in a culture chamber. The parameters evaluated were colonies’ surface area and percentage of mycelial inhibition of Phomopsis spp. Data were analyzed with non-parametric statistics using the Kruskal-Wallis test. The results indicated that: i) B. juncea did not affect the growth of T. harzianum; ii) the 30 g dose of B. juncea completely suppressed the growth of Phomopsis spp.; iii) T. harzianum significantly inhibited the growth of Phomopsis spp. colonies; iv) the combination of T. harzianum and biofumigation with 10 g of B. juncea showed synergy on the growth control of Phomopsis spp. Biofumigation with B. juncea, the application of T. harzianum, and the combination of both techniques could be promising alternatives for the biological control of Phomopsis spp.

ABSTRACT Social technology is based around three axes: community, environmental protection and economic solidarity. The páramo itself is a vital ecosystem for water regulation as it is the source of water supplies for human consumption and performance of economic activities. This article intends to identify the limitations to apply social technology to the protection of the páramo in the central highlands of Ecuador, where processes of self-management, empowerment, participation, agreement-making, cooperation and pursuit for collective welfare have been observed. The methodology is quantitative within the framework of discourse analysis. The results show that, in order to reach a large agreement for the protection and recovery of the páramo, involving all of the communities settled in the area, it is necessary to overcome limitations mostly related to the lacking attention by the government in regards to basic utilities, management plans for conservation areas and studies for economic alternatives allowing communities to subsist in the lower zones, compromising not to extend their agricultural borders further into the highlands. This information helps strengthen natural resource management from a new perspective.

RESUMEN La tecnología social se fundamenta en tres ejes: la comunidad, el cuidado ambiental y la solidaridad económica. Por su parte, el páramo es un ecosistema vital en la regulación hídrica porque sustenta el suministro de agua para consumo humano y el desarrollo de actividades económicas. Este artículo se centra en identificar las limitaciones para aplicar los fundamentos de la tecnología social en la protección del páramo, ubicado en la Sierra central del Ecuador, lugar donde se observan procesos de autogestión, empoderamiento, participación, logro de acuerdos, cooperación y búsqueda del bienestar colectivo. La metodología es cualitativa, en el marco del análisis del discurso. Los resultados muestran que, para que exista un gran acuerdo de protección y recuperación del páramo, entre todas las comunidades asentadas en esta zona, es necesario vencer limitaciones relacionadas, principalmente, con la falta de atención por parte del gobierno en temas de servicios básicos, planes de manejo para áreas de conservación y estudio de alternativas económicas que permitan a las comunidades subsistir en las zonas bajas y comprometerse a no ampliar la frontera agrícola hacia zonas altas. Esta información contribuye a fortalecer la gestión de recursos naturales desde una nueva perspectiva.

RESUMO A tecnologia social baseia-se em três eixos: a comunidade, o cuidado ambiental e a solidariedade econômica. O páramo é um ecossistema vital para a regulação hídrica pois ele fornece agua para o consumo humano e a realização de atividades económicas. Esse artigo focou-se na identificação das limitações para aplicar os fundamentos da tecnologia social para a proteção do páramo, situado na Sierra central de Equador, sítio onde pode-se observar processos de autogestão, empoeiramento, participação, efetuação de acordos, cooperação e procuração de um bem-estar coletivo. A metodologia é qualitativa, dentro do contexto da análise do discurso. Os resultados mostram que, para ter um acordo grande para a proteção e recuperação do páramo, com todas as comunidades estabelecidas na zona, é necessário vencer limitações relacionadas principalmente à falta de atenção do governo em relação à serviços básicos, planes de gestão de áreas de conservação e estudo de alternativas económicas que permitam que as comunidades possam subsistir nas zonas baixas, e comprometer-se a não estender a fronteira agrícola em direção às zonas altas. Essa informação contribui a fortalecer a gestão de recursos naturais com uma nova perspectiva.

Abstract Equitable and permanent access to public services is not always a priority for local management, especially in those territories and historically neglected populations. This contribution argues that in Copoya, a mostly ejido locality in the Metropolitan Zone of Tuxtla Gutiérrez, state and community service for drinking water supply is inefficient. The situation has worsened with urban growth and demand for land throughout the twentieth century. Interviews, field visits and press releases show that residents, due to the lack of water, look for alternatives such as purchasing pipes, backyard wells and untreated water systems. These alternatives do not solve the underlying issue and deepen their poverty and socio-territorial inequality. The article concludes that poor investment in projects does not allow a solution for the supply in the short and medium term.

Resumen El acceso equitativo y permanente a servicios públicos no siempre es una prioridad para la gestión local, en especial en territorios y poblaciones históricamente rezagadas. Esta contribución sostiene que en Copoya, localidad mayoritariamente ejidal de la Zona Metropolitana de Tuxtla Gutiérrez, el servicio estatal y comunitario por el suministro de agua potable no es eficiente. El problema se agudizó con el crecimiento urbano y la demanda por la tierra durante el siglo XX. A partir de entrevistas, recorridos de campo y notas de prensa, se destaca que la escasez del líquido lleva a sus residentes a buscar alternativas como la compra de pipas, pozos de traspatio y sistemas de agua no tratada que no resuelven el tema de fondo y que profundizan la pobreza y la desigualdad socioterritorial. Se concluye que la inexistencia de proyectos de inversión no permite una salida para el abastecimiento en el corto y mediano plazo.

Abstract This contribution identifies the socio-environmental dynamics that development policies have generated on community mangroves in three key moments of Mexican history: the 1917 Constitution, the industrialization of the 1950s, and the 1985 neoliberal reforms. Through eight case studies and 180 semi-structured interviews, a conceptual input shapes three scenarios (community, touristified and conserved mangroves) and fifteen categories that synthesize these dynamics. Mangroves are going through a continuous crisis that is arguably provoked by development policies that neglect local institutions and impoverish local inhabitants. This article offers alternatives that the federal government could take into consideration to manage these areas more effectively at the environmental and territorial levels.

Resumen Este aporte identifica las dinámicas socioambientales que las políticas de desarrollo han generado sobre los manglares comunitarios en tres momentos clave de la historia mexicana: la Constitución de 1917, la industrialización de la década de 1950 y las reformas neoliberales de 1985. Mediante ocho estudios de caso y 180 entrevistas semiestructuradas, se elaboró un insumo conceptual de tres escenarios (manglares comunitarios, turistificados y conservados) y quince categorías que sintetizan estas dinámicas. Los manglares atraviesan una crisis histórica que provocarían las políticas de desarrollo que no atienden si no que debilitarían a las instituciones locales y empobrecerían a los habitantes de las localidades. Los autores ofrecen recomendaciones para que la gestión del gobierno federal sea más efectiva a nivel ambiental y territorial.

ABSTRACT Sentence 1364-17-EP/23 of Constitutional Court and article 233 of the CRE regarding embezzlement seems to be closed. It is stated that both public servants and the ones who do not hold this condition can be authors regardless of their conduct. The resolution is not acceptable as it did not confront whether the content of the constitutional precept was sufficient to comply with the determination required to classify a conduct. The debate cannot be closed without reaching these levels of analysis. The aim of this article is to challenge this decision with arguments that were not considered and can be used to question the conclusions reached. From the explanation of what an intraneus and an extraneus are, other ways of interpreting article 233 are proposed. Among the alternatives, the selected is the one that is believed to be in harmony with the entire system of regulations. Article 233 establishes the need to sanction to non-public and private servants as perpetrators of embezzlement. However, it is not enough to be applied directly. It is the principle of legality that fulfills the mandate of determination. Finally, it is highlighted that the criminal law does contemplate cases where people without the status of public servants may intervene as perpetrators, cases in which there is certainty about the prohibited conduct.

RESUMEN La Sentencia 1364-17-EP/23 de la Corte Constitucional aparentemente cerró la discusión sobre el alcance del art. 233 de la CRE en lo que respecta al peculado. Se afirma serían autores tanto servidores públicos como sujetos que no ostenten esta condición, independientemente de sus conductas. La resolución es insatisfactoria. En la misma no se confrontó si el contenido del precepto constitucional era suficiente para cumplir con la determinación que requiere la tipificación de una conducta. El debate no puede cerrarse sin alcanzar estos niveles de análisis. El objetivo de este artículo es desafiar esta decisión, presentando argumentos que no fueron considerados, y a través de estos, cuestionar las conclusiones alcanzadas. Desde la explicación de lo que es un intraneus y un extraneus, se plantea otras formas de interpretar el art. 233. Entre las alternativas, se selecciona la que se cree que guarda armonía con todo el sistema de normas. El art. 233 fija la necesidad de que en el peculado se sancione como autores a no servidores públicos y a privados, pero no es suficiente para ser aplicado directamente. Es el principio de legalidad el que cumple con el mandato de determinación. Finalmente, se resalta que la norma penal sí contempla supuestos donde pueden intervenir como autores personas sin la calidad de servidores públicos, casos en los que existe certeza sobre la conducta prohibida.

ABSTRACT It is essential to address procedural issues regarding deprivation of liberty, as there is currently a heated discussion in Colombia regarding whether this right should be restricted once a guilty verdict has been issued, particularly when prohibitions exist regarding punitive benefits. Two contrasting positions are being considered in jurisprudence. The objective is to resolve that, when faced with a similar legal issue, two different alternatives are being decided upon, both of which affect the right to liberty and consequently, the various consequences of incarceration. Thus, we will begin by emphasizing the importance of liberty as a fundamental prerequisite, followed by the identification of the two opposing positions regarding the same situation, and subsequently, the significance of the role of the argumentative judge will be addressed. Utilizing a qualitative methodology, which involves studying the topic through jurisprudence, doctrine, and literature, it will be inferred that limitations on the right to liberty within a contested procedural scenario may stem from various evaluative positions, and therefore, only a plausible result derived from the guarantee of motivation is foreseeable.

RESUMEN Indispensable es tratar temas procesales respecto a la privación de la libertad, presentándose en la actualidad una discusión latente en Colombia, en la que se valora argumentativamente si se debe restringir para una persona este derecho, una vez se ha dictado el sentido del fallo condenatorio cuando existan prohibiciones respecto a beneficios punitivos, denotándose dos posturas de la jurisprudencia que se contraponen. El objetivo perseguido es resolver que frente a un problema jurídico similar se viene decidiendo con dos alternativas distintas que comprometen el derecho a la libertad y, con ello, el despliegue de las múltiples consecuencias del encierro. Así, se iniciará fijando la categoría de la libertad como un presupuesto máximo; enseguida se ubicarán las dos posiciones contrapuestas frente a una misma situación y, a partir de ello, se vinculará al trabajo la trascendencia del rol del juez argumentador. Con apoyo de una metodología cualitativa, que involucra el estudio del tema por medio de jurisprudencia, doctrina y bibliografía, se colegirá que las limitaciones del derecho a la libertad que están en un escenario procesal en pugna pueden deberse a múltiples posiciones valorativas, y debido a ello, solamente se otea un resultado plausible derivado de la garantía de la motivación.

RESUMO A salinidade é um dos fatores mais limitantes para a produtividade agrícola, pois afeta tanto as trocas gasosas quanto o metabolismo das plantas. Porém, com o crescimento populacional e a busca constante por alternativas para aumentar a produtividade, a irrigação com águas de salinidade moderada parece ser viável para potencializar a fruticultura no Brasil, especialmente nas regiões semiáridas, onde a maioria das águas tem alta concentração de sal e são as únicas fontes disponíveis para o produtor. Neste contexto, o objetivo deste estudo foi avaliar os efeitos da salinidade da água de irrigação nas trocas gasosas e na qualidade pós-colheita dos frutos do melão amarelo ‘Goldex’ (Cucumis melo L.) nas fases de colheita. Os tratamentos consistiram de duas condutividades elétricas da água de irrigação (CEa - 0,8 e 4,0 dS m-1) e oito etapas de colheita (54, 56, 58, 60, 62, 64, 66 e 68 dias após o transplantio), dispostas em forma de esquema fatorial 2 × 8 e delineamento inteiramente casualizado. Nas condições de salinidade impostas durante as etapas de avaliação, o melão amarelo ‘Goldex’ manteve estáveis suas trocas gasosas básicas. A massa e o número de frutos por planta foram reduzidos pela salinidade da água de irrigação, mas os frutos continuaram classificados como comercializáveis, o que torna a irrigação com água salina até 4,0 dS m-1 uma alternativa viável para a produção de melão amarelo, principalmente em regiões onde há baixa disponibilidade de água de boa qualidade, o que pode potencializar a fruticultura no semiárido. agrícola plantas Porém Brasil semiáridas produtor contexto póscolheita pós ‘Goldex Goldex Cucumis L.

ABSTRACT Salinity is one of the most limiting factors for agricultural productivity, as it affects both gas exchange and plant metabolism. However, with population growth and the constant search for alternatives to increase productivity, irrigation with water of moderate salinity appears to be feasible to enhance fruit cultivation in Brazil, especially in semi-arid regions, where most waters have high salt concentration and are the only available source for the producer. In this context, the objective of this study was to evaluate the effects of irrigation water salinity and harvest stages on gas exchange and post-harvest fruit quality of ‘Goldex’ yellow melon (Cucumis melo L.). The treatments consisted of two electrical conductivities of irrigation water (ECw - 0.8 and 4.0 dS m-1) and eight harvest stages (54, 56, 58, 60, 62, 64, 66, and 68 days after transplanting), arranged in a 2 × 8 factorial scheme and a completely randomized design. Under the salinity conditions imposed during the evaluation stages, the ‘Goldex’ yellow melon maintained its basic gas exchanges stable. The mass and number of fruits per plant were reduced by the salinity of the irrigation water, but the fruits continued to be classified as marketable, which makes irrigation with saline water up to 4.0 dS m-1 a viable alternative for the production of yellow melon, especially in regions where there is low availability of good quality water, which can enhance fruit growing in the semi-arid region. productivity metabolism However Brazil semiarid semi arid producer context postharvest post ‘Goldex Goldex Cucumis L..
