A RESOLUÇÃO N.º 125/2010 DO CNJ COMO POLÍTICA PÚBLICA DE TRATAMENTO ADEQUADO AOS CONFLITOS NAS RELAÇÕES FAMILIARES: EM DIREÇÃO À PROTEÇÃO DA DIGNIDADE DA PESSOA HUMANA E A EFETIVAÇÃO DOS DIREITOS DA PERSONALIDADE
Authors: Gomes Rodrigues Fermentão Cleide Aparecida , Silva Fernandes Ana Elisa
Published: June 2020

A presente pesquisa propõe analisar a Resolução n.º 125/2010 do Conselho Nacional de Justiça como política pública de resolução de conflitos familiares na contemporaneidade, que conduz à proteção integral da pessoa e à dignidade humana e a efetivação dos direitos da personalidade. A família contemporânea sofre com o aumento de conflitos em sua vivência. Surge a necessidade de discussão a respeito da resolução desses conflitos, dotados de alta carga emocional, e, portanto, passíveis de violação à dignidade humana e direitos da personalidade. A metodologia utilizada na pesquisa será de pesquisa bibliográfica do tipo descritiva em artigos científicos em periódicos nacionais e internacionais, livros, revistas e jornais, sendo que o método será o hipotético-dedutivo, pois esse é um processo que visa a identificação de um problema e a formulação de hipóteses a serem testadas. O objetivo da Resolução do CNJ conduz à pacificação social, protegendo a pessoa, sua dignidade e direitos, bem como suas subjetividades pois leva em consideração as emoções, motivos e interesses causadores do conflito, questões estas últimas que não são analisadas na via jurisdicional tradicional, e ainda reconhece autonomia da vontade, liberdade e igualdade entre os litigantes e inclui os indivíduos como participantes da construção da solução consensual.

Authors: Cardin Valéria Silva Galdino , Santos Jamille Bernardes da Silveira Oliveira dos
Published: June 2020

A intersexualidade é caracterizada pelo nascimento de uma pessoa com características físicas relacionadas tanto ao sexo masculino quanto feminino. No Brasil, atualmente, é recomendado pelo Conselho Federal de Medicina que, ao se verificar esta situação, denominada no meio médico como Anomalia de Diferenciação Sexual (ADS), a criança seja submetida a exames complementares para determinar o sexo predominante e, posteriormente, será realizada a cirurgia de correção da genitália ambígua. Diante desta situação, este artigo, por meio do uso de pesquisa bibliográfica, possui por objetivo expor como a intersexualidade é vista no meio médico e jurídico, os contornos bioéticos do trato médico e, por fim, um contraponto destas abordagens em relação ao direito ao próprio corpo, que é um direito da personalidade. O trabalho não é conclusivo, mas reflexivo e busca trazer maior visibilidade para a situação das pessoas intersexuais.

Authors: Dong Wenfa , Chen Dingfang , Tang Ruogu
Published: June 2020

In this work, ABS-g-MAH was used as the compatibilizer in poly carbonate/acrylonitrile styrene acrylate/poly(methyl methacrylate) blends. The polymer blends were prepared via a two-step method: first, raw PC, ASA, PMMA resins and ABS-g-MAH additives were completely mixed and granulated by extrusion molding, and then the standard PC/ASA/PMMA blends samples were obtained by injection molding. A comprehensive characterizations were performed on the PC/ASA/PMMA blends of their morphologies, mechanical properties and thermal properties. The results showed that the addition of ABS-g-MAH could promote the compatibilities among PC, ASA and PMMA, and ABS-g-MAH would significantly alter the mechanical and thermal properties of blends. In addition, the modified PC/ASA/PMMA was well compatible with natural rubber and cause less cytotoxicity when interacting with cells.

Published: June 2020

Emergence of severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infection has given rise to COVID-19 pandemic, that is wreaking havoc worldwide. Therefore, there is an urgent need to find out novel drugs to combat SARS-CoV-2 infection. In this backdrop, the present study was aimed to assess potent bioactive compounds from different fungi as potential inhibitors of SARS-CoV-2 main protease (Mpro) using an in-silico analysis. Nearly 118 bioactive compounds were extracted from Dictyophora indusiata, Geassstrum triplex and Cyathus stercoreus and identified using HR LC/MS analysis. Of which, only bergenin (D. indusiata), quercitrin (G. triplex) and dihydroartemisinin (C. stercoreus) were selected based on their medicinal uses, binding score and active site covered. The 6LU7, a protein crystallographic structure of SARS-CoV-2 Mpro, was docked with bergenin, quercitrin and dihydroartemisinin using Autodock 4.2 and the binding energies obtained were -7.86, -10.29 and -7.20 kcal/mol, respectively. Bergenin, quercitrin and dihydroartemisinin formed hydrogen bond, electrostatic interactions and hydrophobic interactions with foremost active site amino acids THR190, GLU166, GLN189, GLY143, HIS163, HIS164, CYS145 and PHE140. Present investigation suggests that these three drugs may be used as alternative inhibitors against SARS-CoV-2 Mpro. However, further research is necessary to assess in vitro potential of these drugs. To the best of our knowledge, present investigation reported these three bioactive compounds of fungal origin for the first time.

Published: June 2020

Yariv reagents are widely used tools to study plant proteoglycans known as the Arabinogalactan proteins (AGPs). Despite widespread use of the Yariv reagent in the study of AGPs and several reports of synthetic protocols, there remains a lack of a simple procedure to obtain pure Yariv reagents. We report our optimized protocols to address the purification issues faced upon synthesis of Yariv reagents. Additionally, we report challenges that make characterization difficult such as peak broadening in NMR due to Yariv-water interactions. We also show ways of processing Yariv reagents to overcome the characterization issues caused by peak broadening.

Published: June 2020

We report here that a fluorescent benzobisimidazolium salt (TBBI) can be used for the fluorescent and colorimetric detection of carbonyl sulfide (COS) over related heterocumulenes including CO2 and CS2 in wet MeCN. The reaction between TBBI and COS in the presence of fluoride yields a highly fluorescent (lem = 354 nm) and colored product (lex = 321 nm), that is readily observed by the naked eye. We view these results as a first step toward developing activity-based probes for COS detection.

Published: June 2020

The Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused coronavirus disease-2019 (COVID-19) pandemic. Despite the intensive research currently, there are no therapeutics and vaccines available. As the main protease (MPro) plays a vital role in SARS-CoV-2, it is an attractive drug target. Herein we report, potential inhibitors form natural products and synthetic drugs against MPro. In detail, we studied the interaction of inhibitors (Curcumin, Theaflavin, Deserpidine, Betulinic acid, Sinigrin, Emodin, Leptodactylone, Synthetic drugs, Lopinavir, Ritonavir, Indinavir, Amprenavir, Darunavir, Nelfinavir, Remdesivir, Saquinavir, Sivelestat, Galidesivir, and Favipiravir) with the catalytic site of MPro. Lastly, ADME (Absorption, Distribution, Metabolism, and Excretion) properties of Natural products and synthetic drugs are explored. We identified eight potential inhibitors against MPro.

We report the synthesis of novel tetraplatinated metalloporphyrin-based photosensitizers (PSs) for photodynamic therapy (PDT), their characterization, cellular uptake and localization, as well as the determination of their in vitro light-induced anticancer properties. The PSs show excellent phototoxic indexes up to 5800 against HeLa cells, which is, to the best of our knowledge, the highest value reported for any porphyrin so far. Furthermore, isotopic labelling of the porphyrin with a highly enriched 67Zn isotope was performed in order to determine the distribution ratio of zinc to platinum by ICP-MS, allowing to differentiate between naturally occurring zinc and 67Zn that was introduced into the cells by the PS. We conclude that the platinum units within the platinum-PS conjugates help to solubilize the PS and, at the same time, act as cell-penetrating vectors, enhancing the efficiency of the PS without causing a significant dark toxicity.

Authors: Burn Matthew J. , Popelier Paul
Published: June 2020

FFLUX is a new force field that combines the accuracy of quantum mechanics with the speed of force fields, without any link to the architecture of classical force fields. This force field is atom‐focused and adopts the parameter‐free topological atom from Quantum Chemical Topology (QCT). FFLUX uses Gaussian Process Regression (GPR) (aka kriging) models to make predicƟons of atomic properties, which in this work are atomic energies according to QCT’s InteracƟng Quantum Atom (IQA) approach. Here we report the adaptive sampling technique Maximum Expected Prediction Error (MEPE) to create data‐compact, efficient and accurate kriging models (sub kJ mol‐1 for water, ammonia, methane and methanol, and sub kcal mol‐1 for N‐methylacetamide (NMA)). The models cope with large molecular distortions and are ready for use in molecular simulation. A brand new press‐one‐buƩon Python pipeline, called ICHOR, carries out the training.

Published: June 2020

Translation of redox biocatalysis into a commercial H-Cube hydrogenation flow reactor was achieved using immobilized enzyme systems for biocatalytic hydrogenations. Carbon-supported enzymes for H2-driven NADH recycling and NADH-dependent C=O reductions were handled comparably to supported metal catalysts. High activity at room temperature with 2 bar H2 was attained, highlighting that biocatalytic strategies enable implementation of hydrogenation reactions under mild conditions. High conversions were achieved in short residence times (< 2 s), with high biocatalyst turnover frequencies (1,420 min-1) and space-time yields (7.9 kg L-1 h-1). These results represent the first example of direct biocatalytic hydrogenation in a commercial flow reactor.

Authors: Shaji Dr. Divya
Published: June 2020

COVID-19 which is caused by the virus SARS-CoV-2, has now been declared a global pandemic by the World Health Organization. At present, no specific vaccines or drugs are available to treat COVID-19. Therefore, there is an urgent need for the identification of novel drug lead compoundsto treat COVID-19. The SARS-CoV-2 main protease (Mpro also known as 3CLpro) and RNA-dependent RNA polymerase (RdRp also known as nsp12) are the best-characterized drug targets among corona viruses. In order to discover the natural lead compounds for SARS-CoV-2, weperformed molecular docking with the compounds from Moringa Oleifera that target the Mpro and RdRp. The molecular docking studies were carried out using AutoDock Vina through PyRx. Drug-likeness property of the selected compounds was checked by applying the ‘Lipinski’s rule of five’ using Swiss ADME. The top four compounds with most favourable binding affinity were selected for each of the targets. The results indicated that the compounds kaempferol, pterygospermin, morphine and quercetin exhibited best binding energy towards Mpro and RdRp. This study suggests that these natural compounds could be promising candidates for further evaluation of COVID-19 prevention.

Published: June 2020

Matrix-assisted laser desorption/ionisation mass spectrometry (MALDI-MS) is widely used for theanalysis of biomolecules. Label-assisted laser desorption/ionisation mass spectrometry (LALDI-MS) isa matrix-free variant of MALDI-MS, in which only analytes covalently attached to a laserdesorption/ionisation (LDI) enhancer are detected. LALDI-MS has shown promise in overcominglimitations of MALDI-MS in terms of sample preparation and MS analysis. In this work, we havedeveloped water-soluble pyrene-based LDI reagents (LALDI tags) that can be used for (in situ) labellingand LALDI-MS analysis of reducing carbohydrates from complex (biological) samples without the needfor additional chemical derivatisation or purification. We have systematically explored the suitabilityof four pyrene-based LDI enhancers and three aldehyde-reactive handles, optimised samplepreparation, and exemplified the use of a LALDI tag by the detection of lactose in cow’s milk. Theseresults demonstrate that LALDI-MS is a promising technique for the analysis of reducing carbohydratesin biological samples, and pave the way for the development of LALDI-MS for glycomics anddiagnostics.
Triple, Mutually Orthogonal Cycloadditions Through the Design of Electronically Activated SNO-OCTs
Authors: Hu Yun , Roberts Jessica M. , Kilgore Henry R. , Lani Amirah Mat , Raines Ronald , Schomaker Jennifer
Published: June 2020

Interest in mutually exclusive pairs of bioorthogonal labeling reagents continues to drive the design of new compounds capable of fast and predictable reactions. The ability to easily modify heterocyclic strained cyclooctynes containing sulfamate backbones (SNO-OCTs) enables electronic tuning of the relative rates of reactions of SNO-OCTs in cycloadditions with Type I–III dipoles. As opposed to optimizations based on just one specific dipole class, the electrophilicity of the alkynes in SNO-OCTs can be manipulated to achieve divergent reactivities and furnish mutually orthogonal dual ligation systems. Significant rate enhancements for reactions of a difluorinated SNO-OCT derivative compared to the parent scaffold were noted, with the second-order rate constant in cycloadditions with diazoacetamides exceeding 1 M−1 s −1 . Computational and experimental studies were employed to inform the design of triple ligation systems that encompass three orthogonal reactivities. Finally, polar SNO-OCTs are rapidly internalized by mammalian cells and remain functional in the cytosol for live-cell labeling, highlighting their potential for diverse in vitro and in vivo applications.

Teachers’ Opinions about the Effect of Chemistry Demonstrations on Students’ Interest and Chemistry Knowledge
Authors: Vinko Luka , Delaney Seamus , Devetak Iztok
Published: June 2020

Chemistry is an experimental discipline that uses experimentation as one of its most important research methods. Laboratory work and other practical work are therefore also essential in chemistry lessons. Chemistry demonstrations are used by teachers as an educational approach that can increase students’ interest in chemistry and motivate them to learn chemical concepts with understanding. However, if the students are actively involved in the chemistry demonstration, it can be just as effective as or even more effective than students’ learning through experiments. The purpose of this research is to examine teachers’ opinions about the impact of chemistry demonstrations on students’ interest and chemistry knowledge. Based on a quantitative research approach, 81 primary and secondary school teachers from different regions of Slovenia participated in this study. Participating teachers completed an online questionnaire on their perceptions of the impact of chemistry demonstrations on students’ interest and performance in chemistry classes and on the quality of students’ knowledge of chemistry. The results show that regardless of the years of teaching experience and the frequency of performing chemistry demonstrations, the participating teachers consider such demonstrations to have a positive effect on the motivation and performance of the students in chemistry and on the quality of the students’ knowledge of chemistry.

Novel Techniques for Built-Up Area Extraction from Polarimetric SAR Images
Authors: Ratha D , Gamba P , Bhattacharya A , Frery Alejandro
Published: June 2020

© 2004-2012 IEEE. Built-up (BU) area extraction from remote sensing images is important to monitor and manage urbanization and industrialization. In this letter, we propose two BU area extraction techniques based on the analysis of fully polarimetric synthetic aperture radar (PolSAR) data. Both methods exploit the geodesic distance on the unit sphere in the space of Kennaugh matrices. The first method is based on the three dominant scattering types in the scene and compares them with scattering models; if any of them matches with BU type elementary scattering models, then the pixel is said to belong to a BU area. The second method is based on a novel PolSAR BU index (RBUI) composed by considering scattering mechanisms from BU structures. The two proposed techniques are validated on two different urban scenes, one acquired at C-band by RADARSAT-2 and other at L-band by ALOS-2 SAR sensors.

Assessing the Association between Agile Maturity Model Levels and Perceived Project Success
Authors: Henriques Vaughan , Tanner Maureen
Published: June 2020

Aim/Purpose: Given the underlying philosophy of the agile manifesto, this study investigates whether an increase in agile maturity is associated with improved perceived project success.

Background: The underlying philosophy of the agile manifesto is embodied in principle one which promotes the continuous delivery of software that is deemed valuable by the customer, while principle twelve encourages continual improvement of the delivery process. This constant improvement, or maturity, is not a concept unique to agile methods and is commonly referred to as a maturity model. The most common of maturity model is the Capability Maturity Model Integrated (CMMI). However, research consensus indicates CMMI might not fully be compatible with agile implementation, specifically at higher levels of maturity without sacrificing agility. Agile maturity models (AMM), which are aligned to agile principles encourage continuous improvement while maintaining agility.

Methodology: The study employs a conceptual model based on an existing agile maturity model that is related to perceived project success. Using an objectivist perspective, a quantitative method was employed to analyze the results of an online survey of agile practitioners.

Contribution: The significant contribution from this research is the validation of the conceptual model relating the activities and maturity levels of the AMM as the independent variables to the dependent variable of perceived project success.

Findings: The data analysis found that a significant positive correlation exists between maturity levels and perceived project success. The strongest correlation was found at the highest maturity level, with relatively weaker correlation at the lower levels of maturity. It can thus be concluded that a higher level of maturity in the AMM is positively associated with perceived project success.

Recommendations for Practitioners: The study has practical implications in highlighting that performance management, requirements management, regular delivery and customer availability are key areas to focus on to establish and continually improve the success of agile implementations. This study further assists practitioners in systematically identifying the critical agile activities, such as the use of story cards, continuous delivery and the presence of a knowledgeable customer.

Recommendation for Researchers: The contributions of this study for academics is the confirmation of the maturity model developed by Patel and Ramachandran (2009a). This study also shows the association between the individual activities within the maturity levels as well as the maturity levels and the perceived project success, addressing a gap in literature relating these concepts.

Future Research: It would be useful to replicate this study whilst following a qualitative approach. The study could also be replicated with a sample consisting of agile project customers.

Published: June 2020

Aim/Purpose: In this paper the authors explore and analyse the literature to determine the common reasons why a student may choose to plagiarise. The predominant purpose of the research formed part of a larger study to develop metrics and methods to identify potential plagiarism within coding-based assignments.

Methodology: A systematic literature review with the objective to identify and rank the most common reasons for plagiarism was conducted. This was achieved by identi-fying primary studies conducted on the reasons for plagiarism. The identified studies were subsequently subjected to a top down quality assessment with a number of criteria. In total, 37 studies made it through the selection process. The results of the selected studies were synthesized to obtain a ranked list of reasons why students plagiarise.

Contribution: This paper contributes a ranked list of reasons that may influence a student’s decision to plagiarise, based on a set of categories emerging from the literature.

Findings: Eleven possible categories indicating the common reasons behind a student’s decision to plagiarise are identified. The literature revealed that aspects such as the external values of the student and attitudes towards academia and teaching styles are significant factors that impact a student’s willingness and decision to plagiarise.

Impact on Society: Instructors may gain a better understanding on why their students decided to plagiarise.
Analysis of the Effect of MAG Welding Parameters on Microstructure and Mechanical Properties of TRIP 800 Steels with Finite Elements
Authors: ÇAKMAKKAYA Mehmet
Published: June 2020

In this study, MAG welding method was used. 2 mm thick TRIP 800 steel sheets are used in different welding parameters. Microstructures of welded joints were analyzed by taking OM (optical microscope) images from the main metal areas of the welding zone, HAZ (the region under the influence of heat). Depending on the welding parameters, (welding current: 40-50-60 Ampere, and welding speed: 5-7.5 mm/sn), ferritic, HAZ and martensitic phase regions were determined in microstructures in the main metal, HAZ and welding regions, respectively. The strengths of the welded connections were measured using the tensile test. Welding wire speed is chosen to obtain high penetration and ideal width welding seams. The strength of the welded bond using these parameters is determined as 1266 MPa as the highest value. It was determined that grain growth and martensitic phase transformations occur in fusion regions and result in brittle fracture. The Fusion zone and other regions were analyzed with finite elements.
Influence of VFR Tourism on the Quality of Life of the Resident Population
Authors: González Damián Alfonso , Macías Ramírez Alma Rosa
Published: June 2020

The aim of this document is to report on characteristics of VFR travel, the perceived impacts of these trips, and their effects on the quality of life of the resident community. Cozumel, an international insular tourist destination in Mexico, is taken as case of study. Data were obtained from a cross-sectional observational study, driven by survey conducted in Cozumel to characterize VFR trips, using an instrument that has been previously tested in other destinations and a composite scale was constructed to measure perceived quality of life by means of a survey administered to a sample of Cozumel residents. Structural equation models were used to test the influence of the social impacts perceived by the population on their quality of life. The movement of VFR travellers to Cozumel is significant, although their main expenses are not used in commercial accommodation. Community and economic impacts are perceived as significant by the population, whereas the impact on mobility and local transportation is perceived as negative. The direct and positive influence of economic benefits on the quality of life of local population was significant, whereas community-related and transportation-related impacts were significant only for residents who were not visited by friends or relatives. The main implications of these findings lead to the need to examine, in greater detail, the quality of life of residents in tourism destinations receiving VFR travelers. Thus, the main contribution of this paper, is to figure out that it is not the same to receive visitors than to observe others receiving them, not just in economic terms, but in terms of emotional and community well-being. This contrast is very likely to be confirmed in studies carried out in other international tourism destinations around the world.
Market Segmentation in Urban Tourism: Exploring the Influence of Personal Factors on Tourists' Perception
Authors: Chebli Amina , Chabou Othmani Meriem , Ben Said Foued
Published: June 2020

A statistical analysis based on a tripartite theoretical model of tourist attraction was conducted in this work to examine the influence of personal factors on tourists’ perception of the attractions that determine a city's attractiveness. Using the responses of a sample of 510 international tourists, a random sample of 171 was selected, from which parametric and non-parametric tests were carried out: Levene’s test, Kruskal-Wallis test and Mann-Whitney test. The results show that, from a statistical point of view, there are statistically significant relationships between tourist perception and personal factors. This reveals that the same tourist attractions can be perceived and evaluated differently according to gender, age, motivation, and region of origin. Thus, there is a significant influence of internal factors on the tourists’ perception. Tourism perception is therefore not static but fluctuating. Consequently, it is imperative for decision-makers to segment the tourism market to satisfy tourists, meet their expectations, and enhance the attractiveness of a destination. The main results of this research are related to the contrasting perceptions of the same tourist attraction by different groups of tourists. An exploration that has so far not been carried out in previous research, in the context of urban tourism. Thus, tourism managers should take this variation into account when planning a tourism marketing and communication strategy. Research proves that targeted and focused tourist development can increase the tourist attractiveness of a city, the level of which depends crucially on perception. Finally, a presentation of four models that categorize and prioritize tourist attractions according to preferences by age, gender, motivation, and original destination is presented. These models are put forward as a referential, decision-support framework that clarifies the nuanced preferences of different tourist groups. The theoretical and marketing implications are also discussed for further research and development of tourism destination management.

Bu çalışmada, AISI H11 sıcak iş takım çeliğinin tornalanmasında kriyojenik işlemin kesici takım performansı üzerine etkileri araştırılmıştır. Deneylerde TiAlN+TiN kaplı tungsten karbür takımlar kullanılmıştır. Kesici takımlar üzerine 6 saat süre ile -80 °C’de sığ kriyojenik işlem (SCT6), 6 saat süre ile -196 °C’de derin kriyojenik işlem (DCT6) ve 24 saat süre ile -196 °C’de derin kriyojenik işlem (DCT24) uygulanmıştır. Tornalama deneyleri 0,6 mm kesme derinliği, 0,18 mm/dev ilerleme hızı ve 320, 360, 400 ve 440 m/dak olmak üzere dört farklı kesme hızında gerçekleştirilmiştir. Deneysel sonuçlar kriyojenik işlemin kesici takımın aşınma direncini artırdığını göstermiştir. En düşük kesici takım aşınması ve yüzey pürüzlülüğü değerleri DCT24 takımla elde edilmiştir. Yanak aşınmasında %13-28 oranlarda, yüzey pürüzlülüğünde ise %7-14 oranlarda iyileşmeler gözlenmiştir. Diğer yandan kriyojenik işlemin kesici takımların sertliğinde %4,4-8,7 oranlarda artış sağladığı tespit edilmiştir. En yüksek sertlik artışı da DCT24 takımda meydana gelmiştir.

En México, el cultivo de cítricos tiene una importancia alimentaria, social y cultural que llega a regir la vida familiar y la dinámica comunitaria en las regiones y están siendo afectadas por el cambio climático. El objetivo de esta investigación fue medir la percepción de los citricultores, ante el efecto del cambio climático. Se aplicó una encuesta participativa a 65 productores de cítricos de Campeche, México. Se midieron variables sobre ocurrencia de eventos asociados al cambio climático, daño directo a las plantas, percepción del aumento de fenómenos meteorológicos, cambio tecnológico y socioeconómico. Los encuestados son hombres (86.3%), de edad mayor y escolaridad básica. El 55% de los participantes posee tierra ejidal y 44% propiedad privada. El rendimiento promedio de los cítricos es bajo debido a la falta de sistemas de riego tecnificado y a los efectos del cambio climático, particularmente el aumento de la temperatura y el descenso de la precipitación. Los productores poseen un total de siete tipos de cultivos en sus parcelas, sin correlación con el tamaño de propiedad (r= 0.032), ni con el área destinada al cultivo (r= 0.33). El 66.6% de los participantes ha escuchado sobre el cambio climático siendo la fuente de información la televisión. El 69.6% ha percibido cambios mayores en el clima, lo que ha motivado a realizar cambios en el tipo de labranza (McNemar.test χ2= 10.56, p< 0.01**). Así, los efectos del cambio climático están incidiendo en las prácticas de manejo de los cítricos en Campeche; sin embargo, son acciones reactivas y se requieren de investigaciones que cuantifiquen y valoren los daños por este fenómeno y se diseñen estrategias para contrarrestar sus efectos en el mediano y largo plazo.

La uchuva (Physalis peruviana L.) es una solanácea susceptible a enfermedades del suelo, por esa razón se propone su cultivo en México bajo invernadero e hidroponía. Es necesario, determinar su respuesta a la conductividad eléctrica de la solución nutritiva (CE), razón por la cual se expuso a las plantas a 1, 2 y 3 dS m-1. La luz solar es otro factor que incide en la calidad de los frutos, por lo cual se cosecharon frutos del interior y exterior del dosel vegetal. También se determinó el efecto de la madurez del fruto. A los frutos se les determinó peso, Brix, firmeza y color (L, a y b). La CE, ubicación en dosel y madurez de frutos generaron 12 tratamientos. Los datos se compararon con prueba de medias de rangos. De los frutos, la CE de la solución nutritiva afectó la firmeza y los Brix excepto el peso. La posición de los frutos en el dosel vegetal tampoco afectó estas variables. La madurez a la cosecha afectó la calidad de los frutos. Los frutos cosechados 30 días después de madurez comercial perdieron peso y firmeza, y aumentaron Brix en frutos más maduros. La ubicación del fruto y madurez no afectaron el color en fruto.

La producción de plántulas de calidad es primordial para que durante el trasplante se propicie un crecimiento óptimo y buenos rendimientos del cultivo; por ello, el objetivo de la presente investigación fue determinar el efecto de bacterias promotoras de crecimiento vegetal y el manejo de la nutrición en la fisiología y crecimiento de plántulas de chile serrano. En condiciones de invernadero se llevó a cabo un experimento, con chile serrano var. Tampiqueña 74, bajo un diseño completamente al azar con arreglo factorial de 2×2×2. Los factores fueron: inoculación (con o sin Pseudomonas tolaasii), sustrato (con y sin esterilizar), y solución nutritiva (Steiner y té de vermicompost) con un total de ocho tratamientos con cuatro repeticiones cada uno. Los resultados indican que el efecto de P. tolaasii es altamente significativo en sustrato no esterilizado y con solución Steiner, donde las plántulas presentaron mayor altura, diámetro del tallo, área foliar, y la biomasa seca de parte aérea. Además, aumentó la concentración de NO3 en savia. Con el té de vermicompost la inoculación solo impactó en la longitud y volumen radical; mientras que con la solución Steiner únicamente tuvo efecto en el contenido nutritivo de N y K+ e índices de crecimiento. La inoculación de P. tolaasii en plántulas de chile serrano favorece la fisiología y concentración nutritiva siempre y cuando no se esterilice el sustrato. El menor efecto sobre las plántulas ocurre si sólo se suministra té de vermicompost.
El oxígeno en la zona radical y su efecto en las plantas

La información presentada analiza el estado del arte de las evidencias en los últimos 20 años de la importancia y los efectos de la disponibilidad de oxígeno en la rizósfera sobre el crecimiento y desarrollo de las plantas. Las condiciones adversas de factores bióticos (microrganismos) y abióticos (temperatura, anegamiento, salinidad, otros) que influyen en la concentración de oxígeno en la rizósfera, pueden conducir a una caída rápida en los niveles de oxígeno y afectar la morfología, metabolismo y fisiología de las raíces, con un efecto negativo sobre el crecimiento de la planta. Las técnicas de oxigenación en el medio radical pueden ser favorables, tanto en suelos como en sustratos, en situaciones donde existe un riesgo de hipoxia, pero se requieren estudios específicos sobre el efecto de la aplicación de oxígeno en cada especie, así como la medición de las respuestas para identificar los requerimientos de oxígeno que maximicen el rendimiento y la calidad de los productos cosechados, tanto en campo como en invernadero. En el sector agrícola, se requieren técnicas que sean sustentable y económicamente viables aun con los altos costos que implica el uso de las nuevas tecnologías.

En la región de Huatusco, Veracruz se realizó un experimento para comprobar el efecto que tiene el uso adecuado de fertilizante en la producción de café bajo sombra de especies arbóreas fijadoras de nitrógeno. Para ello, se plantearon cuatro tratamientos en cuatro sistemas agroforestales (café-Inga vera, café-Juglans pyriformis, café-Erythrina poeppigiana y café-E. poeppigiana-Grevillea robusta), con tres bloques de 10 plantas cada uno, los cuales consistieron en: a) sin fertilización; b) fertilización al suelo; c) fertilización foliar; d) fertilización al suelo y foliar. El balance nutrimental se evaluó mediante dos análisis foliares realizados antes y después de la fertilización. El rendimiento se evaluó durante los meses de noviembre y diciembre. Con el manejo nutrimental propuesto se elevaron las concentraciones de N, P, K, Ca, Mg y Mn, mientras que disminuyeron las de Fe, Cu y Zn, acercándose a los niveles óptimos para el cultivo. No se encontraron diferencias significativas (p≤ 0.05) en las concentraciones de nutrientes entre los cuatro tratamientos en los sistemas IV y EG. En EP, hubo diferencia para Ca y Mn, en los tratamientos 2 y 3. En JP hubo diferencia para Mg en los tres tratamientos.
