Millennial Tourists’ Environmentally Sustainable Behavior Towards a Natural Protected Area: An Integrative Framework
Authors: Sharmin Farzana , Sultan Mohammad Tipu , Badulescu Alina , Bac Dorin Paul , Li Benqian
Published: October 2020

In the last few years, natural protected areas have been facing great challenges and degradation around the world. Among this, environmental sustainability has become a priority to create harmony between tourists and nature. Tourists visiting protected areas are becoming progressively more concerned regarding the environment. Moreover, the United Nations (UN) “Sustainable Development Goals (SDGs)” have highlighted the potential role of young tourists to contribute to sustainable tourism. However, very few studies have focused on tourists’ environmentally sustainable behavior towards natural protected areas. To fill the existing gap in the literature, this study aims to provide a theoretical framework that includes environmental sustainability awareness (ESA) in measuring millennial tourists’ environmentally sustainable behavior (ESB). Thus, this study delivers an integrated approach based on the value-belief-norm (VBN) theory and the concept of the new ecological paradigm (NEP) towards protected areas. A self-administered questionnaire survey was conducted from one of the protected areas located in the north of Sichuan province of China, and 511 responses were obtained for statistical analysis. Results of the structural statistical analysis showed that the unified model includes a satisfactory level of predictive power for tourists’ ESB, which was superior to existing theories and concepts. The findings also revealed that all proposed relationships of the variables were significant and identified the positive influence of environmental sustainability awareness in generating the ESB. This study contributes towards sustainable tourism development and the conservation of protected areas, with several practical implications for local authorities in terms of millennial participation.

Published: October 2020

Hydrogen technologies are promising candidates of new energy technologies for electric power load smoothing. However, regardless of long-term public investment, hydrogen economy has not been realized. In Japan, the National Research and Development Institute of New Energy and Industrial Technology Development Organization (NEDO), a public research-funding agency, has invested more than 200 billion yen in the technical development of hydrogen-related technologies. However, hydrogen technologies such as fuel cell vehicles (FCVs) have not been disseminated yet. Continuous and strategic research and development (R&D) are needed, but there is a lack of expertise in this field. In this study, the transition of the budgetary allocations by NEDO were analyzed by classifying NEDO projects along the hydrogen supply chain and research stage. We found a different R&D focus in different periods. From 2004 to 2007, empirical research on fuel cells increased with the majority of research focusing on standardization. From 2008 to 2011, investment in basic research of fuel cells increased again, the research for verification of fuel cells continued, and no allocation for research on hydrogen production was confirmed. Thereafter, the investment trend did not change until around 2013, when practical application of household fuel cells (ENE-FARM) started selling in 2009, in terms of hydrogen supply chain. Hydrogen economy requires a different hydrogen supply infrastructure, that is, an existing infrastructure of city gas for ENE-FARM and a dedicated infrastructure for FCVs (e.g., hydrogen stations). We discussed the possibility that structural inertia could prevent the transition to investing more in hydrogen infrastructure from hydrogen utilization technology. This work has significant implications for designing national research projects to realize hydrogen economy.
Determinants of Different Types of Positive Environmental Behaviors: An Analysis of Public and Private Sphere Actions
Authors: Hansmann Ralph , Binder Claudia R.
Published: October 2020

A survey of 1206 participants investigated determinants of positive environmental behaviors (PEBs) in Switzerland. Based on a principle component analysis on data for 23 different PEBs, three behavior types were distinguished: (i) public sphere PEBs with politically mediated impacts; (ii) socially salient private “lighthouse” PEBs that convey a pro-environmental message; and (iii) less socially salient private PEBs. An environmental behavior model identified general environmental knowledge and attitudes as the strongest predictors of PEBs, followed by green self-identity, justifications, assumed consequences, prescriptive social norms, gender, age, and perceived behavioral control (PBC), respectively. To promote sustainability-oriented behaviors and achieve corresponding societal and economic changes, the identified psychological factors need to be promoted by education and communication strategies as well as complementary measures ranging from policy changes to technology development and systems design. Green self-identity turned out to be significantly more influential for private PEBs than for public sphere PEBs, whereas prescriptive social norms and environmental knowledge were more important for public sphere PEBs. These findings indicate that promoting different types of sustainability-oriented behaviors may require distinct strategies. Public sphere PEBs may be enhanced well by conveying social practices and norms, whereas the promotion of a pro-environmental green self-identity may increase private sphere PEBs effectively.

Published: October 2020

Rapid global urbanization has caused substantial changes in land cover and vegetation growth. Rapid urban growth in a short time has escalated the conflicts between economic development and ecological conservation, particularly in some metropolitan regions. However, the effects of rapid urbanization on vegetation have not been fully captured, especially accounting for the latest ecological development initiatives. In this study, we chose a typical urban agglomeration, the Beijing–Tianjin–Hebei (BTH) urban agglomeration in China, and analyzed the vegetation variation and the impacts of urbanization on the vegetation growth based on transferable methods, using data such as the Normalized Difference Vegetation Index (NDVI) and the nighttime light (NTL). The results indicate significantly enhanced vegetation growth in the BTH region, with a strikingly spatial pattern of greening in the northwest, and browning in the southeast from 2001 to 2018. Besides this, the results enclose most of the areas (72%) of built-up land in the BTH, which tended to brown in the process of rapid urban development, while 27% greened with increasing urbanization. This means that the vegetation’s response to urbanization shows apparent differences and geographic heterogeneity along the urbanization gradient at the urban agglomeration scale. Parts of the periphery of the metropolis and the central areas of developing cities may experience a browning trend; however, the core urban areas of urbanized metropolises demonstrate greening, rather than browning. Furthermore, this study provides solid evidence on the remarkable greening impacts of several ecological restoration projects which are currently underway, especially in ecologically fragile areas (e.g., the suburbs). The implications derived from the urban ecological development and the transferable methodology deployed in this paper facilitate the unfolding relationships between urbanization and social-ecological development. Our findings provide new insights into the interactions between vegetation dynamics and urbanization at the regional level.
Evaluation of the Resilient Modulus of Hot-Mix Asphalt Made with Recycled Concrete Aggregates from Construction and Demolition Waste
Authors: Galan Juan J. , Silva Luís M. , Pasandín Ana R. , Pérez Ignacio
Published: October 2020

This paper reports the influence of the percentage of recycled aggregate (RCA) from construction and demolition waste (C&DW) together with the percentage of binder (L), curing time (t) and temperature (T) of the samples on the stiffness of a hot asphalt mixture. The study was carried out using the response surface methodology (RSM). The resilient modulus was chosen to estimate the stiffness of the mixture. The percentages of RCA studied were 0% (control), 5%, 10%, 20% and 30%, whilst 3.5%, 4% and 4.5% were those chosen for the binder content. Before compacting the samples, they were left into the oven to cure. Curing time, or pretreatment time, were set at 0 (control), 2 and 4 h. The samples were subjected to temperatures of 0, 10 and 20 °C. The natural aggregate is of the hornfels type. All the specimens studied showed high stiffness at low temperatures. According to this research, temperature proved to be the most influential factor on the decrease in the resilient modulus and, conversely, the percentage of recycled aggregate is not a significant factor in the range of values studied.
How the ENGOs Can Fight the Industrial/Business Lobby with Their Tools from Their Own Field? ENGOs Participation in Emissions Trading Market
Authors: Asproudis Elias , Weyman-Jones Thomas
Published: October 2020

In this article, we explain how several environmental groups are attempting to influence environmental policy by changing the total amount of pollution allowed within the tradable emissions market. We highlight the case where environmental groups may participate in strategic behaviour to resemble co-operative coalition behaviour. We present an interesting way that environmental groups can encourage their goal of reducing pollution, contrary to the industrial/business groups’ desires. This is a major concern in our world, and such a new approach could be adopted more broadly.

Published: October 2020

Human health is a key pillar of modern conceptions of sustainability. Humanity pays a considerable price for its dependence on fossil-fueled energy systems, which must be addressed for sustainable urban development. Public hospitals are focal points for communities and have an opportunity to lead the transition to renewable energy. We have reimagined the healthcare energy ecosystem with sustainable technologies to transform hospitals into networked clean energy hubs. In this concept design, hydrogen is used to couple energy with other on-site medical resource demands, and vanadium flow battery technology is used to engage the public with energy systems. This multi-generation system would reduce harmful emissions while providing reliable services, tackling the linked issues of human and environmental health.
Biological Waste Air and Waste Gas Treatment: Overview, Challenges, Operational Efficiency, and Current Trends
Authors: Dobslaw Daniel , Ortlinghaus Oliver
Published: October 2020

International contracts to restrict emissions of climate-relevant gases, and thus global warming, also require a critical reconsideration of technologies for treating municipal, commercial, industrial, and agricultural waste gas emissions. A change from energy- and resource-intensive technologies, such as thermal post-combustion and adsorption, as well to low-emission technologies with high energy and resource efficiency, becomes mandatory. Biological processes already meet these requirements, but show restrictions in case of treatment of complex volatile organic compound (VOC) mixtures and space demand. Innovative approaches combining advanced oxidation and biofiltration processes seem to be a solution. In this review, biological processes, both as stand-alone technology and in combination with advanced oxidation processes, were critically evaluated in regard to technical, economical, and climate policy aspects, as well as present limitations and corresponding solutions to overcome these restrictions.
Evolution of Waste Cooking Oil Collection in an Area with Long-Standing Waste Management Problems
Authors: De Feo Giovanni , Di Domenico Aurelio , Ferrara Carmen , Abate Salvatore , Sesti Osseo Libero
Published: October 2020

Waste cooking oil (WCO) can be a useful secondary raw material, if properly managed. On the contrary, uncontrolled disposal generates negative environmental impacts as well as economic loss. Therefore, improving WCO recovery rate, with the cooperation of citizens and effective collection programs, is fundamental. The aim of the study was to investigate the reason for the low recovery of WCO in those areas suffering serious waste management problems such as the Campania region in Southern Italy. For this purpose, the case of a WCO collection program adopted in Angri, a town of around 34,000 people with a high population density, was studied. In 2015, the collection program was managed by a social cooperative, while, in 2016, after the change of the local government, the collection of WCO was entrusted to a private company. In 2015, the households’ participation in the collection program was surveyed through a structured questionnaire. The results revealed that the collection of WCO was practiced by 53% of the respondents. Among those not collecting WCO, 76% of the sample wrongly disposed of WCO in their home (kitchen or toilet). Misinformation was the main reason why they did not adhere to the collection program. Therefore, it was suggested to support information and environmental education campaigns to promote environmental awareness of citizens. Unfortunately, the change of management, together with serious problems in the collection of municipal waste in the whole region, due to the continuous closures of the mechanical and biological plants, produced a sharp decline in the collection from 7730 kg in 2015 to an average of 3800 kg for the period 2016–2019, with a loss of more than 15,000 kg of WCO wrongly disposed with consequent environmental and economic damage. Therefore, information and awareness campaigns are important but the form of entrusting the collection service is equally important, especially in areas with long-standing waste management problems.
The Water-Energy-Food Nexus as an Adaptation Strategy for Achieving Sustainable Livelihoods at a Local Level

Published: October 2020

The imbalance between resource availability and population increase requires transformative approaches to inform policy, decision-making and practice on coherent adaptation strategies for improved livelihoods and resilient communities. Nexus approaches are built on an understanding that natural processes do not operate in isolation within a system; hence, an emergent challenge in one unit obviously disturbs the whole system. This study applied an integrated water-energy-food (WEF) nexus analytical model to holistically assess resource availability, distribution, use and management at a local level in Sakhisizwe Local Municipality, South Africa. The aim was to inform strategies and guidelines on improving livelihoods of resource-poor rural communities. The calculated municipal composite index of 0.185, coupled with a deformed spider graph, represents a marginally sustainable resource management result. The analysis simplified the relationship between the intricately interlinked socio-ecological components and facilitated the identification of priority areas for intervention. The process provides pathways that steer resource use efficiencies and attainment of Sustainable Development Goals (SDGs). Unlike current linear approaches, integrated and transformative approaches like the WEF nexus provide a multidisciplinary platform for stakeholder engagement to sustainably enhance cross-sectoral coordination of resource management and harmonisation of policies and strategies. The WEF nexus approach is useful for informing decisions on improving livelihoods, enhancing resource securities, identifying priority areas for intervention and providing transformative pathways towards sustainable development.
Xanthohumol and Gossypol Are Promising Inhibitors against Babesia microti by In Vitro Culture via High-Throughput Screening of 133 Natural Products

Published: October 2020

Human babesiosis caused by Babesia microti is an emerging threat for severe illness and even death, with an increasing impact worldwide. Currently, the regimen of atovaquone and azithromycin is considered as the standard therapy for treating human babesiosis, which, however, may result in drug resistance and relapse, suggesting the necessity of developing new drugs to control B. microti. In this regard, natural products are promising candidates for drug design against B. microti due to their active therapeutic efficacy, lower toxicity, and fewer adverse reactions to host. Here, the potential inhibitors against B. microti were preliminarily screened from 133 natural products, and 47 of them were selected for further screening. Gossypol (Gp) and xanthohumol (Xn) were finally shown to effectively inhibit the growth of B. microti with IC50 values of 8.47 μm and 21.40 μm, respectively. The cytotoxicity results showed that Gp and Xn were non-toxic to erythrocytes at a concentration below 100 μm. Furthermore, both of them were confirmed to be non-toxic to different types of cells in previous studies. Our findings suggest the potential of Gp and Xn as effective drugs against B. microti infection.

Background: Central serous chorioretinopathy (CSCR) is a chorioretinal disease affecting mostly middle age males. It is marked by the serous detachment of the neurosensory layer at the macula. This review of the literature provides a framework of the current characteristic/relevant imaging findings of CSCR. Although the pathogenesis of CSCR is unclear, the choroid plays a major role and its changes are fundamental to the diagnosis and treatment of CSCR. Methods: A systematic literature search focusing on current multimodal imaging for CSCR was performed. Only articles reporting on original clinical data were selected, studies in a language other than English were included only if an English abstract was provided. Additional sources included articles cited in the references list of the first selected articles. We deduced imaging findings based on current and relevant literature on the topic. Results: We found that sub foveal choroidal thickness (SFCT) and choroidal vascularity index (CVI) were greater in eyes with acute CSCR than in eyes with chronic CSCR or normal eyes. There was increased choroidal thickness (CT) in the macula compared to peripapillary region. In healthy eyes, the highest CVI was found in the nasal region followed by the inferior, temporal, and superior quadrant. The area with the least CVI was the macula. In eyes with CSCR, 100% had asymmetric dominant vortex veins compared to 38% in normal eyes. Conclusion: Choroidal imaging has advanced the diagnosis of CSCR. This has led to numerous imaging biomarkers like CVI, CT, and hyper-reflective dots for early detection and possible prognostication of CSCR. More techniques like wide field scans and en face imaging are being employed to characterize the choroid in CSCR.

Authors: Noura Nassim , Boulon Loïc , Jemeï Samir
Published: October 2020

To cope with the new transportation challenges and to ensure the safety and durability of electric vehicles and hybrid electric vehicles, high performance and reliable battery health management systems are required. The Battery State of Health (SOH) provides critical information about its performances, its lifetime and allows a better energy management in hybrid systems. Several research studies have provided different methods that estimate the battery SOH. Yet, not all these methods meet the requirement of automotive real-time applications. The real time estimation of battery SOH is important regarding battery fault diagnosis. Moreover, being able to estimate the SOH in real time ensure an accurate State of Charge and State of Power estimation for the battery, which are critical states in hybrid applications. This study provides a review of the main battery SOH estimation methods, enlightening their main advantages and pointing out their limitations in terms of real time automotive compatibility and especially hybrid electric applications. Experimental validation of an online and on-board suited SOH estimation method using model-based adaptive filtering is conducted to demonstrate its real-time feasibility and accuracy.
Results of sea level studies at RSHU

Published: October 2020

Study of sea level is being developed at RSHU in several directions: global, regional and local. The global one includes the study of the patterns of interannual fluctuations of the global sea level (GLS), identification of their genesis and development of a set of methods for its long-term forecast. Two approaches to the genesis of GLS are considered. In foreign studies, changes in GLS are determined by changes in the water mass of various cryosphere components, land water reserves and steric level fluctuations. Another approach, implemented at RSHU, is to assess contributions of various factors using the equation of the freshwater balance of the World Ocean as the sum of eustatic and steric factors. A physical-statistical method for two-decade GLS forecasting, based on delay in the GLS response to air temperature over the ocean, has been developed, as well as the GLS projections at the end of the century for climatic scenarios according to the CMIP5 project have been provided. In the regional context, the main attention is paid to identifying the genesis of the interannual variability of the Caspian Sea level with the aim of its long-term forecasting. The entire chain of cause-and-effect relationships in the North Atlantic-atmosphere-Volga basin-Caspian level system is discussed. It has been established that, as a result of the intensification of cyclonic activity in the North Atlantic, especially in the Norwegian Sea, caused by the processes of large-scale interaction between the ocean and the atmosphere,
there is an increase in evaporation and in the zonal transfer of water vapour to Europe and then to the Volga basin. Therefore, more precipitation falls in the runoff-forming zone of the basin, the annual runoff of the Volga and the level of the Caspian Sea increasing. The reverse is observed with weakening of cyclonic activity in the North Atlantic. In view of this, the level of the Caspian Sea is an integral indicator of largescale moisture exchange in the ocean-atmosphere-land system. The article discusses the features of interannual sea level fluctuations in Kronstadt since 1836. A simple two-parameter model for forecasting sea level by the end of the 21st century is proposed for major climate scenarios, the predictors being the GSL and the North Atlantic Oscillation. According to the most realistic forecast, the level in Kronstadt may rise to 34-59 cm (Baltic system) by the end of the century, while according to the “pessimistic” one — to 80-90 cm (Baltic system). The estimates of the extreme storm surge at which the level rise north of the Gorskaya can reach 600 cm (Baltic system) are given. The effect of flooding from storm surges is especially strong near Sestroretsk. The total area of possible flooding of the Kurortny district at a 4-m high surge wave exceeds 1260 hectares, all the beaches being completely lost. The trajectories of flood cyclones and their role for periods of climate warming and cooling are considered
Avaliação de processos naturais de salinização de águas subterrâneas na porção leste da bacia do rio Cachoeira, Bahia

Published: October 2020

Parcela significativa do nordeste brasileiro se notabiliza pela escassez hídrica, que é responsável por implicações socioeconômicas locais negativas. Além do déficit hídrico, esta região é afetada pela salinização de águas subterrâneas, que contribui para a perda de potabilidade da água. Na bacia do rio Cachoeira, Estado da Bahia, situada no limite do semiárido nordestino, as águas subterrâneas possuem concentração de sais dissolvidos naturalmente elevados em razão das altas taxas de evapotranspiração e interação rocha-água. Para a avaliação quantitativa desses processos nas concentrações de sais totais dissolvidos, foram empregadas técnicas estatísticas e simulações geoquímicas. Na análise das Componentes Principais verificou-se que os Componentes Principais 1 (CP1) e 2 (CP2) respondem, respectivamente, por 82,89 e 13,68% da variância das amostras analisadas. Enquanto o CP1 é majoritariamente atribuído a variações na concentração do íon HCO3 - , o CP2 é atribuído a variações na concentração do íon Cl- . Verificou-se três diferentes tendências, que descrevem variações distintas do CP2 em função daquelas observadas para CP1, refletindo diferentes proporções na importância da evapotranspiração e interação rocha-água na salinidade. As simulações geoquímicas foram capazes de reproduzir as concentrações das amostras mais salinas, a partir da evaporação e de reações rocha-água. A maior parte das amostras de água subterrânea agrupam-se ao longo da Tendência 3, cujo incremento de sólidos totais dissolvidos é majoritariamente explicado pela interação rocha-água. Em oposição, as amostras de água das Tendências 1 e 2, menos frequentes, possuem sólidos totais dissolvidos majoritariamente provenientes da evaporação da água.

Background

The COVID-19 pandemic strained hospital resources in New York City, including those for providing dialysis. New York University Medical Center and affiliations, including New York City Health and Hospitals/Bellevue, developed a plan to offset the increased needs for KRT. We established acute peritoneal dialysis (PD) capability, as usual dialysis modalities were overwhelmed by COVID-19 AKI.

Methods

Observational study of patients requiring KRT admitted to Bellevue Hospital during the COVID surge. Bellevue Hospital is one of the largest public hospitals in the United States, providing medical care to an underserved population. There were substantial staff, supplies, and equipment shortages. Adult patients admitted with AKI who required KRT were considered for PD. We rapidly established an acute PD program. A surgery team placed catheters at the bedside in the intensive care unit; a nephrology team delivered treatment. We provided an alternative to hemodialysis and continuous venovenous hemofiltration for treating patients in the intensive–care unit, demonstrating efficacy with outcomes comparable to standard care.

Results

From April 8, 2020 to May 8, 2020, 39 catheters were placed into ten women and 29 men. By June 10, 39% of the patients started on PD recovered kidney function (average ages 56 years for men and 59.5 years for women); men and women who expired were an average 71.8 and 66.2 years old. No episodes of peritonitis were observed; there were nine incidents of minor leaking. Some patients were treated while ventilated in the prone position.

Conclusions

Demand compelled us to utilize acute PD during the COVID-19 pandemic. Our experience is one of the largest recently reported in the United States of which we are aware. Acute PD provided lifesaving care to acutely ill patients when expanding current resources was impossible. Our experience may help other programs to avoid rationing dialysis treatments in health crises.

Published: October 2020

Artificial Intelligence and Deep Learning are good fields of research. Recently, the brother of Artificial Intelligence titled "Artificial Satisfaction" was introduced in literature [10]. In this article, we coin the term “Deep Loving”. After the publication of this article, "Deep Loving" will be considered as the friend of Deep Learning. Proposing a new field is different from proposing a new algorithm. In this paper, we strongly focus on defining and introducing "Deep Loving Field" to Research Scientists across the globe. The future of the "Deep Loving" field is predicted by showing few future opportunities in this new field. The definition of Deep Learning is shown followed by a literature review of the "Deep Loving" field. The World's First Deep Loving Algorithm (WFDLA) is designed and implemented in this work by adding Deep Loving concepts to Particle Swarm Optimization Algorithm. Results obtained by WFDLA are compared with the PSO algorithm.

Der gewerbliche Güterverkehr stellt urbane Agglomerationsräume vor umfangreiche Herausforderungen: Er verursacht Lärm und Schadstoffemissionen, beeinträchtigt die Verkehrssituation und blockiert städtischen Raum; E-Commerce und veränderte Lieferstrukturen des stationären Handels führen zu zusätzlichen logistischen Herausforderungen. Die Notwendigkeit, den innerstädtischen Verkehr zu entlasten und die durch Zustellverkehre induzierten Emissionen zu senken, erhöhen den Druck auf die KEP-Logistiker, ihre logischen Konzepte insbesondere in stark verdichteten Innenstadt- und Wohnlagen weiter zu optimieren. Darüber hinaus bestehen vielfältige Möglichkeiten, die durch den zunehmenden Onlinehandel induzierten Liefermengen durch Prozessoptimierungen an der Schnittstelle zwischen Kunde, Logistik und Onlinehandel zu konsolidieren und so Verkehrsaufkommen und verkehrsbedingte Emissionen zu reduzieren.

El gen Oly es una fuente de androesterilidad dominante que ha permitido conformar diversas poblaciones para realizar selección recurrente en trigo (Triticum aestivum L.), tal es el caso de la población androestéril de amplia base genética denominada PANDOLY.PABG, que ha permitido derivar líneas y generar variedades. Con el objetivo de estimar el avance genético después de 14 ciclos de selección recurrente en dicha población y valorar la eficiencia del gen Oly para formar líneas superiores, se evaluaron 80 líneas F5 tomadas al azar de los ciclos C0, C2, C4, C6, C8, C10, C12 y C14 más 10 variedades testigo. Se empleó un diseño alfa-látice 9 × 10 con dos repeticiones y dos fechas de siembra durante el ciclo otoño-invierno 2017/2018 en Roque, Guanajuato y Montecillo, Estado de México. Las variables evaluadas fueron días a floración (DF), altura de planta (AP), días a madurez (DM), rendimiento de grano (RG), tasa de llenado de grano (TLLG), índice de cosecha (IC), biomasa (BIO), peso de 1000 semillas (PMS), número de espigas por m2 (EPM2), de granos por m2 (GPM2) y de granos por espiga (GPE). El mayor aumento de RG fue de 1445 kg ha-1 entre los ciclos C0 y C2. El avance genético promedio en los 14 ciclos fue de 3.58 % (140.6 kg ha-1/ciclo). Entre los cambios morfofisiológicos destacan, particularmente en los ciclos avanzados de selección, aumento (P ≤ 0.05) en los caracteres TLLG, IC, BIO, PMS, EPM2, GPM2 y GPE, y disminución (P ≤ 0.05) de DF, DM y AP. Las variedades testigo y las líneas derivadas del C14 presentaron RG más altos (P ≤ 0.05) y estadísticamente iguales. El gen Oly es un excelente facilitador del mejoramiento genético poblacional en trigo.

El chile huacle (Capsicum annuum L.), ingrediente principal del mole, un platillo de importancia en la comida oaxaqueña y patrimonio cultural inmaterial de la humanidad, se encuentra en peligro de extinción, por lo que es necesario impulsar su cultivo mediante el mejoramiento de las prácticas de producción. La adición de NH4+ en la solución nutritiva incrementa el crecimiento y rendimiento de los cultivos, pero en concentración alta provoca toxicidad. El objetivo de este estudio fue evaluar el rendimiento y calidad de dos poblaciones de chile huacle (Rojo y Negro) y tres niveles de concentración de NH4+ (0, 1.5 y 3.0 meq L-1) en la solución nutritiva de Steiner, dando como resultado seis tratamientos, los cuales se evaluaron bajo un diseño completamente al azar con arreglo factorial de tratamientos 2 × 3 y 10 repeticiones; la unidad experimental fue un contenedor con 10 L de sustrato y una planta. Se detectaron diferencias significativas entre poblaciones en rendimiento y en número de frutos por planta. No hubo diferencias entre las concentraciones de NH4+ adicionadas a la solución nutritiva para ninguna de las variables evaluadas, ni en la interacción entre los factores de estudio, excepto para la combinación entre la población Negro cultivada y la concentración de NH4+ de 3.0 meq L-1, donde se obtuvo la mayor producción y número de frutos por planta.

Durante el manejo postcosecha del maíz (Zea mays L.) se presentan pérdidas importantes por el ataque de plagas de almacén, particularmente por gorgojo (Sitophilus zeamais Motschulsky). El objetivo del presente estudio fue evaluar la efectividad del epazote (Dysphania ambrosioides) para controlar los daños por gorgojo en maíz. Semillas de 11 genotipos de maíz, nueve experimentales y dos híbridos comerciales, todos con humedad de 13 % y sin daño físico que indicara la presencia de insectos, fueron sometidos a tratamientos con polvo de epazote en cuatro concentraciones (0, 5, 7 y 10 g de epazote kg-1 de semilla) para controlar gorgojo. Se utilizó un diseño completamente al azar con arreglo factorial y tres repeticiones. La unidad experimental consistió en una caja de plástico acondicionada donde se colocaron 100 semillas, previamente pesadas, junto con 50 gorgojos jóvenes y la dosis correspondiente de polvo de epazote. Las variables registradas fueron pérdida de peso, granos dañados y sobrevivencia de insectos, todos expresados en porcentaje. Hubo diferencias entre genotipos de maíz solamente para pérdida de peso (P ≤ 0.05); todos los genotipos de maíz registraron pérdidas; sin embargo, el híbrido CLTHW14001 fue el menos afectado con 3.5 % de pérdida de peso. Las dosis de 7 y 10 g de epazote kg-1 de semilla fueron sobresalientes en las variables pérdida de peso, granos dañados y sobrevivencia de insectos, con 3.4, 12.2 y 3.5 % en promedio, respectivamente. El híbrido CLTHW14001 mostró el menor daño con la dosis de 7 g de epazote kg-1 de semilla con 0.94 % de pérdida de peso. El uso de polvo de epazote para el control de gorgojo es efectivo en concentraciones desde 7 g kg-1 de semilla. El genotipo de maíz influye en la efectividad del tratamiento.

El psílido de la papa/tomate, Bactericera cockerelli, es una de las plagas más importantes de cultivos de solanáceas en el mundo. Spirotetramat y spiromesifen son insecticidas comúnmente utilizados contra esta plaga y actúan inhibiendo la acetil CoA carboxilasa, y con ello evitan la biosíntesis de lípidos. Se evaluó el efecto de los insecticidas sobre el comportamiento de oviposición de B. cockerelli en plantas de chile habanero [Capsicum chinense (Jacq)]. El follaje de la planta se dividió en tres estratos (superior, medio e inferior) y todas las combinaciones de estratos se trataron por separado con 30 mL de la solución a una concentración de 1 mL L-1 de formulación comercial, se utilizó una torre Potter a 0.703 kg cm-2 de presión, calibrada para aplicar 2 mL cm-2. Después de 1 h de tratamiento se retiró la cubierta plástica de los estratos no tratados, y las plantas de cada tratamiento se infestaron con 20 pares de adultos de 20 a 24 h y se les permitió ovipositar durante 7 d. Se registró el número de huevos por hoja por estrato y se calculó su porcentaje. El porcentaje de huevos por hoja en el testigo en los estratos superior, medio e inferior fue 42, 32 y 26 %, respectivamente. El Spiromesifen inhibió significativamente (P ≤ 0.05) la oviposición sólo en la capa tratada. El Spirotetramat redujo significativamente (P ≤ 0.05) la tasa de oviposición, independientemente del estrato tratado, lo que indica actividad biológica en partes no tratadas de la planta, ya sea por encima o por debajo de la parte tratada.
