Diagnosis and Recommendation Integrated System (DRIS) for pineapple (Ananas comosus), Honey Gold variety (MD-2)

1 recurso en línea (páginas 319-328).La piña (Ananas comosus), es la tercera especie tropical más importante, se cultiva en países tropicales y subtropicales, en ese orden de ideas y dada la importancia del cultivo, se hace necesario contar con una herramienta para un adecuado diagnóstico nutricional, es así como la presente investigación buscó determinar las normas DRIS (Sistema Integrado de Diagnóstico y Recomendación) para el cultivo de piña, esta es una metodología de interpretación de análisis foliares, basada principalmente en el establecimiento de poblaciones de referencia para la obtención de normas o relaciones ideales de nutrientes, las cuales sirven para la interpretación del contenido nutricional de una determinada especie. Se utilizó un diseño en bloques completos al azar, con seis tratamientos y cuatro repeticiones basados en diferentes planes de fertilización muestreando cuatros etapas del cultivo. Se usó un suelo con pH de 3. Los resultados mostraron deficiencias de B, S y Zn, elementos como el Cu y Na presentaron limitaciones por excesos seguido del Fe solo para la primera etapa y el P fue uno de los elementos minerales que presentó un equilibrio durante toda la etapa del cultivo. El orden decreciente de las limitantes por deficiencia para concentraciones en tejido foliar en piña se dividió en cuatro etapas de desarrollo del cultivo, la primera etapa de 3 meses después de la siembra, se encontró Mn>B>S>Ca>K>Mg>Cu>N>P>Zn> Na>Fe, la segunda etapa de 6 meses después de la siembra Zn>B>Na>Ca>Mn>Mg>K>N>P>S>Cu, la tercera etapa de 9 meses después de la siembra B>Zn>S>Mn>Ca>N>K>P>Mg>Na>Cu, y la última etapa de 12 meses después de la siembra B>Zn>Mn>Ca>Mg>N>K>S>Na>P>Cu.Pineapple (Ananas comosus) is the third most important tropical species and is grown in tropical and subtropical countries. Given the importance of this crop, it is necessary to have a tool for proper nutritional diagnosis. So, the present study sought to determine the DRIS (Integrated Diagnostic and Recommendation System) standards for the cultivation of pineapple, that is, a methodology for the interpretation of foliar analyzes, based mainly on the establishment of reference populations for obtaining norms or ideal relationships of nutrients, which serve for the interpretation of the nutritional content of a certain species. A randomized complete block design was used, with six treatments and four repetitions, based on different fertilization plans, sampling four stages of the crop. A soil with a pH of 3 was used. The results showed deficiencies of B, S and Zn; elements such as Cu and Na showed limitations as a result of excesses, followed by Fe, but only for the first stage, while P was one of the mineral elements that presented a good balance during the entire stage of the crop. The decreasing order of deficiency constraints for the leaf tissue concentrations in the pineapple was divided into four stages of crop development: the first stage 3 months after sowing: Mn>B>S>Ca>K>Mg>Cu>N>P>Zn>Na>Fe, the second stage 6 months after sowing: Zn>B>-Na>Ca>Mn>Mg>K>N>P>S>Cu, the third stage 9 months after sowing: B>Zn>S> Mn>Ca>N>K>P>Mg> Na>Cu, and the last stage 12 months after sowing: B>Zn>Mn>Ca>Mg>N> K>S>Na>P>Cu.Bibliografía y webgrafía: páginas 327-32

Estimating the global conservation status of more than 15,000 Amazonian tree species

Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict thatmost of the world’s >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació
