generación de servicios ecosistémicos, para priorizar la conservación y aportar de manera efectiva
a los instrumentos de planificación. Estas áreas son un elemento esencial en el espacio urbano
porque aportan servicios ecosistémicos, principalmente relacionados con la regulación del clima, el
ciclo del agua y la recreación. También, contribuyen a alcanzar los Objetivos de desarrollo
sostenible 11 y 15 al incentivar la trasformación de las áreas urbanas en espacios sostenibles,
inclusivos, seguros y resilientes. La investigación se desarrolló con una metodología flexible que
permite adaptarse a diferentes regiones, sirviendo como herramienta para los instrumentos de
planificación territorial. La metodología se basó en el análisis bibliométrico y la revisión sistemática
de literatura académica y gris, para identificar y evaluar con métodos estadísticos las variables
estratégicas territoriales (VTU) para la silvicultura urbana y los servicios ecosistémicos (SE)
relacionados con la cobertura arbórea. La investigación propuso criterios relevantes que permiten
tomar decisiones de planificación en cuanto a las áreas arbóreas, para caracterizarlas y clasificarlas
en categorías con el propósito de generar mayores servicios ecosistémicos urbanos. Se aplicaron
los criterios de clasificación al corredor del río Cali, que es uno de los sectores que tiene mayores
áreas con cobertura arbórea de la ciudad de Santiago de Cali, obteniendo como resultado que más
del 40% de las áreas con cobertura arbórea se clasifican como áreas para la recuperación. La
investigación concluyó que las áreas de menor extensión y distribuidas espacialmente en la periferia
del corredor del Río Cali son las que tienen mayor relevancia para la preservación. Siendo así, los
entes municipales deberían centrar la gestión en los espacios intervenidos y aledaños al río Cali,
para aumentar la cobertura arbórea que llevaría a la generación de más servicios ecosistémicos. (Texto tomado de la fuente)It is important to have criteria to classify areas with tree cover based on the generation of
ecosystem services, in order to prioritize conservation and contribute effectively to planning
instruments. These areas are an essential element in the urban space because they provide
ecosystem services, mainly related to climate regulation, the water cycle and recreation. They also
contribute to achieving Sustainable Development Goals 11 and 15 by encouraging the
transformation of urban areas into sustainable, inclusive, safe and resilient spaces. The research
was developed with a flexible methodology that can be adapted to different regions, serving as a
tool for territorial planning instruments. The methodology was based on bibliometric analysis and
systematic review of academic and grey literature, to identify and evaluate with statistical methods
the strategic territorial variables (VTU) for urban forestry and ecosystem services (ES) related to
tree cover. The research proposed relevant criteria that allow planning decisions to be made
regarding tree areas, to characterize them and classify them into categories with the purpose of
generating greater urban ecosystem services. The classification criteria were applied to the Cali
River corridor, which is one of the sectors with the largest areas with tree cover in the city of Santiago
de Cali, obtaining as a result that more than 40% of the areas with tree cover are classified as areas
for recovery. The research concluded that the areas of lesser extension and spatially distributed in
the periphery of the Cali River corridor are the most relevant for conservation. Thus, the municipal
entities should focus their efforts on the intervened areas adjacent to the Cali River in order to
increase tree cover, which would lead to the generation of more ecosystem services.MaestríaMagíster en Ingeniería - Ingeniería Ambiental. La investigación se desarrolló con una metodología flexible que
permite adaptarse a diferentes regiones, sirviendo como herramienta para los instrumentos de
planificación territorial. La metodología se basó en el análisis bibliométrico y la revisión sistemática
de literatura académica y gris, para identificar y evaluar con métodos estadísticos las variables
estratégicas territoriales (VTU) para la silvicultura urbana y los servicios ecosistémicos (SE)
relacionados con la cobertura arbórea.
• Etapa I denominada Alistamiento: Esta atapa abordó parcialmente los objetivos 1 y 2 logrando identificar las VTU y los SE asociados con las áreas urbanas y coberturas arbóreas. Se realizó a partir de la evaluación de la literatura temática académica y literatura gris por medio de análisis bibliométrico y revisión sistemática. Estos dos métodos se utilizaron para ampliar el rango de búsqueda evitando el sesgo de ubicación de los documentos y líneas de investigación.
Las VTU y los SE se identificaron a partir de la revisión uno a uno del material bibliográfico seleccionado.
• Etapa II denominada VTU: Esta etapa complementó el objetivo 1 logrando evaluar las VTU. Se realizó a partir del análisis de clúster jerárquico (dendrograma) determinado por la relación espacial de distancia entre la cobertura arbórea (censo arbóreo) y las VTU. Con este proceso se determinaron las Variables estratégicas Territoriales Urbanas (VeTU). Este método se utilizó para agilizar el procesamiento de los datos manteniendo la rigurosidad para obtener las variables estratégicas según la distancia a la cobertura arbórea.
Las VTU se evalúan a partir de la distancia a la cobertura arbórea identificada (individuo arboreo) en el censo. Las VeTU son las VTU que tienen menor distancia a la cobertura arbórea.
• Etapa III denominada SE: Esta etapa complementó el objetivo 2 logrando evaluar los SE. Se realizó a partir de la adaptación del cálculo del Índice de Servicios Ecosistémicos para Áreas Verdes (ISEAV) y árbol de decisión para estimar los indicadores e inferir los Servicios Ecosistémicos priorizados (SEp). Este método se utilizó para facilitar la toma de datos y agilizar el procesamiento de cada función ecosistémica.
Los SE se evaluaron a partir de calcular el Índice de Servicios Ecosistémicos para Áreas Verdes (ISEAV) obtenido de la digitalización y caracterización de las coberturas.
• Etapa IV denominada criterios de clasificación: Esta etapa abordó el objetivo 3 logrando relacionar los resultados de las etapas previas para finalmente proponer criterios de clasificación de las áreas urbanas con cobertura arbórea. Se realizó a partir de una matriz de relación de influencia de las VeTU y los SEp calificada por expertos (encuesta a expertos) para integrarla con los resultados previos. Este método se utilizó para abarcar diferentes enfoques profesionales y académicos que permitieran dilucidar las relaciones de influencia.
• Etapa V denominada caso de estudio: Esta etapa se aplicaron los criterios de clasificación al caso del corredor del río Cali.Planeación y desarrollo territorialIngeniería.Sede Palmir
Temporal analysis of cigarette butt accumulation on a touristic beach in Cartagena, Colombia
No full textContiene ilustraciones, gráficos.Cigarette butts (CBs) are among the most common types of litter found in coastal environments, including beach sand. They are considered hazardous waste due to their significant toxicity and the potential threats they pose to both ecosystems and public health. This study examines historical CB density data collected from Bocagrande Beach, Colombia, across two distinct periods: 2011–2015 and 2021–2022. It includes an assessment of variations in key pollution indexes, the Plastic Abundance Index (PAI), Clean Coast Index (CCI), Cigarette Butt Abundance Index (CBAI), and Cigarette Butts Pollution Index (CBPI). The methodology used visual identification surveys and the systematic collection of CBs and cigarette butt fibers (CBFs) within 500-m2 transects. A key finding of this research was the average solid waste density between 2011 and 2015 of 0.63 items/m2, with CBs being the most prevalent at 0.19 items/m2. Remarkably, an average of 0.6 CBs/m2 was observed in the 2021–2022 period, demonstrating an increasing trend in cigarette butt pollution. The CBPI values ranged from 2.28 to 31.16, classifying the beach from polluted to severely polluted conditions. © The Author(s) 2025.Sostenibilidad ambiental aplicad
'Foreign' books for English readers : published translations of navigation manuals and their audience in the English Renaissance, 1500-1640
No full textAlthough there has been an increasing interest in the study of Renaissance translations
and the early world of print, the history of navigation and exploration has not been the
subject of any such in-depth bibliographical research. This thesis identifies and
analyses a corpus of translated navigation manuals and related works that were printed
in England between 1500 and 1640.
The context is sketched by defining the different areas of maritime writing found in
Renaissance England. Although English contributions were particularly strong in such
topics as the mathematical side of navigation, the technical instruments and the debates
about magnetism and compass variation, publications of manuals and sailing directions
were scarce. This thesis reveals that such knowledge was imported from continental
Europe through translation. Forty-three translations out of seven different source
languages are discussed from a book-historical perspective to establish what their
source text was, how they came to England and who was responsible for translating
and publishing them.
Such information was obtained, in part, from a study of the paratexts, in particular the
translators’ and publishers’ dedications and addresses to the reader, which show the
reason and purpose of the translations, the methods employed and particular problems
encountered, as well certain linguistic and rhetorical characteristics. One work is
selected as a case-study for in-depth research, namely Martin Cortés’s Breue
compendio de la sphera y de la arte de nauegar (1551) and its translation by Richard
Eden, The Arte of Navigation (1561), which went through ten editions and became the
model for English navigation manuals.
Finally, by turning to the agents involved in the production and dissemination of these
translations, particularly the printers and booksellers, and establishing the connections
between them, this thesis reveals intricate social networks and sheds new light on
certain aspects of the fields of navigation, translation and print
Estudo comparativo de três projetos de restauração de áreas degradadas de manguezais da grande Florianópolis, SC
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-graduação em Engenharia Ambiental.Estudo comparativo de três projetos de recuperação em áreas de manguezais da Baia Norte, região da Grande Florianópolis, Santa Catarina, Brasil.O objetivo deste estudo foi comparar três projetos de restauração com plantio de mangues das três espécies típicas Avicennia schaueriana, Laguncularia racemosa e Rhizophora mangle, em áreas degradadas de manguezais na Baía Norte, região da Grande Florianópolis em Santa Catarina. Os plantios ocorreram durante o ano de 2000, em diferentes épocas e locais. As mudas utilizadas (plântulas) originaram-se do viveiro da Estação de Aqüicultura da UFSC e foram selecionadas dentre as com melhores condições de fitossanidade. Comparou-se dados sobre as áreas dos plantios, fatores ambientais, taxas de sobrevivência, altura das mudas, diâmetro da base e incremento anual desde a época do plantio 2000 até o final de 2003. As taxas de sobrevivência apresentaram valores que variaram de 90,51% no plantio no Saco Grande, no manguezal do Saco Grande; 67,55% no experimento do manguezal do Itacorubi, ambos em Florianópolis; e 23,3% no plantio na Praia da Bina, em Biguaçu. Em termos de desenvolvimento, a altura média foi de 1,58m e o incremento anual de 0,24 m/ano e o diâmetro da base variou de 3,93 cm e o incremento anual foi de 1,67 cm/ano. Estes índices mostram que, mesmo localizados no extremo sul de ocorrência de mangues, o plantio destas espécies é viável e permite-se dizer que as áreas foram restauradas com êxito. As condições ambientais distintas das três áreas influenciaram nos resultados obtidos e parece que a Lua influencia na época do plantio. Ressalta-se a necessidade das restaurações serem realizadas em época propícia, entre a primavera e o verão; o espaçamento deve ser no mínimo de 1,5 m - 2,0 m; o sombreamento da área deve ser levado em consideração, bem como, o monitoramento deve ser freqüente, quanto à limpeza dos terrenos, para que as mudas não sejam agredidas tanto por galhos caídos de árvores adultas como pelo lixo trazido pelas águas das marés e atacadas por herbívoros ou então pisoteadas
Consenso latinoamericano de hipertensión en pacientes con diabetes tipo 2 y síndrome metabólico
No full textThe present document has been prepared by a group of experts, members of cardiology, endocrinology, internal medicine, nephrology and diabetes societies of Latin American countries, to serve as a guide to physicians taking care of patients with diabetes, hypertension and comorbidities or complications of both conditions. Although the concept of metabolic syndrome is currently disputed, the higher prevalence in Latin America of that cluster of metabolic alterations has suggested that metabolic syndrome is a useful nosography entity in the context of Latin American medicine. Therefore, in the present document, particular attention is paid to this syndrome in order to alert physicians on a particular high-risk population, usually underestimated and undertreated. These recommendations result from presentations and debates by discussion panels during a 2-day conference held in Bucaramanga, in October 2012, and all the participants have approved the final conclusions. The authors acknowledge that the publication and diffusion of guidelines do not suffice to achieve the recommended changes in diagnostic or therapeutic strategies, and plan suitable interventions overcoming knowledge, attitude and behavioural barriers, preventing both physicians and patients from effectively adhering to guideline recommendations.O presente documento foi preparado por um grupo de especialistas, membros das Sociedades de Cardiologia, Endocrinologia, Medicina Interna, Nefrologia e Diabetes dos países da América Latina, para que sirva de diretriz para médicos que cuidam de pacientes com diabetes, hipertensão e fatores de risco concomitantes ou complicações de ambas as condições. Embora o conceito de síndrome metabólica seja atualmente muito discutido, a alta prevalência na América Latina do conjunto de alterações metabólicas que a compõem sugere que a síndrome metabólica é uma entidade nosográfica útil no contexto da medicina latino-americana. Devido a isso, no presente documento presta-se especial atenção a essa síndrome com a finalidade de alertar aos médicos sobre uma população particularmente de alto risco, que, por ser subestimada, não é tratada de forma adequada para os fatores de risco que constituem a síndrome metabólica. As recomendações deste documento são o resultado de apresentações e debates que ocorreram durante um encontro de dois dias em Bucaramanga (Colômbia), em outubro de 2012. Todos os participantes aprovaram as decisões finais. Os autores reconhecem que a publicação e difusão das diretrizes não serão suficientes para alcançar as mudanças recomendadas tanto em estratégias diagnósticas como terapêuticas, por isso programaram intervenções que permitirão identificar as barreiras do conhecimento, as atitudes e comportamento, o que permitirá tanto aos médicos como aos pacientes uma adequada adesão às recomendações sugeridas nestas diretrizes
José e 34 letras através do espelho /
No full textDissertação (Mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão.Esta dissertação apresenta resultados da leitura, indexação e análise de duas revistas cariocas: José - Literatura, Crítica & Arte (1976-78) e 34 Letras (1988-90). Na primeira revista, que teve dez números publicados sob a coordenação de Gastão de Holanda, percebe-se um projeto ainda atrelado à proposta e aos ícones modernistas (Drummond e Mário), enquanto a segunda, fruto do empenho de um grupo de estudantes da PUC-RJ, circula em sete números com um design gráfico bastante elaborado, abrigando em suas páginas várias tendências e linhagens. Os periódicos servem também para ler a crise e a emergência de dois perfis de intelectual: o legislador e o intérprete
Skyler and Bliss
No full textHong Kong remains the backdrop to the science fiction movies of my youth. The city reminds me of my former training in the financial sector. It is a city in which I could have succeeded in finance, but as far as art goes it is a young city, and I am a young artist. A frustration emerges; much like the mould, the artist also had to develop new skills by killing off his former desires and manipulating technology. My new series entitled HONG KONG surface project shows a new direction in my artistic research in which my technique becomes ever simpler, reducing the traces of pixelation until objects appear almost as they were found and photographed. Skyler and Bliss presents tectonic plates based on satellite images of the Arctic. Working in a hot and humid Hong Kong where mushrooms grow ferociously, a city artificially refrigerated by climate control, this series provides a conceptual image of a imaginary typographic map for survival.

Coleoptera of Brazil: what we knew then and what we know now. Insights from the Catálogo Taxonômico da Fauna do Brasil
No full textInternational audienceIn 2000, Cleide Costa published a paper presenting the state of knowledge of the Neotropical Coleopte ra, with a focus on the Brazilian fauna. Twenty-four years later, thanks to the development of the Coleoptera section of the Taxonomic Catalog of the Brazilian Fauna (CTFB - Catálogo Taxonômico da Fauna do Brasil) through the collaboration of 100 coleopterists from all over the globe, we can build on Costa's work and present an updated overview of the state of knowledge of the beetles from Brazil. There are currently 35,699 species in 4,958 genera and 116 families known to occur in the country, including representatives of all extant suborders and superfamilies. Our data show that the Brazilian beetle fauna is the richest on the planet, concentrating 9% of the world species diversity, with some estimates accounting to up to 15% of the global total. The most diverse family in numbers of genera is Cerambycidae (1,056 genera), while in number of species it is Chrysomelidae (6,079 species). Conotrachelus Dejean, 1835 (Curculionidae) is the most species-rich genus, with 570 species. The French entomologist Maurice Pic is the author who has contributed the most to the naming of species recorded from Brazil, with 1,794 valid names in 36 families, whereas the Brazilians Ubirajara R. Martins and Maria Helena M. Galileo are the only ones among the top-ten authors to have named species in the 21st century. Currently, approximately 144 new species of Brazilian beetles are described each year, and this average is projected to increase in the next decade to 180 species per year, or about one new Brazilian beetle every two days

30-day morbidity and mortality of sleeve gastrectomy, Roux-en-Y gastric bypass and one anastomosis gastric bypass: a propensity score-matched analysis of the GENEVA data
No full textBackground: There is a paucity of data comparing 30-day morbidity and mortality of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB). This study aimed to compare the 30-day safety of SG, RYGB, and OAGB in propensity score-matched cohorts. Materials and methods: This analysis utilised data collected from the GENEVA study which was a multicentre observational cohort study of bariatric and metabolic surgery (BMS) in 185 centres across 42 countries between 01/05/2022 and 31/10/2020 during the Coronavirus Disease-2019 (COVID-19) pandemic. 30-day complications were categorised according to the Clavien–Dindo classification. Patients receiving SG, RYGB, or OAGB were propensity-matched according to baseline characteristics and 30-day complications were compared between groups. Results: In total, 6770 patients (SG 3983; OAGB 702; RYGB 2085) were included in this analysis. Prior to matching, RYGB was associated with highest 30-day complication rate (SG 5.8%; OAGB 7.5%; RYGB 8.0% (p = 0.006)). On multivariate regression modelling, Insulin-dependent type 2 diabetes mellitus and hypercholesterolaemia were associated with increased 30-day complications. Being a non-smoker was associated with reduced complication rates. When compared to SG as a reference category, RYGB, but not OAGB, was associated with an increased rate of 30-day complications. A total of 702 pairs of SG and OAGB were propensity score-matched. The complication rate in the SG group was 7.3% (n = 51) as compared to 7.5% (n = 53) in the OAGB group (p = 0.68). Similarly, 2085 pairs of SG and RYGB were propensity score-matched. The complication rate in the SG group was 6.1% (n = 127) as compared to 7.9% (n = 166) in the RYGB group (p = 0.09). And, 702 pairs of OAGB and RYGB were matched. The complication rate in both groups was the same at 7.5 % (n = 53; p = 0.07). Conclusions: This global study found no significant difference in the 30-day morbidity and mortality of SG, RYGB, and OAGB in propensity score-matched cohorts. © 2021, The Author(s)
