Heart failure (HF) is a global pandemic affecting at least 26 million people worldwide and is increasing in prevalence. HF health expenditures are considerable and will increase dramatically with an ageing population. Despite the significant advances in therapies and prevention, mortality and morbidity are still high and quality of life poor. The prevalence, incidence, mortality and morbidity rates reported show geographic variations, depending on the different aetiologies and clinical characteristics observed among patients with HF. In this review we focus on the global epidemiology of HF, providing data about prevalence, incidence, mortality and morbidity worldwide.
Expert Comment: Is Medication Titration in Heart Failure too Complex?

Published: May 2017

Large-scale randomised controlled trials (RCTs) have demonstrated that angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and beta-blockers decrease mortality and hospitalisation in patients with heart failure (HF) associated with a reduced left ventricular ejection fraction. This has led to high prescription rates; however, these drugs are generally prescribed at much lower doses than the doses achieved in the RCTs. A number of strategies have been evaluated to improve medication titration in HF, including forced medication up-titration protocols, point-of-care decision support and extended scope of clinical practice for nurses and pharmacists. Most successful strategies have been multifaceted and have adapted existing multidisciplinary models of care. Furthermore, given the central role of general practitioners in long-term monitoring and care coordination in HF patients, these strategies should engage with primary care to facilitate the transition between the acute and primary healthcare sectors.

Published: May 2017

With the aim to study the inheritance of lethal gene ‘luteus-Pa’ in three derivated progenies from self and cross-fertilization of cacao (Theobroma cacao L) varieties, a study was carried out during January to September 2013. As genetic material C-25, S-5 y Pa-150 varieties were utilized and this one were self and cross pollinated and their progenies were divided in two replicates with 100 seeds each and sowed in plastic recipients containing a substrate 2:1(soil: sand). In order to contrast theobserved segregation with its expected homologous 3:1 (monogenic inheritance), the Chi-square (X2) test was utilized. The results shown that only one from self-fertilized progeny of C-25 variety exhibited the mendelian segregation 3:1 in both replicates, so that it lead to infer this one is carrier of lethal gene ‘luteus-Pa’ in heterozygote condition whereas that the progeny from Pa-150 x C-25 cross no found none lethal seedling and submitted to Chi-square (X2) test it could be to infer this one no segregate in the proportion 3:1 therefore, the Pa-150 variety is no carrier of this lethal gene. A better comprehension on photobiological origin, supported by molecular markers and the functional genomics of this mutant can help to identify and understand the factors involve in the photosynthetic mechanisms.

Characterization of soils cultivated with rubber in the Colombian Bajo Cauca Antioqueño region
Authors: Villa Cuastumal Martin Rodrigo , Martínez Bustamante Enrique Guillermo , Cartagena Valenzuela José Régulo , Rodríguez Rodríguez Orlando Antonio , Osorio Nelson Walter
Published: May 2017

From a socioeconomic and environmental standpoint, rubber cultivation is potentially important for Colombia, because it not only constitutes an alternative to the traditional mining, agricultural, and livestock activities, but also a beneficial option in the substitution of illegal crops. Thus, there is need to determine the factors restricting the productivity of the species, particularly soil-related aspects. In this context, the current research undertook the description and identification of soil physical and chemical properties in three rubber plantations located in a region known as Bajo Cauca Antioqueño, at the lower course of the Cauca river. The results indicate that these soils are classified as Ultisols, they are deep, with acid reaction and low levels of soil organic matter. Essential elements also exhibited low levels, except Cu. Fe and Al are also present in very high concentrations, while the cation exchange capacity is limited. These observations alert on the need for agronomic management techniques that allow the crop to express its full potential under conditions that are not very adequate for its growth and development.

Se determinó la bioconcentración del insecticida clorpirifos en plantas de pasto Cenchrus clandestinus cultivadas hidropónicamente, el pesticida fue aplicado en la solución de cultivo, se realizó el seguimiento de la concentración del pesticida en los tejidos del follaje y de la raíz, durante 72 h de exposición a la solución nutritiva con 96, 192 y 288 mg L-1 de clorpirifos. Los muestreos en tejidos se realizaron a las 4, 24, 48 y 72 h. Para la extracción del clorpirifos del follaje y raíz del pasto se empleó el método MI 48640 con una sensibilidad de 0,01 ppm y la cuantificación se realizó por cromatografía de gases. Durante el estudio se evidenció que el clorpirifos se transporta a través del sistema vascular de plantas de C. clandestinus en cultivo hidropónico, desde la raíz hasta el follaje. Además, se evidenció bioacumulación creciente en los tejidos de raíz y follaje. La bioacumulación del clorpirifos fue mayor en la raíz 39,4 µg g-1 que en el follaje 1,1 µg g-1. Por lo anterior, la utilización de este insecticida en los sistemas ganaderos de trópico alto representa un riesgo para los bovinos y para los demás integrantes de la cadena alimenticia láctea.

This essay presents the variety of vegetation which is utilized in traditional mining activities in the municipalities of Cértegui (Subdistricts of: Cértegui cabecera, La Toma y Recta Larga) and the Panamerican Union (Subdistricts of Animas, Agua Clara and Quiadó). The data is a product of an ethnographic investigation which selected 57 active traditional miners of the local population in the project’s area of influence to demonstrate a sample of the “Application of techniques and practices for cleaner production in gold and platinum mining in the department of Chocó”. These miners aided in recognizing, collecting, photographing, and identifying 78 species of vegetation used in activities associated with traditional mining such as: separation of metals (separating gold from jagua, settling the greasy gold and blackening the troughs), creating traditional tools (troughs, sifters, mining tools to store save and weigh gold) to work in different types of traditional mining (‘guaches’ or pits, mazamorreo or barequeo (gold-panning), hoyadero (underground mining), zambullidero (underwater mining), canalon (sluice box), agua corrida (streaming water), cuelgas (channels) and arrimadero), and confirming the affectivity by performing demonstrations of the separation of gold from jagua with mucilaginous strata of vegetation. Examples of this vegetation include: snakewood (Cecropia peltata), rhombus-leaved sida (Sida rhombifolia), Common Broom (Pavonia fruticosa), Shoeblackplant (Hibiscus rosa-sinensis), Balsa tree (Ochroma pyramidale) and Guácimo (Apeiba tibourbou).

The aim of this study is to investigate the relationship between nutritional status and the risk of falls in hospitalized elderly. This is a cross-sectional study with a sample of elderly (≥60 years), admitted to the geriatric inpatient unit of a teaching hospital, from May 2014 to September 2015. The variables were demographic data (gender and age), nutritional status the Mini Nutritional Assessment® and risk of fall through the Morse Fall Scale. There were 96 inpatients in this study, the average age was between 82.9±7.9 years (61 to 101 years), being 67.7% (65) from the female gender. According to the Mini Nutritional Assessment®, 53.2% (41) were malnourished, 35.1% (27) were at risk and 11.7% (9) were eutrophic. According to the Morse Fall Scale, 68.8% (66) of the patients had high risk of falling, 26% (25) had moderate risk and 5.2% (5) were at low risk. There was no association between the nutritionalstatus and the risk of fall, although it was observed that 59.6% of the malnourished elderly had high risk of falling and 47.6% at nutritional risk had also medium risk of falling. The elderly presented high risk of falls, besides high incidence of malnourishment. Despite that, there was no association betweennutritional status and risk of fall.

Objective: To observe the possible differences in the severity of the decline among elderly young and the oldest old.Methods: We identified all elderly young (60-79 years) and oldest old (80 or older) admitted to fall in 2010, in two Urgent Care Units and Emergency Hospital in Porto Alegre. Upon review of the service bulletins, data were extracted for the elderly, among them, the fall of the consequences, classified by the index proposed by Caberlon and Bos (2015). The mean decrease in severity were compared between the two age groups and tested by Student's t test. The relationship between gender, age and the degree of severity has been tested by chi-square. Results: Most attended were female (72%), among which 24% were long-lived. The percentage of long lifetime was significantly higher than the oldest (19%, p<0.001). The overall average severity score was 5.7. Oldest old showed an index of 6.5±5.45 while the elderly young had a lower rate of 5.5±6.39 (p<0.001). Women showed a higher frequency of severe gravity. Conclusion: We conclude that the oldest old have higher severity of falls. This conclusion also applies to the female sex, and fall more often have higher severity of falls mainly in the number of fractures in the evaluated age groups (young and the oldest old). Also completed is possible to use an assessment tool of decrease in quality that can be used in future research in order to contribute to the achievement of a surveillance more effective and resolute.

Introducción: La identificación de señales de alarma durante la Infección Respiratoria Aguda (IRA), es fundamental para disminuir el impacto de la enfermedad y la mortalidad asociada. El objetivo del estudio fue estimar la relación entre la edad y el nivel educativo al conocimiento sobre signos de alarma de IRA, en madres adolescentes. Materiales y Métodos: Estudio transversal, con una muestra aleatoria de 120 madres adolescentes adscritas a una fundación privada de la ciudad de Cartagena, a quienes se aplicó el cuestionario de Prácticas Claves sobre IRA propuesto por la Organización Panamericana de la Salud. Resultados: El promedio de edad de las participantes fue 17 ± 1.3 años. Se encontró que ser mayor de 17 años aumenta la probabilidad de reconocer por lo menos tres signos alarma [OR: 2.8 (IC 95%: 1.3 - 6.1)]. Asimismo, las adolescentes con un mayor nivel de escolaridad tienen más probabilidad de reconocer tres signos de alarma para la enfermedad [OR: 3.2 (IC 95%: 1.5 - 6.9)], que aquellas con menor nivel educativo. Discusión y Conclusiones: Determinantes personales como una mayor edad y escolaridad impactan de forma positiva en los conocimientos de las madres sobre los signos de alarma de IRA.

A simplified model of catenary action in reinforced concrete frames under axially restrained conditions
Authors: Pham Anh Tuan , Tan Kang Hai
Published: May 2017

From previous experimental studies on missing column scenarios, catenary action could provide beneficial effects on structures during load redistribution after a target column is suddenly removed under an alternative load path procedure to assess structural resistance to progressive collapse. However, full-scale structural tests are costly and time consuming. Equally, finite-element models require in-depth expertise and large computing resources. Practising engineers are not amenable to this approach for preliminary sizing of members or for a quick assessment of structural resilience. To address this need, this paper provides a simplified semi-analytical model for predicting structural response under a column loss scenario. The model is constructed based on finite-element simulations and is verified by test results. The simplified model idealises the structural response of reinforced concrete beam–column sub-assemblages under column loss scenarios as a piecewise multi-linear curve. It shows good agreement with published test results and validated finite-element simulations.
Internal Liquidity Management and Local Credit Provision
Authors: Coleman Nicholas , Correa Ricardo , Feler Leo , Goldrosen Jason
Published: May 2017

This paper studies the patterns of internal liquidity management and their effect on bank lending, using a novel branch-level dataset of Brazilian banks. Our results suggest that internal liquidity management increases during times of financial stress. Privately owned banks are most affected by a liquidity shock, and increase the level of internal funding to maintain their branch lending, while their government-owned competitors react strategically. Private and government banks increase the funding of branches in concentrated and riskier areas. This funding translates into more lending, as the sensitivity of lending to internal funding remains high after the liquidity shock. Altogether, this paper provides branch-level evidence of the way that banks ration internal liquidity, both in normal times and in times of stress, and the effect this has on bank lending.
Crimen corporativo y el discurso de la responsabilidad socioambiental: el bueno, el feo y el perfumado
Authors: De Souza Lionardo D. , Valadão Júnior Valdir M. , De O. Medeiros Cintia R. , Gallego Esther S.
Published: May 2017

Las críticas a la noción de responsabilidad social corporativa establecen que se trata de un movimiento ideológico usado para legitimar el poder de las grandes corporaciones. En esta investigación, se analizan los discursos de responsabilidad social de una corporación que ha sido protagonista de un crimen ambiental, con el objetivo de identificar la relación entre lo que se declara o pregona y lo que se practica. Al ser una investigación documental, metodológicamente se estudian archivos de la compañía y de la Alcaldía del municipio donde ocurrió el crimen. Se encontró como resultado que la mencionada empresa utiliza el discurso de la responsabilidad socioambiental para ocultar prácticas indebidas que perjudican al medio ambiente y la comunidad; es decir que para no ser considerada una corporación mala o fea, perfuma sus prácticas con discursos de protección al entorno natural.

RESUMENTradicionalmente, la transcripción de entrevistas, ya sea individuales o grupales, constituye, con frecuencia, el material empírico básico para llevar a cabo estudios cualitativos en ciencias sociales y de la educación. Sin embargo, la utilización de estrategias visuales (dibujos, fotografías, videos) se ha convertido en las últimas décadas en un recurso metodológico especialmente sensible y adecuado para aquellas personas que, por distintas razones, no tienen un nivel lingüístico o comunicativo desarrollado. Este es el caso, por ejemplo, de niños y niñas, personas de origen extranjero con poca competencia en la lengua de la sociedad de destino o de algunas personas con discapacidad intelectual. El objetivo de este artículo es describir e ilustrar la utilización metodológica de recursos visuales, así como discutir sus posibilidades, a partir de ejemplos de su uso desarrollados en tres investigaciones socioeducativas.  ABSTRACTTraditionally, the transcription of interviews, either individual or group, has become the basic empirical material to conduct qualitative studies in social sciences and education. However, in the last few decades, the use of visual strategies (drawings, photographs, videos) has become a methodological resource, particularly sensitive and suitable for those people who do not have a level or communicative language developed for whatever reason. This is the case of children, people of foreign origin with less competence with the language of the society of destination or people with intellectual disabilities, for example. The objective of this article is to describe and illustrate the use of methodological visual resources within the framework of three research projects. We discuss the advantages and disadvantages of the use of these strategies through experience with the projects that are described and illustrated in this article.

La lettre d’Osmundus, évêque d’Astorga, à la comtesse Ide de Boulogne (avant 1096). The epistle from Osmundus, bishop of Astorga, to the countess Ida of Boulogne (before 1096)
Authors: Henriet Patrick
Published: May 2017

Resumen: La carta de Osmundo de Astorga a la condesa Ide de Boulognese puede fecharse de los años 1082-1096, y quizas mas precisamente de los años 1087-1096. Propone une versión precoz y muy particular de la historia de la venida de reliquias muy prestigiosas desde Jerusalén hasta España, une historia que conoció un desarollo mucho mas amplio en Oviedo, alrededor del arca sancta. Osmundo era probablemente originario del norte de los Pirineos. Planteamos aqui la posibilidad de un origen en el norte de Francia y de posibles contactos con la condesa de Boulogne antes de su llegada en la península. Su carta revela por otra parte el conocimiento de la leyenda de los siete varones apostólicos, quizas a través de la Epistola Leonis. Proponemos también una nueva edición de la carta.Abstract: The letter of Osmundus of Astorga to the countess of Boulogne can be dated from the years 1082-106, maybe 1087-1096. It gives us an early and very special version of the translation of a group of prestigious relics from Jerusalem to Spain. This same story was developed with important differences in Oviedo, with the legend of the arca sancta. Osmundus came probably from an area located at the north of the Pyrenees. We suggest that he could have live in Northern France and that he had contacts with the countess before coming to Spain. This letter shows otherwise the knowledge of the « siete varones apostólicos’s » legend, possibly through the Episola Leonis. Finally we give a new edition of this letter.
El Sudario de Oviedo: historia antigua y moderna. The Shroud of Oviedo: ancient and modern history
Authors: Nicolotti Andrea
Published: May 2017

Resumen: En la Edad Media, había una gran variedad de sudarios venerados en distintas zonas del mundo cristiano. El sudario de Oviedo, tejido en torno al siglo VIII d.C, aparece registrado en las fuentes a partir del último cuarto del siglo XI y forma parte de las reliquias conservadas en la catedral de la ciudad. Su existencia puede considerarse uno de los efectos de los esfuerzos conjuntos que el clero y la política realizaron para proveer una legitimación histórica y propagandística a la supremacía de la sede de Oviedo. En los últimos cincuenta años, como consecuencia de la poderosa propaganda efectuada por algunos exponentes de una pseudo-ciencia conocida como “sindonología”, el Sudario de Oviedo goza de creciente fama, sobre todo mediática, y es presentado como si fuera una reliquia auténtica, es decir, como el verdadero sudario que envolvió la cabeza de Jesús de Nazaret.Abstract: In the Middle Ages, there was a great variety of shrouds venerated in different parts of the Christian world. The Sudarium of Oviedo, woven around the eighth century AD, is recorded in the sources as from the last quarter of the eleventh century and is one of the relics preserved in the cathedral of the city. Its existence can be considered one of the effects of the joint efforts that the clergy and the political power made to provide a historical and propagandistic legitimation to the supremacy of Oviedo’s bishopric. In the last fifty years, as a result of the powerful propaganda carried out by some exponents of a pseudo-science known as “syndonology”, the Sudarium of Oviedo enjoys a growing fame, especially in the media, and it is presented as if it were an authentic relic, that is, as the true shroud that wrapped the head of Jesus of Nazareth.
The last deglaciation of Alaska
Authors: Briner J.P. , Tulenko J.P. , Kaufman D.S. , Young N.E. , Baichtal J.F. , Lesnek A.
Published: May 2017

We review available chronologies that constrain the timing of glacier fluctuations during the last deglaciation in Alaska. We address three questions relating to the last glacial termination: (i) How did the timing of glacier recession relate to buildup of global CO2, such as during the onset of CO2 rise at ~18 ka? (ii) Did glaciers fluctuate in synchrony with Heinrich Stadial 1 (18-14.6 ka)? And, (iii) what is the spatio-temporal pattern of glacier change during the climatically turbulent late glacial interval (14.6-11.7 ka)? The existing record is incomplete, yet reveals that most Alaskan glaciers experienced significant retreat (~40% of their Last Glacial Maximum lengths) prior to the onset of CO2 rise ~18 ka. This points to stronger insolation forcing of Alaskan glaciers compared to mid-latitude glaciers. Despite some glacier re-advances and standstills during Heinrich Stadial 1, most glaciers continued to recede. This suggests that glaciers in Alaska were relatively immune to the far-field effects of Atlantic meridional overturning circulation. Finally, the majority of glaciers (9 out of 14 available records) were up-valley of their late Holocene glacier extents during the Younger Dryas. Most of the sites with evidence for relatively extensive glaciers during the Younger Dryas are in southern Alaska, which may relate to moisture changes associated with the flooding of Bering Strait as much as it does to changes in North Atlantic Ocean circulation.
Deglaciation of the Colorado Rocky Mountains following the Last Glacial Maximum

Published: May 2017

The availability of almost 180 cosmogenic-radionuclide (CRN) surface-exposure ages from moraine boulders and glacially polished bedrock surfaces makes possible an assessment of the timing and character of the local Last Glacial Maximum (LLGM) and subsequent deglaciation in the Colorado Rocky Mountains. A review of glacial chronologies and numerical modeling results indicates that although glaciers across Colorado responded broadly synchronously, apparent differences in the timing and magnitude of glacier retreat following the LLGM suggest that spatially variable regional forcing, possibly precipitation related, played a role in glacier behavior along with more spatially uniform hemispheric or global forcing. Glaciers in the five ranges examined reached their greatest LLGM extents before ~19.5 ka and abandoned their outermost LLGM moraines between ~23.5 and 19.5 ka. Detailed deglaciation chronologies are available for glaciers in four of the ranges. In the Sawatch Range and Sangre de Cristo Mountains, glaciers were near their LLGM extents at 17-16 ka, before retreating rapidly. In the San Juan Mountains and the Front Range, glaciers may have begun their post-LLGM recession earlier, although early deglaciation is indicated by only a few ages on polished bedrock that potentially contains pre-LLGM CRN inheritance, and thus may be too old. Regardless of the timing of the onset of deglaciation, the equilibrium-line rise associated with deglaciation was earlier and significantly larger in the San Juan Mountains than elsewhere in Colorado. This suggests that the San Juan Mountains, located well to the southwest of the other ranges, may have experienced enhanced precipitation during the LLGM, as did areas farther to the south and west, while LLGM conditions may have been drier in the northern and eastern Colorado ranges. A breakdown in this pattern after the LLGM, with precipitation decreasing in the south and west and increasing in the north and east, may have led to the range-to-range differences evident across Colorado. Deglaciation was nearly complete in all four ranges by 15-13 ka. While some proxy records indicate a later Younger Dryas-age cooling in the Colorado mountains, there is not clear moraine evidence of glacier readvance at that time.
Effects of capnoperitoneum for laparoscopy on liver, renal and pulmonary functions: a prospective observational study
Authors: G. Gautham , Anand Chetan , S. Manoj Karthik , R. Pajanivel
Published: May 2017

Background: Laparoscopy is the mainstay of surgical intervention in today’s era. Carbondioxide is an ideal insufflation gas, for creating pneumoperitoneum for laparoscopic surgeries. Although capnoperitoneum has been established as safe gas, our study was carried out to assess any clinical or subclinical changes produced by capnoperitoneum in a semiurban setting thereby creating awareness among our suburban population and also to add to the existing research data.Methods: We studied 60 patients who underwent laparoscopic surgeries in various surgical disciplines at our institution between October 2014 and August 2016 and fulfilling the inclusion criteria. The pre-operative and post-operative values of liver, renal and pulmonary functions were collected. These parameters were assessed using paired t test. Patient’s with preexisting diseases of these systems were excluded from the study.Results: Of the 60 patients assessed, there was a change in the values of the pre and postoperative values of the liver, renal and the pulmonary function tests, but these changes were insignificant as assessed by the paired t test. The demographic data was representation of the population who took part in the study.Conclusions: Laparoscopic surgeries using capnoperitoneum produce a transient change in the parameters of the liver, renal and pulmonary functions. However, these insignificant changes also were evidenced to fall back to normal range within short interval of time. Thus, it can be concluded that capnoperitoneum does not produce any clinical or sub-clinical changes, and is considered safe, in patients with normal organ functions.

Estimular o desenvolvimento dos territórios rurais implica em orientar políticas públicas segundo as demandas expressadas pelas comunidades e organizações da sociedade, reconhecendo as especificidades de cada território e ofertando instrumentos de desenvolvimento que atendam inclusive o agricultor familiar. Nesse sentido, este artigo tem por objetivo analisar os efeitos do Programa Nacional de Aquisição de Alimentos – PAA no cenário da agricultura familiar, a partir de um estudo em Rio Branco do Sul e Itaperuçu, municípios paranaenses do Vale do Ribeira. Como resultados constatou-se que o Programa tem um papel estratégico para potencializar a produção de alimentos da agricultura familiar nos municípios analisados, assegurando preço justo, valorizando a agrobiodiversidade e a cultura alimentar, gerando renda e incluindo os agricultores em processos de comercialização local, apesar das mudanças pontuais que devem ser realizadas. Conclui-se que a situação da atividade foi otimizada se realizado um comparativo desde década de 1970. Apesar de uma forte dependência dos beneficiários em relação ao Programa, é evidente a importância e a melhoria nas políticas públicas de financiamento e apoio à agricultura familiar.

A Estação Ecológica do Taim é uma Unidade de Conservação (UC), localizada na porção Sul da PlanícieCosteira do estado do Rio Grande do Sul, Brasil. Abrange parte dos municípios do Rio Grande e de SantaVitória do Palmar, entre a Lagoa Mirim e o Oceano Atlântico. Embora tenha sido estabelecida há trintaanos e seja internacionalmente reconhecida como importante área úmida e de proteção de espéciesameaçadas, essa UC ainda carece de plano de manejo e de ordenamento territorial. Imersa em umamatriz cultural e de atividades produtivas conflitantes com os interesses de conservação, a participaçãoda sociedade na elaboração do plano de gestão é um aspecto fundamental. Desta forma, foi aplicadoum diagnóstico participativo como mecanismo para apreender os modos de relacionamento dapopulação local e seus conhecimentos sobre o meio ambiente onde está inserida a UC, bem como paraidentificar a percepção da comunidade científica envolvida com pesquisas naregião. As informaçõesobtidas por meio do diagnóstico participativo, espacializadas em um Sistema de Informação Geográficae interpretadas juntamente com dados físicos, biológicos e antrópicos, permitiram caracterizar noterritório ameaças e oportunidades à conservação na área da Unidade. Tal investigação tornou possívelpropor um esquema de zoneamento de usos, e a identificação de ações de manejo de forma a subsidiaro planejamento e o ordenamento territorial para essa UC.

O turismo de observação de cetáceos (TOC) pode contribuir para a conservação de cetáceos e desenvolvimento econômico local. Este estudo teve como objetivo caracterizar o turismo de observação de botos-cinza, de forma a subsidiar o plano de manejo da Reserva Faunística Costeira de Tibau do Sul (REFAUTS). Durante quatro expedições à área de estudo, foram realizadas entrevistas com mestres de embarcação, censos e vistorias nas embarcações licenciadas e registro do fluxo do TOC. Nós registramos 11 embarcações licenciadas operando na REFAUTS, 368 passeios durante 16 dias de amostragem e um total de 4.717 turistas. Na REFAUTS, os mestres de embarcação não cumpriram a determinação prevista em lei quanto a limitação do número de barcos nas enseadas em 30% dos registros. O TOC na REFAUTS vem desempenhando um papel importante na economia local, contudo é preciso que um plano de ação seja implantado, para assegurar a conservação do boto-cinza na REFAUTS.

Published: May 2017

A disposição final adequada dos resíduos sólidos urbanos (RSU) tem se constituído em um dos graves problemas ambientais da atualidade. Entre as formas de disposição dos resíduos, o aterro sanitário é considerado a mais adequada. Nessa perspectiva, o presente artigo objetiva analisar a sustentabilidade do aterro sanitário situado na zona rural do município de Puxinanã/PB. Para tanto, fez-se uso do Índice de Qualidade de Aterros de Resíduos Sólidos Urbanos (IQA), tendo sido este instrumento adaptado de modo a atender à realidade encontrada. Observou-se, com base nos dados coletados, que o aterro em foco não atende às normas existentes (NBR 8419/1992; 13.896/1997), possuindo condições inadequadas de funcionamento em virtude, entre outros motivos, da ausência de cobertura diária dos resíduos ali depositados; inexistência de separação e triagem dos resíduos recicláveis e compostáveis; acúmulo do lixiviado, gerando problemas ambientais e para a população, bem como contribuindo para a insustentabilidade da gestão dos RSU.

Authors: Clark Jordan , Tromovich Pavel
Published: May 2017

This action research project explored the use of gestures for teaching and learning French vocabulary in an upper-beginner adult classroom with 21 students from various language backgrounds. Over the course of 4 weeks, the teacher developed and used 4 sets of themed activities using both teacher- and student-generated gestures to introduce new vocabulary to the students, encouraging students to take an active role with respect to creating gestures. Detailed classroom observations and the teacher’s field notes showed that students became comfortable using gestures after the first class and that the gesture activities had positive effects on student participation and the classroom interaction. Weekly quizzes and a final vocabulary test revealed bene ts of gesture-based activities for word learning. Students’ comments suggested that they enjoyed the gesture activities and that the gestures helped them remember words be er, particularly when the word naturally evoked a gesture or when the gesture contained clues to word length or pronunciation. Several pedagogical considerations guiding the design and implementation of gesture-based vocabulary activities in a second language classroom are discussed.----Cette recherche-action action a exploré l’utilisation de gestes pour l’enseignement et l’apprentissage du vocabulaire en français dans un cours pour adultes débutants-intermédiaires.

Depuis plus de deux décennies, les mesures de lutte antivectorielle contre la trypanosomose sont menées dans la zone des savanes du Cameroun. Afin d’évaluer l’impact de ces mesures sur la prévalence de la maladie, trois zones (zone assainie, zone de front et zone non assainie) ont été localisées sur le plateau de l’Adamaoua. Des échantillons sanguins prélevés sur 349 animaux vivant dans ces zones ont été utilisés pour mesurer l’hématocrite. En outre, à partir des couches leucocytaires obtenues de ces échantillons, des observations microscopiques ont permis la détermination des taux d’infection trypanosomienne et les niveaux de parasitémie de ces animaux. Des infections trypanosomiennes mixtes ou simples ont été détectées chez 40,7 p. 100 des animaux. Trypanosoma congolense a été l’agent étiologique identifié prédominant et 9,2 p. 100 des animaux infectés étaient porteurs au moins de deux espèces parasitaires, avec une prédominance de l’association T. congolense et T. vivax. La prévalence de la trypanosomose a été de 61,1, 21,4 et 24,7 p. 100, respectivement dans les zones non assainie, de front et assainie. Des taux d’hématocrite inférieurs ou égaux à 25 p. 100 (révélateurs d’une infection) ont été enregistrés chez 12,6 p. 100 des 349 animaux examinés et 75 p. 100 de ces animaux étaient porteurs de trypanosomes. Une corrélation négative entre la parasitémie et l’hématocrite (r = -0,19 ; p < 0,001) a été observée. Il n’y a pas eu de différence significative (p > 0,05) entre la prévalence de l’infection dans les différents groupes d’âge des animaux. Les taux d’infection trypanosomienne ont été significativement plus élevés (χ2 = 6,00 ; p < 0,05) chez les mâles (46,1 p. 100) que chez les femelles (35,6 p. 100). Ces résultats ont montré que la trypanosomose était endémique dans cette région et qu’il y avait eu une réinfestation des zones anciennement assainies. Des stratégies de gestion participative et de maintenance durable de ces pâturages doivent être recherchées.

L’effet d’un aliment concentré et de l’aliment traditionnel sur les performances pondérales du porc local du Nord Cameroun, et leur impact sur les revenus des éleveurs ont été comparés en milieu paysan pendant 75 jours. Au terme de l’essai, les porcelets alimentés avec le concentré ont présenté un poids de près de 60 p. 100 supérieur à celui des porcelets alimentés traditionnellement, soit un poids final respectivement de 26 et 16,1 kg. De même, les gains moyens quotidiens ont été de 206 et 74 g pour les porcelets soumis respectivement à l’aliment concentré et à l’aliment traditionnel. Sur le plan économique, la marge brute obtenue avec le concentré a été de 2 837,14 contre 950 francs CFA en moyenne avec les rations traditionnelles. Cette étude a montré qu’il serait possible d’améliorer la productivité des porcs de race locale du Nord Cameroun et ainsi le revenu des éleveurs en améliorant l’alimentation des animaux.
