El Agave tequilana Weber es una opción para la producción de bioetanol combustible. La cosecha manual del agave representa el 75 % de los costos de producción del cultivo, lo que ocasiona un mayor costo de producción del bioetanol que para otros cultivos. En este trabajo se presenta una propuesta de cosechadora-desmenuzadora de agave, para lo cual se consideran: propuestas existentes, la metodología de cosecha actual, máquinas agrícolas con mecanismos de interés y los requerimientos de la materia prima para producir bioetanol. La cosechadora propuesta considera el desmenuzado de hojas y piña en campo, retomando ideas de mecanismos empleados en molinos de piña de agave y desmenuzadoras agrícolas. La cosecha mecanizada de agave para producción de bioetanol presenta viabilidad técnica que requerirá una investigación para diseñar el mecanismo desmenuzador, su disposición geométrica y dimensiones, así como la potencia requerida en el desmenuzado, con el fin de dimensionar distintos elementos de la cosechadora.

Authors: Castañeda Miranda Alejandro , González Parada Adrián , Guzmán Cabrera Rafael , Ibarra Manzano Oscar G.
Published: October 2019

Recientemente, el aprovechamiento de la energía solar en el deshidratado de productos agrícolas se ha vuelto cada día más común debido a los altos rendimientos en los productos post-cosecha. La inversión en tecnologías propias para contribuir con los productores del sector agroalimentario es un factor importante para el desarrollo de las cadenas produc­tivas de nuestro país. En este trabajo se presenta el desarrollo de un horno solar para el secado de plantas y vegetales utilizando control difuso. Este es un sistema térmicamente controlado que permite disminuir el tiempo de secado de varios días a unas horas. Se reali­zaron pruebas de secado usando flor de jamaica, en las cuales se pudo disminuir el tiempo de secado de cuatro días a aproximadamente 5 h. Se presentan tanto la parte de diseño conceptual, como resultados experimentales del mismo. Los resultados obtenidos permiten ver la viabilidad del diseño propuesto.

Authors: Sánchez-Márquez J. A. , Fuentes-Ramírez R. , Galindo-Esquivel I. R. , Martínez-Hernández A. L. , Velasco-Santos C.
Published: October 2019

La oxidación de los nanotubos de carbono, ha generado gran interés porque además de eliminar impurezas, aumenta el grado de dispersión de los agregados y logra nuevas in­teracciones entre los materiales. En este trabajo, nanotubos de carbono (NTC) fueron tra­tados con diferentes métodos de oxidación para conocer la modificación superficial que cada tratamiento efectúa en la estructura del material. Los métodos contrastados fueron el tratamiento químico tradicional (mediante ácidos fuertes) y el tratamiento asistido por microondas. Los resultados mostraron que ambos tratamientos disminuyen el área super­ficial (NTC tradicional < NTC microondas < NTC sin tratamiento). Utilizando microondas, se redujo el tiempo de oxidación, se obtuvo una mayor concentración de grupos funcionales carboxílicos y se disminuyó el daño en la estructura con lo que se obtienen nanotubos oxi­dados con mejores características estructurales.

Es común la obtención de muestras de suelos agrícolas mediante el equipo Uhland. El ín­dice crítico de compactación del suelo se establece con la prueba Proctor. El objetivo fue la comparación física del muestreador Uhland, con caída libre y forzada del martillo, con el aparato Proctor para valorar la alteración mecánica de la muestra. Se utilizaron los Proctor estándar y modificado, el Uhland a caída libre y forzada del martillo, un diseño estadístico completamente aleatorizado con diez repeticiones y cuatro tratamientos, Análisis de Va­rianza, Mínima Diferencia Significativa y regresión polinómica. Se concluyó que el Uhland produjo resultados similares al Proctor. La energía penetrante del Uhland resultó superior a la compactante del Proctor. La humedad del suelo influyó sobre la densidad aparente seca. La relación de solidez y la porosidad aerífera identificaron mejor el proceso.
La comensalidad identitaria un reto para las políticas públicas de salud. El caso del mulli al asado de boda en la Gran Chichimeca
Authors: Romero Ugalde Maricruz
Published: October 2019

La Gran Chichimeca se concibe como una zona de intercambio cultural constante entre grupos sedentarios y nómadas que se ubica de San Juan del Río al suroeste de Estados Unidos. En el presente trabajo se muestran relaciones entre algunas poblaciones de los actuales estados de Querétaro a Zacatecas a partir de las comidas empleadas en los rituales conmemorativos del ciclo vital y festivo para demostrar cómo a través de los alimentos y sus formas de preparación es posible dar cuenta de los intercambios culturales en la zona, ubicando las transformacio­nes y continuidades que promueven factores identitarios a partir de la comensalidad ritual. Algunas de las preguntas que guían la exposición son: ¿Es posible identificar continuidades en el uso del maíz y el chile? ¿Cómo se modifica la incorporación del guajolote al cerdo? ¿Por qué hay platillos cuya denominación hace explícita la referencia a lo indio? ¿Cómo se rela­ciona la comensalidad con políticas internacionales como el derecho a la alimentación o el reconocimiento de ciertas cocinas como patrimonio cultural de la humanidad?

Amplitude variation in fractional multiple-interference on N-beams
Authors: Alvarado Méndez E. , Trejo Durán M. , Estudillo Ayala J. M. , Rojas Laguna R.
Published: October 2019

Multiple periodic patterns by light interference are a complicated problem from an experimen­tal point of view. We report a theoretical model of the incidence of N beams of light at one point in space. Two components of the electric field are projected: azimuthal (angle formed with the projection of the vector in space on the x-y plane) and zenithal (angle of the incident vector with the z-axis). As a result, azimuthal intensity and zenithal intensity are found. The case of fractional amplitude or fractional number of beams is analyzed. When the phase is modified, the process allows us to visualize the change of geometry. Quasi-lineal patterns to maximum and minimum concentric circles are observed. Some applications of these patterns can be found in sensors and engraving in some lithography processes.

The Influence of Curing Time on Restrained Shrinkage Cracking of Concrete with Shrinkage Reducing Admixture
Authors: Bagheri Alireza , Jamali Armin , Pourmir Mina , Zanganeh Hamed
Published: October 2019

The positive effect of increased duration of curing in enhancing strength and durability of concrete is well established. However, there have been reports suggesting that longer curing times can result in increased drying shrinkage and can affect restrained shrinkage cracking. Although shrinkage reducing admixtures (SRAs) were introduced to the concrete industry about 25 years ago, the effect of curing time on their restrained shrinkage performance has not been previously investigated. In this study, the effects of three curing times of 1, 3, and 7 days on drying shrinkage performance of the control mix (mix without SRA) and the mix containing SRA were investigated. The results indicate that the restrained shrinkage cracking potential of the control mix increased with increased duration of curing. However, for the mix containing SRA, an opposite effect was observed and longer curing reduced both the free drying shrinkage and potential for restrained shrinkage cracking. The results also indicate that by increasing the curing time, the crack width for the control mix increased, whereas there was no significant effect on the crack width of the mix containing SRA.

Published: October 2019

Low-density polyethylene (LDPE) is extensively used as packaging material, and as

such has a short service life, but long environmental persistence. The alternative to reducing the impact of LDPE as packaging material on the environment is to blend it with carbohydrate-based polymers, like starch. Therefore, the focus of this investigation was to prepare bio-based blends of LDPE and thermoplastic starch (TPS) containing different amounts of TPS using a Brabender kneading chamber. Due to incompatibility of LDPE/ TPS blends, a styrene–ethylene/butylene–styrene block copolymer, grafted with maleic anhydride (SEBS-g-MA) containing 2 mol % anhydride groups, was added as a compatibilizer. The effect of the biodegradable, hydrophilic TPS, its content, and the incorporation of the compatibilizer on the properties of LDPE/TPS blends were analysed. The characterization was performed by means of thermogravimetric analysis (TG), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and water absorption (WA). Based on the results of the morphological structure, a good dispersion of the TPS phase in LDPE matrix was obtained with the incorporation of compatibilizer, which resulted in better thermal and barrier properties of these materials.

Las decisiones públicas y las estrategias de desarrollo ante la incidencia de los organismos internacionales en el escenario de crisis de Estado en México
Authors: Enríquez Pérez Isaac
Published: October 2019

Las decisiones públicas y la intervención estatal en la dialéctica desarrollo/subdesarrollo, en buena medida, se definen y transforman a la luz de la gravitación que ejercen los organismos internacionales y los espacios globales para la toma de decisiones; especialmente a partir del despliegue de su poder epistémico/cognitivo que articula comunidades epistémicas trans-territoriales a las cuales se incorporan activamente ministerios estratégicos y funcionarios especializados de las élites políticas nacionales.
La inserción de naciones subdesarrolladas como México no siempre es ventajosa, sino que se recrudece con la generalizada crisis de Estado y la pérdida de control respecto a las fuerzas, factores y poderes fácticos que condicionan la toma de decisiones. Se trata de reconocer que, entre las escalas nacionales donde se fraguan las decisiones públicas de las estrategias de desarrollo y el plano de los organismos internacionales, subyace una relación orgánica signada por un condicionamiento recíproco y un consentimiento orientado a crear un discurso hegemónico, así como cursos de acción respecto al tratamiento de los problemas públicos y sus posibles soluciones. Enfatizar en el sentido y las facetas de esta relación estrecha es relevante porque contribuye a identificar las fuentes de las decisiones públicas. Para ello, se aprovechará el trabajo empírico realizado en otras investigaciones (principalmente el análisis de documentos estratégicos de algunos organismos internacionales) en aras de brindar contenido a conceptos que permitan comprenden la acción social de estas organizaciones.

Authors: Ghorbanpour Manoochehr , Seyfrabie Mohammad Ali , Yousefi Babak
Published: October 2019

Objective. Patients undergoing Soave surgery for Hirschsprung's disease are at risk for some complications. The aim of this study was to investigate such short-term and long-term complications and evaluate the outcome of the operation in these patients.

Methods. A case series study was carried out during the last 12 years, during 2007 to 2018 in Besat hospital of Hamadan. Data collection conducted using a checklist includes questions about demographic information, clinical features, and short-term and long-term complications, and consequences of post-operative surgery. The findings of the study were analyzed using SPSS software version 20 and appropriate statistical tests. P-value less than 0.05 was considered statistically significant.

Results. A total of 55 children underwent Soave surgery during the last 12 years in Besat Hospital Hamadan, Iran. The mean age of the patients was 38±10 days during surgery, of which 56.4% were female. The mean hospital stay was 7.3 days. Also, the mean weight of children at birth was 2970±447 gr. Most of the patients were born as NVD (52.7%) and term (74.5%). The most common comorbidity was congenital heart disease. The most common short-term complication was intestinal obstruction in 14 patients (25.5%) and the most frequent long-term complication was intestinal obstruction and constipation (27.3% each cases). The mortality rate of patients in this study was 14.5% in total.

Conclusions. One stage surgical procedure in Hirschsprung's disease is a safe and effective method, but care should be taken in choosing patients and patients should be monitored for possible complications, so that they can be considered and implemented for proper treatment.
Cardiovascular magnetic resonance: contribution to the exploration of cardiomyopathies
Authors: Schiau Călin , Schiau Șerban , Dudea Sorin M. , Manole Simona
Published: October 2019

Introduction. Magnetic resonance imaging is a non-invasive and non-irradiating imaging method, complementary to cardiac ultrasound in the assessment of cardiovascular disease and implicitly of cardiomyopathies. Although it is not a first intention imaging method, it is superior in the assessment of cardiac volumes, left ventricular ejection fraction, in the analysis of cardiac wall dyskinesia and myocardial tissue characteristics with and without using a contrast agent. The purpose of this paper is to review the current knowledge regarding cardiovascular magnetic resonance imaging (CMR) and its applications in cardiomyopathy analysis.

 

Methods. In order to create this review, relevant articles were searched and analyzed by using MeSH terms such as: "cardiac magnetic resonance imaging", "cardiomyopathy", "myocardial fibrosis". Three main international databases PubMed, Web of Science and Medscape were searched. We carried out a narrative review focused on the current indications of cardiovascular magnetic resonance imaging in cardiomyopathies, both common and raret, of ischemic and nonischemic types.

 

Results. Cardiac magnetic resonance imaging has a very important role in the diagnosis, assessment and prognosis of common cardiomyopathies (the dilated, hypertrophic and inflammatory types) or other more rare ones such as (amyloidosis, arrhythmogenic right ventricular, non-compaction or Takotsubo cardiomyopathy), as it represents the gold standard for evaluating the ejection fraction, ventricular volumes and mass. CMR techniques, such as late gadolinium enhancement, T1 and T2 mapping have proven their usefulness, helping differentiate between ischemic (subendocardial enhancement) and nonischemic cardiomyopathy (varied pattern) or also establish the etiology. Another important feature of this imaging technique is that it can establish the myocardial viability, thus the chance of contractile recovery after revascularization. This feature is based on the transmural extent of LGE, left ventricle wall thickness and the assessment of the contractile reserve after administration of low dose dobutamine.

Conclusions. Cardiovascular magnetic resonance imaging is an indispensable tool, with proven efficiency, capable of providing the differential diagnosis between ischemic and nonischemic cardiomyopathy or establishing the etiology in the nonischemic type. In addition, these findings have a prognostic value, they may guide the patient management plan and, if necessary, can evaluate treatment response. Therefore, this technique should be part of any routine investigation of various cardiomyopathies.

Distribution of migratory fish in the stream (depth, velocity, body size, predators)
Authors: Chemagin A. A.
Published: October 2019

In order to supplement the available information for the eco-hydraulic approach to designing fish passages, taking into account the taxonomic, dimensional structure, as well as taking into account the presence of predatory fish in the stream, the distribution of migratory fish of the boreal plain faunistic complex (Russian Federation) was studied. Three depth-velocity sections from the shore to the midstream were investigated: 5 m and 27.8 cm/s, 8 m and 44.4 cm/s, 11 m and 55.6 cm/s. Analysis of the migration distribution of fish showed that in the direction from the shore to the midstream, the proportion of representatives of Cyprinidae decreases from 41.8–24.3% and that of Percidae decreases from 25.0–18.4%. For individuals of two groups: the Acipenseridae and Lotidae, Coregonidae and Esocidae, patterns of distribution in the structure of migratory fish are opposite – their share increases with increasing speed and depth characteristics: 23.0–40.2% and 10.2–17.1%, respectively. An assessment of the dimensional structure revealed a feature of increase in the size range of fish from the shore to the midstream: the dominance of small individuals (<10 cm) in the shore area is replaced by the dominance of large fish (> 30 cm) in the area of higher speeds and depths. A significant difference in the distribution for all studied taxonomic fish groups between the shore and the midstream was shown. Thus, it has been established that for Cyprinidae during the migration period, the choice shifts in favour of minimizing energy costs, and the choice to avoid the risk of predation from individuals of the groups: Coregonidae and Esocidae, and also Percidae, shifts in favour of the former. The distribution of perch is influenced by the reduction of energy costs and the simultaneous avoidance of predation and cannibalism. For the fish group Acipenseridae and Lotidae, their predominance in the deeper area is due to their less developed visual orientation mechanism in the stream because they are bottom-living fish species.
The non-native woody species of the flora of Ukraine: Introduction, naturalization and invasion
Authors: Burda R. I. , Koniakin S. N.
Published: October 2019

The process of invasion, naturalization, dispersion and invasive activity of non-native woody species in 5 regional floras, 5 urban floras and over 30 floras of the protected areas is discussed. It has been established that 182 non-native species out of 95 genera and 45 families are currently at different naturalization stages in the spontaneous flora of Ukraine. In terms of life-forms, they may be divided as follows: trees – 41%, shrubs – 35%, trees/shrubs – 15%, lianas – 9%. Most species spread both via seed dispersal and the vegetative way – 56%, using only seed dispersal – 42%, only the vegetative way – 2%. According to the preliminary rating of species-wise invasive activity, 71 species (40%) have naturalized completely, among them 20 invasive species, including 12 transformer species, 29 potentially invasive species, and 22 naturalized species which demonstrate no invasive tendencies. The initial stages of invasion of 111 species are as follows: introduction – 9%, survival – 36%, adaptation of the reproductive sphere – 28%, establishment, formative of local populations – 27%. In terms of dispersion, non-naturalized species are divided as follows: rare – 45%, local – 16%, sporadic – 6%, unique – 12%, spreading under control beyond collections and expositions in botanical gardens and arboretums – 21%. Twelve transformer species, the greatest threat to local diversity, are Acer negundo, Ailanthus altissima, Amorpha fruticosa, Bupleurum fruticosum, Elaeagnus angustifolia, E. rhamnoides, Fraxinus ornus, Parthenocissus quinquefolia, P. vitacea, Robinia pseudoacacia, Rhamnus alaternus, Salix × blanda and 8 invasive proper species: Berberis aquifolia, Colutea orientalis, Daphne laureola, Prunus cerasifera, P. serotina, Quercus ilex, Viburnum tinus, Vitis vinifera. The list of alien species, most widespread in 50 regions of Europe, includes Robinia pseudoacacia (42 regions), Ailanthus altissima (40), Acer negundo (38), Prunus cerasus (34), Quercus rubra (34), Rosa rugosa (34), Prunus domestica (31). The mitigation of the impacts of these species on local biodiversity is possible via the restoration of local native plant communities, land use organization, strict selection of introduced species prior to the introduction, culture of planting management, preventive measures and extending awareness and sharing of information about plant invasions. Therefore, Ukraine’s spontaneous flora is notable for the active process of naturalization of non-native woody species with considerable involvement of invasive alien species. This is the first and preliminary evaluation of the invasive activity of woody species in Ukraine’s flora. The manifestations of the global tendency of increased involvement and invasive activity of alien woody species in domestic flora have been confirmed. These conclusions are also relevant for elaborating the system of preventive, containing and mitigating measures regarding plant invasions in Ukraine.

Zwraca uwagę, że w przygotowaniu homilii poza egzegezą biblijną i hermeneutyką liturgiczną ważna jest również analiza antropologiczna życia słuchaczy homilii. Jest to swoista egzegeza homilijna działania Ducha Świętego w Ludzie Bożym. W znakach czasów ujawnia się bowiem Jego inspiracja i działanie. Choć nie są one jakościowo równe z Pismem Świętym, są jednak specyficzną mową świata do Kościoła i swoistym głosem Bożym do Kościoła, wypowiadanym przez świat. Wyrażają potrzeby i oczekiwania aktualnego pokolenia wobec Boga. W związku z tym, postulując ewangeliczne rozeznawanie znaków czasów, zaproponowano paradygmat personalistyczno-chrystocentryczny, metodę i konkretne wyznaczniki tego procesu oraz wskazano wnioski wobec praktyki homilijnej i dydaktyki homiletycznej.
Ewangelizator napełniony Duchem Świętym. Formacja świadków Ewangelii w Zgromadzeniu Sióstr Benedyktynek Misjonarek

Apostołowie „zostali napełnieni Duchem Świętym, i zaczęli mówić obcymi językami, tak jak im Duch pozwalał” (Dz 2, 4). Towarzyszyły temu spektakularne znaki, takie jak gwałtowny wicher oraz tajemnicze języki ognia. Dokładnie tak, jak przepowiedział to Jezus, wydarzyło się coś niezwykłego, coś, co sprawiło, że życie uczniów radykalnie się zmieniło. Podstawą tego doświadczenia jest historyczny fakt krzyża i zmartwychwstania Jezusa. Dzieło ewangelizacji, podjęte przez benedyktynkę misjonarkę, potwierdza autentyczność życia chrześcijańskiego w Duchu Świętym, jakie stało się również udziałem apostołów i tych, którzy przyjęli dar Ducha Świętego. Dzięki temu benedyktynka misjonarka stała się świadkiem Chrystusa, i we wspólnocie Kościoła realizuje otrzymaną misję. Budowaniu historii zbawienia, w Duchu Świętym, służy formacja chrześcijańska. Świadomość daru chrztu świętego, wprowadzającego niejako przez „bramę” w nową jakość życia – życia według Ducha, sprawia, że każde działanie benedyktynki misjonarki jest uwielbieniem Boga, komunią z Nim i „źródłem” więzi z każdym człowiekiem.
Power and Conflict in the Public Realm: rethinking progressive visions of collaborative citizenship
Authors: Schutz Aaron
Published: October 2019

John Dewey's vision of education and of the school as a model for society was grounded in a commitment to collaboration. This view continues to inform the basic assumptions of progressive educators, especially in the USA. Collaboration in classrooms is offered as the basis and matrix
for collaboration beyond them, in the civic realm. But the civic realm is a realm of struggle, and to overemphasize collaboration miseducates students as to its reality. This article explores Saul Alinsky's critique of the Deweyan vision of civic action, with its alternative understanding
of the place of collaboration in civic engagement. For the powerless to be heard and heeded by the powerful, collective organization and skills for engaging in conflict in the public realm are key requirements.

Abstract: Nitrogen topdressing is essential for forage production, but the high cost of fertilizers stimulates the search for new technologies, such as the use of diazotrophic bacteria, which can fix the atmospheric nitrogen. To evaluate the potential of this technology in providing the amount of nitrogen requested by xaraés grass as topdressing, plants were fertilized at planting with an N rate of 100 kg ha-1, inoculated with strains of diazotrophic bacteria and Azospirillum brasilense, and compared with plants that received 100 kg ha-1 of N at planting and as topdressing during two periods of shoot growth (58 days in the first period and 26 days in the second period) in 20-dm3 pots. The data were subjected to analysis of variance and means compared by the Scott-Knott test at 5% significance. The leaf area of xaraés grass inoculated with strain UN42 was similar to that of plants that received nitrogen topdressing. However, grass biomass production was higher when nitrogen topdressing was applied. Plant inoculation with Azospirillum brasilense and strains UN16, UN17, UN21, UN33, UN49, and UN78 increased crude protein contents of xaraés grass when compared to nitrogen fertilization at planting without inoculation. However, grass inoculation with diazotrophic bacteria does not replace nitrogen topdressing completely.
Narrando histórias, coreografando emoções, no trabalho com o nascimento, a dor e a morte de crianças no hospital
Authors: Rangel Camila Butinholli , Gomes Maria Paula Cerqueira
Published: October 2019

Trata-se de uma pesquisa qualitativa baseada em narrativas produzidas por meio de entrevistas e oficinas. O estudo pretende demonstrar como profissionais de saúde de sete especialidades de uma UTI neonatal e pediátrica de um Hospital Público Municipal, no interior do Rio de Janeiro, identificam sinais de sofrimento no trabalho. Esses profissionais lidam com nascimento, dor e morte de crianças, mas não incluem essa experiência como parte integrante de seus cotidianos de trabalho. Aposta-se que o uso de narrativas seja um dispositivo capaz de incluir as dimensões da experiência dos quais tenta-se afastar, bem como produzir conhecimentos sobre a vida e a morte nos processos de trabalho.

Abstract: The aim of this study was to analyze aquatic oligochaete distribution in relation to water column physicochemical variables, structural environmental variation, and predominant substrates in the preserved Amazonian streams of the Saracá-Taquera National Forest (FLONA Saracá-Taquera), northwest Pará, Brazil. Oligochaetes are widely used as bioindicators for monitoring aquatic environments as they are very sensitive to pollution and environmental changes. Physicochemical and structural variables were measured from 100 stream segments in order to understand the distribution of oligochaetes in Amazonian streams. Biotic samples were collected using Surber samplers in three of the most predominant substrate types in each segment. PERMANOVA testing showed that there was a significant difference in the oligochaete community among some substrates, potentially caused by a difference in the abundance of the most common taxa. Canonical Correspondence Analysis showed that physical variables drive the distribution of oligochaetes in preserved Amazonian streams, as they determine the formation of different substrates along the stream, from the source to the mouth; favoring the presence of oligochaetes with more specific ecological needs in low-order streams, and the presence of oligochaetes capable of colonizing various types of substrates and deeper zones in high-order streams. These results suggest that water depth and channel width are the main drivers of aquatic oligochaete distribution along Amazonian streams, determining the formation of unstable and low-quality substrates and, consequently, the low colonization by oligochaetes in high-order streams; and more diverse and stable substrate formation in low-order streams, favoring the colonization by diverse taxa of aquatic oligochaetes in low-order Amazonian streams.
O envelhecimento da população brasileira: uma análise de conteúdo das páginas da REBEP
Authors: Dias Júnior Cláudio Santiago , Costa Carolina Souza , Lacerda Marisa Alves
Published: October 2019

Resumo O objetivo deste artigo é analisar, de maneira sistemática, o quanto e o que os demógrafos brasileiros têm produzido e refletido sobre o envelhecimento populacional brasileiro, tendo como base os artigos da REBEP (Revista Brasileira de Estudos de População). Essa idéia se baseou no trabalho de Watkins 30 (1993), que discutiu a maneira como as mulheres são cotejadas nos artigos publicados pela Demography. Nosso foco tratará o envelhecimento populacional como um processo demográfico, enfatizando os aspectos decorrentes desse processo na vida social. Para a realização deste trabalho, foram analisados todos os artigos publicados pela revista entre os anos de 1984 a 2003. A metodologia escolhida foi a análise de conteúdo. Apesar da subjetividade do método, podemos afirmar que a REBEP publicou poucos artigos cuja temática principal fosse o envelhecimento populacional e suas conseqüências. Durante os 20 anos de existência da REBEP, apenas oito trabalhos, entre artigos, resenhas e notas de pesquisa sobre envelhecimento, foram publicados sobre o tema.

Resumo Este trabalho teve como objetivo caracterizar o estado nutricional dos idosos cadastrados no Programa Municipal da Terceira Idade (PMTI) situado em Viçosa, Minas Gerais. A população estudada constituiu-se de 183 idosos com idade entre 60 e 90 anos, assistidos pelo PMTI de Viçosa. Os idosos foram avaliados pelo método antropométrico, utilizando-se peso, altura, circunferências da cintura e do quadril para calcular a relação cintura/quadril (RCQ) e o índice de massa corporal (IMC). O perfil nutricional do grupo apresentou uma bipolarização, com alta prevalência de sobrepeso (40,8%) e baixo-peso (15,1%). A freqüência de CC (circunferência da cintura) aumentada e de RCQ inadequada foi alta em ambos os sexos (61,4%), sendo significativamente maior nas mulheres. Os resultados encontrados apresentam uma situação preocupante dessa população, sendo necessário adotar medidas de controle e prevenção do sobrepeso, destacando-se o baixo-peso como importante fator de risco de mortalidade entre idosos.
