Depressão e bem-estar subjetivo em crianças e adolescentes: teste de modelos teóricos
Authors: Baptista Makilim Nunes , Filho Nelson Hauck , Cardoso Cassandra 
Published: January 2017

Embora sintomas de depressão e indicadores de bem-estar sejam tidos como teoricamente ortogonais, evidências sugerem, em contraste, uma correlação negativa entre eles. O presente estudo buscou testar diferentes modelos confirmatórios para explicar a relação entre sintomas depressivos e bem-estar subjetivo em crianças e adolescentes. Participaram 331 estudantes (M = 12,42 anos; DP = 1), que responderam ao Inventário de Depressão Infantil (CDI), à Escala Baptista de Depressão – versão infantojuvenil (EBADEP-IJ) e à Escala de Bem-Estar Subjetivo (EBES). O melhor ajuste ocorreu para um modelo bifator, em que indicadores relacionados à depressão carregaram positivamente em um fator geral, enquanto indicadores de bem-estar subjetivo carregaram negativamente, além de se conectarem positivamente a um fator específico de aspectos positivos. Os achados integram as perspectivas aparentemente excludentes de que a depressão e o bem-estar subjetivo são ou polos opostos de um contínuo, ou entidades independentes.
Pais encarcerados: narrativas de presos sobre a experiência da paternidade na prisão
Authors: Miranda Márcia Lepiani Angelini , Granato Tania Mara Marques 
Published: January 2017

Considerando o expressivo crescimento da população prisional brasileira e o fato do encarceramento impactar não apenas o indivíduo preso, mas também seus familiares, investigamos a experiência paterna de 41 presidiários cumprindo pena em uma penitenciária paulista. Optamos por uma abordagem qualitativa que utiliza uma Narrativa Interativa, seguida de uma discussão em grupo, para explorar os sentidos afetivo-emocionais que a experiência da paternidade pode tomar na prisão. Os filhos figuram como incentivo à mudança de vida do preso, além de serem referidos como principal suporte emocional nesta condição de vulnerabilidade. Sentimentos de culpa, impotência e arrependimento marcam o relato dos participantes, além da preocupação com o futuro dos filhos. Relações conjugais conflituosas e exigências institucionais contribuem para a fragilização do vínculo pai-filhos. Os achados deste estudo sinalizam os potenciais benefícios que o fortalecimento dos vínculos familiares reverte para o bem estar dos filhos e a reintegração social do preso.

Published: January 2017

The species composition of the vegetation in most regions of Angola has been poorly studied and most studies date back to the pre-independence era. In this study, we provide a detailed account of the woody flora of the Miombo woodlands and geoxylic grasslands of the Cusseque study site of “The Future Okavango” (TFO) project, situated on the Angolan Central Plateau. The checklist is based on a vegetation survey using vegetation plots of 1,000 m² and also includes records from botanical collections made elsewhere at the study site. In total, we documented 154 woody species belonging to 99 genera of 37 plant families in 100 km². The study represents the first comprehensive account of the woody vegetation of the area including all habitats and growth forms.
Las preposiciones en y a en sintagmas con nombre de objeto. Una descripción desde el enfoque cognitivo: el caso de 'volante' y 'timón'
Authors: Hernández Patricia C. 
Published: January 2017

El presente artículo aborda la aparente alternancia de las preposiciones en y a seguidas de los lexemas volante y timón en escenas espaciales que localizan una figura con respecto a una base u objeto de referencia. Postulamos que, si bien estos sintagmas preposicionales comparten una amplia gama de contextos, no evocan necesariamente la misma escena. Nuestro estudio propone una caracterización de su comportamiento semántico-pragmático desde una perspectiva cognitiva: sostenemos que (i) la construcción del sentido es un proceso holístico y (ii) las palabras son modos de acceso a marcos de interacción socialmente compartidos. Nuestra aproximación teórica se basa substancialmente en los conceptos de rol télico, marcos de interacción, zonas activas, conexiones metonímicas y metafóricas. Un estudio cualitativo de 671 enunciados arroja luz sobre las particularidades de cada expresión: los sintagmas preposicionales en el volante / timón pueden localizar tanto figuras animadas como inanimadas mientras que los SP al volante / timón requieren figuras animadas que mantengan una interacción pertinente con el objeto de referencia. Además, puede observarse que frecuentemente los sintagmas con el lexema timón dan lugar a proyecciones metafóricas.

<p>A systematic <em>ab initio</em> (DFT-GGA) study of adsorption of various oxygen species on graphene has been performed in order to find out general trends and provide a good starting point to analyze the oxidation of more complex carbon materials. Particular attention was paid to finding an appropriate supercell model. According to our findings, atomic O is characterized by stable adsorption on graphene and very strong adsorption on defective graphene. On the other hand, O<sub>2</sub> does not adsorb on graphene and is allowed to diffuse freely to the defect, where it is expected to dissociate into two strongly adsorbed O atoms. The obtained results were compared with available theoretical data in the literature and good agreement was achieved.</p><p> </p>

<p>A quantum theoretical approach, within the adiabatic approximation and taking into account a strong non-adiabatic correction via the resonant exchange between the fast mode excited states of the two moieties of the dimer. The intrinsic anharmonicity of the low-frequency mode through a Morse potential, direct and indirect damping, and a selection rule breaking mechanism for forbidden transitions, is applied to reproduce the υ<sub>X-H </sub>IR line shape of cyclic dimers of moderately H-bonded species in the crystalline phase. The results are used to gain an insight into the experimental spectral line shapes obtained by the transmission method. This approach fits satisfactorily the experimental line shape of 2-thiopheneacetic acid and predicts their evolution with isotopic substitution. Numerical calculations show that mixing of all these effects allows one to reproduce the main features of the experimental IR line shapes. </p>

La enfermedad de Huntington (EH) es una enfermedad neurodegenerativa devastadora, hereditaria, caracterizada por síntomas progresivos motores, cognitivos y psiquiátricos, los cuales aparecen mayormente durante la vida adulta. Su curso clínico produce consecuencias físicas, emocionales, cognitivas, sociales y económicas graves en el paciente y cuidadores. Su prevalencia a nivel mundial se estima en 7-10 por 100000 habitantes pero, en la zona del Valle de Cañete en nuestro país, se estableció en más de 40 por 100,000. Actualmente no existe cura para la EH; sin embargo, se dan opciones terapéuticas para el alivio de síntomas con el fin de mejorar la calidad de vida del paciente. Es en este rubro donde radica la importancia de los Cuidados Paliativos, definidos por la Organización Mundial de la Salud como un enfoque de atención que, mediante medidas de prevención y alivio del sufrimiento, asiste eficazmente a las personas enfermas y a sus familiares en el afronte de problemas asociados con enfermedades mortales. A pesar del impacto que genera esta patología en nuestra población, nuestro país carece de recursos suficientes para el tratamiento integral de los pacientes. Mejorar la atención al final de la vida es un reto moderno que requiere incrementar la formación de los profesionales de la salud y la comunidad, mayor financiación para la atención y desarrollo de políticas pertinentes.

Experimental Studies on Reinforced Concrete and Ferrocement Beams
Authors: Jayaramappa N. 
Published: January 2017

<div><p><em>Arch structures have been utilized through the ages, beginning in the ancient civilizations of Greece, Egypt and Rome, to present day with their common use in bridges. Arches are well known for the ability to carry loads spanning large areas. Also now a day’s Ferrocement is being used extensively for various applications where use of normal concrete is hard to fulfil the present day requirements. In this paper experimental studies are carried out to understand the flexural behaviour of Reinforced concrete beams of grade M20 with HYSD reinforcement and Ferrocement hollow beams of cement to sand ratio of 1:3 and water cement ratio of 0.4. A total of four beams were cast in which two are straight beams and another two are arched beams. In that two straight beam, one is reinforced concrete beam with minimum reinforcement and another one is Ferrocement hollow beam and in two arch beams, one is reinforced concrete beam and other is Ferrocement hollow beam. All beams are rectangular in cross-section of size 200 x 200 mm and the span length is 2500 mm. The arch beam is provided with a rise at centre of 0.8 m. The Ferrocement beam is made of mortar with hollow cross section using hexagonal wire mesh with thickness of 40 mm and all the specimens are cured for 28 days. Flexural tests are carried out on conventional RC beam and Ferrocement hollow beams for simply supported condition. The test results are presented in terms of load deflection behaviour, ultimate load, cracking load and crack pattern with respect to reinforced concrete beam and Ferrocement hollow beam.</em></p></div>
Yield and Nutritive Value of Cool‐Season Annual Forages and Mixtures Seeded into Pearl Millet Stubble
Authors: Villalobos Luis , Brummer Joe E. 
Published: January 2017

Core Ideas
Annual cool‐season forages with high biomass yields may be stockpiled for fall grazing.
Species composition was affected by the seeding rates of individual species used within the bulk seeding rate.
Controlling millet regrowth with herbicide prior to seeding resulted in greater establishment, yield, and nutritive value of the seeded cool‐season forages.
Annual forages can meet the requirements of beef cattle grazing during the fall and early winter.
Cool‐season annual forages can provide grazing for beef cattle during fall and early winter. The objective of this study was to evaluate yield and nutritive value of nine forage combinations seeded in early August into pearl millet (Pennisetum glaucum L.) hay stubble that was either sprayed or allowed to regrow. Grass species included spring triticale (×Triticosecale Wittmack), winter wheat (Triticum aestivum L.), and winter barley (Hordeum vulgare L.). Each grass was then combined with a brassica mixture {turnip [Brassicas rapa L. var. rapa], rape [Brassica napus L. var. napus], radish [Raphanus sativus var. oleifer Strokes], and hybrid Chinese cabbage [Brassica rapa L. chinensis) × Turnip]}. A legume mixture (hairy vetch [Vicia villosa Roth] and Austrian winter pea [Pisum sativum subsp. arvense L.]) was then added to the grass–brassica mixtures. All species and mixtures produced sufficient forage (3080–5580 kg dry matter [DM] ha−1) to be stockpiled for fall grazing. The millet and brassicas dominated yield and nutritive value of the unsprayed and sprayed mixtures, respectively. The concentration of neutral detergent fiber (aNDF) was greater in unsprayed than sprayed mixtures (510–579 and 229–246 g kg−1, respectively), but the concentrations of crude protein (CP) (169–180 and 185–202 g kg−1, respectively) and in vitro true digestibility (IVTD) (755–799 and 909–922 g kg−1, respectively) were less. The lesser nutritive value and yield potential associated with letting the millet regrow must be weighed against the extra inputs but greater yield potential and nutritive value when the regrowth is controlled prior to seeding.
Comparison of Weed Seedbanks in Different Rice Planting Systems

Published: January 2017

Core Ideas
Weed seedbanks were compared in three rice planting systems: machine‐transplanted rice, water direct‐seeded rice, and dry direct‐seeded rice.
Weed seedbanks were mainly distributed in soil within a depth of 10 cm.
Dry direct‐seeded rice tended to maintain larger seedbanks of sedges, grasses, and some upland weeds.
Water direct‐seeded rice contained the smallest weed seedbank overall.
Machine‐transplanted rice had larger seedbanks of broadleaf weeds and some traditional rice weeds.
Machine‐transplanted rice (Oryza sativa L.) (MTR), water direct‐seeded rice (WDSR), and dry direct‐seeded rice (DDSR) are three important alternatives to traditional manual transplantation of rice. Weed infestation is a pervasive problem in all rice planting systems. The weed seedbanks under different rice planting systems have seldom been compared. Thus, we sampled weed seeds in fields employing MTR, WDSR, and DDSR consecutively for at least 5 yr in Wujin County, eastern China. Seeds of 26 companion weed species of rice, comprising 16 families, were observed. Most weed seeds, 82.5% in MTR, 75.3% in WDSR, and 81.7% in DDSR, were distributed in soil 0‐ to 10‐cm deep. As soil depth increased, the seedbanks of total weeds, broadleaf weeds, grasses, and sedges all significantly decreased under the different rice planting systems, except for sedges under WDSR. The DDSR tended to maintain larger seedbanks of sedges and grasses, as well as some upland weeds, such as Digitaria sanguinalis (L.) Scop. and Eleusine indica Gaertn. The WDSR system contained the smallest weed seedbank overall but tended to have larger seedbanks of several weeds, such as Ammannia arenaria H. B. K. and Lindernia procumbens (Krock.) Philcox. Weedy rice and Cyperus difformis L. tended to maintain larger seedbanks in DSR fields. The MTR fields tended to have larger seedbanks of broadleaf weeds and some traditional rice weeds, with significantly lower richness of weed species in the seedbank. Therefore, to downsize the weed seedbank, WDSR or MTR should be employed rather than DDSR when possible. Moreover, the influences rotation of different rice planting systems on the weed seedbank merit more studies.

Forage sorghum has potential as alternative to corn silage in rotation with winter cereals.
Crop sensing is a promising approach for predicting end‐of‐season yields. Yield prediction is the first step in development of algorithms for sensor‐based N management.
To develop reliable algorithms for fertility management of forage sorghum in double crop rotations that account for timing, height of scanning and sensor orientation.
To evaluate which method of reporting of sensor measurements (NDVI, INSEYGDD, or INSEYDAP) gives the better prediction of yield.

Increasing home‐grown forage production is important for the dairy industry. Double cropping of forage crops like corn (Zea mays L.) silage with cereal rye (Secale cereale L.) or triticale (× Triticosecale spp.) can increase full‐season yield but could impact the length of the growing season for corn silage. Brown midrib (BMR) brachytic dwarf forage sorghum (Sorghum bicolor L.) has great potential as an alternative to corn silage in double crop rotations. Both winter cereals and forage sorghum require N management. Crop sensing is a promising approach for predicting end‐of‐season yields, the first step in development of algorithms for sensor‐based N management. Here we evaluated the impact of timing, sensor orientation and height of scanning, and the use of normalized difference vegetation index (NDVI) data vs. in‐season estimated yield (INSEY) on the ability of sensor data to predict yield of forage sorghum. Four trials with N rates ranging from 0 to 224 or 280 kg of N ha−1 at planting (site‐specific) were implemented in four replications in 2014–2015. Scanning took place from 19 to 69 d after planting (DAP). Yield was measured at soft dough (111–124 DAP). Sensor height and orientation impacted the NDVI prior to 45 DAP but not once the canopy was fully developed. Most accurate yield predictions were obtained 49 DAP when the sorghum was 0.76 m tall. The INSEY expressed as plant growth per day (INSEYDAP) best correlated with yield. We conclude that crop sensors can be used to accurately predict forage sorghum yields.
Recovery and Relative Influence of Root, Microbial, and Structural Properties of Soil on Physically Sequestered Carbon Stocks in Restored Grassland
Authors: Scott Drew A. , Baer Sara G. , Blair John M. 
Published: January 2017

Core Ideas
We found that cultivated and never‐cultivated grassland soils had 12 and 59% of the total C pool sequestered in the micro‐within‐macro aggregate fraction, respectively.
The micro‐within‐macro aggregate C increased at a rate of 27 g C m–2 yr–1 across the restoration chronosequence; 50% of total C was in this physically protected fraction after 35 yr of restoration.
This is the first study to use structural equation modeling to explain soil C stocks in the micro‐within‐macro aggregate fraction. The model explains 98% of the variance in sequestered soil C, with microbial composition representing the strongest causal influence, followed by soil structure.
Managing soil to sequester C can help mitigate increasing CO2 in the atmosphere. To maximize this ecosystem service, more knowledge of factors influencing C sequestration is needed. The objectives of this study were to (i) quantify recovery of the roots, microbial biomass and composition, and soil structure across a chronosequence of grassland restorations and (ii) use a structural equation model to develop a data‐based hypothesis on the relative influence of physical and biological soil properties on the soil C aggregate fraction diagnostic of sequestered C. Belowground plant biomass and tissue quality (C/N ratio), soil microbial biomass C, phospholipid fatty acid (PLFA) concentrations, soil structure, and soil C stocks in the bulk soil and each aggregate fraction were quantified from a cultivated field, prairies restored for 1 to 35‐yr (n = 6), and a never‐cultivated (native) prairie. Root biomass, microbial biomass C, arbuscular mycorrhizal fungi (AMF) PLFA biomass across the chronosequence increase to resemble native prairie following 35 yr of restoration. Many aspects of soil structure (i.e., bulk density, proportional mass of aggregate fractions, and aggregate mean weighted diameter) and the distribution C among soil fractions, including C in the micro‐within‐macro aggregate fraction (sequestered C), also became representative of native prairie within 35 yr of restoration. Total soil C stock and physically protected C increased at a similar rate (23 and 27 g C m‐2 yr‐1) respectively, across the chronosequence. After 35 yr of restoration, 50% of the total C pool was physically protected. The structural equation modeling developed by these data hypothesizes that microbial biomass C and AMF biomass (microbial composition) have the strongest causal influence on physically protected C. This model needs to be tested using independent sites to achieve greater inference.
