Microbial activity in the rhizosphere is essential for nutrient cycling, which can contribute to soil fertility and plant growth. This work aimed to evaluate the effects of two biological control agents (Trichoderma sp. and Beauveria sp.) on the functional groups of microorganisms in the soybean (Glycine max) rhizosphere and plant growth. The experiment was carried out in a greenhouse, and five replicates with one plant per pot (1000 mL), containing a mixture of soil: sand (4:1), were harvested and microbial communities evaluated at 7, 21, 45 and 60 days after soybean germination. The populations of heterotrophic bactéria (HBP), saprophytic fungi (SFP), fluorescent pseudomonads (PFP) and the functional groups of microorganisms related to carbon cycling [proteolytics (PP), amylolytics (AP) and cellulolytics (CP)], nitrogen cycling [dry weight of nodules (DWM)], and phosphorus cycling [AM fungi colonization (AM)] were estimated. A soil sample (1 g) was taken from the homogenized rhizosphere soil to estimate the culturable microbial community size. Samples were suspended in 9 mL of sterile saline (0.85%) and aliquots (50 ?L) of ten-fold dilutions spread on the respective culture medium. Plates were incubated at 28 °C and CFU were counted. The results showed that biological controls agents such as Trichoderma sp. and Beauveria sp. presented diferente effects on microbial community and Rhizophagus clarus colonization. Trichoderma sp. had positive influence on plant growth and soil microbial community, except for AM fungi. However, Beauveria sp. showed no significant differences in all evaluations, including plant growth.

The use of rootstocks originated from sexual propagation results in serious problems for peach culture, being vegetative propagation an important alternative to minimize these problems partially. Among vegetative propagation methods, the use of mini-cuttings constitutes an innovation against the conventional mini-cutting method, which, in some species, have promoted an increase in productivity, uniformity and rooting percentage. Thus, the objective of the present work was to evaluate the viability of Japanese apricot propagation through herbaceous mini-cuttings, by testing different concentrations of IBA (0, 1.000, 2.000 e 3.000 mg.L-1) and types of mini-cuttings (apical, median and basal), in a completely randomized design with four replications. Prepared with two buds and a leaf cut in half, with two lesions on the basis, they were immersed in IBA solution, for 10 seconds, and placed in transparent, articulated plastic packages with vermiculite growing medium. Next, they were placed in a greenhouse under controlled temperature. Sixty days after installation, the percentage of rooted mini-cuttings, number and length of the three largest roots were evaluated. During rooting, the apical, median and basal mini-cuttings showed higher percentage using 1.000 mg.L-1 of IBA.

Nitrogen fertilization associated to the application of molybdenum (Mo) can increase grain yield in maize crops. Therefore, the objective of this study was to evaluate the effect of molybdenum application forms associated to topdressing nitrogen fertilization on production components and maize crops grain yield. The experiment was conducted with the cultivar Pioneer® 30F53H, under a randomized blocks experimental design, with subdivided parcels and four replications. Four forms of Mo applications were evaluated in each parcel: control (without Mo); seeds treatment (40 g ha-1 Mo); foliar treatment (40 g ha-1 Mo); seeds treatment (20 g ha-1 Mo) plus foliar treatment (20 g ha-1 Mo), using potassium molybdate as Mo source. The sub-parcels received four dosages of nitrogen (N), in topdressing (0, 80, 160 and 240 kg ha-1 N), in the form of urea. The experiment evaluated plant height, ear insertion height, stem diameter, number of grains per ear, 100 grains mass and grain yield in maize crops. The increase in N dosages in topdressing increases plant height, ear insertion height, stem diameter, number of grains per ear, 100 grains mass and maize crop grains yield. The application of molybdenum improves N absorption by maize crops. When applied via seeds treatment, Mo brings better results to foliar application in partial or total dosages.

Brazil offers great perspectives for the expansion of blueberry (Vaccinium spp.) cultivation areas, mainly in family agriculture areas. Among the factors that limit the expansion of this culture is the difficulty to propagate some cultivars. Thus, the objective of this work was to evaluate the use of different substrates and concentrations of indolebutyric acid (IBA) for blueberry cuttings cvs. Woodard rooting, to optimize seedlings production system. The experimental design was totally randomized in a 3X3 factorial scheme, with five replications of 10 cuttings, and included the following factors: types of substrate (carbonized rice husk, vermiculite medium granules and coconut fiber) and IBA concentrations (0, 1,000 and 2,000 mg L-1). After 150 days, survival percentage was superior for carbonized rice husk, with no influence of IBA concentration. In regards to rooting, the carbonized rice husk and coconut fiber provided better results, being IBA application favorable for this variable. It was concluded that 'Woodard' blueberry can be propagated by herbaceous cuttings, using preferentially carbonized rice husk and application of 1,000 mg L-1 IBA is recommended for rooting of softwood cuttings.

The understanding of the genetic control involved in characters of agronomic interest is of extreme importance to breeders aiming at planning procedures for breeding programs. Thus, the objective of this work was to study genetic aspects related to earliness and grain yield found in the initial generations of soybean, twice each year. The study evaluated six soybean parentes (MSOY6101, RSF6563IPRO, TMG123RR, SYN9078RR, TMG801 and MSOY9144RR) and their 15 F1´s in a greenhouse, during winter and summer. A second experiment conducted at Prof. Diogo Alves de Melo experimental field, located on the UFV campus, in Vicosa-MG, during the 2014/2015 agricultural year assessed parents and their segregating populations (F2). In all experiments, information were collected from individual plants. Results showed that both additive and dominance effects were important for the genetic control of soybean earliness and grain yield. Number of days to flowering and maturation and grain yield for the F1 and F2 generations, in winter and summer, is determined by dominant alleles. In regards to the studied characters, there was partial dominance mainly for the F1 generation and overdominance for the F2 generation. Parents MSOY6101 and RSF6563IPRO showed greater concentration of favorable alleles for flowering and maturation time reduction, and parents TMG123RR and SYN9078RR for grain yield. Parents TMG801 and MSOY9144RR gave the best contribution to cycle retardation for the F2 generation.

A eficácia na produção de plântulas de maracujá-amarelo (Passiflora edulis Sims e F. flavicarpa Deg) pode ser afetada pela germinação irregular, devido, principalmente, a um curto período de dormência das sementes, bem como ao uso do substrato errado. Assim, o objetivo deste trabalho foi avaliar o efeito de três temperaturas de armazenamento e três substratos durante o desenvolvimento inicial de plântulas de maracujazeiro amarelo. O experimento foi conduzido em casa de vegetação agrícola na Universidade Federal de Pelotas, RS. Após a retirada da mucilagem e secagem, as sementes foram acondicionadas em embalagens de papel Kraft e armazenadas a 5 ºC, 10 ºC e temperatura ambiente (18 ± 0,6 ºC) por 15 dias. Em seguida, eles foram cultivados em fibra de coco Amafibra®, casca de arroz carbonizada e S-10Beifort®. Sementes mantidas a 18 ºC apresentaram menor comprimento da raiz sem diferença entre os armazenados a 5 ºC. Não houve efeito da temperatura na emergência, comprimento da parte aérea, número de folhas e biomassa seca da parte aérea e das raízes. A maior porcentagem de germinação foi encontrada no substrato da casca de arroz carbonizada; no entanto, com exceção do maior comprimento radicular e da biomassa seca da parte aérea e das raízes, o desenvolvimento das plantas foi superior com os demais substratos. Assim, a utilização de temperatura de 10 ºC durante o armazenamento, bem como fibra de coco e S-10 Beifort® como substratos são as melhores recomendações para melhorar a emergência e desenvolvimento inicial do maracujá-amarelo. com exceção do maior comprimento radicular e da biomassa seca da parte aérea e das raízes, o desenvolvimento da planta foi superior com os demais substratos. Assim, a utilização de temperatura de 10 ºC durante o armazenamento, bem como fibra de coco e S-10 Beifort® como substratos são as melhores recomendações para melhorar a emergência e desenvolvimento inicial do maracujá-amarelo. com exceção do maior comprimento radicular e da biomassa seca da parte aérea e das raízes, o desenvolvimento da planta foi superior com os demais substratos.

Published: July 2019

The expansion of Brazilian cherry tree cultivation is affected by propagation difficulties and slow seedling production development. The cuttings and minicuttings technique is an alternative that offers several advantages, and it proved to be highly promising for many fruit tree species. Minicuttings taken from a clonal garden were rooted in 22 x 14 x 10 cm plastic boxes containing vermiculite, at IAB concentration of 2.000 mg.L-1. The experimental design was totally randomized with eight treatments (cultivation weeks), with four replications, with five minicuttings each. They were evaluated eight times (once a week), for a period of two months. The following variables were analyzed: number of swollen minicuttings, rooted minicuttings and minicuttings with roots longer than 1 cm. From the third week onwards, rooting was positive, with 70% of rooted minicuttings and 5% with swellings. In the fourth evaluation, 55% already showed roots longer than one centimeter, with a mean of 2.66 cm, five with roots emergence and three with swellings. In general, in seven weeks’ time the minicuttings showed efficient root development and were ready to be transplanted to plastic bags to develop quality seedlings.

Oil and fatty acid profile of seeds of soybean cultivars and their relationship with biodiesel and feeding
Authors: Del Águila Ricardo
Published: July 2019

The aim of this study was to evaluate the fatty acid profile in soybean cultivars from northeastern Brazil, materials developed primarily to achieve a minimum level of oil and protein. The purpose is to serve as to warn about the need to modify fatty acids profiles to enhance both the oil for human consumption and that used in biodiesel production. Results showed the predominance of linoleic acid (average 50.1%) followed by oleic acid (27.9%), palmitic acid (11.97%), linolenic acid (6.68%) and stearic acid (3.38%) in the composition of fatty acids. Such condition makes soybean oil less competitive for both human consumption (for its high content of saturated fatty acids) and the biodiesel industry (problems with oxidative stability and flow in the cold). Considerations are also made on conventional and modern techniques to overcome these drawbacks.

Published: July 2019

In vitro cultivation is a highly important biotechnological method widely used for the production of orchid seedlings, but it is necessary to study the suitability of the nutrients used in different kinds of formulation, as the nutritional requirement varies according to the species. The objective was to evaluate different concentrations of iron in the in vitro cultivation of Schomburgkia crispa Lindl seedlings. Seedlings were obtained from seeds germinated in vitro. Modified MS culture medium was used with half of the macronutrient concentration. The micronutrients were added according to the original formulation, except for the iron which was added from a stock solution of FeEDTA (FeSO4.7H2O: 5.6 g L-1 and EDTA: 7.48 g L-1) at 0.0; 2.5; 5.0; 7.5; 10.0 and 12.5mL L-1. At 200 days after seedling transplantation, shoot height, root length, number of leaves, shoot number, leaf length, leaf width, aerial and root dry mass, chlorophyll a, b and carotenoids content were evaluated. A completely randomized design was used, with six treatments and ten replicates of five seedlings. Regression analysis was performed at 5% of significance. The increase in iron concentration caused a reduction in root length and an increase in the number of leaves and shoots. The concentration of 4.13 mL L-1 of FeEDTA was the one that provided the best in vitro growth of S. crispa plants. High concentrations of iron caused a reduction of initial development, but stimulated an increase in the number of shoots.

The no-tillage system requires a higher use of herbicides to control weeds before sowing, increasing the concern over the effect that such products might have on the environment. However, few studies reporting the influence of glyphosate on soil microorganisms are available in the literature. The aim of this work was to evaluate the effect of two formulations of glyphosate on functional groups of microorganisms in soybean rhizosphere. The experiment was performed in a greenhouse, and the treatments were the isopropylamine salt and the ammonium salt of glyphosate at the maximum and twice the maximum allowed dose. The control treatment had no application. The populations of soil bacteria, fungi, actinomycetes, fluorescent pseudomonas, cellulolytics, amylolytics, proteolytics and free-living N-fixing were determined by plate counts on selective media. Plant root dry weight, shoot dry weight and the number and dry weight of nodules were determined. The application of herbicides had little effect on the populations of microorganisms, as well as on plant growth. Nevertheless, the interactions among some populations of microorganisms and between these and the plant were influenced by the formulation of the glyphosate applied.

Neglected Glyphosate-resistant (GR) crops are common in agro-ecosystems mainly due to its benefits of weed management. However, the effect of GR crops on soil ecosystem and on non-target soil organisms need to be monitored. The effect of two transgenic soybeans GR on soil microorganisms, soil enzymes, microbial biomass and plant growth were evaluated. The experimental design was conducted as factorial arrangement with two GR soybean varieties, the Londrina (RR 59) and its near isogenic non-GM 59 Londrina called VAR 1; the second was Valiosa soybean (RR Conquista) and its near isogenic non-GM Conquista - Uberaba soybean called VAR 2. The plants were inoculated with arbuscular mycorrhiza fungi and rhizobia. The results showed that significant differences were observed among GM plants and their parental non-GM only for N biomass, AM colonization and cellulase activity. The presence of AM fungi had great influence on the functional groups of microorganisms while some enzymes activity decreased.

Blueberry (Vaccinium spp.), much appreciated for its exotic flavor and nutraceutical properties, can be consumed in natura and in beverages such as nectar and juice. The aim of this study was to evaluate the chemical characteristics and the acceptance of commercial nectar and blueberry juice elaborated by the steam dragging method. The work was carried out in August of 2016, at the Universidade Federal de Pelotas, Pelotas (RS). The experimental design was in a uniform scheme, with two levels: commercial nectar and juice elaborated with the combination of fruits of cultivars Bluegem and Powderblue. Soluble solids content, titratable acidity and the pH of the samples were evaluated. For the sensorial analysis, a panel of fifty-five judges evaluated attributes such as color, aroma, flavor, body and global acceptance, using a nine-point hedonic scale. Regarding the chemical analyzes, there was a statistical difference for total soluble solids content and the nectar showed the highest content. In the sensory analysis, the juice elaborated with ‘Bluegem’ and ‘Powderblue’ obtained the highest mean for color, while for the flavor and body attributes, the preference of the judges for the nectar was verified. However, both had good overall acceptance, with scores between 7.52 and 7.62. Thus, acceptance of both nectar and juice was considered satisfactory by the evaluators.

Communication needs is crucial due to the progress and development of data communication technology that is growing rapidly. In meeting the needs of data communication technology must be wise in choosing an Internet Service Provider (ISP) which we will use. Using two or more ISP can be the solution to meet the needs of the internet at the Office. Load balancing is one of the routing techniques can take advantage of some of the ISP to be used simultaneously or if other ISP backing up each other down or troubled. However, there are a variety of methods that can be used, one of which is the method Per Connection Classifier (PCC). PCC can be used to classify the traffic connection through router mikrotik into several groups. So that the router will remember the path that passed early traffic connections and on subsequent packets that are still associated with the connection will initially passed on the same lines as well. Based on the research results show that the proposed load balancing techniques make the burden of traffic on each ISP or gateway will be in balance so that the bandwidth usage for more efficient and capable of accelerating the network connection the Internet.  In addition the proposed techniques help network connection failover internet connection problems occur in order not to fail or a link down on one of the ISP.

Kebutuhan komunikasi sangat penting seiring dengan kemajuan dan perkembangan teknologi komunikasi data yang semakin berkembang pesat. Dalam memenuhi kebutuhan akan teknologi komunikasi data, administrator jaringan harus bijak dalam memilih Internet Service Provider (ISP) yang akan kita gunakan. Menggunakan dua ISP atau lebih dapat dijadikan solusi untuk memenuhi kebutuhan internet. Load balancing merupakan salah satu teknik routing yang dapat memanfaatkan beberapa ISP untuk dapat digunakan secara bersamaan atau saling membackup jika ISP lainnya down atau bermasalah. Ada berbagai metode yang dapat digunakan, salah satunya adalah metode Per Connection Classifier (PCC). PCC dapat digunakan untuk mengelompokan  trafik koneksi  yang melalui router mikrotik menjadi beberapa kelompok, sehingga router akan mengingat jalur yang dilewati diawal trafik koneksi dan pada  paket-paket selanjutnya  yang  masih  berkaitan  dengan  koneksi awalnya akan dilewatkan pada jalur yang sama juga. Hasil penelitian menunjukkan bahwa teknik load balancing yang diusulkan menjadikan beban traffic pada masing-masing ISP atau gateway seimbang sehingga dalam pemakaian bandwidth lebih efisien dan mampu mempercepat koneksi jaringan internet.  Selain itu diusulkan pula teknik failover yang membantu koneksi jaringan internet agar tidak terjadi koneksi gagal atau link down pada salah satu jalur ISP.

Published: July 2019

The ultrafast optical response of the magnetic compound Bi2FeMnO6 (BFMO) is studied through 100–300 K by means of ultrafast transient reflectivity spectroscopy. By using differing pump energy, the optical low spin (LS) transition and high spin (HS) transition in this compound are distinguished as the temperature varies. This charge transfer transition is shown to be spin-dependent and element selected. The ultrafast spin-lattice coupling time also shows the element selected feature, which illustrated the two independent magnetic phase transitions to the antiferromagnet (AFM) Mn–O–Mn and the ferrimagnet (FIM) Mn–O–Fe order, respectively.
Atmospheric Pressure Plasma-Treated Carbon Nanowalls’ Surface-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (CNW-SALDI-MS)

Published: July 2019

Carbon nanowalls (CNWs), vertically standing highly crystallizing graphene sheets, were used in the application of a surface-assisted laser desorption/ionization time-of-flight mass spectrometry (SALDI-TOF-MS). The CNW substrates solved the issues on interferences of matrix molecules and alkali metal addition ions in low-weight molecule detection. Before SALDI sample preparations, the hydrophobic CNW was treated by atmospheric pressure plasma for exposing hydrophilicity to the CNWs’ surface. Detection of water soluble amino acids, arginine, was demonstrated.

Published: July 2019

Cryptococcal meningitis persists as a significant source of morbidity and mortality in persons with HIV/AIDS, particularly in sub-Saharan Africa. Despite increasing access to antiretrovirals, persons presenting with advanced HIV disease remains common, and Cryptococcus remains the most frequent etiology of adult meningitis. We performed a literature review and herein present the most up-to-date information on the diagnosis and management of cryptococcosis. Recent advances have dramatically improved the accessibility of timely and affordable diagnostics. The optimal initial antifungal management has been newly updated after the completion of a landmark clinical trial. Beyond antifungals, the control of intracranial pressure and mitigation of toxicities remain hallmarks of effective treatment. Cryptococcal meningitis continues to present challenging complications and continued research is needed.
A New Class of 2q-Point Nonstationary Subdivision Schemes and Their Applications

Published: July 2019

The main objective of this study is to introduce a new class of 2 q -point approximating nonstationary subdivision schemes (ANSSs) by applying Lagrange-like interpolant. The theory of asymptotic equivalence is applied to find the continuity of the ANSSs. These schemes can be nicely generalized to contain local shape parameters that allow the user to locally adjust the shape of the limit curve/surface. Moreover, many existing approximating stationary subdivision schemes (ASSSs) can be obtained as nonstationary counterparts of the proposed ANSSs.
Practical Sparse Matrices in C++ with Hybrid Storage and Template-Based Expression Optimisation
Authors: Sanderson Conrad , Curtin Ryan
Published: July 2019

Despite the importance of sparse matrices in numerous fields of science, software implementations remain difficult to use for non-expert users, generally requiring the understanding of the underlying details of the chosen sparse matrix storage format. In addition, to achieve good performance, several formats may need to be used in one program, requiring explicit selection and conversion between the formats. This can be both tedious and error-prone, especially for non-expert users. Motivated by these issues, we present a user-friendly and open-source sparse matrix class for the C++ language, with a high-level application programming interface deliberately similar to the widely-used MATLAB language. This facilitates prototyping directly in C++ and aids the conversion of research code into production environments. The class internally uses two main approaches to achieve efficient execution: (i) a hybrid storage framework, which automatically and seamlessly switches between three underlying storage formats (compressed sparse column, red-black tree, coordinate list) depending on which format is best suited and/or available for specific operations, and (ii) a template-based meta-programming framework to automatically detect and optimise the execution of common expression patterns. Empirical evaluations on large sparse matrices with various densities of non-zero elements demonstrate the advantages of the hybrid storage framework and the expression optimisation mechanism.

A necessidade do uso de fórmulas de estimativas de massa corporal se torna constante por diversos fatores que impossibilitam os pacientes a se colocarem de pé. Rabito e outros, em 2006, propuseram uma fórmula para estimativa de massa corporal com intuito de atender à população brasileira. Baseado nesta nova fórmula, o objetivo do presente estudo foi verificar a validade da fórmula de Rabito e outros (2006), realizando as medidas da circunferência abdominal em três posições diferentes. A amostra constitui-se de 60 pacientes deambulantes, e para o cálculo da fórmula de estimativa de massa corporal foram realizadas as medidas da circunferência do braço, circunferência da panturrilha e a circunferência abdominal, realizada com o paciente em três posições: em pé, em decúbito dorsal e sentado.  Os pacientes foram divididos por estado nutricional, através do índice de massa corporal, as massas corporais estimadas foram analisadas estatisticamente com a massa corporal real do paciente quantificada pela balança. Os resultados demonstraram valores estatisticamente semelhantes entre a massa corporal estimada e a massa corporal real em pacientes desnutridos em qualquer posição avaliada. Para pacientes eutróficos e com sobrepeso/obeso, a fórmula se mostrou eficiente para predição da massa corporal real apenas quando sentados. Estes achados podem levar a acreditar que o aumento da massa corporal pode influenciar negativamente na aplicabilidade do método nesta posição. Sugere-se a utilização da fórmula de estimativa de massa corporal proposta por Rabito e outros exclusivamente com o paciente sentado, por demonstrar valores semelhantes, independentemente do diagnóstico de estado nutricional.

Published: July 2019

O objetivo do estudo foi avaliar a insatisfação corporal entre os adolescentes, assim como os fatores associados. Avaliou-se 345 adolescentes de 10 a 14 anos. Foram aferidas as variáveis: peso, altura, circunferência da cintura, circunferência braquial, percentual de gordura, glicemia de jejum, triglicerídeos, colesterol total, maturação sexual e pressão arterial. A imagem corporal foi avaliada por meio da escala de imagem corporal. Foram realizados os testes t de Student ou Kruskal Wallis, calculou-se a Razão de Prevalência e os fatores associados à insatisfação corporal foram verificados por regressão de Poisson, para avaliar a adequação do modelo final, utilizou-se o teste de Qui-quadrado. Observou-se que 32,6% dos adolescentes apresentavam excesso de peso, desses, 13,1% foram classificados como obesos, segundo o IMC por idade. Apenas o percentual de gordura corporal foi estatisticamente diferente entre os sexos. A prevalência de insatisfação foi elevada (sexo feminino: 81,02% e masculino: 75,62%) e apresentou associação, em ambos os sexos, com o IMC, percentual de gordura corporal e circunferência da cintura. Nas meninas, também foi obtida associação com a glicemia. Já nos meninos, com a circunferência braquial e circunferência muscular braquial. Após ajuste do modelo a insatisfação manteve-se associada no sexo feminino com as variáveis: circunferência da cintura e glicemia. Nos meninos, com a gordura corporal e IMC. Concluiu-se que apesar da maioria apresentar o peso adequado, muitos adolescentes estavam insatisfeitos com seus corpos. Os achados também apontam que essa insatisfação atinge ambos os sexos e idades.

Objetivou-se avaliar o consumo de alimentos in natura ou minimamente processados na dieta de crianças de 0 a 24 meses, que estejam em alimentação complementar. Tratando-se de um estudo transversal realizado durante o período de maio a julho de 2016, com os responsáveis por lactentes de 0 a 24 meses, frequentadores de 5 UAPS das regiões central e oeste do município de Juiz de Fora- MG. Foram coletados dados socioeconômicos e dados referente ao consumo alimentar, através de um questionário semiestruturado de frequência alimentar que contemplava questões sobre o consumo de alimentos in natura ou minimamente processados usualmente ingeridos pelo público alvo.  Utilizou-se o programa SPSS 19.0 para proceder as análises estatísticas. O nível de significância adotado foi de 5%. A amostra foi constituída por 112 indivíduos, cuja mediana de idade era de 13 (1-24) meses, desses, 50% eram do sexo feminino. As famílias apresentaram renda mediana de 2 (1-5) salários mínimos. Foi constatado que 42% e 20% dos lactentes não consomem carnes e verduras diariamente. As crianças que não consomem verduras diariamente, apresentaram mediana de idade maior do que aquelas que consomem diariamente. Também foi encontrado uma variação do consumo de acordo com a renda familiar, e as crianças que consomem frutas, legumes e verduras diariamente, apresentam mediana de renda maior do que aquelas que não consomem tais alimentos diariamente.  Os resultados encontrados reforçam a necessidade de ações efetivas para estimular o consumo de alimentos in natura ou minimamente processados, entre os lactentes.
