Comportamento de variedades de cana de açúcar no arenito de Bauru

Sixteen varieties of sugar cane were tested in a sandy soil of "arenito de Bauru" type at the Usina Miranda, Presidente Alves. Three harvests were made (plant cane, 1st and 2nd stubble). Cane and sugar yields of the first harvest alone and of the three harvests together were analysed statistically and gave the following indications: 1)  Of the 16 varieties tried, Co.419, C.B.40...

Adubação da cana-de-açúcar. XIII - Estudo conjunto de experiências com diversos fosfatos realizadas entre 1950 e 1963

Based on experiments conducted from 1950 up to 1963 on different soil types of the State of São Paulo, the authors studied the efficiency of several phosphorus carriers, for the fertilization of sugar cane, when applied in the presence of NK at the rate of 100 kilograms of total P2O5 per hectare. The areas used were all deficient in phosphorus with pH varying between 4.5 and 6.3...

Adubação da cana-de-açúcar. X - Experiências com diversos fosfatos (1959-60)

Three experiments were conducted in 1959-60 in the State of São Paulo to study the efficiency of different sources of phosphorus for the production of sugar cane, using 50, 100 and 150 kilograms of total P2O5, per hectare in the presence of NK. Phosphorus significantly increased the yields in all of the experiments, in one of them, on «terra-roxa-misturada» type of soil, the...

Adubação da cana-de-açúcar. XI - Experiências com diversos fosfatos (1961 a 1963)

Five experiments were conducted in the State of São Paulo to study the efficiency of different sources of phosphorus for the production of sugar cane on three types of soil, using 50, 100 and 150 kilograms of total P2O5 per hectare in the presence of NK. The soil pH varied from 4.8 to 5.6. Phosphorus significantly increased the yields in all of the experiments. As an average of...

In-situ evaluation of dye adsorption on TiO2 using QCM

We measured the adsorption characteristics of two organic dyes; triphenylamine-cyanoacrylic acid (TPA-C) and phenoxazine (MP13), on TiO2, directly in a solution based on quartz crystal microbalance (QCM). Monitoring the adsorbed amount as a function of dye concentration and during rinsing allows determination of the equilibrium constant and distinction between chemisorbed and...

Reshaping the epigenetic landscape during early flower development: induction of attractor transitions by relative differences in gene decay rates

A Minimal Regulatory Network of Extrinsic and Intrinsic Factors Recovers Observed Patterns of CD4+ T Cell Differentiation and Plasticity

CD4+ T cells orchestrate the adaptive immune response in vertebrates. While both experimental and modeling work has been conducted to understand the molecular genetic mechanisms involved in CD4+ T cell responses and fate attainment, the dynamic role of intrinsic (produced by CD4+ T lymphocytes) versus extrinsic (produced by other cells) components remains unclear, and the...

SEOM Clinical Guideline of management of soft-tissue sarcoma (2016)

Soft-tissue sarcomas are uncommon and heterogeneous tumors of mesenchymal origin. A soft-tissue mass that is increasing in size, greater than 5 cm, or located under deep fascia are criteria for suspicion of sarcoma. Diagnosis, treatment, and management should preferably be performed by a multidisciplinary team in reference centers. MRI and lung CT scan are mandatory for local and...

Molecular Evolution and Patterns of Duplication in the SEP/AGL6-Like Lineage of the Zingiberales: A Proposed Mechanism for Floral Diversification

The diversity of floral forms in the plant order Zingiberales has evolved through alterations in floral organ morphology. One striking alteration is the shift from fertile, filamentous stamens to sterile, laminar (petaloid) organs in the stamen whorls, attributed to specific pollination syndromes. Here, we examine the role of the SEPALLATA (SEP) genes, known to be important in...

Tetramer formation in Arabidopsis MADS domain proteins: analysis of a protein-protein interaction network

Background MADS domain proteins are transcription factors that coordinate several important developmental processes in plants. These proteins interact with other MADS domain proteins to form dimers, and it has been proposed that they are able to associate as tetrameric complexes that regulate transcription of target genes. Whether the formation of functional tetramers is a...

New Genes in Traditional Seed Systems: Diffusion, Detectability and Persistence of Transgenes in a Maize Metapopulation

Gene flow of transgenes into non-target populations is an important biosafety concern. The case of genetically modified (GM) maize in Mexico has been of particular interest because of the country’s status as center of origin and landrace diversity. In contrast to maize in the U.S. and Europe, Mexican landraces form part of an evolving metapopulation in which new genes are subject...
