A percepção da arquitetura através da cor: um estudo de caso da cor aplicada no complexo do centro Dragão do Mar de arte e cultura em Fortaleza/CE

Este trabalho é uma pesquisa sobre a cor, suas teorias, seu processo de percepção pelo ser humano e sua aplicabilidade na arquitetura. O estudo de caso foi realizado no entorno do Centro Dragão do Mar de Arte e Cultura, localizado na cidade de Fortaleza, Ceará, cujo processo de restauração se iniciou pelo projeto cromático, através do movimento Cores da Cidade, proporcionando um novo espaço urbano multicolorido. Resgata-se um pouco da história das cores através de uma abordagem sobre as teorias elaboradas por diversos estudiosos do tema ao longo dos anos, considerando seus aspectos físicos, químicos e psicológicos. Além disso, é apresentado um item indispensável para a leitura de projetos: a percepção. Recorrer às principais abordagens feitas sobre este tema é importante para dispormos de ferramentas necessárias a uma boa compreensão do projeto selecionado, a fim de entendermos como a cor participa do processo de concepção do mesmo, e como atua perante os usuários e observadores no espaço construído. A idéia foi trabalhar a cor situando-a num contexto: o contexto da arquitetura. Qual seu real papel ao constituir um ambiente construído? Será mesmo real ou depende do emocional de cada um? Como perceber a arquitetura através das cores? Estas e outras perguntas guiaram as buscas para a elaboração deste trabalho

Períodos de interferência das plantas daninhas em algodoeiro de fibra colorida ‘BRS Safira’

This study aimed to determine the late-season presence of weeds in reddish brown cotton (cultivar BRS Safira) and the critical times for removing weeds. The experiment was carried out in the area of Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) in Missao Velha-CE, Brazil, located at 7 degrees 42'07" S latitude and 39 degrees 24'18" WGr. longitude, during the 2007/2008 season. The treatments consisted of two control groups: weed-free crop during the initial period after crop emergency, and crop kept with weeds during initial period after plant emergency. Both consisted, 0; 20; 40; 60; 80 e 120 days after crop emergency (DAE), the weed community was evaluated by two phytosociological indices (relative dominance and relative importance). Regression analysis was performed as the model of sigmoidal Boltzman, using data from productivity separately within each type of competition, to identify the critical periods of competition, considering 2; 5 and 10% reduction in yield. The community of weeds was composed by 21 species, standing out among them: Richardia grandiflora, Amaranthus deflexus, Eleusine indica, Merremia aegyptia, Eragrotis pilosa, Cenchrus echinatus and Waltheria indica. Considering 2; 5 and 10% reduction in yield fiber as acceptable, the critical period before weed interference were, respectively, 8; 14 and 20 DAE. The critical period of weed interference, for those same levels of losses, were respectively, 100; 82 and 60 days.

Controle químico de biótipos de buva (Conyza canadensis e Conyza bonariensis) resistentes ao glyphosate

Studies were conducted at Estacao Experimental de Citricultura de Bebedouro, SP to evaluate the response of glyphosate-resistant horseweed and hairy fleabane biotypes to herbicides glyphosate, bromacil + diuron, diuron e paraquat isolated and in mixture and effect of a sequential application of glyphosate. The experimental design was of complete randomized blocks with four replication and seven treatments. The herbicides were applied with costal sprayer, constant pressure with three nozzles TT110015, the equivalent spray volume was 150 L ha(-1). The control was visually evaluated, trough percentile note scale. The best results were obtained to general control of weed with diuron isolated and glyphosate in mixture with bromacil + diuron while to glyphosate-resistant horseweed and hairy fleabane there was no difference between the treatments. After sequential application to Conyza sp control, the best treatment was obtained associated with diuron and bromacil+diuron.

Space dependency of chemical attributes in an area with sugarcane plantation in Pereira Barreto, SP

The behavior of the chemical attributes is directly influenced by superficial flow and water movement inside the soil. This work aimed to study the space dependency of chemical attributes in an area with sugarcane plantation in Pereira Barreto, SP. An area of 530.67 hectares was mapped using an equipment of Global Positioning System and obtaining a Digital Elevation Model. A set of 134 soil samples were collected every seven hectares in the depths of 0-0.25 m and 0.80-1.00 m. The pH, organic matter (OM), Ca, Mg, K, BS, CEC and base saturation (BS) were analyzed. All the chemical attributes presented similar behavior in the superficial and subsuperficial layer of the soil, which provided better visualization and definition of the homogeneous tillage zones.

Soil texture spatial variability of different parent material in pereira barreto, São Paulo state

The variation of soil textural characteristics is a function of the relief and parent materials. The objective of this work was to study soil texture spatial variability from different parent material in Pereira Barreto, SP. An area of 530.67 hectares was mapped through the use of Global Positioning System receivers and obtaining of Digital Elevation Models. A set of 201 soil samples was collected from every seven hectares, at three depths: 0 - 0.25 m; 0.25 - 0.50 m; and 0.80 - 1.00 m. The amounts of sand, silt and clay were obtained by the pipette method and analyzed by both descriptive statistics and geostatistics. Soil textures varied as a function of parent materials and topography.

Resistência de genótipos de tomateiro ao ácaro rajado

Avaliou-se a resistência de genótipos de tomateiro selvagens [Lycopersicon pennellii (LA 716), L. hirsutum var. glabratum (PI 126449, PI 134417), L. hirsutum (PI 127826, PI 127827), L. peruvianum (CGO 6707), L. peruvianum var. dentatum (WYR 2020, LA 111), L. peruvianum var. glandulosum (LA 1113-1, LA 1113-2)] e comerciais [(L. esculentum) Gem Pride, Santa Clara, e híbridos Bruna VFN, Carmem, Fortaleza, Débora Plus VFN] ao ácaro rajado (Tetranychus urticae).

Os genótipos LA 716, PI 126449, PI 134417, PI 127827, PI 127826 e Gem Pride apresentaram não-preferência para oviposição do ácaro rajado, sendo deterrentes quanto à classificação do IPO, enquanto os genótipos LA 111, WYR 2020, LA 1113-2 e LA1113-1 foram os mais preferidos para a oviposição e foram considerados como estimulantes pelo IPO.

Atributos físicos de um Latossolo Vermelho submetido a diferentes usos

The cultivation of the soil causes changes in physical attributes, depending on the intensity of preparation and management. The objective of this work was to evaluate the degree of modification of some physical properties of soil mid the S index, comparing areas of Pasture of grass Tanzania (Panicum maximum) and native forest with an area under maize (Zea mays L.) irrigated bay, a central pivot. The study was conducted in three areas within the Agency of Technology Agribusiness Paulista (APTA) Regional High Mogiana, located in Colina, SP. The experimental design was split plot in a factorial 3 x 3, with 4 replications, where the plots were installed in areas of Cultivation of corn, pasture and forest in the depths 0-0.1 m, 0.1-0.2 m 0.2-0.3 m. The physical attributes of soil were: resistance to penetration (RP), bulk density (Ds), microporosity (Micro), macroporosity (Macro), total volume of pores (VTP) and water retention in soil. The native forest had the best physical condition of soil in all parameters examined. The use of land and pasture with corn altered the physical structure of it, evidenced by the increase in penetration resistance and soil density and, reduction in macroporosity. The level of degradation of the managed soil was considered low, index S (<0035). The replacement of pasture by the corn crop in the soil tillage system provided a conventional mild improvement in soil physical characteristics.

Fertilização nitrogenada, densidade de plantas e rendimento de milho cultivado no sistema plantio direto

In maize (Zea mays L.), the inadequate nitrogen supply and planting density are considered limiting factors to the grain yield. The objective of this study was to evaluate the influence of different nitrogen levels and plant densities to the maize yield components and productivity. The experiment was carried out in the Cerrado region, located in the southern of the Maranhao State, Brazil, in a clay Oxisol (Ustox), cropped under the no-tillage system for six years. The randomized completed blocks experimental design with four replications was used, with treatments arrangement in a 5 x 4 factorial. The treatments were a combination of five doses of nitrogen as urea (0, 50, 100, 150 and 200 kg ha(-1)) and four plant densities (25,000; 50,000; 75,000 and 100,000 plants he). The grain number and mass per spike and grain mass per plant were improved by increased N and decreased plant density. Higher incomes of grains were obtained with adding concomitantly in N doses and in plants density. The maximum grain yield (11,9 Mg ha(-1)) was obtained with 120 kg ha(-1) of N and 83,000 plants ha(-1).
