1. Sampling Design of Soil Physical Properties in a Conilon Coffee Field
ABSTRACT Establishing the number of samples required to determine values of soil physical properties ultimately results in optimization of labor and allows better representation of such attributes. The objective of this study was to analyze the spatial variability of soil physical properties in a Conilon coffee field and propose a soil sampling method better

2. Novel Image Classification technique using Particle Filter Framework optimised by Multikernel Sparse Representation
ABSTRACT The robustness and speed of image classification is still a challenging task in satellite image processing. This paper introduces a novel image classification technique that uses the particle filter framework (PFF)-based optimisation technique for satellite image classification. The framework uses a template-matching algorithm, comprising fast march

3. Metamorfose planar via métodos Level Set e Particle Level Set para a reconstrução de superfícies tridimensionais
Inicialmente centralizadas na solução de problemas em Dinâmica dos Fluidos, as fronteiras dinâmicas, com o advento da modelagem mais robusta provida pelo método Level Set, expandiram os limites originais de sua aplicabilidade. Especificamente à área de Modelagem Geométrica, os trabalhos até então apresentados, relacionando o Level Set à reconstru�

4. Effect of chick weight, geometric mean diameter and sodium level in prestarter diets (1 to 7 days) on broiler performance up to 21 days of age
Seven hundred and twenty Ross 308 chicks were raised in a controlled environment room, distributed in a factorial design with 3 hatching chick weights (37, 40 and 44 g), 3 geometric mean diameter (GMD) (0.561; 0.783 and 0.997 mm) and 4 total sodium levels (Na) (0.12; 0.24; 0.36 and 0.48%) in the pre-starter diet (1 to 7 days). From 8 to 21 days (d) one singl

5. Reconhecimento de objetos em imagens digitais utilizando otimizaÃÃo por enxame de partÃculas / Object recognition in digital images using particle swarm optimization
The automatic recognition of objects aims to extract the visual information by computional devices. One way of addressing the problem of object recognition is through the technique of Template Matching viewed as a problem of global optimization. The objective is to determine the position of an object in an image, its rotation angle and the scale factor used.

6. Carreador lipÃdico nanoestruturado à base de cera de carnaÃba: desenvolvimento, caracterizaÃÃo e uso na encapsulaÃÃo de benzofenona-3
Solid lipid nanoparticles made of pure lipids (SLN) or a mixture of solid and liquid lipids (NLC) have been proposed as a category of carriers for cosmetic ingredients of current and growing interest due to a number of advantages compared to conventional formulations. Natural waxes are considered lipid matrices of great potential for the production of topica

7. Effect of chick weight, geometric mean diameter and sodium level in prestarter diets (1 to 7 days) on broiler perfomance up to 21 days of age
Seven hundred and twenty Ross 308 chicks were raised in a controlled environment room, distributed in a factorial design with 3 hatching chick weights (37, 40 and 44 g), 3 geometric mean diameter (GMD) (0.561; 0.783 and 0.997 mm) and 4 total sodium levels (Na) (0.12; 0.24; 0.36 and 0.48%) in the pre-starter diet (1 to 7 days).

8. Minimal set of ribosomal components for reconstitution of the peptidyltransferase activity.
A new approach is described to gain further information concerning the ribosomal components involved in the peptidyltransferase (PTF) activity exerted by Escherichia coli 50S subunits. A particle is reconstituted from highly purified proteins and RNA under modified incubation conditions. This particle contains only 16 out of the 34 distinct components consti

9. High-level expression of adeno-associated virus (AAV) Rep78 or Rep68 protein is sufficient for infectious-particle formation by a rep-negative AAV mutant.
Adeno-associated virus (AAV) codes for four closely related nonstructural proteins (Rep) required for AAV DNA replication and gene regulation. In vitro studies have revealed that either Rep78 or Rep68 alone is sufficient for AAV DNA replication. Rep52 and Rep40 are not required for DNA replication but have been reported to enhance the efficiency of accumulat

10. A cellular function is required for pseudorabies virus envelope glycoprotein processing and virus egress.
The mouse L-cell mutant gro29 is defective for egress of herpes simplex virus type 1 (HSV-1) virions and is significantly reduced in HSV-1 glycoprotein export (B. W. Banfield and F. Tufaro, J. Virol. 64:5716-5729, 1990). In this report, we demonstrate that pseudorabies virus (PRV), a distantly related alphaherpesvirus, shows a distinctive set of defects afte

11. Alveolar macrophage priming by intravenous administration of chitin particles, polymers of N-acetyl-D-glucosamine, in mice.
Intravenous (i.v.) administration of phagocytosable chitin particles (1 to 10 microm) in C57BL/6 mice and SCID mice primed alveolar macrophages (Mphi) within 3 days to yield up to a 50-fold increase in their oxidative burst when elicited in vitro with phorbol myristate acetate (PMA). C57BL/6 mice pretreated with monoclonal antibodies (MAbs) against mouse gam

12. The spliceosomal snRNP core complex of Trypanosoma brucei: Cloning and functional analysis reveals seven Sm protein constituents
Each of the trypanosome small nuclear ribonucleoproteins (snRNPs) U2, U4/U6, and U5, as well as the spliced leader (SL) RNP, contains a core of common proteins, which we have previously identified. This core is unusual because it is not recognized by anti-Sm Abs and it associates with an Sm-related sequence in the trypanosome small nuclear RNAs (snRNAs). Usi
