Seed processing and dormancy break treatments are recommended for rendering seeds restoration-ready. Conversely, fruit structures seed coats may protect from environmental harm in the field. We evaluated effects of (by either keeping or extracting seeds) and/or scarification (of physically dormant on seedling emergence establishment 10 legume tree species tropical forests savannas Central Brazi...

The attachment glycoprotein (G) of respiratory syncytial virus (RSV) is synthesized as two mature forms: a membrane-anchored form and a smaller secreted form. Mutant cDNAs were constructed that encoded one or the other form of the protein and were expressed in recombinant vaccinia viruses (rVV). Mice were immunized with rVV by dermal scarification or i.p. injection to determine the contribution...

Introduction Diagnosing elemental mercury poisoning requires a high index of clinical suspicion with attention to thorough environmental, social, and family history. Due to its many nonspecific and slowly developing symptoms, the differential diagnosis is extensive and challenging. Diagnosis often requires costly laboratory and radiologic investigation to exclude other disease processes. Case R...

Tattoos, piercing, and scarification are now commonplace among adolescents and young adults. This first clinical report from the American Academy of Pediatrics on voluntary body modification will review the methods used to perform the modifications. Complications resulting from body modification methods, although not common, are discussed to provide the pediatrician with management information....

Angora, New Zealand, and Dutch-belted rabbits were tested for their susceptibility to graded doses of Herpesvirus hominis type 2 administered by vaginal instillation, intracorneal injection, and scarification of the cornea. Central nervous system involvement and death occurred after infection by the various routes employed. Prior immunization of Dutch-belted and New Zealand rabbits with viable ...

Inoculation of vesicular stomatitis New Jersey virus (VSNJV) by skin scarification of the coronary-band in cattle, a natural host of VSNJV, resulted in vesicular lesions and 6-8 log(10) TCID(50) increase in skin virus titers over a 72 h period. Virus infection was restricted to the lesion sites and lymph nodes draining those areas but no virus or viral RNA was found in the blood or in 20 other ...

In automatic surface inspection, one has to solve the problem of detecting small surface defects which locally break the homogeneity of a texture pattern. Textures are generally classified into two major types, structural and statistical [1]. Structural textures are those that are composed of repetitions of some basic texture primitive, such as directional lines, with a deterministic rule of di...

The Limited Receptive Area (LIRA) neural classifier is proposed for texture recognition of mechanically treated metal surfaces. It may be applied in systems that have to recognize position and orientation of complex work pieces during micromechanical device assembly as well as in surface quality inspection systems. The performance of the proposed classifier was tested on a specially created ima...

The context of this paper is the design of a kinesthetic interface to virtual environments. Several kinesthetic interfaces have previously been developed. Minsky[ 15lhas developed a device for creating “virtual sandpaper”. A powered joystick interfaced to a real-time computer simulation allows the user to “feel” textured surfaces. The simulation implements textures as a mapping from joystick po...
