AIMS To determine the prevalence of petechial spots in well babies. METHODS A total of 116 babies under the age of 12 months were fully examined at child health surveillance clinics. The number and site of petechiae were recorded together with details of possible causes. RESULTS A total of 27.6% of babies had one or more petechiae, 8.6% had two or more petechiae, and 2.6% had more than two....

to better understand seed dormancy breaking of bread wheat (triticum aestivum l.rl4137), we examined protein synthesis in dormant and after-ripened seeds.we used six treatments including dormant seed, dormant seed that were subjected to gibberllic acid (ga3) for 10 hours, dormant seed with one, three and six weeks of after-ripening and finally six weeks after-ripened seed subjected to abscisc a...

INTRODUCTION Microarray experiments often have complex designs that include sample pooling, biological and technical replication, sample pairing and dye-swapping. This article demonstrates how statistical modelling can illuminate issues in the design and analysis of microarray experiments, and this information can then be used to plan effective studies. METHODS A very detailed statistical mod...

A method of combining optical skin images obtained at different illumination angles is proposed to reduce the effect of specular reflection in normal white light clinical skin images in order to avoid optical interference with the analysis of skin line pattern. A weighted average image with weights determined by independent component analysis of the images shows a demonstrable reduction in the ...

OBJECTIVE The purpose of this clinical study was to evaluate the effectiveness of an intense pulsed light (IPL) irradiator system for the treatment of benign pigmented lesions. MATERIALS AND METHODS A total of 18 patients with lentigo solaris and eight patients with melanocytic nevi were treated once with an IPL system. After 2 months, the effect was evaluated on close-up photographs. RESUL...

The migration of UMTS carrier frequencies to the 2 GHz band has stimulated interest in radio coverage in urban environments. This paper examines the problem of poor signal quality close to buildings. It uses simulation based on approximate propagation models in a “generic” urban environment to estimate the relationship between size of coverage black spots and distance from the serving BS. Consi...

BACKGROUND Planning and transport agencies play a vital role in influencing the design of townscapes, travel modes and travel behaviors, which in turn impact on the walkability of neighbourhoods and residents' physical activity opportunities. Optimising neighbourhood walkability is desirable in built environments, however, the population health benefits of walkability may be offset by increased...

The replication and differentiation of spots in reaction diffusion equations are studied by extending the Gray-Scott model with self-replicating spots to include many degrees of freedom needed to model systems with many chemicals. By examining many possible reaction networks, the behavior of this model is categorized into three types: replication of homogeneous fixed spots, replication of oscil...

Replication and differentiation of spots in a class of reaction–diffusion equations are studied by extending the Gray–Scott model with self-replicating spots so that it includes many chemical species. By examining many possible reaction networks, the behavior of this model is categorized into three types: replication of homogeneous fixed spots, replication of oscillatory spots, and differentiat...
