this study was aimed to determine abundance and body distribution of prm in laying hens of arak. a total of 1400 laying hens were randomly examined from january to june 2008. of those, 26 (92.86%) layer farms were found to be infested with dermanyssus gallinae (39.3%). there was significant association between prevalence and climatic conditions of the region. the most common predilection site o...

doi: 10.5694/mja15.00881 As my Aunty placed the possum skin cloak over me, I experienced a profound “inner experience” of cultural healing and connection. Wearing the cloak as part of the Wrapture project (http://www.speakingincolour.com.au/wrapture) restored an aspect of cultural traditional practice. It touched me holistically, creating a sense of healing, spiritual connection, belonging and ...

Within the range of validity of the stationary diffusion equation, an ideal diffusive-light invisibility cloak can make an arbitrary macroscopic object hidden inside of the cloak indistinguishable from the surroundings for all colors, polarizations, and directions of incident visible light. However, the diffusion equation for light is an approximation which becomes exact only in the limit of sm...

Metamaterial is not a well-defined terminology. In fact, this terminology does not mean any specific material, but instead a new way of thinking. Usually this term means carefully engineered material structures composed of carefully designed inclusions that can exhibit unusual electromagnetic properties not inherent in the individual constituent components [1]. These properties include, for exa...

We have proposed a scheme and presented the first experimental demonstration of acoustic illusion, by using anisotropic metamaterials to manipulate the acoustic field near boundaries of arbitrary curved geometry. Numerical simulations and experimental results show that in the presence of an illusion cloak, any object can be acoustically transformed into another object. The designed illusion clo...
