the forming of the zionism regime and its system in which one is imprisoned suppressed and tortured has motivated the poets to employ birds and other kinds of animals as codes and secret symbols as to express his own concealed meanings and implications. the nature of the animals as well as their characteristics provides the inspiration for the palestinian poet to create his/her works by utilizi...

The Secret Garden is an interactive narrative potential space, which aims to be a hidden rest area in urban space and a site to interrogate and reflect on the human experience. A digital image of the tree with its ‘will’ to grow stands in the space. A spectator’s secret will feed the tree. JeeHee’s The Secret Garden installation suggests a cross-art form. Sound, light and visualisation will des...

An efficient procedure has been developed for obtaining similarity measures for complex acoustic signals in small birds. Birds were trained using operant conditioning procedures to detect changes in the repeating background of an ongoing sound. Response latencies for detection were used to construct similarity matrices. Multidimensional scaling procedures were then used to produce spatial maps ...

Previous reports have suggested that green light enhances broiler growth at an early age, whereas blue light enhances growth at older ages. The aim of this study was to examine the effect of a switch in monochromatic light at 2 ages on growth and development of broilers. Male chicks (Anak, n = 640) were used. After hatch, chicks were weighed, wing-banded, and blocked into treatment groups. Chic...

ica (printed in stages during 1827–1838) by American ornithologist, naturalist, and painter John James Audubon (1785–1851), shows a pair of oft-vilified brown-headed cowbirds. This painting appears in the book as one of 435 life-sized watercolors that were reproduced from Audubon’s hand-engraved plates. In this painting, he portrays the birds frozen in act of foraging, a technique he honed from...

For bids, hearing is second in importance only to vision for monitoring the world around them. ./\vim hearing is most sensitive to sounds from about 1 to 4 kHz, although they can hear higher and lower frequencies. No species of bird has shown sensitivity to ultrasonic frequencies (>20 kHz). Sensitivity to frequencies below 20 Hz (dasound) has not received much attention; however, pigeons and a ...

It has been said that quantum cryptography in general o ers a secure solution to the problem of key enhancement This means that two parties who already share a small secret key can use quantum protocols to establish a new large secret key This large secret key can be arbitrarily long and is unbreakable Thus to date the main contribution of quantum cryptography has been believed to be quan tum k...

It has been said that quantum cryptography in general o ers a secure solution to the problem of key enhancement. This means that two parties who already share a small secret key, can use quantum protocols to establish a new large secret key. This large secret key can be arbitrarily long and is unbreakable. Thus, to date, the main contribution of quantum cryptography has been believed to be quan...

Visual and auditory reaction times (VRT and ART) were studied in 38 male and 41 female healthy medical students in the age group of 17-18 years. Subjects were presented with two visual stimuli viz red and green light stimuli and two auditory stimuli viz high pitch and low pitch sound stimuli. The R.T. to red light was significantly lower than to green light stimulus in both sexes. No statistica...

In this thesis, the physics of birds phonation is discussed using a two-mass models approach and the theory of nonlinear dynamics. Two-mass models of the human larynx (rescaled two-mass model and trapezoidal model) have been adapted to the dimension of the avian syrinx to study pressure onset, control of harmonic overtones and “registers” of the sound radiated by the birds vocal organ (syrinx) ...
