    The World War II Patriotic Mother

    Get PDF
    The archetypal good mother and the archetypal patriotic mother are important symbols in American culture. Both are rooted in maternal work but are separated by two conflicting assumptions. The good mother nurtures her children and protects them from harm, while the patriotic wartime mother remains silent when the government sends her child directly into harm\u27s way. This study explores how the World War II press positioned mothers of soldiers to sacrifice their children in support of the nation\u27s war effort. The findings point to the importance of understanding the role of archetypes in news narratives

    Patriotic Motherhood and the Iraq War

    She plays a familiar character in our nation\u27s war stories and she has a warm place in our nation\u27s heart. She is the patriotic mother, a cultural symbol of bravery and sacrifice, stoicism and silence. Her image may reflect our historical understanding of the mothers of combat soldiers, but the story the national press tells about the mothers of U.S. soldiers in the Iraq War does not quite match these cultural expectations

    Effects of a giant impact on Uranus

    Get PDF
    The effects of a giant impact on Uranus with respect to the axis tilt of Uranus and its satellites are discussed. The simulations of possible giant impacts were carried out using Cray supercomputers. The technique used is called smooth particle hydrodynamics (SPH). In this technique, the material in the proto-Uranus planet and in the impactor is divided into a large number of particles which can overlap one another so that local averages over these particles determine density and pressure in the problem, and the particles themselves have their own temperatures and internal energies. During the course of the simulation, these particles move around under the influence of the forces acting on them: gravity and pressure gradients. The results of model simulations are presented

    Cisplatin ototoxicity blocks sensory regeneration in the avian inner ear

    Cisplatin is a chemotherapeutic agent that is widely-used in the treatment of solid tumors. Ototoxicity is a common side effect of cisplatin therapy, and often leads to permanent hearing loss. The sensory organs of the avian ear are able to regenerate hair cells after aminoglycoside ototoxicity. This regenerative response is mediated by supporting cells, which serve as precursors to replacement hair cells. Given the antimitotic properties of cisplatin, we examined whether the avian ear was also capable of regeneration after cisplatin ototoxicity. Using cell and organ cultures of the chick cochlea and utricle, we found that cisplatin treatment caused apoptosis of both auditory and vestibular hair cells. Hair cell death in the cochlea occurred in a unique pattern, progressing from the low frequency (distal) region toward the high frequency (proximal) region. We also found that cisplatin caused a dose-dependent reduction in the proliferation of cultured supporting cells as well as increased apoptosis in those cells. As a result, we observed no recovery of hair cells after ototoxic injury caused by cisplatin. Finally, we explored the potential for nonmitotic hair cell recovery via activation of Notch pathway signaling. Treatment with the γ-secretase inhibitor DAPT failed to promote the direct transdifferentiation of supporting cells into hair cells in cisplatin-treated utricles. Taken together, our data show that cisplatin treatment causes maintained changes to inner ear supporting cells and severely impairs the ability of the avian ear to regenerate either via proliferation or by direct transdifferentiation

    Modified Atmosphere Packaging (MAP) for Control of Black Spot Formation in Chilled Prawns

    Get PDF
    The marketing of organically labeled prawns is predominately in a cooked or raw frozen form to avoid the development of melanosis (black spot). Certification for organic status prohibits the use of any added chemicals. The application of 60% CO2/40%N2 modified atmosphere to chilled (raw) prawns using two species of prawn was investigated for the ability to control black spot formation. Sensory assessment and microbiological counts were used to determine the end of product shelf life. Modified atmosphere packaged (MAP) prawns exhibited no melanosis for up to 16 days. The high quality life was retained for 12 days; shelf life of 16 days, according to standard microbiological criteria, was achieved, which is more than twice previously reported for non-MAP prawns. Results suggest MAP may be an effective method for the marketing of organically grown prawns as well as those produced by conventional prawn aquaculture without application of the normal chemicals used to prevent black spot.

    Comparison of Power Dependence of Microwave Surface Resistance of Unpatterned and Patterned YBCO Thin Film

    Full text link
    The effect of the patterning process on the nonlinearity of the microwave surface resistance RSR_S of YBCO thin films is investigated. With the use of a sapphire dielectric resonator and a stripline resonator, the microwave RSR_S of YBCO thin films was measured before and after the patterning process, as a function of temperature and the rf peak magnetic field in the film. The microwave loss was also modeled, assuming a Jrf2J_{rf}^2 dependence of ZS(Jrf)Z_S(J_{rf}) on current density JrfJ_{rf}. Experimental and modeled results show that the patterning has no observable effect on the microwave residual RSR_S or on the power dependence of RSR_S.Comment: Submitted to IEEE Trans. MT
