Microbial treatment of the powdered waste tire was studied to recycle the waste tires. Chemoautotrophic, acidophilic, iron-oxidizing bacterium was employed to unvulcanize the powdered tires. Biotreated rubber powder was compared to a untreated and a chemically treated powder. The results showed sulfur content of rubber powder (1.33%) were decreased to 1.22 by chemical treatment and 1.12% by microbial treatment for 20 days, 0.88%, for 30 days. One of the problems of the powdered utilization of the waste tires is that rubber powder leads to decrease mechanical properties when it is compounded with other virgin polymers. When the biotreated powder was compounded with natural rubber, the mechanical properties were less decreased when untreated or chemically treated powder. Therefore, the microbial treatment can be one of useful methods to recycle the waste tire.

This paper aims to look into internal/external representation of conflicts in Yeats’s political poems. To trace the nature of such conflicts, I look briefly at the rise of cultural nationalism to trace the nature of such conflicts. This cultural revival foregrounds the issue of conflicts between Yeats and audience, which creates tension that culminates in the Easter Rising, and result in the birth of terrible beauty. In this context, I would argue that what constitutes the “political” in Yeats's poems are Yeats's conflicts with himself. In this backdrop, I look at the conflicts in the poems “Easter, 1916”, “Sixteen Dead Men”, “The Rose Tree” and “On a Political Prisoner” through the central oxymoron “terrible beauty. In “Easter, 1916”, I would talk about how the sacrifice of the nationalists gives birth to terrible beauty, which is a fusion of representations of Ireland as beautiful young maiden and old ugly woman. In “On a Political Prisoner” as I would discuss how terrible beauty is embodied in a woman by juxtaposing an image of beautiful and young Constance Markiewicz in the distant past and in more recent past and present, when she turned ugly by her involvement in political activities and imprisoned as a result. I conclude by pointing to the ambivalence of conflicts as something which poses a threat and yet inspires Yeats's poetry.
Nancy Rawles`s My Jim: Reclaiming African American Herstory from Mark Twain`s Legacy
( Joe Won Yoon ) 한국영미문학페미니즘학회 2008 영미문학페미니즘 Vol.16 No.2
In the wake of Jean Rhys`s Wide Sargasso Sea, which brilliantly exposed the colonial unconscious that had been locked up in Charlotte Bronte`s Jane Eyre, a number of literary works have retold the famous stories of literary classics. Most of these novels recount the original stories from a different perspective and foreground some parts of the story that were either untold or suppressed in the famous, canonized works, thereby critically pointing out what is left out or marginalized. Nancy Rawles`s recent fiction My Jim (2006) is one such re-writing. Though inspired and motivated by Mark Twain`s Adventures of Huckleberry Finn (1885), it shifts the focus from Huck to Jim the runaway slave and artfully unfolds the story that Twain did not tell. Rawles`s My Jim is an attempt to extricate African American subjectivity from the network of material proprietorship and bodily exchange, and to re-position African American subjects in another set of human relations that are fundamentally different from what made slavery possible in the first place. The narrator Sadie`s continuous act of claiming Jim as hers is a desperate attempt to negate his status as Miss Watson`s property. By resituating Jim and herself in a binding relationship based on mutual recognition of each other`s worth that cannot be translated into mere price, Sadie creates an affective space wherein they can transcend the dehumanizing forces of slavery. The novel is Rawles`s attempt to reclaim the entire history of African Americans from the canonized white author`s imagination and recount it in a new narrative of the African American heritage. Through a successful negotiation between Mark Twain`s legacy and her own critical imagination, Rawles turns a white male author`s history of a slave into an African American author`s herstory of her people.

Oxidation of isophorone by various fungi was examined. Aspergillus niger oxidized isophorone to 4-hydroxyisophorone, 3-hydroxymethyl-5,5-dimethyl-2-cyclohexen-1-one and 5-hydroxymethyl-3,5-dimethyl-2-cyclohexen-1-one. 4-Oxoisophorone obtained by chromic acid oxidation of 4-hydroxyisophorone was transformed to 2,3,5-trimethyl-p-benzoquinone by acid treatment.
