On the threshold of forgetting: Amnesiac identities and the Brazilian capital

Centuries after Locke asserted the importance of memory to identity, Freudian psychology argued that what was forgotten was of equal importance as to what was remembered. The closing decades of the nineteenth century saw a rising interest in the nature of forgetting, resulting in a reassessment and newfound distrust of the long revered faculty of memory. The relationship between memory and identity was inverted, seeing forgetting also become a means for forging identity. This newfound distrust of memory manifested in the writings of Nietzsche who in 1874 called for society to learn to feel unhistorically and distance itself from the past - in what was essentially tantamount to a cultural forgetting. Following the Nietzschean call, the architecture of Modernism was also compelled by the need to 'overcome' the limits imposed by history. This paper examines notions of identity through the shifting boundaries of remembering and forgetting, with particular reference to the construction of Brazilian identity through the ‘repression’ of history and memory in the design of the Brazilian capital. Designed as a forward-looking modernist utopia, transcending the limits imposed by the country's colonial heritage, the design for Brasilia exploited the anti-historicist agenda of modernism to emancipate the country from cultural and political associations with the Portuguese Empire. This paper examines the relationship between place, memory and forgetting through a discussion of the design for Brasilia.

Relationships between crude protein and mineral concentrations in alfalfa and value of alfalfa silage as a mineral source for periparturient cows

One hundred and eight samples from three cultivars of alfalfa were obtained from three cuttings in 1996-1998 to evaluate the relationship between crude protein (CP) and mineral concentrations of alfalfa with cutting and maturation. The CP content drastically decreased from 27.9 to 11.4% on DM with maturity. Highly positive correlations were observed between CP and K in the first and the second cutting of alfalfa. The Ca content remained almost constant throughout the growth period. Four multiparous Holstein cows were assigned an alfalfa silage diet or an orchardgrass silage diet from 3 weeks prepartum to 1 week postpartum to examine the effect on the mineral balance. In the prepartum and postpartum diet, the roughage to concentrate ratio was 70:30 and 50:50, with alfalfa being 50 and 100% of the roughage, respectively. The alfalfa contained 1.93% of K. No metabolic disorders occurred, but the body weight decreased drastically from 1 to 6 days postpartum with each diet because of the high milk production immediately after the parturition. Positive retention of N, Ca, P, Mg, and K was observed prepartum, whereas the cows had negative N and mineral retention from 2 to 4 days postpartum. The Ca and P absorption, and Mg retention of cows with the alfalfa diet were higher than with the grass diet. The plasma Ca and inorganic P were not affected by diet, but the plasma PTH at parturition and plasma hydroxyproline from 1 week prepartum to 1 week postpartum were higher with the alfalfa diet. These results suggest that the low K alfalfa is suitable not only to prevent the incidence of milk fever but also to increase Ca, P and Mg utilization of periparturient cows, but the mineral supplementation is needed for the postpartum cows immediately after the parturition.

Ozothamnus diosmifolius (Vent.) DC flower and leaf essential oils

Essential oils of rice flower, Ozothamnus diosmifolius, were analyzed by capillary gas chromatograplay-mass spectrometry. Flower oil contained beta-pinene (28.4%) and 1,8-cineole (28.2%), while the leaf oil contained a-pinene (26.0%), beta-pinene (11.6%) and 1,8-cineole (22.2%). Both oils had small amounts of spathulenol (4.1% and 5.2%, respectively).
