Three studies were conducted. In the first study, 12 Yorkshire barrows (initial BW of 23.2 ± 2.0 kg) were allotted to 2 dietary treatments with 6 replications per treatment using a completely randomized design to determine apparent Ca and P digestibility (AD), true digestibility (TD) and endogenous output (EO) in a corn/SBM-based diet. All pigs were placed in individual feeder pens that allowed for easy collection of individual feces. The AD of Ca and P were 28.4% and 23.9%, respectively. Their TD of 42% and 40% for Ca and P respectively were significantly (P < 0.05) higher than the corresponding AD. EO was 0.8g for Ca and 1.3g for P per kg of dry matter intake (DMI). In the second study, the optimal dietary ratio of true digestible Ca and P was determined in terms of its effect on growing pig performance, excretion of Ca and P in feces and urine in a corn/SBM-based diet using a randomized complete block design. Thirty six growing barrows (initial BW: 24.2 ± 1.9 kg) were allotted to 6 dietary treatments with 6 replications per block. Six corn/SBM-based diets with very similar nutrient contents were formulated but differed in their dietary ratio of Ca to P. The balances of Ca and P and their true digestibility/retention were calculated for each diet. Animal performance and true retention of both Ca and P was optimal (P < 0.05) with diet 2 with a true digestible Ca to P ratio of 0.82: 1 compared to other experimental diets. The third study was conducted with a similar protocol to that used in experiment 1 involving 12 barrows (initial BW: 23.9 ± 1.1 kg) to determine Mg, Cu, Fe, Mn, Se and Zn TD values for the growing pig. Se and Zn AD of 73.9% and 9.5% significantly (P < 0.05) underestimated their TD of 82.1% and 15%, respectively. Se and Zn EO were 0.00004mg and 0.01 mg/kg of DMI, respectively. The TD and EO for Mg, Cu, Fe and Mn could not be estimated because of their negative AD.

The Bahamian Archipelago is one of the few locations in the world where ooid formation is actively occurring. Ooid cortices from six locations in the region were incrementally dissolved and analyzed for 14C, δ18O, δ13C, Mg/Ca and Sr/Ca ratios. Ooids were examined under SEM after each step in the incremental analyses to characterize the nature of dissolution. Radiocarbon dating indicates that surface ooids began forming across the Archipelago between 1000 and 2800 yr BP and continue to form today. The ooids have the same pattern of microboring alteration across the region. The surface and outer cortex of the ooids are punctuated with unfilled microborings, whereas the inner cortex contains two morphologies of aragonite cement filling the microborings. The two morphologies of cement form in association with two different species of cyanobacteria, one is Solentia sp. the other is interpreted to be Hyella sp.. The chemistry of ooids from across the region is remarkably similar. δ18O and δ13C values for all samples vary directly, having a slope of approximately 1. The outer cortex has low δ18O and δ13C values of -3.4‰ and 0.2‰ respectively, whereas the δ18O and δ13C values of the inner cortex are high with values of 1.9‰ and 6.8‰ respectively. The presence of aragonite cement in microborings in the inner cortex increases the overall isotopic composition of both oxygen and carbon in the ooid, causing it to appear close to equilibrium with seawater. The isotopic variation in δ18O and δ13C within the cortex can be characterized as a mixing line between the low values in the unaltered ooid laminae and the aragonite cement in the microborings. The most exterior portion of the ooid has very high Mg/Ca values and is interpreted as an amorphous calcium carbonate (ACC) coating. There are two other phases in the cortex, both being aragonite. The outer cortex has a higher Mg/Ca ratio and lower Sr/Ca ratio than the inner cortex. This difference in chemistry is a result of the presence of aragonite cement in the inner cortex. Stable isotopic and trace element results coupled with SEM investigations indicate that microbes do not play a role in ooid formation, but instead alter the texture and chemistry of ooids after they have formed. This alteration occurs throughout the entire shoal region. A new model of ooid formation is proposed whereby a veneer of ACC precipitates on an ooid while it is at the sediment-water interface (the active phase). This veneer of ACC later recrystallizes to aragonite needles, possibly nucleating on organic material and a new cortex layer is formed. Observations from this study lead to a deeper understanding of the chemical processes involved in ooid genesis, which allows for a better understanding of paleoenvironments hosting ooid formation. / Thesis (Master, Geological Sciences & Geological Engineering) -- Queen's University, 2009-01-27 13:29:42.765

Bahiṇa Bai was a female poet-Saint whose participation in the Maharashtrian devotional movement known as the Varkari Panth transformed the image of female devotionalism in the region. A collection of her poetic writings, the Samta Bahiṇabaica Gatha, demonstrates her struggle to reconcile the demands of domesticity with those of devotionalism. Bahiṇa Bai simultaneously extols the roles of the pativrata, devoted wife, and the bhakta, the devotee, in her lyrical compositions, and resolves the tensions between domesticity and devotion by merging her husband's identity with that of Viṭhoba, a localized force of Viṣṇu. This thesis argues that Bahiṇa Bai's rebellion against a parochial vision of female spirituality integrates elements of Brahmanic orthodoxy, non-dual philosophy and bhakti practice.

Antonio Averlino, known as Filarete (1400--1469), wrote that architecture is a gestational process, likening the architect to the mother and the father as the client. The process requires the architect-mother to " fantasticare e pensare e rivoltarselo per la memoria," fermenting ideas and incubating them in conjunction with one's memory. The intent is to understand mnemonics as a creative operation in Filarete's Trattato di Architettura. A key to this lies with Filarete's personal symbol, the bee. The bee's process of mellification acts as a metaphor of the architect's gestational design. The bee, long utilized as a memorative trope, points towards other memory models created throughout the treatise, culminating with the design for the House of Vice and Virtue. Directing the reader and inhabitants of the city in a social narrative, Filarete's architecture reveals the dependence upon remembrance and virtue for the city's creation and public rituals to sustain its life.

O objetivo da modelagem é analisar o impacto desses equipamentos na operação em regime permanente de sistemas elétricos de potência. Três equipamentos são considerados: o STATCOM (Compensador Estático Síncrono), SSSC (Compensador Série Síncrono Estático) e o UPFC (Controlador Unificado de Fluxo de Potência). Feita a modelagem, os estudos têm início com uma busca do melhor ponto de inserção do equipamento no sistema. Esse ponto é obtido através de indicadores de sensibilidade fornecidos pelo programa de FPO implementado. Posteriormente, é feita uma comparação das Regiões de Segurança do sistema definidas com e sem o equipamento FACTS em operação. O aumento da Região de Segurança indica a melhoria geral das condições operativas, obtida pela inserção do equipamento. O algoritmo primal-dual de Pontos Interiores é usado na resolução do problema FPO. O desempenho do algoritmo é analisado com os equipamentos FACTS operando livremente e em suas capacidades máximas. São analisados resultados de simulações com diferentes sistemas teste.

Esta dissertação de mestrado descreve o estudo realizado sobre como a oferta de estrôncio afeta a razão Sr/Ca em hidroxiapatita formada in vitro. Este trabalho pretende dar subsídios para que posteriormente seja possível fazer um estudo da razão Sr/Ca em função da temperatura também em hidroxiapatita formada in vitro. Foram utilizadas células osteoblásticas da linhagem MG-63 com concentrações de estrôncio no meio de cultura que variaram de 0,0 até 33,0 microgramas por mL de meio. Os nódulos ósseos formados pelas células foram caracterizados pelas técnicas Absorção de Infravermelho por Transformada de Fourier (FT-IR), que foi utilizada com o objetivo de identificar ligações de fosfato nas amostras, e Difração de Raios-X (XRD), que teve como objetivo confirmar a presença de hidroxiapatita nos minerais formados e comparar a cristalinidade do material com e sem estrôncio. A quantificação da razão Sr/Ca foi feita utilizando as técnicas Retro-espalhamento Rutherford (RBS) e Emissão de Raios-X por Indução de Partículas (PIXE), que são capazes de fazer a identificação e quantificação elementar. Os resultados obtidos mostram que os nódulos formados são compostos por hidroxiapatita. Com relação à quantificação, mostrou-se que não foi possível substituir mais de 10% do íons de cálcio por íons de estrôncio, o que está de acordo com previsões teóricas. Além disso, para altas concentrações de estrôncio no meio a mineralização do cálcio diminuiu duas ordens de grandeza e as medidas da razão Sr/Ca obtiveram resultados bastante dispersos, indicando uma possível mudança metabólica das células que parece inviabilizar o bom funcionamento fisiológico das mesmas. / This Masters dissertation describes the study of how the availability of strontium affects Sr/Ca ratio of in vitro hydroxyapatite. This work intends to provide the basic understanding needed to a future study of how temperature changes Sr/Ca ratio in this material. MG-63 cells were grown in the culture medium doped with 0.0, 1.0, 2.0, 4.1, 8.2, 16.4, 22.9 and 33.0 micrograms of Sr/mL. The nodules formed by osteoblastic cells were characterized by Fourier Transform Infrared Spectroscopy (FT-IR) technique, used to identify phosphate domain, and X-Ray Diffraction (XRD) technique, which was used to verify the presence of crystallized hydroxyapatite in the mineral composition with and without strontium. Quantification of Sr/Ca ratio was made using the Rutherford Backscattering (RBS) and Particle Induced X-Ray Emission (PIXE) techniques, which are used to do elementary identification and quantification. The results of characterization confirmed the presence of hydroxyapatite in the cultivated MG-63 cells. The experiments have shown that it was not possible to replace more than 10% of the calcium ions by strontium, which is consistent with theoretical predictions. In addition, high concentrations of strontium in the growing solution, reduced the mineralization yield and also the Sr/Ca ratio, indicating a possible change in the metabolism of the cells.
