Analyzing W.B. Yeats Selected Poetry Through Feminist Epistemology: A Reassessment

W.B. Yeats stands out as one of the most influential poets of the twentieth century. His symbolic poetry and his political and philosophical ideas are all prominently reflected in his work. During his lifetime, he was deeply influenced by a few remarkable women who made significant contributions to his poetic development and played a pivotal role in shaping his personality. Yeats's poems chosen for this study offer a profound insight into the predicament of women within various socio-cultural and economic contexts. This analysis will explore how Yeats projected female voices through multiple images and symbols in poems such as 'A Prayer for My Daughter,' 'Among School Children,' and 'Leda and the Swan.' While Maud Gonne is widely recognized as a central figure in Yeats's love poems, it's essential to acknowledge that she wasn't the sole woman who influenced the artist's evolution. Others, like Lady Gregory, Olivia Shakespeare, and George Hyde-Lees, the wife of W.B. Yeats, played significant roles in the later phase of his life, particularly in developing his philosophical treatise, "A Vision." In his final poems, Yeats attempted to convey his ultimate understanding of love, emphasizing its perfection in the unbroken relationship between the body and the mind. Works like 'Among School Children,' 'Leda and the Swan,' 'The Second Coming,' 'Sailing to Byzantium,' 'A Man Young and Old,' and many other universally acclaimed poems were inspired by his complex relationships with Maud Gonne and others

Evaluation of the Zone of Influence and Entrainment Impacts for an Intake Using a 3-Dimensional Hydrodynamic and Transport Model

Ballast water systems in large LNG carriers are essential for proper operations and stability. Water withdrawn from the surrounding environment to supply to the ballast can pose entrainment and impingement risk to the resident fish population. Quantification of these risks and the net effect on population is usually quite challenging and complex. Various methods over the last several decades have been developed and are available in the literature for quantification of entrainment of mobile and immobile lifestages of resident fish. In this study, a detailed 3-dimensional model was developed to estimate the entrainment of ichthyoplankton (fish eggs and larvae) and fish from an estuarine environment during the repeated short-term operation of a ballast water intake for an LNG carrier. It was also used to develop a zone of influence to determine the ability of mobile life stages to avoid impingement. The ichthyoplankton model is an Equivalent Adult Model (EAM) and assesses the number of breeding adults lost to the population. The EAM incorporates four different methods developed between 1978 and 2005. The study also considers the uncertainty in estimates for the lifestage data and, as such, performs sensitivity analyses to evaluate the confidence level achievable in such quantitative estimates for entrainment

Not AvailableUnder present investigation, AMMI (Additive main effects and multiplicative interaction) model was validated to study and identify the stable genotype in Volvariella volvacea (Paddy straw mushroom) under varied environmental conditions. A slight change in temperature and humidity can cause larger difference in the crop yield. Moreover, the identification of strain selection criteria for better yield is also needed to be identified for genetic improvement. The six strains of Volvariella volvacea (DMRO888, DMRO886, DMRO463, DMRO889, DMRO885 and DMRO484) were cultivated on cotton ginning mill waste substrate for the characterization of their agronomical traits. The correlation studies showed that yield was highly positively correlated with six traits namely total fruit body length (TFBL), Pileus diameter (PD), Gill width (GW), Stipe length (SL), Fruit body weight (FBW)and fruit body number (FBN) while it is negatively correlated with spawn run time (SRT). The DMRO463 was found most stable and average yielder is the all environment. Further the path correlation identified that PD and FBN traits are the best criteria for the selection of high yielding strain in screening experiments.Not Availabl

Retrospective Analysis to Quantify Migration of American Shad in an Impoundment on the Lower Susquehanna River

Proceedings of the 2013 Georgia Water Resources Conference, April 10-11, 2013, Athens, Georgia.We integrated several existing data sources (migration timing/behavioral, hydrological, variable power station operations, and a 3-D time-varying hydrothermal model) to quantify the migration of American shad, Alosa sapidissima, in Conowingo Pond, a 9,000 acre impoundment on the lower Susquehanna River relative to the potential individual and synergistic effects of thermal discharge from Peach Bottom Atomic Power Station (PBAPS) and Muddy Run Pumped Storage Station (MRPSS) operations. The two power stations are approximately 5 mi apart with PBAPS on the west western shore and MRPSS on the eastern shore. Our approach isolated factors contributing to the failure of a large proportion of American shad to reach upstream spawning areas. American shad has been targeted for restoration to the Susquehanna River. The PBAPS thermal plume shifts downstream, narrows in width upstream of discharge structure during MRPSS generation and moves upstream when MRPSS has been pumping for at least 12 hours (7 hours typical) primarily in summer at river flows = 12,500 cfs. Modeled maximum surface velocity of the upstream shifting plume is 5ft. Most of the Pond remains within the temperature and velocity tolerance range of migrating American shad allowing a wide passage zone. The maximum recorded MRPSS discharge velocity was < 6ft/s and restricted to a small area leaving substantial area of low velocity (< 2.0 ft/s) for migration passage. Almost the entire population (80-91%) of radio-tagged pre-spawned American shad successfully migrated past the two stations with minimal delay; the release location distance from MRPSS also did not influence travel speed. Estimated travel speed (4.0 to 6.7 mi/d) was similar to that reported by others. High natural river flows (= 55,000 cfs) with their attendant turbulence and turbidity and inefficiency of fishways pose significantly greater impedance to American shad upstream migration than the operation of either power station individually or synergistically.Sponsored by: Georgia Environmental Protection Division; U.S. Department of Agriculture, Natural Resources Conservation Service; Georgia Institute of Technology, Georgia Water Resources Institute; The University of Georgia, Water Resources Faculty.This book was published by Warnell School of Forestry and Natural Resources, The University of Georgia, Athens, Georgia 30602-2152.

Influence of Heat Treatment and Solid-State Fermentation on the Lignocellulosic Fractions of Substrates Supporting <i>Lentinula edodes</i> (Berk.) Pegler Cultivation: Implications for Commercial Production

Mushroom production in India has registered a considerable growth in the recent times. However, cultivation of shiitake mushroom, which represents a major share at a global level, is still at a primitive stage in the Indian subcontinent. The scarcity of raw materials and the cost of energy for substrate sterilization are the major hurdles for a large-scale production. The present study delves into the possibility of growing shiitake mushroom on lignocellulosic biomass (saw dust and wheat straw) processed with different heat treatments to develop a cost-effective production technology. Six different strains of shiitake mushroom, viz., DMRO-35, 51, 297, 388s, 410, 412, were used in this study. The substrates were exposed to a pasteurization temperature of 80 ± 5 °C in a bulk pasteurization chamber for three different times (H1–H3) and also to a high-pressure sterilization (H4) in an autoclave. DMRO-388s was found to be the most productive strain, irrespective of the substrate and heat treatment method used. Significant differences were observed in the biological yield depending on the type of substrate and heat treatment. Changes in the biochemical composition of the lignocellulosic residues in three different stages, viz., pre heat treatment, inoculation and primordial formation stages, were recorded. Changes in heat treatment levels and duration significantly altered the cellulose/lignin ratio of the growing substrate. High-pressure sterilization aided the rapid degradation of lignin in the substrate and increased its bioavailability, thereby facilitating the fungus achieving its potential yield. A significant correlation in the positive direction between the yield levels of the tested strains and the consumption of lignin in the growing substrate was found, suggesting the significance of pre heat treatment for the bioconversion of lignin and its subsequent utilization in the solid-state fermentation process. The substrate pre heat treatment under high-pressure sterilization was proved to be beneficial to obtain the maximum yields of shiitake mushroom
