    Ireland faces several targets for renewable energy usage, across the heating, transport and electricity sectors. These targets are set as a proportion of total energy usage. In the case of electricity, 40% of electricity must be generated from renewable sources by 2020. To meet this target, renewable electricity generation is subsidised through the Public Service Obligation levy, which appears on all consumers’ bills. The PSO is levied on residential consumers, commercial consumers and large industrial consumers according to their contribution to peak demand – the more the sector contributes to peak demand, the higher the portion of PSO that they pay

    Complex permeability of soft magnetic ferrite polyester resin composites at frequencies above 1 MHz

    Composite soft magnetic materials consist of magnetic particles in a non-magnetic matrix. The properties of such materials can be modelled using effective medium theory. Measurements have been made of the complex permeability of composites produced using ferrite powder and polyester resin. The success of various effective medium expressions in predicting the variation of complex permeability with composition has been assessed

    Slicing the Pie: Classes and the Distributive Effects of Post-WWII U.S.Governmental Fiscal Policies

    Get PDF
    Time series analysis of the relative class income distributional consequences of postwar U.S. fiscal practices reveals that governmental revenue policies have had a procapital bias while state expenditures have tended to favor labor. The net impact of these processes has served to leave the marketgenerated income distribution largely intact, despite the historically unprecedented growth of the public sector during this period. Finally, in light of these findings, the distributive impact of the current administration\u27s fiscal program are considered

    The Lived Experience of Counselor Education Doctoral Students in the Cohort Model at Duquesne University

    This was a phenomenologically-oriented inquiry of the lived experiences of counselor education doctoral students in a cohort model. This inquiry sought to explore, describe, and understand students\u27 everyday lived experiences in a cohort model in the Executive Doctoral Program in Counselor Education and Supervision (ExCES) at Duquesne University, where the doctoral program is structured as a three-year, full-time, closed cohort model. The existential framework proposed by van Manen (1990) provided a framework for describing and understanding students\u27 lived experiences in the corporeal, temporal, spatial, and relational realms of experience. The strategies used for this inquiry were based on multiple informants and data sources, which included individual and dyad interviews, and focus group discussions. A semi-structured protocol was used to gather phenomenological data from a purposive sample of twenty-six informants, who were affiliated with seven different cohort groups in the ExCES program. At the time of data collection, seven individuals were involved in an active cohort experience, nine individuals had completed the cohort experience and were working on their dissertations, and ten individuals had graduated from the program. Colaizzi\u27s (1978) descriptive method of analysis was used to illuminate the common themes within the informants\u27 perceptions and experiences in the program. The analysis generated themes that describe the informants\u27 corporeal, temporal, spatial, and relational lived experiences in a cohort model. The analysis yielded potential hypotheses and directions for future research, and implications and recommendations for practice. The findings have provided an initial description of students\u27 everyday lived experiences in a cohort model, and insight into the contextual influences that bear on these experiences, which will guide educators in their current roles

    The objective of this investigation was to analyze the chemical and functional properties of a flour made from the defatted meal of pumpkin seeds from the cultivar Lady Godiva (Cucurbita pepo L.) in order that its potential as a novel food source might be evaluated. The proximate composition of two crop years (1978 and 1979) was determined. Defatted flour of pumpkin seed 1978 and 1979 had 8.91 and 4.56 percent moisture, 62.21 and 61.90 percent crude protein, 8.97 and 9.23 percent ash, 8.41 and 4.53 percent total lipid, 3.57 and 3.96 percent crude fiber, and 7.93 and 15.82 percent nitrogen-free extract. The mineral content (K, Ca, Mg, Na, Fe, and Zn) of the two flours was determined by atomic absorption spectrophotometry. Calcium, iron, and potassium (279, 16, and 1500 mg/100g, respectively) in the pumpkin seed meals were found at levels comparable to the levels found in the soy reference. The levels of magnesium, sodium, and zinc (540.9, 144.9, and 22.9 mg/100g, respectively) in the pumpkin seed meal were found in much greater levels than in the soy concentrate (269, 6, and 6.5, respectively). Nitrogen solubility profiles of the defatted pumpkin seed meals showed pumpkin 78 acquiring its isoelectric point at pH 3 and its maximum solubility at pH 10. Pumpkin 79 also acquired its isoelectric point at pH 3 and its maximum solubility was at pH 10. Water holding capacity revealed pumpkin 79 capable of holding 4.85 grams water/gram flour, which was not significantly different (0.05 level) from the 4.47 grams water/gram flour that a soy concentrate (used as a reference in this study) was capable of holding. The whippability value for pumpkin 79 (194.30 percent volume increase) was significantly different (0.01 level) from soy concentrate (118.66 percent volume increase). Thefoamproducedbyeachofthe flours was very stable. Pumpkin 78 was found to be significantly lower than pumpkin 79 in water holding capacity and whippability. This difference was thought to be due to the longer storage time of pumpkin 78 and the initially higher lipid content pumpkin 78. Thus it was not included in the comparison between pumpkin seed meal and soy concentrate on water holding capacity and whippability. The mean value of oil holding capacity for pumpkin 78 and 79 was 4.26 grams oil/gram flour, and oil holding capacity for the concentrate was 3.05 grams oil/gram flour. The value for the pumpkin flour was significantly greater than the soy concentrate at the 0.01 level. The results of emulsifying capacity (EC) showed pumpkin 78 and 79 were able to emulsify approximately the same amount of oil (67.14 ml oil/g flour and 67.85 ml oil/g flour, respectively). The soy concentrate was found to emulsify a significantly smaller amount of safflower oil than pumpkin 78 or 79. The EC for soy was 32.94 ml oil/g flour. Heat stability of water extracts of both pumpkin seed meal and soy concentrate proved to be very stable even after one hour in boiling water. It is felt that the functional property of heat stability deserves further scrutiny
