God for Catholicism : 캐도��의 신관
Thomas 이화여자대학교 기독교학회 1966 포도나무 Vol.- No.3
Thomas's는 다음과 같이 신의 존재를 증명한다. 신의 존재를 다음의 다섯가지 방법으로 증명할 수 있다고 답변한다. 첫번이고 가장 명백한 방법은 "운동(motion)"에 관한 토론이다. 무엇이 움직이고 있다는 것은 우리가 분명히 명백하게 느낄 수 없다. 움직이는 것은 모두 다른 사물에 의해 움직여 지고 있는 것이다. 왜냐하면 사물이 어떤 것을 향해 움직이고 있는 잠재력을 가지고 있기 전에는 움직일 수가 없기 때문이다. 즉 행동을 하고 있으므로 움직이는 것이다.
Incipient Cavitation in a Bulb Turbine: Model Test and CFD Calculation
Necker, Jorg,Aschenbrenner, Thomas Korean Society for Fluid machinery 2011 International journal of fluid machinery and syste Vol.4 No.1
For a certain operating point of a horizontal shaft bulb turbine (i.e. volume flow, net head, blade angle, guide vane angle) the efficiency for different pressure levels (i.e. different Thoma-coefficient ${\sigma}$) is calculated using a commercial Computational Fluid Dynamics (CFD-)-code including two-phase flow and a cavitation model. The results are compared with experimental results achieved at a closed loop test rig for model turbines. The comparison of the experimentally and numerically obtained efficiency and the visual impression of the cavitation show a good agreement. Especially the drop in efficiency is calculated with satisfying accuracy. This drop in efficiency in combination with the visual impression is of high practical importance since it contributes to determine the admissible cavitation in a bulb-turbine. It is seen that the incipient cavitation in Kaplan type turbines has no major importance in determing this admissible amount of cavitation.

An Economic Evaluation of the European Union’s 2030 Climate Policy Plan
Thomas R. Sadler(Thomas R. Sadler ) People&Global Business Association 2023 Global Business and Finance Review Vol.28 No.1
Purpose: The purpose of the study is to evaluate the European Union’s “Fit for 55” plan, announced in 2021, which intends to meet a 2030 goal of reducing carbon emissions by 55 percent from 1990 levels. Design/methodology/approach: An analytical model is used to assess the impact of the EU environmental policies, including the carbon border tax, emissions trading system, energy efficiency, and emission standards. Findings: The study finds that the environmental policies achieve different policy criteria, including cost minimization, equalization of marginal abatement cost, minimization of general equilibrium cost, political feasibility, and minimization of inequitable impacts across income groups. But no single policy instrument is necessarily superior to the others. The paper finds that a revenue-neutral carbon border tax and an emissions trading system with auctioned permits satisfy the most evaluation criteria. Research limitations/implications: For the purpose of simplification, the model ignores dynamic extensions. That is, the adjustments of businesses to policy measures and the effects on emissions are beyond the scope of this analysis. Originality/value: The study develops a model that evaluates the European Union’s environmental policies in a unifying perspective, assessing the tradeoffs of policy design.
Prospects for Canada’s Federalism in the 21st Century
Thomas R. Klassen(Thomas R. Klassen ) 한국캐나다학회 2007 Asia-Pacific Journal of Canadian Studies (APJCS) Vol.13 No.1
When Canada was created in 1867 it was a union of essentially equal provinces, with federal powers balanced between the House of Commons and the Senate. The new country was closely tied to Great Britain, and Aboriginal peoples were excluded from the governance of Canada. Developments in the past 140 years including the increase in the scope of provincial activities call for reforms to Canada’s governance structures especially with regard to: 1) the head of state; 2) the Senate; 3) the Atlantic provinces; 4) the role of Aboriginal peoples; and 5) education policy. Reforms in these areas, including a “made-in-Canada” head of state, a transformation of the Senate, a review of how the Atlantic provinces might better collaborate, the inclusion of Aboriginal peoples in governance fora, and a greater federal role in education policy will prepare Canada for the challenge and opportunities of the 21st century.

Filtration membrane technologies are used extensively in dairy processing and due to the high quantities of both organic and inorganic foulant, membrane fouling is a significant problem in the industry. To address this issue, a polyzwitterionic antifouling coating was applied to polyethersulfone ultrafiltration membranes for reduction of biofouling in skim milk filtration. The novel polyzwitterion was synthesised from a branched polyethyleneimine-based macroinitiator to allow multidentate binding to polydopamine coated membranes. Attachment of polyzwitterion to the polydopamine was confirmed using FTIR-ATR and XPS and the coating proved effective in increasing the wettability and smoothness of the membrane surface as well as reducing its charge. The reduced strength of binding between proteins and the membrane of the coated membrane compared to the control was demonstrated with its positive influence on fouling coefficient and recovery of the membranes while retaining skim milk flux and the rejection characteristics of the control membrane. The improved filtration characteristics of the coated membranes were generally retained through multiple cleaning cycles, though there was evidence of oxidative degradation after sanitation.
Is Africa's Recent Growth Sustainable?
Thomas Barnebeck Andersen,Peter Sandholt Jensen 한국국제경제학회 2014 International Economic Journal Vol.28 No.2
In this paper we argue that the answer, to the question of whether Africa's recent growth is sustainable, is yes. Our optimism rests on the finding that differences in the level of institutional quality predict cross-country variation in African economic growth during the period 1995–2011. This finding is quite robust. It holds in OLS, LAD and 2SLS settings; it holds for different measures of institutions and different measures of economic growth; and it holds for the period before and the period after the global financial crisis. We also show that changes in institutional quality predict cross-country variation in African economic growth. Moreover, if we split our sample into two equally sized groups, a high-growth and a low-growth group, then the high-growth group has experienced a statistically significant increase in institutional quality, whereas the low-growth group has not. Overall, this makes it probable that institutions have played an important part in Africa's recent growth acceleration. The continent has seen many false dawns, caused in large part by increases in commodity prices, but a growth acceleration driven by institutions is likely to signify a genuine African takeoff.
