Assays of cell and Nuclear Fusion
Methods in enzymology, 2002Co-Authors: Alison E. Gammie, Mark D. RoseAbstract:Publisher Summary This chapter discusses various assays of cell and Nuclear Fusion. The pathway of yeast mating forms a microcosm of the cell biological universe, encompassing fundamental problems in signaling, transcriptional regulation, polarization, motility, and membrane Fusion. Each step in the pathway has been defined and dissected by the isolation and analysis of numerous mutations that cause specific defects in the efficiency of mating. Certain profoundly mating defective mutants may reduce the efficiency of mating by more than five orders of magnitude. Such mutants are generally called “sterile” or “ste” and are caused by defects in the initial pheromone signaling or the subsequent response pathways. In general, there are two basic ways to detect defects in cell and Nuclear Fusion. The first approach uses sensitive methods of detecting either the reduced efficiency of diploid formation or—in the case of Nuclear Fusion—the increased production of unique progeny cells called “cytoductants.” The second approach uses microscopic methods to detect the distinct zygotes in which cell or Nuclear Fusion has failed. It has the virtue of providing information about the nature of the mating defect but—because of the relatively fewer numbers of cells examined—may provide quantitatively less precise data.

Nuclear Fusion prize laudation Nuclear Fusion prize laudation
Nuclear Fusion, 2011Co-Authors: W. BurkartAbstract:Clean energy in abundance will be of critical importance to the pursuit of world peace and development. As part of the IAEA's activities to facilitate the dissemination of Fusion related science and technology, the journal Nuclear Fusion is intended to contribute to the realization of such energy from Fusion. In 2010, we celebrated the 50th anniversary of the IAEA journal. The excellence of research published in the journal is attested to by its high citation index. The IAEA recognizes excellence by means of an annual prize awarded to the authors of papers judged to have made the greatest impact. On the occasion of the 2010 IAEA Fusion Energy Conference in Daejeon, Republic of Korea at the welcome dinner hosted by the city of Daejeon, we celebrated the achievements of the 2009 and 2010 Nuclear Fusion prize winners. Steve Sabbagh, from the Department of Applied Physics and Applied Mathematics, Columbia University, New York is the winner of the 2009 award for his paper: 'Resistive wall stabilized operation in rotating high beta NSTX plasmas' [1]. This is a landmark paper which reports record parameters of beta in a large spherical torus plasma and presents a thorough investigation of the physics of resistive wall mode (RWM) instability. The paper makes a significant contribution to the critical topic of RWM stabilization. John Rice, from the Plasma Science and Fusion Center, MIT, Cambridge is the winner of the 2010 award for his paper: 'Inter-machine comparison of intrinsic toroidal rotation in tokamaks' [2]. The 2010 award is for a seminal paper that analyzes results across a range of machines in order to develop a universal scaling that can be used to predict intrinsic rotation. This paper has already triggered a wealth of experimental and theoretical work. I congratulate both authors and their colleagues on these exceptional papers. W.

X-Pinch Plasma Generation Testing for Neutron Source Development and Nuclear Fusion
Energies, 2018Co-Authors: Hossam A. Gabbar, C.a. Barry Stoute, Daniel Bondarenko, Nicholas Tarsitano, Anas Abdel Rihem, Stefan Sirakov, Shraddhey Jani, Samskruthi MenashiAbstract:Nuclear Fusion is a sought-out technology in which two light elements are fused together to create a heavier element and releases energy. Two primary Nuclear Fusion technologies are being researched today: magnetic and inertial confinement. However, a new type of Nuclear Fusion technology is currently being research: multi-pinch plasma beams. At the University of Ontario Institute of Technology, there is research on multi-pinch plasma beam technology as an alternative to Nuclear Fusion. The objective is to intersect two plasma arcs at the center of the chamber. This is a precursor of Nuclear Fusion using multi-pinch. The innovation portion of the students’ work is the miniaturization of this concept using high energy electrical DC pulses. The experiment achieved the temperature of 2300 K at the intersection. In comparison to the simulation data, the temperature from the simulation is 7000 K at the intersection. Additionally, energy harvesting devices, both photovoltaics and a thermoelectric generator, were placed in the chamber to observe the viable energy extraction.

Plasma physics: A promising advance in Nuclear Fusion
Nature, 2014Co-Authors: Mark HerrmannAbstract:Experiments conducted at the US National Ignition Facility have cleared a hurdle on the road to Nuclear Fusion in the laboratory, encouraging Fusion scientists around the world. See Letter p.343 Efforts to develop Fusion as a viable alternative energy source continue but progress has been slow. In the context of inertial confinement Fusion, in which a fuel target is compressed and heated to initiate Nuclear Fusion, a key experimental goal is to reach a stage where the amount of energy deposited into the fuel during the compression/heating process is exceeded by the amount of energy generated by the induced Fusion reactions. This threshold — the attainment of a 'fuel gain' that is greater than one — has now been reached at the National Ignition Facility in Livermore, California. They used 192 laser beams to heat and compress a fuel pellet to the point at which Nuclear Fusion reactions take place and obtained a yield 10 times greater than previously achieved. Further advances will be required, however, before the Fusion energy yield exceeds the total energy required to compress the fuel pellet.

Role of Nuclear Fusion in future energy systems and the environment under future uncertainties
Energy Policy, 2003Co-Authors: K. Tokimatsu, Junichi Fujino, Satoshi Konishi, Yuichi Ogawa, Kenji YamajiAbstract:Abstract Debates about whether or not to invest heavily in Nuclear Fusion as a future innovative energy option have been made within the context of energy technology development strategies. This is because the prospects for Nuclear Fusion are quite uncertain and the investments therefore carry the risk of quite large regrets, even though investment is needed in order to develop the technology. The timeframe by which Nuclear Fusion could become competitive in the energy market has not been adequately studied, nor has roles of the Nuclear Fusion in energy systems and the environment. The present study has two objectives. One is to reveal the conditions under which Nuclear Fusion could be introduced economically (hereafter, we refer to such introductory conditions as breakeven prices) in future energy systems. The other objective is to evaluate the future roles of Nuclear Fusion in energy systems and in the environment. Here we identify three roles that Nuclear Fusion will take on when breakeven prices are achieved: (i) a portion of the electricity market in 2100, (ii) reduction of annual global total energy systems cost, and (iii) mitigation of carbon tax (shadow price of carbon) under CO2 constraints. Future uncertainties are key issues in evaluating Nuclear Fusion. Here we treated the following uncertainties: energy demand scenarios, introduction timeframe for Nuclear Fusion, capacity projections of Nuclear Fusion, CO2 target in 2100, capacity utilization ratio of options in energy/environment technologies, and utility discount rates. From our investigations, we conclude that the presently designed Nuclear Fusion reactors may be ready for economical introduction into energy systems beginning around 2050–2060, and we can confirm that the favorable introduction of the reactors would reduce both the annual energy systems cost and the carbon tax (the shadow price of carbon) under a CO2 concentration constraint.
