Nuclear products of cold fusion by TSC theory

Anomalous excess heat without corresponding nuclear radiations have been claimed by cold fusion experiments with metal-deuterium systems (heat/4 He correlation by Miles, McKubre, et al., very weak alpha-particles by Roussetskii and Lipson, et al, very weak neutron emission by Boss, Takahashi, et al) since 1990s. These claims are challenging to making theoretical models to elucidate underlying physical mechanisms. The author has elaborated the TSC (tetrahedral symmetric condensate) theory for either the metalD systems (ACS LENRSB Vol.1 and Vol.2, ICCF17, etc.) or the Ni-H systems (JCMNS Vol.9, JCF12, ICCF17, etc.). The author's past effort has been concentrated on the initial and intermediate states of TSC condensation and strong interaction processes, and the prediction of nuclear products by the final state nuclear interactions have not been deeply studied. In the JCF-13 paper (Nucleon Halo Model of 8 Be* by Takahashi-Rocha), we have started the study on the final state interaction of 4D/TSC fusion

Automated closed-chamber measurements of methane fluxes from intact leaves and trunk of Japanese cypress

Continuous in situ measurements of methane (CH4) fluxes from intact leaves and trunk of Japanese cypress (Chamaecyparis obtusa Sieb. et Zucc) were conducted in a temperate forest from August 2009 to August 2010. An automated closed-chamber system, which was used to evaluate CO2 exchange between the atmosphere and forest ecosystems, was coupled to a laser-based instrument to monitor CH4 concentrations. Temporal changes in CH4 concentrations from the foliage and trunk were measured at one-second intervals during chamber closure to determine CH4 fluxes between the leaf and trunk surfaces and the atmosphere. While recent studies have suggested that some plants emit CH4 under aerobic conditions, emission or uptake of CH4 in detectable amounts with our experimental system, by intact leaves or the trunk of C. obtusa, was not significantly observed throughout the measurement period

Impartial and Partizan Restricted Chocolate Bar Games

In this paper, we consider impartial and partizan restricted chocolate bar games. In impartial restricted chocolate bar games, players cut a chocolate bar into two pieces along any horizontal or vertical line and eat whichever piece is smaller. If the two pieces are the same size, a player can eat either one. In constrast, partizan restricted chocolate bar games include players designated as Left and Right and chocolate bars with black and white stripes. Left cuts the chocolate bar in two as above and eats the part with fewer black blocks. Similarly, Right cuts the bar and eats the part with fewer white blocks. A player loses when they cannot eat the remaining chocolate bar. We provide formulas that describe the winning positions of the previous player, Right, and Left players. We also present an interesting similarity in the graphs of previous players' winning positions for impartial and partizan chocolate bar games

A mass-flow-calorimetry system for scaled-up experiments on anomalous heat evolution at elevated temperatures

We have been studying phenomena of anomalous heat evolution from hydrogen-isotope-loaded nanocomposite samples at elevated temperatures as well as at room temperature using a twin absorption system. Recent experiments have used Ni-based nano-composite samples; Pd1 Ni7/ZrO2 ("PNZ"), Ni/ZrO2 ("NZ"), Cu0.081 Ni0.36/ZrO2 ("CNZ") and Cu0.21Ni0.21/ZrO2 ("CNZII"). The results of measurements have been presented in the meetings of the 12th Japan CF-Research Society (JCF12), the 17th International Conference on Condensed Matter Nuclear Science (ICCF17) and the 13th Japan CFResearch Society (JCF13), and have been/will be published in [3], [4] and [5], respectively. These will be summarized, and the time-dependent data will be re-analyzed in another paper by A. Takahashi in this Conference for speculating heat releasing mechanisms during the several-week-lasted phase of D(H)-loading into the nano-composite samples. As will be shown there, a lot of interesting, even astonishing, features are involved; burst-like heat release with anomalously high values of differential heat of sorption (η) reaching ca. 600 eV/atom-H, large values of integrated heat reaching ca. 800 eV/atom-Ni from the CNZ sample absorbing H, and abrupt desorption with absorbed energy of 50 - 80 eV/atom-Ni observed almost exclusively in the first 573-K run for each sample. To confirm the interesting phenomena, repeated measurements with improved signal-to-noise ratio are required. Since the easiest way for this is to increase the sample amount, we have fabricated a reaction chamber with a ten-times-larger volume than in-being one. Another important improvement is a mass flow calorimetry applied to the system using an oil coolant with a boiling point of 390 deg-C. Moreover, to make residual gas mass spectral analysis in A = 1 - 6 amu range, a QMA system is going to be installed in the line of the apparatus. In the presentation we will show the schematics of this new oil-cooling mass-flow calorimetry system for observing anomalous heat evolution in H(D)-gas charging to Ni-based nano-composite samples and for calibration runs using blank alumina sample

One year of continuous measurements of soil CH4 and CO2 fluxes in a Japanese cypress forest: Temporal and spatial variations associated with Asian monsoon rainfall

We examined the effects of Asian monsoon rainfall on CH[4] absorption of water-unsaturated forest soil. We conducted a 1 year continuous measurement of soil CH[4] and CO[2] fluxes with automated chamber systems in three plots with different soil characteristics and water content to investigate how temporal variations in CH[4] fluxes vary with the soil environment. CH[4] absorption was reduced by the “Baiu” summer rainfall event and peaked during the subsequent hot, dry period. Although CH[4] absorption and CO[2] emission typically increased as soil temperature increased, the temperature dependence of CH[4] varied more than that of CO[2], possibly due to the changing balance of activities between methanotrophs and methanogens occurring over a wide temperature range, which was strongly affected by soil water content. In short time intervals (30 min), the responses of CH[4] and CO[2] fluxes to rainfall were different for each plot. In a dry soil plot with a thick humus layer, both fluxes decreased abruptly at the peak of rainfall intensity. After rainfall, CO[2] emission increased quickly, while CH[4] absorption increased gradually. Release of accumulated CO[2] underground and restriction and recovery of CH[4] and CO[2] exchange between soil and air determined flux responses to rainfall. In a wet soil plot and a dry soil plot with a thinner humus layer, abrupt decreases in CH[4]fluxes were not observed. Consequently, the Asian monsoon rainfall strongly influenced temporal variations in CH[4] fluxes, and the differences in flux responses to environmental factors among plots caused large variability in annual budgets of CH[4] fluxes

Measurement of methane flux over an evergreen coniferous forest canopy using a relaxed eddy accumulation system with tuneable diode laser spectroscopy detection

Very few studies have conducted long-term observations of methane (CH4) flux over forest canopies. In this study, we continuously measured CH4 fluxes over an evergreen coniferous (Japanese cypress) forest canopy throughout 1 year, using a micrometeorological relaxed eddy accumulation (REA) system with tuneable diode laser spectroscopy (TDLS) detection. The Japanese cypress forest, which is a common forest type in warm-temperate Asian monsoon regions with a wet summer, switched seasonally between a sink and source of CH4 probably because of competition by methanogens and methanotrophs, which are both influenced by soil conditions (e.g., soil temperature and soil moisture). At hourly to daily timescales, the CH4 fluxes were sensitive to rainfall, probably because CH4 emission increased and/or absorption decreased during and after rainfall. The observed canopy-scale fluxes showed complex behaviours beyond those expected from previous plot-scale measurements and the CH4 fluxes changed from sink to source and vice versa

Anomalous exothermic and endothermic data observed by Nano-Ni-composite samples

This is an experimental paper summarizing the observations of anomalous data on excess heat, D(H)-loading and abrupt desorption with endothermic heat sink in Ni-nano-composite samples under D(H)-gas charging at both room and elevated temperatures, done by Kobe-Technova group in 2012-2013. Referring to our JCF12 paper (Y. Miyoshi et al., JCF-12-1) on Pd1Ni7/ZrO2 samples, experimental procedure and results reported for Ni/ZrO2, Cu0.21Ni0.21/ZrO2 and Cu0.08Ni0.36/ZrO2 samples (partially reported in our JCF13-15 paper by Sakoh et al.) will be summarized. We have reanalyzed time-dependent data for speculating heat releasing mechanisms during the long (several weeks) lasted phase of D(H)-loading-into-nano-metal. It seems that competing process of D(H)-gas sorption and desorption at the surface of nano-powders would be attributed to the mechanism. Burst-like heat peaks of η-values (in unit of eV per D(H)-take-in/out) were observed with anomalously high values reaching 600 eV/H-sorption, and with smaller [eta]-values for isotopic Dsorption than H-sorption, at 573K. Integrated heat values for several-week runs were reached at the levels of ca. 800eV/atom-Ni for Cu0.08Ni0.36/ZrO2 samples, which were about 10 times larger than those of Ni/ZrO2 samples and about 4 times larger than those of Cu0.21Ni0.21/ZrO2 samples, at temperatures of 523 to 573K
