Atomic Motion in Single H2_{2} and D2_{2} Molecule Junction Induced by Phonon Excitation

We have investigated Au atomic contacts in H$_{2}$ and D$_{2}$ environment by conductance measurement and $dI/dV$ spectroscopy. A single H$_{2}$ or D$_{2}$ molecule was found to bridge Au electrodes. In the case of the Au/H$_{2}$/Au junction, symmetric peaks were observed in $dI/dV$ spectra, while they were not observed for the Au/D$_{2}$/Au junction. The shape of the peaks in $dI/dV$ spectra originated from the structural change of the single molecule junction induced by the phonon excitation. The structural change could occur only for the Au/H$_{2}$/Au junction. The difference in the two single molecule junctions could be explained by larger zero point energy of Au-H$_{2}$ vibration mode than that in the Au/H$_{2}$/Au junction.Comment: 5 pages, 4 figures, to be appear in Phys.

Исследование, модификация и практическое применение низкоэнергетической ядерной установки Росси

Авторами была поставлена цель - исследовать установку Росси, найти общее теоретическое объяснение процессу, а также найти практическое применение данной технологии. В марте 2014 года была проведена независимая комиссия, описавшая процесс наблюдения за установкой, стабильно находившейся в рабочем состоянии 32 дня [1]. До этого проводилась подобная экспериментальная проверка, которая также была учтена в ходе работы. [2]. Подробный, научный принцип работы устройства остается неизвестным. Была доказана возможность данной реакции и выдвинуты основные предположения о методе работы. Найдено наиболее рентабельное использование технологии на данном этапе исследований. Рассчитана стоимость реализации, прибыль. Был проведен сравнительный анализ конкурентов, на основе которого был сделан вывод о рентабельности данного проекта

Quantitative analysis of hemodynamics of congested island flaps under leech therapy

Background A congested flap is a good indication for leech therapy. However, determining the appropriate number of leeches as well as the appropriate application time in clinical cases is difficult. We analyzed hemodynamics in rabbit island flaps under leech therapy to find a suitable clinical procedure for determining the appropriate number of leeches to be used and the duration of therapy. Methods Island flaps were raised in 35 rabbit ears, and congestion was induced by venous clamping. Treatment involved use of 1 or 3 leeches and was begun 60 minutes after venous occlusion. Flaps were examined for area of surviving tissue, alterations in transcutaneous oxygen and carbon dioxide tension (TcPO2 and TcPCO2), and flow volume. Arteriole and venule diameters and flow velocities were examined microscopically. Results Flap survival area in the 3-leech therapy group was significantly larger than the 1-leech therapy group and the control group. With 3- leech therapy, TcPCO2 decreased significantly, as did arteriole and venule diameters. After clamp release, TcPCO2 and venule diameter continued to decrease in this group, and flow velocity increased significantly. Conclusions Leech therapy may salvage compromised flaps by replacing congested blood with new arterial blood and thus maintaining flap viability. TcPO2 and TcPCO2 monitoring may help evaluate the therapeutic effect and determine the appropriate number of leeches to apply and the duration of therapy
