Detection of Aortic Graft Infection Combined with a Pelvic Abscess Using 18F-FDG PET/CT in a Patient with FUO

Authors: Mohammed Shah Alam, Auradkar Manisha, Wei Guan, Hu-bing Wu, Quan-shi Wang, Wen-lan Zhou
Comments: 3 Pages.

Aortic graft infection (AGI) is an uncommon but severe late complication of associated with vascular surgery. Early detection is important because of high mortality. Clinical findings often are nonspecific. Some of AGI patients present with FUO. A 67-year-old female received an endovascular aneurysm repair for abdominal aortic aneurysm. After 2 years of surgery she suffered from recurrent fever for 8 months and sometimes body temperature peaked at 40°C. Laboratory examinations show all are increased. Multiple modalities of imagine has been performed including x-ray, USG and CT. To find out the cause of FUO he was referred to perform 18F-FDG PET/ CT for further evaluation. The PET/CT images revealed the extent of the inflammation around grafts and the pelvic abscess, which helped to confirm the cause of FUO and establish the diagnosis of AGI. That indicates 18F-FDG PET/CT is a reliable modality for the FUO patients who has undergone endovascular aneurysm repair

Microworld_33. Electromagnetic Engines Without Moving Parts

Authors: N.N.Leonov
Comments: 11 Pages. English and russian texts.

There can be two kinds of electromagnetic engines developed that would be free of moving macroscopic parts. One of them is EmDrive wherein magnetron launches a vortex-like whirl that generates ethereal jet thrust. Another is a capacitor-type photon engine that utilizes “motive force” of photon.

Microworld_32. Nature of the “Impossible” EmDrive Jet Thrust

Authors: N.N.Leonov
Comments: 13 Pages. English and russian texts. Вас устраивает качество перевода на English?

Jet thrust of the “impossible” electromagnetic engine called ЕmDrive is created by the magnetic whirl that is constantly pumping through flows of ambient ether which in their turn are keeping the magnetic whirl stable.

Microworld 31. Arrow of Time

Authors: N.N.Leonov
Comments: 11 Pages. English and russian texts

Refusal of the “arrow of time” in physics is a result of the academic insufficiency of the quantum physics and relativity theory

Electric Cumulative Thermonuclear Reactors

Authors: Alexander Bolonkin
Comments: 22 Pages.

During past sixty years, scientists spent tens of billion US dollars attempting to develop useful thermonuclear energy. However, they cannot yet reach a sustained stable thermonuclear reaction. They still are promising publically, after another 15 – 20 years, and more tens of billions of US dollars to finally design the expensive workable industrial installation, which possibly will produce electric energy more expensive than current heat, wind and hydro-electric power generation stations can in 2016. The author offers the new, small and cheap electric cumulative thermonuclear reactors, which increases the temperature and pressure of its nuclear fuel by millions of times, reaches the required ignition stage and, ultimately, a constant well-contained thermonuclear reaction. Electric Cumulative AB Reactors contain several innovations to achieve its power output product. Chief among them in electric thermonuclear reactors are using moving cumulative explosives and an electric discharge, which allows to accelerate the fuel and special nucleus to very high speed which (as shown by integral computations) compresses the fuel thousands times and heats the fuel by electric impulse to hundreds of millions degrees of temperature. In electric cumulative version of AB thermonuclear reactors, the fuel nucleus are accelerated by high electric voltage (15 ÷ 60 kV) up the hundreds millions degree and cumulative compressed into center of the spherical fuel cartridge. The additional compressing and combustion time the fuel nucleus may have from heavy nucleus of the fuel cartridge. The main advantages of the offered method are very small fuel cartridge (11-18 mm) of the full reactor installation (reactor having spherical diameter (0.3 - 3 m), using the thermonuclear fuel at room-temperature and achieves the possibility of using the offered thermonuclear reactor for transportation (ships, trains, aircrafts, rockets, etc.). Author gives theory and estimations of the suggested reactors. Author also is discussing the problems of converting the received thermonuclear energy into mechanical (electrical) energy and into rocket thrust. Offered small micro-reactors may be used as heaves (propellant after ignition, fusee) for small artillery nuclear projectiles and bombs.

Emissivity: A Program for Atomic Emissivity Calculations

Authors: Taha Sochi
Comments: 20 Pages.

In this article we report the release of a new program for calculating the emissivity of atomic transitions. The program, which can be obtained with its documentation from our website, passed various rigorous tests and was used by the author to generate theoretical data and analyze observational data. It is particularly useful for investigating atomic transition lines in astronomical context as the program is capable of generating a huge amount of theoretical data and comparing it to observational list of lines. A number of atomic transition algorithms and analytical techniques are implemented within the program and can be very useful in various situations. The program can be described as fast and efficient. Moreover, it requires modest computational resources.

Atomic and Molecular Aspects of Astronomical Spectra

Authors: Taha Sochi
Comments: 238 Pages.

In the first section we present the atomic part where a C2+ atomic target was prepared and used to generate theoretical data to investigate recombination lines arising from electron-ion collisions in thin plasma. R-matrix method was used to describe the C2+ plus electron system. Theoretical data concerning bound and autoionizing states were generated in the intermediate-coupling approximation. The data were used to generate dielectronic recombination data for C+ which include transition lines, oscillator strengths, radiative transition probabilities, emissivities and dielectronic recombination coefficients. The data were cast in a line list containing 6187 optically-allowed transitions which include many C II lines observed in astronomical spectra. This line list was used to analyze the spectra from a number of astronomical objects, mainly planetary nebulae, and identify their electron temperature. The electron temperature investigation was also extended to include free electron energy analysis to investigate the long-standing problem of discrepancy between the results of recombination and forbidden lines analysis and its possible connection to the electron distribution. In the second section we present the results of our molecular investigation; the generation of a comprehensive, calculated line list of frequencies and transition probabilities for H2D+. The line list contains over 22 million rotational-vibrational transitions occurring between more than 33 thousand energy levels and covers frequencies up to 18500 cm-1. About 15% of these levels are fully assigned with approximate rotational and vibrational quantum numbers. A temperature-dependent partition function and cooling function are presented. Temperature-dependent synthetic spectra for the temperatures T=100, 500, 1000 and 2000 K in the frequency range 0-10000 cm-1 were also generated and presented graphically.

Nuclear Binding Energy Curve

Authors: Ranganath G. Kulkarni
Comments: 4 Pages.

An equation for nuclear binding energy per nucleon is found that agree well with observations. The interpretation indicates that we need to explore physical variables involved in the nuclear force or nuclear binding energy.
