Quark-Parton Fusion and the Scaling of Hadron Production at the LHC  [PDF]
Alexey Borisovich Kurepin, Evgeny Vladimirovich Karpechev
Journal of Modern Physics (JMP) , 2026, DOI: 10.4236/jmp.2026.179048
Abstract: Hadron production, including pions, kaons and antiprotons, in proton-proton collisions at an energy of s = 7 TeV at the ALICE facility has been studied. For the data analysis, a generalized parton model was used, which takes into account the interaction of two partons in colliding beams and the production of new particles. Considering the effects of parton fusion and compound state formation results in a scaling dependence of the hadron production cross sections of different species.
Photon Is Shortened Name for Electromagnetic Field but Not a Particle  [PDF]
Marat Vladimirovich Guryev
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.69159
Abstract: We well know that photon concept is self-contradictory because we assume that it is a particle with wave properties. This contradiction insensibly spoils our subconscious thinking. It is shown in the article that photon has no 4-coordinates for work within atomic quantum electrodynamics (QED). This implies that actually photon is not a particle. I draw attention that QED is the most precise theory developed by humankind. It is noticed that terms photon and electromagnetic field in practice are in use as synonyms. These results validate the title of the article and exempt us from contradictions within quantum mechanics.
Particles Actually Represent the Names of Types of Waves  [PDF]
Marat Vladimirovich Guryev
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.612207
Abstract: It is accepted that quantum mechanics (QM) describes motion of waves and particles. Therefore, we must use wave-particle duality (WPD), which is usually considered as one of the foundations of QM; however, WPD is well known as a self-contradictory concept. These contradictions insensibly spoil our subconscious thinking about the micro-world (MW). This article shows that known trials to solve these contradictions are erroneous. Quantum jumps (QJs) are shown to be very lame arguments for the real existence of particles. I offer rejecting the concept of particles and using their names as labels for types of corresponding waves. Thus, we can discard contradictions created by WPD. This approach is validated in the article by careful analysis of real calculation methods of quantum electrodynamics (QED). For the first time, it is noticed that proper 4-coordinates of particles are not in use in real calculations in QED. This implies that particles do not take part in real calculations, which describe properties of atoms and molecules. It follows that particles do not exist as such. Therefore, we must acknowledge that we actually use the names of “particles” merely as names of types of given waves, but not as real, physical objects.
Numerical Modeling of the Vapour Vortex Formation in the Short Heat Pipes  [PDF]
Arkady Vladimirovich Seryakov
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2019, DOI: 10.4236/jhepgc.2019.51013
Abstract: The results of the numerical studies of vortex formation inside short heat pipes (HP’s) with profiled vapour channel in the Laval-liked nozzle form are presented. For the first time, it was found that the vapour vortex of moist compressible vapour flow in the cooled part of vapour channel changes its rotational motion direction. The rotation direction of the toroidal vapour vortex, obtained by solving the Navier Stokes equations is dependent on the heat power value, entering to the HP’s evaporator. With low heat power loads the rotational direction of the circular toroidal vapour ring due to the Coanda effect and sticking moving vapour jets to the channel’s walls occurs from the periphery to the longitudinal axis of the vapour channel. While the heat power load increasing, the direction of the circular toroidal vapour ring rotation changes to the opposite, from the longitudinal axis to the periphery of the vapour channel. The thickness of the formed working fluid condensate film located under the toroidal vapour vortex also related to the evaporator heat power load and the associated toroidal vapour vortex rotation direction. The numerical thickness calculation of the formed working fluid condensate film located under the toroidal vapour vortex was compared with experimental values, obtained by capacitive sensors. The thickness values of the calculated condensate film thickness and experimentally measured values using capacitive sensors are close in magnitude order.
The Solving of the Inverse Thermal Conductivity Problem for Study the Short Linear Heat Pipes  [PDF]
Arkady Vladimirovich Seryakov
Engineering (ENG) , 2022, DOI: 10.4236/eng.2022.146018
Abstract: The results of studies by solving the inverse thermal conductivity problem of the heat capacity of evaporator of the short linear heat pipes (HP’s) with a Laval nozzle-liked vapour channel and intended for cooling spacecraft and satellites with strict take-off mass regulation are presented. Mathematical formulation of the inverse problem for the HP’s thermal conductivity in one-dimensional coordinate system is accompanied by the measurement results using the monotonic heating method in a vacuum adiabatic calorimeter the HP’s surface temperatures along the longitudinal axis over the entire temperature load range, thermal resistance, and arrays of thermal power data on the evaporator Qev and vortex flow calorimeter Qcond for the condensation surface allow us to estimate the average value of the evaporator heat capacity Cev by solving the inverse thermal conductivity problem in the HP’s evaporator region. Since at the beginning of working fluid boiling for a certain time interval, the temperature of the capillary-porous evaporator remains close to constant, and with the continuation of heating and by solving the inverse thermal conductivity problem, it becomes possible to calculate the heat capacity of the working evaporator and the evaporation specific heat of the boiling working fluid and compare it with the table values.

Influence of Fe Content on Tool Galling in Ironing Aluminum Beverage Cans  [PDF]
Aleksey Vladimirovich Andrianov, Elena Gennadievna Kandalova, Evgeniy Vladimirovich Aryshensky
Materials Sciences and Applications (MSA) , 2014, DOI: 10.4236/msa.2014.510073
Abstract:
Insoluble constituents in 3104 alloy for beverage cans manufacturing play an important role in deep ironing process. This paper studies the effect of Fe content in the alloy on volume fraction of the constituents Al6(Fe, Mn)3 and Al12(Fe, Mn)3Si and its influence on ironing die pickup. It is shown that with Fe content increase, the amount of these constituents rises that helps prevent tool galling. Trials made at a can plant showed less ironing die changeovers at bodymakers. The optimum Fe content for aluminum can production can be considered between 0.47% and 0.53% that corresponds to 2.0% - 2.3% of insoluble constituent volume fraction. Greater amounts than this cause problems with excessive constituent particle formation and earing; smaller amounts result in increased ironing die galling.
Asymptotic Analysis of Periodic Solutions in Liénard-Type Dynamic Systems  [PDF]
Borys Basok, Volodymyr Vladimirovich Gotsulenko
Journal of Applied Mathematics and Physics (JAMP) , 2026, DOI: 10.4236/jamp.2026.141014
Abstract: This paper investigates the existence, stability, and asymptotic properties of periodic solutions in nonlinear dynamical systems of Liénard type arising in thermohydro-gas-dynamic models. Starting from a physical formulation describing self-oscillations in fluid and gas flows, the governing equations are reduced to a two-dimensional system with a nonlinear characteristic function. Using the Lindstedt-Poincaré method, we construct an asymptotic expansion of the periodic solution in powers of the small parameter, which characterizes the nonlinearity of the system. The approach eliminates secular terms, ensuring uniform validity of the solution over time. Explicit formulas for the amplitude and frequency corrections are derived, and conditions for the existence and stability of the limit cycle are established based on Andronov’s theorem. The results provide analytical insight into the mechanisms of self-oscillation in engineering applications such as compressors and thermoacoustic systems.

Image Analysis in Microbiology: A Review  [PDF]
Evgeny Puchkov
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.415002
Abstract:
This review is focused on using computer image analysis as a means of objective and quantitative characterizing optical images of the macroscopic (e.g. microbial colonies) and the microscopic (e.g. single cell) objects in the microbiological research. This is the way of making many visual inspection assays more objective and less time and labor consuming. Also, it can provide new visually inaccessible information on relation between some optical parameters and various biological features of the microbial cul-tures. Of special interest is application of image analysis in fluorescence microscopy as it opens new ways of using fluorescence based methodology for single microbial cell studies. Examples of using image analysis in the studies of both the macroscopic and the microscopic microbiological objects obtained by various imaging techniques are presented and discussed.
