CONSISTENT MODEL FOR INTERACTIONS OF HIGHER-SPIN FERMIONS WITH 0- AND 1/2 - SPIN PARTICLES AND πN - SCATTERING
Authors: Rybachuk E. V. 
Published: December 2023

It is shown that the currents for the interactions of the higher spin fermions must obey the theorem on currents and fields as well as the theorem on continuity of current derivatives. In consequence of the theorem on continuity of current derivatives the current components must decrease at pν→∞, where p is the momentum of the higher spin fermion. The decrease of the currents is ensured by the form factors. The form factor in the vertex function of the interaction of the higher spin fermion with the 0 - and 1/2 - spin particles is derived in agreement with the theorem on continuity of current derivatives. The proposed model of the currents is used for the calculations of the contributions of the higher spin nucleon resonances N*(J) (J is the spin of higher spin fermion) to the s-8 channel amplitudes of the elastic πN-scattering. It is shown that these contributions to the amplitudes decrease at least as at the square of the energy s→∞.

Multiparticle production mechanism is one of the most phenomena that the high-energy physics concerns. In this work, the evolutionary genetic algorithm (GA) is used to optimize the parameters of the back-propagation neural networks (BPNN). The hybrid evolutionary-neuro model (GA-BPNN) was trained to simulate the rapidity distribution 1/N(dN/dY) of positive and negative pions p-Au, p-Ag and p-Xe for p-Ar, p-Xe interactions at lab momentum Plab =100 GeV/c. Also, for total charged, positive and negative pions for interactions at Plab = 200 GeV/c. Finally, total charged particles for p- Pb collision at center-of-mass energy sqrt(s) = 5.02 TeV are simulated. An efficient ANN network with different connection parameters (weights and biases) have been designed by the GA to calculate and predict the rapidity distribution as a function of the lab momentum Plab, mass number (A) and the number of particles per unit solid angle (Y). Our simulated results have been compared with the experimental data and the matching has been clearly found. It is indicated that the developed GA-BPNN model for rapidity distribution was more successful.

Authors: Filonenko N. Yu. , Galdina A. N. 
Published: December 2023

In this paper we study effect of carbon on structural and physical properties of FeB iron monoboride in Fe-B system alloys with carbon content of 0,05-0,90% (wt.) and boron content of 9,0-15,0% (wt.), the rest is iron. To determine the physical properties of alloys we use microstructure analysis, X-ray microanalysis and X-ray structural analysis. Carbon doping of FeВ iron monoboride leads to a feeble lattice strain and effects on the physical characteristics of boride. Using the quasi-chemical method we estimate the temperature dependence of the boride free energy and carbon solubility limit in FeB monoboride. Carbon can substitute up to 4% ofboron atoms in FeB phase depending on the temperature. At high temperatures the carbon solubility in this phase increases. The obtained estimated data is in good agreement with experiment.

Authors: Barannik E. A. , Matchenko O. S. 
Published: December 2023

The previously developed continuum model of ultrasound wave scattering from inhomogeneities of mass density and compressibility was generalized in the present paper to the case of dynamically changing sensitivity function of ultrasound diagnostic system. The general expression relating the full power spectrum of Doppler response signal from the region of interest to spectral characteristics of scattering inhomogeneities movement and components of the probing ultrasound fields on spatial and temporal harmonics was obtained. The results of the work can be useful for the analysis of spectra obtained by means of modern diagnostic systems with dynamic focusing of transmitted beams by synthetic aperture method.

Authors: Tyutyunnikov V. I. 
Published: December 2023

The spectral parameters ultrafine particles Zn2SiO4-Mn, precipitated on the substrate in a magnetic or electric field have been investigated. For getting fine particles industrial phosphor K-60 (Zn2SiO4-Mn) was used. Luminescence spectra were obtained on a sample when exposed to ultraviolet light or a beam of charged oxygen ions. When excited by ultraviolet spectral characteristics have difference for samples with different dimensions of the crystals. As for the industrial design luminescence spectrum had a band with λmaх = 521 nm, and for the ultrafine crystals willemite spectral band had λmax = 550 nm. Analysis ionoluminescence spectra showed that the reduction of crystal size Zn2SiO4-Mn not affect the spectral characteristics of the excitation beam with low energy oxygen ions. The luminescence spectrum when exposed to low-energy ions (1-3 KeV) has a band with λmax = 521 nm and a half-width Δλ = 41 nm. When measuring the width of the forbidden zone has been established bandgap dependence on the size of the phosphor crystals. The width of the band gap increases with decreasing crystal size to nanoscale sizes. A significant effect was obtained when deposited on a substrate in the nanoscale crystal magnetic or electric field. As for the industrial design the bandgap was 4.16 eV, and for the besieged in the magnetic and electric field of 4.27, 4.29 eV, respectively.

Authors: Reddy R. Chandra Sekhar , Gunisetty Ramasekhar 
Published: December 2023

The advancement of aircraft technology has presented manufacturers with new criteria and problems for the functioning of their devices. It is essential that, in order to guarantee the secure operation of aerospace machinery, the failure mechanisms be identified and the operational durability of critical structural components be improved as quickly as possible. New aviation materials have been developed in modern years. In an aviation engine, engine oil lubricates, cools, washes, maintains against rust, decreases sound, and accelerates. Most important is lubrication. All mechanical components would burn out if not maintained. The aim of this work is to minimize costs by extending the operational life of aircraft components (mechanical and motor parts) and enhancing fuel mileage and flying distance. Based on the importance of the inspiration on magnetohydrodynamic Aluminum Oxide-Cobalt hybrid nanofluid flow over a stretching surface (SS) in the existence of porous medium, and thermal radiation are investigated. In this model we used Engine oil mixed with Aluminum Oxide and Cobalt nanoparticles. By using the suitable self-similarity variables, the PDE is transformed into ODEs. After then, the dimensionless equations are solved by using the Maple built in BVP Midrich scheme. Graphs and tables explain how the operational factors affect fluid flow efficiency. Compared to nanofluids, hybrid nanofluids have a better heat transfer rate.

Published: December 2023

INTRODUCTION: Type 1 diabetes is a chronic disease characterized by a selective loss of pancreatic ?-cells with a disproportionate recent increase at ages under 5-years old. Its etiology is multifactorial, to which immune factors contribute through pancreatic autoantibodies. Our main aim is to assess whether the type of pancreatic autoantibody influence the clinical symptoms, glycated hemoglobin and glycemia at diagnosis of type 1 diabetes in children diagnosed under ten-years of age.METHODS: Observational, retrospective and analytical study carried out with a total of 95 patients included. We compared two groups (aged ?60 months and >60 months) and each type of autoantibody (positive/negative) regarding demographic, immune, clinical and laboratory characteristics. The autoantibodies studied were islet cell autoantibodies (against cytoplasmic proteins in the ?-cell), antibodies to glutamic acid decarboxylase, anti-insulin and anti-zinc transporter 8. The impact of autoimmunity, glycated hemoglobin, gender and age on clinical and laboratory parameters of these children was analyzed.RESULTS: Children diagnosed over 60 months had a higher glycated hemoglobin value (p=0.005) and this laboratory parameter was the only one that showed an impact on the initial presentation as diabetic ketoacidosis (CI95%: OR=1.66;p=0.001). The value of glycemia at admission showed to be influenced negatively by age (?=--0.25;p=0.022) and positively by glycated hemoglobin (?=0.35;p=0.001). None of the autoantibodies evaluated seemed to interfere in the clinical and laboratory manifestations of type 1 diabetes.CONCLUSION: Demographic, clinical and laboratory characteristics showed no statistically significant differences between two groups of positive/negative pancreatic autoantibodies analyzed. It is crucial to develop further studies in the scope of autoimmunity that allow to structure potential immune phenotypes and assist in the discovery of new therapeutic targets.

Published: December 2023

INTRODUÇÃO: A antibioterapia profilática é utilizada de forma a prevenir a recorrência de infeções do trato urinário (ITUs), contudo a crescente problemática da resistência à antibioterapia ao longo dos últimos anos tem levado à procura de alternativas. O objetivo desta revisão foi avaliar a evidência disponível acerca da eficácia do hipurato de metenamina como alternativa à antibioterapia na profilaxia das ITUs recorrentes.MÉTODOS: As fontes de dados consultadas foram The Cochrane Library, MEDLINE/PubMed, DARE, TRIP Medical Database, Canadian Medical Association Practice Guidelines Infobase e National Guideline Clearinghouse. Foi realizada a pesquisa de meta-análises, ensaios clínicos controlados e aleatorizados, estudos observacionais e guidelines escritos em inglês ou português, publicados entre janeiro de 2012 e maio de 2022, tendo sido utilizados os termos MeSH “methenamine” e “urinary tract infections”. O nível de evidência e a força de recomendação foram avaliados com base na escala Strength of Recommendation Taxonomy (SORT) da American Family Physician.RESULTADOS: Dos 106 resultados obtidos inicialmente, foram selecionados 3 artigos, 2 ensaios clínicos controlados e aleatorizados e 1 estudo observacional retrospetivo. A evidência encontrada nestes estudos revelou que o hipurato de metenamina é equiparável à antibioterapia profilática na prevenção das ITUs recorrentes.CONCLUSÃO: Esta revisão permite concluir que o hipurato de metenamina poderá surgir assim como uma possível alternativa viável e segura à antibioterapia profilática demonstrando não ser inferior a esta (SORT B), tendo a vantagem clara de não contribuir para a problemática crescente que é a resistência antibiótica.
Contraceptive Methods and Female Sexual Function: A Literature Review
Authors: Frois Ana 
Published: December 2023

Contraceptives can affect libido, and method choice should consider possible effects on female sexual function. This review aims at identifying the role of different contraceptive methods on female sexual function, thus allowing for better clinical counseling. This review, performed in August/2022, included 13 reviews and 32 clinical trials. The levonorgestrel intrauterine system, vaginal ring, and transdermal patch showed mainly positive or neutral effects. The subcutaneous implant and combined oral contraceptives led to mixed results. The progestogen-only oral contraceptive and the DMPA intramuscular injection were associated with mainly negative sexual effects. The copper uterine device had no impact on female sexual function. Sterilization had mixed psychological effects. Adequate counseling, replacement of the contraceptive method, and, in specific cases, pharmacologic treatment may improve contraceptive-associated female sexual dysfunction. More large-scale studies are needed to allow for specific recommendations regarding each contraceptive method and the production of clinical guidelines for these situations.
