description: This paper explores the applications of the theory of extrema to solving practical problems. A number of applied problems from mechanics, geometry, physics, and engineering are analyzed using methods of mathematical analysis. For each problem, an appropriate mathematical model is constructed, and optimal solutions are obtained by determining the maxima and minima of single-variable functions. Critical points are identified using firstand second-order derivatives. The results demonstrate that the theory of extrema is a universal and effective tool for optimizing real-world processes and plays an important role in integrating theory and practice in teaching mathematical analysis

Stopping power of the 12C carbon nucleus for a projectile in p12C collisions at a momentum of 4.2 GeV/s
type: item
description: In this paper, the stopping power of carbon nuclei in interactions of protons with a momentum of 4.2 GeV/s with carbon nuclei is studied, based on the study of multiple spectra of secondary charged particles, π- mesons, π+ mesons and protons of the participants depending on the degree of centrality. The obtained experimental data are compared with the calculations of the theoretical CEM model (cascade-evaporation model) and the FRITIOF model with and without taking into account Δ+ and Δ0-isobars. It is shown that in central interactions the primary proton loses a significant part of its energy and the fraction of leading protons increases, while the fraction of target protons is maximal in events with Q = 1 and decreases rapidly in events with Q ≥ 5. This result reflects the softening of the spectrum of fast target protons as the centrality of collisions increases.

Effect Of Gamma And Electron Irradiation On The Optical Characteristics Of Mgf2 Crystals And Ceramics
type: item
description: This paper examines the effects of γ-ray and electron irradiation on the optical properties of MgF2 crystals and ceramics. The samples were irradiated with γ-rays over a wide dose range and with a 4 MeV electron beam in the fluence range of 1014–1015 cm-2. A combination of methods was used to study the opaque ceramic samples, including optical and infrared transmission and reflectance measurements, elemental and phase composition analysis, determination of the crystal structure of the near-surface layer, and scanning electron microscopy. For the first time, a deviation in the stoichiometric composition of the near-surface layer of fluoride materials after irradiation was detected using two independent methods-local elemental analysis using characteristic X-rays and IR spectroscopy. The appearance of oxygen in the surface layer was established, which may be related to radiation-induced processes leading to fluorine loss and changes in the chemical composition of MgF2. The obtained results expand our understanding of the mechanisms of radiation-induced defect formation and modification of the optical properties of MgF2 crystals and ceramics.

Optimization Of The Process Of Heating An Oil And Gas Condensate Mixture By Light Naphtha Vapor In Heat- Exchanger Condenser 10e04
type: item
description: This study investigates the optimization of heating a 30% oil-70% gas condensate mixture in the industrial shell-and-tube heat exchanger-condenser 10E-04 at the Bukhara Oil Refinery. The mixture flow rate was 105,508 kg/h, with an inlet temperature of 96.1°C and a naphtha vapor condensation temperature of 136.6°C. A refined mathematical model accounting for temperature-dependent changes in density (768- 744 kg/m3), heat capacity (2180-2310 J/kg·°C), and viscosity (0.0032-0.0023 Pa·s) was applied, improving calculation accuracy by 20-30%. The overall heat transfer coefficient was 270 W/m2·K. Analysis showed that at the regulated outlet temperature of 111.7°C, only 72% of the 273 m2 heat transfer surface is effectively utilized. The optimal outlet temperature was determined as 107.3°C, corresponding to a required surface of 220 m². At this condition, pump power consumption is 15.4 kW and the minimum specific technological cost is 285.12 sum/kg. The optimized regime reduces effective heat transfer surface by 19% and lowers technological costs by approximately 3-4%, revealing additional thermal capacity reserves of the apparatus.

Comparison Of Runge–Kutta, Multistep, And Crank Nicolson Schemes For Time Integration In The Numerical Solution Of The Heat Equation
type: item
description: In this paper, three time-integration approaches for the numerical solution of the one dimensional heat conduction equation are compared, namely one-step Runge Kutta methods, Adams-type multistep methods, and the Crank–Nicolson scheme. As a model problem we consider the classical heat equation with Dirichlet boundary conditions, discretized in space by second-order central finite differences. The resulting system of linear ODEs is integrated in time using the fourth-order Runge Kutta method, the three step Adams Bashforth Moulton predictor–corrector pair, and the Crank–Nicolson scheme, which is equivalent to the trapezoidal rule. We analyze the local and global orders of accuracy, stability properties, and computational efficiency of these methods.

Generation And Aggregation Of Radiation Defects In Lif Crystals Under Gamma Irradiation
type: item
description: The absorption spectra of LiF crystals irradiated with gamma radiation in a 60Co source at a power of 1200 R/s in the dose range of 105–108 R and a temperature of 320 K were studied. Gamma irradiation initially produces F -centers in the crystal, with an absorption band peaking at 250 nm and increasing in intensity with increasing dose across the entire range of doses studied. Increasing the irradiation dose leads to interactions between F - centers and the formation of more complex complexes, such as F2 - and F2⁺ - centers. The increase in the intensity of these bands, especially those of the R - and N- centers, at doses above 107 R indicates defect aggregation and the formation of stable color centers, which are the basis for the formation of nanoparticles in the crystal structure

Synthesis, Structural and Spectroscopic Characterization of [MnCl4](L1.H)2 Complex Derived from Manganese(II) Chloride and Novocaine Hydrochloride
type: item
description: This study reports the synthesis and characterization of a manganese(II) complex with protonated novocaine. The complex was prepared by reacting MnCl₂ (0.005 mol) and novocaine hydrochloride (0.01 mol) in aqueous solution under magnetic stirring at 800 rpm for 1.5 hours, followed by slow evaporation for 21 days, yielding crystalline [MnCl4](L1·H)2. X-ray diffraction revealed a monoclinic system (I2/a) with Mn²⁺ coordinated by four chloride ions in a distorted tetrahedral geometry. IR spectroscopy confirmed N–H, C–H, C=O, and Mn–Cl vibrational modes, while UV-Vis analysis showed d–d transitions (λ_max = 508 nm) and ligand-centered π→π*, n→π* absorptions. SEMEDS mapping validated elemental composition and coordination effects on ligand microstructure. Thermal analysis showed two main decomposition stages between 183– 215 °C and 245–424 °C, with mass loss indicating improved thermal stability. XRD patterns and diffractograms confirmed the individuality of the complex compared to the free ligand. The reproducible spectroscopic, crystallographic, and morphological results suggest the complex's potential for further studies in coordination chemistry and material science.
