On the First Curve in the FučiK Spectrum with Weights for a Mixed p-Laplacian
International Journal of Mathematics and Mathematical Sciences, 2007 We show the existence of a first curve in the Fučik spectrum with weights for the p-Laplacian under mixed boundary conditions. We also study the asymptotic behavior of this first curve.

On Fučik spectra for third order equations
Mathematical Modelling and Analysis, 2007 We construct the Fučik spectrum for some third order nonlinear boundary value problems. This spectrum differs essentially from the known Fučik spectra.

On the Fredholm Alternative for the Fučík Spectrum
Abstract and Applied Analysis, 2010 We consider resonance problems for the one-dimensional p-Laplacian assuming Dirichlet boundary conditions. In particular, we consider resonance problems associated with the first three curves of the Fučík Spectrum.

Evaluation of carbonification of coals using a portable Raman spectrometer
Journal of Raman Spectroscopy, Volume 54, Issue 11, Page 1220-1232, November 2023., 2023 This study illustrates that it is possible to discriminate among the coals of different degrees of maturation of the carbonaceous matter and other types of carbonaceous matter using the data acquired with a portable Raman spectrometer using spectroscopic parameters: D and G band widths and wavenumber positions.

Food Bioengineering, Volume 2, Issue 2, Page 89-104, June 2023., 2023 A novel Escherichia coli K12 derivative was used as a chassis for 2′‐FL biosynthesis. Inactivation of transcriptional regulator McbR can improve 2′‐FL production. Double mutation F40S/Q237S of FutC‐J166 increased 2′‐FL titer by 1.55‐fold. Abstract The most abundant human milk oligosaccharide 2′‐fucosyllactose (2′‐FL) is a valuable component that has ...

Microbial Biotechnology, Volume 15, Issue 12, Page 2970-2981, December 2022., 2022 An engineered Escherichia coli was developed for high‐titer FL biosynthesis by introducing multi‐level metabolic engineering strategies. Combined with the optimization of metabolic pathways and the performance improvement of rate‐limiting enzymes, 64.62 g/L of 2 '‐FL and 40.68 g/L of 3‐FL were finally obtained in the 3‐L bioreactors.

On some fučík type problem with cubic nonlinearity
Mathematical Modelling and Analysis, 2011 We study the second order Fučík type problem with cubic nonlinearity and construct the Fučík spectrum for this problem. The spectrum obtained under normalization condition (otherwise problem may have continuous spectra) structurally is similar to Fučík ...

On Fučík type spectrum for problem with integral nonlocal boundary condition
Nonlinear Analysis, 2019 The Fučík equation x' '= -μ x+λ x- with two types of nonlocal boundary value conditions are considered. The Fučík type spectrum for both problems are constructed. The visualization of the spectrum for some values of parameter γ is provided.
