A partial inverse problem for non-self-adjoint Sturm–Liouville operators with a constant delay
(De Gruyter, 2023)In this paper, we study a partial inverse spectral problem for non-self-adjoint Sturm–Liouville operators with a constant delay and show that subspectra of two boundary value problems with one common boundary condition are ... -
Antimicrobial synergism and antibiofilm activities of Pelargonium graveolens, Rosemary officinalis, and Mentha piperita essential oils against extreme drug-resistant Acinetobacter baumannii clinical isolates
(De Gruyter, March 2022)Abstract: Rosemary officinalis L., Pelargonium graveolens L., and Mentha piperita L., essential oils are used by complementary medicine specialists simultaneously with traditional antibiotics for treatment purposes. The ... -
Approximation of the image of the $L_p$ ball under Hilbert-Schmidt integral operator
(De Gruyter, 14.04.2023)In this paper an approximation of the image of the closed ball of the space $L_p$ $(p>1)$ centered at the origin with radius $r$ under Hilbert-Schmidt integral operator $F( \cdot ):L_p\rightarrow L_q$, $\frac{1}{p}+\frac{1}{q}=1,$ ... -

Assessment of epigenetic changes and oxidative DNA damage in rat pups exposed to polychlorinated biphenyls and the protective effect of curcumin in the prenatal period
(De Gruyter, 2019)Polychlorinated biphenyls (PCBs) are persistent organic chemicals that exert neurotoxic and endocrine disrupting effects. The aims of this study were to examine the effects of prenatal Aroclor 1254 (PCBs mixture) exposure ... -
Expression levels of BAP1, OGT, and YY1 genes in patients with eyelid tumors
(De Gruyter, 2021)Objectives: The aim of this study was to investigate BAP1, OGT and YY1 genes and protein levels in 12 samples (8 males, 4 females) of eyelid tumor tissue with basal cell carcinoma (BCC) and 12 normal control subjects ... -

Fatigue Life and Stress Analysis of the Crankshaft of a Single Cylinder Diesel Engine under Variable Forces and Speeds
(De Gruyter, 2021)In this paper, a single cylinder crankshaft manufactured with C45 steel was used to investigate variation in stress, deformation, and fatigue life and safety factor at critical locations of the crankshaft. For this ... -
Joint performance of medium carbon steelaustenitic stainless steel double-sided TIG welds
(De Gruyter, 2023)AISI 1040 and AISI 304 steel plates of 10 mm were joined without pretreatment by double-sided TIG arc welding (DSAW). Joints were manufactured by using welding currents of 420, 440, and 460 A. The microstructural variations ... -
Multiplicative (generalized)-reverse derivations in rings and Banach algebras
(De Gruyter, 2023)In this work, the subject of ideal in a semiprime ring with multiplicative (generalized)- reverse derivations studied is included. We give new essential results for researchers in this field and generalize some results ... -
MXenes and their composites as corrosion prevention
(De Gruyter, 2023)MXene, an advanced metal-based 2D ceramic material family, has had a sig- nificant impact in the field of corrosion prevention due to its unique physicochemical properties. Due to the need for further advancement and ... -
Polymeric nanoparticles and their composites in corrosion inhibition
(De Gruyter, 2023)Metal hardware is inherently prone to corrosion. Substantial research has been undertaken to explore to supersede this challenge. Initially, paints, pigments and organic coatings were utilized to circumvent metal corrosion. ... -
Spectra and fine spectra of the generalized upper difference operator with triple repetition ∆_3^ab on the Hahn sequence space
(De Gruyter, 2022)The goal of this paper is to obtain the spectra and ne spectra of the matrix D_3âb on the Hahn space. Also, we explore some ideas of how to study the problem for a general form of the matrix, namely, the matrix D_3âb where ... -
