Preparation, Spectral Characterization and Antioxidant Activities of Aminothiophene-Containing Schiff Base and Co(II) and Pd(II) Complexes.

This research focused on synthesizing a Schiff base (L) and its Co(II) and Pd(II) complexes under appropriate conditions to contribute to enhancing antioxidant activity. The ligand was synthesized by reacting methyl 2-amino-4-ethyl-5-methylthiophene-3-carboxylate with 5-bromo-2-hydroxybenzaldehyde. Various analytical techniques were employed to characterize the ligand and its resulting complexes, including microanalysis, H and C NMR spectroscopy, FTIR, electronic spectra, mass spectrometry, magnetic susceptibility, molar conductance, and thermo-gravimetric analysis.

Effects of gradual deformation of identical and nonidentical, rotated and nonrotated U-shaped subwavelength resonators in few-layer metasurfaces.

Raising of negative-index medium has been going hand-by-hand with the exploration of quasiplanar subwavelength resonators. Now they are widely used in modern microwave, terahertz, and infrared devices, as well as in advanced physics research. Effects of stacking of the arrays of subwavelength resonators in one few-layer metasurface is connected with the key problems of modern electrical engineering, applied physics, and beyond.

Betanin ameliorates lipopolysaccharide-caused testis damage via multiple signal networks.

The present study first evaluated the effects of betanin on the changes in oxidative stress/antioxidant, inflammatory, ER stress/antiapoptotic responses and 8-OHdG parameters as well as TLR4 and NF-κB activity on LPS-induced testis damage.

Evaluation of nasogastric tube location using point-of-care ultrasonography in paediatric patients.

Background: Nasogastric tubes (NGTs) are used in children emergency departments (EDs) for gastric decompression, as well as for enteral nutrition and drug administration in hospitalised patients. Radiography is considered the gold standard for determining NGT location and may require repeat films until the tube is appropriately positioned. Point-of-care ultrasonography (POCUS) could potentially be useful in avoiding radiation in these children.

Enhancing the power quality of dual rotor wind turbines using improved fuzzy space vector modulation and super twisting sliding techniques.

In the field of control, many approaches have been used to control generators, where indirect vector control (IVC) is considered one of the most prominent of these approaches due to its many advantages. This approach has a fast response time (RT) and is quite easy to realize. However, its reliance on traditional controllers makes this approach less efficient and less effective if the system parameters change.

The relationship between body mass index and survival in patients with renal cell carcinoma treated with nivolumab.

Introduction: Immunotherapies have increased the therapeutic options for patients with metastatic renal cell carcinoma (mRCC), but the absence of prognostic indicators remains unresolved. We assessed the potential association of BMI with the overall survival (OS) of patients treated with nivolumab.

Methods: We performed a retrospective study of 126 patients with histologically confirmed mRCC who began systemic ICI therapy between January 2016 and April 2022 were included.

Genetic algorithm type 2 fuzzy logic controller of microgrid system with a fractional-order technique.

This paper presents a hybrid approach that combines a genetic algorithm (GA)-optimized type-2 fuzzy logic controller (T2FLC) with a fractional-order technique for enhanced control of a microgrid system. The T2FLC approach is employed to handle the inherent uncertainties in the microgrid due to fluctuating renewable energy inputs and varying loads. The GA optimizes the parameters of the designed FO-T2FLC approach, ensuring optimal performance under different operational conditions.

Solving the problem of power ripples for a multi-rotor wind turbine system using fractional-order third-order sliding mode algorithms.

Power quality is one of the most prominent challenges hindering the spread and use of direct power control (DPC) in the field of control, especially for induction generator (IG) control. The lower power quality in the case of using the DPC approach is due to the use of hysteresis comparators. This work proposes a new controller to overcome the drawbacks of the DPC approach, such as low robustness and high total harmonic distortion (THD) value of current for IG present in multi-rotor wind turbine (MRWT) based power system.
