Abstract Owing to the residual toxicity and adverse health effects of chemical preservatives, there is an increasing demand for using natural preservatives in food. Although many natural extracts have been evaluated, res...

The knowledge and the ability to describe the phase equilibrium behavior of systems composed of transesterification products are very important in the optimization of biodiesel production and purification process. In thi...

Abstract In this work, a new concept of planar resonator technique for measurement of liquid mixture permittivity is proposed, designed, and implemented using a Sixteen-Mode Substrate Integrated Waveguide (SMSIW) technol...

Ethylhexyl triazone (EHT) is a sunscreen agent widely used in the formulation of skin care products, whose physicochemical properties have not been thoroughly studied. In this work the Extended Hildebrand Solubility Ap...

The objective of the present study was to stabilize doxorubicin hydrochloride in sugar-phosphate amorphous mixtures at ambient temperature by drying it with vacuum foam drying. Finished products were evaluated for foam...

With the increasing relevance of energy transition, synthetic fuels have arisen as an alternative to storage green energy. In the processing of this fuels, carbon monoxide is widely used. Understanding the behaviour of t...

Raman spectroscopy in combination with partial least-squares (PLS) regression method was developed for sulphamethoxazole (SMZ) and trimethoprim (TMP) simultaneous determination in powder mixtures. The calibration set was...

The solubility of pioglitazone hydrochloride in polyethylene glycol 600-ethanol-water mixtures at 25 °C was determined using flask shake method. The generated data extended the solubility database for further computatio...

Propranolol-HCl (PPN-HCl) is a non selective β-adrenergic blocker widely used in therapeutics. Nevertheless, their physicochemical properties in aqueous media have not been adequately studied. In this context, by usin...

The solubility of sulfanilamide (SA) in propylene glycol + water cosolvent mixtures was determined at temperatures from 293.15 to 313.15 K. The thermodynamic functions: Gibbs energy, enthalpy, and entropy of solution and...

The results of a predictive analysis of the mock-up of a reactor containment building, based on computer numerical simulation, are presented in this paper and compared with the results obtained in the context of the VeRC...

Abstract Background Epidemiological associations between multiple metals exposure and hypertension or blood pressure remain limited and inconclusive, especially for essential metals. This investigation intended to examin...

Abstract This work developed an enhanced model to examine the High-Strength Fiber-Reinforced Concrete (HSFRC) that is replaced with 10% metakaolin as a sustainable cement replacement and four types of fibers at different...

The paper presents the quantitative measurement and variability of six non-traditional grain quality indicators of 10 cultivars of common winter wheat harvested in 2021-2022, obtained during tests using the Chopin+ proto...

Non-lethal biological techniques such as blood biomarkers have gained attention due to their value as early signals of anthropic effects of contamination representing significant tools to evaluate ecosystems health. We e...

Abstract Background Polycyclic aromatic hydrocarbons (PAHs) comprise a group of persistent carcinogenic pollutants whose transfer from air to soil via the atmospheric deposition represents a major chronic exposure pathwa...

Passive SONAR has attracted significant attention in covert operations, enabling vessel detection and classification through spectrogram analysis of received signals without active transmission. However, in realistic oce...

Abstract This study aims to evaluate biogenic amine levels of bez sucuks (BS) produced with different meat:fat ratios. For this, three BS groups were manufactured with meat:fat ratios of 90:10 (BS10), 80:20 (BS20), and 7...

The aim of this work was to evaluate the composting process of poultry manure mixed with other complementary organic wastes. Two mixtures (treatment 1 and 2) were prepared with corn bare cobs, sawdust, shavings and manur...

Fine-scale heterogeneity in soil nutrient availability can enhance plant growth, yet its effect across soil depth remains inadequately understood. Communities with increased species diversity showed varying growth strate...

The results of the researching of thermoelectric properties of samples, which are obtained by compressingmechanical mixtures of microdisperse powders PdTe and CdTe, are presented. It was found that the using ofcadmium fo...

Abstract The aim of this study was to evaluate the potential use of fatty acids, triacylglycerols, and cholesterol in the detection of adulterated milk fat. The fatty acid, triacylglycerol, and cholesterol profiles of th...

Cured-in-place pipe (CIPP) technology is widely used for pipeline rehabilitation, but curing emissions and leachates may introduce complex chemical mixtures into air and drinking water, raising environmental health conce...

Crystalline and electronic structures of SiO2/Al2O3 mixtures have been analyzed using X-ray diffraction (XRD) and ultra-soft X-ray emission spectroscopy (USXES). Comparison of ultrasoft X-ray emission AlLα-, SiLα- and ...
