Abstract In power generation and industries where CO2 emissions are unavoidable, carbon capture, utilisation, and storage is an important tool to offset climate change. Many carbon capture agents are blends of aqueous am...

In this work, shells are mathematically constructed by applying the cut and paste procedure to D-dimensional spherically symmetric geometries. The weak energy condition for the matter on the shells is briefly analyzed. T...

This study investigated the effect of nano-SiO2 (0.125, 0.25, and 0.5 wt %) and micro-SiO2 (3, 6, and 9 wt %) additions on the corrosion resistance of aluminum (Al) fabricated by powder metallurgy (PM). The Al powder a...

Smear layer removal in root canal treatment is required to aid the diffusion of intracanal medicament and help sealer penetrate into dentinal tubules. The need for irrigants is important to facilitate smear layer removal...

This study deals with problematic features of Czech-Hungarian translation, focusing primarily on issues regarding translations of contemporary Hungarian literature, not only from the aesthetic point of view but from a li...

Cu2ZnSnS4 (CZTS) is one of the promising materials for absorber layers of new-generation thin film solar cells. Various synthetic routes of materials preparation and structural characterization have been explored so far....

Background and purpose: Artificial intelligence-based contouring tools enable assessment of radiation doses to cardiac substructures beyond mean heart dose. This study examined inter-solution variations in raw contours a...

Successful phasing of synchrotron through-the-substrate microdiffraction data by δ-recycling direct-methods largely depends on the number of missing intensities caused by the limited sample rotation range [J. Rius, Dire...

In the current study, the effect of lethal concentrations of drug solutions and chemicals against pupae of Culex pipiens molestus mosquitoes was investigated after 24 hours and up to 3 days of the experiment using differ...

Narcissus is widely used as a cut flower worldwide due to its attractive color, aesthetic appearance, and pleasant fragrance. However, its vase life is relatively short. Therefore, developing appropriate treatments to im...

Aims: (i) To determine the aflatoxin B1 (AFB1) adsorption and desorption dynamics in the presence of Lactobacillus rhamnosus RC007 under simulated transit of AFB1 at each gastrointestinal tract (GIT—saliva, stomach and...

Nonlinear response conception in rotating machinery, particularly in systems with squeeze film dampers (SFDs), pose significant challenges for established time-domain numerical methods due to bifurcations and critical po...

Vinte plantas de abacaxi "Pérola" foram cultivadas em vasos de plástico de 10 L, em casa de vegetação, com o objetivo de caracterizar os sintomas visuais de deficiência de B nas plantas e nos frutos. Os vasos contin...

Abstract In this research, the optical activity of glucose solution had been studied through the studying of influence of this solution in rotation of polarization plane of laser He-Ne light, the different concentrations...

Due to the impact of crude oil prices on refinery revenues, the petroleum industry has switched to processing lowcost crude oils. They are blended with high-quality crude oils to feed the crude distillation units (CDUs) ...

Using molecular dynamics experiments, we analyze equilibrium and dynamical characteristics related to the solvation of excess protons in water-acetone mixtures. Our approach is based on the implementation of an extended ...

Inverse sensing is an important research direction to provide new perspectives for optical sensing. For inverse sensing, the primary challenge is that scattered photon has a complicated profile, which is hard to derive a...

Abstract Fuel consumption is one of the main concerns for heavy-duty trucks. Predictive cruise control (PCC) provides an intriguing opportunity to reduce fuel consumption by using the upcoming road information. In this s...

Based on van't Hoff and Gibbs equations, thermodynamic functions Gibbs energy, enthalpy, and entropy of solution, mixing and solvation of ibuprofen in water at pH 1.2 and 6.8, were evaluated from solubility values determ...

I use a new technique to derive a closed-form solution for the price of a European call option on an asset with stochastic volatility. The model allows arbitrary correlation between volatility and spotasset returns. I in...

Kinetic data for the radicals H⋅ and ⋅OH in aqueous solution,and the corresponding radical anions, ⋅O− and eaq−, have been critically pulse radiolysis, flash photolysis and other methods. Rate constants for ove...

The aim of this work is evaluate the influence of extractives parameters on tannin content of solutions obtained from leaves of P. guajava and the antimicrobial activity of the best extract solution. The type of extracti...

Evolutionary algorithms (EAs) are often well-suited for optimization problems involving several, often conflicting objectives. Since 1985, various evolutionary approaches to multiobjective optimization have been develope...

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...
