This review article points out, through an overview, aspects that are related to the procedures established by green analytical chemistry, for the extraction of bioactive compounds in plants, through the use of assisted ...

Chlorella micro algae strains offer sustainable biomass feedstocks in biofuel production because of their resilience, diversity, high adaptability to environmental stresses, flexible cultivation alternatives and high bio...

In the last decades, the determination of trace elements in biological materials has emerged as an important area of study because of its relevance to human health and the environment. Inductively coupled plasma mass spe...

Education is a vital need for humans; however, high education costs often become a barrier for students, particularly those from underprivileged backgrounds. Although scholarships offer an alternative solution, scholarsh...

"The amount of multidimensional data published on the semantic web (SW) is constantly increasing, due to initiatives such as Open Data and Open Government Data, among other ones. Models, languages, and tools, that allow ...

Cadmium (Cd) is a toxic heavy metal found in tobacco, water, and food. Exposure to this metal can be harmful to health, causing kidney, bone, and respiratory problems, and even cancer. Furthermore, Cd exposure through ma...

Background: In calibration, analytical figures of merit (AFOMs) are statistical parameters of great importance for method validation. In recent decades, relevant contributions have been made to estimate AFOMs in many cal...

We obtain, using semianalytical transfer operator techniques, the Edwards thermodynamics of a one-dimensional model of blocks connected by harmonic springs and subjected to dry friction. The theory is able to reproduce t...

Abstract A selective and eco-friendly spectrophotometric approach was developed for the quantitative determination of entacapone (ENT) in the presence of its co-formulated drugs carbidopa (CAR) and levodopa (LEV) which e...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants of global concern due to their widespread occurrence, environmental persistence, and well-documented adverse effects on human health. In ...

Abstract Objective To describe the clinical experience with the B-Lynch technique in the management of postpartum hemorrhage as well as the factors related to the indication of the technique and to present the success ...

Background: Carbon footprint quantification currently stands as the most accepted model for assessing the ecological impact of human activities.Selecting the most environmentally friendly treatment for pathologies arisin...

Abstract Colostrum is the first mammary secretion produced after parturition and represents a biologically active fluid essential for neonatal survival, immune maturation, and early growth. Despite its importance, breed-...

Cancer-associated fibroblasts (CAFs) are one of the main components of the tumor microenvironment (TME) of solid tumors. They have several functions, which all contribute to tumor growth and immune evasion. CAF presence ...

Classical spin liquids have been a very active subject of research in the last few years. A very rich variety of cases have been shown to exist, including short-range and algebraic spin liquids displaying dipolar correla...

Advanced analytical techniques such as Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are powerful tools for chemical analysis; however, they present several practical challenges, including high operating costs, t...

The present study reports the synthesis of a novel cadmium (II) chloride complex containing ethylenediamine (en) and adenine (Ade) as ligands. The synthesized complex was characterized by several analytical techniques, i...

Estimating epidemiological cutoff endpoints (ECVs/ECOFFS) may be hindered when there is overlap between MICs for strains that are genetically wild type (WT) and non-WT (harboring cyp51A mutations). We collected posaconaz...

Nonlinear wave dynamics play an essential role in understanding energy localization, pulse transmission, and stability events in a variety of physical systems. Inspired by its importance, we study a fourth-order nonlinea...

This study evaluates Tibet leucogranites as a potential raw material for high-purity quartz. We systematically investigate the petrography, geochemistry, and purification potential of leucogranites from the Ama Drime Mas...

A certainty factor (CF) rule-based technique is frequently used by traditional expert systems (TES) in the medical industry to compute several symptoms and identify the inference solutions. The primary concern for this T...

Background: As athletes develop, their motor patterns evolve from variable to adaptive neuromuscular control strategies, enabling precise execution of complex movements. Traditional linear biomechanical analyses of wrest...

Introduction: High-fidelity clinical simulation has implied a revolution in health science training. Despite its benefits, some drawbacks could hinder the learning process, especially the anxiety produced during such sce...

Selected aspects of methodological developments in socio-economic research are addressed from a conceptual perspective, with outlining the areas of transformations in methodology, and illustrating the feasibilities of it...
