Abstract This study examines the influence of divisor selection on the efficacy of advanced analytical spectrophotometric methods that integrate artificial intelligence (AI), green-chemistry principles, and white-analyti...

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 ...

Pyrrolizidine alkaloids （PAs） are a class of naturally occurring toxic compounds widely distributed in plants， primarily transmitted and bioaccumulated through the food chain. They have been detected in various foo...

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...

Abstract Air pollution is a major environmental and public health challenge in Greater Cairo due to rapid urbanization, intense traffic activity, and recurrent regional dust intrusions. This study presents a data driven ...

The article’s aim is to evaluate the utility of using the Cyber Threat Intelligence (CTI) approach in analysing information and influence operations. The study was carried out by a comparative method based on the techn...

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 ...

Abstract Selective Catalytic Reduction (SCR) helps to reduce Nitrogen Oxide (NO) emissions from diesel engines using catalytic materials made of thermally stable non-precious metals. A dual support SCR catalyst using iro...

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 In the present study, we examine how optical solitons behave in a synthetic nonlocal nonlinear medium. An analytical investigation is conducted into the nonlinear dynamical model that represents the propagation ...

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...
