In 2022, the International Classification of Diseases (ICD-11) and an update Diagnostic Statistical Manual Mental Disorders (DSM 5 TR) were released for implementation worldwide now include new Prolonged Grief Disorder (PGD). The newest definition PGD is based on robust clinical research from Global North yet until has not been tested global applicability. current study assesses ICD-11 criteria in a large international sample 1393 bereaved adults. majority was included USΑ. Additionally, we...
Abstract In this study, heavy metals pollutions in waters, soils and vegetables were investigated from farms, near oil refinery south of Tehran city, Iran (Shahre Ray). The most important Iranian are vanadium, cobalt, nickel, arsenic mercury (V, Co, Ni, As, Hg). region, the concentration soils, well waters leafy edible evaluated ten different points farms. Geographic information systems (GIS) used to estimate levels at unmeasured locations. After sample preparation, concentrations...
This study was designed to examine the chemical composition of essential oil and in vitro antioxidant antimicrobial activity methanol extracts Eucalyptus largiflorens F. Muell. The hydrodistilled leaves E. analyzed by gas chromatography chromatography/mass spectrometry. main constituents were found be 1,8-cineole (23.1%), cryptone (15.1%), 4-allyloxyimino-2-carene (11.2%), 4-terpineol (9.6%). showed strong antibacterial against studied microorganisms, except for P. aeruginosa, while polar...
The solubility of hydrogen sulfide in N-methylacetamide and N,N-dimethylacetamide were experimentally measured. Gas concentrations systematically measured by the isochoric saturation method at temperatures from (303.15 to 363.15) K pressures vapor pressure solvent up about 2.2 MPa. Results show that H2S is more than N-methylacetamide. experimental data correlated using (1) Krichevsky–Ilinskaya equation (2) a generic Redlich–Kwong (RK) cubic state. Using data, partial molar thermodynamic...
An efficient analytical method called ionic-liquid-based ultrasound-assisted in situ solvent formation microextraction followed by high-performance liquid chromatography was developed for the determination of atenolol human plasma. A hydrophobic ionic (1-butyl-3-methylimidazolium hexafluorophosphate) formed addition a hydrophilic tetrafluoroborate) to sample solution containing an ion-pairing agent during microextraction. The analyte extracted into phase while dispersed throughout utilizing...
A simple, efficient and virtually solventless headspace liquid-phase microextraction (HS-LPME) technique, combined with gas chromatography−mass spectrometry (GC−MS), was developed for the analysis of sorbic acid (SA) benzoic (BA) in soft drinks environmental water samples. microdrop organic solvent suspended from tip a microsyringe needle over stirred sample solution, containing analytes desired time. The then retracted into directly injected GC−MS, without any further pretreatment....
A simple and sensitive methodology based on liquid-phase microextraction (LPME) followed by GC-MS, was developed for the determination of trihalomethanes (THMs) in drinking water. microdrop organic solvent floated surface aqueous sample it agitated a desired time. Then, vial cooled inserting into an ice bath 4 min. The solidified transferred suitable immediately melted. extract directly injected GC. Microextraction efficiency factors were investigated optimized: 7 muL 1-undecanol exposed 15...
A simple and efficient method, ionic liquid-based dispersive liquid-liquid microextraction combined with high-performance liquid chromatography-ultraviolet detection (HPLC-UV), has been applied for the extraction determination of some antioxidants (Irganox 1010, Irganox 1076 Irgafos 168) in water samples. The efficiency factors were investigated optimized: 1-hexyl-3-methylimidazolium hexafluorophosphate [C(6)MIM][PF(6)] (0.06 g) as extracting solvent, methanol (0.5 mL) disperser solvent...
Purpose – The purpose of this paper is to describe the behavior 2-mercaptobenzothiazole (MBT) on corrosion 316 stainless steel (SS) in acidic media and mechanism its action. Design/methodology/approach inhibitive effect MBT towards SS acid solution studied by means weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy. inhibitor concentration temperature against action investigated. Adsorption isotherm adsorption are also discussed. Findings acts as for type...

The solubility of carbonyl sulfide (COS) in two low vapor pressure organic solvents, namely, sulfolane (SFL) and γ-butyrolactone (GBL), was measured by experimental trial. gas determined using an isochoric saturation method under a static situation at temperatures from 303.15 to 353.15 K pressures the solvent up about 1.2 MPa. absorption data were correlated Peng–Robinson–Stryjek–Vera (PRSV) cubic equation state (EoS) as φ–φ approach Krichevsky–Ilinskaya (KI) model with combination PRSV EoS...
Natural gas (NG) is one of the widely used domestic fuels in most countries, and because economical environmental advantages, its consumption continuously increasing. As a result, complex piping systems are being installed to transport distribute for end users. Pipelines carrying NG significant source hazard their adjacent society. The risk this could be high especially distribution network urban areas where population density high. common causes accident are: third party interference,...
