Research ArticleOpen accessIn the abstractLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,065 accessesView PDFCite
Review ArticleOpen accessIn the abstractRole of HDL in Atherogenesis: Cholesterol and AtheroprotectionAnastasia Vladimirovna Poznyak, Vasily Nikolaevich Sukhorukov, Victor Yurievich Glanz et al.Atherosclerosis is a major global health burden, responsible for a significant proportion of cardiovascular morbidity and mortality worldwide. Its high prevalence and severe clinical consequences have made it a subject of extensive research. Despite considerable advances, the complexity of its pathogenesis continues to hinder the development of effective preventive strategies and therapeutic interventions. Current evidence implicates chronic inflammation, dysregulated lipid … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 3 Apr 2026 · 1,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Forensic Profiling of Primer-Derived Inorganic Gunshot Residues Using SEM-EDX SpectroscopyAhmed M. Bendary Salem, Aldo Barbaro, Bolaji OladipoGunshot Residue (GSR) analysis presents a significant challenge in forensic science due to the need to detect and identify minute traces of powders and initiating compositions formed during the chemical decomposition and deflagration processes within cartridge cases. This research is a qualitative comparative profiling study, designed to create a reference database of the most characteristic elemental markers for commonly used … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 6 Mar 2026 · 2,738 accessesView PDFCite
Literature ReviewOpen accessIn the abstractRemineralization Potential of Bioactive Composite Resins: A Systematic ReviewLuiza Maria Schneider, Maria Ritha Veiga Colognese, Poliana Maria de Faveri Cardoso et al.To evaluate the clinical performance and potential of giomer-based materials in promoting the remineralization of dental structures through a systematic review of the literature. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science databases up to March 2024. “giomer,” “S-PRG,” “bioactive restorative materials,” “remineralization,” and “dental caries.” Inclusion criteria comprised clinical studies involving human subjects, with … …Current Research in Dentistry, Vol. 17, Issue 1 · 29 Jan 2026 · 3,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,412 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA has Found the Most Distant Black HoleRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuScientists have uncovered a rare relic from the early universe: the farthest known supermassive black hole. This matter-eating beast is 800 million times the mass of our Sun, which is astonishingly large for its young age. Researchers report the find in the journal Nature. "This black hole grew far larger than we expected in only 690 million years after the … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Activated Carbon from Eggshell Membranes Prepared Using Sodium Acetate and Zinc Metal ActivationSumrit Mopoung, Kanjana JitchaijaroenkulThe eggshell membranes of ducks and hens were carbonized or activated with 4 wt% sodium acetate or zinc at 400-600°C. The carbonized or activated products were characterized by SEM-EDS, TEM, FTIR and XRD. It was found that the suitable activation temperature for eggshell membranes is 500°C with 30.03-35.26% yield. The activation performance of CH3COONa for eggshell membrane activated carbon production … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 2 Aug 2017 · 8,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractGreen Synthesis of Silver Nanoparticles using Mediterranean Cypress (Cupressus sempervirens) Leaf ExtractAlireza Ebrahiminezhad, Saeed Taghizadeh, Younes GhasemiSilver nanoparticles (AgNPs) retained vast applications in science and technology. Due to the vast application of these particles in various disciplines, there is an interest for synthesis of AgNPs in an environmentally friendly and economic manner. For the first time we were used Mediterranean cypress (Cupressus sempervirens) leaf aqueous extract for biosynthesis of AgNPs.

Research ArticleOpen accessIn the abstractInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractParticle Size Determination in Rice Bran Testing with Various Levels of Rice Husks Using Ultrasonic WavesUrip Rosani, Iman Hernaman, Rahmat Hidayat, Darmawan HidayatThe principle of ultrasonic waves in detecting materials is based on their physical properties.
