Performance of Micelle-Clay Filters for Removing Pollutants and Bacteria from Tertiary Treated Wastewater
(2012-02)Filters filled with a micelle-clay complex mixed with sand were employed to investigate their purification capability of tertiary treated wastewater with loose UF-membranes. The UF membrane was hollow fiber with a molecular ... -
Performance of Olive Waste Ash Concrete Exposed to Thermal Cycling
(2010-05)This paper explores the influence of olive waste ash (OWA) on the performance of concrete to thermal cycling. The performance of concrete to thermal cycling was evaluated by measuring the compressive strength, electrical ... -
Performance of RC Columns Strengthened with Fabric-Reinforced Cementitious Matrix (FRCM)
(2021-05)A recently emerging technique to strengthen existing concrete structures using Fiber-Reinforced Cementitious Matrix (FRCM) is introduced to retrofit structural members. FRCM is an inorganic matrix that consists of textile ... -
Performance of Structures Exposed to Extreme High Temperature - An Overview
(2013-09)Strength, durability and stability are the main criteria for material selection and design in the construction industry. Consequently, development and enhancement of construction materials is always an active and attractive ... -
Periodic Orbits in Periodic Discrete Dynamics
(Elsevier, 2008)We study the combinatorial structure of periodic orbits of nonautonomous difference equations 𝒳ₙ₊₁ = 𝒇ₙ(𝒳ₙ) in a periodically fluctuating environment. We define the Ӷ-set to be the set of minimal periods that are not ... -
Personalizing Group Instruction Using Knowledge Space Theory and Clustering Techniques
(2016-05)In the competitive market today, availability of appropriate skills and competencies that are aligned with an organization's objectives and that contribute to the organization's long-term success and survival is not always ... -
Personnel contributions to UN and non-UN peacekeeping missions A public goods approach
(2015)Based on spatial panel regressions for 1990-2012, this article draws publicness differences between peacekeeping personnel contributions to UN and non-UN peacekeeping operations. The analysis shows that UN missions are ... -
pH and ultrasound dual-responsive drug delivery system based on PEG–folate-functionalized Iron-based metal–organic framework for targeted doxorubicin delivery
(Elsevier, 2021)In recent years, the use of metal–organic frameworks (MOFs) as drug nanocarriers has gained attention because of their extraordinary physical and chemical properties. In this work, dual-responsive iron-based MOFs were ... -
pH-Responsive Nanocarriers in Cancer Therapy
(MDPI, 2022)A number of promising nano-sized particles (nanoparticles) have been developed to conquer the limitations of conventional chemotherapy. One of the most promising methods is stimuli-responsive nanoparticles because they ... -
Pharmaceutical wastewater treatment using graphene oxide derivatives
(2019-12)The rising problem of pharmaceutical contamination in different water bodies calls for a swift action in the treatment and removal of these emerging pollutants from water using advanced methods. Adsorption is employed as ... -
Pharmacognostic evaluation of Terminalia chebula standard extracts and finished products
(ResearchGate, 2019)The different commercial samples of Terminalia chebula (T. chebula) standard extracts and finished products were taken for elemental analysis studies and were evaluated by ICP-OES and compared with standard reference data. ... -
Phase transitions of nanoemulsions using ultrasound: Experimental observations
(Elsevier, 2012)The ultrasound-induced transformation of perfluorocarbon liquids to gases is of interest in the area of drug and gene delivery. In this study, three independent parameters (temperature, size, and perfluorocarbon species) ... -
Phase transitions of perfluorocarbon nanoemulsion induced with ultrasound: A mathematical model
(Elsevier, 2013)While ultrasound has been used in many medical and industrial applications, only recently has research been done on phase transformations induced by ultrasound. This paper presents a numerical model and the predicted results ... -
Phased Array Technique for Brain Source Localization
(2012-01)Magnetoencephalography (MEG) and Electroencephalography (EEG) are two popular non-invasive techniques that directly measure the magnetic/electric signals generated from the brain's electrical activity, unlike functional ... -
