A Note on Norland Summability of Fourier Series
( Qatar University , 1982 , Article)In this paper we consider point-wise summability in the Norlund sense of Fourier series by assuming H(n) . F(n) = o (Pn) as n--+ oo, where (H(x) = d.x g(t) dt, g(t) is continuous, non-increasing, H(x) is slowly varying, ... -
A Note on Parabolic Maximal Operators along Surfaces of Revolution via Extrapolation
( MDPI , 2022 , Article)Under weak conditions on the kernels, we obtain sharp Lp bounds for rough parabolic maximal integral operators over surfaces of revolution. By virtue of these bounds along with Yano’s extrapolation argument, we confirm the ... -
A Note On Pre-J-Group Rings
( Qatar University , 1991 , Article)Given an associative ring R satisfying a°'b = Ba" for any pair a and b of its elements, is being a positive integer, and a group G satisfying x""' = y"~1, we give a sufficient and necessary condition on the group ring GR ... -
A Note On Semi Generalized Closed Sets
( Qatar University , 1994 , Article)In the present note authors obtain some characterizations and properties of semi generalized closed sets. -

Notice of Retraction: Electromagnetic Radiation Due to Cellular, Wi-Fi and Bluetooth Technologies: How Safe Are We?
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Other)The electromagnetic radiation (EMR) emitted out of wireless communication modules in various IoT devices (especially used for healthcare applications due to their close proximity to the body) have been identified by ... -
Noun quantification in English and modern standard Arabic: a descriptive morphological comparison
( Qatar University , 1997 , Article)This paper examines quantifiers from a morphological point of view. It will focus on number in nouns, partitive constructions, collective nouns, numeral quantifiers, and non-numeral quantifiers in both English and Modern ... -
Novel 1,5-diphenyl-6-substituted 1H-pyrazolo[3,4-d]pyrimidin-4(5H)-ones induced apoptosis in RKO colon cancer cells
( Taylor and Francis Ltd , 2016 , Article)Novel 1,5-diphenyl-6-substituted-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-ones were synthesized and characterized. All compounds were screened for their anti-proliferative activities in five different cancer cell lines. The results ... -

Novel activation of peroxymonosulfate by biochar derived from rice husk toward oxidation of organic contaminants in wastewater
( Elsevier Ltd , 2020 , Article)In this study, novel activation of peroxymonosulfate (PMS) by biochar derived from rice husk (generally considered useless agricultural wastes in Vietnam) toward organic pollutants from wastewater was investigated. The ... -
Novel Actuator Fault Diagnosis Framework for Multizone HVAC Systems Using 2-D Convolutional Neural Networks
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Heating, ventilation, and air conditioning (HVAC) systems are used to condition the indoor environment in buildings. They can be subjected to malfunctioning since they are the most extensively operated buildings' components ... -
Novel Adsorbents For The Removal Of Oil From Produced Water
(2019 , Master Thesis)Produced water is water that is brought up to the surface of the well during oil and gas operations. Almost all oil and gas wells generate huge amounts of produced water as part of the production process. These large volumes ... -
A novel agent-based framework for evaluating pedestrian safety at unsignalized mid-block crosswalks
( Elsevier Ltd , 2021 , Article)A critical safety problem in road networks is the conflicts on unsignalized crosswalks. Thus, a proactive approach to assess pedestrian safety performance is required. Simulating the microscopic road user behavior in a ... -
A novel algorithm for molecular synthesis using enhanced property operators
( Elsevier Ltd , 2008 , Article)Traditionally process design and molecular design have been treated as two separate problems, with little or no feedback between the two approaches. Introduction of the property integration framework has allowed for ... -
Novel aluminum oxide-impregnated carbon nanotube membrane for the removal of cadmium from aqueous solution
( MDPI AG , 2017 , Article)An aluminum oxide-impregnated carbon nanotube (CNT-Al2O3) membrane was developed via a novel approach and used in the removal of toxic metal cadmium ions, Cd(II). The membrane did not require any binder to hold the carbon ... -
Novel analysis of glycan structures: Nanoscale approach
( Avestia Publishing , 2016 , Conference Paper)Glycans are complex saccharide moieties covering all cell surfaces - presented on different biomolecules. Almost 75% of all proteins are glycosylated, and these glycans can form thousands of different structures.[1] Moreover, ... -
Novel and robust machine learning approach for estimating the fouling factor in heat exchangers
( Elsevier , 2022 , Article)The fouling factor (Rf) is an operating index for measuring an undesirable effect of solids’ deposition on the heat transfer ability of heat exchangers. Accurate prediction of the fouling factor helps appropriate scheduling ... -
Novel approach in treating industrial wastewater using metal-organic framework nanoparticles impregnated with biosurfactants.
(2024 , Dissertation)Arabian Gulf countries including Qatar are amongst the main oil and gas (O&G) producers globally. A huge amount of water is used during the upstream and downstream processes of oil and gas refiners. As a result, a large ... -
A novel approach of encapsulating curcumin and succinylated derivative in mannosylated-chitosan nanoparticles
( Elsevier , 2022 , Article)Curcumin (CUR) manifests anti-colon cancer activity but suffers from low solubility, bioavailability, and instability, rendering it not as effective as its chemotherapeutic cousins. Here, we conjugate CUR to succinic ...
