On MorphoSyntactic Levantisms in Maltese
(Institut de recherches et d’études sur les mondes arabes et musulmans (IREMAM), 2019)Maltese is usually classified as a North African Arabic variety. Yet some researchers have remarked “some curious similarities with the Eastern dialects”. Investigations of these tend to concentrate upon the phonology and ... 
On phiDedekind rings and phiKrull rings
(University of Houston, 2005)The purpose of this paper is to introduce two new classes of rings that are closely related to the classes of Dedekind domains and Krull domains. Let H = {R  R is a commutative ring with 1 and Nil(R) is a divided prime ... 
On phiMori rings
(University of Houston, 2006)A commutative ring R is said to be a phiring if its nilradical Nil(R) is both prime and comparable with each principal ideal. The name is derived from the natural map phi from the total quotient ring T(R) to R localized ... 
On the dot product graph of a commutative ring II
(International Electronic Journal of Algebra, 2020)In 2015, the secondnamed author introduced the dot product graph associated to a commutative ring A. Let A be a commutative ring with nonzero identity, 1 ≤ n < ∞ be an integer, and R = A × A × · · · × A (n times). We ... 
On the periodic logistic equation
(Elsevier, 2006)We show that the 𝒑periodic logistic equation 𝒳ₙ₊₁ = μₙ mod 𝒑𝒳ₙ(1  𝒳ₙ) has cycles (periodic solutions) of minimal periods 1; 𝒑; 2𝒑; 3𝒑; …. Then we extend Singer’s theorem to periodic difference equations, and use ... 
On weakly 2absorbing ideals of commutative rings
(University of Houston, 2013)Let R be a commutative ring with identity 1 not equal to 0. In this paper, we introduce the concept of a weakly 2absorbing ideal. A proper ideal I of R is called a weakly 2absorbing ideal of R if whenever abc is not equal ... 
Option convergence rate with geometric random walks approximations
(Taylor & Frances Online, 2016)We describe a broad setting under which, for European options, if the underlying asset form a geometric random walk then, the error with respect to the Black–Scholes model converges to zero at a speed of 1/𝑛 for continuous ... 
Outcomes and Key Factors of Success for ISO 14001 Certification: Evidence from an Emerging Arab Gulf Country
(MDPI, 2019)The objectives of this research were: (1) To examine the outcomes and key factors of success (KFS) related to ISO 14001 certification, (2) to compare and contrast these in private organizations (PRIVOs) and public organizations ... 
Path Independence of Exotic Options and Convergence of Binomial Approximations
(Infopro Digital Risk (IP), 2019)The analysis of the convergence of tree methods for pricing barrier and lookback options has been the subject of numerous publications aiming at describing, quantifying, and improving the slow and oscillatory convergence ... 
Perceiving Emotions, Facilitating Thought, and Promoting Growth: Using Emotional Intelligence as an Effective Teaching Technique in the Freshman Composition Classroom
(Common Ground Publishing, 201606)One of the key issues in teaching writing to students in the Middle East and North Africa (MENA) region is that they come from diverse high school contexts. Some students have never been formally taught in English, and ... 
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 Ӷset to be the set of minimal periods that are not ... 
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 ICPOES and compared with standard reference data. ... 
The Photocatalytic Degradation of 2,3,7,8TetrachlorodibenzopDioxin in the Presence of Silver–Titanium Based Catalysts
(MDPI, 2020)Polychlorinated dibenzopdioxins (PCDD) are persistent toxic compounds that are ubiquitous in the environment. The photodegradation of 2,3,7,8tetrachlorodibenzopdioxin (TCDD) in the presence of silver titanium oxide ... 
PIRATA: A Sustained Observing System for Tropical Atlantic Climate Research and Forecasting
(American Geophysical Union (AGU), 2019)Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) is a multinational program initiated in 1997 in the tropical Atlantic to improve our understanding and ability to predict ocean‐atmosphere variability. ... 
Ramsey numbers of partial order graphs (comparability graphs) and implications in ring theory
(De Gruyter, 2020)For a partially ordered set(A, ≤), letGA be the simple, undirected graph with vertex set A such that two vertices a ≠ ∈ b A are adjacent if either a ≤ b or b a ≤ . We call GA the partial order graph or comparability graph ... 
Recent Advances in Femtosecond LaserInduced Surface Structuring for Oil–Water Separation
(MDPI, 2019)Femtosecond (FS) laserinduced surface structuring is a robust, maskless, noncontact, and singlestep process for producing micro and nanoscale structures on a material’s surface, which remarkably alters the optical, ... 
Refinancing the Rentier State: Welfare, Inequality, and Citizen Preferences toward Fiscal Reform in the Gulf Oil Monarchies
(City University of New York, 2019)Middle East oil producers are today pursuing profound transformations of their rentier economies, including through new taxes and reductions in state spending and welfare subsidies that have supported citizens for generations. ... 
The relative effects of isolated and combined structures input and structured output on the acquisition of the English causative forms
(De Gruyter, 2017)The present study explores the effects of structured input and structured output when delivered in isolation or in combination on the acquisition of the English causative. Research investigating the effects of processing ...
