Becomings in J. M. Coetzee's Waiting for the Barbarians and José Saramago's Blindness
(The Pennsylvania State University, 2010)
Highly variable upper and abyssal overturning cells in the South Atlantic
(American Association for the Advancement of Science, 2020-08-05)
The Meridional Overturning Circulation (MOC) is a primary mechanism driving oceanic heat redistribution on Earth, thereby affecting Earth's climate and weather. However, the full-depth structure and variability of the MOC ...
Coexistence and extinction in a competitive exclusion Leslie/Gower model with harvesting and stocking
(Taylor & Francis Online, 2009)
The principle of competitive exclusion states that when the competition between species is sufficiently strong, only the dominant species survives. In this paper, we examine the strategies of using stocking and harvesting ...
Folding and unfolding in periodic difference equations
(Elseiver, 2014)
Given a p-periodic difference equation xn+1 = fn mod p(xn), where each fj is a continuous interval map, j = 0, 1, . . . , p − 1, we discuss the notion of folding and unfolding related to this type of non-autonomous equations. ...
The Beverton–Holt model with periodic and conditional harvesting
(Taylor & Francis Online, 2009)
In this theoretical study, we investigate the effect of different harvesting strategies on the discrete Beverton–Holt model in a deterministic environment. In particular, we make a comparison between the constant, periodic ...
Biophysical model of coral population connectivity in the Arabian/Persian Gulf
(Elsevier, 2020)
The coral reef ecosystems of the Arabian/Persian Gulf (the Gulf ) are facing profound pressure from climate change (extreme temperatures) and anthropogenic (land-use and population-related) stressors. Increasing degradation ...
Scale-Up of Self-Regenerating Semi-Batch Adsorption Cycles through Concurrent Adsorption and Reduction of Cr(VI) on Sheep Wool
(MDPI, 2020)
A previous publication by our group reported that adsorption of Cr(VI) on sheep wool reached 99% when allowed a long residence time, with concurrent reduction to Cr(III). In this study, the process was scaled up by optimizing ...
Fluorescent aminal linked porous organic polymer for reversible iodine capture and sensing
(Nature, 2020)
A novel triazene-anthracene-based fuorescent aminal linked porous organic polymer (TALPOP) was prepared via metal free-Schif base polycondensation reaction of 9,10-bis-(4,6-diamino-S-triazin2-yl)anthracene and 2-furaldehyde. ...
Baal and Thoth: Unwelcome Apparitions in J. M. Coetzee’s The Master of Petersburg and Disgrace
(Johns Hopkins University Press, 2011)
The solution of a recursive sequence arising from a combinatorial problem in botanical epidemiology
(Taylor & Francis, 2013)
One of the central problems in botanical epidemiology is whether disease spreads within crops in a regular pattern or follows a random process. In this paper, we consider a row of n plants in which m are infected. We then ...
