Standing stocks and body size of deep-sea macrofauna: Predicting the baseline of 2010 Deepwater Horizon oil spill in the northern Gulf of Mexico
(
Elsevier
, 2012 , Article)
A composite database encompassing 6 benthic surveys from years 1983 to 2003 was constructed to evaluate the distribution of macrofaunal biomass in the deep Gulf of Mexico (GoM) prior to the Deepwater Horizon oil spill. ...
Infinite-dimensional LQ optimal control of a dimethyl ether (DME) catalytic distillation column
(
Elsevier
, 2012 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator in order to control the concentration profiles along a catalytic distillation column, which is modelled by a set of coupled hyperbolic partial ...
Extracellular matrix (ECM)
(
Springer Netherlands
, 2012 , Book chapter)
Summary: The region of space at the periphery of cyanobacterial cells is the interface between the environment and intracellular processes. This metaspace may include a structure appressed to the outer wall and membrane, ...
Isolation of entomopathogenic Bacillus from a biodynamic olive farm and their pathogenicity to lepidopteran and coleopteran insect pests
(
Elsevier Ltd
, 2012 , Article)
The occurrence of Bacillus entomopathogenic bacteria on a Tunisian biodynamic farm was determined by examining 75 samples from olive tree (Olea europaea L.) habitats. A total of 40 Bacillus isolates were characterized ...
Libya's Arab spring: The long road from revolution to democracy
(
SAGE
, 2012 , Article)
This article presents a critical account of Libya's incipient democratization, contextualizing it within the Arab Spring élan. This first line of inquiry is twofold: it critically assesses the meaning of democratization ...
Edge Maximal C2k+1-edge Disjoint Free Graphs
(
University of Zielona Gora
, 2012 , Article)
For two positive integers r and s, G(n;r,s) denotes to the class of graphs on n vertices containing no r of s-edge disjoint cycles and f(n;r,s) = max{E(G):G ∈ G(n;r,s)}. In this paper, for integers r ≥ 2 and k ≥ 1, we ...
Adsorption of 2, 4-dichlorophenoxyacetic acid onto date seeds activated carbon: Equilibrium, kinetic and thermodynamic studies
(2012 , Article)
Adsorption isotherm and kinetics of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide on activated carbon prepared from Barhi date seeds were determined from batch tests. The effects of contact time, initial herbicide ...
Dynamics of charge evolution in glass capillaries for 230-keV Xe23 + ions
(
American Physical Society
, 2012 , Article)
We have measured the transmission of 230-keV (10-keV/q) Xe23+ ions through insulating tapered glass capillaries of microscopic dimensions. The dynamics of charging and discharging processes have been investigated, evidencing ...
Batch study for herbicide bentazon adsorption onto palm oil fronds activated carbon
(2012 , Article)
The adsorption of herbicide bentazon from aqueous solution onto activated carbon derived from palm oil fronds (PFAC) was investigated through batch study. The effects of both; initial concentration of the bentazon (ranging ...
Histopathological effects and determination of the putative receptor of Bacillus thuringiensis Cry1Da toxin in Spodoptera littoralis midgut
(
Elsevier
, 2012 , Article)
Bacillus thuringiensis subsp. aizawai strain HD133, known by its effectiveness against Spodoptera species, produces many insecticidal proteins including Cry1Ab, Cry1Ca and Cry1Da. In the present study, the insecticidal ...
