Myriophyllum -like hierarchical TiN@Ni3N nanowire arrays for bifunctional water splitting catalysts
(
Royal Society of Chemistry
, 2016 , Article)
Inspired by Myriophyllum, a natural plant, we report an efficient electrochemical water splitting device based on hierarchical TiN@Ni3N nanowire arrays. The bifunctional TiN@Ni3N nanowire arrays serve as both hydrogen ...
Investigating chlorophyll and nitrogen levels of mangroves at Al-Khor, Qatar: an integrated chemical analysis and remote sensing approach. Environmental Monitoring and Assessment
(
Springer Verlag
, 2016 , Article)
Mangroves are unique ecosystems that dominate tropical and subtropical coastlines around the world. They provide shelter and nursery to wide variety of species such as fish and birds. Around 73 species of mangroves were ...
Caught basking in the winter sun: Preliminary data on winter thermoregulation in the Ethiopian hedgehog, Paraechinus aethiopicus, in Qatar
(
Academic Press
, 2016 , Article)
Biologists focus on thermoregulation of desert mammals in terms of how they minimize heat gain, and put less effort on how they maximize heat gain during the cooler months. Heat gain may contribute to significant energy ...
Ordered, highly zeolitized mesoporous aluminosilicates produced by a gradient acidic assembly growth strategy in a mixed template system
(
American Chemical Society
, 2016 , Article)
Tremendous efforts have been made in recent years to synthesize ordered mesoporous zeolite materials, because of the accelerating demands of industrial bulky molecule conversion. Here, we develop a novel gradient acidic ...
Using learning analytics to assess student learning in online courses
(
University of Wollongong
, 2016 , Article)
Learning analytics can be used to enhance student engagement and performance in online courses. Using learning analytics, instructors can collect and analyze data about students and improve the design and delivery of ...
Numerical Computation of the Conformal Map onto Lemniscatic Domains
(
Springer
, 2016 , Article)
We present a numerical method for the computation of the conformal map from unbounded multiply-connected domains onto lemniscatic domains. For ℓ -times connected domains, the method requires solving ℓ boundary integral ...
Impact of thinning on carbon storage of dead organic matter across larch and oak stands in South Korea
(
SISEF - Italian Society of Silviculture and Forest Ecology
, 2016 , Article)
Dead organic matter is important in carbon (C) sequestration because it accounts for a significant proportion of forest C storage. As thinning could alter the C storage of dead organic matter, this study aimed to assess ...
Mass problems and density
(
World Scientific Publishing Co. Pte Ltd
, 2016 , Article)
Recall that Ew is the lattice of Muchnik degrees of nonempty effectively compact sets in Euclidean space. We solve a long-standing open problem by proving that Ew is dense, i.e. satisfies {equation presented}. Our proof ...
Antioxidant and antihypertensive properties of phenolic-protein complexes in extracted protein fractions from Nigella damascena and Nigella arvensis
(
Elsevier
, 2016 , Article)
The study involved the investigation of the antioxidant and antihypertensive properties of the phenolic–protein complexes obtained from isolated protein fractions from Nigella damascena and Nigella arvensis. Protein fractions ...
Countering piracy through private security in the Horn of Africa: prospects and pitfalls
(
Taylor & Francis (Routledge)
, 2016 , Article)
Employing secondary research and semi-structured interviews, this article examines the use of private maritime security companies (PMSC) in providing maritime security services in the Horn of Africa. It consists of four ...
