The United Nations(UN)’s call for a decade of“ecosystem restoration”was prompted by the need to address the extensive impact of anthropogenic activities on natural *** ecosystem restoration is increasingly necessary due to increasing habitat degredation in deep waters(>200 m depth).At these depths,which are far beyond those accessible by divers,only established and emerging robotic platforms such as remotely operated vehicles(ROVs),autonomous underwater vehicles(AUVs),landers,and crawlers can operate through manipulators and multiparametric sensor arrays(e.g.,optoacoustic imaging,omics,and environmental probes).The use of advanced technologies for deep-sea ecosystem restoration can provide:①high-resolution three-dimensional(3D)imaging and acoustic mapping of substrates and key taxa,②physical manipulation of substrates and key taxa,③real-time supervision of remote operations and long-term ecological monitoring,and④the potential to work ***,we describe how robotic platforms with in situ manipulation capabilities and payloads of innovative sensors could autonomously conduct active restoration and monitoring across large spatial *** expect that these devices will be particularly useful in deep-sea habitats,such as①reef-building cold-water corals,②soft-bottom bamboo corals,and③soft-bottom fishery resources that have already been damaged by offshore industries(i.e.,fishing and oil/gas).

Substituent, Temperature and Solvent Effects on the Keto-Enol EQUILIBRIUM in <i>β</i>-Ketoamides: A Nuclear Magnetic Resonance Study

引用

Open Journal of Physical Chemistry 2013年第4期3卷 138-149页

作者： sergio L. Laurella Manuel gonzález Sierra Jorge J. P. Furlong Patricia E. Allegretti Laboratorio LADECOR División Química Orgánica Departamento de Química Facultad de Ciencias Exactas Universidad Nacional de La Plata (UNLP) La Plata Argentina

Substituent, temperature and solvent effects on tautomeric equilibria in several β-ketoamides have been investigated by means of nuclear magnetic resonance spectroscopy (NMR). Keto-enol equilibrium predominates over the amide-imidol one. The relative stability of the individual tautomers and the corresponding equilibrium shifts are explained considering electronic and steric effects and tautomer stabilization via internal hydrogen bonds. In solution, these compounds exist mainly as ketoamide and Z-enolamide tautomers, both presenting intramolecular hydrogen bonds.

Advances in Manufacturing 2013年第3期1卷 198-210页

Encapsulation of different guestspecies such as molecules and ions inside carbon nanotubes （CNTs） has been reported in the literatures during the last 15 years and repre sents an exciting development of nanoengineering of novel materials and composites. The reported nanocomposite mate rials show the semiconducting properties with potential applications in nanosensors, nanounits and nanocircuits as well as advanced energy transfer and storage properties, and encompass manufacturing for novel nanowires, nanoelectronic devices with properties designed with optoelectronic, spin tronic and nanomagnetic qualities. This review reports on a wide range of encapsulation references with particular focus on single molecules, atomic chains, metal halides and polymers encapsulated inside CNTs. The encapsulation methods and the chemical and physical qualities of these novel materials are crucial for the future manufacturing of novel innovations in nanotechnology, and represent therefore the current stateof theart of encapsulation methods in advanced manufacturing.

Temporal Variation of the Pelagic Copepod Community in Acapulco Bay, México

Open Journal of Marine Science 2016年第1期6卷 40-48页

作者： Agustín A.

Between September 2009 and April 2010, superficial samples of plankton were collected in Acapulco Bay, using 150-μm mesh net, with the objective of studying the temporal variation in the abundance, species composition of the copepod community, and their relationship with some environmental parameters. Twenty-nine species of four orders were identified: 11 of Calanoida, 4 of Cyclopoida, 3 of Harpacticoida and 11 of Poecilostomatoida. A multivariate analysis (PCA) used to detect association between the abundance of copepod populations, and the environmental conditions through time, indicates a marked effect of the temperature and salinity parameters, on the abundance of the four copepod groups. The calanoids dominated numerically during most of the sampling months. The more important copepods genus were Corycaeus (7 species), andOithona (4 species). Nevertheless that the abundance of all copepod groups was affected temporarily by variations in the environmental conditions, the species composition inside the copepods community remained very stable.

Nanomaterials composed of metals and metal alloys are the most valuable components in emerging micro- and nano-electronic devices and innovations to date. The composition of these nanomaterials, their quantum chemical and physical properties, and their production methods are in critical need of summarization, so that a complete state of the art of the present and future of nanotechnologies can be presented. In this review, we report on the most recent activities and results in the fields of spintronics, nanophotonics, and nanomagnetics, with particular emphasis on metallic nanoparticles in alloys and pure metals, as well as in organic combinations and in relation to carbon-based nanostructures. This review shows that the combinatory synthesis of alloys with rare metals, such as scandium, yttrium, and rare earths imparts valuable qualities to high-magnetic-field compounds, and provides unique properties with emphasis on nanoelectronic and computational components. In this review, we also shed light on the methods of synthesis and the background of spintronic, nanomagnetic, and nanophotonic materials, with applications in optics, diagnostics, nanoelectronics, and computational nanotechnology. The review is important for the industrial development of novel materials, and for summarizing both fabrication and manufacturing methods, as well as principles and functions of metallic nanoparticles.

Superattracting cycles for some Newton type iterative methods

引用

Science China Mathematics 2011年第3期54卷 539-544页

作者： AMAT sergio BUSQUIER Sonia NAVARRO Emilie PLAZA sergio Departamento de Matemtica Aplicada y Estadistica Universidad Politécnica de Cartagena Ecole Généraliste d'Ingénieurs de Marseille (EGIM) Departamento de Matemticas Facultad de Ciencias Universidad de Santiago de Chile

The paper is devoted to the analysis of certain dynamical properties of a family of iterative Newton type methods used to find roots of non-linear equations. We present a procedure for constructing polynomials in such a way that superattracting cycles of any prescribed length occur when these iterative methods are applied. This paper completes the study begun in Amat, Bermúclez, Busquier, et al., (2009).
