Asian cave-adapted diplurans, with the description of two new genera and four new species (Arthropoda, Hexapoda, Entognatha)

2021

Twenty-nine specimens of Diplura collected from eight caves in China and Myanmar contain two new genera, Hubeicampa Sendra & Lips gen. nov. and Mueggejapyx Sendra & Komerički gen. nov., as well as four new species, Anisuracampa ywangana Sendra & Komerički sp. nov., Hubeicampa melissa Sendra & Lips gen. et sp. nov., Pacificampa wudonghuii Sendra sp. nov. and Mueggejapyx brehieri Sendra & Komerički gen. et sp. nov. These cave-adapted taxa showcase an impressive diversity in morphological adaptation (troglomorphy) to cave ecosystems. Their sensorial equipment, setae and receptors in the cupuliform organ have unique forms (H. melissa gen. et sp. nov.), as well as the pretars…

¿Constructores de Mercado y de Estado? A propósito del Campomanes de V. Llombart

1994

This article seeks to discuss some of the conclusions V. Llombart’s study arrives at about the figure and the meaning of the count of Campomanes in the context of absolutism during the second half of the XVIIIth century. More specifically, it calls in question the idea of an action led by a reforming possibilism, half way between the non-enlightenment and the revolution, which would permit, besides, to establish a doubtful line of continuity among some of the reforms of the second half of the century and the plans of Cádiz. It proposes, on the contrary, to reintroduce an interpretative logic not so attached to the schemes of “market” and “state”.

Sequence and evolution of a hexamerin from the ant Camponotus festinatus.

2000

In the ant Camponotus festinatus, two different hexamerins accumulate stage-specifically during the late larval period and at various times in adults. These hexamerins serve as storage proteins and play important roles in brood nourishment and colony founding. We report an analysis of the cDNA sequence of C. festinatus hexamerin 2 (CfeHex2). The native protein contains 732 amino acids, which are moderately enriched in aromatic amino acids, aspartate and asparagine. Phylogenetic analyses show a close relationship of CfeHex2 to a putative toxin of the braconid wasp, Bracon hebetor. The divergence of Formicidae and Braconidae hexamerins was calculated to have begun 187 MYA, an estimate consist…

High-Frequency Polarization Variability from Active Galactic Nuclei

2021

The linear polarization of non-thermal emission encodes information about the structure of the magnetic fields, either from the region where the emission is produced (i.e., the intrinsic polarization angle) and/or from the screens of magnetized plasma that may be located on its way towards Earth (i.e., the effect of Faraday rotation). In addition, the variability timescale of the polarized emission, or its Faraday rotation, can be used to estimate the size of the region where the emission (or the Faraday rotation) originates. The observation of polarized emission from active galactic nuclei (AGN) and, in particular, its time evolution, also provides information about the critical role that …

Dipolar Rings of Microscopic Ellipsoids: Magnetic Manipulation and Cell Entrapment

2016

We study the formation and dynamics of dipolar rings composed by microscopic ferromagnetic ellipsoids, which self-assemble in water by switching the direction of the applied field. We show how to manipulate these fragile structures and control their shape via application of external static and oscillating magnetic fields. We introduce a theoretical framework which describes the ring deformation under an applied field, allowing to understand the underlying physical mechanism. Our microscopic rings are finally used to capture, entrap and later release a biological cell via magnetic command, i.e. performing a simple operation which can be implemented in other microfluidic devices which make us…

Magnetic functionalities in MOFs: from the framework to the pore

2017

In this review, we show the different approaches so far developed to prepare Metal-Organic Frameworks (MOFs) presenting electronic functionalities, with particular attention to magnetic properties. We will cover the chemical design of the framework necessary for the incorporation of different magnetic phenomena, as well as the encapsulation of functional species in the pores leading to hybrid multifunctional MOFs combining an extended lattice with a molecular lattice.

Fibre Bragg gratings tuned and chirped using magnetic fields

1997

The authors report on the use of magnetic fields in conjunction with magnetostrictive materials for tuning and chirping optical fibre Bragg gratings. The Bragg wavelength shifts as a consequence of the strain induced in the fibre by a magnetostrictive rod when a magnetic field is applied. A tuning range of 1.1 nm has been achieved by a magnetic field of 103 mT and the grating has been chirped by applying non-uniform magnetic fields.

A comparative study on campus sustainability in higher education sector in Hong Kong and Finland

2015

This thesis presents a comparative study examining the practices of campus sustainability in Higher Education Sectors between Hong Kong and Finland. Campus sustainability is a trend during the last decade as a result of numerous declarations and meetings for sustainable development in Higher education all over the world. In this thesis, the investigated areas are focused on environmental sustainability and Social sustainability. This study used the content analysis method to analyze public available documents from the selected fifteen Higher education institutions in Hong Kong and Finland. The first stage was a description of the current overall situations of campus sustainability in the tw…
