Micro-patterning and actuation of phosphonium-based photo-responsive ionogels for micro-fluidic applications
The concept of âMicro-total-analysis-Systemsâ or âLab-on-chipâ has emerged over the past 20-years but, despite of the fact their incredible potential to revolutionise analytical science few outputs have reached the market so far[1]. Moreover, important issues like durability, disposability and cost of manufacture slow down the process of the integration of micro-fluidics into commercially relevant analytical products[2]. We believe that the next breakthroughs on micro-fluidic technology will come with the development of unconventional strategies in fundamental material science where âswitchableâ or âstimuli-responsiveâ materials, that can be remotely switched between forms with radically different properties, will substitute conventional fluid handling processes in analytical instrumentation[3].
We present the synthesis, surface patterning and characterisation of micro-valve structures and channel constrictors that underpin further movement towards the realization of next generation micro-fluidic components. The micro-structures are fabricated using novel materials (ionogels) based on phosphonium ionic liquids (ILs), and photo-responsive polymer gels with spiropyran moieties. Actuation can be achieved within seconds and easily controlled without the need for any physical contact between the stimulus source (light) and the resulting action, Figure-1. Furthermore, actuation time can be tuned by simply varying the IL-anion, for instance replacing [NTf2]- by [dca]- without changing the micro-fluidic device
Root Fernando-Kac subalgebras of finite type
Let be a finite-dimensional Lie algebra and be a
-module. The Fernando-Kac subalgebra of associated
to is the subset of all elements
which act locally finitely on . A subalgebra
for which there exists an irreducible module
with is called a Fernando-Kac subalgebra of

if in addition can be chosen to have finite Jordan-H\"older
-multiplicities. Under the assumption that is
simple, I. Penkov has conjectured an explicit combinatorial criterion
describing all Fernando-Kac subalgebras of finite type which contain a Cartan
subalgebra. In the present paper we prove this conjecture for
The great good place : coworking como espaço para aprender design uma framework exploratória
Abstract : In this paper we explore a conceptual framework based on
three lines of thinking/work from Patrick Cohendet
(Underground/Middleground/Upperground), Ray Oldenburg (The Great
Good Place), and Fred Garneti (Heutagogy or Self-determined Learning).
To demonstrate the relevance and feasibility of our proposed concept, we
review the key factors and definitions of these authors and their
work. Although not a theoretical framework, the present
paper aims to help us map a part of our research work within the context
of the Doctoral Programme in Design at IADE / Universidade Europeia,
which triangulates Coworking, Design Learning, and Heutagogy or selfdetermined
modes of learning. Ultimately, the aim is to generate
new evidence on how such a model of Coworking Design Learning can
benefit and betier suit contemporary Design learners.Neste artigo, exploramos uma estrutura conceptual baseada

Parameters of Malaysian identity in the novels of Lloyd Fernando and K S Maniam
This paper focuses on the works of two leading Malaysian novelists, Lloyd Fernando and K S Maniam, of Eurasian and Tamil descent respectively. Both of these men have published two novels to date, and both have developed themes pertinent to the identity of the land in which they live, and the peoples who live there, those whom the inimitable Dennis Bloodworth once termed the âmythical Malaysians.â The novels by Fernando and Maniam confirm that the parameters of Malaysian identity were, and remain, communally defined and exclusionist. In the contemporary world of nation-states, not all colonization is externally inspired
[Review of] Lloyd Fernando, ed., Malaysian Short Stories; K. S. Maniam, The Return; and Wong Meng Voon, Glimpses of the Past
These three books of fiction are set in the multilingual and multiracial context of Singapore and Malaysia, two Southeast Asian nations once part of the British Empire and now a region peopled by a volatile mix of indigenous Malays (roughly 45%) and immigrant Chinese (43%), Indians (10%), and Europeans (0.4%). Reflecting the diversity of this region, one book is a short story anthology by a Chinese (Wong), another a novel by an Indian (Maniam), and the third a collection of stories edited by an Eurasian ( Fernando). All three books have some astonishing strengths and some unfortunate lapses, with Maniam\u27s being the most sustained effort and Fernando\u27s the most generous sampling from these societies
The Mystery of the Black Convent. An Interesting Spanish Tale of the Eleventh Century.
In the year 1140, St. Alme entered the monastery of the Carthusians in the Spanish city of Castile, known St. Lawrence or the Black Convent. After three of outstanding example in virtue and holiness, Fr. Fernando, the abbot, noticed a significant change in the behavior of St. Alme. Since, he could not extract satisfactory explanation from St. Alme himself concerning his gloomy disposition, Fernando employed Fr. Martinez to look into the matter.
After a few days of intense spying, Fr. Martinez discovered that St. Alme was, actually, a woman disguised as a monk. The next night, Martinez saw Alme the sepulcher in the churchyard and go down. Martinez followed her, only to hear her shriek and faint on seeing a moving human form. Hurriedly, Martinez locked up the gate of the sepulcher, and gathered all the monks who quickly arrested the woman and the ghostly figure. He was none other than Anselm, an old friar.
The next day, Alme, revealed herself to Fr. Fernando, as Beatrice, the daughter of Anselm who was, actually, the noble man Raymond de Spalanza. Fernando forgave her when she explained how she was forced to enter the monastery in disguise in search of her ailing father who had joined the monastery for a quiet death. Meanwhile, Alphonso, the lover of Beatrice, also reached the monastery in search of her. It was explained that he could not marry Beatrice because he was incarcerated on a trumped up charge, by his own father. With Raymondâs assent, Fr. Fernando united the lovers in holy matrimony in the chapel of the Black Convent and lived happily ever after.https://epublications.marquette.edu/english_gothic/1018/thumbnail.jp
