Re-tracing the Senne: Making the invisible river in Brussels visible
No full textResearch about the covered river Senne in Brussels. This former river seems to be invisible, but this research shows that this former industrial river still lives in the city (within the architecture and the urban structure). What can a revitalization of this covered river mean? And how does architecture relate to this revitalized space?The Senne OasisArchitecture, Urbanism and Building Sciences | Urbanis
Aksjologia Rene Le Senne\u27a a aksjologia Józefa Tischnera.
No full textThe article deals with the philosophy of Le Senne in which man is determined by character and by values. The self results from relation to values. Cognition of God does not create conceptual metaphysics, but it is human act directed to the value. The author claims that Le Senne’s metaphysic is the axiology but without the hierarchy of values and criteria. The source of value is God who is not summum esse but Value. For Le Senne value and not being is a priority. That is the one of many similarities to Tischner’s philosophy.The article deals with the philosophy of Le Senne in which man is determined by character and by values.

Walls that teach: the youth center in Anderlecht
No full textThe story started from the invisible river Senne on the urban scale of Brussels, concentrating on the wall which is both spolia on site and the identity of my youth center. The archaeological idea of Spolia keeps me discovering the existing value, then constantly thinking of collecting, composing and re-using. Once existing fragments collide with new ones, the process of bricolage comes up. The wall on site is the ghost of Senne that could be seen as spolia on immaterial, but now it became the backdrop of people’s lives in the neighborhood, where the youths there are facing issues such as stigmatization. The strategy of the urban proposal and architectural part is to use the wall as a frame to turn the situation from segregation and at the meanwhile to break youths’ mental wall. The old wall owns the collective memory, speaks for space. That’s why the walls teach
Nanocapsules with stimuli-responsive moieties for controlled release employing light and enzymatic triggers
No full textThe development of stimuli-responsive nanomaterials, that possess tailored functional properties for the release of specific compounds, is of particular interest. To this extent, controlling the release of molecules at the desired target is an important parameter to regulate chemical and/or biological reactions at a more profound level in a wide variety of applications. In the present work, we report on the development of dual-responsive thiourethane-urethane nanocapsules synthesizedviaan interfacial polymerization reaction executed at the droplet interface using the inverse miniemulsion technique. Evidenceviamorphological and controlled release investigations indicate that our nanocapsules are able to encapsulate hydrophilic compounds with high efficiency in their aqueous core and allow for its selective release upon exposure to UV light and the enzyme esterase. Moreover, we demonstrate the efficient encapsulation of the fragrance molecule geranyl acetate and the anticancer drug doxorubicin. For the latter, we demonstrate its apoptotic effect after being released in MCF 7 breast cancer cells. Overall, these nanocapsules can be used for a wide variety of applications where a selective release of the payload is desired.S. S. is an SB PhD Fellow at the FWO (Research Foundation Flanders). S.

Educational Institution For Textiles and Ceramics In Cureghem: In Search For The Border, The Interzone And The City
No full textThe project is set in a fragmented neighbourhood called Cureghem in the south-west of Brussels. The newspapers often portray the neighbourhood as poorly developed with low living standards. The project considers that spatial transformation is only acceptable if it responds to current-day social and spatial issues. In the urban design of the project in Cureghem, the Senne is used to shape the park in the urban plan, not because the Senne is spolia, but because of the need for readable and climate-responsive exterior spaces. The smaller scale of the architecture aims to stimulate peoples feeling of belonging and ability to develop their crafts. In the design, the spolia of local craft and economic activity of textiles, ceramics and building materials is used as an inspiration for the program. Both in the urban plan and architecture, the spatial fragmentation is explained by zooming into the border conditions of the fragmented urban block. These conditions explain the current problems that are present. One of the theoretical explorations was to answer the question: What can be defined as a border or edge, what do they consist of, and are they culturally defined? To answer this question a lot of disciplines had to be addressed, from geology and archaeology to anthropology and the body. The research on this started with a very abstract approach to understanding borders, by zooming in on existing theories on borders in fields ranging from archaeology to performance art.SpoliaArchitecture, Urbanism and Building Sciences | Urbanis
Investigating Episode Prioritisation in Alert-Driven Attack Graphs: Analysing PICA: A Novel Approach to Episode Prioritisation
No full textIntrusion Detection Systems (IDSes) detect malicious traffic in computer networks and generate a large volume of alerts, which cannot be processed manually. SAGE is a deterministic algorithm that works without a priori network/expert knowledge and can compress these alerts into attack graphs (AGs), modelling intruders’ paths in the network. These AGs are too high in quantity/complexity for manual analysis, creating the necessity for prioritising individual attack stages (ASes). The existing prioritisation metric does not take into account graph properties and is not granular enough to function on a node level. We propose PICA, an urgency metric inspired by the CIA triad (Confidentiality, Integrity and Availability) and the graph properties. It works on a node level and an attack-stage level. PICA is evaluated by comparison with the current implementation, based on AGs generated by SAGE using open-source intrusion alert datasets. The evaluation is based on the number and the type of the discovered attack stages. Results show that PICA manages to discover ASes that contain nodes with a highin-degree but fails at discovering urgent ASes that contain many nodes with low in-degrees. Compared to the baseline, the ASes are distributed more evenly over the different urgency levels. Analysis of urgent node positioning revealed that sub-AGs lose information when objectives (final goal in a path) are also starting nodes. Changing the weights of the CIA triad showed a clear bias in results towards the larger weights, as was intended. Finally, further work is proposed for PICA and in the generation process of SAGE’s AGs.CSE3000 Research ProjectComputer Science and Engineerin
Against the wall: Elderly residential care and child daycare centre
No full textThe theme of the studio, spolia, is a term from archaeology, which is to place remnants in a new environment. The project started research of a historical river in the city—the Senne in Brussels. The river influenced the urban development of the whole city morphologically and typologically. Interventions regarding the river show how local people treat spolia. The site is also located along the trace of Senne. A typical wall was formed because of the covering the Senne. It indicates the history but also segregates and influences current situations. It serves as such an important role that it should not be easily discarded. It is the spolia for this site. There is a big difference between the two sides of the wall--living and working, nature and the built environment, leisure and production. The urban concept is to reuse the wall to activate the neighbourhood, increase housing and public facilities and remove the productive constructions to the suburban area. The urban regards the wall as the main spolia and returns the centre of the block to the public. The wall frames the public facilities and parks of the community garden. The architectural proposal continues the focus on the wall as the spolia and explores how to treat it on the architectural scale. The project deals with three issues: the urban gestures facing different sides, the combination of the elderly and the children and the reuse of the existing wall. Among these, to reuse and reconfigure the wall intertwine the other two and becomes the main spine of my project. In the architectural scale, the content of spolia can be enriched. The wall is not only a line. It has the thickness; it has structure; it has a function. The wall acts as the perimeter of the project and organizes programs. The two user groups share an event hall and the kitchen. They have visual connections but also have their privacy. The façade intends to remain the solidness of the wall and make the new open and light while ties in with the old. So for the new façade, the frame can open up the courtyard by reducing the mass of the wall. The original texture of the old is remained to highlight the old wall. The façade also uses similar bricks of the old wall but uses different bonding to create a subtle difference between new and old. Especially for the entrance, light and translucent material is applied to the cladding to express an opening of the old. The interior use wood floor and plaster wall to release the heaviness of the texture of the bricks. In conclusion, my project lies partly in the urban solution. It articulates and celebrates an existing wall from urban scale down to materialization. In different stages, the content of the wall is enriched and enhanced.<br/
The municipal police : their place in American society
No full textThis paper is a study of the place of the municipal police in American society. The specific question to which it is addressed is, to what extent and in what ways are the police integrated into the larger society? This question is pursued in the context of five criteria developed from the general theory of Talcott Parsons. The criteria are as follows: (l) that the values which are institutionalized in the police reflect the major value orientation of the society as a whole, namely, universalism and achievement; (2) that the reward system of the society be integrated with the occupational roles of the police; (3) that the occupational structure of police work be open; (4) that the police function as a subordinate part of a larger system; and (5) that there is an indication of mutual identification between the police and the larger society resulting in loyalty between the two. The sources used for the study are published and unpublished literature and the author\u27s own research which she conducted with three Illinois police departments. The focus of these sources is primarily upon the way the municipal police are organized, their procedures of work, the milieu within which they function, the kinds of communication between them and their various publics such as citizens, legislatures, and the media, and the opinions which they express about their work and their publics. The author\u27s research includes two phases: (l) participant-observation of police officers on their work assignments and in police stations, and (2) the administration of an interview schedule to officers on an individual basis. The conclusion of the study is that the police are poorly integrated with the remainder of the society. Several recommendations are offered in the last chapter which the author believes would promote a more integrated social system
PEGylating poly(p-phenylene vinylene)-based bioimaging nanoprobes
No full textHypothesis: Conjugated polymer nanoparticles (CNPs) have attracted considerable attention within bioimaging due to their excellent optical properties and biocompatibility. However, unspecific adsorption of proteins hampers their effective use as advanced bioimaging probes. Controlled methodologies made possible tailor-made functional poly(p-phenylene vinylene), enabling one-pot synthesis of CNPs containing functional surface groups. Hence, it should be feasible to PEGylate these CNPs to tune the uptake by cell lines representative for the brain without imparting their optical properties. Experiments: CNPs consisting of the statistical copolymer 2-(50-methoxycarbonylpentyloxy)-5-methoxy-1,4-phenylenevinylene and poly(2-methoxy-5-(30,70-dimethoxyoctyloxy)-1,4-phenylenevinylene) were fabricated by miniemulsion solvent evaporation technique. Surface carboxylic acid groups were used to covalently attach amine-terminated polyethylene glycol (PEG) of different molecular weights. We investigated the effect of grafting CNPs with PEG chains on their intrinsic optical properties, protein adsorption behavior and uptake by representative brain cell lines. Findings: PEGylation did not affect the optical properties and biocompatibility of our CNPs. Moreover, a significant decrease in protein corona formation and unspecific uptake in central nervous system cell lines, depending on PEG chain length, was observed. This is the first report indicating that PEGylation does not affect the CNPs role as excellent bioimaging tools and can be adapted to tune biological interactions with brain cells.

From primal repression to perceptual signs: Silvia Bleichmars contributions to psychoanalysis
No full textNesta dissertação são apresentadas duas contribuições originais de Silvia Bleichmar em relação a Laplanche: recalque originário e signos de percepção. Partindo das observações de Laplanche sobre a ideia freudiana que considera o inconsciente fundado pelo recalque originário, Silvia Bleichmar ampliou o conceito, produzindo importantes contribuições em comparação ao pensamento freudiano e laplancheano. A autora articulou o recalque originário com os destinos pulsionais anteriores ao recalque, tornando-o um conceito metapsicológico passível de ser observado clinicamente, sobretudo na clínica de crianças. O recalque originário, em Silvia Bleichmar, longe de ser um processo mítico em algum momento, aproxima-se da ideia freudiana de recalque propriamente dito. Para Bleichmar, tal como em Freud, o recalque originário extrai sua força inicial de contrainvestimentos. No entanto, a autora entende que estes contrainvestimentos seriam originados no outro, pela interdição ao autoerotismo infantil. Outra importante contribuição da autora para a psicanálise foi sua conceituação sobre signos de percepção, tradução para a expressão alemã Wahrnehmungszeichen (Wz), usada por Freud em seu modelo de aparelho psíquico apresentado na Carta 52 a Fliess. Laplanche questiona se o termo Zeichen deveria ser entendido como signos ou indícios, fazendo sua escolha pela palavra signos. Para este autor, os signos de percepção se equivalem às mensagens enigmáticas, portanto, seriam portadores de mensagens. Silvia Bleichmar entende que Zeichen seriam indícios, pegadas, marcas, vestígios, huellas (em espanhol), dando ênfase ao caráter indiciário dos signos de percepção. A autora partiu da concepção de Charles S. Peirce sobre signos indiciários para articular sua própria concepção de signos de percepção. Para a autora, estes seriam as primeiras inscrições pulsionais que podem permanecer no psiquismo como arcaico se não transcritas ou as inscrições advindas de traumatismos severos, a qualquer momento, que ficam igualmente sem possibilidade de transcrição no psiquismo. Assim, o arcaico seria formado pelos signos de percepção que permanecem sem transcrições enquanto o originário seria o conteúdo do inconsciente originariamente recalcadoTwo original Silvia Bleichmars contributions to Laplanche are presented in this essay: the primal repression and the perceptual signs. Stemming from Laplanches observations on the Freudian conception that considers the unconscious founded by the primal repression, Silvia Bleichmar expanded the concept, producing important contributions in comparison to the Freudian and the Laplanchean lines of thought. The author connected the primal repression to the Freudian destinies of the drive (instinct) existing prior to repression, which made it a metapsychological concept subject to clinical observation, most of all in the work with children. In Silvia Bleichmars thinking, far from being a mythical process at some point, the primal repression is close to the Freudian idea of repression itself. To Bleichmar, as well as to Freud, the primal repression extracts its initial strength from anticathexes. Nevertheless, the author believes that these anticathexes stem from the other through the interdiction of child auto-erotism. Another important contribution of the author to psychoanalysis was her conceptualization of perceptual signs, which is a translation of the German expression Wahrnehmungszeichen (Wz), used by Freud in his model of psychic apparatus presented in the Letter 52 to Fliess. Laplanche questions if the term Zeichen should be understood as signs or indexes, preferring the word signs. For him, the perceptual signs are equivalent to the enigmatic messages, therefore they would be message carriers. Silvia Bleichmar believes that Zeichen are indexes, footprints, marks, vestiges, huellas (in Spanish), emphasizing the indexing character of the perceptual signs. Therefore, deriving from Charles S. Peirces conception of indexing signs, the author built her own conception of perceptual signs. For her, these would be the first drive inscriptions that may remain in the psyche as archaic if not transcript, as well as the inscriptions stemming from severe trauma, at any point, which equally remain without transcription in the psyche. Hence, the archaic would be composed by the perceptual signs that remain without transcriptions whereas the primal would be the content of the primally repressed unconsciou
