Research in Architecture: Looking Backward and Forward: Forty-Year Experience in Architectural Research at the Faculty of Architecture STU

The introduction of my contribution contains a brief information on the Faculty of Architecture of the Slovak University of Technology in Bratislava (FA STU) and the architectural research performed at this institution. Schemes and priorities of our research in architecture have changed several times since the very beginning in early 50’s. The most significant change occurred after “the velvet revolution” in 1989. Since 1990 there have been several sources to support research at universities. The significant part of my contribution is rooted in my own research experience since the time I had joined FA STU in 1975 as a young architect and researcher. The period of the 80’s is characterized by the first unintentional attempts to do “research by design” and my “scientific” achievements as by-products of my design work. Some of them resulted in the following issues: conception of mezzo-space, theory of the complex perception of architectural space and definition of basic principles of ecologically conscious architecture. Nowadays I continue my research by design within the application of so called solar envelope in urban scale with my students.

Workplace Innovation and Technological Change. CEPS Special Report, September 2012

This paper explores the extent to which the illusive phenomenon of workplace innovation has pervaded workplaces in Europe and whether it could be one of the answers to Europe’s longterm social and economic challenges that stem from an ageing workforce and the need for more flexibility to stay competitive. Basic data drawn from European Working Conditions Survey conducted every five years by the Dublin-based European Foundation for the Improvement of Living and Working Conditions are supplemented by a series of case studies to look at the problems encountered in introducing workplace innovation and possible solutions. One set of case studies examines the following organisations: SGI/GI (Slovak Governance Institute (Slovakia), as representative of the world of small- and medium-sized enterprises; Oticon (Denmark) as representative of manufacturing companies; the Open University (UK), as representative of educational organizations; and FPS Social Security (Belgium) representing the public sector. Two final case studies focus on the country-level, one looking at of how a specific innovation can become fully mainstreamed (in the Netherlands and the ‘part-time economy’) and the other (Finland and TEKES) looking at how a government programme can help disseminate workplace innovation. These six case studies, together with the statistical analysis, constitute the main empirical value added of the report.

Women and writing c1340-c1650; the domestication of print culture

The transition from medieval manuscript to early printed book is currently a mmajor topic of academic interest, but has received little attention in relation to women's involvement. The essays in this volume both add female names to the list of those authors who created English Literature, and examine women's responses to older texts. Taking its cue from the advances made by recent work on manuscript culture and book history, this volume also includes studies of material evidence. These reveal women's participation in the making of books, and also the traces they left behind when handling individual volumes. Finally, studies of women's roles in relation to apparently ephemeral texts, such as letters, pamphlets and almanacs, challenge traditional divisions between public and private spheres and between manuscript and print.

Domesticating the calendar: the hours and the almanac in Tudor England

This article examines two genres of text which were extremely popular in the late-medieval and early modern periods, and it pays particular attention to women users. The printed almanacs of sixteenth-century England were enormously influential; yet their contents are so formulaic and repetitive as to appear almost empty of valuable information. Their most striking feature is their astrological guidance for the reader, and this has led to them being considered 'merely' the repository of popular superstition. Only in the last decade have themes of gender and medicine been given serious consideration in relation to almanacs; but this work has focused on the seventeenth century. This chapter centres on a detailed analysis of sixteenth-century English almanacs, and the various kinds of scientific and household guidance they offered to women readers. Both compilers and users needed to chart a safe course through the religious and scientific battles of the time; and the complexities involved are demonstrated by considering the almanacs in relation to competing sources of guidance. These latter are Books of Hours and 'scientific' works such as medical calendars compiled by Oxford scholars in the late middle ages. A key feature of this chapter is that it gives practical interpretations of this complex information, for the guidance of modern readers unfamiliar with astrology.

Non-hemagglutinating flaviviruses: molecular mechanisms for the emergence of new strains via adaptation to European ticks

Tick-borne encephalitis virus (TBEV) causes human epidemics across Eurasia. Clinical manifestations range from inapparent infections and fevers to fatal encephalitis but the factors that determine disease severity are currently undefined. TBEV is characteristically a hemagglutinating (HA) virus; the ability to agglutinate erythrocytes tentatively reflects virion receptor/fusion activity. However, for the past few years many atypical HA-deficient strains have been isolated from patients and also from the natural European host tick, Ixodes persulcatus. By analysing the sequences of HA-deficient strains we have identified 3 unique amino acid substitutions (D67G, E122G or D277A) in the envelope protein, each of which increases the net charge and hydrophobicity of the virion surface. Therefore, we genetically engineered virus mutants each containing one of these 3 substitutions; they all exhibited HA-deficiency. Unexpectedly, each genetically modified non-HA virus demonstrated increased TBEV reproduction in feeding Ixodes ricinus, not the recognised tick host for these strains. Moreover, virus transmission efficiency between infected and uninfected ticks co-feeding on mice was also intensified by each substitution. Retrospectively, the mutation D67G was identified in viruses isolated from patients with encephalitis. We propose that the emergence of atypical Siberian HA-deficient TBEV strains in Europe is linked to their molecular adaptation to local ticks. This process appears to be driven by the selection of single mutations that change the virion surface thus enhancing receptor/fusion function essential for TBEV entry into the unfamiliar tick species. As the consequence of this adaptive mutagenesis, some of these mutations also appear to enhance the ability of TBEV to cross the human blood-brain barrier, a likely explanation for fatal encephalitis. Future research will reveal if these emerging Siberian TBEV strains continue to disperse westwards across Europe by adaptation to the indigenous tick species and if they are associated with severe forms of TBE.

Drivers of change in mountain farming in Slovakia: from socialist collectivisation to the Common Agricultural Policy

The transformations in Slovak agriculture from the 1950s to the present day, considering both the generic (National and EU) and site-specific (local) drivers of landscape change, were analysed in five mountain study areas in the country. An interdisciplinary approach included analysis of population trends, evaluation of land use and landscape change combined with exploration of the perceptions of local stakeholders and results of previous biodiversity studies. The generic processes active from the 1950s to 1970s were critical for all study areas with impacts lasting right up until the present day. Agricultural collectivisation, agricultural intensification and land abandonment had negative effects in all study areas. However, the precise impacts on the landscape were different in the different study areas due to site-specific attributes (e.g. population trends, geographic localisation and local attitudes and opportunities), and these played a decisive role in determining the trajectory of change. Regional contrasts in rural development between these territories have increased in the last two decades, also due to the imperfect preconditions of governmental support. The recent Common Agricultural Policy developments are focused on maintenance of intensive large-scale farming rather than direct enhancement of agro-biodiversity and rural development at the local scale. In this context, local, site-specific attributes can and must form an essential part of rural development plans, to meet the demands for management of the diversity of agricultural mountain landscapes and facilitate the multifunctional role of agriculture.

On automorphisms of finite abelian p-groups

Let A be a finitely generated abelian group. We describe the automorphism group Aut(A) using the rank of A and its torsion part p-part A(p). For a finite abelian p-group A of type (k(1),..., k(n)), simple necessary and sufficient conditions for an n x n-matrix over integers to be associated with an automorphism of A are presented. Then, the automorphism group Aut(A) for a finite p-group A of type (k(1), k(2)) is analyzed. (C) 2008 Mathematical Institute Slovak Academy of Sciences.

Classification and characterization of places for mapping of environment using hierarchical neural network and omnivision

Mobile robots need autonomy to fulfill their tasks. Such autonomy is related whith their capacity to explorer and to recognize their navigation environments. In this context, the present work considers techniques for the classification and extraction of features from images, using artificial neural networks. This images are used in the mapping and localization system of LACE (Automation and Evolutive Computing Laboratory) mobile robot. In this direction, the robot uses a sensorial system composed by ultrasound sensors and a catadioptric vision system equipped with a camera and a conical mirror. The mapping system is composed of three modules; two of them will be presented in this paper: the classifier and the characterizer modules. Results of these modules simulations are presented in this paper.

Production and application of amylases of Rhizopus oryzae and Rhizopus microsporus var. oligosporus from industrial waste in acquisition of glucose

Amylases from Rhizopus oryzae and Rhizopus microsporus var. oligosporus were obtained using agro-industrial wastes as substrates in submerged batch cultures. The enzymatic complex was partially characterised for use in the production of glucose syrup. Type II wheat flour proved better than cassava bagasse as sole carbon source for amylase production. The optimum fermentation condition for both microorganisms was 96 hours at 30°C and the amylase thus produced was used for starch hydrolysis. The product of the enzymatic hydrolysis indicated that the enzyme obtained was glucoamylase, only glucose as final product was attained for both microorganisms. R. oligosporus was of greater interest than R. oryzae for amylase production, taking into account enzyme activity, cultivation time, thermal stability and pH range. Glucose syrup was produced using concentrated enzyme and 100 g L-1 starch in a 4 hours reaction at 50°C. The bioprocess studied can contribute to fungus glucoamylase production and application. © 2013 Institute of Chemistry, Slovak Academy of Sciences.

Microwave hydrothermal synthesis, characterisation, and catalytic performance of Zn1-xMnxO in cellulose conversion

Wurtzite-type Zn1-xMnxO (x = 0, 0.03, 0.05, 0.07) nanostructures were successfully synthesised using a simple microwave-assisted hydrothermal route and their catalytic properties were investigated in the cellulose conversion. The morphology of the nanocatalysts is dopant-dependent. Pure ZnO presented multi-plate morphology with a flower-like shape of nanometric sizes, while the Zn0.97Mn0.03O sample is formed by nanoplates with the presence of spherical nanoparticles; the Zn0.95Mn0.05O and Zn0.93Mn0.07O samples are mainly formed by nanorods with the presence of a small quantity of spherical nanoparticles. The catalyst without Mn did not show any catalytic activity in the cellulose conversion. The Mn doping promoted an increase in the density of weak acid sites which, according to the catalytic results, favoured promotion of the reaction. © 2013 Institute of Chemistry, Slovak Academy of Sciences.

O hibridismo textual em como agua para chocolate (1989), de Laura Esquivel: folhetim, almanaque, caderno de receitas e diário íntimo

Este artigo pretende discutir como se articulam, na estrutura híbrida do romance Como agua para chocolate, alguns gêneros textuais discursivos comumente dedicados à leitura de mulheres – folhetim, almanaque, caderno de receitas e diário íntimo –, cuja presença fica sugerida desde o subtítulo “novela de entregas mensuales, con recetas, amores y remedios caseros”. Esses gêneros se misturam na construção da narrativa, possibilitando, no âmbito da pós-modernidade, uma leitura crítica do papel da mulher na sociedade patriarcal da primeira metade do século XX.
