Il Centro Progetti Tecno. Dal clima partecipativo degli anni sessanta al design globale del nuovo millennio
âLâeleganza discreta della tecnicaâ è lâespressione che Giampiero Bosoni (2011) dedica alla storica azienda Tecno fondata da Osvaldo e Fulgenzio Borsani nel 1953 a Varedo (MI). Lâinnesto della componente tecnologica nel processo di definizione estetica e tipologica dellâelemento dâarredo diventa il principio fondante dellâazienda, che vede la figura di Osvaldo Borsani come deus ex machina della visione progettuale. Se pur sin dalla fondazione furono intrapresi importanti tentativi dâincontro con contributi progettuali esterni, i Borsani interpretavano il rapporto con il progettista ancora come una figura interna alla âbottegaâ creativa ereditato dallâesperienza svolta con lâABV (Arredamenti Borsani Varedo.) Nella seconda metĂ degli anni sessanta gli architetti Valeria Borsani e Marco Fantoni propongono a Osvaldo Borsani di chiudere il ciclo delle firme personali nellâambito dei contributi interni allâazienda e di attivare quello che era giĂ , di fatto, un Centro Progetti Tecno (CPT), il quale viene âufficialmenteâ istituito a partire dal 1970.
Lâarticolo propone un approfondimento dedicato specificamente al CPT, lasciando la giĂ ben documentata storia della Tecno alla ricca letteratura a essa dedicata (Gramigna & Irace, 1992; Colonetti, 1996; Bosoni, 2011), nel tentativo di ricostruire una storia lunga trentâanni e descriverne il sistema dâinterrelazioni professionali attraverso documenti bibliografici, materiali dâarchivio e interviste.âThe discreet elegance of techniqueâ is the expression dedicated by Giampiero Bosoni (2011) to the historic Tecno Company, founded by Osvaldo and Fulgenzio Borsani in 1953 in Varedo (MI). The introduction of the technological factor into the aesthetic and typological development of furniture became the founding principle of the company, where the deus ex machina of the design vision was Osvaldo Borsani. Though since they first founded the company, the Borsani brothers made significant efforts to work with independent designers, they still viewed the designer as an in-house member of the creative âworkshopâ, a legacy of their experience with ABV (Arredamenti Borsani Varedo). In the late sixties, architects Valeria Borsani and Marco Fantoni suggested that Osvaldo Borsani end the cycle of designer names on pieces developed within the company and to formalize what was already de facto the Tecno Design Center (CTP), which was officially instituted in 1970.
This article presents a study devoted specifically to the CPT, leaving the well-documented history of Tecno to the wealth of dedicated literature (Gramigna & Irace, 1992; Colonetti, 1996; Bosoni, 2011), in an attempt to reconstruct its thirty-year history and to describe the system of professional interrelationships relying on bibliographical documents, materials from the archives and interviews
MADEC: Exploring new methodologies to transfer material knowledge into design disciplines
Due to the increased complexity of materials and production processes, the responsibility of
the development of a design is often left in the hands of technicians and production
personnel. This lack of knowledge about materials thus effectively creates a barrier between
the designer and the product. Bridging this gap represents a challenge to designers and
especially to the design schools. (Bak-Andersen 2013, p.69) Designers cannot know
everything but they can open their minds and develop a more conscious understanding of
this new field of design practice starting from a cultural point of view.
MADEC is a research group based in the Design Department of Politecnico di Milano in
2014 with the initial support provided by FARB founding (Fondi di Ateneo per la Riceca di
Base), which deals with the relation between design and materials in design history and
actuality. The center carries out researches on the âItalian Culture of Materials Designâ,
intended as the capacity of the Italian design to âinterpretâ materials and technologies to
generate products and environments innovation.
The main goal of MADEC is to develop vocational studentsâ and apprenticesâ design-related
competencies, integrating design into materialsâ research and development, to better
support commercial and societal applications benefiting from a cultural and multidisciplinary
knowledge.
This paper will report in particular two significant experiences carried on during the first year
of MADEC: the e-journal issue âItalian Material Design: learning from historyâ and the open
lectures cycle âThe Ideas and the Matterâ.
The general project has been basically divided in four main activities: creating a open source
on-line platform and a research and co-design network; enhancing academic papers and
publications both concerning design history studies and contemporary topics; organizing
transdisciplinary symposiums, workshops and seminars; participating to European projects
seeking for collaboration between researches, designers and material suppliers and
manufacturers.
To the conclusion the paper will try to figure out the points of force and weakness of the
research project and to trace future guidelines to improve its research and educational
methodology
Abet Laminati: il design delle superfici
Nel quadro di riferimento di questo numero, dedicato al rapporto tra la cultura dei materiali italiana e il mondo del design, una storia emblematica è quella della Abet Laminati. Una storia, soprattutto tra la fine degli anni settanta e gli anni ottanta, ampiamente descritta in relazione ai fenomeni del design italiano di quegli anni, su tutte quella del gruppo Memphis guidato da Ettore Sottsass. Quello che qui si vuole tracciare è un discorso piĂš approfondito e completo di come, quando e attraverso quali personaggi, unâindustria produttrice di materiali semilavorati come i laminati plastici, si sia evoluta fino a diventare un fenomeno cosĂŹ particolare e importante nella storia del design italiano. Analizzare come la modernitĂ intrinseca di questo materiale sintetico, per il quale proprio la scelta di dirigenti lungimiranti, di voler evidenziarne lâidentitĂ di prodotto artificiale, ha condotto lâazienda alla collaborazione con artisti, designers e architetti, noti e meno noti, provocando una delle piĂš vaste palestre di sperimentazione di design primario[1] degli ultimi sessantâanni. Questo è stato possibile attraverso il reperimento di materiali dâarchivio inediti, interviste, e un corposo numero di fonti bibliografiche messe a confronto
Detection of a novel bacterium of the genus Midichloria (family Midichloriaceae) in avian-borne Hyalomma marginatum ticks and their trans-Saharan migratory hosts
Introduction: Ticks are haematophagous ectoparasites of vertebrates habitually parasitizing avian species, which may contribute to tick dispersal across continents during migrations (Hasle 2013; Altizer et al., 2011). Midichloria bacteria can be transmitted to the vertebrate host during the tick bite (Bazzocchi et al., 2013; Serra et al., 2018). Although many avian species are common hosts of ticks harbouring Midichloria (e.g. Ixodes, Hyalomma), the circulation of this bacterium in birds has never been investigated. The aims of this study are: 1) evaluate the presence of Midichloria DNA in H. marginatum ticks and blood collected from trans-Saharan migratory birds; 2) quantify Midichloria bacteria in ticks through a novel quantitative PCR (qPCR).Material and methods: A total of 256 H. marginatum ticks and 97 blood samples were collected from three different migratory species (Phoenicurus phoenicurus, Saxicola rubetra and Sylvia communis) on Ventotene Island (Central Italy) and DNAs were extracted. A nested-PCR targeting the 16S rRNA gene of Midichloria was used to detect bacterial presence. Subsequently, primers targeting the gyrB gene of Midichloria and the cal gene of H. marginatum were designed and used in a qPCR for Midichloria quantification. Results were expressed as gyrB/cal copy numbers ratio.Results and discussion: 94% of Hyalomma ticks harbored DNA of Midichloria belonging to the monophylum associated with ticks, while the bacterial DNA was detected in 44.3% of blood samples. Furthermore, engorged ticks showed significantly higher bacteria load than unengorged ticks (Table 1; Wilcoxon sum-rank test: z=3.14; p=0.0017), similarly to what has been observed for M. mitochondrii in I. ricinus ticks.Conclusions: This work provides evidence for the presence of circulating Midichloria DNA in long-distance migratory birds, suggesting an enhanced worldwide spread of these bacteria across haematophagous ectoparasite populations. Future studies are necessary to increase the knowledge of Midichloria role in the biology of this tick species
The Design-driven Material Innovation Methodology
[EN] A new materials research scenario emerges from design field, where scientists, enterprises,
inventors, creative communities, and material industries are becoming deeply engaged in
the creative challenge to achieve material functionality and meanings ideas for disruptive
innovation. Considering and integrating design methods, technological approaches and
studies on innovation, the Material Design Culture Research Center (MADEC) of
Politecnico di Milano developed in the last years a specific methodology able to manage
the whole design process from tailor-made material to product systems, integrating
different actors of innovation, enhancing capabilities of open explorations, and reducing
the time-to-market for materials and products. This paper presents the DdMIM (Designdriven
Material Innovation Methodology) as a systematic approach and strategic tool for
research centers, design schools, practitioners and SMEs. A specific material could be a
starting point of the process, but not only. What the method really tries to do is to let
understand how to use technologies (and advanced materials) contextualizing them within
a wider socio-cultural and economic scenario. After a brief forward of the method
theoretical premises, this paper will analyzes the seven steps suggested by the
methodology: Data collection, Sensing, Sensemaking, Envisioning, Specifying, Setting up,
Placing. These phases are associated with a selection of case studies to help its
comprehension. Actually the DdMIM is part of the âDesign for Enterprisesâ the European
training program for SMEs, started this year and operating for the next two years in order
to help SMEs to enhance the capabilities for Design-Driven. In the âDesign for
Enterprisesâ training program the DdMIM is part of the module âDesign for Materialsâ,
and help enterprises to manage a design process for product and services innovation where
different actors like materials scientists, suppliers, creative communities and consumers are
getting engaged.Lecce, C.; Ferrara, M. (2016). The Design-driven Material Innovation Methodology. En Systems&design:beyond processes and thinking. Editorial Universitat Politècnica de València. 431-448. https://doi.org/10.4995/IFDP.2015.3243OCS43144
Effectiveness of the mechanical excitation applied to the olive paste: possible improving of the oil yield, in malaxation phase, by vibration systems
The mechanical vibrations characterized by a frequency lower than 200 Hz could promote the cells breakage and improve the oil extraction process by avoiding, at the same time, the negative effects on the commercial qualitative parameters due to the use of the heating during malaxation. Vibration tests were conducted by means of an electrodynamic shaker in order to find the optimal frequency levels of excitation, able to put in a resonant condition the olive paste. Sinusoidal accelerations at constant acceleration (120 m/s2), in a range between 5 and 200 Hz were explored. The 50 Hz and 80 Hz frequencies were able to put in resonant condition the olive paste. In the vibrated samples at 50 Hz (15 min of treatment), the maximum increment of the extraction efficiency (about 53% in comparison with the control), was observed. Further studies could be conducted in order to assess the synergic effect of the mechanical vibrations and the malaxation on the oil extraction efficiency, with the aim of reducing the time of the whole phase and avoiding changes in the oil quality traits
Scalable software framework for real-time data processing in the railway environment
Background: Ticks are obligate haematophagous ectoparasites of vertebrates and frequently parasitize avian species that can carry them across continents during their long-distance migrations. Ticks may have detrimental effects on the health state of their avian hosts, which can be either directly caused by blood-draining or mediated by microbial pathogens transmitted during the blood meal. Indeed, ticks host complex microbial communities, including bacterial pathogens and symbionts. Midichloria bacteria (Rickettsiales) are widespread tick endosymbionts that can be transmitted to vertebrate hosts during the tick bite, inducing an antibody response. Their actual role as infectious/pathogenic agents is, however, unclear. Methods: We screened for Midichloria DNA African ticks and blood samples collected from trans-Saharan migratory songbirds at their arrival in Europe during spring migration. Results: Tick infestation rate was 5.7%, with most ticks belonging to the Hyalomma marginatum species complex. Over 90% of Hyalomma ticks harboured DNA of Midichloria bacteria belonging to the monophylum associated with ticks. Midichloria DNA was detected in 43% of blood samples of avian hosts. Tick-infested adult birds were significantly more likely to test positive to the presence of Midichloria DNA than non-infested adults and second-year individuals, suggesting a long-term persistence of these bacteria within avian hosts. Tick parasitism was associated with a significantly delayed timing of spring migration of avian hosts but had no significant effects on body condition, whereas blood Midichloria DNA presence negatively affected fat deposits of tick-infested avian hosts. Conclusions: Our results show that ticks effectively transfer Midichloria bacteria to avian hosts, supporting the hypothesis that they are infectious to vertebrates. Bird infection likely enhances the horizontal spread of these bacteria across haematophagous ectoparasite populations. Moreover, we showed that Midichloria and tick parasitism have detrimental non-independent effects on avian host health during migration, highlighting the complexity of interactions involving ticks, their vertebrate hosts, and tick-borne bacteria
Prolonged higher dose methylprednisolone vs. conventional dexamethasone in COVID-19 pneumonia: a randomised controlled trial (MEDEAS)
Dysregulated systemic inflammation is the primary driver of mortality in severe COVID-19 pneumonia. Current guidelines favor a 7-10-day course of any glucocorticoid equivalent to dexamethasone 6â
mg¡day-1. A comparative RCT with a higher dose and a longer duration of intervention was lacking
Defining Kawasaki disease and pediatric inflammatory multisystem syndrome-temporally associated to SARS-CoV-2 infection during SARS-CoV-2 epidemic in Italy: results from a national, multicenter survey
Background: There is mounting evidence on the existence of a Pediatric Inflammatory Multisystem Syndrome-temporally associated to SARS-CoV-2 infection (PIMS-TS), sharing similarities with Kawasaki Disease (KD). The main outcome of the study were to better characterize the clinical features and the treatment response of PIMS-TS and to explore its relationship with KD determining whether KD and PIMS are two distinct entities.
Methods: The Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD (Kawasaki Disease Group - KDG) or KD-like (Kawacovid Group - KCG) disease between February 1st 2020, and May 31st 2020. Demographic, clinical, laboratory data, treatment information, and patients' outcome were collected in an online anonymized database (RedCAPÂŽ). Relationship between clinical presentation and SARS-CoV-2 infection was also taken into account. Moreover, clinical characteristics of KDG during SARS-CoV-2 epidemic (KDG-CoV2) were compared to Kawasaki Disease patients (KDG-Historical) seen in three different Italian tertiary pediatric hospitals (Institute for Maternal and Child Health, IRCCS "Burlo Garofolo", Trieste; AOU Meyer, Florence; IRCCS Istituto Giannina Gaslini, Genoa) from January 1st 2000 to December 31st 2019. Chi square test or exact Fisher test and non-parametric Wilcoxon Mann-Whitney test were used to study differences between two groups.
Results: One-hundred-forty-nine cases were enrolled, (96 KDG and 53 KCG). KCG children were significantly older and presented more frequently from gastrointestinal and respiratory involvement. Cardiac involvement was more common in KCG, with 60,4% of patients with myocarditis. 37,8% of patients among KCG presented hypotension/non-cardiogenic shock. Coronary artery abnormalities (CAA) were more common in the KDG. The risk of ICU admission were higher in KCG. Lymphopenia, higher CRP levels, elevated ferritin and troponin-T characterized KCG. KDG received more frequently immunoglobulins (IVIG) and acetylsalicylic acid (ASA) (81,3% vs 66%; p = 0.04 and 71,9% vs 43,4%; p = 0.001 respectively) as KCG more often received glucocorticoids (56,6% vs 14,6%; p < 0.0001). SARS-CoV-2 assay more often resulted positive in KCG than in KDG (75,5% vs 20%; p < 0.0001). Short-term follow data showed minor complications. Comparing KDG with a KD-Historical Italian cohort (598 patients), no statistical difference was found in terms of clinical manifestations and laboratory data.
Conclusion: Our study suggests that SARS-CoV-2 infection might determine two distinct inflammatory diseases in children: KD and PIMS-TS. Older age at onset and clinical peculiarities like the occurrence of myocarditis characterize this multi-inflammatory syndrome. Our patients had an optimal response to treatments and a good outcome, with few complications and no deaths
