No full textNo Europe without Brussels: The Berlaymont Building and the Development of the Léopold Area
No full textEurope and Brussels had a mutual dependency from the founding of the European Communities. This article explores the historic relation between local urban and the transnational development of post-war Europe. It ultimately raises the question to what extent there exists a dialogue between various actors involved to actively design and build the image of Europe in Brussels.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care.

Between La Tendenza and Neoliberty: Mauro Baracco Goes to Australia
No full textDiscussion of various relationships between Italian postmodern architecture (including works by Aldo Rossi, Gianni Braghieri and Gabetti&Isola), Australian postmodern architecture (including Edmond&Corrigan and Robin Boyd among others), and theoretical and design approach undertaken by the author (Mauro Baracco) as both a practitioner (director of Baracco+Wright Architects, Melbourne) and an academic (Associate Professor in Architecture and Urban Design, RMIT University, Melbourne)
A longitudinal study of neck and upper limb musculoskeletal disorders and alternative measures of vibration exposure
No full textObjective – To investigate the exposure-response relationships between alternative frequency weightings of hand-transmitted vibration (HTV) and neck and upper limb musculoskeletal disorders (MSDs) in a cohort of HTV workers.
Methods – In a 3-year longitudinal study, the occurrence of neck and upper limb MSDs were investigated in 249 HTV workers and 138 control men. In the HTV workers, MSDs were related to measures of daily vibration exposure expressed in terms of 8-hour energy-equivalent frequency-weighted acceleration magnitude [A(8)]. To calculate A(8), the acceleration magnitudes of vibration were weighted by means of four alternative frequency weightings of HTV. The associations between MSDs, individual characteristics, physical work load other than vibration and psychological strain were also investigated.
Results – The occurrence of upper limb MSDs was greater in the HTV workers than in the controls. After adjustment for potential confounders, the occurrence of elbow/forearm and wrist/hand MSDs increased with the increase of vibration exposure. A measure of model selection did not reveal any substantial difference in the performance of the alternative frequency weightings of HTV for the prediction of neck and upper limb MSDs. In the study population, age, hard physical work load and poor psychological well-being were associated with both neck and upper limb MSDs.
Conclusions – In this study there was evidence for significant exposure-response relationships between HTV exposure and MSDs in the distal sites of the upper limbs. There were no differences in the prediction of neck and upper limb MSDs between measures of daily vibration exposure calculated with alternative frequency weightings of acceleration magnitude
ORDER AND CHAOS. NORM AND FORM
No full textArchitecture is always the result of a generative process, carried out on different scale: those peculiar to the city (urban project) and those to the building; or even to the object, if we are in the field of industrial design.
“Shape generation” is based on issues of regularity and/or irregularities and it concerns the locking on and the enforcements of laws, principles, rules and exceptions. Architecture is not just a figurative art, and this is easier to understand if you look at the processes of generation of cities: even when it is seemingly spontaneous and unplanned, it highlights evolutionary "natural" processes due to the will and the case.
The paper analyzes the layout of different cities, the Pattern Language’s theory by Christopher Alexander - stating that it is beauty of shape and form which rules emerging life and remarking a set of problems and documented solutions for architects - and, as an evolution of those theories, our studies on Makoto Sei Watanabe’s Induction cities. This is a subject that a theoretical mathematician or a computer scientist might call “generative grammar”. So, what does it mean regularity or chaos in the developing of urban form
An overview of low back pain and occupational exposures to whole-body vibration and mechanical shocks
No full textThis paper offers an overview of the relation of low back pain (LBP) to occupational exposures to whole-body vibration (WBV) and mechanical shocks. LBP is a condition of multifactorial origin and is a very common health problem in the general population. Among occupational risk factors, epidemiological studies of driving occupations have provided evidence for strong associations between LBP and occupational exposures to WBV and mechanical shocks. Since it is hard to separate the contribution of WBV exposure to disorders in the lower back from that of other individual, ergonomic or psychosocial risk factors, a quantitative exposure-response relationship for WBV cannot be outlined precisely. Experimental research has provided biodynamic support to the findings of epidemiological studies, showing that in controlled laboratory conditions exposure to WBV can cause mechanical overload to the human spine. The EU Directive on mechanical vibration has established daily exposure action and limit values to protect the workers against the risk from WBV. There is some evidence that the EU exposure limit values are excessive, so much so that an elevated risk of LBP has been found for WBV exposures beneath the EU limit values. In the Italian arm of the EU VIBRISKS prospective cohort study of professional drivers, measures of internal lumbar load (compressive and shear peak forces), calculated by means of anatomy-based finite-element models, were found better predictors of the occurrence over time of low back disorders than the metrics of external exposure suggested by the EU Directive on mechanical vibration. Further biodynamic and epidemiological studies are needed to validate the findings of the VIBRISKS study
Transfer Hydrogenation Catalysis by a N-Heterocyclic Carbene (NHC) Iridium Complex on a Polyoxometalate Platform
No full textA divacant Keggin polyanion has been decorated with a N-heterocyclic carbene (NHC) iridium(I) organometallic complex to provide a molecular model of an Ir-based supported catalyst. The characterization of the hybrid compound has been performed by multinuclear NMR spectroscopy, infrared spectroscopy, cyclic voltammetry, and mass spectroscopy, and the results are in agreement with a bisfunctionalization of the polyoxometalate scaffold. The resulting supported homogeneous complex has been successfully used to catalyze the transfer hydrogenation from iPrOH to benzophenone [with a turnover number (TON) of 680 and a turnover frequency (TOF) of up to 540 h–1].European Research CouncilEuropean Science Foundatio
Occupational contact dermatitis in a gender perspective: North East Italian data 1996-2016
No full textBackground: Occupational contact dermatitis (OCD) ranks high among occupational diseases in Europe, but little is known as regards OCD and jobs in a gender perspective.
Objectives: To evaluate sex prevalence of OCD according to occupational sectors and agents involved. 27381 patients (1996–2016) with suspected irritant/allergic contact dermatitis (ICD-ACD) were evaluated in North-Eastern Italy. Each patient underwent: a standardized questionnaire, a dermatologist/occupational physician evaluation and a patch test.
Results: Females were younger at diagnosis (35.2 ± 11.6 years vs 37.7 ± 12.6 in males, p< 0.001) and had a lower ICD prevalence (OR 0.58, C.I. 95% 0.51 - 0.66, p < 0.001). Job categories most involved differed between sexes, with highest rank for healthcare professionals in females and machinery mechanics and filters for males. In females ACD percentage was higher in all job categories.
Conclusions: OCD characteristics differ between sexes, according to intrinsic and extrinsic factors. Use of personal care products, housekeeping products and outdoor work activities may account for different sensitization profiles
