Cognitive deficits and memory impairments after COVID-19 (Covishield) vaccination
No full textVaccination is an essential public health strategy to control the 2019 Coronavirus (COVID-19) pandemic. While the benefits of the COVID-19 vaccines far outweigh the risks, side effects continue to be reported in the literature. We report a 65-year-old man who developed cognitive deficits and memory impairments following his first dose of Oxford AstraZeneca vaccine (Covishield). The onset of acute cognitive deficits and memory impairments could be another complication to COVID-19 vaccination that physicians and neurologists need to be warned to. Monitoring the safety of COVID-19 vaccines and describing side effects associated with them is essential to improve safety profiles and enhance public trust

Modelling Mechanically Ventilated Double Skin Facades with Integrated Shading Device
No full textDouble skin façades (DSF), are typically composed by two transparent envelope elements separated by a ventilated airspace. Such a technology can be applied both in new and existing buildings and may combine architectural value with energy efficiency. In the most common mechanically ventilated configurations the DSF air inlet came from the indoor environment and the outlet air returns to the HVAC system. Integrated shading devices are positioned between the skins. The assessment of the energy performance of buildings with DSFs requires proper dynamic simulation tools, based on models capable of predicting DSF heat transfer under variable boundary conditions, at the price of a reasonable computational effort. Many DSF simplified models have been developed and implemented in building simulation tools, but the validation of these tools is still an open issue, especially in presence of shading devices. The CFD modelling activity presented in this work aims at supporting the assessment of a DSF simplified model, specifically developed for the dynamic simulation of heat transfer in buildings. Such a model is based on an integral approach to the vertical channel, which is assumed to be separated into two channels when the shading device is used. Averaged surface heat transfer coefficients, depending on the geometry and flow regime, are adopted in order to represent convection inside the channels, according to the available correlations. The dataset of a measurement campaign, which was performed in a twin test facility on a mechanically ventilated DSF adopting both Venetian and roller blinds, was used to validate both the CFD model developed for this study, and the implementation of a former simplified model suitable for building simulation. The CFD approach allows for an assessment of the assumptions and hypotheses employed by the simplified model. Moreover, the CFD analyses provide a deeper insight on important aspects such as, the presence and impact of recirculation, the development of velocity and temperature profiles
Editorial: Social media neurosurgery and global neurosurgery
No full textIn today's digital world, social media has become a powerful tool in various fields, including neurosurgery. With widespread adoption, social media transforms neurosurgical education, professional development, and global collaboration. This editorial examines the expanding role of social media in neurosurgery, focusing on its impact on education, bridging global disparities, and the ethical challenges it presents
The Impact of Building Climatology on Architectural Design: A Simulation-Assisted Historical Case Study
No full textnone - see english versionThis study focuses on the design of a university building in Tel Aviv during the 1960's through a combination of building simulation and historical research. The combined methodology was used for tracing the way knowledge in building climatology was implemented iby the building's architects during its design, and for assessing of their proclaimed climatic intentions on the building's indoor conditions. The simulatiopn helped to affirm that the main climatic features of the original design - especially the clever massing of the building and the design of its sun protections - had a positive effect on the building's indoor climate
The Inter-individual Variance of the Defining Markers of Occupancy Patterns in Office Buildings: A Case Study
No full textnone - see english abstractRecently. increased efforts have been invested to enhance the sophistication of occupancy modelling approaches in building performance simulation. However, the effectiveness of such approaches depends on the robustness of the underlying empirical information. Thereby, an important question pertains to the existance and level of inter-individual differences in occupancy patterns. In the present contribution, we use a repository of monitored occupancy data in an office building to addess this problem empirically. While this repository does not include a large enough number of occupants to warrant a statistically significant treatment, it does allow for initiating a discussion of the diversity in observed occupancy profiles and the implications for relevant occupancy models in building performance simulation
Impact of Solar Irradiation Models on Simulated Hourly Energy Performance of Buildings
No full textnone - see english versionThis research work investigates the impact of the choice of solar irradiation models on the hourly energy needs, considering 72 simplified reference buildings in two European climates: Rome and Vienna. The full combination of 22 horizontal diffuse irradiance models and 12 irradiance models for tilted surfaces has been considered for the developement of hourly solar irradiation profiles, used as input in building energy simulation (i.e. TRNSYS). The results highlight that the variability of input solar irradiation leads to different levels of uncertainty in energy model predictions also depenting on the building characteristics
Supporting Visual Design for All: The Videa Approach
No full textnone - see english versionThis paper reports on a specific aspect of an ongoing research effort called the ViDeA project (Visual Design for All). Thereby, the capabilities of an existing visual simulation and analysis tool are being extended to specifically address the requirements of people with visual impairments. This research effort aims primarily at the development of effective means toward supporting the design and implementation of visually accessible solutions in the built environment. Thereby, a central objective is to enhance the mobility of people with sight restriction, and to support planers and architects to generate appropriate and efficient design solutions. The present contribution introduces the proposed tool. The outcome of the ViDeA project is expected to enhance the quality of visual performance guidelines and augment the capabilities of simulation-based design optimization tools

A Systematic Assessment of the Sensitivity of Building Performance Simulation Results with Regard to Occupancy-Related Input Assumptions
No full textnone - see english abstractThe considerable performance implications of occupants' presence and behaviour in buildings render the inclusion of corresponding models in building performance simulation applications both necessary and critical. In this context, an important question concerns the implications of selecting a specific occupany modelling approach for building performance simulation results. The present contribution adresses this issue by modelling an existing - continuously monitored - office building to obtain the annual and peak heating and cooling demands in a sequence of simulation runs. Thereby, different occupancy-related diversity profiles (standard-based, average and individual observation-based), randon realizations of these profiles (obtained from a stochastic occupancy model), and the original full-year observational data are deployed to represent occupancy in the simulation model. The simulation results suggest that the viability of simulation results is primarily dependent on the availability of reliable estimations of actual occupancy levels. In contrast, it is of little significaance wheter probabilistic or non-probabilistic representations of such estimations are deployed
