A comparative study on the quality of air in offices and homes.
2013
The main purpose of this study was to collect data on some of the factors that contribute to indoor air quality and to discomfort, in order to take the proper actions that can reduce the level of air pollution within houses and offices. To ascertain the contamination degree total bacterial counts, total fungal counts, suspended particulate matter, air temperature, and relative humidity have been determined. Additionally, mathematical statistical models have been elaborated for the total bacterial count, respirable particulate matter and humidity. A total number of 40 indoor air samples were collected from office and houses. The results shows that approximately 45% of the air samples from ho…
Effect of Integrating Photovoltaic Systems on Electrical Network Losses Considering Load Variation
2018
Planning of Distributed Generation (DG) units in the power distribution networks is an important issue, one of the most important considerations that is directly affected by installing DG units is the power losses. Improper allocation of DG units to the grid can lead to a noticeable increase in the power losses. Moreover, the load variation is considered as critical matter when studying the optimal scenario that minimizes the power losses in the network. The aim of this paper is to investigate the effect of integrating photovoltaic (PV) units on the distribution network losses considering load variation. The optimal parameters of the DG units were calculated for the various load demands in …
A Renewable Energy mix to Supply the Balearic Islands: Sea Wave, Wind and Solar
2018
The paper investigates the status of the electrical energy sector in the Balearic Islands (Spain). In order to improve the energetic sustainability, this work analysis the availability of renewable energy sources, focusing the attention on sea wave, wind and solar. For the utilization of sea wave source, an innovative device is proposed.
A Prototype of Wireless Sensor for Data Acquisition in Energy Management Systems
2018
A prototype of a wireless sensor for monitoring electrical loads in a smart building is designed and implemented. The sensor can acquire the main electrical parameters of the connected load and, optionally, other physical quantities (e.g., room temperature). Unlike other wireless sensors in literature, the proposed sensor is cheap and small, exploits the Wi-Fi network that is commonly available inside buildings, and uses a lightweight message-based communication paradigm. Besides the sensor node, two management nodes are also implemented to manage sensor reconfiguration and the persistence of data. The measured data are stored in an SQLite database and can be used for various purposes, e.g.…
THE “ZISA” IN PALERMO: BIOCLIMATIC ASPECTS OF ITS ARCHITECTURE
2010
In the present work is examined, as an ante-litteram example of summer residence and bioclimatic archi-tecture, the ancient castle of the Zisa (from the Arabic 'al-aziz = noble, shining, glorious), meaningful work of Arab-Islamic character built up at the beginnings of the XII century (fig. 1). The building holds a notable importance as it is one of the few examples of Norman civil architecture with elements of Arab-Islamic character and Byzantian culture, but also because it had been conceived according to the most re-fined Islamic techniques of free cooling. The building (fig. 1) presents itself like a massive rectangular construction developed on three levels. On the architectural plan t…
ID4 Is Required for Normal Ependymal Cell Development
2021
Ependymal cells are radial glia-derived multiciliated cells lining the lateral ventricles of the brain and spinal cord. Correct development and coordinated cilia beating is essential for proper cerebrospinal fluid (CSF) flow and neurogenesis modulation. Dysfunctions of ependymal cells were associated with transcription factor deregulation. Here we provide evidence that the transcriptional regulator ID4 is involved in ependymal cell development and maturation. We observed that Id4-deficient mice display altered ventricular cell cytoarchitecture, decreased ependymal cell number and enlarged ventricles. In addition, absence of ID4 during embryonic development resulted in decreased ependymal ce…

Ten essential features of European dual career development environments: A multiple case study
2021
Aim: Dual career development environments (DCDEs) support athletes’ effort in combining their competitive sporting careers with education or work. The characteristics of the environments may differ across cultures. The aim was to identify essential features of DCDEs based on a cross-case analysis of seven European DCDEs in Belgium, Denmark, Finland, Slovenia, Spain, Sweden, and the United Kingdom within the Erasmus+ Sport project “Ecology of Dual Career”. Design: The study was designed as a multiple case study and based on two holistic ecological working models (Henriksen et al., 2020). The cross-case analysis included series of focus group discussions, in which two-three researchers from e…
Dalibor Vesely e la complessità culturale del progetto
2016
Dalibor Vesely ebbe una enorme influenza sulla cultura archiettonica inglese fino alla sua recente scomparsa, specialmente per la sua figura di docente. Con Rykwert insegnò in un famoso corso postlaurea all'Essex e successivamente a Cambridge. La sua concezione del progetto architettonico era fortemente influenzata dalla fenomenologia e dall'ermeneutica. The article outlines the outstanding relevance of Dalibor Vesely an architect and teacher who has recently disappeared. He was born and brought up in Czechoslovakia but, since the early Sixties, he has lived in London where he was considered an authority for his insightful approach to architecture. The article is focused on his conception o…
Spazio, Rappresentazione, Architettura

El problema de la representación del espacio construido (la arquitectura) no puede prescindir de la concepción de espacio físico que durante siglos el hombre ha formulado.
