CULTURE OF THE SACRED SPACE
This book highlights the relationship between sacred architecture and tourism, specifically focusing on the role of interior design strategies. It explores how the interior design of sacred spaces can influence the tourist experience and shape their perception of these places. The book touches upon elements such as spatial organization, symbolism, material selection, lighting, and acoustics, all of which contribute to creating a meaningful and immersive environment for visitors.
It explores the architectural design, ideological motivations, and the historical context surrounding the palace's construction. The book also addresses the eventual abandonment of the project and its transformation of their uses, reflecting on the complexities of realizing utopian visions in architecture. It examines how the sanctuary's architectural design and spatial arrangement interact with the surrounding landscape, including elements such as topography, vegetation, and water features.
Moreover, it focuses on the interior design and explores the symbolism, spatial organization, artistic elements, and spiritual experiences associated with the dome interiors of these structures. The book showcases the historical context, cultural influences, and the evolution of design principles that shaped these remarkable spaces.
Also, this book investigates the transition of visionary architectural drawings from the realm of professional architects. Furthermore, it explores how architectural drawings serve as a medium for expressing imaginative and utopian ideas, and how this transition occurs in the context of architectural education
The Prevention of House Dust Mite Allergies in Pediatric Asthma
: This review provides a concise overview of preventive measures against dust mite allergies in pediatric populations, emphasizing the need for a comprehensive and evolving approach. Dust mites, ubiquitous microscopic arachnids, pose a significant threat to children's health, triggering allergies and asthma. Traditional preventive strategies such as regular cleaning, mattress covers, and humidity control are essential but warrant refinement. Empowering children through personalized hygiene education and exploring innovative bedding solutions showcase a forward-thinking paradigm. Collaboration with healthcare professionals and embracing technology-driven solutions ensures a holistic and adaptable approach to safeguarding pediatric health against dust mite-related ailments. This abstract underscores the importance of continually reassessing and innovating preventive measures to create resilient and health-conscious living environments for children
Luminosity determination using Z boson production at the CMS experiment
The measurement of Z boson production is presented as a method to determine the integrated luminosity of CMS data sets. The analysis uses proton-proton collision data, recorded by the CMS experiment at the CERN LHC in 2017 at a center-of-mass energy of 13 TeV. Events with Z bosons decaying into a pair ofmuons are selected. The total number of Z bosons produced in a fiducial volume is determined, together with the identification efficiencies and correlations from the same data set, in small intervals of 20 pb(-1) of integrated luminosity, thus facilitating the efficiency and rate measurement as a function of time and instantaneous luminosity. Using the ratio of the efficiency-corrected numbers of Z bosons, the precisely measured integrated luminosity of one data set is used to determine the luminosity of another. For the first time, a full quantitative uncertainty analysis of the use of Z bosons for the integrated luminosity measurement is performed. The uncertainty in the extrapolation between two data sets, recorded in 2017 at low and high instantaneous luminosity, is less than 0.5%. We show that the Z boson rate measurement constitutes a precise method, complementary to traditional methods, with the potential to improve the measurement of the integrated luminosity
Exploring the Reactivity of Melanins as Photocatalysts for Reductive Dehalogenations
Four melanin polymers prepared from different precursors (5,6-dihydroxyindole, 5,6-dihydroxyindole 2-carboxylic acid, 1,8-dihydroxynaphthalene and dopamine) have been adopted as photocatalysts in the reductive dehalogenation of a series of model α-halogen carbonyl derivatives. The best performing melanin was that obtained from 5,6-dihydroxyindole 2-carboxylic acid, which allowed to dehalogenate efficiently both bromomalonate esters and phenacyl bromide; on the other hand, chloromalonate esters were almost unreactive under the same reaction conditions. Electrochemical and control experiments enabled to elucidate the reaction mechanism, demonstrating the key role of electrons as charge carriers in the observed photocatalytic process
Thermodynamic models of the air spring on the high-speed pantograph
The modelling method of the air spring and its additional pneumatic system has been studied more frequently in recent years. As for the railway field, the study of the secondary suspension system of the bogie is the most popular, while little focus is on the air spring of the pantograph. In this paper, the modelling method of the air spring on the pantograph is investigated and developed. Four thermodynamic models are derived step by step, which can roughly be separated into two types. The first two models are established to express the relationship between the inner pressure and the vertical displacement of the air spring, and the effect of a regulator is illustrated and discussed. The latter two models that are developed from the first two models are set up to express the relationship between the vertical force and the vertical displacement of the air spring, where the effect of air spring material is illustrated and discussed. All four models are validated by comparing the simulation results with experimental results for frequency characteristics. Finally, the characteristics of the four proposed models are illustrated and discussed
Oscillator Design for D-Band Wireless Communication Applications
This manuscript presents a dual-core oscillator with third-harmonic extraction at 150GHz. The oscillator is built around a Colpitts topology, leveraging the harmonic-rich transistor drain current for its extraction. The addition of a transformer-based resonator boosts the loop gain, allowing for a reduction of the transistor size and parasitics while peaking the impedance at the third harmonic of the fundamental oscillation frequency. Small- and large-signal circuit analyses are presented in this paper to derive guidelines for design optimization. Two oscillator cores are also coupled for 3dB phase noise improvement. Magnetic coupling in the resonators is exploited for coupling, leading to a simple layout without extra parasitic elements and good robustness to mismatches. A test chip is designed and fabricated in Global Foundries 22nm CMOS FDSOI technology. The fundamental oscillation frequency is tunable from 47.5GHz to 51.5GHz, and the third harmonic is extracted from 142.5GHz to 154.5GHz. With 25.6mW from 0.8V voltage supply, the measured phase noise at 1MHz offset at 154.5 GHz is -87.4dBc/Hz, corresponding to -177.1dBc/Hz Figure-of-Merit (FoM). To the best of the authors' knowledge, this work demonstrates the lowest phase noise and the best FoM among reported CMOS oscillators delivering a signal in the same frequency range

Un dittico per la lingua della «Tregua»
Il saggio propone un affondo su due singoli fenomeni, che non solo hanno un’incidenza significativa nella lingua della Tregua, ma evidenziano la profonda solidarietà tra strutture grammaticali e sviluppo del pensiero di Levi. Il primo fenomeno è frequenza di una struttura sintattica a due livelli, che dapprima afferma, quindi motiva e documenta. Vera e propria ossatura concettuale sottesa all’intero edificio scrittorio di Levi, questa scelta va collegata allo statuto della lingua del testimone. Che acquista autorevolezza anche da una forma priva di vuoti o di contraddizioni. Il secondo fenomeno è quello dei cumuli aggettivali. L’indagine mostra come lo scrittore tenda a evitare gli schemi di tradizione retorica della sovrapposizione (serie sinonimiche) e dell’opposizione (ossimori), ma scelga piuttosto di aggregare aggettivi semanticamente divaricati, centrifughi, capaci – con la loro apertura a ventaglio – di catturare aspetti molteplici dell’oggetto qualificato
