Billboards. Two projects by Maurizio Montagna
Architecture, city, device, time: all of these issues are taken into account by the Milanese photographer Maurizio Montagna. A keen interpretation of places in their anthropic and cultural transformation emerges from all his works. This article aims to focus on two different projects, Billboards 2008 and Billboards site-specific Latronico 2018, in which the author reflects on the relationship among the object, the subject and the context/landscape where they belong
Pharmaceuticals in the Built and Natural Water Environment of the United States
abstract: The known occurrence of pharmaceuticals in the built and natural water environment, including in drinking water supplies, continues to raise concerns over inadvertent exposures and associated potential health risks in humans and aquatic organisms. At the same time, the number and concentrations of new and existing pharmaceuticals in the water environment are destined to increase further in the future as a result of increased consumption of pharmaceuticals by a growing and aging population and ongoing measures to decrease per-capita water consumption. This review examines the occurrence and movement of pharmaceuticals in the built and natural water environment, with special emphasis on contamination of the drinking water supply, and opportunities for sustainable pollution control. We surveyed peer-reviewed publications dealing with quantitative measurements of pharmaceuticals in U.S. drinking water, surface water, groundwater, raw and treated wastewater as well as municipal biosolids. Pharmaceuticals have been observed to reenter the built water environment contained in raw drinking water, and they remain detectable in finished drinking water at concentrations in the ng/L to μg/L range. The greatest promises for minimizing pharmaceutical contamination include source control (for example, inputs from intentional flushing of medications for safe disposal, and sewer overflows), and improving efficiency of treatment facilities
Una nuova proposta per un antichissimo problema. Deo/dea in Verg. Aen. II 632
L'articolo riesamina la vexata quaestio relativa alla variante deo/dea contenuta in Verg. Aen. II 632, con nuove considerazioni per la risoluzione del problema.About Verg. Aen. II 632 deo / dea the communis opinio, though persuaded that in any case the reference is to Venus, however prefers deo as lectio difficilior. Also the author of this article believes that deo is the right reading, but she is of the opinion that this word in the context denotes all deities in general, and in the Aeneas’ expression ducente deo she recognizes the pietas erga deos that Aeneas had preserved intact even amid the Troy’s ruin

Zur Entstehungszeit und zum Text von Ps.-Victorinus, De Iesu Christo Deo et Homine
The author of the small poem De Iesu Christo Deo et Homineis influenced by Iuvencus and Prudentius, but his model, as argued, is Sedulius, who offers the terminus post quem. Textual notes, critical and interpretative, conclude the paper
A Comparative Study between Conventional Diaphragmatic Breathing Exercise and Virtual Reality-based Diaphragmatic Breathing Exercise on Quality of Life in Chronic Obstructive Pulmonary Disease Patients: A Randomized Control Trial
Background and Aim:
Breathing exercise is an exercise intended to promote effective and healthy breathing and breathing control. Virtual reality (VR) is defined as a computer-generated simulation, such as a set of images and sounds that represent a real place or situation that can be interacted within a seemingly real or physical way by a person using special electronic equipment. Breathing exercises with VR have shown benefits over conventional diaphragmatic breathing exercises in normal individuals in many new studies. We propose the use of a novel VR-based approach as a respiratory biofeedback to improve breathing patterns in chronic obstructive pulmonary disease (COPD) patients, decrease their work of breathing, and improve breathing control.
Materials and Methods:
In a randomized controlled study involving 72 COPD patients divided into two groups of 36 in each, the control and experimental groups performed a short 5 min breathing exercise for 6 consecutive days. In experimental group patients performed breathing exercise with VR goggles while in controls they performed without VR goggles.
Results:
Both the control and experimental groups showed improved changes in vitals and better quality of life, but not statistically as significant when compared to each other.
Conclusion:
Future studies need to address the long-term effects and stability of the results with a larger sample size, compare the approach with the existing treatments, and make the required smaller changes to the program for better outcomes

Similarity analysis of the momentum field of a subsonic, plane air jet with varying jet-exit and local Reynolds numbers
A similarity analysis is presented of the momentum field of a subsonic, plane air jet over the range of the jet-exit Reynolds number Reh (≡ Ubh/υ where Ub is the area-averaged exit velocity, h the slot height, and υ the kinematic viscosity) = 1500 − 16 500. In accordance with similarity principles, the mass flow rates, shear-layer momentum thicknesses, and integral length scales corresponding to the size of large-scale coherent eddy structures are found to increase linearly with the downstream distance from the nozzle exit (x) for all Reh. The autocorrelation measurements performed in the near jet confirmed reduced scale of the larger coherent eddies for increased Reh. The mean local Reynolds number, measured on the centerline and turbulent local Reynolds number measured in the shear-layer increases non-linearly following x1/2, and so does the Taylor microscale local Reynolds number that scales as x1/4. Consequently, the comparatively larger local Reynolds number for jets produced at higher Reh causes self-preservation of the fluctuating velocity closer to the nozzle exit plane. The near-field region characterized by over-shoots in turbulent kinetic energy spectra confirms the presence of large-scale eddy structures in the energy production zone. However, the faster rate of increase of the local Reynolds number with increasing x for jets measured at larger Reh is found to be associated with a wider inertial sub-range of the compensated energy spectra, where the −5/3 power law is noted. The downstream region corresponding to the production zone persists for longer x/h for jets measured at lower Reh. As Reh is increased, the larger width of the sub-range confirms the narrower dissipative range within the energy spectra. The variations of the dissipation rate (ɛ) of turbulent kinetic energy and the Kolmogorov (η) and Taylor (λ) microscales all obey similarity relationships, ɛh/Ub3∼Reh3, η/h ∼ Reh−3/4, and λ/h ∼ Reh−1/2. Finally, the underlying physical mechanisms related to discernible self-similar states and flow structures due to disparities in Reh and local Reynolds number is discussed.Ravinesh C. Deo, Graham J.
