Billboards. Two projects by Maurizio Montagna
No full textArchitecture, 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
Iron status in patients with plasmodium falciparum malaria and anaemia in Mulago hospital
No full textA dissertation submitted in partial fulfillment of the requirements for the award of the degree of Master of Medicine in Internal Medicine of Makerere UniversityMalaria is an important cause of morbidity and mortality in Uganda. It is associated with a wide range of complications including severe anaemia especially in children. Anaemia impairs motor and cognitive development in children and is a common cause of hospital admissions, blood transfusions and deaths. Blood transfusions are not only costly to the health system but also the risk of transmission of HIV to the recipients in countries like Uganda where HIV is highly prevalent. The pathogenesis of malaria-associated anaemia is complex, multi-factorial, and not clearly understood. Studies have shown that pre-existing iron deficiency aggravates the severity of malarial anaemia. However, there are concerns that iron supplementation leads to formation of more young red blood cells, which are more prone to plasmodium falciparum infection and that circulating iron provided the developing parasites with the iron they require to grow. These concerns are sometimes an impediment to implementation of iron supplementation programmes. Despite these concerns iron supplementation is recommended in malarious areas where iron deficiency is prevalent. Unfortunately, in Uganda the magnitude of iron deficiency in patients with malaria and anaemia is not known. Objectives: To assess the iron status in patients with malaria and anaemia attending Mulago hospital assessment centre clinic. Methods: Study setting: Mulago Hospital Assessment Centre. Design: Descriptive cross sectional study with an analytical component. Subjects: Patients with plasmodium falciparum and anaemia aged 6 months to 12 years. For this analysis anaemia was taken as haemoglobin level of 10g/dl or less. Measurements: Patients were recruited from the Mulago hospital assessment centre by systematic random sampling. A face-to-face interview using a standardized questionnaire on symptoms related to malaria and anaemia was administered and a complete physical examination perfumed. A full blood count, peripheral blood film and parasite density was done for each patient; serum ferritin, and C - reactive protein, was also determined. Each patient’s stool was examined for hookworm ova and occult blood. Other parasites were documented for patient management. Study results: The prevalence of iron deficiency found in this population was 40% according to serum ferritin concentrations as a measure of body iron stores. Seventy two percent of the children had a hypochromic microcytic type of anaemia. The mean MCV, MCH and MCHC respectively were 74.6fl, 24.5pg, and 33.1g/dl. Mean HB was 7.8± 2g/dl. Children with previous episodes of malaria had a lower MCV. All children had inflammation (CRP>6mg/l) and there was a positive correlation between CRP and serum ferritin (p=0.047). No correlation was found between parasite density and iron status of the children. Hookworm infestation was detected in only 4.5% of the children. Conclusion and Recommendation: The study shows that a significant proportion of children with malaria-associated anaemia attending Mulago Hospital Assessment Centre have iron deficiency. The high prevalence of hypochromic microcytes could be due to IDA. More reliable criteria for defining iron deficiency such as haematological response to iron therapy are needed to ascertain the exact prevalence. Nevertheless given the large number of children with evidence of depleted iron stores, iron supplementation should be considered in children with malaria associated anaemia, after anti-malarial therapy, especially in areas where no facilities exist for the specific diagnosis of anaemia
Pharmaceuticals in the Built and Natural Water Environment of the United States
No full textabstract: 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
No full textL'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

No full textA 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.
