Developments and contributions in the study of La Rioja dinosaur footprints (Spain)
2020
In this paper the study of dinosaur tracks of La Rioja, which began in 1970, is presented as an example of knowledge development, achievements, and events occurring around a paleontological resource having strong media impact. Fieldwork, research, and dissemination since the publication of the first scientific works have been accompanied by activities to protect sites and consider them as natural and cultural heritage. Finally it is shown how a paleontological resource has also led to the development of the tourist infrastructure in the area
Growth phase-dependent regulation of nuoA-N expression in Escherichia coli K-12 by the Fis protein: upstream binding sites and bioenergetic significa…
2000
The expression of the nuoA-N operon of Escherichia coli K-12, which encodes the proton-pumping NADH dehydrogenase I is modulated by growth phase-dependent regulation. Under respiratory growth conditions, expression was stimulated in early exponential, and to a lesser extent in late exponential and stationary growth phases. The stimulation in the early exponential growth phase was not observed in fis mutants, which are deficient for the growth phase-responsive regulator Fis. Neither the alternative sigma factor RpoS nor the integration host factor (IHF) are involved in growth phase-dependent regulation of this operon. When incubated with nuo promoter DNA, isolated Fis protein formed three re…
Requirement of the Lactobacillus casei MaeKR two-component system for L-malic acid utilization via a malic enzyme pathway.
2009
ABSTRACTLactobacillus caseican metabolizel-malic acid via malolactic enzyme (malolactic fermentation [MLF]) or malic enzyme (ME). Whereas utilization ofl-malic acid via MLF does not support growth, the ME pathway enablesL. caseito grow onl-malic acid. In this work, we have identified in the genomes ofL. caseistrains BL23 and ATCC 334 a cluster consisting of two diverging operons,maePEandmaeKR, encoding a putative malate transporter (maeP), an ME (maeE), and a two-component (TC) system belonging to the citrate family (maeKandmaeR). Homologous clusters were identified inEnterococcus faecalis,Streptococcus agalactiae,Streptococcus pyogenes, andStreptococcus uberis. Our results show that ME is …
Synthetic environmental appraisal of waste management system: an application to the Sicilian region
2004
This paper addresses the problem of synthetically evaluating the environmental performances of urban solid waste systems. This, in fact, represents a crucial point in the management process of complex systems that local administrations are called to cope with, in order to provide decisions about policy options that involve different issues characterising the quality of life of people. Suitable methods of evaluation are clearly required for this aim. This work introduces the dashboard of sustainability and the ecological footprint approaches as aggregate indicators of the performances of solid waste management systems. The methods have been selected due to their intrinsic simplicities, provi…
Identification of Explanatory Variables in Possession of the Ball in High-Performance Women’s Football
2021
[Abstrac] Women’s football is a phenomenon that is experiencing an unstoppable increase in recent years. The objective of this study was to analyze how ball possessions are performed in highperformance women’s football. For this, the 52 matches played by all the national teams participating in the Women’s World Cup 2015 were analyzed. A total of 3740 ball possessions were examined. Using the “move outcome” variable as a reference criterion, a statistically significant relationship was found between possessions that ended in success and possessions that have failed. Specifically, the successful possessions were those that were made in the offensive zone, with a clear intention to progress to…
Behind the Digital
2019
Fraschini gives a critical and interrogative view to digital design. He righly dwells much upon the tactile aspect of architecture. His reflections are grounded on Mario Carpo studies and very importantly he traces the idea of footprint as ground stone for architectural design.
Rapid evaluation of ammonium in different rain events minimizing needed volume by a cost-effective and sustainable PDMS supported solid sensor.
2020
Abstract The presence of ammonium ion in rainwater is due to atmospheric processes which involve its scavenging from gas phase and particulate matter. The fractionated samplings of rainwater can provide information about these processes and their potential sources. However, only a low sample volume may be available, which constrained the analysis in general and more particularly in situ mode. For minimizing this limitation, this work proposes a polydimethylsiloxane (PDMS)-salicylate sensor that produces a color change. The embedding of solid reagents into PDMS was optimized. Good analytical characteristics (analysis time of 10 min, sample volume of 500 μL, limit of detection 0.03 μgmL−1) we…
Il Piede nella Malattia Diabetica
2005
Foot ulcers and amputations are a major cause of morbidity, disability, as well as emotional and physical costs for people with diabetes. Distal symmetric polyneuropathy is one of the most important predictors of diabetic foot conditions. The development of neuropathy can be delayed significantly by maintaining glycemic levels to as near normal as possible
A Holistic Vision of Smart Cities: An Opportunity for a Big Change
2016
The depletion of energy resources on the one hand, and the population growth on the other, forced the society at all levels (local, national and international) to turn its attention to the identification of new forms of protection of the environment and the waste reduction for a new eco-sustainable way of living. The process of massive urbanization already in place, exacerbated by the movement of large masses of people in search of a more human form of life, is putting severely under test the livability within our cities, bringing out the inefficiency of existing management and organization models. Daisaku Ikeda said: “Certainly, the density of urban populations means that problems are conc…
Cities facing the Wild
2021
Untamed ecosystems and plots of wild nature increasingly constitute large parts of contemporary urban spaces. They are often the unbidden result of a long-standing lack of maintenance as well as of the uncontrolled flourishing of weeds produced by the pesticide absolute ban. But they are also something more. Many recently implemented urban open spaces deal with wild nature to solve some of the most urgent tasks of the contemporary cities: reclaiming areas fallen into disuse, designing sustainable infrastructures, revitalizing valuable public spaces, enhancing the ecological footprint of new developments, suggesting new practices and social ritual, reducing management costs, fighting climate…
