Creative small settlements. Culture-based solutions for local sustainable development.
Culture can play a fundamental role in fostering sustainable patterns of urban and regional development. This is the message of the Global Report âCulture for Sustainable Urban Developmentâ, which UNESCO has coordinated for the UN-HABITAT III Conference (Quito, October 2016). The Global Report shows that a promising culture-based vision of urban development is flourishing in different forms in several cities across the world. Even small and medium settlements located at the periphery of large cities or within their metropolitan areas, and normally associated with marginalisation or deprivation, have the potential to fully utilise their cultural resources, in both tangible (urban and architectural heritage, cultural infrastructure, etc.) and intangible form (skills, knowledge, competencies). However these small settlements, and their respective communities, require different analytical tools in order to understand their complexity and ad hoc policies to manage their assets in sustainable forms.
This research report aims to show ways to understand culture and creativity in small settlements, by collecting a series of international case studies that form the backbone of the chapter 10 of the UNESCO Global Report on urban-rural linkages and titled 'Culture as a tool to achieve harmonious territorial development'. This can allow a wider dissemination of the theoretical underpinnings and the comparative findings of a research conducted during 2015 and 2016 by several research units all over the world
A turbulence-driven model for heating and acceleration of the fast wind in coronal holes
A model is presented for generation of fast solar wind in coronal holes,
relying on heating that is dominated by turbulent dissipation of MHD
fluctuations transported upwards in the solar atmosphere. Scale-separated
transport equations include large-scale fields, transverse Alfvenic
fluctuations, and a small compressive dissipation due to parallel shears near
the transition region. The model accounts for proton temperature, density, wind
speed, and fluctuation amplitude as observed in remote sensing and in situ
satellite data.Comment: accepted for publication in ApJ
A Creative âNanotownâ. Framing Sustainable Development Scenarios with Local People in Calabria
During a two-year research programme from 2016 to 2018, scholars and students from diferent disciplinary backgrounds engaged with the local community of the town of Gagliato in Calabria, Italy, to co-produce future scenarios of local development. The aim was to enable a transition towards sustainability for a town afected by economic and demographic decline, like many other rural areas of southern Italy, but also be the protagonist of a promising annual summer science festival which had contributed to raising some expectations of change.
The research has been designed to enable transdisciplinary knowledge production in the urban feld that could matter for the local community and would ultimately produce a real, positive impact on peopleâs lives. Despite its broad premises to test innovative learning practices with participating students for an ideal future academia, its concrete outcomes have been deeply ingrained in the local community, becoming part of their discussions of daily life and even informing their political agenda
Efficacy Quotient of ESWL Piezolith Richard Wolf 3000 Machine in Patientswith Ureteral Stones in Dr. Cipto MangunkusumoNational Hospital 2008 - 2011
Extracorporeal shockwave lithotripsy (ESWL) is the most common method of ureteral stone management. Since 2008, RSCM has ben using ESWL piezolith 3000 richard wolf and efficacy quotient (EQ) value have not yet studied. The study aims was to determine the efficacy quotient (EQ) of ESWL using piezolith richard wolf 3000 machine for ureteral stone by analyzing free-stone rate with location of stones, number of stones, stone burden, stone opacity, obstruction and kidney function. This cross sectional study was carried out in January 2008-December 2011, with multivariate analytical study. Ninety five percent (n=113) of 119 patients were declared stone free after the first ESWL. EQ value was 0.89. Stone size was the correlated with stone free rate (p<0.05). It is concluded that ESWL procedure using richard wolf piezolith 3000 machine patients had better EQ and better stone-free rate than previous reports using similar machines
Oregano and its potential use as bioherbicide
Widespread use of synthetic herbicides in weed control could result in negative impact on human health and on the environment. Natural compounds could be successfully used as bioherbicides because they are potentially more environmental friendly and safe. Plants are an important source of active compounds. In particular, many species belonging to the Labiate family produce essential oils containing compounds that could act as natural herbicides. In this paper we report on preliminary studies about the effects on seed germination and plant growth of an oregano hybrid (Origanum vulgare L. ssp. virilidum Ă O. vulgare L. ssp. hirtum (Link) Iestwart). Experiments were done both in pots and in the field. Increasing amounts of chopped leaves and stems of oregano were added to the soil. In the pots, several weed species were sown, whereas naturally occurring infestation was evaluated in the field. In comparison with the control, a reduced number of weeds was observed where oregano biomass was added. The above-mentioned trend was more visible in the pots than in the field. The results suggest that the hybrid of oregano used in the trial could be an interesting source of natural compounds effective against weeds. Hence, further studies with this plant are likely to be successful
INTREPID Futures Initiative: Universities and Knowledge for Sustainable Urban Futures: as if inter and trans-disciplinarity mattered. 4th INTREPID REPORT
This London Workshop is meant to advance the agenda of âUniversities and Knowledge for Sustainable Urban Futures: as if ID and TD matteredâ, by helping to define the scope of the EU COST Action INTREPID contribution, and of the activities to be funded for 2017-2019. Intention statement: âTo contribute to the shaping of tomorrowâs universities & their urban curricula: as if inter and transdisciplinary ways of knowing actually matteredâ. For this purpose, the Workshop was a one-day gathering of experts and practitioners with diverse experience and disciplinary backgrounds. The report outlines the results obtained
Plasma turbulence and kinetic instabilities at ion scales in the expanding solar wind
The relationship between a decaying strong turbulence and kinetic instabilities in a slowly expanding plasma is investigated using two-dimensional (2D) hybrid expanding box simulations. We impose an initial ambient magnetic field perpendicular to the simulation box, and we start with a spectrum of large-scale, linearly polarized, random-phase Alfvénic fluctuations that have energy equipartition between kinetic and magnetic fluctuations and vanishing correlation between the two fields. A turbulent cascade rapidly develops; magnetic field fluctuations exhibit a power-law spectrum at large scales and a steeper spectrum at ion scales. The turbulent cascade leads to an overall anisotropic proton heating, protons are heated in the perpendicular direction, and, initially, also in the parallel direction. The imposed expansion leads to generation of a large parallel proton temperature anisotropy which is at later stages partly reduced by turbulence. The turbulent heating is not sufficient to overcome the expansion-driven perpendicular cooling and the system eventually drives the oblique firehose instability in a form of localized nonlinear wave packets which efficiently reduce the parallel temperature anisotropy. This work demonstrates that kinetic instabilities may coexist with strong plasma turbulence even in a constrained 2D regime
Scale dependence and cross-scale transfer of kinetic energy in compressible hydrodynamic turbulence at moderate Reynolds numbers
We investigate properties of the scale dependence and cross-scale transfer of
kinetic energy in compressible three-dimensional hydrodynamic turbulence, by
means of two direct numerical simulations of decaying turbulence with initial
Mach numbers M = 1/3 and M = 1, and with moderate Reynolds numbers, R_lambda ~
100. The turbulent dynamics is analyzed using compressible and incompressible
versions of the dynamic spectral transfer (ST) and the Karman-Howarth-Monin
(KHM) equations. We find that the nonlinear coupling leads to a flux of the
kinetic energy to small scales where it is dissipated; at the same time, the
reversible pressure-dilatation mechanism causes oscillatory exchanges between
the kinetic and internal energies with an average zero net energy transfer.
While the incompressible KHM and ST equations are not generally valid in the
simulations, their compressible counterparts are well satisfied and describe,
in a quantitatively similar way, the decay of the kinetic energy on large
scales, the cross-scale energy transfer/cascade, the pressure dilatation, and
the dissipation. There exists a simple relationship between the KHM and ST
results through the inverse proportionality between the wave vector k and the
spatial separation length l as k l ~ 3^1/2. For a given time the dissipation
and pressure-dilatation terms are strong on large scales in the KHM approach
whereas the ST terms become dominant on small scales; this is owing to the
complementary cumulative behavior of the two methods. The effect of pressure
dilatation is weak when averaged over a period of its oscillations and may lead
to a transfer of the kinetic energy from large to small scales without a net
exchange between the kinetic and internal energies. Our results suggest that
for large-enough systems there exists an inertial range for the kinetic energy
