Understanding Emergent Urbanism The Case of Tirana, Albania
he canonical architectural studies have handed us the idea that city is the result of a series of top-down procedures - and related documentary materials - which depict a rigid and hardly con- testable direction of development of our urban tissues. Looking at the different regulatory plans throughout which contempo- rary cities have been developed, it is quite difficult to perceive the human component of such spaces, leaving us to wander in a series of linear relations where the final form is predetermined by external judging eyes. But if we look at the city as a living being, characterized from the different complex entities that in- habit it and interact among each others, is it possible to bring the real city - or as the author underlines, the city of everyday life - close to conventional planning?

Low hydrogen sulphide and chronic kidney disease: A dangerous liaison
Hydrogen sulphide, H(2)S, is a gaseous compound involved in a number of biological responses, e.g. blood pressure, vascular function and energy metabolism. In particular, H(2)S is able to lower blood pressure, protect from injury in models of ischaemia-reperfusion and induce a hypometabolic state. In chronic kidney disease (CKD), low plasma hydrogen sulphide levels have been established in humans and in animal models. The enzymes involved in its production are cystathionine β-synthase, cystathionine γ-lyase and 3-mercaptopyruvate sulphurtransferase. The mechanisms for H(2)S decrease in CKD are related to the reduced gene expression (demonstrated in uraemic patient blood cells) and decreased protein levels (in tissues such as liver, kidney, brain in a CKD rat model). In the present Nephrol Dial Transplant issue, in fact, Aminzadeh and Vaziri document that the alterations in this pathway complicate the uraemic state and are linked to CKD progression. They furnish a time frame in CKD and record enzyme tissue distribution. It remains to be established if low H(2)S is causally linked to CKD progression and if interventions aimed to restore the status quo ante are able to modify this picture.Hydrogen sulphide, H2S, is a gaseous compound involved in a number of biological responses, e.g. blood pressure, vascular function and energy metabolism.

Street-level workers, managers and institutional tensions: a comparative ethnography of healthcare practices of in/exclusion in three Italian public organisations
Este artículo está sujeto a una licencia CC BY 4.0Public organisations are fundamental actors in migrant incorporation processes, as they are in charge of assessing migrants’ entitlement and providing access to welfare services. While a lot has been written on the individual determinants of street-level decisions, the role of organisational and institutional factors in shaping implementation practices has received little attention so far. By linking the street-level bureaucracy approach and the neo-institutionalist perspective in organisational analysis, this article investigates how public organisations mediate migrant incorporation processes in the field of healthcare. Drawing on a comparative ethnographic study of three public health organisations in an Italian region, the paper suggests that, in times of institutional tensions, managers’ priorities and framings of the issue, the ways they respond to decision-makers’ goals and allocate resources for implementing them, orient - and lead to variation in - street-level healthcare practices of in/exclusion for migrants with irregular status.The author acknowledges support of the publication fee by Erasmus University and the CSIC Open Access Publication Support Initiative through its Unit of Information Resources for Research (URICI)Peer reviewe
MPM hydro-mechanical modelling of flows impacting rigid walls
The study on impact mechanisms of flow-like landslides against structures is still an open issue in the scientific literature. Many researchers have employed so far either experiments or numerical methods, but the evaluation of the impact forces on mitigation obstacles remains difficult especially if the solid-fluid interaction within the flow is considered. This study shows how advanced numerical tools, such as Material Point Method, may be used in simulating those complex processes. The simulations are carried out for two well documented laboratory tests: a dry granular flow impacting a rigid wall under different geometries and testing conditions in a small-scaled flume and a saturated flow with complex propagation pattern in a centrifuge apparatus. The numerical modelling is validated against the observations and then used to explore the response of different flows impacting rigid structures in other conditions than in the experiments. The soil-fluid interaction influences the type of impact mechanism, the kinematics of the flow, and the space-time trend of the impact pressure against the structure.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

How rapidly do neutron stars spin at birth? Constaints from archival X-ray observations of extragalactic supernovae
Traditionally, studies aimed at inferring the distribution of birth periods of neutron stars are based on radio surveys. Here we propose an independent method to constrain the pulsar spin periods at birth based on their X-ray luminosities. In particular, the observed luminosity distribution of supernovae (SNe) poses a constraint on the initial rotational energy of the embedded pulsars, via the correlation found for radio pulsars, and under the assumption that this relation continues to hold beyond the observed range. We have extracted X-ray luminosities (or limits) for a large sample of historical SNe observed with Chandra, XMM and Swift, which have been firmly classified as core-collapse SNe. We have then compared these observational limits with the results of Monte Carlo simulations of the pulsar X-ray luminosity distribution for a range of values of the birth parameters. We find that a pulsar population dominated by millisecond periods at birth is ruled out by the data
Paleokarstic fills in Iglesiente (Sardinia Italy) sedimentary processes and age
The Mount S. Giovanni caves developed mostly during Paleozoic and Mesozoic in Cambrian limestones (Gonnesa formation) locally mineralized. Their infilling, of economic interest, took place during or nearly after the volcanic Cenozoic phase. The material derives from the removal of important pedogenetic cover, with episodes of clays masses redeposition and phases of wall collapses and of concretioning. -from Author
Bara and Viala, or Virtue Rewarded: The Memorialization of Two Child Martyrs of the French Revolution
This article explores the commemoration of republican child martyrs Joseph Bara and Joseph-Agricol Viala, in Year II (1793–4), during the French Revolution. It compares the official interpretation of their deaths with the subsequent appropriation of this narrative in wider culture. The article argues that leading revolutionaries—notably Robespierre, Barère and David—utilized the heroic deaths of children specifically for their associations with natural virtue and innocence, setting the tone for a new model of republican morality. It then demonstrates that the state’s narrative was widely circulated, yet appropriated and commodified, using popular prints and theatre as case studies. This article thus demonstrates the limits of official control over French Revolutionary culture and traces the fragmented roots of what would become a revived memory cult in the Third Republic.Copyright © 2021 Oxford University Press.

Feasibility of green mussel, Perna viridis farming in Marudu Bay, Malaysia
AbstractBivalve aquaculture is an important source of affordable animal protein for coastal community. The success and sustainability of this industry is highly influenced by the suitability of the environment in which it is carried out. Present study was carried out to evaluate the feasibility of green mussel (Perna viridis) farming in Marudu Bay. The site suitability for green mussel farming was evaluated based on biophysical parameters and food availability. The in situ environmental parameters, phytoplankton abundance and composition were collected from 10 sampling stations on monthly interval from May 2014 to April 2015. The results showed that the environmental parameters and food availability in most of the sampling stations were suitable for green mussel. However, the presence of phytoplankton taxa (Chaetoceraceae) which are unfavorable by green mussel in most of the stations located at the bay pocket make those areas less recommended for green mussel farming. In contrast, stations located on the mouth of the bay exhibited high site suitability rating points and hence are highly recommended for cultivation of green mussel
