Identification of leachate infiltration and its flow pathway in landfill by means of electrical resistivity tomography (ERT)

open access: yesEnvironmental Monitoring and Assessment, 2020
Sanitary landfills are a well-planned engineering work for final disposal of municipal solid waste in order to minimize the environmental impacts in soil and groundwater. Therefore, several control systems are installed such as liners and leachate and biogas collectors.

Lobbying and Political Risk Disclosure: Do Socially Responsible Firms Voluntarily Disclose More?

open access: yesBritish Journal of Management, EarlyView.
Abstract Drawing on theories of strategic communication, legitimacy, impression management and moral capital, this study investigates whether firms use political risk disclosure to offset negative perceptions associated with corporate lobbying. Using a sample of 10,120 observations from 1362 US firms between 2002 and 2018, we find that firms with ...

PRECARIZED AGEING‐IN‐PERIFERIA: Low‐Income Older Adults in a Transforming Neighbourhood

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article we investigate how intersecting forms of precarity shape the everyday practices of ageing‐in‐place developed by low‐income older adults in Via Milano, a historically segregated yet rapidly transforming neighbourhood in Brescia, northern Italy. We draw on qualitative and ethnographic research to examine how diverse urban changes—

Assessing the Vulnerability of an Inuit Archaeological Site in a Changing Periglacial Environment: A Novel Multimethod Geophysical Approach in Arctic Geoarchaeology

open access: yesArchaeometry, EarlyView.
ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

A flowmeter for measuring the dispersed phase velocity in multiphase flow with non-uniform velocity profile

open access: yes, 2008
This study aims to introduce a new technique to measure the velocity distribution of the dispersed component of a vertical, upward, water continuous two-phase pipe flow. Here, it is proposed that measurements of the variation in the local conductance

Using Electrical Resistivity Tomography (ERT) to assess the effectiveness of capping in old unlined landfills

open access: yes, 2022
Abstract Engineered capping systems are efficient tools for the safety concept for landfills and contaminated land, consisting of multilayer barriers installed at the top of the deposited waste, even years after its closure. The efficiency of such systems is closely associated with avoiding rainwater infiltration into the waste body, a ...

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...
