Sustainable architecture in context : STS and design thinking

There has been little emphasis in STS scholarship to date on the design of the built environment. This paper attempts to address this oversight by examining alternative design practices in the growing field of sustainable architecture. We propose a geohistorical framework that includes three design dispositions—context-bound, context-free, and context-rich—and illustrate each with a prominent sust

Pathways of urban nature : diversity in the greening of the twenty-first century city

Nature is a central component of the twenty-first-century city. Beyond parks and open spaces, urban nature is implicated in strategies of economic development, climate change mitigation and adaptation, public art, biodiversity enhancement, local food production, health and livability, social justice, community identity, and more.1 This “pluralization” of urban nature has come about in the last four

The politics of urban experiments : realising radical change or reinforcing business as usual?

When Jean-Francois Mayet was elected mayor of the French city of Châteauroux in 2001, he inherited a mass transit system that was functional but under-used by residents. The city, located about halfway between Paris and Bordeaux, had collective aims that were similar to other medium-sized cities in Europe: to reduce the city’s ecological footprint while improving the local economy and fostering a

Match Theory : An overview

This paper introduces Match Theory, an Optimality-Theoretic approach to the syntax–phonology interface proposed by Selkirk (2011). The theory states that a family of Match constraints favor syntax–prosody isomorphism, but that these can be outranked by constraints on prosodic wellformedness and/or information structure, resulting in certain principled mismatches. We compare Match Theory to previou

Simultaneous immunohistochemistry and autoradiography of peptides and 5-hydroxytryptamine in bird retina

A method was developed for the simultaneous demonstration of two specific cellular constituents. Cryostat sections of formaldehyde fixed tissue from retinae treated with ((3)H)-5-hydroxytryptamine were subjected to immunohistochemistry and subsequent autoradiography. The method takes advantage of the very efficient and specific uptake mechanism that many types of neurons possess which makes it pos

Review of measures for improved energy efficiency in production-related processes in the aluminium industry – From electrolysis to recycling

The aluminium industry is facing a challenge in meeting the goal of halved greenhouse gas emissions by 2050, while the demand for aluminium is estimated to increase 2–3 times by the same year. Energy efficiency will play an important part in achieving the goal. The paper's aim was to investigate possible production-related energy efficiency measures in the aluminium industry. Mining of bauxite and

Some Early Christian Trees

In the wake of the current environmental crisis, scholars of late antique Christianity are beginning to study Christian attitudes towards the natural world. How did the early Christians relate to their environment? This article explores perceptions of trees, surveying the writings of Tertullian, Basil of Caesarea, and Sozomen the historian. What did an arboreal plant do, according to patristic aut

Towards a standard method for estimating fragmentation rates in emulsification experiments

The fragmentation rate function connects the fundamental drop breakup process with the resulting drop size distribution and is central to understanding or modeling emulsification processes. There is a large interest in being able to reliably measure it from an emulsification experiment, both for generating data for validating theoretical fragmentation rate function suggestions and as a tool for st

Pathophysiology of type 2 diabetes and the impact of altered metabolic interorgan crosstalk

Diabetes is a complex and multifactorial disease that affects millions of people worldwide, reducing the quality of life significantly, and results in grave consequences for our health care system. In type 2 diabetes (T2D), the lack of β-cell compensatory mechanisms overcoming peripherally developed insulin resistance is a paramount factor leading to disturbed blood glucose levels and lipid metabo

X-ray in-line holography and holotomography at the NanoMAX beamline

Coherent X-ray imaging techniques, such as in-line holography, exploit the high brilliance provided by diffraction-limited storage rings to perform imaging sensitive to the electron density through contrast due to the phase shift, rather than conventional attenuation contrast. Thus, coherent X-ray imaging techniques enable high-sensitivity and low-dose imaging, especially for low-atomic-number (Z)

Influence of variable oxygen concentration on the combustion derived release of radiocesium from boreal soil and peat

Radiocesium, 137Cs, is one of the most common and dispersed human-made radionuclides. Substantial stocks of 137Cs are stored in organic layers, like soils and peat, as a consequence of nuclear weapons fallout and accidental releases. As climate warming progresses these organic layers are subject to enhanced risks of wildfires, especially in the vast boreal biome of the northern hemisphere. Reemiss

Scaling up nature-based solutions for climate-change adaptation : Potential and benefits in three European cities

Many exemplary projects have demonstrated that Nature-based Solutions (NBS) can contribute to climate change adaptation, but now the challenge is to scale up their use. Setting realistic policy goals requires knowing the amount of different NBS types that can fit in the urban space and the benefits that can be expected. This research aims to assess the potential for a full-scale implementation of

Simulating crowding of urban green areas to manage access during lockdowns

During the COVID-19 emergency, cities around the world introduced measures to guarantee physical distancing that restricted access to urban parks and green areas, with potentially negative effects on citizens’ health and wellbeing. This study aims at providing insights to manage access to urban green space in physical distancing times, when the risk of crowding should be avoided. Using the city of

Does delivery service differentiation matter? Comparing rural to urban e-consumer satisfaction and retention

In the context of continuously growing e-commerce and the rising global count of e-consumers, e-retailers and logistics service providers need to differentiate and tailor their offerings to refine their operations and meet e- consumers’ needs. This study investigates how e-consumers’ residential-area type affects the satisfaction with delivery services and reuse intentions in relation to e-consume
