Missing water from the Qiangtang Basin on the Tibetan Plateau

David Andrew Barry

The Qiangtang Basin is a large endorheic basin in the inner part of the Tibetan Plateau and has been thought to be a dry region in contrast with its wet surrounding outer region that feeds all the major Asian rivers. Combining surface hydrological data wit ...

Synthesis of minimum energy adaptive structures

Gennaro Senatore

This paper presents the formulation of a new methodology to design adaptive structures. This design method synthesises structural configurations that are optimum hybrids between a passive and an active structure. An optimisation scheme searches for an opti ...

Model of crop growth, water flow, and solute transport in layered soil

David Andrew Barry, Jiancheng Yang, Jian Yang

Agro-ecohydrological models are essential for managing scarce water resources and ensuring crop productivity. Here, a one-dimensional agro-ecohydrological model, LAWSTAC, capable of simulating water and solute transport in layered soil coupled with crop gr ...

Atomistic Simulations of The Structure of Calcium Silicate Hydrates: Interlayer Positions, Water Content And A General Structural Brick Model

Aslam Kunhi Mohamed

Portland cement has been in use by human civilization for over a century. Yet, we do not fully understand its hydration reaction mechanisms due to the complexity of the system and its continued reaction over time making it hard to study it experimentally. ...

Molecular-level characterization of curved water interfaces with sum frequency and second harmonic scattering

Nikolay Smolentsev

Aqueous interfaces are omnipresent in nature. Some of them are visible: droplets in clouds, aerosols, and surfaces of oceans, lakes, and rivers. Many more surfaces are hidden: water in contact with cell membranes, proteins, and the surface of droplets in e ...

Anisotropic Volumetric Response of Shales upon Suction Changes

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Anisotropic fabric and volumetric response to suction changes represent two main features of shales, which are involved in several engineering applications. However, a comprehensive understanding of the interaction between these two aspects is still missin ...

Water Saving and Energy Reduction through Pressure Management in Urban Water Distribution Networks

Koen Blanckaert

Water shortages and climate change are worldwide issues. Reduction in water leakage in distribution networks as well as the associated energy saving and environmental impacts have recently received increased attention by scientists and water industries. Pr ...

Water use and quality in life cycle assessment : identifying good practices and developing operational spatial approaches

Anna Kounina Massé

Pressure on freshwater resources is increasingly covered by methodological developments addressing freshwater use in the field of Life Cycle Assessment (LCA). These developments ultimately lead to the publication of the ISO 14046 standard to define the pri ...

From the Cover: Water-controlled wealth of nations

Andrea Rinaldo, Amos Maritan, Samir Suweis

Population growth is in general constrained by food production, which in turn depends on the access to water resources. At a country level, some populations use more water than they control because of their ability to import food and the virtual water requ ...

Evolution of the global virtual water trade network

Andrea Rinaldo

Global freshwater resources are under increasing pressure from economic development, population growth, and climate change. The international trade of water-intensive products (e.g., agricultural commodities) or virtual water trade has been suggested as a ...

Temporal dynamics of blue and green virtual water trade networks

Andrea Rinaldo

Global food security increasingly relies on the trade of food commodities. Freshwater resources are essential to agricultural production and are thus embodied in the trade of food commodities, referred to as "virtual water trade." Agricultural production p ...

Water for food: The global virtual water trade network

Andrea Rinaldo, Samir Suweis

We present a novel conceptual framework and methodology for studying virtual water trade. We utilize complex network theory to analyze the structure of the global virtual water trade associated with the international food trade. In the global virtual water ...

Structure and Controls of the Global Virtual Water Trade Network

Andrea Rinaldo, Samir Suweis

Recurrent or ephemeral water shortages are a crucial global challenge, in particular because of their impacts on food production. The global character of this challenge is reflected in the trade among nations of virtual water, i.e. the amount of water used ...

Water: A key resource in energy production

Christoph Frei

Water and energy are the key resources required for both economic and population growth, and yet both are increasingly scarce. The distribution of water takes large amounts of energy, while the production of energy requires large amounts of water in proces ...

Fabrication of Dendritic Gold Nanoparticles by Use of an Ionic Polymer Template

Paul Joseph Dyson, Zhaofu Fei, Dongbin Zhao

A facile method for the fabrication of dendritic gold nanoparticles (NPs) by use of an ionic polymer template has been developed. In situ generation of an imidazolium-based (cationic) polymer, poly[1-methyl-3-(4-vinylbenzyl)imidazolium], with AuCl4- counte ...
