The benefits of using sustainable building materials are linked not only to the adoption of manufacturing processes that entail reduced pollution, CO2 emissions and energy consumption, but also to the onset of improved performance in the building. In particular, hemp-lime composite shows low shrinkage and high thermal and acoustic insulating properties. However, this material also shows a great...

Although, considerable differences in root size in response to nitrogen (N) application among crop species and cultivars have been widely reported, there has been limited focus on the differences in root N uptake ability. In this study, two maize (Zea mays L.) hybrids, Zhenghong 311 (ZH 311, N-efficient) and Xianyu 508 (XY 508, N-inefficient), were used to compare differences in root N uptake a...

the aim of this study was to establish and optimise a simplified method of halved grain culture, in order to utilise it to evaluate the ability of isolated sinks (developing wheat grains) in sucrose uptake and conversion (defined by sink strength) under unlimited source conditions. both sucrose uptake and starch synthesis increased linearly over the incubation periods used in this study. a ...

Eutrophication has become a serious environmental problem because of the excessive amounts nitrogen and phosphorus in water. Aquaculture waste is one drivers eutrophication. Seaweed known for its ability to remove nutrients from In Indonesia, research about efficiency seaweed decreasing nutrient concentration wastewater still rare. This article reviewed use as an adsorbent removal. review aims ...

The water uptake by roots of plants is examined for an ideal situation, with an approximation that resembles plants growing in pots, meaning that the total soil volume is fixed. We propose a coupled water uptake-root growth model. A one-dimensional model for water flux and water uptake by a root system growing uniformly distributed in the soil is presented, and the Van Genuchten model for the t...

The Eastern oyster, Crassostrea virginica, lives in shallow coastal waters and experiences many different environmental extremes including hypoxia, hypercapnia and air exposure and many oysters are infected with the protozoan parasite Perkinsus marinus. The effects of these conditions on oyster metabolism, as measured by oxygen uptake, were investigated. Mild hypercapnia had no effect on the ab...

The hydrophilic property of cellulose is a key limiting factor for its wide application. Here, a novel solution impregnation pathway was developed to increase the hydrophobic properties of cellulose. When compared with the regenerated cellulose (RC), the composite films showed a decrease in water uptake ability towards water vapor, and an increase of the water contact angle from 29° to 65° with...
