Abstract Abandonment of agricultural fields triggers the ecosystem recovery in process referred to as secondary succession. The objective this study was find impact succession during 12 years lasting abandonment with loamy sand and sandy loam soils on soil properties, namely organic carbon content, pH, water ethanol sorptivity, hydraulic conductivity, drop penetration time (WDPT), repellency in...

We report a simple fast, practical and effective method for the replication of the complex venation patterns of natural leaves into PDMSwith accuracy down to a lateral size of 500 nm. Optimising the amount of crosslinker enabled the replication and sealing of the microvascular structures to yield enclosed microfluidic networks. The use of plant leaves as templates for soft lithography was demon...

Lightweight concrete has a density lower than conventional concrete, which ranges between 1,400-1,800 Kg/cm3. The use of lightweight as more sustainable construction material continues to be developed reduce the weight building. Fly ash residue from coal combustion high SiO2 content cement substitute. Bottom with light can also used substitute for fine aggregate. Sorptivity test in aims determi...

This article presents the long-term mechanical properties of a novel cement composite, no-aggregate concrete (NAC), containing 80% low-calcium (class F) fly ash (F-FA) and 20% ordinary Portland (OPC) without aggregates. The study investigates effect adding polypropylene fibers (PPFs) in varying volume fractions to NAC by conducting compressive, splitting tensile, flexural, bond strength, sorpti...

The objective of this paper is to report the cumulative effects of cropping system intensification on the near surface soil physical properties (surface one inch of soil) within the Colorado dryland agroecoystem project, which has been in existence since 1986. Intensifying cropping systems from wheat-fallow to wheat-com-fallow to continuous cropping, increased crop residue return to the soil. R...
