Aqueous-Based Extrusion Fabrication of Ceramics on Demand [PDF]

open access: yes, 2007
Aqueous-Based Extrusion Fabrication is an additive manufacturing technique that extrudes ceramic slurries of high solids loading layer by layer for part fabrication. The material reservoir in a previously developed system has been modified to allow for

TECHNIQUES TO MONITOR DRYING STRESSES AND DIMENSIONAL CHANGES IN TIMBER FROM PLANTATION-GROWN EUCALYPTS FOR KILN SCHEDULE DEVELOPMENT AND KILN CONTROL

open access: yesMaderas: Ciencia y TecnologĂ­a, 2002
Drying tests were conducted with timber from 13 year-old plantation-grown Eucalyptus nitens and E. globulus, to determine shrinkage and drying degrade of tangential- and radial-sawn boards.

Experimental investigation on the influence of drying on the seismic performance of three-story RC buildings

open access: yesDevelopments in the Built Environment
The drying of concrete has been recognized as a key phenomenon in the deterioration of concrete structures. Nevertheless, the complex conditions of real RC structures may lead to unforeseen responses observed from existing laboratory experiments on RC ...

Characteristics of Timbers Dried Using Kiln Drying and Radio Frequency-Vacuum Drying Systems

open access: yesMATEC Web of Conferences, 2017
Heavy hardwoods are difficult-to-dry timbers as they are prone to checking and internal stresses when dried using a conventional kiln drying system. These timbers are usually dried naturally to reach 15% to 19% moisture content with an acceptable defects.

The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]

open access: yes, 1996
Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...
