Model of Continuous Cheese Whey Fermentation by Candida Pseudotropicalis [PDF]

open access: yes, 2009
The utilization of cheese whey as a fermentation substrate to produce bio-ethanol is an effort to supply bio-ethanol demand as a renewable energy. Like other process systems, modeling is also required for fermentation process design, optimization and ...

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

open access: yesAdvanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Hydraulic factors limiting the use of subirrigation in fine textured soils : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Philosophy in Agricultural Engineering at Massey University [PDF]

open access: yes, 1996
Subirrigation is a method of supplying water directly to the plant root zone under the ground surface by means of subsurfce drains which are also used to remove excess water from the root zone. Subsurface drainage systems are used to maintain appropriate

Optimal design of water distribution systems based on entropy and topology [PDF]

open access: yes, 2014
A new multi-objective evolutionary optimization approach for joint topology and pipe size design of water distribution systems is presented. The algorithm proposed considers simultaneously the adequacy of flow and pressure at the demand nodes; the ...

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

The information and computing complex “ANGARA-VS” for end-to-end modeling of water supply systems when developing development schemes, scheduling modes, and dispatching management

open access: yesMATEC Web of Conferences, 2018
The paper presents a brief description of the problems of making technological decisions to manage the development and functioning of water supply networks in conditions of territorial, structural, and temporal disconnection of the decision-making ...

Taming the Floods: Using an Intellectual History of Chinese Hydraulic Thought to Address Contemporary Issues in China’s Water Governance [PDF]

open access: yes, 2018
China’s current hydraulic systems are in a state of atrophy, caused by sustained damage over centuries to infrastructure that has changed very little. Added to an already weak infrastructure is a relatively new crisis of water scarcity, which is forcing ...

3D Printed Multimaterial Microfluidic Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

THE SIMULATION OF HYDRAULIC SYSTEMS

open access: yesIFAC Proceedings Volumes, 1980
Abstract This paper describes progress towards a general purpose simulation language for hydraulic systems. The aim of the language is to allow engineers with no formal skill in computer programming or mathematical modelling to examine the dynamic or steady state conditions in systems at the design stage.
