Unlike other industries, overall efficiency of construction projects has been growing minimally which directly causes cost overruns of projects. Though reducing idle time and increasing operational efficiency of construction equipment could result in significant cost saving, there is lack of practical knowledge of adjusting operational efficiency and integrating cost and...
Ethanol production from lignocellulosic feedstock has been under intense scrutiny as a transportation fuel due to its potential to address concerns of increasing energy consumption, limited fossil energy resources, climate changes due to greenhouse gas emissions from fossil fuels, and especially use of non-food biomaterials, which address the biggest limitation...
Background, aim and scope: The aim of this study was to perform a well-to-pump life cycle assessment (LCA) to investigate the overall net energy balance and environmental impact of bioethanol production using Tall Fescue grass straw as feedstock. The energy requirements and green house gas (GHG) emissions were compared to...
Background: During cellulosic ethanol production, cellulose hydrolysis is achieved by synergistic action of cellulase
enzyme complex consisting of multiple enzymes with different mode of actions. Enzymatic hydrolysis of cellulose is
one of the bottlenecks in the commercialization of the process due to low hydrolysis rates and high cost of
enzymes....

Poly-3-hydroxybutyrate (PHB) is a renewable, biodegradable biopolymer that has
shown great promise to offset the use of hydrocarbon-derived plastics. The genes
encoding the bacterial PHB production pathway have been engineered into several
higher order plant species providing an opportunity to produce PHB as a
co-product on an industrial, agricultural scale....
Bioethanol produced from the lignocellulosic feedstock is a potential alternative to fossil fuels in transportation sector and can help in reducing environmental burdens. Straw produced from perennial ryegrass (PR) and wheat is a non-food, cellulosic biomass resource available in abundance in the Pacific Northwest U.S. The aim of this study...
Desalination stands for removing salt from saline water, and produce freshwater. Desalination technologies have been envisioned as a potential solution for freshwater production from oceans as an immense source of water acquiring 97% earth’s water, and 75% of earth’s surface. However, one third of world’s population face water scarcity every...
Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...
