Current technological shortcomings limit the economic viability of capturing and utilizing small sources of methane. The development of a reactor to overcome these limitations would unlock economic opportunity and incentivize reduced methane emissions. A microfluidic bioreactor containing immobilized methanotrophs has the potential to overcome these limitations by profitably converting small...
Lower production costs are a common goal of many manufacturers as part of their continuous improvement strategies. A large portion of production costs for manufacturers is the machining of metals to form components. Metal machining is accompanied by friction and heat which is dealt with using metalworking fluids such as...
Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated...
Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...
Phoma menthae Strasser causes black lesions and cankers on
stems and rhizomes of Mentha piperita L. The fungus was isolated
from infected rhizomes and stems.
The optimum temperature for growth of the fungus in culture
was between 20-25°C; little growth occurred at 5°C, and no growth
occurred at 35.5°C.
Among...
A vital safety concern in the analysis of nuclear power reactors
is the thermal hydraulic behavior of the reactor coolant system
under steady state and transient conditions. The goal of this
study has been to develop an appropriate model for the U-tube type
steam generators in a typical pressurized water...
The present thesis is about the electric power distribution system
for the city of Mecca, in Saudi Arabia. The distribution system
of Mecca started suddenly, grew haphazardly and developed quickly
with a load factor as high as 38%. Lack of planning, records and
training plus insufficient experience of management evolved...
In previous years, at Corvallis, yields of bush snap beans
varied among planting dates. In order to obtain additional information
on the effect of planting dates on the growth, development and
yield of snap beans, four field plantings and two greenhouse plantings
of the variety O.S.U. 2051 were made.
Results...
The goal of this study is the modeling of a postulated break
of the steam line at the containment penetration of the Trojan
Nuclear Plant which is owned and operated by Portland General
Electric. To perform this modeling, the RETRAN computer code
package was utilized. RETRAN is designed to provide...
