Effect Of Seeding Materials And Mixing Strength On Struvite Precipitation, Jun Wang, Joel Gerard Burken, Xiaoqi Zhang Jan 2006

Effect Of Seeding Materials And Mixing Strength On Struvite Precipitation, Jun Wang, Joel Gerard Burken, Xiaoqi Zhang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Struvite Precipitation Has Increasing Interest as a Technology for Removing and Recovering Phosphorus from Wastewater Streams. Many Chemical Factors Have Been Studied, Such as Optimum PH Values and Component-Ion Molar Ratios, Yet, Understanding of Physical Aspects is Lacking. Two Physical Parameters Were Tested: (1) Seeding Material Addition and (2) Mixing. Objectives Were to Evaluate Three Seeding Materials and to Optimize Mixing Conditions for Struvite-Crystal Precipitation, Growth, and Subsequent Sedimentation. Results Confirm that Mixing Strength and Proper Seeding Materials Increase Crystal Size and Improve Settleability. for Unseeded Solutions, Optimum Phosphorus Removal Was Achieved at a Mixing Strength of G = 76 …

Revised Asce Specification For The Design Of Cold-Formed Stainless Steel Structural Members, Shin Hua Lin, Wei Wen Yu, Theodore V. Galambos, Edward Wang Aug 2005

Revised Asce Specification For The Design Of Cold-Formed Stainless Steel Structural Members, Shin Hua Lin, Wei Wen Yu, Theodore V. Galambos, Edward Wang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Since the publication of the first edition of the AISI specification for the design of light gage cold-formed stainless steel structural members in 1968 [Specification for the design of light gage cold-formed stainless steel structural members. 1968 ed. American Iron and Steel Institute (AISI); 1968], cold-formed stainless-steel members have been increasingly used in building construction and other structural applications due to their superior corrosion resistance, ease of maintenance, pleasing appearance, and high strength. in 1990, the first ASCE standard, ANSI/ASCE-8-90 [Specification for the design of cold-formed stainless steel structural members (ANSI/ASCE 8-90). American Society of Civil Engineers (ASCE); 1991], was …

Guiding Growth: A Survey Of Tax Incentives, New England Environmental Finance Center, Muskie School Of Public Service Jan 2003

Guiding Growth: A Survey Of Tax Incentives, New England Environmental Finance Center, Muskie School Of Public Service

Legislation

Current development patterns and increased tax pressures in local municipalities combine to harm both Maine’s natural resources and its quality of life. Previous initiatives such as the implementation of zoning laws did not fully result in the desired outcomes. Zoning laws were often too flexible and often did not resist market and political pressures to change zoning regulations to allow development with possible economic growth. A sound taxation system or fee structure may be the solution to slow down development in natural areas and direct it towards areas appropriate for growth.

To protect Maine’s natural resources more successfully from future …

University Of Missouri-Rolla Research On Cold-Formed Steel Structures, Wei Wen Yu, Roger A. Laboube Jan 1997

University Of Missouri-Rolla Research On Cold-Formed Steel Structures, Wei Wen Yu, Roger A. Laboube

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

During the past 27 years, numerous research projects have been conducted at the University of Missouri-Rolla (UMR) under the sponsorships of the American Iron and Steel Institute, National Science Foundation, American Society of Civil Engineers, Metal Building Manufacturers Association, Steel Deck Institute, Metal/Lath Steel Framing Association, Chromium Center, Nickel Development Institute, and several steel companies located in the USA, Canada, and South Africa. The purpose of these investigations has been to study the structural strength of cold-formed steel members, connections, and structural systems. Some of the research findings have been used in the development of the AISI Specification for the …

Asce Lrfd Method For Stainless Steel Structures, Shin Hua Lin, Wei-Wen Yu, Theodore V. Galambos Jan 1992

Asce Lrfd Method For Stainless Steel Structures, Shin Hua Lin, Wei-Wen Yu, Theodore V. Galambos

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In recent years, probability-based load-and-resistance-factor-design (LRFD) method has been successfully applied to the design of hot-rolled steel sections and cold-formed steel members in the United States and foreign countries. In order to develop the LRFD criteria for the design of cold-formed stainless steel structural members and connections, a research project was conducted at the University of Missouri-Rolla since 1986 under the sponsorship of the American Society of Civil Engineers (ASCE). This newly developed LRFD Specification with Commentary has been adopted by ASCE as a new standard in 1990. It supersedes the 1974 edition of the Specification for the Design of …
