This paper discusses several approaches that can be used by chemists to design safer chemical substances. Theses approaches include: reducing absorption; understanding toxic mechanisms; using structure-activity relationships, retrometabolism, and isosterism; eliminating the need for associated toxic substances; and identifying equally useful, less toxic substitutes of another chemical class. Specific examples of the successful commercial application of these approaches are presented.
This paper provides chemists with a strategic framework for the rational design of safer chemicals from the standpoint of pollution prevention and green chemistry.

Project 9. Project Definition of limiting damage levels. No detailed description in provided criteria for component strain limits. However, this is not standard terminology. While there are a few variations on the basic practices, the criteria identify the following basic elements of current engineering practice for non-conventional bridges: 1. All project criteria provide for a limited ductility design basis.
All projects in moderate and high seismic zones provide for repairable damage at the safety- level seismic event. Most criteria call for design for both a functional and a safety-level event. Most criteria establish allowable strain levels to establish acceptance for each limit state. All project criteria for bridges in moderate and high seismic zones require design based on a nonlinear time-history analysis.
Most U. One criteria document was obtained for a moderate seismic region see Project One cri- teria document was also obtained for a low seismic region see Project 6 , which illustrates how the AASHTO BDS is applied for seismic design where seismic does not control lateral forces. The use of elastic seismic forces in a force-based design is used without applying capacity design provisions; however, pushover analysis was performed to determine the limiting lateral force mechanism for the structural system.
For these elastic seismic design cases, lateral force demands such as vessel impact and wind are similar to or greater than the level of elastic seismic forces based on the AASHTO BDS criteria. A full ductility design is not applied in these cases, since it would result in significant increase in foundation and other related costs without any com- mensurate benefit in life safety. The project-specific criteria address the basis for limited ductility design, which is a local and global bending design basis.
Detailing for confinement, shear design, and minimum reinforcing requirements all are drawn from the AASHTO BDS and Guide Spec, and as such follow the design basis for shear and confinement as applied to conventional bridges. This point is described in more detail as it relates to the approach to capacity protection for non-conventional bridges.
Table 6 summarizes the project-specific criteria for non-conventional bridges drawn from the criteria documents in this section. There are variations within the current engineering practice as to how some of these criteria are implemented. The major items are described in the following sections. Other criteria documents obtained from high seismic zone locations have simi- lar performance measures.
The criteria reference the limit-state capacity protection concept through differential strain limitations for capacity protected elements based on a demand dis- placement check rather than a singular plastic column criterion the bridge in Table 7 included a shear-linked tower This approach to capacity protection is employed to assess strain- based damage levels associated with limited ductility design. In the high seismic regions of California, the dominance of ground motion for lateral forces and foundation design gener- ally removes the issue of competing demands that can occur in regions of lower seismicity.
In regions with moderate and lower seismic demand, competing lateral force demands can factor. State of Practice Based on Project Criteria 17 into the performance measures, and may control design requirements. However, application of a demand displacement-based capacity check eliminates the conflict that otherwise can occur with the single limit-state criterion. Means by Which Nonlinearity Is Considered The details of nonlinear analysis vary with the specific project criteria, the characteristics of the structure type, and the differing standards of practice among engineers.
The procedures for nonlinear analysis vary according to the degree of detail needed to address the performance requirements established for a project. In those cases where performance requirements are descriptive damage states, the nonlinear material model is sometimes limited to iterative defi- nitions of effective stiffness or local moment-curvature definitions at assigned inelastic zones within the structural model.
In those projects with defined allowable strain limits for perfor- mance limit states, material models will be based on full moment-curvature-axial interaction definitions for nonlinear section response, either over the full extent of major members or at assigned hinge locations. In both cases, the nonlinear analyses incorporate geometric nonlinear- ity, which for some non-conventional bridges influence review for drift criteria of towers and long-span arches.
For non-conventional bridges on deep foundations, particularly those in riparian and marine environments, foundation modeling for nonlinear analysis represents a significant effort and source of variability in the design process. In several of the bridges in the criteria review, a full dis- cretized foundation model of piles was included for soil structure interaction. Sufficient models exist for liquefied and non-liquefied soil conditions. However, the triggering mechanisms to Item Typical Project-Specific Criteria Seismicity Characterization In regions of high seismicity, the typical project-specific ground motions are based on a probabilistic site hazard analysis, with a suite of motions to address multiple sources for each level of ground motion functional and safety events Typical Design Standard Design is based on damage limit states that apply to both ductile and protected elements within the structure, based on either a general description of the target damage levels moderate, repairable, or significant or on quantitative strain limits that are assigned to these same damage limit states.

Nonlinear, inelastic dynamic analysis is used to determine compliance with strain-based performance standards. Member Protection Protocol The separation of ductile element design from protected element design is achieved through a separation of allowable strains at each damage limit state so that at the given performance limit state, the ductility level associated with the damage state is limited to the members and elements selected for ductile behavior, and the protected elements experience low or essentially elastic strain demands.
Ground Motion Definition Spectrally matched ground motion time histories are typically developed for both functional- and safety- level events. Site Class Definition geotechnical characterization Project-specific site characterization does not follow conventional bridge standards, since the specific soil characteristics are modeled for the soil-structure interaction analysis.
Analysis Type Nonlinear time history for force and displacement. Deep Foundation Modeling Discrete foundation modeling with nonlinear soil springs [or as determined from finite element analysis FEA models ], ground motion input with depth, and radiational damping. Table 6. Summary of criteria for non-conventional bridge seismic design. The general practice today is to bracket the liquefied and non-liquefied conditions when assessing compliance with performance criteria.
The discretization and data management needed for tracking strain time history in a non linear regime is considerably more involved than for the more general structural analysis. The distribu- tion of inelastic response is a product of the analysis, and the concurrent forces associated with member response are tracked in the time domain and post-processed back through the associated moment-curvature section definitions to report element strains.

Section 2: That Table in Section Section 3: That Section When permitted by special use permit in the RR, R1, R2, and R3 Districts, or as a permitted use in other zoning jurisdictions as set forth in Table of Section Article Four presents the Zoning District Regulations.
Zoning Districts are established in the Zoning Ordinance to promote compatible land use patterns and to establish site development regulations appropriate to the purposes and specific nature of each district. The following base districts and overlay districts are hereby established. Table displays the purposes of these districts. A base district designation shall apply to each lot or site within the city and its planning jurisdiction.
A site must be in one base district. Overlay districts may be applied to any lot or site or any portion thereof, in addition to a base district designation. The Mixed Use District may stand alone as a base district. References in the Zoning Ordinance to less intensive or more intensive districts shall be deemed to refer to those agricultural, residential, commercial, and industrial base zoning districts established in Section The Overlay Districts shall not be included in this reference. Supplemental Regulations may affect specific land uses or development regulations in each zoning district.
The applicable Supplemental Regulations are noted in Table Notes to Preceding Pages: Tables and Rural Residential development situated within one of the designated rural development areas of the Comprehensive Plan may occur on minimum lot sizes below 1. Six feet for single-story construction, one foot for each 4 feet for any building over 24 feet in height.
See Section The 3, square feet per townhouse unit applies for up to 10 units in townhouse developments in the R-2 district. All allowable accessory buildings to a residence shall be limited to a maximum of one thousand two hundred feet 1, and for a maximum of three 3 detached structures for the first one acre or less.

Accessory structures larger than two hundred and fifty square feet shall be constructed with similar materials of the primary residence or building in residential and commercial zoning districts. Residential Use in multi-story structures in the DC zoning district, as well as family and group cares, emergency residential, group care, group home, religious assembly, and bed and breakfast uses will be located in the floor or floors above commercial uses.
Special Districts provide for base districts that allow multiple land uses and flexible development, with the requirement that a specific plan for the area be submitted by applicants. Overlay Districts are used in combination with base districts to modify or expand base district regulations. Overlay Districts are adapted to special needs of different parts of the City of Dickinson. To provide flexibility in development and to encourage innovative design through comprehensively planned projects.
The PUD Planned Unit Development Overlay District is intended to provide flexibility in the design of planned projects; to permit innovation in project design that incorporates open space and other amenities; and to insure compatibility of developments with the surrounding urban environment. The PUD District, which is adopted by the City Commission with the recommendation of the Planning Commission, assures specific development standards for each designated project.
Any use listed in this Code as a permitted or special use may be allowed. Any other use that the Commission finds compatible with the existing and planned uses in the development and on adjacent properties may be allowed. However, each approved use must be listed in the PUD and included in the approval ordinance adopted by the Commission.
A PUD may be established exclusively for residential, commercial or industrial development or any combination of those types of development. A property owner shall have the option of choosing to conform with the underlying zoning district regulations or the established PUD approval, if the PUD was adopted by the Commission prior to the adoption of this chapter.
Each PUD District must abut a public street for at least 50 feet and gain access from that street. A tract map, showing site boundaries, street lines, lot lines, easements, and proposed dedications or vacations. A land use plan designating specific uses for the site and establishing site development regulations, including setback height, building coverage, impervious coverage, density, and floor area ratio requirements.

The Planning Commission, after proper notice, shall hold a public hearing and act upon each application.
The recommendation of the Planning Commission shall be transmitted to the City Commission for final action. Proper notice shall mean the same notice established for any other zoning amendment. All approved plans shall be filed with the Zoning Administrator. Major amendments to the Development Plan must be approved according to the same procedure set forth in Section The City shall not issue a building permit, certificate of occupancy, or other permit for a building, structure, or use within a PUD District unless it is in compliance with the approved Development Plan or any approved amendments.
If no substantial development has taken place in a Planned Unit Development District for one year following approval of the District, the Planning and Zoning Commission shall reconsider the zoning of the property and may, on its own motion, initiate an application for rezoning the property. This district is intended to permit limited agricultural activities in combination with residential land uses. It recognizes the rural character of areas adjacent to Dickinson which may combine residential development at moderate densities with certain farm uses, including the raising of crops and animals, and the storage of agricultural products.
It further recognizes that such uses should be strictly controlled in order to minimize effects on neighboring properties. In addition to those uses permitted in the base district, the following additional uses are permitted in the Agricultural Business Overlay District:.

Any protest against an A Overlay District shall be made and filed as provided by the Century Code of North Dakota, and amendments thereto. It is the purpose of this ordinance to promote the public health, safety and general welfare and to minimize those losses described in Section Restrict or prohibit uses which are dangerous to health, safety, or property in times of flooding or cause undue increases in flood heights or velocities.
Require that uses vulnerable to floods, including public facilities which serve such uses, be provided with flood protection at the time of initial construction. Protect individuals from buying lands which are unsuitable for intended purposes because of flood hazard. Assure that eligibility is maintained for property owners in the community to purchase flood insurance in the National Flood Insurance Program when identified by the Federal Insurance Administration as a flood prone community.
Flood hazard areas of the City of Dickinson, North Dakota, are subject to inundation which results in loss of life or property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. These flood losses are caused by a the cumulative effect of obstruction in floodways causing increases in flood heights and velocities, b the occupancy of flood areas by uses vulnerable to floods or hazardous to other which are inadequately elevated or otherwise protected from flood damages.
Methods Used to Analyze Flood Hazards. This ordinance uses a reasonable method of analyzing flood hazards which consists of a series of interrelated steps. In all areas covered by this ordinance, no development shall be permitted except upon a permit to develop granted by the City Council or its duly designated representative under such safeguards and restrictions as the City Council may reasonably impose for the promotion and maintenance of the general welfare, health of the inhabitants of the community as contained in the City Code.
The boundaries of the floodway and floodway fringe overlay districts shall be determined by scaling distances on the official zoning map. Where interpretation is needed to the exact location of the boundaries of the districts as shown on the official zoning map, as for example where there appears to be a conflict between a mapped boundary and actual field conditions, the Enforcement Officer shall make the necessary interpretation.
In such cases where the interpretation is contested, the Board of Adjustment will resolve the dispute. The base flood elevation for the point in question shall be the governing factor in locating the district boundary on the land. The person contesting the location of the district boundary shall be given a reasonable opportunity to present his case to the Board and to submit his own technical evidence if he so desires. No development located within known flood hazard areas of the community shall be located, extended, converted or structurally altered without full compliance with the terms of this ordinance and other applicable regulations.
It is not intended by this ordinance to repeal, abrogate or impair any existing easements, covenants or deed restriction. However, where this ordinance imposes greater restrictions, the provision of this ordinance shall prevail. All other ordinances inconsistent with this ordinance are hereby repealed to the extent of the inconsistency only.
In their interpretation and application, the provisions of this ordinance shall be held to be minimum requirements and shall be liberally construed in favor of the City of Dickinson and shall not be deemed a limitation or repeal of any other powers granted by state statute. The degree of flood protection required by this ordinance is considered reasonable for regulatory purposes and is based on engineering and scientific methods of study.
Larger floods may occur on rare occasions or the flood height may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This ordinance does not imply that areas outside floodway and floodway fringe district boundaries or land uses permitted within such districts will be free from flooding or flood damages.
This ordinance shall not create liability on the part of the City of Dickinson or any officer or employee thereof for any flood damages that may result from reliance on this ordinance or any administrative decision lawfully made thereunder. If any section, clause, provision or portion of this ordinance is adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this ordinance shall not be affected thereby. Where a request for a permit to develop is denied by the Zoning Administrator, the applicant may apply for such permit or variance directly to the Board of Adjustment.
Procedures for appeals to the Board of Adjustment shall proceed as set forth by Section No person, firm, or corporation shall initiate any development or substantial improvement or cause the same to be done without first obtaining a separate permit for development as defined in Section C. The Zoning Administrator is hereby appointed to administer and implement the provisions of this ordinance.http://api.prod.leadereq.ai/how-to-put-tracking-on-a-smartphone-galaxy-a60.php
