Energy Conservation In The Manufacturing Process, Paul H. Kaiser Apr 1974

Energy Conservation In The Manufacturing Process, Paul H. Kaiser

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

My presentation will cover the basic procedure used by the Emerson Electric Co. to conserve energy in Its operations. And because people frequently tell me how much they like or dislike our television sets, and how concerned they are or are not about the depth of our involvement in furnishing material for the Defense Department, at this point I would like to give a short commercial. Hopefully, it will dispel misconceptions, and define the use of energy in Emerson's operations.

The Role Of Natural Gas And Lng In Supplying Our Energy Needs, D. L. Caldwell Apr 1974

The Role Of Natural Gas And Lng In Supplying Our Energy Needs, D. L. Caldwell

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The domestic natural gas industry experienced a spectacular growth during the two decades from 1950 to 1970. Demand for gas continues to rise and production has peaked at a time when the price for other energy sources is escalating. A price increase can stimulate production over the short term. Massive LNG imports can help the intermediate term supply. The long term natural gas situation is bleak and substitute natural gas sources must be employed. A conservation program and reordering of priorities for energy sources is essential for the United States as well as most industrial nations.


Oil Spill Containment And Removal In Arctic Ecosystems, Wilfred R. Mcleod, Diana L. Mcleod Apr 1974

Oil Spill Containment And Removal In Arctic Ecosystems, Wilfred R. Mcleod, Diana L. Mcleod

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Statistics on 16 arctic and subarctic oil spills, their locations, the amount of oil spilled, combatant schemes used, and causes for the spills were culled from the literature. This information has been used to analyze the effectiveness of available chemical, mechanical, and destructive means of oil recovery or disposal under arctic and subarctic conditions.

The choice of the best cleanup procedures to follow in any particular instance is clouded by a number of variables and must be weighed against such considerations as wind, sea, and ice conditions, properties of the oil, and effects of chemicals on marine and wildlife. Access …


A Technique For Improving Stability Of Petroleum Reservoir Simulation Models, M. D. Arnold, T. C. Wilson, A. Herbert Harvey Apr 1974

A Technique For Improving Stability Of Petroleum Reservoir Simulation Models, M. D. Arnold, T. C. Wilson, A. Herbert Harvey

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Computational instability may occur in the mathematical simulation of hydrocarbon reservoirs when small inaccuracies in the calculated pressures cause loss of diagonal dominance in the matrix of coefficients. The problem can be resolved by the use of a more precise technique for computation of pressures. However, this stability problem is still troublesome to users of certain types of reservoir simulators. A computational technique which has been found effective in resolving the problem is presented.

The Assessment Of Environmental Impacts At Nuclear Power Generating Stations, Thomas H. Row, J. R. Mcwherter Apr 1974

The Assessment Of Environmental Impacts At Nuclear Power Generating Stations, Thomas H. Row, J. R. Mcwherter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The Federal actions that are required with regard to nuclear power stations are the granting of a construction permit and later the issuance of a license to operate the station. Since the Atomic Energy Commission (AEC) is responsible for these actions, the Commission is also responsible for preparation of an environmental statement on the proposed actions. The National Laboratories including the one at Oak Ridge are used as part of the staff in preparing the statements.

The staff makes an independent determination of the plant effluents and their dispersions. The impact of these and plant construction on the environment are …

Energy Conservation: Constructive But No Cure, N. V. Poer Apr 1974

Energy Conservation: Constructive But No Cure, N. V. Poer

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Let me share with you a quotation from a report issued bv the Chase Manhattan Bank while the Arab oil embargo was still in effect. "Reportedly, the annual cost of a gasoline rationing program would amount to $1.4 billion. Based upon past results, if that much money was devoted to an exploratory effort, it would be potentially capable of discovering more than 2 billion barrels of petroleum. That amount of petroleum would be equal to 19 percent more than all the gasoline consumed in privately owned automobiles in 1973."

While the threat of rationing has disappeared with an end to …


International Regulation Of Marine Pollution From Land-Based Sources, Richard Tucker Scully Apr 1974

International Regulation Of Marine Pollution From Land-Based Sources, Richard Tucker Scully

Marine Affairs Theses and Major Papers

Most of the waste products of human society end up in the oceans and the number and quantities of pollutants entering the oceans have been increasing at exponential rates. Recognition of these trends has resulted in expansion of international environmental attention to include sources of marine pollution other than vessels. Source, in this sense, refers to the pathway through which pollutants reach the sea. Land-based sources accounts for the vast bulk of the pollutants reaching the oceans. Effective protection of the marine environment, therefore, must include regulation of land-based sources of marine pollution.

Maximal And Minimal Solutions And Comparison Results For Differential Equations In Abstract Cones, V. Lakshmikantham, Roger W. Mitchell, A. Richard Mitchell Apr 1974

Maximal And Minimal Solutions And Comparison Results For Differential Equations In Abstract Cones, V. Lakshmikantham, Roger W. Mitchell, A. Richard Mitchell

Mathematics Technical Papers - Archive

As is well known, an important technique in the theory of differential equations is concerned with estimating a function satisfying a differential inequality by means of the extremal solutions of the corresponding differential equation. This comparison principle has been widely employed in studying the qualitative theory of differential equations (see [3]). If we desire to develop a similar comparison result in abstract spaces we must consider cones. These results could be of great value in applications to the theory of differential equations in abstract spaces. First, we must consider existence results for maximal and minimal solutions in cones which can …


Lyapunov-Like Vector Functions Using Pointwise Degenerate Systems As Comparison Functions, Bernard A. Asner, V. Lakshmikantham Apr 1974

Lyapunov-Like Vector Functions Using Pointwise Degenerate Systems As Comparison Functions, Bernard A. Asner, V. Lakshmikantham

Mathematics Technical Papers - Archive

The use of Lyapunov-like vector functions is recognized as an important tool for estimating the behavior of a dynamical system. In applications, one needs to determine a suitable comparison function which contains information or properties that can be used to obtain some information about the behavior of the dynamical system. In recent years, the remarkable property of pointwise degeneracy has been discovered for linear, autonomous, delay-differential equations. For this class of equations one knows that all solutions will reach a subspace in finite time and remain on the subspace thereafter. As this class of equations is particularly simple, it becomes …


Macrocyclic Polyether Sulfide Syntheses, The Preparation Of Thia-Crown-3, 4, 6, And 7 Compounds, Yau-Kwong Joseph Hui Apr 1974

Macrocyclic Polyether Sulfide Syntheses, The Preparation Of Thia-Crown-3, 4, 6, And 7 Compounds, Yau-Kwong Joseph Hui

Theses and Dissertations

Macrocyclic polyether sulfides have been prepared by reacting an oligoethylene glycol dichloride with a dithiol or sodium sulfide in ethanol. The following new compounds were prepared: 1-thia-(9-crown-3), 1,4-dithia-(9-crown-3), 1,4-dithia-(12-crown-4), 1,4,7-trithia-(12-crown-4), 1-thia-(18-crown-6), I,4-dithia-(18-crown-6), 1,7-dithia-(18-crown-6), 1,4,7-trithia-(18-crown-6), 1,7-dithia-(21-crown-7), 1,4,7-trithia-(21-crown-7). Four other previously reported macrocyclic polyether sulfides were also prepared. The symmetry of the nmr spectra of these compounds give added evidence for the proposed ring structures. The following subjects were presented and discussed: studies of cyclization by-products, dependence of cyclization yield on the size of the rings, high dilution principle and its application, medium-sized rings, effect of hetero-atoms on cyclization and melting point …


The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen Apr 1974

The Solution Photochemistry Of Benzaldehyde In Benzene, Ethanol, And 1-Hexyne, Ronald Douglas Knudsen

Theses and Dissertations

The photoreactions of benzaldehyde in benzene, ethanol, and 1-hexyne have been studied. Irradiation of benzaldehyde in benzene produces benzoin (I), hydrobenzoin (II), and deoxybenzoin (III). Irradiation of benzoin (I) in this solvent results in benzaldehyde formation as well as small amounts of (II) and (III). The ethanol irradiation of benzaldehyde resulted, predominantly, in the formation of (II) with (I) formed in small amounts. The photolysis of benzaldehyde in 1-hexyne produces (I), (II), (III) cis-2-heptenophenone (VII), trans-2-heptenophenone (VIII), heptanophenone (IX), and 2-(n-butyl)- 1,4-diphenyl-1,4-butanedione (X). Mechanistic pathways for the formation of these photoproducts are discussed. Separation and characterization of cis- and trans-2- …


A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch Apr 1974

A Calorimetric Study Of Metal Binding In Carboxypeptidase, Carbonic Anhydrase And Concanavalin A, Gary E. Hatch

Theses and Dissertations

The purpose of this study was to perfect a new calorimetric method for identifying and counting ionizable chemical groups on proteins. To do this, calorimetric and electrometric titrations were performed (using HCl and NaOH as titrant) on native carboxypeptidase, carbonic anhydrase and concanavalin A plus their apo and organic ligand bound derivatives. Readily identifiable endpoints were seen in the calorimetric titrations and general agreement was found between ΔH values obtained in this study and literature ΔH values of model compounds undergoing the same reaction. Imidazole groups were those most easily counted. Many assumptions had to be made, however, in concluding …

The Port Of Boston: Perspective On A Maritime Dilemma, Louis Edward Cellineri Apr 1974

The Port Of Boston: Perspective On A Maritime Dilemma, Louis Edward Cellineri

Marine Affairs Theses and Major Papers

Few in Massachusetts, or even in the metropolitan Boston area, however, understand their Port's past, and few still appreciate its present contributions and sympathize with its struggles and problematic future. Whatever its past fame or present indignities, the excitement of a vibrant, profitable waterfront does not enter into the advocacy and implementation of harbor recreational and residential development plans, with or without commercial activities. This near dismissal of the Seaport's present and potential value in certain circles, only presents another dilemma to those attempting to cope with this veritable maritime bag of worms. But despite all these obstacles, the Port …

Use Of Chlorophacinone In The Struggle Against The Common Vole (Microtus Arvalis Pallas) And Against The Muskrat Ondatra Zibethica L.), J. Giban Mar 1974

Use Of Chlorophacinone In The Struggle Against The Common Vole (Microtus Arvalis Pallas) And Against The Muskrat Ondatra Zibethica L.), J. Giban

Vertebrate Pest Conference Proceedings: 6th (1974)

The use of the anticoagulant rodenticide, chlorophacinone, was largely developed in France during the last ten years. Its special properties, with respect to those of other anticoagulants currently known, have contributed largely to finding an effective and economically acceptable solution in the struggle against the two most damaging rodents in France: the common vole (Microtus arvalis P. ) and the muskrat (Ondatra zibethica L. ).


Recent Changes In Federal Bird Control, Gene H. Wilson Mar 1974

Recent Changes In Federal Bird Control, Gene H. Wilson

Vertebrate Pest Conference Proceedings: 6th (1974)

Probably the most significant changes in U. S. Fish and Wildlife Service legislation that might have an effect on those engaged in animal control work would have to do with the Migratory Bird Treaty Act, the Fish and Wildlife Act of 1956 recently amended, and one piece of proposed legislation which I'll mention at closing.

In March 1972, an amendment to our treaty with Mexico became effective. And more recent, the Fish and Wildlife Act of 1956 had a section added to it having to do with airborne hunting.

About two years ago, the amendment to the Mexican treaty added …


The Role Of F.A.O. In Vertebrate Pest Problems, H.R. Shuyler Mar 1974

The Role Of F.A.O. In Vertebrate Pest Problems, H.R. Shuyler

Vertebrate Pest Conference Proceedings: 6th (1974)

Since 1947, when FAO began its involvement in vertebrate pest problems, its role has gradually expanded. Through short-term Consultants, Experts, Regional and Headquarters Officers, it advises Member Countries about vertebrate pest control needs and opportunities, fulfills requests for assistance suggesting needed modifications, and guides and reports on assistance rendered. Assistance may involve one or more international specialists for a few weeks up to national and regional projects of several years' duration. In cooperation with WHO it sponsors meetings of specialists, develops rodenticide specifications for international commerce, and has published rodent bibliographies covering 1950 to 1969.

This decomposition provides information about the weight distribution of the code.


On The Existence Of Solutions Of Differential Equations In A Banach Space, Jerome Eisenfeld, V. Lakshmikantham Mar 1974

On The Existence Of Solutions Of Differential Equations In A Banach Space, Jerome Eisenfeld, V. Lakshmikantham

Mathematics Technical Papers - Archive

The study of Cauchy problem for differential equations in a Banach space has taken two different directions. One approach is to find compactness type conditions [1,2,4,9,14] to guarantee existence of solutions only and the corresponding results are extensions of the classical Peano's Theorem. The other approach is to employ accretive type conditions [9,10,11,12,15] which assure existence as well as uniqueness of solutions. In fact, this latter technic shows that uniqueness conditions imply existence of solutions [16]. In this paper we follow the first direction. Employing Lyapunov-like functions and the notion of the measure of noncompactness, we prove a local existence …

A differential system [see pdf for notation] where [see pdf for notation] has asymptotic equilibrium if 1) for any initial condition [see pdf for notation] the system has a solution [see pdf for notation] existing on and such that [see pdf for notation] exists and is finite, and 2) for any v e B there exists [see pdf for notation] and a solution x(t) of (1)-(2) with [see pdf for notation] Several papers have appeared dealing with asymptotic equilibrium of (1)-(2) when [see pdf for notation], and f is majorized by a scalar function g(t,u) which is monotone in u …


Fixed Point Theorems Through Abstract Cones, Jerome Eisenfeld, V. Lakshmikantham Mar 1974

Fixed Point Theorems Through Abstract Cones, Jerome Eisenfeld, V. Lakshmikantham

Mathematics Technical Papers - Archive

A well-known theorem of Banach states that if T is a mapping on a complete metric space [see pdf for notation] such that for some number [see pdf for notation], the inequality (1.1) [see pdf for notation] holds, then T has a unique fixed point (i.e., a point u such that Tu = u). Extensions of this theorem [1,2] continue to require that T is a contraction i.e., (1.2) [see pdf for notation] This condition is essential if p is a metric but if p takes values in a partially ordered set k, then the condition (1.2) is avoidable. In …

On Perturbing Lyapunov Functions, S. Leela, V. Lakshmikantham Feb 1974

On Perturbing Lyapunov Functions, S. Leela, V. Lakshmikantham

Mathematics Technical Papers - Archive

It is known [2,3] that in proving uniform boundedness of a differential system by means of Lyapunov functions, it is sufficient to impose conditions in the complement of a compact set in [see pdf for notation], whereas, in the case of equiboundedness, the proofs demand that the assumptions hold everywhere in [see pdf for notation]. We wish to present, in this paper, a new idea which permits us to discuss nonuniform properties of solutions of differential equations under weaker assumptions. Our results will show that the equiboundedness can be proved without assuming conditions everywhere in [see pdf for notation] (as …
