A Study Of The Adsorption Of Some Atmospheric Gases On Soils Of The Willamette Valley River Basin, Thomas R. Quale Dec 1973

A Study Of The Adsorption Of Some Atmospheric Gases On Soils Of The Willamette Valley River Basin, Thomas R. Quale

Dissertations and Theses

Recent work indicates that microorganisms present in soils can remove carbon monoxide from the atmosphere and as such constitutes a major sink. B.E.T. adsorption studies were carried out on representative soils from the Willamette Valley River Basin in order to determine their adsorptive characteristics for carbon monoxide and other gases. Attempts were made to isolate, through a non-soildestructive sterilization, the adsorptive characteristics of the soil microorganisms as well as of the test soil.

The carbon monoxide studies show physical adsorption equivalent to the coverage of a few per cent of the surface area at 25.0° and 76 cm-Hg. Adsorption studies …

The Mediterranean Coast Of Israel: A Planner's Approach, Sophia Professorsky Dec 1973

The Mediterranean Coast Of Israel: A Planner's Approach, Sophia Professorsky

Marine Affairs Theses and Major Papers

The coastal zone of Israel is facing an ever-growing pressure of varied and conflicting land uses. Spreading urbanization, from Nahariya in the north to Ashkelon in the south, gnaws agricultural areas; the needs for commercial ports and industrial plants stand in conflict with recreational uses of the seashore and, as described before, the natural conditions of land shelf structure, topography and climate, are favourable for both industry and residence so that the narrow stretch of the coastal zone attracts more and more of them.

A Study Of Vector And Matrix Norms, Alvena Weiskircher Dec 1973

A Study Of Vector And Matrix Norms, Alvena Weiskircher

Theses & Honors Papers

A vector or matrix can be associated with a single nonnegative scalar . Basically this is the concept of a vector or matrix norm. While the study of these norms may be classified as numerical analysis , a limited background in linear algebra , matrix theory , and advanced calculus is sufficient to pursue the study of norms.

In this paper many of the properties and theorems concerning norms have been proven . It is thought that the most important results deal with the use of vector and matrix norms in testing for convergence of sequences and series of matrices …


Truncated Circular Normal Distribution With Applications In Ballistics And Meteorology, Danny D. Dyer Dec 1973

Truncated Circular Normal Distribution With Applications In Ballistics And Meteorology, Danny D. Dyer

Mathematics Technical Papers

The use of the circular normal distribution (CND) to describe the behavior of random phenomena of a geophysical nature has been discussed by Crutcher [7, p. 9]. Based on the Mauchly [17] - Hsu [12] test, the harmonic dial points (the Fourier coefficients obtained from harmonic analysis of observations of periodic phenomena) representing i.) lunar semidiurnal atmospheric tides (Chapman and Lindzen [5, p. 66]), ii.) the westerly component of wind in the study of tidal oscillations in the upper atmosphere (Haurwitz [10]), and iii.) terrestrial-magnetic activity relative to solar activity (Bartels [2]) may be treated as observations from a CND. …

Existence Md Estimates For Solutions Of Nonlinear Equations Near A Branch Point, Jerome Eisenfeld, V. Lakshmikantham

Mathematics Technical Papers

Consider the equation (1.1) [see pdf for notation] on a Hilbert space H. Here n is a scalar and [see pdf for notation] is a linear Fredholm operator. That is: (a) L is closed; (b) The domain, D(L) is dense in H; (c) The range, R(L) is closed in H; (d) The dimension of the null space, dim n(L) <= (e) The dimension of the null space of the adjoint dim n(L*) <= The operator N, which may be nonlinear, is defined for sufficiently small and appropriately restricted [see pdf for notation], and [see pdf for notation] Using the method of Lyapunov-Schmidt (cf., e.g. [4] or [5]) we express w in the form (1.2) [see pdf for notation] where [see pdf for notation] denotes the orthogonal complement of n(L) in H. Suppose (u,v) satisfy the simultaneous equations (1.3) [see pdf for notation] (1.4) [see pdf for notation] where P is the orthogonal projection operator of H onto R(L), I is the identity operator on H, and J is a right inverse of L on R(L), i.e.

A Direct Measurement Of The Ratio Of The Reaction Cross Sections For Two-Photon And Three-Photon Positron Annihilation In Aluminum And Silver, Robert Maurice Heavenrich Dec 1973

A Direct Measurement Of The Ratio Of The Reaction Cross Sections For Two-Photon And Three-Photon Positron Annihilation In Aluminum And Silver, Robert Maurice Heavenrich

Masters Theses

The probability of annihilation of a positron with its antiparticle, an electron, is spin dependent. Since both particles have spin component one -half, there are two possible relative orientations of their spins they can either be aligned (parallel) in the 3S, triplet, state with total spin component │Sz│= ½ n - ½ n = 1 n or they can be opposite (antiparallel) in the 1S; singlet, state with│Sz│= ½ n - ½ n = 0. To conserve energy and angular momentum, annihilation from the triplet state must result in the creation of an odd …
