O primeiro processo de fracionamento, que foi aplicado ao fragmento 1, constituiu-se de cromatografia de exclusão (Bio-Gel A-50), seguida de cromatografia de troca iônica (DEAE - celulose) e resultou na eluição de quatro frações, denominadas respectivamente: FI/T; FII/T; FIII/T e FIV/T. Uma amostra de tecido mamário normal também foi submetida a este processo, tendo como resultantes as frações: FI/N e FII/N. O fragmento 2 foi submetido ao segundo processo de fracionamento, representado pelo emprego de cromatografia de afinidade (WGA - Sepharose 6 M8), que emitiu a obtenção da fração única, denominada F - NAG. Para efeito de analise comparativa, as diferentes frações protéicas foram submetidas: i) a analise eletroforetica em gel de poliacrilamida, na presença de SDS; 2) a analise imunoqu{mica, através de imunodifusio dupla e imunoeletroforese; 3) a analise do potencial de ligação lectina WGA_125I. A analise eletrofortica demonstrou a presença de vários componentes na fração FII/T, nio detectados nas fraç3es resultantes de tecido mam~rio normal, FI/N e FII/N. Alguns desses componentes encontraram correspondência na fração F-NAG, resultante da cromatografia de afinidade. Através da analise por imunodifusio foi possível detectar a presença de .componentes possivelmente associados ao tumor mamario, nas frações FI/T, FII/T, FIV/T e F-NAG. A analise imunoeletroforetica destas fraç3es permitiu esclarecer que o componente presente na fração F-NAG, com mobilidade 'alfa¿2 era distinto do componente aparentemente comum presente nas demais fraç3es, cuJa mobilidade era 'beta¿2. A analise do potencial de ligação WGA-125I revelou que somente a fração F-NAG continha componentes acessíveis ~ ligação com a lectina / Abstract: Not informed. / Mestrado / Mestre em Ciências Biológicas

In ultrasonic processing, it has been a practice to measure intensity of ultrasonics as a product of plate current and voltage as indicated on ultra sonic generator. At low frequencies the standard equipment is available, such as the sound level meter, to measure the absolute intensity, but at higher frequencies the problem becomes complicated by the diffraction effects on account of the size of the measuring device. In this investigation an attempt has been made to construct a measuring device (called the probe) to measure intensity. A small barium titanate cylindrical element (1/16 inch in diameter and 1/16 inch length) was used as a detector-convertor of sonic pressures. The alternating voltages thus produced were indicated by a vacuum tube voltmeter. This element was cemented in a hypodermic needle in turn was held in a lucite rod (1/2 inch in diameter and five inches in length) which served as a holder. This arrangement was used to probe the sonic fields of cylindrical and bowl shaped transducers. / Ph. D.

Early interest concerning the control of the green June beetle, Cotinis nitida Linn., also called the fig-eater, was recorded during the middle of the nineteenth century. Since that time farmers in Virginia and other Southeastern States have been trying to find better methods for the control of this insect. The larvae of this beetle, . en present in large numbers, are capable of almost completely destroying certain forage crops such as alfalfa and clover, not by direct feeding, but from the results of their search for food. The adult, although not of prime economic importance in this region, does cause considerable economic losses. It feeds on fruits from a number of different species of plants such as grapes, peaches, raspberries, apples, pears, plums and in particular figs, hence the common name fig-eater. A definite affinity also is shown towards certain grains such as corn and sorghum. / Master of Science

The solution of the equations of motion of an aircraft fuselage-landing gear configuration during landings is of interest to the designer who must predict the landing loads which an airplane encounters in service. In general such solutions are difficult because of the highly nonlinear characteristics of the oleo-pneumatic shock strut which couples the lower mass of the landing gear to the fuselage. In the past, attempts to obtain solutions by linearization of these shock strut characteristics have resulted in unrealistic predictions of landing gear motions. Therefore, it has been necessary to carry out most of the theoretical analysis associated with landing gears by means of numerical integration procedures. These numerical methods are tedious, and as a result a large portion of design work has been carried out by means of trial and error drop testing of a system of masses representative of an airplane and landing gear. This in turn has proved to be time consuming and expensive. This paper presents a method for obtaining an analytical solution of the equations of motion for a basically nonlinear system which closely resembles an actual airplane and landing gear configuration. The nonlinear system considered has two degrees of freedom and is composed of a large mass representative of the fuselage-wing combination connected by an oleo-pneumatic shock strut to a wheel. The shock strut is assumed to have velocity-squared hydraulic damping and coulomb friction forces on the strut bearings. The nonlinear spring characteristic of the tire is represented by a sectionally linear spring. In the first part of this paper the equations of motion for this nonlinear system are derived making use of a few simplifications which previous papers have shown to be justified. Also, the degree to which these assumptions limit the results is discussed. Next these equations of motion are solved in analytical form by a method which may be called "equivalent non linearisation." It is shown that this solution is exact only for a specific combination of impact parameters, but that for a wide range of parameters the solution describes the motion of the system adequately for design purposes. Finally, a few analytical solutions are compared with solutions obtained by numerical integration methods; and the results are compared with experimental data for a typical impact. / Master of Science

The purpose of this thesis project was to design and construct a free surface water table for the investigation of compressible-flow phenomena. Although the design range of operation of the water table was to include all desired analogous Mach numbers between 0.40 and 7.00, the range of operation was limited by the formation of unwanted waves at the entrance section. With the application of elastic glazing compound to provide a rounded entrance and with the addition of a wetting agent to reduce the surface tension of the water, the water table performed satisfactorily at analogous Mach numbers between 0.40 and 4.00. The test section depth could not be easily varied because it was necessary to fill the grooves of the gate guides, with elastic glazing compound, for each gate opening. Except for the entrance section, very satisfactory performance was attained with all the components of the water table. Satisfactory performance of the water table was verified by the flow photographs and the results of the representative tests. / Master of Science
