Properties of the Active Site of Enzymes

Description: In this paper some studies on enzyme properties which are believed to be pertinent to antibodies will be discussed. The particular studies chosen are; (a) the evidence that residues far removed from each other in the sequence play vital roles at the active site; (b) indications on the size of the active site; and (c) evidence for flexibility at the active site. Since the relation between enzyme and antibody is of primary interest an attempt will be made to emphasize the fundamental conclusions derived from the observations and to evaluate critically the deductions on structure and function which derive from these conclusions.

Cumulative Radiation Effects of Sexual Reproduction in Pine and Oak

Description: The sexual reproductive ability of a forest exposed to low level ionizing radiation is dependent on the sensitivity of primordial differentiation, meiotic processes leading to the formation of gametes, fusion of the gametes, and subsequent growth of the sporophytic generations. In this report it was shown that the initiation of reproductive primordia in Pinus rigida, Quercus ilicifolia, Quercus alba and Quercus coccinea is not unusually sensitive to irradiation. Trees which had been severely damaged by chronic low level ionizing radiation (4 to 12 r/20 hr day) were able to differentiate floral structures and produce viable seed. However, flower phenology was retarded, and pronounced morphological aberrations were present. It is suggested that this delay may be the result of a reduction of endogenous growth substances.

Progeny Test from a Pitch Pine-Oak Forest, Damaged by Low Level Chronic Gamma Radiation

Description: Ionizing radiation is useful to plant breeders in obtaining mutations beneficial from an economic point of view. This report, however, concerns our basic knowledge of radiation: attention is here directed to some effects of low level radiation on the R₁ progeny. Approximately one third of the land area of the United States is covered by forest; thus, forest trees form an important component of our natural wealth. It is therefore our obligation to know how these forests will react to low level ionizing radiation. Although this type of radiation might accompany atomic explosions, its effects may not be evident for a number of years.

Clonal Multiplication of Cymbidiums Through Tissue Culture of the Root Meristem

Description: The propagation of clonal varieties of some orchids is at times exasperatingly slow and occasionally an almost futile effort. Clonal multiplication is generally confined to dividing mature plants and to starting plants from pseudobulbs. There is, of course, the specialized technique for obtaining Phalaenopsis plantlets from the aseptic culture of inflorescence nodes, but this is basically the same thing as propagating plants from pseudobulbs. In certain cases it is highly desirable to rapidly multiply certain clones of orchids. Awarded varieties could thereby be dispersed with great rapidity where now it may take decades for some clones to became fairly common. Commercial flower production would be very much enhanced if certain desirable clones could be multiplied ad infinitum within a short time. Orchid flower production could then be placed more on a par with many of the other cut flowers and the clonal peculiarities of some of the current hybrids could be pampered instead of ignored. This paper describes a tissue culture method for the rapid propagation of Cymbidium clones

"Ages" of the Sikhote Alin Meteorite

Description: The potassium-argon age of the Sikhote Alin iron meteorite has been determined. The value is 1.7 + 0.2 x 10⁹ years. Previous lead data suggest an age of 4.6 x 10⁹ years . The date of solidification may be the sum of these two ages.

Servo Stabilized RF Vernier Time-of-Flight Analyzer

Description: The analyzer can be operated either internally or externally. The 10 ma germanium discriminator is quiescently biased to 8.5 ma in its low-voltage state. An input signal current of 3.5 ma or more triggers it to its high voltage state. This triggers the oscillator. The oscillator signal is buffered and mixed in the bridge modulator with the reference radiofrequency signal from the cyclotron. The low-frequency beat note from the bridge modulator is squared up and passed to the beat zero univibrator which generates 0.7 mu sec signals each time the beat note passes through zero from positive to negative. The trailing edge of the beat zero univibrator is employed to terminate the time-of-flight measurement and to control the servo measurement. Drawings are included. (M.C.G.)

Beam Current Integrator

Description: The object of this report is to acquaint the operator with the operational and technical aspects of the beam current integrator as well as the theory of the system operation. The design and operation of a beam current integrator are described, and the theory of operation is discussed. The instrument has two channels. The console channel is designed to measure the accumulation of charge received by a target during a period of a day no matter what the range used in the experimenter's channel. An analysis indicated that this unit will measure the accumulation of charge by a target to an accuracy of 0.1215% assuming that the constant error due to shorting the integrating capacitor is accounted for. The instrument is ranged to handle from 0.5 to 500 mu a of beam current. (M.C.G.)

Digital-to-Analogue Converter (Punched Tape to X-Y Plotter)

Description: A digital-to-analog converter is described which is a part of a system that converts punched-tape digital data to analog data in a series of points drawn by an x-y plotter. The converter is designed to plot accurately tapes that contain information other than coded numerical coordinates. Operation of the converter is also described along with format requirements and power supplies. (J.R.D.)

Possible Use of a Betatron Core on the Cosmotron

Description: Most existing electron synchrotrons use betatron start for initial acceleration of the particles. The subsequent synchrotron acceleration is then performed with a nearly constant radio-frequency. Investigation of the effect of turn-on rate and initial energy spread is made mathematically. Several advantages are seen for such a technique. (D.C.W.)

Efficiency pf Multiple Traversal Targets

Description: The efficiency of multiple traversal targets is defined as the probability that a proton dies by making a nuclear collision in the target rather than by hitting the limit of the synchrotron aperture. The efficiencies of Be, Al, Cu, and Pb targets are shown for 15 and 30-Bev protons in the Brooknaven AGS. Beryllium was found to be the most efficient. (M.C.G.)

Acceleration of Polarized Protons to Relativistic Energies

Description: Maintenance of polarization of polarized protons in a linear accelerator is known to be feasible. Circular accelerators present a different problem, and the investigation of the interaction of orbit dynamics and particle polarization in general is undertaken. The equation of motion of the spin vector of a charged particle in a magnetic field as formulated by Bargmann, Michel, and Telegdi is utilized in the study of depolarization for several accelerators. High values of depolarization are obtained, and means for avoiding such depolarization are suggested. (D.C.W.)

Time Dependence of Space Charge Beam Losses in the Cosmotron

Description: An investigation was made of Cosmotron intensity versus time through the entire time interval from the beginning of injection to the completion of r-f capture. The induction electrode signal was used for the instantaneous measurement of beam intensity. Oscilloscope displays of the signal were photographed and traced. Base lines were filled in on the tracings and the area of the pulses measured with a polar planimeter. It was found that the relation losses of beam intensity increase with injection intensity (total injected charge), and that most of the losses take place in the time interval between the end of injection and the completion of the first synchrotron oscillation
