MUTATIONS OF BACTERIA FROM VIRUS SENSITIVITY TO VIRUS RESISTANCE

This article reported Luria and Delbruck's breakthrough study in which they established that viruses do not induce mutations in bacteria, but that virus-resisting mutations are spontaneous. Their "fluctuation test" theory demonstrated that bacteria...

Statistical Mechanics of Cross‐Linked Polymer Networks II. Swelling

The interaction of solvents with cross‐linked network structures, such as occur in vulcanized rubber, is subjected to a statistical mechanical treatment based on the model and procedure presented in the preceding paper. The activity of the solvent is...

Theory of Molecular Size Distribution and Gel Formation in Branched‐Chain Polymers

The most probable distributions of molecular sizes are calculated for certain types of branched‐chain polymers. The results represent an extension of the previous work of Flory, who showed that very large polymeric molecules appear suddenly at a critical...

Statistical Mechanics of Cross‐Linked Polymer Networks I. Rubberlike Elasticity

A model is proposed for the structure of a cross‐linked network, such as exists in a vulcanized rubber, which is amenable to statistical treatment. Expressions are derived for the structural entropy of the network, and for the entropy change on deformation....

Description of stress-strain curves by three parameters

A simple formula is suggested for describing the stress-strain curve in terms of three parameters; namely, Young's modulus and two secant yield strengths. Dimensionless charts are derived from this formula for determining the stress-strain curve, the...

Theory of the Elastic Properties of Rubber

Previous discussions of the kinetic theory of rubberelasticity have dealt with individual long chain molecules, but the theory of the structure of bulk rubber has been almost entirely undeveloped. The present paper goes beyond earlier ones both in the...

The Asymmetric Rotor I. Calculation and Symmetry Classification of Energy Levels

A table of energy level patterns for rigid asymmetric rotors is given, by means of which this approximation to the rotational energies of all molecules up to J = 10 may be readily evaluated. The symmetry classification of each level is determined and...

The Interpretation of Voting in the Allocation of Economic Resources

Individual goods and social goods compared, 27. — Quantitative measurement of social goods, 28. — Ideal output of social goods, 30. — Individual voting on outputs, 32. — Individual voting on increments to existing outputs, 40. — Alternatives...

Mechanical Properties of Polymeric Materials

A molecular model in terms of which the elasticviscousproperties of rubber‐like substances can be interpreted is presented. Experiments on stress relaxation at constant extension, creep under constant load, extrusion, vibration, and breaking are discussed...

THERMODYNAMICS OF SOIL MOISTURE

Dynamical friction. I. General considerations: the coefficient of dynamical friction

In this paper it is shown that a star must experience dynamical friction, i.e., it must suffer from a systematic tendency to be decelerated in the direction of its motion. 'This dynamical friction which stars experience is one of the direct consequences...

The estimation of creatine and of diacetyl

P. Eggleton, S. R. Elsden, Nancy Gough

The Surface Recombination of H Atoms and OH Radicals

A diffusion method of investigating surface recombination of atoms by substances of low catalytic power is presented. By this method we have evaluated the coefficient of recombination γ for H and OH on Pyrex for a temperature range of over 500°C. For...

The Influence of Hindered Molecular Rotation on the Dielectric Constants of Water, Alcohols, and Other Polar Liquids

The theory of dielectric polarization of polar liquids is used to calculate the dielectric constants of water and some alcohols. Quasi‐rigid coordination models, based upon x‐ray structural investigations, are employed in the calculation of a function...

ELECTROENCEPHALOGRAPHIC CLASSIFICATION OF EPILEPTIC PATIENTS AND CONTROL SUBJECTS

The clinical application of electroencephalography is complicated by the wide range of individual patterns encountered in the most carefully selected control groups and by the fact that almost all patterns which might be used for diagnosis can be found...

The Ploughing and Adhesion of Sliding Metals

Studies of the surface damage caused by the sliding of clean metals on one another show that penetration and distortion occur to some depth beneath the surface. Micro‐examination shows that welding of the metals takes place quite readily even at low...

PAROXYSMAL VENTRICULAR TACHYCARDIA.

W. Trevor Cooke, Paul D. White

Breakdown of Thixotropic Structure as Function of Time

Measurements of the thixotropic breakdown of structure with time of agitation were performed at different rates of shear on a number of pigment suspensions and on various oils in a rotational viscometer. The product of rate of breakdown in thixotropic...

Menarcheal age and the height, weight, and skeletal age of girls age 7 to 17 years

SummaryThis report is based on 1,339 birthday examinations of 200 Brush Foundation Regular Series girls from 7 to 17 years of age. The data used are menarcheal age; measurements of standing height and weight; skeletal age assessments made according to...

STUDIES ON THE HEMORRHAGIC SWEET CLOVER DISEASE XI. HYPOPROTHROMBINEMIA IN THE RAT INDUCED BY SALICYLIC ACID

A Comparison of the mammalian and reptilian tecta

G. Carl Huber, Elizabeth Caroline Crosby

Patency of the ductus arteriosus in adults

1. 1. Brief notes are given on 57 adults, with post-mortem examinations, who had simple, typical patency of the ductus arteriosus. A few data are presented on 10 adults with atyical patency of the ductus arteriosus.2. 2. Case reports are presented on...

Post-partum observation of pelvic tissue damage

A method employed recording in an anatomical order pelvic tissue damage due to parturition is presented with a preliminary report of figures showing damage to the various planes and regions. Hazards in accurately observing damage are recognized, particularly...
