EROSIONAL DEVELOPMENT OF STREAMS AND THEIR DRAINAGE BASINS; HYDROPHYSICAL APPROACH TO QUANTITATIVE MORPHOLOGY

The composition of the stream system of a drainage basin can be expressed quantitatively in terms of stream order, drainage density, bifurcation ratio, and stream-length ratio.Stream orders are so chosen that the fingertip or unbranched tributaries are...

Free Volume and Entropy in Condensed Systems III. Entropy in Binary Liquid Mixtures; Partial Molal Entropy in Dilute Solutions; Structure and Thermodynamics in Aqueous Electrolytes

The ideas of the first and second papers in this series, which make it possible to interpret entropy data in terms of a physical picture, are applied to binary solutions, and equations are derived relating energy and volume changes when a solution is...

The Statistical Thermodynamics of Multicomponent Systems

Distribution functions,F n(z, {n}), for multicomponent systems are defined proportional to the probability density that n molecules in an infinite isothermal system of fugacity set z will occupy the configurational coordinates symbolized by {n}. All thermodynamic...

Interaction with the absorber as the mechanism of radiation

"We must, therefore, be prepared to find that further advance into this region will require a still more extensive renunciation of features which we are accustomed to demand of the space time mode of description." — Niels Bohr.

Information and the Accuracy Attainable in the Estimation of Statistical Parameters

The earliest method of estimation of statistical parameters is the method of least squares due to Markoff. A set of observations whose expectations are linear functions of a number of unknown parameters being given, the problem which Markoff posed for...

The Principle of Corresponding States

The principle of corresponding states in modern form has been applied to the following properties: the critical state, the virial coefficient, the Boyle point, the densities of coexistent phases, the vapor pressure of the liquid, the entropies of evaporation...

Convection Currents in a Porous Medium

The problem is considered of the convection of a fluid through a permeable medium as the result of a vertical temperature‐gradient, the medium being in the shape of a flat layer bounded above and below by perfectly conducting media. It appears that...

Cyanosis in Infants Caused by Nitrates in Well Water

Two examples of a previously unrecognized condition which may be confused with congenital heart disease are cited in this report. The condition may occur anywhere in rural areas where well water is used in infant feeding.REPORT OF CASES Case 1.— C....

The Cascade Impactor: An Instrument for Sampling Coarse Aerosols

A new instrument is described which will sample windborne and stationary aerosols such as natural fogs and clouds, fine sprays, insecticidal mists, coarse dusts, pollen and spores, etc. By means of four progressively finer jets impinging on glass slides...

EFFECTS OF OXYGEN AT INCREASED PRESSURE

Volume 25, 1945. Paper by J. W. Bean: Effects of Oxygen at Increased Pressure. Page 69, 2nd paragraph, line 14, which reads “...137.5 + (3 x 360) + 1226.5 ...” should read “... 137.5 + (3 x 360) + 9 = 1226.5 ...”

The Statistical Theory of the Strength of Bundles of Threads. I

A group of parallel threads of equal length, clamped at each end so that all threads extend equally under tension, is called a bundle, and the maximum load which the bundle can support is called its strength. The object of the work is to study the probability...

A manual of the Aspergilli.

The idea of nature

R. G. Collingwood

The philosophy of the tooth positioning appliance

It is not necessary or desirable to treat every case of malocclusion that is presented. Many, if not most, of these children of 3 to 6 years can be safely put under observation in order that the tendency of growth can be noted. A fair percentage will...

Definitive equations for the fluid resistance of spheres

For calculation of terminal velocities it is convenient to express the Reynolds' number, Re, of a moving sphere as a function of the dimensionless group ψRe2, where ψ is the drag coefficient. The following equations have been fitted by the method of...

Summary of Airfoil Data

The historical development of NACA airfoils is briefly reviewed. New data are presented that permit the rapid calculation of the approximate pressure distributions for the older NACA four-digit and five-digit airfoils by the same methods used for the...

BACITRACIN: A NEW ANTIBIOTIC PRODUCED BY A MEMBER OF THE B. SUBTILIS GROUP

A new antibiotic "bacitracin" has been recovered from a strain of the B. subtilis group of organisms. It is neutral, water-soluble, non-toxic and relatively heat stable. In vitro it is active chiefly against Grampositive organisms, but the gonococcus...

TRANSIENT TACHYCARDIA: PROGNOSTIC SIGNIFICANCE ALONE AND IN ASSOCIATION WITH TRANSIENT HYPERTENSION

The rate of the heart varies widely in normal persons and may be increased temporarily by many different causes. Among them are excitement, exertion, pain, the ingestion of food, the drinking of coffee or tea and the smoking of tobacco. Acceleration is...

THE PETIT MAL EPILEPSIES: THEIR TREATMENT WITH TRIDIONE

The specific relationship of age to the seizures of epilepsy has been inadequately set forth. Seizures of course may begin at any age between birth and senility, but the incidence of various types of seizures and of various patterns of electroencephalographic...

A study of orthodontic anchorage possibilities in basal bone

In each of five dogs a screw of vitallium was placed in the anterior border of the ramus of the mandible, one side on each dog. Traction was applied to the screw by means of an orthodontic elastic connected to a maxillary appliance. All of the screws...
