Use and design considerations of sprinkler systems in Colorado

CER47-52WEC39.May 2, 1952.Sprinkling can be used advantageously in Colorado to irrigate rough or uneven lands where surface irrigation would be difficult or unsatisfactory. It is useful on lands that cannot be properly prepared for irrigation because of thin top soils underlain by gravel or hardpan. Most of the hazards of erosion on many of our steep slopes are avoided by sprinkling. A better cover crop can be grown in orchards and root injury by furrowing out tools is eliminated. Light irrigations can be effectively applied by sprinkling and, especially on light textured soil, a considerable saving of water is possible. Sprinkling offers a very valuable alternative method of applying water but its greatest economic value probably lies in the development of new lands. The high capital cost of equipment can about equal the cost of preparing land for surface irrigation in many cases. Practically no land preparation is necessary under sprinkling. Cost of power is of sufficient importance that it should be given serious consideration in making a choice. The design of a sprinkler system should not be attempted by the inexperienced. It is an engineering problem in which the engineer should have a knowledge of soils and plants

Mass-loss rates of Very Massive Stars

We discuss the basic physics of hot-star winds and we provide mass-loss rates for (very) massive stars. Whilst the emphasis is on theoretical concepts and line-force modelling, we also discuss the current state of observations and empirical modelling, and address the issue of wind clumping.Comment: 36 pages, 15 figures, Book Chapter in "Very Massive Stars in the Local Universe", Springer, Ed.

Theory and Applications of X-ray Standing Waves in Real Crystals

Theoretical aspects of x-ray standing wave method for investigation of the real structure of crystals are considered in this review paper. Starting from the general approach of the secondary radiation yield from deformed crystals this theory is applied to different concreat cases. Various models of deformed crystals like: bicrystal model, multilayer model, crystals with extended deformation field are considered in detailes. Peculiarities of x-ray standing wave behavior in different scattering geometries (Bragg, Laue) are analysed in detailes. New possibilities to solve the phase problem with x-ray standing wave method are discussed in the review. General theoretical approaches are illustrated with a big number of experimental results.Comment: 101 pages, 43 figures, 3 table

Astronomical Distance Determination in the Space Age: Secondary Distance Indicators

The formal division of the distance indicators into primary and secondary leads to difficulties in description of methods which can actually be used in two ways: with, and without the support of the other methods for scaling. Thus instead of concentrating on the scaling requirement we concentrate on all methods of distance determination to extragalactic sources which are designated, at least formally, to use for individual sources. Among those, the Supernovae Ia is clearly the leader due to its enormous success in determination of the expansion rate of the Universe. However, new methods are rapidly developing, and there is also a progress in more traditional methods. We give a general overview of the methods but we mostly concentrate on the most recent developments in each field, and future expectations. © 2018, The Author(s)
