The general expression for this coefficient is 1,0 (r., Q.

A formula is derived for the asymptotic value of 0 determined by the physical properties of the shielding material alone. A comparison of theoretical and experimental asymptotic values of 0 shows a systematic divergence by a factor of approximately,2.5, the theoretical data being overestimated. The reason for the divergence is assumed to be inaccurate deter- mination.of neutron intensities at the boundary. In spite of the discrepancy between experimental and theoretical data, the nearly constant divergence obtained for various elements with large, small and moderate capture cross sections (tungsten, lead, iron and nickel) indicates that the proposed method may be used for calculating the asymp- totic values of 0 with an accuracy of 30% if a correction factor of 2.6 is used.

The function f(x) was experimentally. studied by introducing a hydrogen-containing substance into a nickel screen made up 4f sheets measuring 80x8OxO.8 cm for an overall thickness of 25 cm. This specimen was surrounded by a neutron shield for reducing the background. A single-crystal scintil- lation gamma-spectrometer with a crystal,of sodium iodide was used for measuring the number of capture y-quanta with an energy of greater than 7 Mev produced by radiation capture of neutrons in the nickel. Curves are given showing neutron hazard functions iwith respect to capture y-radiation. These functions describe the contribution of neutrons to the stream of y-quanta behind the screen as a function of the neutron ienergy and inlet coordinate. The results show that the addition of hydrog,?n-containing :material through nearly the entire thickness of the nickel layer increases the inten- Card L 65057---67 rXCC NR.

An exception to this rule is the first 1 6 cm of nickel where the neutron hazard function for low energy particles is less than the function for high energy neutrons so that a good moderator placed at these points Ireduces the intensity of capture y-quanta behind the screen.

The damage caused by the caterpillars in the forests of the Pribaykal region and the Chita Oblast- from 1,049 to 1952, and in the Tomsk Oblast: in the Chulym river basin and the Krasnoyarsk Kray from 1950 to 1956, grew to dimensions of a 10;rov disaster. An estimated 8 million ha of forests2 consisting of 30% spruce, 25%.fir, 30% cedar, 15 to 20% birch and aspen and small amounts of pine, coniferous trees of an average 140 to 180 years with a yield of 200 to 250 cu m per ha, were devastated. In addition to this, rot and the spruce longhorn Monochamus urussovi, with 40 larvae per running meter, threaten additional forest expanses. The huge .losses are acutely felt by the forest economy, the railroads, pencil factories and-all industrial branches depending or. Card 1/3 wood supplies. Losses, especially of cedar, spruce and fir Care for Forests 26-58-7-9/48 trees, endangered the food basis for fur-bearing squirrels, martens and several wild fowl. Although the Glavnoye uprav- leniye lesnogo khozyaystva i polezashchitnogo lesorazvede- niya Ministerstva sellskogo khozyzystva SSSR (Main Admini- stration of the Forest Economy and Farmland-Protecting Forest Cultivation of the USSR Ministry of Agriculture) has known of the danger threatening these forests since 1949/50 and studied the biology of the peat, the measures.taken at last were too late and ineffective. When insecticides were spread from the air in the Tegulldet ~-Rayon ~. in 1956, the number of caterpillars per tree had already amounted to 40,000- Since it is estimated that the poison kills about 95%, the remaining 5% or 2,000 caterpillars a tree suffice to finish off the forests. It is important to recognize from the very beginning the activities of forest-pests. Therefore, the Forest Group of the Laboratory of Air Methods of the AS USSR in 1957 developed a method of spectrozonal air photography of the forests infested by the Siberian silkworm and a second method of ensuing interpretation and evaluation of these photographs. The experimental photos were made on 5.types of air photography films, the pan- Card 2/3 chromatic T-10-600, the orthochromatic RF-3, the infra- Care for Forests 26-58-7-9/48 chromatic 1-760, the spectrozonal two-layer SN-2 and the three-layer color TsN-l- The spectrozonal SN-2 film in con- nection with an orange OS-14 light filter proved to be the most suitable combination for the purpose of recognizing by color shades the SpOtB of deciduous and coniferous, in- fested and non-infested trees on the air photograph of a vast forestscape.

Mashinostroyeniye, no. 1, 1966p 158-163 TOPIC TAGS: porosity, porous metal, powder metal ABSTRACT: The average size of pores is one of the important characteristics of porous media determining the filteling properties of porous media and the hydraulic resista;nZe in the filtration of fluids and gases through pores. Consequently, the '%uthor vestl tes the determination of average dimensions of pores of sintered porous metals/kade of spherical A puticles (bronze) and particles of arbitrary form (nichrome, stainless steel.

Expe:-ixnental data presented in the article concerning the average size of the pores were obtained by squeezing liquids through the pores, by microphotographic methods, and by the ijimultaneous solutions of two equations. An analysis of the results shown that the values of average pore dimensions are influenced by the size of the particles, the porosity, L__qETd 1/2 UDC: 621.9-496 -I.. I.
