2A05 5/089/61/011/006/008/014 Delayed-neutron yields in ... B102/3138 the number of delayed neutrons emittedi about 0.2 see; after irradiation had ceased the sample was dipped into a neutron detector 1.5 m from the neutron source. The detector consisted of 17 boron counters of the NM-5h (3NM-5A) type contained in a paraffin block. The end of neutron ,bombardment which coincided with removal of the sample vias established .AnembLtographically with an accuracy of 0.02 see. As neutron counting started 0.2 see after the end of bombardment, this caused a loss in neutrons with a delay of 0.16 sec. Special measurements were made to determine this error, which was not above the experimental level. The total number of delayed neutrons could thus be determined by extra- polating the neutron number - versus - time curve to the instant when bombardment ceased. The following results were found; totf" delayed- neutron yield decay event; 0.0130 * 0.0015 for Pu239, 4jid 0-075 -t 0.007 for Th The Pu239, yield is twice as high as when fission is induced by thermal or fission neutrons. This result is explained by assuming that neutron emission probability increases with increasing ex- citation energy. There are 1 figure and 4 references: 3 Soviet and 1 non-Soviet.

TITILE.~ The effect of-Ni on the fatigue strength of structural steel PMODICAL: Referativnyy zhurnal, Metallurglya, no. 1, 1962, 37, abstraot 11250 ("Wytrzymalo,so zmeazeniowa tworzyW i -'elementow metalow:~ch",, Warszawa, 1961, %--53, Polish summary) TEXT: The relation between 6~ and 6~ for 3 grades of steel with a diff6r- ent Ni content'(35XM, 34XBM and 33XH8MA),after,heat treatment was investigated. The..heat-treatment-consisted of oil hardening at-830 - 8500 C andAempering at 560 - 605~C with -oil cooling. Mechanical properties (6s, ej, 6.1,66, 83.. IV and elk) for all 12 investigated-heats are stated. The fatigue tests were c~;ried out,by three different methodst on plane samples - tension-compression,(I), on.p,lane cantilever samples- bending with torsion (II), on cantilever samples with a notch - bending with torsion (III). It is established that after the said heat treatment (q - 105 - 110 kg/mm2) 6w of investigated-steels Israther independent of the Ni content. For the method I 6~ - 48 - 49 ka/mm2, for the method II 6;x~ - 54 - 53 kg/mm2 and for the method III 6~. - 16 - 18 kg/mm2. For Card'1/2 j 33823 S/137/62/000/001/144/237 The effect of Ni on the fatigue strength ... A052/AIOI all 3 steels the relation of respective 6w and (51 is about-the same namely: 6~/6 - o.45o - o.454, 4118r, - 0.504 - 520, 6411 'o 144 - o.163, The notch sensitivity coefficient defAed as the relation is equal for all steels to 3.22 - 3.50. Consequently the addition ofwNi to steel for all parts working under cyclic load conditions is not justified. The application of steels with Ni is advisable for large cross-section parts where Ni is introduced to raise the hardenability. M.

Przegl. chir. 1956,2815 (501-506) After a discussion of the theoretical and clinical indications for epinephrectomy in cases of thromboangfitis obliteranis, the author comments on the short-term results obtained in a material of -16 patients operated on in the course of the last 2 years. Epinephrectomy was performed together with lumbar sympathectorny. Three caws are described. In one, with gangrenous changes in the limbs, the procedure had no effect on the morbid process. In the 2nd, with far-advancedchanges, an immediate cure was obtained. In the 3rd, changes appeared in the second limb after a lapse of 18 months. On the whole, better results were obtained than in patients who were subjected to sympathectomy alone. The author, discussing the operative technique, recommends examination of the adrenals in every case in which sympathectoiny is to be perform ed.

An increased blood pressure in the right posterior extremity was induced bN, the o1wrative inethod: the left iliac arterv was sectioned and then terminal-lateral anastomosis with the right external ifiac artery was rformed. In this way the blood pressure in the right femoral artery increased by r 0-30 mm. H9, while in the left artery (ligature) it decreased by 20-30 nim. I-Ig and in the arteries of the forelimbs it remained unchanged. Eight dogs were fed for 3-8 months with cholesterol and methylthiouracil. Arteriosclerotic lesions were found in 5 dogs. The intensity of lesions in the right iliac artery, femoral artery and aorta was similar. The arteriosclerotic lesions and their development are described.

A decreased sensitivity to herpesviruses -vias exhibited by cells treated with tannic acid prior to infection. The antiviral effect of-tannic acid is thought to be related to the poly- anionic natu're of the compound. 2 )lun(;arian, 28 Wstern references.

Abstract: [English article, authors' English summary modified] The effect of quercetin on different viruses has been studied. Herpesviros hominis, Ferpesvirus suis, type 3 of the parainfluenza virus and the Sindbis virus were found to be sensitive to quercetin. The sensitivity of type I poliovirus was moderate while types 2 and 3 of the poliovirus and types 3 and 4 of the adenoviruses were completely resistant. Being active only against the extra- cellular virus, quercetin was considered to have a virucidal effect. The effect of morin on Herpes suis was identical with that of quercatin while rutin was almost completely ineffective. 3 Hungarian, 14 Western references. [manuscript received 2?
