Experiments on the immunological characteristics of the vaccine were carried out on white mice 2 weeks old. It was stated that the formalin vaccine, precipitated with aluminium -hydroxide (I.R. -index of resistance - 105) was the most effective and ether vaccine (I.R. - 16) the last effective. The addition of 0.2576 phenol to the formalin vaccine did not decrease its antigenic properties (I.R. - 44). The immunity of vaccinated mice was proportionate to the amount of antigen intro- duced. Further experiments, cvrried out on volunteers (immunization with vaccine containing 57o of infected brain tinsue of mice 0. Ile for malln and 0. 2576 phenol) showed an Increase In - 1rus-neut.-alizing antibodies In the majority of those vaccin- ated after a repeated of vaccine. The highest concentration of antibodies was observed in the blood of subjects vaccinated for the third time within two months of the Irdtial one. References 13.

In 1935, 336 new popu lation cent res were added to the list of mass outbreaks. A high Incidence of spontaneous virus infection of the tick Nodes persuicatus (up to 40%) was. found in certain areas, where about 870/a of the population became infected. In certain regions a neuroinfection which is related to spring-summer encephalitis has been observed. This is the so-called two-wave meningo- encephalitis or milk- fever. The agent is a neurotropic virus carried by the tick Nodes ricinus and 1. persulcatus, however, in certain cases the infection is milk-borne originating from goats. A vaccine has been prepared from chick embryos which shows specific antigenicity and immunogenic properties agaiLlSt tick encephalitis. Anigstein -Galveston, Tex. (XX,6,8,17) X:_f gZW USSR Virology.

In the culture of Crocker sarcoma calls, the calls lost some of their ability to grow on the surface and to cause the formation of tumors when live animals were inoculated. In the culture of Ehrlich ascites carcinoma cells, a de- crease in metabolic activity was observed after the interaction of dancer calls with the viruses. The interaction between the various viral strains and cancer calls after subcutaneous and intraperitoneal- Inoculation caused active multiplication of the virus and affected the proliferative capacity of the infected cello. The Oriental strain of encephalitis virus multiplied most rapidly, and was able to penetrate .brain tisnue after inoculation into an ascites carcinoma. Under iden- tical conditionag the less usurovirulent TR-21 strain did not spread .beyond the tumor into which it was injected# Orig, art, has: I figure -and 1 table, (W& A, 501 SUB CODE* 06/ SUBM DATEs 06F'eb66/ ORIG RM 004/.,,,OTH REFt 006 Card 2/2 LNUUVICII, Tu.I.

The wolframite encountered for the first time was in foliated pieces with black, nontransparent grains. Some pieces had, however, dark red and red color, ranged from nor-transparent to almost transparent. In some instances, the wolframite was found in combination with the quartz, and in separate instances in combination with the arsenopyrite. The majority of grains were within 0.6 - 0.1 mm, some reached a size of 2 - 3 mm. The chemical examinat- ions made by B. V. Myrs'ka table 1), and the x-ray examinat- ions made by A. 0.

The dump car con- sists of a hood, bottom platform, unloading mechanism and the carriages. The hood has three transverse End two lengthwise edges welded into one stable spatial structure. The unloading mechanism has the following basic parts: 36 kw electric motor, the main reducer, two auxiliary reducers, and three 'Lifting screws. The capacity of the hood is from 33 to 35 cubic meters. Unloading takes 70 seconds and may be Pk~rformed by one man. There are 2 photographs. AVAILABLE: Library of Congress Card 1/1 1.

The author of the present article has designed a new type of dump car which unloads not by tilting, but by shifting the walls of the vehicle over the bottom, as is hown in Figure 1 and 2. Its main parts are: 1) the walls; 2) the bed; 3) the unloading me- chanism, and 4) the undercarraige. The technical cha- racteristics of the new type are as follows: weight - 22 to 23 tons;,the weight of load - 60 tons; the capacity of body - 33 to 35 cu m; height - 2,860 mm; width - 3,600 mm; lengths (between the axes of automatic couplings) - 9,480 mm; unloading time - 70 sec which can be reduced to 20 or 30 sec by applying more powerful electric motors Card 1/2 and a lower gcar ratio. The unloading mechanism shifts 127-58-5-13/30 A Dump Car With a Laterally-Moving-Walls Body for Unloading the walla of the dump car over its bed at a rate of 0-03 M/sec. The walls, shifting over the bed, form a slit up to 3,000 mm. wide, through which the load is pushed out. Such an experimental car was manufactured in the central electro-mechanical shops of the trust "Kanskugoll". It was tested in the Irsha-Borodino open pit in 1957. Tests were carried out under all temperatures. The unloading performance was satisfactory, and took less time thin that of conventional dump cars. The frozen rock is scraped from the bottom of the car by the back wall of the body. There are 3 photos, 2 figures and 1 table.

Orig Pub : Zh. eksperlm. i teor. fiziki, 1956, 31, No 2, 36o Abstract : The relative cross sections of the (n,p) reactions on isotopes of Zr, Cd, Ti, and Sr, and Ca were measured by analysis of the curves of nuclear decay vs. reaction products. From the data obtained and from the analysis of the data by Pauli and Clarke '(Referat Zhur Fizikaj 1955J. 8684) on the cross sections of the (n,p) reactions on iso- topes of Mg, Si, 8, Zn, and Ge, the author draws the fol- lowing conclusion: (1) The cross sections of the (n,p) Card 1/2 MM/Nuclear Physics Abs Jour Ref Zhur - Fizika, No 5, 1957, 1.1214 reactions on nuclei with several isotopes are reduced substantially with increasing weight of the isotopes. This reduction is greater for the lighter nuclei. (2) In light nuclei, an increase in the atomic weight by two units reduces the cross section to one quarter (Ca, Si, S, Zn) or to 1116 (Mg, Ti), vhile in heavier onee the reduction is to one half (Sr, Zi, Cd, Ge). (3) The results obtained apparently contradict the statistical theory and possibly are evidence of the retention of the shall structure even at high excita- tion energies.

TITLE: The Isomer Pd 111AI (Izomer Pd Russian). PERIODICAL: Doklady Akademii Nauk SSSR, 1957, Vol 113, Nr 4, PP 773 - 776 (U.S.S.R.) ABSTRACT: First of all the authors give some information on relevant preli- minary papers. It is the aim of the paper under review to demon- strate unambiguously that the 5.5-hours palladium activity belongs to a certain isotope or isomer of the palladium. For this purpose, experiments were carried out with regard to the radischemical se- parati*n of isomers in the mixture of the radioactive isotopes of palladium which are produced at the reactions Cd(n,a) and Pd(n,2r The method of the chemical separation of the nuolear iaomera is based on the Szilard-Chalmera phenomenon. When working on the me- thoda for the apparation of the palladium isomers, the authors of the paper under review tried reagents: dimethyl glyoxime, aceto- xime, salicylic aldoxime and a-nitrose-p-naphtel. The beat results were obtained with salicylic aldoxime. Salioylic aldoxime is suited for the separation of the nuclear isomers of palladium.

The experimental arrangements are discussed. In the mixture of the radioactive palladium isotopes produ ilia' t the reactions Cd(nva)iPd there is mtained the isomer Pd which is genetical- ly connected with Pd (T-22 min.). The Identification of the H11141 (N5.5 hours) in the Mizture of the Radioactive Palladium Isotopes which were produced at the reactions Pd(n,2r): The corresponding experiment, fturibed in the paper under review proved the producti*n of Pd with T-5.5 hours aftellfhe reaction Pd(n,rjjland also its genetic composi- tion an Fd (T-22 min) and Ag (T67.5 days).
