TOPIC TAGSs uranium, titrimetry, organic solvent
ABSTRACT: Sakharov's method of deterviining uranium (VI) in the aqueous phaso, iii-
volving reduction with Mohr's salt to U(IV) in phosphoric acid solution then titra-
tion with ammonium vanadate in the pr"m-ence.of sodium diphenylsulfonate until a
stable violet color appears, was applied by the authors to the determination of
uranium in organic solutions. The endpoint was determined with r, "Titrigraph" re-
cording cosapensograph over a range of' 1.x 10-1-3 x 10-5 mol/l. The effect of the
following factors on the accuracy of tho anAlysis were studied: purity and quanti-:
ty of Mohr's salt, duration of boiling of the solution during reduction, amount of
phosphoric acid, and time elapsed between the end of oxidation and start of titra-
tion. Tho possiblilfty of determining uranium was studied in aqueous solutions and
kerosine, ethyl other and othylacetatdg and also in the following extracting agents

ABSTRACT-. The author discusses the equipment needed and some of tho problems to b~
overcome for a manned trip to the moon. Since a moon spaceship would have to ac-
celerat , maneuvers and decelerate several times during the round trip, the weight
of tho fuol it would have to carry initially would make the ship too heavy -- over
15,000 tons - to launch from earth. The solution is to assemble the apacoship from
components launched separately into an earth orbit and joined in space, The round
trip shoUd take about ton days, and three astronauts would be needed to man the
ship. A spaceship of this type, with a 3-4= crew. would need 40.8 Ulograms of

-food, 95 kilograms of water, 47.5 kilograms'of oxygen, and about 470 kilograms of
air conditioning and power generating equipment. In addition, there would be 2211
kilogrwas of other equipment, 454 kilograms of instruraents and gauges, radiation
and meteor protection devices, etc. According to this project, total weight of the
spaceship, not including motors and fuel reserves, would be 13.4 tons. Other pro-
jects, which call for a landing on the moon, estimate the total weight at between
50 and 70 tons. One of the main problems with ~,.tgard to a moon flight is the rad-
iation belt. 7his is now being studied by means of the two Soviet satellites,
Elektron 1 and Elektron 2, placed in orbit on 30 January 1964. Another problem Is
that of the moon's environment, 7he American satellite, Ran-or 6, also launched on

30 January 1964, iras supposed to take photographs while descending for a landing on
tho noon. Because of a malfunction, however, none of the six cameras aboard the
satellite worked. 7he sending of other measuring instruments to thq moon is being
cont(rplated. It as now impossible to &V.vbon man will first land on the moon,
According to a recent alltement of the Soviet prof6se-or 0. Pokrov3ki, "the next
step in the development of astronautics will be a manned landing on the moon (after
low-altitudo flights around the moon and return trips to the earth). TUs must be

TEXT: The article describes a method of measuring the complex permeability
and permittivity of ferrites at frequencies ranging from 200 to 5,000 Yj-
This method is based on the use of the coaxial measuring standard and
is of great help in establishing the technologi,~al processes necessary for
studying the properties of ferrites within the above-mentioned frequency
intervals. This paper deals only with,*.,and Fof the sample, because these
are the results of measurements, and because they can be used for making
the necessary corrections. The stationary-wave method permits the deter-
mination of,4 and r-, if the characteristic impedance, Z, of the test sec-
tion. of the coaxial line, and the wave propagation complex constant,'f,
within the section are known. This calculation is obtained from the

z and,(, it is necessary to accomplish two, or even three measurements of
the input impedance, for two or three different positions of the sample
in the measuring line. z and -r may then be determined according to one of
the following methods: (1) the mpthod of measuring the input impedance,
the sample bein.6 in the no-load and short-circuited condition, worked out
by J.B. Birks zuef 5s Proc. Phys. Soc. 60, 1948, 2821; (2) the method of
the three reactive loads, recommended by I. N. Kolli and K. M. Polivanov
ZRef 6: Izv. Ak. Nauk USSR, 1954, no. g; and (31 the method of the two
identical samples, worked out by E. B. Zaltsman ZRef 7: Izmeritelnaya
tekhnika, 1957, no. Y. Since these methods are fairly complicated, the
author suggests measuring the input impedance inside the section which
disconnects the sample from the rest of the line when this is short-
circuited even beyond the sample, as shown in Fig-la, and measuring the
input impedarce within that section, when the line is short-circuited at
a distance g, subsequent to the sample, as shown in Fig.lb. Thus, a single
sample of the material studied has to be used and the two positions to be
measured are easily achieved since g is constant over a large frequency
interval. The input impedance of the condition shown in Fig.la is given
