Abstract : Experimnts were conducted to determine the equilibrium in a Co(NO?)2 Ni
(N6?)2 - H20 s:rstem at 2CP. The results obtained are tabulated. I was found
tha the components of the system are isodimorpbous at the above mentioned
temperature and two series of solid solutions are being forred in the system.
It was established that the system remains ideal in each of the two zones of
existence of a solid solution of specific structure. Three references: 2-

The factors deterWning the entrapment of the admixtures during
polythermal crystallization are explained as* the relative super-
saturation of the tiolution at each moment of crystallization and
the degree of crystallization of the basic substance toward the
conclusion of the crystallization process. The presence of two

TF-XT-. Information is given on results of*invedtigating pore formation in
welding beads onto AMg6 alloy plates with a wire of the same material and of
pure aluminum. It was found that pcres are formed in welding the AMg6 alloy, as
a result of a developed Interaction between the liquid metal and the moisture,
contained in the particles of the o)ide film; these particles are present in
the welding pool when the base and filler metal have melted. At a greater thick-
ness of the oxide film, the effect (of moisture may be inhibited until completed
crystallization stages. Then, besides pores of regular shape, which have par-
tially floated up to the surface, cavities of irregular, branched shape are
formed as a result of displacement )f eutectic by liberated hydrogen. Bulging

detectors. The importance ascribed to these devices was shown In the lecturee read
at the V~zkumn~ zhLvod P~emyskenl (Research Plant at P~emyslenl) and at the Conference
of the Dosimetrickh sekce VTS (Dosimetric Section of the Scientific-Technical Socie-
ty) on May 22, 1959. Introductory, the allthor describes and gives a schematic
diagram (Figure 1) of a scintillation detector, based on the suitable connection
between a scintillator, a multiplier, a photo-cathode, an amplifier, a discriminator,
and a registration device. A historical review follows, containing data on the
development of scintillation detectors, of new luminescent materials used in
detection of beta and gamma rays, of artificial naphtalene crystals, of aithracene
crystals, of artificial anorganic crystals (for example, sodium iodide a,:-~11,rated
by thallium and cesium iodide), of a series of organic luminescent substances sojved
in organic liquids or in plastic substances. Parallel to this photo multipliers

radiation Is the most important practical advantage of scintillation detec'~Cr_z,;
the efficiency is 30 - 60 times higher compared to the GM type counters: Pho-.~,_
graph 2 shows a scintillation detector for gamma radiation, developed and produced
by thp Research Plan-~ at P~emyhleni. Scintillation detertors with a probe of high
detecting efficiency for gamma radiatiot are applied in the following fields:
a) Observation of the function of the t~yrold gland using the radloa:t.4ve
iodine 131 (Photograph 3 shows the "Scintigrard' of the distribution of radioact,,ve
iodine in a healthy thyroid gland (a) and in a thyroid gland with tubercular
struma with hyperfunctional tubercle (b); b) Localization of cerebral tumors by
means of d1iodo fluorescein using a directional scintillation detector wilh a
lead-covered probe (Figure 4 shows schematic sections of d1rectional scintillat-1,M

developed, equipped with a cylindrical opening in the direction of the axle
(Photograph 5 shows a so-called fountainous scintillation detector). A precise
detection of gamma rays of a radioactivity of 10-10 Curie in one-minute measuring
intervals is made possible; the device is applied in detecting the radioactivity
of blood, urine etc. A description of various devices for the measuring of gamma
radiation, developed at the laboratories of the Universities of Los Alamos and
Harwell, follows. Small sized so-called needle-detectors are applied in the
determination of mammary tumor, using radioactive phosphorus P-32. In addition tl_N~
scintillation detectors serve for the protection of workmen against alpha-radiation;
in accordance with the regulations concerning workirgplaces exposed to radioactive
substances the contamination of the 1st and 2nd class working places should not
surmount the quantity of 23 disintegrations per min/cm2. Large-area scintillation
detectors are suitable for the testing of working places with regard to an alpha
ray contamination; they are equipped with a zinc-sulphide layer activated by
silver (see Photograph 6). So-called windowless scintillation detectors with a
detecting efficiency of 50% are applied for detection and spectral analysis (see
Photograph 7). Scintillation detectors are also used in detection of beta isotopes
c-14, S-35, H-3. The photomultiplier's noise impulses, deteriorating the performance

arrangement. Thus an effect of about 70% may be obtained detecting the isotope

Detcetion of actremely Low Gamma Activities With Scintillation De-
Jadernh energle,
TEXT: The article describes the basic parameters of scintillation detec-
tors used for the detection of extremely low gamma activities. The most important
prerequisites of such detectors are: (1) maximum sensitivity; (2) optimum geomet-
ric efficiency between the measured sample and the detection volume; (3) low back-
ground and minimum background fluctuation; (4) design that will permit measure-
ments of samples with sufficiently large volume with good geometric efficiency..
FNarthermore, the detector sensitivity, detector sensitivity threshold, and factors
influencing its long-term stability are defined, and the relations for the measure-
ment-time calculation for a desir.?d accuracy, for the evaluation of the detectors
in relation to their low-gamma-ac-.ivity measuring capability, and for the setting
of the optimum detector parametern are derived on the grounds of statistical con-
siderations. Four types of scint:-Ilation detectors for measuring liquid gamma

Fources are described, namely th-3 well-type, ring-cell type, beaker-type, and
immersion-typee. Their respectiva schematic diagrams are shown in Figure 8. The
well-type scintillation detectors feature the highest sensitivity and a nearly 4'iL-
-geometry. Their disadvantage is that the volume of the well restricts the volume
of' thp, measured samples to about 5 cm3. The ring-cell type detectors have a con-
siderably poorer geometric efficiency, by their design permits measurements of
samples up to 1 liter. Their disadvantage is also that the ring-cells have to be
custom-made for each crystal and lead-shield size. The beaker-type has a still
poorer geometric efficiency than the ring-call type detectors but standard beakers
can be used. Low, large-diameter crystals are best suitable for this type. The
in-marsion-type detectors have a geometric efficiency similar to that of the ring-
-cell type and are especially suitable for measuring gamma activities in large wa-
-ter reservoirs. The Tesla-Liberec n.p. - V~zkumnk zhvod (Tesla-Liberec, National
Enterprise, Research PlaiA) in F~e*gleni has designed the following 4 types of
low-activity scintillation detectors; (1) A well-type scintillation detector (Fig-
ure 9). It uses a probe with a 61 PK 411 photomultiplier tube and a cathode fdUow-
er, both produced by the plant, and an NaI (T1) crystal, 50 mm high, 45 W in di&-
meter with a well 37 mm deep, 1~) mm diameters capable of accomodating a 5 cm,3-sam-

ple. The probe is enclosed in a pear-shaped lead shield, which was originally de-
signed for a directional saintilLation counter also produced by the plant. The
electronic part comprises a high-voltage power supply, a pulse amplifier, a dis-
criminating circuit, and an evaluation unit. Samples are filled in mass-produced
vials, which are then inserted into the crystal well. (2) A ring-cell type detec-
tor using a standard NaI (TI) cr-rstal, 25 mm high, 33mm In diameter, and an "Uma-
plex" ring-cell with a maximum capacity of 4o cm3. (3) A beaker-type detector
(Fig. 15). It uses a standard MLI (T1) crystal, 25 mm hie~Al, 38 mm in diameter.
Standard "Sial 150" beakers are used which are placed directly on the scintillator.
The lead shield, probe design and electronics are similar to those of the well-type
detec!tor. (4) A beaker-type detector with a large NaI (T1) crystal (Fig. 'L6). It
consists of a lead casing, 270 mn high, 45 mm thick, in which a probe is mounted
with a 61 PK 421 photomultiplier and an NaI (TI) crystal, 45 am high, 90 mm in dia-
meter, grown in the chemical section of the plant. Radioactive solutions are filled
either into a mass-produced glass vessel, 120 mm in diameter, or into a 0.5 liter
bottle, 80 mm in diameter. Use of 2,000 cm3 bottles is also possible. From the--
oratical analyses and from exper-'mental results it can be stated that well-type 121
scintillation detectors can detect a minimum total activity of the order of 10- C,

TITLE: Approximation method for studying nonlinear conservative oscillations
SOURCE: Revue Rotimaino deg sciences techniques. Sorts do mecanique appliques. v. 11,
no. 2, 1966, 539-552
TOPIC TAGS: oscillating system, free oscillation, nonlinear vibration, approximatlon method
ABSTRACT: An approximation method Is proposed for studying oscillating systems that are
described by the equation of motion q + N(q) = 0. In this method, the region of oscillations to
divided Into subregions, In each of which the nonlinear characteristic N(q) Is replaced by two
billnear characteristics. Properly selected, the latter form continuous polygons. The singu-
lar point of the b1linear characteristics in each subregion Is determined from the condition that
the three characteristics are equivalent In terms of energy. Application of the polygonal charac
teristics to the determination of the amplitude and period of oscillations Is shown to provide
excellent approximation of the exact value. The method Is illustrated in application to systems
