ABSTRACTt The photosensitizing capacity of A-carotene adsorbed an
alumina gel cir polyacrylonitrile has been studied to verify an
assumption that besides chlorophyll, carotene in vivo miRht act as
a sensitizing aRent of some intermediate photochemical reaction
occurring In the process of photosynthesis. The assumption was
made on the basis of the structural similarity of the carotene
molecule to nenattizers in photooraphy (tyanin dyea) and to the
photosensitive material of the eye (visual purple). In preliminary
experiments, it wee shown that $-carotene adsorbed on magnesia pro-
moted decoloration of thyeeine in the presence of ascorbic acid

extinction coefficient was measured during the process of gradual
docoloration of a methyl red solution containing ascorbic acid upon
illumination with blue liKht and in the presence of synthetic
B-carotene adsorbed on alumina Rel or polyacrylonitrile. Plots of
the absorption of light versus time show the photosensitizing capa-
city of the adsorbed B-carotene. The latter in a solution did not
show this caDacity. The mechanism of'phocosensitization of the
ph3tochemical reduction by adsorbed A-carotene is linked to its
behavior in the form of a complex with albumen in physiological
processes. Orig. art. hast 2 figures.

ABSTRACTS Chlorophylls n and 6 isolated from nettle leaves were adsorbed at 200C
from alcohol soluiions on activated magnesium oxide. The isothervas obtained showed
the adsorption of 6 til be almost twice that of a. Diffuse reflection spectra were r*-
corded with an SF-2W~~cordlng Voctrophotometer4O The plots of optical density v@.
surface concentration of the pigments were similar, although the optical density of
the chlorophyll o, monolayer was 9 hat higher than that of-i. The luminescence
spectra were taken with an ISP-_51 rt1pectrograph with a photoelectric attachment. Mea-
surements of the luminescence intensity as a function of the pi&pent concentration in
the monolayer yielded curves with a pronounced maxLmm at surface concentrations cor-
responding to the transition from the plane monolayer of pigment molc-ules to the lay-
er with edge orientation relative to the surface of the adsorbent. A snarp quenching

slower change of intensity was observed In chlorophyll 6 , despite the greater density
of the adsorption layer of this pigment. This fact is explained In terns of energy
transfer to nonlunineseent surface elements which leads to luminescence quenching of 1

to avoid passivation of the gold electrode, the potential
had to be increased rapidly (2.5 v/min). In the case of too

occurs, and the process is no longer limited by the diffusion
factors but by kinetic factors. There are 4 figures and 2

ABSTRACT: Ionization of oxygen was studied on rctalir,,~ -lisc electrodes of rhodium
(91). 7% P10. The discs had a 1.48 min radius and wote mourited in sets of four on a
platinized wheel having an outer radiu5 )I 1.8H mm and in inner radius of 1.76 mm.
Polarization curves were obtained in 0.1 N KOH solut'ons with the wheel rotating at
500, 1680 and 4020 rpm. On tile cathode si'le I
I he , urrent rose gradually with potential
;P until the oxygen was liberated at which point t~ie slope decreased. With increases
in rotation speed, the heights and slopes of t!,e cuives increased. 7'he C'ff-rent or, the
wheel and the %H202 yield are given as a flmctlori of disc potential for 500 and 1680
rpm. For increases in cathodic polarization of the discs, the current on the wheel

ABSTRACT: Ferroolectric elements used for brightness and Illumination time control must be
able to change their capacitance by at lewd a factor of 20 at comparatively low control voltages,
they must work at temperaturse within do -60 to +60C interval, have a working frequency
range from I to 20 kc, have a resistme of at least 1010 Obmv be mechanically stable, Mid
be hitmidity resistant. The commanly used (NH CH Cf)OH)3' HIS04 monocrystals have good
electxical properties, but have a low Carlo tem;?;~Ze (,-., 50C), are quite brittle, and must
be kept hermetically sealed. To overcosse dme sbwtcomings dw present authors prepared
baritun titanate polydamain crystals maids of cbemically pav WO and coodenser TiO .
Their operating temperature in frm -196 to +12*Cg effective W"-wity 35 - 40, re;;Give

ABSTRACT: The me!asurements were made on polycrystalline samples of
rectangular form, polarized in the dIrw3ction or the z axis. The
sample technology preparation was described elsewhere (?W v. 2, No.
8, 16810 1960). The alternating field was applied In the same-d1rec-
tion. The resonance and antiresonance frequencies of the longitudkal
oscillations excited in the samples were measured with the aid of a
heterodyne wave meter. The measurements were made by both static and

dynamic methods, with the piezoelectric modull. perpendicular to the
polarization axis (d 31 ) determined from measur,ements of 100 samples
of 30 compositions. The greatest piezoelectric modulus was found to
be possessed by the systems Ba(TI, Zr, Sn)o3 eM Ba(TI, 31, Sn)O 3 .
All ternary systems with ziroonlum and allicon were found to possess
similar piezoelectric properties, zirconium producing a somewhat lar-
ger piezoelectric effect than silicon. The strongest piezoelectric
properties wizre found to be when the percentages or Ti,, Zr, and Sn
were 0.65s 0.11, and 0.04 respectively for the zirconium and 0.9,
0.06, and 0.04 for the silicon. The plezomodull d for the ternary
31
systems were larger than for barium titanate. No noticeable differ,-
ence was observed between the results of static and dynamic measure-
ments. The static measurements were made on 15 systems of polycrys-
talline ferroelectrics with 55 different compositions. In addition,
the temperature dependence of the piezoelectric modulus d 31 on the
ceramic sintering temperature was Investigated, and was found to in-
crease with increasing sintering temperature, up to about 1450C,

annealing of the ceramic also exerts a strong influenca, since it
affects the character of the cryntalline phase. Orig. art. has:

TOPIC TAGS: dielectric capacitor, dielectric material, d1electric property, electrc-

ABSTRACT: The purpose of the investigation was to ascertain whether deformation In
an electric field and polarization are properties possessed by aLl dielectrics, and
role in electrostriction. The tests
which of these properties plays the dominatN
were made on commeycial cer!~Vc dielectricsWand on certain technical dielectrics such
as rubber, qurjtz,V Plexiglask Rochelle salt, and ADP. Altogether 166 sampler were
tested, 88 of-which were piezoelectric. The measurement consisted essentially of de-
termining the p.-ofile of the sample before and after application of the electric
field, and hence the change in sample dimensions, with the aid of a profile gauge
(IZP-17) accurate to 1.0 x 10-4 = at a vertical magnific&tion of 5200. 7be tests
have shown that all the measured dielectrics can be divided Into four groups, In
which the thickness of the sample (I) decreases or (ii) increases with applied volt-
age, (III) reversal of the voltage affects the change, arA (tv) at law voltage@ the
thickness first decreases and then with further increase in the field it begins to

increase. Tables of the relative changes in dimensions are presented. The results
confirm the correctness of the &sinmiption that electrostriction and polarization are
possessed by &U dielectrics. In the case of polycrystalline ceramics, the polariz&-
tion plays the major role, and the magnitude and direction of the electrostriction
are strongly dependent on the field. Tests were also made of the variation of the
rating of a capacitor under the influence of electrostriction, by applying to the
capacitor a dc field superimposed on a high-frequency (107 cps) field. These testa
have shown that with increasing appUed additional dc field, the capacitance increases
first and then reaches saturation or even decreases. Repetition of the tests under
different conditions has shown that, other conditions being equ&l, the capacitance
and the sign of the change depend on the composition of the ceramic and the technolo-
gy of its preparation. It In also shown that the change in the capacitance is due
essentially to polarization wid that the effect of electrastriction is negligible.

ABSTRACT: A trans4stor operating in the region of avalanche multiplication haa been
designed at the Ki7ev Polyt"chnical Institute for use as an inductive analog. The
alloyed-junction tfransistor, based an n-type germnium vith &-specific resistance of
0.18 ohm-cm, has been employed in a resonance simplifier circuit (see Fig. 1). The

acts as an analog +f the inductive element. in connect:d d parallel to resistor
Rk. Resistors R5 And R7 and potentiosete r R0 determine the operating conditions
of the transistor.- It was found that with an increase in the emitter current the
Inductance of the transistor drops while its Q increases; thus by varying the d-c
supply of the tran4istor the resonance frequency of the circuit can be shifted and
its Q controlled. For Q of the order 64 at a resonance frequency of 640 kc, resist-
ance in the emitter circuit of the PP. transistor was equal to 1.5 kohni, emitter
current to 1.7 samp. collector current to 2.1 samp, and collector voltage to -12 v.
In subsequent tests, resistance in the emitter circuit was equal to 22 kohm, emitter
current to 0.24 a W , collector current to 0.42 manp, and collector voltage to -15 v.
As a result of these wasurements the resonance frequency was fixed at 290 kc for
Q 30. For Q obov 100, the circuit at first because self-oscillatory and then acted
as a rectangular pulse generator. The two of Inductive avalanche translators will
make possible the Jesign of uintaturlsed resonance amplifier circuits as wall as
