This study focuses on studying the effects of Electric Field of deferent
frequencies (20Hz – 3MHz), on RBCs after being irradiated by (690μW) of He-
Ne Laser, with testing some blood characteristics like osmotic fragility,
Conductivity and Dielectric constant.
The aim of this research was to assess the physical, chemical،
microbiological and sensory characteristics of new made Qamar Al– stored for
six months and determine the effect of gamma rays on those characteristics.
Samples of Qamar Al–Din were su
bjected to sulfur fumigation and other
samples were left without sulfur fumigation and all samples were exposed to
four radiation doses (0, 1, 2 and 3 kilo Gray) and stored for 6 months at room
temperature (20° C). Results showed significant differences between sulfated
and non-sulfated samples in terms of pH, relative humidity, ash, total sugar،
viscosity, potassium, sodium, sulfur vitamin C and it was observed lower
microbial load. Results also showed that amount of vitamin C and viscosity was
significantly the highest in sulfated samples irradiated with 2 and 3 kilo Gray
and irradiation with a dose of 2 kilo Gray eliminated sufficiently the microbial
load. It was concluded that running this study is helpful to shed the light on the
importance of such these treatments especially that this traditional product
concerns large number of consumers and is exported to different countries in
the world.
In this paper samples of poly vinyl chloride PVC ,pure, irradiated
with Gama rays, were prepared by casting method in room
temperature and light, and under atmosphere pressure.
It was observed from this research that irradiation made real effect
on some of the studied optical properties, the irradiation increased
the transmittance while the electronic transitions kind remained
indirect before and after the irradiation.
Experiments were conducted to study effect of radiation and salt levels on plant
regeneration from callus for two cultivars of potato i.e. Riviera and Burren, under
in vitro condition. Results showed that the efficiency of radiation in induced
reg
eneration from callus in Riviera cultivar at salt level of (10 dS m-1) and Burren
cultivar at salt levels (8, 12 dS m-1). For the purpose of making sure inheritance
of salinity tolerant, mutant clones (plants induced from salt tolerant calli, which
planted at salt levels of 8, 10, 12 dS m-1 and plants induced from non salt tolerant
calli, which planted at salt level of 6 dS m-1) and their parental cultivars (Riviera
and Burren) by exposing to salt stress conditions and comparing them with control
(6 dS m-1). Results revealed that the lowest percentage of reduction in plant height,
number of nods per plant and tuberization were observed in salt tolerant mutants.
Plant height and number of nodes/plant can be considered as selective morphological
markers for in vitro salt tolerance .
