The initial retention of implant-supported removable partial
dentures(ISRPD) is unknown. the purpose of this in vitro study was
to compare maximum dislodging forces of distal extension
mandibular ISRPD with three different clasp design. a stimulat
ed
class 1 partially edentulous mandible was prepared with two
implant in the first molar regions and two metal ceramic on distal
abutments. Fifteen bilateral distal extension frameworks was
fabricated with three different clasp design (Akers, I bar clasp ,no
clasp),each specimen was subjected to three type of retention
pulls ( main ,unilateral ,posterior pulls) five time with universal
testing machine.
This study aims to examine factors influencing the customer switching behavior in the Syrian banking sector, as this is the first study of its kind in the Syrian Arab Republic. This study will help the departments of banks to understand the factors t
hat drive customers to switch their banks to another and develop strategies that help reducing the proportion of the switching they have.
With the advent of Experimental Psychology in the middle of the last century and
took control of scientists on the research and studies that have appeared in that period,
which was on the whole attempt to find and understand the cognitive processes
taking
place during the learning and performance of the studies that appeared in that period, and is
a model unique to the relationship between cognition and motor performance Contextual
Interference that have received since the appearance of the many studies that have proven
the effect of overlapping content is that some of the results did not demonstrate this effect,
scientists these results are attributed to the nature of the tasks and subject to the influence
of one general motor program.
This research is an applied study of overlapping content adopted in his experience on
the skill of the correction in basketball from different points in order to verify or deny the
impact of the emergence of overlapping content in skills which are subject to the influence
of one general motor program.
Find showed the impact of the emergence of overlapping content in skills which are
subject to the influence of one general motor program, the results of which is a pilot for the
use of unconditional support for overlapping content by teaching motor skills.
The study was carried out to show the effect of the clay characteristics:
specific surface area (Ss), cation exchange capacity (CEC), and the assemblage
of clay particles on the soil water content. The effect of hydric stress history
(wetting and
drying cycles) on the water content of soil was also investigated.
Soil samples comprising topsoil horizons and subsoil horizons, with a clay
content > 30% were collected in several regions of France and Syria (2009 -
2012) in cooperation with the National Center for Scientific Research and the
University of Orléans in France to study the effect of physical characteristics on
the fertility status of the soil. The water retention properties were studied from
(0.01) bar to (15) bar water potential using small clods collected in winter when
swelling is at a maximum and water content close to field capacity. The clay
content, the bulk density of horizon and clods, the cation exchange capacity and
the specific surface area were measured. The X-ray diffraction (XRD) was used
for identification of the main mineralogical phase, and to study the relationship
between the clay mineralogy and the water retention. Results showed that the
variation of the soil water content was explained by the differences of clay
content and the clay fabric (assemblage of clay particles). The results also
showed that wetting and drying cycles were the most important and critical
factor for soil water retention properties relative to the other evaluated factors.
We present in this paper a graphical study of regions of thermally deposited
ZnS thin films on glass by atomic force microscope (AFM). This study consists
of volume parameters and functional parameters of these films surfaces for the
object of inv
estigating the possibility to retain fluids by these films. For doing
so, we registered Abbott-Firestone curves that are based on height distribution
for these films, we measured volume and functional parameters in the whole
pores. Using the thresholding operator we followed parameters distribution in
depth of the surface. At the end we compared these parameters by the results of
another study based on slice selection at different levels.
Ready made post design plays an important role with resin cement ability on
post retention in to the root canal. While the paraposts are the most retentive.
To compare the resistance of serrated Para post, tapered-smooth, and threaded para posts, c
emented with
panivia21 to transverse load.
Most of previous studies used tensile or pressure forces (as parallel to tooth
long axis) to study the cemented posts resistance, But there are lateral forces tried to loosen, or bending
those posts.
Aim of study: detecting the resistance of Ready
- made Serrated- para Posts cemented by three different
Luting Cements to BendingMoment by applying a horizontal force on the free post end.
