Supporting tunnel face by Fiber glass pipes technology is an effective method to
maintain the stability of tunnel face, thus reducing surface settlements, face deformation
and maintaining the safety of the workers and the mechanisms used in tunneli
ng.
This paper presents the results of finite-difference numerical analyses (FLAC3D program)
on the behavior of a shallow tunnel face reinforced by longitudinal fiber glass pipes. A 3D
numerical model has been calibrated and used to demonstrate the effectiveness of this
technique, and perform a parametric study to determine the critical reinforcements
parameters (the density (number of pipes)(A) and length (L)). The results indicate that the
face reinforcement technique using longitudinal fiber glass pipes can significantly reduce
the movements (face displacement and surface settlements), and thus improving the face
stability. These movements decrease by increasing the length of the pipes and increasing
the density of the pipes until reaching the critical density, and when we reach the critical
length, the pipes must be renewed to maintain the stability of the tunneling process.
In this paper, we study the oscillation and nonoscillation theorems
for second order nonlinear difference equations.
By using some important of definitions and main concepts in
oscillation, in addition for lemmas, we introduce examples
illustrating the relevance of the theorems discussed.
The research aimed to study vegetation change detection of Lattakia province by
using remote sensing techniques, By applicating Normalized Differences Vegetation Index
(NDVI) due to what these techniques had from quickly, accuracy, and completely.
In
addition to saving efforts and money. that change detection methods have showed by
applicating it on Sentinel2 images the plant situation, it's area and distribution in the
studied area.
In addition to knowing plant's cover changes through time passing. Putting geo
databases which benefit in knowing plant situation, and the periodicity supervision for it's
changes.
The yearly and monthly changes of vegetation cover have been studied in Lattakia
province, By making change detection for plants cover of march between (2016-2017).
Then making change detection between march and august of 2017. It was observed that
there were no big changes, Whether increasing or decreasing for plants cover when
studying the yearly changes. While there was big decreasing of plants cover at western
plain areas of province when studying the monthly changes between march and august due
to raising of temperatures. And big increasing of vegetation in high areas.
Van Tijm and Victor Gremonsky, in their comparative monetary work, have
established two closely related, largely divergent approaches and research methods. The
first to follow the approach of EvelFeilmann to look at international literary relations
is a
certain historical causation (historical theory). And the second approach to the theory of
typology, influenced by the writings of A. Vesilowski monetary, influenced by German
philosophers, starting in the second half of the eighteenth century. The term similarities
and differences between literatures is presented as a result of similarity or difference in the
movement of the development of societies and their conditions.
However, their divergence in principle did not override their agreement on some
partial issues and their divergence in other matters. This is what the research will try to
look at, using extrapolation as a means to elucidate judgments, which were ignored by
scholars and interested parties, in the hope of giving each person the right, both impartially
and objectively, to adopt their texts.
Deconstruction tries to disrupt the transcendental signification and its domination on
the other implications by introducing a new concept: the concept of free play of the
marque. This concept is based on the philosophy of the otherness and differe
nce. Derrida
never stooped to remind that the difference is not a concept or an idea or a term. We see
the difference as Law, a Law of reading and writing. But it's also the Law of the Other and
the different. It reflectsa philosophy of otherness that is rooted in the writings of Derrida.
Derrida expressed this Law by a formulation that reduces deconstruction as a philosophy
and as a method: tout autre est tout autre, a sentence that says the identity and the
otherness together. It says the identity, and says the other, each other, the other in his
irreducible plurality, the other "is" different and we cannot tell his identity. Peerless
formulation of the Law that says the impossible.
In this
work a computer model based on finite difference method is
developed to calculate the temperatures and thermal
stresses/strains within the roll under various cooling system
parameters for High Chromium Cast Iron Roll, and study of the
effect of each parameter on thermal Fatigue phenomena in this
roll.

In this paper , we will discuss the way of construction of lyapunov
function for some of linear stochastic difference equations
We will use the general method of constructions of lyapunov
function for stochastic difference equations and we will ob

solution for one of linear stochastic difference equations with
constant coefficient ,By using of some main theorems and
definitions for asymptotic mean square stability for linear
stochastic difference equations .
This article addresses the role of space in re-imagining a case of
essentialist society as collective gender paranoia of biological
reconciliation, as presented in Margaret Cavendish‟s The Convent of
Pleasure (1668). Using the institution of the R
oman Catholic
convent, Cavendish‟s play interrogates biological polarity and
disavows establishing reversed gender hierarchies of empowerment
and subservience. To this effect, the play suggests a communal
psychosis, being delusively constructed by antagonistic biological
differences that generate both sexes‟ denial of cyborg or hybridized
dualism in their gender identification. In this regard, the presented
argument addresses several critical lacunae in the scholarship of The
Convent of Pleasure.
Feuerbach tried to make the power of love a kind of power that cannot be matched
with any other power as love defeats all his opponents even if God is one of them. Love is
always victorious. That's what made the concept of love in Feuerbach’s ideas
a
distinguished and unprecedented concept comparing to all concepts handled by those
philosophers before him. This kind of love dominates the body and soul together and it is
inseparable from our body, may not live outside our soul, it is the basis of the body and the
essence of the spirit.
Feuerbach wanted to make love a link between a mankind and another so there is no
love if one existence and the other is absent. Feuerbach doesn’t limit himself at this point
but goes on to ignore the existence of human being without being in love or loved by other
person. That who does not love does not exist, even religion has neither benefit nor
importance if it is not based on love because love is the reason and core in other words
love is the reason behind the existence of religion.
