Fiber reinforced polymer (FRP) plates have gained popularity in the strengthening of reinforced concrete (RC) members due to the high strength to weight ratio, the ease of installation and low maintenance costs compared to other systems such as steel
plates. Also, external bonding of fiber reinforced polymer (FRP) plate has been proven to be an effective method to strengthen and damage RC structures. However, not much attention has been given to the long-term behavioral aspects of FRP-strengthened RC members. It is difficult to accurately predict the long-term deflection, crack width and behavior of FRP-strengthened RC members.
This study presents a method for predicting the deflections at any time of the service life of normal and high strength concrete structures, loaded at any age, creep coefficient and shrinkage strain and the participation of the compressive steel for RC beams, and for RC beams strengthened with FRP plates.
The accurate prediction of deflections is a complex problem which requires the use of non-linear and time-dependent analytical methods. These methods are, in general, time consuming and require great effort[6-13]. However, at the design stage, simple but reliable methods which take into account the most important parameters influencing the long-term deflections may be very useful to adequately design the structure. For that purpose, many simplified methods have been developed [1-2-3-4-14]. Equations have been programmed to access the method combines the simplicity and accuracy and provides valuable information about the influence of each parameter on the increasing deflections with time.
The analytical values are compared to the experimental results from some existing papers [8-9], and to the results obtained from ACI code [1]. It is found that the analytical method is in a good agreement with the experimental results from some existing papers
[8-9].
This research studies the linguistic theory throughout Arabic Language characteristics and laws which could be Found in structure of language. It also draws attention to the constituents of the mental existence, and connects them with the linguistic
deduction. This study discusses the linguistic phenomena, and analyzes the linguistic structure in the same way wherefrom we can see the language as sensual existence phenomenon overlapping with abstract lawsof thebehavior of things.Subsequently, this study tries to confirm the relevance, on theone hand, between the language as a human phenomenon and the mental laws. On the other hand, it relates to the language and the material laws bringing out the beauty of the Arabic language.
Recently laser applications have been expanding to include many fields.
Among these, are medical laser surgery and biological applications. It is
important to understand the interaction mechanisms that may occur when
applying laser light to biolog
ical tissues in order to minimize damage to the
tissues resulting from extra heat applied. The aim of this study is to study the
temperature distribution in living biological tissues when laser irradiation is
used in a treatment by solving bio-heat equation.
This research deals with time psychology in stories of the Holy Quran. It begins with
defining time psychology and shows its kinds and their reasons, from a personal and
internal time and the time of ego. Then the research moves on to reveal the ti
me
psychology in Arabic Literature and it begins with poetry. It displays some lines of verse
that illustrate the sense of time, and then it clarifies the meaning of time psychology in the
new narrative studies.
After that, the research deals with time psychology in the story of the Holy Quran
and the wrong estimate of time due to not realizing it because of the loss of loss of life, or
unconsciousness. Then it exposes some human moments of different characters from the
Holy Quran, like incidents of drowning, giving birth, moments of fear and worry, moments
of departure and meeting and the moments of determining and triumph.
The research demonstrates that the story in the Holy Quran can transmit human
feelings, explain emotions and express psychological senses and the inner depths of the
characters, using words with high level of transparency and subtlety. The words are
meaningul and carefully chosen.
So, all of that what has probably given the miraculous story of the Holy Quran it's
superiority in both it's linguistics and semantics. Also, it exceeds high above the limited
level of the human capacity.
This research is about verb tenses according to ancient and modern linguists. Verb
refers to actions and tenses. They have grammatical tenses which are related to
formula and morphological tenses which depend on context.

This research deals with the role of the context in the rotation between the actual
forms of past, present and future, time is often divided into past, present and future
formulas, the research examines the contexts that leads the original time fro
m its position
to another time that does not indicate it in the first place that shows that there is a
difference between the temporal time and the grammatical, the research shows that the
formula of the present verb is different from that of the past because of the existence of a
presumption function and repent formula of the past about the present and future, which
does not indicate by the origin of the past but the present time and future, so the context
determines the grammar time.
Assabihas the ability to form his story in a narrative strong
style . He passes his thought through it as if you see it in front
of your eyes. This returns to the connection between its
narrative components that he well organized its structure .He
makes every component of them : Personality, Time, Place ,
Incident and a narrator that are doing his private role . The
time appears to him with the figure that helps the incident to
express the components of the story using the different time
techniques of: Summary, omitting , retrieve , raise and
caesura/ pause through description .So this component appears
to be a useful instrument between the hands of a professional
writer.
