This research illustrates the design of a parallel plate reflector operating in the visible and near infrared fields, with a reflection and/or transmission coefficients equal to 50%, and robust to the polarization of the used light and its extinction
ratio (PER), in each of the two directions of polarization (perpendicular S and parallel P). Also there is no need for accurate adjustment of the plate so that the angle of incidence is exactly equal to 45.
The research has its various applications in optical measurements laboratories, laser technology laboratories, optical communication laboratories, and photography.
One of the most important applications of this plate is ophthalmology devices, which can be used as glasses for people with impaired vision, light measurements in laser laboratories and optical measurements.
The problem of asylum and enforced displacement has become one of the major challenges defining the features of the 21st Century. The unjust dis-tribution of resources, economic crises, and high levels of unemployment are no longer the primary causes
of the widely spread phenomenon of immigra-tion, rather, it is caused by the noticeable increase of wars, international con-flicts and political crises, as well as their multilateral effects of oppression, poverty, exploitation and insecurity.
The United Nations High Commissioner for Refugees has expressed this reality in a statement made on September 07, 2011, when he said: “We live in difficult times. Political crises are multiplying where we least expect them. Unpredictability became the name of the game.”
The failure of the international community to bring many of the existing conflicts to an end and to avoid the eruption of other ones, has lead the in-stability situation to continue in so many places throughout the world. This has forced hundreds of thousands of individuals to leave their homelands. The figures are striking; by the end of 2017, the number of refugees and asy-lum seekers exceeded 65 million.
With the changed nature of crises, their expanded range and prolonged duration, in addition to the limited available resources and capacities, the failure to meet the increasing needs of refugees and the States’ increasing fears of terrorism, the world community and international organizations started to look for effective tools to improve crisis response systems and use new technologies in a way that ensures the refugees living in dignity and se-curity in countries of asylum instead of approaching them as a burden and a crisis that must be dealt with.
Here appears the role of bio measurements technology as an important tool to respond to refuge crises, including the management of such crises; first, by organizing the life of refugees and granting them ID cards in order to enable them to enjoy their basic rights in countries of asylum and then by changing that to an opportunity for development by working with them to develop their skills and know-how, so that they have access to safe and sus-tainable means of living, especially under the lack of economic and education opportunities and the strict policies applied against them. This must be the case until they manage to return voluntarily to their countries of origin. The human miracle always materializes in post destruction phases. The history proves that investment in human beings is the most effective way to achieve development and reduce the time needed by a country to rise again and that the more a country is destroyed, the bigger is its opportunity for reconstruc-tion.
Based on that and as UNHCR is the agency in charge of organizing the conditions of refugees in countries of asylum and finding durable solutions for them, it registered Syrian refugees in the neighboring countries based on their biometric data. Giving them identities and documenting their events properly is the first step on the long road to solve most of the problems they face both in countries of asylum or when they return home. This includes the problems of documenting personal status events and increases the countries of asylum’s confidence in UNHCR’s systems through confronting the rele-vant challenges and worries, such as faking identities, fraud, counterfeiting, etc. At the same time, these data are hoped to facilitate the return of Syrian refugees to their county when the conditions and circumstances allow such return.
This paper discusses a geothermobarometry modeling computer software called
Thermocalc through an applied example from the southern Syria volcanism, specifically
from Tal Al-Ashaer volcano, is given. A graphical P-T diagram for a given chemical bul
k
composition of some spinel-bearing peridotite rocks (from Tal Al-Ashaer) is created. The
results and their interpretation, in addition to limitations and constraints are discussed.
Based on the mineralogical analysis linked to the studied mineral assemblage modes, the
bulk-rock chemical composition is calculated and a geothermobarometry model using
Thermocalc is made. The created model shows that the general conditions at which the
rock-forming minerals (coexisting in equilibrium) define a field of stability with a range of
temperature goes from 700 to 1100 C° corresponding a range of pressure between 8 and 15
Kbar. Using one of Thermocalc tools (composition isopleths) the most precise P-T
conditions at which the rock was formed are estimated; T = 892 C° and P = 10.5 Kbar. The
corresponding depth at which the studied samples were formed is about 36 Km.
Accordingly, the crust-upper mantle boundary in the studied region is placed at that depth.
many potentially prolific producers have already been plugged and
abandoned , owing to lack of adequate formation evaluation . For
example , In the early days of log analysis، it was common practice
to regard water saturations above 50% as non-com
mercial.
However, with advances in logging and seismic technology came
the realization that some of those supposedly non-commercial zones
were، in fact، highly productive pays , depending on pore-size
distributionof the rock , movable or immovable fluids and
production probability .
Using the petrophysical data and the last structural model,
petrophysical models were built, for ishara east field, one of al
tanak fields in Deiar El Zor. According to the acquired results.
The vertical and horizontal changes of reservoir propert
ies govern
the reservoir assessment in view of storage capability, moreover, it
helps better understanding of the field characterization, also
provides new information to predict these properties in places
which haven’t been explored yet, consequently enhance the
optimization of the reservoir.
Marine sources are of the important sources of coastal States, where a significant
portion of its economy is tied to people who earn their living from these sources [4]. After
the discovery of mineral and hydrocarbons ores at the seabed, and also b
ecause of the
disputes between States on fishing regions, it became necessary for some States to
reconsider their idea regarding maritime boundaries and open the disputed files with
neighboring States even it is over a small area, to demand re-delimitation of their maritime
boundaries, even if it required the intervention of the International Court of Justice. In this
research a way is purposed to draw he coast line by using Google Earth detailed photos for
the derivation of Lattakia coast baseline and studying its various special issues. The search
has found good results in identifying those lines allowing full generalization on the Syrian
coast, and also allowing for subsequent research linked to those lines.
Search includes the geodetic study local network triangulation real estate in Slenfeh
area, and propose a solution for the local network linking public real estate network in
Syria based on a comparison of the 2D-Transformation results so as to cho
ose the optimal
conversion which avoids the occurrence of interactions between regions and schemes real
estate and reduces distortions network after conversion (shift, rotation, scale). At first been
touched to date geodesic network set up in Slenfeh region and the stages of execution, and
the problems of engineering, and then to the transformation methods used in the link, and
apply them to the network, and choose the best conversion, and set parameters optimal
transformation, have been proposed solution depends on the network is divided into three
segments so that Network least deformation resulting from the transformation in each
sector.
A computer program that has been prepared for the implementation of the
transformation and linking local grid points by using the C # programming language.
It has been verified the resultant transformation parameters by comparing linear
measurements calculated from coordinates resulting from the transformation with linear
measurements in the network observation records, and execution field measurements of
some of the points and calculate its coordinates and compare it with the coordinates

A research had been made in three areas at the Syrian Cost where Al Awassi race is
grown; these areas are (Arab Al Mulk, Dwer Al Khateeb, Bekhdarmow). The number of
Al Awassi there reaches to (439) heads. The research was started at 2/11/2009, and
a
random sample of (82)was selected from each area (33-27-22) in a row, and measured
were at the day number (30-90-150) during the season milking, and completed at 4/3/2010.
Results showed at the second phase of day (90) a high measurements of udder which
meets the maximum standards of milk production, and the udder specification had a
significant impact on all forms of the mammary gland (20,01), as well as the nipple
specification, order of milking season, and age had impact on the nipple's size (20,01), but
not on the length of it, but the season milking and age had effect on udder height above the
ground (20,001).
Results showed a correlation which is not fixed between the udder specifications and
quantity of milk as well as a weak and positive relationship between the amount of milk
and nipple measurements in the order of (r=0.33, r=0.49, r=0.19, r=0.27).
