يظهر البحث أهمية حساب و معرفة زاوية الحقل المغناطيسي الأولي لمحطة المرسل باستخدام طريقة التردد المنخفض جداً و أهميته في القياسات الحقلية الكهرطيسية عن طريق معرفة إحداثيات كل من محطات الإرسال العالمية لهذه الطريقة و إحداثيات منطقة القياس باستخدام معادلات خاصة بذلك. حسبت زوايا سمت الحقول المغناطيسية لهذه المحطات في بعض المناطق السورية في درعا و السويداء, و تبين أن هذه الزوايا تتغير في الموقع نفسه بتغير إحداثيات المرسل, و نُفذّت قياسات حقلية أكدت ذلك.
The work demonstrates the importance of calculation of zenith angel of the primer magnetic field of the transmitter-station through knowledge of the coordinates of both transmitter-station and measure- area due to the use of special equations. They have great importance for electromagnetically field measurements. The direction angels have been calculated for most famous transmitter-stations in some different areas of SYRIA (DRAA and SUWEDA). According to the results, these angels differed with the variation of coordinates of the transmitter in the same location, and some field measurements have confirmed this method.

The Shared Task on Evaluating Accuracy focused on techniques (both manual and automatic) for evaluating the factual accuracy of texts produced by neural NLG systems, in a sports-reporting domain. Four teams submitted evaluation techniques for this ta
sk, using very different approaches and techniques. The best-performing submissions did encouragingly well at this difficult task. However, all automatic submissions struggled to detect factual errors which are semantically or pragmatically complex (for example, based on incorrect computation or inference).
Several studies have been carried out on revealing linguistic features captured by BERT. This is usually achieved by training a diagnostic classifier on the representations obtained from different layers of BERT. The subsequent classification accurac
y is then interpreted as the ability of the model in encoding the corresponding linguistic property. Despite providing insights, these studies have left out the potential role of token representations. In this paper, we provide a more in-depth analysis on the representation space of BERT in search for distinct and meaningful subspaces that can explain the reasons behind these probing results. Based on a set of probing tasks and with the help of attribution methods we show that BERT tends to encode meaningful knowledge in specific token representations (which are often ignored in standard classification setups), allowing the model to detect syntactic and semantic abnormalities, and to distinctively separate grammatical number and tense subspaces.
The study aimedat identifying the role of farmers field school ( FFSs) in Jablah, and
the characteristics of their participant, their opinions, their productivity, and the difficulties
they suffer from.
To achieve the objective of this study , dat
a was collected through random sample ,
its size is (75) participant farmers in five field schools,by questionnaireby the personal
interview method , the process of data collection was started in 15/5/2013 and completed
in 15/8/2013.
The results showed that 92 % of farmers wish to continue in FFSs, and all of them
indicated that the more activities of (FFSs) is to analyze the ecosystem,and 43,5%of them
refer that the suitable location is the most important conditions essential to choose the
field of experience .
The productivity of citrus participantfarmers in the field schools is more than 5 tons
/acres ( 59,3% ), and The productivity of tomato farmersranging between 8 - 12 tons /acres
( 76,6% ).
Our study included (84) patients: 86 cases suffering from chronic osteomyelitis: various causes, location and degrees.
All patients operated: after curettage of necrotic and infected tissues; system of continuous irrigation with antibiotics was in
serted to the infected zone; all cases were followed up for 1 year. 86% of positive results were obtained and results were bad in 14% of cases>
The high positive results (86%) confirm high effect of continuous irrigation with antibiotics as a good method for chronic osteomyelitis treatment, because this method allows delivery of suitable antibiotics in high concentration into the infected area, which is enough to kill microbes and allows to obtain best results.
Research offers expanded version of the relationship to improve measurement
accuracy (provided by Otrenbski), which include correlated or free geodetic networks, with
correlated or incorrelated observations, which are processed according to the Lea
st Square
theory. In addition to enhancing the Global accuracy, Research gives additional formula
takes into consideration the enhancement of each observation (local precision). the validity
of the proposed formula was proved depending on the Idempotent matrix.
In addition to the general concept of the reliability of geodetic network (described in
literature), Research gives the formula of the relationship between improvement of
measurement accuracy and one of internal reliability features (provided by Pelzer), and
used in the evaluation of geodetic measurements. Research find and gives the basic
mathematical indicators of the interaction of processing model with the occurrence of
errors in geodetic measurements.
