أجريت هذه الدراسة عام 2013 في موقعي كسب و الربوة التابعين لمحافظة اللاذقية حيث نفذت جولات حقلية بهدف حصر و توصيف الطرز المحلية للتفاح المنتشرة في هذين الموقعين. تم من خلالها تحديد خمسة طرز محلية للتفاح هي: بربوري و سكري و شرخوشي و ملكي و جبق جيان، و بنتيجة تحليل التباين عند المستوى /5%/ للصفات الظاهرية المدروسة و البالغة (17) صفة للورقة و الزهرة و الثمرة و البذرة . أظهرت هذه الطرز اختلافات شكلية واضحة فيما بينها ، إضافة إلى اختلافات معنوية من حيث محتواها من السكريات الكلية و الحموضة الكلية و نسبة المواد الصلبة الذائبة الكلية و نسبة فيتامين C، و من خلال حساب درجة التشابه ما بين هذه الطرز فقد وجدت أعلى درجة تشابه بين الطرازين شرخوشي و جبق جيان (41.17)%، و أقلها بين ملكي و سكري و بين سكري و جبق جيان(5.88)%.
This study was conducted in 2013 in Kassab and Alraboa locations that is located in the province of Latakia, where carried out with the aim of rounds field inventory and characterization of types of local apples deployed in this locations. Was to determine which of five local types for apples are: Brobory and Sokary and Cherkhoshy and Malaky and JbakJian, and the outcome of the analysis of variance at the level / 5% / virtual studied for recipes of (17) characters for the leaves, blossoms, fruit and seed. These types showed clear differences formality between each other, in addition to the significant differences in terms of the content of total sugar, acidity, total soluble solids and the percentage of vitamin C, by calculating the degree of similarity between these types have found a higher degree of similarity was between the types Cherkhoshy and Jbak Jian(41.17)% , and the least was between Malaky and Sokary and between Sokary and Jbak Jian(5.88)% .

From statistical to neural models, a wide variety of topic modelling algorithms have been proposed in the literature. However, because of the diversity of datasets and metrics, there have not been many efforts to systematically compare their performa
nce on the same benchmarks and under the same conditions. In this paper, we present a selection of 9 topic modelling techniques from the state of the art reflecting a diversity of approaches to the task, an overview of the different metrics used to compare their performance, and the challenges of conducting such a comparison. We empirically evaluate the performance of these models on different settings reflecting a variety of real-life conditions in terms of dataset size, number of topics, and distribution of topics, following identical preprocessing and evaluation processes. Using both metrics that rely on the intrinsic characteristics of the dataset (different coherence metrics), as well as external knowledge (word embeddings and ground-truth topic labels), our experiments reveal several shortcomings regarding the common practices in topic models evaluation.
The aimsof this research were to morphologically characterize 27 local genotypes of
tulip,to evaluate the genetic variability between them using 32 morphological traits, and to
determine their chromosomal number.
The results allowed the distinctio
n between the studied genotypes based on the
morphological characterization of all vegetative,floral andbulb traits. Results confirmed
that the main limiting factor for distribution over the screened regionwas the high above
sea level.All genotypes were divided into two main groups, the firstone included genotypes
located at 400 - 850 m of altitude, and the second one located between 950 -1450 m.
The microscopic analysis results showed that all the studied genotypes were diploid
(2n=2x=24 chromosomes).
Depending on the results of the morphological characterization and the chromosomal
number of local genotypes studied, it can be considered the closest to the specie
Tulipaagenensis D.C.
The study was conducted in four sites belonging to the Sheikh Badr district in Tartous
province. Ten different types were identified according to international standards. During
the 2016 and 2017 growth seasons, readings were recorded for phenotypi
c parameters as
well as physical and chemical analysis of fruit clusters. The studied types differed in many
characteristics. The results of the cluster analysis showed the distribution of the studied
types in two groups with a variance of 93%. The mean weight of the cluster varied
between the medium (349 g) and the large (1140.45 g). The ratio of total dissolved solids
(TSS) between the low (12.75%) and high (18.82%). the acidity between the very low
(3.53 g/l) and medium (6.38 g/l).
The response of barley variety Furat9 (tow-rowed), has been noted for three doses of
Gamma radiation (10, 15, and 20 Kr). The objective of the research, to evaluate and
characterize the quantitative and qualitative traits, to identify and calculate
the proportion
of the total and relative changes, to determine the best doses of Gamma rays, and to study
the relationship among the traits in the second generation.
