تم دراسة تأثير مصادر تباين تصميم المربع اللاتيني السحري في تخفيض قيمة الخطأ التجريبي، في تجارب الأحياء الدقيقة (بكتريا حمض اللبن) و اثبات فاعلية المستطيلات العشوائية كأحد مصادر تباين المربع اللاتيني السحري، حيث تم إجراء توزيع عشوائي ل ( 6 ) معاملات مفترضة على ( 36 ) وحدة تجريبية و قد كررت عملية التوزيع ( 150 ) مرة بهدف الحصول على مربعات لاتينية سحرية تتحقق فيها الشروط التي تظهر فيها المعاملة الواحدة مرة واحدة في السطر و العمود، و المستطيل ضمن التصميم الواحد.
This research was conducted to study the effectiveness of the variations of magic latin square design, to reduce the value of the experimental error, in experiences of microbiological (Lactobacillus acidophilus), and to improve the activity of random rectangles as one source of the variations of magic latin square design. Where they were conducting a random distribution of (6) treatments supposed to (36) experimental unit test has repeated the process of distribution (150) times in order to obtain magic latin squares realized the conditions which show per treatments once in the row and once in the column, and once in each rectangle within the one design.

Abstract:
This research was conducted to study the effectiveness of the
magic latin square design, to reduce the value of the
experimental error, compared with the traditional latin square
design experiences of microbiological (Lactobacillus
acidophilus ) by using the Cochran test ( Gmax ).
In this study, microorganism separated from the Syrian soil were used in
treating the waste water from dyehouse and some dyes which are oftenly
applied. A great difference was found in the speed of microorganism growth as
well as the great variati
on in color disappearance, in addition to inactivating
the enzymatic work by some of the dyes. Also, the effect of the dyes density on
the growth of microorganism. The absorption strength measurment in the field
of visible spectrum between ٣٥٠ –٧٥٠ nanometers was adopted for analyzing
the filtrates resulting from the biological treatment .
In the sixth edition of the WMT Biomedical Task, we addressed a total of eight language pairs, namely English/German, English/French, English/Spanish, English/Portuguese, English/Chinese, English/Russian, English/Italian, and English/Basque. Further,
our tests were composed of three types of textual test sets. New to this year, we released a test set of summaries of animal experiments, in addition to the test sets of scientific abstracts and terminologies. We received a total of 107 submissions from 15 teams from 6 countries.
Identifying intertextual relationships between authors is of central importance to the study of literature. We report an empirical analysis of intertextuality in classical Latin literature using word embedding models. To enable quantitative evaluatio
n of intertextual search methods, we curate a new dataset of 945 known parallels drawn from traditional scholarship on Latin epic poetry. We train an optimized word2vec model on a large corpus of lemmatized Latin, which achieves state-of-the-art performance for synonym detection and outperforms a widely used lexical method for intertextual search. We then demonstrate that training embeddings on very small corpora can capture salient aspects of literary style and apply this approach to replicate a previous intertextual study of the Roman historian Livy, which relied on hand-crafted stylometric features. Our results advance the development of core computational resources for a major premodern language and highlight a productive avenue for cross-disciplinary collaboration between the study of literature and NLP.
This research deals with the minimum cost design of reinforced concrete T-beams
according to the Syrian code. The aim is to minimize the total cost of the beam while
respecting all the design requirements. Traditional method depend on a set of supp
ositions,
in the opposite this methodology aim to reach the optimal solution among a set of
constraints with respect the objective function. So that, using this methodology leading to
the minimum cost reinforced section design.
This research is shown that the problem can be formulated in a nonlinear
mathematical programming format.
Several cases are used to explain the applicability of the formulation in accordance
with the current Syrian code. Traditional method of Syrian code has been used to design
sections in this paper, utilizing the nonlinear programming method provided by Lingo14.0
software from LINDO Systems Inc. The comparison of the results shows that important
saving can be obtained at the total cost of a reinforced concrete T-beams design.
