تعد تقانة الأضداد النانوية من طرائق البيولوجيا الجزيئية الواعدة، التي تجري من خلال الهندسة الوراثية لنوع خاص من الأضداد ذات السلاسل الثقيلة فقط التي تتميز بها عائلة الجمال Camelidea, بحيث تُمكن من الحصول على بروتينات صغيرة الحجم تُدعى بالأضداد النانوية التي تمتاز بكونها عالية الثباتية و الانحلالية و قادرة على الارتباط بمستضدها النوعي. تُنسل مورثات الأضداد النانوية خلال مراحل إنتاجها ضمن بلاسميدات أنظمة التعبير البروتيني مما يسمح بإنتاجها بصورة مستمرة و ثابتة لاستخدامها في أهداف بحثية و تطبيقية.
Nanobody technology is considered as a promising molecular biology technique performed by means of the genetic engineering of special type of antibodies, existing exclusively in Camelidea. It enables the obtaining of small proteins, referred to as Nanobodies, which are characterized by high stability and solubility, are able to link to their specific antigens. After production, the Nanobody genes are cloned within plasmids of protein expression in bacteria, allowing their stable and continuous production for research and applied purposes.

The following Fungal species were isolated from therhizosphere of wheat plant (TriticumaestivumL.): Trichodermaharzianum, T. viride, T. longibrachiatum, Rhizoctoniasolani, Alternariaalternata, Fusariumsolani, Fusariumoxysporum and Aspergillusniger. I
t was shown that all isolated fungi had the capacity to produce cellulase in solid medium (CMC- Agar), while the fungus T.viride gave the highest capability for the production of this enzyme(5.16). The fungus Rhizoctoniasolani gave less productive ratio (2.61). Quantitative test using Mandelium liquid medium showed that the fungus T.viride had the highest productivity of Cellulase(4.39 U/mL), and this fungus had greater biomass (8.96 g/L). The fungus Rhizoctoniasolani gave lower enzyme productivity(2.04 U/mL) and its biomass reached(4.65 g/L). The study of different carbon sources for the fungus T.harzianum showed that Sucrose was the best media in Cellulase productivity. It reached (3.87U/mL), and the biomass was (2.83 g/L).
Fifty eight isolates of lactic acid bacteria were obtained from different
local fermented foods. Isolates were identified using microscopic, cultural and
biochemical tests using API strips. Results showed that 44.83% of the isolates
were rod shape
d and 55.17% belonged to cocci bacteria.
Monodispersed CdSe nanoparticles with sufficient luminescence intensity have been prepared by chemical method in solution phase, and in two forms: CdSe as a core covered by Olic acide as an organic capping agent, while the second form is CdSe as a co
re covered by a layer of CdS (CdSe/CdS core shell). The nanodots size obtained directly from high resolution transmission electron microscopy (TEM) and absorption peaks using Paul Mulvaneys formula are in good agreement. The optical properties and the luminescence intensity as a function of CdSe concentration and the type of solvent have been investigated. The intensity of photoluminescence peak decreases and the peak shifts toward the blue energy side as the concentration reduced
A Lie algebra g over a field F is a vector space together with a bilinear
map [ , ] satisfying [x ,x ] = 0 in addition to Jacobi identity . A Lie subalgebra
B of a Lie algebra g is said to be a Cartan subalgebra if it is a nilpotent and
equals its
normalizer, and it is proved that semi simple Lie algebra g
decomposes into weight spaces for B.
In this scientific paper we present the conception of distinguished
element 0 h in finite dimensional semi simple Lie algebra over a field F has
characteristic 0 and we will prove that the previous decomposition g into
weight spaces for B is the same to decomposition g as a direct sum of h0 ad eigen
spaces. This leads us to construct algorithm to test simple Lie algebras.
We programmed the previous algorithm to test simple linear Lie algebras
over a numeral field by Mathematica 5.0 program where applied this algorithm
on semi simple linear Lie algebra SL(3, ) to prove that it is simple.
The task of Event Detection (ED) in Information Extraction aims to recognize and classify trigger words of events in text. The recent progress has featured advanced transformer-based language models (e.g., BERT) as a critical component in state-of-th
e-art models for ED. However, the length limit for input texts is a barrier for such ED models as they cannot encode long-range document-level context that has been shown to be beneficial for ED. To address this issue, we propose a novel method to model document-level context for ED that dynamically selects relevant sentences in the document for the event prediction of the target sentence. The target sentence will be then augmented with the selected sentences and consumed entirely by transformer-based language models for improved representation learning for ED. To this end, the REINFORCE algorithm is employed to train the relevant sentence selection for ED. Several information types are then introduced to form the reward function for the training process, including ED performance, sentence similarity, and discourse relations. Our extensive experiments on multiple benchmark datasets reveal the effectiveness of the proposed model, leading to new state-of-the-art performance.
