Vanillin was used as renewable resource for preparing new monomer in two stops. The monomer has tertiary amine group which facilitates the pH change and functional aldehyde group that encourages the formation of Schiff base. It was abbreviated by DEAMVA and evaluated using chemical analysis e.g. 1H NMR, 13C NMR and FT IR all data were in logic case. Copolymerization of Styrene with 5 and 15 mol% of DEAMVA has been done by free radical polymerization and AIBN as initiator. The copolymers have been chemically and physically characterized e.g. 1H NMR, FT IR, GPC, and DSC. Post polymerization of poly (styrene-Co-DEAMVA) with 15 mol% (III b) was prepared for immobilization of tryptophan and investigated by the same methods used lately. Moreover, the sensitivity of the posted copolymer to pH has also studied by UV-vis. Spectroscopy. Scanning electron microscopy (SEM) was used to study the morphological feature of polymer surface after immobilization of tryptophan.

In a previous study we focused on the synthesis of new family of unsaturated copolyesters and terpolyesters by interfacial condensation polymerization. Here, in this study as complementary work of physical characterizations, we focused on the morphological features using X-ray and SEM investigation. Further, the mechanical properties of solid polymers were also studied by a new technique echo-pulse using ultrasonic impulses. This technique was used for solid polymers to determine the elastic moduli involving, Young’s modulus, shear modulus, bulk modulus and micro-hardness modulus. The statistical relation between different kinds of copolyesters and terpolyesters with Poisson’s ratio (υ) and micro-hardness were shown. The dielectric constant (?) and the electrical resistance (Rp) of the solid copolyesters and terpolyesters including aliphatic, aromatic and azo group in the main chain have been studied at room temperature. Moreover, the relation between frequency and dielectric constant for the selective polymers has been also illustrated.

This article reports on the synthesis of acrylate monomer from renewable material. Vanillin was selected to be the start material to produce new monomer called vanillin acrylate and abbreviated by (VA). It has been successfully investigated by 1H, 13C NMR, IR and UV and all results were in logic state. The next step was to synthetize three different thermo-responsive functional copolymers by incorporation of three different molar ratios of vanillin acrylate (10, 20, 30 mol%) with N-Isopropylacrylamide via free radical polymerization by AIBN as initiator in solution. All copolymers were deduced by 1NMR and IR and all showed the presence of aldehyde group. The copolymer was used for grafting of tryptophan and β-alanine through the chemical link between amino group and the active aldehyde group by click reactions to form Schiff’s base imine compounds. Moreover, polymers were also elucidated by 1HNMR, IR and UV, Size Exclusion Chromatography (SEC) was used for the molecular weight determination, differential scanning calorimeter (DSC) for glass temperature of solid polymers, XRD for crystallinity. UV-vis Spectroscopy was used for the determination of phase separation or the lower critical solution temperature (Tc) of polymers solution not only in deionized water but in pH5 and pH11. The mount of conversation and linked amino acid was determined by UV-vis Spectroscopy.

目前,由于各种常见和罕见疾病的增加,大多数人尤其是老年人,如果同时服用两种或两种以上的药物,这些药物可能会导致严重的健康问题甚至有致命的副作用。这被称为药物相互作用(Drug-Drug interaction,DDI),可能会导致药物不良反应(Adverse Drug Reaction,ADR)。对于患者、医务人员和医疗保健管理来说,DDI提取和检测是一个极其重要的研究领域。因此,专家们开始在数据集中对药物信息进行分组,以方便的提取不同的药物和其他化学物质、作用和关系。目前针对该事件已提出的自然语言处理方法,如使用文本挖掘工具改进医学文本中的DDI提取。由于早期基于规则的机器学习和深度学习方法的效果表现不太好,学者们尝试使用名为BERT和BioBERT的预训练模型来提升实验效果。本文提出了一种基于BioBERT的高效DDI提取模型。此外,本文提出了两种不同的方法来从医学文本中提取药物名称:一种是使用BERT,另一种是使用spaCy库。论文的第一部分重点介绍了DDI的第一个任务,即药物命名实体识别(Drug Named Entity Recognition,DNER)。在这个任务中,首先,本文提出了一种使用spaCy的DNER方法。该模型在召回率和f-score方面取得了78.69%和79.81%的结果。之后,本文提出了基于BERT预训练模型的方法,并取得了较高的召回率、准确率和f-score。实验结果表明,基于BERT的方法在召回率和f-score方面分别达到了87.3%和87.9%,优于其他方法。通过对两种DNER模型的实验结果进行对比,发现基于BERT的模型在准确性、召回率和f-score方面优于基于spaCy的模型。在论文的第二部分,本文提出了一个基于BioBERT的DDI提取模型。该DDI提取模型由两部分组成,第一部分使用BioBERT进行文本的关系分类,第二部分使用变分自编码器解决药物的化学结构表示问题。在对基于BioBERT的DDI模型的分析过程中,本文还研究了增强化学结构信息带来的性能提升。实验结果表明,基于“biobert-v.1 pub Med”的DDI模型在基于文本的关系分类上取得了最佳效果。最终,本文提出的DDI模型取得了90.92%的准确率和82.23%的F-score,在F-Score上超过基于CNN的模型12.48%,超过基于LSTM的模型12.84%,超过基于RNN的模型8.73%。

The research was elaborated in Kafr El-Dawar area (Egypt northern region) to study the availability of the soil plant nutrients. The research introduced three parameters to comprehensively and carefully describe the availability of the soil plant nutrients: potentiality, gradient and anisotropy. Potentiality defines the categories of soil ability to supply plant nutrients;meanwhile gradient expresses the increasing rate of the availability of the soil plant nutrients. The gradient anisotropy refers to the directions or orientation of the increasing rate of the availability of the soil plant nutrients. The introduced parameters enabled to spatially study the availability of the soil plant nutrients. Analytical data, of soil available phosphorus (P), indicated that P ranged from 0.2 ppm to 11.4 ppm to locate all studied soil samples into the low class of the soil nutritional P ability. This was not the case of available potassium (K), where the soil samples were distributed into three available K soil categories: medium, high, and very high. GIS map of soil P nutritional potentiality for plant (potato), displayed the soil studied area in one category, as low P soil nutritional potentiality to coincide with the analytical data classification. Contrary, the K map classified the soil studied area into three categories of soil K nutritional potentiality: medium, high and excessive. This obviously referred that the individual determination of soil K nutritional potentiality is misleading for interpretation of soil tests because it does care of the spatial distribution of soil available K. Nearly, all soil samples had high available micronutrients that they were located in the high category in both classification of analytical data and GIS maps. GIS gradient maps of the soil available plant nutrients referred that the soil plant nutrients, exception of K, had two gradients: non increasing-slight increasing and build up. Gradient of soil available potassium was classified in
