The basis of the film was wheat starch, which tragacanth gum was added at three levels (0.2 and 0.5% by w/w) and clay nanoparticles at three levels (0.1, 0.5 and 3% by w/w). Physicochemical properties of the film, including thickness, water solubility, moisture content, and vapor vapor permeability (WVP), were investigated. The mechanical properties of the films, including the tensile strength and elongation of the films, and the color characteristics of the films were examined. The results showed that adding tragacanth to the starch film increased the thickness, moisture content and permeability of the water vapor and reduced its solubility. The addition of tragacanth to the starch film increased tensile strength and elongation. The addition of tragacanth reduced the transparency of the films. Adding clay nanoparticles to starch film increased the water content, reduced water vapor permeability, and reduced solubility, but adding nanoparticles increased the thickness. Nanoclay increased the tensile strength of the films and reduced the elongation. The lightness of the films decreased with the addition of nano-clay, and the factor b, which indicated the yellowness of the film, increased. In general, it can be concluded that the addition of tragacanth and Nanoclay improves the physical and mechanical properties of starch film.","PeriodicalId":10686,"journal":{"name":"College & Research Libraries","volume":"32 1","pages":"98-103"},"PeriodicalIF":1.8,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87616262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The calculated values of adsorption energy showed the interaction of ampicillin with BN nanocone is experimentally possible. The calculated values of Gibbs free energy and thermodynamic equilibrium constant showed the adsorption process is spontaneous and irreversible. The calculated values of enthalpy changes and specific heat capacity showed ampicillin adsorption is exothermic and BN nanocone can be used for the construction of a new thermal sensor for the detection of ampicillin. The effect of temperature on the thermodynamic parameters was also evaluated and the results indicated ampicillin adsorption is more favorable in room temperature. The NBO results demonstrated in both of the studied configurations a monovalent chemical bond is formed between the nanostructure and the adsorbate and the interaction process is chemisorption. The DOS spectrums showed the bandgap of BN nanocone increased from 1.888 (eV) to 7.030 (eV) which proved this nanomaterial is an appropriate electrochemical sensing material for detection of ampicillin. Some important structural parameters such as dipole moment, electrophilicity, maximum charge capacity, chemical hardness and chemical potential were also calculated and discussed in detail.","PeriodicalId":10686,"journal":{"name":"College & Research Libraries","volume":"124 1","pages":"110-116"},"PeriodicalIF":1.8,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82646419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of agents that are able to inhibit the dengue virus (DNV) replication are therefore of utmost significance. I. tinctoria is one of the most investigated Chinese herbs, which has been recognised to be effective in the treatment of dengue fever. However, the mechanisms through which it exhibits such biological activity of great importance are still unclear. A total number of about 27 compounds isolated from I. tinctoria leaves which have been identified and reported in the literature to be effective against dengue fever were investigated for their inhibitory potencies against dengue virus as novel drugs for treating early attacks of dengue fever. The compounds were optimized by employing a method of Density functional theory (DFT) and a basis set of B3LYP (6-31G**). The results of Molecular docking investigation between the compounds and the dengue viral protein (PDB: 6MO1) revealed that three of the compounds (GB-20, GB-19, and GB-6) possessing best binding energy in of -27.051, -26.193 and -24.664 kcal/mol respective were observed to inhibit the target through hydrogen bonds and hydrophobic interactions with amino acids residue of the protease binding site. The results of these studies would offer relevant insight into structural requirements for the development of effective and a specific therapeutic treatment against dengue virus infection.","PeriodicalId":10686,"journal":{"name":"College & Research Libraries","volume":"116 1","pages":"104-109"},"PeriodicalIF":1.8,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74759286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the use of chemical insecticides, effects of ZnO nanoparticles, Kaolin alone or in pairwise combination with NeemAzal-T/S against egg and second instar nymph of B. tabaci and pupae of its parasitoid Eretmocerus mundus Mercet were evaluated. The LC50 values of ZnO NPs, Kaolin and NeemAzal-T/S against eggs and nymphs of B. tabaci were 7.49 mg L-1, 24.89 g L-1, 6.83 mg L-1 AZA and 6.93 mg L-1, 18.36 g L-1 and 6.00 mg L-1 AZA 3 days after treatment, respectively. The LC50 values of ZnO NPs, Kaolin and NeemAzal-T/S against E. mundus were 11.30 mg L-1, 41.59 g L-1, 36.90 mg L-1 AZA, respectively 3 days after treatment. In the laboratory conditions, ZnO + NeemAzal and Kaolin + NeemAzal exerted a higher level of control on eggs and nymphs of the pest than either alone, while they had a lower level of negative effects on the parasitoid pupae, too. In the field conditions and at 7 DAT, Kaolin + NeemAzal was the most effective treatment on eggs of the pest, causing a 67.43% reduction, while NeemAzal-T/S was the most effective treatment on nymph (86.52% reduction), which was not different with ZnO + NeemAzal and Kaolin + NeemAzal. NeemAzal and ZnO exerted the highest and lowest mortality on pupae of the parasitoid, respectively. Based on the field studies, ZnO NPs at 20 mg L-1, Kaolin at 30 g L-1, NeemAzal-T/S at 15 mg L-1 AZA and mixing equal volumes of NeemAzal-T/S (7.5 mg L-1 AZA)+ZnO NPs (10 mg L-1) and NeemAzal-T/S (7.5 mg L-1 AZA)+ Kaolin (15 g L-1) can be suitable candidates in IPM programs of B. tabaci field condition.","PeriodicalId":10686,"journal":{"name":"College & Research Libraries","volume":"85 1","pages":"131-139"},"PeriodicalIF":1.8,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76724723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
