Influence of Different Non-color Background on Tourmaline Green
Authors: Jia Haoyuan , Guo Ying , Li Yinuo , Yuan Bin 
Published: August 2019

Abstract
On the basis of uniform color space CIE 1976 L*a*b*, using Munsell color system as a contrast system, this paper discusses the influence of different achromatic backgrounds on tourmaline green through quantitative analysis of color indexes such as lightness, chroma and hue of green tourmaline, and draws the following conclusion: in the process of achromatic background lightness transformation, the lightness and chroma of green tourmaline are highly sensitive to it and have obvious changes along with it, and the two also have high synchronization; However, the hue has not changed much. At the same time, the green tourmaline itself has higher lightness and chroma, which can make the lightness of the achromatic background more effectively converted into the visual lightness and saturation of the tourmaline, but the green tourmaline with too high or too low lightness and chroma is hardly affected by the lightness of the achromatic background. This proves that the non-color background is suitable for most tourmaline green quality evaluation.
Effect of Nano-montmorillonite on Properties of Spray-dried Cinnamon Oil Microcapsules
Authors: Wang Hui , Yang Bo , Bai Yan 
Published: August 2019

Abstract
Proper dispersion of layered nano-clay within the wall of oil microcapsule is a strategy for improving encapsulation properties. In the present study, cinnamon oil microcapsules with addition of nano montmorillonite (MMT) in wall materials were prepared by spray drying, encapsulation efficiency (EE) and loading capacity (LC) were measured. The release properties of microcapsules at different humidity and high temperature were investigated. The results show that the emulsion with 12% MMT content has the highest stability and shows the lowest droplet mean diameter. The EE and LC increase with the increase of MMT content and reach the maximum at 12% MMT content as a function of compact wall membrane structure formed from MMT dispersed in polymer. The addition of MMT decreases cinnamon oil release rate and improves the barrier property of wall membranes due to the less water absorption. Thermal stability of microcapsules is also enhanced.

Published: August 2019

Abstract
The PZT multilayer films were prepared by sol-gel method. The effects of formamide content, crystallization temperature and number of layers on the microstructure and ferroelectric properties of PZT films were investigated by optical microscopy, XRD, AFM and SEM. When the content of formamide in the PZT precursor solution is 0.34% by weight, the surface morphology is flat, and the film formation and crystallization are highest when the crystallization temperature is 690 °C. The surface of the four-layer film has low undulation, less impurities, and uniform particle size and particle distribution on the surface of the film. The maximum undulation of the film is 10 nm, the average undulation is 6 nm, and the ferroelectric domain is dominated by 20° domain and 200° domain. When the polarization inversion voltage is 8.0V, the loaded pattern is polarized and flipped, and the flip angle is about 180°. The inverted ferroelectric domain is very stable.

Published: August 2019

Abstract
Gas phase diffusion process of UDMH and NTO in confined space was investigated and the mechanism of the reaction between the propellants was analyzed in order to study the diffusion process considering chemical reaction between propellants based on numerical simulation. According to the results of numerical simulation, the propellant concentration distribution, resultant of reaction distribution, as well as temperature distribution was obtained. Results showed that the leakage diffusion process can be divided into three stages: heavy gas deposition stage, rapid reaction stage and equilibrium diffusion stage. In the heavy gas deposition stage, propellants are mainly affected by gravity. During the rapid reaction stage, the chemical reaction between propellants plays a certain role in the diffusion process. In the equilibrium diffusion stage, the bottom temperature of the confined space increased significantly, the highest temperature reached 306K.

Published: August 2019

Abstract
Computer vision systems are a very interesting alternative approach for the forest species classification, which is a challenging task that generally requires well-trained human specialists. Hence this work proposed a method concerned with computer vision system to classify 37 different forest softwood species. The images are being decomposed to red, green and blue channels to extract features, each channel is decomposed using a different discrete wavelet transform (DWT) family. The image features are prepared to be classified. Texture images of softwood species are classified using neural network (NN) and support vector machine (SVM) classifiers. Classification accuracy (CA) values for SVM were 94.7297% and 97.2973% for 3rd and 5th level decompositions “coif2” DWT respectively which are better than NN results.

AbstractThe study has been conducted in the laboratory of Imam Hussein Center (peace be upon him) for the restoration and conservation of manuscripts and the care of researchers at the Imam Hussein Holy Shrine. 150 fungal isolates of Aspergillus spp. have been taken from manuscripts. Aspergillus, Aspergillus flavus, Aspergillus nidulans, Candidus,Apergillus oryzae, Apergillus niger were diagnosed. The enzymatic tests were performed to determine which species has the ability to produce analyzer of protein,cellulose, fat and starch enzymes on solid culture media of specific inspection.The results showed that Aspergillus fungi were differentiated in its production of the studied enzymes. A. nigar gave positive result for all studied enzymes with varying level of efficacy. The highest enzyme activity of this species was amylase, lipase and cellulase. However, A.oryza recorded the highest efficacy of cellulase and amylase and medium efficacy with protease. A. candidus was producing high efficacy to protease, lipase and cellulase enzymes and gave a negative test with the amylase enzyme. A.flavus was the higher efficacy with protease, lipase, cellulase enzymes and medium efficacy with amylase, while A. nidulan was recorded as the highest efficacy with protease, lipase, and cellulase enzymes and medium efficacy with amylase enzyme.The effect of growth of these fungi on the physical properties of the elongation strength, tension force and color change of paper was studied. The results showed that the effect of fungi on the manuscripts through the exposure of the damaged sample to the dark color compared to the standard sample (unaffected). The results demonstrated that the lowest values in term of tensile strength and elongation for the affected sample compared to the non-affected sample, as well as the study of their effect on the chemical properties using X-ray diffraction analysis to determine the degree of crystallization of cellulose. The results showed an increase in the crystallization of cellulose. This means a change in the chemical and mechanical properties of cellulose. In addition, the infrared spectrum was used to determine changes in the functional groups of paper observing which revealed occurring a slight decrease in the OH group as a result of the loss of water molecules from cellulose. Also, we noticed an increase in C = O absorption due to cellulose oxidation processes.

Abstract
The efficacy of electro stimulation in epilepsy remained to be approved due to the diversity and complex effect which induced by this alternative management. So that, the objective of the study was to demonstrate the anticonvulsant methods of electro stimulation of ear points in rat with lab experimental seizure. To achieve this goal, the epilepsy rats’ model was prepared by intra peritoneal injection of pilocarpine. Seizure rats, would be stimulated electrically, it simulated as ear-point electrical stimulation with rats that treated with diazepam as a pharmacological treatment. The results revealed that the convulsion behaviours were improved in comparison to control group, but the beneficial effect was lesser than diazepam treated rat group. Basing on the results that obtained, it suggested that the electrical stimulation of certain ear-point had weak effect as anti-epilepsy, that might be get involved in decreasing the epilepsy attacks as an attempt to use a non-pharmacological management to improve epilepsy in combination with other stimulation points or longer periods.

The experiment was applied as a factorial experiment within randomized complete block design (RCBD) with three replicates. The results showed that copper spraying at concentration of 20 mg cu L−1resulted in an increase in most growth and yield characteristics, giving the highest nitrogen content in plant leaves (35.07g.kg−1), chlorophyll content in leaves (35.22 SPAD), plant height (81.01 cm), the number of branches (6.78 branch. Plant−1) and increased components of the yield by percentage of number of pods reached to (41.12%), the number of seeds by the pods (24.23%), and the number of total seed yield by (46.16%). There were no significant differences between the treatment of spray and the loss of the weight of 100 seeds. The results showed significant increase of zinc concentrations in the spray solution, where the concentration exceeded 80 mg Zn L−1in most studied traits such as content of nitrogen in plant leaves, leaf content of chlorophyll, plant height, the number of branches, and also some yield components, the pods were 15.32, the number of seeds by pods was 5.12, the total number of seeds was 4628 Kg−1, while the comparison treatment was higher in the weight of 100 seeds. The interaction between copper and zinc showed a significant effect on the content of nitrogen in plant leaves and leaf content of chlorophyll. The combination (20 mg Cu.L−1× 80 mg Zn.L−1) showed the highest mean of 37.50 g. kg−1and 37.17 SPAD for both respectively.

Published: August 2019

AbstractIn order to clarify the fundamental benefit between the relationship between the use of nanoparticles and the creation of DNA-sensing devices, using nanoparticles of zinc oxide. These particles are used in functional devices in the field of nanotechnologies in modern science, catalysts, materials used in dyes, as well as materials used in optical fields and many other high-tech applications. In this study, the effect of nanoparticles on a nuclear material and thus DNA damage is found to be deficient in the DNA and therefore the fundamental properties of the genetic material belonging toStreptococcus Mutantsspecies.This study shows how the effect of the action of nanoparticles on nanotubes on DNA is altered and changed. When the acid density is relatively high, the non-saturation is clear and distinct. This effect is dependent on the length of the DNA and the control of dsDNA By controlling the absorption obtained by zinc oxide nanoparticles.
