The Research on Cartoon Image Design And Application of Main Characters in The Legend of the White Snake
Cartoon images are one of the important carriers for the inheritance of folk literature and culture. We should pay attention to the positive role of cartoon images in the inheritance of intangible culture. So the study aims to design and develop cartoon images of main characters in the Legend of the White snake based on audience intention. So that the cartoon image can be endowed with historical and modern cultural connotations. In this way, it can play a role in inheriting intangible cultural heritage and enhance the cultural confidence. Through the combination of qualitative and quantitative method, it compared the main characters of the Legend of the White snake at home and abroad. After carrying out desk research on the historical background of the legend, we used the concept of participatory design to conduct a questionnaire survey on the preference of cartoon images and analyzed the problems of character design, carrier, communication, and etc. Finally, based on the audience's extraction and combination of design elements, the cartoon image of the main characters in the Legend of the White Snake was generated, which meets the perceptual needs of modern people. By making full use of the narrative function of cartoon images, the creatively designed cartoon images of the main characters in the Legend of the White Snake are deeply rooted in the hearts of the people. It can also raise public interest in the culture of the White Snake and arouse emotional resonance. In this way, it promotes the inheritance and development of the intangible cultural heritage, the White Snake, and provides a certain reference for the design of cartoon images of similar characters in folk literature
Status and Influencing Factors of HIV/AIDS Patients Co-infected with Hepatitis C Virus in Guizhou
Background The status of patients with HIV/AIDS co-infected with HCV considerably varies in different parts of China. The co-infection of HIV and HCV accelerates the clinical progress of the disease, thereby reducing the patients' quality of life and exacerbating the occurrence of death. Currently, there are relatively few studies on patients with HIV/AIDS co-infected with HCV in Guizhou. Objective To analyze the status of patients with HIV/AIDS co-infected with HCV in Guizhou and its influencing factors and consequently provide basis for its early detection, diagnosis, and treatment. Methods The cases included in this study were a cohort of HIV/AIDS patients who received antiviral therapy (ART) in the public health rescue center of Guangzhou from March 2006 to December 2020. Finally, 3 084 patients who met the study requirements were included. Patients' sex, age, ethnicity, education level, occupation, marital status, route of infection, year of diagnosis, and CD4+ T-lymphocytes before ART and anti HCV levels were collected. Multivariate Logistic regression model were used to identify influencing factors of patients with HIV/AIDS co-infected with HCV. Results Among the 3 084 patients with HIV/AIDS, 202 were co-infected with HCV, and the co-infection rate was 6.55%. There were significant differences in HCV infection rates among patients with HIV/AIDS of different age groups, education levels, occupations, route of infection (P<0.05) . There were no significant differences in HCV infection rates among patients with HIV/AIDS by gender, ethnicity, and marital status (P>0.05) . The prevalence of HCV infection among HIV/AIDS patients tended to decrease with increasing year of diagnosis and increasing levels of CD4+ T lymphocytes (P<0.05) . Multivariate Logistic regression analysis showed that the risk of HCV infection was higher among HIV/AIDS patients aged 30-39 and 40-49 years than among those ≥50 years〔OR (95%CI) =2.512 (1.374, 4.593) , 2.802 (1.521, 5.163) , respectively〕, and the risk of HCV infection was higher among HIV/AIDS farmers than among those in other occupations〔OR (95%CI) =1.926 (1.201, 3.090) 〕. Route of infection of intravenous drug user was higher for HIV/AIDS patients with HCV infection than for MSM〔OR (95%CI) =39.038 (17.559, 86.790) 〕, and for HIV / AIDS patients diagnosed 2006—2010, 2011—2015, the risk of HCV infection was higher than that for those diagnosed 2016—2020〔OR (95%CI) =10.890 (6.428, 18.447) , 4.613 (2.928, 7.269) , respectively〕. Those with baseline CD4+ T lymphocytes <200, 200-350, 351-499/μl had higher risk of HCV infection among HIV/AIDS patients than those with baseline CD4+ T lymphocytes≥500/μl, respectively〔OR (95%CI) =7.120 (3.731, 13.589) , 3.614 (1.818, 7.184) , 2.795 (1.319, 5.922) 〕. Conclusion Although the strategy of "exhaustive treatment" for HIV/AIDS has decreased HCV infection rates among patients with HIV/AIDS in Guizhou, the status still need to be carefully monitored. Early HCV screening should be conducted for the HIV/AIDS population, focusing on individuals aged 30-49 years, intravenous drug users, farmers, and those with low CD4+ T-lymphocyte levels
The role of the post-heat treatment on the Cr-based precipitates and related room temperature mechanical properties of the sintered Nb-lean Cu–Cr–Nb alloy
Nb-lean Cu–Cr–Nb alloys have been widely applied in electrical industries as the structural conductive material owing to their excellent combination of the mechanical and electrical properties at room temperature. In this work, the influence of temperature during fast sintering and post-heat treatment strategies on the precipitate evolution and room temperature mechanical properties of the Cu–3Cr-0.5Nb (wt.%) alloy was investigated. The increasing sintering temperature will improve the density and mechanical properties of the alloy without any obvious grain growth during this non-equilibrium process, while the post-aging at lower and higher temperatures can effectively control the formation and coarsening process of the Cr-based precipitates. Systematic characterization was then conducted on the microstructural evolution, especially the altering precipitates’ size and distribution, in the alloy at both as-sintered and the aged conditions, which is correlated to its room temperature tensile properties. Lower aging temperature will induce the nucleation of the new Cr2Nb precipitates without causing a significant coarsening of the existing precipitates like aging at higher temperature. Therefore, the low-temp. aged sample exhibits the highest tensile strength and elongation due to the enhanced Orowan strengthening mechanism induced by its unique precipitate microstructure

Microexplosion under Microwave Irradiation: A Facile Approach to Create Mesopores in Zeolites
A facile
microexplosion approach has been successfully developed to produce
an interwoven mesopore network in zeolite crystals via the rushing-out
of gases generated by decomposition of H<sub>2</sub>O<sub>2</sub> under
microwave irradiation. This “gas imprint” method creates
the mesopores from the interior crystal toward the exterior, in line
with the direction of the pristine microporous channels, and is different
from the previous methods in which the reagent starts an attack from
the crystal surface and perforates inward. The created mesopores extend
throughout the whole crystal and highly blend into the intrinsic micropores
around. The acidity of zeolite is also well preserved due to this
unique mechanism of pore creation. The continuous high quality hierarchical
architecture with intact acidity leads to a notable increase both
in the conversion of 2-methoxynaphthalene acylation and in the selectivity
to the target molecule of 2-acetyl-6-methoxynapthalene. This microexplosion
approach offers an efficient synthesis protocol of zeolitic hierarchy
integrating intersected mesoporosity and zeolitic microporosity and
opens the way to the rational organization of meso- and microporosity
for maximal advantage in applications
Dehydration of Glycerol to Acrolein over Hierarchical ZSM‑5 Zeolites: Effects of Mesoporosity and Acidity
Selective dehydration of glycerol
to value-added acrolein is an
interesting catalytic process not only owing to the increasing coproduction
of glycerol in the biodiesel production but also due to the emerging
perspectives to provide a sustainable route for acrolein production.
The use of zeolites in glycerol dehydration is a very promising way
with high performance, but these microporous catalysts are often severely
constrained by the rapid catalyst deactivation due to coke formation.
Although the introduction of hierarchical structure in microporous
zeolite crystals is believed to be an effective approach to enhance
their activity and lifetime, the relationship between the mesoporosity
and catalytic performance is still controversial. In this paper, four
kinds of typical hierarchical ZSM-5 catalysts with diverse mesoporosity
and similar microporosity/acidity are prepared by the salt-aided seed-induced
route. By systematically studying their catalytic performances, the
effects of various mesopore types on the glycerol dehydration are
declared, including pore size, amount, distribution, and connectivity.
The sample with open and interconnected mesopore architecture display
the high activity, long lifetime, and improved selectivity, while
the worse behavior of closed and small mesopores is attributed to
the mass transfer limitations and/or the in-pore condensation of reactant
or its heavier derivatives. Moreover, the combined effect of acidity
and hierarchical structure was also explored by changing the framework
Si/Al ratio. The findings emphasize the necessity of reasonably designing
the zeolite catalysts with proper hierarchical structure and acidity
for maximal catalytic advantage
