New material: Metal-organic frameworks for natural gas storage
Authors: Tang Jiale
Published: August 2023

As gasoline is a non-renewable source, scientists are continuing to find new sources which could replace the role of gasoline that are much cleaner and environmentally friendly. Natural gas is a good opinion as it reduces the amount of SOx, COx, and NOx being emitted and costs less compared to gasoline. The problems come as the volumetric energy density is much lower than expected. Scientists suggested three ways to overcome this challenge: CNG (Compressed natural gas), LNG (liquefied natural gas), and ANG (adsorbed natural gas). Metal-organic frameworks have been introduced for natural gas storage. The advantages and disadvantages of ANG using metal-organic frameworks (MOFs) have been discussed in detail. The quantification factors, such as gravimetric and volumetric uptake, adsorption conditions, thermal properties, and isosteric heat of adsorption usable methane capacity and morphology, are also mentioned for methane storage. Different metal-organic frameworks are compared to find the best material for methane storage. Considering all these quantification factors above between different MOFs, PCN-14 is the best MOF and has been widely used worldwide for methane storage. The paper hopes to provide state-of-the-art opinions regarding the application of MOFs in methane storage and facilitates the future of renewable energy usage.

Is space recognizing a form?
Authors: Struzik Bartlomiej
Published: August 2023

In the content of the paper, I refer to meetings with people whose reflections, general comments or even unspoken gestures have become a source of inspiration no less important to me than readings and theoretical study. At this point, I would like to particularly emphasize the role of my acquaintance with Richard Shusterman, whose concept of Somaesthetics, growing from his talent, many years of honest philosophical work and solid theoretical foundations, is probably the most striking contrast of the research method in relation to the artistic intuitions proposed in my text and postulates resulting mostly from art practice. The concepts presented in this paper, especially the two key issues of Somactive Art and space recognizing as a form, will consequently have the character of an artistic supposition and represent a theoretical sketch, rather than a thoroughly researched, well-founded, and mature scientific hypothesis.

The Dysfunction and Remedies of Copyright Registration System in the Digital Era
Authors: Zhang Feifan
Published: August 2023

In the digital age, the ever-growing development of communication technologies and their efficiency pose new challenges to the copyright registration system. Whether it is the registration demand for opuscules in the era of explosive works or the need to add the validity of registration under zero-cost dissemination, it signals a new turning point for the copyright registration system and calls for new changes. The inherent logic behind a voluntary copyright registration system lies in legal incentives and the fundamental reason for the malfunction of China’s copyright registration system in the digital age is the imperfection of intrinsic incentive mechanisms. In order to address this problem, based on the Cost-Benefit theory, the paper proposes the construction of a legal incentive mechanism for copyright registration from two aspects: reducing registration costs and increasing registration validity through intensive management, differentiated examination and an auxiliary registration system. It is expected to lower the threshold of copyright registration and meanwhile to provide practical operational standards to increase registration validity.

Authors: Ding Kehan
Published: August 2023

Depression is one of the most common mental disorder that could negatively affects individuals’ feeling, cognition and behaviour. From the cognitive modal of depression, people who have a negatively biased thinking mode tend to produce negative feeling about self, world, and their future (Beck, Aaron T, 2008). Compared to the normality, the ‘abnormal’ people tend to have a different way of interpreting things. This results from the abnormal brain functions which in turn causes cognitive deficits in depressed people. This literature review will focus on how those cognition deficits developed in children and how it causes a ‘depressed brain’. It points out people with depression usually have impairment in executive function, memory, and attention and these cognition impairments are related to the dysfunction of locus control and prefrontal cortex.
Discourse, Behavior, Identity: The Three Dimensions of Populist Agitation Nationalism
Authors: Ni Jingyi
Published: August 2023

By inciting nationalism, populism has caused a huge impact on social economy, politics, culture and other aspects. On the one hand, populism extends the influence of discourse to the whole country and incites people's nationalist emotions through the transformation of discourse system; On the other hand, in terms of behavior, it incites nationalism by means of the transformed discourse system to carryout political movements such as marches, rallies and protests for populism, with the ultimate goal of building an ideal community that truly belongs to "the people". At the same time, behind these discourses and behaviors, there is a deeper identity of exclusion, which exposes the existing problems of Western liberal society. Their emergence is due to the imperfection of the legal and political system, which makes these identities unable to enjoy due legitimate rights and interests in the society. Therefore, these people hope to incite nationalism through discourse and behavior, so as to shake the national system based on nationalism. In a word, by exploring the discourse and behavior of populism as well as the identity behind it, this paper discusses a feasible way to fundamentally solve a series of social problems caused by populism inciting nationalism.

Authors: Fei Hongmian
Published: August 2023

Chinese education in Thailand has a long history, but early teaching resources were scarce. It was not until the 21st century that Chinese education in Thailand entered a period of rapid development. This paper systematically reviews the development of Chinese teaching resources in Thailand at different stages, from different sources and of different types. It points out that the early experience of Chinese schools laid a solid foundation for the construction of contemporary Chinese teaching resources. While the development of Chinese teaching resources in Thailand has been rapid, there are still issues such as the lack of top-level design and policy implementation, insufficient teaching resources in higher education, and the need to improve the quality of Chinese teaching resources in vocational education. Suggestions are made to strengthen collaboration from a macro perspective, deepen Sino-Thai cooperation to improve localized teaching resources, and enhance the development of "Chinese + vocational education" teaching resources. These measures will further improve the construction of Chinese teaching resources in Thailand.

Published: August 2023

As a representative poet and essayist in the Qianjia period of the Qing Dynasty, Yuan Mei who styled himself Zicai with Jianzhai as his courtesy name was a scholar at the beginning and had a good reputation in his official career. However, he resigned and lived in seclusion in the 14th year of the Qianlong period after witnessing some challenges. Advocating the “spirituality” (Spirituality theory is an idea of poetry inditement and comment in ancient Chinese poetics, which is advocated most strongly by Yuan Mei in Qing Dynasty. It is one of the four major schools of poetry theory in the early Qing Dynasty, together with verve theory, style theory, and texture theory) of poetry inditement, Yuan Mei paid attention to expressing the author’s true emotion and personality. “Spirituality” put forward by him attacked the popular retro-ism and formalism in poetry at that time, which was of progressive significance, although it had limitations due to its overemphasis on subjective emotion. This paper will analyze Yuan Mei’s spirituality theory from the image and emotion of Yuan Mei’s poetry inditement.

Published: August 2023

Os processos envolvidos na arquitetura e engenharia civil estão cada vez mais influenciados por tecnologias de monitoramento e gerenciamento de dados. Neste sentido, diversos recursos surgiram para descrever conceitos modernos da automação e da indústria 4.0, sendo o Digital Twin um dos mais recentes. De maneira sucinta, um Digital Twin (DT) é um modelo virtual de um processo físico que coleta informações do mundo real e cria um protótipo de alta fidelidade. Por outro lado, a pré-fabricação pode ser definida como a manufatura de peças aptas para serem montadas no canteiro de obras. Sua lógica advém da racionalização da mão de obra e material. Visto isso, digital twin e pré-fabricados são altamente inter-relacionados e podem ser aplicados em conjunto na indústria da construção. Neste sentido, por meio de uma revisão  sistemática, este artigo tem como objetivo analisar os desafios no uso do digital twin em construções com pré-fabricados. Os resultados demonstram potenciais melhorias advindas com o uso desse recurso, mas ainda há um longo caminho a se percorrer, sendo necessário investir na integração entre todas as tecnologias necessárias para este ambiente. Além disso, é preciso aprimorar o nível de detalhe dos sensores, a fim de evitar erros de leitura e propiciar melhor atualização.

Authors: Pereira da Silva Luciano , José de Oliveira Ivanilton , Eduardo Gomes Carlos
Published: August 2023

The discussion of crimes relies on a vast literature whose debates permeate several dimensions: social, spatial, economic, and demographic, among others. The objective of this article is to understand the spatial distribution of crime in Brasilia’s Integrated Development Region. It concludes that the crime rates in this region are not randomly distributed spatially, because an exploratory analysis of spatial data indicates the existence of spatial dependence. This means that the municipalities that border the Federal District are responsible for more than 80% of the crimes carried out in the period under examination. The main victims are young people, mainly black men shot by firearms, and the proportion of young people between 15 and 19 years of age was a determining factor in this positive correlation, among other significant conditions obtained by using estimates of spatial regressions using Spatial Durbin Models – SDM and data panels for the years 2010 to 2017. We detected a 51% incidence of spillovers for fatal crimes.

Um painel dinâmico espacial do tipo Spatial Durbin Model (SDM) é utilizado e uma função não paramétrica da variável populacional para o período de 2002 a 2017. Os resultados demonstram uma associação no formato de “U” entre o tamanho da população e os gastos per capita. O ponto de mínimo de despesas é encontrado quando o município possui cerca de 13.000 habitantes. Além disso, é realizado um exercício para distinguir as implicações do tamanho populacional em subconjuntos de gastos públicos. Os resultados indicam que há espaço para reduzir o gasto público per capita tanto nos pequenos quanto nos grandes municípios. Uma alternativa para os pequenos poderia ser a formação de consórcios de municípios vizinhos na prestação de determinados serviços públicos.
Use of Reporter Assays in Monitoring Cellular Stress and Toxicity
Authors: Čáková Denisa , Jelenová Nikola , Viktorová Jitka
Published: August 2023

Monitoring the influence or process of gene expression is a very important part of research in many studies. Currently, many methods are being developed to facilitate the monitoring of gene expression regulation, the use of gene reporter assays being one of the examples. These systems represent an extensive set of tools to study the regulatory sequences of promoters, enhancers, and transcription factors. There are several assays using reporter cells to determine the biological activity of the compounds studied. The aim of this review article is to present the preparation of reporter plasmids, which is always the first step in assays using reporter genes. Subsequently, the most common types of reporter test are described, and examples of their use in in vitro testing are presented.

Published: August 2023

Organic acids in beer affect beer quality, including organoleptic properties and colloidal stability. A large proportion of the total organic acids in beer comes from the wort, while the rest is produced or transformed by yeast metabolism. Concentrations of five organic acids were determined in selected types of beer. Malic, succinic, citric, acetic and lactic acids were quantified. The concentration of acids varies according to the type of beer. The determination was made by the capillary isotachophoresis.

This paper builds on a previous one entitled “Systemic Tasks in the Teaching of Inorganic Chemistry” published in Chemické listy 9/2022, which explained the SATL method (Systemic Approach in Teaching and Learning), described the individual types of systemic tasks in inorganic chemistry, and provided examples. This paper aims to share examples of systemic tasks designed for teaching organic chemistry, which focus on developing higher-order cognitive processes. 89 teachers applied these systemic tasks in teaching 2136 second year grammar school students in the course of two school years (2019–2021). Upon verification, it was confirmed that systemic tasks enhanced students’ understanding of orga­nic chemistry and contributed to the development of cognitive and scientific skills such as critical thinking, problem-solving, cooperation, argumentation, and result interpretation. The teachers involved in this research also provided their opinions on the pros and cons of this teaching tool in terms of motivation, deeper understanding, identifying misconceptions, and time requirements.

This study describes a spatio-temporal cluster of Senecavirus A (SVA) outbreaks reported in a midwestern US slaughter plant during the summer of 2017. Data was collected on multiple site characteristics to conduct risk factor analysis. On June 8, 2017, 6 of 10 finishing pig lots delivered to the plant tested positive by reverse transcription-polymerase chain reaction for SVA RNA. Subsequently, 88 lots presented vesicular lesions at the plant, and 74 lots tested positive between June 8 and July 10, 2017, which was a significant temporal cluster.
Nutrient supplementation effects on pig performance and sickness behavior during a porcine reproductive and respiratory syndrome virus infection

Published: August 2023

Objective: Investigate how nutrient additive inclusion impacts performance and sickness behavior in pigs infected with porcine reproductive and respiratory syndrome virus (PRRSV). Materials and methods: At 10 weeks of age, 108 PRRSV naïve barrows (mean [SD] body weight: 31 [1.4] kg) were allotted into 18 pens in a commercial barn and enrolled in a 35-day PRRSV challenge study. After a 5-day acclimation period, all pigs were inoculated intranasally and intramuscularly with a field strain of PRRSV and began nutrient supplement treatments. Treatments included no nutrient supplement (control; n = 6 pens), water nutrient supplement (water; n = 6 pens), and water and feed nutrient supplement (water+feed; n = 6 pens). Pen performance was recorded weekly at 0, 7, 14, 21, 28, and 35 days post inoculation (dpi). Pig home-pen behavior was recorded on -1, 3, 6, 9, 12, 15, and 18 dpi. Results: Over the 35-day challenge, no significant differences in pig viremia or performance were reported due to treatment. Compared to control, water+feed additive increased sitting in pigs; however, no other sickness behavior treatment differences were observed. Decreased activity was observed 6 and 9 dpi. Eating was decreased 6 dpi whereas drinking was decreased from 6 dpi throughout the rest of the behavioral observation period at 18 dpi. Implications: The addition of a nutrient additive in water and water+feed had minimal effect on sickness behavior and no observed effect on viremia or performance of PRRSV-infected pigs. Decreased activity, eating, and drinking may help caretakers identify health-challenged pigs.
