Investigating Plant Community Interactions During Drought Periods Based on the Drought Coefficient-Biodiversity Effect Model: A Case Study in Xinyuan County
Authors: Li Jiali
Published: May 2023

Biodiversity and ecosystem interactions are a hot topic in environmental science. Since the Industrial Revolution, human activities have intensified the globalization of climate change, leading to changes in precipitation patterns on different continents, among which the exacerbation of drought cycles is one. To investigate the relationship between biodiversity and ecosystems under climate change, a plant species interaction model based on the Drought coefficient and biodiversity effect model is proposed in this study. This model utilized the data collected between 2008 and 2017 from Xinyuan County, China, to quantify the impact of drought on plant communities, determine the growth rate of each species, and investigate how the plant community as a whole change with the interaction among species and drought cycles. The results show that the existence of drought-resistant plants in the community can enhance the adaptability of the region to drought. Furthermore, the transformation of plant communities from competitive species to facilitative species can also enhance the overall drought resistance of the region.

Authors: Hu Rui , Zhou Xianyun , Feng Jiawen
Published: May 2023

Forests play a crucial role in carbon sequestration. A comprehensive carbon sequestration model can accurately assess the amount of carbon sequestration in forests, which can determine how to plan forests to achieve maximum carbon sequestration benefits. However, traditional carbon sequestration models only focus on the carbon sequestration of trees themselves and forest products. This article innovates and modifies the traditional model by including more indicators, such as the carbon sequestration of new growth and the carbon emissions caused by the residual material from logging. All factors that affect carbon sequestration are classified and unified in a reasonable way, resulting in a more excellent and comprehensive carbon sequestration model. Finally, this article validates and discusses the model, which shows that the model is consistent with actual results, has accuracy and predictability, and has practical value.

Published: May 2023

Due to the increasing global warming trend, the greenhouse effect is becoming more and more serious, which caused a very hot summer around the world. This study aims to identify the most important factors contributing to global warming by investigating and predicting greenhouse gas (GHG) emissions. There are not many studies to predict Canada's future GHG emissions. Therefore, It was decided to use the ARIMA model in a time series analysis to predict and simulate GHG emissions in Canada. A dataset containing seven different aspects of Canadian GHG emissions over the past 27 years was used. The result shows that overall emissions will continue to rise but the growth rate of GHG emissions will decline. Among them, Agriculture and Transportation are the two influencing factors that will increase GHG emissions the most in the future. In general, to reduce GHG emissions in the future, people need to live a low-carbon life and reduce unnecessary means of transportation or use more energy-saving resources such as electric cars. For agriculture, it takes less land to produce more food, such as hybrid rice in China. The fundamental reason is that the earth's population keeps increasing, people need more private cars to travel easily, and more food, thus increasing the area of arable land but reducing the area of green forest.

Published: May 2023

Light pollution is a new source of environmental pollution after exhaust gas, wastewater, waste residue, and noise. Research shows that light pollution is threatening people's health. In order to accurately measure the level of light pollution risk in a region, this paper established a light pollution risk index level model, and used this model to detect the level of light pollution risk in different types of places. Specifically, by determining the main factors that affect the risk of light pollution, and searching for corresponding data indicators from different countries to calculate the weight, this paper uses a combination of entropy weight and coefficient of variation to obtain the index weight, and establishes a light pollution risk index level model based on the weight. Finally, the model is applied to four specific types of locations to determine their risk level of light pollution.

Authors: Ren Anqi , Cai Yanan , Li Qingwei
Published: May 2023

[Objective] To investigate the salt resistance growth status and photosynthetic characteristics of Prunus mume and saline-alkaline resistance of different Prunus mume varieties against mixed salt stress, aiming to provide scientific basis for the application of Prunus mume in saline-alkali land. [Methods]. Taking the Prunus mume 'ZaohuaLve' and Prunus mume 'Meiren' under two years of cutting seedlings as examples, NaCl and NaHCO3 were prepared into treatment solution at a molar mass ratio of 1:1, with six gradients (i.e., 0 (CK), 100 (S1), 200 (S2), 300 (S3), 400 (S4) and 500 (S5) mmol L-1) to observe the growth status and photosynthetic reaction of test plants under different salt concentrations. [Results] With the increase of salt treatment concentration and stress time, the growth amount of leaf length, leaf width and ground diameter of the two kinds of Prunus mume decreased, and the Prunus mume 'ZaohuaLve' salt tolerance threshold (330.189 mmol L-1) is greater than Prunus mume 'Meiren' (292.453 mmol L-1). On the other hand,  the chlorophyll content of the two Prunus mume increased first and then decreased, and the maximum, actual quantum yield of PS Ⅱ and photochemical quenching coefficient decreased as a whole. The net photosynthetic rate (Pn), stomatal conductance (Gs), and transpiration rate (Tr) of the two Prunus mumes decreased overall. For the Prunus mume 'ZaohuaLve', Ci values increased at 0 - 10d, and the changes were inconsistent in Pn, Gs and Ci at later stages of salt stress. The overall trends in the Pn, Ci, and Gs values of Prunus mume 'Meiren' were consistent for the 100 and 200mmol L-1 treatments. [Conclusion] The growth index and photosynthetic index of the two Prunus mumes in the early stage of salt stress are not obvious with salt tolerance. The Prunus mume 'Meiren' salt stress was dominated by stomatal restriction in the early stage, while non-stomatal restriction was the main factor affecting photosynthesis in the later stage. By contrast, the two factors may coexist simultaneously in the Prunus mume 'Meiren'. Overall, the Prunus mume 'ZaohuaLve' was stronger than Prunus mume 'Meiren' regarding the saline-alkaline resistance.

Authors: Liu Jingwei
Published: May 2023

Concrete material is a cement-based material widely used in various projects. Under the load, the concrete structure will be damaged to produce cracks. Therefore, it is very necessary to accurately locate the damage point during detection. Acoustic emission (AE), as a nondestructive testing technology that monitors concrete damage, can be used to record and analyze the transmitted acoustic signal through a sensor so as to determine the source of the wave. Time difference location method is a commonly used sound source location algorithm at present. It regards the propagation of sound wave in concrete as a fixed value and does not consider the effect of acoustic wave attenuation, resulting in poor positioning accuracy. Resulting in poor accuracy of location point. This paper firstly introduces the principle of time difference positioning method. Following that, an analysis and summary of the influence on the water-cement ratio, sand rate, including aggregate particle the magnitude of sound wave attenuation is provided. The existence of acoustic attenuation is verified by the designed test scheme, and the optimization algorithm is obtained by using exhaustion method and interval dichotomy method. Compared with the time difference localization method, this algorithm can locate the damage point more accurately.
Application And Improvement of Composite Materials in Truss Bridge Structure
Authors: Zhang Yiyi
Published: May 2023

Composite materials are new materials with the features of light weight, high strength, high specific modulus, strong corrosion resistance, and aging resistance. The truss structure is subject to unidirectional force, which gives full play to the advantages of high strength of composite materials along the fiber direction. Therefore, composite truss structure is gradually attracted attention in engineering fields, i.e., aerospace, bridges, and construction. By analyzing the application status of composite truss bridge at home and abroad, it can be concluded that compared with traditional steel truss, composite truss bridge has advantages in flexural performance, tensile performance, stability and other mechanical properties. However, due to the stiffness control design, the strength of composite material is not fully utilized, and the structural reliability of composite truss bridge is low due to the low efficiency of structural joints. The improvement methods of these two problems are reducing the allowable deflection-span ratio of composite truss bridge design and using composite materials with greater stiffness and changing the laying Angle and laying proportion of composite materials, respectively.

As the capital of Anhui Province and the sub-center of the Yangtze River Delta urban agglomeration, Hefei has been increasing its regional status in recent years, and the city's spatial planning has gradually matured and becomes unique. This paper takes Hefei city as an example to explore the process of urban morphological evolution and its dynamic mechanism, describe the unique fan-type morphology of the city, and discuss the key factors and laws of its spatial and morphological development. Results show that Hefei was mainly a "doughnut-shaped" city before the founding of the People's Republic of China. After its founding, Hefei gradually formed a "fan-shaped" urban, extending to the present. The "fan-shaped" urban form can be subdivided into three modes: one-center with three-fan, one-center with multiple-cluster, and double-center with multi-cluster. In terms of the dynamics of urban form, modern urban planning theory lays the foundation of spatial form development, industrial development is the main driving force of spatial form development, and the economic system is the way to regulate spatial form development. The current spatial form pattern of Hefei is the result of the interaction of these factors.
The Application of The Indigenization Technique in Modern Chinese Church Architecture
Authors: Hong Linqi , Qiu Yi , Zhu Ruining
Published: May 2023

"Indigenization" is a process that presents a blend and adaptable feature by combining foreign elements with the local natural environment and cultural factors. Church buildings are the most tangible manifestation of the "indigenization" of Christianity. This paper discusses the application of indigenization techniques in modern Chinese Catholic church architecture from four aspects: layout, structure, materials, and decoration. In terms of layout, indigenization is reflected in space, plan, and orientation. The space mainly imitates traditional Western-style churches and simplifies with the simplification of function. In terms of plan form, the basic rectangular space is retained and combined with local architectural features to evolve into some new variants. Orientation, some churches have absorbed local building orientation patterns. In terms of structural indigenization, the main materials are stone, brick, and soil, and the building structure is mainly supported by load-bearing walls and wooden beams. In terms of material selection, indigenization techniques are mainly based on regional resource conditions and are combined with the characteristics of local residences and climate conditions. The choice of building materials is made by considering the availability, processing difficulty, and physical properties of materials. The application of decorative indigenization often borrows common decoration techniques from local residential buildings and combines them with traditional Chinese culture to create a unique Chinese and Western fusion style building, making the church better integrated into the local architectural community and accelerating local residents' acceptance of Catholicism.

Research on Cooperation Incentives for Emergency Logistics Capacity Reserve from Humanitarian Organization Perspective
Authors: Wan Zhongjun
Published: May 2023

Recently, catastrophic events have occurred frequently, seriously threatening the safety of people's lives and property. The uncertainty in the demand for emergency logistics resources poses a huge challenge for emergency stockpiling. From the perspective of humanitarian organizations, cooperation with third-party logistics providers for emergency logistics capacity reserve can improve the efficiency and reduce the cost of reserve. However, in practice, there is a lack of unity of purpose, capacity mismatch and information asymmetry between the two rescue parties, which makes cooperative emergency reserve a problem worth studying. This paper addresses the emergency logistics capacity reserve problem and take a two-level supply chain consisting of humanitarian organization and third-party logistics provider as the research object to explore the cooperative reserve model between the two sides. This paper establishes a Stackelberg game model with humanitarian organization as the leader and third-party logistics provider as the follower based on the premise of mutual cooperation. Under different incentive models of cooperation, the humanitarian organization executes the price decision to minimize the deprivation cost and disaster relief cost, and the third-party logistics provider executes the stockpiling decision to maximize the revenue. Secondly, this paper discusses the equilibrium decisions of both sides of the game under different scenarios and provides corresponding numerical analysis. Finally, this paper finds that for the possible moral hazard problem of third-party logistics provider, humanitarian organization incentives and government subsidies have a positive effect on third-party logistics provider's stockpiling; while the effect of corporate reputation depends on their donation behavior.

Joanna Mary Boyce: un pellegrinaggio preraffaellita in Umbria
Authors: Morelli Michela
Published: May 2023

Sin dalla metà del XIX secolo l’Umbria è una terra di scoperte per diverse pittrici preraffaellite provenienti dall’Inghilterra, le quali interpretano pittoricamente l’“incanto” del paesaggio e della cultura locale. Il loro interesse si concentra sui luoghi più remoti della regione caratterizzati da un isolamento spaziale, culturale e sociale che, ai loro occhi, conferiva alle hill towns umbre la fisionomia di comunità antiche perfettamente conservate e vive. È questo il caso delle impressioni ricavate dal soggiorno a Todi nel 1857, dalla pittrice Joanna Mary Boyce, testimoniate da alcune lettere e da un taccuino di schizzi di viaggio fondamentali per la realizzazione di uno dei suoi più fortunati dipinti: The Departure – An Episode of the Child’s Crusade (1857-1861). L’attenzione delle artiste-viaggiatrici (tra le quali si ricordano anche Evelyn Pickering De Morgan e Marie Spartali Stillman) al paesaggio umbro, all’arte e alla storia delle piccole città contribuisce a nutrire la leggenda preraffaellita dell’“enchanted” Umbria. Questo preciso immaginario, profondamente caratterizzante e destinato a riadattarsi ai tempi o a venire ribaltato per reazione nella cultura artistica del Novecento italiano ed europeo, è sintetizzato e discusso anche nel volume A Little Pilgrimage in Italy (1911) di Olave Muriel Potter.
Il corpo distopico e il corpo utopico nei graphic novel di Zuzu
Authors: Lacalandra Gaetano
Published: May 2023

Questo studio si occupa di inserire la graphic novelist italiana Zuzu in quella corrente internazionale di fumettisti (Spiegelman, Sacco e Satrapi) che per mezzo dei loro graphic novel di genere autobiografico presentano esperienze personali intrise di valore politico, seguendo il concetto de ‘il personale è politico’ coniato dalla femminista Carol Hanisch. Giulia Spagnulo, in arte Zuzu, ci mostra l'immagine del corpo distopico nel primo graphic novel pubblicato, Cheese (2019). Qui, la protagonista Zuzu, affetta da bulimia, porta a compimento il percorso di guarigione dal disturbo alimentare grazie soprattutto al legame di solidarietà instaurato con i suoi amici. Nella seconda opera pubblicata, Giorni Felici (2021), l’autrice rappresenta invece l’immagine del corpo utopico. Attraverso il continuo richiamo al testo teatrale di Samuel Beckett Happy Days, l'autrice racconta la storia di Claudia e del suo tentativo di appropriazione del corpo utopico, mostruoso e capace di commettere violenza, che supera la dipendenza affettiva, guadagna amor proprio e raggiunge l’accettazione di sé. Entrambe le protagoniste riescono nel loro obiettivo di realizzare una ‘azione utopica’, ovvero il tentativo di apportare un cambiamento positivo nella loro vita in relazione a un malessere generato da una problematica interiore e personale, aspetto che segna la differenza più importante con le opere di Spiegelman, Sacco e Satrapi.

Published: May 2023

Feed is widely recognized as the most crucial component of livestock production systems, accounting for up to 70% of production costs. The existing gap between the supply and demand of fodder is a matter of significant concern. To minimize wastage and enhance animal production, fodder crops can be preserved as silage, haylage, or hay for feeding purposes. Maize silage stands out as a favored option due to its higher yield, acceptable nutritional content, and the presence of water-soluble carbohydrates that can be fermented into lactic acid. Additionally, it provides an economical source of fiber and starch that complements grazing for a substantial part of the year. When incorporating high levels of maize silage supplementation, optimizing milk solids output requires addressing dietary deficiencies in protein, minerals, and occasionally fiber. Although certain losses naturally occur during fermentation and storage, improving management techniques can help reduce them. Over the years, the in-situ approach has been widely employed to assess the expected digestibility of feed components in ruminants. This approach is a valuable tool for predicting the rumen degradability of organic matter derived from the diet. To address these challenges, it is imperative to identify non-conventional feed sources or encourage farmers to cultivate more nutritious fodder varieties.

The inscriptions CIL XIII 8825 = Dessau 9186 and CIL XIII 8828, in which the governor of Germania inferior Q. Venidius Rufus is mentioned, were incorrectly restored, mainly because it was not remarked that the title consularis can also be placed in front of the name. The paper provides here a reconstruction of the two texts.

Published: May 2023

Investment in a new language restructures the prevailing ideologies through its potential as an alternative resource in the future linguistic market. This resource modifies the learners’ existing identities with the imagined identities of this new resource. This study aims to explore how learning Chinese language evolved as an investment in the education sector of Pakistan to construct an alternative identity in the future linguistic market. Under thematic analysis, in-depth interviews of the stakeholders investing themselves at various levels in promoting, learning, and teaching Chinese were analyzed with power discourse as the theoretical framework. Darvin and Norton’s (2015) model of investment was used as analysis model to investigate how investing learners in Chinese is reshaping their current identities in a structured habitus of shifting ideologies. The findings show a corresponding relationship of Chinese with a powerful economy, innovative technologies, and higher education. The major themes focus on the Chinese as an alternative resource with better employment potential in the future job market. This serves as a better alternative linguistic resource to improve the learners’ social and economic capital. This is where learners of this language invest themselves at different levels of the education sector in Pakistan to re-envision their future identities.

The researchers focus on the TPACK framework, which is used to assess teachers' understanding of how to use technology in the classroom. The goal of the model is to define the skills and knowledge teachers need to effectively integrate technology into their lessons. Teacher educators’ can better prepare their students for the problems of the modern world by applying the TPACK. Teachers need to have a high level of the ability to integrate their knowledge of subject matter, pedagogy, with the integration of technology. In the Pakistani setting, there is still a lack of technological integration in educational settings. The purpose of this research was to determine how well teacher educators in Karachi, Pakistan, use TPACK and associated domains in their classrooms for the preparation of future teachers. Teacher educators from private teacher education institutions of Karachi were conveniently sampled for this quantitative survey research study. Data was analyzed using SPSS, and the study's measurement and structural models were put through their paces using Smart PLS. It is one of the more sophisticated programs for structural equation modeling that uses partial least squares (PLS-SEM). The study found that teachers educators' technology and technological pedagogical knowledge significantly effects on their TPACK in a positive way. Conclusions and suggestions for further research are provided for implementing the TPACK framework in teacher education programs and designing learning strategies for enhancing instructors' pedagogical skills in light of the study's findings.

The Influence of Pain and Anxiety on the Pain Perception and Outcome of Extracorporeal Shockwave Lithotripsy
Authors: TÜRKMEN Nihat , KUTSAL Cemil
Published: May 2023

Abstract

Introduction: In this study, we aimed to investigate the effect of depression and anxiety presented before ESWL on pain perception during ESWL.

Materials and Methods: A total of 60 kidney stone patients who underwent ESWL between October 2019 and November 2020 were enrolled in the study. Patients' age, sex, body mass index (BMI), and stone parameters were recorded. The patient's anxiety and depression states were evaluated using the Hospital Anxiety and Depression Scale (HADS) before the first session. The pain level was assessed by using the visual analog scale (VAS) after the first session.

Results: There was no statistically significant difference between the anxiety, depression, and VAS scores (p>0.05). The association between anxiety and depression scores and the procedure's success was also evaluated, and no significant association was found (p>0.05). Furthermore, there was no association between VAS score and patient’s age, sex, BMI, the distance from skin to stone, and stone size (p>0.05).

Conclusion: Our results do not show a significant correlation between pre-ESWL depression or anxiety with the VAS score measured after the procedure.
