Objective: This work focused on the effect of “linear-rise” amplitude modulated waveform on the time evolution of some typical electrical and plasma parameters in a pulsed radio-frequency capacitively coupled argon discharge. Methods: The pulse-on phase of a square wave pulse is divided into two distinct stages, namely, the “linear rise” phase (T1 phase) and “constant amplitude” phase (T2 phase). The study focused on exploring the impact of varying T1 durations on the temporal evolutions of these parameters. In the experiment, the electron density was measured time-resolved by a hairpin probe. Phase-resolved optical emission spectroscopy was employed to determine the spatial-temporal distribution of the electron impact excitation dynamics. Additionally, we determined the amplitudes and the relative phase of the discharge voltage and current, as well as the power deposition by analyzing the waveforms obtained from a voltage and a current probe. Results: It was found that with the increase of T1, the critical voltage value required for the plasma ignition becomes lower, and the RF power and the light intensity overshoot less significantly. Upon the overshoot, the plasma when the light intensity exhibits the maximum is dominated by the “overshoot” mode. After the pulse is turned off, the electron density under different T1 durations first decreases with the same rate, and then the decay rate is decreased with the increase of T1. This is because for a longer T1, the neutral gas temperature gets lower, leading to a higher density of neutral gas, so the electron diffusion loss is suppressed. Conclusion: Compared to the square pulse modulated radio frequency capacitively coupled plasmas, the “linear rise” amplitude modulation approach introduces external control knobs to modulate the plasma parameters, which benefits practical material processing. This paper is an experimental measurement implemented in an electropositive gas Ar discharge, and is expected to be extended to the plasmas operated in complex electronegative gases in the future.

Objective: In recent years, the anticancer effect induced by cold atmospheric plasma (CAP) has received much attention and has become a rapidly growing research topic. The purpose of this article is to study the anticancer effect of CAP combined with drugs to seek more efficient anticancer therapy. Methods: The plasma source used in this study was surface air discharge plasma, and the anticancer drug was thymidine (TMD). Breast cancer cells (MCF-7) and cervical cancer cells (HeLa) were treated in vitro to evaluated the anticancer effect of the combination of the two therapy. The anticancer efficiency was assessed by detecting cell viability and cell apoptosis rate. And the combined anticancer mechanism was further analyzed by measuring intracellular reactive oxygen species (ROS) levels. Results: The results of cell viability and cell apoptosis showed that the combined anticancer effect of plasma and TMD was significantly better than TMD treatment alone, but not as good as plasma treatment alone. Intracellular ROS levels were increased by plasma treatment of MCF-7 and HeLa cells, and ROS played an important role in plasma-induced apoptosis of cancer cells. In addition, TMD didn’t induce intracellular ROS production, but only interfered with DNA replication and normal division of cancer cells and could increase the stress of cell division, thus inducing apoptosis of cancer cells. Conclusion: TMD may interfere with the targets of plasma action and affect the anticancer effects of plasma, which indicated that not all anticancer drugs can achieve synergistic effect with plasma, and some drugs even interfere with plasma action.

A anatomia da parede abdominal é composta principalmente por 4 músculos, oblíquo externo e interno, transverso e reto abdominal. Conhecer a anatomia desses músculos e os fatores que podem influenciar nela, como a formação embriológica, a obesidade, e a força muscular, são de extrema importância para compreender o surgimento de hérnias abdominais, principalmente em pacientes obesos. Logo, a estrutura anatômica abdominal reflete muito no desenvolvimento de hérnias nesses pacientes, cuja anatomia está distorcida. Dessa forma, com o crescente corpo de literatura sobre a influência da parede abdominal no surgimento de hérnias em pacientes obesos, foi possível a realização de uma revisão integrativa de literatura por meio da plataforma pubmed, com seleção e análise criteriosa dos artigos, a fim de revisar e analisar as evidências atuais sobre o impacto da distorção anatômica da parede abdominal dos obesos no surgimento de hérnias. Nesta revisão foi identificado que a obesidade naturalmente é um fator de risco significativo para o surgimento de hérnias abdominais, especialmente quando associada à fraqueza muscular e à distensão abdominal. Em pacientes obesos, a pressão intra-abdominal aumenta devido ao excesso de tecido adiposo, levando a um enfraquecimento e distensão do abdômen, e consequente surgimento de hérnias. Além disso, a anatomia da parede abdominal também desempenha um papel importante, como os defeitos na linha alba e nas regiões inguinais, que são as áreas mais frequentemente afetadas. Portanto, é evidente que a anatomia abdominal influencia no surgimento de hérnias em pacientes obesos. Isso acontece devido aos níveis baixos de colágeno tipo I e tipo III na linha média da parede abdominal, que podem desempenhar um papel fundamental no desenvolvimento da diástase do músculo reto abdominal. Ademais, a obesidade associada a uma redução na massa corporal magra apresenta grande influência no surgimento de hérnias da parede abdominal, além do risco aumentado de complicações.

Effects of Silkworm Pupae Protein and Active Peptides on Human Immunity
Authors: Wang Jiayi
Published: December 2023

The escalating global population and the concomitant scarcity of protein resources have heightened the urgency to explore novel sources of protein. Insects, as a taxonomic class of organisms, are abundantly enriched with superior-quality protein and steered by this premise, they present a prodigious opportunity for human employment and scientific investigation in the realm of biologic resources. The larval stage of the domesticated silkworms, extensively cultivated for their silk, give rise to the universally consumed pupae in East Asia that augment the dietary provisions. This paper provides a comprehensive discussion of the immune-boosting, antibacterial, antitumor, and antioxidant properties of silkworm pupae proteins. Additionally, it explores the possible allergic reactions that may arise from silkworm consumption. Silkworm chrysalis protein, which contains a plethora of bioactive peptides such as AKPGVY and AAEYPA, offers a novel source of antioxidant peptides that have been shown to bolster immune function, enhance the body's capacity to fend off bacteria and viruses, reduce the risk of tumor development, and mitigate adverse effects such as free radical oxidative damage. However, it is important to note that some individuals may be susceptible to allergic reactions to silkworm pupae. Consequently, safety concerns related to the use of silkworm pupae proteins and active peptides should be taken into account.
Association of Gut Flora and Short-Chain Fatty Acid Metabolite in Functional Constipation and Regulation of High-Fibre Diet on Them
Authors: Cai Yuwei , Chen Siyu , Zhang Weixi
Published: December 2023

Constipation is one of the most prevalent diseases in the world, and it has a significant impact on the quality of life of people. There are several critical factors associated with constipation, including short-chain fatty acid content and the composition of the gut microbiota. A disorder in any of these factors can cause an abnormal bowel movement and the symptoms of constipation. Diet regulates the gut microbiota and influences the immune system. Recent research suggests that high fibre foods promote the growth and stabilization of the intestinal nerves, as well as an increase in the number of useful bacteria found in the intestines. Fibre deficiency increases the risk of GI distress and contributes to poor gastrointestinal motility. Long-term treatment of constipation is dependent on developing a diet that provides sufficient fibre. A high fibre diet is probably not just essential to manage constipation, but also to lower the risk of developing other chronic illnesses associated with diet. In this paper, the relationship between high fibre diet and microbiota and short chain fatty acids in constipation patients is analyzed.
Circadian Rhythm and Obesity
Authors: Guan Xueting
Published: December 2023

Obesity with significant implications for public health has become a global epidemic. Recently, there is growing evidence indicating that the disturbance of circadian rhythms have a pivotal role in the onset of obesity. Insufficient sleep, a common consequence of modern lifestyle, further disrupts circadian rhythms and always leads to higher body mass index (BMI) and metabolic disturbances. Circadian misalignment affects various aspects of metabolism, including appetite regulation, glucose metabolism, and lipid metabolism. Disturbances in the timing of food intake, such as late-night eating or irregular meal patterns, can disrupt the synchronisation between the circadian clock of suprachromaffin nucleus and peripheral clock, resulting in impaired metabolic function and increased adiposity. Circadian clocks oversee expressions of crucial genes associated with the energy balance and lipid metabolism at the molecular level. Genetic studies have identified specific clock genes that are related to metabolic disorders and overweight. Perturbation of genes is regulated by the body's internal clock, including those responsible for adipogenesis and insulin signaling, acts as a major player in the progression of obesity. Understanding the relationship between circadian rhythms and obesity has important implications for preventive and therapeutic strategies. Implementing interventions that restore circadian alignment, such as timed light exposure, sleep optimization, and following regular meal timing, may help mitigate the risk of obesity and its associated metabolic complications. This article reviews the current literature on the influence of circadian rhythm on obesity and explores its underlying mechanisms.

Authors: Yang Zhihong , Li Guangzhuang , Hou Yunhua
Published: December 2023

The pulp made from wheat straw fiber contains considerable natural cellulose, but there are more carbohydrate-ferulic acid ester-lignin cross-linking structure in the pulp. this cross-linking structure seriously hinders the recognition and binding of hemicellulase and substrate, thus affecting the efficiency of hemicellulose degradation. Feruloyl esterase, as one of hemicellulose degradation enzymes, can hydrolyze hemicellulose side chain branches. Make the plant grid structure loose, it is more important that it can enhance the accessibility of xylanase to the xylan trunk. Therefore, it is of great significance to apply it to the synergistic xylanase-assisted bleaching of wheat straw pulp.
The Significance of Sodium-Potassium Pump (Na⁺, K⁺-ATPase) in Neural Signaling
Authors: Ma Yunyan
Published: December 2023

Neural signaling is the significant process that allows the human brain to pass down cell signals across the body. The neurons inhibit in the brain and pass down information from the axons on one neuron to the dendrites on another. This process is enabled through the concentration gradient regulating effect of the sodium/ potassium pump (the Na/ K pump). Facilitating the flow of Na+ and K+ions, the concentration gradient generated creates an action potential. The neurons open and close their voltage gated channels to change voltage potentials, de- and repolarise local membranes and secrete neurotransmitters. The series of processes collectively allows the transmission of information through the human body (Stillwell 431). Understanding the process of neural signaling brings new insights into how our brains communicate information to our body and essentially dictates our day to day life.

Published: December 2023

By using microcapsule technology, the components that may react with each other can be made into microcapsule products respectively, so that they can be stabilized in a system, and each effective component can be released in an orderly manner and act at the corresponding time, thus improving the flavor and nutrition of the products. In order to further find an efficient and reasonable cigarette flavoring process, this study used gelatin and Arabic gum as composite wall materials to synthesize mint-flavored microcapsules by complex coacervation. Firstly, gelatin-Arabic gum dispersed peppermint oil in water medium to form micro-droplets, then the pH value of the system was adjusted, the solubility was reduced and condensed into capsules, and then glutaraldehyde was added for curing reaction. The test results show that the embedding efficiency of microcapsules is the highest when the mass ratio of mint essence to two sustained-release materials is 1:9. When the dosage of mint-flavor microcapsules is 10 ~ 15 mg/ cigarette, the aroma of cigarettes increases obviously, the irritation decreases, and the aroma of wild mint essential oil can also be coordinated with the cigarette aroma. The results show that the samples of mint-flavor microcapsules synthesized in this study greatly improve the aroma characteristics and smoking characteristics of cigarettes, which lays a foundation for the brand development of cigarettes and has a good application prospect.

Published: December 2023

Climate change poses a huge threat to life, especially climate change caused by greenhouse gas emissions. Positive actions should be taken to reduce greenhouse gas emissions. But simply reducing emissions is not enough. It is necessary to increase carbon dioxide reserves through biosphere or mechanical means. Forests in the biosphere can store carbon dioxide. Moderate deforestation can increase the amount of fixed carbon dioxide and have little impact on society. For this issue, this article selects Saihanba Forest Farm as the research object. By establishing a mathematical model, the impact of different forest management schemes on the carbon dioxide absorption capacity of Saihanba Forest Farm was analyzed. This paper selected four main variables to reflect their impact: forest coverage, forest volume, forest volume at different ages, and water conservation. The entropy method and TOPSIS comprehensive evaluation method are used for the data in the variables. The results showed that near mature and mature forests contributed the most to carbon dioxide absorption, while over mature trees contributed the least to carbon dioxide absorption. Based on the results, this paper presents the optimal forest management plan, and suggests that managers should appropriately cut down over mature forests to increase the stock of near mature and mature forests.

Assess the benefits of ground- source-heat pumps for residential heating versus natural gas boilers in the UK
Authors: Sun Weihao
Published: December 2023

Some basic introduction about the current background of heating in the UK and ground source heat pumps (GSHPs) and natural gas (NG) boilers was outlined in this report. Moreover, this report also provided a detailed literature-based review of previous studies of both GSHP and NG boiler, concentrating on environmental impact, costs and benefits. For the purpose, a 12kW peak heating load house which is located in London established by the IES VE have been considered as the case study. Finally, it is concluded that the coefficient of performance (COP) of GSHP should be higher than 2.2 to achieve lower carbon emissions compared with NG boilers in the current period. And under normal conditions, the efficiency of the GSHP is in the range of 2.2 to 4, so it is more environmentally friendly than the NG boiler. As for a GSHP with a COP of 4, it has been found that the carbon emissions will be reduced by about 25% in the current period, 40% in 2030 and even 90 percent in 2050 after replacing the NG boiler. Besides, the results show that using low operating temperatures will contribute to reduce carbon emissions. In the aspect of economic, it can be concluded that the installation of the GSHP is cost-effective in most cases and the higher the COP, the shorter the payback period. Under the subsidy of Renewable Heat Incentive (RHI), for a GSHP with a COP of 4, its payback period is about 20 years. However, if the COP is lower than 2.6, the capital costs cannot be fully recouped. In the end, the results and the limitations occurring in the research process have been analysed and advice on future improvements was given.
Light pollution assessment study based on AHP-CI-VCW model
Authors: Sun Weihao , Xiao Yutong
Published: December 2023

Light pollution has become increasingly serious in recent years. In order to better understand and mitigate the ecological and biological impacts of light pollution, a model was developed in this paper to measure the regional light pollution risk level. We developed the AHP-CI-VCW model. Based on the four main influencing factors of weather, reflection, air quality, and lighting, as well as the upper limit Ei for each indicator, we developed daytime and nighttime light pollution assessment models using hierarchical analysis and integrated index method, respectively. After that, we established the visual contrast weighting method, and assigned the scores of these two models to W1=1/7 and W2=6/7, respectively, and the two scores were summed to obtain the light pollution risk score of the region. We then selected protected areas such as the Grand Canyon of Colorado, rural Ashland, suburban Yonkers, and urban Washington to assess the light pollution risk level. We reviewed the local data and introduced them into the AHP-CI-VCW model and calculated scores of 1.117 for Colorado Grand Canyon, 1.975 for Ashland, 2.617 for Yonkers, and 2.815 for Washington, D.C. Using satellite light remote sensing maps, we validated the results and determined the light pollution risk levels for these four areas as none, low, moderate and high.

Published: December 2023

As the earliest inter-provincial metropolitan area started to be built in China, the Nanjing metropolitan area has become an important issue worthy of study in this region after 20 years of development. In order to quantify the characteristics of land use change and its driving factors, ArcGIS was used to calculate the land use transfer matrix and analyze the land use change in Nanjing metropolitan area for two time periods from 2000 to 2010 and 2010 to 2020, and the driving factors of land use change in the study area were explored by the method of principal component analysis. The results show that the Nanjing metropolitan area is dominated by arable land, forest land and water bodies, which account for more than 80% of the total area; the area of arable land decreases significantly and the area of construction land continues to increase during the study period, and the area of arable land transformed into construction land is the most numerous among the land use change types. The increase in population, socio-economic development and changes in climatic factors are the main driving factors for land use type conversion in the Nanjing metropolitan area. This study provides a theoretical basis for the sustainable and high-quality development of land resources and the coordinated development of human-land relations in the Nanjing metropolitan area.

Authors: Liu Linhai
Published: December 2023

Phenolic compounds constitute a broad category of extensively utilized chemical entities, the environmental residue of which has elicited substantial concerns regarding its deleterious impacts on natural ecology and human health. Over the past years, persulfate-based advanced oxidation technology (PS-AOPs), attributable to its effective degradation capacity for organic contaminants in aqueous environments, has garnered increasing interest among the scientific community. Relative to metal-based catalysts, their carbon-based counterparts possess distinct advantages such as non-toxicity, robust pH adaptability, appropriate pore volume, and extensive specific surface area, and have thus found considerable applications in activating PS for the removal of phenolic pollutants in water. This article provides a comprehensive review of recent research advancements concerning the use of carbon-based catalysts— including graphene, activated carbon, biochar, and metal-carbon composite materials — for the activation of PS aimed at phenolic pollutant removal. Additionally, it suggests potential trajectories for future investigations in this field.

Authors: Zheng Zhanxinyu , Chen Xingkang
Published: December 2023

Concentrations of carbon dioxide began to soar after the Industrial Revolution and are now a serious threat to the global climate, and predicting future carbon dioxide levels is essential to balance economic prosperity and sustainable development. In this paper, the gray GM (1, 1) model and the ARIMA model are established to predict future carbon dioxide concentrations. The gray GM (1, 1) model predicts that carbon dioxide concentration levels will reach 685 ppm by 2132, and ARIMA models predict that carbon dioxide concentration levels will reach 685 ppm by 2103. The goodness-of-fit of the gray GM (1, 1) model and the ARIMA model were 0.99989 and 0.99998, respectively, and the ARIMA model was more accurate than the prediction results of the grey prediction model.
Evaluation Model of Light Pollution Based on Analytic Hierarchy Process
Authors: Zeng Jianqiao
Published: December 2023

With the rapid development of the global economy, light pollution has become a new type of environmental pollution. In this paper, we propose a model to measure the degree of light pollution in a certain region (MDLP). In MDLP, we first consider the light demand of an area in relation to its population, GDP, and built-up area, so we apply the hierarchical analysis method (AHP) to calculate the weight of each factor and finally arrive at the light demand rate. Then We take into account environmental, social, amount of light factors when designing MDLP model. Finally, the results obtained for different indexes were graded and fitted with Bortle grades. This thesis provides theoretical support for study by sorting out the factors of the light pollution in city at night.

Authors: Zhou Xin , Li Rongcheng
Published: December 2023

In order to achieve the ambitious goals of "carbon peak" and "carbon neutrality" as soon as possible, it is necessary to study China's carbon emission level and emission reduction path. This research paper constructs a carbon audit evaluation model based on the "5E" theory using the entropy weight method and the red-green light scoring method, and empirically analyzes the national carbon audit scores from 2010 to 2022. The research results show that the carbon audit score of China is influenced by factors such as carbon emissions from economic contribution and improvement in low-carbon technology efficiency, and it shows an upward trend and will continue to grow rapidly in the future. The audit score demonstrates the effectiveness and direction of carbon governance in China. Based on the research results of the model and in combination with relevant policies and regulatory requirements, this paper proposes specific measures for green development and energy conservation and emission reduction from six aspects: industry characteristics and corporate behavior, energy structure, product and service quality, ecological civilization, environmental policies and regulations, and environmental publicity and raising public awareness.

Owing to the frequent presence of "white nights" recently, light pollution prevention and control measures are in great demand to resist the potential harm to humans and organisms. In this paper, we determined the light pollution risk evaluation index system from four dimensions to accurately measure light pollution risk levels in different types of areas. On this basis, the Revenue-Efficiency Index was introduced to measure sustainability. In response to the above analysis indicators, we proposed an advisable intervention strategy for glass curtain walls and confirmed its effectiveness through simulation. The indicator system was built by picking 40 countries with different levels of light radiation, and various indicators were chosen in multiple dimensions, thus the model is relatively reliable and universal.

This paper collected five states involved in the demand of water resources and hydropower resources, primarily hydrological conditions, lake Powell and lake mead. According to lake location, involves the basin and factors such as evaporation of lake Powell and mead lake water resources supply situation is analyzed, five states can get the final supply of water. Then, the water demand and daily water supply data of five states are used to solve the problem of the time to meet the fixed demand without additional water supply. The extra water supply is solved by considering the precipitation factor. Then, this paper solved the weight of different supply types in each state through Analytic Hierarchy Process to determine the water consumption priorities of five states and get the optimal allocation of different water types in each state. Finally, this paper ranks the water supply priority levels of five states and each industry in a state. The water supply scheme is given according to the priority levels.

To compare the differences in chemical composition correlation between high potassium glass and lead barium glass. Firstly, the Spearman correlation coefficient was used to observe whether there is a correlation between different chemical components. If there is a correlation, the degree of correlation has been indicated. At the same time, principal component analysis was used to reduce the dimensionality of 14 chemical composition indicators for high potassium glass and lead barium glass. The principal components corresponding to the characteristic values with a cumulative contribution rate of over 80% have been taken, and the meanings represented by these principal components have been explained. The specific differences in the correlation between the chemical composition content of different types of glass products have been studied, revealing the differences in the production processes of high potassium glass and lead barium glass.

Plant communities play a vital role in the ecological environment. In order to explore the relationship between drought adaptability and the number of species in the plant community, this paper discusses the survival ability of the plant community in a drought environment by constructing a neural network model, and studies and discusses the impact of the interspecific relationship of the plant community on survival. First, we found a positive correlation among the species in community Ⅱ through multiple regression model. Second, we quantify the concept of plant community into time-series data. Under the premise of considering the interaction between species, a BP neural network model based on gray prediction optimization was established to obtain the change law of species diversity index over time under different regular weather conditions. Finally, two concepts of species number and species type are introduced. The stability of the model was tested by changing the size of the species number and exchanging the dominant species among the communities.

In recent years, with the rapid development of big cities, light pollution is everywhere, which causes people to think. Balancing the benefits of artificial light and the negative effects of light pollution is an increasingly thorny issue. More and more environmentalists are calling for the cessation of extensive night lighting and nightlife to reduce the harm caused by light pollution. This paper establishes a risk level assessment model for light pollution and proposes three options for dealing with the phenomenon.Considering that the impact of light pollution involves all aspects of people's lives, six indicators, namely GDP, population density, percentage of arable land, energy consumption, percentage of population living under artificial brightness higher than natural brightness, and crime rate, were selected from economic, ecological, and social aspects to determine the risk level of light pollution. Hierarchical analysis and entropy weight were combined to obtain the combined weights. A linear weight scoring function r was constructed to determine the local light pollution level.In response to the formation factors of light pollution, three strategies are proposed to control light pollution in terms of luminaire types, lighting patterns and government management intervention and guidance. Among the types of lamps and lanterns, it is recommended to promote truncated lamps. In addition, reducing the commercial use of LED lighting is also a necessary solution. In terms of lighting patterns, two different lighting patterns are proposed, reducing the use of floodlighting and using less special lighting to minimize light pollution caused by improper lighting patterns. Finally, stand for the government to increase the management mode and optimize the city's lighting hours.

Light pollution is a serious and growing problem worldwide. How to develop a widely applicable light pollution indicator analysis model to help people monitor and mitigate light pollution is a question worthy of our consideration. This paper uses the TOPSIS integrated evaluation and decision method based on Entropy Weight Method (EWM) and Analytic Hierarchy Process (AHP) to identify indicators and establish a widely applicable LPI (Light Pollution Index) analyze Model for the global light pollution problem. Then this model is used for analyzing specific differentiated areas and develop optimal intervention strategies. In order to build an accurate model to assess global light pollution hazard levels, this paper have to take three key aspects into account: Light Trespass, Glare, Spill Light. For each aspect, six to eight sub-indicators were selected to measure different aspects of light pollution. This paper evaluated all indicators and by combining EWM and AHP, this paper obtained a Light Pollution Index Analyze Model. To verify the rationality and reliability of this model, this paper uses TOPSIS integrated evaluation and decision method based on EWM to predict and rank 20 countries worldwide in terms of light pollution risk index. The results show that comparing our data with monitoring data of Light Pollution Map, the two rankings show a high degree of agreement. Therefore, the model of this paper is reasonable and reliable. And the research of this paper can provide effective help to the research and monitoring of light pollution.
