Symmetry and Asymmetry of Chaotic Motion in a Crank Arm and Connecting Rod Due to the Movement of the Follower
Authors: Yousuf Louay S.
Published: December 2023

The symmetry and asymmetry of chaotic motion in the planar mechanism is investigated for a crank arm and connecting rod due to the motion of a flat-faced follower. The level of chaos is investigated using the conception of the Lyapunov exponent parameter and phase-plane diagram at different cam speeds with and without the use of coefficients of restitution. Moreover, the fast Fourier transform (FFT) of power spectrum analysis technique is used based on SNR factor values at different cam speeds and different coefficients of restitution. The wave forms and histograms of nonlinear responses are analyzed using the SolidWorks program for the crank arm, connecting rod, and flat-faced follower. There is a clearance between the flat-faced follower and its guides while the oscillation motion of the crank arm and connecting rod is described as the motion of a double pendulum. The level of chaos is increased with increases in the cam speeds and coefficients of restitution.

Authors: Zhuang Xinyu , Xie Yuzhou
Published: December 2023

Disasters caused by climate change are continuing around the world. Densely populated urban areas have been pushed to the forefront of global climate change, and ecological security has gradually become the focus of global attention. Whether it is predictable natural disasters, or it is long-term global warming, or any unexpected events, exploring green development that coexists with them, green urban environmental strategies will play an important role in urban development. We analyzed data from 31 sample cities in China, accurately quantified indicators through qualitative and quantitative analysis, and then explored the development status and related indicator systems of green cities in China by “Driving Force–State–Response” model. The results reveal that (1) economic factors are the fundamental and decisive factors for the development of green cities. The higher the level of economic development, the stronger the ability of urban development; we also revealed the indicators that are significantly correlated with the level of green city construction and clarified the important factors of green cities; (2) technological factors are crucial for the construction of green cities. Only with continuous improvement at the technological level do green industries have the driving force for sustainable development, and traditional high-energy consuming and high-pollution industries can be continuously eliminated so as to promote the construction of green cities. (3) Based on the correlation analysis between each indicator and comprehensive scores, this study also pointed out that there is a significant gap in the level of green city construction among different regions in China.

Objective: To investigate the role of miR-212-5p-targeted ARAF during the apoptosis of rat alveolar macrophages induced by cowshed PM2.5. Methods: miRNA and related target genes and pathways were predicted using the KEGG, TargetScan, and other prediction websites. NR8383 macrophages were treated with cowshed PM2.5 to establish an in vitro lung injury model in rats; meanwhile, for the assessment of cell viability, apoptosis, intracellular calcium ions, and mitochondrial membrane potential in NR8383 cells, RT-qPCR was used to detect the expression of miR-212-5p and the target gene ARAF. Results: The bioinformatic analyses showed that miR-212-5p and ARAF were involved in PM2.5-associated cellular damage. Exposure to different concentrations (0 μg/mL, 60 μg/mL, 180 μg/mL, 300 μg/mL) with different durations (0 h, 12 h, 24 h, 48 h) of cowshed PM2.5 resulted in apoptosis, increased intracellular calcium ions, and decreased mitochondrial membrane potential. The miR-212-5p mimic group showed an up-regulation of Bax and cleaved Caspase 3 expression but decreased Bcl2 expression compared to the NC group, and overexpression of ARAF up-regulated the expression of p-MEK1/2 and p-ERK1/2 and simultaneously reversed the above phenomena. Conclusions: miR-212-5p targets ARAF to affect the cowshed PM2.5-induced apoptosis through the MEK/ERK signaling pathway, providing a potential target for relevant farming industry and pathology studies.
Recent Advances in Black Phosphorous-Based Photocatalysts for Degradation of Emerging Contaminants
Authors: Zhang Zhaocheng , He Dongyang , Zhang Kangning , Yang Hao , Zhao Siyu , Qu Jiao
Published: December 2023

The recalcitrant nature of emerging contaminants (ECs) in aquatic environments necessitates the development of effective strategies for their remediation, given the considerable impacts they pose on both human health and the delicate balance of the ecosystem. Semiconductor-based photocatalytic technology is recognized for its dual benefits in effectively addressing both ECs and energy-related challenges simultaneously. Among the plethora of photocatalysts, black phosphorus (BP) stands as a promising nonmetallic candidate, offering a host of advantages including its tunable direct band gap, broad-spectrum light absorption capabilities, and exceptional charge mobility. Nevertheless, pristine BP frequently underperforms, primarily due to issues related to its limited ambient stability and the rapid recombination of photogenerated electron–hole pairs. To overcome these challenges, substantial research efforts have been devoted to the creation of BP-based photocatalysts in recent years. However, there is a noticeable absence of reviews regarding the advancement of BP-based materials for the degradation of ECs in aqueous solutions. Therefore, to fill this gap, a comprehensive review is undertaken. In this review, we first present an in-depth examination of the fabrication processes for bulk BP and BP nanosheets (BPNS). The review conducts a thorough analysis and comparison of the merits and limitations inherent in each method, thereby delineating the most auspicious avenues for future research. Then, in line with the pathways followed by photogenerated electron–hole pairs at the interface, BP-based photocatalysts are systematically categorized into heterojunctions (Type I, Type II, Z-scheme, and S-scheme) and hybrids, and their photocatalytic performances against various ECs and the corresponding degradation mechanisms are comprehensively summarized. Finally, this review presents personal insights into the prospective avenues for advancing the field of BP-based photocatalysts for ECs remediation.
Overview of Nucleocapsid-Targeting Vaccines against COVID-19
Authors: Rak Alexandra , Isakova-Sivak Irina , Rudenko Larisa
Published: December 2023

The new SARS-CoV-2 coronavirus, which emerged in late 2019, is a highly variable causative agent of COVID-19, a contagious respiratory disease with potentially severe complications. Vaccination is considered the most effective measure to prevent the spread and complications of this infection. Spike (S) protein-based vaccines were very successful in preventing COVID-19 caused by the ancestral SARS-CoV-2 strain; however, their efficacy was significantly reduced when coronavirus variants antigenically different from the original strain emerged in circulation. This is due to the high variability of this major viral antigen caused by escape from the immunity caused by the infection or vaccination with spike-targeting vaccines. The nucleocapsid protein (N) is a much more conserved SARS-CoV-2 antigen than the spike protein and has therefore attracted the attention of scientists as a promising target for broad-spectrum vaccine development. Here, we summarized the current data on various N-based COVID-19 vaccines that have been tested in animal challenge models or clinical trials. Despite the high conservatism of the N protein, escape mutations gradually occurring in the N sequence can affect its protective properties. During the three years of the pandemic, at least 12 mutations have arisen in the N sequence, affecting more than 40 known immunogenic T-cell epitopes, so the antigenicity of the N protein of recent SARS-CoV-2 variants may be altered. This fact should be taken into account as a limitation in the development of cross-reactive vaccines based on N-protein.

Digital financial assets: definition and classification
Authors: Havva Vitalii , Haponiuk Mykola
Published: December 2023

Introduction. The digitization of the economy began back in the 50s and 60s of the 20th century, but the term "digital assets" began to be actively used by financial market participants and scientists only after 2008, the impetus for which was the appearance of the so-called distributed ledger technology and the creation of the first cryptocurrency - bitcoin. However, today there is no comprehensive definition of the concept of "digital financial asset" that would fully reveal the essence of this term. Moreover, there is sometimes terminological uncertainty and confusion regarding the terms "cryptocurrency", "digital assets", "cryptoassets" and "virtual assets", which can lead to gaps in their regulation. Therefore, clarification of the definition and types of digital financial assets is relevant.
The purpose of the article is to clarify the definition of digital financial assets by revealing the essence and characteristics of digital assets and financial assets, as well as justify the classification of certain types of digital assets as financial assets.
The research method (methodology) is based on the systematic use of methods of analysis, synthesis, generalization and comparison, using a complex approach to studying the problem.
The results. It was determined that such a new type of assets as digital financial assets arose at the stage of digitalization of the economy associated with the emergence of distributed ledger technology. It is clarified that according to IAS, digital financial assets can be represented by instruments such as cash, equity instruments or contractual rights. It was determined that the concept of "digital assets" is identical to the concept of "electronic assets" or "virtual assets" in the domestic legal framework. The classification of types of digital assets according to various criteria is generalized. It is substantiated that digital financial assets include such groups of digital assets, which are represented by payment tokens and tokens in securities, and utilitarian tokens are not financial assets.

Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan pupuk organik dan mikoriza terhadap kadar klorofil dan antosianin pada daun ubi jalar ungu (Ipomoea batatas var. Ayamurasaki) yang ditanam di lahan marjinal. Penelitian ini menggunakan desain faktorial dalam Rancangan Acak Kelompok dengan tiga ulangan untuk setiap perlakuan. Pengukuran kandungan klorofil a, b, dan total, serta antosianin dilakukan menggunakan metode spektrofotometri. Analisis data dilakukan dengan uji Analisis Varian (ANOVA) dua arah pada tingkat signifikansi α = 5%. Hasil analisis menunjukkan bahwa perlakuan tidak memiliki pengaruh signifikan terhadap kandungan klorofil a dan klorofil b. Namun, penggunaan mikoriza dan pupuk organik menunjukkan perbedaan signifikan dalam kandungan klorofil total. Perlakuan dengan pemberian mikoriza 10 g dan pupuk organik 50 gr per lubang tanam (M0P0) memberikan kandungan klorofil total tertinggi. Meskipun tidak ada perbedaan signifikan dalam kadar antosianin antara perlakuan yang berbeda, penggunaan mikoriza 10 g per lubang tanam dan pupuk organik cenderung meningkatkan kadar antosianin. Hasil ini menunjukkan bahwa kombinasi penggunaan mikoriza dan pupuk organik dengan dosis yang tepat dapat meningkatkan kadar antosianin pada daun ubi jalar ungu.

Published: December 2023

Sexing atau pemisahan spermatozoa adalah proses pemisahan spermatozoa yang membawa sifat kelamin jantan dan betina. Infertilitas merupakan satu kondisi dimana pasangan yang aktif secara seksual tanpa melakukan kontrasepsi tidak mampu mendapat kehamilan dalam kurun waktu selama 1 tahun. Sekitar 50-80 juta pasang suami istri di dunia (1 dari 7 pasutri) yang terkena masalah infertil dan pada setiap tahun muncul sekitar 2 juta pasangan suami istri infertil. Di Indonesia diperkirakan ada 4 juta sekian pasangan suami istri yang mengalami infertil atau ketidaksuburan. Solusi yang dapat dilakukan untuk mencegah dan menghindari kerusakan membran pada spermatozoa saat pemisahan spermatozoa adalah dengan menggunakan metode sentrifugasi dengan penambahan kuning telur. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis integritas membran spermatozoa pada proses sexing sebelum dan sesudah pemberian kuning telur. Metode yang digunakan adalah Rancangan Acak Lengkap dengan tiga perlakuan, yaitu kontrol, sentrifugasi, sentrifugasi + kuning telur.

Pain is a health problem phenomenon that most often brings patients to see a doctor. Pain intensity is the most often domain which assessed in clinical and research settings. Loeser suggests that four elements need to be considered when evaluating patients with pain. Based on the biopsychosocial approach and the concept of pain from Loeser, a pain assessment was made and called "Alternative Method of Quantitative Pain Assessment (MAPKN)". This study was conducted on 415 pain patients consisting of 163 nociceptive pain, 119 mixed pain, and 133 neuropathic pain. In the nociceptive pain group, MAPKN showed sensitivity 92.59%, specificity 96.43%, AUC 0,959 and a p value <0.001. In the mixed pain group, MAPKN showed sensitivity 98.17%, specificity 80.00%, AUC 0,836 and a p -value of 0.001. In the neuropathic pain group, MAPKN showed sensitivity 92.06%, specificity of 85.71%, AUC 0,951 and a p<0.001. The AUC value of 0.959 (96%) indicates that the diagnostic value of the MAPKN score in assessing pain intensity in the nociceptive pain group is excellent (>90%-100%). AUC value of 0.836 (83%) indicates that the diagnostic value of the MAPKN score in assessing pain intensity in the mixed pain group is good (> 80%-90%). The AUC value of 0.951 (95%) indicates that the diagnostic value of the MAPKN score in assessing pain intensity in the neuropathic pain group is excellent (>90%-100%). This is in accordance with research conducted by Eka Pranata 2004 that MAPKN has strong discriminant validity in assessing pain intensity. MAPKN is valid and has excellent diagnostic value in assessing nociceptive and neuropathic pain intensity, MAPKN is valid and has good diagnostic value in assessing mixed pain intensity.
Heavy metal contamination in the soil and Taal Lake Post-Taal Volcano eruption
Authors: Banta Genevee , Salibay Cristina
Published: December 2023

Volcanic eruption can be a source of heavy metal contamination in the environment and such contamination may cause certain risks to the environment and to those who are exposed to the volcanic contents. This study aimed to assess the agricultural soil for heavy metal contamination after the 2020 Taal volcano eruption. The agricultural soil samples were collected from Cuenca and Talisay, Batangas and Tagaytay City, Cavite and were submitted to a laboratory for arsenic, cadmium and mercury detection and quantification. The detected metal concentrations were compared to the standard values of the Department of Environmental and Natural Resources for arsenic and United States Environmental Protection Agency for cadmium and mercury for soil samples while for the water samples, the standard values of Department of Environment and Natural sources were used. The soil from Talisay, Batangas had two-fold arsenic increase while the samples from Tagaytay City, Cavite had one-fold elevation. Cadmium and mercury in the soil and water were within the acceptable level in the three municipalities. The arsenic contamination of the soil post-volcanic eruption was probably due to the direction of the wind during the eruption, the amount of ashfall and groundwater contamination. Heavy metal contamination can be detected years after the eruption.

The purpose of this research is to formulate a C-RAN(Cloud-Radio Access Network) model based on a fair network combined with an isoelastic utility function and a modified cobb-douglas utility function and then optimize the consumer problem on bandwidth consumption by dividing the financing scheme into three, namely flat-fee, usage-based, and two-part tariff. This research uses traffic data containing inbound and outbound data with two split time which are in off-peak and on-peak hours. The data is obtained through one of the local server in Palembang. Previous research informed that the C-RAN model get optimal benefit if Internet Service Provider (ISP) applies it. The improvement of the model is to be conducted using two utility function to seek for improved solutions. The new proposed model has best solution that has been improved using an isoelastic utility function of flat-fee financing type with an objective value obtained of 1.83333 with 17 iterations. It can be concluded that new designed model can achieve better results rather than old version involving C-RAN model
