Pollution Characteristics and Source Apportionment of Black Carbon Aerosols during Spring in Beijing
Authors: Lei Wenkai , Li Xingru , Yin Zhongyi , Zhang Lan , Zhao Wenji
Published: March 2024

Black carbon (BC) aerosols are important for absorbing aerosols, affecting global climate change and regional air quality, and potentially harming human health. From March to May 2023, we investigated black carbon aerosol levels and air pollution in Beijing. Employing methods such as linear regression, Potential Source Contribution Function (PSCF) and Concentration-Weighted Trajectory (CWT), we analyzed the characteristics and sources of black carbon aerosols in the region. Results indicate that the light absorption coefficients of BC and BrC decrease with increasing wavelength, with BrC accounting for less than 40% at 370 nm. Daily variations in BC and PM2.5 concentrations exhibit similar trends, peaking in March, and BC displays a distinct bimodal hourly concentration structure during this period. Aethalometer model results suggest that liquid fuel combustion contributes significantly to black carbon (1.08 ± 0.71 μg·m−3), surpassing the contribution from solid fuel combustion (0.31 ± 0.2 μg·m−3). Furthermore, the significant positive correlation between BC and CO suggests that BC emissions in Beijing predominantly result from liquid fuel combustion. Potential source area analysis indicates that air masses of spring in Beijing mainly originate from the northwest (40.93%), while potential source areas for BC are predominantly distributed in the Beijing–Tianjin–Hebei region, as well as parts of the Shandong, Shanxi and Henan provinces. Moreover, this study reveals that dust processes during spring in Beijing have a limited impact on black carbon concentrations. This study’s findings support controlling pollution in Beijing and improving regional air quality.

LTR-retrotransposons are transposable elements characterized by the presence of long terminal repeats (LTRs) directly flanking an internal coding region. They share genome organization and replication strategies with retroviruses. Steamer-like Element-1 (MchSLE-1) is an LTR-retrotransposon identified in the genome of the Chilean blue mussel Mytilus chilensis. MchSLE-1 is transcribed; however, whether its RNA is also translated and the mechanism underlying such translation remain to be elucidated. Here, we characterize the MchSLE-1 translation mechanism. We found that the MchSLE-1 5′ and 3′LTRs command transcription of sense and antisense RNAs, respectively. Using luciferase reporters commanded by the untranslated regions (UTRs) of MchSLE-1, we found that in vitro 5′UTR sense is unable to initiate translation, whereas the antisense 5′UTR initiates translation even when the eIF4E-eIF4G interaction was disrupted, suggesting the presence of an internal ribosomal entry site (IRES). The antisense 5′UTR IRES activity was tested using bicistronic reporters. The antisense 5′UTR has IRES activity only when the mRNA is transcribed in the nucleus, suggesting that nuclear RNA-binding proteins are required to modulate its activity. Indeed, heterogeneous nuclear ribonucleoprotein K (hnRNPK) was identified as an IRES trans-acting factor (ITAF) of the MchSLE-1 IRES. To our knowledge, this is the first report describing an IRES in an antisense mRNA derived from a mussel LTR-retrotransposon.

Published: March 2024

Aim: Angioid streaks (ASs) are a rare retinal condition and compromise visual acuity when complicated with choroidal neovascularization (CNV). They represent crack-like dehiscences at the level of the Bruch’s membrane. This objective narrative review aims to provide an overview of pathophysiology, current treatment modalities, and future perspectives on this condition. Materials and Methods: A literature search was performed using “PubMed”, “Web of Science”, “Scopus”, “ScienceDirect”, “Google Scholar”, “medRxiv”, and “bioRxiv.” Results: ASs may be idiopathic, but they are also associated with systemic conditions, such as pseudoxanthoma elasticum, hereditary hemoglobinopathies, or Paget’s disease. Currently, the main treatment is the use of anti-vascular endothelial growth factors (anti-VEGF) to treat secondary CNV, which is the major complication observed in this condition. If CNV is detected and treated promptly, patients with ASs have a good chance of maintaining functional vision. Other treatment modalities have been tried but have shown limited benefit and, therefore, have not managed to be more widely accepted. Conclusion: In summary, although there is no definitive cure yet, the use of anti-VEGF treatment for secondary CNV has provided the opportunity to maintain functional vision in individuals with AS, provided that CNV is detected and treated early.
An Improved One-Line Evolution Formulation for the Dynamic Shoreline Planforms of Embayed Beaches
Authors: Tao Hung-Cheng , Hsu Tai-Wen , Fan Chia-Ming
Published: March 2024

In this paper, an improved one-line evolution formulation is proposed and derived for the dynamic shoreline planforms of embayed beaches. Although embayed sandy beaches can perform several functions, serving as leisure spots and areas of coastal protection, shoreline advances and retreats occur continuously as a result of many natural forces, such as winds, waves, currents, tides, etc. The one-line evolution formulation for dynamic shoreline planforms based on the polar coordinate can be adopted to simulate high-planform-curvature shorelines and achieve better stability and simplicity in comparison with other description coordinates. While the polar coordinate and rectangular control volume are adopted to derive the one-line evolution formulation for dynamic shoreline planforms, the difference between the radial direction of the polar coordinate and the normal direction of the shoreline segment may result in inaccurate predictions of shoreline movements. In this study, a correction coefficient, which can adjust the influence of these two misaligned directions, is derived and included in the one-line evolution formulation, which is based on the polar coordinate. Thus, by considering the correction coefficient, an improved one-line evolution formulation for dynamic shoreline planforms of crenulate-shaped bays is proposed in this paper. Some numerical examples are provided to verify the merits of the proposed improved one-line evolution formulation. Moreover, the proposed numerical approach is applied to simulate the dynamic movements of the shoreline in Taitung—the southeastern part of Taiwan—and the effectiveness of the proposed formulation in solving realistic engineering applications is evidently verified.
Numerical Study of Pore Water Pressure in Frozen Soils during Moisture Migration

Published: March 2024

Frost heaving in soils is a primary cause of engineering failures in cold regions. Although extensive experimental and numerical research has focused on the deformation caused by frost heaving, there is a notable lack of numerical investigations into the critical underlying factor: pore water pressure. This study aimed to experimentally determine changes in soil water content over time at various depths during unidirectional freezing and to model this process using a coupled hydrothermal approach. The agreement between experimental water content outcomes and numerical predictions validates the numerical method’s applicability. Furthermore, by applying the Gibbs free energy equation, we derived a novel equation for calculating the pore water pressure in saturated frozen soil. Utilizing this equation, we developed a numerical model to simulate pore water pressure and water movement in frozen soil, accounting for scenarios with and without ice lens formation and quantifying unfrozen water migration from unfrozen to frozen zones over time. Our findings reveal that pore water pressure decreases as freezing depth increases, reaching near zero at the freezing front. Notably, the presence of an ice lens significantly amplifies pore water pressure—approximately tenfold—compared to scenarios without an ice lens, aligning with existing experimental data. The model also indicates that the cold-end temperature sets the maximum pore water pressure value in freezing soil, with superior performance to Konrad’s model at lower temperatures in the absence of ice lenses. Additionally, as freezing progresses, the rate of water flow from the unfrozen region to the freezing fringe exhibits a fluctuating decline. This study successfully establishes a numerical model for pore water pressure and water flow in frozen soil, confirms its validity through experimental comparison, and introduces an improved formula for pore water pressure calculation, offering a more accurate reflection of the real-world phenomena than previous formulations.

Published: March 2024

Reliable streamflow forecasting is a determining factor for water resource planning and flood control. To better understand the strengths and weaknesses of newly proposed methods in streamflow forecasting and facilitate comparisons of different research results, we test a simple, universal, and efficient benchmark method, namely, the naïve method, for short-term streamflow prediction. Using the naïve method, we assess the streamflow forecasting performance of the long short-term memory models trained with different objective functions, including mean squared error (MSE), root mean squared error (RMSE), Nash–Sutcliffe efficiency (NSE), Kling–Gupta efficiency (KGE), and mean absolute error (MAE). The experiments over 273 watersheds show that the naïve method attains good forecasting performance (NSE > 0.5) in 88%, 65%, and 52% of watersheds at lead times of 1 day, 2 days, and 3 days, respectively. Through benchmarking by the naïve method, we find that the LSTM models trained with squared-error-based objective functions, i.e., MSE, RMSE, NSE, and KGE, perform poorly in low flow forecasting. This is because they are more influenced by training samples with high flows than by those with low flows during the model training process. For comprehensive short-term streamflow modeling without special demand orientation, we recommend the application of MAE instead of a squared-error-based metric as the objective function. In addition, it is also feasible to perform logarithmic transformation on the streamflow data. This work underscores the critical importance of appropriately selecting the objective functions for model training/calibration, shedding light on how to effectively evaluate the performance of streamflow forecast models.
Development and Application of a New Exponential Model for Hydraulic Conductivity with Depth of Rock Mass
Authors: Dou Zhi , Huang Xin , Wan Weifeng , Zeng Feng , Wang Chaoqi
Published: March 2024

Hydraulic conductivity generally decreases with depth in the Earth’s crust. The hydraulic conductivity–depth relationship has been assessed through mathematical models, enabling predictions of hydraulic conductivity in depths beyond the reach of direct measurements. However, it is observed that beyond a certain depth, hydraulic conductivity tends to stabilize; this phenomenon cannot be effectively characterized by the previous models. Thus, these models may make inaccurate predictions at deeper depths. In this work, we introduce an innovative exponential model to effectively assess the conductivity–depth relationship, particularly addressing the stabilization at greater depths. This model, in comparison with an earlier power-like model, has been applied to a globally sourced dataset encompassing a range of lithologies and geological structures. Results reveal that the proposed exponential model outperforms the power-like model in correctly representing the stabilized conductivity, and it well captures the fast stabilization effect of multiple datasets. Further, the proposed model has been utilized to analyze three distinct groups of datasets, revealing how lithology, geological stabilization, and faults impact the conductivity–depth relationship. The hydraulic conductivity decays to the residual hydraulic conductivity in the order (fast to slow): metamorphic rocks, sandstones, igneous rock, mudstones. The mean hydraulic conductivity in stable regions is roughly an order of magnitude lower than unstable regions. The faults showcase a dual role in both promoting and inhibiting hydraulic conductivity. The new exponential model has been successfully applied to a dataset from a specific engineering site to make predictions, demonstrating its practical usage. In the future, this model may serve as a potential tool for groundwater management, geothermal energy collection, pollutant transport, and other engineering projects.

A prática predominantemente individual, curativa e de caráter liberal alicerçou, por muitos anos, a Odontologia, afastando-se de aspectos fundamentais de promoção da saúde e do atendimento humanizado. Nesta perspectiva, no cotidiano dos serviços em saúde bucal, ainda é possível perceber abordagens e ações fragmentadas, que prejudicam a prática de humanização e integralização do SUS e o processo de Educação Popular em Saúde. Dessa forma, a promoção da saúde evidenciada pela educação em saúde se torna uma ferramenta essencial, a qual promove a integração do ensino-serviço-comunidade. O objetivo do estudo é descrever um relato de experiência de graduandos em Odontologia da Universidade Federal de Juiz de Fora, desenvolvido por meio de ações de educação em saúde bucal para a população infantil e seus respectivos cuidadores assistidos pela Atenção Primária à Saúde do município de Juiz de Fora, com base nos preceitos de Educação Popular em Saúde, no período de março a setembro de 2022. Além disso, busca realizar uma reflexão crítica sobre a importância da integração ensino-serviço-comunidade. Para isso, foi elaborado um cronograma de visitas, seguido pelo planejamento das ações e o desenvolvimento das atividades educativas em saúde bucal, que incluíram estudos prévios do território, capacitação de funcionárias, além de palestras, atividades, jogos, teatros e cartilhas educativas sobre saúde bucal, utilizando-se de linguagem adequada de acordo com a população-alvo. Conclui-se que a integração ensino-serviço-comunidade representa uma estratégia relevante, ao articular a formação profissional e o serviço de atenção à saúde ofertado no SUS. Além disso, ações de educação em saúde em consonância com os ideais de humanização do SUS favorecem a autonomia dos indivíduos, de modo que devem ser estimuladas.

El problema de la libertad desde la propuesta spinoziana
Authors: Rivas Diaz Diego Alberto
Published: March 2024

En este artículo, se aborda, desde una óptica Spinoziana, el problema de la libertad. Spinoza rechaza la libertad como el libre albedrío. Sin embargo, considera que podemos tener agencia (libertad) en tanto, guiados por el conocimiento de las causas de nuestros afectos, actuemos en favor de nuestro conatus. Esta investigación está dividida en tres capítulos: En el primero, se reconstruye, someramente, la posición de Spinoza sobre el libre albedrío; en el segundo, se desarrolla su propuesta de agencia; finalmente, en el tercero, se busca reactualizar las consideraciones de Spinoza en torno a la discusión contemporánea sobre problema de la libertad.

Published: March 2024

This study analyzes the normative definition of the guarantees of political rights of citizens. A dialectical methodology of knowledge of law is used, and law is interpreted as an attribute of social management of society. A legal norm is understood as a process of necessity, the elements of which are the hypothesis, disposition and sanction of the norm in their organic connection. It is shown that the political rights and freedoms of a person and a citizen are established by the disposition of the legal norm, and their guarantees are determined by the sanction of the legal norm. The public legal character of political rights conditions their guarantee by legal acts of the court of administrative justice, as a type of justice. The study concludes that improving the normative definition of the guarantees of political rights is an urgent task for the management and legal regulation of political relations in modern society.

Published: March 2024

С увеличением продолжительности жизни наблюдают повышение числа пациентов с симптомами, обусловленными старением вестибулярного анализатора (ВА) — пресбивестибулопатией. В основе последней лежат дегенеративные процессы в различных отделах ВА — от полукружных каналов и отолитовых рецепторов до проводящих путей и вестибулярных ядер. При обследовании таких больных необходимо учитывать множественность поражения сенсорных систем у пожилых (нарушения равновесия, зрения, когнитивных функций). Признание пресбивестибулопатии частью многогранного процесса старения поможет разработать комплексные подходы к лечению пациентов, у которых всегда сохраняется риск ухудшения состояния. В этом обзоре обсуждается связь пресбивестибулопатии с нейродегенеративными заболеваниями, а также корреляция пресбивестибулопатии и нарушений равновесия, зрения, когнитивных и психологических расстройств.

With increasing life expectancy, there is an increase in the number of patients with symptoms caused by aging of the vestibular system — presbyvestibulopathy. Presbyvestibulopathy is based on degenerative processes in various parts of the vestibular analyzer — from the semicircular canals and otolithic receptors to the conduction tracts and vestibular nuclei. When examining such patients, it is necessary to take into account the multiplicity of damage to sensory systems in the elderly (impaired balance, vision, cognitive functions). Recognizing presbyvestibulopathy as part of the multifaceted aging process will help to develop comprehensive approaches to the treatment of patients who are always at risk for deterioration of the condition. In this review, we discuss the association of presbyvestibulopathy with neurodegenerative diseases, as well as the correlation between presbyvestibulopathy and balance, visual, cognitive, and psychological disorders.
An "Entirely Different Ballgame": The Marine Corps and NATO Exercises in Artic Norway, 1978-86
Authors: Donlon Brian
Published: March 2024

The U.S. Marine Corps consistently delivered substandard performance during training exercises in the Arctic in the late 1970s to mid-1980s. An examination of archival records, journal articles, student papers, and interviews with participants provides two explanations for the long period in which Marines were regarded as “rather poor winter warriors.” First, to overcome the challenges of Arctic operations, the Marine Corps had to make sustained, often slow, improvement in the three-step process of learning to survive, move, and fight in the Arctic. Second, the Corps’ culture simultaneously hamstrung and accelerated improvement in this Arctic trinity. Ultimately, the Corps’ slow road to success in the Arctic highlights the dependence of strategic change on proficiency at the lowest tactical levels.

Biopesticide Application Of Bacillus thuringiensis Local Isolate To Control Atherigona exigua Pest On Corn Plants
Authors: Salaki Christina Leta , Watung Jackson
Published: March 2024

Atherigona exigua is one of the main plant pest organisms (OPT) in maize. Among these pest control alternatives, the use of Bacillus thuringiensis bacteria has received attention because of its efficiency and low impact on natural enemies. This study aims: (1) to obtain the concentration of B. thuringiensis which has a high killing power on mortality of A. exigua larvae, (2) to determine the pathogenicity of B. thuringiensis to A. exigua. Testing for killing power and pathogenicity used the "Leaf dipped method" with five different concentrations of bacterial spore suspension, namely 1.5 x 103, 1.5 x104, 1.5 x 105, 1.5 x 106 and 1.5 x 107 spores/ml. . Parameters observed included attack symptoms, mortality percentage and time of death. Larval mortality was observed at 12, 24, 48 and 72 hours after application. Pathogenicity values ​​were expressed by LC50 and LT50 using probit analysis. The results showed that testing the killing power of 24 isolates, there were 10 isolates that were able to kill A. exigua larvae 50% after 72 hours at a concentration of 1.5 x 107 spores/ml, while the pathogenicity test based on the results of probit analysis showed that ITH isolates had a positive value. LC50 = 7.5 x 103 spores/ml. Time of death (LT50) = 19.5 hours.

The Effect Of Sago Flour And Red Bean Substitution On Crysty Level and Protein Levels Of Dry Pia.
Authors: Assa Jan Rudolf , Mandey Lucy C. , Lagarinda Tasya V.
Published: March 2024

Pia is a popular snack food, the main raw material is wheat flour which is still an imported material in the form of wheat seeds. Imports of Indonesian wheat seeds tend to increase from 2010 to 2020. To reduce the use of wheat flour, especially in dry pia, it is necessary to substitute sago flour, the addition of sago flour is also related to the level of crispness. The problem is that the protein content of sago flour is low, so it is necessary to substitute red bean flour which has a high protein content. This study substituted sago flour and red bean flour with the following proportions: Wheat Flour 70%: Sago Flour 10%: Red Bean Flour 20% (T0);  Wheat Flour 60%: Sago Flour 20%: Red Bean Flour 20% (T1);  Wheat Flour 50%: Sago Flour 30%: Red Bean Flour 20% (T2);  Wheat Flour 40%: Sago Flour 40%: Red Bean Flour 20% (T3). The results showed that protein content decreased with an increasing proportion of sago flour and dry pia crispness increased with the increasing proportion of sago flour.

Abstrak

Pia merupakan makanan ringan yang digemari masyarakat, bahan baku utamanya adalah tepung terigu yang saat ini masih merupakan bahan import dalam bentuk biji gandum. Import biji gandum Indonesia cenderung meningkat dari tahun 2010 sampai 2020. Untuk mengurangi penggunaan tepung terigu khususnya pada pia kering perlu substitusi tepung sagu, penambahan tepung sagu juga berhubungan dengan tingkat kerenyahan. Masalahnya kadar protein tepung sagu rendah sehingga perlu juga substitusi tepung kacang merah yang kadar proteinnya tinggi. Penelitian ini melakukan substitusi tepung sagu dan kacang merah dengan proporsi: Tepung Terigu 70% : Tepung Sagu 10% : Tepung Kacang Merah 20% (T0); Tepung Terigu 60% : Tepung Sagu 20% : Tepung Kacang Merah 20% (T1); Tepung Terigu 50% : Tepung Sagu 30% : Tepung Kacang Merah 20% (T2); Tepung Terigu 40% : Tepung Sagu 40% : Tepung Kacang Merah 20% (T3). Hasil penelitian menujukkan kadar protein menurun dengan meningkatnya proporsi tepung sagu dan tingkat kerenyahan pia kering meningkat dengan bertambahnya proporsi tepung sagu.
