Comparison of Critical Shear Stress of Rill Erosion Estimated from Two Methods
Authors: Geng Ren , Jin Qiu , Lei Shaohua , Liu Hongyuan , Lu Bin , Xie Meixiang
Published: June 2022

Various disputes exist regarding the critical shear stress (τc) of rill erosion determined by linear regression. Alternatively, some researchers have attempted to measure critical shear stress (τo) of rill erosion by observing the start of soil particle detachment and showed promising results. However, few studies have been conducted to evaluate the reliability of the method determining τo. Thus, this study was conducted to identify the reliability of the method determining τo by comparing the values of τc and τo and their relationships with rill erodibility (Kr) and influencing factors, using 360 disturbed soil samples (standing for the freshly tilled condition) from six sampling sites along a 330 km transect in the Loess Plateau. Results indicated that the mean τc was 1.90 times greater than that of τo. No significant relationship was found between τc and Kr. An inverse changing trend between Kr and τo was observed from Yijun to Zizhou, while both Kr and τo exhibited increasing trends from Zizhou to Yulin. The τo of six sampling sites all demonstrated increasing trends with slope gradient (S), which contradicted the statement of the WEPP model that τc was independent of S. The relationships between τc and the measured soil properties were poor, whereas the τo increased exponentially with soil organic matter. Generally, τo did not present significantly better results than τc; the reliability of τo also showed some uncertainties, such as the subjective judgment of the beginning detachment of soil particles. This result has great importance for deepening our understanding of the rill erosion mechanism.

To investigate the interaction and erosion mechanisms between an ultrahigh-pressure water jet and the surface of Grade A marine steel, this study used the ANSYS FLUENT software to simulate the hydrodynamic characteristics of an ultrahigh-pressure water jet. To erode the Grade A marine steel, a water jet with ultrahigh-pressure (200 MPa, 40 L/min) was used. An ASMC2-4 resistance strain gauge collected the dynamic strain signal at the back of the sample during jet impingement, and the simulation results were compared to experimental results. A scanning electron microscope (SEM), X-ray diffractometer (XRD), energy dispersive spectrometer (EDS), and other equipment were used to observe and analyze the phase before impact and the material surface morphology and element distribution after impact. The results reveal that as the wall shear stress increased with the target distance, the energy loss of the jet could be reduced by changing the jet incidence angle, and the peak value of the wall shear stress increased. Under the pressure of 200 MPa, the average microstrain at the back side of the impact center area of the Grade A marine steel was 180 × 10−6, and the microstrain amplitude was 35 × 10−6–50 × 10−6. The impact force of the water jet on the Grade A marine steel produced alternating stress with cyclic fluctuation. The experimental results are consistent with the simulation results. Under the alternating jet stress action, fatigue failure and cavitation failure occurred on the sample surface, which was characterized by a spalling pit, layer erosion, and cavitation hole morphology. The surface stripping model of the Grade A marine steel under an ultrahigh-pressure water jet was established, and the interaction mechanism and erosion mechanism between the ultrahigh-pressure water jet and the surface of the Grade A marine steel were elucidated.

Published: June 2022

In river management, it is important to obtain ice velocity quickly and accurately during ice flood periods. However, traditional ice velocity monitoring methods require buoys, which are costly and inefficient to distribute. It was found that UAV remote sensing images combined with machine vision technology yielded obvious practical advantages in ice velocity monitoring. Current research has mainly monitored sea ice velocity through GPS or satellite remote sensing technology, with few reports available on river ice velocity monitoring. Moreover, traditional river ice velocity monitoring methods are subjective. To solve the problems of existing time-consuming and inaccurate ice velocity monitoring methods, a new ice velocity extraction method based on UAV remote sensing technology is proposed in this article. In this study, the Mohe River section in Heilongjiang Province was chosen as the research area. High-resolution orthoimages were obtained with a UAV during the ice flood period, and feature points in drift ice images were then extracted with the scale-invariant feature transform (SIFT) algorithm. Moreover, the extracted feature points were matched with the brute force (BF) algorithm. According to optimization results obtained with the random sample consensus (RANSAC) algorithm, the motion trajectories of these feature points were tracked, and an ice displacement rate field was finally established. The results indicated that the average ice velocities in the research area reached 2.00 and 0.74 m/s, and the maximum ice velocities on the right side of the river center were 2.65 and 1.04 m/s at 16:00 on 25 April 2021 and 8:00 on 26 April 2021, respectively. The ice velocity decreased from the river center toward the river banks. The proposed ice velocity monitoring technique and reported data in this study could provide an effective reference for the prediction of ice flood disasters.
A Simplified Method for Leakage Estimation of Clay Core Dams with Different Groundwater Levels
Authors: Yang Chao , Shen Zhenzhong , Xu Liqun , Shen Hongjie
Published: June 2022

Clay core dams are widely applied in reservoir construction, regulating water resource and provide electric power. Leakage is a common problem in reservoir construction, and the leakage amount, which not only affects the economic benefits of the project, but also relates to the safety of the dam body, is difficult to estimate. According to Darcy’s law and stable seepage theory, an analytical method can be proposed to calculate the leakage of the clay core dam to gain the seepage flux in a short time. By making some reasonable assumptions, we propose formulae for seepage calculation in different conditions of the position of the groundwater levels, below or above the reservoir bottom. Both sets of formulae contain two parts of leakage calculation, i.e., leakage from the reservoir bottom and leakage from the dam body. By using the proposed analytical method, the leakage of clay core dams can be estimated considering the influence of the groundwater level. To prove the rationality of the analytical method, a simple numerical model can be established using Geo-studio 2020 to calculate the seepage flux of the clay core dam, where relative errors between numerical solutions and analytical solutions are less than 10%. To verify the feasibility in engineering applications, the proposed method was applied to calculate the seepage of a clay core dam in Sichuan, China, which was also calculated using numerical methods by establishing a three-dimensional model. The results show the rationality of the analytical method, which can strike a balance between precision and efficiency.

Published: June 2022

High temperatures and droughts following winter dormancy can negatively affect seedling growth and mortality. An open-field experiment was conducted to study the growth and mortality of Larix kaempferi seedlings in response to spring warming and drought treatments and to determine whether seedlings could regain their growth capability once the treatments were discontinued. In May 2020, 1-year-old seedlings were exposed to four treatments: control, warming-only, drought-only, and the combined warming and drought. Drought treatment reduced the seedling height and root collar diameter and increased the mortality rate. The combined warming and drought treatments had the highest mortality rates, followed by the drought, control, and warming treatments. However, after the cessation of the treatments, the combined warming and drought treatments increased seedling height, root collar diameter, and individual seedling biomass because the high mortality rate relaxed competition among seedlings. This suggests that the effects of low competition on the surviving seedlings may mitigate the negative effects of warming and drought on seedling growth. Our study demonstrates that despite the high mortality and decreased growth during the treatment period, seedlings subjected to combined high temperature and drought stress showed short-term high levels of growth compared to seedlings subjected to a single stress.

THE FOOD SECURITY DOCTRINE FIASCO
Authors: Gumerov Rustam R.
Published: June 2022

The article is devoted to topical, including little-studied aspects of the implementation of the Food Security Doctrine of the Russian Federation. The price "shock" in the consumer market at the end of 2020 provoked a situation of food insecurity and confirmed the need to rethink the priorities and goals of the Doctrine and focus on ensuring access to adequate nutrition for all groups and strata of the Russian population. Along with methodological questions regarding the criteria, goals and objectives of ensuring food security laid down in the Doctrine, the article raises the problems of practical implementation of this document and concludes that there are no relevant tools and levers of economic policy in the subject area. The article concludes with a concise summary of practical recommendations for making changes and additions to the Doctrine, as well as to strategic planning documents and regulations that ensure its implementation. The external reaction to the first results of the special operation in Ukraine confirms the need to strengthen food sovereignty in practice, not limited to import substitution. Further special studies in this direction are needed with the fixation of their results in the updated version of the Food Security Doctrine of the Russian Federation for the medium term.

El garante y su responsabilidad penal en el delito de violación sexual
Authors: Chinchay abad Laura stefany
Published: June 2022

El derecho penal reconoce los delitos por omisión impropia, como hechos ilícitos donde un sujeto denominado garante no reacciona ante un inminente peligro o lesión a un bien jurídico, siendo así que, mediante su omisión coopera a la lesión al bien jurídico. En consecuencia, se genera una responsabilidad penal; sin embargo, en el ordenamiento penal peruano pocas veces se logra atribuir responsabilidad penal al progenitor indolente, que con su omisión contribuyen a la ejecución de la violación sexual de su menor hijo; debido a la falta de criterios para justificar y argumentar esta responsabilidad, pues, los entes jurisdiccionales consideran a dicho comportamiento omisivo como un comportamiento social y moralmente reprochable más no un hecho ilícito. Por ello, los fundamentos para atribuir responsabilidad penal al garante, refuerzan la aplicación de la teoría de la omisión impropia en los delitos de violación sexual.

Expansive clay soils are categorized as poor as subgrades because of their low capacity for bearing soil. Therefore,  it needed to stabilize with added lime and fly ash materials. This study aimed to determine the effect of adding lime and fly ash on the bearing capacity of expansive clay in the form of shear stress and CBR values. The research method used is observation, namely testing of physical and mechanical properties in the laboratory. The tests were carried out on the original soil, and soil was stabilized using 5% lime, and the fly ash content was 10%, 20%, 30%, 40%, and 50%. The biggest change in the value of the CBR test occurred in the CBR value that was not submerged after seven days of curing on a variation of a mixture of 5% lime (fixed) and 50% fly ash, which was 11.74% of the original soil CBR value of 1.39%. The largest increase in soil bearing capacity (qu) and undrained soil cohesion (cu) was obtained in the composition of the original soil mixture, 5% lime and 50% fly ash, namely 0.368 kg/cm2 and 0.184 kg/cm2. The results showed that the stabilization of expansive clay using lime and fly ash increased the bearing capacity of the soil.

Unconventional columns are very familiar in modern building construction because they impact the room's efficiency. Meanwhile, conventional columns affect the lack of efficiency in the room's functions. The performance analysis of the two types of columns used pushover analysis of the capacity spectrum method using ETABS v 16.1.0 software. The performance level results of the two types of columns in low-rise buildings are the same, which is Immediate Occupancy. The most significant maximum shearing force is at a low-rise building with an unconventional column with a maximum displacement on the east side of 160,00 mm. The smallest is a low-rise building with a conventional column in the east direction with maximum displacement on the Nort side of 90,11 mm. Thus, comparing the performance of the two types of columns can be concluded that conventional columns are stronger than unconventional columns.

THE IMPORTANCE OF URBAN DESING ACTIVITIES IN TAKING A HOLITICAL APPROACH TO URBAN PLANNING: “BEYKOZ-KARLITEPE URBAN DESIGN GUIDE EXAMPLE”
Authors: ELMAS Eyüp Salih
Published: June 2022

Urbans are the multifunctional living areas with high density which contains natural and unnatural and where agricultural activities are hardly any. Physical planning dimension of the vision created for the urbans with strategy plans and environment plans are named zone planning. Acorrding to the current zoning plan construction legislation, it is considered sufficient to make master and implementation zoning plans by city planners. However, the climate change and its consequences whose negative effects have been felt increasingly in recent years and loss of life and property caused by wrong settlement selection in natural disasters point out clearly the necessity of holistic approach to the urban planning. Thanks to detailed and holistic considering many factors such as natural and artificial thresholds, climatic characteristics, vegetation, geological structure, socio-economic values in the process of the developing of implemention zoning plan, it can be constructed sustainable, viable and publicly supported urban areas.

When the urban design examples in developed countries are examined, it is determined that the holistic approach to planning is dominant. But, if native examples are analysed, it is seen that the urban design applications remains at the level of improving the building facades and signboard organization, except some urban desings in the rural areas.

It should be aimed to ensure that acknowledgment by the stakeholders that the urban design work is specific to the urban area and it is a product of a detailed analysis process and to practice across the country. For this reason, it is the most important aim of this study to show that urban design studies constitute an important source and basis for gaining a holistic approach to urban planning. It is thought that the study will be an example of the necessity of a holistic approach to preparation process of the implementation development plan and will provide an insight to the elimination of the deficiency in the current plannig legislation and contribute to the literature.

Vivemos em uma era na qual uma informação pode ser vista e compartilhada em uma velocidade assombrosa – e ainda de forma gratuita e segura. Nessa seara, a tecnologia pode ser uma aliada para a educação. Levando em consideração que muitos discentes de um dos campi do interior do estado do Instituto Federal de Educação, Ciência e Tecnologia do Ceará costumam menosprezar a disciplina de Língua Inglesa4, utilizamos dois Recursos Educacionais Digitais (RED) para propor atividades com traços de gamificação no ambiente de sala de aula remota, para promover engajamento e maior interesse nas aulas da referente língua estrangeira, sob a ótica de Freire (2009), Ramos (2009) e Kenski (2003), em uma tentativa de superar os impasses decorrentes do enfrentamento do Coronavírus (SARS-COV-2/COVID-19). Destarte, o presente estudo analisou a percepção dos estudantes sobre o impacto das ferramentas Kahoot! e Quizizz no ensino e na aprendizagem das disciplinas de Inglês para Fins Específicos. Para conduzir esse estudo de caso com traços exploratórios, inicialmente, propusemos atividades com esses RED no referido componente curricular, na modalidade remota. Posteriormente, na finalização do semestre letivo, foi enviado um formulário on-line para que os alunos regularmente matriculados que utilizaramesses recursos expressassem suas impressões. Obtivemos respostas de vinte dois (22) educandos reconhecendo a importância dos dois RED para a melhora do aprendizado, o reforço dos conhecimentos adquiridos via videoaulas e a revisão de questões, deixando as aulas mais dinâmicas. Portanto, a prática pedagógica adotada parece ter sido eficaz; contudo, outros estudos com grupos maiores precisam ser conduzidos.

Published: June 2022

O protagonismo juvenil materializado com práticas de voluntariado educativo (SBERGA, 2002), expande a perspectiva de humanidade integral e possibilita caminhos para uma educação mais crítica. No contexto escolar, nota-se que discentes demonstram interesse por diferentes áreas do conhecimento, mas apresentam dificuldade em unir teoria e prática. Portanto, este trabalho justificou-se ao proporcionar um espaço de reflexão e amadurecimento sobre a realidade em que o estudante está inserido e a aplicabilidade do conhecimento sistemático de forma crítica e engajada socialmente em práticas cotidianas. Neste sentido, o Núcleo de Voluntariado Educativo (NuVE), em atividade no IFMS campus Campo Grande desde 2018, atuou durante o ciclo de iniciação científica CNPq/ICJ 2020-2021(Edital 019/2020 Propi-IFMS), sob a perspectiva do letramento crítico, buscando potencializar iniciativas estudantis e momentos de reflexão crítico-social (MORGAN; MONTE MOR, 2014; MONTE MOR, 2013).Como resultado, observou-se um engajamento por parte dos estudantes na promoção do desenvolvimento da cidadania, agência e inclusão por meio do exercício de projetos de intervenção baseados numa perspectiva educacional crítica e científica focadas em necessidades da comunidade (mobilidade urbana, diversidade linguística, arte e cultura e sustentabilidade). Diretamente aos estudantes pesquisadores, o projeto mostrou-se como uma experiência formativa, que integra saberes escolares, competências e habilidades às práticas sociais.

Abstract: Purpose: This paper investigated the effect of the tax burden on the inflow of FDI into the continent. The study employed a panel data set of 48 SSA countries covering a period of 2009 to 2018. Research methodology: In other to account for the endogeneity problems associated with most financial data, we employed a dynamic panel two-step-system-GMM. Results: The result indicates that tax burden is a negative determinant of the inflow of FDI. In other words, multinational corporations attach a significant premium to countries with low tax burdens than those with a high tax burden. Similarly, an increase in the mobility of labour is a negative determinant of the inflow of FDI into the continent. All the economic and financial freedom indices included in the model have a positive and significant influence on the inflow of FDI into the continent. A sustainable tax policy that will lessen the tax burden on foreign investors should be formulated to enhance the inflow of FDI into the continent. Limitations: This study employed Dynamic System GMM which can produce variant results depending on the choice of instrument. Contribution: This study provides insight on the role of fiscal policy particularly taxation in explaining the inflow of FDI. Policymakers, multinational corporations, and other players in the global FDI market will appreciate the influence that tax exerts on FDI inflow. Keywords: 1. FDI 2. Financial freedom 3. Investment freedom 4. Labour freedom 5. Monetary freedom 6. Tax burden

Abstract: Purpose: The study examined the importance of internal control systems in financial accountability in Lira District Local Government, Uganda. Specifically, the study determined the importance of control activities, control environment, and monitoring of controls on financial accountability. Research methodology: A correlational design to establish the relationships between internal control systems and financial accountability, and regression analysis to explain the importance of internal controls on financial accountability were adopted. Results: Internal control systems account for 55.4% of the variations in financial accountability. Specifically, control environment and monitoring controls bear significant effects on financial accountability while control activities do not. Contribution: This is one of the original studies to assess Lira District Local Government. The study validates the contingent theory and extends its application in public administration. Limitations: The input of stakeholders from the community was ignored. Future researchers should consider investigating the role of community participation on the performance of district local governments in Uganda. Keywords: 1. Control activities 2. Control environment 3. Financial accountability 4. Internal control 5. Monitoring of activities

Dalam suatu Lembaga Pelatihan Kerja (LPK), di dalam program kerjanya selalu melaksanakan penilaian terhadap karyawan terutama para pengajar yang dilaksanakan setiap tahun. Hal ini dikarenakan pengajar merupakan bagian paling kritikal dalam terciptanya kualitas suatu lembaga pelatihan kerja. Penilaian dilaksanakan agar dalam pelaksanaan pengajarannya dapat menampilkan performa yang maksimal sehingga peserta pelatihan akan tertarik dengan performa pengajar. Selain itu pengajar juga memiliki peranan pernting dalam memberikan pembelajaran yang berkualitas. Untuk mendukung pemilihan pengajar terbaik yang diambil dari beberapa kriteria dan alternatif dibangun sebuah sistem dengan metode ELECTRE. Metode ini merupakan metode yang unggul dengan berlandaskan analisis antara concordance (kesesuaian) dan discordance (ketidaksesuaian). Metode ELECTRE mengolah data dan informasi menjadi alternatif yang dapat diandalkan juga sekaligus memberikan perangkingan pada alternatif yang sesuai yang diharapkan mampu memberikan hasil berupa alternatif yang terbaik. Sehingga penelitian ini dapat memberikan keputusan pilihan yang tepat pada sasaran pengajar, objektif, efektif dan efisien di LPK Anametri Learning Center.

Coronavirus disease 2019 (COVID-19) merupakan jenis penyakit baru yang diketahui menjangkiti manusia pada Desember 2019. Kasus COVID-19 telah menyebar di seluruh penjuru dunia termasuk di Indonesia. Salah satu provinsi dengan jumlah kasus COVID-19 yang cukup tinggi adalah Provinsi Riau. Tindakan mitigasi yang tepat diperlukan untuk mencegah wabah COVID-19. Berdasarkan studi pustaka, COVID-19 mewabah berdasarkan jarak terdekat. Ahli epidemiologi juga telah menggunakan metode clustering untuk mengelompokkan daerah-daerah yang terkena Pandemi COVID-19. Oleh karena itu, penelitian ini menggunakan teknik one hot encoding dan algoritma k-means clustering  untuk mengelompokkan daerah yang memiliki karakteristik data yang mirip. Penelitian ini menggunakan data 12 Kabupaten di Riau dengan tujuh fitur. Berdasarkan eksperimen, dihasilkan tiga klaster yaitu C1 (Pekanbaru, Kampar), C2 (Siak, Bengkalis, Rokan Hulu, Kuantan Singingi), dan C3 (Dumai, Indragiri Hilir, Indragiri Hulu, Pelalawan, Rokan Hilir, Meranti). Hasil klaster tersebut telah diuji dengan skor silhouette sebesar 0,6. Dengan demikian, dapat disimpulkan bahwa teknik one hot encoding dan algoritma k-means clustering berpotensi digunakan untuk mengelompokkan wilayah pandemi COVID-19 berdasarkan karakteristik data yang mirip.
