Stability and Deformation Analysis of Landslide under Coupling Effect of Rainfall and Reservoir Drawdown

Landslides, a devastating hazard, continue to happen, affecting the lives of thousands of people each year. Fluctuation in the Reservoir Water Level (FRWL) is one of the leading features disturbing the slope stability in reservoir areas, drawdown is more crucial than the rise to the stability of landslide. Latest studies grounded on field investigation and monitoring data propose that landslides in reservoir areas are initiated not solely by one issue like precipitation or FRWL, however conjointly by their joint actions. Zhulinwan landslide in Chongqing, China, Three Gorges Reservoir (TGR) area was analyzed by field investigation and numerical modelling to evaluate the characteristics of the landslide. The changes in landslide stability and deformation under the effect of reservoir drawdown and rainfall is analyzed using GEOSLOPE Software. The seepage analysis is done using SEEP W Model, afterward deformation and stability analysis using SLOPE W and SIGMA W respectively. The analysis confirmed that the coupling effect of reservoir drawdown at 1.2 m/d and rainstorm of once in 50 years return period makes the landslide unstable. Moreover, deformation at the same condition is maximum 0.049 m. The findings may be used by local authorities to help make decisions about slope stabilization in the event of a confirmed significant rainfall event. Doi: 10.28991/cej-2021-03091713 Full Text: PDF

A practical resource management prototype for mobile networks

Network slicing is a promising approach to meet the diverse requirements of the various use cases in the 5G networks. Hence, the mobile operators are moving forward to leveraging network slicing in order to measure up with the individual service expectations in their networks. Deploying different network slice types requires the global view of the network and the automated orchestration and management of the underlying resources. This is facilitated by utilizing software-defined networking and network function virtualization as the 5G key-enabler technologies. In this paper, we propose a practical network slicing resource management scheme which is comprised of a dynamic, priority-based resource allocation cooperating with an admission control unit. Adopting the proposed dynamic resource allocation would allow the admission control to comply with more NS requests while ensuring the desired requirements of the existing network slices. To validate the effectiveness of such a mechanism in a real environment, we take advantage of the features provided by OpenAirInterface and FlexRAN to efficiently manage multiple isolated network slices. In particular, we evaluate the significance of the network slicing, the isolation degree among created slices, and the effectiveness of the proposed scheme through several practical scenarios.
Preparation of K Modified Three-Dimensionally Ordered Macroporous MnCeOx/Ti0.7Si0.3O2 Catalysts and Their Catalytic Performance for Soot Combustion

Soot particles in diesel engine exhaust is one of the main reasons for hazy weather and elimination of them is urgent for environmental protection. At present, it is still a challenge to develop new catalysts with high efficiency and low cost. In this paper, a kind of K modified three-dimensionally ordered macroporous (3DOM) MnCeOx/Ti0.7Si0. 3O2 catalysts are designed and synthesized by a sample method. Due to the macroporous structure and synergistic effect of K, Mn, and Ce, the KnMnCeOx/Ti0.7Si0. 3O2 (KnMnCeOx/M-TSO) catalysts exhibit good catalytic performance for soot combustion. The catalytic activity of K0.5MnCeOx/M-TSO was the best, and the T10, T50, and T90 are 287, 336, and 367 °C, respectively. After the prepared catalyst was doped with K, the physicochemical properties and catalytic performance changed significantly. In addition, the K0.5MnCeOx/M-TSO catalyst also somewhat exhibits sulfur tolerance owing to it containing Ti. Because of its simple synthesis, high activity, and low cost, the prepared KnMnCeOx/M-TSO catalysts are regarded as a promising candidate for application.
Comparative analyses of the nutraceutical potentialities of selected Indian traditional black rice (Oryza sativa L.) landraces

The present investigation aims to explore the importance of some traditional black rice varieties with their nutraceutical properties. The beneficial properties of these varieties remain unknown to the majority of the population due to the inadequate data. Decorticated rice grains of four black rice varieties were evaluated and compared with two commonly consumed white rice varieties - Gobindabhog (traditional aromatic) and BPT 5204 (modern high yielding variety). The sugars and total lipid levels were similar in Gobindabhog and BPT 5204. The black rice varieties, however, had considerably greater protein, thiamin, riboflavin, pantothenic acid, pyridoxine, and antimicrobial activities compared to the two selected white rice varieties. The ICPMS analysis of black rice grains showed that the former also had higher levels of Mn, Fe, and Zn than the white rice varieties. However, BPT 5204 contained a greater amount of Cu than the black rice varieties. Total flavonoid and phenolic content, as well as antioxidant potentiality of black rice varieties were also considerably higher than those of the white rice varieties.
Description of Osmotic Dehydration of Melon Cubes using a Three-dimensional Diffusion Model: An Algorithm to Determine the Effective Diffusivity

Abstract This paper aims to study the transient mass diffusion during the osmotic dehydration of melon cubes, using the analytical solution of the diffusion equation with boundary condition of the first kind. Two techniques are used to determine the effective mass diffusivity, using experimental data. In technique 1, available in the literature, the domain of the effective diffusivity is scanned from a value close to zero, until the minimum value of the objective function (Chi-square) is determined. Technique 2, proposed in this paper, uses an algorithm based on the optimal removal of experimental points, until obtaining the objective function with a minimum value, allowing to determine the optimal value for the effective mass diffusivity. The obtained values for diffusivity and statistical indicators revealed that both techniques generate equivalent results and allowed to satisfactorily describe the kinetics of osmotic dehydration of melon cubes. However, technique 2, proposed in this paper, is much faster than technique 1, in the determination of effective mass diffusivity, for all analyzed sets of experimental data.
Impact of Youth and Adult Informal Science Educators on Youth Learning at Exhibits

Abstract The impact of educators in informal science learning sites (ISLS) remains understudied from the perspective of youth visitors. Less is known about whether engagement with educators differs based on the age and gender of both visitor and educator. Here, visitors (5–17 years old) to six ISLS in the United States and United Kingdom (n = 488, female n = 244) were surveyed following an interaction with either a youth (14–18 -years old) or adult educator (19+ years old). For participants who reported lower interest in the exhibit, more educator engagement was related to greater self-reported learning. Younger children and adolescents reported more engagement with an adult educator, whereas engagement in middle childhood did not differ based on educator age. Participants in middle childhood showed a trend toward answering more conceptual knowledge questions correctly following an interaction with a youth educator. Together, these findings emphasize the promise of tailoring educator experiences to visitor demographics.
Forensic Protocols and Investigation of Crimes in Pakistan: A Case of Sindh

This study was conducted to examine the importance of the existing Forensic Protocol procedure adopted for the investigation of various crimes in Sindh, especially in the Karachi and Hyderabad areas. Forensic science plays an imperative role in any criminal investigation to identify the culprit using scientific methods. In current study, the forensic protocol discusses the roles of the following respondents: healthcare providers, lawyers, law enforcement agents, forensic scientists and the prosecution. Police in Sindh Province is a mix of human resources with different levels of education and training. When police participants were asked if they had ever studied forensics, it was found that 47.1% had studied forensics, while 52.9% denied it. It means that 52.9% of the surveyed police officers have poor forensic knowledge and experience. With the help of qualitative research methodology, this research has been analyzed. The potential of forensic science in Sindh is based on overcoming limitation and enhancing development characteristics. Barriers include traditional attitudes, lack of implementation, lack of funding, lack of trained personnel, equipment, and laboratories. Forensic scientific investigations are possible if the police establish a new professional culture, professional ethics, scientific methods and tools, amplifying training, and establishing forensic laboratories.
Trimmer: An Automated System for Configuration-Based Software Debloating

Software bloat has negative implications for security, reliability, and performance. To counter bloat, we propose Trimmer, a static analysis-based system for pruning unused functionality. Trimmer removes code that is unused with respect to user-provided command-line arguments and application-specific configuration files. Trimmer uses concrete memory tracking and a custom inter-procedural constant propagation analysis that facilitates dead code elimination. Our system supports both context-sensitive and context-insensitive constant propagation. We show that context-sensitive constant propagation is important for effective software pruning in most applications. We introduce sparse constant propagation that performs constant propagation only for configuration-hosting variables and show that it performs better (higher code size reductions) compared to constant propagation for all program variables. Overall, our results show that Trimmer reduces binary sizes for real-world programs with reasonable analysis times. Across 20 evaluated programs, we observe a mean binary size reduction of 22.7 percent and a maximum reduction of 62.7 percent. For 5 programs, we observe performance speedups ranging from 5 to 53 percent. Moreover, we show that winnowing software applications can reduce the program attack surface by removing code that contains exploitable vulnerabilities. We find that debloating using Trimmer removes CVEs in 4 applications.
Structural Controls Over the 2019 Ridgecrest Earthquake Sequence Investigated by High‐Fidelity Elastic Models of 3D Velocity Structures

We develop finite element models of the coseismic displacement field accounting for the 3D elastic structures surrounding the epicentral area of the 2019 Ridgecrest earthquake sequence containing two major events of Mw7.1 and Mw6.4. The coseismic slip distribution is inferred from the surface displacement field recorded by interferometric synthetic aperture radar. The rupture dip geometry is further optimized using a novel nonlinear‐crossover‐linear inversion approach. It is found that accounting for elastic heterogeneity and fault along‐strike curvilinearity improves the fit to the observed displacement field and yields a more accurate estimate of geodetic moment and Coulomb stress changes. We observe spatial correlations among the locations of aftershocks and patches of high slip, and rock anomalous elastic properties, suggesting that the shallow crust's elastic structures possibly controlled the Ridgecrest earthquake sequence. Most of the coseismic slip with a peak slip of 7.4 m at 3.6 km depth occurred above a zone of reduced S‐wave velocity and significant post‐Mw7.1 afterslip. This implies that viscous materials or fluid presence might have contributed to the low rupture velocity of the mainshock. Moreover, the zone of high slip on the northwest‐trending fault segment is laterally bounded by two aftershock clusters, whose location is characterized by intermediate rock rigidity. Notably, some minor orthogonal faults consistently end above a subsurface rigid body. Overall, these observations of structural controls improve our understandings of the seismogenesis within incipient fault systems.
Mitigating the Default? The Influence of Ingroup Diversity on Outgroup Trust

Maintaining social cohesion in times of increasing diversity is a major challenge of modern societies. Mitigating defaults in group-based trust could be a solution because they are often driven by stereotypes and ingroup favoritism. Ingroup diversity could be a means to achieve such a mitigation given that it increases cognitive flexibility and cognitive flexibility changes defaults in trust – in the sense of increasing low and reducing high trust. We tested whether representing one’s ingroup as high (compared to low) in diversity mitigates defaults in group-based trust using a variety of well-established manipulations of ingroup diversity and measures of trust. None of the four well-powered studies (total N = 885), we conducted provided support for our hypothesis. However, an internal meta-analysis revealed a significant but very small effect in support of our prediction (r = 0.07, 95% CI [0.01, 0.14]). Thus, a diverse representation of the ingroup asserts a mitigating impact on group-based trust, but the size of the effect is very small. Thus, real world interventions should not rely on the current effect.
High precision tests of QED Measurement of the alpha-particle and helion rms charge radius and the transition energies in highly-charged ions

Ce travail vise a contribuer a l’amelioration de notre connaissance de l’electrodynamique quantique des etats lies, par des mesures de haute precision dans des etats exotiques de la matiere. Bien que notre connaissance de l’electrodynamique quantique des etats lies et du probleme relativiste a plusieurs corps aient fait des progres importants ces dernieres annees, il reste des questions fondamentales dont la resolution necessite d’augmenter le nombre et la precision des tests experimentaux. La premiere partie de ce travail a ete realisee dans le cadre de l’experience recente sur les ions muoniques d’helium (μ4He+ et μ3He+) conduite par la collaboration CREMA. Cette experience vise a fournir de nouvelles valeurs precises pour les rayons de charge moyens des noyaux des isotopes stables de l’helium. Ces valeurs sont extraites de la mesure du deplacement de Lamb, c’est-a-dire, de la mesure de la difference d’energie entre les Etats 2S − 2P. Une mesure des energies de transition d’une precision d’au moins 50 ppm, permet de determiner les rayons de charge des noyaux des isotopes d’helium avec une incertitude de 0,03%, dix fois plus precise que les resultats precedents obtenus a partir de la diffusion d’electrons. La deuxieme partie de ce travail a ete de realiser des mesures de haute precision de transitions de rayons X dans des ions fortement charges, a l’aide d’un spectrometre a double cristal plan. Ces ions etaient produits dans le plasma d’une source d’ions de type ECRIS (electron-cyclotron resonance ion source). Le spectrometre utilise est non seulement capable de fournir des mesures de haute precision, mais aussi des mesures sans reference a des energies de transition theorique ou experimentales. Quatre energies de transition de n = 2 → n = 1 ont ete mesurees pour des ions d’argon de trois etats de charge differents, heliumoide, lithiumoide et berylliumoide, avec une precision meilleure que 3 ppm. La largeur naturelle de chaque raie a egalement ete obtenue experimentalement. Les resultats trouves sont en excellent accord avec les calculs theoriques les plus recents.
Homeownership and Students’ Achievement in Public Schools in the U.S. State of Georgia

ABSTRACT We investigate the impact of neighborhood homeownership rates on students’ achievement in public schools in the U.S. state of Georgia. Homeownership and students’ achievement are likely to be endogenously determined at the neighborhood level. We correct for this endogeneity concern using population growth as the instrument for the neighborhood homeownership rate. The findings suggest that a 1-percentage-point increase in homeownership rate at the census tract level increased the percentage of proficient learners and above in third-grade reading by 0.24 percentage points, and the effects are stronger—economically and statistically—in estimates that correct for the endogeneity of neighborhood homeownership rates. Further, the effects of homeownership are much larger in the sample of low-income, less affluent, or more black or African American-dominated neighborhoods, compared with the overall sample.
Acute lymphoid leukemia developing in the course of Crohn's Disease: Are there any guilty agents?

Anti-tumor necrosis factor-alpha drugs (anti-TNF-α), which are monoclonal antibodies, have revolutionized the treatment of severe and refractory inflammatory bowel disease in the last two decades. However, these drugs pose a risk for the formation of hematological malignancies such as lymphoma and acute leukemia. To our knowledge, acute lymphoblastic leukemia has been reported in the literature in only two Crohn's patients with a history of anti-TNF-α therapy. In this article, we reported a case of Philadelphia chromosome positive acute lymphoid leukemia occurring during the course of disease with a history of azathioprine and anti-TNF-α treatment with the diagnosis of Crohn's disease. In addition, we wanted to emphasize that the patient was followed up in remission for five years after allogeneic bone marrow transplantation although he did not receive treatment for Crohn's disease.
Application of marine collagen for stem-cell-based therapy and tissue regeneration (Review)

Tissue engineering and regenerative medicine is becoming an important component in modern biological scientific research. Tissue engineering, a branch of regenerative medicine, is a field that is actively developing to meet the challenges presented in biomedical applications. This particularly applies to the research area of stem cells and biomaterials, due to both being pivotal determinants for the successful restoration or regeneration of damaged tissues and organs. Recently, the development of innovative marine collagen-based biomaterials has attracted attention due to the reported environmentally friendly properties, the lack of zoonotic disease transmission, biocompatibility, bioactivity, the lack of ethics-related concerns and cost-effectiveness for manufacturing. The present review aimed to summarize the potential application and function of marine collagen in stem cell research in a medical and clinical setting. In addition, the present review cited recent studies regarding the latest research advances into using marine collagen for cartilage, bone, periodontal and corneal regeneration. It also characterized the distinct advantages of using marine collagen for stem cell-based tissue repair and regeneration. In addition, the present review comprehensively discussed the most up to date information on stem cell biology, particularly the possibility of treating stem cells with marine collagen to maximize their multi-directional differentiation capability, which highlights the potential use of marine collagen in regenerative medicine. Furthermore, recent research progress on the potential immunomodulatory capacity of mesenchymal stem cells following treatment with marine collagen to improve the understanding of cell-matrix interactions was investigated. Finally, perspectives on the possible future research directions for the application of marine collagen in the area of regenerative medicine are provided.
Economic Returns from Cereal and Cereal/Vetch Forage Crops Grown as Fodder Conservation Options for Beef and Sheepmeat Production

The economic return from cereal or cereal/vetch crops was determined using previously published and new agronomic and herbage quality data from experiments conducted at four sites across southern New South Wales, Australia, over four years (2008 to 2011), to evaluate the agronomic and quality parameters of two wheat (Triticum aestivum L.), two barley (Hordeum vulgare L.), two oat (Avena sativa L.), and one triticale (x Triticosecale) variety, grown as monocultures or in combination with purple vetch (Vicia benghalensis L.). The crops (n = 193) were harvested at different stages of cereal maturity and ranged in metabolisable energy (ME) from 6.9 to 13.1 MJ/kg DM and crude protein (CP) content from 49.8 to 215.4 g/kg DM. Individual crop ME and CP content was used to predict dry matter intake and liveweight gain using Grazfeed decision support tool, assuming the forages were fed as the sole diet to either crossbred lambs or British breed steers, with initial liveweights of 30 or 300 kg respectively. Animal parameters and yield were used to estimate gross margins (GM) for each crop based on estimated fixed and variable costs, including sowing and fertiliser costs, and harvesting and feedout costs. Feed quality determined animal production and potential income per animal, while yield determined potential income per hectare for any given level of animal production. Across the three years GM ranged from −$1489 to $5788 in sheep and from −$1764 to $647 in cattle. Reducing costs or increasing livestock value improved the GM. The highest GM were for lambs fed crops with high ME, adequate CP, and good yields. Increasing yield reduced the GM when growth rates were low, and costs exceeded the value of liveweight gain.
Aerosol properties in cloudy environments from remote sensing observations: a review of the current state of knowledge

Aerosol properties are fundamentally different near clouds than distant from clouds. This paper reviews the current state of knowledge of aerosol properties in the near low cloud environment and quantitatively compares them with aerosols far from clouds, limited in scope to remote sensing observations. It interprets observations of aerosol properties from different sensors using satellite, aircraft and ground-based observations. The correlation (and anticorrelation) between proximity to cloud and aerosol properties is discussed. Retrieval artifacts in the near-cloud environment are demonstrated and quantified for different sensor attributes and environmental conditions. Finally, the paper describes the possible corrections for near-cloud enhancement in remote-sensing retrievals. This study is timely in view of science definition studies for NASA’s Aerosols-Clouds, Convection and Precipitation (ACCP) mission, which will also seek to directly links aerosol properties to nearby clouds.
