Abstract:
Loess has a unique structure and water sensitivity, and the immersion of loess leads to many tunnel lining problems in shallowly buried tunnels. Based on a tunnel in Gansu Province in China, two failure glide planes of a shallowly buried loess tunnel and their immersion modes are summarized. Finite element calculation of the structural Duncan-Chang constitutive model is realized via the secondary development of finite element software, by which the loads on the secondary lining are calculated and verified in comparison with measured results. The load characteristics of the secondary lining are

The construction time of secondary lining in loess tunnel has been the focus of attention in the tunnel field, but no specific quantitative discriminant index of the construction time of the secondary lining has been applied.

Abstract:
The relationship between the source and sink of atmospheric CO2 has always been a widely discussed issue in global climate change research. Recent studies revealed that the chemical weathering of carbonate rocks contributed to 1/3 (~0.5 Pg C/yr) of the missing carbon sinks (MCS) globally, and there are still 2/3 of MCS (~0.5 Pg C/yr) that need to be explored. As one of the main overburdened parts of the earth, loess is one of the important driving factors for atmospheric CO2 consumption. Here, we elaborated on the dissolution process and the carbon sink effect from carbonate and silicate miner

AbstractIn the midwestern United States, large rivers draining the Laurentide Ice Sheet (LIS) were the most important sources of Peoria Loess, deposited during the last glaciation. Loess deposition near those rivers may have responded primarily to ice-sheet dynamics rather than direct effects of climatic change. In contrast, it has been proposed that thick Peoria Loess on the central Great Plains was derived mainly from unglaciated landscapes northwest of the main loess deposits. In this study, transport directions inferred from more than 600 measurements of Peoria Loess thickness in Nebraska

The wind–water erosion crisscross region, where the topography is complicated, is the most severe area of soil erosion on the Loess Plateau. The wind and terrain both have an impact on the soil water erosion process. In order to evaluate the effects of sand cover on runoff and soil loss characteristics, a series of experiments was conducted in two contrasting treatments. One treatment was a bare loess soil slope serving as the control, and the others were sand-covered loess slopes with five different slopes.

There is a constant struggle to increase the efficiency in gas turbines, where one method is to have a higher inlet temperature to the turbine. Often, this results in temperatures higher than the critical temperature of the materials, which makes cooling of the components an important part of the turbine. The cooling air is tapped from the compressor, and has hence required work while being compressed, but since it is removed from the thermodynamic cycle it will not provide any work in the turbine stages.

Abstract:
Flow separations often take place in the junction of blades and endwalls and limit seriously the aerodynamic loading increase of turbomachinery, which are caused mainly by mixing of the boundary layers on blades and endwall surfaces and the transverse secondary flow generated by the pressure difference between the pressure and suction side. Firstly, focusing on a linear diffusion cascade with 42 degrees turning angle, it can be found that the transverse secondary flow can be reduced by inviscid hub and the flow separation is eliminated further through the numerical comparison between the visco

Abstract:
Women with test scores above a secondary school admission threshold for preferred schools increase their years of education and entrance to university. Men increase neither years of schooling nor university attendance. Females with scores just above an admission threshold are significantly less likely to experience a job loss during the recession than those just below. Moreover, each year of education reduces the probability of job loss. The protective effects of education are related to workers attributes and not to job characteristics or access to childcare. Education, in and of itself, has

Abstract:
The COVID-19 pandemic brought school systems to a halt across the globe. In Belize, remote learning was challenging owing to limited access to educational technologies and lack of familiarity with remote learning among teachers. This study draws on national standardized exams and specific achievement testing to assess pandemic-related learning losses at the primary education level. Based on administrative data, the study also analyzes changes in student enrollment, dropout rates, and grade repetition at the primary and secondary levels. We find that school closures resulted in significant lear

Abstract:
Corrosion metal-loss is one of the major damage mechanisms to transmission pipelines worldwide. Several methods have been developed for assessment of corrosion defects, such as ASME B31G, RSTRENG and LPC. These methods were derived based on experimental tests and theoretical/numerical studies of the failure behavior of corroded pipelines subjected only to internal pressure loading. In the vast majority of cases, internal pressure loading will be the main loading mechanism on the pipeline. However, there may be instances when pipelines could also be subjected to significant loading from the env

Abstract:
Review question / Objective: The primary objective of this scoping review is to understand the extent and type of evidence in relation to moral injury in social work staff. The secondary objective is to establish how moral injury has been defined in the literature in the context of social work. The review question is: what is currently known about moral injury in social work staff? Background: Moral injury is the lasting psychological, spiritual and social harm caused by committing, experiencing or observing transgressions of deeply held moral values, beliefs and expectations (Haight et al., 2

Abstract:
This study examines the economic impacts of COVID-19-related school closures in the primary, secondary, and tertiary levels along with the implications to future labor productivity in Asia and the Pacific. School closures due to COVID-19 created substantial disruptions in education, and this will impact the skills of students and their productivity when they mature as professionals. This study examines medium- and long-term economic impacts of COVID-19-related school closures using the Global Trade Analysis Project or GTAP. It also evaluates the labor productivity effect per year of schooling

Abstract:
Federal regulatory standards require repair of dents with depths exceeding 6% of the pipeline diameter and for dents exhibiting signs of mechanical damage interacting with secondary features. However, leaks have been known to occur at dents with depths less than 3% of the pipe diameter and dents interacting with secondary features have been known to survive in service for extended periods of time. With the improvement in ILI technologies, there is an increase in detection of shallow dents and shallow dents interacting with corrosion features and a large population of these features exist curre

Abstract:
Fungal pathogens of plants produce a diverse array of small molecules. Often referred to as secondary metabolites because they were thought to be dispensable for basic functions, they may indeed have central roles as signals for the fungal cell, and in interactions with the host. We have identified more than a dozen genes encoding nonribosomal peptide synthetases (NPS) in Cochliobolusheterostrophus, the agent of southern corn leaf blight. The aim of this project was to identify roles of these genes in stress responses and signaling. The first objective was to test a complete collection of C. h
