Considering the unique conditions of deep and large subway foundation pit excavation affected by heavy rainfall in soil-rock composite strata, this paper employs finite element numerical simulation methods to study foundation pit instability under the influence of heavy rainfall. According to the hydraulic coupling conditions caused by rainfall, a fluid-solid coupling numerical model for a deep and large subway foundation pit in soil-rock composite strata is established in this paper.

In order to study the supporting structure under different distances between inner pit-in-pit and foundation pit, width and depth of pit-in-pit and general excavation depth of external foundation pit, PLAXIS is adopted to simulate the whole process of pit-in-pit excavation in a foundation pit of Shanghai. The factors which influence wall deflection are analyzed using orthogonal experimental design software. The results show that the factors which influence deformation of pit-in-pit and supporting structure of foundation pit are sorted with range value or sensitivity descending: depth of pit-in

Corrosion of the steel affects seriously its mechanical performance. Based on the finite element methods, strength tensile properties of corroded steel were studied. Pit shapes and pit depths, pit locations, etc on the mechanical behavior of steel were studied mainly. Pit depth is major cause of produce rust steel mechanical performance degradation, because there is an obvious stress concentration phenomenon around pit, cause steel mechanics performance degraded significantly. Pit shapes and lengths may also be affected steel mechanical properties.

Despite the widespread global reliance on pit latrines as improved sanitation systems, the decomposition of waste within pit latrines is poorly understood. One area needing elucidation is the characterization and function of microbial communities within pit latrines. To address this gap, we characterized the microbial communities of 55 lined pit latrines at three sampling layers from two communities in peri-urban Malawi. The microbial communities of the fecal sludge samples were analyzed for beta diversity, pathogen presence, and functional profiling. Household surveys were conducted and used

Abstract:
Degradation of tensile properties resulting from geometrical discontinuities due to localized pitting is usually evaluated in terms of the reduced section thickness associated with pit geometry which lowers the load carrying capacity of the structure. However, the effects of finer parameters associated with pit distributions such as pit area percent (PAP) are not usually taken into account. In this research, the effects of spacing, depth and PAP on tensile properties of a structural steel are investigated. Simulated pit distributions were produced on the gage sections of flat tensile specimens

Abstract:
The stochastic nature of pitting corrosion of metallic structures has been widely recognized. It is assumed that this kind of deterioration retains no memory of the past, so only the current state of the damage influences its future development. This characteristic allows pitting corrosion to be categorized as a Markov process. In this paper, two different models of pitting corrosion, developed using Markov chains, are presented. Firstly, a continuous-time, nonhomogeneous linear growth (pure birth) Markov process is used to model external pitting corrosion in underground pipelines. A closed-fo

For modern urban construction in the compacted conditions of new sites, the question of the stability of soil massifs under existing buildings is relevant.

The article provides a methodology for determining the area of influence of the pit on the soil foundations of adjacent buildings, depending on the type of enclosing structures and the depth of the pit used.

Abstract:
The most widely used process to reduce iron ore and to produce pig iron is the blast furnace. The blast furnace is a large source of CO2 emissions since it is a coal based process and due to that the main energy source and reducing agent is coke, it is difficult to reduce these further. IRONARC is a new method used to produce pig iron by reducing iron ore and all the energy used for heating comes from electricity, which gives the opportunity to use renewable resources. The process uses plasma generators that inject gas at high temperature and velocity into a slag that consists of iron oxides.

Abstract Shot peening is used in many industrial applications, e.g. steam turbine blades, to induce near-surface compressive residual stresses and reduce the likelihood of failure by fatigue, corrosion fatigue and stress corrosion cracking.

However, the depth of the compressive stress layer is typically only about 250 μm and this poses the question as to the retained benefit when corrosion pits develop to varying depth.

Abstract:
The RSTRENG 3.0 (Windows Version) software program and users manual were developed to enhance the usability and options available in the original program RSTRENG. RSTRENG was developed as part of AGA PR-3-805, "A Modified Criterion for Evaluating the Remaining Strength of Corroded Pipe." Like the original version of RSTRENG, RSTRENG 3.0 can be used by pipeline operators to evaluate the remaining strength of corroded pipe. The required user inputs are pipe diameter, wall thickness, grade of the pipe material, and a series of pit depth and length measurements. The new version of the software act

Abstract:
The technology and procedures for the inspection of pipelines from offshore production and process facilities to shore or other offshore installations has developed rapidly in recent years. This rapid development can be attributed to several factors including pipeline operators protecting their investment in their lines, heightened environmental protection concerns, and increasing regulatory requirements. A limited number of the offshore pipeline systems in the U.S. currently include the ability to inspect the trunkline using either an ultrasonic or magnetic particle inspection pig. This pig i

Abstract:
As part of ARL’s Research Library Impact Framework initiative, a team from the University of Pittsburgh Library System addressed how special collections support teaching, learning, and research. This project developed a toolkit that allows measurement of impact of engagement with primary sources. The University of Pittsburgh (Pitt) initially worked with University of California, Irvine (UCI) to develop student learning outcomes based on the ACRL/RBMS–SAA Guidelines for Primary Source Literacy and used a logic model framework to identify three types of outcomes: initial (attainment of new skill

Abstract:
Landscape-scale changes from climate change in the Arctic affect the soil thermal regime and impact the depth to permafrost in vulnerable tundra watersheds. When top-down thaw of permafrost occurs, oxygen and porewaters infiltrate deeper in the soil column exposing fresh, previously frozen material and altering redox conditions. A gap remains in understanding how redox stratifications in thawing permafrost impact the geochemistry of watersheds in response to climate change and how investigations into redox may be scaled by coupling extensive geophysical mapping techniques.

Abstract:
An industry survey, dominated by PRCI member companies, was undertaken to gather key information regarding the design, operation and inspection of well bore casing strings. The aim of the survey was to gather information regarding the design standards, fields, gas composition, completion configuration, operational details, inspection methods and type of damage found. Survey results representing 67 storage facilities with a total of 4724 wells were received. This represents approximately 16% of US gas storage facilities. Facilities with initial completion dates between 1920 and 1990 were repres

Abstract:
Auction-based renewable electricity procurement has the potential to attract private investment and lower prices, but its design and implementation can be challenging. Since 2018, Ethiopia has organised auctions to procure new capacity from independent power producers (IPPs). Based on an in-depth study of the political economy, this policy briefing explores factors impeding the design and implementation of IPPs’ projects, including the shortage of foreign currency and convertibility of the Ethiopian birr to repatriate profits. It proposes measures to overcome these obstacles and mitigate risks
