Currently, over half of China’s trunk railways are located in permafrost regions. But to tackle the railway subgrade disease has always been the difficulty in the railway construction there. The influence that the dynamics performance of frozen silty clay has on permafrost subgrade is an important component in the researches towards permafrost subgrade. In this paper, the dynamics performance o...

The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...

Several recent ®eld studies have found disproportionately high barnacle settlement rates (expressed on a per-area basis) in situations where the amount of suitable substrate is reduced, either due to occupation by other individuals or to physical processes. We call this phenomenon the intensi®cation e€ect; it is not included in many models of benthic populations, which assume that the per-area ...

Ecology Letters (2012) 15: 338-346 ABSTRACT: Successful recruitment in shallow reef ecosystems often involves specific cues that connect planktonic invertebrate larvae with particular crustose coralline algae (CCA) during settlement. While ocean acidification (OA) can reduce larval settlement and the abundance of CCA, the impact of OA on the interactions between planktonic larvae and their pref...

BACKGROUND Settlements between doctors and patients provide a solution to complicated disputes. However, some disputes may be renewed as a result of negligence by both parties. The purpose of this study was to review the legal issues that may potentially arise during the preparation of settlement agreements and to propose a list of requirements for ensuring the effectiveness of these settlement...

Landfills settle due to its weight and biodegradation of waste. Biodegradation-induced settlement is a direct result of rearrangement of waste skeleton in response to the conversion of waste mass into landfill gases. Traditionally, the compressibility index based on settlement of clays is used to explain the settlement of waste. Literature review showed that there are limited research attempts ...

We investigate the effects of the settlement market of life insurance policies on the monopolistic insurer's profit and social welfare. We assume that consumers differ only in their liquidity needs, and that the insurer cannot discriminate consumers based on their liquidity needs. When the settlement market incurs no costs, we find that the existence of the settlement market enhances social wel...

Knowledge of larval behaviours of sessile marine invertebrates from release to recruitment and of the role these behaviours play in determining adult distributions is limited. In manipulative experiments using larvae from the Great Barrier Reef sponge Rhopaloeides odorabile, we quantified larval behaviours associated with vertical migration, phototaxis and swimming ability. We also measured set...

Larval settlement of the polychaete Hydroides elegans Haswell, 1883 is mediated by marine biofilms; complex agglomerates of bacteria, diatoms, fungi and protozoa enmeshed in a matrix of extracellular polymers (EPS). In our previous investigations, benthic diatoms were demonstrated to be potent mediators of larval settlement in H. elegans. The putative diatom-derived settlement cues were heat-st...

The problem of estimating the settlement of shallow foundations on granular soils is complex and not yet entirely understood. In the past, many empirical and theoretical methods have been developed for predicting the settlement of shallow foundations on granular soils; however, these methods are far from accurate and consistent. In recent times, artificial neural networks (ANNs) have been used ...
