18 Thermokarst lakes develop as a result of the thaw and collapse of ice-rich, permanently 19 frozen ground (permafrost). Of particular sedimentological importance are thermokarst 20 lakes forming in late Pleistocene icy silt (yedoma), which dramatically alter the land 21 *Manuscript Click here to download Manuscript: Farquharson text revised_clean.docx Click here to view linked References
the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...
Overview The integration of land administration processes and the collaboration of land agencies are considered essential for the effective delivery of developable land for housing production. However, in most countries, housing and land management policies are usually split between multiple government agencies. The background literature suggests that the activities of governments’ agencies tha...
Since the Land Administration Bureau was established in 1986, China has carried out the national land-use planning twice, of which the first was focused on "serving for social and economic development", and the second converted to “protecting arable land". At present a new round of land-use planning is ongoing (2005-2020), but the aims and requirements are even more and higher(Zheng Weiyuan,200...
We quantified groundwater discharge and associated nutrient fluxes to Monterey Bay, California, during the wet and dry seasons using excess (224)Ra as a tracer. Bioassay incubation experiments were conducted to document the response of bloom-forming phytoplankton to submarine groundwater discharge (SGD) input. Our data indicate that the high nutrient content (nitrate and silica) in groundwater ...
Land use change (LUC) is the most dynamic force in terrestrial carbon stock change, and it is imperative to account for the dynamics of LUC in carbon stock change when forming land use policies. This paper explored the impacts of LUCs on carbon (C) stocks at a county scale and detected changes of soil C stocks within a county-scale land use planning policy. The LUCs within 1979–2006 in Fuyang C...
Mollusca are the second largest phylum of the animal kingdom, forming a major part of the world fauna. The Gastropoda is the only class of molluscs which have successfully invaded land. They are one of the most diverse groups of animals, both in shape and habit. Among gastropods, land snails (subclass: Pulmonata) are one of the most numerous with almost 35,000 described species of the world. Th...
A widely held view of land plant relationships places liverworts as the first branch of the land plant tree, whereas some molecular analyses and a cladistic study of morphological characters indicate that hornworts are the earliest land plants. To help resolve this conflict, we used parsimony and likelihood methods to analyze a 6, 095-character data set composed of four genes (chloroplast rbcL ...
