Universal Graphs at $\aleph_{ω_1+1}$ and Set-theoretic Geology [PDF]

open access: yesarXiv, 2016
This thesis consists of two parts: the construction of a jointly universal family of graphs, and then an exploration of set-theoretic geology. Firstly we shall construct a model in which $2^{\aleph_{\omega_1}}=2^{\aleph_{\omega_1+1}}=\aleph_{\omega_1+3}$ but there is a jointly universal family of size $\aleph_{\omega_1+2}$ of graphs on $\aleph_ ...

The effect of thermal–hydro–mechanical coupling on grouting in a single fracture under coal mine flowing water conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Higher temperature leads to a better relative sealing efficiency with a slow flow rate. Temperature change shows a negative correlation with the seepage pressure and the grouting pressure. The “equivalent grouting point offset” effect of grouting shows an eccentric elliptical propagation.

Geology of the Moscoviense Basin

open access: yes, 2011
[1] The Moscoviense Basin, on the northern portion of the lunar farside, displays topography with a partial peak ring, in addition to rings that are offset to the southeast. These rings do not follow the typical concentric ring spacing that is recognized

Elevated temperature effects on swelling pressure of compacted bentonite

open access: yesDeep Underground Science and Engineering, EarlyView.
We present a set of new experimental investigations on the effects of elevated temperature on the swelling pressure development of compacted bentonite. This research was motivated by an emerging interest in using bentonite as a plug material in oil and gas well abandonment.

Fatores Hidrogeológicos no Estudo da Intrusão Salina em Aqüíferos Costeiros da Região Litorânea do Município de Maricá - RJ. [PDF]

open access: yesAnuário do Instituto de Geociências, 2007
The oceanic area of Maricá, in the east coast of the Rio de Janeiro State, relies on groundwater as its mainsource of fresh water supply along with the use of water tank trucks. With the increasing demand of water resources,water supply and contamination

Geology and mapping of dark terrain on Ganymede and implications for grooved terrain formation

open access: yes, 2000
Geological mapping of regional and high-resolution Galileo images reveals a variety of units and structures within Ganymede's dark terrain. We have made a detailed study of areas within Galileo, Marius, and Nicholson Regiones in order to investigate the ...
