In the petroleum industry, one of the most serious problems encountered during cementing is the failure at the bonding interface. Many measures including casing-sand adhesion have been developed to improve cementing bond strength. However, due to the lack of detailed study of the technique, many questions remain. The primary goal of this study is to investigate the influence of casing-sand adhe...

The hydro-mechanical coupling transport process of sand production is numerically investigated with special attention paid to the bonding effect between sand grains. By coupling the lattice Boltzmann method (LBM) and the discrete element method (DEM), we are able to capture particles movements and fluid flows simultaneously. In order to account for the bonding effects on sand production, a cont...

Hydrophobic sand is a relatively new method of urine collection in the rodent, comparable to the established method using a metabolic cage. Urine samples are often used in rodent research, especially for biomarkers of health changes after internal contamination from embedded metals, such as in a model of a military shrapnel wound. However, little research has been done on the potential interfer...

We present a continuous model capable of demonstrating some salient features of aeolian sand ripples: the realistic asymmetric ripple shape, coarsening of the ripple field at the nonlinear stage of ripple growth, saturation of ripple growth for homogeneous sand, typical size segregation of sand, and formation of armoring layers of coarse particles on ripple crests and windward slopes if the san...

Over the past decade, considerable research has linked traumatic experiences, including childhood trauma, to the development of psychotic symptoms. More recently, the concept of dissociation has been connected to psychosis, particularly auditory hallucinations, as well as to the historical conception of schizophrenia. In this workshop, Professor Andrew Moskowitz, the lead editor of ‘‘Psychosis,...

BACKGROUND The Theory of Change (ToC) approach has been used to develop and evaluate complex health initiatives in a participatory way in high income countries. Little is known about its use to develop mental health care plans in low and middle income countries where mental health services remain inadequate. AIMS ToC workshops were held as part of formative phase of the Programme for Improvin...

We provide the first formal foundation of SAND attack trees which are a popular extension of the well-known attack trees. The SAND attack tree formalism increases the expressivity of attack trees by introducing the sequential conjunctive operator SAND. This operator enables the modeling of ordered events. We give a semantics to SAND attack trees by interpreting them as sets of series-parallel g...

The 9th edition of the Intelligent Environments Conference (IE’13) will be held at Athens, Greece, 18 and 19 of July 2013. This is the fifth time this conference will host a range of international and multidisciplinary workshops. This year, a total of 15 workshops are being prepared and are already waiting for contributions. Amongst all workshops, 9 of them are being held independently and the ...

Remote sensing and field evidence are used to describe sand deposits found in associated pathways of emplacement in the eastern Mojave Desert. Two separate pathways are identified here: one extending eastward from the Bristol Playa through the Cadiz and Danby Playas and Rice Valley to the Colorado River, and a second parallel path extending eastward from Dale Playa through the Palen and Ford Pl...
