The unfolding COVID-19 pandemic has exposed the vulnerability of Pacific food system to externalities and had far-reaching impacts, despite small number cases recorded thus far. Measures adopted mitigate risk from have severe impacts on tourism, remittances, international trade, among other aspects political economy region, are impacting systems, security livelihoods. Of particular concern will be interplay between loss incomes availability affordability local imported foods. In this paper,...
The prediction of liquefaction and resulting displacements is a major concern for earth structures located in regions moderate to high seismicity. Conventional procedures used assess commonly predict the triggering depths 50 m or more. Remediation prevent curtail at these can be very expensive. Field experience during past earthquakes indicates that has mainly occurred less than about 15 m, some recent dynamic centrifuge model testing initially appeared confirm depth confining-stress...
Transport of solutes has been observed in the spaces surrounding cerebral arteries and veins. Indeed, transport found opposite directions two different around arteries. These findings have motivated hypotheses bulk flow within these spaces. The glymphatic circulation hypothesis involves cerebrospinal fluid from cortical subarachnoid space to parenchyma along paraarterial (extramural, Virchow-Robin) arteries, return (CSF) via paravenous channels. second interstitial lymphatic vessels basement...
In this paper we describe the development and initial testing of a tool for self-assessment affect while interacting with computer systems: Sensual Evaluation Instrument. We discuss our research approach within context existing affective HCI theory, stages evolution tool, its effectiveness.
As an alternative to advection, solute transport by shear-augmented dispersion within oscillatory cerebrospinal fluid flow was investigated in small channels representing the basement membranes located between cerebral arterial smooth muscle cells, paraarterial space surrounding vessel wall and large modeling spinal subarachnoid (SSS). Geometries were modeled as two-dimensional. Fully developed flows Darcy–Brinkman momentum equation passive equation. Scaling of enhancement axial relative...
It is widely recognised that anchored, nearshore fish aggregating devices (FADs) are one of the few practical 'vehicles' for increasing access to tuna help feed rapidly growing rural and urban populations in many Pacific Island countries territories (PICTs). However, considerable planning, monitoring research still needed understand fulfil potential FADs. Investments required (1) identify locations where FADs likely make greatest contributions food security (coastal) communities, yield good...
The Pacific food system has become progressively more integrated into global regimes. This integration had impacts on availability and consumption of food, population health, vulnerability to external drivers. We describe major elements the contemporary provide a foundation for analysis transitions public health outcomes. Although crop production doubled in last fifty years, it not kept pace with growth. deficit is increasingly filled by imported foods, particularly staples, meat sugar....
Wall shear stress (WSS) on anchored cells affects their responses, including cell proliferation and morphology. In this study, the effects of directionality pulsatile WSS endothelial morphology were investigated for grown in a Petri dish orbiting shaker platform. Time location dependent was determined by computational fluid dynamics (CFD). At low orbital speed (50 rpm), shown to be uniform (0-1 dyne/cm(2)) across bottom dish, while at higher (100 150 remained fairly near center fluctuated...
Recognized as an emerging global crisis in the mid-1990s, “nutrition transition” is marked by a shift to Western diets, dominated highly processed, sugar-sweetened, and high caloric foods. Occurring parallel these health transitions are dramatic shifts natural systems that underlie food availability access. Traditionally, environmental degradation ecosystem change, processes of nutritional transition, though often collinear potentially causally linked, have been addressed isolation. Food...
Extensive literature describes the importance of food environments (FEs) as a driver choices and nutrition outcomes; yet existing FE frameworks do not adequately capture diversity FEs relevant to Pacific Region. This limits identification opportunities in systems reduce multiple burden malnutrition. We present conceptual typology including six primary Pacific; wild; cultivated; kin community; informal retail; formal aid services. then apply this acquisition data from Solomon Islands 2012/13...
The Pacific region is experiencing a non-communicable disease epidemic largely driven by an ongoing nutrition transition from nutrient rich whole foods to imported staples and highly processed foods. Food trade major driver of this transition.

Abstract Hemolysis is caused by fluid stresses in flows within hypodermic needles, blood pumps, artificial hearts, and other cardiovascular devices. Developers of devices may expend considerable time effort testing prototypes, because there currently insufficient understanding how flow‐induced cell damage occurs to accurately predict hemolysis. The objective this project was measure deformation response a range flow conditions, develop constitutive model correlating stresses. An experimental...
Hemolysis (damage to red blood cells) is a long-standing problem in contacting devices, and its prediction has been the goal of considerable research. The most popular model relating hemolysis fluid stresses power-law model, which was developed from experiments pure shear only. In absence better data, this extended more complex flows by replacing stress equation with von Mises-like scalar stress. While validity also remains be confirmed, inconsistencies exist application, particular, two...
Cerebrospinal fluid (CSF) dynamics are thought to play a vital role in central nervous system (CNS) physiology. The objective of this study was investigate the impact spinal cord (SC) nerve roots (NR) on CSF dynamics. A subject-specific computational (CFD) model complete subarachnoid space (SSS) with and without anatomically realistic NR nonuniform moving dura wall deformation constructed. This CFD allowed detailed investigation velocities that is not possible vivo using magnetic resonance...
Ensuring healthy and sustainable food systems in increasing social, economic, ecological change is a key global priority to protect human environmental health. Seafood an essential component of these critical source nutrients, especially coastal communities. However, despite rapid transformations aquatic systems, our urgent need understand them, there dearth data connecting harvested production actualized consumption. Many analyses suggest institutional, legal, or technological innovations...
