Migraine as a Common Extra-Intestinal Presentation of Celiac Diseaseby
Abstract
Celiac disease (CD) is a common gluten-related enteropathy that presents several extra-intestinal manifestations. Migraine is globally recognized as one of the most diffuse primary headaches. The present paper aims to review the current evidence on the possible association between CD and migraine. Both adults and children having CD exhibit a high prevalence of migraine. However, screening for CD in an unselected population of migraineurs demonstrated contrasting results. Brain imaging may reveal cerebral calcificat [...] 1808 17215 |
Crustal Reservoir Flow Simulation for Long-Range Spatially-Correlated Random Poroperm Mediaby
Abstract
In interest of accurately modelling wellbore production in convective geothermal systems, we draw attention to two approaches to numerical simulation of crustal fluid flow. The historical "strong" approach simulates the fluid mass conservation condition on a localised finite difference mesh approximation to poroelastic continua. The more flexible "weak" approach globally enforces fluid mass conservation by in effect integrating over all numerical mesh cells. Strong formulation crustal flow simulation emerged from n [...] 1806 9264 |
Fluorescence in Situ Hybridisation (FISH) is the First Tool to Identify Hypodiploidy in Paediatric Acute Lymphoblastic LeukaemiaAbstract
Hypodiploidy has a low incidence in childhood acute lymphoblastic leukaemia (ALL). Patients are usually stratified into three subgroups, to allocate the correct treatment according to their ploidy level: high hypodiploidy (40-45 chromosomes), low hypodiploidy (33-39 chromosomes) and near haploidy (23-29 chromosomes). In this paper, a case is presented of near-haploid childhood ALL where fluorescence in situ hybridisation (FISH) provided an insight into the near-haploidy chromosomal aberration initially missed on ro [...] 1805 12711 |

Computational Micromechanics for the Optimization of Compression Strength of Unidirectional Carbon Fiber Composites for Use in Wind Turbine Bladesby
Abstract
As wind turbine blades grow longer, new design parameters gain additional importance such as blade weight, tip deflection and material cost. These parameters require designers to relook at carbon fiber as a potential design solution. However, the composite materials in wind turbine blades are subjected to significant compressive loading, and the compressive strength of carbon fiber reinforced polymer (CFRP) composites is much lower than its tensile strength. This reduction in compression strength is due to a change [...] 1802 9936 |
