Centrifuge modelling of tunnelling below existing twin tunnels with different types of support
Underground Space, 2022 Tunnel excavation below existing tunnels produces ultimate and serviceability problems to the existing tunnels. The behaviours of induced stresses on the existing tunnels haven't yet been fully recognized.

A new approach to investigate the particle size effects in centrifuge modelling [PDF]
, 2016 Geotechnical centrifuge modelling provides an opportunity to examine novel and complex events in a well-controlled and repeatable environment. While grain interaction and contact dynamics are considered in centrifuge modelling, the soil is treated as a ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Scaling-up vaccine production: implementation aspects of a biomass growth observer and controller [PDF]
, 2009 This study considers two aspects of the implementation of a biomass growth observer and specific growth rate controller in scale-up from small- to pilot-scale bioreactors towards a feasible bulk production process for whole-cell vaccine against whooping ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

International Journal of Geo-Engineering, 2021 A numerical model based on the finite element framework was developed to predict the seismic response of saturated sand under free-field conditions. The finite element framework used a non-linear coupled hypoplastic model based on the u-p formulation to ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Aseismic measures for asphalt concrete core dams by dynamic centrifuge modelling tests
Yantu gongcheng xuebao, 2020 Dynamic centrifuge modelling tests are carried out to study the effectiveness of aseismic measures for a sand-gravel dam with asphalt concrete core wall under design earthquake. 2 models are used to simulate 2 dams without and with aseismic measures. The
