Sensitivity analysis and performance evaluation of the PEMFC using wave-like porous ribs
Applied Thermal Engineering, 2019An approachable way to improve proton exchange membrane fuel cell’s (PEMFC) performance at low current densities is to enhance the convective heat transfer in the gas flow channel (GFC).

The intrathoracic rib is a rare anomaly. Despite this, it has distinctive radiological features which should enable a confident diagnosis to be made from the chest radiograph alone. Its importance lies in recognising it as a benign lesion and limiting further investigation appropriately.

Investigation of ribs disturbed entrance effect of heat transfer and pressure drop in pin-fin array
Applied Thermal Engineering, 2019Turbine blades are designed to have rather complex internal cooling structures such as ribs and pin-fins, which are installed individually or concurrently in the serpentine channel.

Primary osteosarcomas arising from the rib are very rare. The authors report an 11-year-old boy with a primary fibroblastic osteosarcoma of the rib, who underwent wide excision and reconstruction of the chest wall followed by chemotherapy. He is disease free after a follow up of 24 months. The relevant literature is reviewed briefly.

Thermal behaviors in heat exchanger channel with V-shaped ribs and grooves
Chemical engineering research & design, 2019An experimental work has been conducted to explore the influence of the combined V-rib and chamfered-V-groove vortex generator (VG) on flow and heat transfer behaviors in a heat exchanger channel having a constant heat-flux on the top wall.

Clinical Radiology, 1980
The radiological appearances of seven cases of rib tuberculosis are discussed. The combination of rib destruction and an extrapleural soft tissue opacity in an Asian immigrant makes tuberculosis a highly likely diagnosis. The presence of an associated fluctuant chest wall swelling, enables a diagnosis of tuberculosis to be made with confidence even in ...

Static and fatigue properties of the steel-UHPC lightweight composite bridge deck with large U ribs
Journal of constructional steel research, 2018A lightweight composite deck (LWCD) is a bridge deck system composed of an orthotropic steel deck and an ultra-high performance concrete (UHPC) layer. In this paper, the LWCD was refined with the concept of large U ribs.

1Primary rib tumors are as frequently benign as they are malignant. 2Whether the tumor is benign or malignant is often a difficult decision unless careful and detailed studies are made grossly and microscopically. 3All primary tumors of the ribs should be removed regardless of whether they are thought to be benign or malignant, unless ...

Analysis and design of axially loaded square CFST columns with diagonal ribs
, 2019Diagonal binding ribs, made of thin-walled steel plates with circular openings and welded to the steel tube of a square concrete-filled steel tubular (CFST) column, can improve the composite effect effectively by co-carrying axial compressive forces and ...
