Gas turbine combustor insensitive to compressor outlet distortion [PDF]

open access: yes, 1970
Short-length annular combustor for turbojet engines eliminates change of exit temperature profile. Individual scoops of full annular height control air distribution so that shifts in the radial velocity profile of air entering the combustor will not ...

Development of a Synthetic Hydrogel to Foster Microvascularization of an Endometriosis Microphysiological System

open access: yesAdvanced Healthcare Materials, EarlyView.
ABSTRACT The ascent of novel alternative methods in drug development spotlights the dual needs for improved biological fidelity to in vivo, along with reproducibility, especially in regulatory applications. The need for pre‐clinical models of patient‐derived endometriosis lesions motivates the development of a vascularizable, completely synthetic ...

Indirect Lobbying and Media Bias [PDF]

open access: yes
In this paper, we study a model where voters have state-contingent preferences over policies and lobbies engage in influence activities to affect the information that a media outlet collects on the state of the world.

Bioengineered 3D hPSC‐Cholangiocyte Ducts With Physiological Signals for Biliary Disease Modeling

open access: yesAdvanced Healthcare Materials, EarlyView.
Tian and colleagues generated a bioengineered bile duct from human pluripotent stem cell (hPSC)‐derived intrahepatic cholangiocytes within a high‐throughput, 384‐well platform to systematically examine the influence of biliary physiological signals including fluid flow, stromal cells and bile acids, and models intrahepatic biliary disease progression ...

STUDY ON STRUCTURE INFLUENCE FACTOR OF DIESEL ENGINE EXHAUST MANIFOLD THERMAL LOAD

open access: yesJixie qiangdu, 2016
Exhaust manifold is a main heated component of engine,which has poor working conditions. High levels of thermal load can lead to deformation even cracking,which affect its normal working and reliability and durability.

Valve designed with elastic seat [PDF]

open access: yes, 1965
Absolute valve closure is accomplished by a machined valve with an axially annular channel which changes the outlet passage into a thin tubular elastic seat member with a retainer backup ring.

A New 3D Colon on a Chip to Decipher the Influence of Mechanical Forces on the Physiological Cellular Ecosystem

open access: yesAdvanced Healthcare Materials, EarlyView.
To dissect how mechanical forces influence intestinal physiology, we developed a stretchable 3D colon‐on‐chip that integrates tunable topography, stiffness and peristalsis‐like motion within a physiologically relevant microenvironment. We showed that stretching is a dominant factor governing epithelial behavior, markedly enhancing proliferation and ...
