A Simplified Technique for the Fabrication of Esthetic and Functional Space Maintainers in Pediatric Dentistry

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Introduction Premature loss of primary molars remains a frequent clinical problem in pediatric dentistry and may lead to space loss, occlusal disturbances, and the need for future orthodontic intervention. Conventional space maintainers, such as the band‐and‐loop appliance, are effective in preserving arch length but do not restore occlusal ...

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean

Journal of Fish Biology, EarlyView.
Abstract The grey reef shark Carcharhinus amblyrhynchos is one of the most frequently encountered reef‐associated shark species in the Maldives, yet very little is known about its local size structure or population dynamics. This study provides new insights into two aggregations of C.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Do robots boost productivity? A quantitative meta‐study

Journal of Economic Surveys, EarlyView.
ABSTRACT This meta‐study analyzes the productivity effects of industrial robots. More than 1800 estimates from 85 primary studies are collected. The meta‐analytic evidence suggests that robotization has so far provided, at best, a small boost to productivity. There is strong evidence of publication bias in the positive direction.

EFFECT OF WELDING SEQUENCE AND LINE HEATING ON FATIGUE STRENGTH FOR WELDED STRUCTURES

EFFECT OF WELDING SEQUENCE AND LINE HEATING ON FATIGUE STRENGTH FOR WELDED STRUCTURES
Fatigue strength of sound welded joints is affected not only by stress concentration due to structural discontinuity and local shape of weld toe but also by residual stresses. It is known that welding sequence makes the change of welding residual stress distribution.
