Otimização de design do duto ramificado em forma de T com escoamento de fluido newtoniano e paredes impermeáveis [PDF]

open access: yes, 2018
Este artigo apresenta os resultados de escoamentos em dutos em forma de “T”. O problema consiste em encontrar as resistências ao escoamento em estruturas tridimensionais (3D) cujos sistemas têm diferentes relações homotética entre tamanhos (diâmetros e ...

New Construction Laws

open access: yesInternational Journal of Public Administration, Management and Economic Development
The new Construction Act became the object of interest of many lawyers and representatives of towns and municipalities. Despite many amendments, the original Construction Act is outdated, cumbersome and inflexible, and along with it, the Act on Spatial Planning and Amendments to certain Acts is changing.

Programmable In‐Situ Interactions Between Resins and Photopolymerized Structures for Seamlessly Integrated Optical Manufacturing of Microlenses

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...

Construction Law and Consumer Law

open access: yes, 2017
In a building construction operation, two sets of rules, which are construction law and consumer law,are superimposed to bring a level of protection to the consumer purchaser of real estate. Correlatively,they generate many obligations for the professionals.

External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

open access: yesAdvanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.
