Thus, a new model for finite-element simulations based on two transport mechanisms is applied. The mesh is split into two regions, where channels with a high diffusion coefficient lead through a bulk ...

The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules. Passive transport can only move molecules from a region of higher concentration to ...

diffusion and osmosis; osmotic pressure, root pressure; turgidity and flaccidity; plasmolysis and deplasmolysis; the absorption of water and minerals; active and passive transport (in brief); The ...

The Roads and Transport Authority (RTA) took to their social media account to announce the delay. The authority said that a bus service has been provided to transport passengers from the station.

The project aims to investigate and implement active and passive controls to reduce pedestrian exposure of air pollutants created from vehicle emissions. This will involve the monitoring and modelling ...

Diffusion and osmosis are both passive transport processes, meaning they require no energy input to move substances. Both processes are essential to the proper functioning of biological processes ...

By contrast, material transport in bacteria is often short-ranged and limited by diffusion. Here, we report a unique form of actively regulated long-range directed material transport in structured ...

Object manipulation in such cases typically involves transport, pick-and-place and assembly of objects ... Here, we show autonomous position control of passive particles floating at the air-water ...

Different types of solutions exhibiting osmosis are ... membrane by special proteins called transport proteins or permeases. This process of forced diffusion of certain substances through ...
