Bacterial Hydrodynamics [PDF]

Annual Review of Fluid Mechanics, 2016
Bacteria predate plants and animals by billions of years. Today, they are the world's smallest cells yet they represent the bulk of the world's biomass, and the main reservoir of nutrients for higher organisms. Most bacteria can move on their own, and the majority of motile bacteria are able to swim in viscous fluids using slender helical appendages ...

Risk Analysis of Ship Collision and Modelling of Oil Spill Trajectory Study Case : Dumai Port

Kapal
Dumai Port is a significant natural port in Sumatra, characterized by deep waters sheltered from waves and calm currents due to surrounding islands. It plays a crucial role in the export of Crude Palm Oil (CPO) and the operations of Pertamina's RU II ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

239/240Pu Dispersion Modeling for Emergencies During Nuclear Power Plant Operations in Malaysia

Ilmu Kelautan, 2022
The East Coast of Johor in Malaysia is a strategic area as a candidate site for nuclear power plants. Its location is near coastal area and is therefore convenient to use seawater as a source of cooling for power plants.

On the Hydrodynamics of Crystal Clustering [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2019
The formation of crystal clusters may influence the mechanical behaviour of magmas. However whether clusters form largely from physical contact in a mobile state during sedimentation and stirring, or require residence in a crystal mush is not well understood.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
