ON THE DETERMINATION OF THE SHAPE-TYPE OF PARTICLES
Image Analysis & Stereology, 2011 Based on observations on similar-looking randomly deformed particles inference is made about the original common shape-type of these particles by means of statistical tests.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The distribution of settling velocity of non-spherical mineral particles [PDF]
Acta Montanistica Slovaca, 2005 The settling velocity is an independent variable of the hydraulic separation performed for instance by means of jigs. Therefore, the settling velocity characterizes the material forwarded to the separation process.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
FEBS Letters, EarlyView.Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Shape oscillations of particle-coated bubbles and directional particle expulsion [PDF]
, 2016 Bubbles stabilised by colloidal particles can find applications in advanced materials, catalysis and drug delivery. For applications in controlled release, it is desirable to remove the particles from the interface in a programmable fashion.

ELECTRODEPOSITION OF COPPER POWDER FROM MIXTURE SULPHATE –CHLORIDE ACIDIC SOLUTION
Iraqi Journal for Mechanical and Materials Engineering, 2018 This paper studies the preparation of Copper powder from Copper Sulphate aqueous solution(CuSO4.5H2O), sulfuric acid (H2SO4) and copper chloride (CuCl2.2H2O)by using the process of electro-deposition.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Calculating Shape Factors from Particle Sizing Data
, 1996 It is well established that particle size and shape substantially influence the bulk properties of powdered materials. Although these characteristics are closely interrelated, the tendency has been to analyse the particle size independently from particle
