Sophorolipids (SLs), produced by Candida bombicola, are of interest as potential replacements for hazardous commercial surfactants. For the first time, a series of molecularly edited SLs with ethyl (EE), n-hexyl (HE), and n-decyl (DE) esters were evaluated at an oil (almond oil)-water interface for their ability to reduce interfacial tension (IFT) and generate stable emulsions. An increase in t...

We measured interfacial tensions (IFT) of aqueous alkyl polyglucoside (APG) systems formulated with sorbitan ester-type cosurfactants against n-octane. The study focused on low to ultralow IFT systems which are relevant for enhanced oil recovery (EOR). In addition, we measured equilibrium adsorption concentrations of these surfactants and cosurfactants onto kaolinite clay, commonly found in oil...

This paper studies the possible application of Iterative Feedback Tuning (IFT) to the paper machine cross-directional (CD) control. Although the CD control is naturally a multiinput-multi-output (MIMO) problem, by enforcing the circulant assumption, IFT for CD control is as simple as the single-input-single-output (SISO) case, i.e. only one gradient experiment is needed for estimating the gradi...

Cilia are specialized structures that not only play diverse roles in cell motility but also transmit signals to the cytoplasm and nucleus to control gene expression, cell function, animal development, and behavior. Cilia are assembled and maintained by the intraflagellar transport (IFT) machinery, which coordinates rapid, bidirectional transport between the cell body and the distal tip of the c...

Abstract. The watershed transform and the morphological reconstruction are two of the most important operators for image segmentation in the framework of mathematical morphology. In many situations, the segmentation requires the classical watershed transform of a reconstructed image. In this paper, we introduce the IFT-watershed from gray scale marker a method to compute at same time, the recon...

Editor’s key points † Bispectral index (BIS) monitoring is commonly used to monitor depth of anaesthesia. † The authors studied parturients in whom standard techniques were used for general anaesthesia for Caesarean section. † The isolated forearm test was used to study the ability of the BIS to detect consciousness. † BIS values below 60 were commonly associated with IFT responses, particularl...

The aim of this study was to evaluate the effect of intrafollicular treatment (IFT) with different doses of luteinising hormone. Experimental heifers were treated with a single deslorelin implant to desensitise gonadotroph cells of the pituitary gland. Thereafter, follicular development was stimulated by exogenous FSH treatment. Intrafollicular treatment with 10, 5, 1 and 0.01 μg LH was perform...

In this paper we study the segmentation of coronary arteries from bidimensional echocardiography simulated images (phantoms) using Fuzzy Connectedness concepts implemented using Image Foresting Transform (IFT). This approach transforms the image into an oriented and weighted graph; therewith a graph-based algorithm can be applied to process the image segmentation. In echocardiographic scenario,...

Cilia play diverse roles in vertebrate and invertebrate sensory neurons. We show that a mutation of the zebrafish oval (ovl) locus affects a component of the ciliary transport (IFT) mechanism, the IFT88 polypeptide. In mutant retina, cilia are generated but not maintained, producing the absence of photoreceptor outer segments. A loss of cilia also occurs in auditory hair cells and olfactory sen...

Intraflagellar transport (IFT) is a rapid movement of multi-subunit protein particles along flagellar microtubules and is required for assembly and maintenance of eukaryotic flagella. We cloned and sequenced a Chlamydomonas cDNA encoding the IFT88 subunit of the IFT particle and identified a Chlamydomonas insertional mutant that is missing this gene. The phenotype of this mutant is normal excep...
