In this work, the process parameters involved in the electrophoretic deposition (EPD) to obtain thin TiN films was studied and optimised. The stability of commercial TiN nanopowder in isopropyl alcohol adding a cationic polymer (polyethylenimine) as dispersant, with different molecular weights, was investigated to determine the kinetics of the deposition and to reach the most efficient EPD process. Cathodic EPD was performed over electro-polished stainless steel substrates. It was found that the provided dispersion when the PEI with the highest molecular weight was added to the suspension, leads to the best deposition behaviour for short times. New flocculation phenomena were described which affect to the sticking factor, and thus to the evolution of the EPD kinetics. As a result of the designed stabilization system, a reliable and versatile EPD method to produce well consolidated nano-TiN coatings at 1200 °C in vacuum atmosphere was described. [less ▲]

BACKGROUND For the screening-based strategy for prevention of perinatal GBS disease, CDC Guidelines as many others recommend use of appropriate transport media (Amies, Stuart, e.g.) and processing of specimen as soon as possible within 1 to 4 days. False negative cultures occur for several causes including lost of GBS viability during transport. Could Lim broth, recommended for the selective enrichment, and Granada tubes be used as transport media for swab? Simulating conditions of routine practice, Lim broth and Granada tubes, were evaluated in vitro as transport media. METHODS Tubes of 3 brands of Lim broth (Becton Dickinson, bioMérieux, Copan) and Granada tubes (bioMérieux) were inoculated with low inocula of 10-100 CFU of GBS. Each type of tubes was incubated at 4°C, room T° (RT) and 35°C. GBS were enumerated from each tube by subculture on blood agar after 1, 2, 3 and 4 days of storage at the different T°. All tests were processed in triplicates with 3 strains of GBS belonging to serotype Ia, III and V. RESULTS No difference of survival was observed between the 3 strains. T° had significant impact on GBS recovery for each type of tubes. At 4°C the viability was hardly sustained along the 4 days. At RT and 35°C, an increase >6 log of the inocula was observed. The increase of GBS density was sustained at least 4 days for the 3 brands of Lim broth. For the Granada broth, such increase was also observed but at day 3 for tubes incubated at 35°C, viability decreased and for some tubes, GBS subcultures were negative at day 3 or 4. CONCLUSION To improve sensitivity of GBS screening cultures, Lim broth could be recommended as a strong transport media and the advisable storage condition would be RT to 35°C up to 4 days. In this way, initiating selective enrichment culture at the time of collection of specimen would provide higher sensitivity even for low density of colonization. Transport at 4°C should be avoided in favour with RT to 35°C. Studies in clinical setting are expected. For Granada tubes, storage at RT was fine but improvement seemed restricted in time at 35°C as there was a loss of viability after 3 days. For Granada tubes, extended evaluation and delimitation of use are needed. [less ▲]

A single fraction of essential oil can often contain hundreds of compounds. Despite of the technical improvements and the enhanced selectivity currently offered by the state-of-the-art gas chromatography (GC) and mass spectrometry (MS) instruments, the complexity of essential oils is frequently underestimated. Comprehensive two-dimensional GC coupled to time-of-flight MS (GC×GC-TOFMS) was used to improve the chemical characterization of ylang-ylang essential oil fractions recently reported in a previous one-dimensional (1D) GC study. Based on both, the enhanced chromatographic separation and the mass spectral deconvolution, 161 individual compounds were identified and labeled as potentially characteristic analytes found in both low and high boiling fractions issued from distillation of mature ylang-ylang flowers. Compared to the most recent full GC-MS characterization, this represents 75 new compounds, essentially consisting of terpenes, terpenoid esters, and alcohols. [less ▲]

The development of mid-infrared equations to predict the milk fatty acid (FA) content of milk allows prompt analysis of large numbers of samples. The first aim was to improve these predictions by comparing 6 statistical approaches. The second one was to validate the new equations using an independent sample set. The calibration set contained 239 spectrally different Belgian milk samples collected for over 2 years from several cows and breeds. FA were quantified by gas chromatography (GC). Statistical approaches tested were 1) partial least squares regression (PLS), 2) PLS and first derivative, 3) PLS and repeatability file (RF), 4) PLS, first derivative and RF, 5) PLS, second derivative, and 6) PLS, second derivative and RF. This last file contained spectra obtained from the same samples using 5 spectrometers. Cross-validation (CV) used 20 groups from the calibration set. Methods were compared using the ratio of the standard deviation of GC values to the standard error of CV (RPD). An external validation permitted a second comparison and was done using 362 samples collected for one year from multiple breeds and cows in Belgium, Ireland, and Scotland. Different RPD values were obtained by the 6 methods. Generally the equations developed using method 4 gave better results suggesting the adaptation of the methodology to the studied FA. It confirms by the obtained validation coefficients of determination. Highest values were observed for the equations with the highest RPD values except for C18:0. The ability to predict FA using method 4 gave superior results to those shown in previous publications. [less ▲]

The residual activity (i.e. coagulating activity of the immobilized enzyme as % of that of the free enzyme) of rennet immobilized by diazotization on porous glass balls was increased from about 11% to 38.3% by adding serum albumin and to 23.7% by adding glutaraldehyde (to replace diazotization) to the binding medium. The serum albumin also increased the stability of the immobilized rennet during storage: after 14 days, 42.2% of its initial activity was retained. Drying the glass balls (for 12 h at 110 deg C) after silanization also improved the stability of the enzyme. The effects of various other factors (e.g. binding medium and binding time) were also studied. As a result of the improvements achieved, industrial application of immobilized rennet is envisaged.

One of the most important activity of agricultural research insititutes concerns the agronomical experiments done under different conditions needing many land observations and valuations to quantify several variables. These observations, although generally accurate, are visually done by the agriculturist technicians and present numerous drawbacks: penibility, weak productivity, numerous labor force, limited sampling … Two feasibility studies lead in our laboratory recently have shown that some of the previous observations, and particularly the counting of the number of wheat ear per m², can be done by color and/or texture image processing for images taken directly in the field with a specific acquisition system. This paper describes the improvements of the previous studies concerning the image acquisition system, and especially the illumination control, and the justification of different hypothesis on the number of classes to detect in an image. The use of a cluster validity index has allowed to prove that 3 classes to determine all the objects in a wheat ear image are not sufficient. A correlation with a study based on the size of the analysis window is currently under investigation to improve the ear detection, which is now of 6%, compared to manual counting done by agriculturist technicians.
