A Variation of the Components’ Separation Technique that Preserves the Semilunaris for Treatment of Abdominal Wall Deformities

The variation of the components’ separation technique, which uses the anterior rectus sheath and the release of the oblique muscles, proved to be effective in tension reduction. This paper aimed to present the initial experience using a variation that preserves semilunaris through the incision of the lateral aspect of the rectus sheath. All of the 12 patients presented an abdominal wall defect that included incisional hernia, peritoneostomy, lateral implantation of the rectus muscle, and defect secondary to TRAM flap. The separation was done in the following stages: stage 1—anterior rectus sheath and stage 2—external oblique muscles. From the 12 patients, three presented early complications: seroma (n = 2) and epitheliolysis (n = 1). There were no recurrences or other late complications (48 months follow-up period). The separation of the anterior rectus sheath, and incision in the lateral recess to undermine the oblique muscles, allowed the treatment of abdominal wall defects, without late complications.

Production, characterization and application of ternary phase diagrams for the purification of biodiesel produced from tropical almond seed oil

This study presents the application of ternary phase diagrams to tropical almond biodiesel components separation and purification at two temperatures. The seed oil was extracted mechanically and alkaline transesterified to produce biodiesel. The oil and biodiesel were characterized using standard methods. Tie lines and binodal solubility curve data were determined using modified cloud point titration procedures. Gas chromatographic method was employed in the analysis of the phase compositions. The mixture of biodiesel, methanol and glycerol were investigated at 20 °C, 30 °C and withdrawal times of 2 to 32 minutes at 2 minutes intervals. Distribution coefficient, K and solvent selectivity, S analysis were performed. Results obtained showed that S > 1 indicating the ability of methanol to promote phase separation and purification. K < 1 implying that there was lower quantities of methanol solubilized in the biodiesel phase. The ternary phase diagrams provided the means of predicting the components distribution. Keywords: Production, Characterization, Tropical Almond Biodiesel, Purification, Ternary Phase Diagram

Geographical query reformulation using a geographical adjacency taxonomy builder and word senses

Purpose Geographical query formulation is one of the key difficulties for users in search engines. The purpose of this study is to improve geographical search by proposing a novel geographical query reformulation (GQR) technique using a geographical taxonomy and word senses. Design/methodology/approach This work introduces an approach for GQR, which combines a method of query components separation that uses GeoNames, a technique for reformulating these components using WordNet and a geographic taxonomy constructed using the latent semantic analysis method. Findings The proposed approach was compared to two methods from the literature, using the mean average precision (MAP) and the precision at 20 documents (P@20). The experimental results show that it outperforms the other techniques by 15.73% to 31.21% in terms of P@20 and by 17.81% to 35.52% in terms of MAP. Research limitations/implications According to the experimental results, the best created taxonomy using the geographical adjacency taxonomy builder contains 7.67% of incorrect links. This paper believes that using a very big amount of data for taxonomy building can give better results. Thus, in future work, this paper intends to apply the approach in a big data context. Originality/value Despite this, the reformulation of geographical queries using the new proposed approach considerably improves the precision of queries and retrieves relevant documents that were not retrieved using the original queries. The strengths of the technique lie in the facts of reformulating both thematic and spatial entities and replacing the spatial entity of the query with terms that explain the intent of the query more precisely using a geographical taxonomy.

The concept of 3D ECT system with increased border area sensitivity for crystallization processes diagnosis

Purpose Crystallization is the process widely used for components separation and solids purification. The systems for crystallization process evaluation applied so far, involve numerous non-invasive tomographic measurement techniques which suffers from some reported problems. The purpose of this paper is to show the abilities of three-dimensional Electrical Capacitance Tomography (3D ECT) in the context of non-invasive and non-intrusive visualization of crystallization processes. Multiple aspects and problems of ECT imaging, as well as the computer model design to work with the high relative permittivity liquids, have been pointed out. Design/methodology/approach To design the most efficient (from a mechanical and electrical point of view) 3D ECT sensor structure, the high-precise impedance meter was applied. The three types of sensor were designed, built, and tested. To meet the new concept requirements, the dedicated ECT device has been constructed. Findings It has been shown that the ECT technique can be applied to the diagnosis of crystallization. The crystals distribution can be identified using this technique. The achieved measurement resolution allows detecting the localization of crystals. The usage of stabilized electrodes improves the sensitivity of the sensor and provides the images better suitable for further analysis. Originality/value The dedicated 3D ECT sensor construction has been proposed to increase its sensitivity in the border area, where the crystals grow. Regarding this feature, some new algorithms for the potential field distribution and the sensitivity matrix calculation have been developed. The adaptation of the iterative 3D image reconstruction process has also been described.
