Calculation of the Overlap Function and Associated Error of an Elastic Lidar or a Ceilometer: Cross-Comparison with a Cooperative Overlap-Corrected System.

This paper establishes the relationship between the signal of a lidar system corrected for the incomplete overlap effect and the signal of another lidar system or a ceilometer for which the overlap function is unknown. Simple mathematical relationships permit the estimation of the overlap function of the second system as well as the associated error. Several overlap functions have been retrieved with this method over a period of 1.

Influence of Calcium Scaling on Corrosion Behavior of Steel and Aluminum Alloys.

Calcium scaling is a serious problem encountered in the oil and gas industry because it is common that brines produced alongside oil and gas exhibit high concentrations of calcium ions, among others, which is expensive to remedy. The precipitation of calcium salts on the internal wall of the pipelines may occur because of the physical and chemical changes as fluids are produced from downhole to surface facilities. Although different researchers have address scaling and corrosion in the oil and gas industry, there are few reports in the literature relating the corrosion and scaling phenomena simultaneously.

Allele diversity of the killer cell immunoglobulin-like receptors KIR3DL1/S1 and the combination with their HLA ligands in Mexican Mestizos from Mexico City.

Killer cell immunoglobulin-like receptors (KIRs), expressed on Natural Killer (NK) cells, activate/inhibit NK cell function through interactions with their HLA-A, B and C ligands. KIR3DL1 is one of the most polymorphic genes and its effect varies depending on the interaction of the specific allotype with its Bw4 ligand. We investigated the allelic diversity of KIR3DL1/S1 using sequence based typing and we typed as well, their Bw4 ligands in Mexican Mestizos of Mexico City.
