The purpose of paper "Le biomimétisme: Une source d'inspiration pour le management des ressources humaines d’une entreprise de tourisme" is to examine how tourism companies can draw inspiration from the animal world, and in particular from the biomimicry of ants, in order to improve theirs human resources management. Indeed, the social system of insects has certain characteristics, such as an enhanced communication capacity and a collective intelligence, that are required for a proper management of the human resources of tourist companies that have a sustainability perspective.

These geochemical traits point to the adakite-like affinity for Pertek andesite-dacite porphyries, however, they present some geochemical characteristics of both oceanic slab-derived and continental crust-derived adakites and show a dual character. Enrichment in K2 O, Th, Rb, and Hf in these adakitic porphyries is mostly associated with the crust-derived terrigenous sediments during active subduction, before the Early Miocene.

Three plastic scintillators of 4.5 cm diameter and 2.5-cm length were fabricated for comparison with commercial plastic scintillators using polymerization of the styrene monomer 2.5-diphenyloxazole (PPO) and 1,4-bis benzene (POPOP). Their maximum emission wavelengths were determined at 426.06 nm, 426.06 nm, and 425.00 nm with a standard error of 0.2% using a Varian spectrophotometer (Agilent, Santa Clara, CA, USA).

Geography can be described as a field of science which is the study of the Earth’s physical features, people, as well as the relationships between people and their environment. Based on collecting and analyzing materials from various sources, the paper analyze the characteristics of major branches in the new trend of geography. In addition, as a basis for the above analysis, we also outline the history of geography and present the traditional and modern methods in geographical research.

Pyruvate dehydrogenase kinase (PDK) is the primary regulator of flux through the mitochondrial pyruvate dehy-drogenase complex (PDC).Analysis of the primary amino-acid sequences of PDK from various sources reveals that these enzymes include the five domains characteristic of prokaryotic two-component His-kinases, despite the fact that PDKexclusivelyphosphorylates Ser residues in theE1a subunit of the PDC.This seeming contradiction might be resolved if the PDK-catalyzed reaction employed a phos-pho-His intermediate....

They are more frequent events than accidents and their causes may potentially result in an accident under slightly different circumstances.

Characteristic cohomology classes, defined in modulo 2 coefficients by Stiefel [26] and Whitney [28] and with integral coefficients by Pontrjagin [24], make up the primary source of first-order invariants of smooth manifolds. When their utility was first recognized, it became an obvious goal to study the ways in which they admitted extensions to other categories, such as the categories of topological or PL manifolds; perhaps a clean description of characteristic classes for simplicial complexes could even give useful computational techniques.

Stem Cell Biology Stem Cell Biology: Introduction Stem cell biology is a relatively new field that explores the characteristics and possible clinical applications of the different types of pluripotential cells that serve as the progenitors of more differentiated cell types. In addition to potential therapeutic applications (Chap. 67), patient-derived stem cells can also provide disease models and a means to test drug effectiveness.

A zener diode is a special diode that p is optimized for operation in the g breakdown region. ZENER DIODE CIRCUIT The zener diode is typically connected reverse biased, in parallel with the load. Resistor Rs limits current to zener.
