Les pili de type IV (PT4), certainement les organelles les plus répandues des bactéries à Gram-négatif, sont des machineries à multiples fonctions qui jouent un rôle crucial dans la pathogenèse de nombreux pathogènes humains, notamment notre modèle Neisseria meningitidis. L’assemblage des PT4 nécessite une machinerie…
Ce travail de thèse porte sur le contrôle de santé intégré par émission acoustique desmatériaux composites stratifiés et sandwichs. Le capteur d’EA est d’une part implanté dans lamasse du matériau et d’autre part collé à la surface de ce dernier. Une première étude estconsacrée à l’étude de l’influence de l’implant pi…

Volume is indexed by Thomson Reuters CPCI-S (WoS).Abrasive machining is one kind of old technology, but it has a far-reaching impact on a broad spectrum of industries. In particular modern manufacturing, there is an ever increasing demand of advanced abrasive technology and other precision abrasive technology. The col…
INTRODUÇÃO:A síndrome de Alport é uma doença hereditária, predominantemente ligada ao X, caracterizada por surdez neurossensorial e insuficiência renal progressivas, bem como alterações oculares envolvendo a córnea, o cristalino e a retina.Mutações em genes que codificam o colágeno tipo IV, presente nas membranas basa…

Hydrotropes are amphiphilic molecules that are too small to spontaneously\nform equilibrium structures in aqueous solutions, but form dynamic, noncovalent\nassemblies, referred to as clusters. In the presence of a hydrophobic compound,\nthese clusters seem to get stabilized leading to the formation of long-lived,\nhig…

In fiscal year (FY) 2012, Argonne National Laboratory (Argonne) developed a method for cleaning up uranium from a Subcritical Hybrid Intense Neutron Emitter (SHINE) Target Solution (STS) using a sulfate-to-nitrate conversion step (Bowers and Vandegrift 2013) followed by a UREX (uranium recovery by extraction) process…
Protein dynamics have controversially been proposed to be at the heart of enzyme catalysis, but identification and analysis of dynamical effects in enzyme-catalyzed reactions have proved very challenging. Here, we tackle this question by comparing an enzyme with its heavy ((15)N, (13)C, (2)H substituted) counterpart,…
Design and Synthesis of π-Electronic Covalent Organic FrameworksCovalent Organic Frameworks (COFs) are a class of crystalline porous polymers that enable elaborate integration of organic building blocks into ordered structures with atomic precision.Because they are composed of lightweight elements linked by strong cov…
Bu çalışmada öncelikle; nötrinolar ve kozmoloji açısından önemi, Einstein alan denklemleri, enerji-momentum tensörü ve türleri özetlendi.Daha sonra, evrenin evrimininde birçok döneminde etkin rol oynadığına inanılan kozmik nötrinolar başta olmak üzere, ideal akışkan, kütlesiz skaler alan, ısı akısı ve kozmik sicim içe…
Automation and processing software was developed for interpretation of the results of reactor experiments on tritium release study. Tritium was continuously generated as a result of nuclear reaction of lithium-6 and thermal neutrons under variable thermal impacts on lithium metatitanate. Main gas release parameters, w…
Within a framework of approaching the effective media and Drude-Lorenz Model, the calculations of the optical characteristics, which include the refraction index and absorbability in the spectral region below the end of band-to band absorption, assemblies of silicon nano crystals with various form and space-filling fa…
A linear behavior of an decrease of number of Si-C-bonds in homogeneous layers of silicon carbide in silicon with an increase of duration of isothermal (1200С) annealing evident about independence of the SiC decay rate on the depth of the oxidation front. The shift of the minimum of the peak of IR transmission up to…
Several reactivity control system design options are explored in order to satisfy shutdown margin (SDM) requirements in a high conversion BWRs operating in Th-233U fuel cycle (Th-RBWR). The studied has an axially heterogeneous fuel assembly structure with a single fissile zone sandwiched between two fertile blanket zo…
Наведено результати досліджень із реагентної переробки відпрацьованих свинцево-кадмієвих га-льванічних елементів і акумуляторів, які слугують вторинною сировиною для електротехнічної про-мисловості. Розглянуто особливості технологіч-ного проектування, екологічні й економічні аспек-ти переробки. Проаналізовані стадії п…
