In eukaryotes, translation initiation is guided by up to twelve protein initiation factors (eIFs) and begins with the formation of the 43S pre-initiation complex (PIC) composed of the small ribosomal subunit (40S), eIF2.GTP/Met-tRNAi Met ternary complex, and eIFs 1, 1A, 3 and 5. The 43S PIC subsequently interacts with…

Diese Arbeit beschäftigt sich mit der Darstellung des synthetischen Polypeptids Poly(gamma-benzyl-L-glutamat) (PBLG), der Synthese von PBLG-haltigen Blockcopolymeren und ihren Selbstorganisationsphänomen. Synthetische Polypeptide sowie auf solchen basierende Blockcopolymere dienen als Modellpolymere zur Nachahmung von…
The deterministic Landau-Lifshitz-Gilbert equation has been used to investigate the nonlinear dynamics of magnetization and the specific loss power in magnetic nanoparticles with uniaxial anisotropy driven by a rotating magnetic field, generalizing the results obtained for the isotropic case found in [P. F. de Chatel,…
This book is about the relationship between structure size and crack propagation during mechanical loadings. It is commonly accepted that there is a size effect on the nominal resistance of quasi-brittle materials such as concrete. This effect must be taken into account when designing the ultimate behaviour of concret…
"Ti6Al4V was implanted by oxygen plasma based ion implantation at pulsed negative voltages of 50 kV with a\nfluence of 4×1017 O/cm2. The implanting temperature of below 180 °C was controlled by an oil cooling working\ntable. Subsequent annealing was applied the implanted samples in vacuum at 600 °C, 650 °C and 700 °C,…
Novel ZnS quantum dots (QDs) and ZnS quantum flakes (QFs) were successfully prepared with graphene nanosheets (GNs) as a special template, and two unique heterostructures of ZnS/GNs were also obtained. Due to the structuredirecting template effect of GNs, the as-synthesized ZnS with different morphologies, dots or fla…
Materials Science The physical properties of a substrate are known to affect the fate of stem cells by influencing whether they spread out and remain potent, or whether they undergo differentiation. In vivo, for example, human epidermal stem cells can adhere to the extracellular matrix (ECM), which
L’utilité des équations d’état dans le domaine de polymères a été démontrée depuis de nombreuses années, notamment les équations d’état cubiques. Leur pouvoir prédictif reste cependant limité. De nouvelles équations d’état, basées sur des principes de mécanique statistique, ont été développées, et sont maintenant de p…
In the last few years, polymer carbon nanotubes (CNTs) nanocomposites foams have received increasing attention due to their potential applications in electrostatic dissipation (ESD) and in electromagnetic interferences (EMI) shielding. To be efficient, these foams must exhibit appropriate electrical conductivity (> 1…
Im ersten Teil dieser Arbeit wurde die Beladung des Trägermaterials Polystyren mit unterschiedlich polaren Wirkstoffen mittels eines Lösungsmittelverdampfungsprozesses (LVP) untersucht. Hierbei sollten Parameter identifiziert und untersucht werden, mit denen sich die Beladung des Trägermaterials kontrollieren sowie di…
Transparent electrodes using carbon nanotube (CNT) have recently been studied as potential replacements for conventional indium tin oxide (ITO). In this work, CNT and ITO coated polyethylene terephthalate samples were prepared and studied. The degree of cohesion is dependent on the drying conditions. To explore affect…
This study was conducted to assess changes in soil properties of a soil that received a one-time application (360 Mg ha−1) of fluidized bed combustion material (FBCM) 23 years earlier. Soil samples were taken at three depths (0–10, 10–20, and 20–30 cm). Samples were also collected from an adjacent field with the same…
The Y-12 National Security Complex is playing a role in the U.S. High Performance Research Reactor (USHPRR) Conversion program sponsored by the U.S. National Nuclear Security Administration's Office of Global Threat Reduction. The USHPRR program has a goal of converting remaining U.S. reactors that continue to use hig…
Abstract We demonstrate that a magnetic tunnel structure irradiated by microwaves can generate a typical voltage signal due to the rectification effect. We performed measurements in current-in-plane geometry when a current flows parallel to the interfaces in the structure. The value of the microwave-induced voltage st…
Self-assembling molecules are central to a plethora of processes found in nature, biotechnology and even disease. The importance of the non-covalent interaction of monomers to the formation of fibrillar assemblies is evident in the repeated use of this mechanism throughout nature, from essential cellular processes suc…
While several organic compounds were detected in the vapor samples used in the reenactment of the preparation of mounts from the extracts of nuclear grade high-efficiency particulate air filter fiberglass samples, the most significant species present in the samples were methylene chloride, phenol, phenol-d6, and 2-flu…
The Andreev reflection spectra were studied for the first time in the magnetic superconductor Dy0.6Y0.4Rh3.85Ru0.15B4. It is found that an external magnetic field (up to 0.7 Hc2) is a strong stimulator of superconductivity in contrast with traditional superconductors with a singlet pairing. The ratio 2Δ/kBTc \approx 4…
This paper describes an active power filter (APF) control strategy, which eliminates harmonics and compensates reactive power in a three-phase four-wire power system supplying non-linear unbalanced loads in the presence of non-linear non-stationary currents. Empirical Mode Decomposition (EMD) technique developed as pa…
This paper analyzes the electrochemical response of the corrosive phenomenon caused by the entry of the chloride ion and, later, with the application of cathodic protection on steel embedded in mortar activated slag (AAS) and ordinary Type I Portland (OPC). The electrochemical study was performed by using half-cell po…
