In work the technique of theoretical definition of temperature fields at thermoplastic hardening is presented. As an example results of calculations for unilateral cooling of a large-sized detail of type of a disk of the turbine of gas turbine engines are shown. Comparison of settlement and experimental temperature fi…
In this work the methodology of an estimation of parameters of reliability GTD with a glance sudden failures is presented. By this methodology the analysis of influence of the limit of the geometrical sizes, rotating frequency and disk material density on failure rate is carried out.
Prions are associated with a number of fatal diseases in mammals and heritable phenotypes in yeast. Prions propagate through pathway that involves protein misfolding and aggregation. The mis-folded state is propagated through interactions between misfolded aggregates and normally folded protein monomers. Prion aggrega…
Schools of fish, flocks of birds and other groups of organisms, can move in a highly coordinated fashion despite the fact that each member only experiences its immediate surroundings and there exists no obvious leader. Understanding how the global properties of the group, for example its shape, dynamics and organizati…

\n O desenvolvimento de uma matriz de colágeno associado à gelatina tem potencial como biomaterial devido sua alta biocompatibilidade, capacidade de alterar suas propriedades físico-químicas e estruturais por modificações químicas e a habilidade de formar géis estáveis. Porém, um ponto negativo de sua aplicação está n…
This thesis describes the development of donor-acceptor conjugated copolymer fullerene blends for applications in bulk heterojunction organic solar cells. The characterisation of the optoelectronic properties of the blends as well as the optimisation of such materials into organic photovoltaic (OPV) devices is describ…
UNJUK KERJA LSC TRICARB 2910TR PADA PENGUKURAN RADIOAKTIVITAS TRITIUM DALAM SAMPEL AIR LAUT. Kemampuan LSC menentukan radioaktivitas tritium dalam sampel lingkungan air laut sangat ditentukan oleh besarnya cacah background. Pengukuran yang teliti memerlukan sampel blangko background dengan komposisi cocktail-sampel se…

Telah dipelajari imobilisasi limbah trans-uranium (TRU) pemancar alfa pelarut bekas dengan bahan matriks gelas, keramik, dan polimer untuk mendapatkan bahan yang lebih sesuai. Pengolahan limbah TRU dengan bahan gelas borosilik…
Analysis of. physical processes that may cause the fragility and destruction of the lava-like fuel contain-ing materials (FCM) of 4-th unit of Chernobyl Nuclear Plant (ChNP) has been carried out. The following pro-cesses are considered: influence of electric fields aris-ing in medium with incorporated radio-nuclides,…

Telah dilakukan pengkajian unjuk kerja Near Surfase Disposal (NSD) untuk komponen Lining (lapisan) pada fasilitas Demoplant (DP) Disposal. Analisis unjuk kerja komponen lining pada fasilitas demoplant NSD berdasarkan perangkat lunak…
This thesis is a part of the KYT-project which studies the safety of the disposal canister for spent nuclear fuel in Finland. The current plan is to encapsulate the spent nuclear fuel elements into a canister with a cast iron insert and a copper overpack. The canister is the primary barrier isolating the nuclear waste…
Abstract Biopolymers, such as poly-3-hydroxy-butyrate (P(3HB)) are produced as a carbon store in an array of organisms and exhibit characteristics which are similar to oil-derived plastics, yet have the added advantages of biodegradability and biocompatibility. Despite these advantages, P(3HB) production is currently…
Chiral skyrmion states exist in non - centrosymmetric magnetic crystals as a consequence of the asymmetric exchange Dzyaloshinskii-Moriya interactions that destroy the homogeneous magnetic state and generally lead to twisted incommensurate magnetic spin-structures. Recently, skyrmion lattices and free skyrmions in mag…
Graphene extraordinary strength, stiffness and lightness have generated great expectations towards its application in flexible electronics and as mechanical reinforcement agent. However, the presence of lattice defects, unavoidable in sheets obtained by scalable routes, might degrade its mechanical properties. Here we…
Nanoscale cellulose particles are popping up in a dizzying number of applications. But despite their high commercial potential, investment in large-volume uses of the materials is low. Uncertainties related to the environmental, health, and safety aspects of the materials could also hinder commercialization of these p…
ZionSolutions is in the process of decommissioning the Zion Nuclear Power Plant. The site contains two reactor Containment Buildings, a Fuel Building, an Auxiliary Building, and a Turbine Building that may be contaminated. The current decommissioning plan involves removing all above grade structures to a depth of 3 fe…

We report the growth temperature dependence of the properties of the group-IV-based ferromagnetic semiconductor Ge1-xFex films (x = 6.5% and 10.5%), including the lattice constant, Curie temperature (TC), and Fe-atom locations. While TC strongly depends on the growth temperature, we find a universal relationship betwe…
Laser welding of wrought magnesium alloy has been investigated through experimentation and simulation. Laser butt welds and laser lap welds were performed on 2.0 mm thick magnesium alloy AZ31 plates using a 1 kW fiber laser and shielded with argon gas. The effects of laser power and welding speed on weld geometry and…
