This chapter examines linear viscoelasticity, which obeys Boltzmann’s superposition principle. Non-linear viscoelasticity has a larger mathematical framework in which linear components of strain (or stress) are the firm term of the Volterra series. The chapter focuses on linear viscoelasticity. In simple examples adop…
more specifically in CR -Center of Radiopharmacy that conducts research and processing of radiopharmaceuticals such as 99 Mo, 131 I, 123 I, 67 Ga, 201 Tl, 18 F, 177 Lu and 153 Sm for use in nuclear medicine. The radioisotopes are produced on industrial scale and the facility was designed to meet the standards of radia…
\n A reação entre resinas epóxi e polialquileno glicóis gera um aduto de elevado peso molecular que pode ter aplicações em diferentes segmentos, tais como polímeros usados na composição base de fluidos de têmpera, viscosificantes para lubrificantes e desemulsificantes de petróleo. As condições envolvendo a formação de…
Stability and electronic properties of atomic layers of GaN are investigated in the framework of the van der Waals-density functional theory. We find that the ground state of the layered GaN is a planar graphene-like configuration rather than a buckled bulk-like configuration. Application of an external perpendicular…

En el campo de la Ingeniería Civil, existe una búsqueda permanente de mejorar las características de materiales de matrices cementicias así como la aplicación de distintos tipos de fibras para su refuerzo, particularmente desde que se prohibió el empleo de amianto. La aplicación de fibras sintéticas es parte de estas…
Dalam produksi radioisotop 99Mo akan ditimbulkan limbah radioaktif yang mengandung campuran uranium dan hasil belah. Pengolahan dilakukan untuk memisahkan uranium dari hasil belah menggunakan resin penukar anion. Resin penukar anion akan selektif mengikat uranium dalam bentuk uranium kompleks. Telah dilakukan peneliti…

This work suggests the replacement of commercial silica by silica obtained from rice husk as alternative source for obtaining lithium disilicate material that can be used in dental application. The lithium disilicate as dental material is a glass-ceramic that has good mechanical properties and chemical stability. For…

The extracellular matrix (ECM) is highly dynamic; understanding its biochemical and mechanical properties is necessary for successful tissue regeneration. Magnetic Resonance Imaging (MRI) has been used as a tool to investigate the magnetic relaxation response of water in the ECM by measuring the changes in spin-lattic…
Most diesel engines require diesel particulate filter (DPF) systems to meet increasingly stringent emissions regulations. To develop an effective thermal management system for preventing the failure of a DPF system caused by the thermal runaway, it is important to investigate the heat release characteristics and the o…
[ES] La sensibilidad a la polarización es uno de los mayores problemas en microfotónica, ya que el estado de la polarización cambia aleatoriamente en la fibra óptica. Esquemas de diversidad en polarización deben ser implementados para evitar un control externo de la polarización, y conseguir un mismo estado de polariz…
The neutron experiment (NUEX) was a common diagnostic on nuclear device tests conducted at the Nevada Test Site (NTS). In these experiments neutrons from a device pass up a collimated line of site, and in the case of a Faraday cup (FC) NUEX, the neutrons pass through a thin CH2 foil. Some of these neutrons interact wi…

Until now in Mielnik on the Bug River residual clays deposited on the chalky limestone of the Upper Cretaceous period have been included in the Eocene. However, lying on top of them quartz-glauconitic sands containing phosphorites belong to the Oligocene. Radiometric dating of glauconite from sandy-glauconitic series…
This chapter describes the most widely used actuator principles in microrobotics: piezoelectric, electrostatic, thermal, shape-memory alloy and electro-active polymer actuators. The most widely used actuators in microrobotics are undoubtedly actuators based on piezoelectric ceramics. The chapter mainly focuses on piez…
Abstract : Studies of reaction time are reported for temperatures from -50 degrees to +117 degrees F. The following conclusions apply to simple discrimination and to choice reaction times within the range of conditions examined. The conclusions should not be applied to speed of other performances. (a) Reaction time do…
Underwater supramolecular velcro exhibiting strong and reversible adhesion was achieved using a synthetic ultrahigh-affinity host–guest binding pair of cucurbit[7]uril (CB[7]) and aminomethylferrocene (Fc). In their Communication on page 3140 ff., K. Kim et al. show that the CB[7] loops and Fc hooks anchored on differ…
