U ovome radu projektirani su i simulacijski ispitani PI regulator struje armature i PI regulator brzine vrtnje pogonskog motora dizalice naftnog bušećeg vretena, gdje je u ulozi pogonskog motora korišten istosmjerni motor sa serijskom uzbudom. Pri projektiranju PI regulatora struje armature kompenzacija protu-djelovan…
A next generation of electronic and optoelectronic devices with high performances and low cost is expected to take off with films of colloidal quantum dots (CQDs) thanks to their unique electrical and optical properties. CQDs are semiconducting nanocrystals synthesized in solution that behave as artificial atoms. Subs…
U teoretskom dijelu rada osvrće se na metodu konačnih elemenata koja se koristi kao baza \naplikacija za simulaciju zavarivanja. Obraćen je kratak uvid u različite aplikacije za simulaciju \nzavarivanja i njihove mogućnosti. Također, u teoretskom dijelu obrađuju se svojstva i podjela \naluminijskih legura, njihova zav…
Sustainable global fibre supply for pulp and papermaking is becoming more important in the advent of climate change and increased demand for paper and paper products worldwide. This has resulted in alternative search for Non-Wood Fibrous(NWF) raw material to supplement existing supply. In this study, the potential of…
El proyecto que se presenta, tiene como fin el analisis de la resistencia al desgaste abrasivo y comportamiento micro estructural, de un acero AISI-SAE 1020, este fue realizado tomando el material en estado de entrega. Ejecutandole procesos de temple a temperatura intercritica de 800°C y revenidos a diferentes tempera…
Dra, Luiziana Ferreira da Silva pelo apoio na realização deste trabalho, Aos meus pais, por tudo, pela oportunidade e incentivo que me deram durante todos esses anos de estudo e principalmente por acreditar em mim e por estar comigo em cada etapa de minha vida, Sou muito grato por ter vocês como pais, Aos meus irmãos…
The main chain dihedral angles play an important role to decide the protein conformation. The native states of a protein can be regard as an ensemble of a lot of similar conformations, in different conformations the main chain dihedral angles vary in a certain range. Each dihedral angle value can be described as a dis…
This release requires an update to the config file in PEcAn web interface. Without this change the web interface will not work. See config.php changes Following are the major new features of this release. Besides these new features many bugs have been fixed, see milestone 1.4.5 list of issues or complete list of commi…
Accurate numerical simulation of soil liquefaction and its effects on geo-structures that contain liquefiable soils remains a major challenge in engineering practice. The main ingredients of a rigorous numerical simulation are: 1) a well calibrated constitutive model that allows for accurate modeling of soil’s stress-…
This paper studies the effects of chemical, elastic and interfacial energies on the equilibrium morphology of misfit particles due to phase separation in binary alloys under chemo-mechanical equilibrium conditions. A continuum framework that governs the chemo-mechanical equilibrium of the system is first developed usi…
The blood-brain barrier (BBB) plays an important role in maintaining the homeostasis of the central nervous system and in protecting the brain from potentially harmful endogenous and exogenous compounds. Nevertheless, it represents also the major obstacle for the diagnosis and therapy of brain diseases. One of the mos…
The structure of the mixed diphosphate ZnCoP2O7 is characterized by the cationic order between the diamagnetic and paramagnetic ions. The Co2+ ions are lodged in octahedral sites whereas the Zn2+ ions occupy distorted square pyramids. The octahedrons CoO6 share a common edge and form dimers Co2O10 separated by dimers…
U ovom završnom radu zadatak je ispitati primjenu numeričkih simulacija koje se koriste kod oblikovanja zavarenih konstrukcija, konkretno ispitati primjenjivost programske aplikacije ˝Visual-Weld˝. \nU početnom, teoretskom dijelu ovog završnog rada ukratko je obrađena aplikacija ˝Visual-Weld˝, odnosno njene mogućnosti…
Ultrasonic velocity and density measurements of 2 1 -hydroxy – 5 1 – bromo – N – (m - hydroxyphenyl) - chalconeimines HBN3HPCU) in DIOXANE – Water mixtures, have been carried out in the concentration range 1×10 -2 -5×10 -2 - mol dm -3 and in different percentage of dioxane – water mixtures. The experimental data have…

Motivation: Traditional and current chemotherapy used to treat cancer disease has always been characterized by the high prevalence of side effects. In order to avoid them, nanotechnology has raised as an acceptable solution to this problem by selectively targeting anticancer drugs to the tumoral cells. Within this pro…
Telah dilakukan pembuatan elektrolit padat untuk Solid Oxide Fuel Cell (SOFC). Elektrolit padat SOFC dibuat dari bahan Calcia Stabilized Zirconia (CSZ) yang didoping dengan Magnesium Oxide. Konsentrasi doping Magnesium Oxide dalam % berat adalah 0%; 0,1%, dan 0,3%. Setelah serbuk CSZ dan MgO dicampur dan digerus hingg…
Motivation: Only a few cells in the human organism keep their ability to regenerate. Hence, modern medical research intends to develop new ways to cultivate these cells with high regenerative capacity with the aim to reconstruct damaged organs and tissues. This is a challenging process currently carried out in 2D cult…
Despite the remarkable properties of ultra-high molecular weight polyethylene, itsapplication is limited by the difficulties encountered in conventional melt processing duethe high degree of entanglement of the chains.The aim of this work is to develop polyethylene based nanocomposites and in-reactorblends, by in situ…
Se analizó el comportamiento microestructural de uniones soldadas de acero AISI 316L empleado en la fabricación de tuberías, las cuales se ven afectadas por agrietamiento en el cordón de soldadura. Se emplearon electrodos revestidos de acero inoxidables de los tipos E 309–16; 310–16 y E 316L–16, según norma de la AWS,…
