The developments in construction make it compulsory for architects to plan the high rise structures in RCC. Unfortunately due to some reasons like gas explosion, terrorist attack, fire etc. high rise structures undergoes some major component failure. As the major component fails, sometimes part of the structure or who…
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
Collagen fibrils, with dry diameters of the order of 100 nm, are the fundamental building blocks in connective mammalian tissues. While the mechanical behavior of tissues has been studied extensively and was shown to follow non-linear viscoelasticity, as similar quantitative understanding of the time-dependent deforma…
Several full-dimensional potential energy surfaces (PESs) are reported for vibrating CO adsorbates at two coverages on a rigid NaCl(100) surface based on first principles calculations. These PESs reveal a rather flat energy landscape for physisorption of vibrationless CO on NaCl(100), evidenced by various C-down adsor…
Cette these a pour enjeu le developpement de biomateriaux modulables pour l’ingenierie tissulaire. Trois types de biocomposites sont presentes, sous forme de filaments ou de membranes autoportees presentant des fibres alignees ou non. Le collagene, principal constituant des tissus conjonctifs, en est la matrice hote.…
Tandem solar cells (SCs) based on perovskite and silicon represent an exciting possibility for a breakthrough in photovoltaics, enhancing SC power conversion efficiency (PCE) beyond the single-junction limit while keeping the production cost low. A critical aspect to push the tandem PCE close to its theoretical limit…
Naegleria gruberi is a free-living non-pathogenic amoeba. It is a close relative to Naegleria fowleri, a pathogen that causes primary amoebic meningoencephalitis in humans (PAM). As a free-living organism, Naegleria gruberi is adapted to aerobic lifestyle but also possesses remarkable traits of anaerobic organism such…
In today's modern age, copper is used in cables and all electrical and electronic devices. Today, there is almost no electrical device that does not contain copper. Copper is increasingly being recycled from waste cables and almost half of the copper in new cables or electronic devices is obtained as a secondary raw m…
Práce se zabývá problematikou 3D tisku metodou Selective Laser Melting za vyšších teplot s využitím předehřevu. Cílem práce je návrh nanášecího zařízení pro tenkostěnné díly pro tiskárnu 280HL od společnosti SLM Solutions. Byly rozebrány současné metody předehřevu a na základě jejich zhodnocení bylo navrženo nové naná…
W wielu międzymetalicznych związkach ceru występują tak interesujące stany, jak faza ciężkich fermionów, mieszana walencyjność, izolator Kondo i nielandauowska ciecz Fermiego. Materiały ciężkofermionowe, które są przedmiotem badań w znacznej części pracy, posiadają nośniki ładunku elektrycznego o masach wielokrotnie w…
Abstract Background: Epidermolysis bullosa is a rare genetic skin disorder with four main types. One of the most debilitating subtypes is recessive dystrophic epidermolysis bullosa (RDEB). Patients experience frequent blister formation that occurs spontaneously or as a result of minor pressure or friction. This often…

Esta bem estabelecido que o ferro (Fe) e um material promissor para uso em aplicacoes biomedicas. No entanto, ele exibe uma taxa de corrosao muito lenta quando presente em meios fisiologicos, o que pode torna-lo incompativel para aplicacao como implantes degradaveis. Neste trabalho, o ferro puro processado por HPT (Hi…
Abstract Two-dimensional (2D) materials1–5 offer a unique platform from which to explore the physics of topology and many-body phenomena. New properties can be generated by filling the van der Waals gap of 2D materials with intercalants6, 7; however, post-growth intercalation has usually been limited to alkali metals8…
Abstract This work concerns the discovery of a time-domain "anomaly" in the Infra-Red synchrotron radiation spectra emitted by electrons and positrons from both the DA NE -Factory (Frascati National Laboratories, Italy) and HFL (Hefei Light Source at NSRL(National Synchrotron Radiation Laboratory, People’s Republic of…
In the last decades, cancer treatment modalities have been moved towards high technological developments that indicate in the external beam radiotherapy the primacy of delivering a highly conformal radiation dose to the target volume. In this scenario, proton therapy at Paul Scherrer Institute (PSI) occupies a relevan…
Purpose. The aim of the research is to improve the maintenance system of a traction motor (TM) ED-118A by predicting the life of a frame insulation and determining recovery moments while ensuring the lowest unit costs for performing a major repairs of a volume 1 (MjR-1) and permanent repair of a volume 3 (PR-3), takin…
In 80 years of nuclear reactor history two types of reactors were constructed, one leading to energy production and the other one for scientific research. At the moment, the operational nuclear reactors are represented by 440 nuclear power plants and 220 research reactors, therefore it can be easily deducted the high…
Recently, many unexpected fine structures in electric, magnetic, and thermoelectric responses at extremely magnetic fields in topological materials have attracted tremendous interest. We propose a new mechanism of quantum oscillation beyond the strong-field quantum limit for Dirac fermions. The amplitude of the oscill…
L’objectif de ce travail de thèse consiste à identifier une ou plusieurs matrices époxydes répondant aux exigences industrielles issues de l’application des câbles électriques et compatibles avec le procédé de pultrusion. Les conditions de fonctionnement de ces câbles sont des températures de l’ordre de 150°C avec des…
