Abstract:

Dissertação para obtenção do Grau de Mestre em Engenharia Química e Bioquímica<br>The main goal of this work is to optimize the performance of the PDLC films with the introduction of an additive, in this case the triton X100. The polymer matrix of the PDLC is based on monomers, such as Tri(ethylene glycol) dimethacrylate and poly(ethylene glycol) dimethacrylate with molecular weight of 875 which were thermal polymerized using α,α-azobisisobutyronitrile as initiator. Different aspects were investigated, such as the study of the dynamics of the transition ON/OFF state using a high-frequency a

Abstract:

Dental anthropology was wide ranging implications for the field of anthropology. Teeth have become important sources of data about the individual as well as possibly being able to identify them. One problem that can arise is the chemical destruction of teeth whether it be diagenesis in an archaeological context or deliberately in a forensic context. In terms of deliberate destruction of the body several household chemicals are cheap and easily assessable. The purpose of this research is to look at how six household chemicals affect both deciduous and permanent tooth classes. The six chemicals

Abstract:

Magnetization processes in a sintered Nd-Fe-B permanent magnet (NEOMAX-35) were examined on a small scale using a Hall-effect microprobe with an active area 75 μm on a side. Probes were made by evaporating bismuth through a stencil mask onto glass slides. Experiments were performed by placing a probe onto the polished pole face of a Nd-Fe-B magnet and inserting the probe-magnet assembly into an electromagnet. Barkhausen steps, indicating rapid domain wall motion, were observed (superimposed upon the blank probe signal) in the demagnetization of a fully magnetized magnet. Magnetization traces f

Abstract:

Polyethylene terephthalate multifilament fabrics used as filtration and operating room textiles possess through-thickness pore channels at the yarn intersections (mesopores). These pore channels pose a risk for the penetration of contaminated fluids and particles. The size of pore channels may be reduced by high-density weaving. However, this leads to reduced drapability and thus to degraded application properties of the fabric. To satisfy the requirements without impeding the physiological properties of the textile, fluid- and particle-tight fabrics are developed. This was realized by partial

Abstract:

Wind energy has been the fastest emerging renewable energy source over the last decade. The overriding provisos to minimise greenhouse emissions and increasing concerns regarding energy security have been the major inducements for many countries to make a resolute transition to new and non-conventional power sources. Direct-drive systems for wind turbines are potentially a more reliable alternative to gearbox driven systems. Gearboxes are liable to significant accumulated fatigue torque loading with relatively high maintenance costs. It is with this in mind that the primary focus of this resea

This thesis documents the work and research effort on the design, fabrication and testing of a magnetocaloric MEMS microcooler, focusing on the testing of the microcooler at low magnetic fields. The phenomenon of magnetocaloric effect (MCE), or adiabatic temperature change, which is obtained by heating or cooling magnetic materials due to a varying magnetic field, can be exploited in the area of magnetic refrigeration as a reliable, energy-efficient cooling system. In particular, its applications are being explored primarily in cryogenic technologies as a viable process for the liquefaction of

Abstract:

This thesis focuses on the development of a novel Direct Torque Control (DTC) scheme for permanent magnet (PM) synchronous motors (surface and interior types) in the constant torque region with the help of cost-effective hall-effect sensors. This method requires no DC-link sensing, which is a mandatory matter in the conventional DTC drives, therefore it reduces the cost of a conventional DTC of a permanent magnet (PM) synchronous motor and also removes common problems including; resistance change effect, low speed and integration drift. Conventional DTC drives require at least one DC-link volt

Abstract:

Twist plays an important role to impart tensile strength in yarn during the spinning process. In the most widely used ring-spinning machine for short staple yarn production, a combination of ring and traveler is used for inserting twist and winding the yarn on cops. The main limitation of this twisting mechanism is the friction between the ring and traveler, which generates heat at higher speed and limits the productivity. This limitation can be overcome by the implementation of a magnetic bearing system based on superconducting technology, which replaces completely the existing ring/traveler

By ignoring that effect, the Dose Volume Histogram (DVH) is right-shifted and dose analysis parameters such as the D90 are overestimated. The tissue-composition effect is due to the pres

Abstract:

En este estudio se midió la microdureza Vickers del esmalte dental después de la exposición a tres bebidas industrializadas más consumidas en la ciudad de Lima y una bebida control, para evaluar el efecto erosivo de esta bebidas ácidas y su relación con la acidez titulable, el nivel de pH y el efecto buffer de las mismas. Se elaboraron 60 bloques de esmalte superficial de 2mm de espesor por 2-4mm de longitud; se colocaron en acrílico de curado rápido en moldes circunferenciales de 10mm de diámetro y 5mm de altura en diferentes colores (azul para la bebida carbonatada, anaranjado para la bebid

Abstract:

Les prairies permanentes peuvent fournir une grande diversité de services écosystémiques. Elles se trouvent dans des conditions contrastées en termes de gestion et de climat en Europe. Cette diversité de conditions induit une grande variété de types de prairies différant par leur végétation et leur fourniture en services écosystémiques. Certains travaux suggèrent que le fonctionnement des écosystèmes prairiaux peut être directement relié à des critères de diversité fonctionnelle végétale. Ces critères, qui pourraient être utilisés pour évaluer les services écosystémiques, sont influencés par l

Abstract:

In this thesis, field oriented control of permanent magnet synchronous motors using three-level neutral-point-clamped inverter is studied. Permanent magnet synchronous motors are used in high performance drive applications. In this study, the permanent magnet synchronous motor is fed by three-level neutral-point-clamped inverter. For three-level neutral-point-clamped inverter different space vector modulation algorithms, which are reported in literature, are analyzed and compared via computer simulations. The voltage balance on dc-link capacitors is also analyzed and a software control method

Abstract:

Perceived job insecurity is receiving increasing recognition as an important determinant of employee work outcomes. Empirical research consistently shows that job insecurity perceptions are associated with adverse reactions by employees, in terms of reduced psychological well-being (De Witte, 1999), job satisfaction (O'Quin & LoTempio, 1998), and organisational commitment (Rosenblatt & Ruvio, 1996). Turnover intentions for the job-insecure are higher (Tivendell & Bourbonnai, 2000) as well. It is therefore important to understand what may increase or decrease such detrimental effects of job
