Isolated Hypercapneic Respiratory Failure as a presentation of GBS variant: a paraneoplastic association?
No full textGuillain-Barré Syndrome (GBS) is an acute immune-mediated polyradiculoneuropathy, with the Pharyngeal-Cervical-Brachial (PCB) variant being a rare subtype. We report a 60-year-old male presenting with isolated hypercapnic respiratory failure and pulmonary embolism, subsequently diagnosed with PCB-GBS. The patient exhibited cranial and cervical weakness with preserved lower limb strength, cerebrospinal fluid albumino-cytological dissociation, and cervical root enhancement on MRI. Treatment with intravenous immunoglobulin led to rapid recovery. Evaluation for paraneoplastic etiology revealed an oncocytic follicular thyroid neoplasm, managed with thyroidectomy. This case underscores the importance of considering PCB-GBS in unexplained respiratory failure and highlights the rare paraneoplastic association with thyroid malignancy
Design of a working model of an upper limb prosthesis: wrist mechanism
No full textThis thesis demonstrates a new design for an upper limb prosthetic wrist that gives 3 independent degrees of freedom (DOFs) through individual mechanisms. A human wrist has 3 degrees of freedom i.e. Flexion-Extension, Radial- Ulnar deviation and Pronation-Supination. The upper limb prostheses that are currently available in the market generally provide 1 (usually Pronation- Supination) or at most 2 degrees of freedom, which is not su cient for daily life. For this thesis, a new wrist having all the 3 DOFs was designed in the SolidWorks software, a prototype was 3D printed and a basic analysis of the mechanical properties of the model through SolidWorks simulation was carried out. The prototype mechanisms were then connected to servo motors, with potentiometers as their inputs, that were programmed through an arduino and were tested to see if they work as expected. Faithful recreation of the wrist motions was achieved and the range of motion (ROM) of this prosthesis was similar to the ROM of an actual human wrist. This thesis also looks at the other prostheses that are available in the market or are under development and their limitations are discussed. The goal of this thesis is to present a design of an upper limb prosthesis which addresses some of the limitations while also encouraging further research and development in this eld and will hopefully result in more people with amputations choosing to use prosthetics in their daily lives.M.S.Includes bibliographical referencesby Sahil Vikas Dang
Measurement of the residence time distribution of FCC catalyst in rotary kilns
No full textContinuous rotary kilns are among the most widely used solid handling equipment for industrial applications such as drying, incineration, mixing, pre-heating, humidification, calcining, and gas-solid reactions. Longer residence times prove beneficial in ensuring that all particles have been treated sufficiently, but this can lead to large material and energy costs. As a result, efficient calcination will require shorter residence time and lower axial dispersion. The purpose of this research is to contribute towards a better understanding of these mass transfer mechanisms in rotary kilns, using industrially relevant equipment and operating conditions directed towards large-scale catalyst manufacturing. In this work, the residence time distribution and axial dispersion coefficient for a free flowing fluid cracking catalyst (FCC) powder is measured in pilot-scale kilns using a tracer study developed by Danckwerts (1952). The tracer study was used to determine residence time distributions for different sets of operating parameters, which were successfully matched to the Taylor fit of the axial dispersion model and the Sullivan prediction for mean residence time. It was found that the mean residence time and axial dispersion coefficient varied inversely with rotary speed of the kiln. The bed depths corresponding to respective flow regimes in such a calcination system were not previously reported. The predictive models showed accuracy for the system considered, even at fill levels <1% which was not the case in previously reported studies with cohesive powders.M.S.Includes bibliographical referencesby Sahil Suleman Navodi

Systematic Study of Green water and its Impact on Structures
No full textThe Offshore Industry is one of the most challenging industries. Offshore vessels must survive all weather conditions over its lifetime. In heavy storms, waves and ship motions become so large that water flows onto the deck, It is referred to as Green Water and is a serious challenge that needs to be considered in designing offshore vessels. The methods for making green water prediction are limited. More data needs to be collected to ensure safe navigation and operation.ComFLOW is a numerical tool in the field of Offshore Engineering used to study these non- linear and complex green water phenomena. ComFLOW is a Navier-Stokes solver with Volume of Fluid(VOF) for free surface motion, It has been used for simulation of dam break flows as a model for green water flow on deck and falling objects in calm waters. In this research, it is used to generate dam-break waves along with simulations involving regular and irregular waves leading to water on deck. It is used to evaluate whether dam break model is a complete model for studying green water loading on deck. A grid convergence study for ComFLOW is conducted along with a verification of ComFLOW for 2 dimensions. Optimum grid cell size is advised for accurate and stable results in ComFLOW for 2 dimensions. Dam break simulations are performed on an idealized deck to observe changes from that of a regular domain boundary.Wave prediction and it’s impact on the topside facilities due to regular and irregular waves is the objective of this research. Absorbing boundary conditions are used to prevent wave reflections. Non-breaking waves are generated for irregular waves. Impact of water on the structure on deck is of primary importance. The wave height is an important parameter in dealing with such green water events. The role of wave height along with the distance of structure on deck is studied in this research. The input parameters such as dam height and distance of the structure from dam height are varied. Localized impact pressures are considered and changes in impact pressure are observed. A structure in regular and irregular waves is also compared with a dam break model. The main conclusions are:• Variations in dam break loads compare well to theory.• The dam break is not a complete model for assessing green water loads.Offshore and Dredging EngineeringMarine Technology | Ship Hydromechanic
