Aerodynamic Evaluation of a Rally Car using numerical methods
No full textThe dissertation covers the introduction of development and importance of aerodynamics in a Rally car used for the World Rallying Championships. Due to the lack of sources available worldwide, a brief literature review has been highlighted in the thesis. The main aim is to study and analyse the impact of aerodynamics on the performance, handling & stability of the Subaru Impreza STi 2014 WRC Sedan, equipped with & without aerodynamic flow-control devices in yawed and head-on flows which will add-up some additional information as a source for further research and development purposes.
Before proceeding into the rally car simulations, a comparison, simulation & validation of CFD results against published sources results of a Saloon Car & NACA 2415 Aerofoil are been demonstrated. The thesis also covers various meshing methods used and their impact on the results obtained. This thesis will cover information and importance of various aerodynamic-flow-control-devices.
The focus is based upon head-on & yawed flows and the importance of aerodynamic-control-devices. This will help to study the effects of each device on overall performance for different simulations. The results shall be evaluated under yawed and head-on flows and compare with any similar Journals, books, articles, or sources if possible.
Then after, the simulations are evaluated on the study of ‘impact of change in ride-heights with the stability and handling’ of a rally car, and their effects are been studied and discussed, respectively and the results showed a similar behaviour as mentioned in the literature review.
Finally, some rear-wing designs and configurations are been proposed and iterated based upon the concepts, ideas, and allowance of the rules and the results been compared for its drag, lift pressure coefficients, vorticity & balance characteristics
Bollywood cinema: A critical genealogy
Get PDF"Bollywood" has finally made it to the Oxford English Dictionary. The 2005 edition defines it as: "a name for the Indian popular film industry, based in Bombay. Origin 1970s. Blend of Bombay and Hollywood." The incorporation of the word in the OED acknowledges the strength of a film industry which, with the coming of sound in 1931, has produced some 9,000 films. (This must not be confused with the output of Indian cinema generally, which would be four times more). What is less evident from the OED definition is the way in which the word has acquired its current meaning and has displaced its earlier descriptors (Bombay Cinema, Indian Popular Cinema, Hindi Cinema), functioning, perhaps even horrifyingly, as an "empty signifier" (Prasad) that may be variously used for a reading of popular Indian cinema. The triumph of the term (over the others) is nothing less than spectacular and indicates, furthermore, the growing global sweep of this cinema not just as cinema qua cinema but as cinema qua social effects and national cultural coding. Although Indian film producers in particular, and pockets of Indian spectators generally, continue to feel uneasy with it (the vernacular press came around to using "Bollywood" only reluctantly), its ascendancy has been such that Bombay Dreams (the Andrew Lloyd Weber musical) and the homegrown Merchants of Bollywood both become signifiers of a cultural logic which transcends cinema and is a global marker of Indian modernity. As the Melbourne (March 2006) closing ceremony of the Commonwealth Games showed, Bollywood will be the cultural practice through which Indian national culture will be projected when the games are held in Delhi in 2010. International games (the Olympics, World Cup Soccer, Asian Games, Commonwealth Games, and so on) are often expressions of a nation's own emerging modernity. For India that modernity, in the realm of culture, is increasingly being interpellated by Bollywood
Yash Chopra
No full textAs a charismatic director in the Indian film industry, Chopra’s name is synonymous with the glamour of the romantic film and a certain style within Indian culture. Spanning four decades, his directed features include some of the classic films of Indian film history, such as Deewaar and Kabhi Kabhie. His directorial career began in 1959 with Dhool Ka Phool and he has been a major producer since 1973, consolidating his success in the 1990s with a series of huge box office hits including Dilwale Dulhaniya Le Jayenge. He has also worked in other Hindi movie genres, directing action movies such as Mashaal and a thriller, Darr. This book discusses in depth his work with the Hindi megastar Amitabh Bachanan in films such as Deewaar, Trishul, Kala Patthar and Silsila and how, in his transformation of the look of mainstream cinema in Dil To Pagal Hai and other films, Yash Chopra has proved to be a tireless innovator within a mainstream tradition. The author integrates this analysis with information about the man and his work, based on interviews with Yash Chopra, his family, his colleagues, his stars, his contemporaries and major critics that include views from Amitabh Bachchan, Shahrukh Khan, Shashi Kapoor and Sri Devi. A study of a top contemporary Indian film director, Rachel Dwyer’s book also examines the influence on Chopra of predecessors such as Raj Kapoor and how his own legacy can be seen in such films as Kuch Kuch Hota Hai and younger directors such as Karan Johar and Aditya Chopra

Screening and Surveillance of Colorectal Cancer: A Review of the Literature
No full text: Colorectal cancer (CRC) has the highest mortality rate among men and is the second highest among women under fifty, with incidence and mortality rates rising in younger populations. Studies indicate that up to one-third of patients diagnosed before fifty have a family history or genetic factors, highlighting the need for earlier screening. Contrariwise, diagnosis in healthy subjects through screening strategies enables early-stage detection of the tumor and better clinical outcomes. In recent years, mortality rates of CRC in Western countries have been on a steady decline, which is largely attributed to widespread screening programs and advancements in treatment modalities. Indeed, early detection through screening significantly improves prognosis, with stark differences in survival rates between localized and metastatic disease. This article aims to provide a comprehensive review of the existing literature, delving into the performance and efficacy of various CRC screening strategies. It navigates through available screening tools, evaluating their efficacy and cost-effectiveness. The discussion extends to delineating target populations for screening, emphasizing the importance of tailored approaches for individuals at heightened risk

However, the limited understanding of the transport mechanisms involved in MF can hinder process optimization efforts. Porous media modeling can help address this gap. In this research, the MF of foods was modeled by solving hybrid mixture theory-based two-scale unsaturated transport equations and Maxwell's equations of electromagnetism. The food matrix was modeled as a deformable and viscoelastic material. Modeling the MF of foods is challenging due to the multiple phases (gas, water, oil, and solids) and physics (heat transfer, mass transfer, deformation, and electromagnetics) involved in the process. A stepwise approach was employed wherein the model complexity was increased in each step. First, a previous CF model developed in our research group was modified and solved to account for viscoelastic deformations. Then, the microwave drying of foods was modeled as it is simpler than MF due to the absence of the oil phase. Finally, MF was modeled. Frying and microwave drying experiments were conducted to collect the model validation data. While earlier frying models in the literature ignored the volume changes of foods during frying, the CF model developed in this research accounted for the deformation of the food matrix by utilizing the pore pressure (p_pore) as the driving force governing deformation. The negative gauge p_pore near the sample surface during frying was expected to have caused the contraction of the surface layers, and the potato sample shrank by 18.5% for a frying time of 300 s. The p_pore is also expected to impact the oil penetration in foods during frying. The oil content of the sample increased significantly in the first minute of frying when the p_pore in the food was low. The oil content profile plateaued in the intermediate frying stages. This was expected due to an increase in the magnitude of p_pore in the sample. The p_pore attained a peak value of 19.2 kPa (gauge) at the sample center. The subsequent decrease in p_pore was expected to have enabled the oil uptake by the sample in the later frying stages. During microwave drying, the electric field was centrally concentrated in the cylindrical potato sample. However, the heat concentration behavior was size-dependent. The high magnitudes of pressure in the sample core (peak gauge p_pore at the center: 103.8 kPa) during microwave drying caused outward moisture movement and an expansion of the core. The magnitude of microwave power dissipation decreased in the drier parts of the sample, which may help avoid internal burning and aid the 'moisture-leveling' effect of microwave drying. Sensitivity analysis revealed a significant impact of changes in microwave frequency on the drying of foods. Experiments showed that MF at 2.45 GHz frequency led to the highest heating rates and pressure magnitudes (peak values at the sample center: 107.3°C and 24.9 kPa), followed by MF at 5.8 GHz frequency (peak values: 104.1°C and 20.8 kPa) and CF (peak values: 100.5°C and 13.8 kPa). Below a moisture content value of 3 g/g solids, the oil content of French fries increased rapidly with a decrease in moisture content for CF and relatively slowly for MF. The stress relaxation data of French fries indicated that MF at 5.8 GHz can produce crunchier fries, potentially due to intense crust heating at this frequency. Simulations with the MF model showed that MF produced samples with lower oil content than CF at a given endpoint moisture content (3-33% reduction in oil content). MF also reduced frying times by 33-76%. The spatiotemporal distribution profiles for variables like electric field, microwave power dissipation, temperature, pressure, and moisture content were analyzed. The power dissipation followed the drying front in the French fries during MF. This can cause the thickening of the crust and make the French fries crunchier. MF at 2.45 GHz led to samples with lower oil content than MF at 5.8 GHz, likely due to the deeper penetration of microwaves and higher magnitudes of p_pore in the sample during the former. Processing implications were discussed, and suggestions were made for future improvements to the design of the microwave fryer prototype used in this research. The results from this work improved the understanding of the transport mechanisms involved in MF
Segmentation of Front Viewed Single Phase Diamond
No full textThe estimation of Quality of diamond plays a very important role in finding its price and add a market value. Quality of diamond is being estimated in the market today by just looking into the diamond thought naked or with a lens, but the quality estimated in this way is less accurate and varies from person to person in which the consumers are put into confusion whether the diamond is of good quality or not. It is sometimes difficult to identify whether the diamond is real or not. If we use a computer aided system then the estimation of quality of diamond can be estimated accurately and quickly. Thus, paper aims to develop such computer aided system which will estimate the quality of diamond based on Gemological Institute of America GIA standards. Yash Jain N | T. P.

Laing distal myopathy with a novel mutation in exon 34 of the MYH7 gene
No full textWe investigated a four-generation family of German ancestry with distal myopathy. Four individuals in two generations were affected. Foot and toe extensor paresis progressing very slowly over decades was the core neurological sign, reflected by fatty infiltration of the lower leg extensor muscles on muscle MRI. Additionally, finger extensor paresis was present in two patients and quadriceps muscle paresis in one. Distal sensory signs had initially given rise to the diagnosis of axonal Charcot Marie Tooth (CMT) disease. Two patients had extended verrucae of their foot sole, which may or may not be part of the disease spectrum. All four patients had a novel c.4645G > C mutation in exon 34 of the MYH7 gene that was not present in three clinically unaffected family members. Muscle biopsy of one patient revealed a myopathic pattern associated with type 1 muscle fibre atrophy and core-like lesions in many muscle fibres consistent with a myosin-related myopathy. We conclude that some of the typical clinical signs such as extensor weakness of the big toe and the little finger may only develop in the further course of the disease. (C) 2016 Elsevier B.V.
