Spontaneous infection of ascites fluid: impact of etiology - Dorra Trad

Computational Fluid Dynamics Study - Ana Paula Silva Artur

The gyratory bed is a highly viable piece of equipment due to its efficient fluid-particle contact and high heat and mass transfer rates in industrial operations. An efficient way of studying the operating behaviour of the equipment at lower costs is to use computational tools whose function is to verify and analyse the best performance of this equipment in the face of a requested operation. One of these tools is Computational Fluid Dynamics (CFD), as it is able to simulate the characteristics of..

Numerical Study of Mixed Convection in a Cavity - Lyes Bordja

Convection is a way of transporting energy by means of potential gradients and fluid movement. Convection is the most important mechanism for transferring energy between a solid surface and a liquid or gas at a different temperature. Energy transfer by convection from a surface whose temperature is higher than that of the surrounding fluid takes place in several stages. The essential characteristics of heat transfer by convection are the transport of energy by molecular movement, known as 'diffusion',..

Fluid mechanics of wing and fin - Vasilij Nikolaevich Hramushin

Some aspects of consistent design and interrelated engineering solutions in hydromechanics of complex unsteady flows optimizing controlled motions of flexible blades and rigid wings of fin thrusters and hydrodynamic stabilizers are considered, including issues of general layout of special mechanisms for recreating hydromechanics processes with useful force reactions, and especially for induced and external manifestations of gradient and eddy currents, with solution of the problem of flow disruption..

Imaginary formation and subjectivity in social networks - Isabel Frantz

In this work, we seek to understand, from the theoretical-methodological perspective of Discourse Analysis, the imaginary formation and the subjectivities produced by it in the discursiveness of the Portuguese Language community on Fac. In the material we analysed, we identified three predominantly functioning imaginaries: the \Imaginary of linguistic correctness\ affiliated with the memory of colonisation, signifying the fluid Brazilian language as wrong, flawed, while the imaginary language of..

COVID-19 coronavirus disease - Houria Messid Bouziane Meflah

The way in which Covid-19 manifests itself is highly heterogeneous. The manifestations most frequently cited by patients of all ages are the classic signs of respiratory infection: fever and cough. A build-up of fluid in the bronchioles may also occur as a result of the infection, leading to breathing difficulties. This book will present the clinical, biological and radiological features of Covid 19, based on a literature search.

Pocket ultrasound for ascites and paracentesis assessment - Daniel Keil Ríos

The presence of ascites may be suggestive of multiple pathologies. Physical examination cannot always detect it, particularly when the amount of fluid is low or if it coexists with obesity. Its early detection has important diagnostic, therapeutic and prognostic implications. This is why ultrasound has become essential for its detection. Moreover, its usefulness in performing guided procedures has been demonstrated on multiple occasions and it has become a tool of daily use in hospital services...

Prevention of infection in peritoneal dialysis - Meriam Khadhar

Peritoneal dialysis is one of the methods of extrarenal purification in patients with end-stage renal disease and receiving replacement therapy.In 2015, estimates suggest that 272,000 people are on peritoneal dialysis worldwide about 11% of the dialysis population. Infectious complications are the most feared complications of this technique. There are two main types of infections: infections of the catheter outlet and infections of the dialysis fluid. These peritonitises occur essentially as a result..

Organophilic Clay for Ultra-Deepwater Drilling Fluids - Francisco Kegenaldo Alves de Sousa

Unlike the rest of the world, Brazil's largest oil fields are located offshore, which makes their exploitation an ever greater challenge as reservoirs are discovered under deeper water every day. Organophilic clays are an essential input in the production of organic-based drilling fluids. In this study, three types of clay were organophilized and their compositions were introduced into paraffin, ester and diesel oil-based fluid formulations, with the aim of evaluating the performance of these fluids..

Application of the Minimum Amount of Lubrication in Abrasion Machining - Josà Claudio Lopes

The minimum quantity lubrication (MQL) technique has emerged as an alternative to the use of conventional coolant lubrication, as the application of atomized lubricant at high pressure reduces the amount of cutting fluid required for machining. Several studies have aimed to improve the technique when using it in abrasive machining, as it has been noted that MQL is deficient in removing chips, causing the phenomenon of caking, which impairs the efficiency of the process, so mechanisms that can clean..

Influence of the amount of fluid on the turning of ABNT1045 steel - Ítalo de Abreu Gonçalves

The metalworking industry is characterised by the high quality of its components, and machining is responsible for a considerable portion of the search for improvements in its products. In the manufacture of parts for the sector, the use of ABNT 1045 steel stands out for its good mechanical properties and low cost. The efficiency of the use of coolants in turning machining processes is widely questioned in the literature. Therefore, this work studied alternatives for turning ABNT 1045 steel. For..

Psychology and its crossings - Janete Leony Vitorino

We can define \crossing\ as the act or effect of crossing, of passing through; transpassing. This collection of articles goes through a trajectory of research and work in the field of Clinical Psychology as possibilities of citing moments and stories of clinical evolution and/or clinical cases that sought within the subjective look of the evaluator and subject of construction and under construction, a passing on of fluid contents to other people who need or seek possibilities in clinical research...

Use of locked nails in femur fractures in hospitals - Fernando Gómez

Knee and shoulder pain can have various causes. Here are a few possible ones. Knee pain: 1. Sports injuries: such as sprains, ligament or cartilage tears, fractures, among others. 2. Joint wear and tear: osteoarthritis is one of the main causes of chronic pain in the knee, especially in older people. Bursitis: inflammation of the bursae (small fluid-filled sacs) that cushion the knee joint. Tendonitis: inflammation of the tendons in the knee, usually caused by repetitive activities or injury.Shoulder..

The world today is changing and diverse, but more homogeneous than it seems. This diversity and homogeneity are paradoxes of our international society, with which we must live and in which we must necessarily be. And under these premises, information plays an important role, together with the immediacy of communications and the possibility of connecting with any part of the world. This obliges us to make the effort to be aware of it and to be fluid in our movement through this society.

Iran's geostrategy in the Middle East - Lea Raso Della Volta

Since 1979, Iran has been waging a shadow war in the Middle East, heir to the doctrine of mosaic warfare that emerged during the Cold War. From now on, modern warfare will be waged by small units, assembled to fight in a fluid and decentralized manner, without a previously defined structure.To carry out this shadow war and achieve its goals: leadership in the Middle East, Iran relies on the proxies, or Shiite network responsible for maintaining the enemies of the Islamic Rlic, under fire and practice..

Water and Electrolytes - Jean Le¿Clerc Nicolas

The hydro-electrolyte and acid-base balance is of vital importance to maintain correct homeostasis, as it regulates most of the organic functions. It is a complex subject in its therapeutic management due to the varied and not easy formulas designed for the correction of these alterations. The aim of this work is to review the subject in an updated way, showing a novel method that can facilitate the correction of dehydration, but for the first time taking into account the basic daily fluid needs,..

New trends in Hispanic crime narratives - Rodrigo Pereyra

It is unquestionable that enthusiastic readers of the noir genre seek out and follow these works for the themes of literary tension, for the fast and fluid handling of each plot, for the atmosphere of tension between political power and corruption, for the violence and injustice presented within an aesthetic of crime; but it is also true that these stories are sought out and read because they present the reality of the link that exists between norm and violence in 21st century society. Understood..

Understanding Foucault - João Felipe Zini Cavalcante de Oliveira

This work aims to make it easier to understand Foucault's studies on human sexuality. The French philosopher has a reputation for writing eloquently, which doesn't always mean that reading is easy or fluid. In this sense, we have endeavoured to present the broad outlines of his thought for those who wish to begin studying Foucault. This volume seeks to clarify the main ideas of the work History of Sexuality: The Use of Pleasures, in which Michel Foucault looks at the \evolution\ (and we'll see..
