Red Blood Cell Aggregation

Red Blood Cell Aggregation

Red blood cells in humans—and most other mammals—have a tendency to form aggregates with a characteristic face-to-face morphology similar to a stack of coins. Known as rouleaux these aggregates are a normally occurring phenomenon and have a major impact on blood rheology. What is the underlying mechanism that produces this pattern? Does this really happen in blood circulation? And do these rouleaux formations have a useful function? The first book to offer a comprehensive review of the subject Red Blood Cell Aggregation tackles these and other questions related to red blood cell (RBC) aggregates. The book covers basic clinical and physiological aspects of this important biophysical phenomenon and integrates these areas with concepts in bioengineering. It brings together state-of-the-art research on the determinants mechanisms and measurement and effects of RBC aggregation as well as on variations and comparative aspects. After an introductory overview the book outlines factors and conditions that affect RBC aggregation. It presents the two hypotheses—the bridging model and the depletion model—that provide potential mechanisms for the adhesive forces that lead to the regular packing of the cells in rouleaux formations. The book also reviews the methods used to quantify RBC aggregation in vitro focusing on their importance in clinical practice. Chapters discuss the effect of RBC aggregation on the in vitro rheology of blood as well as on tube flow. The book also looks at what happens in the circulation when red blood cells aggregate and examines variations due to physiological and pathophysiological challenges. The concluding chapter explores the formation of red blood cell aggregates in other mammals. Written by leading researchers in the field this is an invaluable resource for basic science medical and clinical researchers; graduate stu

Numerical Modeling of COVID-19 Neurological Effects ODE/PDE Analysis in R

Numerical Modeling of COVID-19 Neurological Effects ODE/PDE Analysis in R

Covid-19 is primarily a respiratory disease which results in impaired oxygenation of blood. The O2-deficient blood then moves through the body and for the study in this book the focus is on the blood flowing to the brain. The dynamics of blood flow along the brain capillaries and tissue is modeled as systems of ordinary and partial differential equations (ODE/PDEs). The ODE/PDE methodology is presented through a series of examples 1. A basic one PDE model for O2 concentration in the brain capillary blood. 2. A two PDE model for O2 concentration in the brain capillary blood and in the brain tissue with O2 transport across the blood brain barrier (BBB). 3. The two model extended to three PDEs to include the brain functional neuron cell density. Cognitive impairment could result from reduced neuron cell density in time and space (in the brain) that follows from lowered O2 concentration (hypoxia). The computer-based implementation of the example models is presented through routines coded (programmed) in R a quality open-source scientific computing system that is readily available from the Internet. Formal mathematics is minimized e. g. no theorems and proofs. Rather the presentation is through detailed examples that the reader/researcher/analyst can execute on modest computers. The PDE analysis is based on the method of lines (MOL) an established general algorithm for PDEs implemented with finite differences. The routines are available from a download link so that the example models can be executed without having to first study numerical methods and computer coding. The routines can then be applied to variations and extensions of the blood/brain hypoxia models such as changes in the ODE/PDE parameters (constants) and form of the model equations. | Numerical Modeling of COVID-19 Neurological Effects ODE/PDE Analysis in R

Nanotherapeutics From Laboratory to Clinic

Nanotherapeutics From Laboratory to Clinic

The emergence of nanotherapeutics is attributable to the integration of nanotechnology recombinant DNA technology and synthetic organic chemistry with medicine for treating critical human diseases in a more efficient and specific molecular approach than therapy with conventionally-designed and formulated drugs. Nanotherapeutics: From Laboratory to Clinic comprehensively discusses the current shortcomings for delivery of classical (small) drugs macromolecular therapeutics and recombinant vaccine via the common intravascular and extravascular routes. The book describes the synthetic/chemical engineering methods as well as recombinant hybridoma and phage display technologies to fabricate different types of nanoparticulate carriers and drugs. It also reveals the diversified approaches undertaken by harnessing nanotechnology to overcome the multistep extracellular and intracellular barriers and to facilitate the development of novel strategies for therapeutic delivery and imaging. The author elaborates on the preclinical and clinical trials of potential nanoparticle-based products in animal models and patients and the approval/commercialization of nanotherapeutics addressing all relevant human diseases. A focus on the above issues in a concise but illustrative manner fills the gap between the laboratory findings originating from the research on identification of cellular and systemic barriers of classical and macromolecular drugs along with development of strategies for fabrication and testing of nanotherapeutics and the clinical outcomes emanating from the testing of the selected potential nanotherapeutics on patients of particular diseases. The book also fills a gap in the existing literature between the design and development of diversified nanotherapeutics for various purposes and the investigation and evaluation of potential barriers and resultant therapeutic efficacy of those nano-medicine formulations. | Nanotherapeutics From Laboratory to Clinic

Structural Design from First Principles

Structural Design from First Principles

This enlightening textbook for undergraduates on civil engineering degree courses explains structural design from its mechanical principles showing the speed and simplicity of effective design from first principles. This text presents good approximate solutions to complex design problems such as Wembley-Arch type structures the design of thin-walled structures and long-span box girder bridges. Other more code-based textbooks concentrate on relatively simple member design and avoid some of the most interesting design problems because code compliant solutions are complex. Yet these problems can be addressed by relatively manageable techniques. The methods outlined here enable quick early stage ball-park design solutions to be considered and are also useful for checking finite element analysis solutions to complex problems. The conventions used in the book are in accordance with the Eurocodes especially where they provide convenient solutions that can be easily understood by students. Many of the topics such as composite beam design are straight applications of Eurocodes but with the underlying theory fully explained. The techniques are illustrated through a series of worked examples which develop in complexity with the more advanced questions forming extended exam type questions. A comprehensive range of fully worked tutorial questions are provided at the end of each section for students to practice in preparation for closed book exams. | Structural Design from First Principles

Multiscale Modeling From Atoms to Devices

Multiscale Modeling From Atoms to Devices

While the relevant features and properties of nanosystems necessarily depend on nanoscopic details their performance resides in the macroscopic world. To rationally develop and accurately predict performance of these systems we must tackle problems where multiple length and time scales are coupled. Rather than forcing a single modeling approach to predict an event it was not designed for a new paradigm must be employed: multiscale modeling. A brilliant solution to a pervasive problem Multiscale Modeling: From Atoms to Devices offers a number of approaches for which more than one scale is explicitly considered. It provides several alternatives from coarse-graining sampling of the atomic and mesoscale to Monte Carlo- and thermodynamic-based models that allow sampling of increasingly large scales up to multiscale models able to describe entire devices. Beginning with common techniques for coarse-graining the book discusses their theoretical background advantages and limitations. It examines the application-dependent parameterization characteristics of coarse-graining along with the finer-trains-coarser multiscale approach and describes three carefully selected examples in which the parameterization although based on the same principles depends on the actual application. The book considers the use of ab initio and density functional theory to obtain parameters needed for larger scale models the alternative use of density functional theory parameters in a Monte Carlo method and the use of ab initio and density functional theory as the atomistic technique underlying the calculation of thermodynamics properties of alloy phase stability. Highlighting one of the most challenging tasks for multiscale modelers Multiscale Modeling: From Atoms to Devices also presents modeling for nanocomposite materials using the embedded fiber finite element method (EFFEM). It emphasizes an ensemble Monte Carlo method to high field-charge transport problems and demonstrates the practical application of modern many-body quantum theories. The author maintains a website with additional information. | Multiscale Modeling From Atoms to Devices

Swarm Intelligence From Social Bacteria to Humans

Swarm Intelligence From Social Bacteria to Humans

The notion of swarm intelligence was introduced for describing decentralized and self-organized behaviors of groups of animals. Then this idea was extrapolated to design groups of robots which interact locally to cumulate a collective reaction. Some natural examples of swarms are as follows: ant colonies bee colonies fish schooling bird flocking horse herding bacterial colonies multinucleated giant amoebae Physarum polycephalum etc. In all these examples individual agents behave locally with an emergence of their common effect. An intelligent behavior of swarm individuals is explained by the following biological reactions to attractants and repellents. Attractants are biologically active things such as food pieces or sex pheromones which attract individuals of swarm. Repellents are biologically active things such as predators which repel individuals of swarm. As a consequence attractants and repellents stimulate the directed movement of swarms towards and away from the stimulus respectively. It is worth noting that a group of people such as pedestrians follow some swarm patterns of flocking or schooling. For instance humans prefer to avoid a person considered by them as a possible predator and if a substantial part of the group in the situation of escape panic (not less than 5%) changes the direction then the rest follows the new direction too. Some swarm patterns are observed among human beings under the conditions of their addictive behavior such as the behavior of alcoholics or gamers. The methodological framework of studying swarm intelligence is represented by unconventional computing robotics and cognitive science. In this book we aim to analyze new methodologies involved in studying swarm intelligence. We are going to bring together computer scientists and cognitive scientists dealing with swarm patterns from social bacteria to human beings. This book considers different models of simulating controlling and predicting the swarm behavior of different species from social bacteria to humans. | Swarm Intelligence From Social Bacteria to Humans

Pressure and Temperature Well Testing

Pressure and Temperature Well Testing

The book comprises two parts: Pressure and Flow Well Testing (Part I) and Temperature Well Testing (Part II) and contains numerous authors’ developments. Due to the similarity in Darcy’s and Fourier’s laws the same differential diffusivity equation describes the transient flow of incompressible fluid in porous medium and heat conduction in solids. Therefore it is reasonable to assume that the techniques and data processing procedures of pressure well tests can be applied to temperature well tests. The book presents new methods to determine the formation of permeability and skin factors from tests conducted in simulated wells designing interference well tests processing constant bottom-hole pressure tests estimation of the formation temperature and geothermal gradients from temperature surveys and logs in-situ determination of the formation thermal conductivity and contact thermal resistance of boreholes temperature regime of boreholes (cementing of production liners) and the recovery of thermal equilibrium in deep and superdeep wells. Processing and analysis of pressure and geothermal data are shown on numerous field examples from different regions of the world. The book is intended for students engineers and researchers in the field of hydrocarbon geophysics and geology groundwater searching and exploitation and subsurface environment examination.

Fluoride Removal from Groundwater by Adsorption Technology

Fluoride Removal from Groundwater by Adsorption Technology

In the Eastern corridor of Northern region of Ghana presence of high fluoride concentration in the groundwater has made many drilled boreholes unusable for drinking. Little is however known about the factors contributing to the occurrence of high fluoride in this part of Ghana and it’s spatial distribution. Treatment of the fluoride-contaminated groundwater by adsorption is also hampered by the lack of suitable adsorbents that are locally available. Based on principal component analysis and saturation indices calculations this thesis highlights that the predominant mechanisms controlling the fluoride enrichment probably include calcite precipitation and Na/Ca exchange processes both of which deplete Ca from the groundwater and promote the dissolution of fluorite. The mechanisms also include F-/OH- anion exchange processes as well as evapotranspiration processes which concentrate the fluoride ions hence increasing its concentration in the groundwater. Spatial mapping showed that the high fluoride groundwaters occur predominantly in the Saboba Cheriponi and Yendi districts. The thesis further highlights that modifying the surface of indigenous materials by an aluminium coating process is a very promising approach to develop a suitable fluoride adsorbent. Aluminum oxide coated media reduced fluoride in water from 5. 0 ± 0. 2 mg/L to ≤ 1. 5 mg/L (which is the WHO health based guideline for fluoride) in both batch and continuous flow column experiments in the laboratory. Kinetic and isotherm studies thermodynamic calculations as well as analytical results from Fourier Transform Infrared Spectroscopy and Raman spectroscopy suggest the mechanism of fluoride adsorption onto aluminium oxide coated media involved both physisorption and chemisorption processes. Field testing in a fluoritic community in Northern Ghana showed that the adsorbent is also capable of treating fluoride-contaminated groundwater in field conditions suggesting it is a promising defluoridation adsorbent. The adsorbent also showed good regenerability potential that would allow re-use which could make it practically and economically viable. Additional research is however required to further increase the fluoride adsorption capacity of developed adsorbent. | Fluoride Removal from Groundwater by Adsorption Technology
