Book Description
This report presents a cost analysis of Oxygen recovery from air. The process examined is a typical vacuum swing adsorption process. In this process, low purity Oxygen is produced. This report was developed based essentially on the following reference(s): Keywords: Pressure Swing Adsorption, PSA, VSA

Book Description
This research thesis compares the major, most feasible methods of providing the needed amounts of oxygen on the lunar surface for a future human mission. Past studies are combined to provide a comprehensive look at each process and their processing requirements (for example, the mass a processing plant requires, the speed at which the oxygen could be produced, and the cost of setting up such a processing system). There are three methods of in-situ oxygen production that will be researched: hydrothermal reduction, carbothermal reduction, and water/ice electrolysis. Transportation from the Earth is also noted as a basis of comparison. These three methods were chosen because they are the three simplest, most studied methods of regolith reduction to produce oxygen. There have been several studies done on these methods from which I base my research. Pure electrolysis is being studied because of the possibility of water ice at the lunar poles. All three processes are compared and analyzed under various lunar constraints. These constraints limit the feedstock of the system at different locations on the lunar surface. It is found that the water ice concentrations estimated at the north-pole are significantly above that needed to make ice electrolysis the most beneficial method of extraction. However, in mid-latitudes and the south-pole such a definite conclusion is not yet seen. In the south polar regions if the water ice concentration is in the lower half of the bound estimated then ice electrolysis is not the most beneficial, yet if it is in the upper half it will be at least more beneficial than the hydrothermal process, if not the most beneficial. More research must be conducted on the carbothermal system to make definite analysis quantitatively conclusive.

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
The purpose of this guidance document is for the appropriate selection procurement utilization and maintenance of oxygen concentrators. This document also focuses on recommendations for the appropriate use and maintenance of oxygen concentrators in an effort to increase the availability management and quality of oxygen concentrators and ultimately to improve health outcomes in LRS. This document is intended to serve as a resource for the planning and provision of local and national oxygen concentrator systems for use by administrators clinicians and technicians who are interested in improving access to oxygen therapy and reducing global mortality associated with hypoxaemia.

Book Description
This book covers topics of equilibria and kinetics of adsorption in porous media. Fundamental equilibria and kinetics are dealt with for homogeneous as well as heterogeneous particles. Five chapters of the book deal with equilibria and eight chapters deal with kinetics. Single component as well as multicomponent systems are discussed. In kinetics analysis, we deal with the various mass transport processes and their interactions inside a porous particle. Conventional approaches as well as the new approach using Maxwell-Stefan equations are presented. Various methods to measure diffusivity, such as the Differential Adsorption Bed (DAB), the time lag, the diffusion cell, chromatography, and the batch adsorber methods are also covered by the book. It can be used by lecturers and engineers who wish to carry out research in adsorption. A number of programming codes written in MatLab language are included so that readers can use them directly to better understand the behavior of single and multicomponent adsorption systems.
