...2013-14 Advanced Environmental Technologies 2013-14 Holly Cross Athletic Facility Decontamination Analysis Cleaning vs. Disinfecting Introduction Cleaning and disinfecting of public transportation is a matter of technique, coupled with the proper cleaning agents. To insure that cross contamination of harmful microbes does not occur, certain steps need to be followed to take cleanliness down to the microscopic level, where the cause of the problem actually originates. Current practices of popular cleaners often instruct the user to spray on, wait 30 seconds, and wipe. They also do little to stop cross contamination as the user moves from one container to the next. For containers, airplanes, and intermodal vehicles that go all over the world, the simple act of “cleaning” with a less powerful agent could actually be the cause of a disease jumping from one country to the next. The current practices of using alcohol-based Simple Green, or similar products, instead of the more powerful chlorine dioxide could be a legal problem due to the to the lack of disinfecting properties required by insurance and governing policies. School buses play a major role in the intermodal world we live in. The public transportation network moves millions of people around the world in vehicles that are prime targets for the growth of microbials such as viruses, bacteria and fungi. About Microbes within Athletic Facilities Microbial populations of viruses, bacteria, and fungi are among...

...concrete deterioration and accelerated rebar corrosion, basement dampness can ruin expensive electrical and mechanical equipments, which are often located in basement space; can increase maintenance requirements through frequent repainting or cleaning to combat mould growth; and can make affected areas uninhabitable or even unusable due to poor air quality. In selective problem areas, the usual approach to the treatment of water intrusion problems is to 'trench and drain', in other words, to excavate and expose the wall area and the base of the foundation, to replace waterproofing on the wall surface, and to install a drain tile system around the building or affected area. Other areas, such as floors, are untreatable using conventional methods. Electro-osmotic pulse (EOP) technology offers an alternative solution that can mitigate some water-related problems from the interior of affected areas without the cost of excavation. Further, by lessening water seepage through concrete walls and floors, indoor humidity is reduced, thereby alleviating corrosion damage to mechanical equipment, lessening mould problems, and enhancing indoor air quality. 1.2 Electro-Osmotic Flow If ions of one sign are preferentially adsorbed at a solid solution interface, a net charge or electric potential difference develops across the interface. This phenomenon is referred to as electro osmosis. It was found that when a potential difference is applied to electrodes immersed into an electrolyte...

...At this time, unfortunately, a convergence in terminology has not been forthcoming and, hence, a definition of the term Micro-Machining to be implied in the context of this assessment is in order. In principle, one may take two viewpoints:(1) The first viewpoint may define Micro-Machining as the collection of all cutting operations that are performed on micro/meso-scale components and products that fall into the 100 μm to 10,000 μm size range as shown in the figure below. The Micro-Machining regime is characterized by the requirement of producing high accuracy complex geometric features in a wide variety of materials in the above-defined size range. These requirements impose the use of considerably downsized tooling (micro-tools, e.g. endmills in the 50 to 500 micron diameter range), small undeformed chip thicknesses and feedrates (submicron to a few microns) and speed settings (50K to 200K RPM might not be uncommon) that would be considered technologically infeasible at the conventional macro-scale. As a consequence, the principal distinction between Macro and Micro-Machining operations emerges and manifests itself as the dominance of ploughing and rubbing phenomena at the cutting edge over shearing and the necessity to take micro-structural effects into consideration. (2) The second viewpoint approaches the definition of the Micro-Machining regime from the standpoint of the magnitude of the undeformed chip thickness being removed in the cutting process. It is difficult to define...

EXECUTIVE SUMMARY Founded in 2015, Sigma Medical Technologies (SIGMA) is located in the SE region of Albuquerque, New Mexico, in the Sandia Industrial Park area east of Kirtland Air Force Base on Eubank Blvd. SIGMA, owned by Dr. Remy and Mr. Bob Sachs (of TEAM Technologies), serves as the patent holder and developer of “Ozone”. UNM Anderson has been contracted to provide an expeditionary marketing study. Ozone offers an invasive, defined space; gas based delivery system (generated by the product) to kill all living organisms in a room. It provides an affordable elimination and sterilization system for use by the Medical industry. It provides an additional layer of security against concealed germs, bacteria, and viral threats (pathogens). It may even be the cost effective solution to deliver solution based field units to disease hot spots that are engineered for quick and easy “Ozone” sterilization. The technology offers a “whole room” elimination solution (fills available defined space and kills pathogens) as opposed to standard “surface” based elimination systems (based on chemical wipe down style cleaning). Dr. Remy and his supportive team have a...

...The Quantity vs. Quality in Special Forces Review of Literature Carlos Falcón Saldaña MBA 525 Abstract Special Forces (SF), or more comely called “Green Berets” have a long and prestigious historical roots that stem from the elite Army formations of World War II and the Office of Strategic Service (OSS). In fiscal year 2015, the Army is looking for about 3,000 candidates to attend Special Forces Assessment and Selection, officials from the Special Operations Recruiting Battalion (SORB) said. Recruiters are seeking about 2,000 active-duty enlisted soldiers, 1,540 new recruits (for the 18X program), and about 400 active-duty officers. (Tan, 2015) With the US Army’s draw down and many SF Soldiers getting out for various reasons (Retirement, Medical Discharge, Career Opportunities) the US Army had to do something and something quick to keep the number of SF soldiers in the ranks. The re-birth of an old program seem to be the solution for this problem. This paper will identify the Quantity vs. Quality in Special Forces and in the SF Soldiers and identify why this program was “Moth-Balled” in the first place. Chapter I Introduction Introduction Special Forces (SF), Green Berets were first formed from the Office of Strategic Service (OSS) back from WWII. The OSS was formed in World War II to gather strategic intelligence and conduct operations behind enemy lines in support of resistance groups in Europe and the Far East. After the war, individuals such as Colonel Aaron...

LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital...

Reconstructing Phylogenies • 1859-1950- No coherent empirical methods • 1950-1966- Emergence of Phylogenetic Systematics • Phylogeny by discovery of the order of evolutionary innovation Ribotyping • Fingerprinting or sequencing RNA • Many diseases have unknown causes • However, diseased tissues can be ribotyped. (Wiley Death Fish) • This process involves extracting DNA from diseased tissues and then sequencing the DNA that codes for rRNA. • If a disease agent such as a bacteria is present, then we will get ribosomal DNA sequences from the host (you) and the bacteria (the infection agent). Ribotyping: Phylogeny matching • Once we have the rDNA sequences, we can plug them into a sequence matrix of all life and see where our unknowns appear on the tree of life. Our Food Chain • Some products are easy to identify, but others are not. • A slab of fish fillet from a sea bass looks like a slab of sih fillet from a farmed Asian catfish. • But the sea bass costs $10/pound while the Asian catfish...
