...plasma cells, “myeloma” refers to a tumor of the bone marrow, and “multiple” refers to more than one area of the bone marrow being affected (Mangan, 2006, p. 64hn1). Because the disease is incurable, and because only 30 percent of patients survive longer than five years after diagnosis, living with multiple myeloma can be difficult for patients and their families (Mangan, 2006, p. 64hn1). As health care providers on the front lines of patient care, nurses must be aware of the multi-system manifestations of multiple myeloma, be able to make the assessments needed to identify and prevent complications related to the disease and its treatment regimen, and be ready to provide patients and their families with knowledge and support. In this paper, the author will first provide a full description of multiple myeloma, including etiology and risk factors, pathophysiology, diagnostic tests, and treatment. This accomplished, the author will apply the stages of the nursing process to nursing care...

...modern medical training, required his residents to be on call 362 days a year, and for almost the next hundred years the attitude of the medical establishment was more or less the same. Not that far into Halsted’s career did they find out that Halsted fueled his manic work ethic with cocaine. The way Halsted first go interested in cocaine was when he read Freud's very famous paper on cocaine. It talked about how you can use cocaine on your patients and this interested Halsted. Sadly like most doctors back then, they uses it on themselves. Halsted read various little case reports in some journals about how great cocaine was for fighting off depression or fatigue. This cocaine helped him greatly because he was now able to work none stop and have a crazy work load and not be tired. Soon he stopped going to the hospital. He stopped going to meetings. He stopped writing. The cocaine helped him with working none stop and getting no sleep for a while but it wasn’t a cure for sleep deprivation. There was a case where he was called down to see a patient at the Bellevue Hospital. It was a serious fracture, a leg fracture in a man who fell off the roof of a building. And Halsted was quite the expert at repairing these types of injuries. The bone was literally sticking out of his leg and it would have been horrible for the man if nobody fixed it soon. Halsted was so high on cocaine that he left and said that he cannot operate on this man, then went home and...

...LIQUID METAL EMBRITTLEMENT (LME) RAGHAV MOHAN Graduate Student M.S in Technical Entrepreneurship and Management University of Rochester INTRODUCTION Liquid metal embrittlement (LME) is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when tested in the presence of specific liquid metals. Generally, a tensile stress or a residual stress is needed to induce embrittlement. Many mechanisms were proposed to explain the phenomenological characteristics of LME. The significance of liquid metal embrittlement is revealed by the practical observation of several structures experiencing ductility losses and cracking during hot dip galvanizing or during subsequent fabrication. Liquid metal embrittlement effects can be observed even in solid state, when one of the metals is brought close to its melting point (e.g. cadmium-coated parts operating at high temperature). This phenomenon is known as solid metal embrittlement. OBSERVATIONS OF LME Mechanical structures are typically a space frame fabricated from parallel large diameter tubes, called chords, cross braced by smaller diameter perpendicular and diagonal tubes(e.g. sign bridge structures over freeway) .After welding, the structure is hot dip galvanized. The hot dip galvanizing process consists of submerging the structure in a bath of molten zinc. This leaves a relatively uniform zinc coating over the entire structure upon...

...Weisenberger 1 Center for Applied Energy Research, University of Kentucky, 2540 Research Park Drive, Lexington, KY 40511-8410 USA Received 7 October 2003; accepted 29 October 2003 Abstract The state of research into carbon nanotube/polymer–matrix composites for mechanical reinforcement is critically reviewed with emphasis on recent advances in CNT composite toughness. Particular interest is also given to interfacial bonding of carbon nano-tubes to polymer matrices as it applies to stress transfer from the matrix to the CNT. Potential topics of oncoming focus are highlighted. 2003 Elsevier Ltd. All rights reserved. 1. Introduction Since the documented discovery of carbon nanotubes (CNTs) in 1991 by Iijima [1] and the realization of their unique physical properties, including mechanical, ther-mal, and electrical, many investigators have endeavored to fabricate advanced CNT composite materials that exhibit one or more of these properties [2,*3,*4]. For example, as conductive filler in polymers, CNTs are quite effective compared to traditional carbon black micro-particles, primarily due to their large aspect ratios [5]. The electrical percolation threshold was recently re-ported at 0.0025 wt.% CNTs and conductivity at 2 S/m at 1.0 wt.% CNTs in epoxy matrices [6]. Similarly, CNTs possess one of the highest thermal conductivities known [*7], which suggests their use in composites for thermal management [2]. The main focus of this paper, however, will be on the use of CNTs...

...resistance, high fatigue resistance, high crack resistance and biocompatibility; it is widely used in various industries (Moiseyev, 2006). Titanium is often combined with other metals such as aluminum, vanadium, copper, iron, manganese and molybdenum to create alloys of improved grain size and hardness (Clifford, 1968). Titanium mill products: titanium foil, sheet, wire, and rod are useful in the aerospace, marine, military and other industries. Titanium powder is also used in pyrotechnics to produce silver sparks (Helmenstine, n.d.). Titanium is commonly consumed, meaning, about 95% of titanium ore extracted from the Earth is being refined into the form of titanium dioxide (TiO2), a white permanent pigment used in paints, paper, toothpaste, and plastics (Smook 2002). As titanium oxide, it is used as air purifiers (as a filter coating) to coat windows on buildings so that when titanium oxide becomes exposed to UV light (either solar or artificial) and moisture in the air, reactive redox species like hydroxyl radicals are produced so that they can purify the air or keep window surfaces clean (Stevens et. al., 1998). Also, just recently, 18-year-old Eesha Khare, a senior at Lynbrook High School, designed, synthesized and characterized a core-shell nanorod electrode capacitor (with a hydrogenated titanium dioxide core and polyaniline shell) that retained a supercapacitor's energy density and long life (Adhikari, 2013). The proponents, however, limit the scope of their research into titanium...

In order to get a brief idea of the possible results, a literature review of some of the previous papers on similar topics was done. We designed our experiment based on CCRD, but due to time constraints and the shortage of raw material we had to use the full factorial method to vary parameters of our experiments. Introduction Polyvinyl chloride, commonly abbreviated PVC, is the third-most widely produced plastic after polyethylene and polypropylene. PVC is used in construction because it is more effective than traditional materials such as copper, iron or wood in pipe and profile applications. Its properties are often modified (it can be made softer and more flexible) by the...

...EUPHORBIA FIBER REINFORCED CONCRETE Murimi, S.M. ABSTRACT This paper presents an experimental investigation on Euphorbia fibres as concrete reinforcement. The possibility of improving the mechanical characteristics of concrete through the use of reinforcement plant fibres has provoked in recent years a special interest for this new construction material, especially in those areas where plant fibres can easily be found and consequently have a low price like Kenya. In this study, the influences of addition of euphorbia fibres on properties of fresh and hardened concrete were carefully investigated. It was found out addition of these fibres in concrete significantly improved the tensile strength and the flexural strength of the composite. The test results also revealed that the compressive strength of the concrete was slightly improved. It was illustrated that plain concrete possesses a very low tensile strength, limited ductility and little resistance to cracking. Conversely, the concrete with short randomly spread euphorbia fibres in it was found to have relatively high tensile strength, high ductility and more resistant to cracking. Finally, the results presented suggest that Euphorbia fibres can be used in concrete reinforcement Keyword: Euphorbia fibres, reinforcements, concrete, cracking, compressive strength, tensile strength 1.0 INTRODUCTION Concrete has been proved to be an important construction material for more than a century all over the world.
