Abstract:
The function of regenerators is to use the thermal energy of the waste gases to preheat the combustion air and thereby provide better heat transfer via a high flame temperature. Satisfactory furnace operation can only be achieved if the regenerator chambers are in good condition. Today, environmental issues play a major role in the selection of regenerators and checkers refractories. The impact on the environment has been studied on 35 side-fired flat glass furnaces. Firstly, we will describe in this paper the issues raised by increased carry over and CO content observed in various furnaces with different types of checker packing such as basket weaves, box blocks and cruciforms . Secondly, we will talk about how the impact on health and waste/recycling solutions is analyzed and should be taken into consideration before ordering refractories. Finally, some new materials are now appearing on the market. The fact that China dominates magnesia production (51% of the world production) entails the rise of new raw material sources for the basic refractories used for checker bricks. Besides that, the refractories suppliers are continuously improving their materials to offer glassmakers new solutions to overcome the actual issues in the regenerators. These new sources of materials have been analyzed in R&D and are now considered as potential solutions which need further testing under industrial conditions.

Abstract:
Impulse drying technology can be applied to most primary and mixed primary/secondary cakes from pulp and paper operations. Results from the first two onsite trials illustrate some of the factors that govern dewatering including belt porosity, roll temperature, pressure, belt cleaning, ash content, sludge feed delivery, and sludge structure and type. Roll sticking is one of the most important factors that govern the application of the technology. The potential for roll sticking cannot presently be evaluated a priori. Refinements made in the unit as a result of these trials are discussed.

Abstract:
The widespread availability and affordability of voice and video recording systems allows researchers in all modes of transportation to observe, document, and study operator behavior. For example, naturalistic driving studies use technology to record discreetly everyday vehicle operations and driver behavior to understand the risk factors that contribute to unsafe situations. It has been proposed that similar technology could be used in locomotives to observe and evaluate the crew's use of controls and human factor issues. The joint (government–industry) Locomotive Voice and Video Recording (LVVR) project was convened to assess LVVR technology, document safety benefits, and identify best practices. An evaluation of safety-relevant human factors and operational issues was conducted to determine the adequacy of three types of recording systems (voice only, video only, and voice and video) to record and document locomotive crew behavior. All the LVVR systems that were evaluated, regardless of mode, allowed the identification of crews’ responses to train control signals. Although it was often possible to identify operators’ roles in the cab and their use of locomotive controls, evaluation of human factor issues—such as crew resource management, stress, fatigue, workload, situation awareness, and distraction—was less reliable. Recording modality and system-specific issues that limit the use of LVVR were identified. Collectively, the results indicate that LVVR systems that collect voice and video data and that are of sufficient technical quality to provide clear, unambiguous recordings are the most conducive to the assessment of crew operational and human factor issues.

Abstract:
Using a three-dimensional ethical role-specific model, this article considers the dual loyalty conflict between following military orders and professional codes of practice in an operational military environment when a patient soldier refuses life-saving medical treatment and where their legal capacity is questionable. The article suggests that although every competent patient has the right to refuse medical treatment even though they may die as a consequence. Ordinarily, it is unethical to exert any undue influence on a patient to accept medical treatment, in a military operational environment where attack from the enemy is likely, it may be reasonable and understandable to exert undue influence over a patient when they lack legal capacity.

Abstract:
Ceramics have long been known for their refractoriness, or ability to bear loads at elevated temperatures. However, until the 1960s, the predominant refractory ceramics were oxide-based materials such as silica, zirconia, alumina, mullite, magnesia, and their combinations, including silicates. These ceramics were, and still are, used for firebrick furnace linings, crucibles and liquid metal carrier liners, regenerators, and recuperators.However, these materials all possess some characteristic which precludes their use for very high stress, high temperature applications. Typically, the silicates form viscous liquids which allow creep, while zirconia and alumina suffer from poor thermal shock resistance, and magnesia possesses a large thermal expansion coefficient. Consequently, for heat engine applications which involve high temperatures, high stresses, sudden temperature changes (e.g., startup), and may involve the maintenance of tight operating tolerances, a new family of materials is required. The requisite properties for heat engine applications may be found in certain non-oxide materials, namely silicon nitride and silicon carbide. They possess high strength even at high temperatures, low thermal expansion coefficient, and excellent thermal shock resistance. These materials are not thermodynamically stable in air at elevated temperatures and will eventually react to form oxides. Nonetheless, they possess excellent oxidation resistance by virtue of protective silica-based glass oxidation layers.

Abstract:
This article focuses on a nonprofit, hospital-based comprehensive home infusion service in which all intravenous (IV) drugs or nutritional admixtures, professional services, supplies, and reimbursement services are performed solely by inpatient pharmacists, IV therapy nurses, and pharmacy assistants. By modifying an inpatient work load measurement system, additional staff are justified by total time for home infusion service work units. Twenty-four-hour back-up by cross-trained inpatient pharmacists and IV therapy nurses has contributed to the number of patients served by the home infusion service, which has grown steadily. A permanent and complete outpatient medical record is maintained for each patient (separate from inpatient records) in the infusion service and is available for 24-hour easy access for after-hour calls. All multidisciplinary team members participate in formal, weekly patient-care case conferences to review and update all patient therapies. Services covered, billing procedures, procedure codes, allowable charges, prior approval requirements, copayment arrangements, claims processing schedules, and related billing arrangements were first identified. The overall success of the program's reimbursement remains at 85% of charges when combining all patients. Structure, process, and outcome criteria unique to a comprehensive home care quality assurance program evolved from our high volume (total parenteral nutrition [TPN]), high risk (pain management, antibiotics), and problem-prone (TPN, pain management) therapies. Reimbursement remains the most troublesome aspect of initiating a successful hospital-based program. The success of our program depends heavily on the ability to attract and retain a highly motivated professional staff and to maintain strong referral networks with local physicians, hospital discharge planners, and other health care professionals.

Abstract:
Software reliability plays an important role in assuring the quality of a software. To ensure software reliability, the software is tested thoroughly during the testing phase. The time invested in the testing phase or the optimal software release time depends on the level of reliability to be achieved. There are two different concepts related to software reliability, viz., testing reliability and operational reliability. In this paper, we compare both types of software reliabilities to determine the optimal testing time of the software so as to minimize the total expected software maintenance cost. We consider a software has a number of clusters of modules, each having a different number of errors and a different failure rate. A hyperexponential model is employed for analyzing software reliability growth. Parameter estimation using the maximum likelihood estimation technique is also discussed. Numerical illustrations are taken to explore the effect of various parameters on reliability and maintenance cost. It is noticed that the operational reliability concept should be adopted for the software testing time problem.

Abstract:
The heavy vehicle industry includes medium-duty trucks, heavy-duty trucks, and buses. Vehicle size, driver location relative to the road, and duration of time in the vehicle distinguish heavy vehicles from the passenger car and light truck industry. During the past decade, the industry has been changing. Technological advances, as well as political, economic, and cultural forces, have combined to create a new environment. The driver has become more important in this new environment. A driver shortage and safety issues have heightened the interest in human factors and ergonomics in the heavy vehicle industry. The purpose of this symposium is to highlight some of the current human factors research in the field of heavy vehicles. While there are many possible topics to discuss, the first two papers will address vehicle design issues and the second two papers will address operational issues. Ms. Kinghorn will discuss a technique to estimate the current population of US Truck Drivers. She proposes that some of the shortcomings of the available data, such as changes in the population over the last decade and dimensions for which no data are available, can be overcome by estimating the current truck driver population from data on the general population. Mr. Reynolds will discuss the discrepancies observed between a design eyellipse location and actual driver eye locations in a small exploratory study. He will describe the primary contributor to the discrepancy, the H-point, and suggest several other potential contributors. Ms. Feyer will discuss a study on the effects of operational practices on driver fatigue. She will compare and contrast the operational practices of various segments of the long distance passenger and freight hauling industries. Her results indicate that different strategies must be applied to the passenger and freight industries to combat fatigue, even though the causes of fatigue are the same. Ms. Freund is from the US Federal Highway Administration's Office of Motor Carriers. She will discuss their plans for research concerning truck and bus driver operational regulation. Specific areas that are of interest include proficiency testing, fitness for duty, and substance abuse. She will elaborate on the program, addressing driver fatigue and loss of alertness.

Abstract:
In the last five years over 100 microfiltration (MF) and ultrafiltration (UF) drinking water plants have been installed in Europe with a combined output of some 1,500 ML/day. The impetus behind this growth is concern over drinking water quality, regulatory pressure, the rapidly declining costs of membrane systems, and consumer pressures for non-chemical treatment. Although the principal justification for membrane plants is their capacity to remove human pathogens more effectively than conventional treatment, the ability of large plants to retain an integral barrier is not well understood. Currently available technology can monitor a full-scale membrane plant for integrity against passage of bacteria and parasites but not viruses. In essence the plant operator has to rely on the membrane manufacturer – on an assumption that if the membrane is not compromised at a level of 1 to 2 μm (the current practical level of measurement) it is also not compromised for virus removal. This paper quantifies the loss of integrity that can occur from membrane fiber failure. It explains the mathematical models used to describe bypass flow through compromised fibers and correlates the results with laboratory tests. Both are compared with artificially compromised fibers in a large full-scale operating plant. Under the worst case scenario where a fiber breaks close to the pot (collection end of the filtration module or element) the relative loss of integrity between alternative process designs from a single broken fiber can differ by as much as 2 log reduction values. The analysis demonstrates the need for monitoring methodology that that can track incremental changes in integrity to allow scheduled rather than emergency maintenance. It highlights the need for regulatory authorities to approve membrane systems based on actual operating performance in preference to laboratory data.
