Technological Advances in Industrial Water Safety and Security

The recent renaissance of the light microsope is fueled in part by technological advances in components on the periphery of the microscope, such as the laser as illumination source, electronic image recording (video), computer assisted image analysis and the biochemistry of fluorescent dyes for labeling specimens. After great progress in these peripheral parts, it seems timely to examine the optics itself and ask how progress in the periphery facilitates the use of new optical components and of new optical designs inside the microscope. Some results of this fruitful reflection are presented in this symposium.We have considered the polarized light microscope, and developed a design that replaces the traditional compensator, typically a birefringent crystal plate, with a precision universal compensator made of two liquid crystal variable retarders. A video camera and digital image processing system provide fast measurements of specimen anisotropy (retardance magnitude and azimuth) at ALL POINTS of the image forming the field of view. The images document fine structural and molecular organization within a thin optical section of the specimen.

Lower Voltage

The initial attractions of the high voltage electron microscope (HVEM) stemmed mainly from the possibility of considerable increases in electron penetration through thick specimens compared with conventional 100KV microscopes, although the potential improvement in resolution associated with the decrease in election wavelength had been fully appreciated for many years (eg. Cosslett, 1946)1, even if not realizable in practice. Subsequent technological advances enabled the performance of lower voltage machines to be brought closer to the theoretical limit, to be followed in turn by more recent projects which have been successful, eventually, in achieving even higher resolution with dedicated higher voltage instruments such as those at Kyoto (500KV)2, Munich (400KV)3, Ibaraki (1250KV)4 and Cambridge (600KV)5. It does not necessarily follow however that the performance of journal high voltage microscopes can be easily upgraded, retrospectively, to the same level, as will be discussed in detail below.

Family support has evolved from a buzzword of the 1990s to a concept founded in theory, mandated by federal law, valued across disciplines, and espoused by both parents and professionals. This emphasis on family-centered practices for families of young children with disabilities, coupled with federal policy initiatives and technological advances, served as the impetus for the development of Early Hearing Detection and Intervention (EHDI) programs (Nicholson & Martin, in press). White, Forsman, Eichwald, and Muñoz (2010) provide an excellent review of the evolution of EHDI systems, which include family support as one of their 9 components. The National Center for Hearing Assessment and Management (NCHAM), the Maternal and Child Health Bureau, and the Center for Disease Control Centers cosponsored the first National EHDI Conference. This conference brought stakeholders including parents, practitioners, and researchers from diverse backgrounds together to form a learning collaborative (Forsman, 2002). Attendees represented a variety of state, national, and/or federal agencies and organizations. This forum focused effort on the development of EHDI programs infused with translating research into practices and policy. When NCHAM, recognizing the critical role of family support in the improvement of outcomes for both children and families, created a think tank to investigate the concept of a conference centered on support for families of children who are deaf or hard of hearing in 2005, the “Investing in Family Support” (IFSC) conference was born. This conference was specifically designed to facilitate and enhance EHDI efforts within the family support arena. From this venue, a model of family support was conceptualized and has served as the cornerstone of the IFSC annual conference since 2006. Designed to be a functional framework, the IFSC model delineates where and how families find support. In this article, we will promote and encourage continued efforts towards defining operational measures and program components to ultimately quantify success as it relates to improved outcomes for these children and their families. The authors view this opportunity to revisit the theoretical underpinnings of family support, the emerging research in this area, and the basics of the IFSC Model of Family Support as a call to action. We challenge professionals who work with children identified as deaf or hard of hearing to move family support from conceptualization to practices that are grounded in evidence and ever mindful of the unique and dynamic nature of individual families.

Children With Hearing Loss

Background: For children with hearing loss, the benefits of FM systems in overcoming deleterious effects of noise, distance, and reverberation have led to recommendations for use beyond classroom settings. It is important that audiologists who recommend and fit these devices understand the rationale and procedures underlying fitting and verification. Objectives: This article reviews previousguidelines for FM verification, addresses technological advances, and introduces verification procedures appropriate for current FM and hearing-aid technology. Methods: Previous guidelines for verification of FM systems are reviewed. Those recommendations that are appropriate for current technology are addressed, as are procedures that are no longer adequate for hearing aids and FM systems utilizing more complex processing than in the past. Technological advances are discussed, and an updated approach to FM verification is proposed. Conclusions: Approaches to verification andfitting of FM systems must keep pace with advances in hearing-aid and FM technology. The transparency approach addressed in this paper is recommended for verification of FM systems coupled to hearing aids.

Telepractice is an exciting addition to the arsenal of speech-language pathologists for delivering services. Efficacy data continues to emerge proving the benefit of using available technology to provide assessment and treatment for persons with a variety of communication disorders, ages, and gender. In addition to providing assessment and treatment using telepractice technology, several professional issues have arisen which must be addressed before implementation of this service delivery system. Licensure and reimbursement have been at the forefront, as well they should. However, client safety is another issue that should also be addressed. Providing speech pathology services in a safe environment is a concept which may not have been considered before technological advances made it possible to provide services to someone while not being physically present.

Financial Information Systems

Financial information system is an information system that provides information to individuals or groups of people, both inside and outside the company that contains financial problems and information about the flow of money for users in the company. Financial information systems are used to solve financial problems in a company, by meeting three financial principles: fast, safe, and inexpensive.Quick principle, the intention is that financial information systems must be able to provide the required data on time and can meet the needs. The Safe Principle means that the financial information system must be prepared with consideration of internal controls so that company assets are maintained. The Principle of Inexpensive, the intention is that the cost of implementing a financial information system must be reduced so that it is relatively inexpensive.Therefore we need technology media that can solve financial problems, and produce financial information to related parties quickly, safely and cheaply. One example of developing information technology today is computer technology and internet. Starting from financial problems and technological advances, the authors make a website-based financial management application to facilitate the parties that perform financial management and supervision.Method of development application program is used Waterfall method, with the following stages: Software Requirement Analysis, Software Design, Program Code Making, Testing, Support, Maintenance.

Deposit Removal

Sootblowing technology used in recovery boilers originated from that used in coal-fired boilers. It started with manual cleaning with hand lancing and hand blowing, and evolved slowly into online sootblowing using retractable sootblowers. Since 1991, intensive research and development has focused on sootblowing jet fundamentals and deposit removal in recovery boilers. The results have provided much insight into sootblower jet hydrodynamics, how a sootblower jet interacts with tubes and deposits, and factors influencing its deposit removal efficiency, and have led to two important innovations: fully-expanded sootblower nozzles that are used in virtually all recovery boilers today, and the low pressure sootblowing technology that has been implemented in several new recovery boilers. The availability of powerful computing systems, superfast microprocessors and data acquisition systems, and versatile computational fluid dynamics (CFD) modeling capability in the past two decades has also contributed greatly to the advancement of sootblowing technology. High quality infrared inspection cameras have enabled mills to inspect the deposit buildup conditions in the boiler during operation, and helped identify problems with sootblower lance swinging and superheater platens and boiler bank tube vibrations. As the recovery boiler firing capacity and steam parameters have increased markedly in recent years, sootblowers have become larger and longer, and this can present a challenge in terms of both sootblower design and operation.
