Improved fire-resistant coatings
Water-base coatings containing potassium silicate show improvement in areas of quick air-drying, crack, craze, and abrasion resistance, adherence, and leach resistance. Coatings are useful as thermal-barrier layers in furnaces, and as general purpose fire resistant surfaces where vapor impermeability is not a requirement

The Importance of Analytical Chemistry to Food and Drug Regulation
The first thesis this Article postulates is that the history of food and drug regulation during the past twenty centuries has been the history of the development of analytical chemistry, not the history of the development of law and regulation. Statutory law during this period has remained relatively static, while general under-standing of analytical chemistry has leapt ahead with unparalleled achievement. Increased scientific enlightenment, largely achieved through analytical chemistry, has produced every important advance in food and drug regulation. Indeed, the overwhelming success of the field of analytical chemistry has created entire scientific disciplines as well as improvement in government regulation of food and drugs.
The second thesis this Article presents is that the very nature of food and drug regulation requires that analytical chemistry will retain its central regulatory significance for the foreseeable future.The task that must be accomplished by analytical chemistry, in short, is far from completed, and stretches into the indefinite future.
Before pursuing these two theses, it is necessary to dispose of one subsidiary matter. The past few years has witnessed intense debate concerning the scope of the term analytical chemistry. AOAC has, for example, discussed changing its name because of concern that the present title is not sufficiently broad to reflect the comprehensive purposes of the scientific field it represents. The plain meaning of the words themselves, however, quite adequately describes the scope of scientific inquiry represented by this field.Chemistry is defined as [t]he science of the composition, structure, properties, and reactions of matter. Analysis, as it relates to chemistry, is defined as [s]eparation of a substance into constituents or the determination of its composition. \u27 This Article approaches the subject of analytical chemistry in this comprehensive context
The effect of wave conditions and surfer ability on performance and the physiological response of recreational surfers.
This study investigated the effects of wave conditions on performance and the physiological responses of surfers. After institutional ethical approval 39 recreational surfers participated in 60 surfing sessions where performance and physiological response were measured using global positioning system (GPS) heart rate monitors. Using GPS, the percentage time spent in surfing activity categories was on average 41.6, 47.0, 8.1, and 3.1% for waiting, paddling, riding, and miscellaneous activities, respectively. Ability level of the surfers, wave size, and wave period are significantly associated with the physiological, ride, and performance parameters during surfing. As the ability level of the surfers increases there is a reduction in the relative exercise intensity (e.g., average heart rate as a percentage of laboratory maximum, rpartial = -0.412, p < 0.01) which is in contrast to increases in performance parameters (e.g., maximum ride speed (0.454, p < 0.01). As the wave size increased there were reductions in physiological demand (e.g., total energy expenditure rpartial = -0.351, p ⤠0.05) but increases in ride speed and distance measures (e.g., the maximum ride speed, 0.454, p < 0.01). As the wave period increased there were increases in intensity (e.g., average heart rate as a percentage of laboratory maximum, rp = 0.490, p < 0.01) and increases in ride speed and distance measures (e.g., the maximum ride speed, rpartial = 0.371, p < 0.01). This original study is the first to show that wave parameters and surfer ability are significantly associated with the physiological response and performance characteristics of surfing
BMT Settings, Infection and Infection Control
Despite improvements over the past several decades, infection remains a significant risk to all haematological patients receiving therapy. Those requiring allogeneic transplant and especially those that have HLA disparity or T-cell-depleted grafts have an even higher risk of infective complications due to delayed recovery of T- and B-cell function. Early identification with prompt effective treatment is paramount to improve all patients' survival. Patient safety through robust adherence to hand hygiene and maintenance of the environment with cleaning and disinfection are the backbone of an effective preventative program. Basic nursing care and a sound knowledge base of the risks, presentation, diagnosis and treatment will improve patient care
Variable length-based genetic representation to automatically evolve wrappers
The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-12433-4_44Proceedings 8th International Conference on Practical Applications of Agents and Multiagent SystemsThe Web has been the star service on the Internet, however the outsized information available and its decentralized nature has originated an intrinsic difficulty to locate, extract and compose information. An automatic approach is required to handle with this huge amount of data. In this paper we present a machine learning algorithm based on Genetic Algorithms which generates a set of complex wrappers, able to extract information from theWeb. The paper presents the experimental evaluation of these wrappers over a set of basic data sets.This work has been partially supported by the Spanish Ministry of Science

Substantiating a political public sphere in the Scottish press : a comparative analysis
This article uses content analysis to characterize the performance of the media in a national public sphere, by setting apart those qualities that typify internal press coverage of a political event. The article looks at the coverage of the 1999 devolved Scottish election from the day before the election until the day after. It uses a word count to measure the election material in Scottish newspapers the Herald, the Press and Journal and the Scotsman, and United Kingdom newspapers the Guardian, the Independent and The Times, and categorizes that material according to discourse type, day and page selection. The article finds a number of qualities that typify the Scottish sample in particular, and might be broadly indicative of a political public sphere in action. Firstly, and not unexpectedly, it finds that the Scottish newspapers carry significantly more election coverage. Just as tellingly, though, the article finds that the Scottish papers offer a greater proportion of advice and background information, in the form of opinion columns and feature articles. It also finds that the Scottish papers place a greater concentration of both informative and evaluative material in the period before the vote, consistent with their making a contribution to informed political action. Lastly, the article finds that the Scottish sample situates coverage nearer the front of the paper and places a greater proportion on recto pages. The article therefore argues that the Scottish papers display features that distinguish them from the UK papers, and are broadly consistent with their forming part of a deliberative public sphere, and suggests that these qualities might be explored as a means of judging future media performance
