Collecting Experiments by Bruno J. Strasser Pdf

Databases have revolutionized nearly every aspect of our lives. Information of all sorts is being collected on a massive scale, from Google to Facebook and well beyond. But as the amount of information in databases explodes, we are forced to reassess our ideas about what knowledge is, how it is produced, to whom it belongs, and who can be credited for producing it. Every scientist working today draws on databases to produce scientific knowledge. Databases have become more common than microscopes, voltmeters, and test tubes, and the increasing amount of data has led to major changes in research practices and profound reflections on the proper professional roles of data producers, collectors, curators, and analysts. Collecting Experiments traces the development and use of data collections, especially in the experimental life sciences, from the early twentieth century to the present. It shows that the current revolution is best understood as the coming together of two older ways of knowing—collecting and experimenting, the museum and the laboratory. Ultimately, Bruno J. Strasser argues that by serving as knowledge repositories, as well as indispensable tools for producing new knowledge, these databases function as digital museums for the twenty-first century.

A Select Collection of Valuable and Curious Arts and Interesting Experiments, Which Are Well Explained and Warranted Genuine and May Be Performed Easily, Safely and at Little Expense by Various Authors Pdf

Water-proof gilding and silvering.—This kind of gilding, usually termed oil gilding, being the cheapest and most durable, is in general use for gilding or silvering letters on signs, labels, &c. and may be performed as follows:—Grind one ounce of white lead and two ounces of litharge, very fine, in a gill of old linseed oil, and if convenient, add nearly one-fourth of a gill of old copal varnish, and half an ounce of stone yellow; but neither of these last, are very essential ingredients. Expose this composition to the rays of the sun for a week or more in a broad open vessel, observing, however, to keep it free from dust. Then pour off the finest part, and dilute it with as much spirits of turpentine as will make it work freely with a brush or camel-hair pencil. (Oil that will answer exceedingly well for this purpose, may sometimes be collected from the top of oil paints that have been long standing, and may be used directly, without being exposed to the sun as directed above.) Whatever letters or figures you would gild, must be first drawn or painted with this sizing, the ground having been previously painted and varnished; and when the sizing is so dry as to be hard, but yet remains slightly adhesive, or sticky, lay on gold or silver leaves smoothly over the whole, pressing them down gently with a soft ball of cotton. The most convenient manner of performing this, is to lay the leaves of gold or silver, first on a piece of deer-skin or glove-leather, and cut them into pieces of a convenient size, by drawing a smooth (not sharp) edged knife over them. Then take a small block of wood, of a triangular form, about half an inch thick, and two inches in diameter, and bind a strip of fine flannel round the edges;—breathe on this, and press it gently on a piece of the leaf, which by this may be taken from the leather, and carried to any part of the sizing where it will best fit, and to which it will readily adhere: thus the sizing may be readily covered with the leaf, very little of which will be wasted. Afterward the whole may be brushed over lightly with cotton, or a soft brush, and the superfluous gold or silver will be brushed off, leaving the letters or figures entire. When the work has thus remained two or three days, it may be rubbed with a piece of silk, which will increase its metallic lustre. Note.—It is very essential that the varnish of the ground should be thoroughly dry, that it may not be adhesive in the least degree, otherwise the leaf will stick where it should not, and materially injure the work. When plain gilding is required for vanes, balls, &c. the leaves of gold or silver may be applied to the work directly from the book, without cutting or dividing them.

On the degradation of wood pellets during pneumatic conveying: Experiments and DEM-CFD simulations by Julian Jägers Pdf

Die Zerkleinerung von Holzpellets und damit die Entstehung von Feinanteil während des pneumatischen Transports wird zusammen mit den auftretenden Druckverluste im Rahmen dieser Arbeit experimentell und numerisch untersucht. Zunächst erfolgt die Entwicklung eines empirischen Bruchmodells auf Basis von Einzelpartikelprallversuchen zur statistischen Beschreibung des Bruchverhaltens von Holzpellets in Abhängigkeit von Kenngrößen wie Partikellänge, Aufprallgeschwindigkeit und -Winkel. Die entwickelten Korrelationen werden in den hauseigenen DEM-Code des Lehrstuhls für Energieanlagen und Energieprozesstechnik der Ruhr-Universität Bochum implementiert. Gekoppelte DEM-CFD Simulationen geben detaillierte Einblicke in die Abhängigkeiten der Strömungsverhältnisse sowie des Bewegungsverhaltens und der mechanischen Belastungen der geförderten Partikel von Betriebsbedingungen und Leitungskomponenten. Die numerischen Ergebnisse stimmen qualitativ mit denen korrespondierender Experimente überein und zeigen die Erhöhung von Pelletbruch und Feinanteil durch zunehmende Förderluftströme bzw. abnehmende Pelletmassenströme und kleinere Krümmerradien. Das entwickelte Bruchmodel ermöglicht detaillierte Untersuchungen pneumatischer Fördervorgänge und die Auslegung schonender Betriebsbedingungen und Leitungskomponenten zur Reduzierung von Druckverlusten sowie Pelletbruch und Feinanteil. In the present thesis, the dependence of wood pellet degradation and fines formation during pneumatic conveying on operating conditions like air and product mass flow or shape of pipe components is investigated. Both the size reduction of the cylindrical pellets during pneumatic transport caused by mechanical impacts and the prevailing pressure losses are analysed experimentally and numerically. Single particle impact tests are performed for investigating the breakage behaviour of wood pellets including the effect of particle length, impact velocity and collision angle. Based on the empirical correlations derived, a numerical degradation model is developed and implemented into the in-house DEM code of the Department of Energy Plant and Technology of the Ruhr-University Bochum. Experimental and numerical investigations are conducted using coupled DEM-CFD simulations to obtain detailed insights into flow conditions, particle motion and the mechanical loads on the pellets during pneumatic conveying. Numerical results show good qualitative agreement with the experimentally determined degradation rates and prevailing pressure losses. The degradation model developed allows detailed investigation into wood pellet degradation and fines formation during pneumatic conveying and enables the design of pipe configurations and operating conditions to prevent particle size reduction and excessive pressure losses.

Design of Experiments by Virgil L. Anderson,Robert A. McLean Pdf

The book is written for anyone who wants to design experiments, carry them out, and analyze the results. The authors provide a clear-cut, practical approach to designing experiments in any discipline and explain the general principles upon which such design is based. The reader then can apply these theories to any specific problem in his own work. No advanced mathematics is needed to utilize Design of Experiments – the necessary statistical concepts and briefly reviewed in the first two chapters. Subsequent chapters explain why and how the design of experiments in an intrinsic part of the scientific method, what problems will be encountered by the researcher in setting up his experiment and how to deal with them, and how to accurately analyze the result in terms of the sample taken and the method used. Each chapter includes problems encountered in specific fields so that the reader can test himself on his comprehension of the material. The diversity of the applications that these problems encompass also allows the reader to grasp the basic principles that unite the statistical approach to experiment design. Researchers and students in engineering, agriculture, pharmacy, veterinary science, chemistry, biology, the social; sciences, statistics, mathematics, or any other field that requires the design, solution, and analysis of problems will find this book absolutely indispensable.

Expeditions as Experiments by Marianne Klemun,Ulrike Spring Pdf

This collection focuses on different expeditions and their role in the process of knowledge acquisition from the eighteenth century onwards. It investigates various forms of scientific practice conducted during, after and before expeditions, and it places this discussion into the scientific context of experiments. In treating expeditions as experiments in a heuristic sense, we also propose that the expedition is a variation on the laboratory in which different practices can be conducted and where the transformation of uncertain into certain knowledge is tested. The experimental positioning of the expedition brings together an ensemble of techniques, strategies, material agents and social actors, and illuminates the steps leading from observation to facts and documentation. The chapters show the variety of scientific interests that motivated expeditions with their focus on natural history, geology, ichthyology, botany, zoology, helminthology, speleology, physical anthropology, oceanography, meteorology and magnetism.
