Die nichtinvasive Erfassung des arteriellen Pulswellensignals erlaubt Pulsmessung, Pulsoximetrie bis hin zu Gefassrisikobewertung direkt am Unterarm. Robert Couronne beschreibt zwei Modellsimulationen der Photonenausbreitung im Unterarmgewebe. Anhand gemessener Intensitaten verifiziert der Autor die erweiterte Lambert-Beer-Beziehung eines planaren Schichtenmodells und untersucht mithilfe eines Zylindermodells die Intensitatsverteilung entlang des Unterarmumfangs, wobei bevorzugte Ableitregionen identifiziert werden. Zum experimentellen Nachweis stellt der Autor den Prototyp eines optisch-transmissiven Mehrkanalsensorsystems vor und zeigt anhand von Probandenmessungen die technische Signalgewinnung und praktische Anwendbarkeit. Mit einem Klassifikationsverfahren kann die automatische Signalidentifikation sowie eine Qualitatsbewertung im Realzeitbetrieb erreicht werden. Die vorgestellten Verfahren sind dabei auf gangigen Mikrocontroller-Plattformen lauffahig."

For most of the history of scientific endeavour, science has been recorded on paper. In this digital era, however, there is increasing pressure to abandon paper in favour of digital tools. Despite the benefits, there are barriers to the adoption of such tools, not least their usability. As the relentless development of technology changes the way we work, we need to ensure that the design of technology not only overcomes these barriers, but facilitates us as scientists and supports better practice within science. This book examines the importance of record-keeping in science, current record-keeping practices, and the role of technology for enabling the effective capture, reuse, sharing, and preservation of scientific data. Covering the essential areas of electronic laboratory notebooks (ELNs) and digital tools for recording scientific data, including an overview of the current data management technology available and the benefits and pitfalls of using these technologies, this book is a useful tool for those interested in implementing digital data solutions within their research groups or departments. This book also provides insight into important factors to consider in the design of digital tools such as ELNs for those interested in producing their own tools. Finally, it looks at the role of current technology and then considers how that technology might develop in the future to better support scientists in their work, and in capturing and sharing the scientific record.
Il libro prende le mosse dai pensieri di un giovane che alla maturita liceale si trova affascinato dalla cultura dei classici greco-latini, dai rudimenti filosofici e dall impatto con le scienze fisiche e naturali. Il latino e i suoi naturalisti hanno suscitato un fervore verso la Botanica Sistematica che lo riporta a Linneo e quindi alla conoscenza del mondo naturale, all esperienza della denominazione dell esistente come conoscenza e quindi agli universali di Guglielmo d Occam. La scelta della facolta di Medicina fungera da mediazione fra la filosofia, vista come via alla verita, e la biologia con il grande mistero dell uomo nella sua dualita di mente/corpo. L incontro con il microscopio aprira la strada all approfondimento della biologia, ma anche alla ricerca dei significati e delle interpretazioni del mondo. I meccanismi della percezione, visiva in particolare, nelle articolazioni della Gestaltpsychologie, e i suoi rapporti con il mondo interiore, sia quello della memoria esplicita che della memoria implicita, sono affrontati nell esplorazione del mondo attraverso il microscopico e nella ricerca di una obiettivita scientifica. Locke e Kant, Popper e Heidegger fanno da contraltare a Ramon y Cajal, Golgi, Kandel, Heisenberg, mentre la semiotica illumina e confonde sull importanza del linguaggio per la conoscenza. Il segno e il suo riconoscimento si trasferiscono nella scienza attraverso l inter-soggettivita e il linguaggio appare come l unico modo di penetrare l esistente. Il libro si dilunga sull origine di certe denominazioni in patologia tratte dalla vita quotidiana, sull antropomorfismo spesso applicato agli oggetti del campo microscopico, sempre illustrati su base fenomenologica e psicologica.
Chemistry is an experimental subject, and what can be more stimulating than carrying out a laboratory experiment where the results are memorable either by their visual nature or by their tying together of theory. This collection of 100 chemistry experiments has been developed with the help and support of teachers throughout the UK. Each student worksheet is accompanied by a teachers' notes sheet which gives details for teachers and technicians on apparatus and chemicals, timing, context, teaching tips, background theory and answers to any questions on the student worksheets. The student worksheets are also available on the web, and can be downloaded or adapted as necessary by teachers. Classic Chemistry Experiments is designed as a teaching aid to help communicate the excitement and wonder of chemistry to students, and is ideal for both experienced chemistry teachers and to scientists from other disciplines who are teaching chemistry.

Developments in cryo-electron microscopy are creating new opportunities within structural biology and there is currently great interest in developing cryo-EM as a core tool for atomic level structural biology. Many structural techniques can give atomic or near atomic level information, but lack the ability to study proteins within a near-native environment, for example within a cellular compartment. Cryo-EM provides this opportunity, but despite the recent massive improvements in single particle cryo-EM, obtaining sub-2A structural information is still a major challenge. Cryo-electron microscopy has undergone significant developments in microscope design, camera technology and data processing regimes, but there are significant challenges that remain and opportunities to explore, many of which must be tackled by the community as a whole, rather than by individual groups. For example, sample preparation is central to electron microscopy and is currently a significant bottleneck in many experiments, and there are significant problems with ensuring the integrity of the field in terms of dealing with inherently low signal-to-noise images. This volume brings together leading researchers from the UK and the international cryo-electron microscopy community to discuss current developments and new challenges in the field. In this volume the topics covered include: Sample preparation in single particle cryo-EM Pushing the limits in single particle cryo-EM Tomographic analysis, CLEM Map/model validation and machine learning in EM
