Synergy Sted Multicolor 3d-Easysted Excel File, George Mcnamara

George McNamara

Excel 2007 file with calculations for multicolor 3D-EasySTED segmented waveplates (SWP) for fluorescence nanoscopy.

Additional explanation in my Introduction statement and in the Excel file. The Excel file uses an interpolation function available from XlXtrFun (http://www.xlxtrfun.com/XlXtrFun/XlXtrFun.htm). My thanks to Goetz Zinner, www.B-Halle.de, for communicating to me that a single 3D-EasySTED segmented waveplate can be used with multiple excitation and depletion wavelengths.

Please give Goetz Zinner full credit for recognizing that STED segmented waveplate can be manufactured to handle multiple excitation and depletion wavelengths. Different sets of wavelengths can be generated by choosing appropriate thickness quartz substrates for manufacturing the SWP. …

Self-Assembled Rippling Structure Based On Metal-Elastomer Composite For Tunable Plasmonics, Fang-Tzu Chuang

Fang-Tzu Chuang

We demonstrate that a periodic metallic wavy-structure can be easily fabricated on elastomeric polydymethylsiloxane (PDMS) substrates. The metallic wavy-structures are self-assembly formed by thermal evaporation of Ag on PDMS without any lithography processes. The size of the PDMS substrate with an aspect ratio (the ratio of length to width) higher than 2 are found to be necessary to self-assemble the one-dimensional metallic wavy-structure. The period of the wavy-structure is controllable by varing the thickness of the deposited silver film. The elastomeric- gratings can excite surface plasmon on Ag/air interfaces; the resonant wavelength can be tuned to a range of 3.5% …

Science Boot Camp For Librarians: Cpd On A Shoestring, Maxine G. Schmidt, Rebecca Reznik-Zellen

Maxine G Schmidt

Science Boot Camp for Librarians was envisioned as a casual but intensive immersion event into selected scientific subjects that employ networked computing capabilities for research and collaboration. The goal of the event is to provide librarians with networking opportunities, but more importantly, to give them some of the context and ocabulary of a discipline to enable them to better engage faculty and research scientists with regard to escience. A half-day is devoted to each of three topics chosen for that year’s camp. A local faculty member provides an overview of the research area, and a second describes a single project …

Embraining Culture: Leaky Minds And Spongy Brains, Julian Kiverstein, Mirko Farina

Mirko Farina

We offer an argument for the extended mind based on considerations from brain development. We argue that our brains develop to function in partnership with cognitive resources located in our external environments. Through our cultural upbringing we are trained to use artefacts in problem solving that become factored into the cognitive routines our brains support. Our brains literally grow to work in close partnership with resources we regularly and reliably interact with. We take this argument to be in line with complementarity or “second-wave” defences of the extended mind that stress the functional differences between biological elements and external, environmental …

Localized Shape Resonance On Silver Film Perforated By H-Shaped And More Complex Shaped Hole Arrays, Fang-Tzu Chuang

Fang-Tzu Chuang

The experimental results of light transmission through periodic array of H-shaped hole and more complicated hole which is a combination of multiple U shape are demonstrated. The observations indicate that the localized shape resonance in the longest resonant length of unfolded U-shaped part of the hole always appears. However, localized modes resonant in smaller U-shaped length don't always appear. Localized mode with non-U-shaped resonant path cannot be seen in our sample. In addition, localized mode with different order and resonant path can be excited by different polarized light.

Funding Stem Cell Research: The Convergence Of Science, Religion & Politics In The Formation Of Public Health Policy, Edward A. Fallone

Edward A Fallone

The controversy over the funding of stem cell research by the federal government is used as a case study for examining how policy choices are made in the field of public bioethics. This article examines the manner in which the decision to fund stem cell research has been influenced by the convergence of evolving scientific knowledge, conflicting religious values, and the role of elected officials in a representative democracy. The article begins by reviewing the current state of scientific knowledge concerning adult stem cells, embryonic stem cells, induced pluripotent stem cells, and the process of direct cell re-programming. Because each …

Morpho-Agronomic Analysis Of Three Roselle (Hibiscus Sabdariffa L.) Mutants In Tropical Malaysia, Noor Hasima Nagoor

Noor Hasima Nagoor

Conventional hybridization in roselle (Hibiscus sabdariffa L.) is difficult due to its cleistogamous nature of reproduction. To overcome this limitation, an intensive mutation breeding program using different doses of gamma radiation was conducted. In total, five generation of three mutants were developed from the variety 'Arab'. A number of Morpho-agronomic and physico-chemical characteristics including plant height, canopy diameter, number of branches per plant, number of fruits per branch, number of fruits per plant, weight of fruits per plant, weight of fresh calyx per plant, weight of dry calyx per plant, weight of capsule per plant of these mutants of roselle …

Science For The Environment: Examining The Allocation Of The Burden Of Uncertainty, Elisa Vecchione

Elisa Vecchione

The aim of this paper is to review the basic literature on scientific uncertainty in its statistical paradigm in order to provide enlightenment on one pivotal facet of the precautionary principle, i.e. the allocation of the burden of proof to demonstrate that an activity is not harmful to the environment. The purpose is not to explain a new theory of statistical inference, but to show how regulatory policymaking that is properly informed by scientific expertise and designed to avoid one type of error, may actually make other errors more likely and thus expose the public to danger. This problem is …

Method For Somatic Cell Nuclear Transfer In Zebrafish, Kannika Siripattarapravat, Jose Cibelli

Jose Cibelli

Somatic cell nuclear transfer (SCNT) has been a well-known technique for decades and widely applied to generate identical animals, including ones with genetic alterations. The system has been demonstrated successfully in zebrafish. The elaborated requirements of SCNT, however, limit reproducibility of the established model to a few groups in zebrafish research community. In this chapter, we meticulously outline each step of the published protocol as well as preparations of equipments and reagents used in zebrafish SCNT.
