Abstract Image
Since seed coating with neonicotinoid insecticides was introduced in the late 1990s, European beekeepers have reported severe colony losses in the period of corn sowing (spring). As a consequence, seed-coating neonicotinoid insecticides that are used worldwide on corn crops have been blamed for honeybee decline. In view of the currently increasing crop production, and also of corn as a renewable energy source, the correct use of these insecticides within sustainable agriculture is a cause of concern. In this paper, a probable—but so far underestimated—route of environmental exposure of honeybees to and intoxication with neonicotinoid insecticides, namely, the atmospheric emission of particulate matter containing the insecticide by drilling machines, has been quantitatively studied. Using optimized analytical procedures, quantitative measurements of both the emitted particulate and the consequent direct contamination of single bees approaching the drilling machine during the foraging activity have been determined. Experimental results show that the environmental release of particles containing neonicotinoids can produce high exposure levels for bees, with lethal effects compatible with colony losses phenomena observed by beekeepers.

We present a graphene-based ballistic diode, which is able to rectify an incident signal due to an oblique gate positioned between the two terminals of the device. The operating point of the diode can be controlled by the applied gate voltage, whereas the current-voltage dependence of the device can be changed by varying the inclination angle of the gate. In particular, the ideality factor of the graphene-based diode can take values higher or lower than 1 by modifying this inclination angle. The rectifying properties of the graphene diode are thus tunable, in deep contrast with semiconductor-based diodes.

    Opel's GaAs Poet Technology 100 GHz Clock Speed

    The Planar Optoelectronic Technology (POET) semiconductor platform was developed by OPEL Defense Integrated Systems (ODIS Inc) of Shelton, CT. It is a unique and patented Group III-V materials system that supports monolithic fabrication of ICs containing active and passive optical elements, together with high-performance analog and digital elements. An economical integration of many optical devices together with dense, high-speed analog and high-speed, low-power digital elements are possible in monolithic ICs.

    I got to see the IBM demonstration of how their tracking system works.  It can monitor the doctor to make sure he washes his hands for the minimum require amount of time before he touches a patient, the location of a patient, whether he falls, etc. It seems like a lawyer’s agenda to deal with civil law suits. The Goths in their legal system had a more direct way of dealing with the excessively litigious nature of their society.

    Do not be afraid.
    I walk beside you.
    Come take my hand.
    I hold you near in my arms.
    Can you dare to believe.
    Lower your walls.
    I will give you peace.

    Because I love you just as you are.
    Oh, I want to give you everything I have.
    Oh, let me hold you when you are weak.
    For you mean everything to me.

    Do not be afraid.
    I walk beside you.

    Now I am yours
    And now I can breathe.
    Here I remain.
    For here will I shall stay.
    Look at us now.
    Life is ours.
    Do you see the future that we,
    That we will make.

     Because I love you just as you are,
    and I want to give you everything I have.
    Oh, let me hold you when you are weak
     for you mean everything to me.

    Yes, I will love you just as you are.

    Here is another article I would like to read if I had the $32.00.

    Designer Dirac fermions and topological phases in molecular graphene

    Journal name:
    Date published:
    (15 March 2012)
    Published online

    The observation of massless Dirac fermions in monolayer graphene has generated a new area of science and technology seeking to harness charge carriers that behave relativistically within solid-state materials1. Both massless and massive Dirac fermions have been studied and proposed in a growing class of Dirac materials that includes bilayer graphene, surface states of topological insulators and iron-based high-temperature superconductors. Because the accessibility of this physics is predicated on the synthesis of new materials, the quest for Dirac quasi-particles has expanded to artificial systems such as lattices comprising ultracold atoms2, 3, 4. Here we report the emergence of Dirac fermions in a fully tunable condensed-matter system—molecular graphene—assembled by atomic manipulation of carbon monoxide molecules over a conventional two-dimensional electron system at a copper surface5. Using low-temperature scanning tunnelling microscopy and spectroscopy, we embed the symmetries underlying the two-dimensional Dirac equation into electron lattices, and then visualize and shape the resulting ground states. These experiments show the existence within the system of linearly dispersing, massless quasi-particles accompanied by a density of states characteristic of graphene. We then tune the quantum tunnelling between lattice sites locally to adjust the phase accrual of propagating electrons. Spatial texturing of lattice distortions produces atomically sharp p–n and p–n–p junction devices with two-dimensional control of Dirac fermion density and the power to endow Dirac particles with mass6, 7, 8. Moreover, we apply scalar and vector potentials locally and globally to engender topologically distinct ground states and, ultimately, embedded gauge fields9, 10, 11, 12, wherein Dirac electrons react to ‘pseudo’ electric and magnetic fields present in their reference frame but absent from the laboratory frame. We demonstrate that Landau levels created by these gauge fields can be taken to the relativistic magnetic quantum limit, which has so far been inaccessible in natural graphene. Molecular graphene provides a versatile means of synthesizing exotic topological electronic phases in condensed matter using tailored nanostructures.

    Ära Till Ditt Namn

    I wish they would sing this song again at surfers church.

    Då Din frid kommer över mig
    Ära till Ditt namn.
    Ära till Ditt namn

    På de vägar jag ej förstår
    Genom öken och ödemark
    Ära till Ditt namn
    All välsignelse Du ger mig
    Tackar jag Dig för
    Och när mörkret sakta faller
    Min röst Du hör

    Då solens strålar värmer mig
    Då livets glädje fyller mig
    Ära till Ditt namn
    Ära till Ditt namn

    På en väg märkt av lidande
    I försakelsens dunkla natt
    Ära till Ditt namn
    Du ger och tar igen
    Du ger och tar igen
    Mitt hjärta sjunger ut
    Ära till Ditt namn

    Is North korea performing Nuclear Weapons Tests for Iran?

    Telltale Isotopes Hint at North Korea Weapons Test Science 10 February 2012: 643.DOI:10.1126/science.335.6069.643-a

    The paper, Radionuclide Evidence for Low-Yield Nuclear Testing in North Korea in April/May 2010, is authored by Lars-Erik De Geer, Research Director at the Swedish Defence Research Agency, Stockholm.

    This book is very interesting to me at least:

    Innovation Hubs

    Can you imagine two groups in the government ever cooperating with each other, much less working together? This video says some will be. This is the most positive sign I have seen that the government might improve.

    Video Games versus Training Systems

    The government has spent a fortune developing training systems.  Users however prefer video games and often do not use the training systems.  This is the only video I have seen that points out the difference between the two. Video games provide an entertainment environment and not a realistic or instructive training environment. The is another difference in that many training systems are intended to be integrated with real systems. It is fantastic that NASA supports education in this way.

    $89.00 a year to view NASA's Section L2 website. Is that fair?

    Vocals: Helene Fung, Keegan Monteiro

    We were born connected to the land
    Through the land, we're all connected to each other
    Hand in hand, we can make this world a better place
    Improving people's lives
    Our lives have been changed by technology
    Tomorrow, the future will be brighter
    Hand in hand, so many people will benefit
    A new day has dawned for us
    We have a duty (Put our minds together)
    To help each other (We can travel all the way)
    Through technology (and with liberty),
    we can solve problems
    We have a duty (Let our hearts beat as one)
    Since we're born to care for each other
    Together, we can change the world
    Together, we can change the world
