Membrane potentials of thin nitrocellulose membranes

Abstract: The membrane potentials of thin (300–1300 A.) nitrocellulose (Parlodion) membranes have been investigated. Measurements were made in a Lucite cell by use of calomel electrodes with 0.05N KCl and 0.1N KCl. Variables having an influence on membrane structure, such as solvent polarity, temperature, and thickness, have been studied in relation to membrane potential. The range of potentials observed for Parlodion (2.1–9.2 mv.) is believed to be the result of differences in the orientation of the nitrocellulose molecules (and their accompanying electrochemically active carboxyl groups) in the membrane structure.

Could firewall rules be public – a game theoretical perspective

Abstract: Firewalls are among the most important components in network security. Traditionally, the rules of the firewall are kept private under the assumption that privacy of the ruleset makes attacks on the network more difficult. We posit that this assumption is no longer valid in the Internet of today due to two factors: the emergence of botnets reducing probing difficulty and second, the emergence of distributed applications where private rules increase the difficulty of troubleshooting. We argue that the enforcement of the policy is the key, not the secrecy of the policy itself. In this paper, we demonstrate through the application of game theory that public firewall rules when coupled with false information (lying) are actually better than keeping firewall rules private, especially when taken in the larger group context of the Internet. Interesting scenarios arise when honest, public firewalls are socially insured by other lying firewalls and networks adopting public firewalls become mutually beneficial to each other. The equilibrium under multiple-network game is socially optimal because the percentage of required lying firewalls in social optimum is much smaller than the percentage in single-network equilibrium and the chance of attacking through firewalls is further reduced to zero.

Microscopy and Imaging

Abstract: The history of research in plant anatomy started with and parallels technological inventions and advancements in microscopy. Many of the early discoveries in plant anatomy laid the groundwork for all of biology—from the very concept (and naming) of the cell (Hooke (1665) Micrographia: or some physiological descriptions of minute bodies made by magnifying glasses. With observations and inquiries thereupon. The Royal Society, London) to Brownian movement (Brown R, Philosophical Mag 4:161–173, 1828), and beyond. The light microscope has been the tool of choice for over 300 years. The transmission electron microscope (available in the early 1950s) and scanning electron microscope (late 1960s) revolutionized biological imaging in the second half of the twentieth century. Innovations in microscopy continue apace, with confocal laser scanning microscopy and computer-based image enhancement leading the way.

Six new species of micrathena (araneae, argiopidae) from south america with notes on known species

Abstract: Six new species of Micrathena are described and figured These are all selected from unassorted collections loaned by the Department of Zoology, British Museum (Natural History) and Oxford University Museum The types will be deposited in the appropriate institutions In order to further our understanding of the genus additional notes and figures on sixteen species, previously known but inadequately described, are given
