ELECTROKINETIC PHENOMENA : VII. RELATIONSHIP BETWEEN ELECTRIC MOBILITY, CHARGE, TITRATION CURVE, AND OPTICAL ROTATION OF PROTEIN
The specific rotation of egg albumin, gliadin, and gelatin (40°C.) is discussed in connection with available data on (a) mobility, (b) titration curve, and (c) osmotic pressure. It seems likely that the change in specific rotation with pH of protein solutions is proportional to the change in net charge
Quark-Lepton Symmetry In Five Dimensions
We construct a complete five dimensional Quark-Lepton symmetric model, with
all fields propagating in the bulk. The extra dimension forms an orbifold with the zero mode fermions corresponding to standard model
quarks localised at one fixed point. Zero modes corresponding to
left(right)-chiral leptons are localised at (near) the other fixed point. This
localisation pattern is motivated by the symmetries of the model. Shifting the
right-handed neutrinos and charged leptons slightly from the fixed point
provides a new mechanism for understanding the absence of relations of the type
or in Quark-Lepton symmetric models. Flavour changing
neutral currents resulting from Kaluza Klein gluon exchange, which typically
arise in the quark sector of split fermion models, are suppressed due to the
localisation of quarks at one point. The separation of quarks and leptons in
the compact extra dimension also acts to suppress the proton decay rate. This
permits the extra dimension to be much larger than that obtained in a previous
construct, with the bound TeV obtained.Comment: 12 pages, references added to match published versio
Bosonisation Excercise in Three Dimensions: Gauged Massive Thirring Model
Bosonisation of the massive Thirring model, with a non-minimal and
non-abelian gauging is studied in 2+1-dimensions. The static abelian model is
solved completely in the large fermion mass limit and the spectrum is obtained.
The non-abelian model is solved for a restricted class of gauge fields. In both
cases explicit expressions for bosonic currents corresponding to the fermion
currents are given.Comment: 11 pages, LaTeX, E-mail: [email protected]
Round Table Discussions on the Proposed Code of Judicial Conduct
The importance of lawyers and society of the ethics and the selection of judges cannot be minimized. Judges set the tone for lawyers\u27 ethics. Judicial behavior significantly influences the attitude of the lay citizens toward justice and the integrity of his government. And, if the courts are to retain their independence and influence—without either the power of the purse or the sword—our judicial officers must be beyond question in matters of ethics and impartiality. The proposed A.B.A. Code of Judicial Conduct, if widely adopted and enforced, will be a significant step toward this goal
Data and the city – accessibility and openness. a cybersalon paper on open data
This paper showcases examples of bottom–up open data and smart city applications and identifies lessons for future such efforts. Examples include Changify, a neighbourhood-based platform for residents, businesses, and companies; Open Sensors, which provides APIs to help businesses, startups, and individuals develop applications for the Internet of Things; and Cybersalon’s Hackney Treasures. a location-based mobile app that uses Wikipedia entries geolocated in Hackney borough to map notable local residents. Other experiments with sensors and open data by Cybersalon members include Ilze Black and Nanda Khaorapapong's The Breather, a "breathing" balloon that uses high-end, sophisticated sensors to make air quality visible; and James Moulding's AirPublic, which measures pollution levels. Based on Cybersalon's experience to date, getting data to the people is difficult, circuitous, and slow, requiring an intricate process of leadership, public relations, and perseverance. Although there are myriad tools and initiatives, there is no one solution for the actual transfer of that data
Monopoles and Instantons in String Theory
In recent work, several classes of solitonic solutions of string theory with
higher-membrane structure have been obtained. These solutions can be classified
according to the symmetry possessed by the solitons in the subspace of the
spacetime transverse to the membrane. Solitons with four-dimensional spherical
symmetry represent instanton solutions in string theory, while those with
three-dimensional spherical symmetry represent magnetic monopole-type
solutions. For both of these classes, we discuss bosonic as well as heterotic
solutions.Comment: 16 page
