The module was developed as an elective to give motivated senior dental students an opportunity to expand their horizons in planning oral rehabilitation. It comprised one tutor and 12 students, from five universities world-wide, communicating on the World Wide Web (WWW), to develop oral rehabilitation plans for simulated patients. Trigger material came from one of two Case Profiles and consisted of diagnostic casts and details of the clinical and radiographic examination in WWW/CD-ROM form. No background material was supplied as to the "patient’s" age, sex, history or main concern(s). Students worked in groups of three, each student from a different location. Individual students were given a role within the group: "Patient", who developed a "personal background" belonging to the trigger examination material, "Academic" who identified state-of-the-art treatment options available for the dental treatment needs identified by the group and "General Practitioner" who tailored these options to the "patient’s" needs and wants. Student feedback focused on their perception of their experience with the program in response to a questionnaire comprising 11 structured and four "open" questions. All students felt that the program increased their confidence in planning oral rehabilitation. Ten students felt that the "best thing about the program" was the interaction with students from other universities and the exposure to different philosophies from the different schools. Eight students mentioned their increased awareness of the importance of patient input into holistic planning. Under the heading "What was the worst thing", students cited some technical hitches and the snowball effect of two sluggish students who were not identified early enough and thus impacted negatively on the working of their groups. Student feedback showed that the module succeeded in its aims but needed modification to improve the logistics of working with an extended campus. Minimize

The quantum consistency of sigma–models describing the dynamics of extended objects in a curved background requires the cancellation of their world–volume anomalies, which are conformal anomalies for the heterotic string and SO(1, 5) Lorentz–anomalies for the heterotic five–brane, and of their ten dimensional target space anomalies. In determining these anomalies in a D = 10 Lorentz–covariant back–ground gauge we find that for the heterotic string the worldvolume anomalies cancel for 32 heterotic fermions while for the conjectured heterotic five–brane they cancel for only 16 heterotic fermions, this result being in contrast with the string/five– brane duality conjecture. For what concerns the target space anomalies we find that the five–brane eight–form Lorentz–anomaly polynomial differs by a factor of 1/2 from what is expected on the basis of duality. Possible implications of these results are discussed. 1 Minimize

The computation of κ-anomalies in the Green-Schwarz heterotic superstring sigmamodel and the corresponding Wess-Zumino consistency condition constitute a powerful alternative approach for the derivation of manifestly supersymmetric string effective actions. With respect to the beta-function approach this technique presents the advantage that a result which is obtained with the computation of beta-functions at n loops can be obtained through the calculation of κ-anomalies at n − 1 loops. In this paper we derive by a direct one-loop perturbative computation the κ-anomaly associated to the Yang-Mills Chern-Simons threeform and, for the first time, the one associated to the Lorentz Chern-Simons threeform. In the calculation we shall use a convenient set of constraints for the pure N = 1, D = 10 supergravity theory which is algebraically identical to the standard set of constraints for the pure N = 1, D = 10 super Yang-Mills theory. Contrary to what is often stated in the literature we show that the Lorentz κ-anomaly gets contributions from the integration over both the fermionic and bosonic degrees of freedom of the string. A careful analysis of the absolute coefficients of all these anomalies reveals that they can be absorbed by setting dH = α′ 4 (trF 2 − trR 2), where α ′ is the string tension, the expected result. We show that this relation ensures also the absence of gauge and Lorentz anomalies in the sigma-model effective action. Moreover, the consistency condition of the κ-anomalies ensures the closure of the SUSY algebra in the Bianchi identities. We evidenciate the 1 Supported in part by M.P.I.

Intersecting M2 – and M5–branes

If an M2–brane intersects an M5–brane the canonical Wess–Zumino action is plagued by a Dirac–anomaly, i.e. a non–integer change of the action under a change of Dirac–brane.

We show that this anomaly can be eliminated at the expense of a gravitational anomaly supported on the intersection manifold. Eventually we check that the last one is cancelled by the anomaly produced by the fermions present. This provides a quantum consistency check of these intersecting configurations.

Generically an M2–brane and an M5–brane in eleven dimensions do not intersect, but for exceptional configurations the intersection may be non empty. If the intersection manifold is even–dimensional it is plagued by gravitational anomalies due to chiral fermions. We show that these anomalies are cancelled by a new sort of inflow mechanism and we argue, therefore, that such exceptional configurations are physically allowed. Minimize

Seven–Superform Gauge Fields in N=1, D=10 Supergravity and Duality ∗

Description:

We present a formulation of N = 1, D = 10 Supergravity–Super–Maxwell theory in superspace in which the graviphoton can be described by a 2–form B2 or a 6–form B6, the photon by a 1–form A1 or a 7–form A7 and the dilaton by a scalar ϕ or an 8–form ϕ8, the supercurvatures of these fields being related by duality.

We present a formulation of N = 1, D = 10 Supergravity–Super–Maxwell theory in superspace in which the graviphoton can be described by a 2–form B2 or a 6–form B6, the photon by a 1–form A1 or a 7–form A7 and the dilaton by a scalar ϕ or an 8–form ϕ8, the supercurvatures of these fields being related by duality. Duality interchanges Bianchi identities and equations of motion for each of the three couples of fields. This construction envisages the reformulation of D = 10 Supergravity, involving 7–forms as gauge fields, conjectured by Schwarz and Sen, which, upon toroidal compactification to four dimensions, gives the manifestly SL(2, R)S invariant form of the heterotic string effective action.
