The TOTEM collaboration has developed and tested the first prototype of its Roman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of silicon detectors with strips oriented in two orthogonal directions. To measure proton scattering angles of a few microradians, the detectors will approach the beam centre to a distance of 10 σ + 0.5 mm (= 1.3(More)
Various facts are now known about the relative lymphoma resistance of a group of tetraparental AKR reversible CBA/H-T6 chimaeras derived by early embryo aggregation. Firstly, their tumour resistance is not due to the lack of the lymphomaprone AKR cells. Secondly, results showing titres of MuLV-gs antigen comparable with, and occasionally in excess of, those(More)
Leafy spurge (Euphorbia esula-virgata), a native of Eurasia, is a serious invasive weed of western grasslands of North America. It is very difficult and cost-prohibitive to control with herbicides; control by insect biological control agents and cultural practices are minimally effective in suppressing vegetative growth and seed production.

Sera from patients with nasopharyngeal carcinoma (NPC), a disease associated with Epstein-Barr virus (EBV), were found to be cytotoxic at 15% degrees C in the presence of complement for a panel of human lymphocytes, with a higher frequency than those of matched controls. The cold lymphocytotoxic antibodies (LTA) responsible for this activity have the same(More)
