Lymphosarcoma: Part I

Transplantable Lymphosarcoma I N Mice

Among the 100 tumors that have been induced in this laboratory during the past year by the injection of 1: 2 : 5: 6-dibenzanthracene into mice were three lymphosarcomata. Lesions of the lymphatic system, lymphoid leukemia and lymphosarcoma have not occurred as a genetic factor in the untreated mice of the pure inbred strains used, although apparently such strains are not uncommon or difficult t...

Lymphosarcoma with Ovarian Involvement I N a Child

The patient (Chart No. 55336) was a white girl four and a half years of age.

Uveal lymphosarcoma.

LYMPHOMATOUS tumours involving the lids and orbit have been recognized and repeatedly reported in the literature for many years; intra-ocular involvement on the contrary is rare if the lymphomatous infiltrations associated with lymphatic leukaemia are excluded. Kukain (1935) and Triebenstein (1920) have each described a case of uveal lymphosarcoma complicated by secondary glaucoma, and other is...

The theory of stick-slip is developed, based on the concept of a static and dynamic coefficient of friction. The dynamic coefficient is assumed to be independent of displacement and to depend wholly on normal stress across the surface. It is also assumed to be velocity-independent. The theory predicts that the stress drop during stick-slip is independent of machine stiffness. The displacement d...
