The purpose of this paper is to give conditions for the existence and uniqueness positive solution a rather general type elliptic system Dirichlet problem on bounded domain Ω in R n . Also considered are effects perturbations coexistence state uniqueness. techniques used super-sub solutions method, eigenvalues operators, maximum principles, spectrum estimates, inverse function theory, theory. a...

Levy, Stuart B. (Institut du Radium, Paris, France). Isologous interference with ultraviolet and X-ray irradiated bacteriophage T(2). J. Bacteriol. 87:1330-1338. 1964.-Qualitative and quantitative analysis of the interference capacity of an irradiated T(2) bacteriophage was made with ultraviolet and X-ray irradiation. Two different effects were found to explain the total interference picture in...

Two groups of four-year survivors with acute lymphoblastic leukaemia (ALL) are compared: an 'old' series consisting of 83 patients diagnosed before 1968, and a 'new' series of 366 patients included in Medical Research Council trials (UKALL I-III) and diagnosed in 1970-4. Both series differed significantly from a group of ALL patients who survived less than four years in having lower total leuco...

Peritoneal metastasis is a significant clinical challenge; life expectancy following diagnosis is usually very short. Surgical cytoreduction with HIPEC is being used with increasing frequency in selected patients; most outcome data have shown that prolonged median survivals can be observed in selected patients. This review summarizes the published data related to outcome and quality of life aft...
