Lamivudine monoprophylaxis for de novo HBV infection in HBsAg-negative recipients with HBcAb-positive liver grafts.
We followed the efficacy of long-term lamivudine monotherapy in preventing development of de novo hepatitis B (DNHB) in a large cohort of hepatitis B surface antigen (HBsAg)-negative recipients with grafts from hepatitis B core antibody (HBcAb)-positive donors. Recipients were observed over a long follow-up. Between July 1999 and December 2008, 45 patients (median age 54, range 19-67) who were HBsAg negative before transplantation were included in the study of monoprophylaxis with lamivudine starting on post-operative day 1, and continuing for life. Mean follow-up: 37.9 months; median 32.1 months (range 2.4-117). No suspension of therapy was reported during the study. Post-transplantation, …
Non-dimensional groups for air solar collectors
Abstract The radiant heat captured by a passive air solar collector during a day divides itself into three fractions, of which one is transmitted by conduction to the backside, one is collected by the convective air flow, and the last one is lost through glazing. Some calculations of heat transfer taking place in a collector in 24-h periodic regime have been done with different combinations of the values of the relevant thermo-physical variables. Calculation results were the fractions of energy transmitted to the internal room through the wall by conduction and with the air flow by convection, and lost through the glazing. The results give rise to a correlation among non-dimensional variabl…
Fisica tecnica. Volume II. Termodinamica
In this book some aspects of applied Thermodynamics are treated, starting from the basic notions of Physics, that are supposed to be known. This book was written as a textbook for engineering students, covering the topics of applied Thermodynamics which are most relevant to the following courses. However, the authors feel that it may also be of value for professionals as a reference or a freshen–up tool on the principles of the matter. All physical quantities are expressed in the units of the International System of Units (SI); this has made it possible to omit the units of measurement in all equations. Only few exceptions are made to this rule, where multiples or submultiples of SI units, …
