BACKGROUND AND AIMS The mechanical properties of fiber-reinforced composite fixed partial dentures (FPDs) are af-fected by fiber impregnation. The aim of this in vitro study was to compare the fracture resistance of composite fixed partialdentures reinforced with pre-impregnated and non-impregnated fibers. MATERIALS AND METHODS Groups (n=5) of three-unit fiber-reinforced composite FPDs (23 mm...

The initial oxidation behavior of TiAl-Nb alloys was systematically investigated against the composition, temperature, and partial pressure O2 with CALculation PHAse Diagrams (CALPHAD) technique. mole fraction each product at stage corresponding temperatures predicted. products are oxides Al, Ti, Nb, order Nb. As P(O2) increases, Ti Nb move towards a high oxygen content, fractions Al gradually ...

Reduction of the size of food platform of a distal extension removable partial denture has been recommended to decrease functional load on the abutment teeth and residual ridges. The purpose of this study was to investigate the influence of shortening food platform on masticatory performance. Eight subjects unilaterally missing mandibular molars participated in the study. A unilateral design wa...

Mole is one of the first Java-based mobile agent systems. It runs on an unmodified Java virtual machine on PCs under Windows 95/NT and on workstations under several UNIX dialects. Earlier versions of Mole have provided a basic infrastructure for communication and migration of mobile agents. Version 3.0 of Mole has been strongly revised and several requests and proposals from users of the earlie...

The heats of reaction of trypsin with soybean (Kunitz), ovomucoid, and lima bean inhibitors have been measured at pH 5.0 and 10’ and 25”. All the reactions were endothermic, with AH ranging from 8.6 Cal per mole for the lima bean inhibitor to 15.3 Cal per mole for the soybean inhibitor. Equilibrium constants for the association were calculated from the dependence of residual tryptic activity up...

a twin pregnancy with a coexisting complete hydatidiform mole and a healthy fetus (cmcf) is rare. here we report three cases of cmcf with different clinical courses but similar outcome without a surviving neonate. two women required uterine evacuation before 20 weeks of gestational age because of vaginal bleeding and medical complications and the other patient underwent termination of her pregn...

a case report of the relatively rare condition of a primary hydatidiform mole in the fallopian tube is presented. key words; hydatidiform mole fallopian tube.

tubal pregnancies are common but presence of hydatidiform mole in tube is a rare entity. a woman of 53years presented with acute abdomen, preoperative pregnancy test was positive and ultrasonography suspected the case as hydatidiform mole in right tube. the patient was treated with total abdominal hysterectomy with bilateral salpingo-oophorectomy as her family was completed. subsequent histopat...

The seasonality of wild caught Cape mole-rats was investigated, focusing on endocrine, neuroendocrine and neuroanatomical parameters. The Cape mole-rat reproduces only during the winter rainfall period of the western Cape Province. Interestingly, the gonadal steroid hormones do not show any significant seasonal patterns in either males or females. In addition, the pituitary does not exhibit a r...
