The present study investigates the effect of de-sanding (recycling system) on bearing capacity bored piles. Full-scale models were conducted two groups piles, first group was implemented without using this system, and second recycling system. All piles tested by static load test, considering time factor for which implemented. test results indicated a significant clear difference in when use sys...

The effect of altering uterine space available to developing conceptuses on placental and endometrial protein secretion and endometrial 3 H-thymidine incorporation on Days 25 and 35 of gestation was tested. Gilts bred at estrus (Day 0) were laparotomized on Day 4, and the uterine horn ipsilateral to the ovary with the most ovulations was ligated midway between the uterine tip and uterine bifurc...

Extensive Monte-Carlo simulations were performed to evaluate the excess number of clusters and the crossing probability function for three-dimensional percolation on the simple cubic (s.c.), face-centered cubic (f.c.c.), and bodycentered cubic (b.c.c.) lattices. Systems L × L × L′ with L′ >> L were studied for both bond (s.c., f.c.c., b.c.c.) and site (f.c.c.) percolation. The excess number of ...
