Measurement While Drilling (MWD) is an in situ technique for the assessment of ground conditions. It records drilling parameters a machine when its drill bit penetrating into new geomaterials below bottom hole. Its penetration rate along hole depth, however, has various random variations. Such variations are inconsistent with fact that have piece-wise homogeneity. Many methods been adopted to f...
Peritoneal dialysis (PD) has been intensively offered at our centre to patients (pts) with end-stage renal disease (ESRD) from 2000, and the number of PD pts was noticed to raise. We aimed to analyse the PD population from the aspect of penetration and peritonitis rate during eleven years. Cumulative number of new RRT pts was 378 during the study period. We found high PD penetration rate: 53% (...
The present study examined the determinants of the penetration and accumulation of [(3)H]paclitaxel (12-12,000 nM) in three-dimensional histocultures of patient tumors and of a human xenograft tumor in mice. The results showed 1) significant and saturable drug accumulation in tumors, 2) extensive drug retention in tumors, and 3) a slower penetration but a more extensive accumulation in the xeno...
One of the stumbling blocks for implementation of Vehicular Ad Hoc Networks is the penetration rate: the percentage of vehicles that have the communication equipment installed. As the equipment deployment is unlikely to happen instantaneously, it is important to explore the performance gains achievable at low penetration rates. This especially pertains to safety applications, which are expected...
Understanding factors that affect the severity of a juvenile-stranger sexual assault has implications for crime prevention, and potentially, the assessment and treatment of juvenile sex offenders. This study investigated how victim characteristics and the number of suspects affected the use of physical violence and weapons and the occurrence of penetration in 495 allegations of sexual assault c...

Penetration of anticancer agents to cells distant from the vascular system is required for efficacy of cancer chemotherapy against solid tumors. Many solid tumors have a poorly formed blood vascular system with variable rates of blood flow and much larger intercapillary distances than those found in normal tissues. The requirement for drugs to penetrate several layers of tissue might pose a bar...
The rapid-growth of smartphones with embedded navigation systems such as GPS modules provides new ways of monitoring traffic. These devices can register and send a great amount of traffic related data, which can be used for traffic state estimation. In such a case, the amount of data collected depends on two variables: the penetration rate of devices in traffic flow (P) and their data sampling ...
