This work can be considered as an effort to recognize the relationships between the drawdown and recovery data for the aquifer system, and instead of separated two graphs including Cooper – Jacob for the pumping test and Theis recovery straight line methods, Elhag (2014) innovational simplified solution agrees with more complicated solutions, and useful for determine aquifer parameter values in...

In this seminar we present the structure, operating regime and use of solid state laser with passive Qswitch. We give a description and comparison of two basic concepts of optical pumping, the lamp pumping and the diode pumping. Finally we present the Q-switch theory and more precisely passive Q-switch theory.

This study evaluates the in-situ stress field and the potential risk of fault reactivation and seal breach in the Mutineer and Exeter fields, Australian North West Shelf. Stress determinations are undertaken using pumping pressure test, rock mechanical, and log data from twelve wells. Subsequent geomechanical modelling uses the stress data to assess pore pressure changes that may induce slip on...

Sodium pumping rhodopsins (NaRs) are a unique member of the microbial-type I rhodopsin family which actively transport Na+ and H+ depending on ionic condition. In this study, we surveyed 12 different NaRs from various sources of eubacteria for their electrophysiological as well as spectroscopic properties. In mammalian cells several of these NaRs exhibited a Na+ based pump photocurrent and four...

OBJECTIVES Primary: to compare sequential and simultaneous breast pumping on volume of milk expressed and its fat content. Secondary: to measure the effect of breast massage on milk volume and fat content. DESIGN Sequential randomised controlled trial. SETTING Neonatal intensive care unit, North Staffordshire Hospital NHS Trust. SUBJECTS Data on 36 women were analysed; 19 women used simul...

In this paper, we propose an approach to design and implementation of VLSI circuits free of electrical supply and power rails. With this approach, the circuits can be made to use the power carried by the incident light for supply, control, and optical charge pumping. The circuits can be fabricated in a standard CMOS technology without additional process. A test circuit involving basic gates and...
