Electromagnetic rigidity which exists in large-scale optical resonators if pumping frequency is detuned from the eigenfrequency of resonator have sophisticated spectral dependence which allows to obtain sensitivity better than the Standard Quantum Limits both for the free test mass and the harmonic oscillator.

Red blood cells (RBCs) and lysate products (erythrolysate) are consistently observed in lymph draining inflammatory reactions and from tissues subjected to trauma or surgical procedures. We determined previously that erythrolysate modulates lymphatic pumping by altering the pressures over which the lymph pump is active. The purpose of this study was to test the hypothesis that oxyhemoglobin was...

The objective of this study was to evaluate the strategies for groundwater resources management, including competition groundwater pumping, optimal control in groundwater pumping, groundwater use and tax policy, water users' participation in groundwater pumping control, and cooperation among government and water user associations in Narimany plain located in Khorasan Province. Irrigation water ...

We established a new diode array pumped Er:Yb:Glass test setup for evaluation of the laser performance and q-switch characteristics of various saturable absorber materials at 1.54um. Pumping distribution and maximum gain was analyzed. Passive q-switched laser operation was demonstrated with both U: CaF2 and Co : MgAl2O4. TEMoo Qswitch pulses with energy of 0.5mJ and pulse width of 10ns was obta...

The estimation of aquifer parameters, like transmissivity (T) and storativity (S), is vital for evaluating and managing groundwater resources. Hydrograph analysis and pumping tests are among the different methods available to estimate aquifer parameters, but pumping tests are the most commonly used. The study and data presented in this paper was conducted in the Chikaldhara Region (Amravati Dis...

Nowadays, the pump-storage power plants are a proven solution for storing electricity at large scale and offering flexibility to the power management. Therefore, the hydraulic machines are increasingly subject to off-design operation, start-up and shutdown sequences. However, the fast and frequent switching between pumping mode and generating mode presents technical challenges. In the present s...

The paper analyses the effect of electrohydrodynamic (EHD) pumping on the control of natural circulation loops (NCLs). The two major objectives of the investigation are: finding the optimal configuration of an EHD pump and demonstrating that the NCL flow direction can be inverted by exploiting the EHD phenomena. In the initial experimental set-up, we measured the static pressure rise given by a...

Groundwater microbial community samples are traditionally collected using pumping techniques optimized for groundwater chemistry assessment although the impact of groundwater pumping parameters on apparent bacterial community structures (BCS) is not really known. We therefore studied the impact of pumping lift, flow regime and tubing material on BCS, which were analyzed by terminal-restriction ...
