The work consists of the development a market-friendly 600 W photovoltaic battery-less water pumping system. system is composed four 280 Wp solar panels, an auxiliary 10 panel, three-phase converter and ½ horsepower (hp) submersible pump. electronic stage involves resonant DC-DC in series with voltage source inverter. novelties this are related to use fixed duty-cycle frequency for application,...

Intraocular pressure, resulting from the balance of aqueous humor (AH) production and drainage, is the only approved treatable risk factor in glaucoma. AH production is determined by the concurrent function of ionic pumps and aquaporins in the ciliary processes but their individual contribution is difficult to characterize experimentally. In this work, we propose a novel unified modeling and co...

HPEAK: A COOL TOOL FOR ANALYZING HEAT PUMPS Heat pumps are getting smarter. Some of the newest models not only heat and cool your home but provide hot water as well. But how do these advanced systems affect energy consumption and are they cost effective? To get some answers, NIST researchers developed a computer program to evaluate the performance and economics of conventional and advanced heat...

An estimator identifying the flow rate through a rotary blood pump was developed. This estimation algorithm uses the pump current and speed signals to estimate the blood flow rate through the pump. The algorithm was derived based on the force balance between the electric torque generated by the motor and the load torque, including the mechanical losses. The corresponding estimator parameters we...

Abstract The fate of carbon while passing through the rocky subseafloor ocean has direct implications on global cycle now and over geologic time, as well abundance distribution life. Many organic geochemical studies require larger volumes fluids than traditional hydrothermal samplers can provide, also rigorous steps to be taken prevent contamination. Hydrothermal Organic Geochemistry (HOG) samp...

Integrated Ocean Drilling Program borehole CORK (Circulation Obviation Retrofit Kit) observatories provide long-term access to hydrothermal fluids circulating within the basaltic crust (basement), providing invaluable opportunities to study the deep biosphere. We describe the design and application parameters of the GeoMICROBE instrumented sled, an autonomous sensor and fluid sampling system. T...

This paper investigates the removal efficiency of a honeycomb electrostatic precipitator (ESP) applied to control particulate matter (PM) emissions from small-scale boiler with combustion lignite and hard coal. The specifics precipitation boilers are discussed, design principles for relevant ESPs presented used. ion-induced nucleation sulfuric acid occurred, causing drastic penetration 19 nm pa...
