Abstract Pennatulaceans (Octocorallia: Pennatulacea) are among the most dominant octocoral species living in soft bottom communities. Some of them cosmopolitan and have been recorded all seas oceans world, from shallow waters up to about 6260 m deep. In present study, we try find answers questions biogeographical distribution sea pens including recently described species. We also evaluate diver...

Here, a brief history of the development ballpoint/rollerball pen and fountain is presented. Their principle operation analogous that multipart microfluidics-type devices, where capillarity–gravity drives ink, complex fluid, to flow in confinement micrometer-sized canal or lubricate ball rotating socket. The differences operational writing principles versus are discussed. pen’s manner was monit...

A clinical study was undertaken to compare the surface microbial contamination associated with pens constructed of either a copper alloy or stainless steel used by nurses on intensive care units. A significantly lower level of microbial contamination was found on the copper alloy pens.

In this paper we describe CO2-PENS, a comprehensive system-level computational model for performance assessment of geologic sequestration of CO2. CO2-PENS is designed to perform probabilistic simulations of CO2 capture, transport and injection in different geologic reservoirs. Additionally, the long-term fate of CO2 injected in geologic formations, including

Percutaneous electrical nerve stimulation (PENS) and percutaneous neuromodulation therapy (PNT) are therapies that combine the features of electroacupuncture and transcutaneous electrical nerve stimulation (TENS). PENS is performed with a few needle electrodes while PNT uses very fine needle-like electrode arrays that are placed in close proximity to the painful area to stimulate peripheral sen...
