THE PROCEDURE BY EVALUATION OF DIVERS FOR THE DEEP DIVING [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists), 2014
When a diver is selected to perform a deep diving course, he has to pass a medical test and isn’t affected by the HPNS (High Pressure Nervous Syndrome). When a diver is selected to perform a deep diving course, he has to pass an evaluation stage in order

BLENDING RESPIRATORY GAS MIXTURES [PDF]

open access: yesAnnals: Series on engineering sciences (Academy of Romanian Scientists)
The binary or ternary gas mixtures used in diving can be blended either by a successive and controlled injection of the component gases into containers of constant volume, following the pressure in the containers, or by a continuous flow mixing, with ...

Diving capabilities of diving petrels

open access: yesPolar Biology, 2014
5 pages, 3 figures, 1 table, supplementary material https://doi.org/10.1007/s00300-014-1483-0 In striking contrast to the general increase in diving ability with body mass in seabirds, amongst the Procellariiformes, the deepest dives appear to be by the smallest species.

Wanted Dead or Alive? The Relative Value of Reef Sharks as a Fishery and an Ecotourism Asset in Palau [PDF]

open access: yes, 2011
Over the last 20 years, ecotourism to view and interact with marine megafauna has become increasingly popular (Higham and Lück 2008). Examples of this type of tourism include turtle and whale watching, snorkelling with seals and shark diving (Jacobson ...

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Diving in Two Marine Lakes in Croatia [PDF]

open access: yes, 2005
We describe the diving methods used for in-situ observations of the scyphozoan medusa, Aurelia sp., in two marine lakes on the island of Mljet, Croatia. Both lakes have a strong pycnocline at approximately 15 m.

Biodegradable Carbonate Nanogels Loaded with Anti MFAP‐5 siRNA for Anti‐stromal Therapy of Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
Polycarbonate nanogels enable lipid‐free delivery of anti‐MFAP‐5 siRNA into cancer‐associated fibroblasts (CAF) in hepatocellular carcinoma. In a cirrhotic murine model, this approach silences MFAP‐5, reduces fibroblast activation, and suppresses tumor growth by inhibiting NOTCH/Hes1‐driven angiogenesis. CAF‐targeted MFAP‐5 RNAi and conserved signaling

Risk of acute somatic hospital admissions among seafarers: a registry-based study in Norway

open access: yesBMJ Open
Objectives To investigate whether seafarers in Norway who were declared unfit for service at sea or received a time-limited health certificate had a higher risk of acute somatic hospital admissions compared with those who received a full health ...
