Exploring beneath the PIG Ice Shelf with the Autosub3 AUV [PDF]
On 31st January 2009, two numbers: “range and bearing” flashing up on a laptop screen, indicated that Autosub3 had returned from its last mission beneath the Pine Island Glacier (PIG) Ice Shelf in the Western Antarctic.

Measurements of ice-ice friction coefficients at low sliding velocities
非回転式の摩擦測定器を製作し,低温室(-10℃)で滑り速度10-7m/s~10-3m/sおよび垂直応力123,245,368kPaにおける氷・氷および氷・他物質(ガラス,花崗岩)の摩擦測定を行った.氷・氷摩擦係数は,速度を10-4m/sから10-7m/sまで減少させるにつれて,0.1から1まで増加した.一方,氷・ガラス摩擦では速度10-3m/sから10-5m/sまで減少させるにつれて,0.04から0.02まで減少した.この速度領域における氷・氷摩擦係数が,低速度ほど増加する結果は,これまでの伝統的な凝着理論,すなわち摩擦面の氷の塑性流動だけでは説明できない.氷・花崗岩の摩擦係数は,速度を10-3m/sから10-6m/sまで減少させるにつれて,はじめ増加した後に減少した.氷 ...

In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Influence of velocity on ice-cone interaction
A series of upward breaking cone tests was conducted at NRC/IMD's ice tank in level ice using EG/AD/S correct density model ice. Cone angles of 45° and 60° were tested.

Warm ocean is eroding West Antarctic Ice Sheet [PDF]
Satellite radar measurements show that ice shelves in Pine Island Bay have thinned by up to 5.5 m yr^{-1} over the past decade. The pattern of shelf thinning mirrors that of their grounded tributaries-the Pine Island, Thwaites and Smith glaciers- and ...

Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

The quality of sea ice velocity estimates [PDF]
Several aspects of observed and estimated velocities for Arctic sea ice are explored. The long‐term mean ice motion field and associated variance are derived using 15 years (over 85,000 observations) of daily buoy motions. The mean field is separated into the part due to long‐term currents and internal ice stress and the part due to mean winds.

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Effect of velocity in icing scaling tests [PDF]
This paper presents additional results of a study first published in 1999 to determine the effect of scale velocity on scaled icing test results. Reference tests were made with a 53.3-cm-chord NACA 0012 airfoil model in the NASA Glenn Icing Research Tunnel at an airspeed of 67 m/s, an MVD of 40 microns, and an LWC of 0.6 g/cu m.
