Settling velocities of small ice crystals [PDF]
Settling velocities, masses and external dimensions were determined experimentally for small freely falling ice crystals grown for about 100 s at 12 different temperatures within the range −3.4 to −20°C. The corresponding terminal velocities were calculated using the above measurements, together with the empirical Be-Re relationships, deduced from ...

TerraSAR-X Capabilities in Polar Regions [PDF]
DLR participates in a coordinated plan established by the space agencies for the optimum use of SAR acquisitions over the Artic and Antarctica for the remaining period of IPY and beyond. Due to the specific advantages of the X-band in respect to snow and

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Local scour around a bridge pier under ice-jammed flow condition – an experimental study
The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and local scour processes.

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. The effect of ice draft velocity in the range 0.005 to 0.5 m/s was studied for ice thicknesses ranging from 35 to 110 mm. The mean peak forces in both horizontal and vertical directions

We investigate the accuracy and robustness of one of the most common methods used in glaciology for the discretization of the $\mathfrak{p}$-Stokes equations: equal order finite elements with Galerkin Least-Squares (GLS) stabilization.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Regional changes in the flow velocity of Antarctic glaciers can affect the ice sheet mass balance and formation of surface crevasses. The velocity anomaly of a glacier can be detected using the Double-Differential Interferometric Synthetic Aperture Radar

Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
