NanoDragon. NanoDragon is a 3U CubeSat built by the Vietnam National Satellite Center (VNSC). NanoDragon will use its automatic identification system (AIS) receiver to monitor vessels, and will also test the accuracy of its attitude control using an optical imager. It carries an advanced OBC (on board computer) developed by Japan's Meisei Electric.

Although NanoDragon was successfully launched, the ground stations unable to contact with the satellite.

Rockbridgeite. Rockbridgeite is an anhydrous phosphate mineral in the "Rockbridgeite" supergroup with the chemical formula Fe2+Fe3+4(PO4)3(OH)5.  
It was discovered at the since-shut-down Midvale Mine in Rockbridge County, Virginia, United States.  The researcher who first identified it, Clifford Frondel, named it in 1949 for its region of discovery, Rockbridge County.

Structure 
The stable form of rockbridgeite is orthorhombic 2/m2/m2/m, space group Bbmm. Face-sharing trimers in the structure share octahedron corners, forming chains of octahedra extending in the direction of the b-axis. Adjacent chains formed from two trimers and (PO4) groups extending along the direction of the a-axis, resulting in sheets parallel to (001). Each chain of octahedra is connected by a layer of tetrahedra extending along the direction of the a-axis.

Unit cell 
The unit cell parameters are a = 14 Å, b = 17 Å, and c = 5.2 Å, with 4 formula units per unit cell (Z = 4).
More accurate values are given by various sources as follows.

a = 13.783 Å, b = 16.805 Å, c = 5.172 Å, β = 100.313(1)°

Optical properties 
Rockbridgeite varies from green, to black, to brownish green, to reddish brown. It is subtranslucent, with a greenish gray streak and vitreous to dull luster.  The refractive indices are Nx = 1.875, Ny = 1.880, Nz = 1.897.

Physical properties 
Rockbridgeite shows perfect cleavage on {100}, distinct cleavage on {010}, and distinct cleavage on {001}. Rockbridgeite is a brittle mineral, with an uneven fracture, hardness 4.5 and specific gravity 3.40.  It is soluble in hydrochloric acid HCl, but not in nitric acid HNO3 or sulfuric acid H2SO4.

Environment 
Rockbridgeite primarily forms in igneous rocks when the primary iron and manganese phosphates in granite pegmatites undergo mineral alteration through redox reactions, resulting in these phosphates becoming oxidized and causing rockbridgeite to form. More rarely, rockbridgeite can also form in sedimentary rocks in association with limonite from iron ore deposits. Associated minerals include triphylite, hureaulite, barbosalite, roscherite, and limonite.

Localities 
The type locality is the since-shut-down Midvale Mine in Rockbridge County, Virginia, United States.  Other localities for rockbridgeite include sites in Brazil, Portugal, Bavaria, Saxony, South Australia, Namibia, Zimbabwe, and Morocco.
Type material is conserved for reference in Harvard University in Cambridge, Massachusetts, United States.

Scaled particle theory. The Scaled Particle Theory (SPT) is an equilibrium theory of hard-sphere fluids which gives an approximate expression for the equation of state of hard-sphere mixtures and for their thermodynamic properties such as the surface tension.

One-component case 

Consider the one-component homogeneous hard-sphere fluid with molecule radius . To obtain its equation of state in the form  (where  is the pressure,  is the density of the fluid and  is the temperature) one can find the expression for the chemical potential  and then use the Gibbs–Duhem equation to express  as a function of .

The chemical potential of the fluid can be written as a sum of an ideal-gas contribution and an excess part: . The excess chemical potential is equivalent to the reversible work of inserting an additional molecule into the fluid. Note that inserting a spherical particle of radius  is equivalent to creating a cavity of radius  in the hard-sphere fluid. The SPT theory gives an approximate expression for this work . In case of inserting a molecule  it is

,

where  is the packing fraction,  is the Boltzmann constant.

This leads to the equation of state

which is equivalent to the compressibility equation of state of the Percus-Yevick theory.

Mercedes-Benz M15 engine. The Mercedes-Benz M15 engine is a naturally-aspirated, 1.7-liter, straight-6, internal combustion piston engine, designed, developed and produced by Mercedes-Benz; between 1931 and 1936.

M15 Engine
The car was powered by a six-cylinder 1,692 cc engine: maximum power was set at  at 3,200 rpm.   The engine featured central lubrication and the water-based cooling system for the engine employed both a pump and a thermostat.  Power was transmitted to the rear wheels via what was in effect a four-speed manual transmission, on which the top gear operated as a form of overdrive. Third gear used the 1:1 ratio conventionally used by a top gear, and there was a fourth gear with a ratio of 1 : 0.73. Fuel economy was quoted as  and top speed 90 km/h (56 mph), which combined to represent a competitive level of performance in the passenger car market of that time.
