Seer (franchise). Seer () is a Chinese video game series and media franchise, including a cartoon series and film series. The franchise is owned by Shanghai Taomee Network in China.

Seer, which is an acronym for Space Energy Robot,  involves cartoon monsters (called 精灵) fighting one another, similar to the gameplay of Pokémon.

Characters
The game revolves Space Energy Robots that acquire monsters and go on missions. Most Seers are playable characters in the game. Some monsters include:

 Akexiya (阿克西亚) is an Ice-type elf capable of one-shotting enemies with its ultimate move.
 Moshidilu (魔狮迪露) is a Normal-type elf, first encountered by the player as a boss with a ridiculous amount of health.
 Puni (谱尼) is a Holy-type elf, one of the strongest of the game's early period (before 2012).
 Leiyi (雷伊) is an Electric-type Legendary elf introduced in Seer. As the second patron saint of Panor Galaxy and king of the new generations of electric-type elves, he created the Thunder Guard and leads the God of War alliance to protect the entire Seer System. Because of his fascinating appearance and a variety of powerful skills, he becomes one of the hottest monster in Seer series.
 Gaiya (盖亚) is a Fighting-type Legendary elf, one of the closest friends and comrades of Leiyi.
 Bokeer (波克尔) is a Flying-type elf, depicted as a wild, nimble, and beastly bird. It is capable of 2 very rarely encountered special moves - one that will always leave the enemy with at least 1 health remaining even if otherwise lethal, and 1 that always brings the enemy's health down to Bokeer's current health no matter what the enemy's original health was.
 Pipi (皮皮) is the primitive, unevolved form of Bokeer. It has large ears and has not yet developed wings. The large ears will eventually develop into wings when Pipi evolves. It is widely known as one of the cutest elves in the game.
 Hamoleite (哈莫雷特) is a Dragon-type elf, one of the hardest bosses to fight against in the early days of the game.
 Menghuwang (猛虎王) is a Ground-type elf, depicted as a fearsome, brutal tiger.

Flat sawing. Flat sawing, flitch sawing or plain sawing is a woodworking process that produces flat-cut or plain-cut boards of lumber.

Process
After an initial cut through the diameter of a log, parallel cuts produce flitches: strips of lumber with consistent thickness. Two cuts on each flitch trim the bark from the sides, and reduces it to a standard board width with squared edges. Two more cuts at each end set the length.

Lumber can be quickly flat-cut with a side-by-side set of mechanical saws. A slower but sturdier method involves passing the log back and forth over a single saw.

To reduce buckling that may occur along the middle of flat-cut boards, the initial cut may be offset from the diameter, and resulting sections cut further before cutting the flitches.

Comparison
Flat-sawn wood often exhibits "flat-" or "slash grain", where the angle between the visible growth rings and the width of the board is 45° or less. This makes the wood vulnerable to deformation as it dries, or if later exposed to moisture. Flat-sawn wood is less stable than quarter sawn or rift sawn wood, but can be produced more quickly and at lower cost.

The face of the board may show curved grain, sometimes with intricate patterns.

Heterometallic copper-aluminum superatom. The heterometallic copper-aluminum superatom is a Mackay‐type icosahedral cluster compound with formula [Cu43Al12](Cp*)12. It is an open‐shell 67‐electron superatom. It is notable for its large electron count compared to other heterometallic superatoms and its unprecedented electron structure of an open-shell configuration.  it was the largest heterometallic superatom to be created using wet chemical synthesis.

Synthesis
Combining (pentamethylcyclopentadienyl)aluminium(I) with  in benzene at 78 °C under an inert atmosphere for 48 hours, followed by slow cooling, forms black cocrystals of the compound with benzene:

The material is created from single-atom sources of copper and aluminium, which spontaneously separate from the organic compounds to form the superatom cluster. The exergonic nature of the reaction demonstrates that this specific arrangement of copper and aluminum atoms is stable.

Structure
According to crystallographic and computational analysis, the complex contains a central copper atom surrounded by a first icosahedral shell containing twelve copper atoms, followed by a second icosahedral shell containing twelve aluminium atoms (located at the vertices of the icosahedron) and thirty copper atoms (located at the midpoints of the edges). This central group of metal atoms (of radius 5.137 Å) is surrounded by twelve pentamethylcyclopentadienyl ligands (one attached to each aluminium atom) that assist in protecting it against further reaction. It was the first ligated heterometallic Mackay-type cluster to be discovered.

Tupolev Tu-74. The Tupolev Tu-74 was a proposed aircraft designed by the Tupolev Design Bureau in 1947.

History and specifications
The Tupolev Tu-74 family of planes is often described as the link between the piston and the jet age. The plan proposed producing 72 planes, but  instead lost out to a similar aircraft: the Ilyushin Il-28. According to the draft design, the aircraft would have had a wingspan of 22.36 m, an aircraft length of 16.35 meters, an aircraft height of 4.9 meters, a wing area of 60.2 square meters, a normal flight weight of 13.5 tons, a flight weight with overload of 15.1 tons, an empty aircraft mass of 10.14 tons, a maximum horizontal flight speed of 620 kilometers per hour at an altitude of 12,200 meters, climb time to 10,000 meters inn 21.4 minutes, a practical ceiling of 13,200 meters, and a flight range of 3,200 kilometers. It would have been fitted with either an M-93 engine or DB-84TK engine. The plane was armed with three NR-23 cannons, one for firing forward with an ammunition of 100 shells and two in two remote installations with an ammunition of 200 shells for the defense of the rear hemisphere. The Tupolev Tu-74 is also known as the Tu-73R as it is a variant highly similar to the Tu-73, a preceding design.

Mathis Vega 42. The Mathis Vega 42 was a 42-cylinder 6-bank in-line radial piston engine, designed and built in France, by Société Mathis Aviation in the late 1930s, with development continuing during and after WWII.

Design and development
Émile E. C. Mathis had begun designing and producing motor-cars from 1910. Société Mathis Aviation, formed in 1937, began designing aircraft engines, initially with the large and complex Vega.

The Vega (and the similar Vesta) had a 2-piece Aluminium-alloy crankcase, 7 Aluminium-alloy cylinder blocks, with one-piece Aluminium-alloy heads and steel cylinder liners. A 6-throw crankshaft ran in 7 plain bearings.

Development continued after the war, culminating in the   Vesta 42, which did not reach the hardware stage before Mathis closed its doors.

Operational history
The Vega engines were run on test-beds, and  some sources indicate the engine was flown 100 hours in a test bed aircraft during 1939, but no details of flight testing survive.

Variants
Vega 42AInitial version of the engine first run in 1938, rated  at 3,000 rpm. Two examples and a full-scale mock-up are reported to have been built.
Vega 42BAn improved variant, under development in 1940. Completed and unfinished engines were hidden from invading German forces, in the Pyrenees.
Vega 42D An enlarged capacity version which became the Vesta 42.
Vega 42E Post WWII development rated at  for take-off.
Vesta 42 An enlarged Vega, developed from 1942, with similar configuration, but  bore,  stroke and  displacement, rated at .

SPAD S.XV. The SPAD S.XV was a single-seat fighter designed and built in France and offered to fulfil a 1918 C1 specification (C1 - Chasseur single-seat).

Design and development
The 1918 C1 specification called for a medium altitude fighter with  payload and a  service ceiling, maximum speed of  and absolute ceiling of . The specification called for the use of several different engine types, one of which was the  Gnome Monosoupape 9Nc rotary engine. Five aircraft were allocated the Gnome in response to the specification: Morane-Saulnier MoS 27, Morane-Saulnier MoS 29, Courtois-Suffit Lescop CSL-1, Nieuport 28 and SPAD S.XV.

André Herbemont, at SPAD, designed a single-bay biplane with un-staggered, equal span wooden wings and a moulded plywood monocoque fuselage. The closely cowled Gnome engine was mounted in the nose, driving a 2-bladed propeller. Two  Vickers machine-guns were mounted in the forward upper decking, firing through the propeller disc, using synchronising gear.

First flown on 31 July 1917, the relatively low power of the Gnome engine limited any performance advantage over the SPAD S.XIII, so production was not authorised. The moulded plywood monocoque fuselage concept, however, was used extensively by Herbemont in subsequent designs due to its light weight and high strength.

Operational history
None of the S.XVs were accepted by the Aviation militaire.

Variants
S.XV/1First S.XV, armed with 2x Vickers machine-guns; one built.
S.XV/2Second S.XV, reportedly completed with a slightly longer span wings and a re-designed tail; one built.
S.XV/3Third S.XV, completed with reduced chord and wing area wings and a lengthened fuselage; one built.
S.XV/4Intended to be powered by a  Le Rhône 9R, but not completed.

Nicholas Trestrail. Nicholas Trestrail (December 1858  – 1922) was a British mining engineer in Redruth, Cornwall, England. He was the designer of the Harvey's Engine, a Cornish beam engine initially used as a pumping engine as of 1892 in the Carn Brea mine and from 1924 until 28 September 1954 in the East Pool mine.

He was born, worked, lived, and died in Redruth. He married Grace Wilkins Michell, had 6 children, and 1 servant.

The Cornish beam engine 

Trestrail built upon the high pressure steam engine technology of Richard Trevithick to design his large coal boiler driven single-acting high-pressure engine, implementing an equilibrium valve between the chambers above and below of the piston. Because of the dual-phase process the maximum of energy could be extracted from the steam. Efficiency was also increased by insulating the pipes, cylinders, and boilers. Also when the machine was not required to work at full capacity, cycles could be skipped, saving even more energy.  Due to its irregular mechanical movements caused by its design the Cornish engine was not useful for rotational duties like winching, but it was well adapted for water pumping using a linear moving lever. A sacrifice wooden block was used as an audible protective and alarm mechanism to notify the operator when too much steam would be applied at low power pumping conditions. In order to prevent machine breakdown, the operator would then immediately shut down or reduce the steam inflow.

Coal was not local to Cornwall; it was to be transported from South Wales by ship and train which required a lot of labor, so it was very expensive, and constituted a major part of the mining costs. Steam engine performance was expressed as duty, defined by Smeaton to be number of pounds of water raised one foot by one bushel of coal. Due to its design and functioning the engine was more fuel efficient than previous Watt engines in such a way that mine owners where required to pay a royalty based on the amount of fuel saving. The Harvey's Engine consumed typically 500 kg of coal per hour.

Longitudinal-section mode. Longitudinal-section modes are a set of a particular kind of electromagnetic transmission modes found in some types of transmission line.  They are a subset of hybrid electromagnetic modes (HEM modes).  HEM modes are those modes that have both an electric field and a magnetic field component longitudinally in the direction of travel of the propagating wave.  Longitudinal-section modes, additionally, have a component of either magnetic or electric field that is zero in one transverse direction.  In longitudinal-section electric (LSE) modes this field component is electric.  In longitudinal-section magnetic (LSM) modes the zero field component is magnetic.  Hybrid modes are to be compared to transverse modes which have, at most, only one component of either electric or magnetic field in the longitudinal direction.

Derivation and notation 
There is an analogy between the way transverse modes (TE and TM modes) are arrived at and the definition of longitudinal section modes (LSE and LSM modes).  When determining whether a structure can support a particular TE mode, one sets the electric field in the  direction (the longitudinal direction of the line) to zero and then solves Maxwell's equations for the boundary conditions set by the physical structure of the line.  One can just as easily set the electric field in the  direction to zero and ask what modes that gives rise to.  Such modes are designated LSE{x} modes.  Similarly there can be LSE{y} modes and, analogously for the magnetic field, LSM{x} and LSM{y} modes.  When dealing with longitudinal-section modes, the TE and TM modes are sometimes written as LSE{z} and LSM{z} respectively to produce a consistent set of notations and to reflect the analogous way in which they are defined.

Both LSE and LSM modes are a linear superposition of the corresponding TE and TM modes (that is, the modes with the same suffix numbers).  Thus, in general, the LSE and LSM modes have a longitudinal component of both electric and magnetic field.  Likewise the LSM modes are found by setting one of the transverse components of magnetic field to zero with analogous results.

Occurrence 
LSE and LSM modes can occur in some types of planar transmission line with non-homogeneous transmission media.  There are some structures that are unable to support a pure TE or TM mode and consequently the transmission mode must necessarily be hybrid.
