Balliranoite. Balliranoite ((Na,K)6Ca2(Si6Al6O24)Cl2(CO)3) is a mineral that was discovered at Monte Somma – Vesuvio volcanic complex, Campania, Italy. This mineral is named in honor of Paolo Ballirano (b. 1964), Italian crystallographer and professor in the Department of Earth Sciences, University of Rome ‘‘La Sapienza’’, who has made important contributions to the crystal chemistry of cancrinite-group minerals.

Occurrence
Balliranoite is found in an alkaline skarnlike rock composed of orthoclase, phlogopite, clinohumite, calcite, diopside, pargasite, haüyne, apatite and  balliranoite, as product of the metasomatic interactions between alkaline magma and limestone. These chemical alterations by hydrothermal and other fluids replace elements in the chemical structure, changing the mineral composition of the rock.

Mineral properties
The idealized formula for balliranoite is (Na,K)6Ca2(Si6Al6O24)Cl2(CO3), and the empirical formula based on 12 Si atoms with isomorphic substitution by Al atoms is: Na4.70Ca2.53K0.73(Si6.02Al5.98O23.995)Cl2.34(CO3)0.82(SO40.27*0.12H2O. This is a uniaxial (+) mineral with w = 1.523(2), e = 1.525(2), composed of the following compounds:

Fianelite. Fianelite is a mineral belonging to the manganese vanadate category, found in iron-manganese ores. Named after the place where it was found, Fianel, a mine located in Val Ferrera (Ferrera valley), in the canton of Graubünden, Swiss. This mineral is found in small amounts in metamorphosed iron-manganese ores. This is the last crystallization of vanadate at the site since medaite was the last vanadate mineral being crystallized, but because of retrograde metamorphism, occurring at the place, vanadium moved into medaite veinlets, forming cross-cutting fianelite on medaite.

Occurrence
This mineral is found in the Suretta nappe which is composed of three main units going from a quartzite base to dolomitic and calcitic marble, to a calcschist top. Fianelite is only found at the Triassic dolomitic and calcitic marbles unit which contains metamorphosed iron and manganese ores. Fianelite is found as small fractures of less than 1 mm in size in association with quartz, aegirine, and iron hydroxide-oxides like limonite. These fractures are found cross-cutting veinlets, which are made out of quartz, rhodonite, kutnohorite, aegirine, parsettensite, and different vanadium minerals, that are at the same time cross-cutting lenses of medaite-rich rocks which are found in the iron and manganese ores.

Physical properties

Fianelite's crystals grow in polycrystalline crusts and rosettes that can measure up to 2.5 mm in diameter, and when strangely found as single crystals, they can measure up to 0.2 mm in diameter. It presents good parallel cleavage on {001} and {100}.  The single crystals resent a platy habit and striations parallel to the a-axis. VHN values were measured and used to determine a Mohs hardness of approximately 3.

Optical properties
Fianelite is an orange-red mineral with a vitreous luster and orange streak. Its crystals are transparent with striations parallel to the a-axis. The crystals are biaxial, so they have two optic axes meaning that they will split light rays into two. The angle between the two optic axes is less than 10°. It shows a strong pleochroism on (010) displaying different colors from yellow to red.

Chemical properties
The empirical formula for fianelite is Mn1.98(V1.57As0.44Si0.01)O7·2H2O. Manganese dioxide (MnO6) and manganese trioxide (MnO2O6) are found in chains of octahedrons that are connected by two tetrahedrons of orthovanadate (VO4), from which one of them bonds with arsenic.

Chemical composition

X-ray crystallography
Fianelite belongs to the monoclinic crystal system with a space group of P21/n. The unit cell dimensions are a = 7.809(2) b = 14.554(4) c = 6.705(4)
β = 93.27(3)◦ Z=4

IBM Eagle. IBM Eagle is a 127-qubit quantum processor. IBM claims that it can not be simulated by any classical computer. It is two times bigger than China's Jiuzhang 2. It was revealed on November 16, 2021 and was claimed to be the most powerful quantum processor ever made until November 2022, when the IBM Osprey overtook it with 433 qubits. It is almost twice as powerful as their last processor, the 'Hummingbird', which had 65 quantum bits and was created in 2020. IBM believes that the processes used in creating the 'Eagle', will be the backbone for their future processors.

Elgoresyite. Elgoresyite, first discovered during the crystallographic study of the Suizhou meteorite, is a naturally occurring, high-pressure iron-magnesium silicate mineral. High-pressure poly morphs of magnesium silicates have been rarely discovered on Earth, due to retrograding as they ascend to the surface. It is named after Ahmed El Goresy.

Occurrence 
Currently, Elgoresyite has only been known to occur in the shock-induced melt veins of the Suizhou meteorite. These veins are ~300 μm in thickness. It is found in association with the minerals ringwoodite, olivine, tetragonal ringwoodite, taenite, and MgSiO3 rich glass.

Appearance and properties 
Physical properties such as color, luster, streak, hardness, tenacity, cleavage, fracture, and density could not be determined due to small grain size of the only known sample available. Optical properties as well were not able to be determined for this same reason. Density (calc) however is 4.315 g/cm3. This was based on the empirical formula and single-crystal XRD data.

Chemical properties 
The empirical formula is (Mg3.38Si1.95Fe2+1.60Al0.05Na0.03Ca0.02)Σ = 7.03O9. The simplified and ideal chemical formula is (Mg,Fe,Si)7O9.

Crystallography 
The crystal system is monoclinic, and the space group is C2/m (#12). The unit cell parameters are :a = 9.397(2) Å, b = 2.763(1) Å, c = 11.088(3) Å, β = 94.25(2)°, volume V =287.10(14) Å3, and number of formulas per unit cell, Z = 2.

RK 20. The RK 20 is an American trailerable sailboat that was designed by Lyle C. Hess as a cruiser and first built in 1972.

The RK 20 is a development of the Hess-designed Balboa 20, as is the Ensenada 20.

Production
The design was built by RK Industries, a subsidiary of Coastal Recreation, in the United States. It was built between 1972 and 1981, but it is now out of production.

Design
The RK 20 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig; a spooned, raked stem; an angled transom; a transom-hung rudder controlled by a tiller and a swing keel or fixed fin keel. The swing keel version displaces  and carries  of ballast, while the fin keel version displaces  and carries  of ballast.

Two cabin designs were available, a trunk cabin and a raised deck version.

The fin keel-equipped version of the boat has a draft of , while the swing keel-equipped version has a draft of  with the keel extended and  with it retracted, allowing operation in shallow water, or ground transportation on a trailer.

The boat is normally fitted with a small  outboard motor for docking and maneuvering.

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee berths in the main cabin. Cabin headroom is . The fresh water tank has a capacity of .

The design has a PHRF racing average handicap of 264 and a hull speed of .

Operational history
In a 2010 review Steve Henkel noted, "the RK20 fixed-keel version would seem preferable, since it eliminates the mechanical problems some owners have experienced with the swing keel."

ETUT. ETUT (European Training network in collaboration with Ukraine for electrical Transport) is a research project funded by the European Commission's Horizon 2020 program under the Marie Sktodowska-Curie Actions Innovative Training Networks (MSCA- ITN) scheme. The project, undertaken by a collaborative effort of the University of Twente, the University of Nottingham, and Dnipro National University of Railway Transport, aims to develop efficient interfacing technology for more-electric transport amidst the ever-increasing demand in transportation systems which contribute to increased carbon dioxide emissions. The project has employed 12 Early Stage Researches (doctoral candidates) who will work closely with six industrial partners to improve upon the existing electrical and energy storage systems that will help in alleviating the reliance on non-renewable energy sources for large-scale transportation systems such as railways and maritime transport. The project is segregated into two main groups with one focusing on power electronics for efficient use of energy resources in power delivery, and the other on electromagnetic compatibility of such systems.

History 
With the increasing use of solid-state devices in transportation systems, a number of electromagnetic interference and interoperability problems are occurring which could hinder the electrification of transport on a global scale. This requires a closer inspection of the interaction of power electronic converters with equipment of the information and communications technology. With this in mind, MSCA ETUT brought together researchers from different academic backgrounds spanning all over the globe to contrive innovative ways of countering these problems. Jan Abraham Ferreira (IEEE Fellow, former President of IEEE Power Electronics Society ), Frank Leferink (IEEE Fellow and Director EMC at Thales Nederland), Patrick Wheeler (IEEE Fellow and Global Director of the University of Nottingham's Institute of Aerospace Technology ), Gert Rietveld (IEEE Senior Member, Chief Metrologist at Van Swinden Laboratorium),  Dave Thomas (IEEE Senior Member and Head of the George Green Institute for Electromagnetics Research ), Thiago Batista Soeiro (IEEE Senior Member) are some of the prominent members of this programme. The project officially started on March 1, 2021, and is set to culminate on February 28, 2025. Shortly after the commencement, J.A. Ferreira, a pioneering member of the project passed away.
