Investing in titanium has bome a viable alternative investment strategy.

Titanium is a dark grey, light metal that is widely used in the industrial world. Titanium and its alloys are used in aerospace, shipbuilding, steelmaking, chemical, armor plating, laptops, heat exchanges, golf clubs, and even body piercings and football helmets. Its wide application makes the metal a necessity for a number of industries and companies alike, making it a prime investment for those looking to make a play on larger macroeconomic trends. Only 5 percent of all mined and synthetic titanium minerals are actually used to make titanium metal, with the remaining 95 percent used to manufacture titanium dioxide (TiO2).

Palazzo Giustinian Recanati is a palace in Venice, Italy, located in the Dorsoduro district and overlooking the Giudecca Canal, just to the left of Palazzo Clary.

History
Palazzo Giustinian was built in the 16th century for one branch of the Giustinian family, that was linked to the Morosini family by marriage. Then the palazzo passed to the Recanati, a family originally from Badia Polesine and in the 17th century ascribed to the Venetian patriciate. Currently, the building is well-preserved in all its parts and still belongs to the descendants of the Giustinian Recanati family.

Architecture
The palazzo is of three floors. The façade has, on the ground floor, a large portal decorated by the Giustinian stone coat of arms. The noble floor is decorated by a quadrifora flanked pairs of monoforas. All openings on the noble floor are supported with stone balconies and inscribed in rectangular frames. The attic level, terminating with a denticulated cornice, offers a series of eight square windows.

The rear façade of the palace has neoclassical lines, due to an 18th-century intervention, probably by Antonio Diedo. This facade overlooks a small garden on the Ognissanti river, from which it is separated by a wall, on which stands a nineteenth-century statue representing the Madonna and Child.

Internally, the palace is sumptuously decorated with eighteenth-century stuccos and antique furnishings.

Background
With their new and independent label Debut, Mingus and Roach recorded a number of records as producers in 1953, including the debut albums by Kenny Dorham, Paul Bley, Sam Most, John LaPorta and Teo Macero. Mingus himself was not involved in all these recordings as a bass player. [4] Like his idol Duke Ellington, Mingus relentlessly experimented with his compositions by constantly looking for new instrumental combinations, voicings, timbres and suitable rhythmic elements. [5]

Under his own name, Charles Mingus recorded six titles in October 1953, four of which were published; his band included trombonist Willie Dennis, trumpeter Ernie Royal, woodwinds Joe Maini, Teo Macero and Eddie Caine, cellist Jackson Wiley, pianist John Lewis and drummer Kenny Clarke; on the two titles "Eclipse" and "Blue Tide" the singer Janet Thurlow can be heard, the wife of Jimmy Cleveland. [6] In addition to Mingus and Spaulding Givens as arrangers of the session, the young pianist Paul Bley acted as musical director (conductor).

Gunther Schuller wrote on “Eclipse”, “Mingus’ approach is counterpoint or polyphonic, in that the cello acts as a second voice to the solo vocal part, thus achieving vertical harmonic connections as a result of linear developments. This is also one of the many examples of jazz returning to the early polyphonic concepts of New Orleans, almost forgotten in Swingara with the advent of arrangers and the constant use of 'block chordally' homophonic arrangements. This is in connection with the various attempts to return to a format of chamber music in [then] jazz, more in an orchestral sense, in which individual instrumental parts work with a greater degree of linear / melodic independence. "[8] [9]

Limit
The static limit (or static surface) is a hypersurface around a rotating black hole, which is the outer boundary of the region, inside which any body (or photon) can no longer be at rest relative to a distant observer. To stay clear from falling on the surface of the event horizon, a body under the static surface must rotate with a positive angular velocity around the black hole and along with it. For a non-rotating hole, the event horizon and the static limit coincide, and for an unperturbed rotating hole, they touch each other only at the poles and look like ellipsoids of revolution in the Boyer-Lindquist coordinates. The space between them is called the ergosphere. For a Kerr black hole, the static limit is given by {\ displaystyle r = M + {\ sqrt {M ^ {2} -a ^ {2} cos ^ {2} \ theta}}} {\ displaystyle r = M + {\ sqrt {M ^ {2} -a ^ {2} cos ^ {2} \ theta}}}. The appearance of the ergosphere is an example of an extreme manifestation of the effect of dragging inertial frames of reference by rotating bodies.

Physical sense
Physically, the presence of a static limit means that it is possible to remain at rest, having reached the static limit, only having the speed of light. Bodies with a lower speed are drawn into spiral motion with a gradual approach to the event horizon, from where there is no return in principle. Unlike a body that is beyond the event horizon, it is still possible to escape from under the surface of the static limit - at a certain angle and speed of entry into the ergosphere, part of the mass can be dropped into a black hole, but the remaining mass, having received a powerful acceleration, will be thrown out beyond the static limit.

You can see the deep similarities between a rotating black hole and the famous vortex effect - for example, a giant whirlpool. The gravitational field of the Kerr-Newman black hole resembles a cosmic whirlpool. A spaceship passing by is sucked into the center like a normal boat. While the ship is outside the limit of static, it can still move "wherever it wants". In the region (shown in gray) between the static limit and the event horizon, it is already forced to rotate in the same direction as the black hole; its ability to move freely decreases with further suction, but it can still get out, moving along an unwinding spiral. The interior of the horizon is shown in red: it is no longer possible to escape from there, even moving at the speed of light. The situation is beautifully illustrated in the story of Edgar Poe "The Overthrow of Malstrom" (1840).

Interesting Facts
Theoretically, the "most ecological way of obtaining energy", called the Penrose process, is possible - a "garbage truck" approaching a black hole dumps debris into it and moves away from the vicinity of the black hole, having more energy than before this maneuver. Thus, it is possible to convert up to half of the rest mass of the discarded garbage into kinetic energy, which makes the process very tempting, but still difficult to implement.

Gold-collar worker is a member of a recently emerged social class of highly qualified workers.

scientists and specialists with entrepreneurial traits in the use of their professional knowledge.

These are programmers of controlled industrial computing complexes, operators of robotic industries, specialists in biotechnology and supernova materials.

highly qualified scientists and specialists who successfully apply their knowledge in the field of entrepreneurship for the purpose of personal enrichment.

Emergence
Blue-collar workers emerged in the United States during the Industrial Age as work migrated from farms to factories. White-collar office workers became a significant class in the twentieth century, outnumbering their blue-collar brethren by midcentury. But the white or blue paradigm has clearly out-lived its utility. Corporations increasingly require a new layer of knowledge worker: a highly skilled multidisciplinarian who combines the mind of the white-collar worker with the hands of the blue-collar employee.

Examples
Surgeons, engineers, anesthesiologists, lawyers, and airline pilots

Gold-Collar Worker– was first used by Professor Robert Earl Kelley of Carnegie Mellon University in his 1985 book The Gold-Collar Worker; It is a newly formed phrase which has been used to describe either young, low-wage workers who invest inconspicuous luxury (often with parental support). It is also used to refer to highly-skilled knowledge people who are highly valuable to the company. Example: Lawyers, doctors, research scientists, etc.

This a new breed of highly skilled multidisciplinary employee is clearly what drives intellectual capital companies, they bring the innovation, change the game, build companies to the IPO stage, and are the life-blood of the American economy. “Gold” referred to the hefty salaries and profits that their minds and skills garnered. Gold collar workers need to constantly update their skills to stay current with emerging technology; this is a core value to them. Learning must be a continuous process, one that is afforded by companies on the job or through extracurricular opportunities.
