Strings of Autumn is an international music festival which takes place every year between September and November in Prague, Czech Republic. The festival features a mix of jazz, classical music, experimental music, and world music. Its program is divided into three distinct categories, each with a particular musical focus: Inspiration, Crossover, and Luminaries. Strings of Autumn has been running since 1996.

Strings of Autumn was founded by Marek Vrabec in 1996 at the instigation of President Vaclav Havel, who hoped to start up a regular program of concerts at Prague Castle. These concerts often took place in parts of the castle previously inaccessible to the public. The first year featured mostly Czech artists, but in 1997 the festival showcased its first international artists, among them Jan Garbarek and the Hilliard Ensemble, who were making their first appearance in the Czech Republic. As the festival gained stature, it was able to attract an increasing number of high profile artists, including Michael Nyman, Magdalena Kozena and Oleg Maisenberg.

In 2004 a new president, Vaclav Klaus, was sworn in. The change of president led to a change in cultural policy at the castle, and the new administration announced it would no longer support Strings of Autumn. This was a major blow for the festival, which had by that point become a popular and established annual event. Klaus' decision received vigorous criticism, and a music magazine, Harmonie, nominated the castle administration for an 'anti-award,' suggesting that they had "decided to cancel one of the most interesting projects – in terms of artistic programming and performance – that exist in this country."

Strings of Autumn subsequently established partnerships with new venues in Prague, including the Rudolfinum, the Estates Theatre, the Municipal House, and Prague Crossroads. With the continued backing of the City of Prague and of private sponsors, the festival returned in 2005 with a program of ten concerts, including the return of Michael Nyman and the Czech debut of Gary Burton. In the years that followed, the festival continued to stage performances from international artists who had never played in the country before. Artists who have performed at Strings since 2005 include Brad Mehldau, Cassandra Wilson, Bobby McFerrin and Ute Lemper.

From January 1996 the Federal Government had outlawed the sponsorship of sporting events by tobacco companies. Thus Philip Morris could still sponsor a team but not directly market any of its products, resulting in the team being branded as Pack Leader Racing. After some teething problems with brakes in the opening rounds, the team began to move up the field with Jones leading during the early stages of the Bathurst 1000 before the car caught fire on lap 25.

Having lost the Philip Morris sponsorship, in 1997 the team ran #9 for Jones with sponsorship from Komatsu and Pirtek, and a customer car for Mark Larkham as #10 with Mitre 10 sponsorship. Both cars upgraded to Ford EL Falcon specifications. Larkham was involved in a high speed start line crash with former team driver Paul Romano at round 2 at Phillip Island which saw a new car completed for the next round. Jones won a heat at the final round at Oran Park.

Kirigalpotta
Kirigalpotta is the 2nd tallest mountain in Sri Lanka at above mean sea level, and is also the highest mountain in the country whose summit is accessible to the general public (the highest point, Pidurutalagala, is occupied by a military base and off-limits to the public). The peak is situated near the city of Nuwara Eliya, within the Nuwara Eliya District. Only one hiking trail provides access to the mountain's summit via the Horton Plains National Park, although the trail is not very popular.

https://en.wikipedia.org/wiki/Criticality%20index
Criticality index
Criticality index is mainly used in risk analysis. The Criticality Index of an activity (task) can be expressed as a ratio (between 0 and 1) but is more often expressed as a percentage. During a (e.g. Monte Carlo) simulation tasks can join or leave the critical path for any given iteration. The Criticality Index expresses how often a particular task was on the Critical Path during the analysis. Tasks with a high Criticality Index are more likely to cause delay to the project as they are more likely to be on the Critical Path.

Criticality index
If a task does not exist for some iterations (e.g. it is probabilistic) then it is marked as not being critical. For example, a task that existed for 50% of the iterations and was critical 50% of the time it existed would have a Criticality Index of 25%.

Index a project is less likely to be late. If a task has a 100% Criticality Index it means that during the analysis no matter how the task durations varied, the critical path always included the task. The task is therefore likely to be key in completing the project on time. Conversely tasks with a low or zero Criticality Index are much less likely to cause a delay in the project finish date.

https://en.wikipedia.org/wiki/Criticality%20index
Criticality index
Just because a task is on the Critical Path all of the time, does not always mean that the task is going to be significant to the project completion date. For example, a task that is only 1 day long is unlikely to affect the project finish but it can still have a 100% Criticality Index. To avoid this problem one must also measure the correlation between the duration of a task and the duration of the project. Spearman's Rank correlation or Pearson's Product Moment can be used to measure the correlation.

The larvae feed on Filipendula vulgaris, Rosa canina, Rosa pendulina, Rosa sempervirens, Sanguisorba minor and Sanguisorba officinalis. They mine the leaves of their host plant. The mine consists of a strongly contorted, intestine-like corridor with brown and coiled frass. The last part of the corridor often follows the leaf margin for some distance. At the end, the corridor widens into an elongate blotch. Pupation takes place outside of the mine.

Caripito
Caripito is a city in the state of Monagas, Venezuela. It has around 50,000 inhabitants. It is the third largest city in the state, after Maturín and Punta de Mata.

Caripito
Caripito is first recorded as a mission town, but the existence of this first settlement was short as it was destroyed by a major fire on 17 March 1783. Caripito has been known by a number of names, including La Palencia, San Juan, Caripe Horno, and finally Caripito, as a diminutive of the nearby Caripe. The town achieved political and territorial recognition when the Colón municipality was created in 1896. In 1910, the first school in Caripito was established. In 1924 the Standard Oil Company began oil exploration activities in the area and Caripito experienced a slight repopulation. When oil exploitation began in 1928 Caripito received an important boost to its urban development from the arrival of migrant labor, particularly from the Caribbean islands. In 1929, the Standard Oil Company began to build a storage yard and deep-water pier on the San Juan River and on October 15, 1930, the first tanker left the port with 20 thousand barrels of oil bound for Trinidad.

The establishment of the Harbor Master's Office, independent from that of Güiria, as well as the development of modern health services, hotels, power plants, transport links, military garrison, schools, an airport, and other civic amenities accelerated the development of the city, drawing migrant families from the states of Sucre and Nueva Esparta as well as the United States and the Caribbean. In 1931 the Standard Oil Company opened a local oil refinery with an initial capacity of 26 thousand barrels per day, the second of its kind after the San Lorenzo refinery built in the State of Zulia in 1917. In 1935 a Caripito terminal was opened on the San Juan River where Pan Am seaplanes could arrive from Central America and the Caribbean. In 1936 Caripito International Airport was selected by Amelia Earhart as the second stop on her trip around the world, spending the night at the Standard Oil Company facilities. The event was widely publicized in the world press and the company provided logistical support to continue the flight through South America.

In 1938, the Creole Petroleum Corporation increased the capacity of Caripito to 70 thousand barrels per day, making it the most important refinery in Venezuela until the expansion of the Amuay and Cardón refineries was completed in the mid-1950s. Caripito became the capital of the under a decree of January 19, 1940, signed by Governor José María Isava on January 30. Between 1941 and 1961 the population of Caripito doubled as a result of intense economic activity, but by the mid-1970s a third of the population had emigrated due to decline in oil production. In 1976, Creole's assets were nationalized and were managed by Lagoven, later by Corpoven and now by PDVSA in association with Repsol. After closing the refinery in 1976 and the oil terminal in 2002, attempts have been made to boost agricultural activity to take advantage of the fertile land.

The hardness of steel is usually stated as a number on the Rockwell C scale (HRC). The Rockwell scale is a hardness scale based on the resistance to indentation a material has. This differs from other scales such as the Mohs scale (scratch resistance testing), which is used in mineralogy. As hardness increases, the blade becomes more capable of taking and holding an edge, but is more difficult to sharpen and increasingly more brittle (commonly called less "tough"). Laminating harder steel between softer steel is an expensive process, though it gives the benefits of both "hard" and "soft" steels, to some extent (see Damascus steel).

6150, a chromium-vanadium alloy. Similar to 4140, 6150 is a tough steel with high impact resistance. It can be hardened to the mid-50s on the HRC scale. While a common material for swords or hatchets, it is less than ideal for most knives because of its limited attainable hardness. It tolerates less than ideal temperature control in forging and heat-treating (As does 5160). While it does not hold an edge as well as 1095, it is tough and easy to sharpen.

D2 is a high carbon, high chromium die steel and is the highest carbon alloy tool and die steel typically used in knife making. With a chrome content of 12.00%, some call it a "semi-stainless", because of the lack of free Chromium in solution, even though it is defined by ASM and ANSI as stainless which contains at least 11.5% by weight of chromium. It deserves the informal myth: "D2 knives hold an edge forever, and are impossible to sharpen." While not as tough as premium carbon steel, it is much tougher than premium stainless steel. D2 knife blades were popularized by Jimmy Lile, and later by Bob Dozier. ( AISI D2 / BOHLER K110 / ISO X153CrMoV12 / W. 1,2379 / GB-CINA Cr12MoV / JIS G4404 / SKD11 )

W2, tool steel that holds its edge quite well but is not very tough. Has a carbon content of 1.5. Most readily available W2 has a carbon content of no more than 1-1.1%. It can be left at high hardness levels (it can attain a quenched hardness of 67 Rc) and still be quite tough especially in larger knives with thicker spines as the core of the thick portion of the blade does not attain full hardness because of the shallow hardening nature of the steel. Bill Moran considered it to be almost as tough as 5160, but it was unavailable for a period of time. W2 is one of the carbon steels that can produce a nice Hamon in heat treating.

440C is also highly corrosion-resistant but is capable of having a very high hardness. The hardenability of 440C is due to it having the highest carbon content in the 440 group. Because of this, 440C is one of the most common stainless alloys used for knife making. The once ubiquitous American Buck Model 110 Folding Hunter was made of 440C before 1981. Böhler n695 is equivalent to 440C. Knife blades specified as being "440" can typically be assumed to be the lower-hardness 440A grade.

Due to extreme demand 10 years ago and Chinese counterfeits the steel has been excluded for Japanese market only and no longer can be exported from outside Japan. Chinese counterfeiting of steels where not even close of resembling the original steel and quality and therefore the decision was purely made for retaining the high quality of VG steels and makes the steel exclusively available for Japanese blacksmiths and manufacturers only making it nowadays a rare and exclusive high-end steel. Although old retailers outside Japan may have had a large quantity from the early days, it is officially no longer available outside Japan and only the finished products can be exported from Japan.
