G.718 is an ITU-T recommendation embedded scalable speech and audio codec providing high quality narrowband (250 Hz to 3.5 kHz) speech over the lower bit rates and high quality wideband (50 Hz to 7 kHz) speech over the complete range of bit rates.
 In addition, G.718 is designed to be highly robust to frame erasures, thereby enhancing the speech quality when used in internet protocol (IP) transport applications on fixed, wireless and mobile networks.
 Despite its embedded nature, the codec also performs well with both narrowband and wideband generic audio signals.
Kerman carpets (sometimes "Kirman") are one of the traditional classifications of Persian carpets.
 They are named after Kerman, which is both a city and a province located in south central Iran, though, as with other such designations the term describes a type which may have been manufactured somewhere else.
 Kerman has been a major center for the production of high quality carpets since at least the 15th century.
 In the 18th century, some authors considered the carpets from the province of Kerman, especially at Siftan, to be the finest of all Persian carpets, partly because of the high quality of the wool from the region, known as Carmania wool.
Carrara marble is a type of white or blue-grey marble of high quality, popular for use in sculpture and building decor.
 It is quarried in the city of Carrara located in the province of Massa and Carrara in the Lunigiana, the northernmost tip of modern-day Tuscany, Italy.
Réva ("Wine"), or Dívka s hrozny ("Girl with grapes"), is an outdoor statue, installed in 1960 at Kampa Park in Prague, Czech Republic.
 The statue is a typical work of Karla Vobišová-Žáková, the first Czech professional female sculptor, aimed to figural and portrait sculptures.
 The almost life-size statue was created from Carrara marble, the piedestal from sandstone.
 The statue is separately registered and protected as a cultural monument since 1964.
 The last restoration was made in 1997.
Photoimageable thick-film technology is a combination of conventional thick film technology with elements of thin film technology, and it provides a low cost solution to producing high quality microwave circuits.
 The ability to directly photoimage the printed layers means that the technology can provide the high line and gap resolution required by high frequency planar components.
 It provides a feasible fabrication process to produce circuits operating at microwave and millimetre-wave frequencies.
 Circuits made using this technology meet the modern requirements for high density packaging, whilst yielding the high quality components required for very high frequency applications, including wireless communication, radar and measurement systems.
Morgex is a town and "comune" in the Aosta Valley region of north-western Italy.
 High quality white wine is produced here.
Potassium humate is the potassium salt of humic acid.
 It is manufactured commercially by alkaline extraction of brown coal (lignite)  Leonardite to be used mainly as a soil conditioner.
 The extraction is performed in water with the addition of potassium hydroxide (KOH), sequestering agents and hydrotropic surfactants.
 Heat is used to increase the solubility of humic acids and hence more potassium humate can be extracted.
 The resulting liquid is dried to produce the amorphous crystalline like product which can then be added as a granule to fertiliser.
 The potassium humate granules by way of chemical extraction lose their hydrophobic properties and are now soluble.
 Depending on the source material product quality varies.
 High quality oxidised lignite (brown coal), usually referred to as leonardite, is the best source material for extraction of large quantities of potassium humate.
 The less oxidised the coal the less potassium humate extracted.
 Sources low in ash produce the best quality.
 Less oxidised brown coal contains a higher proportion of the insoluble humin fraction and along with peat which is lower in humic acid content and usually high in ash content requires separation by filtration or centrifugation to remove ash, humin.
 Peat is also high in non humified organic matter that needs to be reduced to produce a high quality product.
 The benefit of peat is that it is usually 2-3 times higher in fulvic acid content, which are the low molecular weight fractions of humic acid that are high in oxygen containing functional groups and soluble at a low pH of <1.
 Fulvic acids have a higher cation exchange capacity and therefore have a higher chemical interaction with fertilisers and are able to form soluble chelates of trace metals.
Carrara ] (Emilian: "Carara" ) is an city and "comune" in Tuscany, central Italy, of the province of Massa and Carrara and notable for the white or blue-grey marble quarried there.
 It is on the Carrione River, some 100 km west-northwest of Florence.
Makrana marble is a type of white marble of high quality, popular for use in sculpture and building decor.
 It is mined in the town of Makrana in Rajasthan, India, and was used in the construction of several iconic monuments such as the Taj Mahal in Agra and the Victoria Memorial in Kolkata.
MazMaz - Founded in 1990 as the manufacturer of Natural Potato Chips start-up, Maz Maz was one of the first businesses to recognize the rapidly expanding capabilities of packed chips with high quality in Iran.
 From those early days, Maz Maz has grown into a leading manufacturer of high quality Chips, Nuts & Snacks.
 Its early mission focused on promotion of quality in production and packing of chips in Iran, Expansion and innovation of products in food industry and snacks, export to international market and to meet the customers’ needs and tastes.
 Today Maz Maz has reached to the point that its name guarantees a healthy product for the consumers.
 It started only with one taste and today it provides more than 15 tastes in Chips product as well as snacks, and dried nuts in Iran and even at International level.
 The Kishchips (1990) and Felix (2011) are companies that sell their products by this brand.
