Maturity paper

Analysis of healthy and mature paper samples dating back to the 17th century showed them to contain relatively large amounts of calcium and magnesium salts. Extract pH determinations confirmed the presence of alkalinity and the absence of acidity (2). (Extract pH is the solution pH of ground samples of the paper slurried in distilled water.)... [Pg.32]

The sterling-denominated Eurobond market has an active long-dated (30 years or more) sector, and this has led to two important differences in documentation compared to the Euro market. Firstly, to provide additional comfort to investors in long maturity paper, the bonds are often secured by charges on the issuers assets. It is worth noting in this connection that the common terminology can be inconsistent. Market... [Pg.193]

As the nonwoven fabrics industry has matured and technology has become pubHcly available, emphasis in the various sectors of the industry has changed. In the 1990s, some portions of the nonwovens industry are technology driven, whereas others are market driven. A number of firms are proprietary technology based, and others are turn-key plant operations. Some corporations are commodity roU-goods producers, and others are more oriented to niche market, high value-added products. Many nonwoven produces continue the quest for new markets and more opportunities to compete with textiles, paper, and plastics. [Pg.158]

The chief advantage of wood for containers is that many common species are free from harmful contaminants. For this reason wood had widespread use in the food and beverage industries, but it has now suffered severe competition from corrosion-resistant metals, plastics and paper products. Oak had a very extensive use in tight cooperage in the brewing industry, and its use for barrels still survives in the maturing of whisky and brandy and in the wine industries. Wood is particularly useful where acetic acid is present as this acid is corrosive to most common metals. [Pg.963]

This paper analyzes the development of the concept of alkahest from its origins in the Paracelsian corpus to its mature form in the works of Joan Baptista van Helmont (1579-1644) and his successors. Historians of science have usually focused on the chemical aspects of the alkahest, taking into account especially the claims that it was a substance capable of dissolving all kinds of matter. This paper shows the medical implications of the alkahest it was not only a "solvent," but an important means of revealing nature s... [Pg.396]

Lehner There is a paper by Goldstein (1981) in which he describes electron microscope (EM) studies of meiotic chromosomes. At meiosis I, chromosomes do not have two sister kinetochores. There is a maturation into two kinetochores between the two meiotic divisions. Have comparable EM analyses been done in yeast ... [Pg.135]

TFSA molecules have been extensively and successfully used as steam additives in cyclic steam operations(27-32). Recently, results of a TFSA-waterflood which was conducted in West Texas were reported(33). The purpose of the work described in this paper was to further evaluate the feasibility of recovering incremental oil in a mature waterflood by injection of surfactants which change the wettability of reservoir rock surfaces. In this paper, we present the results of laboratory studies with Thin Film Spreading Agents and the results of a carefully conducted TFSA-waterflood pilot in the Torrance Field located in the Los Angeles Basin of California. [Pg.578]

Koukounis, C., Wade, U.H., and Schechter, R.S. "Phase Partitioning of Anionic and Nonionic Surfactant Matures," SPE paper 8261, 1979 SPE Annual Fall Technical Conference and Exhibition of AIME, Las Vegas, September 23 26. [Pg.676]

Larval maturation studies, sometimes referred to as cultures, can be performed on fecal specimens applied to wet filter paper. Nematode larvae such as Strongyloides spp. or hookworm mature to the filariform stages in the culture container and migrate from feces into water, where they are detected microscopically. The procedure can be performed in a petri dish with a square of filter paper or in a large test tube with a strip of filter paper. [Pg.24]

Several papers have reported that, during germination, new LOXs are synthesized in the seedling and the cotyledons the LOX mRNAs synthesized during germination can also be found in the mature plant. Their levels were increased by the application of abscisic acid and jasmonic acid, or by stress such as wounding, pathogen infection, or water deficit (Porta and Rocha-Sosa 2002). [Pg.124]

This paper deals with the current status of this potentially very powerful tool and shows characteristics and capabilities, and some typical results. In the near future, while the CIS module will mature, it is foreseen that a so-called CIS user group will be initiated, which NATO countries can join. [Pg.70]

In the context of this paper, only the microdevices and the micropro-cess engineering for uses in tine chemistry and pharmacy are considered. The view will be process-based and deduced from a rough economic calculation of how mature the technology is and what needs to be done to promote it further. [Pg.209]

Some effects have been observed in fauna living close to paper mill discharges, such as skin and physiological diseases in fish and a decrease in the number of juveniles, changes in communities and population structure, changes in growth rates, and delayed sexual maturation and reproduction, among others [2,58,59]. [Pg.43]

It is not being suggested that these figures represent the total number of papers published on the subject since the database used does not contain publications from all publishers and it is highly unlikely that all relevant papers will have been indexed using this simple term. It does, however, reflect the significant increase in the number of papers on LC-MS published recently which, in turn, reflects the development of LC-MS into a routine and mature analytical technique. [Pg.129]

Another remarkable fact is that the number of published papers largely depends on the maturity of the technique and its frequency of use in the industry. For example, CE and HPLC are widely accepted techniques and take the majority of papers for their account, while CEC, a rather immature technique, and SFC, a less frequently applied one, are much less studied. Therefore, CE and HPLC can be recommended as the two techniques to be tested in a first instance, using either CD or polysaccharide CSP, respectively. [Pg.206]

D GIS provides a particularly useful method to address the challenges of deep mineral exploration as it permits spatial data analysis in a rigorous fashion (de Kemp 2007). Based on examples from the Noranda camp, one of Canada s most mature and economically important mining camps, the present paper highlights innovative approaches that can be... [Pg.27]

Such allelopathic activity is developed during maturation of oat plants. Whereas only little activity is found in roots, somewhat more is found in stem and leaves. The highest activity, however, is found in the caryopses during maturation, especially in the husks ( ). In the first part of this paper, we shall describe isolation and structural elucidation of the main inhibitor from the husks of Avena sativa, which can be considered as an allelochemical against seeds of several plants. The second part of the paper deals with allelochemicals from rose seeds which, although of different chemical structure, bear some relationship to the allelochemical from oats. [Pg.118]
