First-grade

Most off-quahty or scrap polypropylene fibers may be repeUetized and blended in small percentages with virgin polymer to produce first-grade spunbonded fabrics. The economics are of great importance in a process where high yields are required in order to be competitive. Some manufacturing equipment direcdy recycles edge-trim back into the extmder where it is blended back into the polymer melt (see Fibers, olefin). [Pg.163]

The use of the modelling-based strategy above described was investigated from an action research perspective by one of us (PF) who was the chemistiy teacher of a first grade medium level school class of 26 students (14-15 years old) in Brazil. [Pg.294]

Other investigators have also found that parameters of neurobehavioral function are associated with tooth lead levels. A cross-sectional cohort of school children in first grade was ascertained in the city of Aarhus, Denmark (Hansen et al. 1989), where the population is very homogeneous with regard to ethnicity and language. A total of 2,412 children were contacted and asked to contribute a shed deciduous tooth. A total of 1,291 children responded (response rate = 54%). Lead was determined in the... [Pg.95]

And even before their ultimate ascension, his true disciples had the capacity to rid themselves of the taint of original sin and reach toward spiritual perfection and eternal life. But to attain such moral purity, they must be prepared to overcome terrible ordeals that would be strewn in their path. Only seventy-two Masons could achieve the first grade, forty-eight the second, and so on up to the final grade, where a dozen immortals would eventually reign forever as spiritual rulers of the world. Masons must realize, however, that the devils necromancers were constantly at work to divert them from this true path with temptations—earthly greed and cupidity. As a rule of thumb, they should trust spirits whose names ended in er, and shun those whose names ended in el. ... [Pg.79]

Evaluating an Adult. Evalnating an adnlt for ADHD carries its own dilemmas and is no less difficnlt. Althongh the diagnostic criteria remain the same, ADHD in an adnlt does look somewhat different from the way it does in a 6-year-old child. In addition, one mnst also determine that the illness was present before age 7. Withont parents and elementary school teachers there to help, it can certainly tax the memory of an adnlt patient when asking about any problems experienced in the first grade. However, the task is not impossible. [Pg.237]

Raw rubber can be either natural or synthetic. The standard grades of natural rubber are smoked sheets and pale crepe. For high grade products, first grade smoked sheets, namely RMAIX or Pale Crepe, is used. Pale Crepe is practically colourless and is preferred in products where delicate colour, extreme whiteness or transparency... [Pg.15]

The acidity should not, as a rule, exceed o-i% as lactic acid or 0-054% as sulphuric acid, in products of the first grade, it may be as high as 0-3% as lactic acid or o- 6% as sulphuric acid in second grade materials... [Pg.77]

Evidence Ms. S., my first-grade teacher—she paid attention to each child s individual needs, while also keeping us engaged in academic matters. [Pg.52]

A 6-year-old African American boy presented with a 6-month history of nausea, abdominal discomfort, and diarrhea with three to four watery stools a day associated with passage of much gas. These complaints began soon after he started first grade when he was required to drink 2 cups of milk with his school lunch. The symptoms occurred after lunch, and he felt much better after having a bowel movement. No blood was noted in the stool. He was mostly symptom free on weekends, when he rarely drinks milk. There has been no fever or no weight loss, and his appetite has remained good. [Pg.266]

Sharon L. Neal, University of Delaware I am glad I came to this workshop, but when I first heard about it, my first reaction was, Oh, no, not another one of these things. My reason for feeling that way was that I was the only black child in my first-grade class. I have been hearing people talk about how to fix this problem for 35 years. [Pg.145]

Application E PTA (Eastman polymer-grade terephthalic acid) is an excellent raw material for engineering plastics and packaging materials, bottles, other food containers including hot fill, as well as films. The process is proven to be suitable for the production of all kinds of polyester fibers and containers without limitation, at international first-grade quality. [Pg.193]

The first grade of the fire lasts until the white appears, and takes place with one lamp in three months. The next takes place until the white breaks up, with two wicks in the space of three months. The third until the white is fixed the fourth until the end of three months. [Pg.161]

MATURATIO — is the Elevation from a Coarse and Rough Condition to Maturity and Perfection. There are four kinds of Maturation, each of which is accomplished by a moderate heat of the first grade, or near it, it mud, in a bath, in scum of olive oil, in fine cut straw, in a dry stone, with damp hay, with grape stones, by sunshine, the moon, etc. The four kinds are called—Digestion, Circulation, Fermentation, and Projection. [Pg.210]

It is important that the first grade from Supplier 1 has the same nominal degree of polymerisation as the first grade from Supplier 2, and as the first grade from Supplier 3, etc. Thus, the first grades for all the suppliers have a certain common property which distinguishes them in some way from the second grades of all the suppliers, etc. [Pg.79]

The HAp/Col composites were synthesized and the precipitates obtained were aged at 40°C for 3 h and cross-linked with GA (first grade, Wako Pure Chemicals... [Pg.438]

As of this writing, 3-, 5- and 7-qubit NMR quantum computers have been realized. The latter is capable of carrying out Shor s algorithm to factor the number 15, thus equalling the computational ability of a first-grade elementary school student. [Pg.149]

Derivation From the seeds of the castor bean, Ricinus communis (Brazil, India, the former U.S.S.R., U.S.). They are cold-pressed for the first grade of medicinal oil and hot pressed for the common qualities, approximately 40% of the oil content of the bean being obtained. Residual oil in the cake is obtained by solvent extraction. Chief constituent Ricinolein (glyceride of ricinoleic acid). [Pg.243]
