Very deficiency

Butadiene—Methacrylic Acid Ionomers. Carboxyl groups can readily be introduced into butadiene elastomers by copolymerization, and the effects of partial neutralization have been reported (63—66). The ionized polymers exhibit some degree of fluidity at elevated temperatures, but are not thermoplastic elastomers, and are very deficient in key elastomer properties such as compression set resistance. 

In 1921 came confirmation of a sort in validating Osborne and Mendel s claim that 10-16 cc of milk were needed per day by the rat. Dutcher reported that 10 cc of milk obtained from cows on vitamine-rich rations usually sufficed in furnishing sufficient A and B for normal growth, while larger quantities of milk produced on vitamine-poor rations were very deficient in both food accessories. However, water-soluble B did not fluctuate to any great extent since most dairy animals received some grain. (53)... 

Feed has relatively little effect on the concentration of most elements in milk because the skeleton acts as a reservoir of minerals. The level of citrate in milk decreases on diets very deficient in roughage and results in the Utrecht phenomenon , i.e. milk of very low heat stability. Relatively small changes in the concentrations of milk salts, especially of Ca, Pj and citrate, can have very significant effects on the processing characteristics of milk and hence these can be altered by the level and type of feed, but definitive studies on this are lacking. 

In discussions to this point, no significant interaction between a guest and its medium has been considered. This is probably the case in the reaction cavity model of Cohen [13] as well, since product selectivity was attributed mainly to the presence or absence of free volume within the cavity. The analogy of guests in hosts to balls in boxes is very deficient, but is really not different from the situation in the kinds of crystal systems which first inspired the Cohen nomenclature. Interatomic attraction and repulsion was important in analyzing those systems and was even critical to the crystal engineering used to assemble some of the systems used in the studies by Schmidt and his co-workers [1,48,89]. In addition to being stiff or flexible, cavity walls must... 

The chemical actions which occur in the fixation of nitrogen under these conditions have been studied by L. Hiltner, but the results are indefinite. Many soils are very deficient in the bacterium radicicola, and experiments have been made by numerous workers—A. P. Aitken, C. Barthel, G. Bredmann, H. R. Christensen,... 

Maize gluten meal is not a very suitable feed for poultry since it is of relatively low palatability and being very deficient in lysine has an imbalanced AA profile. However, it can be incorporated in broiler and layer diets as a source of natural yellow pigment since it is rich in xanthophyll pigments (up to 300mg/kg). Maize gluten meal may no longer be available or economic for feed use as it is used extensively as a natural weed-killer in horticulture. 

Finally, it must be noted that the evolution of tolerance is a necessary condition for the evolution of a population able to colonize a mine, but it may not be sufficient. Mines differ from normal habitats in many ways apart from mere metal contamination the soil structure is usually worse, and the organic content less, so that the soils dry out quickly the soils are frequently very deficient in nitrogen and phosphorus and other essential elements and wind and water erosion may mean that seedling establishment is very difficult (Baker and Proctor, 1990). The result is that plants have to be able to adapt to all these conditions as well as to the metal contamination in practice, only those species which show at least some preadaptation to these harsh conditions are going to be able to evolve tolerant races. It may well be that it is this factor, rather than the evolution of tolerance per se, that is most important in determining which species are able to evolve tolerant races. Such arguments may be relevant when comparing the evolution of tolerance in mine environments and aerially-contaminated sites such as those around smelters, where soil conditions and selective forces are markedly different (Baker, 1987). 

Among the oxides and sulphides, only CdO adopts the octahedral rock salt structure found with group 2 element, although the solid is normally very deficient in oxygen and the electrons not used in bonding give rise to metallic properties. ZnO and ZnS are prototypes of the tetrahedrally coordinated wurtzite and zinc blende (or sphalerite) structures in fact, ZnS can adopt either structure, as can CdS and CdSe. HgO and HgS have chain structures with linear two-coordination of Hg. 

The PAHs found on marine sediments may also originate from petroleum. In petroleum, the three- and four-carbon alkyl homologues predominate. Petroleum-derived PAH mixtures are usually very deficient in the unsubstituted parent PAH. 

Unlike the basic Slater function the basic Gaussian function provides a very deficient approximation to a Is atomic radial function. Whereas the Slater function has a nonzero derivative at the nucleus and so can model the cusp of the radial function, the Gaussian function exhibits a zero derivative at the origin [compare the derivatives of... 

Nutrient content well balanced supply of all nutrients very deficient in N, high in K and P, but P unavailable. Micro-nutrients adequate... 

Since the physical make-up of spoil banks varies so widely, it is obvious that the nutrient content also varies similarly. The amount of potentially available potash is likely to be as great as or greater than on nearby undisturbed soils, but the availability may be low. The same is true of phosphorus, but the content of this element is more variable. Since organic matter in new spoils is extremely low, the nitrogen content is also very deficient. It increases as the spoil banks become covered with vegetation, but only very slowly unless much of the plant cover is leguminous. Minor elements are usually present... 

After almost 10 years of aggressive enforcement, Occupational Safety and Health Administration s (OSHA) Hazard Communication rule remains the agency s standard that results in the most numerous fines and penalties. From October 2001 to September 2002, OSHA wrote 2,073 citations for Hazard Communication (HAZCOM) violations that totaled 680,000. The citations occurred because most of the hazard communication programs and their site enforcement were very deficient. In 2010, Hazard Communication violations remained high on the list of the top 10 violated standards and unchanged at number three on the list (Thomas Galassi, 2010, MSDSonline Environmental, Health Safety Blog). 

Most of the genetic variants are loss of function due to splicing, etc. However, one with a single coding change ( 11, Y53C) results in a protein with only 20% of the wild-type catalytic activity towards nifedipine [1472], The 17 allele is also very deficient in activity [1313],... 

Xanthinuria is characterized by a large urinary excretion of oxypurine (xanthine + hypoxanthine) which replaces uric acid at the end product of purine metabolism. Patients with xanthinuria are very deficient in xanthine oxidase activity. This rare metabolic disorder may be of interest for both information ... 

There are other pitfalls in relying upon breads to supply much of one s nutritive needs, since even whole grain products may be very deficient in certain minerals and vitamins. Fig. B-43 shows the nutritional merits and demerits of whole... 

The cinnamon that comes into commerce from Ceylon occurs in three forms, viz. (1) The quills above described (21 the trimminm or cmiramon chips, which are very aromatic and (3) coarse ba as much as an inch thick, the pieces of which are slightly curved longitudinally, and are very deficient in aroma. This bar k is derived from old stools, when they are rooted up, and occurs only in small quantity. The chips or trimmings, which have only been exported since 1867, sometimes form nearly a third of the export of bark, and ar-e used for distilling oil of cinnamon, and are also probably powdered for use in mixed spice. 

Acid-base chemical accidents had already started earlier because of the industrial revolution but, as we know, the attention paid to the workers and risks on the workplace had been very deficient for a long time. 

Dietary sources of copper range from OT mg. Cu per kg. fresh vegetables to 44 mg. per kg. fresh calf liver. The mixed human diet provides O-l to 5 mg. Cu per diem. MUk is usually very deficient in Cu, and Daniels and Wright (1934) suggest that the diet...
