The number of cytokines known to influence hematopoiesis is steadily growing. The most recently identified cytokines are SDF-1 [38], VEGF2 [39] and SCEPF [40],but there are still growth factors in the stromal environment to be identified. This has been proven by the additional growth-supportive effects of stroma-conditioned medium on the proliferation of hematopoietic stem cells. 

We illustrate the molecular dynamics technique by application to the ion beam deposition technique. Molecular dynamics could be used to investigate the effect of deposition conditions on the microstructure of the growing film. The microstructural characteristics of interest include film roughness and porosity.

Fig. 17. Effect of various conditions on mitochondrial density. Mitochondria were sedimented to equilibrium on linear sucrose gradients. After fractionation, the gradients were analyzed for cytochrome oxidase activity and density. (A) Mitochondria from growing cells. (B) Mitochrondria from cells starved for 1 h. (C) Mitochondria from growing cells washed with 2 mM EDTA. (D) Same as (C), except mitochondria were incubated with PH]-labeled ribosomes before centrifugation. (E) Mitochondria from growing cells. Culture was pretreated with 200 Mg/ml cycloheximide prior to harvesting. (F) Mitochondria from growing cells treated with 200 Mg/ml cycloheximide, then starved for 1 h.

Additives, whether hydrophobic solutes, other surfactants or polymers, tend to nucleate micelles at concentrations lower than in the absence of additive. Due to this nucleating effect of polymers on micellization there is often a measurable erne, usually called a critical aggregation concentration or cac, below the regular erne observed in the absence of added polymer. This cac is usually independent of polymer concentration. The size of these aggregates is usually smaller than that of free micelles, and this size tends to be small even in the presence of added salt (conditions where free micelles tend to grow in size). 

The compound R X is a chain-transfer agent, with X usually H or Cl. The net effect of chain transfer is to kill a growing chain and start a new one in its place, thus shortening the chains. Mercaptan chain-transfer agents ate often used to limit molecular weight, but under appropriate conditions, almost anything in the reaction mass (solvent, dead polymer, initiator) can act as a chain-transfer agent to a certain extent. 

The use of vitamins in humans consumes ca 40% of vitamins made worldwide. The majority of the vitamins, particularly in countries outside the United States, are used in animal husbandry. It is well estabUshed (21) that vitamins are critical to animal productivity, especially under confined, rapid growth conditions. Newer information (22) has shown that vitamin E added to catde feed has the additional effect of significantly prolonging beef shelf life in stores. Additional appHcations of vitamins exist. A small but growing market segment involves cosmetics (qv) (23). The use of the chemical properties of the vitamins, particularly as antioxidants (qv) in foods and, more recently, in plastics (vitamin E (24)), has emerged as a growing trend. 

The effect of ozone is complicated in so far as its effect is largely at or near the surface and is of greatest consequence in lightly stressed rubbers. Cracks are formed with an axis perpendicular to the applied stress and the number of cracks increases with the extent of stress. The greatest effect occurs when there are only a few cracks which grow in size without the interference of neighbouring cracks and this may lead to catastrophic failure. Under static conditions of service the use of hydrocarbon waxes which bloom to the surface because of their crystalline nature give some protection but where dynamic conditions are encountered the saturated hydrocarbon waxes are usually used in conjunction with an antiozonant. To date the most effective of these are secondary alkyl-aryl-p-phenylenediamines such as /V-isopropyl-jV-phenyl-p-phenylenediamine (IPPD). 

Work carried out by Gilbert on irons maintained at 500°C for 64 weeks (Fig. 7.15) has shown that in ordinary unalloyed flake irons graphitisation and oxidation cause roughly equal amounts of growth, and that as the carbon content increases the effect of oxidation becomes more important and the overall rate of growth increases. Nodular graphite irons grow very slowly under these conditions.
