Slow growth rate

Parallel to the activities in the treatment of pernicious anemia were observations in the 1930s that most farm animals had a requirement for an unknown factor beyond the vitamins then known. The lack of this factor became apparent, eg, when chicks or pigs fed a diet with only vegetable protein evidenced slow growth rate and high mortahty. It became apparent that the requited factor, termed animal protein factor, was present in animal sources such as meat and tissue extracts, milk whey, and cow manure. Subsequent to its isolation, it was rapidly shown that vitamin B 2 is the same as animal protein factor. 

Note, however, that this calculation involves an assumption that either the °Thxs and/or the °Thxs/ Th remains constant at the outer surface of the nodule throughout its growth. That this is not exactly hue is shown by the fact that the growth rate history for the crast is not identical using the two chronometers. For instance, the outermost three Thxs data imply a slow growth rate, while the same three points, when normalized to Th, imply a rapid growth rate. The problem of variable inihal conditions limits the usefulness of °Thxs dating of Mn nodules and crasts. 

L airlift bioreactor respectively [130]. The slow growth rate of plant cells leads to a high possibility of contamination during the cell culture, thereby increasing the production cost. Thus, efforts have been made towards alternative hosts, like engineering microbes to produce Taxol. 

MBE (molecular beam epitaxy), which involves epitaxial growth of thin films on either the same material as substrate (homoepitaxial) or a lattice-matched substrate (heteroepitaxial) the heated substrate reacts with a molecular beam of compounds containing the constituent elements of the semiconductor as well as any dopants the resultant film is essentially a single crystal slow growth rates produce films from a few nanometers thick to at most several hundred nanometers that have very high purity and controlled levels of dopants. 

Both steps are influenced by dissolved oxygen and the corresponding substrate concentration. The nitrification as a wastewater treatment process benefits greatly from biomass retention, owing to the relatively slow growth rates of the nitrifiers. 

The major drawbacks to standard sol-gel synthesis include slow growth rate and the typically amorphous product, rather than defined crystals, which requires crystallization and post annealing steps. Growth rate and crystallization of the fabricated hybrid can be improved via solvothermal, reflux [224], sonication, and microwave [225] treatment. However, the air oxidation of CNTs (600 °C) and graphene (450 °C) may still be lower than MO crystallization temperature. Moreover, it has been shown that the MO coatings on CNTs can drastically affect their thermal oxidation, particularly with easily reducible metal oxides (e.g. TiOz = 520 °C, Bi203 = 330 °C) [180]. It appears that metal oxides can catalyze the oxidation of CNTs via a Mars van Krevelen mechanism, limiting the maximum temperature of their synthesis as well as applications (i.e. catalysis, fuel cells).

Prostatic Adenocarcinoma. For prostatic adenocarcinomas, their typical slow growth rate and low cycling fraction provide a logical radiobiological rationale for exploring neutrons (high LET) in the treatment of this disease.

Slow growth rates of graft radicals indicate that effective concentrations of monomer around active ends of graft radicals are quite low. The rate-determining step would be the diffusion of monomer molecules within and around the surface of microcrystals. Hence, it would be reasonable to assume that growth rate of graft radicals within crystalline parts is much slower than those located outside throughout reactions. 

In fact, it is far less in view of the rigidity of the physical-chemical conditions to be satisfied to make their simultaneous occurrence possible. Therefore, at least for a short while, one of the layers will almost always occur at the A-B interface earlier than the other. The absence of one of the layers is thus a physical reality. To explain this phenomenon, there is no need to invoke additional causes like difficulties with nucleating new phases or too slow growth rates producing invisible compound layers. 

So where are they today In industry, these numbers are very hard to come by. Madeleine Jacobs, editor in chief of C EN, took the approach of perusing the annual reports of the top U.S. chemical companies. In 1997, only 4 percent of the upper management listed in the annual reports of the top 19 U.S. chemical producers were women, with the majority of these holding staff titles. Numbers on technical staff are virtually impossible to find. A 1998 study of Fortune 500 corporations by Catalyst, the nonprofit organization that aims at maximizing opportunities for women in management and executive positions, showed that fewer than 4 percent of the chairman, CEO, and VP titles were held by women. Only 11.2 percent of corporate officers were women, and they projected very slow growth rates (13 percent in 2000, 17 percent in 2005).
