Approximately 15 per cent of osteoblasts become entrapped in their own matrix to become osteocytes. Osteocytes have a vast three-dimensional network of cell processes (canaliculi), providing nourishment and cell-cell interactions. Because they are located throughout bone tissue and have an extensive canalicular network, osteocytes are assumed to be a vital component of sensing mechanical signals. Nutrients are essential for the vitality of bone tissue and are obtained from the blood supply, limiting most osteocytes to lie within 150 p.m of a blood vessel, resulting in a high cellular density 25000 osteocytes within a square millimetre of bone... 

The first of the four characteristic currents to J4 has a prominent position. It indicates the crossover from a charge supply limited reaction to a kmetically and mass transfer limited reaction. This crossover is accompanied by pronounced changes in charge state, chemical dissolution reaction, dissolution valence, pore formation and anodic oxide formation. Therefore its dependence on other parameters, such as crystal orientation, temperature or H F concentration deserves further investigation. In the literature Jt is usually termed /crl JPS or JPSL. In the following the symbol JPS will be used. 

The yellow self-adhesive Accutane qualification sticker documents that the female patient is qualified and includes the date of qualification, patient gender, cut-off date for filling the prescription, and up to a 30-day supply limit with no refills. 

LPG is a blend of propane and butane obtained as secondary products of natural-gas exploration or during crude oil processing. For this reason LPG is included usually in alternative fuels. Although the combustion properties of LPG are excellent, its wider usage is prevented by supply limitations and safety problems. 

When the volume of the compartment being cleared is constant, the assumption that the fractional flow rate is constant is equivalent to assuming that the clearance is constant. But in the general case, in which the volume of distribution cannot be assumed constant, the use of the fractional flow rates k is unsuitable, because the magnitude of k depends as much upon the volume of the compartment as it does upon the effectiveness of the process of removal. In contrast, the clearance depends only upon the overall effectiveness of removal, and can be used to characterize any process of removal whether it be constant or changing, capacity-limited or supply-limited [308].

Growing Conditions. Foods must be highly enriched with stable isotopes to be useful as labels for bioavailability experiments in order to accurately distinguish the label from naturally occuring isotopes. However, stable isotopes are expensive and their supply limited. Therefore, the labeling methodology must be as efficient as possible. 

That is the advantage of fission. Its drawback is the deadly radioactivity it generates, particles whose mass, from one type of reactor, is almost equal to the mass of the fuel consumed. Waste from a fission reactor typically requires thousands of years before it breaks down into biologically safe levels. Fission reactors are also relatively inefficient. They can use but a single isotope (atoms of an element that have the same number of protons but a different number of neutrons) of uranium, U-235, which makes up less than 1 percent of natural uranium ore. (More than 99 percent of natural uranium is nonfissionable U-238.) So-called fast breeder reactors might overcome the supply limitation by breeding fissionable fuel from U-238. But the fuel it produces from the uranium is plutonium, the same stuff that was inside the Nagasaki bomb—not an ideal by-product in a politically unstable world. 

For emergency supply at the request of a patient, up to five days supply may be made (except in certain circumstances) (also see point 5 below). However, consideration should be given to supplying less than five days. Emergency supply at the request of a practitioner has no supply limit, although professional judgement should be exercised if the requested quantity appears excessive. 

The role of Fe as a limiting nutrient has been well established in the last decade in the so-called high-nutrient low chlorophyll regions of the oceans. A series of massive iron seeding experiments carried out to test the iron hypothesis advanced by Martin and Fitzwater (1988) have unequivocally shown that iron supply limits plankton production in one third of the world s oceans, despite the perennially high surface concentration of macronutrients (Fig. 7.1). The dynamics of phytoplankton blooms are limited by iron supply, which... 

This scaling is irrelevant mathematically, but it keeps the variables in a more favorable range for electronic implementation, if one unit is supposed to correspond to one volt. Otherwise the wide dynamic range of the solutions exceeds typical power supply limits.)... 

A new permit with the state of New Mexico will require this liquid stream to meet the domestic water supply limit for dissolved NO3 of 10 mg/L measured as N (in order to comply with the federal Clean Water Act and the New Mexico Water Quality Act). A nitric-acid fractionation (distillation column) is to be installed to recover these nitrates from the discard stream prior to disposal. The column (Figure 4.22) will include a total condenser and partial reboiler and will operate with a reflux ratio of 0.4. 

There are many equations which allow calculation of sediment transport rate within a water body, or sediment flux (see for example Task Committee of Computational Modeling of Sediment Transport Processes, 2004 for a review). However, these equations tend to be for a uniform sediment distribution, which is far from the variable source supply of material seen in events when the majority of sediment is moving. It is also generally considered that a particular flow has a maximum capacity to transport sediment, although the concentration this relates to depends again on sediment characteristics. Hence tliere are examples in China where sediment concentrations can reach several tens of thousands of parts per million for very fine particles, whereas a flow may become saturated with sand-sized particles at far lower concentrations. Rivers are often considered to be either capacity- or supply-limited in terms of their sediment transporting dynamics. However, in practice for most rivers, most of the time, sediment transport is limited by a complex and dynamic pattern of sediment supply. 

The water storage capacity of soil depends variably on the two values of S (i.e., the lower or wet limit and the upper or dry limit) chosen for the computation (Table 2). Our purpose is to estimate the ejuantity of water available for evaporation over a range where it is not supply limited. Thus, we wish to epantify the supply variable. We advocate a lower S limit of 10 kPa. This value is analogous to the so-called field capacity In terms of the associated 6, it is generally the wettest a soil can become because drainage then...
