Orders size, average

The main component of E. coli—as in all cells—is water (70%). The other components are macromolecules (proteins, nucleic acids, polysaccharides), small organic molecules, and inorganic ions. The majority of the macromolecules are proteins, which represent ca. 55% of the dry mass of the cell. When a number of assumptions are made about the distribution and size (average mass 40 kDa) of proteins, it can be estimated that there are approximately 250000 protein molecules in the cytoplasm of an E. coli cell. In eukaryotic cells, which are about a thousand times larger, it is estimated that the number of protein molecules is in the order of several billion.

In order to average over the environmental variable, we integrate the differential equation (7.3.15) with respect to y. If we define the event that at time t there is a particle in the population of size x by A (t), then the result...

Average order size measures the average quantity per order. The average sale price, order size, incranental fixed cost per order, and iuCTemental variable cost per unit help estimate the contribution from performing the supply chain activity. 

Weekly demand for gaming consoles at Liverpool, a Mexican department store chain, is normally distrihnted with a mean of 1,000 and a standard deviation of 400. The replenishment lead time from the suppher is four weeks. Liverpool is targeting a CSL of 95 percent and uses a periodic review policy under which it reorders consoles every eight weeks. What is the average order size How much safety inventory of consoles should Liverpool carry What should its order up to level be How much safety inventory would be required if Liverpool switched to a continuous review policy ... 

A system of interest may be macroscopically homogeneous or inliomogeneous. The inliomogeneity may arise on account of interfaces between coexisting phases in a system or due to the system s finite size and proximity to its external surface. Near the surfaces and interfaces, the system s translational synnnetry is broken this has important consequences. The spatial structure of an inliomogeneous system is its average equilibrium property and has to be incorporated in the overall theoretical stnicture, in order to study spatio-temporal correlations due to themial fluctuations around an inliomogeneous spatial profile. This is also illustrated in section A3.3.2. 

The time-dependent structure factor S k,t), which is proportional to the intensity I k,t) measured in an elastic scattering experiment, is a measure of the strength of the spatial correlations in the ordering system with wavenumber k at time t. It exliibits a peak whose position is inversely proportional to the average domain size. As the system phase separates (orders) the peak moves towards increasingly smaller wavenumbers (see figure A3.3.3. 

Islands occur particularly with adsorbates that aggregate into two-dimensional assemblies on a substrate, leaving bare substrate patches exposed between these islands. Diffraction spots, especially fractional-order spots if the adsorbate fonns a superlattice within these islands, acquire a width that depends inversely on tire average island diameter. If the islands are systematically anisotropic in size, with a long dimension primarily in one surface direction, the diffraction spots are also anisotropic, with a small width in that direction. Knowing the island size and shape gives valuable infonnation regarding the mechanisms of phase transitions, which in turn pemiit one to leam about the adsorbate-adsorbate interactions.
