The diffraction pattern was scanned from 2 Theta ranges of 4 to 50o at a scanning rate of 1o/min. Scanning electron microscopy (SEM) The morphological characteristics of samples i.e. ISR, neusilin and optimized SNEP were investigated using a scanning electron microscope (SEM, S-4100, Hitachi, Japan) at an accelerating voltage of 15 Kv. Double-sided sticky tape with lightly sprinkled sample was affixed to aluminum stub and made electrically conductive with gold coating (3-5 nm/min... ... middle of paper ... ... drug concentration–time profile i.e., (AUC) was obtained by using trapezoidal rule. The peak drug concentration (Cmax) and the time to reach the peak drug concentration (Tmax) were obtained from the experimental data.
By observing the plant life in an ecosystem we can predict the following heterotroph factors, as autotrophs are the providers of all energy. Through understanding ecosystems we see that they provide us with essential chemical cycles and by understanding these we see relevance for understanding ecosystems in todays society. Materials and Method: Choose a site that is at least 32m squared and has a constant naturally occurring ecosystem. This can include sites like • Parks. • Bush land.
Nutrient cycling is passed from trophic level to trophic level and from ecosystem to ecosystem via consumption, translocation, fecal matter, and decomposition (Reece & Campbell 2011, Vanni 2002, & Hammer & Holmlund 1999). The nutrients often undergo many transformations from one chemical form to another (Vanni 2002). Ecologist Camille Parmesan explains the importance of biodiversity in an ecosystem and its benefits, such as breathable air being the result of plants and microorganisms (Reece & Campbell 2011). How efficient an ecosystem processes depends on the species present (Giller et al 2004). Energy flow, nutrient cycling, and biodiversity each a play a critical role in the regulation of ecosystems.
Energy Flux in Ecological Systems The concept of ecology considers interactions between organisms and their environment across several scales of analysis. Population ecology includes investigations of the physiological principles that modulate how individuals interact with their environment, and resource competition theory that explores the dynamics of both individual and interacting species. Community ecology focuses on large assemblages of species and considers how in fluxes of matter and energy can define collections of species within an ecosystem. Consequently, the concept of an ecosystem must consider how nutrient cycles shape the rate and efficiency of energy transfer among and between species and communities. This essay will attempt to highlight the key role of energy transfer across varying levels of complexity in ecology.
It takes into account the carrying capacity for an ecosystem, and how many people can use up the land in that ecosystem to survive at a decent level. Another source provides the actual mathematical equation for the ecological foot print analysis: “EF= P/YN*YF*EQF, where P is the amount of a product harvested or waste emitted, YN is the national average yield for P, YF is the yield factor, and EQF is the equivalence factor”, (Zakari, R., Zolfagharian, S., Nourbakhsh, M., Zin, R. M., & Gheisari, M. (2012)). The carrying capacity of the human race is the maximum rate of resource consumption and waste production. To determine the total ecological footprint as a whole, we add up all the mutually exclusive zones of land use: pasture land, agricultural
Debt Collection Period Meaning, Objective and Method of Calculation: - 1. Capital Turnover Ratio: Capital turnover ratio establishes a relationship between net sales and capital employed. The ratio indicates the times by which the capital employed is used to generate sales. It is calculated as follows: - Capital Turnover Ratio = Net Sales/Capital Employed Where Net Sales = Sales – Sales Return Capital Employed = Share Capital (Equity + Preference) + Reserves and Surplus + Long-term Loans – Fictitious Assets. Objective and Significance: The objective of capital turnover ratio is to calculate how efficiently the capital invested in the business is being used and how many times the capital is turned into sales.
Real GDP measures the output of actual goods and services produced in an economy (Miskin,2012). The measurement of actual goods and services produced means that there has been an adjustment for constant price changes i.e. inflation. Nominal GDP (measured at current prices which does not truly reflect the activities of an economy over time) is transformed by this adjustment into an index for quantity of total output. Real GDP takes into account inflation which measures the actual increase in goods and services and excludes the impact of rising prices (http://economicshelp.org/blog/glossary/real-gdp-capita).
Chapter nine entitled “Receivables” (2014, p. 407) further explains: “The preceding adjusting entry affects the income statement and the balance sheet”. Ultimately, the adjustment to accounts receivables decreases the value to $360,000; computed as $400,000 - $40,000 = $360,000. This new value is called the net realizable value of accounts receivable for the period ending December 31st. Part Two - Depreciation In order to affirm the value of a fixed asset, on the balance sheet, depreciation is used to show the asset’s true value. There are three methods for estimating depreciation expense; straight-line method, units-of-output method, and, double-declining-balance.
