Description This function calculates the coefficient of variation for each gene in the qPCR experiment, and returns the average coefficient of variation across all genes.

the study was designed to investigate the income distribution among rice-based farming households in okigwe agricultural zone of imo state, nigeria. a sample of 120 rice-based farmers was selected by multistage sampling technique. data were collected with a well structured questionnaire administered to 120 randomly selected rice farmers. data collected were analyzed using descriptive statistics...

chamomile (matricaria chamomilla), an important medicinal plant belonging to the asteraceae family,has a wide distribution in iran and other parts of the world. the medicinal and pharmacological effects ofchamomile are mainly associated with its essential oil content and it is widely used in food, cosmetics andpharmaceutical industries. despite its wide geographical distribution in iran, little...

system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...

Simple network-level measures can tell us a great deal about the shape of a network, e.g., the mean degree, the degree distribution, local or global clustering coefficients, edge reciprocity, mean geodesic distance or diameter, etc. However, these simple measures are not sensitive to how the structural pattern they measure might vary non-uniformly across the network. For example, reciprocity te...

Strategies for the deconvolution of diffusion in the determination of size-distributions from sedimentation velocity experiments were examined and developed. On the basis of four different model systems, we studied the differential apparent sedimentation coefficient distributions by the time-derivative method, g(s*), and by least-squares direct boundary modeling, ls-g*(s), the integral sediment...

A new method was developed for the analysis of fluorescein exchange between the aqueous humor and cornea which enables calculation of the permeability coefficient of the corneal endothelium and the steady-state aqueous-cornea distribution ratio from one experiment. After intravenous fluorescein injection, aqueous and corneal fluorescence was measured at intervals, using an objective fluorophoto...

background & aim: increasing economic role of medicinal herbs in recent society and complexity of modern technologies in production (planting and harvesting), transportation, storage, processing, quality evaluation, distribution, marketing and consumption of these products require a thorough understanding of their physical properties. coefficient of friction of plant on the various surfaces...

In this paper, we studied the research areas of Chinese natural science basic research from a point view of complex network. Two research areas are considered to be connected if they appear in one fund proposal. The explicit network of such connections using data from 1999 to 2004 is constructed. The analysis of the real data shows that the degree distribution of the research areas network (RAN...
