The quantitative description

At the time of his death, Petrie had completed early drafts of two or three chapters of a book which was to have been called 'The Developmental Physiology of Plants', and the above quotation from Plato had been placed at the beginning of Chapter 2, 'The Change in Dry Weight and Leaf Area, and First Steps in the Analysis of Growth Rate'. Unfortunately the book had not reached a stage from which it could have been completed by any of his colleagues, and we had to content ourselves with placing the quotation on the title page of a bound volume of Petrie's papers in plant physiology for the...

The Manual on Descriptive Analysis Testing for Sensory Evaluation was sponsored by Committee E18 on Sensory Evaluation. Descriptive analysis is a sensory method by which the attributes of a food or product are identified and quantified, using human subjects who have been specifically trained for this purpose.

Information Theory, Evolution, and the Origin of Life presents a timely introduction to the use of information theory and coding theory in molecular biology. The genetical information system, because it is linear and digital, resembles the algorithmic language of computers. George Gamow pointed out that the application of Shannon’s information theory breaks genetics and molecular biology out of the descriptive mode into the quantitative mode, and Dr. Yockey develops this theme, discussing how information theory and coding theory can be applied to molecular biology....

World cocoa price has fallen by some 48% over the past three years, with direct impacts on the incomes, health and nutrition of cocoa producers and their family in the two major producing countries: Côte d’Ivoire and Ghana, with some 41% and 22% of world output, respectively. The impact of the price drop has been far different in the two countries because of the greater age of plantations, market liberalisation, presence of free agents in the marketing channel, and much greater sociopolitical instability in one country: Côte d’Ivoire.

Thermoelectric Thermometers Physical Principles Thermoelectric force It was T. Seebeck who discovered, in 1821, the effect which now bears his name . He observed that a current flows in a closed loop oftwo dissimilar metals when theirjunctions are at two different temperatures. As Ohm's law was not formulated by G. S. Ohm until 1826, the quantitative description of this phenomenon was not possible at the time of its discovery . In 1834, I.C.A.

A univariate descriptive analysis of the quantitative survey data was undertaken to summarise the results for each question. Data was recoded by combining categories as required to facilitate a subsequent bivariate analysis aimed at identifying patterns within the data. Distributions of the respondents’ demographic variables were cross tabulated with their attitudinal variables and future orientation variables. The coefficients phi, Cramer’s V and Goodman and Kruskal’s gamma were used to measure associations between variables as appropriate.

Finance has become increasingly more quantitative, drawing on techniques in probability and statistics that many finance practitioners have not had exposure to before. In order to keep up, you need a firm understanding of this discipline. Probability and Statistics for Finance addresses this issue by showing you how to apply quantitative methods to portfolios, and in all matter of your practices, in a clear, concise manner. Informative and accessible, this guide starts off with the basics and builds to an intermediate level of mastery. ...

Food engineering is usually a difficult discipline for food science students because they are more used to qualitative rather than to quantitative descriptions of food processing operations. Food engineering requires understanding of the basic principles of fluid flow, heat transfer, and mass transfer phenomena and application of these principles to unit operations which are frequently used in food processing, e.g., evaporation, drying, thermal processing, cooling and freezing, etc. The most difficult part of a course in food engineering is often considered the solution of problems.

More recently, a QSAR (Quantitative Structure Activity Relantionship) investigation was carried out on a series of nostoclide analogues presenting the general structure (43) to correlate molecular descriptions with their in vitro biological activity (the ability to interfere with lighdriven reduction of ferrycianide by isolated spinach chloroplasts thylakoid membranes). The results of this investigation suggested that the degree of inhibition efficiency of this class of compounds is intimately associated with their polarity (Teixeira et al, 2009).

The gender gap in each dimension is then quantified using two types of recent available data: a) published national statistics and data from international organizations, and b) survey data of a qualitative nature from the annual Executive Opinion Survey of the World Economic Forum. Following, is a brief description of each of the five categories and the rationale behind them. Details of the specific variables examined and their sources may be found in the Appendix.

We have analyzed several mathematical models that describe inhibition of the factor VIIa–tissue factor complex (VIIa–TF) by tissue factor pathway inhibitor (TFPI). At the core of these models is a common mechanism of TFPI action suggesting that only the Xa–TFPI complex is the inhibitor of the extrinsic tenase activity. However, the model based on this hypothesis could not explain well all the available experimental data. Here, we show that a good quantitative description of all experimental data could be achieved in a model that contains two more assumptions....
