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 Com-mittee E-18 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.
Before entering into any investment, the risk of that venture must be identified and quantified. The Handbook of Risk provides in-depth coverage of risk from every possible angle and illuminates the subject by covering the quantitative and and behavioral issues faced by investment professionals on a day-to-day basis. This valuable reference offers a prescriptive and descriptive treatment of risk management for those looking to control, contain, and minimize the risk of their investments.
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 socio-political instability in one country: Côte d’Ivoire.
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.
In this chapter students will be able to: Select and develop the appropriate research design for your hypotheses or research questions; understand the strengths and limitations of each design form as it relates to research fi ndings, and argue for your design choices; explain the benefi ts of experimental forms over quasi-experimental and descriptive forms;
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 ligh-driven 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
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.
Moreover, alternative methodologies would be helpful in cross-
checking the validity of our results. Beside our quantitative results, our main con-
tribution relies in the description of a mechanism through which cloud computing
is likely to create a positive effect on GDP, employment and business creation.
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....
