Description

This function describes the evolution of the probability of single-cell growth with environmental factors (T, pH & aw). For this, we used the model proposed by Jean Christophe Augustin and Aurelia Czarnecka-Kwasiborski in 2012, to describe the combined effect of the three environmental factors. in this model T, pH and aw were considered to have independent effects on the single cell

Usage

Proba_c(T, Tinf, Tsup, c, pH, pHinf, pHsup, aw, awinf, awsup)

Arguments

T	Temperature value # a number
Tinf	The theoritical cellular minimal temperature for growth #a number
Tsup	The theoritical cellular maximal temperature for growth #a number
c	Parameter # a number
pH	pH value # a number
pHinf	The cellular minimal pH for growth # a number
pHsup	The cellular maximal pH for growth # a number
aw	water activity value #a number
awinf	The cellular minimal value of aw for growth # a number
awsup	The cellular maximal value of aw for growth # a number

Details

\begin{equation}p≤ft(T, \mathrm{pH}, a_{w}\right)=p(T) \cdot p(\mathrm{pH}) \cdot p≤ft(\mathrm{a}_{\mathrm{w}}\right)\end{equation}

Value

Pc The single-cell growth probability as function of environemental factors # a number

Examples

Proba_c(10,Tinf=-3.6,Tsup=17.3,5,c=7.6,pHinf=-4.34,pHsup=5.93,0.95,awinf=0.917,awsup=0.988)
