pH Indicators

Maintaining the pH is critical in any industrial processes employing enzymes. A few examples would be papain from the leaves and unripe fruit of the pawpaw (Carica papaya) has been used to tenderise meats. Amylase is used in starch hydrolysis. Now gluco-amylase functions at pH 4.5 whereas fungal amylase at pH 5.5. Lactose hydrolysis is carried out by lactase for Aspergillus niger and A.oryzae at pH optima (pH 4.5-6.0 and 3.0-4.0, respectively) ...

The Effects of Temp & PH on Enzymes
The activity of enzymes is highly affected by changes in pH and temperature and as such each enzyme works best at a given pH and temperature (Jencks, 1987). Changes in pH alter the state of ionization of charged amino acids that may play a crucial role in substrate binding and/or the catalytic action itself. Similarly, hydrogen bonds are easily disrupted by increasing temperature which disrupts the shape of the enzyme such that its affinity for its substrate diminishes (Groves, 1997).

Alligator works as a blind chicken that always find its corns.
These lines that form Alligators Jaw, Teeth and Lips show an interaction of different time periods on the chart. When these three lines join together it means the Alligator is going to sleep or already asleep. As it sleeps it gets hungrier, the longer the sleep the more hungrily it becomes. When it wakes there will be a bullish run and after having a quite full of meal it loses its interest to food/price. "This is the time to fix profit" (Bill Williams, 2006).

Sustainability Indicators
Traditional indicators like stockholder profits, water quality etc. are not holistic in nature since they focus on a particular segment of the community; they do measure the progress of one component as if it was independent from other components of the community. On the other hand, sustainability indicators are resourceful in measuring the interactions of three different aspects of the community i.e. the environment, the economy and the society (Sustainable Measures, 2010). Sustainability indicators (Sis) are those indicators which provide information regarding the feasibility of future goals...
