They note that out of 11 recessions in the United States since World War 2, ten were preceded by oil price spikes: "The increased price of oil leads to a sudden loss of demand (demand destruction) followed by a decrease in the price of oil (countering the initial increase that set this cycle in motion).
Again, increased periodontal destruction was not necessarily followed by a decrease in the amount of dentin- and pulp-like tissue formed.
All three elements exhibit a rapid increase in the dissolution rate followed by a decrease in the rate as they sorb to or co-precipitate with oxide substrates.
The competition for these active sites may even increase, followed by a decrease in the adsorption efficiency (Puranik and Paknikar 1999; Singha and Das 2011).
It can also be observed that by increasing the MWCNTs content, there is an increase followed by a decrease in the mechanical properties.
In CV studies, in the presence of methanol the peak current of the oxidation of cobalt hydroxide increase is followed by a decrease in the corresponding cathodic current.
The peak current of the oxidation of nickel hydroxide increase is followed by a decrease in the corresponding cathodic current in presence of methanol.
Addition of more B (27 at.% or more) produced smaller and more uniform nanocrystallites, followed by a decrease in the distribution density of nanocrystallites in the amorphous matrix.
Voltammetric studies indicated that in the presence of drugs, the anodic peak current of low-valence nickel species increases, followed by a decrease in the corresponding cathodic current.
Interestingly, a significant increase in superoxide dismutase (SOD, 264.2%), and peroxidase (POX, 182.8%) enzyme activities followed by a decrease in the catalase (CAT) activity, in response to above treatments.
In the case of 250 mg/L of naphthalene, the CFU increased for a few days, after which the growth ceased followed by a decrease in the total cfu/mL.
