The phrase "an observable decrease in" is correct and usable in written English.
It can be used when discussing measurable changes or trends in a particular variable or phenomenon.
Example: "The study revealed an observable decrease in the population of the species over the last decade."
Alternatives: "a noticeable decline in" or "a measurable reduction in".
The chance of finding an observable decrease in entropy for an isolated system can be ruled out.
The test concluded that each woman had an "observable decrease in the appearance of wrinkles" around the eyes ranging from 50 to 90percentt.
Achieving this improved functionality often requires laser processing of the SMA's with a high-energy pulse coupled with an observable decrease in the corrosion resistance, however there are discrepancies in the post-processing corrosion performance.
There should be an observable decrease in the Income per Capita histogram, indicating a correlation between level of education and income.
Importantly, the virus persisted for weeks in the male reproductive tract after the initial infection, and led to an observable decrease in testes size (Govero, Esakky et al. 2016) (Ma, Li et al. 2016).
Both types of interaction lead to an observable decrease in TFAl species and a reduction in Brønsted acid sites, as we will discuss in the following sections.
The CeO2 catalyst showed high stability and did not exhibit any observable decrease in the HDC yield or any structural changes after four recycling periods.
Furthermore, the Pd/C catalyst was shown to be recyclable up to 6 times without any observable decrease in efficiency and it exhibited low metal leaching under the reaction conditions.
There is an observable decrease of cathodic current in the second CV compared with the first CV for the TiO2 electrode, which agrees with the previous report on TiO2 anode materials and can be attributed to the irreversible lithium insertion-deinsertion reaction, indicating a large capacity loss during the first two cycles.
In contrast to younger animals (Fig. 2B,C), we found a readily observable decrease in TH-positive fibers in the SNpC of Id2−/− individuals at 6 months of age (Fig. 2D), correlating with their reduced physical activity (Fig. 1).
The accepted resolution of this contradiction is that the length of time such a system must operate in order that an observable decrease of entropy may occur is so enormously long that a decrease could never be verified experimentally.
