(3) Considering the time dependence of chloride
diffusion coefficient, it is apparent that chloride
diffusion coefficient [D.sub.a] was used when predicting the chloride ingress in concrete.
where D is the chloride
diffusion coefficient of mortar, C is the chloride concentration at any time, and t is a function of depth, x.
For mortars with a different sand content, the measured geometric factors for [Li.sup.+], [Cl.sup.-], and HTO are relatively similar, leading to the conclusion that the formation factor can be used to determine the order of magnitude of the effective
diffusion coefficient of other diffusion species [36].
The mean apparent
diffusion coefficient value of the malignant breast lesions was significantly lower than that of the benign breast lesions (p-value<0.001).
Keywords: Magnetic resonance imaging, parotid glands, diffusion weighted imaging, apparent
diffusion coefficient(2004), the diffusion rate decreases, reducing the effective
diffusion coefficient when the water and sucrose concentration inside the fruit become close to reaching the equilibrium value.
Finally, apparent
diffusion coefficient (ADC) values were extracted from MRI data.
Inverse correlation between choline magnetic resonance spectroscopy signal intensity and the apparent
diffusion coefficient in human glioma.
The
diffusion coefficient (D), in transient state, can be measured through various different methods as found in the literature.
The
diffusion coefficient of each ionic species has the following relation with tortuosity [15]:
For the surgical and treatment planning a diagnostic method is highly desirable for accurate distinction between benign and malignant meningiomas.12 Diffusion weighted imaging (DWI) along with the calculation of apparent
diffusion coefficient (ADC), is a reliable and non-invasive technique of choice for accurate assessment and in treatment planning of different types of brain tumors.
