A method for determining the recombination rate constant ( k t) of electrochemically induced acrylonitrile polymerization based on the internal reflection spectrum of the polymerization system is proposed. The changes in the intensity of the absorption band at 2165 cm 1 due to the acrylonitrile anion...
awhere Wc is the work of inception of a viable vapor nucleus, N1 is the number of molecules in a unit volume of the metastable phase, B is the kinetic coefficient determining the rate of molecule attachment to the nucleus of the new phase, and k is the Boltzmann constant。 那里Wc是一个...
Therefore, the goal of the present study was to determine the thermal characteristics of breast cancer by constructing a computational thermal (or bioheat) model calibrated to real clinical data. Specifically, the study aimed to quantify the thermal characteristics—i.e., blood perfusion rate,\({\...

(Bernanke,2013; Slade,2015; Yellen,2013). Changes in key variables driving the global economy such as interest rate, monetary policy, taxes, and federal debts and investment levels may have effects on the economy at least three quarters ahead. The evolution of economy, due to the changes in...
HTML Purpose: To determine the false positive rate (specificity) of a new MRI-based method for simultaneous measurement of total cerebral blood flow (TCBF), and intracranial pressure (MR-ICP) in healthy adults. A low positive rate is a prerequisite for a large scale evaluation of the method...
The rate of convergence is also greatest when the sample size is low, and decreases with increasing sample size. There are 3 occasions where the range in CI increases with an increasing step size: the ETIa CI range is greater when Ni = 100,000 than when Ni = 30,000, the RET CI ...
The assumptions of the pseudophase model for chemical reactivity in homogeneous microemulsions are used to determine the distribution of α-tocopherol (TOC) in macroemulsions from changes in the observed rate constant ( k obs) for reaction between 4-hexadecylarenediazonium ion (16-ArN 2 +) probe...
Therefore, here we suggest to analyze the rate of TEC change (dTEC/dt) instead of the sTEC. Such a derivative procedure works as a high-pass filter and removes the bias and trend caused by the satellite orbit motion. In addition, our dTEC/dt approach will not modify the amplitude of ...
With regards to the population growth rate of people aged above 65 years old, which is reported to be 15.1%, the number of patients with cataract will increase4. On the other hand, keratoconus patients are more likely to get cataract than non-keratoconus patients5. Therefore, it is necessary...
