The structure of phenylcyclopropane radical cation (1•+, R ) H) is derived from CIDNP effects observed during the electron transfer reaction of 1 with chloranil. This species is an example of an elusive structure type. The secondary cyclopropane protons show significantly divergent hyperfine coupling constants due to an unprecedented stereoelectronic effect. Incorporation into a redox-active pe...

A number of physical factors can adversely affect cultural heritage. Therefore, monitoring parameters involved in the deterioration process, principally temperature and relative humidity, is useful for preventive conservation. In this study, a total of 15 microclimate stations using open source hardware were developed and stationed at the Mosque-Cathedral of Córdoba, which is registered with UN...

Fig. 1 (a) Plots of Kinetic parameters (K, ve, kep, IAUC) vs. assumed baseline T1 when a true T1=800 ms with K trans = 0.5min, IAUC = 0.039 M⋅s, kep = 1.25 min , and ve = 0.4. (b) Plots of the normalized ratios (NR) of IAUC, kep, K trans and ve. True NRs are 0.77, 0.6, 0.5 and 0.125, respectively. The same true T1 (800 ms) was assumed for both preand post-treatment. Fig. 2. Effects caused by th...

The single source localization problem (SSLP) appears in several fields such as signal processing and global positioning systems. optimization of SSLP is nonconvex difficult to find its globally optimal solution. It can be reformulated a rank constrained Euclidean distance matrix (EDM) completion with number equality constraints. In this paper, we propose facial reduction approach solve an EDM ...

The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...

The Dynamic Voltage Restorer (DVR) is a commercially available, popular device to eliminate voltage sags and swells in the distribution lines. Its basic function is to inject the voltage difference (difference between the pre-sag and sag voltage) to the power line and maintains the pre-sag voltage condition in the load side. The efficiency of the DVR depends on the performance of the efficiency...
