introduction several hundred pesticides of different chemical compositions are currently used for agricultural and vector control purposes all over the world. because of their extensive use, they are detected in various environmental matrices, such as soil, water, and air. due to their lipophilic nature, hydrophobicity, and low chemical and biological degradation rates, organochlorine pesticide...

We present here a review of high energy (> 1 keV) observations of seven black hole candidates , six of which have estimated masses. In this review we focus on two parameters of interest: the ratio of \non-thermal" to total luminosity as a function of the total luminosity divided by the Eddington luminosity, and the root mean square (rms) variability as a function of the non-thermal to total lum...

STUDY DESIGN This is a bioinformatic study designed to investigate the time-course expression changes of microRNAs (miRNAs) after spinal cord injury (SCI). OBJECTIVE To investigate the mechanism of SCI self-repair at miRNAs level and target genes level. SUMMARY OF BACKGROUND DATA SCI results in loss of sensory and locomotor function, and SCI self-repair might provide clinical therapies; how...

Honeycomb structure has frequently been observed in two-dimensional (2D) materials. CuAu the buckled honeycomb (BHC) was synthesized recently, which is a case of 2D intermetallic compound. Here, dynamical stability $AX$ BHC structure, where $A=\mathrm{Cu}$, Ag, and Au, $X$ metallic element Periodic Table, systematically studied by calculating phonon dispersions from first-principles. Among 135 ...
