The research was based on a pot experiment in which the impact of increasing Cd, Zn and Pb doses content available trace elements soil compared. Seven series trials were designed: 1 (Cd), 2 (Pb), 3 (Zn), 4 (Cd + Pb), 5 Zn), 6 (Pb 7 Zn). Aside from control one (without metals), three levels contamination considered within each series. Mobile forms (Cd, Pb, Zn, Fe, Mn, Cu, Ni, Co, Cr) determined,...

Poly(ester-carbonate) copolymers were synthesized through triethylborane (TEB)-activated, one-pot copolymerization of epoxides with anhydrides (AH) and CO₂. Depending upon the feeding ratio AH to epoxides, poly(ester-carbonate) random tapered ester structures could be derived due much higher reactivity toward growing oxanions compared Anhydrides like succinic anhydride (SA) phthalic (PA) when t...

Hexagonal boron nitride (h-BN) is one promising material class for applications in DUV optoelectronics due to the layered structure and ultra-wide bandgap. The synthesis of h-BN with smooth surface morphology high quality on dielectric substrates key construct efficient functional devices thereon. In this study, we reported wafer-scale c-plane sapphire by metal organic chemical vapor deposition...

Bends in nucleic acid helices can be quantified in a transient electric birefringence (TEB) experiment from the ratio of the terminal decay times of the bent molecule and its fully duplex counterpart (T-ratio method). The apparent bend angles can be extracted from the experimental T-ratios through the application of static (equilibrium-ensemble) hydrodynamic models; however, such models do not ...

Secondary and tertiary structures of tRNAs are remarkably preserved from bacteria to humans, the notable exception being the mitochondrial (m) tRNAs of metazoans, which often deviate substantially from the canonical cloverleaf (secondary) or 'L'-shaped (tertiary) structure. Many metazoan mtRNAs lack either the TpsiC (T) or dihydrouridine (D) loops of the canonical cloverleaf, which are known to...

Previous investigation demonstrated that feeding a 10% flaxseed (10F) diet during pregnancy and lactation enhanced the differentiation of highly proliferative terminal end bud (TEB) structures of rat mammary gland into less proliferative alveolar buds and lobules. From this study, it was hypothesized that the lignan component in flaxseed mediated the observed effects. Because mammary glands wit...

Suomi NPP (National Polar-orbiting Partnership) satellite (http://npp.gsfc.nasa.gov/viirs.html) began to daily collect global data following its successful launch on October 28, 2011. The Visible Infrared Imaging Radiometer Suite (VIIRS) is a key NPP sensor. Similar to the design of the OLS, SeaWiFS and MODIS instruments, VIIRS has on-board calibration components including a solar diffuser (SD)...

To compare the different effects of implanting sensory nerve tracts or blood vessel on the osteogenesis, vascularization, and neurotization of the tissue-engineered bone in vivo, we constructed the tissue engineered bone and implanted the sensory nerve tracts (group SN), blood vessel (group VB), or nothing (group Blank) to the side channel of the bone graft to repair the femur defect in the rab...

Monolayer epitaxial graphene (EG), grown on the Si face of SiC, is an advantageous material for a variety of electronic and optical applications. EG forms as a single crystal over millimeter-scale areas and consequently, the large scale single crystal can be utilized as a template for growth of other materials. In this work, we present the use of EG as a template to form millimeter-scale amorph...
