A model procedure has been developed for the rapid extraction of five bacteriocins (nisin, pediocin RS2, leucocin BC2, lactocin GI3, and enterocin CS1) from concentrated freeze-dried crude culture supernatants by adsorption onto acid or alkaline rice hull ash (RHA) or silicic acid (SA). Bacteriocins were adsorbed onto RHA or SA by a pH-dependent method and desorbed by decreasing the pH to 2.5 o...

We establish a general splitting formula for index bundles of families of Dirac type operators. Among the applications, our result provides a positive answer to a question of Bismut and Cheeger [BC2].

A series of new Cr5+xMo35?xW12Re35Ru13C20 high-entropy alloys (HEAs) have been synthesized and characterized by x-ray diffraction, scanning electron microscopy, electrical resistivity, magnetic susceptibility specific heat measurements. It is found that the HEAs adopt a noncentrosymmetric cubic ?-Mn type structure exhibit bulk superconductivity for 0 ? x 9. With increasing x, lattice parameter ...

A systematic study is presented on the superconductivity (sc) parameters of the ultrapure niobium used for the fabrication of the nine-cell 1.3 GHz cavities for the linear collider project TESLA. Cylindrical Nb samples have been subjected to the same surface treatments that are applied to the TESLA cavities: buffered chemical polishing (BCP), electrolytic polishing (EP), low-temperature bakeout...

Abstract Purpose Nitrification and denitrification in soil are key components of the global nitrogen cycle. This study was conducted to investigate effect biochar application on bacterial diversity. Methods Pot experiments were effects different biochar-based rates 0% (CK), 0.5% (BC1), 1.0% (BC2), 2.0% (BC3), 4.0% (BC4) nutrient community diversity composition. Results The results indicate that...

This paper discusses operators lowering or raising the degree but preserving the parameters of special orthogonal polynomials. Results for onevariable classical (q-)orthogonal polynomials are surveyed. For Jacobi polynomials associated with root system BC2 a new pair of lowering and raising operators is obtained.

BACKGROUND We previously selected a panel of 3 breast cancer biomarkers (BC1, BC2, and BC3) from serum samples collected at a single hospital based on their collective contribution to the optimal separation of breast cancer patients and noncancer controls by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The identities and general applicability of ...

Scouring around the bridge pier is a natural and complex phenomenon that results in failure. Failure of bridges have potential devastation public safety economic loss, which lead to political consequences environmental impacts. Therefore, it essential countermeasure scour pier. This paper studies effects four different airfoil-shaped collars (i.e., bc1 = 1.5b, bc2 2.0b, bc3 2.5b bc4 3.0b, where...

Miniature hyperspectral and thermal cameras onboard lightweight unmanned aerial vehicles (UAV) bring new opportunities for monitoring land surface variables at unprecedented fine spatial resolution with acceptable accuracy. This research applies imagery from a drone to quantify upland rice productivity water use efficiency (WUE) after biochar application in Costa Rica. The field flights were co...
