Micropropagation of four blueberry cultivars

open access: yesAgronomía Costarricense, 2015
Sharpblue, Woodard, Bonita and Delite cultivars were propagated from leaf explants. Leaf sections from in vitro singlenode explants were compared with those from plants in the field. The explants were placed in WPM medium supplemented with 1.5 mg.l-1 TDZ

The Effect of Lactic Acid in Association With Steam in Reducing Microorganisms in Soft Wheat

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Within the food industry, steam is an effective method of microbial reduction for a variety of products. Previous studies have shown that tempering soft wheat with organic acids, as well as steam application, can potentially reduce wheat's microbial load with minor changes in the functional properties of the flour ...

Physiological competition of brain phenylalanine accretion: Initial pharmacokinetic analyses of aminoisobutyric and methylaminoisobutyric acids in Pahenu2−/− mice

open access: yesMolecular Genetics and Metabolism Reports, 2015
Objective: Initial studies on the use of non-physiological amino acids (NPAAs) to block the accretion of Phe in the brain of Pahenu2−/− mice revealed that 2-aminoisobutyrate (AIB) and N-methyl-2-aminoisobutyrate (MAIB) were promising lead compounds whose

Reanalysis of pion pion phase shifts from K -> pi pi decays [PDF]

open access: yes, 2009
We re-investigate the impact of isospin violation for extracting the s-wave pion pion scattering phase shift difference delta_0(M_K) - delta_2(M_K) from K -> pi pi decays.

Experimental and theoretical study on the infrared spectroscopy of astrophysically relevant PAH derivatives 2- and 9-vinylanthracene

open access: yes, 2012
We propose to evaluate the contribution of polycyclic aromatic hydrocarbon molecules that carry side groups to the mid-infrared emission spectra. Within this framework, the IR absorption spectra of 2- and 9-vinylanthracene were measured in Ar matrices at

Characterizing maser polarization: effects of saturation, anisotropic pumping and hyperfine structure [PDF]

open access: yes, 2019
The polarization of masers contains information on the magnetic field strength and direction of the regions they occur in. Many maser polarization observations have been performed over the last 30 years.
