Quinoa stalks were used as a source of hemicellulose for XOs production and further as prebiotic source for probiotic bacteria. Three methods for extraction of hemicellulose were used, of which alkaline extraction (NaOH [0.5 M]) was the optimum method. This methodology allowed the establishment of a sequential extraction platform, including saponins obtention via PHWE, hemicellulose via alkaline e

In order to evaluate the traditional morphological characters commonly used to distinguish the taxonomically problematic species of Legousia, we carried out a morphometric study with univariate analysis, principal component analysis (PCA), discriminant analysis (DA) and cluster analysis (UPGMA). The analyses were based on data from 436 individuals on 207 herbarium specimens from 18 countries in EuIn order to evaluate the traditional morphological characters commonly used to distinguish the taxonomically problematic species of Legousia, we carried out a morphometric study with univariate analysis, principal component analysis (PCA), discriminant analysis (DA) and cluster analysis (UPGMA).

The present paper shows a green method for the formation of polypyrrole by two different MIUG 12p and MIUG 4.88 strains of Streptomyces spp. bacteria. According to our knowledge, such method has never been proposed before for pyrrole oxidation. For this experiment pyrrole monomer was added into bacterial medium after 6 days of incubation and after 4 days polypyrrole (PPy) based 10–25 μm microspher

In this work sol-gel process for preparation of the uniform hybrid silica-3-aminopropyltriethoxysilane (APTES) coatings on glass surface is presented from mechanistic point of view. The suggested synthetic approach is straightforward, scalable and provides the means to tune the amount of amino groups on the surface simply by changing concentration of APTES in the initial sol. Deposition rate of di

Infrared spectra of gaseous, liquid, and matrix-isolated samples of newly synthesized 1,1-dimethyl-2-oxy-1-silacyclohexane were recorded. Raman spectra of 1,1-dimethyl-2-oxy-1-silacyclohexane in liquid and solid states were obtained in the temperature range from 170 to 340 K. Ab initio HF and DFT B3LYP calculations were performed in order to determine the possible conformations of 1,1-dimethyl-2-o

Raman spectra of liquid, and infrared spectra of gaseous as well as matrix isolated 1,1,2,2-tetrachloro-1,3-disilacyclopentane were recorded and analyzed with the aid of DFT calculations. Complete assignment of the experimental vibrational spectral bands is made. Experimental results and DFT calculations confirm that 1,1,2,2-tetrachloro-1,3-disilacyclopentane exists as single twist conformer in ga

Fourier transform infrared (FT-IR) spectroscopy was applied to characterize the extracellular matrix (ECM) of kidney tumor tissue and normal kidney tissue. Freshly resected tissue samples from 31 patients were pressed on a CaF2 substrate. FT-IR spectra obtained from ECM of tumor tissue exhibit stronger absorption bands in the spectral region from 1000 to 1200 cm−1 and around 1750 cm−1 than those o

Distribution of chemical components in the mixed oxalatic, phosphatic and uratic urinary stones was analysed by means of infrared microspectroscopy. The specular reflection from the surface of the cross-sectioned stones was used for the infrared spectroscopic imaging. It was found that the reflection spectra consist from specular and diffuse reflection components and the former one exhibit Reststr

The silver nanoparticle colloid was used to obtain surface enhanced Raman spectra of Listeria monocytogenes, Salmonela enterica, and Esherichia coli bacteria. The SERS spectra were captured using for excitation the near-infrared (1064 nm) laser radiation with reduced intensity, which ensured the prevention of the fluorescence background as well as photo- and thermal decomposition of the samples. I

Infrared spectra of propanoic acid isolated in the neon and argon matrixes were obtained and studied with the aid of the DFT calculations. The geometric structures of the cyclic and open dimers of PA were elucidated. The calculations predict that among various types of the open dimers only one type with additional hydrogen bond between oxygen of hydroxyl group of a monomer and hydrogen of hydroxyl

Infrared spectra of matrix isolated formic, acetic, propionic, and butyric acids mixed with water were obtained. Combining experimental data and theoretical calculations we were able to assign spectral bands arising due to formation of 1:1 complex between water and title acids. The structure of such complexes was elucidated from theoretical and spectral data for the first time. Alternating decreas

PurposeTo describe demographic and diagnostic profiles in a national cohort of older people with intellectual disability (ID) who were prescribed antipsychotics.MethodsUsing national registers, we identified people with ID who were 55 + years in 2012 (n = 7936), as well as a subcohort with complete information on demographic factors (sex, year of birth, severity of ID, presence of behavior impairm

In this paper we describe present work on multimodal prosody bymeans of simultaneous recordings of articulation and head movements. Earlierwork has explored patterning, usage and machine-learning based detection offocal pitch accents, head beats and eyebrow beats through audiovisual recordings.Kinematic data obtained through articulography allows for more comparableand accurate measurements, as we
