The theoretical and analyzed data incorporated in this article are related to the recently published research article entitled "Thermal degradation behaviour of nanoamphiphilic chitosan dispersed poly (lactic acid) bionanocomposite films" (http://ift.tt/2gfTztD) (A.K. Pal, V. Katiyar, 2016) [1]. Supplementary information and data (both raw and analyzed) are related to thermal degradation kinetics and explains various model fitting and is conversional methods, which are used in this research work to enhance the knowledge about degradation behaviour of PLA/CH-g-OLLA bionanocomposite system. Non-isothermal degradation kinetics of such polymeric system was proposed using Kissinger, Kissinger–Akahira–Sunose, Flynn–Wall–Ozawa and Augis and Bennett models to estimate the activation energies (Ea) and R² values.

Flow cytometric data analysis of circulating progenitor cell stability

We performed a quality control assessment of the stability of circulating blood progenitor cells in blood samples stored at 4°C, to determine the time period during which blood samples can be analyzed and yield consistent data for progenitor cell content. Healthy volunteers (n=6) were recruited and underwent phlebotomy, and blood was stored in EDTA tubes at 4°C. Flow cytometry was performed to quantitate progenitor cell subsets at 0–4h, 24h, and 48h post phlebotomy. All processed samples were fixed with 1% Paraformaldehyde and 1,000,000 total data events were collected. We found no significant differences in PC data for both CD34+ (P=0.68 for one-way ANOVA) and CD34+/CD133+ (P=0.74 for one-way ANOVA).

Biblical commentary in the Old Hispanic liturgy: a Passiontide case study

Old Hispanic (Mozarabic) chant was sung on the Iberian Peninsula until the 11th century. Although thousands of notated chants survive, for the whole liturgical year, almost all of them are in unpitched notation. The meaning of this music is best accessed first through its texts, reading them in the light of the other liturgical elements that surrounded them, and through the traditions of biblical exegesis that were known on the Iberian Peninsula. This better positions us to analyse the notation and how it might relate to the text. Through this method, as we show in a case study of one simple Lenten Office, we can begin to form a picture of what the chant texts meant to participants in the liturgy and how the melodies helped to convey this meaning.
