    Changes in Phosphorus Fractions and Phytase Activity of Rice Seeds during Germination (1971)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 25 (1971), S. 0 
    Details
    ISSN: 1399-3054

    Topics: Biology
    Notes: The present experiment provides information on the phosphorus compounds in rice seeds and elucidates the changes they undergo during germination. In ungerminated seeds, the bulk of total-P appears in phytin (about 76 per cent). It is then dephosphorylated in course of germination with a simultaneous accumulation of large amounts of inorganic-P. Lipid-P increases very rapidly from 0 to 24 hours. The increase up to 72 hours is gradual, after which it drops at 96 hours and again rises to a maximum after 120 hours. The ester-P and RNA-P, fractions increase in concentration with time of germination (except 120 hours). Protein-P begins to fall after 48 hours, while DNA-P remains more or less constant throughout the experiment.The two pH optima recorded for phytase activity at 4.0 and 9.0, suggests that there exist two phytases, one acidic and the other alkaline. Both behave similarly during germination with a continuous increase throughout the course of the experiment. The enzyme with an optimal pH at 4 hydrolyses phytin more actively than the other with the pH optimum at 9.0. Phytase shows maximum activity at a stage when most of the phytin has disappeared; the metabolic significance is uncertain.

    Rhamnose Bound Indole-3-Acetic Acid in the Floral Parts of Peltophorum ferrugineum (1974)

    Notes: The presence of rhamnose bound indole-3-acetic acid (IAA) was reported from acetone extract of anthers and carpels of the flowers of Peltophorum ferrugineum. Hydrolysis of the sugar ester gave IAA and rhamnose. Identification of IAA was based on physical measurements supported by bioassay. Bound and free IAA were not detected in petals, seeds and seed coats.

    Metabolic Changes in Developing Rice Seeds (1971)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 24 (1971), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Metabolic changes in developing rice seeds were studied with respect to respiration, carbohydrate and nitrogen fractions, nucleic acids and hydrolytic enzymes, viz. α-amylase, adenosine triphosphatase (ATPase) and phytase. — Respiration rate was maximum after 12 days from the date of pollination and became feeble afterwards with the fall in the moisture content of the maturing seeds. In the early stage, there was a preponderance of reducing sugars which were replaced later by nonreducing forms. Dry matter accumulation was mainly due to the steady rise in starch content. There was a gradual accumulation of protein nitrogen throughout the experiment, the rate being highest between 12–16 days. RNA content increased steadily till the seeds became mature, while DNA formed rapidly during the first 20 days and was maintained at the same level thereafter. —α-Amylase activity increased up to 20 days and declined sharply afterwards. The peak activities of ATPase and phytase were recorded at 32 and 24 days after pollination, respectively.

    Lead content of indian tea (1973)
    Springer
    Bulletin of environmental contamination and toxicology 9 (1973), S. 124-128

    ISSN: 1432-0800

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Medicine
    Notes: Summary A random survey was conducted to determine lead content in Indian tea and its decoctions. Lead content of various samples of tea was found to be between 0.4 to 1.6 ppm and in decoctions it was between 0. 002–0. 012 mg/liter. The effect of temperature and pH was also studied and it was found that larger amount of lead was leached out in the decoctions at low pH and at high temperature.

    Notes: Abstract The performance of a pressure swing adsorption (PSA) process for production of high purity hydrogen from a binary methane-hydrogen mixture is simulated using a detailed, adiabatic PSA model. An activated carbon is used for selective adsorption of methane over hydrogen. The effects of various independent process variables (feed gas pressure and composition, purge gas pressure and quantity, configuration of process steps) on the key dependent process variables (hydrogen recovery at high purity, hydrogen production capacity) are evaluated. It is demonstrated that many different combinations of PSA process steps, their operating conditions, and the feed gas conditions can be chosen to produce an identical product gas with different hydrogen recovery and productivity.

    Why Does the Linear Driving Force Model for Adsorption Kinetics Work? (2000)
    Springer
    Adsorption 6 (2000), S. 137-147 
    Details
    ISSN: 1572-8757
    Keywords: adsorption ; kinetics ; linear driving force model ; process design

    Notes: Abstract The Linear Driving Force (LDF) model for gas adsorption kinetics is frequently and successfully used for analysis of adsorption column dynamic data and for adsorptive process designs because it is simple, analytic, and physically consistent. Yet, there is a substantial difference in the characteristics of isothermal batch uptake curves on adsorbent particles by the LDF and the more rigorous Fickian Diffusion (FD) model. It is demonstrated by using simple model systems that the characteristics of the adsorption kinetics at the single pore or the adsorbent particle level are lost in (a) evaluating overall uptake on a heterogeneous porous solid, (b) calculating breakthrough curves from a packed adsorbent column, and (c) establishing the efficiency of separation by an adsorptive process due to repeated averaging of the base kinetic property. That is why the LDF model works in practice.
