Authors: Wisniak, Jaime
Abstract: The understanding and quantification of the phenomenon of heat radiation has gone through many phases, parallel to the interpretation of the concept of heat.

Authors: Kumar, B V Suresh; Byrappa, K; Rai, K M Lokanatha; Anand, S; Rao, R V
Abstract: AlPO<sub>4</sub>-11
was used as catalyst for the synthesis of bisphenol-A by Friedel-Crafts
condensation of acetone with phenol in presence of carbon tetrachloride and
synthesis of cinnamic acid by Knovenagel condensation of aromatic aldehydes
with malonic acid in presence of ethyl alcohol.

Authors: Parekh, Dimple C; Patel, Jignesh B; Sudhakar, Padmaja; Koshy, V J
Abstract: <span style="font-size:14.0pt;font-family:" times="" new="" roman";color:black;mso-bidi-font-weight:="" bold"="" lang="EN-IN">Removal of heavy metals like Cu, Cd, Pb from aqueous solution was studied
using mango seeds powder. Study was carried out in batch technique as a
function of contact time, metal ion concentration and <i>p</i>H of the
solution. The sorption process follows Freundlich sorption isotherm. Maximum
sorption was observed at acidic <i>p</i>H itself. The method is applied to
various synthetic solutions.

Authors: Khobragade, C N; Chandel, S G
Abstract: <span style="font-size:14.0pt;font-family:" times="" new="" roman";color:black;mso-bidi-font-weight:="" bold"="" lang="EN-IN">Invertase is an intracellular hydrolytic enzyme widely used in the
inversion of sucrose into glucose and fructose. Both glucose and fructose are
the primary compounds used as sweeteners in the food processing industries. In
the present investigation invertase was immobilized in sodium alginate gel by
entrapment method and the catalytic activity of immobilized enzyme was compared
with the activity of native enzyme at variable <i>p</i>H and temperatures.
Experimental findings revealed that for native enzyme optimum activity was at <i>p</i>H
4.2 and at temperature 30°C, while for immobilized enzyme it was observed at <i>p</i>H
4.8 and at temperature 50°C. Kinetic parameters <i>K</i><sub>m</sub><i> </i>and
<i>V</i><sub>max</sub> as well as catalytic efficiency of invertase was also
determined for both the native and immobilized enzyme.
