Carbonic Anhydrase, Photosynthesis, and Seed Yield in Mustard Plants Treated with Phytohormones

Abstract: The leaves of 30-d-old plants of Brassica juncea Czern & Coss cv. Varuna were sprayed with 10−6 M aqueous solutions of indole-3-yl-acetic acid (IAA), gibberellic acid (GA3), kinetin (KIN), and abscisic acid (ABA) or 10−8 M of 28-homobrassinolide (HBR). All the phytohormones, except ABA, improved the vegetative growth and seed yield at harvest, compared with those sprayed with deionised water (control). HBR was most prominent in its effect, generating 32, 30, 36, 70, 25, and 29 % higher values for dry mass, chlorophyll content, carbonic anhydrase (E.C. 4.2.1.1) activity, and net photosynthetic rate in 60-d-old plants, pods per plant, and seed yield at harvest, over the control, respectively. The order of response to various hormones was HBR > GA3 > IAA > KIN > control > ABA.

Prioritising the practices of total quality management: An analytic hierarchy process analysis for the service industries

Abstract: Total quality management (TQM) is a major business strategy which employs a set of principles and practices to achieve sustainable competitive advantage in the service industry. This research aims to categorise TQM practices and examine its relative importance for better implementation in service industries. The relative importance and ranking of TQM practices in service industries was done through a literature review, discussion with experts, and the analytic hierarchy process (AHP) approach. In all, 17 TQM practices were identified and further divided into three factor categories. Then their prioritisation was done using AHP approach to assign the relative importance of these 17 TQM practices in service industries. The results will help service industry managers to work upon them based on their relative importance to improve their TQM performance. Finally, limitations, managerial implications, and scope of future study are presented at the end.

Medium-Voltage Drives: Challenges and existing technology

Abstract: This article presents an overview of state-of-art solutions, advances, and design and research trends in medium-voltage (MV) drive technologies-and also discusses the challenges and requirements associated with the use of such drives. The choice and deployment of MV drives in industries are associated with numerous requirements related to the front-end converter (grid side) and inverter (machine side). The focus is on solutions that present high efficiency; low price, size, and weight; minimum harmonic distortion; reduction in dv/dt; mitigation of common-mode (CM) voltage; avoiding torsional vibration; transformerless solutions; fault detection capability; and condition monitoring.

Hydrolysis of milk/whey lactose by β galactosidase: A comparative study of stirred batch process and packed bed reactor prepared with calcium alginate entrapped enzyme

Abstract: Calcium alginate entrapped β galactosidase preparations were used for the hydrolysis of lactose from solution, milk and whey in batch processes as well as in continuous packed bed columns. The efficiency of columns, containing calcium alginate entrapped soluble and crosslinked concanavalin A complex of β galactosidase was examined at various flow rates at room temperature 32 °C, for the continuous hydrolysis of 0.1 M lactose for over 2 months. From the kinetic study the Michaelis constant ( K m ) were found to be 2.51 mM and 5.18 mM for the free and immobilized β galactosidase, respectively. The V max for the soluble enzyme and immobilized preparation was 4.8 × 10 −4 mol/min and 4.2 × 10 −4 mol/min, respectively. Furthermore, we found that entrapped crosslinked Con A–β galactosidase was more efficient in the hydrolysis of lactose present in milk (77%) and whey (86%) in batch processes as compared to the entrapped soluble β galactosidase.
