Cell and tissue cultures of Catharanthus roseus: A literature survey

Abstract: The literature concerning the regulation and the biosynthesis of secondary metabolites in cell and tissue cultures of Catharanthus roseus is reviewed. The aim of this review is to summarise the progress achieved since the previous review of this subject from 1988 to December 1993. Several factors influencing the production of indole alkaloids are discussed. Special attention is given to large-scale cultivation methods. Some economic considerations on the production of ajmalicine are also discussed.

Agency theory: Review of Theory and Evidence on Problems and Perspectives:

Abstract: This article intends to review the theoretical aspects and empirical evidences made on agency theory It is aimed to explore the main ideas, perspectives, problems and issues related to the agency theory through a literature survey It discusses the theoretical aspects of agency theory and the various concepts and issues related to it and documents empirical evidences on the mechanisms that diminish the agency cost The conflict of interest and agency cost arises due to the separation of ownership from control, different risk preferences, information asymmetry and moral hazards The literatures have cited many solutions like strong ownership control, managerial ownership, independent board members and different committees can be useful in controlling the agency conflict and its cost This literature survey will enlighten the practitioners and researchers in understanding, analysing the agency problem and will be helpful in mitigating the agency problem

Heavy metals removal from aqueous environments by electrocoagulation process- a systematic review.

Abstract: Heavy metals pollution has become a more serious environmental problem in the last several decades as a result releasing toxic materials into the environment. Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical processes were used for the treatment of domestic, industrial and agricultural effluents. The commonly used conventional biological treatments processes are not only time consuming but also need large operational area. Accordingly, it seems that these methods are not cost-effective for effluent containing toxic elements. Advanced oxidation techniques result in high treatment cost and are generally used to obtain high purity grade water. The chemical coagulation technique is slow and generates large amount of sludge. Electrocoagulation is an electrochemical technique with many applications. This process has recently attracted attention as a potential technique for treating industrial wastewater due to its versatility and environmental compatibility. This process has been applied for the treatment of many kinds of wastewater such as landfill leachate, restaurant, carwash, slaughterhouse, textile, laundry, tannery, petroleum refinery wastewater and for removal of bacteria, arsenic, fluoride, pesticides and heavy metals from aqueous environments. The objective of the present manuscript is to review the potential of electrocoagulation process for the treatment of domestic, industrial and agricultural effluents, especially removal of heavy metals from aqueous environments. About 100 published studies (1977–2016) are reviewed in this paper. It is evident from the literature survey articles that electrocoagulation are the most frequently studied for the treatment of heavy metal wastewater.
