Steroidogenic organs such as adrenal gland and gonad are of vital importance in birds, as the adrenal gland regulates stress by modulating the levels of corticosterone, while gonads synthesize gonadal steroids that regulate breeding cycle. Cholesterol content in both adrenal and gonad reflect the physiological status of these organs for stress management and reproduction, respectively. Birds, being photosensitive, experience phototoxicity in the nature due to the rapid urbanization. If photic stress induced by constant dark (DD) and constant light (LL) influences steroidogenesis in terms of cholesterol content and total antioxidant status (TAS%) as a marker of stress was experimentally assessed in Indian spotted finch Lonchura punctulata along with measurement of peripheral corticosterone levels. DD was stressful and, hence, caused decrease of ovary / testis weight and increase of adrenal gland weight, while cholesterol content decreased significantly due to inhibition of steroidogenesis. LL stimulated gonadal function but caused decrease of cholesterol content suggesting active steroidogenesis. TAS% increased under DD and decreased under LL. The phototoxicity, whether in term of DD or LL, was stressful to Indian spotted finch as evident from increased adrenal gland weight and decreased cholesterol content that can be correlated with increased synthesis of corticosterone. It may be concluded that cholesterol content is an important marker of streroidogenic status, and extremes of photoperiod influence cholesterol content, corticosterone level and TAS%.Keywords

Fining frequent item set is a key issue in data mining; the Apriori algorithms use candidate itemsets to generate Frequent item set , but this approach is highly time-consuming because of self joining and prunining . To look for an algorithm that can avoid the generating of vast volume of candidate itemsets, DSIM (Data-Set Intersection Method) algorithm uses set intersection method to find the maximal frequent itemset.This process is performed by deleting items in infrequent 1-itemset and merging duplicate transaction repeatedly; the process is performed by generating intersections of transactions and deleting unneeded subsets recursively. This algorithm differs from all other methods which are used for discovering maximal frequent itemset.Keywords

The share of electronic resources in library subscriptions has been increasing over a period of time. Academic institutions worldwide spend significant amounts on electronic resources, including e-journals, databases, and eBooks. Global research indicates that the management of electronic resources is very complex, and the workflows associated with them differ from the workflow of print resources. Although electronic resources have been around for almost two decades, librarians are still trying to figure out the most effective way to handle them. The study suggests that many non-compatible stand-alone systems are used to manage electronic resources. Library Management Systems (LMS) and Library Services Platforms (LSPs) cannot manage electronic resource workflow. Electronic Resource Management Systems (ERMS) can be used to manage electronic resource workflow. However, cost is an important factor in not using commercial ERMS. This study examines the implementation of open-source ERMS CORAL in the Central Library, IIT Delhi. It discusses the steps involved in the implementation stages and the problems faced while implementing the system. It also discusses the features of CORAL. This study also finds improvements in electronic resource management after the implementation of ERMS CORAL. This study will be beneficial for those institutes that are looking for the implementation of CORAL.Keywords
