Tropical regions receive the highest level of global solar ultraviolet (UV) radiation especially UV-B (280-320 nm). The average daily dose of the UV-B radiation in Madurai, South India (10°N) is 10 kJ m-2. This is approximately 50% more than the average daily UV-B radiation in many European countries. A field study was conducted using selective filters to(More)
The impacts of solar UV (280–400 nm) radiation on photosynthetic activities and polypeptide composition of thylakoids of cluster bean (Cyamopsis tetragonoloba L, UV-B sensitive) and black gram (Vigna mungo L., UV-B resistant) plants were compared. The activity of photosystem 1 and especially photosystem 2 increased in cluster bean while decreased in black(More)
The present study was undertaken to evaluate the anxiolytic activity of methanolic extract of Sapindus mukorossi Gaertn.(Sapindaceae). The anxiolytic activity was evaluated by Elevated plus maze, Y-maze, Hole-board, Actophotometer, and Marble-burying behavior models. The efficacy of the extract (200 and 400 mg/kg) was compared with the standard anxiolytic(More)
Intrusion detection has become a main part of network security due to the huge number of attacks which affects the computers. This is due to the extensive growth of internet connectivity and accessibility to information systems worldwide. To deal with this problem, in this paper a hybrid algorithm is proposed to integrate Modified Artificial Bee Colony(More)
The effect of low doses of UV-A (320–400 nm) and UV-B (280–320 nm) radiation on photosynthetic activities inPhaseolus mungo L. was investigated under field condition. Supplementation of UV-A enhanced the synthesis of chlorophyll and carotenoids than the UV-B supplemented plants. Significant increase was seen in the concentration of UV-B absorbing compounds(More)
The present study was undertaken to evaluate the antidiabetic activity of methanol extract of Flacourtia jangomas (lour) in streptozotocin induced diabetic rats. In this study, the acute and subacute anti hyperglycaemic effect of the two different doses (200 and 400 mg/kg b.w.p.o) of plant extracts were investigated. Fasting blood glucose level, body weight(More)
Security is becoming a critical part of organizational information systems and security of a computer system or network is compromised when an intrusion takes place. In the field of computer networks security, the detection of threats or attacks is nowadays a critical problem to solve. Intrusion Detection Systems (IDS) have become a standard component in(More)
With the widespread use of Internet, the possibilities of exposing confidential data to invaders or attackers increases. Intrusion Detection System (IDS) is used for detecting various intrusions in network environment and to prevent data from malicious attackers. In this paper, a combined algorithm based on Principal Component Analysis (PCA) and Core Vector(More)
The present work is to evaluate the anxiolytic activity of a hydroalcoholic extract of Tephrosia purpuria (L) Pers (HAETP) in mice using the elevated plus-maze (EPM), elevated zero-maze (EZM), Y-maze and hole-board models. Furthermore, the anxiolytic effects of HAETP were compared to a known active anxiolytic drug diazepam. The extract, administered orally,(More)
We investigated the effects of UV-A and UV-B enhanced radiation on plants ofPhaseolus mungo. Low doses caused varying responses in such growth and yield components as shoot and root lengths, leaf area, fresh mass and dry matter, pod numbers, and seed numbers and weights. Compared with the performances of the control plants, supplementation with UV-A(More)
