ROSA is an e-learning system, which enables the management of Learning Objects (LOs). However, since ROSA is a centralized system, it does not provide a complete integration of LOs created in local ROSAs of other institutions. This paper presents the evolution of ROSA into a peer-to-peer (P2P) system the ROSA P2P, and describes the integration process of LOs in this environment. It provides the...

the mycorrhizal fungi are the most important micro-organism among the soil micro flora which via genetical, physiological and ecological changes lead to more yield in symbiotic plants.  the piriformospora indica sav. verma, aj. varma, rexer, g. kost & p. franken 1998, is one of well known endomycorrhizal fungus with different beneficial effects on diverse monocots (poaceae) and dicots (brassica...

Objective: This is to evaluate the effect Mangifera indica effects on the liver. The fruit of Mangifera indica is a major source of food for man and animal. The leaf, root and stem bark are widely used for medicines. Mangifera indica is used medicinally to treat ailments such as asthma, cough, diarrhea, dysentery, leucorrhoea, jaundice, pains, malaria, diabetes, asthma, infertility, lupus, pros...

Pathogenic effect of an indigenous entomopathogenic nematode, Heterorhabditis indica and commercial biopesticides of three fungal pathogens (M. anisopliae, B. bassiana and T. viride), one antagonistic bacteria (P. fluorescence), and two neem based biopesticides (Neem and Nimor) were tested on the Greater wax moth, Galleria mellonella larva under laboratory condition. The efficacy of the biopest...

Drugs from natural sources are used for treating various diseases since the ancient times. From the literature it is clear that various type of pharmacological and biological activities are associated with Azadirachta indica. The leave oil of A. indica is known to have good antimicrobial potential. The oil of A. indica leaves, was tested against the different infectious microorganisms [Gram pos...

Objective: The antiulcer activity of various extracts of Hibiscus rosa sinensis leaves was evaluated in pyloric ligation induced gastric ulcer in albino rats. Method: The leaves extracts were prepared by cold maceration process with petroleum ether, alcohol and water separately. Results: Oral administration of aqueous and alcohol extracts (200 and 400 mg/kg) of Hibiscus rosa sinensis leaves wer...

Understanding linkage block size and molecular mechanisms of recombination suppression is important for plant breeding. Previously large linkage blocks ranging from 14 megabases to 27 megabases were observed around the rice blast resistance gene Pi-ta in rice cultivars and backcross progeny involving an indica and japonica cross. In the present study, the same linkage block was further examined...

A glutinous texture of endosperm is one of the important traits of rice (Oyza sativa L.). Northern Laos is known as a center of glutinous rice diversity. We genotyped INDEL, SSR and SNP markers in a sample of 297 rice landraces collected in northern Laos. These glutinous varieties were confirmed to share a loss-of-function mutation in Granule bound starch synthase I (Wx). INDEL markers revealed...

Azadirachta indica leaves indicated the presence of active principles with proven antioxidants, antiinflammatory, immunomodulatory, free radical scavenging and healing properties. In the present study we evaluated the healing effects of 50% ethanol extract of dried leaves of Azadirachta indica on trinitrobenzene sulfonic acid-induced colitis in rats. Azadirachta indica extract (500 mg/kg) was a...

Pavetta indica Linn is used in the traditional medicine for many diseases.In the present study, the diuretic activity of Petroleum ether and Methanol extract of leaves of Pavetta indica was studied and the activity was compared with furosemide as standard.All the extracts exhibited significant diuretic activity as evidenced by increased total urine volume and the urine concentration of Na , K a...
