Fungal endophytes were isolated from the leaves, stems and roots of two widely used medicinal plantsviz.,Andrographis paniculata (Burm. f.) Wall. exNeesand Centella asiatica (L.)Urban. A total 28 endophytic fungi identified based on morphological molecular analyses. The were: Aspergillus flavus (Link), A. fumigatus (Fresen.), niger (Tiegh), terreus (Thom), Cladosporium sp., Colletotrichum Curvu...

Total and average distance are not only interesting invariants of graphs in their own right but are also used for studying properties or classifying graphical systems that depend on the number of edges traversed. Recent examples include studies of computer networks [3] and the use of graphical invariants to partially classify the structure of molecules [1]. There have been a number of conjectur...

A multi-agent model of social and environmental complexity of deforestation was developed for the Caparo Forest Reserve, Venezuela. It includes three types of agents: settlers, government, and lumber concessionaires. Settlers represent people of limited economic resources that deforest and occupy reserve land to grow crops and eventually claim property rights of this land. Their agricultural pr...

This paper discusses a simulation theory with learning agents which is serving as a formal specification to guide the development of GALATEA, a multi-agent simulation platform. We have extended an existing simulation language: GLIDER, with abstractions to model systems where autonomous entities (agents) perceive and act upon their environments. We are now applying it to the study of multi-agent...

Farmed parklands of the Central Plateau, Burkina Faso, integrate native woody vegetation with managed cropland. However, sapling survival in is increasingly threatened. This study characterized abundance along a 2.7 km long transect Doulou Basin, Boulkiemdé Province, West Region, to assess changes composition since 1984. In addition, householder survey was conducted gain insight into tree uses ...

Fruit spot disease of Phyllanthus emblica L. is one theproblems, which reduce the quality fruits at pre-harvest period. Fungal pathogen was isolated using tissue planting methods during November 2016 to December 2017. The fungus, Thielaviopsis paradoxa identified both morphological and molecular characterization based on internal transcribe spacer (ITS) region ribosomal DNA (rDNA). Mycelial gro...
