This work investigated the ironwood used to construct a gambang, which is traditional musical instrument. A gambang constructed from wooden bar with similar thickness and width but different length. The sound established frequencies were compared equal tempered scale. peak differed intended pitch partials not always harmonic. only classified 4 octaves. audio classification of was based on signa...

The impacts of white-rot fungi on altering wood chemistry have been studied mostly in vitro. However, in vivo approaches may enable better assessment of the nature of interactions between saprotrophic fungi and host tree in nature. Hence, decayed and sound wood samples were collected from a naturally infected tree (Carpinus betulus L.). Fruiting bodies of the white rot fungus Trametes versicolo...

ABSTRACT Aspergillus spp. in section Flavi were frequently associated with desert tree legumes in uncultivated areas of the Sonoran Desert. Of 270 samples of debris and fruits of mesquite (Prosopis spp.), ironwood (Olneya tesota), acacia (Acacia spp.), and palo verde (Cercidium and Parkinsonia spp.), 87% were positive for A. flavus (S and L strains) and A. tamarii. A. flavus was the most common...

Abstract The study determined the similarities and differences between fuel properties of different types biomass (triticale oat straw; bark: oak, alder, hornbeam, pine) biochar (municipal waste biochar, composting pellet Fluid’s biochar). Bulk actual densities moisture contents, ash amounts, elemental composition (C, H, N) were determined, calorific value, heat combustion porosity substances s...

Understanding population dynamics is vital in amphibian conservation. To compare demography and movements, we conducted a capture-recapture study over three spring seasons two populations of Salamandra salamandra the Vienna Woods. The sites differ topography, vegetation, type breeding waters. Population density beech forest traversed by stream was more than twice as high an oak-hornbeam with te...
