Estimates of dead and down woody material (DWM) biomass are important for nutrient cycling, wildlife habitat assessment, fire effects climate change science. Most methods used to sample initially assess volume then estimates wood density convert biomass. To initial decomposition rate, this study examined in situ lodgepole pine logs at the Tenderfoot Creek Experimental Forest (TCEF), central Mon...
This paper seeks to answer the question of whether magnitude vibrations affecting whole body harvester operator (WBV) that are generated by boom is affected size processed trunk volume, specify closer, WBVs during forest logging, and localise these in individual partial operations. For purposes, production process, i.e., was divided into six operations (Searching; Felling; Processing; Unproduct...

selective desulfurization of thiocarbonyls to carbonyls thioacetalization of aldehydes and ketones a useful reagent system for the dethioacetalization reactions
The most important factor to ensure forest regrowth strongly relies on minimizing damage as well maintaining an adequate quantity and quality of residual stands. Currently, the Malaysian concessions are applying Selective Management System (SMS). SMS had been introduced about 40 years ago various studies discovered that it contributes a negative impact forest. Thus, revision adoption appropriat...
The response of forests and terrestrial ecosystems to disturbance is an important process in the global carbon cycle in the context of a changing climate. This study focuses on the effect of selective felling (thinning) at a managed forest site. Previous statistical analyses of eddy covariance data at the study site had found that disturbance from thinning resulted in no significant change to n...
