Development of Bursaphelenchus xylophilus Populations in Wood Chips with Different Moisture Contents.
Bags of Pinus strobus wood chips with moisture contents of 38, 92, 164, and 217% (oven dry weight) were inoculated with Bursaphelenchus xylophilus and incubated at 30 C in order to determine the effect of wood moisture on nematode population development. Nematodes were extracted after 2, 4, 8, and 12 weeks. Population levels were greatest in wood chips with a moisture content of 38% and decreas...
متن کاملeffects of initial moisture content on wood decay at different levels of gaseous oxygen concentrations
the influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. three fungi, coriolus versicolor (c. versicolor) a white rot, coniophora puteana (c. puteana) a brown rot, and chaetomium globosum (c. globosum) a soft rot, were chosen. the mycelia of the fungi were inoculated in to mini blocks of fagus sylvatica (beech) and pinus sy...
متن کاملPrediction of Equilibrium Moisture Contents of Black Grape Seeds (Siah Sardasht cultivar) at Various Temperatures and Relative Humidity: Hhelf-Life Criteria
Background and Objectives: Food wastes are sometimes valuable; of which, seeds are significantly important. Grape seeds, as byproduct of grape processing, contain valuable substances for the production of advanced oils as well as feeds. Therefore, the major aim of this study was to assess moisture sorption isotherms of black grape seeds at various conditions. Materials and Methods: Moisture so...
متن کاملRheological Behavior of Hdpe-wood Flour Composites with Different Wood Contents
Rheological behavior of high-density polyethylene (HDPE)-wood flour composites with different wood contents was examined using steady shear sweep, oscillatory frequency sweep, creep test, and stress relaxation test. The samples were prepared using a melt compounding method in a twin-screw extruder. The results showed that the yield stress did not appear for the composites prepared under the pro...
متن کاملEquilibrium Theory of the Kaolinite-water System at Low Moisture Contents, with Some Remarks concerning Adsorption Hysteresis
A MICROSCOPIC theory of the kaol ini te-water system is presented, based upon the assumption t ha t the clay-water interaction may be envisioned as par t ly hydrat ion of the exchangeable cations and par t ly adsorption by the oxygen and hydroxyl surfaces. The theory t reats exchangeable cation hydrat ion quantum-mechanically as an ion-dipole phenomenon and considers water adsorption by the min...
