In the wildtype, and in constructs downregulated in PAL, 4CL, and C3H, the fungal pretreatment resulted in substantial improvements in sugar yields, up to 2.4-fold increase in glucose yield and 6-fold increase in xylose yield after enzymatic hydrolysis compared to the unpretreated control.

Understanding these relationships allows watershed managers and regulators to prioritize river restoration and contaminated site remediation projects. In this dendrogeomorphic study, changes in the anatomy of tree roots exposed between 1 and 31 years were used to estimate the average annual erosion rates of riverbank sediments on a large river in Michigan, USA. Exposed root samples from diffuse and ring‐porous hardwoods, together with buried ones as controls, were analyzed. Differences in the arrangement, size and frequency of vessels, fiber diameter, cell wall thickness, growth ring width, and scarring between the exposed and the buried samples were used to identify the first year of root exposure. Results of the regression analysis between the average annual erosion rate and the Bank Erosion Hazard Index (BEHI) indicated that the more recently exposed roots (less than 7 years in this study) explained more of the variance (R2 = 0.67) than when all samples were included (R2 = 0.38). Although the average erosion rates for long periods can be accurately determined from the dating of exposed tree roots, attempts to relate these rates using the BEHI for longer periods are less successful, as BEHI values can vary considerably over time as the riverbank erodes. Consequently, when using exposed tree roots to develop regression equations and erosion rate curves for the estimation of erosion rates based on BEHI scores, it is necessary to use roots that were recently exposed.

In Europe, the exterior finish uses the External Thermal Insulation Composite System attached to a gypsum board sheathing. This study was performed to compare the hygrothermal performance of American and European walls by using a finite-element model. Analysis showed that the European wall has better thermal performance mainly because of the heat-insulating ability of the expanded polysterene (EPS) layer. But when the EPS was reduced to the same thickness as the siding used in American construction, the thermal performance of the European wall did not fare any better than the American structure. The resistance of the European wall to moisture damage was also better than the American walls. One reason for this is the high diffusion resistance of the EPS. But this same high diffusion resistance works to the detriment of an Exterior Insulation Finish System (EIFS) wall if water is able to infiltrate the structure. When water leakage is present, the water content of the OSB in the EIFS wall reaches levels that make it vulnerable to mold growth and fungal decay.}, journal={ENERGY AND BUILDINGS}, author={Pasztory, Zoltan and Peralta, Perry N. and Molnar, Sandor and Peszlen, Ilona}, year={2012}, month={Jun}, pages={142–147} } @article{csoka_hoeger_rojas_peszlen_pawlak_peralta_2012, title={Piezoelectric Effect of Cellulose Nanocrystals Thin Films}, volume={1}, ISSN={2161-1653 2161-1653}, url={http://dx.doi.org/10.1021/mz300234a}, DOI={10.1021/mz300234a}, abstractNote={Ultrathin films of aligned cellulose nanocrystals (CNCs) were assembled on mica supports by using electric field-assisted shear.

The results show that. compared to wood, giant-timber bamboo exhibits less hygroscopicity and greater hysteresis. The differential heat of sorption. Q was found to be an exponential function of fractional moisture content, m, and decreased somewhat with increasing temperature. The relation Q s = (Q s ) o exp(-B 1 m) was considered to he reasonably adequate, but a better fit was provided by the equation Q s = A 2 + B 2 m + C 2 exp(-D 2 m) so that it was used in the calculation of the heat of wetting, W, and the integral heat of sorption, (W o - W). The differential heat of sorption at ovendry condition fell within the range observed for wood and other lignocellulosic material, The free energy, G., and the entropy, S., of sorbed water were in close agreement with those observed for wood, reconfirming the theory that definite enthalpy, free energy, and entropy changes accompany the sorption of water by lignocellulosic materials.}, number={2}, journal={HOLZFORSCHUNG}, author={Peralta, PN and Bangi, AP and Lee, AWC}, year={1997}, pages={177–182} } @article{peralta_1996, title={Moisture sorption hysteresis and the independent-domain theory: The moisture distribution function}, volume={28}, number={4}, journal={Wood and Fiber Science}, author={Peralta, P.
