- This investigation has established the possibility of using Infra-density to determine the density of medium density fiber board (MDF). The statistical analysis has proved that there is a high significant correlation between the values of density and infra-density. There is a homogeneity between the method of density and infra-density measurements. Whereas the value of the correlation coefficient reached 0.85 and the mean of density 0.667 g/cm3 while the mean of infra-density was 0.668.

- This investigation carried out in 2010, to study the effect of ethanol / cyclohexan extract for heart wood of Biota orientalis, Pinus pinea and Abies cilicica, in inhibition mycelium growth to fungi Alternaria alternate and Fusarium solani and compared with fungicides (thiophanate-m , chlorothalonil and mancozeb) on PDA in laboratory. The obtained results showed that thiophanate-m gave the superior inhibition for F. solani ,where gave 100% inhibition at concentration 60 ppm. While the fungicide chlorothalonil gave the lowest inhibition to F. solani , where EC50 (73 ppm). At contrast, the fungicide chlorothalonil gave the highest inhibition to A.alternate at used concentrates. Where cause 100% inhabition at 100 ppm. Also the results showed that mancozeb gave moderate effect on both fungi, where EC50 37ppm an 58 ppm to F. solani and A. Alternate, respectively. On the other hand, the result showed that wood extract of study species gave significant inhibition to growth fungi compare with the control. the Ethanol/Cyclohexane-Extract of the heart wood of Biota orientales gave the superior effect inhibition to A. alternata ,where gave 100% inhibition at 150 ppm. While the Ethanol/Cyclohexane-Extract of the heart wood of (Abies cilicica) gave the highest inhibition to F.solani , where the percentage inhibition at concentrate 125 ppm were 100%. In contrast, the Ethanol/Cyclohexane-Extract of the heart wood of (Pinus pinea) gave moderate inhibition to A. Alternate, where EC50 (94 ppm). While gave the lowest effect in F. solani. Therefore we recommended to use the ethanol/ cyclohexane extract of the heart wood of Biota and Abies as Environment friendly fungicides.

- This investigation has established the Possibility of improving the values of physical-(Water absorption and cross-swelling after 2, 24, and 48 hours) and mechanical Properties (binding strength and cross-tensile strength) of Medium Density Fiber board (MDF) from Cotton Stems (Gossypium sp.) bonded with Urea formaldehyde resin (UF) by adding Parafin emulsion (0.5 % or 1 % to the dry weight of the fibers) when producing the Medium Density Fiber board (MDF) to reach the mean of values for the physical-(Water absorption and cross-swelling after 2, 24, and 48 hours) and mechanical Properties (binding strength and cross-tensile strength) of Medium Density Fiber board (MDF) in the European Standard.
