Abstract [en]

This research has demonstrated the possibility of manufacturing models of Medium Density Fiber board (MDF)   from Cotton Seeds hulls as a Waste by-Product of Cotton with good Chemical Specifications comply with European specifications EN (DIN1999). Decrease in the average ability of models wood panels manufactured Medium Density Fiber board (MDF) of Cotton Seeds hulls to Formaldehyde release with the increasing Proportion of formaldehyde scavenger used, therefore the models containing 2% formaldehyde scavenger enjoy high-health quality. All models wood panels manufactured Medium Density Fiber board (MDF) of Cotton Seeds hulls characterized with good chemical specification (Formaldehyde release) Comply with European specifications EN (DIN1999) and enjoid a good health quality.

Abstract [en]

The liquid wastes come from milling the olive fruits, which are called the Olive Mill Wastewater, are disposed directly without any treatment. This causes a pollution of soil, groundwater, lakes, rivers and seas; it makes negative consequences on the elements of the ecological systems besides. Therefore, the treatment of these wastes and the ability to reusing them are urgent and necessary. The areas planted with olive trees yearly increase in Syria, this means that the annual average of olive oil production increases too. This causes the increasing of the main wastes average that comes from milling the olive fruits (The Olive Mill Wastewater). This investigation has established the Possibility of Rremediation of Environmental Hazards in Olive Oil mill wastewater by using the aeration, which can degrade the total polyphenol compounds in Olive Oil mill wastewater, which have bad effects on aqua environment to 77,76 % during 15 days.

Abstract [en]

The River red gum (Eucalyptus camaldulensis Dehn. ) is found in a lot of places in Syria, and the trees in Damascus- Daraa Road are in  good height, diameter and growth, so that we aimed to study some of the mechanical properties of its wood related to the most important modern uses of this wood in industry.

The study was done over Three trees, and three trunk masses of wood about 70 cm were taken from each tree from the beginning, the breast and the middle of the tree .

The results show that the wood of Rever red gum has the following mechanical properties:

-     The compression strength parallel to grain is medium (39.6 N/mm2), therefore, it is good in industries uses.

-     The bending factor is weak (1.44) , and its coherence is medium  (2.27).

-          The risistance of tensile strength was 40 N/mm2 .

-          Hardness (Janka) was 38.3 N/mm2.

So that we find out that the wood of River red gum is good and could be considered as a good wood with various uses and this spice is considered one of the promosing trees in our country for afforestration in zones like the stydy zones.

As for the variance, ther are significant effects of tacking masses from tree on the physical and mechanical properties of the wood.

The study was done over Three trees, and three trunk masses of wood about 70 cm were taken from each tree from the beginning, the breast and the middle height of the tree.

The results show that the wood of Rever red gum has the following physical properties:

  • It is hard, in which the density was 0.63 g/cm3, and this means that it is resistant to mechanical stress and sutable for using in building and engineering constructions.
  • The shrinkage is high.
  • As for the variance, there are significant effects of tacking masses from tree on the physical properties of the wood.

Abstract [en]

This investigation has established the possibility of producing Particleboard from Byrene (waste after the oil has been extracted from the second time with Naphtha). This product has good physical-[moisture content (6.1%). density (0.73). absorption and cross-swelling after 2 hours (29.8%:12.6%) and after 24 hours (40.1%:19.1%)] and mechanical properties [binding strength (8.3 N/mm2) and cross-tensile strength (0.23 N/mm2)] according to European Norms and is very economical.

Abstract [en]

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.
