postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Synthesis and systemic fungicidal activity of silicon-containing azole derivatives.
A new series of azole derivatives containing silicon were synthesized and evaluated for fungicidal activity against rice sheath blight by submerged application. Among them, 2-(4-fluorophenyl)-1-(1H-1,2,4-triazol-1-yl)-3-trimethylsilylpr opan-2-ol (9a) exhibited satisfactory efficacy at 12.5 grams per 10 ares.
متن کاملExperimental study of fracture mechanics in the aluminum matrix composites containing Fifteen percent silicon carbide particles
In this investigation ‚the fracture toughness of A356 containing15%SiC composite was studied. Al/SiC composites have been considered because of their mechanical and erosion properties .Low fracture toughness in Al/SiC as compared with Aluminium alloys is one of its disadvantage. In this study at first A356 alloy was melted in a smelting electrical furnace then poured into the mould. A356-15% Si...
متن کاملTheoretical Studies of Silicon - Containing Molecules
We report herein, a series of ab initio calculations on various SiH, and Si,H, species using generalized valence bond and configuration interactions methods. These results allow systematic estimation of the heats of formation and the enthalpies of reactions for these species. For SiH, compounds, the calculated and experimental energetics are in excellent agreement; we obtain D,,, (H,SiH) = 91.6...
متن کاملEffects of Aluminum, Silicon And Ferro Silicon Anti Oxidants in MgO C Refractories
Three different materials (aluminum, ferro -silicon and silicon) were used as antioxidants in order to prevent the decarburization process and to keep and/or increase the final properties in MgO-C refractories. Their effects were compared by measuring the physical and mechanical properties as well as oxidation and the resultant phases and microstructures, in the temperature range of 200-1600 ...
