Abstract This research investigates the influence of sodium hydroxide (SH) molarity on fly ash-slag-based geopolymer mortar’s workability, setting time, and compressive strength. The SH varies between 1M, 2M, 4M, 6M, 8M, 10M. mixture was proportioned to contain 30% slag as a substitution for ash, with alkaline activator binder (Al/Bi) ratio 0.45 silicate (SS/SH) 1.5. results showed that at rang...

The effect of Methyl Jasmonate (MJ, jasmonic acid methyl ether) at 10-10M concentrations on triticale kernels germination, seedling growth, changes in soluble carbohydrates content and composition, and activity of α-amylase was studied. MJ inhibited the germination of triticale kernels, possibly due to decreasing activity of αamylase, leading to the depletion of soluble carbohydrates in both em...

Static stretching has often been found to decrease performance in power and speed activities, but dynamic warm-ups usually increase performance. We examined the effects of a mini-band warm-up, a medicine ball warm-up, and static stretching on 10m and 20m sprint times, as well as overhead medicine ball throw performance. Twenty-four Division I female soccer players completed the three warm-ups a...

a specific inhibitor, the hypothesis that acetylcholine-induced coronary vasodilation is due to EDRF release was tested. Methods and Results. We studied the response of normal coronary arteries to acetylcholine (an endothelium-dependent vasodilator) and isosorbide dinitrate (an endothelium-independent vasodilator) in seven patients. The specificity of any vasodilator response was assessed by th...

Large and well defined variations exist between the distribution of mass and the light of stars on extragalactic scales. Mass concentrations in the range 10 − 10M⊙ manifest the most light per unit mass. Group halos in this range are typically the hosts of spiral and irregular galaxies with ongoing star formation. On average M/LB ∼ 90M⊙/L⊙ in these groups . More massive halos have less light per...

We investigate the incidence of major mergers creating Mstar > 10M⊙ galaxies in the dense environments of present-day groups and clusters more massive than Mhalo = 2.5 × 10M⊙. We identify 38 pairs of massive galaxies with mutual tidal interaction signatures selected from > 5000 galaxies with Mstar ≥ 5×10M⊙ that reside in a halo mass-limited sample of 845 groups. We fit the images of each galaxy...

We have compiled high-resolution position-velocity diagrams observed along the major axes of nearby spiral galaxies in the CO-line emission, and derived rotation curves for the inner regions of the galaxies. We have combined the inner rotation curves with the outer HI and optical rotation curves to obtain the total rotation curves. The inner rotation curves are characterized by a steep increase...

Purpose: To evaluate the effects of the methanol extract of Acanthus montanus on guinea pig trachealis muscle. Methods: Guinea pig tracheae were set up in 10 ml organ baths. The effect of the methanol extract of Acanthus montanus (0.5 8 mg/ml) on the spontaneous tone of the trachea and carbacholprecontracted trachea in the absence and presence of propranolol, glibenclamide and procaine was stud...

(2) The VERITAS Collaboration–see S.P.Wakely's paper " The VERITAS Prototype " from these proceedings for affiliations Abstract The Whipple 10-m telescope was used to observe M87 since 2000. No significant gamma-ray signal was found and upper limits compared to the HEGRA detection suggest the source may be variable. We found weak evidence for a correlation with the X-ray activity in 2000-2001 b...
