Two models were developed to evaluate total volume under and over-bark of Blackwood (Acacia melanoxylon R. Br.) stand trees. By variance analysis regarding volume with and without bark it was confirmed that trees age is responsible for 48 to 50% of its volumetric behaviour. Considered the averages of those variables and regarding the three homogeneous groups of the studied sites, a single model...
− This paper shows utility of phasor total unbalance power as a tool to explain working of unbalanced power systems. Conditions under shunt capacitors used to compensate reactive power can deteriorate the efficiency in three-phase four-wire unbalanced at loads power systems are described. Reactive phenomenon is studied using Emanuel ́s positive-sequence fundamental-frequency reactive power, incl...
Catalan's sequence of numbers {C„}% = {1,1,2,5,14,42,...} (nr.1459 and ,4000108 of [14]) emerges in the solution of many combinatorial problems (see [2], [4], [5], and [16] for further references). The moments ju2k of the normalized weight function of Chebyshev's polynomials of the second kind are given by Ck /2 (see, e.g., [3], Lemma 4.3, p. 160 for /= 0, and [17], p. II3). This sequence also ...
To study the incorporation of radioactive phosphorus by Lactobacillus leichmannii growing in media with and without vitamin B12, the cells were grown either in a complete medium (broth plus liver extract) or in a test medium (Skeggs et al.: J. Biol. Chem., 176, 1459, 1948) with a limiting quantity of B12. After 48 hours' growth, the cells were harvested, washed, and resuspended in the test medi...
ISSN:0975-1459 Sustained release microcapsules of acetazolamide, a short half life carbonic anhydrase inhibitor, was developed to reduce the frequency of drug administration, ease of dose adjustment and improve patient compliance. In this study, sustained release microcapsules of acetazolamide was prepared by solvent evaporation techniques using Eudragit RL/RS as polymer and particle size, enca...

We present new results of a 12CO(J=1-0) imaging survey using the Atacama Compact Array (ACA) for 31 HI detected galaxies in IC 1459 and NGC 4636 groups. This is first CO loose galaxy obtained well-resolved data (~0.7-1.5 kpc) total 16 two environments. By comparing our ACA with UV data, we probe impacts group environment on cold gas components (CO gas) star formation activity. find that and/or ...
