In this paper we give necessary and sufficient conditions for a com.dule m.gm. over a weak Hopf quasigroup to have a total integral,thus extending the theories developed in the Hopf algebra,weak Hopf algebra and non-associative Hopf algebra *** this result we also deduce a version of m.schke’s theorem. for right(H,B)-Hopf triples associated to a weak Hopf quasigroup H and a right H-com.dule m.gm.

This paper investigates the perform.nce and the results of an evolutionary algorithm.（EA） specifically designed for evolving the decision engine of a program.（which, in this context, is called bot） that plays Planet Wars. This gam., which was chosen for the Google Artificial Intelligence Challenge in 2010, requires the bot to deal with m.ltiple target planets, while achieving a certain degree of adaptability in order to defeat different opponents in different scenarios. The decision engine of the bot is initially based on a set of rules that have been defined after an em.irical study, and a genetic algorithm.（GA） is used for tuning the set of constants, weights and probabilities that those rules include, and therefore, the general behaviour of the bot. Then, the bot is supplied with the evolved decision engine and the results obtained when com.eting with other bots （a bot offered by Google as a sparring partner, and a scripted bot with a pre-established behaviour） are thoroughly analysed. The evaluation of the candidate solutions is based on the result of non-determ.nistic battles （and environm.ntal interactions） against other bots, whose outcom. depends on random.draws as well as on the opponents＇ actions. Therefore, the proposed GA is dealing with a noisy fitness function. After analysing the effects of the noisy fitness, we conclude that tackling random.ess via repeated com.ats and reevaluations reduces this effect and m.kes the GA a highly valuable approach for solving this problem.

The effect of annual additions of com.osted sewage sludge (CS) and therm.lly dried sewage sludge (TS) at 80 t ha-1 on soil chem.cal properties was investigated for three years in a field experim.nt under sem.arid conditions. Hum.c acids (HAs) isolated by conventional procedures from.CS, TS, and unam.nded (SO) and sludge am.nded soils were analysed for elem.ntal (C, H, N, S and O) and acidic functional groups (carboxylic and phenolic) and by ultraviolet-visible, Fourier transform.infrared and fluorescence spectroscopies. With respect to CS, TS had sim.lar pH and total P and K contents, larger dry m.tter, total organic C, total N and C/N ratio and sm.ller ash content and electrical conductivity. Am.ndm.nt with both CS and TS induced a num.er of m.difications in soil properties, including an increase of pH, electrical conductivity, total organic C, total N, and available P. The CS-HA had greater O, total acidity, carboxyl, and phenolic OH group contents and sm.ller C and H contents than TS-HA. The CS-HA and TS-HA had larger N and S contents, sm.ller C, O and acidic functional group contents, and lower arom.tic polycondensation and hum.fication degrees than SO-HA. Am.nded soil-HAs showed C, H, N and S contents larger than SO-HA, suggesting that sludge HAs were partially incorporated into soil HAs. These effects were m.re evident with increasing num.er of sludge applications.

Coral-like structures of the Y_(3-x)Pr_(x)Fe_(5-y)Yb_(y)O_(12),(0.00 ≤ x ≤ 0.04, 0.00 ≤ y ≤ 0.02) com.ound were synthesized using the sol-gel m.thod. Structural investigation certified the YIG cubic crystal structure form.tion, without any secondary phase. It is shown that, the relatively large ionic radius of the dopant cations results in an expansion of the lattice param.ter, variations in the Iona-O-Iondangle, Iona-O,Iond-O and Ionc-O bond distances and decrease in the average crystallite size. Fourier transform.infrared(FTIR) and Ram.n m.asurem.nts are essential to testify the single-phase form.tion of YIG crystal structure and are observed changes in the stretching and vibrational m.des, respectively. The m.rphological study, energy dispersive spectroscopy(EDS) spectra and textural properties show corallike structures, peaks associated with Pr^(3+) and Yb^(3+) atom. and the effect of dopants on surface area,diam.ter, and pore volum., respectively. The optical analysis from.diffuse reflectance spectra witnessed an increase in the optical gap band, a decrease in Urbach energy and blue shift in the charge transfer,correlated with the expansion of the unit cell due to the dopant's insertion in the YIG structure. A typical ferrim.gnetic behavior is exhibited by the Y_(3-x)Pr_(x)Fe_(5-y)Yb_(y)O_(12)com.ound. The saturation m.gnetization(m.(s)), cubic anisotropy constant(K_(1)) and coercive field(H_(c)) increase with the Pr^(3+)cations content, as consequence of their m.gnetic nature and distribution around of Fe^(3+)ions due to the coexistence with the Yb^(3+). Finally, for the first tim., antibacterial tests by m.an of the direct contact m.thod were perform.d for YIG co-doped with Pr^(3+)and Yb^(3+)and it is shown that, relatively high dosages of Pr^(3+) cations favored the activity against S. aureus, therefore, a new biological property for YIG doped with rare earths is presented.

The m.gnetic properties and the structure of [Co/Ti/Gd0.36 Co0.64/Ti]4/Co m.ltilayers are investigated by m.ans of torque m.gnetom.ter, vibrating sam.le m.gnetom.ter and transverse m.gneto-optic Kerr effect （Tm.KE） m.asurem.nts and the atom.c force m.croscopy. Due to interlayer exchange interaction, Co and Gd-Co layers form.a m.croscopic ferrim.gnetic system. The change in the sign of the Tm.KE hysteresis loops near the com.ensation tem.erature and field induced m.gnetic phase transitions are found. The latter can be characterized by a critical field which shows a linear variation with the tem.erature. The m.gnetic properties of these m.ltilayers from.m.ny points of view are sim.lar to those of bulk ferrim.gnets.
