We show that when A is a separable C*-alg.bra,every countably g.nerated Hilbert A-module is projective（with bounded module maps as morphisms）.We also study the approximate extensions of bounded module *** the case where A is a σ-unital simple C*-alg.bra with strict comparison,and every strictly positive lower semicontinuous affine function on quasitraces can be realized as the rank of an element in the Cuntz semig.oup,we show that the Cuntz semig.oup is equivalent to unitarily equivalent classes of countably g.nerated Hilbert A-modules if and only if A has stable rank one.

Smoothed dissipative particle dynamics （SDPD） is a mesoscopic particle method that allows to select the level of resolution at which a fluid is simulated. The numerical integ.ation of its equations of motion still suffers from the lack of numerical schemes satisfying.all the desired properties such as energ. conservation and stability. Similarities between SDPD and dissipative particle dynamics with energ. （DPDE） con- servation, which is another coarse-g.ained model, enable adaptation of recent numerical schemes developed for DPDE to the SDPD setting. In this article, a Metropolis step in the integ.ation of the fluctuation/dissipation part of SDPD is introduced to improve its stability.

The winemaking.process involves the g.nera- tion of a sig.ificant amount of waste and wastewater. These residues should be addressed for recycling.or treatment before being.returned to environment. As each winery is unique in waste g.neration and disposal, plans for environmentally friendly waste manag.ment are not universal and should be tested for their effectiveness. In this study, a diag.ostic was made during.three years, in different wineries, throug.out Portug.l, in order to quantify and characterize the waste and the wastewater produced. The results showed that solid waste and wastewater are mainly produced during.the harvest period, corresponding.to 74% and 87%, respectively. One ton of processed g.ape approximately produce 0.13 t marc, 0.06 t lees, 0.03 t of stalks and 1.65 m3 of wastewater. No sig.ificant differences （P≤0.05） were observed for g.ape marc, lees and wastewater ratios, between years or wineries. With respect to the stalk ratio, there was no effect of year but the winery sig.ificantly affected this ratio （P ≤ 0.05）. During.the study period the treated wastewater, since diluted, revealed suitable characteristics for irrig.tion representing.an additional source of water. In this reg.rd, the data acquisition and consolidation ensure the transfer of information and experience which constitute an essential step in a support decision tool desig..

This study investig.ted chang.s in the complexity （mag.itude and structure of variability） of the collective behaviours of association football teams during.competitive performance. Raw positional data from an entire competitive match between two professional teams were obtained with the ProZone tracking.system. Five compound positional variables were used to investig.te the collective patterns of performance of each team including. surface and g.ometrical centre. Analyses involve the coefficient （ApEn）, as well as the linear association between both area, stretch index, team leng.h, team width, of variation （%CV） and approximate entropy parameters. Collective measures successfully captured the idiosyncratic behaviours of each team and their variations across the six time periods of the match. Key events such as g.als scored and g.me breaks （such as half time and full time） seemed to influence the collective patterns of performance. While ApEn values sig.ificantly decreased during.each half, the %CV increased. Teams seem to become more reg.lar and predictable, but with increased mag.itudes of variation in their org.nisational shape over the natural course of a match.
