Micromechanical investigation of granular ratcheting using a discrete model of polygonal particles

Particuology 2008年第6期6卷 390-403页

We use a two-dimensional model of polygonal particles to investigate granular ratcheting. Ratcheting is a long-term response of granular materials under cyclic loading, where the same amount of permanent deformation is accumulated after each cycle. We report on ratcheting for low frequencies and extremely small loading amplitudes. The evolution of the sub-network of sliding contacts allows us to understand the micromechanics of ratcheting. We show that the contact network evolves almost periodically under cyclic loading as the sub-network of the sliding contacts reaches different stages of anisotropy in each cycle. Sliding contacts lead to a monotonic accumulation of permanent deformation per cycle in each particle. The distribution of these deformations appears to be correlated in form of vortices inside the granular assembly.

nutrient retention and release in coarse woody debris of three important central European tree species and the use of nIRS to determine deadwood chemical properties

Forest Ecosystems 2018年第3期5卷 296-310页

作者： Steffen.herrmann Jurgen Bauhus Faculty of Environment and natural Resources University of Freiburg Tennenbacherstr.4D-79106Freiburg i.Br.Germany Thunen Institute of Forest Ecosystems Alfred-M611er-Strabe 1Haus41/4216225EberswaldeGermany

Background: Coarse woody debris(CWD) is very important for forest ecosystems, particularly for biodiversity and carbon storage. Its relevance as a possible reservoir and source of nutrients is less clear, especially in central ***: Based on a chronosequence of known ages of logs, we analyzed the nutrients stored in CWD of Fagus sylvatica, Picea abies, and Pinus sylvestris at different sites in Germany. To quantify nutrient concentrations, we assessed the use of near Infrared Reflectance Spectroscopy(nIRS) to determine the chemical properties of ***: nIRS models were suitable to predict concentrations of C, n, P, lignin and extractives. Concentrations of most nutrients increased with mass loss, with the exception of potassium, which decreased for beech and pine and remained relatively constant for spruce. The highest nutrient concentrations(n, P, S, Ca and Mn, except Mg and K) were generally observed in highly decomposed spruce logs. The net effect of decreasing CWD mass and increasing nutrient concentrations was either a decreasing(n, P and K in beech; P, Mg, K and Mn in pine), constant(S, Ca and Mg in beech; n, S and Ca in pine) or increasing amount of nutrients(n, P, S and Ca in spruce; Mn in beech) in the logsover the course of decomposition. The C/n ratio decreased for all tree species, most markedly for spruce from ca. 1000 at the beginning of the decomposition process to 180 at 36 years. The n/P ratio converged to a value of about 30 forall three species. Lignin concentrations increased for spruce and beech and remained constant for ***: Our results indicate that most nutrients remain in CWD for long periods. nutrients may be used and cycled by microorganisms within CWD, but with the exception of P(in beech), Mg(in pine) and K(in beech and pine), there appears to be little net nutrient export until two thirds of the mass is lost. Instead, n, P, S and Ca were accumulated in spruce logs, indicating that CWD became a net sink rathe

Thulium：YAG VapoEnucleation of the prostate in large glands： a prospective comparison using 70- and 120-W 2-μm lasers

This study compared the efficacy of 70- and 120-w 2-μm thulium：YAG VapoEnucleation of the prostate （ThuVEP） for patients with benign prostatic obstruction （BPO）. A prospective analysis of 84 patients with symptomatic BPO and prostatic enlargement （t〉 60 ml） who underwent either 70-w （n=44） or 120-w ThuVEP （n=40） non-randomly was carried out. Patient demographics and perioperative and 12-month follow-up data were analysed. The mean prostate volume was 79.90---27.49 ml in patients who had received 70-w ThuVEP, which was less than in those who had received 120-w ThuVEP （88.53＋-25.10; P=0.033）. The mean enucleation （resected weight/laser time, 2.16±1.21 g min-1 vs. 1.23±0.60 g min-1; P=-0.013）, operation efficiency （resected weight/total operation time, 0.76±0.35 g min-1 vs. 0.42＋-0.27 g min-1; P=-0.000） and percentage of resected tissue （66.93%±22.79% vs. 45.41%±23.33%; P=-0.000） were higher with 120-w treatment compared to 70-w ThuVEP. One patient （1.2% of total patients）（in the 120-w group） required a blood transfusion postoperatively. Sixty-one patients （73%） were available for review at the 12-month follow-up time point. The quality of life （QoL）, International Prostate Symptom Score （IPSS）, maximum urinary flow rate （Qmax）, postvoiding residual urine （PVR） and prostate volume improved significantly after treatment （P≤ 0.035） and were not significantly different between those treated with the different devices （70- and 120-w）. The median prostate volume reduction was 81.70% and 82.19% with 70- and 120-w ThuVEP, respectively. The incidence of complications was low and did not differ between groups treated with the different devices. Two patients （2.4%）（one per group） had a bladder neck contracture at the follow-up. ThuVEP is a safe and efficacious procedure for the treatment of symptomatic BPO. The incidence of complications was low with both devices. The 120-w thulium：YAG device enhances the effectiveness of Th,VEP with reeard to the oercentaee of resected tissue

The size selectivity and usability of three codends were quantified and compared for the first time in the inshore northern shrimp(Pandalus borealis)trawl fishery of Iceland using the covered codend method:a conventional diamond-mesh codend(T0),conventional square-mesh codend(T45),and a 90◦turned mesh codend(T90)constructed of four panels and with shortened lastridge ***,wanting to increase the average-individual size of captured shrimp,had requested the T90 codend to be compared with conventional codends for consideration in the *** showed that,on average,the T45 and T90 codends had better size selectivity than the T0 codend in terms of releasing individuals smaller than 13 mm carapace length(Minimum References Size;MRS).The T90 codend retained significantly less northern shrimps between 9 and 19 mm than the T0 codend and between 15 and 19 mm than the T45 *** significant difference of size selectivity between T45 and T0 codends was *** three codends presented high retention ratios of northern shrimps above MRS(>63%)for the population ***,the T0 codend was not effective at sorting out small northern shrimps;at least 86%of northern shrimps smaller than 13 mm were retained in the T0 codend if *** from T45 and T90 codends had a lower proportion of shrimp below *** discarding of undersized northern shrimps is prohibited in Iceland and fishers wanted to catch on average larger shrimp,using the novel T90 codend would enable fishers to use their quotas more efficiently.
