Replication Data for: PLIC-based contact line modeling for simulations of droplet impact onto smooth and structured surfaces
No full textSupplementary material to a submitted manuscript [full citation link follows when it is published] J. Wurst, M. Dreisbach, A. Stroh, J. Kriegseis, K. Schulte, "PLIC-based contact line modeling for simulations of droplet impact onto smooth and structured surfaces", referred to as "related publication" in the following:
A framework for the simulation of droplet impacts onto smooth and structured surfaces is developed within the in-house flow solver "Free Surface 3D" (FS3D). The code solves the incompressible Navier-Stokes equations in a one-field formulation and the Volume of Fluid (VoF) method. The dataset contains the raw simulation data (hdf5-files) of certain timesteps as well as images and text files directly used in the manuscript. The hdf5-data can be viewed with paraview by loading the fs3d.xmf file.
In particular, the data set contains the following cases:
-convergence tests results (textfile)
-sessile drop (textfile)
-square capillary (textfile)
-droplet impact smooth surface (textfile)
-grid study (textfile)
-droplet impact grooves (textfile, hdf5-files, png-files)
The simulation was performed as part of Germany’s Excellence Strategy
under Grant EXC 2075 - 390740016 within the subproject PN1-2(II)

Elimination of the baseline distortions in WURST-CPMG static experiments
No full textInternational audienceThe WURST-CPMG pulse sequence enables: (i) observing very broad spectra due to WURST excitation, and (ii) increasing the S/N ratio due to CPMG acquisition. However, strong baseline distortions may be observed, which make the extraction of the tensor information difficult. We propose a slight modification of the sequence, WURST-CPMGM, in which we skip the first M echoes and we only acquire the following ones. This simple treatment mostly eliminates the strong background signal and the ring down effects, leading to a flat baseline

REACTIONS OF ZR(ETA-6-BENZENE)(ALCL4)2 WITH ALKYNES - CYCLOOLIGOMERIZATION REACTIONS AND CRYSTAL AND MOLECULAR-STRUCTURE OF THE 7-MEMBERED METALLACYCLE [ZRCPH(CPH)4CPH][(MU-CL)2ALCL2]2
No full textBenzene solutions of the Zr(II) complex Zr(eta-6-benzene)(AlCl4)2 (1) catalyze the cyclotrimerization of 2-butyne to hexamethyl Dewar benzene (HMDB) and hexamethylbenzene (HMB) at room temperature. HMDB is the predominant initial product, followed by its isomerization to HMB. When diphenylacetylene was reacted with the (arene)zirconium(II) complex, the title metallacycle derivative was obtained, whose crystal and molecular structure was studied by X-ray diffraction methods.

Dima raineri is a medium-sized species (body length: 9.0– 13.5 mm) with a more convex, suboval body and shiny elytral intervals with very sparsely distributed thin setae (Figs 9 6–100). This species is characterized by the pubescence of the pronotal sides, which is short decumbent in anterior third or half and longer semi-erect posteriorly (Figs 154–155). This type of pubescence is present also in D. dusaneki sp. nov. but it differs in the more robust body and the shape of pronotum (wide, evenly convex, more rounded laterally; Figs 20–21). Similar species, D. macedonica, has the scutellum raised above the plane of the elytra (Figs 164–165), more distinctly double-sized pronotal punctation (punctures more like each other in size in D. raineri, larger differences between the size of punctures in D. macedonica; Figs 141–143, 154–155), head and pronotum surface in most cases more densely covered with pubescence, and the pubescence on the pronotal sides semi-erect along the whole margin length (although shorter at anterior half; Figs 141–143), and D. florinensis has also the punctures on pronotum of two distinct sizes and longer pubescence on the pronotal sides, which is of about the same length along the whole margin length (Fig. 129). Male genitalia is as in Figs 210–213. Intraspecific variability. The striae on the elytra are variable in this species. The holotype and some specimens are distinctly striate, but usually the striae are weakly developed and in some cases they are replaced by the rows of punctures, mainly in the posterior half. Some smaller specimens with the rather smooth elytra with sparse punctures (i.e. those from Grammos) may resemble D. elateroides but they can be easily distinguished by the almost smooth pronotum and oval scutellum. Additionally, the shape of antennomeres II and III is variable. Most specimens of D. raineri have antennomeres II and III elongate, but in some specimens they are more subtriangular (or at least antennomere III), similarly as in typical D. macedonica (see Wurst 1997). This variability led to the several misidentifications between these species (Schimmel & Platia 2008). Distribution. Albania (Mt. Tomorr), Greece (Vório Bóïo Mts., Grammos Mts., Pindos Mts.) (Fig. 244). First record for Albania. Remarks. Schimmel & Platia (2008) did not study the holotype of D. raineri described from the northern part of Pindos Mts. (deposited in the SMNS). Instead, they used a pale specimen of the another (but Peloponnesian) species as a representative of D. raineri and the diagnosis and all conclusions are based on that specimen (Fig. 84). Unfortunatelly, the specimen from the Peloponnese, which Schimmel & Platia (2008) thought was D. raineri, actually represented a species described newly in the same study from several other specimens as D. parnonensis (Schimmel & Platia 2008). What is more, as a result of the above mentioned confusion, specimens of the real D. raineri were newly described in the same study as D. pindosensis (Schimmel & Platia 2008; Fig. 99). Therefore, we herein synonymize Dima pindosensis Schimmel & Platia, 2008 under Dima raineri Wurst, 1997. The specimen from Mt. Tomorr, Albania, which was originally described as a part of the type series in D. macedonica, is definitely more like D. raineri than to D. macedonica (e.g. in the shape of the scutellum and in the pronotal punctation; Fig. 100), however, its pubescence of the pronotal sides is almost missing (Fig. 100). This specimen represents the northernmost known population of this species (Fig. 244). Additionally, we studied a dark brown female from the Elbasan county, Albania (locality label as follows: Albania, Librazhd, Shebenikut Qarishte env., 1500 m, 3.VII.2001, leg. P. Moravec; PCJM), which was identified as D. macedonica by Schimmel & Platia (2008) (Fig. 101). This specimen is much more like D. raineri in the pronotal punctation and pubescence of pronotal sides (Fig. 155). However, it is about 70 km farther north from the known D. raineri distributional range, closer to the area of D. macedonica (Fig. 244). This female might be a teratological specimen; it has the strongly transversely convex pronotum in the posterior half, distinctly convex basal and central parts of elytra and only weakly developed elytral striae (Fig. 101). Unfortunately, we are not able to properly determine this specimen to a species level until more material from that area is available for study.Published as part of Mertlik, Josef, Németh, Tamás & Kundrata, Robin, 2017, Revision of the flightless click-beetle genus Dima Charpentier, 1825 (Coleoptera: Elateridae: Dimini) in the Balkan Peninsula, pp. 1-63 in Zootaxa 4220 (1) on pages 30-31, DOI: 10.11646/zootaxa.4220.1.1, http://zenodo.org/record/467078
Effects of earthworms and organic litter distribution on plant performance and aphid reproduction
No full textHuman management practices and large detritivores such as earthworms incorporate plant litter into the soil, thereby forming a heterogeneous soil environment from which plant roots extract nutrients. In a greenhouse experiment we investigated effects of earthworms and spatial distribution of N-15-labelled grass litter on plants of different functional groups [Lolium perenne (grass), Plantago lanceolata (forb), Trifolium repens (legume)]. Earthworms enhanced shoot and root growth in L. perenne and P. lanceolata and N uptake from organic litter and soil in all plant species. Litter concentrated in a patch (compared with litter mixed homogeneously into the soil) increased shoot biomass and N-15 uptake from the litter in L. perenne and enhanced root proliferation in P. lanceolata when earthworms were present. Growth of clover (T. repens) was rather independent of the presence of earthworms and organic litter distribution: nevertheless, clover took up more nitrogen in the presence of earthworms and exploited more N-15 from the added litter than the other plant species. The magnitude of the effects of earthworms and organic litter distribution differed between the plant species, indicating different responses of plants with contrasting root morphology. Aphid (Myzus persicae) reproduction was reduced on P. lanceolata in the presence of earthworms. We suggest that earthworm activity may indirectly alter plant chemistry and hence defence mechanisms against herbivores
Modeling Aboveground–Belowground Interactions
No full textModels are powerful tools to capture the complexity of aboveground–belowground interactions in community ecology. Three general model aims can be distinguished: description, explanation, and prediction. These aims are covered by different model types such as conceptual models, graphical models, statistical models, functional–structural models, process-based models, reaction–diffusion models, cellular automaton models, and individual- or agent-based models. The available models of aboveground–belowground interactions always include interactions between root and shoot, and sometimes also trophic, competitive, facilitative, or mutualistic interactions. However, only very few of the existing aboveground–belowground models are community models that incorporate more than three species and more than one type of interaction. Furthermore, spatial relationships are rarely explicitly addressed. Thus, future approaches should (1) improve, simplify, and update current models, (2) extend current models to include more different interaction types and spatial relationships where this is justified by the model question, and (3) employ new modeling techniques such as game theoretical methods or Bayesian network models. Guidelines for model building are given based on the modeling cycle from question through concept, structure, and implementation to analysis and documentation. Close cooperation between empiricists and modelers will promote the success of future models of aboveground–belowground interactions
