Recycling of domestic wastewater treated by vertical-flow wetlands for irrigation of two consecutive Capsicum annuum generations

Due to water scarcity, there is great interest in reusing various nutrient-rich wastewaters. The aim of this article is consequently to evaluate if domestic wastewater treated by various wetland systems can be successfully recycled to irrigate generations of commercial crops such as Chilli (Capsicum annuum) grown in compost within a laboratory environment to obtain a cultivar adapted to domestic w

Dioxidomolybdenum(VI) and -tungsten(VI) complexes with tripodal amino bisphenolate ligands as epoxidation and oxo-transfer catalysts

The molybdenum(VI) and tungsten(VI) complexes [MO2(L)] (M = Mo (1), W (2), H2L = bis(2-hydroxy-3,5-di-tert-butybenzyl)morpholinylethylamine) were synthesized and the complexes were used to catalyze oxotransfer reactions, viz. sulfoxidation, epoxidation and benzoin oxidation. For comparison, the same reactions were catalyzed using the known complexes [MO2(L′)] (M = Mo (3), W (4), H2L′ = bis(2-hydro

Three-dimensional microplate formation with evaporating nanoparticle suspensions on superhydrophobic surfaces

The concept of evaporation driven self-assembly of nanoparticles is exploited to fabricate three dimensional microstructures on textured superhydrophobic surfaces. The evaporative droplets always remain in Cassie–Baxter state during the process of drying. However, the wetting transition from Cassie to Wenzel state has been observed for pure water drop on similar surfaces. After complete evaporatio

Impact of basic angle variations on the parallax zero point for a scanning astrometric satellite

Context. Determination of absolute parallaxes by means of a scanning astrometric satellite such as Hipparcos or Gaia relies on the short-term stability of the so-called basic angle between the two viewing directions. Uncalibrated variations of the basic angle may produce systematic errors in the computed parallaxes. Aims. We examine the coupling between a global parallax shift and specific variati

Sven Nilsson and the postglacial fauna of Scania

The Lund professor Sven Nilsson achieved international fame in the nineteenth century in such diverse subjects as geology, zoology, and archaeology. This man of contrasts is described as brilliant but temperamental and touchy, assertive, with a fondness for sensation but simultaneously highly sensitive to criticism. His research on faunal history was pioneering, and many of the results are still v

Long-term retromuscular and intraperitoneal mesh size changes within a randomized controlled trial on incisional hernia repair, including a review of the literature

Abstract: Purpose Ingrowth of fibroblasts in a polypropylene mesh may cause contraction and a later recurrence. We assessed mesh contraction in intraabdominal and retromuscular implantation after incisional hernia repair. Methods: A cohort of patients within an RCT on laparoscopic (LHR) versus open hernia repair (OHR) had their mesh borders marked with metal clips. X-ray was performed on postopera

Validation of a Mitotic Index Cutoff as a Prognostic Marker in Undifferentiated Uterine Sarcomas

Undifferentiated uterine sarcomas (UUS) are a heterogenous group of high-grade mesenchymal tumors. Although these tumors are highly aggressive, a subset of patients may experience long-term survival. These tumors have previously been divided morphologically into uniform and pleomorphic types. A previous study demonstrated that a mitotic index cutoff of 25 mitoses/10 high-power fields (correspondin

Interactions between cultured bovine arterial endothelial and smooth muscle cells; further studies on the effects of injury and modification of the consequences of injury

The hypothesis that cells of the arterial wall might modify the consequences of arterial injury was tested. Bovine aortic endothelial cells (EC) or smooth muscle cells (SMC) were exposed to the two toxic stimuli 3,4-benzo(a)pyrene (BP) and dimethylsulfoxide-soluble particulate matter from cigarette smoke (DSP) or factors released from platelets. The modification of the injury caused by these subst

Low-Frequency Synonymous Coding Variation in CYP2R1 Has Large Effects on Vitamin D Levels and Risk of Multiple Sclerosis

Vitamin D insufficiency is common, correctable, and influenced by genetic factors, and it has been associated with risk of several diseases. We sought to identify low-frequency genetic variants that strongly increase the risk of vitamin D insufficiency and tested their effect on risk of multiple sclerosis, a disease influenced by low vitamin D concentrations. We used whole-genome sequencing data f

Muon reconstruction performance of the ATLAS detector in proton–proton collision data at s=13 TeV

This article documents the performance of the ATLAS muon identification and reconstruction using the LHC dataset recorded at s=13 TeV in 2015. Using a large sample of J/ ψ→ μμ and Z→ μμ decays from 3.2 fb- 1 of pp collision data, measurements of the reconstruction efficiency, as well as of the momentum scale and resolution, are presented and compared to Monte Carlo simulations. The reconstruction

Measurement of the transverse momentum and ϕη∗ distributions of Drell–Yan lepton pairs in proton–proton collisions at √ s = 8 TeV with the ATLAS detector

Distributions of transverse momentum pT ℓℓ and the related angular variable ϕη∗ of Drell–Yan lepton pairs are measured in 20.3fb-1 of proton–proton collisions at √ s = 8 TeV with the ATLAS detector at the LHC. Measurements in electron-pair and muon-pair final states are corrected for detector effects and combined. Compared to previous measurements in proton–proton collisions at √ s = 7 TeV, these

Differential studies of inclusive J/ψ and ψ(2S) production at forward rapidity in Pb-Pb collisions at √sNN = 2.76 TeV

The production of J/ψ and ψ(2S) was studied with the ALICE detector in Pb-Pb collisions at the LHC. The measurement was performed at forward rapidity (2.5 < y < 4) down to zero transverse momentum (pt) in the dimuon decay channel. Inclusive J/ψ yields were extracted in different centrality classes and the centrality dependence of the average pt is presented. The J/ψ suppression, quantified with th

Environmentally driven extinction and opportunistic origination explain fern diversification patterns

Combining palaeontological and neontological data offers a unique opportunity to investigate the relative roles of biotic and abiotic controls of species diversification, and the importance of origination versus extinction in driving evolutionary dynamics. Ferns comprise a major terrestrial plant radiation with an extensive evolutionary history providing a wealth of modern and fossil data for mode
